可用在TEC40上的1W卡口LED灯泡

jhbhb

<P>材料：韩国的1WLED一个，卡口灯泡一个，热缩管一小段，铜接头一个，6.8欧电阻两个。铜接头粗细要套上热缩管后刚好塞进卡口灯泡座内。铜接头锯两段，适当打磨，LED从散热板上取下，底部在砂纸上磨出铜底，在把LED焊到铜接头上，两个电阻并联一头接铜接头，一头接灯泡尾部，因为韩国LED的底板是正极，所以铜接头不能直接套到灯泡座里面，而是隔了一层热缩管，灯泡座内涂了点导热硅脂。调节铜接头在灯泡座中的高度，让做好后的灯泡放进反光杯聚光最好，LED负极接上灯泡座外壳，用502胶水固定。</P><img src="attachments/dvbbs/2005-9/200592722321572752.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/2005-9/200592722321572752.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/20059272233184572.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/2005-9/20059272233184572.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592722333278386.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/2005-9/200592722333278386.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/20059272234867975.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/2005-9/20059272234867975.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200592722343563871.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/2005-9/200592722343563871.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>LED的光斑泛光比较亮，但中心亮度就差多了。照片是自动曝光。4节镍氢，电流340mA，点的时间一长，温度就比较高，手不能捏，3节碱性电流280mA，温度还好一点不知道镁光3D是不是也用卡口灯泡。2节大号电池电流40mA。

要看灯座了,塑料的就OVER

散热有问题，虽然LED的热量是传到铜接头和灯泡壳上了，但体积太小，340mA下估计时间长了塑料反光杯要烤坏。电阻用大一点电流控制在200mA左右应该没问题。

<P>ever led太贵了````</P>
<P>楼主做的这个好喜欢,但就是散热是个大问题.TEC 40都是塑料的,还不透气</P>

对解决散热问题大家有什么好办法

吓，如果上3W，T BIN，改成用在仿镁光4D上不是很好？用7135驱动，仿镁光都是铝座的，很好散热。
