Abstract

The invention discloses a capacitor emergency lamp and a power supply method therefor. The capacitor emergency lamp comprises a lamp body, a power supply unit and a processing control unit; the powersupply unit comprises a mains supply module and a capacitor module; the lamp body is electrically connected to the mains supply module and the capacitor module; the mains supply module and the capacitor module are controllably connected to the processing control unit, wherein the processing control unit further comprises a detection module and a control module; the detection module is in communication interconnection with the power supply unit, and the detection module is used for detecting the circuit state of the power supply unit; and the control module selects one of the mains supply module and the capacitor module to supply electric energy for the lamp body according the detection result of the detection module.

Description

technical field [0001] The invention relates to emergency lighting or indicating equipment, in particular to an emergency light powered by a capacitor and a power supply method thereof. Background technique [0002] Capacitors, especially supercapacitors, have been proven to be useful for power supply. However, because the capacity of the capacitor is insufficient and the discharge is too fast, it is not suitable for most power supply situations. However, the power supply needs of emergency equipment are just different from the needs of general power supply situations. For example, in the case of a sudden power failure at night, the emergency light uses the capacitor module to provide power supply to provide lighting; in the case of a fire and power failure, the emergency light can also use the backup power supply to provide light through the smoke to indicate the direction and exit , location, and more. Based on safety needs, lighting systems are required in many indoor ...
