Abstract:

A direct troffer-style fixture for solid state light sources for use in these fixtures. Embodiments of the present invention provide a direct troffer-style fixture that is particularly well-suited for retrofit structures. The fixture comprises a retrofit troffer assembly that is removably attached within a T grid or pan structure. The retrofit fixture can be installed in two pieces: a first including a lens structure, a back reflector and 2 end reflectors; and the second component including a second portion of the back reflector. An interior space created by the lens structure houses light emitters and in some embodiments, a light engine and/or additional electronics. One or both of the end reflectors may be movable, slidable and/or rotatable, to accommodate installation. The back reflector covers most of the interior surfaces of the troffer fixture to direct more light out of the fixture.
