I’ll just describe my workflow, maybe it will help you (have a look here there you can see the backside of such a lamp as well). I’m not a native speaker, so if anything is unclear please ask!
Materials
- MDF for the frame
- HDF for the front and back
- frosted acrylic glass
- some aluminium foil
- some scrap wood
- an rgb strip like this one
Workflow
- cut 4 pieces for the frame and glue them together
- cut the front including the logo. The size should be fitting for covering the frame completely (if you’re looking from the front side at it)
- glue the front to the frame and sand it nicely
- paint it
- sand a gap into the bottom of the frame, so you have some space for getting the cables out of the lamp
- glue the acrylic glass to the backside of the front (carpenter tape is the easiest method in my opinion)
- cut the back in a way, that it will fit into the frame nicely without too much of a gap
- glue 4 pieces of wood into the corners of the frame; they should be large enough to drill into and fit a screw, but not too large; glue them in a way, that the distance from wood to the back of the frame is the thickness of your back HDF
- glue the aluminium foil to the inner side of your back, with the shiny side upwards; this will improve the lighting quite a bit
- glue the rgb strip into the inner sides of the frame; the more, the better
- lay the back onto the 4 wood pieces glued into the corners of the frame, drill a hole in each one and fit a screw into it
- done
