Can the lighting time of solar street lamps meet the urban road lighting standards?

The height of the solar street light pole should be determined according to the width of the road, the spacing of the lamps, and the illuminance standard requirements of the road. The housing of the lamp can choose between aesthetics and energy saving according to the requirements. Most customers will choose energy saving, and the appearance of the lamp is not high, and it is relatively practical. According to the relevant regulations of 'Design Standards for Urban Road Lighting': the average illuminance of expressways is 20lx, the uniformity is 0.4, the average illuminance of main roads is 15lx, the uniformity is 0.35, the average illuminance of secondary roads is 8lx, the uniformity is 0.35, and the average illuminance of branch roads is 5lx, uniform. Degree 0.3. The solar street lights currently in use, due to technical conditions, the power of the LED light source is 30~100w, the light efficiency is 50~80lx/w, and the road illumination is low. According to relevant tests, the pole height is 8.5 meters, the spacing is 30 meters, and the LED light source is 2× 50w, the illuminance under the lamp is 19lx, between the two lamps is 11lx, and the darkest place is 3.5lx. The daily working hours of solar street lamps should be equal to the working requirements of general street lamps, and the design should consider that when the sunshine time in winter is short, the working time should be more than 10 hours. Since solar street lights are greatly affected by the weather, in case of continuous rainy days, the solar street lights lack power and cannot be used. There is currently no national standard for solar street lamps in low irradiance (continuous rainy days), and there is no relevant provision for the minimum working time allowed. Working conditions are 10 to 15 days. The capacity of solar panels and batteries should be fully considered in the design. For details, please visit: http://www.chz-lighting.com .
