Lamp/reflector assembly and electric lamp for use therein
First Claim
1. In a lamp assembly comprising a reflector structure having a reflecting surface, an electric lamp extending through an opening of said reflecting surface relative to an optical axis of said reflector structure, a mounting structure for holding said reflector structure, and a first means for holding said electric lamp with respect to said mounting structure, the improvement comprising said first means including first, second and third projecting members each having a surface disposed against said mounting structure, said projecting members being disposed about at least one edge of said first means, and said projecting members extending in a direction toward said reflector structure.

Abstract
A lamp/reflector assembly has an electric lamp (10) having a base (13) presenting projections (17-19) which touch an imaginary sphere having its center of curvature coincident with the electrical element (12) of the lamp. The reflector (1) of the assembly has an opening (6) through which the lamp (10) extends, and a convex, spherically curved mounting surface (30) aligned with respect to the opening (6). The mounting surface (30) has its center of curvature substantially coincident with the optical center (4) of the reflector (1). The projections (17-19) of the base bear against the mounting surface (30) and the optical center (4) of the reflector (1) coincides with the electrical element (12), also when the lamp occupies one of a number of positions tilted with respect to the optical axis (3) of the reflector (1).
