As used in this chapter:
(a) "Aiming Angle" when applied to exterior lighting, this term is correctly used only with directional lighting systems. In this case, the aiming angle is the angle between the center of the object or area being lighted and the point on the ground directlybeneath the luminaire.
(b) "Exterior Lighting System" means an installation of lamps, luminaires, electrical wiring, controls and mounting hardware (such as poles or brackets) designed to illuminate outdoor areas, landscape or buildings.
(c) "Floodlight" means a type of directional luminaire or lamp which may be adjusted on site to project and direct light out and away from the mounting location. Floodlights are typically designed to illuminate relatively large areas.
(d) "Fluorescent Light Source" means a low pressure gas discharge lamp in the form of a bulb or tube which utilizes a phosphor as the light-emitting element.
(e) "Full Cut-off Luminaire" means a type of fixed directional outdoor luminaire which emits no light above a horizontal plane through the optical center of the luminaire or, alternatively, above an angle of ninety (90) degrees where zero (0) degrees is the aim point on the ground directly beneath the luminaire.
(f) "Fully Shielded Luminaire" means a luminaire equipped with opaque hoods, louvers or visors so as to completely block the light from going in other than a specified direction.
(g) "Glare" means the visual sensation produced by brightness in the field of view that is sufficiently greater than the light level to which the eyes are adapted so as to cause annoyance, discomfort or loss of visibility.
(h) "Halogen Light Source" means an incandescent lamp with a halogen gas filling typically designed to increase energy efficiency and lengthen lamp life compared to standard incandescent lamps.
(i) "HID Light Source" means a lamp which utilizes a small gas arc discharge or "high intensity discharge" as the light emitter. Examples of HID light sources are mercury, metal halide and high pressure sodium lamps.
(j) "Incandescent Light Source" means a lamp containing a tungsten wire filament heated to a high temperature as the light-emitting element.
(k) "Lamp" means a bulb, globe, tube or capsule, usually formed out of glass, containing an electrical and physical assembly of materials designed to convert electricity into light.
(l) "Light Pollution" means wasted light directed into the sky which results in sky glow and the loss of the natural beauty and visibility of the sky and stars.
(m) "Light Source" means the light emitting portion (filament, arc tube or element) of a lamp.
(n) "Light Trespass" means outdoor lighting which emits unwanted light or glare beyond the boundaries of the property on which it is located.
(o) "Lumen" means the unit measure of light flux or light output from lamps and luminaires.
(p) "Luminaire" means a complete lighting unit typically consisting of all electrical and mechanical parts necessary for operation including a lamp, ballast (in the case of discharge lamps), optical assembly and enclosure.
(q) "Luminaire Mounting Height" means the vertical distance between the ground and the optical center of the luminaire in an outdoor lighting system.
(r) "Optical Center of Luminaire" means the point inside of a luminaire at the middle of the light emitting area of the light source.
(s) "Recreational Lighting" means lighting of ball fields, courts, pools, playgrounds, and/or other outdoor sports, play, or recreational areas other than those accessory to single family residences.
