21
Q

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

A

22
Q

ꟷ 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

ꟷ is illumination where light received at
the work plane or light illuminating
an object is incident predominantly
from a particular direction. The only
light that is important is the light that
falls where it is needed. ______, _______,
and _______ lighting are common types
of directional lighting.

A

Directional Lighting, spot, flood, task

24
Q

a directional lighting installation where
luminaires are attached to and are moveable
along a ___________. A more subtle method of
directional lighting involves the use of one of
the many different _________ downlights.

A

Track lighting, metal track, recessed

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.
______________ is cast
and disbursed over a large area.

A

Diffused lighting

26
Q

is a lighting component such as a
translucent glass _________ that redirects
or scatters the light from a source. This
type of lighting can be produced by a
variety of _________ lighting techniques,
where much of the light reaches the work
plane after it has reflected off another
surface such as a wall or ceiling. Diffused
lighting is frequently used to provide soft,
background lighting.

A

Diffuser, refractor, indirect,

27
Q

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

source is shielded by a ledge or recess with
light dispersed over the ceiling and upper
wall.

A

Cove lighting

29
Q

ꟷ a lighting installation where the light source is
shielded by a panel that is parallel to the wall
at the top of a window

A

Valance lighting

30
Q

widely used for general lighting installations in buildings.

A

Fluorescent lighting

31
Q

________________ are available in recessed, surfacemounted,
or pendent style fixture designs. Unlike the concentrated
light emitted by other commercially available light
sources, fluorescent lamps produce a ________________ that is
relatively glare free and visually comfortable. As a result, they have been and continue to be the standard for ambient illumination for classroom and office lighting installations.

A

Metal halide lamp

40
Q

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

A

High Pressure Sodium (HPS) Lamps –

41
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

A

Low Pressure Sodium (LPS)
Lamps

Discharge (HID)

43
Q

Hazardous Location such as paint
spray booths, flammable chemical areas,
refinement plants and corrosive area has a
specific type of luminaries approve for this
area. The agency such as Underwriters
Laboratory, Inc. (UL), tests and lists the
approve fixtures for a specific types of use.
_________6 fixtures and lamps are also
required when a luminaire will be used in
installations involving extreme
temperatures.

A

Hazardous Areas, special

44
Q

Are incandescent, compact fluorescent or HID lamps with a built-in reflecting surface. HID and Incandescent versions are made from a single piece of bowl-molded soft or hard glass. Compact fluorescent versions may be one piece or designed so that the inner lamp can be replace.

A

45
Q

Incandescent lamp with an elliptically shaped reflector.
Particularly effective at increasing efficiency of baffleddown

Elliptical Reflector (ER) Lamp

46
Q

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

A

Parabolic Aluminized Reflector (PAR)
Lamp

47
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. It is more costly than
traditional lighting installations. Use in decorations and
gives healthy and safety benefits it releases less ultraviolet
energy and infrared. However, RSL is less energy efficient
than conventional systems

A

REMOTE-SOURCE LIGHTING INSTALLATIONS

48
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. The number of fixtures
depends on the intensity of the light
source.

A

Fiber optic RSL systems-

49
Q

a
