Abstract SiO2 particles and red-emitting CaMgSi2O6:Eu2+,Mn2+ phosphor have been added into a yellow phosphor compound YAG:Ce3+ to enhance the optical efficiency of white light LEDs whose average correlated color temperature (CCT) is in the range of 5600 K ÷ 8500 K. It was observed that altering CaMgSi2O6:Eu2+,Mn2+ concentration from 2 % to 30 % while maintaining 5 % of the SiO2 strongly influenced the color rendering index (CRI), color quality scale (CQS), and lumen efficiency of the compound. Besides, through the application of Monte Carlo simulation and Mie-scattering theory, it was possible to improve the optical properties by CaMgSi2O6:Eu2+,Mn2+ and SiO2 addition. The results provided a practical approach to achieve higher luminous efficiency and better color uniformity in remote-phosphor white LEDs (RP-WLEDs).

使用发红光的 CaMgSi2O6:Eu2+,Mn2+ 提高远程磷光体 LED 的颜色质量和光通量

摘要 在黄色荧光粉化合物 YAG:Ce3+ 中加入 SiO2 颗粒和发红光的 CaMgSi2O6:Eu2+,Mn2+ 荧光粉，以提高平均相关色温 (CCT) 在 5600 K ÷ 8500 范围内的白光 LED 的光效率。 K. 据观察，将 CaMgSi2O6:Eu2+,Mn2+ 浓度从 2% 更改为 30%，同时保持 5% 的 SiO2 会强烈影响化合物的显色指数 (CRI)、颜色质量等级 (CQS) 和流明效率。此外，通过应用蒙特卡罗模拟和米氏散射理论，可以通过添加 CaMgSi2O6:Eu2+、Mn2+ 和 SiO2 来改善光学性能。结果提供了一种实用的方法，可以在远程荧光粉白色 LED (RP-WLED) 中实现更高的发光效率和更好的颜色均匀性。
