3. The Role of Environment Lighting Design ( Interior Design and Lighting ): Lecture, we're going to be
learning about the importance and the Role of Lighting
in interior design. Most probably whenever
you walk into a space, the first thing that
you come across as the architectural
arrangement, the furniture, the paint color, all of these things which
actually grab your attention, but often quite oblivious
to the fact that lighting is actually altering your perception of
all of these things. Now, in this current lecture, we're going to be tackling some important points that
you need to keep in mind. Because they serve as the
foundation in terms of the importance of Lighting
as part of Interior Design. Now, here are some
key ways in which lighting plays a crucial
role in interior design. Starting off with setting
the mood and ambiance. Now, lighting can create different moods and
ambience within a space. Whenever you walk into a space and you find out that the places them and you have a warm tone which is
yellowish in color. All of a sudden
you have this vibe that this space is quite cosy, suitable for sleeping,
for example. On the other hand,
if you walk into a space and it's quite vibrant, the light is bright and
it's quite white and color, and it's radiating quite illuminated brightly
and intensely. It gives you that vibe
of energy, productivity. Things shouldn't
be done, movement. So these cues are
actually picked up on by our brains due to
the influence of light. Some places, for example, which are warm tone, they can create a cozy feeling
while cool toned light, which was white
and color. White. White can create an
energetic atmosphere. It's also can be used to create specific themes such
as the movie theaters, for example, its mood,
or certain ambiance. Let's say you're
walking into a theater, the entire stage is dark. However, the stage
is quite bright and illuminated to put
some attention and focus on the
actors, for example. On the other hand, if
you walk into a museum, you'll notice that
every single piece of Art is radiating. It's glowing. Not because of the
piece of Art by itself, but actually due
to the spotlights which are quite placed under every single one
of these pieces of artwork to enhance the features, to shed light and expose the
qualities of those features. Now, this is the smart use of lighting to help the individuals receive certain cues in terms of the vibe, the experience, the energy level
that the designer would like such occupants to be receiving and experience
of the same time. Now, the second key point is highlighting
designed features. If you do have a pieces of Art or if you do have
certain qualities within a certain space and you
would like to draw attention to light is working
in your favor. And this current case by
strategically placing Lamps, light fixtures, and shedding, literally shedding light
on that specific Fixture. You're going to enhance
the qualities and the features that are going to be picked up on
by your visitors. For example, if you
haven't museum, a library, a car showroom, or you're working in
retail, for example, you have a new bag, for example, which is going
to be released to the public. And you're putting
it on display, arranging spotlights to shed some quality light with a certain tone, a
certain intensity, a certain ambiance to
expose the qualities of the new bag or the new piece of accessory that you would like
to display to the public. Think about the new
watch, for example, whenever you walk into a jewelry store and they
have a brand new watched it, put it on display, glass window begun
a certain piece to hold that watch and
Lighting is surrounding that what creating and
certain effect which makes you perceive that piece
of jewelry as luxurious. And whenever you
buy that piece of jewelry and you walk
out of the store, you notice it's a bit dull compared to the condition
that you have seen it. Well, it's the same
piece of jewelry, it's the same watch, but
the lighting has changed. So keep that in mind. Number three and
enhancing functionality. If you are reading,
you're cooking. You have a soccer
field, for example. Obviously to be able to
use those spaces properly, to properly function
within those spaces. Quality lighting is required
in order for you to experience the use of
those spaces fully. Number four, which is
creating visual interests, were learning can
add visual interest. A space creating patterns. Whenever you have a festival, you notice certain
cascade of Lights. A contrast between
light and shadow. If you have a small
tree, for example, and then you place
a lamp in front of the three at a certain angle, you're going to have a huge
shadow behind the three, creating a very, very
dramatic effect. So this play between
light and shadow, you're able to create
visual patterns which is going to spark
interest in the viewers, the visitors of whatever
venue that you're dealing with for improving
energy efficiency, especially nowadays when it
comes to sustainability, you should be able
to use lighting in a smart way such that enhance the utilization of renewable resources on
non-renewable resource
4. Lighting Terminology and Technical Concepts: To be learning about key important lighting
Terminology and Technical Concepts that every single lighting
professional, whether you are an
engineer and architect or just someone who's
going to be picking up a bulb for installation. You need to be familiar with these concepts because
they are crucial for the successful approach in terms of Environment
Lighting Design. Starting things off with Lumens, a measure of the amount of visible light emitted
by a light source. The higher the lumens, the brighter the light. So it's an indicator
of strength. The stronger the lighting, the higher the lumens. Color temperature, a measure of the color of light emitted
by enlarge light source. It is measured in Kelvins
and ranges from warm tones, 2,700 kelvins up
to 3,000 Kelvins, it will give you the
color of yellowish, orangeish, similar to sunlight. With them that shade you going
to go from yellow, orange. And these are the
various ends of the spectrum that you're
going to be experiencing with a warm tone,
2700-3 thousand Kelvin. And cool, which is mainly
visualized as white light. And there are degrees
of whiteness. Let's say you do have bright
white, slightly dimmer. And there's a range. Now with them, the
course and the within the Resources Library of
the current course will be adding a couple of
helpful visuals to help you understand the
differences between and see the relationships
between the Kelvins and the actual visual
light differences. Wattage, which represents power, the amount of energy consumed, a measure of the amount of energy consumed by
a light source. The higher the wattage, the more the energy the
light source he uses. Whenever you want to
buy a bulb and you're on the box and the
packet of the ball, we're going to find a number
which says 60 W and W. W. This W stands for parts, which is the amount of energy measured in joules
and a single second. So it's the amount of
light energy per second, the specific light bulb
which is going to be providing you with foot candles, a measure of the amount of
light that falls on a surface. It is used to determine the required illumination
levels for different tasks. So based on different tasks, the amount of light falling
down a certain surface, Let's say you have a table and then you put an a
bulb in front of it. The area of the table which is going to be under the
influence of flight, is going to be measured
and foot candles, and it measures the amount
of light that actually folds on that specific surface. Color rendering, or
also known as CRI, which is color rendering index. It's a comparison
between natural light, sunlight and that
specific light source. It's a measure of how
well a light source reproducers colors in
comparison to natural light. So if you expose a circle light source and
you put it on daylight, how close are the rays of radiation from the
source and sunlight? Are they close to each other or they are quite
different from each other and how good the source
is in terms of adjusting rendering light to match
the natural sunlight. So the higher the CRI, the better the
color rendering or the color adjustment to
match natural light. Lighting layers,
which is the use of multiple lighting sources
such as ambient lighting, task lighting,
accent lighting to create a balance and visually
appealing lighting scheme. Lot layering from
the world layers. You're going to use
multiple sources together to create
levels of light. Think about it this way. You got one spotlight over here and another
spotlight over here. I'm both of them, they are
focusing on a certain point. That specific point will
be brighter than both of them separately because we're combining the
illumination from both. So that's light layering. Let's say you do have a certain space such
as a living room. You do have a desk and you're
going to place at dusk light than you do have couple of spotlights on the ceiling. You do have wall Lights. These are going to be creating different types of
sources for light. Hence, they are going to
be layering on top of each other such that if you
turn one of them off, you're going to have a
different experience. Turn two of them off. You're going to have a
different experience until the point where you
shut all of them off, the entire space is
going to be dark. Reversed the
process, turn one of them on different experience, turn both of them on Three of them, four of
them, all of them on, just to have changed
as an ambience, changes in the atmosphere, changes in the level
of energy being exposed to that specific space. You can try it out by yourself. If you have a
certain living space and you do have a variable, various sources such
as a desk lamp and then you do have a bulb
and then you do have, let's say, Fixture on the wall which is
providing you with Light. Try to turn them on
and off alternatively, and with different combinations. And you're going
to be experiencing different levels of
ambience within that space. This is an example
of light layering. Now we're going to go
forward the beam angle. Take a look in the
image over here. Beam angle, which
is the width of the light beam emitted
by a light source. It is measured in
degrees and determines how wide or narrow
the Lights predators. If you take a look at this
light source over here, think about it as
basically a ray of light. And then you are going to
be spreading the light. This distance is going
to be your beam angle. This beam angle
depends on the source. It can be narrow,
focused or spread, light, less focused, but
covers a bigger area. A beam angle could be utilized to help you understand
the area of coverage. Are you going to be focusing
light on specific small area or the beep Angular's high and is going to be spread
over a bigger area. Then you have the glare, which is the
excessive brightness or reflection of light that causes the visual discomfort whenever you're taking
a look at an object, and then this object
is quite too bright. How do you feel? Your eyesight is
going to be sore. Why? Because of the glare, that brightness, which
is quite uncomfortable. It is important to consider when designing lighting schemes where interior spaces to avoid any glare specialty on
reflective surfaces. If you've got
metallic objects and you're using light extensively, is going to be bouncing
off the surfaces, the metallic surfaces and into the eyes of the people
occupying that space, creating a glare which
is at this comfort, which is, which is a
level of discomfort. Visual stimulus, ballast, which is a device that controls the flow of current
to a light source, often used and fluorescent or high-intensity
discharge Lighting. Think about it as a
control mechanism. Ballast could come in
various different options. You get knobs, you got
controls, capacitors, whatever the mechanism is, they fall under balanced, which is a mechanism to
control the current, which is electricity
going through the wire into the bulb to adjust the level of
brightness and illumination. And finally, led, which
is light emitting diode. Often you hear this
in terms of LED TVs, LED bulbs, LED cars, or the spotlights
wherever it is. Often we are bombarded
with the word LAB and it's important to
know what does it mean. Says light emitting diode, which is a lighting
technology that uses a semiconductor
to produce light, which is basically a
material that you are going to utilize to
release electricity. And this electricity will
allow you to generate light, which is more energy
efficient and longer-lasting than
traditional Lighting?
