简介
LED 灯泡由许多串联的小型 LED 组成。一旦其中一颗 LED 烧毁,电路就会断开,整个灯泡也就无法工作,尽管大部分 LED 其实仍处于良好状态。
本指南教你如何修理烧毁的灯泡:只需用一颗新 LED 替换烧毁的那一颗,闭合电路,电流就能再次流通,从而点亮灯泡。

I have a large LED bulb with 8 banks of LEDs. The bulb would flicker at times then stay illuminated for a period. After a short time doing this it would completely stop then come back on. It finally stopped working at all. I engineered myself a couple leads from some old multimeter leads I had collecting dusk. I attached those to a fresh 9v battery then checked each bank of LED. All illuminate as quickly as I touch the leads to the first LED in each bank. What’s the issues with this bulb? It’s not due to a bad LED and breaking the continuity. I also prior to testing with the battery went through each bank getting a solid tone so there’s no loss of power from ATo Z. I’m open to suggestions based on your experience tackling this issue. It’s my first rodeo with the LED bulb. Thanks for your help.
