Abstract
The invention relates to a surface light source with a lighting surface that includes at least one semiconductor body that emits electromagnetic radiation from its front side during operation. Decoupling structures are suitable for producing a local variation of the light density on the lighting surface, so that the light density is increased in at least one illumination area with respect to a background area.
