High Power Solar LED street light application
High power LED street light is a light emitting diode by the DC voltage lighting needs groups to achieve a new way of lighting, high brightness, good color and other characteristics; Also, because LED lights to low voltage DC input, with the Solar combined, making solar LED lights has become a way of the future as a possible road illumination.
High Power Solar LED street light
In today¡¯s environment of global energy shortage, energy conservation has become a trend. Meanwhile, the state also vigorously promote energy conservation, has ended the 2008 Beijing Olympics and the upcoming 2010 Shanghai World Expo are invariably to green energy as the theme, which gives the Chinese LED lighting industry development has brought great historical opportunity . High-power LED with high luminous efficiency, low power consumption, long life, high stability, pure light color, good security, control, etc., is gradually replacing conventional light sources have been widely used in full-color display, traffic lights, car lights, background lighting, landscape lighting, special lighting and other work to become a new generation of green lighting source. According to domestic agencies predicted that in the Olympics, World Expo strong, driven by China¡¯s LED lighting market size of 4.85 billion yuan from 2007 to 2010, the rapid growth of 9.81 billion yuan. Relevant experts believe that China LED lighting industry in 2010 ushered in a new development before and after the peak.
Currently, LED lighting technology matures, high-power LED light effect has reached 80lm / W or more, which makes the city street lighting energy saving is possible. LED lights, especially in high-power LED lights, the impact of being at a rapid pace traditional street market.
High-power LED lights standard generally:
1. Light conversion rate of 17%, (the amount of solar energy per square 1000W, actual utilization efficiency 170W)
2. The current market streetlight lens material for the improvement of optical materials, transmittance ¡Ý 93%, temperature -38 ¨C +90 degrees.
3.LED lamp lens, the lens is mainly used for LED lights, spot rectangular material is PMMA optical materials, transmittance ¡Ý 93%, temperature -38 ¨C +90 degrees, `yellow UV protection rate of 30,000 hours without changes,
4 road illumination evenness (uniformity of road surfaceilluminance) the average illuminance 0.48. Spot ratio 1:2
5 meets the road illumination. (Actually 1/2 center spot reached 25LUX, 1/4 center beam intensity reached 15LUX, 16 meters from the minimum light intensity 4LUX, overlapping light intensity of about 6LUX.
6 It is in the new city lighting has a very good application prospects. Dimming for depth, and the colors and other characteristics will not change due to dimming.
7. Adaptation humidity: ¡Ü 95%
