Enhancing light sources color homogeneity in high-power phosphor-based white LED using ZnO particles

After analyzing the scattering properties through the scattering cross-section Csca(D,X), scattering coefficient psca(J) and scattering phase function p(6,X), the which outcomes comfirm that ZnO can enhance the scattered light in the phosphor layers. [...]the findings from the study of ZnO concentration from 2% to 26% suggest that color uniformity also depends on the fluctuation of ZnO concentration, therefore, to control color uniformity the focus should be implied on both size and concentration of ZnO. [...]many changes in different parts such as the structure configuration [10], reflector [11], exterior phosphor layer [12], and packaging order [13, 14], were made to address the problems. [...]without the assist of thorough analysis and in-depth instruction on the technique, the optimal particle setting for the enhancement of CCT has yet to be decided. [...]the effects of ZnO at different sizes on lighting characteristics such as correlated color temperature and the consistency of light intensity in light-emitting devices remain undiscovered.
