6. LIGHTING DESIGN
“Lighting plays a vital role in the quality of our daily lives. At work in offices, production or logistical facilities, good
lighting brings employee satisfaction, performance, comfort and safety. In shops, galleries and public places, it
creates ambience and helps to accentuates the architectural environment. “

7. • Light is a creative medium, the most powerful of all. Most of what we know of our world comes to us through our eyes, and
the way we see things depends on how they are lighted.
• Light plays a central role in the design of a visual environment: the architecture, people and objects are all made visible by the
light.
• Light influence our well-being, the aesthetic effect and the mood of the room or area.
Light is that part of the electromagnetic spectrum that is perceived by our eyes.

INTRODUCTION-LIGHT

8. • It is the light that first enables ”what we see”.
 Light defines zones and boundaries.
 Light expands and accentuates rooms.
 Light create links and delineates one area from another .
WHY WE REQUIRE A LIGHT

9. • Lighting has several functions. These are:
 Illumination: The simple ability to see what is occurring on. Any lighting design will be ineffective if the viewers cannot see the
characters, unless this is the explicit intent.
 Revelation of form: Altering the perception of shapes on space, particularly three- dimensional elements.
 Focus: Directing the public attention to an area of the region or distracting them from another.
 Contrast: Lighting of an object or area so that it becomes brighter than its surroundings.
 Functionality: The level of illumination required for a particular application depends greatly upon seeing the task involved
and upon the surrounding conditions.

WHY WE REQUIRE A LIGHT

10. TYPES OF LIGHTING

11. • There are two types of lighting
1. Natural Lighting
2. Artificial Lightin g
TYPES OF LIGHTING
NATURAL LIGHTING ARTIFICIAL LIGHTING

12. • NATURAL LIGHTING
Daylight (using windows, skylights, or light shelves) is sometimes
used as the main source of light during daytime in buildings. This can
save energy in place of using artificial lighting, which represents a
major component of energy consumption in buildings. Proper
lighting can enhance task performance, improve the appearance of
an area, or have positive psychological effects on occupants.
• Importance of Day lighting
The two primary reasons for using daylight to meet the illumination
requirements of an architectural space are the psychological benefits
and the energy savings benefits. Good daylighting has been shown to
improve the overall attitude, satisfaction and well being of building
occupants. A number of research studies, a few of which are listed
below, have shown a variety of benefits of daylighting in different
building types and functions, among them improved retail sales in
big box stores, increased worker productivity and reduced
absenteeism in office buildings, improved student educational
performance in K–12 schools, and improved patient recovery times
in hospitals. Exposure to daylight has also been shown to improve
general health and circadian rhythm. These psychological benefits
can easily justify any extra design effort or added expense associated
with introducing controlled daylight into buildings.

TYPES OF LIGHTING

13. • ARTIFICIAL LIGHTING
Artificial light sources are light sources which
artificially combine just the necessary
components of the optical spectrum. The way in
which these components are combined
determines the color rendering of the light
source and thereby affects the way in which
objects appear when illuminated with the light
source
.
Artificial light can be created by combining red (R),
green (G) and blue (B) components
Changes in the RGB ratios change the characteristics
of the light and therefore the mixture ratios of RGB
fluorescent substances is an important point to be
taken into consideration when creating artificial
lights

CFL BULBS HALOGEN BULBS
SODIOUM BULBS LED BULBS

14. METHODS OF LIGHTING

15. GENERAL LIGHTING
General lighting is the main source of illumination in a space. This uniform, base level of
lighting can easily become the focus of energy reduction, as the light levels from other
fixtures can be lowered, especially when using LED and CMH lamp sources.
Recommended light levels for general lighting is 30 – 50 foot-candles
TASK LIGHTING
Task lighting is used to illuminate an area for a specific task; providing a focused,
localized, and higher level of illumination. Necessary to the functioning of a space, it is
important to use
energy efficient sources to reduce operating costs. Task lighting is most effective when
used as a supplement to general lighting in workspaces, conference areas and on
counter tops. Effective task lighting should eliminate shadows on the specific
illuminated area, while preventing glare from the lamp or off surfaces. Recommended
light levels for task areas are 50 – 200 foot-candles.
ACCENT LIGHTING
Accent lighting creates a dramatic emphasis on the space using a focused, or point, light
source or sources. It adds depth, contrast and creates a focal point for items to be
displayed; it highlights shape, texture, finish and colour. If this light is directed
ambiguously, the end result may have many unwanted shadows obstructing the details
of the highlighted items as
well as distracting glare. The key is to make this illumination more precise and of higher
intensity than the surrounding ambient light. Track fixtures, recessed housings with
adjustable trims and concealed adjustable illumination with point source lamps provide
directional control and are especially effective for accent lighting. Recommended light
levels for accent lighting are
between 150 – 500 footcandles

