Hi Billy
Why not have the whole front panel of the stand made from a clear or opal sheet of acrylic. For this design then flood coat the face with 100% opaque black vinyl with a cut out for the text to be illuminated, or print onto some light box back lit media or use self coloured transparent film for other coloured colours etc. Bond a cheap LED ceiling light behind the cut out – the 600mm square ones for use in suspended ceilings, then build this face into your stand structure. You could always try resin doming into the cut out in the black vinyl, or contour cut clear vinyl and resin dome this before laying it into the cut out. This slight bevel effect would add to the look and illumination effect. All cheap and readily achievable with you usual tooling, plotter and printer. You could wire the LED driver to a ‘kettle plug’ socket on the side/rear of the stand so users can plug it in – or skip the driver and install a suitable Ah capacity 12v/24v battery that the customer can remove and charge separately – don’t think it would need to be a full size car battery but something a bit more modest. You can also get 1200mm x 600mm, 300mm x 300mm, and 1200mm x 300mm LED light panels for bigger or smaller areas of illumination.
Just an idea…..
Cheers
