Original Abstract

Paper brings knowledge from measurement on white power LEDs for general lighting applications considering operational conditions that affect quantitative and qualitative light parameters of LEDs as well as basic electrical parameters. These data are necessary for correct design of luminaire and even for basic understanding of LED behaviour in real applications, so it can be used for creation of proper model of LED parameters degradation. Measuring of LED parameter changes is based on spectroradiometry to provide information not only about luminous flux change but also about qualitative parameters changes such as chromaticity temperature and colour rendering index.