16. LIGHTING QUALITIES

17. The colour rendering index (CRI) Sometimes called rendition index, is a quantitative measure of the ability of a light source to
reproduce the colour of various objects faithfully in comparison with an ideal or natural light source.
Colour rendering: Effect of an illuminate on the colour appearance of objects by conscious or subconscious comparison with their
colour appearance under a reference illuminate.
A palette of specific colors is used, and the CRI calculation is the difference between each color sample illuminated by the test
light source and the reference source. The group of samples is averaged, and a score between 0 and 100 is calculated, with 100
being the best match between light sources. The higher the CRI of a light source, the better – and more natural – colors appear.

19. LIGHTING LUMINAIRES AND THEIR TYPES

20. LUMINAIRE
There are basically two types of luminaries:
•Stationary
•Movable
DIFFERENT LIGHT LUMINARIES ARE:
Downlights
Uplights
Spotlights
Tracklights
Pendants
Free standing
Washers
sconces

21. DOWNLIGHTS
Down lighting is most common, with fixtures on or recessed in the ceiling casting light
downward. This tends to be the most used method, used in both offices and homes.
Although it is easy to design it has dramatic problems with glare and excess energy
consumption due to large number of fittings.

22. UPLIGHTS
Often used to bounce indirect light off the ceiling and back down. It is commonly used in
lighting applications that require minimal glare and uniform general luminance levels. Up
lighting (indirect) uses a diffuse surface to reflect light in a space and can minimize disabling
glare on computer displays and other dark glossy surfaces. It gives a more uniform
presentation of the light output in operation. However indirect lighting is completely reliant
upon the reflectance value of the surface. While indirect lighting can create a diffused and
shadow free light effect it can be regarded as an uneconomical lighting principle.

23. PENDANTS
These lights are good choices for dining areas. They come in different finished and
styles. They are very functional allowing people to see clearly what they are doing. They
can add function and elegance to an otherwise busy area.

24. WASHERS
Most of what one actually sees, entering a room, are the vertical surfaces. The illumination
requires asymmetric lighting fixtures, which, in a number of 3 or more in a line, can produce
evenly illuminated walls. It is a tool mainly used by lighting designers
, to create lighter spaces or making the rooms seem brighter or higher. Wallwashing is a
popular name for a lighting design technique for illumination of large surfaces. It is mainly
used with contemporary architecture; in public cultural buildings, museums and galleries;
and in landscape lighting.

25. SPOTLIGHTS
A lamp projecting a narrow, intense beam of light directly on to a place or person,
especially a performer on stage.
A strong, focused light thrown upon a particular spot, as on a small area of a stage or in
a television studio, for making some object, person, or group especially conspicuous.

26. WALL SCONCES
A sconce is a type of light fixture affixed to a wall in such a way that it uses only the wall
for support, and the light is usually directed upwards, but not always. It does not have a
base on the ground.
Sconces can be placed on both the interior and exterior walls of buildings.

27. TRACKLIGHTS
It is one of the best lighting alternatives out there, it is a good solution for areas that
are hard to illuminate or add lighting to. The system comes with individual lamps or
lighting heads that fit into tracks which can be secured to the ceiling. There are
different choices in shapes and lamp sizes: they can be good for modern contemporary
and transitional designs. Track lighting is a method of lighting where light fixtures are
attached anywhere on a continuous track device which contains electrical conductors.

28. FREE STAND LAMPS
It is used for mood lighting, the table lamps are best used in bedrooms and in the
corner of the living room. They are available in various sizes, shapes and design.
