Solar LED street lamp consists of the following parts: solar battery, battery, controller, specially used for solar street lamps light source and light pole. Solar cells to accept sunlight to produce electricity during the day, through the charge controller to battery, the electrical energy stored in the
solar led street light by solar batteries, battery, controller, specially used for solar street lamps light source, and a light pole. Receiving sunshine during the day, the solar cells to generate electricity by charging controller to recharge the battery, the electrical energy stored in the battery. Dark, namely solar stop charging, open source, charging controller and delay in 6 - Closed after 10 hours. Electric energy can be used in the battery light working 50 hours straight, work 10 hours a day, sustainable 5 days. Solar led street light has the following advantages: ( 1) Solar lighting installation is simple: when installing solar lights, do not need to laying complex lines, cable laying can save much cost, only need to do a cement base, stainless steel screws. ( 2) Solar lighting don't accept bills: solar lighting is a one-time investment, no maintenance, will benefit in the long run. ( 3) Solar lighting without a safety hazard: solar lamps and lanterns for the low voltage products, safe and reliable operation. ( 4) Simple installation, free maintenance, energy conservation, environmental protection, in line with the national energy conservation and environmental protection requirements, responded to the requirements of the new energy use. ( 5) Light emitting diode lamp long life, energy saving effect is obvious: compared with the traditional high pressure sodium lamp, led street lamp holder can be energy-saving 60% 65%, the life can reach 30000 hours. ( 6) Improve the image of the city management: set up the energy saving and new energy city flag. Solar led streetlight lighting inherent safety, energy saving, environmental protection, simple installation, automatic control, free maintenance etc, directly bring a clear advantage to the municipal engineering construction.
