LED组灯为何不亮
LED摩托车自制刹车灯,美观节电用三年了,最近经常出现个别不亮或不太亮,先后换了十耒个了,经检查电源是好的,我还在电源串了三只二极管使供电不超过12伏,结果同样出现个别不亮或不太亮,本耒LED寿命长,不知怎么啦?请高手指导.500) {this.resized=true; this.width=500; this.alt='这是一张缩略图,点击可放大。\n按住CTRL,滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/50/1171762583.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
