Abstract

一种结构简单、成本低廉、使用寿命长的通用LED照明电路。技术方案是:包括桥式整流电路、LED灯,其特征是在整流电路与LED灯之间设置有滤波电路,LED灯为一列或数列并联连接的LED灯列,每一列LED灯由数个LED灯串联连接组成,LED灯为表贴灯或直插LED灯或LED管芯。

Description

通用LED照明电路
技术领域
本实用新型属于LED照明电路领域,尤其是一种通用LED照明电路。
背景技术
目前,常用的LED照明电路有两种结构,一种是由整流电路、恒流源装置和LED灯组成,另一种是仅由整流电路和LED灯组成,第一种电路结构造价高,影响市场推广,第二种电路结构的电流不稳定,影响照明效果和LED灯的使用寿命。
实用新型内容
本实用新型的目的是提供一种结构简单、成本低廉、使用寿命长的通用LED照明电路。
本实用新型的技术方案是:通用LED照明电路,包括桥式整流电路、LED灯,其特征是在整流电路与LED灯之间设置有滤波电路。
所述的LED灯为一列或数列并联连接的LED灯列,每一列LED灯由数个LED灯串联连接组成。
所述的LED灯为表贴灯或直插LED灯或LED管芯。
本实用新型的效果是:通用LED照明电路,在整流电路与LED灯之间设置有滤波电路。与设置恒流源的照明电路相比,由于减少了恒流源装置,因此本实用新型的照明电路能降低造价约30%,具有更好的市场推广价值。与整流电路直接控制LED灯的照明电路相比,本实用新型设置滤波电路,照明电路的稳定性更好,照明效果更好,同时LED灯的使用寿命更长。
下面结合附图和实施例对本实用新型做进一步的说明。
附图说明
附图是本实用新型的电路原理图。
