The technology is becoming more and more mature, and the light source efficiency has reached more than 100lm/W, which makes the energy-saving renovation of urban street lighting possible. LED street lights, especially high-power LED street lights, are hitting the traditional street light market at a rapid rate.
High-power LED street lamps, as the name implies, are street lamps with a power of more than 30 watts and a new LED semiconductor light source. The standard is generally the uniformity of the road illumination, which is in line with 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 4 LUX at 16 meters, and the overlapping light intensity is about 6 LUX. It refers to the LED street light using solar silicon plate as the power supply.
standard
1. The conversion rate of light is 17%, (1000W per square meter of solar energy, the actual utilization efficiency is 170W)
2. The market street lamp lens material is an improved optical material with a transmittance of ≥93%, a temperature resistance of -38-+90 degrees, and an anti-UV ultraviolet ray yellowing rate of 30,000 hours without change.
3.LED street light, 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 degrees, the anti-UV ultraviolet yellowing rate is 30,000 hours without change. Wait,
4. The average illuminance of the uniformity of road surface illumination is 0.48, and the spot ratio is 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.
Despite the rapid development of LED street lights, the standard of led street lights is relatively lagging behind. On a global scale, LED street lights are not standard, as is the European standard for LED street lights. In fact, the standards for LED street lamps in different regions are different in terms of indicators. LED street lamps should meet the requirements of the sales area on the standard. Therefore, bidding for LED streetlight projects should thoroughly study the local LED street lamp standards. Only in this way will it be fierce. It has a place in the market competition.
