The technology is becoming more and more mature, and the efficiency of the light source has reached more than 100lm/W, which makes the energy-saving renovation of urban street lighting possible. LED street lamps, especially high-power LED street lamps, are hitting the traditional street lamp market at a rapid pace.
As the name implies, high-power LED street lights are street lights with a power of more than 30 watts and using new LED semiconductor light sources. The standard is generally the uniformity of pavement illuminance, which is consistent with road illuminance. (The actual 1/2 center light spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the minimum light intensity at 16 meters away is 4LUX, and the overlapping light intensity is about 6LUX. It refers to the LED street lamp that uses solar silicon plates as the power supply.
1. The light conversion rate is 17%, (the solar energy per square meter is 1000W, the actual utilization efficiency is 170W)
2. The market street lamp lens material is an improved optical material, the transmittance is ≥93%, the temperature resistance is -38-+90 degrees, and the UV resistance and the yellowing rate are unchanged at 30,000 hours.
3. LED street lamp, mainly used for the lens of LED street lamp, the light spot is rectangular, the material is PMMA optical material, the transmittance is ≥93%, the temperature resistance is -38－+90 degrees, and the anti-UV ultraviolet` yellowing rate is unchanged at 30,000 hours Wait,
4. The average illuminance of uniformity of road surface illuminance is 0.48, and the spot ratio is 1:2.
5. Meet the road illumination. (The actual 1/2 center light spot reaches 25LUX, the 1/4 center light intensity reaches 15LUX, the minimum light intensity at 16 meters away is 4LUX, and the overlapping light intensity is about 6LUX.
6. It has very good application prospects in new urban lighting. Dimming of depth, and color and other characteristics will not change due to dimming.
7. Adapt to humidity: ≤95.
Despite the rapid development of LED street lamps, the standard of LED street lamps is relatively lagging behind. On the global scale, there are not all standards for LED street lights, like European standards for LED street lights. In fact, the standards for LED street lamps in different regions are different in terms of indicators. LED street lamps must meet the requirements of the sales area in terms of standards. Therefore, bidding for the LED street lamp project needs to study the local LED street lamp standards in depth, and only then will it be intense Has a place in the market competition.
