    <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>
