摘要：

Besides their electrical properties the optical parameters of LEDs also depend on junction temperature. For this reason thermal characterization and thermal management plays important role in case of power LEDs, necessitating tools both for physical measurements and simulation. The focus of this paper is a combined electrical, thermal and optical characterization of such devices. In terms of simulation a novel approach of board-level electro-thermal simulation is presented whereas in terms of measurement, a combined thermal and radiometric characterization method is discussed.
