So Luxeons are easy to heat sink... glue it on a chunk of Al/Cu. But how about heat sinking 5mm LEDs? I know leaving as much copper on the PCB as posible will help disapate some heat from the leads, but can you heat sink by direct contact with the Epoxy body of the LED? Here is what I am thinking: Machine a pice of Al flat stock with holes in it big enough to fit the LED through so that the top of the Al stock is level with the top of the reflector cup within the LED (so that about half the LED sticks out above the Al stock). I was also thinking of using a little thermal glue to make a better thermal contact between the outside of the LED and the inside of the hole. Would this provide sufficiant heat sinking for a 5mm aray, or are the leads the only place worth heat sinking?
