As used in this chapter, the following terms shall have the
meanings indicated:
DIRECT LIGHT
Light emitted directly from the lamp, off of the reflector
or reflector diffuser, or through the refractor or diffuser lens,
of a luminaire.
FIXTURE
The assembly that houses the lamp or lamps and can include
all or some of the following parts: a housing, a mounting bracket
or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or
a refractor or lens.
FLOOD OR SPOTLIGHT
Any light fixture or lamp that incorporates a reflector or
a refractor to concentrate the light output into a directed beam in
a particular direction.
FULLY SHIELDED AND FULL CUT-OFF LIGHTS
Outdoor light fixtures shielded and constructed so that no
light rays are emitted by the installed fixture at angles above the
horizontal plane as certified by a photometric test report.
GLARE
Light emitting from a luminaire with an intensity that is
great enough to reduce a viewer's ability to see, and in extreme
cases, causing momentary blindness.
GRANDFATHERED LUMINAIRES
Luminaires not conforming to these codes that were in place
at the time this code was voted into effect. When a local law "grandfathers"
a luminaire, it means that such already-existing outdoor lighting
does not need to be changed unless a specified period is specified
for adherence to the code.
HEIGHT OF LUMINAIRE
The height of a luminaire shall be the vertical distance
from the ground directly below the center line of the luminaire to
the lowest direct-light-emitting part of the luminaire.
INDIRECT LIGHT
Direct light that has been reflected or has scattered off
of other surfaces.
LAMP
The component of a luminaire that produces the actual light.
LIGHT COLOR
The use of warmer color lights is to be used. Limit the amount
of shorter wavelength (blue-violet) light.
LIGHT CONTROL
The use of controls such as timers and motion detectors to
ensure light is available only when needed, dimmed when possible,
and turned off when not needed.
LIGHT INTENSITY
The intensity of the light shall be the lowest intensity
required.
LIGHT TRESPASS
The shining of light produced by a luminaire beyond the boundaries
of the property on which it is located.
LUMEN
A unit of luminous flux. One footcandle is one lumen per
square foot. For the purposes of this chapter, the lumen-output values
shall be the initial lumen output ratings of a lamp.
LUMINAIRE
This is a complete lighting system and includes a lamp or
lamps and a fixture.
OUTDOOR LIGHTING
The nighttime illumination of an outside area or object by
any man-made device located outdoors that produces light by any means.
TEMPORARY OUTDOOR LIGHTING
The specific illumination of an outside area or object by
any man-made device located outdoors that produces light by any means
for a period of less than seven days.
A schedule of examples of acceptable and unacceptable lighting
fixtures is annexed to this Chapter.
