How to EVENLY backlight a sign using LEDs? (similar to a lightbox)
I have a circular sign that is 24" diameter. It is 3" thick and the face has glass with a printed vinyl graphic on the inside. I need the graphics to be nice and evenly bright in the dark, similar to those movie posters, or even a lightbox. I want to use LEDs because I don't want heat and also there's going to be some devices inside so there isn't much room for flourescent or neon.
I've done research and found several flavors of led strips but not sure what will be best.
What's the best way to back light it nice and evenly? I don't want spotting to occur wherever the LEDs are. I would really appreciate as much detail as possible because I don't know anything about electronics and what components I would need.
