摘要

A reflector (10) has first (14) and second (15) focal lines. A spiral-wound filament (21) for a filament lamp/bulb (20) has first (211) and second (212) spiral sections. The two focal lines lie in a common plane. The inner edge (13) of the light-exit opening is elliptical. An Independent claim is also included for a reflector lamp with a reflector and an electric lamp fitted in the reflector.