5. The Impact of Lighting on Health and Wellbeing as part of Environment Lighting: Welcome back with
this current lecture in which we are
going to learn about the Impact of Lighting
on Health and Wellbeing. It's not just simply a
matter of an ambulance or athletics or
architectural appeal. Your own well-being is
actually impacted by light. Let's take a look at this. First of all, your
crew cardiac rhythm. You're sleeping pattern. Let's go through these
paragraphs 1 at a time. I've placed them for you
with access in details such that whenever
you're watching a lecture, you can pause, you can take down some
notes and you can compile your own notes from the course in a concise manner
for sake of convenience. Ricardian rhythms, which is
basically sleeping patterns, a lighting is a key factor in regulating our quick
Hadean rhythms, which are our internal
24 h biological clock that helps us regulate our
sleep and waking cycles. Hormone production and
other bodily functions. Exposure to natural light during the day and minimal exposure to artificial light at night can help keep our circadian
rhythms and sink. Promoting a healthy
sleep patterns and overall well-being. Take a look at the image. There's a form of therapy, which is light therapy. When you are sleeping at
night, before you sleep, it's quite advice that
you do not expose your eyes to blue race
such as mobile phones, TVs, and it's worse of light. Why? Because before
you get to sleep, your brain is going to be releasing a hormone
called melatonin. This hormone is
the sleep hormone. Often people with insomnia, they are deprived
from this hormone. They are not able to sleep. Melatonin is quite
necessary to sleep and wonky condition in order to have a proper secretion
of melatonin is through the lack of
surrounding light. If there is no light around you, your melatonin production
is going to increase. There is light specifically
blue rays, it will drop. So you understand the
impact of flight and your own health,
specifically sleep. Now, when it comes to feeling
happy and full of energy, you do have an another hormone, which is serotonin, often known
as the happiness hormone. Take a look at this
current schematic. You do have a person
over here sitting in front of 10,000 lux, which is the
luminosity or flight. It's an actual form of therapy. Where do you have patients
and done a front of light for a period of time which
resembles the light from sun, from the sun and
actual sunlight. The production of serotonin
hormone increases the same way whenever you wake
up in the morning and you go outside for a walk and
it's quite sunny and bright. You feel that uplift in terms of feudal booth
and your emotions. It's because of the
release of serotonin. On the other hand, if the hormone serotonin is
quite depleted, it's, it's pretty increases
the tendency for chronic mental disorders such as depression,
mood, and emotions. Now, lighting can
also have an impact on your mood and emotions. But bright light can promote alertness and
positive emotions. They can look at the
headlights of the car. They're quite bright
and radiating. Whenever you see
headlights of a car, you're quiet alert
while dim light can have a calming effect
and promote relaxation. Like you're walking into
a spot, for example. But light is quiet them to provide an ambiance
of relaxation. Let can also be used to create a specific atmosphere
or mood in space, such as Juan, cosy or
cool and refreshing. All of these ambiances are influenced directly by
the presence of light, of the warmth of the light
as it towards the yellow. Dark yellow, warm yellow, or is it one white,
bright white, daylight? All of these are various
ends of the spectrum. Every single one of the
effects, our productivity, our mental health
and well-being, including our sleep patterns
and our emotions as well. Productivity and performance. The quality of Lighting
and a space can affect our productivity
and performance. Poor lighting can cause eye strain if you're
using computer, for example, iPads, monitors. They do have options nowadays, which is called the blue filter. Blue rays filter, which
blocks blue rays from your eyesight because it's
it's mainly causing ice train. And ice trained as a
result of exposure for a long period of
time to radiation, specifically blue
raised within light. Headaches. Fatigue, and optimal
lighting can also help improve focus
and concentration. This is very important, and
I've experienced this myself. Like one point in time. I changed the lighting
arrangement in my office and then I realized that for some reason I wasn't able
to concentrate at work. I wasn't able to be as
productive as I used to be. Always complained
about the Lighting. There's something
about the Lighting. It's not right somehow. Until I've actually, I've
taken the step and change the bulbs from two
different color schemes. The previous arrangement
was cool white. Then I changed it a certain grade of a yellowish certain
point is warm yellow. Now, for some individuals, warm yellow is more relaxing. For some individuals, warm
white is more relaxing. So you have to
experiment with these. So based on my experiment, I was able to find out
which color scheme of light was best suited for
my productivity levels. Also, which will affect your errors and improves
over all productivity. So light, even though we take it for granted, our
day-to-day life. But it's a very, very powerful tool to
help us become healthy, live a more productive
and prosperous life. Vision and I Health,
this is very important. Afternoon exposing
yourself to radiation, specifically light for
prolonged period of time, it causes ice trains and your muscles get fatigued
and then you have lenses dilation of all
these complications where you need to actually get some glasses to help you correct and rectified such issues. Seasonal affective
disorder, sad, or SIDs, also known
as the winter blues. Often you might have
experienced this. During the winter season, people are quite down. We feel depressed, sluggish,
lacking motivation. Have you ever wondered
why it's due to the lack of light
throughout the day. Lack of exposure to
natural light can contribute to seasonal
affective disorder, which is SATs or sad, a type of depression
that is associated with the winter months when the
daylight hours are shorter. Bright light therapy, which involves exposure to
artificial light. And we can see in the image
over here that mimics natural daylight can help
alleviate the symptoms of sad, lasting than traditional
lighting sources. So if you are going
to take a look at these monthly circumstances, seasonal circumstances
such as the winter season, the lack of lighting creates a certain form of
depression, which is SJD. And in order to
counter effect that, we're going to be
using light therapy, as you can see in
the image over here, to help us pick up the mood and that level of hormones
and our butter bar is due to that change in
lighting scheme within our life. So you understand
the power of light, how it affects your health
and your well-being overall. In general, your entire experience and interaction
with the world, if you think about it, is driven by how you
perceive things. And one key part of the perception formula
is the presence of light
6. Lighting Design Standards governing Interior and Environment Lighting Practices: When it comes to implementing Environment lighting design, like any other
engineering practice, there are governing standards that you need to follow
in order to make sure that your design is
quite applicable and accepted by the norm, by the population or the community which
you are working on. And there are a
governing standards for Lighting Design which shouldn't be followed
depending on your region and your
country of choice. Starting off with the illuminating Engineering
Society of North America, RESNA, it's a handbook actually. Because a comprehensive resource
that provides guidelines and recommendations for
various lighting applications, including indoor and
outdoor lighting. It covers topics such
as illuminance levels, lighting quality, energy efficiency on lighting
calculations. That's a handbook like any
other engineering handbook such as HVAC plumbing Hamburg, they keep can use
it as a resource, as a reference when you are
dealing with applications. For example, if you
have a theater, if you have a retail
store or supermarket, a hospital, all of them, they have different criterias for the required
amount of Lighting. Now within the course,
we're going to teach you various examples. How can you calculate the
lighting requirements for various applications which are drawn from these
various standards. Second of all, you do
have building codes and regulations which are mainly governed by municipalities
and governments, or governing bodies within certain communities
or countries, villages, town, etcetera. These bodies are, let's
say, authoritative nature. They tend to provide the
best practices which are acceptable within the area
that you're working with. Then you do have
the Occupational Safety and Health Administration or a such a regulations which
provide the key guidelines and international scheme
of what is considered to be quite acceptable
for the amount of lighting that individuals can deal with when it comes to occupational spaces such
as working environment. How could you make the
Environment quite safe for individuals and professionals
within office setting? Obviously, if not light is quite to write them. I get fatigue. You got your young
to have complaints of ice trains and glare. So all of these
standards have been experimented based
on best practices recorded for the public and for specialists
who are dealing with projects to use them
as reference to help them come up with proper
Environment Lighting Design. Then you do have retail Learning Standards
which are quite applicable in certain
applications, but not internationally. If you're working in
a mall, for example, that specific retail store
that you're working out, they might have
their own standards, their own best
practices, their own, let's say hacks in terms of how to display certain products, certain way to make them
standard that stands out. Now, are these considered to be official governing standards? No. But there might be
quite selected from these Standards and applied for these specific applications. And you as an employee
or designer working with these companies
are retail stores. You'd expect it to follow these guidelines in terms
of lighting design. And finally, you have energy
efficiency standards. And again, you gotta, you
gotta European bodies, you got American
bodies, you've got dip. Depending on the
country that you're at. There is an energy
efficiency body or a standard that should be followed specialist
to work with. Especially nowadays
the movement is toward sustainability and let's say, maintaining the renewable
and non-renewable resources and becoming
responsible in terms of how do we use
these resources? So these standardized approaches
in terms of efficiency, are going to be part of
your design approach. Let's say if you go
backwards 25 years, for example, this
Standards not exist. You do the lighting
calculations, pick the best option
and that's it. But nowadays, the amount of
energy consumed is important. Even though you do
the calculations, you conduct the calculations, and then you have
a certain option which is quite feasible. Yet, if it's imposes
an environmental, a negative way is going to be
excluded and they're going, you're going to go for option B, which might be more
environment friendly. So these are the
governing standards that you need to keep in mind. Because like any other practice, you cannot just
simply Design random, unexpected things to work. Over the years, many
trials, experiments, experiences from people who have failed have been
documented to help establish those standards and avoid reinventing the wheel. So keep this in mind as you
encounter any project that revolves around Environment,
Lighting Design
7. Lighting Types within the Environment Lighting Design Practice (Type#1): Let's current lecture we're
going to be addressing the two different
types of Lighting. We do have natural light and
we got artificial light. Now starting off with
the natural lighting, we're going to go through the various important
key aspects of natural lightings with
details like I've mentioned, every single point has elaboration of
information next door. It just to help you
understand it better, feel free to pause the lecture, take some notes as
we proceed along. Now, natural lighting,
simply referred to in the first to Lighting from sunlight. When you are having
sunlight exposure, it means natural lighting. There are various important
aspects of natural lighting. First of all, the
health benefits when you are getting
exposed to sunlight, you're going to
be getting a one, a very powerful vitamin, which is responsible
for more than immunity, which is vitamin D. So exposure to natural light has numerous health benefits. It helps you regulate the
body's cardiac rhythm, promotes the production
of vitamin D. It will boost your
mood for sure, enhances overall well-being. These are key important
points including productivity and efficiency
at work as well. Number two, we got
the aesthetic appeal, which is the sense of warmth, freshmen, freshness, and the
depth to interior spaces. Whenever you walk
into a space and you have natural light provides you with and expansion a
sense of expanded space. It enhances the
colors, textures, and the details of the object, making them appear more
vibrant and appealing. This is very important. Energy efficiency, natural
light costs you nothing. You're going to be just simply utilizing natural light without any utility bill at
the end of the month. So utilizing natural light
can reduce the need for artificial lighting
during daylight hours, leading to significant
energy savings. However, there are some
design considerations that will lead to keep in mind. When you are designing for natural lighting in
mind, obviously, you need to keep in mind the
orientation of the building and the sun's
sunrise and sunset. Because the sun rises from the east and sets
off and the worst, you need to make sure that
you have your windows facing those specific areas. Obviously, if you
do have a building, let's say the sun rises
from this direction, and then you're
going to be placing windows on the back and forth. So you're not going to get
any sunlight exposure. You have to be smart about this. And this is usually done at the design stage of any house. For example, the
orientation of the house, the orientation of the building, and the potential for
exposure to sunlight, which will affect the
placement and the sizes of the windows and
relevant openings. Now, the placement of the
openings for sunlight, they will help us shape the
elements such as the shades, and that would
affect our choice in terms of the placement
of the curtains. Now, these design choices can control the amount of light, the direction it
enters the space, and the level of
privacy maintain. You do have curtains, you got Windows, you're
going to have trees, plants. All of these things are going to affect the level
of transparency. Hence will determine the amount of light is going to
be flooding the space. They Lighting strategies. Now, they lighting refers
to the intentional use of natural light to illuminate
interior spaces. You're not going
to be turning off, turning on the lights. On the contrary, when
there's sunrise, you have strategically allocated your Windows,
pictorial curtains, picked whatever openings
that you have with them, the walls of the
space that your ad to allow daylight to pass through the space during the
duration of the daytime. So effective daylight strategies involve optimizing the
Windows placement, utilizing light
effective services, employing all light shuttling, deploying light
shelves or skylights. These are openings in the
ceilings actually that will allow direct sunlight to
flood the space vertically. Integrating shading devices are light diffusers to control the
glare and direct sunlight. You can just simply have, like fenders are basically
let layers which have spaces between them
which allow a certain amount, which allow a certain amount
of light to pass through. And they're quite controllable. You can increase the amount, that can decrease
the amount manually. And you do have the
sustainable design approach. When you are using natural
lighting, obviously, you are maintaining and the responsible use of natural resources
from the Environment, which falls under
sustainability initiative. So incorporating
natural Lighting aligns with the sustainable
design principles, saving the environment,
going green. So if you go towards
natural lighting, it means you are
actually considering the impact of your choices
on the Environment. So this is one type of Lighting which has
natural Lighting, which has the Lighting
from the sun. As simple as that, you get exposure to light
from the Environment, It's up to you as a
lighting designer. Conducting a certain procedure to design your
environment Lighting, to take into account the
orientation of the space, the placement of the
windows, openings, skylights, the daytime
hours, nighttime hours. All of these things are going
to be tools to help you decide how to incorporate natural lighting as
part of your design. Now, in the next lecture, we're going to take a look
at the complete opposite, which is the artificial lighting
8. Lighting Types within the Environment Lighting Design Practice (Type#2): The previous lecture we learned
about natural lighting, which is the Lighting
due to sunlight. Now we're going
to take a look at the artificial lighting and some key important concepts and points related to
artificial lighting. Artificial Lighting
means they use of an alternative lighting
source such as a bulb, a candle, fire, a filament, which we're going to
pass electricity and gets heated up to provide radiation in the form of light as an alternative to daylight. Or it could be used addition
to in addition to daylight to provide excessive or
extra lighting if required. Now here are some key
points to keep in mind when we are addressing
artificial lighting. First of all, we do have lighting fixtures which are
dependent on the placement. Ceiling Lights while Lights, Floor Lamps, we go wild Lights. We do have desk clamps. All of these are various
options of lighting. Fixtures are related or are dependent mainly
on the location. For example, we do
have Floor Lamps, we do have all Lights, Chandeliers, which are
suspended, ceiling Lights. All of these fixtures, we're going to be
tackling them with details and the
upcoming lectures. Lectures, but we're
going to be focusing on the key important aspects
that revolve around artificial lighting
to help you develop a fully rounded understanding of the comparison between the artificial lighting
and the natural light. Then we have the functionality
and task lighting. Based on a specific task, you might be needing
a light source. For example, reading, cooking, a surgery in the hospital, in the library, a retail store. Dependent on the application, we're going to be adjusting
your artificial lighting to reach the end goal
from that application. Ambient and general lighting when you are dealing
with a space, for example, a living room
or at toilet break kitchen. You need lighting
when it's nighttime, if you need to access
the space and this will recall as ambient and
gentlemen Lighting, which consider to be as the primary source of
light within your space. It provides an overall
uniform lighting to ensure basic visibility and orientation whenever you step into a space, obviously it such
as living room, for example, or whenever
you walk into your house, if it's nighttime,
you need to see around to get from one
location to another. And you cannot just
simply wait for daytime to happen to
be able to do so, you need artificial
lighting to be able to maneuver your way
within that space. So examples of ambient lighting include Recessed
Ceiling, the Lights. We've got Track Lighting, Pendant fixtures that spread light evenly throughout a room. Now, what does every single one of the mean and what
does it look like? We're going to be covering
this in the upcoming lectures. There's nothing to worry about. Then we have accent lighting. This is mainly a
feature lighting. You get something that
you need to highlight. You got a car, you got a piece
of Art, you get jewelry, showroom, and you just
simply need to put it on display and put
some spotlights on it. This is the purpose
of accent lighting, the use of artificial lighting in order to highlight Features. Lighting controls, all of the above default under
artificial lighting. But we need to control them. In order to control them, we to have switches,
knobs, diodes, capacitors, which are electrical equipment
that we can use to help us control the amount
of electricity and passing through the
wires which are, which is then
transferred to light. And finally, we have some design considerations
