Some places require high-power LED street lamps because of their geographic location. It literally means that a single power is greater than 1 watt. Why can such a high power be due to the use of new LED semiconductor light sources? The lighting standard of LED street lamps up to now is generally the average illuminance of pavement illumination uniformity is 0.48, which is greater than the national traditional standard of 0.42. The spot ratio is 1: 2, which is consistent with road illumination. (The actual half center light spot can reach 25LUX, the quarter center light intensity can reach 15LUX, the minimum light intensity at 16 meters away is 4LUX, and the limit of overlapping light intensity is about 6LUX.
