Illumination device e.g. interior light for vehicle has cushion optics whose lengthening and width expansion from central point is reduced or enlarged along horizontal or vertical direction in region of optic element

摘要

The device has a light source that is arranged in optic element (1) along light exit direction. The optic element is provided with refractive elements (1.1) which are arranged as cushion optics in a grating structure. The lengthening and width expansion of cushion optics from central point (Zp) is reduced or enlarged along horizontal or vertical direction in a region of optic element.
