Solar lights characteristics: energy: solar photovoltaic provide electricity, inexhaustible. ? Environmental protection: no pollution, no noise, no radiation. ? Security: no electric shock, fire and other accidents. ? Convenience: installation is simple and does not require the overhead line or "disembowel" dig construction, there is no power brownouts concerns. ? Long life: high-tech products, control systems, accessories are an international brand, intelligent design, reliable quality. ? Grade high: tech products, green energy, and use of attention to science and technology, green image improve, upgrade. ? 1, solar panels: the solar panels are the core part of the solar lights. Its role is to convert solar radiation into electricity stored in batteries supplied. Among the more common solar cells and more practical monocrystalline silicon solar cells, three polycrystalline silicon solar cells and amorphous silicon solar cells. 2, solar controller? No matter the size of solar lamps, a good performance of the charging and discharging controller is essential. To prolong battery life, it must charge and discharge conditions to limit, prevent battery overcharge and depth charge. In the large temperature difference, the controller should have qualified temperature compensation function. While solar street light controller should both control functions, with light control, time control function, and should have at night is automatically cut control load function, easy to extend the working hours street rainy days. ? 3, the battery? Because the input energy solar photovoltaic system unstable, it is generally required to configure the battery system to work. Choice of battery capacity generally follow the following principles: First, to meet the premise of lighting at night, the energy of the solar cell module as much as possible during the day and stored, but also capable of storing electrical energy to meet the continuous rainy days night lighting needs. 4, the light source??? What kind of light is an important indicator of whether the normal use of solar lamps, solar lamps generally low-pressure energy-saving lamps, low pressure sodium lamp, lamp, LED, HID and other sources. Wherein the LED light source as solar street lighting is a trend. 5, the poles and lamp housing???? Pole height should be based on the width of the pitch roads, lighting and illumination standards to determine the road. Exterior lighting less demanding, the relative utility line. ? Internal structure of the solar street light product: the internal structure of solar lights and solar garden lights and light poles in addition to the different shape, the other main components are the same, but the parameters are different, it can be divided into: Solar light controller, solar batteries, Buried battery box, solar panel module, LED light source, light pole, cage, cable; solar LED lights, it is not only a high luminous efficiency and long service life, with the continuous development of technology, LED light source gradually been widely used solar street lamps and ordinary city circuit lamp. I believe in the near future solar LED lights and mains LED lights will soon be replaced by an ordinary street. David Carse, Sichuan Desheng Lighting Technology Co., Ltd.
