摘要
We developed a simulation method for designing the luminescence profiles of white light-emitting diodes (LEDs) with multicolor phosphor blend. By taking into account the effect of the light scattering by phosphor particles as well as the reabsorption effect by phosphor species, we found a model of white LEDs to calculate the light output as a function of various parameters such as the thickness of the resins, the concentration of phosphors, and the spatial distribution of phosphor particles. This method is widely applicable to phosphor-based white LEDs with either blue or UV excitation.
