New Dynamic Photo-Electro-Thermal Modeling of Light-Emitting Diodes With Phosphor Coating as Light Converter Part I: Theory, Analysis, and Modeling

Phosphor-coated light-emitting diode (PC-LED) is the dominant LED technology for public lighting. This paper presents a comprehensive theory for analyzing and modeling phosphor coating (PC) in white LEDs as a dynamic light converter. The new PC-LED model not only obeys the traditional diode equation but also includes the energy storage and transient effects of the PC. Major control variables include energy storage in and the luminous flux from...
