The cumbersome preparation engineering such as pipe laying, unwrapping wire, saves manpower and material resources and expenditure budget.And compared with conventional high-pressure sodium vapor lamp, the sun
Energy streetlight power consumption can save 4 times or so.With the acceleration of Chinese Urbanization construction process and adding for city capital construction Facilities Construction
Fastly, the market demand of illuminating product is gradually expanded in city.Under the overall background of energy shortage, conventional illumination device energy consumption is huge
Greatly, and there are huge energy wastes, hence it is evident that does not meet the developing direction of China's Energy restructuring, while also greatly limitation
The utilization efficiency of lighting apparatus.And the appearance of solar street light, effectively compensate for above-mentioned deficiency.Solar street light can drop
Low electric consumption on lighting amount is energy saving important channel.
Street lighting generally carries out at night or rainy days, therefore the working method of solar street light are as follows: solar battery
Under control of the controller by charging circuit daytime to charge the battery, and battery is being controlled in night or continuous rainy weather
Device control processed is lower to be started street lamp by electric discharge/driving circuit and adjusts brightness.In Solar Street Lighting System, solar panels make
