Abstract

The invention relates to a solar energy illuminating control power supply, which can synchronously output direct current of 12V or 24V and alternating current of 220V / 50Hz or 110V / 60Hz through a solar panel and the input of commercial power and ensure direct current and alternating current supply for LED lamps or other energy-saving lamps in overcast and rainy seasons to achieve the aims of environmental protection and energy conservation. Based on the prior solar energy charge power supply, the solar energy illuminating control power supply is also provided with an alternating current complementary power supply unit and an inverter; the commercial power is subjected to AC / DC conversion of the alternating current complementary power supply unit and then output to an input end of a direct current output switch; the other input end of the alternating current complementary power supply unit is connected with an output / input end of an accumulator battery, the voltage of the accumulator battery is detected, and the AC / DC conversion of the alternating current complementary power supply unit is controlled; and the inverter is connected between a cathode end of a diode and the other path of signal control output end of a power supply output control circuit, and outputs the alternating current.

Description

technical field

[0001] The invention relates to the field of solar power supply control devices, in particular to a solar lighting control power supply. Background technique

[0002] The existing solar street lamp lighting control power supply is mainly composed of solar panels, solar charge controllers, battery packs, and DC voltage regulator circuits, and outputs 12V or 24V DC power for LED lamps or DC-operated lighting fixtures. In order to solve the problem that the solar lighting control power supply cannot be powered normally due to rainy weather for a long time, one way is to convert the input AC power into DC power to charge the battery pack, so as to maintain the normal power supply to the LED lights. This method has been used in China The patent announcement number is disclosed in the patent specification CN201113498Y; another way is to input alternating current through the rectification circuit to step down and rectify and then supply power to the LED. This way ha...
