A light spreading lens, an automotive lighting system, and method of manufacturing a light spreading lens are described. The light spreading lens includes an outer surface. The outer surface is defined by a Boolean intersection of a first cylindrical lens overlaid with a second cylindrical lens. The first cylindrical lens is configured to distribute light along a first axis. The second cylindrical lens is configured to distribute light along a second axis.

Lighting device for vehicles

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 ). 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.
