When compared with two conformal phosphor and in-cup phosphor structures, the remote phosphor structure has higher luminescent performance. However, it is di cult to control the color quality of the remote phosphor structure, so it has become a research target in recent years. So far, there are two remote phosphor structures used to improve color quality including dual-layer phosphor con guration and triple-layer phosphor con guration. This study suggests using those two con gurations to make multi-chip white LEDs (WLEDs) that can achieve adequate values in color rendering index (CRI), color quality scale (CQS), luminous efcacy (LE) and color uniformity. WLEDs with color temperature of 5600 K are applied. Research results show that the triple-layer phosphor con guration is superior in CRI, CQS, LE. Besides, the color deviation decreases signi cantly, meaning that the color homogeneity increases with the triple-layer phosphor con guration. This can be demonstrated by analyzing the scattering characteristics of phosphor classes through Mie theory, thus making the research results more reliable and valuable for producing quality WLEDs.
