Abstract
According to one aspect, a luminaire comprises a waveguide body including a central section and first and second separate side sections extending away from the central section along first and second opposed directions, respectively. The central section includes a coupling portion and the waveguide body has a length and includes a plurality of light extraction features that extract light out of the side sections. At least one LED is disposed adjacent the coupling portion and is operated by a power circuit to produce light that is directed into the waveguide body by the coupling portion. At least one structural member extends along the length of the waveguide body for supporting the waveguide body and encloses at least one of the power circuit and the at least one LED.
