First Claim
Patent Images
1. A general illumination system, comprising:
- at least three light-emitting diodes, each light-emitting diode providing visible light at a preselected wavelength for optimizing color rendition index for the system for general illumination applications, each preselected wavelength being defined by a predetermined chromaticity and a maximized color rendition index at the predetermined chromaticity, the predetermined chromaticity being proximate the locus of points in chromaticity space corresponding to blackbody sources.
