Desk lamp

Some time ago, I wanted to make my own desk lamp. It should provide soft, bright task lighting above my desk, no sharp shadows that could cover part of my work area, but also some atmospheric lighting around the desk in my basement office. The lamp should have a natural look around it, but since I made it myself, I also didn’t mind exposing some of its internals.

I had oak floor boards that I got from a friend (thanks, Wendy!) lying around. which I used as base material for the lamp. I combined these with some RGBW led strips that I had lying around, and a wireless controller that would allow me to connect the lamp to my Philips Hue lighting system, that I use throughout the house to control the lights. I sanded the wood until it was completely smooth, and then gave it an oild finish to make it durable and give it a more pronounced texture.

The center board is covered in 0.5mm aluminium sheets to dissipate heat from the LED strips (again, making them last longer) and provide some extra diffusion of the light. This material is easy to work with, and also very suitable to stick the led strips to. For the light itself, I used SMD5050 LED strips that can produce warm and cold white light, as well as RGB colors. I put 3 rows of strips next to each other to provide enough light. The strips wrap around at the top, so light is not just shining down on my desk, but also reflecting from walls and ceiling around it. The front and back are another piece of wood to avoid looking directly into the LEDs, which would be distractive, annoying when working and also quite ugly. I attached a front and back board as well to the lamp, making it into an H shape.

The controller (a Gledopto Z-Wave controller, that is compatible with Philips Hue) is attached to the center board as well, so I just needed to run 2 12V wires to the lamp. I was being a bit creative here, and thought “why not use the power cables also to have the lamp hanging from the ceiling?”. I used coated steel wire, which I stripped here and there to have power run through steel hooks screwed into the ceiling to supply the lamp with power while also being able to adjust its height. This ended up creating a rather clean look for the whole lamp and really brought the whole thing together.
