[讨论]征求DIY自行车车灯的建议
<P>小弟在考虑DIY自行车用的前灯的</P><P>现在初步计划如下：</P>
<P>电源采用4AA，电压6V。电源做成独立的，放在后座包里面，电源线经车身引到车把。</P>
<P>电路采用DC/DC降压模块，配恒流驱动。</P>
<P>灯头采用单颗 3W LED。</P>
<P>目前问题是：</P>
<P>灯头的外壳和反光碗目前没头绪，买成品车灯拆来用代价太高了。自己DIY难度很大，缺工具少材料。</P>
<P>用普通手电筒的灯头改，又不方便，因为省略了电池的部分，后面又要固定，又要引线，还得尽量防水，难度比较大。</P>
<P>开关的安装不知如何处理，安装在车把上，引线多，而且防水不好处理。感觉如果能装在灯头上最好。</P>
<P>电路比较昂贵，但是用3AA接7315的话，3W恐怕坚持不了多久。另外电路是否需要调光/闪光等乱七八糟功能？</P>
<P>不知各位有何建议？</P> 弄个小手电绑在头盔上
回复：（xiayutian）弄个小手电绑在头盔上
<P>这个有两个问题：</P><P>一是小手电亮度和持续时间没法保证，手电大了放头盔上又太重。</P>
<P>二是手电的光线随脑袋转，和车友同行的时候，转头看别人很容易把别人晃了。黑夜里被强光线迎面照一下，紧接着的几秒钟甚至更长时间几乎处于失明状态，太危险了。</P> <P> <BR>底座是报废的POWER BEAM</P> 要持续时间长的话,多备几节电池 <P><BR><BR><BR>也不是很重</P>
<P>换上LOP的话就更轻了</P> <P>呵呵，头盔上那个像激光武器</P>
<P></P>
<P>其实用6V电源有个原因：</P>
<P>我在电子城看到一款小型6V蓄电池，重量比两节1号多一点，如果我用6V电源，以后就可以兼容这种蓄电池，而且电源和灯头分离的做法也很容易把灯头改做其他用途。</P>
<P>顺便：你的头盔很帅啊，我的都旧的不行了，有一次摔在树丛里面，外面的塑胶壳戳了一个洞。</P>

led一样安全的，1月份骑了十多天，每天至少2个小时夜骑，最多的一天5个多小时
用的mzzlg，卡在山地前轴上方，路上玻璃铁丝石头一目了然。
