Downward illumination assembly

A downward illumination assembly for directing light downward from the ceiling area of a room, the assembly comprising:

• 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 configured to be positioned adjacent an opening in a ceiling panel;
• a ceiling mount carried by the housing wall and configured to provide an engagement surface for mounting the lamp housing in an opening in a ceiling panel;
• a lamp 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, the lamp socket being carried by a module that is removably supported on the housing;
• a ballast electrically coupled to the socket and carried by the module and configured to regulate current flow to the fluorescent lamp through the socket;
• the ballast being removable with the module and the socket from the housing.

• and
• a trim bezel having an upper portion and a flange extending laterally outward from around a lower periphery of the upper portion, the trim bezel upper portion being supportable by friction fit in any position within a range of axial positions within the lamp housing and configured to pass through a hole in a ceiling panel that the housing is mounted to and to be positioned within the lamp housing such that the flange is supported adjacent the lower surface of such ceiling panel.

A method for servicing components of a downward illumination assembly when the assembly is carried by and opens through an opening in a ceiling panel, the method comprising the steps of:

• providing a downward illumination assembly carried by a ceiling panel, the assembly including a downwardly-opening lamp housing, a ceiling mount carried by the lamp housing and configured to support the assembly on the ceiling panel, a lamp supported in a lamp socket within the lamp housing, and a module removably supported on the housing and carrying components of the assembly;
• gaining access to the area above the ceiling panel;
• removing a module from the lamp housing;
• servicing a component carried by the module;
• and
• re-installing the module on the lamp housing.
