USB Desk Lamp - Dimmable - 3D Printed
Introduction: USB Desk Lamp - Dimmable - 3D Printed
Lamps for buy there are like sand by the sea. But a DIY lamp, with individual coloring, is always something special. I will not hide it, building this 3D printed lamp requires a bit of craftsmanship, especially soldering. You should also be able to handle a fretsaw (or electrical jigsaw), not to saw wood but sheet metal and polycarbonate "glass" ... I did both with a fretsaw.
In my opinion, the biggest difficulty in this project is definitely the soldering of the cut LED strips.
This lamp is very variable in its appearance due to the articulated design of the stand. In addition, light can also be adjusted individually. On the back is in addition to an On/Off switch a dimmer. With the 62 5V USB LEDs - I can say that the dimming works quite good. In order to generate sufficient brightness, a relatively large number of LEDs had to be accommodated, resulting in a rather large head (Ø 140mm).
Dimensions of the lamp: approx. H44 x L15 x W15cm
For this project you will need:
* 1x … Ø 135mm white polycarbonate glass, 3mm thick, 70% translucency (I chose this "glass" so that the light area is uniform and you can not see the LEDs. 492
Who does not attach importance to it can instead take 100% translucent material, which of course also increases the light output).
* 1x … 180 x 120 x 0,5mm tinplate
* 1 x 2 Position Mini Toggle Switch
* 1 x LED lighting strip (2m)
* 1x … Ø M4 x 45mm from a threaded rod
* 1x … Ø M4 x 65mm from a threaded rod
* 1x … Ø M4 x 80mm from a threaded rod
* 2x … Ø M3 x 16mm + 2 matching nuts (to connect head, neck and light panel)
* 6x … wing nuts Ø 4mm18x
* 14 ... washers Ø 15 x Ø 4,5mm
* 6x … self-tapping screws Ø 2,2 x 9,5mm
* 4x … self-adhesive rubber pads Ø 8x1,6mm
* ... thin copper wire (for soldering)
* ... thin 2-wire cable (for the USB power connector)
* ... USB Type A plug with cable
* ... soldering iron
* ... solder
* … fret saw (jigsaw)
* ... textile tape
* ... glue
* ... screwdriver
