Sound thermal design principles to extend LED lifetimes

“LEDs with a power dissipation of 35W or more are now available. Such lights are so bright that they are uncomfortable, if not dangerous, to look into directly, but with increasing power, there is increased thermal load and more heat to dissipate. Adherence  to the sound thermal design principles described…
