Description

LED照明应急灯
技术领域
本实用新型涉及一种LED照明应急灯。
背景技术
传统LED等一般包括市电电源、降压模块、整流稳流模块和照明模块,当停电时就无法用于照明。
发明内容
本实用新型所要解决的技术问题是提供一种LED照明应急灯,该应急灯能够在正常市电供电状态下蓄电,并能在停电状态下正常照明。
为此,本实用新型提供的LED照明应急灯,包括市电电源、降压模块、整流稳流模块和第一照明模块,还包括断电检测和应急启动模块、第二照明模块、驱动模块和蓄电模块,市电电源分别连接所述降压模块和驱动模块,降压模块又分别连接所述断电检测和应急启动模块和整流稳流模块,整流稳流模块连接所述第一照明模块,断电检测和应急启动模块连接所述第二照明模块和蓄电模块,蓄电模块又连接驱动模块。
由于本实用新型提供的LED照明应急灯中,采用了断电检测和应急启动模块、第二照明模块、驱动模块和蓄电模块,其中蓄电模块在市电电源正常供电时能够进行蓄电,而在市电电源断电时断电检测和应急启动模块可检测到断电信号,此时蓄电模块对断电检测和应急启动模块供电,断电检测和应急启动模块又对第二照明模块供电,从而使第二照明模块能够在市电电源断电时正常照明。本实用新型提供的LED照明应急灯的结构简单,而且稳定性较好,能够采用蓄电模块以正常电压供电照明。
附图说明
图1为本实用新型提供的LED照明应急灯的电路方框图。
图2为图1中的LED照明应急灯电路原理图。
具体实施方式
如图1、图2所示,本实用新型提供的LED照明应急灯包括市电电源、降压模块1、整流稳流模块2和第一照明模块8,还包括断电检测和应急启动模块5、第二照明模块3、驱动模块6和蓄电模块4,市电电源分别连接降压模块1和驱动模块6,降压模块1又分别连接断电检测和应急启动模块5和整流稳流模块2,整流稳流模块2连接第一照明模块8,断电检测和应急启动模块5连接第二照明模块3和蓄电模块4,蓄电模块4又连接驱动模块6。在本实施例中,蓄电模块4配置有蓄电保护模块7,蓄电模块4通过蓄电保护模块7连接驱动模块6,蓄电保护模块7用于控制输入电源的电压。
下面详细介绍各种工作功能状态:1、市电电源正常供应电源用于第一照明模块8和第二照明模块3照明时,路径A、市电电源经降压模块1、整流稳流模块2对第一照明模块8供电;路径B、市电电源经驱动模块6对第二照明模块3供电。2、市电电源正常供应电源用于为蓄电模块4蓄电时,市电电源经驱动模块6和蓄电保护模块7对蓄电模块4充电。3、市电电源断电时,断电检测和应急启动模块5检测到市电电源断电,启动蓄电模块4,使蓄电模块4经断电检测和应急启动模块5对第二照明模块3供电,用于照明。
