What are the working principle and product advantages of solar lawn lights?

First, the principle of solar lawn lamp

① solar lawn lamp is composed of solar cells (accept light to generate electricity for battery charging), charge and discharge controller (control battery charging and discharging state), battery (storage and power supply for the lamp source), lamp source (load) and lamp post composition.

② working principle of solar cells during the day to accept the sun's light to generate electricity (photovoltaic) issued by the electricity and then through the charge and discharge controller for the battery charging. Full of automatic power off, there will be no overcharging At night, through the charge and discharge controller, the battery for the light source (load) power supply. The controller will automatically control the working time of the light source and the discharge state of the battery according to the setting or usage. Controller it will not let the battery over discharge, which will lead to shorten the life of the battery.

Second, the advantages of solar lawn lights because it is the use of solar cell battery power supply, so it does not need to connect additional external power supply to give it power, eliminating the laying of cables and wiring and other cumbersome processes, and it does not need to be very demanding to arrange for a long time for people to maintain it.
