Let's understand the component composition of solar lawn lights

A complete set of solar lawn lamp system includes: light source, controller, battery, solar cell components and lamp body. When daylight sunlight shines on the solar cell, the solar cell converts the light energy into electrical energy and stores the electrical energy in the storage battery through the control circuit. After dawn, the electric energy in the storage battery powers the LED light source of the lawn lamp through the control circuit. At dawn the next morning, the battery stops supplying power to the light source, the lawn lamp is calmed down, and the solar battery continues to charge the battery, cyclically and cyclically. The manipulator is composed of a single-chip microcomputer and a sensor. After collecting and discriminating light signals, it controls the on and off of the light source part. The lamp body mainly plays the role of system protection and day-to-day decoration to ensure the normal operation of this system. In the meantime, the light source, controller and battery are the key to determining the function of lawn lamp system. Solar cells convert solar energy into electric energy. There are three types of solar cells: monocrystalline silicon, polycrystalline silicon, and amorphous silicon. The functional parameters of monocrystalline silicon solar cells are relatively stable, and they are suitable for use in southern areas where there are more cloudy and rainy days and insufficient sunlight. The production process of polycrystalline silicon solar cells is relatively simple, and the price is lower than that of monocrystalline silicon, which is suitable for use in the east and west regions with sufficient sunlight. Amorphous silicon solar cells have relatively low requirements for sunlight conditions, and are suitable for local use where outdoor sunlight is lacking. The operating voltage of the solar battery is 1.5 times the voltage of the supporting battery to ensure that the battery is charged normally. For example, 4.0~5.4V solar cells are used to charge 3.6V batteries; 8~9V solar cells are required to charge 6V batteries; 15~18V solar cells are required to charge 12V batteries.
