The camera I added recently gained a new boom mounted partner, a Luxeon Rebel powered spot-light. Consisting of three 200+ lumen neutral-white Rebels, the spotlight puts a lot of light onto a spot on the workbench. I’m going to pick up a diffuser optic for the collimator so it’s not quite such a tight spot. I used a paint striping gun to reflow these little guys; surprisingly my solder paste from 2007 still works!
Driving the Rebels is a 1a Buck Puck from LEDdymanics. It regulates a surplus unreglated 12v wall wart down to a safe current for the LEDs. I’ve added a potentiometer to the driver’s dimming input, giving me a little control over the amount of blinding from the light. The little circuit board uses a 5 position Molex connector to provide power to the LEDs and a cooling fan. I recycled a smallish northbridge heatsink fan to keep the leds happy.
I’ve rigged up a temporary mounting solution using a T and two more elbows.
