Walking under the solar street lights, it is not difficult for us to find that there are some problems in the installation of solar street lights. That is, we have a very bright brightness under the solar street light, and then when the next solar street light comes, there will be a dark area; in another case, the lighting area between the two lights overlaps. In fact, this situation occurs because the distance between solar street lights is too large, because the lighting angle of solar street lights is related to the height of the pole and the illumination angle of the light source. The general angle is between 60-130 degrees, so that it can cover With a large area and the same height of the poles, if there is a dark spot area, it means that the distance between the two lamps is slightly larger. If the irradiation area overlaps, the distance is too small, you need to increase the distance between the two lamps. , The significance of installing lights at a long distance is not reflected, and resources and energy are wasted when the distance is short, so reasonable configuration is required. We use solar street lights in the new countryside. Rural roads are 5-6 meters wide and need to be continuously lit for more than 4 hours as an example to configure and set solar street lights reasonably. Generally, roads like this choose single-sided lighting or asymmetrical lighting on both sides, and the light pole is selected to be 4-6 meters, so that the entire road can be covered. If LED30W lamp holder is used, then the angle of the lamp holder can be calculated to calculate the street lamp. For the coverage of the illumination range, scientific calculations can conclude that the illumination area of u200bu200bthe street lamp is approximately 35 meters, so the following conclusions can be drawn: a road with a width of 5 meters, using solar street lights, the height of the pole is 5-6 meters, about 30W Light source, 90W solar panel and 90AH battery (configuration can be changed according to requirements), the best distance between the lamp distance is about 35 meters. A reasonable configuration of a solar street light can prevent an unlit area or overlapping of the illuminated areas between the two lights in use.
