受教于分隔符老兄的精华帖,决定自己也动手做个3W小镁,3W小镁是做成了,用电烙铁直接把led焊在铜座上,散热是很好,不过想想就10440这么点电,3W还不一下把它榨干了.而且小镁这么小的反光碗,也限制了3W的发挥.刚好手上又到了sajia帮代购的7135,把7135和1Wled和小镁组合在一起,应该可以有更长的使用时间,亮度也够了.<img src="attachments/dvbbs/2005-8/20058141103188496.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/2005-8/20058141103188496.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>先对铜座进行再加工,中间的孔是自己手工打的,在铜座的大头面靠边上一点钻进,小头面从中间出来.再把大头面用3mm圆头旋转合金锉切削出如图中凹陷.<img src="attachments/dvbbs/2005-8/20058141163777892.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/2005-8/20058141163777892.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>把7135直接焊在铜座上<img src="attachments/dvbbs/2005-8/2005814119421936.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/2005-8/2005814119421936.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>焊上导线和正极板,铜座的小头面有焊锡,是因为我想把1Wled也焊上去,在焊坏一个led后放弃了.小头中间涂点硅脂,边上在用AB胶粘和,强度足够,而且有了7135限流,led温度也不高,散热不成问题.<img src="attachments/dvbbs/2005-8/200581411133829341.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/2005-8/200581411133829341.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>正极板和铜座空隙出填满703硅橡胶,再套上热缩管缩紧.<img src="attachments/dvbbs/2005-8/200581411171798990.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/2005-8/200581411171798990.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>小镁头部用磨光机磨平,内部跟铜座接触的位置涂上导热硅脂.<img src="attachments/dvbbs/2005-8/200581411193217264.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/2005-8/200581411193217264.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>粘上led,焊好导线就完工了,反光碗还要另外加工
