Back lit acrylit panel
Posted: Thu 24 Apr, 2014 7:50 am
Customer has given me a 600mm x 600mm x 7mm acrylic panel that has been painted on the reverse. He wants the panel back lit to highlight the painting. The panel came with some cheap stand offs (chromed plastic painted grey) that go through a much small diameter hole than other stand offs I have seen (from Lion, for example). So I will have to find something to cover the holes in the panel.
We agreed a narrow, deep profile aluminium frame, hoping that this will allow a lighting system to be fitted between the acrylic and whatever backing I use.
My greatest concern is being able to provide enough light across the surface of the panel without causing any hotspots of light. Advice from an LED supplier would be to use 4 x 500mm lines of LEDs equally spaced with a diffuser over each line, cost for this was nearing 3 figures. I have also looked a the possibility of a ready made light panel (with diffuser) but not sure of their depth yet.
Has anybody done this sort of thing before and able to offer some advice?
Many thanks.
