Abstract (en)
[origin: CN107906467A] The invention relates to an auxiliary lens for a light source for producing a branched luminous surface, which auxiliary lens at least comprises a plurality of light-guide optical elements, wherein, each light-guide optical element has a light entry region, a light exit region and a lateral surface, wherein, the lateral surface connects the light entry region and the light exit region, the light exit region faces the light entry region and is associated with a light exit surface, which light exit surface is limited by a circumferential boundary line, wherein, the boundary line is adjacent to the light exit region, and the optical elements are lined up in such a way that the light exit surfaces of all optical elements are located in a common substantially planar surface, wherein each optical element has a number of nearest neighbors, wherein, its boundary line has a number of sections each associated with a portion of the boundary line of a nearest neighbor, wherein, mutually associatedsections abut one another and have corresponding curves.
