手中没这种设备，本来想测实际使用时间，谁知道不小心把LED弄坏了，点亮的时候把反光碗拧了下，而却那个反光碗是刚好套住LED的，LED还有，因为是把底座弄小了，所以不想再换一个了，这个电路是放在5LED的桶身里的，以下改造实物<img src="attachments/dvbbs/2005-9/200592522341293987.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/2005-9/200592522341293987.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR><img src="attachments/dvbbs/2005-9/20059252235358908.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/2005-9/20059252235358908.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR>

淘宝有。

<P>这是两个电路并联的。</P>
<P>2AA时，驱动效果好点。。。。。。</P>

8505淘宝有整套的买，效率等有空再测试下，如果做2AA的1W 不错，1个8505就够，也很便宜
