ABSTRACT:
This invention relates to uniform backlighting of surfaces by semiconductor light sources. Various semiconductor light sources are combined into identical illumination groups. These identical illumination groups are arranged so that uniform backlighting of a surface is made possible. For homogeneous color mixing to be achieved, especially at edges, each illumination group in the arrangement has at least one adjacent illumination group in a different orientation.
