Diffusing LEDs to create smooth flat panel

Does anyone know how I can get instructions and materials for building LED light panels?

I’ve seen a few LED panels on the market, but I need to create my own that are a specific size and thickness, and emit light to illuminate a room. 4" wide by up to 64" (although the 64" might be split into pieces).

The panel should be smooth light where you don’t see the LED’s behind diffuser film, and as thin as possible. I understand a white backing also helps.

I’ve done some rudimentary research on the topic but I haven’t found specific instructions on building my own panels, like how much space there should be for diffusing to happen. And I’m not sure where to find the materials either. I’ve seen panels that have different textures but they didn’t seem to be for sale to normal people.

Since I’m predesigning in Autocad I’d like to know the exact thickness of the assembly and materials involved, if possible. I could also buy some materials and play around with them. The lights might be RGB or White, but probably just white for now. Thanks!

Start with some thin, white perspex/plexiglass. I think you are going to need to experiment with diffusion and transmission of such material and arrive at LED and plastic type empirically.

Thanks for the suggestion. I did not know about white plexiglass. It’s leading to promising search results. I’ll experiment with it, but if anyone also has specs for things like light types and the way they should be spaced that would also be much appreciated. Thanks again.

I’ll definitely look into them. I found a nice selection at the company that made this video http://www.youtube.com/watch?v=PX6PuUZjOLg. Not sure if I can buy in low quantity or not. Anyway I think I’ve got most of the details worked out in my mind. Now I just need to figure out the frame.
