How many lights can a high-power LED lamp be at least W?
At present the market street lamp lens material for the improvement of optical materials, transmittance is more than 93%, high temperature -38 +90, anti ultraviolet UV ` etiolating rate for 30000 hours without change. It has a very good application prospect in the new city lighting. Dimming for depth, and colors and other features are not subject to dimming.
At this stage of the rural minimum power lights are 20W, 40W, is mainly based on the width of pavement, street lamps light efficiency, light cloth density, the installation height of the future, the light effect is improved, the minimum power may be smaller than the current lights, high power LED lamps, small power can do big to about 80LM/W. Power can do about 90LM/W street.
High power LED street lamp, as the name suggests, is a single power greater than 1 watts, using a new type of LED semiconductor light street lamps. At present, the standard of LED street lamps is generally the average illuminance of (uniformity of road surfaceilluminance), which is greater than 0.42 of the national standard. The spot ratio is 1:2, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.
