<p>A reflector for a lamp where the light source is linear or a single point, is circular, and in cross section is stepped or corrugated. The reflecting surfaces (3) of these corrugations are ring shaped portions of a set of parabolas (6d, 6e, etc.) located at different distances from the light source (2). These portions (3) are attached to diametral strips (7) attached to the outermost ring. The gaps (8) between all air to pass through, so as to cool both the light source and the reflector itself.</p> |
