Solar lawn lamp is a green energy lamp, which has the characteristics of safety, energy saving, environmental protection, easy installation, etc. Solar lawn lamp is mainly composed of light source, controller, battery, solar cell module, lamp body and other components. Under the illumination of light, it stores the electric energy in the battery through the solar cell, and in the absence of light, it sends the electric energy of the battery into the load LED through the controller. It is suitable for residential community green lawn beautification lighting and park lawn beautification.

A complete solar lawn lamp system includes: light source, controller, battery, solar cell module and lamp body.

When the sunlight shines on the solar cell in the daytime, the solar cell converts the light energy into electric energy and stores the electric energy in the battery through the control circuit. After dark, the electric energy in the battery supplies power to the LED light source of the lawn lamp through the control circuit. At daybreak the next morning, the battery stopped supplying power to the light source, the lawn lamp went out, and the solar cell continued to charge the battery, working in cycles. The controller is composed of a single chip microcomputer and a sensor, which controls the opening and closing of the light source part by collecting and judging the light signal. The lamp body mainly plays the role of system protection and decoration in the daytime to ensure the normal operation of the system. The light source, controller and battery are the key factors to determine the performance of lawn lamp system.