to keep in mind. For example, the
color temperature, which we have talked about. You need a warm tone
or a bright tone. How many Kelvins? The color rendering
index, the CRI, how close is the light source, the artificial light source
to natural lighting? The distribution of
light are going to be covering the entire
area or a small area. All of these things should
be taken into account, such as the energy efficiency as well, undeclared control. So if you have a light source, how efficient is it? Is environment friendly or not? So all of these things, they fall under
artificial lighting. Now, in the upcoming lecture, we're going to focus on
the lighting fixtures, which is the main focus area. At this current point in time, you as someone dealing with
the Lighting Design from a foundational point
of view of terms of the necessities essentials that you should be familiar with. How to use this fixtures, how to pick up their locations. They serve as tools. As a designer, you can have
them to help you come up with the various solutions for
various projects that you're dealing with in terms of Environment Lighting Design
9. Types of Lighting Fixture; Chandeliers: The first type of lighting fixtures we do
have the Chandeliers years. Now. Most probably you've seen
a chandelier in your life, but you haven't given it a second look due to
its abundant nature, it's available everywhere
and every single household, Avila townhouse
are respectively, they have a certain form of a chandelier dangling
from the ceiling, which is used to provide
light within the space. So Chandeliers are considered
one of the light fixtures. If you take a look at
the image over here, this is the zoomed out image
for this current bedroom. We have a chandelier at
the middle of the bedroom. This is the zoomed-in image. Obviously it's suspended
from the ceiling. That's why we call
it a chandelier because you do have a
certain connection, either a chain or rope
or metallic connection, which creates a gap
between the ceiling. The actual light sources. The longer the length
of the chandelier, the closer it is to the ground, the more to the area
you're going to be covering in this current case. Or actually, the higher
the intensity of the light and the brightness you going to be experiencing. Again, the amount
of the area depends on this Decoration
of the Chandeliers. Some of them they
are quite focused. Some of them they
are quite broad. But in terms of
the intensity and the experience of rightness, the closer it gets
to the ground, the more brighter it will feel overlooked someone passing
by under the chandelier. The higher the higher it goes, the more coverage
area they might. You might cover a bigger area, but the lighting
intensity will fade. So the closer you
are to the ground, the more intense is, the further away, the
more it fades but covers a bigger area. Take a look at this
example over here, and it comes into various
Decoration styles. The various designs
have various textures, metallic, glass made,
plastic, whatever it says. The definition or the
classification of a chandelier as a light fixture
which is suspended from the ceiling, give us a mic. It could have multiple bulbs
or it could be a single box. That's not the criteria. That criteria is
located in the ceiling. The ceiling suspended
from the ceiling, and it has architectural
appeal to it of some sort. Comes in various
structured as well, metallic chain based. It couldn't be with a fan
as well much probably you've seen one of
those and villages. So at chandelier is one of the type fixtures that
you can use to help you distribute light
evenly within the space. The great thing
about Chandeliers is the even
distribution of light. That's why they're
always located in the middle or the
center of this space. Because if you do
have a light source, the light consider
like water's going to flow and covered that space. It will cascade downwards. Be higher it goes the
more area at covers, but it's going to be a bit weaker in terms
of the intensity. The lower it gets, the more intensive and it's going to cover a smaller area. So keep that in mind. So the placement of the chandelier at the middle
of the space has a purpose, the even distribution
of Lighting. Now, someone who might
ask what if some of the corners they
don't have light or some areas they don't
have sufficient lighting. What would you do in this case? This is where light layering comes into play stick
look at the image again. Do have Lamps on both sides. And you've got
spotlights over here. So when you turn
on the chandelier, you need extra lighting. You can turn on the spotlights
to cover those dark areas. To take a look at the
Recessed Lighting is for the ceiling lights are concealed or cave Lights there concede Lights within the
perimeters of this face. It couldn't be in the ceiling like the ones we have or here, which will act as supporting light source
to a chandelier. Incase, you do not have
sufficient lighting. That's one aspect. In addition to setting up
at different ambiance, Let's say you turn
off this chandelier. You do have spotlights
over here and you've got the cave Lights over here to
provide a different mood. A cozy app gets,
on the other hand, if it's productive, but it's vibrant and it's
basically active space. We can turn on all of these Lights and people who
are present, for example. And this current living
area will receive a vibe of energy and just simply
brightness and radiation. They're more active. Turn it off one at a time and
you'll notice that it gets dimmer and dimmer
and dimmer it gets, the more relaxed the
ambiance or the atmosphere. So you understand that
this current point in time, what is the chandelier? How could be used in the
process of light layering. Now, in the upcoming
lectures as well, we are going to take a look
at various lighting fixtures. And you'll be able to develop
the awareness of how to combine them together to
help your layer light. And we achieve the goal of creating a proper
environment, Lighting Design
10. Types of Lighting Fixture; Pendant Lights: Now we're going to transition to the second Fixture that we have, which is Pendant Lights. We're going to walk through
the description together. And as we go through
the description, I'm going to indicate a couple of important key points
to keep in mind when you're dealing with
Pendant Lights and how to use them within
the design purpose. So Pendant Lights, they
are suspended from the ceiling by a
cord, chain or rod. Now you might be wondering,
what's the difference between Pendant Lights and Chandeliers. Chandelier is often
the place for the center Lighting a purpose. If you have a space and
living room as US alone, for example, and
you need to read, eat that place at some lighting. The purpose of the sham delirious or simply
to be placed at the center of that space to read the eight
all over the place. That's a different purpose and usually the bigger in size. However, pendants,
Pendant Lights, they can be suspended the
same way as Chandeliers, but they serve a different
purpose that typically consist of a single light source compared to the chandelier, you couldn't have 20th, 30
small bulbs scattered all over that chandelier
enclose an adequate of shade or glass Fixture. Either evasive leg structure or an architectural design
with a bulb inside. For the sake of
decorative purposes. The whole purpose behind
using Pendant Lights, there's just simply to
address your requirements, whether it's task lighting, you have a dusk and you need to add some lighting
to that desk. Instead of having a desk lamp, you could add the Lighting from the ceiling over that does. Or for decorative purposes. If you have, for example, an architectural
piece of work or artwork or a wall
painting for example, you could add some lighting
so it's suspended over it using Pendant Lights
to just simply add that level of ambiance
kind of focal point. Just have your attention go, goes to that specific area that you would like that tension
to be directed towards, whether by guests are
potential visitors or if you're selling a property
for potential buyers. Take a look at the
following image for clarification purposes. On the right-hand side, we do have an example, half at Dining setup. This is a dining table. We do have chairs, we do have a floor mat to zone. That dining arrangement
separated from the entire space. And in order to add
that level of ambiance, to add that sense
of coziness and to have a cohesive look
from the ground-up, we are going to be
adding Pendant Lights. Now take a look at the
arrangement of Pendant bytes. We do have the form
of bubbles, right? We got a form of spheres and every single one of
them is suspended from the ceiling with a
bone inside that sphere, with sufficient spaces,
sufficient spacing between these Pendant
Lights such that it spans over the entire
length of the table. If you zoom out, you're going
to take a look at this. These bulbs, they are spread all over the
size of the table, all over the length
of the table, providing you with a pattern,
a symmetrical outlook. Our brains pick up
on these things. You could have a
different arrangement. For example, you could just
simply have one sender, Pendant light, and that's it. But if it's not sufficient,
you're going to add both of them to help give you
that complete look. So the purpose of Pendant
Lights, think about it. There's a miniature
version of chandelier. It has only one bulb, mainly for the creative purposes
and for specific tasks. For example, you've got a
kitchen, you get a desk. I need to add some Lighting
for that specific area. You could use. Pendant Lights, Chandeliers. On the other hand, they covered the entire zone regardless
of the arrangement. You placed them in
the center and you spread the light all
over that place. So Pendant Lights, they're
more focused in nature, yet they are suspended from the ceiling and a similar
fashion as a chandelier.
11. Types of Lighting Fixture; Ceiling Mounted Fixture: The following Fixture, which
is Ceiling Mounted Fixture, is considered to be one
of my personal favorites. As a designer, it will give
you all of the room and the flexibility to add your
own taste and visualization. Whatever space that you have. Now, these fixtures, they are mountain directly
onto the Ceiling. Think about it as an
add-on or plug-in and provide a general or
ambient lighting for room. They can come in
various designs, such as flush mount. It means the same level as the Ceiling to a certain point. There's no gap
between the Ceiling. Think about my hand
as the ceiling and this is the Ceiling
Mounted Fixture. And the closer you
are to the ceiling, the more flushed it is. On the other hand, you do
have a different option, which you are close to the ceiling or semi
flush mount fixtures, the tank slightly lower
than the ceiling. They are not Pendant Lights, they are not Chandeliers. We have an extended length. There are literally sticking to the ceiling as much as possible. The closer you are, the more flushed it is. Take a look at these
following example. They can look at
this left hand side. You got a huge Mounted Fixture and the Ceiling Mounted Fixture, which acts as a chandelier. It provides you
with the ability to light the entire space perfectly without
lowering the Fixture. Keeping in mind, there's a basic principle here though
we've touched on before. If this is the ceiling
and the lower you go, the more concentrated
the light is, the more focused that is. Think about it this way. If you've got a torchlight, if you bring it
towards your hand, the closer you get to your hand, the more focused as the
light, the further you go, the more spread as the
light and the intensity becomes weaker because
the spread is more, if you're confused about
that port referred to the technical part of the course that we have mentioned at the
beginning of the course, actually regarding
the technical terms with touch bases on that one. So this is Ceiling
Mounted Fixture. This is another example of an architectural Ceiling
Mounted Fixture with a design. It could have Chrome
metallic plating. The Lights could
be a wage and it's cylindrical form ring format. So you can go really crazy with all the ways you
can design a space. Just simply picking lighting, specifically Ceiling
Mounted fixtures. You do have a lot of options. Take your time with selecting the Mounted Fixture because
it's not surprised. It can literally transform the space by having
this Fixture. You're going to transform
it to this Fixture. And you can transform it
to this Fixture as well. Take a look at
their arrangements. They can be for the same space, but every single one of
them has its own ambiance. These two mountain fixtures, the are smaller, but we are spreading them
over that space. So you do have the
option to reduce the size of the Mounted
Fixture, duplicate the amounts, or triple the amount of fixtures based on
your preference, you can go for a centerpiece, a big Ceiling Mounted Fixture
to cover the entire space. Or it can split them
into four similar, smaller sizes, but yet default under
Ceiling Mounted Fixture. Now, this is why this is one of my personal favorites
because I'm the first utility and it's very cheap compared
to a chandelier. If you're going to actually
go buy a chandelier, you should spend a lot of money picking a good chandelier. And the logistics of moving the chandelier because of
the number of flights, the size of the Chandeliers
could be problematic. The Ceiling Mounted
fixtures are more easily, it'll be easier to deal with. You can just simply
mobilize them, put them on a truck, put them
in your car, and that's it. They come into pieces. You can arrange them together. You can do this
single-handedly by yourself, or you could have an
assistant to help you out or simply install
these Lights. Obviously, neither
qualified electrician For sure to add the connections. But what I'm referring
to as the assembly and the logistics of actually getting a Ceiling
Mounted Fixture. It's not complicated at all
compared to a chandelier, but it could provide you
with a similar outcome, even a better outcome because Ceiling Mounted
Fixture and they are more towards modern design. Chandelier is just
simply take a look at previous models of
houses and arrangements. That chandelier to
a certain point and gives you a luxurious look, but slightly archaic, outdated. The modern approach now
for spaces is to have an architectural design
suspended from the ceiling in the form of Ceiling Mounted
Fixture or a Pendant Fixture. Luck we've covered earlier. So at this point we've covered three important
fixtures that you could add to your toolkit as a lighting designer or
an interior designer?
12. Types of Lighting Fixture; Recessed Lights: Transitioning through
the Recessed Lights from the word Recessed, it means these
lights are actually installed and a passion which doesn't appear prominent compared to Pendant Lights, Chandeliers, and Fixture Mounted Fixture, Ceiling
Mounted Fixture. These are prominent. You can just simply print
them out because they're quite sizable and noticeable. However, Recessed
Lights, they are used to deliver a
minimalistic look. Providing lighting
with minimal intrusion from the size of the Fixture. We use the normally
for ambient lights. Think about spotlights,
take a look at this image or
we can use them as a task Lighting for over a certain area like a kitchen
or a desk for example. And the are usually adjusted through the
use of a controller. You can dump them out, increase the brightness or reduce
the light intensity, and then the mountain basically, they can look at the image. This is a basic example
for Recessed Lights. Also, you might find them in
the market as spotlights. Now usually spotless, they
come in different forms. This is an example of
one of these spotlights, but this is electric bass. This is just simply by
a touch of a button. You're able to suspend
this Recessed Lights, just simply click it through the remote control
and you're able to control the actually the
Lighting from this option. But the one that we have over
here as a Recessed light, which is electric based. It has to be
permanently installed. Electric wiring. Take a look at the
zoomed out image. Over. Here we go, 1234567. We got about 88 spotlights. Usually it's, it's preferred to arrange them in
a systematic way. This should be a visual pattern. Obviously, you're not
going to be having random allocation of Recessed
Lights across the ceiling. It's not visually appealing. It shouldn't be back-to-back. Proper spacing between them, ensuring that you're covering the entire lighting
requirements. Now you might be
asking yourself, what are the lighting
requirements? We're going to have that
section of the course. How can you calculate the amount of lighting required
for any space? And based on which
you're going to be able to select the number of pictures to help
you cover that space. There's nothing to worry about. Just keep watching these
lectures, go through the course. And as you transition
towards the course, we're going to get
more hands-on with the calculations behind the
selection of these Lighting. For the time being, we've
added an extra option, extra Fixture that
we can draw on for a minimalistic style, which is we're going to
be using Recessed Lights. They serve mainly the
task lighting purpose, or to create an ambience. You could have a chandelier, you could have Pendant
Lights and around them through the premises or
the perimeter of the space, you couldn't have a number
of Recessed Lights. This is the concept of light layering when you are adding multiple sources
of light together, It's a very powerful tool. As part of lighting design. You turn on the chandelier, you turn on the Recessed light, it will give you an ambulance. Turn off the chandelier. Turn on the Recessed Lights, give you another ambience. The Recessed Lights
and another ambience. Turn the Recessed Lights off, earn on the chandelier. It's on another
ambiance by having these different fixtures
placed a smart fashion, you will be able to change the ambiance and by
changing the amines, you're changing
their atmosphere. And when treating the
atmosphere, It's like living in a complete new environment,
day-in and day-out. So that's the
beauty of Lighting. You're able to transform any space through the
smart usage of Lighting
13. Types of Lighting Fixture; Track Lights: I'm listening to Track
Lights now Track Lights, they consist of a linear track, as we can see in the
image over here, literally just simply a
bar and these lights are attached to it and you're
able to move them along. They offer flexibility
in direct light designed especially for
specific objects or areas. And often this is commercial. This is commercial,
this is used for accent lighting in galleries, retail spaces, or to highlight artwork or
architectural features. Usually if you've
got a car showroom, you've got a restaurant, you gotta museum, you've
got an Art Gallery. You get a furniture store. Often whenever you walk in,
take a look at the ceiling, you might find Track
Lights where you have tracks over certain areas. And these Lights,
they are adjusted to add some focus on the
specific piece of Art, car, piece of furniture,
or whatever it is. The store owners can
be even a purse, that can be even
a pair of shoes, can be a watch, whatever it is. You got the object, you get a real above
it and you've got Lights and these laws
can be adjusted. Now you could use them for home purposes as well if
you take a look over here, but it's not preferred. Why? Because of the
appearance of the whale. If you have living
room, for example, it's not visually appealing
to have a real just simply going across the
ceiling and you've got Lights suspended from it. You could have
different options, get Recessed Lights, you
can use Pendant Lights, You can just simply use
Lamps to help Floor Lights are going to be seeing in
the upcoming lectures. But going for Track Lights is often left for
commercial purposes. Why? Because if we take a
look at any commercial space, usually you find out that
the Ceiling is black. Why just to have those rails
blend in with the Ceiling? It doesn't give you
that visual dilemma. Was like, Okay, what
does that thing which is suspended from the ceiling? So we tend to use Track Lights
for commercial purposes. They give you the
option to maneuver the Lights and change
their orientation. Why Think about it this way every season you've
got new furniture, you can use curves again, you accessories,
watches, whatever it is. So in order to provide you
with the flexibility to accommodate the sizes and orientations for all of these
various and new objects. Iid flexible lighting and Track Lights provide
you with this. If you do have a Pendant
light is going to be problematic and got
Recessed Lights going to be problematic. Why? Because they are fixed. Don't give you the option to move them around,
but Track Lights, they provide you with that commercial flexibility to adjust the orientation and the position of the lighting source
based on your requirements?
