    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.

    Abstract: Retrofit systems and methods are disclosed for lighting installations, and in particular, to retrofit systems and methods used to retrofit troffer-style lighting installations with LED light sources. Retrofit systems can be used with different light fixtures, but those described are particularly adapted for use with troffer-style fixtures. These retrofit systems can provide the same amount of light as traditional light fixtures already do, for example 1600-4000 lumens or more. The retrofit systems can be used with many different light sources but are particularly well-suited for use with solid state light sources or light engines, such as those utilizing LEDs. Some embodiments of the present invention comprise a mechanical mounting system for installing an LED light engine within an existing lighting system housing or pan, such as a troffer pan, without penetrating the ceiling plenum.
