<P>哇，厉害，这个DD做应急灯应该不错，</P>
<P>对了，难那个灯也拆的太厉害拉，哈哈</P>
<P>还有那个磁芯用开水泡一下就很容易拆的，我都那样拆的，哈哈</P>

<P>瞎忙了大半天，</P>
<P>使用中发现电筒的热量存在，</P>
<P>LED为较大的脉冲电流，</P>
<P>平均在1.2*0.34/（3.3*6）＝20.606060606060mA（没加入转换效率计算）</P>
<P>感觉该电路驱动8个LED以上比较合适。</P><br><br>

<P>我拆磁芯时，</P>
<P>用镊子镊住，</P>
<P>然后用打火机，</P>
<P>慢慢地烤，</P>
<P>就可以拉出来。</P>

好啊!赞一个![em17]

<P>我这里旧的日光灯比较好找，</P>
<P>很久没玩收音机了。</P>
<P>现在玩的是汽车里的收音头，（接12V，灵敏度高。）</P>
<P>楼上的朋友可以试一下收音机里的中频变压器，</P>
<P>本电路电流大，</P>
<P>最好用粗铜线，</P>
<P>反激式升压电路磁芯的体积大点好。</P>

<P>输出电压有几伏？</P>
<P>能推动1－3w led否？</P>

sjb3658

<P>该电路是市场上便宜的8LED电路，</P>
<P>无法驱动1-3W　LED，</P>
<P>感觉就是老沈的1AA-＞1W电路可以驱动。</P>

不错，我也做过几个这种样子的送人：不过用的是手机锂电加电阻。最长的已经使用1年半。价廉物美。全套10来元，充电一次连续用5，6小时没问题。[em01][em01]

<P>黄师父,能说说你是如何用手机锂电做的吗?家里正好有几个旧手机电池,正想拿来做手电或台灯,但总听说手机电池会爆炸,不敢乱用,小弟初手,请赐教!</P>
