Color uniformity enhancement for white light LED lamps by quartz particles
We present a novel method to improve color uniformity for a multi-chip white light LED. By adding quartz (SiO2) particles with suitable parameters in the phosphor layer, scattering enhancement of phosphor compound can be occurred, resulting in the higher color uniformity. The scattering ability of SiO2 particle is verified based on Mie-scattering theory. The simulation results demonstrate that the deviation of correlated color temperature (CCT) increases from 3086 K to 1956 K at the mean CCT of 8500 K.
