Modern Desk Lamp 5v USB

thingiverse

I loved the sleek design of a 4020 LED desk lamp, so I decided to reverse-engineer it using a $1.90 USB led module I had on hand. All the parts were designed independently in Fusion 360 from scratch. The lamp shade features a platform for this led module or a small strip. This LED module is perfect because it comes with an aluminum channel to dissipate heat efficiently. Of course, I didn't have any 4020 aluminum extrusion available, so I printed up an approximation of it (19.9 x 39.8mm x 300mm). I added optional neck pieces in case your printer cannot accommodate a 300mm part. One of the toughest pieces to tweak was the elbow. I printed the elbow with a smooth interior and access holes so support could be pulled out as easily as possible. The elbow friction fits (tightly) to connect the shade and the neck of the lamp. Since I'm not using metal, the lamp is extremely light in weight. To overcome this problem, I created cavities for pennies in the endcap of the lamp. Pennies friction fit into the endcap. The base is adjustable with a 3mm set screw (I envision that the base will be glued in place, with weights added as needed). To print this lamp, you'll need five parts: 1) Base 2) Neck 3) Joint 4) Shade 5) Endcap Enclosed find two optional neck sizes and an optional neck joint. If you notice, I soldered black and red wires directly onto the LED strip pad and then spliced a USB male cable into the mix. I wanted to run thin solid core bell wire in the middle of the lamp rather than thick USB cable. It would be impossible to get a USB cable around the bend of the neck. For power via USB, you need red (+) and black (ground) for the lamp, and you don't need green or white. I also plan to use a USB male to female switch. http://www.ebay.com/itm/172294948377?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
