High color-saturation lighting devices with enhanced long wavelength illumination
Abstract:
A lighting device including a blue solid state emitter, at least one yellow-green or green lumiphoric material, and at least one red or red-orange solid state emitter provides high color saturation, preferably in combination with a high R9-prime (modified R9) color rendering value, with such condition(s) being obtainable with at least one of (i) a red emitter peak wavelength of at least 630 nm, (ii) a green lumiphoric material having a narrow peak wavelength, and (iii) a blue shifted green color point within a specified region of a 1931 CIE chromaticity diagram, and obtainable without requiring a notch filtering material. Aggregate emissions may have a CCT in a range of from 2000K to 5000K.
