Hi all, I am using some small LEDs for a project, and the goal is to create a small light fixture. I am trying to find a good material to use to diffuse the light from the LEDs. I have looked at theatrical gel filters, but these are flimsy and impermanent. Is there a way to use a piece of Lexan and coat it with diffusion material? If so, what diffusion material would work best? Or is there some kind of plastic like Lexan that already has a suitable diffusion coating? Any help is greatly appreciated! Thanks!

I don't understand what's your goal, anyway I heard sometime solution base on optical-fibers. I can't help you further! Cheers

Well, it mostly depends on the design, but you could also diffuse the LED with fine sandpaper, or use plexiglass - it is available with various textures, for example as replacement panels for fluorescent fixtures, or can be easily 'frosted' with sandpaper too.

Cut off the top of the LED. See, http://www.uchobby.c...l-led-diffuser/ Baxter

+1 on sandpaper, or use a defusing material such as a paper ball (probably not suited for this application).
