Abstract: Combinations of solid state light emitters, optionally arranged to stimulate one or more lumiphoric materials, are used to illuminate surfaces (e.g., upright surfaces) including printed material produced with CMY or CMYK inks. Vibrancy and/or efficacy may be enhanced by increasing the effective steepness of printed ink reflectance wavelength boundaries by illuminating printed material with solid state light emitters of multiple colors having tailored boundaries (e.g., increased separation between colors and/or increased energy in spectral areas highly reflected by CMY inks, or reducing energy of emissions at wavelengths to which the human eye is less sensitive). Lighting devices may include multiple operating modes having different gamut properties (e.g., relative gamut values). One or more subregions of an upright surface bearing printed material may be preferentially illuminated with an array of solid state light emitters including multiple emitters having different peak wavelengths.

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 can simultaneously provide high color fidelity (e.g., high CRI Ra), high color saturation (e.g., high Qg), and high efficiency (e.g., lumens per watt). A subcombination of blue and yellow-green emissions is provided within one or more specified regions of a 1931 CIE chromaticity diagram. By providing sufficient green content, increased saturation can be active with relatively a short wavelength red or red-orange source while maintaining high color fidelity and efficacy. A mixture of green and yellow lumiphoric materials may be provided.

Abstract: A lighting fixture including a light source, a housing, an image sensor, and a lens is disclosed. The housing is coupled to the light source and includes an opening through which light from the light source is emitted to fill an illumination area. The image sensor is configured to capture one or more images of the illumination area. The lens is over the image sensor, and provides the image sensor a field of view that substantially corresponds with the illumination area. By tailoring the lens such that it provides the image sensor a field of view that substantially corresponds with the illumination area, the image sensor can collect information relevant to the lighting fixture.
