Author Clemens J.M. Lasance, Guest Editor Fact: many papers discussing LED thermal management issues report values of about 100 W/cm2 and use the same arguments that are valid for ICs to demonstrate that some critical value has been reached. The question to be addressed: is this indeed a fact, or can it be shown to be a fairy tale, and hence do we need different … [Read more...]
