Features of LED street lights
Street lamp features: suitable for main roads, secondary roads, campus roads, square roads, township roads, etc.
The road is the artery of the city. The main lighting is a street lamp, which is a lighting facility that is set on the road to provide necessary visibility for vehicles and pedestrians at night. Road lights can improve traffic conditions, reduce driver fatigue, and help improve road capacity and ensure traffic safety. Garden lights, landscape lights and street lights form a three-dimensional lighting pattern, which enhances the effect of road decoration, beautifies the night scene of the city, and can also make up for the lack of illumination of road lights. Road lamps need to have reasonable light distribution, and their light sources have a long life and are maintenance-free for year-round use. It has the characteristics of high light efficiency, good color rendering, and can start normal work in an ultra-low temperature environment. At present, common street lamps include incandescent lamps, high-pressure sodium lamps, low-pressure sodium lamps, induction lamps, metal halide lamps, and fluorescent lamps. At this stage, the important product of road lighting sources is still high-pressure sodium lamps. In recent years, due to the country's vigorous promotion of energy saving and emission reduction, as a new type of light source, electrodeless lamps can achieve better uniformity on the road surface than traditional light sources. Road lights should use light energy reasonably to prevent glare. The light emitted by it should be irradiated along the required angle, and fall on the road surface in a designated pattern, with uniform light distribution, high brightness on the road surface, and low glare. In order to reduce glare, the light distribution can be controlled above the light intensity. According to the road section, width, vehicle and pedestrian conditions, road lights can be arranged symmetrically on both sides of the road, staggered on both sides, on one side, and suspended in the center of the road. Generally speaking, for roads and welcome roads with a width of more than 20 meters, symmetrical arrangement on both sides can be considered; for roads with a width of more than 15 meters, staggered arrangement on both sides can be considered; narrow roads can be arranged on one side. At road intersections, bends, ramps, railway crossings, crosswalks and other special places, road lights are generally set up to help drivers and pedestrians recognize the road conditions. In the lighting of the sections inside and outside the tunnel and the transition section from urban streets to suburban roads, it is necessary to consider the adaptability of the driver's eyes to changes in light. The power, installation height, and longitudinal spacing of road lights are important parameters for light distribution design. By combining these three factors, a satisfactory lighting effect can be obtained.
