Description

一种停电自动延时的LED球泡灯
技术领域
本发明涉及一种停电自动延时的LED球泡灯。
背景技术
城镇中经营的一些门店,如城镇中的超市、酒家,还有学校学生晚自修等,当晚上碰到突然停电时,会给用户带来很大的麻烦;还有天灾的地震灾害,造成公电设备已被破坏,会给逃生带来困难。
发明内容
本发明一种停电自动延时的LED球泡灯,公开一种晚上碰到突然停电事故时,LED球泡灯能自动延时约一个小时,方便当场工作人员处理突发事件。
一种停电自动延时的LED球泡灯,其电路结构由阻容降压电路、整流电路、滤波和稳压电路、备用电源电路、充电电路、防过充电电路、防反充电电路、防过放电电路和LED发光电路组成。
附图说明
附图1是一种停电自动延时的LED球泡灯的电路原理图。
具体实施方式
如附图所示,R1、C1或R10、C3组成阻容降压电路,把交流220V电压降低若干伏后送到整流电路B1或B2,然后又整流电路把降压后的交流电变成脉动的直流电送给滤波电路C2和稳压电路D2或D7。
如附图所示,备用电源电路有可充电的电池E组成,它周围有充电电路B2、D6和防过充电电路D7;防反充电电路由D1、D6组成,它可以防止当电源消失时,备用电源向充电电路反充电;防过放电电路由IC、D4、R2、R3组成,IC是型号为TWH8751的IC芯片,D4是稳压二极管,选用稳压值为2.4V,R2、R3组成串联的分压电路,当备用电源放电过程中是电池的电压降低,当电压降低到使分压电路的R3端电压低于2.4V时,IC的5脚失去驱动电压而使IC由导通变为截止,从而关掉LED球泡灯,起到防过放电作用,保护电池过放电而损坏电池。
如附图所示,IC右边的LED是发光二极管电路,选用3串6并电路,功率约为9W,如蓄要大的功率或小的功率时,可以采用增加并联支路或减少并联支路的方法实现。为了减少LED球泡灯的工作电流,减少球泡灯的发热量,选用5730或相灯功率的LED芯片。
如附图所示,V是压敏电阻,在电路中起瞬间过电压保护作用,D5是整流二极管,在电路中起充电宝护作用,D3也是整流二极管,在电路中起到引导和隔离市电电源的LED工作电源对电池充电。
