Abstract

The invention relates to the safety technology field and particularly relates to an LED emergency lighting power source. The LED emergency lighting power source comprises a micro controller, a power amplifier driving circuit, a transformer, an LED voltage stabilization output circuit, an LED current monitoring circuit, an overdischarged electricity voltage protection circuit and a chargeable cell, wherein the micro controller is separately connected with the power amplifier driving circuit, the LED current monitoring circuit and the overdischarged electricity voltage protection circuit, the power amplifier driving circuit, the transformer and the LED voltage stabilization output circuit are sequentially connected, the LED voltage stabilization output circuit is further connected with an anode of an LED lamp, the LED current monitoring circuit is connected with a cathode of the LED lamp, the overdischarged electricity voltage protection circuit is further connected with the LED voltage stabilization output circuit, and the chargeable cell is connected with the transformer. The LED emergency lighting power source is advantaged in that control output electricity parameters in a discharging state can be monitored, strong compatibility is realized, and equipment fault maintenance cost can be further reduced.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to an LED emergency lighting power supply. Background technique [0002] At present, all kinds of emergency lighting lamps are widely used in shopping malls, hotels, hospitals, entertainment venues, industrial and mining, petrochemical, commercial office and civil buildings and other places. The emergency lighting lamps are connected to the mains, and are used for emergency lighting after the mains power failure, and for daily lighting at ordinary times. [0003] LED lamps have long service life and low energy consumption, and are especially suitable for use in emergency lighting lamps. At present, in many application fields, fire protection regulations require emergency lighting lamps to use LED lamps, which has led to the demand for LED emergency lighting lamps. [0004] LED emergency lighting power supply is the core component of LED emergency lighting fixtures, usually incl...
