Abstract

Methods, luminaires and systems for matching a composite light spectrum to a target light spectrum are disclosed. Method embodiments may be optimized for simultaneously maximizing luminous output with minimal chromaticity error. Method embodiments may further be optimized for simultaneously minimizing both chromaticity and spectral error. Embodiments of the present invention may be used with composite light sources having four or more distinct dominant colors within the visible spectrum.
