摘要： A light fixture, e.g., as an artificial skylight, in which light within a region defined by x, y color coordinates (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14) exits a first light engine, and light within a region defined by coordinates (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits a second light engine. Also, light fixtures in which a second light engine comprises a sidewall, and light exiting a first light engine passes through space defined by the sidewall; light fixtures in which first and second light engines are able to output light providing different CS values at a luminance; light fixtures in which light incident on a surface of the fixture and cumulative light exiting the fixture have different color points; light fixtures in which light distribution characteristics of light engines differ; and/or other features. The invention also relates to corresponding methods.

摘要： A lens for distribution of light from a light emitter having an emitter axis. The lens comprising an inner surface and an output surface with faceted and smooth outer regions. At least one of the faceted outer regions is formed by a plurality of pairs of transverse outer regions extending in direction of a plane of bilateral symmetry of the lens. The inner surface defines an inner cavity about the emitter axis and has inner-surface stepwise discontinuities formed by a plurality of pairs of transverse inner regions with intersection regions therebetween. The lens may also have at least two secondary surface portions spaced apart and extending along two sides of the inner surface, the secondary surface portions being configured for total internal reflection (TIR) of light received from the inner surface.

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 appears as a skylight and is referred to as a skylight fixture. First and second light engines of the fixture provide different color points, peak light intensity angles, far-field light distribution characteristics, and/or circadian stimulus values. A skylight fixture may include a sky-resembling assembly and a plurality of sun-resembling assemblies, with dedicated optical assemblies and/or light sources. A lighting fixture may include multiple waveguides that different extraction feature patterns and/or may be sequentially arranged.
