High beam headlight
High beam headlight that can be produced with a small installation length with high efficiency and also provide effective low-cost manufacturability are described. For this purpose, a light source array having a plurality of light sources is combined with a honeycomb condenser. A collimator connected between the honeycomb condenser and the light source array illuminates the honeycomb condenser with collimated light of the plurality of light sources of the light source array. The arrangement of the components is such that the collimated light from a first light source leads to crosstalk-free irradiation of the honeycomb condenser and illumination of a first far-field segment. For each of the at least one second light source of the light source array, the collimated light of the respective second light source leads to irradiation of the honeycomb condenser with channel crosstalk and an illumination of a second far-field segment oriented obliquely with the first far-field segment.

Lighting device for a motor vehicle headlight
The invention relates to a lighting device (1) which comprises an imaging unit (2) which is configured to generate an intermediate light image in an imaging plane (ZBE, ZBE′), wherein each imaging unit (2) is composed of a light source (3) and a collimator optics (4), wherein the collimator optics (4) are designed in such a way that the light emitted by the light source (3) in the imaging plane (ZBE, ZBE′) is imaged as an intermediate light image, and wherein the lighting device (1) comprises a projection lens (5) which has a focal plane (BE), and the imaging unit (2) and the projection device (5) are arranged with respect to one another in such a way that the imaging plane (ZBE, ZBE′) lies substantially in the focal plane (BE) of the at least one projection device (5). According to the invention, the imaging unit (2) is designed as a convergence imaging unit (2) being characterized in that the body (4A) of the collimator optics (4) is designed such that the light, which is coupled into the body (4A) via the light coupling region (41A) form a collimator body light bundle (KLB, KLB′) converging into a common virtual intermediate light image plane (VBE, VBE′), wherein the virtual intermediate light image plane (VBE, VBE′) lies in front of the imaging plane (ZBE, ZBE′) of the convergence imaging unit (2) in the direction of light propagation, and wherein a light exit surface (41C) of the body (4A) is designed in such a way that when the collimator body light bundle (KLB, KLB′) exits from the body (4A), the light beams are deflected at the light exit surface (41C) and are formed into an exit light bundle (ALB, ALB′) such that the light beams of the exit light bundle (ALB, ALB′) form the intermediate light image in the imaging plane (ZBE, ZBE′), which intermediate light image lying in the imaging plane is imaged by the projection device (5) into a region in front of the lighting device (1), e.g. into a traffic area in front of the motor vehicle in the case of a lighting device installed in a motor vehicle, as a light distribution or part of a light distribution.

Optical unit
An optical unit includes a first light source, a second light source, a rotary reflector that rotates about an axis of rotation while reflecting first light emitted from the first light source, and a projection lens that projects the first light reflected by the rotary reflector into a light illuminating direction of the optical unit to form a first light distribution pattern. The second light source is disposed such that second light emitted from the second light source enters the projection lens without being reflected by the rotary reflector. The projection lens is configured to project the second light into the light illuminating direction of the optical unit to form a second light distribution pattern such that the second light distribution pattern overlaps an end portion of the first light distribution pattern in a right-left direction.

METHOD AND SYSTEM FOR AVOIDING PIXELS ERRORS IN HIGH-DEFINITION HEADLAMPS
A high-definition vehicular headlamp has a light module configured to produce a matrix of light-emitting points each of which has a coordinate pair. The headlamp generates a light image in front of the vehicle, and the light image is divided into a matrix of pixels that correspond respectively to the light-emitting points of the light module. A specified partial image content is generated in a partial region of the light image. The partial image content acts upon a set of coordinate pairs of light-emitting points, including coordinate pairs having defective light-emitting points that could cause pixel errors. A displacement vector is formed by comparing coordinate pairs of defective light-emitting points with the set of coordinate pairs of the light-emitting points on which the partial image content acts, and the partial image content is reproduced in the partial region of the light image that has been displaced by the displacement vector.
