Description

充电式交直流两用灯泡
技术领域
本实用新型涉及一种充电式交直流两用灯泡，尤其是一种用于照明的LED充电式交直流两用灯泡。
背景技术
现有技术中的LED照明灯泡，均只能使用交流电作为电源。当交流电停止供应时，只能用应急灯照明。但普通家庭一般都不购买应急灯备用，因而只能转而使用蜡烛。由于现代科技的发展，所需使用的电器越来越多，能源危机已成为全世界共同的难题，各地常出现电力供应不足的情况，用电高峰期停电的频率也越来越高，因此给人们的生活带来诸多不便。
本实用新型内容
本实用新型的目的在于克服上述缺陷，提供一种充电式交直流两用灯泡。
为了达到上述目的，本实用新型
由于采用了上述方案，本实用新型可同交流供电的普通节能灯、白炽灯一样广泛使用，并实现了直流备用照明。同时本实用新型灯体小巧，高效节能，使用寿命长。
附图说明
图1为本实用新型结构的分解图；
图2为本实用新型的电路图。
具体实施方式
如图1中所示，本实用新型的灯泡与普通灯泡的结构大致相同，灯头7的下端连接了塑料外壳8和透明外罩15，其内部为封闭的腔体，设置有线路板9、发光体11和反光纸14。但其内部设置有与线路板上的工作电路相连接的充电电池6和充电指示灯13，在外壳上还设置有开关10。
如图2中所示，本实用新型的工作电路由充电电路1、蓄电池6、过充保护电路2、交直流供电转换电路4、过放保护电路3和照明电路5等部分组成，它们的组成及连接均与常规的电路相似。
充电电路1主要由充电接头AC-2、AC-1、电容C1、C2、电阻R1、R2及桥式整流线路D1-D4组成。经由AC1、AC2而来的交流电，经电阻R1、R2的分流及电容C1、C2的分压后，提供约220mA的电流，经D1-D4整流后，向电池6提供直流电压。
过充保护电路2主要由三极管Q1、二极管Z1及电阻R4-R6组成，当电池6充满。电压升高，Q1导通，R4放电，充电电流下降以保护电池。充电指示灯LED11与电阻R7串接后也连接在电路的两端，起指示作用。
过放保护电路3主要由三极管Q2、Q3、二极管Z2、电容C4以及电阻R10-R13组成。当电池电压降低，Q2、Q3截止，发光二极管LED1-LED10熄灭，电池不再放电，保护电池。
交直流供电转换电路4由开关SW1、二极管D7和电阻R9组成。当开关在AC状态，直接向照明电路的发光二极管LED1-LED10供电，不耗损电池电量；当开关在DC状态时，D7使Q2截止灭灯，停电时R9使Q2、Q3工作，自动亮灯。
