摘要：
This study presents a novel solution, application of the red Y2O3:Eu3+ dopant phosphor, for enhancing color rendering index to more 86 for multi-chip white LED lamps (MCW-LEDs) having correlated color temperature (CCT) of 7700 K. Besides, the impacts of the Y2O3:Eu3+ phosphor on the attenuation of light through phosphor layers of the various packages is also demonstrated based on the Beer-Lambert law. Simulation results provide important conclusion for selecting and developing the phosphor materials in MCW-LEDs manufacturing.
