Paper Abstract

This paper describes electrical method for measuring junction temperature of high power LEDs. Designed and constructed system with thermal chamber and performed a number of studies in typical operating conditions luminaires with LEDs. The results allow for proper construction of a complete LED lighting system using for operation in ambient temperatures ranging from -10ºC to 100ºC, especially in terms of matching the effective supply.
