12/24 Volt Mini LED Lamp

thingiverse

I carefully crafted this lamp to operate seamlessly off my 3D printer's power supply. It boasts impressive adjustability, featuring pan, tilt, and height adjustments that make it easy to position just right. The lamp utilizes a reliable 12-volt power source or can be easily converted to 24 volts with some simple part swaps. With a nominal power consumption of only 3.6 watts, this lamp is an energy-efficient choice. By simply swapping out a different resistor, the power output can be adjusted, but be cautious not to overheat the system. Assembling this lamp requires some basic soldering skills, so make sure you're comfortable with that before getting started. One important thing to note is that the LED does get quite hot, so it's essential to use a high-temperature filament when printing the lamp casing to prevent any damage. The diffuser should also be printed using transparent filament for optimal light distribution. The various components of this lamp snap or screw together with ease, but the pegs on the side do require some additional glue to secure them in place. This ensures a solid and stable build that can withstand regular use. **Bill of Materials** * [Cree CXA1304 series LED, 9 volt](https://www.digikey.com/products/en?FV=ffec9ab8): Choose an LED with your preferred color temperature for the perfect ambiance. For 24 volts, select an 18-volt LED instead. * [10 Ohm 2 Watt Resistor](https://www.digikey.com/product-detail/en/yageo/FMP200JR-52-10R/10ZCT-ND/2058964): When using a 24-volt setup, switch to a 39 ohm resistor for optimal performance. Once assembled, this resistor will be housed safely inside the tube. * [Aavid Thermalloy Heat Sink 507002B00000G](https://www.digikey.com/product-detail/en/aavid-thermalloy/507002B00000G/HS112-ND/5846) * [Thermal Grease](https://www.digikey.com/product-detail/en/wakefield-vette/120-2/345-1007-ND/340305): Any suitable thermal grease will work just fine in this application. * [Power Switch](https://www.digikey.com/product-detail/en/e-switch/RD1113112R/RD1113112R-ND/3778106): Use any reliable power switch you prefer, and don't forget to include a printable case for the linked switch. * [Wires](https://www.digikey.com/product-detail/en/adafruit-industries-llc/2976/1528-1753-ND/6226990): Choose any wires of similar size to complete your lamp's wiring. * Power Connectors: I used [these barrel jacks](https://www.digikey.com/product-detail/en/cui-inc/PJ-038A/CP-038A-ND/1644549) and [this barrel plug](https://www.digikey.com/product-detail/en/mpd-memory-protection-devices/EP501A/EP501A-ND/2439550) to connect the lamp seamlessly to my printer. I've included a housing that securely holds two of the linked jacks, with the lid designed to be welded on using a 3D pen or glued in place for added stability.
