摘要

本研究介绍了一种创新的多芯片白光LED (mcw -LED)，该LED利用了一种新合成的化合物，将红色Y2O3:Eu3+与杯内荧光粉封装结合在一起。该方案的主要优点是将相关色温为8500 K的mcw - led的显色指数(CRI)提高到大于84。此外，还利用Beer-Lambert定律证明了这种加红方式对硅酮透镜光衰减的影响。

Effect of Y2O3:Eu3+ phosphor powder size on the performance of white LED lamp

This study introduces an innovative multi-chip white LED (MCW-LEDs) that exploits a newly synthesized compound combining red Y2O3:Eu3+ with the in-cup phosphor package. The principal advantages of this solution is to enhance the color rendering index (CRI) of MCW-LEDs that have the correlated color temperature of 8500 K to a greater value than 84. In addition, impact of this red-color-adding approach on the light attenuation through silicone lens is also demonstrated using Beer-Lambert law.
