LED透镜设计
I have not successful experimence, but some failful lesson.
1) never consider it as a single point source unless the focusing length of lens is greater than 10mm or even more.
2) study the shape or function of its mounting cup carefully, it always behaves as a retro-reflector.
3) so far only one successful product available in the market I have seen is one LED manufacturer design for their powerful LED specially, you can find it by
www.lumileds.com/.
I am very interested in this topic, please let me know if you make any progress.
thanks in advance. |
