An adjusting device for headlights, in particular for truck headlights, comprising a linear drive unit containing a threaded rod mounted for rotation, in threaded engagement with a control element, which control element can be moved in the axial direction of the threaded rod by turning the threaded rod, a pivot lever which has an articulated connection to the actuator, and an engagement element of the pivot lever which can act on the lighting unit to be adjusted, wherein the articulated connection is formed by a bearing part of the pivot lever and by a supporting part of the actuator such that the pivot lever can be turned about a horizontal pivot axis extending through the articulated connection, such that the engagement element is arranged in an upper region of the pivot lever in the vertical direction, and such that the articulated connection is arranged in a lower region of the pivot lever in the vertical direction.

To determine spatial orientation of a vehicle, a set of illuminators is mechanically coupled to the vehicle so as to emit light toward a roadway. A set of sensors is mechanically coupled to the vehicle to receive the emitted light as reflected from the roadway. A timer determines times of flight between emission of the light by the set of illuminators and reception of the reflected light by the set of sensors. A processor determines the spatial orientation of the vehicle from a difference in the times of flight.

A lighting system for a vehicle is disclosed. The lighting system comprises an imager configured to capture image data in a plurality of image frames in a rearward field of view. The system further comprises at least one headlamp configured to output an emission of light at a plurality of elevations and a controller. The controller is in communication with the imager and the headlamp. The controller is operable to process the image data to identify features in a first frame and a second frame. The controller is further operable to identify a movement of the features from the first frame to the second frame and adjust the elevation of the output emission in response to the movement.

The active lighting device of a bicycle includes a first optical system with a first light source for long-distance illumination, controlled by a control unit, and a second optical system with a second light source for short-distance illumination, controlled by the control unit. It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

The present application relates to a method for controlling a controllable headlight of a motor vehicle, in which the headlight is controlled in such a way that a predefinable light distribution is made available on a traffic route on which the motor vehicle is guided, wherein a profile of the traffic route is determined, and a light output of the headlight is set as a function of the determined profile of the traffic route in order to make available the predefinable light distribution, wherein the light distribution is made available by means of a multiplicity of pixels of a pixel headlight as a controllable headlight, for which purpose the lighting elements which form the pixels are controlled individually with respect to their light output, a region of the traffic route is determined in the direction of travel in front of the motor vehicle, which region is determined to be travelled on by the motor vehicle and is correspondingly bounded laterally, and the lighting elements are controlled in such a way that exclusively the region is illuminated with the predefinable light distribution.
