I just found out today that repairing LED lights does not require a soldering iron or electricity, and the method is better than a heating table [I love electrical repair]
有智慧!
其實不推薦這種辦法:1. LIght Emitting Diode (LED) 有分正負極(Anode/+ 和Cathod/- 極)區別方法是看電路板PCB 上的標示”GND”. 2. 用打火機燒很容易燒壞LED. 商用半導體零件工作溫度約70度C, 而軍用規格也只有125度C. 3. 不易集中火力,也會解焊其他的零件,如影片中所示。It is not professional!!
燈泡是220V~請問能改台灣110V嗎
那灯珠要怎麼分正負
敢问,灯珠不分正负极吗?
LED就是二極體, 有正負極。
用万用表打到测通断档,用表笔测,如果灯珠发亮正负正确,反侧就不亮,正反测都不亮就是灯珠坏了。
直接短路不就好了
還以為先你燒紅手上的工具
这是没有正常的工具和不是技术人的做法!!
好的
