LED Backlit Shelves
The goal of this project was to set up an LED backlit shelving unit in an existing recess in a bedroom. This would make the space more useable for storage. Existing power had to be located and utilized. Additionally, the lights would need to have a controller switch.
Wiring schematic for shelving unit
With the new outlet, a standard LED controller could be connected to the power supply. From there, each LED strip would need to be connected via thermostat wire fishtaped and hidden behind the walls. These RGB LEDs would require (4) contacts to be made:
12V
Blue
Red
Green
To ensure compliance, I utilized riser rated 4 conductor copper 18 AWG wire. This wire is typically used for low voltage applications such as thermostats where voltage is less than 50V. Additionally, I sourced riser rated product because this would only be needed in vertical runs as opposed to lateral or plenums. All connections would be made using solder-less crimps which were a cheap and effective way to install thinner gauge wire.
2” clear oak
I bought a stick of 17” wide clear oak at 2” thickness from a local lumber supplier. I cut roughly 3’ sections that would be a snug fit in the recess.
After treating the wood with mineral spirits and polyurethane, I assembled a backstop so that items would not fall through. Additionally, the backstop would serve as a surface to attach the LEDs onto.
I installed brackets and ensured that they were positioned correctly with a torpedo level and yard stick and tape measure. I wanted to ensure that the shelves were equidistant to maximize the space. I balanced each shelf and pre-drilled each hole before setting each one. I had to carefully install solder-less crimps and terminate the connections outside the wall. Each LED strip would be taped to the back of each shelf to remain clean and hidden. This would also direct the light at the wall providing a nice visual projection.
