摘要： A lighting device for vehicles, in particular a signal light, with a light source for emitting a light beam and an optical unit associated with the light source for producing a predetermined light function, the optical unit having a holographic element and a lens arranged in the main emission direction in front of the holographic element, the holographic element comprising such a diffraction structure that the light beam emitted from the light source onto the holographic element is varied according to a predetermined illumination pattern such that the holographic light beam lights an illumination surface of the lens to generate the light function.

摘要： A lighting device for vehicles having a laser light source and an optical unit which is associated with the laser light source and which generates a predetermined light distribution. A diffusion element is arranged between the laser light source and the optical unit for reducing and/or preventing a speckle pattern in the light distribution.
