<P>照在墙上原本是方的不是现在看到的圆的 但是效果和普通透镜比超级好,能射100米 普通透镜只能射30米最多了 哈哈 把这个用在大家的小型手电筒上我个人认为很完美 至少灯头直径可以缩小不少(此透镜的直径只有15mm)<br></P>

<P>能把透镜照个图,看看样子吗?  为什么会超级好,能射100米 普通透镜只能射30米?  是聚光角度小吗? </P>
<P>那里有买的?  15mm好!  就是想找小点的.  </P>

是不是只有LED用透镜才有效果？

ajianzhangfan

<P>上个图看。</P>

killerwc

100M别的透镜也能做到啊，你要描述100M后的效果，如果只能看到一点点影子，别的透镜也能做到

<P>大家有什么问题 就加QQ116790367 漫漫聊 在这里聊太慢</P>

老沈

咱没有也不会QQ啊.

问多星

<P>再上几个光斑图 都是用透镜的 从上至下分别是25度 15度 10度</P>

这个透镜直径是15mm,最厚处约多少?  距LED约有多远?   咱自己用透明片做一个.

<P>直径15的能射100M,真的吗,不怎么相信啊</P>

diantong

<P>关键是发射角度，如果能搞到小于1度的杯子或透镜，射200m也不稀奇，那个maxabeam的特点就是反光杯的发射角度小。</P>
<P>不过发射角度太小也不好，象激光一样，结果照明面积小，反而不好用。再说LED手电光通量普遍较小，光束的穿透力又不强，就算照到100m外估计也看不清楚了。</P>
<P>要玩远射程还是上探照灯吧。</P>

咱一个月前就备好了透明片了,最厚的才10mm.  老想着磨一把刀,夹在台钻上出毛坯,再用磨料抛光(也用台钻).虽然没试过,应该行得通.  手电透镜比放大镜要求应该低多了.   就是曲线要找本书出来看看.....

问多星好: 咱还没有私聊的习惯,大多在帖上说.隅而用短信.

老沈，你好人家太厉害了，佩服佩服

<P>我现在有这样的要求,使用1W或3W的LS,光杯直径在30VMM之内,150M处我要看到事物;不知能否实现</P>
