For the purposes of this ordinance "lumens"denotes initial <br /> lumens for HID lightin�a.pplications. <br /> Luminaire means an individual li ting assemb including t�e lamp and any housings reflectors globes <br /> lenses, shields or other components desi�ned to block or distribute li�ht. For the�urposes of this <br /> ordinance, an internally illuminated sign is not considered a luminaire. <br /> Luminance means a measure of the bri�ttness of a surface which is emit#in�ght. The unit of <br /> measurement most commonly used is candelas per square meter often refened to as nits in the USA(1 <br /> nit= 1 cd/m21. The nocturnal appearance and environmenta.l effect of objects such as intemall lv it signs <br /> mav be analvzed both by total li t out�ut(lumensl and bv their surface bri�,htness(nits). <br /> Luminance Meter means: A speciat instrument that directly measuces Iuminance. <br /> Luminous Flux means the power emitted from a source of electromagnetic radiation such as a light bulb, <br /> in the form of visible light. Lumi�nous flux is measured in lumens(or lux and is typically�ecified bx <br /> the manufacturer for a�iven lamp or luminaire. Typical luminous flux values for incandescent bulbs are <br /> 140W: 15501umens 75�V: 1080 lurnens 60W: 7801umens and 40W 4501umens. <br /> Motion Activated Sensor means a sensor which causes a luminaire to become illuminated autamaticallv <br /> upon the presence of motion or infrared radiation or a combination thereof within its field of view <br /> Motor Fuel Stations means any buildin�or premises used for dispensing or offering for sa.le automotive <br /> fluids or oils,having,pumps and under�,rowad storage tanks; also,where batterv,tire and other similar <br /> services are rendereci,but only if rendered whollv witivn a building. <br /> Motor Fuel um in Area means the drivable surface of an automobile service station in the immediate <br /> vicinity of a fuelpump,where vehicles are narked durin�elin� <br /> Nadir means tbe direction pointiz� d� irectly downward from the li�ht source of the luminaire that <br /> originates from a horizontal plane at the lowest point on the luminaire. <br /> Neon Light means brightly colored light�enerated by using electric cunent to excite a gas or gas mixture <br /> f includin�neon, ar�on,helium, or other�)typicallv contained in a tube which can be bent into <br /> various forms for use as decoration or siqas For the purposes of this ardinance fluorescent tubes are not <br /> considered neon light. <br /> Nits are a unit of ineasure of luminance(see lumina.nce� <br /> Page 6 of 7 <br />
