[原创] Zenix IQ 1w改3W
<P>刚买Zenix IQ头灯,直接拆开看,用的是luxeon的Q bin 1w</P><P>直接拆了换 3w ,<IMG src="http://218.201.33.53/wgbbs/UploadFile/2005-9/200591223773643.jpg"></P>
<P>左边是3W HighDome 右边是1W LowDome</P>

原来的电流是多大?用3W的话不是要改大电流? 亮点了吗?这个是恒流的呀。 不改电路,直接换3W有何意义啊!!散热应该也不会有问题了,呵呵!! 关键的被删了,楼主PM我删掉的东东:) <P><IMG src="http://218.201.33.53/wgbbs/UploadFile/2005-9/20059210592448811.jpg"></P>
<P>DIY的全铜散热片 这个东西着实让我忙活了半天</P>

<P>买回来就拆</P>
<P>顶</P>
<P>顶</P>
<P>原来电路恒流 300ma 左右 </P> <P>这个透镜直接上1W的RXOJW HD光斑如何?</P> <P>另,为什么楼主的ZENIX IQ是2AA的呢? 国内都是3AAA的,我一直很想搞个2AA的ZENIX IQ</P> <P>IQ应该是 2AA的,要不升压电路不就只起恒流的作用了吗?</P>
<P>HD的聚光没有 LD的好,不过我喜欢闪得开的的光线</P> <P>极限600mA * 3.5V = 2.1W 不够3W不过考虑散热,暂时将就了</P>
<P>主要是这个新片封装好 SOT-23 手工可焊接</P> <P>电路不好做啊</P> <P>楼主,</P>
<P>把你的1W给我吧。</P>
