Disclosed is a lighting fixture for projecting a beam of light useful in theater, television, and architectural lighting applications. The fixture includes cast substrate comprised of a heat-conductive material, with a concave front side that defines a reflective surface and a convex rear side that defines a plurality of cooling fins exposed to the fixtures's exterior, to provide enhanced convective cooling. This configuration enables the use of special temperature-sensitive reflective coatings that otherwise would be subject to degradation. A receptacle is defined in the cast reflector substrate, for conformably receiving the cast base of a lamp assembly, thereby enabling a precise positioning of the lamp assembly's filaments in a prescribed position relative to the reflective surface without the need for manual adjustment. <IMAGE> |
