USB Desk Lamp

thingiverse

This is another version of my lamp creations, as there are already published "box shape" lamps and "tube shape" lamps. Now this lamp is bigger (approximately 44x15x15cm) and has a disc-shaped head (140mm in diameter), with the backside featuring a switch and dimmer. With the 5V USB LEDs, I can confidently say that the dimming works very well. In my opinion, the biggest challenges in this project are cutting the tinplate base and polycarbonate glass using a fretsaw (I used saw blade no. 5 for both). Also, soldering the cut LED strips was a bit tricky. The cutting plan can be found here: USB_Lamp_Tinplate_cut.pdf. The cut polycarbonate glass needs to be pressed into the front ring from the front at a slight angle. I fixed the glass in place with some small drops of all-purpose glue applied to the outer edge. I have tried to capture some of the working steps and assembly process in photos. The assembly is similar to "Bedside Lamp (Box)" and „Bedside Lamp (Tube). A look at the photo gallery there might be helpful as well. If you have any questions, feel free to contact me. You can find suggestions for colors of your lamp here: https://youtu.be/M-ljLmSnTrw. For this project, you will need: * 1x Ø 135mm white polycarbonate glass, 3mm thick, 70% translucent * 1x 180x120mm tinplate * 1x Ø M4x45mm from a threaded rod * 1x Ø M4x65mm from a threaded rod * 1x Ø M4x80mm from a threaded rod * 2x Ø M3x16mm + plus 2 matching washers (to connect head, neck, and light base) * 6x wing nuts Ø 4mm * 18x washers Ø 15x4.5mm * 6x self-tapping screws Ø 2.2x 2.9mm *(4x self-adhesive rubber pads Ø 8x1.6mm)* You will also need: * 2 Position Mini Toggle Switch * LED lighting strip (2m). I advise against installing another or higher wattage light source, as it may lead to excessive heat development! * Light: LED Beleuchtungsstreifen, USB TV Hintergrundbeleuchtung 6.56Ft/2m LED Band, Nicht Wasserdicht SMD 3528 5V warmweiß Bias Lighting, USB Bias Lighting für Heimkinos von Hapop Smart Life Store (available on Amazon) * Dimmer: ANGEEK PWM Motor Drehzahlsteller Modul Niederspannung DC 1.8V - 12V 2A * USB charging adapter: AmazonBasics - USB-Ladeadapter mit 1 Anschluss (2,4 Ampere) - Weiß; 2 Stück von Amazon.de The files must be printed in the following number of copies: * 1x USB_Lamp_front.stl * 1x USB_Lamp_neck.stl * 1x USB_Lamp_dimmerknob.stl * 1x USB_Lamp_back.stl * 2x USB_Lamp_foot.stl * 4x USB_Lamp_leg.stl * 4x USB_Lamp_spacerwasher.stl After completing the assembly, I recommend attaching small self-adhesive rubber pads to the bottom of the lamp feet (4x rubber pads Ø 8x1.6mm) to improve slip resistance.
