对于LED的二次光学处理不外乎如下几种：<br /> 1、反光杯（优点：理论上出光效率高，假如反光层镀的好的话；缺点：电镀层比较容易被氧化而效率减低；光斑的控制很难，主要是反光杯对形状和焦点位置非常敏感、而且常常受到鬼像的干扰。假如你要处理成矿灯类的光斑的话，反光杯是比较好的选择） <br /> 2、透镜（优点：处理模式多样化、光斑均匀性的问题可以比较好的解决；缺点：受温度的影响很大） <br /> 3、反光杯+透镜（特殊用途可以考虑） <br /> 4、不处理（假如你的LED光通量足够大而且对芯片的眩光不在呼的话） <br /> 对于不同封装模式的LED和同一封装模式但颜色不同的LED其光学处理都是有差别的，当然其中的差别究竟有多大，我相信只要做过都会有了解的。但是要选择何种处理模式之前请三思其中的利害得失。</div> <div class="postmsg">这里有一个鬼像的分析实例！<br /> </div> <div class="postmsg">可以增大功率<br /> 采用效率相对较低的透镜法 <br /> 出射的比较完美 <img src="static/image/smiley/default/em42.gif" smilieid="71" border="0" alt="" /><br /> 不过有个好处就是LED可以很容易组合为自己想要的任意可能光源形状</div> <div class="postmsg">所以 即使效率差点，透镜还是最好的选择。值得期待的是，有的厂商已经在为用modeling glass做准备了。</div> <div class="postmsg">反光杯的反光镀層並不好做,所以透鏡還是比較好的選擇!</div> <div class="postmsg">不错，学习了，我也准备弄灯具反射器</div> <div class="postmsg">用透镜一般就不用反光杯，透镜可以将几乎所有光都折射过去到探测屏上。</div> <div class="postmsg">学习了！谢谢版主！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！</div> <div class="postmsg">wedwdwdwdwdwdwdwdwd<br /> wdwdwdwdwd</div> <div class="postmsg">lz有见地！但反光罩并非就是低端！</div> <div class="postmsg">就效率来说：<br /> 1、反光杯的电镀层是可以做到99%，但是很容易被氧化导致反射率下降，所以如果有必要的话请做真空保护。（用单纯的反光杯做光学处理的灯具的效率不是单纯的电镀层的效率）<br /> 2、透镜的效率根据不同的应用，其效率大概在70%~93%之间，要是要求不是特别精确的话，可以近似的看做灯具的效率。</div> <div class="postmsg">看看~~~~~很难做啊 ~~~~~~~~~~~~~~</div> <div class="postmsg">谢谢楼主！！！！！！！！！！！！！！</div> <div class="postmsg">浪费了偶两块大洋<br /> 顶一下赚回来</div> <div class="postmsg">kankan ,好东西呀说得好！！！！1谢谢了 了</div> <div class="postmsg">谢谢，受益非浅 <br /> ................</div> <div class="postmsg">谢谢！！！！！！！！！！！！！！</div> <div class="postmsg">透镜来说用的比较多点，支持顶下</div> <div class="postmsg">有了好的一次透镜就不需要二次透镜也可以啊</div> <div class="postmsg">thanks a lot......good files..</div> <div class="postmsg">透镜比反射杯效率高，均匀性好！</div> <div class="postmsg">所以 现在很多需要矩形配光的场所 就直接使用一次透镜配光的了</div> <div style="height200px;"></div> </div> </div> </div> </div></div>
