<p>30mw 532 手电,用普通的 16340 电池 大约能照射多长时间?&nbsp; </p><p>还有就是他和 200mw 650&nbsp; 哪个目视亮度高一些，大约能照射多远，晚上是否能看到光束，</p><p>谢谢了。&nbsp;</p>

LEDLASER

<p>1.50mW的约440mA,30mW的应在略小于300mA吧，(功率越低效率越低）用600mAh的16340能用两个多小时。</p><p>2.同样的辐射功率，532nm的绿光是650红光的8倍。因此532,30mW&gt;650,200mW</p>

就容量/价格比而言，用18650最好。

LEDLASER

激光手电，我想没有人能玩1个多小时。50mW以下的激光用16340足够了，过大的电池容量只能增加体积，减弱便携性。

<p>30mw 532，一般采用300mW左右的<span lang="EN-US" style="font-size:10.5pt;font-family:&amp;quot:;quot:;mso-bidi-font-size:12.0pt;mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><span style="mso-spacerun:yes">&nbsp;</span>808nm pumping。电流不超过350mA。</span></p><span lang="EN-US" style="font-size:10.5pt;font-family:&amp;quot:;quot:;mso-bidi-font-size:12.0pt;mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa"><p><span lang="EN-US" style="font-size:10.5pt;font-family:&amp;quot:;quot:;mso-bidi-font-size:12.0pt;mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa">如果晶体效率低下，为了得到额定的绿光输出，只有增加LD的功率。电流就更大了。</span></p><p><span lang="EN-US" style="font-size:10.5pt;font-family:&amp;quot:;quot:;mso-bidi-font-size:12.0pt;mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa">600mAh的16340撑不到两个小时。CR123A容量大概<span lang="EN-US" style="font-size:10.5pt;font-family:';quot:;mso-bidi-font-size:12.0pt;mso-fareast-font-family:宋体;mso-font-kerning:1.0pt;mso-ansi-language:en-us;mso-fareast-language:zh-cn;mso-bidi-language:ar-sa">700mAh，撑两个小时困难，估计也撑不到两个小时。</span></span></p></span>
