DOOR ASSEMBLY FOR A LIGHT FIXTURE

摘要

A door assembly for a lighting fixture. Embodiments of the door assembly include a door frame defined by two frame sides and two frame ends that define a frame opening. A diffuser panel is positioned within the door frame to span the frame opening and a refractor extends along the length of the door frame. The refractor is retained on the door assembly at its ends. More specifically, in some embodiments an aperture haying the profile of the refractor is provided in the end plate on each frame end. The ends of the refractor are inserted into the apertures of the end plates to retain the refractor on the door assembly by its ends.
