LED怕热，不像金卤灯，金卤灯不需要散热，正常工作，LED一热就*翘翘，LED应用要比金卤灯难的多，所以新手们一定要先把理论搞透彻，再下手，不能盲目模仿。一，散热器选择：LED必须用散热片＋风扇，散热片体积大的热阻小的最好，但是一般大体积散热片会带来很多不便，经过筛选实验，选取高级显卡散热器（3热管，4热管，5热管）5热管当然是首先了。二，LED热保护：凡事都有万一，万一LED温度超过安全值，怎么办？加热保护，温度未到提前保护！保护点自由控制，高温断开LED电源，这样LED还会热坏吗？三，风扇降噪：散热有风扇，并且夏天和冬天温度相差很大，所以LED可以采取多档调速，来降低噪音，散热片冷，风扇就低速，散热片热风扇就提速，也可以用热敏电阻，设计成更精密的，全自动温控调速，业余情况下，可以用普通温控开关来设置简单的2挡调速。

DIY投影机的制作真的很奇特,采用LED光源做投影机也只有DIY投影机发烧友们想得出来，用LED光源来做投影机光源可以5年不用换投影灯泡。想什么色温就什么色温,喜欢偏暖就偏暖,喜欢偏冷就偏冷,喜欢纯白?没问题!到处都有你想要的产品!光源是纯粹的冷光,不含紫外线,不含红外线,低压供电,什么散热风扇,什么高压电路,什么温度感应,什么过载保护,通通都去见鬼不吧!它唯一的缺陷就是强度不够,可是,强度可以用数量来弥补

diy投影仪led光源设计的技术要点：LED光源采用的是36V电源，有3路，一路依然用来提供新的屏和*版，一路用来提供水冷水泵运转，一路做了风扇的电源，原先的延迟电路也保留了。LED光源本身发光体有4*4厘米，正好完美的配合原先的聚光镜，其实面积已经等于略大于聚光镜，所以要不要聚光镜其实无所谓的了。材料是黑色文件夹的塑料封面，黑色，容易*，不变形有挺度和韧性。光路不聚焦，要检查主要是镜头，一是镜头的涵盖是否满足让屏的每个位置每个点都能在一个焦平面上成像。看买的镜头是否焦距正确、口径足够、光学素质优良。二是，屏要垂直于镜头中心线，并且光源中心，屏中心、镜头中心在一条水平线上。
