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.

Method and system for avoiding pixels errors in high-definition headlamps

A lighting apparatus for a motor vehicle includes a daytime running light device, a low-beam, high-beam, or low- and high-beam light device, and a drive device operable to drive an illumination level of the daytime running light device. With the low-beam and/or high-beam light device switched off, the drive device drives the daytime running light device so as to have a first illumination level. With the low-beam and/or high beam light device switched on, the drive device drives the daytime running light device so as to have a second illumination level. With the low-beam and/or high-beam light device switched on and with poor weather conditions, the drive device drives the daytime running light device so as to have a third illumination level. The second illumination level is less than or equal to the first illumination level. The third illumination level is less than the second illumination level.

An adjustable fixing element, particularly for headlights of motor vehicles, has a setscrew on which a first screw element and a second screw element are arranged with locating surfaces which face each other. In order to create an adjustable fixing device which can be adjusted higher from the side of the plate facing away from the object to be fixed or from another holder, it is proposed to provide a handling aid on the first screw element which projects beyond its locating surface. The second screw element exhibits a corresponding recess in its locating surface for receiving the handling aid of the first screw element.
