改造了个廉价的1AAA锂电1W

jhbhb

<P>材料：18元的国产1AAA，韩国的1WLED，一段黄铜管。韩国的1W从底板上拆下来后发现原来的正极引脚没用，正极跑到LED的底上去了，放砂纸上磨了一下底座，好像是铜的。直接把LED焊到黄铜管上，散热不用担心。<img src="attachments/dvbbs/2005-9/200592219523371258.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/2005-9/200592219523371258.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592219535439346.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/2005-9/200592219535439346.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592219543462073.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/2005-9/200592219543462073.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592219553262819.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/2005-9/200592219553262819.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592219562516241.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/2005-9/200592219562516241.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>加了一个1.2欧的电阻，4V时刚好350mA</P><img src="attachments/dvbbs/2005-9/200592219584614964.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/2005-9/200592219584614964.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/20059222005540795.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/2005-9/20059222005540795.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>右边是加了7135的1W小镁对比光斑，小镁的聚光好一些。不过要是对这天花板看房间内的亮度两支却差不多。

楼主改的小镁非常好！我用的很爽！

这支就便宜了，成本只要50多元。而且因为是开关尾盖，做起来更简单。

<P>第三张照片LED咋看有点气泡呢？</P>[em07]

jhbhb

气泡可能是反光吧，实物上没有

<P>这个我也有。上次转东西时，送给那个朋友了。忘记是谁了：）和合</P>

我烫坏过两个了，所以知道该怎么焊才不会烫坏，电烙铁温度一定要高，外面这一圈要一个毫米一个毫米的焊，焊完一个点要等冷却了再焊下一个点。

<P>忘了问反光碗效果和小镁的比起来如何？</P>

jhbhb

<P>小镁的好，不过可能跟用的LED不一样有关系，韩国的LED发光点比较大，所以不是很聚光，但亮度还是有的。</P>

LZ的18元的国产1AAA哪买的？看样子好像是仿美光的？灯泡的？

jhbhb

韩国的LED只是一片带散热底板的LED，没有筒身的。

上面那个是对比的小镁
