A lighting device for vehicles includes a light source unit containing numerous light sources, and includes a hologram unit containing numerous hologram segments for generating a predefined light distribution. The hologram segments form reflection hologram segments behind and/or next to the light source unit in the main beam direction (H) of the lighting device, such that light emitted from the light source strikes the reflection hologram segment at an acute angle φ). Holographic diffraction information is stored in the reflection hologram segments for generating a signal light distribution. The light source unit contains just one printed circuit board or one printed circuit board substrate.

Lighting device for vehicles

A headlamp for vehicles is provided with a light source unit containing numerous light sources, and with a hologram unit containing numerous hologram segments for generating a predefined light distribution. Each of the hologram segments has at least one dedicated light source. The hologram segments are reflection hologram segments behind the respective dedicated light sources in the direction light is emitted by the headlamp, which light from the light sources strikes them at an acute angle and is reflected in the light emission direction in accordance with the holographic diffraction information stored in the respective reflection hologram segments.
