An illumination apparatus for a motor vehicle comprises: a light source, an optical waveguide with an incident surface and a reflective region; and a hologram arranged on or in the optical waveguide. The illumination apparatus is configured such that light emitted by the light source enters the incident surface of the optical waveguide in the direction of the reflective region, is reflected by the reflective region inside the optical waveguide in the direction of the hologram and interacts with the hologram. The average distance between the light source and the incident surface is at least half as great as the average distance between the reflective region and the hologram.

Illumination apparatus for a motor vehicle

The disclosure relates to a vehicle headlight (), for example a motor vehicle headlight, wherein the vehicle headlight comprises a light source assembly () and a primary optics (A), for example a press-molded primary optics, for example a one-piece primary optics (A), wherein the primary optics (A) comprises at least one light tunnel () and a wedge-shaped light conducting part () having at least one light exit surface (A), for example optically effective light exit surface (A), wherein the light tunnel () comprises at least one light entrance surface (), for example an optically effective light entrance surface (), into which light generated by means of the light source assembly () can be irradiated, wherein the light tunnel () transitions into the light conducting part () at a bend (), and wherein the vehicle headlight comprises a secondary optics (B) with an optically effective light exit surface () for imaging a light exit surface (A) of the primary optics (A) and/or of the light conducting part () or for imaging the bend ().

Vehicle headlight

The present disclosure relates to a headlamp lens for a vehicle headlamp, wherein the headlamp lens comprises a precision-molded body made of a transparent material, wherein the body comprises at least one light tunnel and a light-conducting part with at least one optically active light exit surface. The light tunnel comprises at least one light entry surface and merges with a bend in the light-conducting part to depict the sharp bend as a light/dark boundary by means of light coupled or radiated into the light entry surface. The surface of the light tunnel is at least partially convexly curved in the region of the bend.

The lens body includes a light input portion with a light entry face, a light tunnel extending from the light entry face and defining an optical axis, and a transition face located opposite the light entry face and curved in a plane parallel to the optical axis; a light passage section with a light exit face and coupled to the transition face, such that the transition face is imaged by the light passaged section as a light/dark boundary. An upper surface of the light tunnel defines an ellipsoid with both the maior and minor semiaxes extending in a direction orthogonal to the optical axis; the maior semiaxis being at least 1.9 times the minor semiaxis. A light source might be coupled to the lens body to form a vehicle headlight.

Lightguide lens for a vehicle headlight

A headlamp lens includes a transparent body having at least one light tunnel defining at least one entry area, and a light-directing part with at least one optically active light exit area. The light entry area merging into the light-directing part at a sharp end to project a light/dark boundary by means of light coupled or radiated into the light entry area.
