234 Kelvin means a unit increment of temnerature and is used as a color temperature scale of a li ng t bulb <br /> 235 �svmbol "K"), <br /> 236 <br /> 237 Lamp means the source of li ng t being emitted from a luminaire, such as a bulb. <br /> 238 <br /> 239 Landscape Li�htinQ means outdoor li�htin�directed at trees, shrubs,plants, flower beds fountains <br /> 240 gardens, and other natural or landscaped features. <br /> 241 <br /> 242 LiQht means electromagnetic radiation within a range of wavelengths sufficient for visual perception by <br /> 243 the normal unaided human eve. <br /> 244 � <br /> 245 LiQht Level means the illuminance as measured in accordance with the practices contained in the IESNA <br /> 246 Lighting Handbook,Eight Edition. <br /> 247 <br /> 248 Li�htinQ Installation means an arrangement of one or more luminaires includin anv mounting hardware <br /> 249 brackets, and supportin�structures. <br /> 250 <br /> 251 Lumen: A unit of ineasure of luminous flux. For the purposes of this ordinance, "lumens"denotes initial <br /> 252 lumens for HID li hting applications. <br /> 253 <br /> 254 Luminaire means an individual li hting assemblv including the lamp and any housings reflectors lo�bes <br /> 255 lenses, shields or other components designed to block or distribute light. For the_purposes of this <br /> 256 ordinance, an internally illuminated sign is not considered a luminaire. <br /> 257 <br /> 258 Luminance means a measure of the bri�htness of a surface which is emittin��ht. The unit of <br /> 259 measurement most commonly used is candelas per square meter, often referred to as nits in the USA(1 <br /> 260 nit= 1 cd/m2). The nocturnal appearance and environmental effect of objects such as internallv lit signs <br /> 261 mav be analvzed both by total li ng t output(lumens) and bv their surface bri�htness (nits). <br /> 262 <br /> 263 Luminance Meter means: A svecial instrument that directiv measures luminance. <br /> 264 � <br /> 265 Luminous Flux means the power emitted from a source of electromagnetic radiation such as a light bulb <br /> 266 in the form of visible li�ht. Luminous flux is measured in lumens (or lux and is t icall�pecified by <br /> 267 the manufacturer for a�iven lamp or luminaire. Typical luminous flux values for incandescent bulbs are <br /> 268 100W: 15501umens, 75W: 1080 lumens. 60W: 7801umens, and 40W: 4501umens. <br /> 269 <br /> 270 Motion-Activated Sensor means a sensor which causes a luminaire to become illuminated automaticallv <br /> 271 upon the presence of motion or infrared radiation or a combination thereof within its field of view. <br /> 272 <br /> 273 Motor Fuel Stations means anv buildin�or premises used for dispensin�or offering for sale automotive <br /> 274 fluids or oils,havin�pumps and under�round storage tanks; also, where batterv.tire, and other similar <br /> 275 services are rendered, but onlv if rendered wholly within a building. <br /> 276 <br /> 277 Motor Fuel pumping Area means the drivable surface of an automobile service station, in the immediate <br /> 278 vicinity of a fuel pump, where vehicles are parked during fueling <br /> 279 <br /> 280 Nadir means the direction pointin directly downward from the li�ht source of the luminaire that <br /> 281 ori�inates from a horizontal plane at the lowest point on the luminaire. <br /> 282 <br /> 283 Neon Li�ht means bri h�tiv colored li h�t�enerated b�usin�electric current to excite a a�s or gas mixture <br /> 284 (includin�neon, ar�on, helium, or other ases tvnically contained in a tube which can be bent into <br /> Page6of7 <br />
