2. ◦ Definition of 'lighting fixture' a lighting fixture is
part of a light that is attached to the wall or
ceiling where you put the light bulb or other
lighting element, and which cannot be easily
removed.
◦ Fixtures may also have a switch to control the
light, either attached to the lamp body or
attached to the power cable. Permanent light
fixtures, such as dining room chandeliers, may
have no switch on the fixture itself, but rely on a
wall switch.
◦ Fixtures require an electrical connection to a
power source, typically AC mains power, but some
run on battery power for camping or emergency
lights. Permanent lighting fixtures are directly
wired. Movable lamps have a plug and cord that
plugs into a wall socket.

The three most common forms of architectural lighting
are cove, soffit and valance; all three are integrated into
the room’s structure. Cove lighting is located in a ledge,
shelf or recess high up on a wall, and the light is
bounced toward the ceiling or upper wall. Soffit lighting
is located in a soffit or cornice near the ceiling, and the
light radiates downward, washing the wall with light.
◦ Valance lighting is located in a wood, metal or glass
valance (horizontal shield) mounted above a window
or high on the wall, and the light bounces both
upward and downward.
◦ The technique of bouncing light off walls and ceilings
is known as indirect lighting, which is favored by many
lighting professionals because indirect lighting
minimizes shadows and glare. Architectural lighting is
most often used as ambient lighting

4. Ceiling-Mounted Lighting Fixtures
◦ This broad range of fixtures is, as its name implies, mounted directly to the
ceiling, and typically features a glass, fabric, or plastic shade that conceals the
light bulb and helps diffuse light more evenly.
◦ Ceiling-mounted fixtures tend to be used to provide ambient light in a room as
opposed to accent or task lighting because they provide more general,
dispersed lighting.
Recessed lighting fixtures.
◦ Installed above the ceiling, this type of lighting has an opening that is flush with
the ceiling.
◦ A recessed light requires at least 6 inches of clearance above the ceiling, and
insulation is essential to ensure that condensation does not drip into the fixture.
◦ Recessed lighting sends a relatively narrow band of light in one direction; it can
be used to provide ambient, task or accent lighting
Pendants lighting fixture.
◦ Pendant lights are lights that hang from a cable, cord, or pipe from an
attachment at a ceiling, ending in a shade enclosing a light bulb that primarily
provides light in a downward direction, known as a down light. Pendants are
often located over a table or kitchen island because they provide ambient or task
lighting, and usually have strong stylistic elements that bring character to a
space because they’re so visible.

5. Cornice Lighting
◦ Cornice lighting, also known as soffit
lighting, directs light down from
behind a soffit or cornice, washing the
wall with light. The light source or light
fixture is shielded by a panel parallel to
the wall and attached to the ceiling.
Cove Light
◦ In cove lighting, lights are often
directed towards the ceiling or the top
of the walls of a room. The lighting
may be concealed behind valances,
above crown moldings, or built into
ledges or recesses, but essentially the
lighting is indirect. Cove lighting has
the potential to breathe new life into a
dull room.

6. Factors to Consider when
Planning a Lighting System
◦ 1. The amount of light required for an area will depend on various factors
like:
◦ Location and direction of the light sources.
◦ Reflected qualities of color.
◦ Textures used in the room.
◦ The number of lamps and fixtures.
◦ The wattage of bulbs and tubes.
◦ 2. If artificially lighting a room check on heat gains.
◦ 3. Design and durability.
◦ 4. Ease of replacement especially if lampshades are used.
◦ 5. Cleaning-they should be easily cleaned.
◦ 6. Cost.

7. Recommended Value of Illumination
◦ General Labs- 400 Lux Reading Tables- 600 Lux
◦ Bars- 50-70 Lux
◦ Kitchens- 200 Lux
◦ Restaurant Tables- 100 Lux
◦ Bedroom- 100 Lux Hospital Wards- 50 Lux
◦ Stairs and Corridors- 100 Lux

8. Principles of Lighting Designs
The use of lighting is visually pleasing when it follows the following principles:
1. Balance: This is achieved by placing light sources throughout the room avoiding a
concentration of light on any side or area of the space. Balance can be symmetrical or
asymmetrical.
2. Unity: This can be achieved by duplicating the fixtures as well as repeating the
materials, finishes, colors, textures, and maybe lampshades.
3. Variety: Variety can also be created by having general and local lighting also by
changing the level of illumination with dimmers.
4. Emphasis: It is given by highlighting. Lack of emphasis in an interior causes
boredom, confusion, and uncertainty as to the design content and intention.
5. Rhythm: The sequence of lighting will create a luminous rhythm giving the space a
dynamic quality.
6. Scale and Proportion: The fixtures must be in proportion and scale to the room,
themselves, and to the relative objects in the room.
7. Harmony: If the contrast between general and accent lighting is too strong there
will not be enough luminous transaction and the lighting composition will lack
harmony.
