  • Patent number: 10061071
    Abstract: In various embodiments, a panel luminaire (300, 400, 500) may include a housing (302, 402) that frames a light aperture (304, 404), a linear substrate (308, 408) mounted to the housing along a first plane, at least one light source (306, 406) mounted along the linear substrate to emit light along the first plane, and a planar light guide (310, 410, 510) mounted to the housing parallel to the first plane. The planar light guide may include a light extraction feature (312) to extract light emitted by the at least one light source. In some embodiments, a portion (334) of a periphery (314) of the planar light guide may be curved to redirect light emitted by the at least one light source towards the light extraction feature. In some embodiments, the planar light guide and an aesthetic panel (418, 518) of the housing may be spaced apart to form a gap (420, 520) big enough to allow for the aesthetic panel to be three dimensional.
