Currently, LED lighting technology becomes more and more mature. The light effect of high-power LED has reached 80lm / W or more, which makes the energy saving reform of streetlight in city possible. LED streetlight, especially high-power LED streetlight, is striking the traditional streetlight market at a rapid pace.
The general technology standards of current LED streetlight introduced by ENELTEC are as follows:
1. Light conversion rate: 17%. (The amount of solar energy per square is 1000W, actual utilization efficiency is 170W)
2. The current lens of market streetlight are improved optical materials, transmittance ≥ 93%, temperature resistance is from -38 degree to +90 degree.
3. The light spots of lens mainly used for LED streetlight are in rectangular. These lens use PMMA optical materials, transmittance ≥ 93%, temperature resistance is from -38 degree to +90 degree, resistance to UV yellow rate reaches 30,000 hours without change.
4. The average illumination of the uniformity of road surface illumination is 0.48. Light spot ratio is 1:2
5. It meets the road illumination. (Actual 1/2 center spot reaches 25LUX, 1/4 center beam intensity reaches 15LUX, the minimum light intensity of 16 meters is 4LUX, overlapping light intensity is about 6LUX.
6. It has a very good application prospect in the new city lighting. When dimming for depth, it does not change the colors and other characteristics
7.Working humidity: ≤ 95%
8. Warranty: 2 years
