Abstract
The application provides an emergency power supply circuit and a lighting device. A main control unit monitors an output voltage of a charging circuit; when the charging circuit is abnormal, an auxiliary power supply is connected to an energy storage unit by means of an auxiliary power supply control circuit to charge the energy storage unit to ensure the power supply stability of the energy storage unit; a boost unit is controlled to be turned on by means of a boost control circuit to boost an output voltage of the energy storage unit to ensure that the output voltage can satisfy the operating voltage requirement of a load; and the boost circuit is electrically connected to a drive control unit by means of a feedback unit to regulate the output volage in real time so as to provide a stable boosted voltage for the load.
