LED technical requirement of street lamp 100W
(5) the environmental temperature of LED street lamp should be -20 to +50 centigrade, and other special requirements such as temperature, humidity and corrosiveness of the local environment should be satisfied.(6) the power factor is greater than or equal to LED 0.95 lamps, lamp power supply efficiency is more than 95%.(7) the working voltage range of LED street lamp is from 85V to 265V (in this voltage range, LED lamps can still work normally).(8) LED street lamp has surge suppression performance (against lightning stroke), the input over-voltage protection, when the voltage is restored to normal, can resume work.
1) for LED lamp with heat radiating type aluminum lamps, good heat dissipation performance.(2) Aluminum Alloy shell is made of high quality material, light body surface spray treatment, the surface should be able to withstand the mechanical stress and salt fog, car exhaust, and cleaning agent corrosion etc..(3) LED street lamp shell protection grade: IP65 above.(4) good bat wing light distribution design, reflector system adopts stereo light source or lens light guide design, lens must use non imaging two times optical lens, in order to ensure the brightness and uniformity of the road surface, increase the radiation range.
LED light source technical requirements:(1) LED light source chip requires the use of internationally renowned brands (American CREE CREE, German OSRAM Osram and Holland PHILPS Philips), and uses low thermal resistance, good heat dissipation and low stress packaging technology.(2) using high luminous efficiency LED chip. LED chip luminous efficiency more than 110Lm/w, no ghosting, low light attenuation.(3) LED light source color temperature 4000K-6000K.(4) LED light source life: no less than 50000h.(5) the general color rendering index LED lamp: Ra = 75, the road evenness in more than 0.4.(6) LED street light 10000 hours less than 8%, the service life of 50 thousand hours, 50 thousand hours less than 30%.
