Abstract: An edge-fed waveguide luminaire includes a light waveguide having a planar body, a waveguide edge support structure, and an anchor opening in the planar body of the light waveguide, which is displaced from said waveguide edge support structure. A sensor is fixed in the anchor opening of said light waveguide so as to be responsive to conditions in the space below the luminaire. The sensor, which will have minimal impact on the aesthetic qualities of the luminaire, is in communication with light switching means for adjusting the light output from the luminaire in response to changes in conditions in the space below the luminaire.

Abstract: A power cord integrated hanger system for suspending a lighting fixture has a flexible load bearing inner suspension part and a flexible non-load bearing outer conductor part that acts as the “power cord” for the suspended lighting fixture. The flexible outer conductor part has an internal passageway for the inner suspension part. An outer cover of the outer conductor part holds electrical conductors in place in the outer conductor part and preferably conceals the conductors from view. The outer cover of the conductor part can be provided with different aesthetic qualities to enhance the visual appearance of the hanger system.
