Abstract：The relationship between the LED radiation flux,the heating power and the junction temperature change are demonstrated by experiments.In addition,the experiment data show the relationship of the LED package tp (to) temperature and junction temperature when the driving current changes or the ambient temperature changes,so as to find out the light efficiency reduction,color drift and packaging failure caused by lighting manufacturers' improper application and installation.
