Abstract

At application of "pillow optics" for signal automotive lights some natural contradiction can occur between official requirement for angular distribution of Intensity (the beam should have rectangular form) and real light Intensity pattern radiated, which usually has circular or oval shape. This oval area should be bigger, than needed a rectangular pattern. Significant portion of the light misses target area; and this light is lost in such cases. Some other shape of surface is proposed for pillow optics to improve light pattern.
