通常3W电子节能灯电子镇流器电源整流电路均采用桥式整流电路,其实采用半波整流电路同样可以正常工作.或许有人认为这样节能灯供电不足会出现灯闪烁现象,实践证明使用此电路的3W节能灯在AC170V-240V时能稳定地工作(使用2U灯管),若使用3W螺旋灯管效果会更好.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/38/1138973407.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
