| Popis: | In this paper an extension of SYSRED (SYstem function Successive network REDuction) simulation tool is presented to handle the heat generated in the phosphor layer of a phosphor converted white LED device. The heating effect of light conversion and the attenuation of light flux is taken into account through a resistance network between the source (LED chip) and the active converting nodes. With this tool, the transfer function network for the lens of a Cree XP-E LED device is created and reduced so as to connect it to a similarly reduced LED model. The results from the reduced order model show a good agreement compared to measurement data obtained for devices examined in the Delphi4LED project. |
