Claim:
1. An edge-fed waveguide luminaire for illuminating a space, said luminaire comprising a light waveguide having a substantially planar body, waveguide edges, a visible bottom surface and a top surface, and further having light extraction means for extracting light fed into the light waveguide through at least the bottom surface thereof, a waveguide edge support structure, an anchor opening in the planar body of said light waveguide displaced from said waveguide edge support structure, a sensor fixed in the anchor opening of said light waveguide, said sensor being adapted to sense conditions in the space below the luminaire and being 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.
