Description

一种高亮度发光二极管应急灯
技术领域
本实用新型涉及一种应急灯,特别是一种高亮度发光二极管应急灯。
背景技术
目前随着对公共场所的消防及安全的标准的日益提高,越来越多的建筑物中需要安装应急灯,以便当发生停电时可以应急照明,现有的应急灯一般采用节能莹光灯或白炽灯发光,但是由于节能莹光灯或白炽灯发光一般需要较大的功率才能点亮,因此造成应急灯需要较大的蓄电池,且节能莹光灯或白炽灯的使用寿命较短,长期处于待机状态的节能莹光灯或白炽灯,有可能在发生火灾或停电需要应急灯照明时而无法点亮。
发明内容
本实用新型的目的是解决现有技术中应急灯使用节能莹光灯或白炽灯所存在的对电源有大功率输出的要求及使用寿命短的问题,提供一种功耗小、使用寿命长的高亮度发光二极管应急灯。本实用新型设计一种高亮度发光二极管应急灯,包括壳体、蓄电池、开关、充电电路、驱动电路,其特征在于:驱动电路连接高亮度发光二极管阵列。高亮度发光二极管阵列由多个高亮度发光二极管并联构成。蓄电池由三节可充电的干电池串联构成。本实用新型的优点是功耗体积小、使用寿命长,能满足应急灯的安全需要。
附图说明
下面结合附图和实施例对本实用新型作详细说明,
附图1为本实用新型的连接示意图,
附图2为本实用新型的蓄电池连接示意图,
具体实施方式
图中包括蓄电池1、开关2、充电电路3、驱动电路4,其特征在于:驱动电路4连接高亮度发光二极管阵列5。高亮度发光二极管阵列5由多个高亮度发光二极管6并联构成。蓄电池1由三节可充电的干电池7串联构成。发光二极管的功耗较小,因此在用于应急灯照明时能最大程度地减少电能的损耗,一般仅为同等照明白炽灯或莹光灯功耗的10%——30%,由此可以适合于超小型的蓄电池1,即由三节可充电的1号、2号、5号及7号干电池组成蓄电池1使用,可以将应急灯制作得非常小巧,适合于家庭等各种不同场合使用,而且高亮度发光二极管6的使用寿命一般在几万小时以上,能满足免维护的使用要求,使用时,电网的电力经充电电路3对蓄电池1充电,当断电时,蓄电池1放电由驱动电路4转成3V左右的直流电,直接供给高亮度发光二极管阵列5使用。

Claims (3)
