Water-Cooled LED Light

[Matt] wanted to drive a Yuji LED array. The LED requires 30 V and at 100 watts, it generates a lot of heat. He used a Corsair water cooling system made for a CPU cooler to carry away the heat. The parts list includes a microphone gooseneck, a boost converter, a buck converter (for the water cooler) and custom-made brackets (made from MDF). There’s also a lens and reflector that is made to go with the LED array.

This single LED probably doesn’t require water cooling. On the other hand, adding a fan would increase the bulk of the lighted part and the gooseneck along with the water cooling tubes looks pretty cool. This project is a good reminder that if you need to carry heat away from something with no fans, self-contained water cooling systems are fairly inexpensive now, thanks to the PC market.
