What is standard of LED street lamp renovation
LED street lamp standard is commonly: 1. Light conversion rate 17%, Each square solar power is 1000 w, the actual efficiency of 170 w) 2. Current market street lamp lens materials for the improvement of optical materials, through the rate of 93% or higher heat resistance - 38 - + 90 degrees. 3. LED street lamp lens, the
the LED street lamp standard is commonly: 1. Light conversion rate 17%, Each square solar power is 1000 w, the actual efficiency of 170 w) 2. Current market street lamp lens materials for the improvement of optical materials, through the rate of 93% or higher heat resistance - 38 - + 90 degrees. 3. LED street lamp lens, lens is mainly used for the LED street lamp, spot for rectangular, material is PMMA optical material, through the rate of 93% or higher heat resistance - 38 - + 90 degrees, resistance to UV ultraviolet ` yellow rate for 30000 hours without change, such as LED street light, 4. The road illumination uniformity, uniformityofroadsurfaceilluminance) The average illuminance on the 0. 48. Spot ratio 1:2 5. In accordance with road illumination. （ Actual 1/2 center spot of 25 lux, 1/4 center intensity 15 lux, 16 meters minimum 4 lux light intensity, the overlapping intensity 6 lux. 6. It has very good application prospect in the new urban lighting. The depth of the dimming, and the color will not change by the dimmer and other characteristics. 7. To adapt to the humidity: 95% or less of 8. Quality guarantee: 2 years despite the LED street light rapid development speed, but the LED street lamp and the standard lag. Globally, the LED street lamp standard is not all have no, as a European standard now has LED lights. In fact, regional standards of LED street lamp, on the index is not the same, we do LED lights to accord with the requirement of sales areas in the standard, so bid LED street lamp project to study the local standard of LED street light, only in this way will dominate induced crack of market competition.