14. Types of Lighting Fixture; Sconces: To woulds cones think about Recessed Lights
for the Ceiling. We got Lights for the walls and these are called Waltz cones
in the world has gone. They are mounted on the walls. They provide your functional
and decorative lighting, but mainly the
Kuwait of Lighting. You find them in hotels, you find them in galleries, you find them in mansions across the holes
and the corridors. They come in different styles like a Lamps structure
or you can just simply have
architectural structural plugged into the wall. They are used for
ambient lighting to create a certain ambiance, a certain atmosphere,
atmosphere, a bright atmosphere, task Lighting, for example, if you've got a
desk, a huge office, you could have it
across the walls to create mainly an
atmospheric effect. And this is mainly the purpose. Atmospheric effect,
an animal room. If you get waltz cons,
bedrooms, we're example. And you can have
them in mansions and on the walls of corridors. Or if you have a certain living room that you would like to have
a certain ambiance to it. You could utilize
these waltz cones to help you deliver that park. Think about them as
Recessed Lights, but Recessed Lights are
mainly for ceilings, walls cones are
mainly four walls.
15. Types of Lighting Fixture; Floor Lamps: Floor lamps, floor lamps
are considered to be one of the most versatile and
reachable options, and they are easy to install. Y just simply put them on the
floor and the floor lamps, they are freestanding
lighting can move them from one location to the other
based on your own preference. They have multiple purposes, either ambient lighting
or task lighting, or they come in various designs. You've got torture labs, art clamps, adjustable
reading lamps. All of these are
examples of floor lamps. The whole purpose of
a floor lamp is to irradiate a certain space with a certain
objective in mind. Now, you're not going to use
it for the entire space, but a certain area, for example. And this current
example, we've got a floor lamp as part
of a living room. The whole purpose is
to add some lighting, but primarily we need to add some ambiance because when you are utilizing your living room, it should provide a
sense of comfort. Take a look at this
other example over here. You do have the
edge of the sofa. You got a table with
some greenery on it and obviously got a lot
of space in between them. It would seem like a good
choice to add a floor lamp, which is quite
architectural in nature. It doesn't have to have any point or purpose in terms
of additional lighting. It shouldn't be just simply
for creative purposes. You could have sufficient
lighting in the space, but adding the extra
touch of lighting, controllable floor lamp, it's going to allow
you to change the ambiance and a flexible
way you could turn off all the lights and just
simply turn the lamp on. And you could have a
different ambiance. And if there is no need for
it, take a look at this. It provides you with
a visually pleasing and bizarre architectural
masterpiece. And this is called the Arch floor lamp on this current case, this is primarily
used to provide you with a way or a mean
to locate the base off the floor lamp on the
corner or one side of the space and extend the actual light
source in an arch format. Often in older times, when you have the stand is just the lighting is
somewhere around the stamp. But modern designs, they have proposed
architectural solution, which is an arc. And this arc, we just
simply going to help you have the base of the lamp on one side and extend the source to another point
based on your preference. And that preferences can be
just simply for the sake of ambiance or for a purpose like, such as reading or you're
working on your desk, Think about it this way. You do have the following
so far over here, but you don't want to be
confined by having one of those labs is simply Next
to the sofa all the time. You need to have sufficient
space in-between them, possibly for an additional sofa or a small cushion or a plant. But you have limited
space and you need to have the light over
here maybe for reading, for work, whatever the purposes. So this will give
you an option to locate the base on one side and extend the hanging
light from another side, yet connected in
the form of an art. Floor lamps. They come in different
sizes, styles, number of bulbs, different arrangements,
different lengths. You can have exactly
the same floor lab, about 30 m centimeters
in height, and you get about 1 m in height. They have the same design, but the length is different. So this is the part of
the fixtures that you can experiment with and just
change based on preference. For example, in this
current living room, this current floor
lamp is quite them. Maybe you need to add some
extra vibrance to that space. You're going to have
a brighter light, maybe a longer floor lamp, maybe an arch lamp over here, and just simply read the
eighth over that entire SOPA, for example, options
are unlimited. So at this point you've
added a lot of tools, a lot of fixtures, options that you could drove
from as you are designing, conducting Live Design for any space that
you're dealing with.
16. Types of Lighting Fixture; Table Lamps: Most probably you're familiar
with the basic lamp, which is a table lamp. This is as old as it goes. The whole purpose
of, or the whole, the whole purpose
behind the name is just simply because you
place it on tables. If you've got to Table
counter-top, whatever it is, I need to add a localized light, just simply a small light
on that specific table. You're going to
use a table lamp. They're placed on tables, desks, or surfaces to provide localized Lighting for tasks
or as decorating elements. The purpose from this
table lamp to provide you with a localized
light per person. Let's say you are using a desk, you are doing something
on the kitchen. You could have a lamp Table to help shed some light
on your own task. It's not used for an
overall paste Lighting or simply localized, focused, but as an architectural piece, it could add that, being said, could add that visual appeal
and complement that space. But from a functionality
perspective, it's usually abides by the preference or the
usage of a single person. A single person who's
going to be utilizing this table lamp for that
specific purpose that they have. You're not going to have
dining table and you guys just simply have got one lamp in the middle of
the dining table. Obviously, no one is going to be getting some light
and it doesn't look visually appealing because
it's been wrong replaced. So keep that in mind. If
you have a small desk, you get a table, you got
to countertop or you got to cite table for
example, and living room. I need to add some decoration. I'm lighting ambience. Think about a Table
Lamps because they come in various sizes, shapes, and styles that can
be used for reading, accent lighting, or
creating a cozy amniotes. They are simplistic, accessible, easy to install the provided
with all these options in terms of the architectural
appeal that you would like to implement
within your project or your space on a very,
very small budget.
17. Types of Lighting Fixture; Cabinet Lights: Cabinet Lights. These fixtures are mainly
installed underneath cabinets, which are commonly used
in kitchens primarily, or display cabinets if you're walking into a furniture
store and they got a kitchen kitchen
where they do have these under Cabinet Lights. They provide task Lighting for cooking purposes or chopping vegetables or whatever it is. Anthony light
countertop work areas or objects on display. Again, as part of the kitchen, you could have a small pot
that you would like to place under certain lighting. These under Cabinet Lights, they provide you
with the option, but primarily you find them
in kitchen and nowhere else. You take a look at these
options over here. You've got these cabinets. This is the cupboard. We got the plates. And under that Cabinet, you do have the under
Cabinet Lights. Take a look at this
option as well. This is the kitchen
cabinet and you do have these under
Cabinet Lights, which are similar
to Recessed Lights, if you recall, they
will provide you with the sufficient lighting and
keep the area of work clear. It doesn't seem practical to
have a table lamp over here, or you got a lighting source, or let's say you do have a floor lamp right
next to the Cabinet. It doesn't seem right. It doesn't seem
visually appealing. So to solve that problem, you're going to have
under Cabinet Lights which are built in
inside the kitchen, will allow you to
work comfortably. Have the sufficient Lighting, have the sufficient
clarity of the area without any obstacles
along the way. So under Cabinet Lights usually associate them with
kitchen Practice
18. Types of Lighting Fixture; Cove Lights: Another powerful
Lighting Fixture, which are, which is
the Cove Lights, in this case, Cove
Lighting involves installing lighting fixtures
and Recessed ledgers. What does that mean? If you do have a certain
cavity on the ceiling, take a look at the
image over here. This is the ceiling and
it's slightly drops down with a certain cavity over here and take a
look at the cavity. And similarly over here, you are going to have
the Cove Lights, which a light which is
like a band of lighting that extends over
the interior of that cavity to provide
you with the ambience of a Cove like a cave where you have a
small lighting, dim light. It's not very clear and
not very prominent, but there's a certain level of Lighting. It's a dim light. That's the purpose of a COVID provides ambiance, Lighting, atmospheric lighting
that provides a sense of luxury, uncomfort. In addition to the main Lights that you have as
part of the ceiling. So Cove Lights, they are
often used to create a soft diffused glow
on ceiling or walls. They can look at the ceiling. Over here. You've got an arch and you've
got a small gap over here. And this is we're
going to be installing the Cove Lights to help shed some light over
that specific area. It's very declarative,
very appealing. I provides with a sense of
luxury, keeping in mind, we're going to see in
the Lighting principles and the upcoming lectures, you could lay or Lights. So what I would
suggest, for example, in this current
example over here, you could have the Cove Lights, but you could add
a Ceiling Fixture, certain design to help add additional lighting because of the areas seems quite to them. And they lighting
is not sufficient. Also, you could add some Recessed Lights across
the edges over here. So you do have all the
options that you need to provide you with
the flexibility in terms of changing the ambiance, changing the
atmosphere, changing the level of Lighting
based on comfort. Having one option as part of the ceiling
could be quite limiting. Everyone got different
preferences. Different guests respond
to Lights differently in order to have the ability to control
the level of Lighting. What I would suggest for
you as a designer or somewhat interested on
dealing with lighting design, especially for the
Ceiling, have options. You could have a chandelier. You could have a
Mounted Ceiling Fixture surrounded by a over the edges. It got Recessed
Lights or spotlights. Spotlights. And if you do have
edges or codes, you could have the Cove Lights. Now, you're going to have the controls on one
end of the wall. And these controls are quite distinctive to every
single one of them. You're able to control
the chandelier by itself, the Recessed Lights by itself or the Fixture and
Ceiling Fixture Lights, the Cove Lights, the whatever Fixture that you decide to install and disabling, it will have its own
separate control. And that gives you the ultimate flexibility
in terms of design. If you are working
with your client, for example, your interior
designer and use it, they have certain
lighting requirements, giving them those options of lighting control and
ambiance and pictures. It will help you stand out in
the sense that you provide a luxurious experience and
power over that space. So keep that in mind
as you go ahead and deal with your own projects
in terms of lighting design.
