In-situ measurements of material thermal parameters for accurate LED lamp thermal modelling (original) (raw)

19th International Workshop on Thermal Investigations of ICs and Systems (THERMINIC), 2013

Abstract

This work deals with the extraction of key thermal parameters for accurate thermal modelling of LED lamps: air exchange coefficient around the lamp, emissivity and thermal conductivity of all lamp parts. As a case study, an 8W retrofit lamp is presented. To assess simulation results, temperature is monitored on the lamp by infrared thermography and by monitoring specific locations with thermocouples. As a result, experimental and simulation results show differences below 15%.
