The working principle of solar street light is explained.
During daytime, under the control of intelligent controller, solar panel absorbs solar energy and converts it into electric energy by sunlight irradiation. The solar module charges the battery pack during the day, and the battery pack supplies power to the LED light source at night to realize the lighting function. The DC controller ensures that the battery pack is not damaged by over-charging or over-discharging, and has functions such as lighting control, time control, temperature compensation, lightning protection and reverse polarity protection.
Component components.
The solar street light system can guarantee normal operation for more than 15 days in rainy weather! The system consists of LED light source (including driver), solar panel, battery (including battery holding tank), solar street light controller, street light pole (including foundation) and auxiliary line. Solar cell components generally use monocrystalline silicon or polycrystalline silicon solar cell components; LED lamp head generally uses high-power LED light source; controller is generally placed on the lamp post, with lighting control, time control, overcharge and over-discharge protection and reverse connection protection, more advanced controller also has four seasons lighting time adjustment function, half-power function, intelligent charge and discharge function; iron and aluminum batteries or lithium batteries. Solar lights work fully automatically without trenching and wiring, but the poles need to be installed on pre-built parts (concrete base)
Solar street light The difference between and ordinary street lights.
A. Energy difference. Solar street lights use solar energy, ordinary street lights use electricity.
Second, the difference in voltage. Solar street lights generally use 12V or 24V system, ordinary street lights use 220V system.
Third, the differences in installation. Solar street lights are self-contained independent systems, no need to dig cable trenches, pre-buried pipelines, compared with ordinary street lights, solar street lights construction is more convenient.
Fourth, the difference in safety. Solar street light is a low-voltage system, will not cause harm to humans. Ordinary street light is a high-voltage system. Incorrect installation wiring or leakage will endanger human health.
Fifth, the difference between the light source. Solar street lights must use LED light source. Ordinary street lights can use LED light source or high-pressure sodium lamp.
Sixth, the price difference. Solar street light components, high quality requirements, so the price is relatively high, while the price of ordinary street lights is relatively low. Solar street lights and ordinary street lights have their advantages and disadvantages, and are widely used. Mainly based on the actual needs and site conditions to choose.
