[请教]100mw532电筒里的808nmLD激光二级管是这样的吗?

<P><FONT size=5>一直搞不懂我的100mw532电筒里的那个所谓的LD到底是啥样,你门看在我的另一个贴子里拆过,但拆到下面那段实在是拆不出了(胶水沾的太死了),LD应该在下面那段里面,查了一下网上的资料,说是这种808管有mw级的,也有w级的,不知道我上面贴的图片是不是就是这电筒里LD的样子,另外我的电筒功率是100mw的,那么它的808管大概是多少功率的,看网上说是用1W的808管可pump出大于250mw的大功率532激光,不知我的电筒能否换上这种LD,另外就是看网上说808nm的管子的工作电压都是不超过2V的,这就搞不懂了,我的电筒不是3V的吗,我还不通过尾部那个可调电阻直接接上,发现比打到9级最大功率时要稍稍亮一点,这就搞不明白了,请高手赐教啊.</FONT><FONT size=5> </FONT></P>

<P>808就是这个样子的,我的5mW的坏了拆开了与这个一样,但估计是个小功率的,比如0.35W-0.5W。</P>
<P>100mW绿光的LD,应该是0.75W或者是1W。</P>
<P>LD工作电压的确不超2V,里面有降压、恒流电路,3V电池不直接接LD。</P>

像这样的管子

像这样的管子635   15MW左右的哪有卖多少钱?

<P>推荐1。85V</P>
<P>可以安全用在电压绝对稳定的1。89V,</P>
<P>最大超过1。91V就可能会烧了或严重折寿了。</P>
<P>如果买到好的不烧,那么晶体可能会先烧了。</P>
<P>你的3V是电路用3V,电路输出还是1。85V</P>

<FONT size=5>不是说晶体可承受几千度高温吗?</FONT>
