Abstract: Lighting devices with multiple light-emitting regions may be arranged to transmit or reflect emission portions or beams having different gamut properties, such as different gamut area index or relative gamut values. Different light transmitting surfaces or areas may be arranged to transmit emission portions or light beams having different gamut properties in different directions. Different gamut properties of different beams or emission portions may be produced by different electrically activated emitters and/or light-affecting materials such as notch filters, lumiphoric materials, and/or color pigments. A retrofit element may include a light-affecting (e.g., gamut-altering) material arranged to span across a portion of a light output surface or area of a lighting device and structure arranged for removable attachment to the lighting device.

Abstract: A solid state lighting device includes multiple solid state light emitters and a control circuit configured to adjust aggregated emissions to produce a mixture of light having an adjustable color point together with high luminous efficacy, wherein at least one color point is on or near the white body line WBL (line of minimum tint). Adjustment of color point may provide substantially constant 1931 CIE x-values; substantially constant 1931 CIE y-values, or substantially constant distance relative to the blackbody locus (e.g., with variation in CCT of at least 100K for the color points). An adjustable color point may be arranged to transition between one point near the BBL and another point on or near the WBL. An adjustable color point may provide a first color point on or near the WBL and another point having different CCT and luminous flux. Emitters selected solely from discrete bins or subregions of a CIE diagram may be used in combination to yield a point on or near the WBL.

Abstract: Lighting devices include multiple emitters (e.g., LEDs, optionally in combination with one or more lumiphors) arranged to be operated in multiple operating states arranged to produce different gamut area index (GAI) or relative gamut (Qg) values, preferably in conjunction with a small or imperceptible change in luminous flux and/or color point. A first emitter or emitter group and a second emitter or emitter group may be separately arranged to produce white light with different gamut areas. Adjustment of operation of emitters may be responsive to a user input element or sensor.
