摘要： A lighting fixture appears as a skylight and is referred to as a skylight fixture. The skylight fixture has a sky-resembling assembly and a plurality of sun-resembling assemblies. The sky-resembling assembly has a sky-resembling optical assembly and a sky-specific light source, wherein light from the sky-specific light source exits a planar interior surface of the sky-resembling light optical assembly as skylight light. The plurality of sun-resembling assemblies are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly. Each of the plurality of sun-resembling assemblies has a sun-resembling optical assembly and a sun-specific light source, wherein light from the sun-specific light source exits a planar interior surface of the sun-resembling optical assembly as sunlight light.

摘要： 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.

摘要： 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.

摘要： 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.
