Description

可充电LED灯
技术领域
本实用新型属于电子技术领域，涉及一种可充电LED灯。
背景技术
LED作为一种新的光源，应用的领域越来越广，在电源不稳情况下，不但容易造成LED灯的发光度不均匀，而且容易使得LED灯损坏，因此，有必要对现有的LED灯的驱动电路进行改进。
实用新型内容
本实用新型要解决技术问题是提供一种可充电LED灯，该可充电LED灯在电源不稳定时也能正常工作。
本实用新型为解决上述技术问题所采用的技术方案是：
一种可充电LED灯，其特征在于，包括整流器、稳压器、超级电容以及由二极管与电阻串联形成的发光支路；整流器输入端接交流电源，整流器的输出端接稳压器的输入端；超级电容与发光支路并联后接到稳压器的输出端与地之间。
所述的整流器采用MB6S型桥式整流器，稳压器采用7805芯片，超级电容采用深圳市三迈科技有限公司的5.5V/0.47F规格的超级电容器。
本实用新型的有益效果：
本实用新型采用超级电容进行蓄电，当电源电压不稳定时，由超级电容对LED灯供电，使得LED灯发光均匀，保持正常工作状态，且持续的供电能有效保障LED灯的使用寿命。
附图说明
图1为实施例1的电路结构示意图。
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步说明。
实施例1：
如图1所示，一种可充电LED灯，包括整流器、稳压器、超级电容以及由二极管与电阻串联形成的发光支路；整流器输入端接交流电源，整流器的输出端接稳压器的输入端；超级电容与发光支路并联后接到稳压器的输出端与地之间。所述的整流器采用MB6S型桥式整流器，稳压器采用7805芯片，超级电容采用深圳市三迈科技有限公司的5.5V/0.47F规格的超级电容器。本电路特点在于加上可以蓄电的电路部分，在交流6V-24V输入时候，后面LED灯能正常工作，且供电不稳的时候，LED灯也可以正常工作。
