Abstract

In this paper, a precise simulation and detailed design of angular correlated color temperature (CCT) distribution of white LEDs covering a range of CCT from 2800K to 6500K is presented. In our best knowledge, it is the first time which the kind of research is presented. Besides, for a white LED with the CCT near 6500K, an optimum design of packaging structure with a silicone lens covering a phosphor dome performed an extreme small angular CCT deviation of 105K and 182K in simulation and the corresponding experiment respectively.
