光碗是2元小手电上的质量奇差，所以黄水没满，订购的透镜在路上，
相信换后有改善 <img src="attachments/dvbbs/2005-10/2005102111452427227.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/2005-10/2005102111452427227.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

不错啊，好像是用2aa的多头led改的[em07]

老沈 · 发表于 2005-10-20 07:04

1aa的5头也这样.直径20mm,最好再细点,外径16--17mm,就好了.

Elumin · 发表于 2005-10-20 18:12

14500 + 3W 是直驱吗? 应该有个小电阻吧!

jy500w · 发表于 2005-10-20 22:11

聚光如何啊，能达到多少米。

ttheone · 发表于 2005-10-20 22:17

如果能不破坏原来的多led灯头，互换使用就好了。

topsjb · 发表于 2005-10-21 01:53

太爽了，
好象是2AA电筒，
从中间截断，
加入3W，
聚光杯也够小的。

sjb3658 · 发表于 2005-10-21 14:38

楼主把过程说详细点，
好参照来改造。。。。。。。。

lklklk123 · 发表于 2005-10-21 19:53

详细就是把1AA5led的头去掉然后把led的散热片磨成直径17mm的
在背面引出正极电桶壳接负极
找个合适的反光碗或透镜前面加个CD保护壳塑料片OK了
对还有14500电池[em07]

sjb3658 · 发表于 2005-10-22 13:24

很小巧。。。。。

rxq · 发表于 2005-10-22 17:20

不错的DIY

uled · 发表于 2005-10-23 20:18

最好加点导热硅脂在铝板和电茼铝外壳接触处,以利用外壳散热

做得确实不错,可是……样子不是很好看，锯短的断端粗糙了一点，最好能够改善一下

问多星 · 发表于 2005-10-24 05:24

呵呵,不错就是反光碗和锯断的借口难处理除非有车床我也想用这个筒身做1AA1W的可就是没车床做的会不堪入目的呵呵正在想办法 ...

topsjb · 发表于 2005-10-25 03:38

打磨。。。。。。。

jhbhb · 发表于 2005-10-25 03:41

不用锯掉头部,把头部挖空,装上问多星的10度透镜,我想会非常合适.

topsjb · 发表于 2005-10-25 14:30

关注。。。。。。。。。。

pager · 发表于 2005-10-27 00:21

估计散热不理想，除非降低工作电流，呵呵
