查询词典 will power

Using solar cell to absorb solar energy and store into battery by DC-DC charger during daytime. When in the night, battery will be discharged to white LED by optical sensor and control circuit. Since the weather maybe cloudy or rainy, there is a spare AC power supply loop consist of transformer, bridge rectifier, filter and voltage regulator to prevent battery undercharge or circuit maintain. When the output current of battery is less than the preset value, the power source of white LED lamp will be switched over to spare AC power supply loop by the comparative and switching circuit.
