High-power white light-emitting diodes (LEDs) have attracted much attention due to their versatility in a variety of applications and growing demand in markets such as general lighting, automotive lamps, communications devices, and medical devices. In this paper, the effect of the red-emitting K2SiF6:Mn4+ phosphor concentration on the color properties of the 5600K conformal packaging white LEDs (CPW-LEDs) is investigated. The research results are demonstrated based on Mie Theory by Mat Lab and Light Tools software. From the research results, we can see that the concentration of the red phosphor is significantly influenced on the CCT Deviation (CCT-D), Color rendering index (CRI), Color quality scale (CQS), and lumen output (LO) of the 5600K CPW-LEDs. This research can be proposed a novel recommendation for selecting and developing the phosphor materials for LEDs manufacturing. [ABSTRACT FROM AUTHOR]