19. Environment Lighting Design Fundamentals as part of Interior Design and Decor: Welcome back to this
section of the course and the previous
sections we'll learn about the various fixtures, the couple of technical terms and principles to keep in mind. Now, let's get to the
part where we actually tried to experiment with the Design by learning
the fundamentals, the essentials, the concepts, before transitioning to
actual calculations, how to, how to calculate the
amount of lighting required for certain space, which is a very powerful
and essential skill that every designer, electrical engineer, Interior Designers
should be equipped with. So starting off with
the key concepts, we're going to be walking
through them one at a time with a couple of insights and
recommendations as we proceed. So Lighting Design Fundamentals, they revolve around a series of Concepts you need to keep in
mind as a lighting designer. First of all, you
need to identify the purpose and the function. Why are you going to
design the Lighting? Are you going to
design the lighting for what is the
purpose of that space? Is that a gym? Is
it a movie theater? Wherever it is? You're going to
start by identifying the purpose and
function of the space. Then determine the specific
tasks and activities that will take place in that area to determine the
lighting requirements. There are standards like we have mentioned which govern
these practices. If you've got an
office, you've got a certain part of the
standard in terms of the lighting requirements
as we are going to see you got to the cafeteria, whatever it is, identify
the main goal first. Then consider the
desired ambience, the moon and the atmosphere that you want to
create and the space. Obviously, if you do
have a movie theater, you're not going to have bright
light all over the place. Keep into account,
taken into account the purpose that you're
going to design the system, for, the Lighting system, for layers of Lighting. And this is very powerful and it requires experimentation, but you need to understand
these different levels of layering that you need to
adopt new in the practice. Use a combination of
lighting layers to create a well-balanced and visually
appealing lighting design. The three main layers are, this is very important
to get three different layers that you
need to keep in mind. You've got the ambient lighting, I think color as the
principal lighting. The primary Lighting,
which provides an overall elimination
to the space. Recap the chandelier
that we've talked about. It can be achieved through overhead fixtures
such as a chandelier, Recessed Lights, or
natural lighting source. Task lighting. This is a
more focused approach, focuses light on specific
work areas or tasks, such as reading, cooking, or working at a desk. Task lighting can be
provided through desk lamps, under Cabinet Lights,
or directed spotlights. Recap the fixtures that
we've talked about. So we've transitioned
from the ambient light, which is the primary
powerful lighting source. Now we're zooming in
to the task lighting. Then we're doing an even
further, the accent lighting, which highlights
specific objects, architectural features, or
artwork within the space. This can be achieved
with Track Lighting, like we mentioned, waltz codices were adjustable spotlights. So you start off by
layering your light. The Sunday principle, principle, light chandelier for example. And then you start zooming in. You start with the chandelier. Everything is quite set up. You'd gotten the Ceiling
Fixture perfectly placed. Now, you've got that
Design covered. Now we need to take into account the various zones that
we're dealing with. We've got a desk over here, we've got a dining
area over here. We got to living room over here. And we need to add those lighting fixtures,
task lighting, accent lighting to help
implement the mood and the design that we have in mind based on the purpose
and the function, you transition to the
light distribution. Consider how light is
distributed within the space, usually in terms of the
height as well at placement, this requires experimentation
to reach the optimal level, aim for even a
uniform lighting to minimize shadows and ensure
equipment visibility. Obviously, if you do have greenery or a plant or
you're not going to have a spotlight in front of it or a lamppost part
of it because you're going to have a huge
shadow on the area. So take these things
into account. Avoid glare and harsh contrast
that can cause ice train. You don't want to be sitting and you're talking to a person, and the light is bouncing off
their face into your eyes, creating glare on a context
which is quite disturbing. Use techniques like diffusers or frosted materials to soften
and distribute the light. Now this is a bit more advanced, but if you do have a bulb, for example, you could have a layer around the
bulb for Table Lamps, which is a glazed glass, which will help break the
patterns of the light, reducing its power,
reducing its impact. And finally, we're going to transition to the
color temperature. This is very powerful, as we're going to see in the
upcoming lectures regarding the Lighting psychology helped impacts your brain and your
motivation and your mood. This is very powerful. Color temperature, so
we're going to select the appropriate color
temperature for the space Color temperature is
measured in Kelvin, which is also used to measure temperature or heat given by the letter K. This is a very
important technical term when you are buying
Lights or bulbs, you're going to find them
on the cover and determines the perceived warmth or
coolness of the light. This is again, very,
very powerful. Usually when you're
buying bulbs, think about it this way. Got two extremes. You've got white light, you get yellow, right? So you got, you go on the
white spectrum and you go on the yellow spectrum
and there are always shades in between. So warmer color
temperature, we go from, when we say warmer, it means yellowish moves
towards the yellow. We have 2,700 Kelvin, all the way to 3,000 Kelvin, which creates a cozy, an intimate asthma atmosphere. While cooler color temperatures, 4,000 Kelvin to 6,500 Kelvin, they produce a crisp and
bright ambience Morley, mainly for productive work. But everyone is different. But we tend to respond to these Lighting
warmth differently. So note them down. We do have a scale, we do have a spectrum for
the warmth of the color. If we are between 2,700
Kelvin and 3,000 Kelvin, we're going to be achieving
cozy and intimate atmosphere, which is often depicted
as yellowish in color, as you can see in
the image over here. These are basically on the warm scale towards
the yellow color. On the other hand, if you have white, cool, crisp light
closer to daylight, we're going to be having
about in the range of 4,000, 6,500 Kelvin can go all the way to 10,000
Kelvin by the way, which produces a crisp
and bright ambience. Thinking about white
light in this case, it provides with
that certain level of productivity
efficiency unfocused. So these are the ranges
of the color temperature. Let's recap these
Design Fundamentals that you need to keep in mind. First of all, identify the
purpose of the function. Layer, the Lighting,
ambient, the principal task, more focused, accent, even more focused than Lighting
distribution. Allocate these Lights properly, then color temperature
because you're going to be selecting the bulbs
for those Fixture. What am I trying to achieve? Is it a productive environment? Is that I'm office is
at a movie theater. Do I have the purpose
or the function to provide a cozy vibe, a cozy ambient, or it's a productive ambiance
and an effective, Let's get things
moving ambience. So I'm going to be picking up the temperature of the light. When I'm heading towards warmth, relaxation and
coziness, I'm going for the yellowish color. If I'm going for something
productive and bright and welcoming and exudes energy, I'm going to go forward the wide spectrum of the
temperature and color. These things you need
to keep in mind as you transitioned further within the course and upcoming lecture, we do have extra fundamentals that we need to keep in mind. We're starting things
off with the basics. We're going to get into
further details before we get to the point where
you are going to calculate literally technically the amount
of light that you need for a certain space before you're able to
apply all of these things. As a designer, as an engineer, or a lighting consultant.
20. Psychology of Lighting Design: I'm back to this section of
the course where we are going to dive into the
psychology of lighting. Now I know you're,
you're now dealing with practical design concepts
for lighting design. But it's important to understand the whole purpose
from the get-go. Why do we care about lighting? How does Lighting
impact our lives? And how does it have all of this influence on our emotions, our cognitive thinking, our productivity levels, our mood. Often these things are quite overlooked by expert Designers, by inhabitants of a space. Most probably be, probably had an experienced buyers by yourself and you have no
idea why this happened. Let me give an example. You walk into a space, all of a sudden you feel blue. Then you've walked
into an another space. You feel energetic. Why? Simply because of
the vibe and the vibe are the ambiance is primarily provided and
controlled by Lighting. So in this current
section of the course, we are going to take a
look at the psychology of lighting and how it
affects our well-being. This will allow
you to understand the importance of Lighting and key considerations
to keep in mind as you are
designing for Project. In this current section,
we are going to transition into the key points. We're going to
highlight the point. Feel free to pause
the lecture and take some notes along the way or
summarizing the concepts. I'm going to walk
you through them. I'm going to add some actually a practical
insights to keep in mind as you go about
your own projects. So when it comes to the
psychology of Lighting, lighting effects our
life and directly, first of all, the
mood and emotions. So Lighting can actually
significantly influenced our mood and emotions where
bright and cool light, we calling the
light temperature, where we go towards the
white spectrum of the light, can promote alertness, focus, and a sense of energy. And often we find
these within offices. Warm, soft lighting,
on the other hand, think about a movie theater, can create a cozy and
relaxed ambience, promoting feelings of
comfort and tranquility. So the color, temperature, the intensity of the light, and the quality of wallet, all of them could contribute
to emotional responses. Bright white light
makes you alert. Provides with a sense of, let's get things going,
will have to be productive. Cozy them light makes
things more relaxed and comfortable in a way where
it reduces your alertness. Circadian rhythms,
our biological clock as humans, as creatures, as connected to the movement and to the rotation
of day and night. Often if you are used to
waking up at a certain time, even before the alarm ticks, you might just simply open
your eyes, I wake up, why? Because your circadian
rhythm hasn't been adjusted certain sleep cycle. So lighting plays a crucial role in regulating our
circadian rhythms, which are the internal
biological processes that regulate our sleep and wake cycle and other bodily functions such
as hormones and your mood. Exposures to natural
light during the day and dimmer warm light in the evening helps maintain a healthy
circadian rhythm, promoting better sleep
and overall well-being. Now let's sight step for a bit from a scientific point
of view in your brain. If you take a look over here, we have a hormone
called melatonin. This hormone is
the sleep hormone. Often people struggling
with insomnia, they are not able to release the hormone or
utilized effectively. This hormone is directly
influenced by light. If you are using your
phone before you sleep, it's often recommended
that you disconnect from light because especially
blue light from devices, it inhibits the
release of melatonin. So if that's done, you're not going
to sleep properly. You're going to delay the time for you to actually
go into deep sleep. So the influence of
light is actually biological as well
and just simply psychological, It's
actually biological. Light reduces the
release of melatonin, our brains, which impacts sleep. And on the other hand, when you wake up in the morning, when sunlight enters your eyes,
melatonin levels plummet. Cortisol hormone
increases, which is a stress hormone to help you
get up and start moving. So light is very powerful. Have you ever tried sleeping M a room which is full of light, obviously going to
be uncomfortable. You're not going to
have quality sleep. On the other hand, it's often recommended
that you sleep in a dark room or minimal
amount of flight, because the presence of light is going to interrupt
your circadian rhythm, perception and visual comfort. If you're watching a movie or you're taking a
look at an object, or you are driving a car
coming in front of you, take a look at the headlights. Definitely that's uncomfortable. Why? Because the light is very
intense, is very strong. It provides a visual discomfort. So lighting affects our
perception of objects and spaces. Well-designed
lighting can enhance the visibility on the clarity of objects, textures, and colors. Think about television. We're taking a look at
the TV, the pixels, some screens are
highly pixelated. Some of them, they have a crisp Image all of this
because of Lighting. It can also minimize
glare, shadows, and visual discomfort, creating more visually comfortable
and Environment. And this applies to
any area of your life. If you wear glasses,
for example, if you do wear glasses often when you put
your glasses on, you tend to see
clearly compared to not having glasses on, right? Why? Because glasses adjust light, productivity and performance. And this is very, very crucial. And I experienced this hands on with comps are
productivity and performance. Now, I'm going to tell, walk you through the
story in terms of my practical experience with productivity
and performance, lighting has a direct impact on our productivity
and performance. Insufficient or poorly designed lighting can lead to ice train. Fatigue, decreased
concentration, and reduce productivity. On the other hand, proper lighting
levels, distribution, color temperature
can improve focus, alertness, overall performance, performance and task
and activities. Now, that being said, let me help you understand this concept which is very crucial, especially if you are working
and working professionally, you've got an office,
you get a desk job. And you're wondering why. Whenever you sit on your desk, your energy levels plummet. You're not motivated to work. You're not concentrating. Most probably it's due to
the lighting that you have. And I've experienced this hands-on because
within my office, I had changed the Lights
from different temperatures, tried to experiment with
various lighting in terms off radiation and efficiency
and effectiveness. However, the bulbs that
I've used where a big week. So the light from
the ceiling was not reaching properly
over the desk such that it provides
you with a sense of an adequate lighting as if it's them and it requires
more Lighting. And I didn't give it
too much thought. But as you're working, you realize it has
a toll on you. You're not able to concentrate. You need to squint your
eyes to see butter, and you need to exude a lot
of energy just to get the job done it due to the lack
of proper Lighting. So what I've done
is I just simply experimented with
different bulbs, stronger bulbs based
on this page that I have because it did not do any calculations at that point. Just simply picking bulbs based
on my own visual insights and my engineering sentence
and picked up those bulbs. And by changing the type of the bulb, the
lighting as well, and incorporating
layering of Lights, Ceiling Lights,
additional lighting. I was able to actually have a more positive experience within the work setting because this light lack of
mentioned we're all creatures and
we are susceptible to the influence
of light in terms of psychology and health. So keep that in mind. Productivity and performance are heavily impacted by Lighting. Transitioning to environmental
and spatial perception. Obviously, when you walk into a dark room, you've
seen nothing. But with proper lighting,
you see everything. An offline. If you walk into one of
those theme parks where you are guided by
trax of Lighting. Light is the key cue
to help guide you. For paths. On paths,
atmosphere and ambiance. And often Designers,
Interior Designers, clients, they focused
on this area. When you are picking up Project. For every area, I
should have a vibe. It should have an ambience. For example, a
living room should provide a welcoming,
comforting vibe. An office space should be
more towards productivity. Lighting plays a
significant role in creating a desired
atmosphere and ambiance. The quality and
the characteristic of light, including color, intensity distribution the
Fixture is the placement can evoke specific
emotional responses and set the tone for space. So Lighting can create a sense of drama, intimacy, vibrancy, and serenity influencing
the overall M means of a room or environment. To think about. When
you walk into a gym. Energy is high. Think about when you
are walking into an office and it should be high. Walking into a movie
theater should be done. Walking into a spot,
more relaxing. It's more cozy for you to have that relaxation
experienced. A lighting is a
crucial component in the practical application. So all of these things should be kept in mind when you are trying to design for a space. You are a lighting designer,
lighting consultant. All of these things
are psychological. Emotions, circadian rhythms, perception and visual comfort, productivity and
performance, Environment as spatial perception,
atmosphere and ambience. So when you have a space, you are a designer, you are a consultant, you are interior designer, but this is the psychology
part behind your practice. They should be using to
help tailor your design. If your client or for
your own preference, you need to design lighting
for a certain room. Understand the purpose. What is the certain ambiance or the comfort that you're trying to achieve
from that space. Are you planning on becoming more productive in that space? Or you need to relax, or simply to have
a cozy atmosphere, a vibrant atmosphere,
serenity and calm. All of these things, they are influenced by the presence of flight
within this space. So keep in mind these
psychological facts as you go about designing
for your own project.
