I am looking for a cheap source of RGB led's in smt. I have a few
that I've been playing around with but some problems are:
The colors do not mix well. The purpose for using RGB was that I wanted to get many possible colors out. When I run 2 or 3 of the led's in the package I don't end up with a strong mixed color.
I also need some sort of "light pipe" that I can cut to length but diffuses the colors well enough so that the viewing angle is somewhat large and the colors are mixed well(I guess something somewhat opaque will do?).
What I'd actually like to have is a sort of "cap" or "button" that I could fit over the whole in the wood that I'll be mounting the led's in that is scratch resistant. This will cover the led and should mix the colors along with increase the viewing angle.
When the led is "lifted" to the surface(hopefully a few have been following along with my objective), which is around 4-8 mm it shines much better but is much harder to use. If I don't lift the led, such as if I put it on a pcb, it is much easier to use but then I somehow need to "lift" the light to the surface. I've seen LED pipes that do this sort of thing and I need something with the same effect but for the led's I'll be useing and also which I can cut to length. (since the length varies)
I've not seen any very thin led pipes though and I'm not sure how well they capture the led light. "Lifting" the led will give better results but harder to implement. In either case I still have to "mix" the individual colors and worry about the viewing angle(it's not a problem if the led is at the surface but is if it's below).
Any help would be appreciated, Jon
