Abstract
Various embodiments relate to a lighting device with an optoelectronic light source, an optical body downstream thereof for distributing the light, and a diffuser downstream of the latter, onto the light entry surface of which the light emitted by the optical body falls and the light exit surface of which represents a light emission surface of the lighting device. To homogenize the luminous intensity on the light exit surface, in addition to distributing the light with the optical body, the diffuser is not provided to be uniformly scattering to such an extent that light falling thereon in a central region is scattered more intensely than light falling thereon in an edge region.
