该电路基板1设置有第一桥式整流电路3与第二桥式整流电路4,第一桥式整流电路3设置有四个连接的二极管D1、D2、D3、D4,且二极管D1、D2与二极管D3、D4的连接方式相反,使二极管D1、D2之间以及二极管D3、D4之间形成有一组第一负载节点31,而二极管D1、D3之间以及二极管D2、D4之间形成有一块第一电源节点32;第二桥式整流电路4设置有四个连接的二极管D5、D6、D7、D8,且二极管D5、D6与二极管D7、D8的连接方式相反,使二极管D5、D6之间以及二极管D7、D8之间形成有一组第二负载节点41,而二极管D5、D7之间以及二极管D6、D8之间形成有一组第二电源节点42,且第一电源节点32与第二电源节点42为呈并联状;该二极管D1、D2、D3、D4、D5、D6、D7、D8可为稳压二极管,如基纳二极管(Zener diode)。The circuit substrate 1 is provided with a first bridge rectifier circuit 3 and a second
该发光二极管模块2设置有以多个发光二极管所串接形成的第一发光件21与第二发光件22,第一发光件21连接于第一负载节点31,而第二发光件22连接于第二负载节点41。The light-
通过上述第一电源节点32与第二电源节点42输入一交流电源(如:110V交流电源)时,使得第一桥式整流电路3在工作时,同时有两个二极管D1、D4导通以及两个二极管D2、D3截止,或是两个二极管D2、D3导通以及两个二极管D1、D4截止,让第一发光件21上的输出电压维持相同的极性,进而得以使第一发光件21运作;而第二桥式整流电路4在工作时,同时有两个二极管D5、D8导通以及两个二极管D6、D7截止,或是两个二极管D6、D7导通以及两个二极管D5、D8截止,让第二发光件22上的输出电压维持相同的极性,进而得以使第一发光件21运作。When an AC power supply (such as: 110V AC power supply) is input through the first
