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.
