LED lamp, second try

January 7, 2008 – 9:08 pm

I’d been designing a circuit to drive a string of 7 of the 1 watt Luxeon leds with constant, but variable current. I was originally going to use a constant-current driver based off of the classic LM317 voltage regulator, but in the process of testing it, I made an error in which a (not yet [...]

I’ve been designing a variable current-regulated supply to drive a string of 7 Luxeon LEDs at up to 350 mA. I’m using the classic 1 watt parts, but this could be adapted for the newer parts easily enough. Since it’s line-powered and I’m designing for a specific number of LEDs (i.e. specific voltage drop), a [...]
