Operating principle

Description of the working principle of the solar street lamp: under the control of the intelligent controller in the daytime, the solar cell panel absorbs the solar light and converts it into electric energy through the sunlight, the solar cell module charges the battery pack in the daytime, and the battery pack provides power to the LED light source at night to realize the lighting function. The DC controller can ensure that the battery pack will not be damaged due to overcharge or overdischarge, and has the functions of light control, time control, temperature compensation, lightning protection, reverse polarity protection, etc

Components

Solar street light system can ensure normal operation in rainy weather for more than 15 days! Its system consists of LED light source (including driver), solar panel, battery (including battery incubator), solar street lamp controller, street lamp pole (including foundation) and auxiliary materials and wires.

Generally, monocrystalline silicon or polycrystalline silicon solar cell modules are selected; High power LED light source is generally selected as LED lamp head; The controller is generally placed in the lamp pole, which has light control, time control, overcharge and overdischarge protection and reverse connection protection. The more advanced controller has the function of adjusting the lighting time in four seasons, half power function, intelligent charging and discharging function, etc; Generally, the storage battery is placed underground or there will be a special storage battery incubator. Valve regulated lead-acid batteries, gel batteries, iron aluminum batteries or lithium batteries can be used. The solar lamp works automatically without trenching and wiring, but the lamp pole needs to be installed on the embedded parts (concrete base).
