所需的电筒为AA电池盒：(记得带开关的！)

为了大电流的电感，暴力拆下日光灯的E形磁芯，
只用一边E字，在中间(用粗铜线)绕制16圈：

焊接好电路板：(8050为3个并联，电容为390pF)

楼主成功了吗？亮度如何？

用万用表10A档，
测电池输出电流为0.34A。
LED微微发热。

哇，厉害，这个DD做应急灯应该不错，
对了，难那个灯也拆的太厉害拉，哈哈
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

光斑：(用过1W的朋友不要期望有多亮，光线比较散，适合DIYer)

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

我拆磁芯时，
用镊子镊住，
然后用打火机，
慢慢地烤，
就可以拉出来。

好啊!赞一个!

sjb3658 发表于 2005-9-14 03:51

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

ttheone 发表于 2005-9-26 19:33

输出电压有几伏？
能推动1－3w led否？

sjb3658 发表于 2005-9-27 03:49

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

黄师父 发表于 2005-9-27 19:25

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。

kendall 发表于 2005-9-28 01:54

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!
