Abstract In this work, a scheme of combining an aspheric reflector and a primary packaging freeform lens in phosphor-converted lighting-emitting diode (pc-LED) based lighting system design was developed. In contrast to most of previous works in which

A general reflector design method for light-emitting diodes (LEDs) with non-lambertian luminous intensity distributions is developed in this study. Curve fitting method was employed to get the mathematical expressions of the luminous intensity distri
