In this paper, by mixing the αSrO·3B2O3:Sm2+ conversion phosphor into the phosphor layer, an innovative recommendation for increasing optical performance of the white LEDs (WLEDs) with remote-packaging, which has an average correlated color temperature (CCT) of 7000K and 8500K, is proposed and demonstrated. | Increasing optical performance of 8500 K, 7000 K remote packaging WLEDs by α SrO3B2O3:Sm2+ conversion phosphor
