Abstract (en)

The light beam reflector has a reflection surface of facets to give a light field. A hollow body has a lamp at one end and a light outlet opening at the other end. The reflection surface, on a plan view in the hollow body, is divided into columns extending from the outlet opening to the lamp mounting, with the facets in rows with curvature radii which vary within a row to give a circular light field contour with a lamp without rotation symmetry, according to the value of the spatial angle where the facet takes up the light. At least some facets are cylindrical and at least some are spherical.
