Currently, LED lighting technology matures, high-power LED light source effects have reached 80lm / W or more, which makes the city street lighting energy saving possible. LED lights, especially high-power LED street light, the impact of a rapid pace is the traditional street market.
High power LED street lamp suggests that it is greater than 30 watts or more, the semiconductor light source using the new LED lights. Currently the standard LED lamp illumination uniformity is generally the road (uniformity of road surfaceilluminance) the average intensity of 0.48. Spot ratio of 1:2, in line with the road illumination. (Actually 1 / 2 center spot to 25LUX, 1 / 4 center of light intensity to 15LUX, 16 meters from the lowest light intensity 4LUX, overlapping light intensity of about 6LUX. Lamp lens materials currently on the market improved optical materials, transmittance ≥ 93% , temperature -38-- +90 degrees, anti-yellowing UV UV `unchanged rate of 30,000 hours and so on. It is in the new city lighting has a very good prospect. on the depth of the dimming, and color and other characteristics will not changes due to dimming. Solar LED lights is that the use of solar silicon panels to supply power LED lights.
Currently the standard LED lights typically are:
1. Light conversion rate 17% (amount of solar energy per square 1000W, the actual utilization efficiency 170W)
2. Lamp lens materials currently on the market improved optical materials, transmittance ≥ 93%, temperature -38-- +90 degrees.
3.LED lamp lens, mainly for the LED lights of the lens, the spot is rectangular, the material is PMMA optical material, transmittance ≥ 93%, temperature -38-- +90 degrees, anti-UV UV `rate of 30,000 hours without yellowing change,
4. Road illumination uniformity (uniformity of road surfaceilluminance) the average intensity of 0.48. Spot ratio of 1:2
5. Comply with the road illumination. (Actually 1 / 2 center spot to 25LUX, 1 / 4 center of light intensity to 15LUX, 16 meters from the lowest light intensity 4LUX, overlapping light intensity of about 6LUX.
6. It is in the new city lighting has a very good prospect. Dimming of the depth and color and other characteristics will not change due to dimming.
7. Adaptation Humidity: ≤ 95%
8. Quality guarantee: 2 years
The rapid pace of development of LED lights, led lights, but the standard is relatively slow. On a global scale, LED street lights are not standard is not, like LED lights, there are now European standards. In fact, all regions of the LED lights of the standard, indicators are different, we have done in the standard LED lights to meet the sales area on the requirements, so tender-depth study of LED street lamp project to the local standard of LED lights, the only way will be in shock cracking competition in the market place.
