Defining thermal resistance for LEDs is important as some LED vendors neglect the effect of radiant flux in their calculations, which results in better data than is actually achieved in the field, noted Mentor Graphics’ András Poppe, PhD, in a recent presentation at MEPTEC’s The Heat is On event. Still another example where calculations need to be carefully weighed is determining the amount of cooling needed for reliable LED operation. Poppe explains these and other important LED testing challenges in a podcast interview.
