FORMS OF ARCHITECTURAL LIGHTING Flashcards
Good ________________ is crucial to the performance of everyday activities and to the appreciation of the built environment.
architectural lighting
Sometimes called
“general lighting”
Ambient lighting
Provides uniform
illumination
throughout the space
• Illumination for color
and texture.
Ambient lighting
Sometimes called “task lighting”
• Illumination provided for specific
visual function
• Can influence the effectiveness of
the individual performing the task
Local lighting
Light source that adds a quality of interest to the space
• Combines with other types of lighting to give an overall
“feel” to a room that serves little purpose other than to
look attractive
Decorative lighting
Is directional lighting used to emphasize
a particular object or area
• Emphasizing a particular architectural
feature, piece of artwork, photograph, or
plant
Accent lighting
Is a secondary lighting system that provides _____________ when
the power supply to the normal lighting system is interrupted.
Emergency and safety lighting , backup illumination
• Required in the critical
care and emergency
spaces found in
hospitals, police, fire
protections and crisis
management areas.
Emergency lighting
Enables _____ activities to continue substantially
unchanged.
• Powered by an emergency generator or battery backup
system
Stand-by lighting, normal
Ensures the safety
of people involved
in a potentially
hazardous process
Safety lighting
To ensure that an escape
route can be effectively
identified and used in
case of failure of normal
lighting system
Escape lighting
Illuminated signage used
to provide clear directions
for an emergency exit of
building occupants
Exit lighting
a luminaire that is hang with a _____, ______, or
_______ that enables it to be suspended from a
ceiling or other support. It broadcasts light over
the entire space.
Pendent, chord, chain, tube
is a luminaire where a _______ light source
directs its light to the ceiling, where it is
________ back to the space.
Uplight, shielded, reflected
a luminaire that is usually attached to or
__________ in the ceiling and emits a
___________ light downward
Downlight, recessed, concentrated
a type of downlight that is a recessed, ________-shaped
luminaire with a shielded lamp that emits light downward
High Hat, canister
are mounted above the ceiling or behind a wall or
other surface so that any visible projection of light
is ___________.
Recessed luminaries, insignificant
a decorative, wall-mounted luminaires that
provide _______ illumination. They can direct light
upward, downward, or in all directions.
SconeS, ambient
are used in high-ceiling areas, 20 ft (6 m) or
higher, that require uniform illumination. ____________
fixtures installed in a _____ pattern are typically used
to provide ambient illumination in warehouses,
gymnasiums, and retail superstores. These
luminaires are high wattage (200 W or more) so
they can deliver light over long distances. The
fixture size is fairly large, about 2 ft (0.6 m) for a
typical fixture.
High Bay Luminaires, high bay, grid
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. Both
high bay and ____________________ can be used in
up lighting and downlighting applications.
Low bay luminaries x2
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.
Spotlight, intense, concentrated
ꟷ a luminaire that emits an
intense light that is broader
than a spotlight and that is
capable of being pointed in
any direction.
Floodlight
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.
Directional Lighting, spot, flood, task
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.
Track lighting, metal track, recessed
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.
Diffused lighting
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.
Diffuser, refractor, indirect,
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.
Cornice lighting, parallel
an uplighting installation where the light
source is shielded by a ledge or recess with
light dispersed over the ceiling and upper
wall.
Cove lighting
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
Valance lighting
widely used for general lighting installations in buildings.
Fluorescent lighting
________________ 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.
Fluorescent luminaries, diffuse light
have a flat lens to diffuse the light.
Lensed
have parabolicshaped
reflectors
and open louvers
to direct the light
downward.
Parabolic louvered
have a lens that
wraps around the
lamps to diffuse
and direct the
light outward.
Wraparound
A _________ is a linear luminaire constructed of an inverted METAL TROUGH that serves as a fixture for fluorescent lighting lamps. It is usually installed with theopening flush with the ceiling.
troffer
Fluorescent luminaires can be
incorporated in a _____________ that is
constructed of open fluorescent luminaires
mounted above a translucent ________
ceiling. They can also be used in a _______
installation consisting of rows of bare-bone
fixtures with exposed lamps.
luminous ceiling, suspended, strip
Offer excellent lighting and solutions to specific lighting problems.
New Lamp and Luminaire designs
small, offer low maintenance,
and have excellent light and color
qualities.
Halogen and Compact fluorescent
lamps –
good color rendering
qualities and work well in spaces with high
ceiling.
Metal halide lamp
used when color rendition is not important
such as factories and warehouse.
High Pressure Sodium (HPS) Lamps –
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
Low Pressure Sodium (LPS)
Lamps
produce
a very intense light, a direct view of the
lamp can be extremely irritating. Even with
diffusion globes or lenses, the light can be
very intense.
Incandescent, Halogen, and Highintensity
Discharge (HID)
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.
Hazardous Areas, special
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.
REFLECTOR LAMPS
Incandescent lamp with an elliptically shaped reflector.
Particularly effective at increasing efficiency of baffleddown
lights.
Elliptical Reflector (ER) Lamp
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.
Parabolic Aluminized Reflector (PAR)
Lamp
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
REMOTE-SOURCE LIGHTING INSTALLATIONS
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.
Fiber optic RSL systems-
a
hollow tube with a reflective inner
surface that directs light through
the tube. The most common
linings are prismatic films and
mirrored surface.
Light pipe RSL systems-
