When the voltage of the solar panel is lower than 4.4V, the solar panel is considered to be at night, the 1 pin of the control chip U1 outputs a low level, the MOS tube Q2 is cut off, the solar panel stops charging the battery, the 3 pin of the control chip U1 outputs a high level, the LED lamp is on at the moment, and the 14 pin of the control chip U1 outputs PWM signals with different duty ratios according to the selected functional mode and the human body induction module, so that the brightness and time of the LED are controlled. When the system works, the voltage of the battery pack is detected by the pin 2 of the control chip U1, the solar panel charges the battery in the daytime, and when the voltage of the battery reaches 8.8V, the charging circuit is cut off, namely the pin 11 of the control chip U11 is changed from high level to low level, so that the second protection can be provided under the condition that the self-contained protection function of the battery pack fails.
