Abstract: A line of recessed low-glare lighting fixtures, known as HITC (hole-in-the-ceiling), provide an authentic architectural built-in appearance. A mounting unit is cast in plaster material with a vertical duct extending upwardly from a light-exit opening in a horizontal face flange that becomes plastered in place in the ceiling. The duct supports a light source and associated components above, producing a light beam of designated beam width, typically +/?45 degrees. From any room viewpoint outside the light beam, the only component of the fixture that is visible is the mounting unit, of which all visible regions, both internal and external, are made to have finish, appearance and texture that match and blend in harmoniously with the surface of the surrounding ceiling.

Abstract: A line of recessed low-glare lighting fixtures provides a totally built-in architectural recessed appearance: a special cast mounting unit has a recessed duct portion formed integrally with a flat face flange portion defining a light-exit opening. The face flange portion becomes plastered in place in a wall or ceiling with the duct portion supporting the light source and associated components. In a main embodiment for ceiling deployment, the face flange portion is made square, the light-exit opening and the duct portion can be made circular or rectangular, typically square, In an offset hidden source embodiment, usually wall-mounted with a rectangular light-exit opening to “wash” either a ceiling or a floor region, the recessed duct portion is curved and shaped to serve as a reflector surface for desired illumination distribution. The light source can be incandescent, fluorescent or metal halide, in a selection of wattage ratings. The mounting unit can be cast in different sizes according to wattage ratings.
