A lighting device for a motor vehicle includes numerous light sources and a collimator with numerous collimator lenses. Each collimator lens has an entry surface and an exit surface through which light from the light sources passes successively. Projection optics include a first and second transparent substrates, each with an entry surface and an exit surface. At least one array of cylindrical lenses are on the entry and/or exit surface of the first and second substrates. Light exiting the collimator first passes through the at least one array of cylindrical lenses on the first substrate and then through the at least one array of cylindrical lenses on the second substrate. The projection optics include a first array of cylindrical lenses on the first substrate, the cylinder axes of which extend in a first direction, which is horizontal when the lighting device is installed in a vehicle.

Lighting device for a motor vehicle

A lighting device is provided for a motor vehicle. The lighting device contains a printed circuit board populated with light-emitting diodes and a reflector element. The reflector element is on the same side of the printed circuit board as the light-emitting diodes. The reflector element is subdivided into numerous segments. Each light-emitting diode is dedicated to a segment, such that the light from the light-emitting diodes can be reflected away from the printed circuit board by the reflector element in a beam direction (S). An optical element for the lighting device is placed downstream of the reflector element in the beam direction (S). The optical element has different optical properties above the reflective surface of the reflector element.

A lighting device for a motor vehicle, wherein the lighting device has a circuit board with a multiplicity of light-emitting diodes arranged thereon, a transparent optical layer, and a reflector element, wherein the reflector element is arranged between the circuit board and the optical layer, wherein the reflector element has multiple segments into which the reflector element is subdivided, wherein a segment is associated with each light-emitting diode so that light emitted by the light-emitting diodes can be reflected by the reflector element and can pass through the optical layer. Two light-emitting diodes are arranged in a segment. In addition, a lighting system and a motor vehicle are provided.

Communication light device for vehicles

A Lighting device for a motor vehicle is provided comprising at least one light source from which light is emitted during operation of the lighting device. An optical component into which the light emanating from the at least one light source enters is also provided, along with a light influencing means having an active surface for selectively influencing individual pixels or groups of pixels of the light. The light influencing means reflects or deflects light incident thereon in such a way that it emerges at least partially from the lighting device. Illumination optics are formed on or in the optical component. The light is reflected or deflected by the illumination optics during operation of the lighting device onto the active surface of the light influencing means. The light influencing means is arranged outside the optical component in such a way that light emanating from the illumination optics emerges from the optical component, impinges on the active surface of the light influencing means, is reflected or deflected by the latter, and then re-enters into the optical component.