21. Light Layering: Welcome back to the section of the course in which I'm
going to walk you through the key steps that you
need to follow as you go about designing the Lighting for any
space or Environment, we're going to transition
through the sequence of steps with a brief description for every single one of them, have a notepad next to you for some notes as you go along, which will serve you
along the way when you are dealing with
your own projects. Now, starting off with the process that we
need to focus on, which is the layering of
Lighting for different effects. In the previous lectures, we've learned about the types of fixtures that we
have for lighting. We learned about the key
important terminologies as part of lighting design. But in order to
combine these things, in order to utilize them
in the proper fashion, it is important to
keep at the back of our minds the sequence
of steps that we need to follow as we transition towards designing the
Lighting for any environment. Now, at this current stage, we're going to go
through the techniques, strategies, the
sequence of steps. In the upcoming lectures. We're going to go hands-on
in terms of calculations, like clearly
calculate the amount of light just like a fluid. If we get water, for example, how much water is
needed for a building? We're going to calculate
how much light is needed for a space. So these are the concepts that we're going
to be following in the upcoming lectures to definitely keep up
with that as well. Let's kick things off with the
key steps that you need to follow when you are designing
the Lighting for any space. First of all, you need to
establish the ambient lighting. This is the first step. You do have a space
and you need to provide light for the
entire space completely. Often we will go for the
center location of the light, and that light is
going to spread across the entire space covering
the entire area. Let's read the
description together. So ambient lighting, this
is the starting point. We're going to start with ambient lighting as the
base layer to provide overall illumination
and establish the general lightness and brightness for the level
of coordinate space. So you do have a space. Step number one, take
look at the space. Where's the center of
the space Ceiling wise. This would be your
starting point to create the ambient lighting, which is the one responsible for providing the complete amount of light for the entire space. This is your base layer, okay? Now this can be achieved through
Recessed Ceiling Lights. Recap the lecture of
the lighting fixtures, Chandeliers, reassessed
Ceiling Lights. We've got Chandeliers over
here, flush mounted fixtures, which will ensure that the
ambient lighting is evenly distributed to avoid
shadows or dark spots. Now at this current point, we've got two to three
important light fixtures. We've got the
chandelier is we got the Ceiling fixtures which are going to be utilized in addition to the
third Fixture, which is the flush
Mounted Fixture, just simply like a plate, the flushes with a Ceiling. I forgot about it for now
because it's not that much used in the industry, primarily will go for
the chandelier is or the Recessed Ceiling Lights. These are the primary
tools that you need, the primary fixtures that
you need to help you create the ambient
light, the first layer. The ambient light will
cover the entire space, minimizing the presence
of shadows on dark spots. Then we go from
the ambient light, we're going to be
zooming downwards. What do we mean by this? So we start off with the
first layer of light. Think about it like a blanket. We've got the first
layer of light which cascades downwards and
covers your entire space. Then we're going to
narrow things down a bit to be more specialized
and more focused. We will transition to task
lighting within that space. Are there areas you need to
ask yourself that question? Are there areas that need the designated
amount of Lighting, for example, you've got to dusk. It needs light. Fork. You gotta kitchen. It needs like these
light for work. You do have a certain area
for the kids to play with. It needs a specific
amount of light. So these are task-related. Hence we call it task Lighting. Add task lighting
the step number two, to provide focused
illumination for specific activities or
areas. Now we're zooming in. Task lighting can be achieved
through That's clamps. Now recap the lecture of the lighting fixtures
under Cabinet, Lighting for kitchens,
or reading Lights, which could be
also a table lamp. Place the task lighting
sources strategically to provide adequate light for tasks with them creating
glare or shadows. So you start off with
the ambient light. This is your first layer. You zoom-in, identify the areas that need work,
that needs light, specifically for a certain act, which is cooking,
reading, working. That's our task, lighting. This is the second layer Now we're going to
zoom in even further. So you start off with the
ambient light transition to task lighting. That our transition to
the accent lighting incorporate accent lighting to highlight specific objects. So we're not taking a look
at areas within the space, but particular objects,
architectural features. You get some Wall Art for
example, or focal points. You've got a fire
place in the space. You spotlights, Track Lights, or adjustable white Sconces
to draw attention to artwork, sculptures, or other
decorative elements. Accent lighting creates
a visual interests and adds depth to the
overall lighting design. This is the third layer. First layer, ambient
covers the entire space. You zoom in, we go for
the task lighting. We zoom in even further. We got the accent lighting. Now we're going to
tackle with tackle the particular areas within
the boundaries of the space. We've gotten the
wall wash lighting, install world washers or indirect lighting fixtures on the walls to wash the
world's would like. This technique, could create a soft diffused glow and visually expand the
visual expand the space. It can also enhance
the texture of the wall surface and provide a sense of depth and dimension. Now, this step number four, if you need to give specific
attention to your walls, you could add some
lighting at the top of the world is simply to
flush with the walls. It's like a waterfall,
but with Light. You add it to the top of
the wall and just simply the light cascades
downward on the wall. Enough wordless current step. It's targeting walls. So it's part of layering,
but not with them. The space actually on the premises and the
perimeter of the space. Cove lighting
addresses the ceiling. Wall wash lighting takes
care of the walls. Cove Lighting takes
care of the Ceiling. Socks utilize Cove Lighting
by installing fixtures in the edges or recesses to provide indirect
ambient illumination. Cove Lighting could
add warmth for sure. In lighting glow to a room
and create a sense of depth. Now this is particularly
effective and living rooms, bedrooms, or dining areas. So you do have the walls. We're going to go
forward the wall, wall wash lighting to provide
lighting for the world. But often this is
quite aware of the US. We tend to go for
the Cove lighting. The Cove lighting can actually
compensate for both of the world's and the Ceiling
support the Cove Lighting. These are spaces on the
edges of the ceiling. We're going to embed
lighting to give us the diffused effect of
Lighting, Decorating lighting, we've added all of these layers, Started off with the
ambient task and accent the wall,
Washington Cove lighting. Now decorated with lighting, we reimburse specific now, which includes decorate of
lighting elements to serve as visual focal points or to
add the touch-up style. Sometimes you don't have
to even leave them on like a chandelier
at a certain point, which looks
architecturally pleasing, but you don't light
it on just simply for visual display at
personality as well. So this can involve
Pendant Lights with the unique designs or
statement Chandeliers. What do I mean by
stamens Chandeliers? It's a chandelier
that you placed for the sake of Lighting or
the purpose of lighting. But for decorative purposes, just simply look, looks
nice from the ceiling, which enhances the aesthetic
appeal of the room, even when not in use, so forth. The creative lighting is just simply thinking
about it this way. You got a table lamp
which is broken. It has no bulb in it, but it looks nice. It's like an Art and Art work. Just simply display it, put it over there as
a creative piece. Now, finally, the final step for controlling the entire thing as part of light Layering, you're going to go for dimmers. Unlike controls, this is a very important you do have the on and off switch where you
can just simply turn any specific lighting
element on and off. But you do have dimmers as well, which are in the form of diode. This is very important thing. Capacitors, what do they do is they give you
the flexibility to adjust the brightness or dim
the light as you prefer. Instead of having just
two options on and off, you're able to have a knob and
you spin the knob to them, the light or increased
the amount of lead. This is a very powerful in
terms of controlling lighting, energy efficiency, manipulation of the ambiance
and the atmosphere, and creating various
combinations to a fine point. Instead of having two
options on an off, you're able to combine
the intensity of the light layers to get
to optimal ambiances, atmospheres, which
are continuously changing based on
your preference. Hence, you're going to have an environment which
is just dynamic. Instead of having
two options on light Off no light. You could have somewhere in-between a degree of
light that you prefer. So let's recap the
layering of Lights. Think about it this way. It's an inverted pyramid. You start with the first layer, which is the ambient lighting, which covers the entire space, usually a centerpiece
on the ceiling, which here that it's
either Ceiling Fixture or a chandelier mainly. Then you transition
to the second layer, which is more of a
focused approach, which is the task lighting. The task lighting addresses
key locations within the main space that requires specific Lighting
attention such as a desk, a kitchen, a special area
that you need to focus on. Zoom even further
to the third level, which is the accent lighting. Now afford the accent lighting, you highlight specific objects. You got to Wall Art and you add just simply a couple of lights to highlight that wall are. This is an example of accent lighting,
wall wash lighting. Now we're transitioning to the fourth layer where we
take a look at the premises, the parameters of the space, the sides, which are the
walls and the ceiling. Now we'll wash lighting. You could add just
simply Lights which shed some focus on the walls and thinking about
as a waterfall, instead of having water, we're having light,
Cove Lighting. We place them at the
edges of the space Ceiling just to provide us with a diffused lighting sense. Then we'll transition to
the decorative lighting. We've covered all
the basic layers. We've got to be ambient task, the axon, the wall wash
the Cove, lighting. All of the key players, all the key layers are in place. Now we need to add
some decoration to it. The creative lighting
comes in hat. It provides us with two options. Add extra Lighting, F required, add the sense of style and a statement that you
make as a homeowner, as a designer, as a decorator, without the need to use that
piece source of Lighting. Just simply put the
creative purposes. Think about if a lamp
which has a broken bone, but yet the Lamps looks nice, It can use it for display. And finally, to control
all of these layers, we're going to use dimmers
and lighting controls. Think about switches on and off. Dimmers as knobs,
which will help us decrease and increase the lighting intensity
in the space, hence controlling
all of these layers. Now, we're going to reverse the sequence to help you
visualize it better. Your walk into a space. You have two options. Click on chandelier turns off, click off Chandeliers,
turns off. Another button. Click on, you got Cove Lights. Click off the turn them off. Now if I want to combine the chandelier and
the Cove Lights, I'm going to turn both of them all or either one of them on. But if you do have a knob, you could turn both of them on and you can adjust both of them. The chandelier
brightness would go higher and you're going to them, the Cove Lights or
you're going to them the chandelier and increase the intensity and the
strength of the Cove Lights. Both of them will provide you with two different ambiances and atmospheric prints
based on your preference. So these are key important
steps to keep in mind when you are light
designing for any environment, you're going to be
using light Layering. Follow these steps
in order to help you transition from one layer to another and a systematic way. And the upcoming
lectures we're going to have actually hands-on
Calculations. How can you calculate the
amount of light that you need in order to layer
those lighting elements. In addition to the
various aspects that you need to keep in
mind as you're picking up the lighting elements in addition to the lighting
Plans and layouts, whether you are a
lighting engineer, a lighting designer, interior design of lighting consultant. You're able to take a
look of them, read them, and make any adjustments before getting into the execution
of the project phase
22. Lighting Plans and Specifications (Part-1): We've understood the
key important aspects of light layering, but does that mean
we just simply take any space and start installing lights randomly and layering lights
and experimenting. Of course not. There's a sequence of steps that should be followed
as you deal with any project in order to ensure
that you are getting to the end result properly
with minimal iterations, you're not going to
just simply install and decommission and re-install and decommission over
and over again. Every single project has a
budget that has a timeline and there are certain
preferences and key limitations in
terms of standards. So the question is, what
do we need to do in order to properly
have lighting design, environment design
as part of a project and ensure the proper
execution of the project. These are the steps
that you need to follow one at a time. Step number one, first of all, you need to understand
the project requirements. Are you dealing with the product for your own personal use or you have a client that
has certain requirements. Understand what is
needed from the project. I'm going to leave the
description for you to read. It includes sufficient details that help you further
understand the concepts. But I'm going to
go through all of these steps one at a time
and explain them to you. In addition, you can
pause and take a look at the description given
for every single task, every single element to help further reinforce
the concept for you. So understand the
project requirements. First of all, what
is needed from you? What shouldn't be delivered? Are we designing for a house? I would designing for him ball or with his uncle
for a hospital. What is the requirement then? Develop a lighting
design concept. Now based on the requirement, you're going to
develop a concept is an abstract idea of the various lining elements
that you need to be using. How would that look like? Are you are you going
for a certain ambiance? Does the client acquire
a certain ambiance? What is the main objective? So we have certain requirements. We need to deliver certain parts of that requirements based
on a certain preference, whether your preference on the client's
preference determined the lighting fixture types. Often, this comes
through the consensus with the client or if you're dealing with your own project, you're going to
pick the fixtures. Recall the lecture of
the fixture types. We've got the chandelier is we got dependent lights
task lab that's collapsed. All of these are options
and fixtures for every single certain space or empty space that
you're dealing with, you can pick any of those
fixtures to help you deliver the design that you
have and the requirements. So when it comes to
the lighting fixtures, they can look at them. What is the style that
you're going for? What is the budget? What is the preference? Then pick your
fixtures accordingly. Then the lining layer. This is very important.
