Multi-function luminaire

Abstract

A recessed light fixture includes a housing, a cap affixed to an upper edge of the housing, and a cover plate having an aperture formed therein and affixed to a lower edge of the housing. A junction box and transformer having associated wiring are affixed to the cap. Mounted within the housing of the recessed light fixture is a reflector having opposing first and second reflector surfaces, a first end, a second end, and a prism having at least one diverging lens. The prism is slidingly moveable within the second end of the reflector. A bulb is electrically connected to the transformer and mounted within the housing and protruding through an opening in the first end and thereby into an upper portion of the reflector. The first and second reflector surfaces are formed having a preselected parabolic geometry so that a light beam is narrowest at a preselected limit of travel of the prism closest to the bulb, and widest at a preselected limit of travel of the prism farthest away from the bulb.
