ABSTRACT:
A combination orientable light and ventilating fixture includes a support and a ball housing adjustably mounted therein, the ball housing including front and rear openings and an inner chamber. A socket assembly for an electric lamp is mounted on the housing behind the rear opening and held in spaced relationship from the housing. A bezel element is removably secured to the ball housing at the front opening. A plenum or equivalent arrangement may be mounted on the rear of the support to cover the socket assembly and the rear opening of the ball housing, so that air may pass through the plenum and ball housing. A reflector for the electric lamp is securable to the removable bezel element at any of a plurality of locations axially within the chamber of the ball housing, so that its position relative to the electric lamp may be selected to vary the divergence of light emanating from the fixture. The bezel element may include an inner shield integral therewith and adapted to intercept a portion of light produced by the lamp, to eliminate glare. Various further structural arrangements are provided to permit increased angular movement of the housing relative to the opening axis, to provide a limit to such angular movement, and to facilitate removal and easy insertion of the bezel, shield and reflector arrangement.
