What kind of conditions do LED street lamps need to qualify for LED street lights?

- Apr 29, 2019-


 1. The conversion rate of light is 17%, (1000W per square meter of solar energy, the actual utilization efficiency is 170W)


2. At present, the street lamp lens material is an improved optical material with a transmittance of ≥93% and a temperature resistance of -38-+90 degrees.


3.LED street light lens, mainly used for LED street light lens, the spot is rectangular, the material is PMMA optical material, the transmittance is ≥93%, the temperature is -38-+90 degree, the anti-UV ultraviolet light yellowing rate is 30,000 hours. Change, etc.


4. The average illuminance of the uniformity of road surface illuminance is 0.48. Spot ratio 1:2


5. Meet the road illumination. (The actual 1/2 center spot reaches 25 LUX, the 1/4 center light intensity reaches 15 LUX, the lowest light intensity of 4 lux at 16 meters, and the overlapping light intensity is about 6 LUX.


6. It has very good application prospects in new urban lighting. Dimming of depth, and color and other characteristics do not change due to dimming.


7. Adapt to humidity: ≤95.
