using a thermoelectric cooler for High powered LEDs Answered
Has anyone tried using a thermoelectric cooler, like this one http://www.allelectronics.com/cgi-bin/category.cgi?item=PJT-7
to cool down a high powered LED star. I am considering mounting one on the back of a new Luxeon Rebel
I plan on ramping the current up to max (1 amp) on the led, and run the Thermoelectric cooler (TEC) as high as possible off a lead-acid battery. Strap a giant heat sink on it (maybe a fan too) plus thermal and silicone over the whole thing. It wouldn't be pretty, but it would be a neat experiment on how many lumens you could crank out of one of these things. Any inputs, suggestions, Ideas? Feel free to make an instructale on this if you want, I can't guarantee I will do it anytime soon.
