看看我改的2AA镁光

sun1975

<P>等待NG山娃实在难熬,手又庠庠,就把前些天从网上收来的2AA镁光改了,大家"表"笑我,照葫芦画瓢...............</P>
<P>驱动电路还是用美信的,MAX1674。光斑对比是与L1P的，L1P满电，镁光用相机用完的旧电池。 后面的表是个效率，配合稳压电源测出来的，不知合理不合理</P>
<P>这是灯头部分最后完工的图, 过程没有留下照片  :(</P>

明白了，靠LED底座把那个东西压下去，这样电路断开，不过这样的话，有可能把LED拧坏啊

开关那个地方是怎么处理的？原来是拧头部当开关的，现在头部没了？

<P>
<P>保留了原来的开关方式，LED及驱动部分直接放进去替代原来开关组件。实际上这样换电池的时候可能会掉出来，所以里面还加了“O”圈。</P>
<P>磨好的反光杯底部的孔是小于LED外面那一圈黑色塑料的。</P>
<P>上一个头部图，可能会看的清楚一点：<img src="attachments/dvbbs/2005-8/200582220182545731.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/2005-8/200582220182545731.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /></P>
<P>这样会不会更好看一些：<br><img src="attachments/dvbbs/2005-8/20058222036172520.gif" 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/2005-8/20058222036172520.gif\');}" onmousewheel="return imgzoom(this);" alt="" /><br></P>

有没有可能把电路改到1AAA的小镁里面，我看也有0.32到0.75W的功率了。

sun1975

<P>电路塞到AAA小镁是可以的,只是AAA电池用这么大电流放电撑不住的，而且AAA电池内阻也大，用这个电路使用1AAA电池供电的话，LED端电流只有200mA左右。</P>
<P>这个电路的效率与LED的BIN有很大关系，电压越低那个表格后面的效率会越高，我测试的时候用RXOJ的LED，最后安装时使用了RWOH的LED，不一样的。</P>

<P>我想问了一下，电池用什么电池，可以用多长时间？</P>
<P>还有，原装的灯碗能行吗？会不会烤坏？</P>
<P>最后一个问题，聚光性能怎么样，亮度跟以前比怎样？</P>

<P>普通AA碱性电池或AA充电电池,使用时间与电池类型、容量有关，碱性电池高亮一小时没有问题吧，低亮时间会更长的，只是用充电电池的话要注意过放问题，当然如果您自制的时候使用了IC的电量检测功能就没有问题，我没用。
<P>用原来的碗就可以，不会烤化的，不过要注意LED的散热。
<P>聚光不错，亮度嘛，比原来的小灯炮强多了，比小P亮（当然这么比不科学），我贴那个光斑时用相机用完（不能开机了）的碱性电池，相当不错。</P>

<P>兄弟，我看了一下LED的参数，你用的是1W的吧，它的工作电压是3。3V，电流为300MA左右，如果用两节AA的充电电池，1。2Vx2=2。4-2。5V能点亮吗？</P>
<P>谢谢您的回复！</P>

这款LED右图的中脚有焊过的迹像，感觉不像真的：）
