A power supply node 32; the second bridge rectifier circuit 4 is provided with four connected diodes D5, D6, D7, D8, and the connection mode of diodes D5, D6 and diodes D7, D8 is opposite, so that between diodes D5, D6 and A group of second load nodes 41 is formed between the diodes D7 and D8, and a group of second power supply nodes 42 is formed between the diodes D5 and D7 and between the diodes D6 and D8, and the first power supply node 32 and the second power supply node 42 are connected in parallel; the diodes D1, D2, D3, D4, D5, D6, D7, and D8 can be Zener diodes, such as Zener diodes.

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-emitting diode module 2 is provided with a first light-emitting element 21 and a second light-emitting element 22 formed by connecting a plurality of light-emitting diodes in series, the first light-emitting element 21 is connected to the first load node 31, and the second light-emitting element 22 is connected to the the second load node 41 .

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 power supply node 32 and the second power supply node 42, when the first bridge rectifier circuit 3 is working, two diodes D1 and D4 are turned on and two One diode D2, D3 is turned off, or two diodes D2, D3 are turned on and two diodes D1, D4 are turned off, so that the output voltage on the first light-emitting element 21 maintains the same polarity, so that the first light-emitting element 21 operation; while the second bridge rectifier circuit 4 is working, there are two diodes D5, D8 conduction and two diodes D6, D7 cut-off, or two diodes D6, D7 conduction and two diodes D5, D8 When it is turned off, the output voltage on the second light-emitting element 22 maintains the same polarity, thereby enabling the first light-emitting element 21 to operate.

At this time, since the first power supply node 32 and the second power supply node 42 are connected in parallel, the first load node 31 It is connected in series with the second load node 41, so the diodes D2, D4, D5, and D7 between the first power supply node 32 and the second power supply node 42 will form a short circuit (as shown in Figure 5), and when the AC power input first When the power supply node 32 is connected to the second power supply node 42, two diodes D1, D8 are turned on and two diodes D3, D6 are turned off, or two diodes D3, D6 are turned on and two diodes D1, D8 are turned off, so that The output voltage flowing through the first light-emitting element 21 and the second light-emitting element 22 maintains the same polarity, thereby enabling the first light-emitting element 21 and the second light-emitting element 22 to operate, and because the first light-emitting element 21 and the second light-emitting element 22 are connected in series, which increases the voltage required for starting, so the first light-emitting element 21 and the second light-emitting element 22 will not be burned due to the increase in the voltage of the input AC power supply.

因此,本发明为可解决现有技术的不足与缺点,其关键技术在于,本发明利用第一桥式整流电路3与第二桥式整流电路4来分别连接由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,并利用第一负载节点31与第二负载节点41串联与否,来改变第一发光件21与第二发光件22启动时所需的电压,以让同一电路基板1上的发光二极管模块2可利用不同交流电源的电压启动,方便使用者使用。Therefore, the present invention can solve the deficiencies and shortcomings of the prior art. Its key technology is that the present invention utilizes the first bridge rectifier circuit 3 and the second bridge rectifier circuit 4 to respectively connect a plurality of light-emitting diodes connected in series. The first light-emitting element 21 and the second light-emitting element 22, and whether the first load node 31 and the second load node 41 are connected in series or not, to change the voltage required for starting the first light-emitting element 21 and the second light-emitting element 22, The light-emitting diode modules 2 on the same circuit substrate 1 can be activated by voltages of different AC power sources, which is convenient for users to use.
