What is the principle of the solar street light?

As new measures of energy saving, solar street light for energy-saving out more vigorously? As new measures of energy saving, solar street light for energy-saving out more vigorously? 1, energy saving economy first, every solar street light is a relatively independent system, at the time of installation without embedded cable, also need not excavation road, saves quite a lot of manpower and installation costs; Besides, power consumption, an ordinary street lamp lighting time is about 6 hours a day, the power consumption of about 2 degrees, need a year 300 multivariate electricity, a city calculated at 300 streetlights, will cost nearly 100000 yuan a year, with the solar street light under the province. According to reports, the new outdoor lighting lamps 50 million a year, if solar lamp can account for one over one thousand, a year will be able to save hundreds of millions of degrees, equal to the state sent a 100000 mw power station. 2, the energy conservation principle 2. 1 how solar panels energy storage? Main material is silicon solar panels, there are also some other alloys. When the solar panels by light irradiation, can convert light energy into electrical energy, make the current flow from one side to the other party. Solar panels is according to the principle of this design. Solar panels, as long as by sunlight or lamplight illuminate, general electric could be sent to. In order to make the solar panels to minimize light reflex, improve the photoelectric conversion rate, generally on top of it is covered with a layer of prevent light reflection film, make the surface of the solar panels are purple. In addition, the inclination of the solar panels, solar street lights can effectively lighting will have considerable impact. 2. 2 how light energy into electrical energy? Solar street lamps mainly consists of four parts: photovoltaic modules, light emitting diode, solar battery and the controller. Photovoltaic modules to absorb light during the day, convert solar energy into electrical energy storage in solar cells, to discharge lighting when it is dark at night. Sunny days commonly, under the ideal light intensity, full of electricity, as long as four hours per charge can guarantee up to five days after the completion of the above, continuous rain 3 days also can work normally. In addition, the LED street lamp, according to different requirements, the controller can be solar street light switch is designed for electric or time control, not only the storage battery charging and discharging time can be controlled, can also control the intensity of discharge size. In short, in the energy consumption is more and more big in the city, the city electricity has not its weight: industrial electric power consumption in recent years, life has been high, rising year by year, many cities peak electricity is more common. If solar street lamps can widely spread, people don't have to worry about affected the normal production and living.
