一个投射系统很独特的小手灯
<P>主要目的是介绍投射系统。</P><P>贴哪里呢？还是放在收藏展示吧。</P>
<P>以前有过零星介绍，现在有空儿上个图。</P>
<P>AAAX2，方形，米泡，打火机大小，其投射系统很别致。</P>
<P>正面是直径35mm微凸同心圆，原本以为是费涅尔透镜，拆开一看，同心圆当中是一小凸透镜，外面一圈圈棱不是透镜而是反射镜！！利用全反射原理，就象望远镜里棱镜的原理一样。这样光源可以离镜片很近，微凸的镜片可收集大於180度内的光线。另外后面是半球形反光碗，反射后光线进入镜片的角度与光源是一致的，效率很高。</P>
<P>这么一个小阿扁，亮度出乎我预料。</P>
<P>(美国专利，中国制造)。</P>
<P>这投射系统光源离镜片很近，用于大功率灯泡因发热可能不行，但大功率LED一定不错。制造也不太麻烦，塑料，开模。</P>
<P>哪位能人来仿一个吧。</P><br><img src="attachments/dvbbs/2005-7/20057116182692071.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/2005-7/20057116182692071.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-7/20057116184836155.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/2005-7/20057116184836155.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-7/2005711619945349.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/2005-7/2005711619945349.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-7/20057116194296401.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/2005-7/20057116194296401.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-7/2005711620650576.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/2005-7/2005711620650576.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>

<P>里面的铝箔是我放上去的，加强反光。<BR></P> <P>楼主,你照片里背景里的书本是啥? 看上去也很有吸引力呀</P> 光斑图呢？最好来个对比。 <P>不是书，是Au Vieux Campeur 的 catalogue。</P>
<P>光斑对比没大意思，来两张吧。两个7号电，这样就不错了。</P>
<P>距离：床上，天花板。左边是不满电3W。</P>
<P>主要是投射系统很特别，其他的电筒头灯为什么不用呢？</P>
<P>不复杂，效率也高。</P>
<P>不过前几天看到Petzl 的TIKKA XP头灯，投射系统也是一圈圈的，但不是inova那样的，是平的。不知是不是。</P><img src="attachments/dvbbs/2005-7/20057125354327712.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/2005-7/20057125354327712.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR><img src="attachments/dvbbs/2005-7/20057125361739156.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/2005-7/20057125361739156.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR> <P>我是说仿这个投射镜用于大功率LED，不是仿这电筒。</P>

<P>这个小手灯多少钱啊?</P> <P>谁能告诉我哪有卖的?卖多少钱吗?</P>
<P>谢谢啦</P> 是在巴黎买的。 <P>买......买......买不起</P> 不好看啊，也感觉不那么SHUANG！ <P>可以用来做一个用1Wled的超薄型手电，采用塑料外壳，随便找块手机上的锂电池就行了，续航2小时以上</P>
<P>就是没有这种透镜</P> <P>这小东西不错啊,多少米啊?合成人民币的话?</P> <P>爽啊 </P> 顶起，问多星的扁形手电设计是不是可以参考一下这个？

是用的菲涅尔透镜吧?好创意! 太帅拉 就是买布道
