ABSTRACT:
A downward illumination assembly for directing light downward from the ceiling area of a room includes a lamp housing having a closed upper end, an open lower end disposed axially opposite the closed upper end, and a housing wall extending from around a periphery of the upper end to and defining the open lower end. The lower end is positioned adjacent an opening in a ceiling panel. A lamp is supported in a lamp socket within the lamp housing in a position to radiate light through the lower end of the housing and through the opening in the ceiling panel. A module is removably supported on the housing and carries the lamp socket. The lamp socket is removable from the lamp housing with the module to allow the lamp socket and/or associated wiring to be serviced or replaced without removing the lamp housing from the ceiling panel or disconnecting and lowering the ceiling panel from its support structure.
