    Abstract: A multi-emitter solid state lighting device includes at least one narrow spectral output solid state light emitter, such as may be in the green range, having a full width-half maximum emission value of no greater than 30 nm. First, second, and third electrically solid state emitters may include dominant wavelengths in the ranges of 485-505 nm (or 491-505 nm), 526-545 nm, and 615-625 nm. Aggregate emissions of a solid state lighting device may comprise a scotopic/photopic (S/P) ratio value that exceeds threshold values for conventional white light-emitting devices including at least one phosphor-converted LED by at least 10%, 20%, 30%, or 40%, in combination with reasonably high gamut and brightness, over a range of desired CCT values.

    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.

    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.
