Illumination unit for vehicle, comprises light source and optical element, where light is emitted through optical element by light source, and light is partially focused, where optical element comprises diffractive optical structure

摘要

The illumination unit (1) comprises a light source (1.2) and an optical element (1.3). The light (L) is emitted through the optical element by the light source. The light is partially focused, where an optical element (1.4) comprises a diffractive optical structure (S) which is arranged in an emitting direction (R). The diffractive optical structure is formed, such that a three dimensional form is produced on a location inside or outside the illumination unit.
