Lithophane Lamp

prusaprinters

<p>This is a Lithophane lamp I designed for a buddy's bar. He is a Renegade Pig. It takes a panel roughly 150mm x 115mm. Print the lamp and then measure the inside opening to get the exact size based on what your printer produces. The panel is supposed to be friction fit. I lined the inside of mine with aluminium foil to help reflect more light to the panel. (Not sure if it helped or not but I did it anyway.) I also color printed the picture used for the lithophane and glued it to the back of the panel.</p> <p>To get the lamp to work I used the following parts and hot glued them inside. There is a recess for the LED:</p> <p>1 Watt Cool White LED - Heatsink Mounted: <a href="https://www.adafruit.com/product/518">https://www.adafruit.com/product/518</a></p> <p>USB Micro-B Breakout Board: <a href="https://www.adafruit.com/product/1833">https://www.adafruit.com/product/1833</a></p> <p>I used a 27ohm resistor based on using the above parts from adafruit.</p> <p>Otherwise use a resistor of appropriate value (Use <a href="http://ledcalc.com">http://ledcalc.com</a> with the parameters from your sourced LED, voltage source @ 5V). Make sure your circuit doesn't go over the max allowed USB current (recommended 100 mA, absolute max 500 mA).</p> <p>Standard Micro USB cable and charger. Basically any Android phone charger.</p> <p>Printed in Tianse Cerulean Blue PLA then primed and painted black. (didn't have black PLA on hand at the time I printed it)</p> <h3>Print instructions</h3><p>I printed this opening down. Supports are only really needed in center area if done this way.</p> <p>I also have this posted on thingiverse</p>
