为什么没有黄色的LED灯
很多LED其实不比白炽灯暗,但因为光色的原因总显得没有白炽灯亮,为什么不能把光色做的和白炽灯一样呢? 有黄色的,不过比白的效率更低 <P>我有黄色的 1w led 灯</P><P><img src="attachments/dvbbs/2004-7/2004731201330481.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-7/2004731201330481.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /></P><P><img src="attachments/dvbbs/2004-7/2004731201424233.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-7/2004731201424233.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />亮度不错吧,绝无己有f </P> 本帖最后由 说话的蛋糕 于 2018-4-2 11:37 编辑
黄光有的,只不过你没有买啊,现在很多3400K的灯珠啊,黄光即低色温的LED,显色好,比白光暗,LED卖点是亮,所以商家只能大批量的卖白光,没有卖点商家还怎么忽悠,有多少老百姓会懂,一般内行都玩3400K--5000K的色温 说话的蛋糕 发表于 2018-4-2 11:34
