Solar street lamp system can ensure the normal work of rainy weather for more than 15 days! The system consists of LED light source (including driver), solar panel, storage battery (including battery incubator), solar street lamp controller, lamp post (including foundation) and auxiliary material wires.
Generally, monocrystalline silicon or polycrystalline silicon solar cell modules are selected for solar cell modules; LED lamp holders generally use high-power LED light sources; The controller is usually placed in the lamp post, which has the functions of light control, time control, over-charge and over-discharge protection, reverse connection protection and so on. The more advanced controller has four-season dimming time, half-power function, intelligent charge and discharge and other functions. Batteries are usually placed underground or there will be a special battery incubator, which can be valve-regulated lead-acid batteries, colloidal batteries, iron-aluminum batteries or lithium batteries. The solar lamp works automatically, and there is no need to dig trenches for wiring, but the lamp pole needs to be installed on the embedded part (concrete base). Working principle of solar street lamp: During the day, under the control of intelligent controller, solar panels absorb sunlight and convert it into electric energy. During the day, the solar cell module charges the storage battery, and at night, the storage battery supplies power to the LED light source, realizing the lighting function. The DC controller can ensure that the battery pack is not damaged by overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection and reverse polarity protection.
