Skylight fixture

A skylight fixture comprising:

• a sky-resembling assembly comprising 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 optical assembly as skylight light;
• a plurality of sun-resembling assemblies that are arranged adjacent one another and extend downward from a periphery of the sky-resembling assembly, each of the plurality of sun-resembling assemblies comprising 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, wherein the planar interior surfaces of the sky-resembling optical assembly and the plurality of sun-resembling optical assemblies define a cavity;
• and
• at least one control module configured to, in a first mode, drive the sky-specific light source and each sun-specific light source such that the skylight fixture provides circadian stimulus greater than 0.3.
