Abstract

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. This paper deals with the combined electrical, thermal and optical characterization and multi-domain modeling of power LEDs. The major target is to provide with a model architecture and set of model equations the parameters of which can be all measured using a combined thermal and radiometric and photometric test setup completed with a spectrometer. Current and temperature dependent modeling of the light output of white LEDs is also addressed.
