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).
