Emergency lighting integrated LED (light emitting diode) lamp fixture

Abstract

The invention discloses an emergency lighting integrated LED (light emitting diode) lamp fixture which comprises an LED lamp string, a constant current source circuit, a battery constant-current charge circuit, a commercial power detection and control circuit and a booster circuit, wherein the commercial power detection and control circuit is respectively connected with the constant current source circuit, the battery constant-current charge circuit and the booster circuit; the battery constant-current charge circuit is connected with the constant current source circuit; and the constant current source circuit and the output end of the booster circuit are also connected with the LED lamp string. The circuit structure provided by the invention not only can detect accurately through electric detection and the control circuit, but also a rapid conversion effect can be achieved, and the flexibility is improved greatly; and relative to the traditional circuit, each function part of the circuit is designed by adopting integration, the circuit structure is more simple, also the emergency lighting time is prolonged greatly relative to the emergency lamp at the market, thus the emergency lighting integrated LED lamp fixture has a bright application future.

Description

technical field [0001] The invention relates to the field of LED lighting lamps, in particular to an integrated LED lamp for emergency lighting. Background technique [0002] LED lighting fixtures are lighting devices widely used indoors and outdoors. With the development of economy and society and the continuous improvement of lighting technology, the functions and application range of LED lighting fixtures have gradually expanded. [0003] LED emergency lighting is a kind of LED lighting fixtures, which are mainly used in shopping malls, hospitals and underground facilities that require uninterrupted lighting. The basic working principle of LED emergency lighting is to start the emergency lighting function when there is no mains power. The existing emergency lighting generally uses a built-in rechargeable battery to provide power for the system, and the rechargeable battery is charged when there is mains power. , in the absence of mains power, the system is powered by a r...

Problems solved by technology

The basic working principle of LED emergency lighting is to start the emergency lighting function when there is no mains power. The existing emergency lighting generally uses a built-in rechargeable battery to provide power for the system, and the rechargeable battery is charged when there is mains power. , in the absence of mains power, the system is powered by a rechargeable battery, which requires efficient and reliable system performance. Most of the LED emergency lights currently on the market have low sensitivity in the conversion mode of the mains battery and complex detection and control systems. And defects such as too short emergency lighting time
