Title:
MULTIFUNCTIONAL EMERGENCY LED BULB WITH STAND-BY POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2017/045090
Kind Code:
A1
Abstract:
A multifunctional emergency LED bulb with a stand-by power supply. The bulb comprises a CC-CV control circuit, a battery charging and discharging protection circuit, a battery, a charging state display module, a UPS digital detection control circuit, an LED dimming circuit and an LED light-emitting source; the UPS digital detection control circuit is connected to the CC-CV control circuit, the battery charging and discharging protection circuit, the battery and the LED dimming circuit; the CC-CV control circuit, the battery charging and discharging protection circuit, the battery and the charging state display module are connected successively; the LED dimming circuit is connected to the LED light-emitting source; the CC-CV control circuit is connected to a mains power supply; a positive electrode end of the LED light-emitting source is connected to the LED dimming circuit; and a negative electrode end of the LED light-emitting source is connected to a UPS digital dimming control circuit via a triode Q1. A UPS digital detection control circuit enables an emergency LED bulb to have a flash light function, an emergency illumination function, a conventional illumination function and a brightness memory function when a lamp is turned off, i.e. the adjusted brightness can be memorized from when the lamp was turned off the last time, and automatic switching can be realized; and an LED dimming circuit can adjust the brightness of an LED light source, so as to satisfy the use requirements.
