Abstract:
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. Also, methods.
