Intensity profiles (22, 24) of light emitted by the first and second projection devices (12, 14) are matched in the lateral direction such that, in at least one lateral peripheral region of the narrow surface (20), a gradual transition to the intensity in the wide surface (18) outside the narrow surface (2) and a substantially constant intensity between the lateral peripheral regions of the narrow surface (20) within the narrow surface (20) occur. Intensity profiles (22, 24) of the projection devices (12, 14) are designed for a shorter distance than a projection distance designated for the wide surface (18) and the narrow surface (20).

Abstract: A method is provided for monitoring an image refresh frequency of HD headlights for a vehicle. The HD headlight has a control unit that causes a display with light point sources to generate light images in continued temporal succession for a predefined time duration. An image refresh frequency corresponding to the inverse of the predefined time duration is updated by a next light image. A video signal composed of image information items and signal information items is provided to the control unit by a video interface that impresses the temporally changing information item on the signal information items of the video signal. The control unit checks the signal information items of the video signal with respect to the temporally changing information item to assess correspondence with the temporal succession available to the HD headlight and a substitute reaction of the HD headlight is initiated in the event of erroneous correspondence.

Abstract: 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.
