The integrated solar street lamp is strong, concise and beautiful, convenient for transportation and installation. In the daytime, it can not only charge the solar panel as a lithium battery, but also be used as a landscape decoration; After the light goes dark, the controller automatically judges to supply power for the LED lamps of all solar street lamps through the preset period of time and the voltage detection of the solar panel to achieve road lighting. The existing LED outdoor all solar street lamps on the market mainly include the following types: the integrated solar street lamps shown in Figure 1 (a) and Figure 1 (b, It virtually increases the additional cost of solar lamps. Figure 1 (c) shows that the solar panel and lamp shell are made into a whole type. Although the appearance is concise and beautiful, it is not conducive to the heat dissipation of the lamp beads. It limits the power of the lamps and cannot adjust the orientation of the solar panel, so that the solar panel cannot efficiently convert solar energy into electric energy.

The planning idea of all thin solar street lamps is the same as the basic principle of general solar lighting (as shown in Figure 2). All thin solar street lamps convert the collected solar energy into electric energy through solar panel components in the daytime. The battery is charged by the charge and discharge controller, as well as various battery tests and safety protection. At night or when the light is dark, the battery supplies power to LED lamps through the street lamp controller, and LED street lamps are lit for lighting.

After the principle is clarified, we divide it into the following parts according to the different functions of each part of the circuit: solar panel module, impulse discharge controller, street lamp controller, LED street lamp, and battery. The purpose of this planning scheme is to provide a whole type of thin solar street lamp, which can be used for various rural roads, auxiliary traffic roads, residential areas, park roads, and places without light shielding but not easy to be electrified to provide road lighting at night. The technical problems to be solved are light and fashionable appearance, convenient transportation, convenient on-site devices, and micro blog sensing function. It is necessary to ensure its structural safety, reliability, durability and electrical safety.
