Patent ID: 8070315

Claim:
An illumination arrangement comprising: a plurality of light-emitting semiconductor components, arranged in a row; a diffuser which is illuminated by the light-emitting semiconductor components during operation of the illumination arrangement, scatters light emitted by the semiconductor components during operation and has a light coupling-out area remote from the semiconductor components; and two mutually opposite, reflective longitudinal side faces, between which the row of light-emitting semiconductor components is arranged, which run perpendicular or obliquely with respect to the light coupling-out area, and which reflect at least part of the light emitted by the light-emitting semiconductor components during operation in the direction toward the light coupling-out area; wherein at least one of the light-emitting semiconductor components has an optical device having a radiation exit area having a concavely curved partial region and a convexly curved partial region which at least partly surrounds the concavely curved partial region; wherein the reflectivity of at least one of the longitudinal side faces in an edge region of the illumination arrangement is lower than the reflectivity of the longitudinal side face in a central region of the illumination arrangement; in which the longitudinal side face is provided with an absorbent material or an absorbent material composition in the edge region, the absorbent material or the absorbent material composition is applied in the form of absorbent structural units, and the density of the absorbent structural units in the edge region decreases continuously or in stepped fashion in the direction toward the central region.
