Emergency power supply module compatible with LED lamp

Abstract

The invention discloses an emergency power supply module compatible with an LED lamp. A storage battery is arranged in the emergency power supply module, a live wire access end and a zero line accessend of the emergency power supply module are connected with a control switch, the first output end of the emergency power supply module is connected with the live wire access end of the LED lamp, andthe second output end of the emergency power supply module is connected with the zero line access end of the LED lamp. When the commercial power is connected, if the power level of the storage batteryis low, the power supply module charges the storage battery; when the storage battery is fully charged, charging is stopped; when the commercial power is normal and the control switch is closed, theemergency power supply module outputs voltage to supply power; when the commercial power is abnormally powered off, if the control switch is closed, the emergency power supply module supplies power tothe LED lamp through the storage battery in the emergency power supply module, and no matter whether the mains supply is normal or abnormal, the emergency power supply module does not supply power aslong as the control switch is disconnected. The power supply module has the advantages that the LED lamp with the emergency lighting function is formed by being directly and additionally arranged outside an existing LED lamp, the cost is low when the existing LED lamp is refitted into the emergency LED lamp, resource waste cannot be caused, the design of the LED lamp cannot be limited by a storage battery, and the LED lamp has high cost performance.

Description

technical field [0001] The invention relates to an emergency power supply module, in particular to an emergency power supply module compatible with LED lamps. Background technique [0002] LED lamps powered by mains have become the current mainstream lighting fixtures and have been widely used. The LED lamp has a live line access terminal and a neutral line access terminal, and is connected to the live line and neutral line of the mains through the control switch. The voltage of the electricity is the same, at this moment, the LED light emits light, and when the control switch is disconnected, the voltage between the live wire input end and the neutral line input end is zero, and the LED light does not emit light at this time. Existing LED lamps usually have a voltage threshold. When the connected voltage is greater than or equal to this voltage threshold, the power consumption and brightness of the LED lamp remain unchanged. When the connected voltage is less than this vol...

Problems solved by technology

However, it is precisely because of this structure that the design of the LED lamp will be limited by the low operating temperature of the battery and cannot achieve the best cost performance

Moreover, at present, when users put forward emergency lighting needs, they need to use LED lights with emergency lighting functions to completely replace the original traditional LED lights, and the replacement cost is high. big waste of resources
