Abstract

Improvements in the construction of lighting reflectors, having a concave reflecting surface with a cutting edge defining an opening for the emission of light from said reflector, characterized in that said reflecting surface comprises a plurality of surfaces of revolution around a common guideline passing through of said opening, said surfaces of revolution intersecting at least with a plane perpendicular to said guideline to form a plurality of arcs of circumferences having different radii and having a common center at the intersection of said guideline with said plane perpendicular to it, forming said arcs together in general a non-circular configuration.
