摘要：

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%.
