5mm的或者10mmLED散热不好,光衰严重,用上这类LED不如不用!

Rex 发表于 2009-10-13 19:55

回楼上的,5mm能有多热,寿命比大功率的长多了~~~ 不能一概用大功率的概念套到所有LED上去!应该按实际用途选择适合的LED,并不是什么场合都适合用大功率的。打老鼠你会用7.62x39吗?!

回楼主:如果是配合工具使用,比如说像BOSCH(博世)那个带LED的电钻那种情况,一般最多3~5个5mm就足够了,估计你的设计都是小体积的,电池电量有限。

貌似用草帽头的比较好,配上LED光杯,就工业面板上那种常见的指示灯光杯,做成附带在工具上照明装置。必须限制照明角度,不然人家在操作工具时太炫目。
