Abstract:
1. An illumination device having a luminous area and a plurality of optoelectronic components, each optoelectronic component having an optically active region, wherein the optically active region in each case comprises at least one semiconductor chip operable to generate electromagnetic radiation, the optically active region in each case comprises a beam-forming element through which at least a portion of the electromagnetic radiation which is emitted from the semiconductor chip in operation passes and which has an optical axis, the optically active region in each case has quadrant symmetry with respect to a coordinate system which is perpendicular to the optical axis, the optical axes are parallel to one another, the luminous area is arranged downstream of the optoelectronic components in the direction of the optical axes, regions on the luminous area which are illuminated by neighboring optoelectronic components overlap at least in places, and the optoelectronic components have essentially the same emission characteristics and are arranged at equal distances so that illumination intensities of the individual optoelectronic components on the luminous area overlap to produce a illumination intensity which is constant in all directions on the luminous area.
