illumination. They can direct light upward, downward, or in all
directions.

A

Scones

19
Q

Are used in high-ceiling areas, 20 ft (6 m) or higher that require
uniform illumination.

A

High Bay Luminaires

20

Are more compact. They are designed for use in low- to
medium-ceiling areas, 12 to 20 ft (3 to 6 m). They are typically
used for general illumination in offices, retail spaces, and
loading dock areas.

A

Low Bay Luminaires

21
Q

Is a luminaire that is designed to emit an intense, concentrated
beam of light with usually no more than a 20° divergence
(spread) from where it is directed.

A

Spotlight

22
Q

A luminaire that emits an intense light that is broader than a spotlight
and that is capable of being pointed in any direction.

A

Floodlight

23
Q

Is illumination where light received at the work plane or
light illuminating an object is incident predominantly
from a particular direction.

A

Directional Lighting

24
Q

A directional lighting installation where luminaires are
attached to and are moveable along a metal track.

A

Track Lighting

25
Q

Is a lighting installation in which the light on the working
plane or on an object is not incident predominantly from
a particular direction.

A

Diffused Lighting

26
Q

Is a lighting component such as a translucent glass refractor
that redirects or scatters the light from a source.

A

Diffuser

27
Q

A lighting installation where the light source is shielded
by a panel that is parallel to the wall and attached to the
ceiling; it distributes light over the wall.

A

32
Q

 Fluorescent luminaires canHave parabolic-shaped reflectors and open louvers to direct
the light downward.

A

 Parabolic Louvered

33
Q

Fluorescent luminaires can Have a lens that wraps around the lamps to diffuse and direct
the light outward.

A

Wraparound

34
Q

small, offer low maintenance, and have
excellent light and color qualities

Halogen and Compact fluorescent lamps

35
Q

Good color rendering, 2 qualities and work
well in spaces with high ceiling.

A

Metal Halide Lamp

36
Q

Used when color rendition is not important
such as factories and warehouse.

A

High Pressure Sodium (HPS) Lamps

37
Q

Are rarely used in building interiors
because they produce a monochromatic
yellow light that renders even the most
vibrant colors in the shade of yellow.

Elliptical Reflector (ER) Lamp

40
Q

That may use and incandescent filament, halogen
filament tube, or HID arc tube, is a pressed-glass reflector
lamp. Relay on both internal reflector and prism in the lens
for the control of the light beam

A

Parabolic Aluminized Reflector (PAR) Lamp

41
Q

Is an advance lighting technology that transports light from a single source over a
distance to one or more light outlets emits light evenly along the way.

A

REMOTE-SOURCE LIGHTING INSTALLATIONS

42
Q

is a set of reflectors, filters, and lenses to
fed the light of fiber optic cables and a fixture to distribute the light at the
point of illumination.
