Description

ABSTRACT:
The invention includes an optics array for beam shaping, which uses a micro lens combination, whose polygonal micro lenses are arranged in a level, whereby the geometric arrangement of the individual lenses and their diameters follow a distribution pattern.It is characterized by the fact that the number of corners as well as the length of the lens rims of each of the individual lenses of the micro lens combination is defined by a point distribution (P) of Voronoi points (2), which define a Voronoi Region (VR(p)) which can be described by the following equations for a Voronoi lens (1).z⁡(r)=c·r21+1-(1+k)·c2·r2+a4·r4+a6·r6+…
