Abstract

A lighting device having an optical device which decomposes light from a light source into a multiplicity of subbeams and directs the latter onto a surface to be illuminated is specified, a plurality of subbeams being directed onto each subarea of the surface, and it being possible to perceive individual luminous areas (9, 10) at the output of the optical device (7). <??>It is the aim of such a lighting device, on the one hand, to achieve a satisfactory brightness in the surface to be illuminated. On the other hand, dazzling of a person situated at a viewing distance (a) is to be avoided. <??>It is provided for this purpose that the luminous areas (9, 10) do not exceed a maximum size which depends on the viewing distance (a), and that adjacent luminous areas (9, 10) are at a predetermined minimum distance from one another, so that they can be distinguished from one another from the viewing distance (a). <IMAGE>