The first three steps are mainly generic and idea
based or conceptual. Now, the lighting layout, this is where we transition
to the practical part. The lighting your layout
just simply a map drawing. It could be a sketch,
a hand sketch, or an auto CAD drawing like
a professional drafter. You don't have to do all of
these things by yourself. You could have a
lighting engineer or an electrical engineer, or a draft or to actually
draw these drawings for you. Often when you come to deal with interior design and
lighting design, you have to cooperate
with other professionals. It's often quite rare to have a single individual
is able to do all of these things
at the same time. So the lighting layout you
might require to deal with a drafter or an engineer
to help you sketch. And if you're an engineer yourself or a graph to yourself, or you're familiar with using one of the software such as cat, who are able to create a layout. The layout is like a top
view of the space on on that layout and going
to locate that fixtures. I'm going to show
you actually how it looks like in the
upcoming lecture. There's nothing to worry about. For the sake of simplicity and clarity in
terms of the sequence. So the lighting layout is just
simply a plan which shows the locations of those lights that you would
potentially install. Lighting zones and circuits. This is why we tend to deal with the electrical engineering part. Which areas need a
certain amount of flight and what type of
light that will be reflected on your
layout as well. Lighting calculations, I'm going to teach
you how to do this. This is considered to be
the most important part, the most crucial part for successful lighting design
for any environment. What is the amount of light needed that should be delivered? I'm going to walk you
through the steps, how to do the actual
practical example. We get to calculate an
experiment by yourself. And you can apply these concepts and practices to any project that you're dealing
with that will be covered in the
upcoming lectures. Lighting control plan. Where are you going to
be placing the switches? We're going to be
placing the mops. This requires a wiring diagram which goes hand in hand with
the electrical engineer. If your interior
designer and architect, definitely you got an electrical engineer working on the project. You're going to have
a discussion about the locations that
you have decided for the lighting elements
and what does the proposed the wiring from the
electrical engineers site? Create lighting specifications. I'm going to walk you
through this part as well. We'll often when it
comes to creating specs, you don't literally
create the specs, but you pick up the specs from various manufacturers which meets your requirements in terms of the padding
calculations, the type of the fixture, and the lighting layout. So when you have a
lighting layout, Let's say I've decided
to pick a chandelier. I've done my calculations for the amount of lighting required, then I need to pick
the chandelier, right? How would I do this? I need to create specs. The specs would indicate the
image of the chandelier. How does it look like? There's certain requirements in terms of the lighting output, the power consumption,
and all of these details. Often these are already
ready-made in the industry. Any supplier has the specs, it's a matter It's up to you to actually conduct
the calculations. Then have a discussion with the electrical
engineering terms of the power supply for
that specific fixture. Then you're going
to take a look at the specs which
should comply with your calculations
and preferences that document the wiring and
the control details. Again, this is an extra
detail which goes through the power engineering to the lighting engineering, which is beyond the scope
of interior designers. But it's good to know that
your lighting fixtures are not just simply pieces that you place in a space and
forget about them. You have to keep in mind, what are they getting
their power supply from which distribution board is
providing the electricity to? And this goes hand-in-hand with the electrical element as well. Collaborate with professionals. This is very important. Many steps along the way, they do require collaboration
with other professionals. Take a look at this, work closely with
electrical engineers, architects, interior
designers or fewer, you're one of them contractors to ensure that the
learning plans, specs aligned with the
overall project requirements and are feasible to implement. It's a team's effort. When you are dealing with
annual lighting design project. It could be as simple as designing a living
room, for example, you do the calculations
that I'm going to teach you and you just pick up
the elements by herself. That's simplistic. But what I'm talking about
is at a broader scale. Let's say you're designing
for a mall, right? You're designing for hospital. Obviously, this
space is quite huge, requires a team to work
on this in terms of creating the plans that
lay out the calculations, the specification, the
wiring, the controls. It requires a team. So do not expect that you
do everything by yourself. You're going to be
working as part of a team for larger projects. Review and revise. So you've gone through
all of these steps, but mistakes, they do happen. So review, revise. And sometimes when you're doing the calculations
for the lighting, you might notice
that a certain area requires more
fixtures to be added, which in turn will impact
your lighting design layout. Let's say, based on
my calculations, I need a certain chandelier. But I've noticed that I
don't have a chandelier. I got That's clubs
which will not provide me with the lighting
requirements for that space. I'm going to revise my
layout accordingly. So for any lighting design
project that you do have, these are the sequence of
steps or the key milestones. Now we're talking about
project management. So these are the
milestones that you should clearly have listed to help you reach
the end goal of a proper lighting
design project. In the upcoming lectures, I'm going to show you a demo on the lighting layout at them on the specs to help you understand and visualize
where you're dealing with. And finally, we'll transition to the crucial element and the
juice of the current course, which is the lining
design calculations. How can you conduct such
calculations by herself?
23. Lighting Plans and Specifications (Part 2): Welcome back. Now I'm
going to walk you through a demonstration on
a typical lighting. The layout, on the
lighting layouts are going to see various elements. And you should
develop an awareness. What are lighting layouts? How can you read
lighting layouts? And how can you deal and
work on lighting layouts? Now, let's say you're
working on a project. Either you're going to be
handled a lighting layer, or you're going to create
a lighting layouts. Now, starting off with the
smoke call as the plan, this is the Floor Plan
or the just the layout. On the right-hand side, every single drawing
has a legend. Legend includes icons
or elements with certain descriptions that match the visual representation
of that element on the map. What does that mean? Take a look at the
yellow circle over here. It means we have a light
surface which is Mounted. Take a look at the
circle with a cross sign over here we got into
suspended light Pendant. Take up the semicircle. We got black and yellow. It's a wall washer. We got two circles connected. That means we have two
inlets, pen the mountain. We do have to Lights connected
with a bar to light bar. For Lights with a bar, it's afford light bar. We got a bar which is a bit thick and less
current case it through presents a fluorescent
three labs. We got a circle with an asset means a smoke detector alarm. Now, we're going to take these
elements and keep in mind, you're free to create whatever
legend that you desire. It could be whatever colors that you have as long as
you're consistent. So you pick up these elements. Now I'm going to place
them on my plant. Now the plan will
be handed over to me as something which
is completely blank. What I mean by blank. It has the furniture. It has the walls which
are provided in the dark. Straight lines. These represent
lifts, elevators, and you can see the
furniture and the tables. And in this current case, I'm dealing with the restaurant. This is the layout for
a restaurant and they need Lighting Design
for that restaurant. So we deal with the restaurant, we're doing with the
large restaurant. We have a certain requirement to create a certain ambiance. Now, when we were handed over the lighting Plans and we need to conceptualize and pick lighting fixtures and recapping the step that we've
talked about. And then I'm going to transition to do the
calculations if required, and then propose the certain
specs for these elements. Now for the sake of simplicity, we're going to take a look at be Lighting layout and how can we read the
Lighting layout? If you take a look at
this part over here, you do have a table. And in this table we do have
the suspended light pen. So we have a Pendant
over that table. And if you take a look
at all of the tables, all of them, we do
have light pendants, so we understand
that this kind of tables requires light pendens. Now, next are the tables. We do have surfaced month
could be a floor lamp, a fourth floor Floor Lamps. So it just simply located in this current location, right? Take a look at this
part of the huge table. We got two other Lights, which are Panda Mountain. Now, as you go
about the drawings, you might find out that the, the table is quite too long compared to the
amount of lighting. So you might add two of
them or three of them. This is part of the
revision process. So you start placing all of
the elements that you have. Conceptually. From architectural
point of view, aesthetics, how
would it look like? How would you imagine
the space to look like? So you place all of
these elements that you have to create over here, which is a complete
Lighting layout. So we got the bear a plan. It concludes furnitures,
the parameters, the walls that we
have at the doors, which are presented by
these arcs over here. Then we're going to take the legend and move
it all the way to the plant and locate the
lighting elements on that plan. So we've done that part, right? We have done that part. Now. We're going to this
because it to be a draft, we have a layout, it's
an grafted layout. Then we're going to be
proposing certain specs. So I do have a lamp, for example, if you
recap the previous part, let's say I have over here
suspended light Pendant, which is going to be placed
somewhere over here. Then I'm going to go through
check with the suppliers, manufacturers in the market for different options for the bulbs I'm going to install over here. Now, this is the tricky part. You have to keep this in mind. We've got the Lighting specs. These are the specs. So when once we take
any lighting element, it comes in the following sheet, which has the item number
based on the manufacturer. It has the actual image. How does it look like as a
bulb and lighting element? And this Specifications Now the specs are
the energy used. Watts is joules per second
every single second, how much energy is
being consumed? Domestic code,
volts, brightness, average hours, how
long it will work, let's say 25,000 h
before it expires. Life in years. Light appearance,
how many kelvins, which is the temperature,
warm or cool? Beam type beam spread, which is the angle. To recap the lecture on
the technical terms, the color rendering index, how close it is to
the actual wheel, natural light, chromatic C. Then we have efficacy. We got the number of LED modules, minimum
starting temperatures, estimator yearly energy costs, package Type, country of origin. And all of these detailed
are considered to be the Specifications of
this lighting elements. All of them, they are grown
from the technical terms we've talked about
at the beginning of the course regarding
in lighting elements, temperature, power, lumens,
the nature of the light. Is it warm? Is it cool? The physical characteristics, how does it look
like physically? The finish? Warm, white. How sing material? Aluminum. The base G you 5.3, which
is the one over here, which is the metallic grade, then all of these things
are also the rating. If you have damp resistant, it's a UL listed, that means it's fireproof and approved by the fire department. So all of these things are considered to be
the Specifications. Are they written in stone? Of course, not every
single manufacturer has a different list, but there are key elements. Every single Lighting lighting manufacturer would have income, which is the lighting element,
temperature, the wattage, how much energy is
going to be used, the amount of voltage, which is the electricity
going to be consumed, because it, it affects the work of the electrical
engineer as well. And the beam type, the
Lights, temperature, they expectancy of life for
the usage of the element. So these are generic specs
that are going to be found on any project that
you're dealing with once you pick any element. In this applies to all of these, you got the surface Mounted, you can delight found that
it got the world washer. You propose these options,
their potential clients. Or if you're shopping
for your own house, you can just simply take
a look at the bulb, like a typical bulb. Take a look at the back
end of the bulb, the box. But we'll have those details. These are the basic specs
for large-scale projects. You're going to be having
more detailed approach to various elements
are going to install. But here's the tricky part
that I would like to ask you. Are you going to be picking up the specs directly as
you finish your layout? So we've created the layout
with placing the elements. Now I'm going to be
proposing the specs. Well, not just yet. Why? Because I'm going to
conduct calculations first. I'm going to see
how much lighting is needed them that space, based on which I'm
going to propose those elements and those elements and
their Specifications. This is often the missing piece. You do have Designers, they create the layout and
they start proposing specs, the pick elements, and
they start proposing them. Then they do the calculations to find out that these elements, they cannot meet
the requirements. So in order to make sure
things are quite systematic, you create your layout. Then once you're done
creating the layout, you do the lighting
calculations, which I'm going to be
teaching you next. Once you're done with the
lighting calculations, it's up to you to pick
whatever specks that you desire from any manufacturer
across the globe
24. Lighting Design Calculations Sequence: Welcome back to this section of the course where we dive into the calculations needed in
terms of Lighting Design. In the previous sections,
we've taken a look at the Lighting layout,
the Fixture types, the technical terms they
need to keep in mind, but it all comes down to this, how to conduct lighting
Design Calculations. So in order to properly create lighting
Design Calculations, there's a sequence of steps that you should keep at the back of your mind to help
you reach the end goal. First of all, we
need to determine the purpose of the space. Obviously, we need to know what's the space that
we're dealing with. Is that an office
or retail store, a supermarket, irrespectively. Why? Because this will help
us in step number two, which is identify the
illuminance levels. What does it mean the
illuminance levels, the amount of light that should
be given for that space. Now from where do we
get this Standards? Every single country
it has a code, a municipality code, or
Lighting Design Standards, which you can use to help you pick up the
best practices for various spaces in terms
of the requirements for light illuminance by definition, this is very important
to keep in mind, is the amount of light
falling on a surface. And it's typically
measured in foot candles, Fc or lux Lx. Now, for our purposes, we are going to map these to a unit which
is called lumens. Lumens represent the amount of light available from a source. Now, there's nothing
to worry about. I'm going to have
a detailed example for you to actually see how all of these
things fit together. So we need to determine the
recommended or required illuminance levels for the space based on the industry standards, building codes, or
specific guidelines. For example, office
spaces typically require 30 to 50 foot candles, the amount of light
required for offices, we're going to give it
either lux, Candles. Candles are lumens. While retail spaces may
require higher levels, maybe 5,200 foot candles. So based on the application, the purpose of the space, we're going to take a
look at the standard. What is the
recommended amount of illuminance required
for that space, either measured in lux, measured in lumens,
measured in foot candles. But towards the end
of the calculations, you will get to a
value in lumens. Then we're going to convert that value in lumens two watts. We're going to see all
of these things now because you cannot just
simply explain them verbally. These are hands-on calculations. I have a designated
example for you that you can use to help you reinforce
understand the concept. Then consider desk areas. We understand the
importance of the space, but do we have certain areas that require specific attention? For example, you've got a
workstation, you gotta, you gotta desk, opened the Standards, take
a look at them. What is recommended
for the workstation? What is recommended
for the kitchen, what is recommended
for as cinema, a theater wherever it is. These spaces are
going to be detailed, placed with details
in any book or guidelines based on the country
that you're dealing with. You're going to have
a list of the tasks, the areas, and required
levels of illuminance. Then this is where we
