Abstract

The light radiator (1) has a light outlet opening in the form of a deformable circle and the reflector is formed so that the light spot formed on an irradiated surface (F) is circular when the radiator axis is perpendicular to the surface. The light outlet opening is elliptical and the light spot has essentially uniform intensity.
