Description
technical field [0001] The invention relates to a lighting circuit, in particular to a lighting lamp circuit capable of uninterrupted power supply. It also relates to a lighting lamp containing the circuit. Background technique [0002] Now, human life is inseparable from electric lighting. At present, our lighting lamps are all connected in parallel to the 220 volt power supply by the illuminant through the switch, controlled by the switch, relying on the power supply, the light turns on when it is turned on, and it goes out when it is turned off. If the power is cut off, there will be no lighting. Therefore, people have set up a kind of emergency light in the aisle of some public places, which is used for emergency lighting during power failure. The emergency light is powered by a storage battery to make the illuminant emit light, and the storage battery automatically supplies power when the power fails. Once this kind of emergency light storage battery is powered, it ...
