LED Characterization Within the Delphi4LED Project

The European Delphi4LED consortium intensively works on measurement, modeling and simulation techniques to cope with the lack of standardized methodologies to describe the strongly temperature and current dependent characteristics of LEDs. The paper presents some of the efforts and results in making the lighting design of luminaires an automated, model based process; similarly to the design practice in electronics. To achieve this target, validated and standardized multiphysics LED models are needed. In this paper results in comparing standard LED measurement methods and the realized upgraded testing and modeling procedures are shown, as the authors see it after one and half year of intensive collaboration in the subject.
