Abstract:
1. 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; 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 at at least one end of the row of light-emitting semiconductor components, a transverse side face which is illuminated during operation at least by the light-emitting semiconductor component arranged at the end of the row and which is intentionally formed such that it is absorbent for a light emitted by the semiconductor component, such that it reflects 5% or less of the light which is emitted by the semiconductor components and impinges on said side face; wherein the transverse side faces, the longitudinal side faces, the diffuser, and a carrier form a luminous box with an interior space in which the light-emitting semiconductor components are arranged; wherein the diffuser is arranged on the top side of the luminous box opposite the carrier; wherein the light-emitting semiconductor components are arranged on the carrier; and wherein light is emitted from the illumination arrangement through the light coupling-out area of the diffuser.
