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 in this article will ensure the best performance and the longest life.”

So begins a guest columnist Adrian Rawlinson, MD of Marl International, who describes techniques for the thermal design of high brightness LED packages in lighting systems. See – Good thermal design extends LED lifetimes
