voronoi ceiling lamp

It was time for an upgrade for the ceiling lamp in our dressing room. I built a first version of this idea 3 1/2 years ago. This is the improved version in all aspects.

The main body consists of two 18mm solid oak pieces. The inner part is completely hollowed out to get enough distance from the leds to the diffuser. The bottom part of the wood also has cutouts in a voronoi pattern to let the light shine through.

I designed some 3D-printed wire rope clamps to make the distance to the ceiling ajustable.

assembly process

1. Let the CNC-router cut all the parts
2. Drill all the pilot holes to screw the two plates together
3. Sand all the edges and align the two sides
4. Cut all the stripes to length and glue them in place
6. Prepare the wiring
7. solder the stripes together
8. print the wire rope holders and insert the brass threads
9. glue/screw the the wire rope holders on the top piece
10. Insert the diffuser and mount the lamp to the ceiling and connect the wiring
