[原创]自制7135X2恒流驱动假3W-led
<P>因为近期到了一批可以直接焊7135的铝基片，加上手上又有一片3W的led和其他的一些配件（呵呵，有利条件）所以一直想把自己的那个已经睡觉的强光灯炮的手电给利用起来。</P><img src="attachments/dvbbs/2005-11/200511101423079221.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/2005-11/200511101423079221.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR> <P>此手电的反光杯和前面的镜片买来2天后就over了，因为这种灯泡发热量巨大，先溶镜片，再溶了反光杯，最后自己也溶了…汗！-_-（为什么灯泡不先溶呢？！）现在基本强光灯炮的都用金属的了。 </P><img src="attachments/dvbbs/2005-11/2005111014242062808.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/2005-11/2005111014242062808.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR><img src="attachments/dvbbs/2005-11/200511101425280960.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/2005-11/200511101425280960.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR> <img src="attachments/dvbbs/2005-11/2005111014332117349.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/2005-11/2005111014332117349.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR> <P>所以我要先搞个反光杯进去，可手上的反光杯大了这个电筒的直径好多，没问题，自己动手丰衣足食</P>

<P>不错啊,led固定再改进一下就完美了</P></DIV>
<br>恩，要想办法去攻个丝，这样就可靠性就大大提高了 <P>昨天请教了个朋友，朋友说铝也可以焊接的，只是要特殊的方法而已，让我先用他方法试试看，不行的话再去找亚弧焊，这样就不要攻丝这么麻烦了，今天一早起来牙也不刷就开始搞起来了，终于搞定，现在固定妥当了，呵呵！</P>

<P>铝很容易氧化，根本吃不上焊锡，所以焊的时候用功率大一点的电烙铁，把细铁屑粉加到松香里面去，把铝稍微打光一点，然后用焊锡在铝面上摩擦，铝一会就能吃上锡</P>
<P>不过我朋友说不是所有的铝都可以用这个办法的，具体什么铝他也没说，就先让我试试看，我试了，可以的！</P>
