LED bar wall brackets

thingiverse

A Tinkercad-made design features brackets that screw directly to walls and conceal screw holes via plugs. The brackets accommodate an aluminum extrusion housing LED strip, powered by a 12V DC supply, such as a repurposed power brick. This setup illuminates the wall, with both screw connections and electrical provisions provided on the brackets. The aluminum tube profile is PDS-O series Klus Profile Housing from SuperbrightLEDs. An example application shows two of these lights installed on either side of a bed, controlled by microswitches attached to an Arduino in a nearby enclosure. The switches turn on the side lights with one click, add the behind-the-bed light with the second click, and shut off the side lights while maintaining the other light with the third click. A fourth click turns everything off. Alternatively, a Digistump could replace the Arduino for a tidier setup. The design's CAD file can be edited online at Tinkercad via the provided link.
