Ryobi compatible 1200lm work lamp

prusaprinters

<p>This is a custom-made work lamp for Ryobi 18V batteries. It consists of four Nichia LEDs (5000K, CRI80, ~300lm per LED) which are dimmable in two groups with different beam angle lenses. The PCB has a buck led driver for each group. A potentiometer adjusts the current for flicker-free brightness control.</p> <p>The head of the lamp is connected to the body with a gooseneck for flexible orientation adjustment.</p> <h3>Print instructions</h3><h3>Printing</h3> <p>The lamp uses three different materials and thus needs at least three prints:</p> <ul> <li>Body: Prusament PETG Prusa Galaxy Black</li> <li>Head: Prusament PC Blend Jet Black</li> <li>Pushbutton: Flex Filament</li> </ul> <p>I used PC for the head as the heatsinks, which are in contact with the print, reach up to 90°C (at 20°C ambient temperature). This is above the heat deflection temperature for PETG.</p> <p>The pushbutton can be printed with two colors if the filament is changed after the first part is printed.</p> <h3>BOM</h3> <ul> <li>Printed parts</li> <li>4x LED Nichia NVSW219CT on 10x10mm metal core PCB</li> <li>2x Lens Carclo 10414</li> <li>2x Lens Carclo 10412</li> <li>2x Heatsink Fischer ICK PGA 11 X 11 </li> <li>2x Thermally Conductive Foil Fischer WLFT 404 24.5 X 27.7</li> <li>Gooseneck 150mm 2x M10x1 outer thread</li> <li>Nut M10x1</li> <li>10x Ruthex M3 threaded inserts</li> <li>Acrylic glass 36x57mm thickness 2mm</li> <li>Screws<ul> <li>6x M3x20 ISO 7380-2</li> <li>2x M3x20 ISO 14580</li> <li>8x M3x16 ISO 14580</li> <li>6x M3x6 ISO 14580</li> <li>1x M3x6 DIN 966 (pushbutton actuator)</li> </ul> </li> </ul>
