Energy-saving principle rural street lamp installation of solar street light

As is known to all, is the biggest advantage of energy saving, solar street lamps but how specific energy-saving but few understand, so how energy-saving solar street light? To explore a: solar panels to energy storage? Solar panels during the day can not only provide electricity



it is well known that the biggest advantage is energy-saving solar street lamps, but how specific energy-saving but few understand, so how energy-saving solar street light? To explore a: solar panels 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 How to storage? Solar panels not only can provide electricity during the day, but also can provide electricity in the night. Solar panels is the same as the transistor, which is composed of a semiconductor. It is the main material of silicon, there are also some other alloys. The surface of the solar panel is made up of two different properties of parts. 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, generally can emit equivalent to 1/10 receives light energy to electricity. In order to make the solar panels to minimize light reflex, turn light energy into electrical energy, usually in are covered with a layer above it prevents the light reflection film, make the surface of the solar panels are purple. Second: how light energy into electrical energy? According to introducing, solar street lamp is mainly composed of four parts: pv modules convert light energy into electrical energy, light-emitting diodes (leds) 【 The light emitting diode LED for short. 】 , solar cells, solar battery charge and discharge and control of 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. To explore three: street light control switch? When street lamps are installed on the controller to play a role, according to the requirements of different lights can be 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 addition, due to the installation location of the environmental indicators, solar street lights will be effective daylighting can produce a considerable impact. Researchers also can be used according to the daily lighting time, to ensure the maximum number of days of a lighting and street light bulbs, etc. , used according to demand to design the size of the battery.