transition to the actual part. We've collected the information requirements of the space. And what is the Lighting or the illuminance required
for that space? Now we start calculating stuff. What do we need to
calculate first? Calculate the area of the space, which is the total area of
the space that needs Light, measure or determined
the area of the space. And square feet or square meters for irregularly
shaped spaces, divide them into
smaller zones or calculate the area
separately for each section. You could have one
typical area like a rectangular area and
calculate the entire area. Or if you do have various
shapes to break them down to zones and calculate the area for every single one of them. If you do have
designated areas for certain types of application, you got a workstation here,
you got to get you in here, you get a more with
theater, break them down, and calculate all of
these areas separately, then you're going to select the Learning factors,
for example. This part is not
very complicated, just goes based on preference. For example, the age group of the occupants are the children, are the adults because
these factors are going to influence the
recommended illuminance, which is and step number two, when you take a look
at the standards, it will tell you the area
of the application and the occupants criteria
if they are children. We're going to have a certain
requirement for aluminum. If they are adults,
we're going to have certain levels
of illuminance. These are done based on best practices and failed
projects over the years, which led us to the
best practices in terms of Lighting Design
and preferences based on certain applications. Then this is the part where you are going to conduct
the calculations. I'm going to teach you in the hands-on example, perform
lighting calculations. Use lighting design
software if you prefer, or online calculators you can. Or manual calculations
that I'm going to teach you to
determine the number and the Types of the fixtures required to achieve the
desired illuminance levels. Lighting calculations take into account the lamp efficacy, the Fixture efficiency,
maintenance factors. Okay, so all of these things
are what follows next, you are going to design
your Lighting system. You are going to conduct
the Calculations. You are going to
pick your fixtures, and then the maintenance part
and all of these aspects that come later on if you are dealing with a more
complicated project, this is the end goal. We need to determine
the lumens needed. So after performing the
lighting calculations, we got to a certain point. We know what's the area. We need to identify the amount of Lighting
to be provided in that area following these
manual calculations or these softwares,
how can I do this? Once again, I'm going to show it through a detailed example. So you need to determine
the lumens needed, convert the required
illuminance. Go back to this step. Step number two, you identify
the illuminance levels from the Standards which are measured
in foot candles or lux. We're going to convert the foot candles or
lux into lumens, which measured the total amount of visible light emitted
by light source. Lumens designated
by the letter L, M indicate the light output
of a bulb or Fixture. Refer to the lighting
manufacturer specs or consult lighting Design Standards
to determine the lumens needed to achieve that this
diode luminous levels. So step number seven goes hand in hand with
step number two. For step number seven, we need to convert
the amount of lumens, the amount of foot candles
or lugs to lumens, which are drawn
from the standards. So you have the Standards, you've defined the space, you pick up the
requirements in terms of the foot candles or the lux for that space,
which is the illuminance. We're going to convert
this to lumens. And these lumens are
going to be used for the selection of our fixtures. This is step number eight. After you determine the lumens, you're going to be selecting the fixtures and the quantity of those fixtures that
will provide you all of the lighting
requirements for your space. Then you validate
and you adjust. Often you do the calculations, you find out that
certain number of fixtures is over
occupying the space. You need to downgrade the number of the fixtures and
increase the size. For example, if you have Ceiling fixtures and
you've got Chandeliers, if you're Ceiling has to
Ceiling fixtures that might seem too crowded
than you'd drop it down and have a single
chandelier instead, which might provide the
lighting requirements fully. So all of these adjustments are done after the Calculations. Now I'm sure at this
current point in time, you might be a bit confused in terms of how does
this thing work? Well, it's easier
than it sounds, but I'm going to Week up
all of these steps for you because these steps are
exactly the sequence that goes at the back of the mind
of any lighting designer or interior designer
conducting Calculations for any Lighting Design Project. In the upcoming lecture, I'm going to have a worked
example for you that you can actually implements
one step at a time. Then once you revert
to this lecture, you able to recap how all of these things fit together
so afford the time being. Let's go through
the steps together. Step number one,
determined the purpose. Then identify the
amount of illuminance, lighting requirements, either end foot candles or
lux from this Standards. Then if you do have
special attention for the area based on the
standards like the occupants, adjust the number from the
illuminance accordingly, calculate the area of the space, the Lighting factors such as the maintenance and all of these standardly
come later on. Don't give it too much
thought at the time being. Conduct the lighting
calculations where we need to get the amount of light through either software
manual calculations or any online calculators that
you can use if preferred. But we're going to go for
the manual approach in order to get the number
of lumens needed. So we get the lux, we get the foot candles, we do the calculations to get to an end goal, which is lumens. Now, the lumens are
going to be the ones responsible for the
selection of the fixtures. Why? Because we have calculated the amount of light
for the entire space. Now let's take a look at the fixtures based
on their specs, which will provide me with
the sufficient lighting, then I'm going to confirm my Design and
adjusted accordingly. This current point in time, you have the detailed sequence of steps at the
back of your mind. It's time to transition to a hands-on example where
we tie everything together
25. Lighting Design Calculations Example: Welcome back to this section
of the course in which we have our worked example. Number one, we might be
adding extra examples. So make sure that you stay tuned for all of these
practical problems which will help
you fight you and your understanding
of the concept. So let's dive into our example
where we take what we have learned in the
previous lecture and map it to real-life application. So a worked example number one, we do have an office
space application. We need to calculate the amount
of lighting required for a typical office space is the
area given to us is 93 m². And those 93 m², take a look at the
image over here, 93 m². They include workstations,
which are 75% of the area, and meeting rooms, which means the rest is 25% of the areas. So we get the total
area of 93 m². 75% of that includes
workstations, 25% meeting room, if you recall
from the previous steps, identify the project
and then we'll take a look at the areas
within that project. Now, step number one, I'm going to map the previous steps to this current example
for you to help, to help you understand how the steps that we dealt
with in the previous lecture, they map to the
real-life practice. So determined the
purpose of the space. Step number one, the office
space is going to be used for general work
activities such as reading, writing, computer
work, and meetings. What is the point of this? We're going to go
to step number two, which is the Standards, the illuminance levels
from those standards. According to the industry
standards, alpha spaces, they typically require
illuminance level of 30 to 50 foot candles
or 300 to 500 lux. Any standard has
both of these units, either foot candles or lux. Based on the application
which is office space. Take a look at the country code, or the municipality code, or the international
lighting standards that we've covered in
the previous lectures. Going to find out that
for our application, which is an office space, we're going to have
a requirement of 30 to 50 foot candles
or 300 to 500 lux. Now, we're going to consider the areas
with them, that space. So we're going to identify the specific task areas
within the office space, such as the workstations and the meeting rooms that may require higher lighting levels. For this example, we'll assume a desired
illuminance level of 50 foot candles for
the workstations and 30 foot candles for
the meeting groups. Now, we have identified
the entire space, but within that space there are certain areas which require
specific attention. Workstations and
the meeting rooms. So we're going to assume
for the workstations, 50 foot candles, and
for the meeting rooms, 30 foot candles instead of going for because we have
the range over here, 30 to 50 for the
entire office, right? That's 30-50. So we're
going to pick 50 for the for the workstations
and 34 the meeting rooms. Instead of just simply picking
one value for all of them. Then we're going to calculate
the area of those spaces. Now, the office space has a
total area of 1,000 sq ft, which is about 93 m². The area we have is 93 m². This is the total
area of our space. Keep that step in mind. Then we're going to take a
look at the Lighting factors that we chose to ignore
in the previous lecture. Because literally in terms
of the real-life practice, we take the average
room lift reflectance, typical occupant age group. We don't consider any
additional changes which might be imposed
by the standards. But if you have a delicate application like
a medical room or desktop, refer to the
standards which HIV, which have factors that
you need to multiply, whether your results to help
make those adjustments. But for the sake of simplicity, we're going to assume
the average room has an average reflectance, light bouncing off the surface, which is quite average.
Typical age group. And we won't consider
any factors beyond us. Then we're going to conduct
the hands-on calculations, which is step number six. So since our spaces on
office, we have two parts. We got the workstations and
we get the meeting rooms. We're going to deal with
the workstations first. So the workstation lighting
calculations, first of all, we have set the desired
illuminance level to be 50 foot candles or 538 lakhs, which is about 500 lux. Than the area of
the workstation, is going to be 75%, like we haven't mentioned
at the beginning of the total area. So 75%, which is
0.75 times 1,000, will give me 750 sq ft. We
have 1,000 sq ft times 0.75. You can use also at the square meters,
that's perfectly fine. Area is 93 m². We can just simply
change this value, 0.75 times 93 m² We're interchanging
both of them. Feet and meters is going
to be perfectly okay. There's simply units. So 0.75 times 1,000 sq ft
equals to 750 sq ft. Now, lumens needed to poured
the workstations, the amount of lumens. This is the step that
we need to get to. We're doing everything to get the amount of light
for that space. So the lumens needed for the workstations equals
to the workstation area, which is 750 sq ft, times that desired
illuminance levels, which has 50-foot capitals. So the area times
the foot candles will give you the
lumens 750 sq ft. Make sure that you keep
these things in mind. Square feet times foot
candles will give you lumens. So 750 sq ft times
50 foot candles. So the area in square feet
times the illuminance and foot candles together
will give me the lumens. So we have 37,500 lm
for the workstations, which comprise 75%
of our total area. We've done with
the workstations. Let's apply the same thing
to the meeting room. So we transition to
the meeting room. That desired illuminance
is 30-foot Candles. Now you understand the sequence of steps just simply repetitive, is just a sequence
that we follow up for any design application. The area of the
meeting room equals to 25% of the total area, which is 0.25 times 1,000 sq ft. We got the area
for our meeting rooms, which is two 50 sq ft. Now we need to
multiply them with the foot candles to get lumens. So the lumens needed for the
mirroring rooms equals to the meeting room area times the desired
illuminance level. 2f0 square feet times 30 foot candles will
give me 7,500 lm. So we've got the
lumens requirement for the workstations and
the meeting rooms. The final step determined the lumens needed for
the entire space. So the total lumens needed for the opera space is the sum of the lumens calculated for the workstations plus
the meeting room. So the total lighting
requirements, like I've mentioned, this is the main End goal we need
to get to this point. What is the amount of flight
needed to flood that space? So the total lumens needed
equals the lumens board, the workstations plus lumens
board the meeting rooms. For any other application, just simply add all of
these stations together, all of these zones to get
the total lumens needed. And our current example, we have 37,500 lm plus 7,500
lm equals to 45,000 lm. So how do we get the lumens? Like I've mentioned, the
area in square feet times two times the foot
candles give you, gives you the unit of lumens. Now, we've calculated
the major milestone, the amount of lumens
needed for our space. At this current point in time, we start to explore the
fixtures which will provide me with the sliding based on my requirements
are my preference. Shall I go for Pendant Lights? Shall I go for Chandeliers? Shall I go for desk
lamps, whatever it is, that will help me
reach my end goal of 45,000 lm to provide the adequate lighting
for the office space. Now, there's a very
important side note that to keep in mind, we have a term which
is the efficacy. Efficacy refers
to the connection between light and electricity. So when we have lumens, the amount of light is coming
from electricity, correct? Now, efficacy represents
or connects watts, which is a measure of
electrical energy consumption, in this case, joules
per second or watts, and the amount of lumens. For example, if you
do have a bulb, this bulb will have an
efficacy level which indicates that for every
one watt electric supply, get a certain number of lumens. And this will help you create the conversion between lumens, which has light to
electricity that's going to be used by the
electrical engineer. And you as the world
when you're picking up these items and the specs
of those items as well. So how does that look like? Of course, we're going
to see this together. So select the lighting fixtures based on the calculated lumens. Select lighting fixtures that by the required Lighting output, that's clamps Ceiling
light wherever it is. For example, if LED panel to
panel above the light above the workstations or
the office spaces to just a panel
provides a light, has an efficacy of
100 lm per watt. So every single one of
electricity that is given to that Lighting
panel will give you 100 lm. You would need fixtures
with a total water. Why are we converting
from lumens to watch? We're going from lumens two
watts because when you are buying the actual pieces
of light fixtures, specs are designated
on both terms, lumens and was often
electrical engineers. They are not dealing
with the lumens. And as a lighting designer, interior designer,
they understand that, but they need that
wattage term to help create the bridge between
electricity and light. So we're going to convert
the lumens two watts. So in this current case, the total amount of wattage equals to the total
lumens needed, which is 45,000, divided
by the Fixture efficacy. And this current case, it's given to us that B
Fixture that we have, which is a Lighting panel
place on the ceiling, has an efficacy of hundred
lumens per watt every one. What gives you 100 lm? So we have 45,000 lm. How many watts do we need? You can either go for the
cross multiplication to find the relation between the or just simply follow the
formula I've placed for you. For the sake of convenience. Total wattage equals to total Lumens needed divided
by the Fixture efficacy. And this current
case, we have 45,000 lm divided by 100 lm per watt. We have 450 watts. So our space is going to be flooded with 45,000
lm worth of flight, which is equivalent
to 450 watts worth of electricity going to
those lighting fixtures to give me that amount of light. So at this current
point in time, I will be able to go to the
market and start taking a look at the Lamps, the panels. If I do have a desk lamps, what is the amount of watts
for every single Fixture? What is the amount of lumens provided for every
single Fixture? And I'm going to get them. And towards the end, I'm going to revise my
calculation and take a look at the number of fixtures that
I've placed on my layout. Do they add up to the
total requirement of 45,000 lm and 450 Watts, such that I've provided the adequate Lighting
for my space, and I've selected the
fixtures which will help me meet those requirements. So make sure that this current
point in time that you replay the current
example as we go, as we have one through the
steps that we've covered in the previous lecture and appropriate and
sufficient detail. We have taken the approach
for the generic layout of the steps and we
have mapped them to this current hands-on example, which is a real-life project
you can use as a reference. Now in the upcoming lectures, we will have further examples
for you to further apply the concepts and reinforce
your understanding
