A vehicle lighting device includes at least one headlight, a position and/or acceleration sensor, and a control unit for adjusting a light/dark boundary of the headlight. Pitch movements of the vehicle can be detected by the position and/or acceleration sensor, and a change in the light/dark boundary due to the respective pitch movement can be compensated for by the control unit. The position and/or acceleration sensor and the control unit are arranged in the headlight or directly on the headlight.

A method and a device for adjusting a light distribution of a vehicle headlight having a control unit for adjusting the light distribution. The headlight includes a number of light sources. The control unit includes an interface configured for receiving user-specified parameters for adjusting and/or modifying an illuminance distribution within the light distribution.

Method for determining control parameters for light sources of a vehicle headlamp

A control device for a headlight for emitting light according to a headlight signal corresponding to an adjustable light distribution. The control device outputs the headlight signal, corresponding to the adjustable light distribution, to the headlight. The control device has an evaluation unit that determines object position data of the object when particles are detected using a detection unit and a self-illuminating object is detected, and to determine, as a function of the object position data, a region in which the object is located. The evaluation unit also generates data for the light distribution as a function of the region in such a way that a light intensity in the region is reduced or increased with respect to a light intensity outside this region, and correspondingly to determine and output the headlight signal from the data for the light distribution.

A device and a method for controlling at least one headlight for a motor vehicle involve a control apparatus, at least one sensor configured to detect information about objects in a surrounding area of the motor vehicle and to supply the detected information to the control apparatus. The headlight can be adjusted by the control apparatus depending on at least one detected object. A range between at least one light source and at least one lens of the headlight can be adjusted by the control apparatus in order to adapt a projection of the light source to the at least one detected object.

Device and method for controlling a headlight

A method for the operation of a vehicle light unit is provided. The light unit includes at least one light source module having several light sources and a control unit coupled to the light source module. The light sources each include a predetermined number of brightness levels. A predetermined number of light sources are combined by the control unit to form at least one controllable light source unit. In order to set a light distribution, the light sources that form the at least one light source unit are activated together and a brightness level of each light source of the at least one activated light source unit is set individually.

A device for controlling a driving light of a vehicle includes a headlight with a light source, a device for pivoting a produced light distribution and an optical element that provides adjustable light distribution. The optical element includes a light passage opening pivotable into an optical axis of the light source. A beam of the light distribution is limited or deflected such that a limited light field is produced in a pre-settable region in front of the vehicle, which light field has an external form of the light passage opening. Further light passage structures provide a 'high beam' or 'partial high beam' light pattern and thereafter the &#x201c;high beam&#x201d; light pattern by turning, pivoting and/or displacing the optical element in one direction, and another further light passage structure provides a &#x201c;motorway&#x201d; and thereafter a &#x201c;country road&#x201d; light pattern by turning, pivoting and/or displacing the optical element in an opposite direction.

LED headlight for a motor vehicle

The invention relates to a headlightin particular based on the projection principle. The headlight has a semiconductor light sourcewhich is arranged at the focal point of the reflectorand is connected to a cooling elementThis cooling elementextends from the semiconductor light sourceto the transparent lensthrough which the light that is reflected by the reflectoris emitted, passes through the transparent lensand projects beyond it. This arrangement of a semiconductor light sourcea cooling elementand a transparent lensensures that the light sourceis cooled effectively. In addition, the arrangement and the form of the cooling elementensure that the cooling elementdoes not shadow, or only slightly shadows, the reflected light. This leads to a high light yield from the headlightaccording to the invention, and to a long life.

A conclusion may be drawn regarding the form of the blockage of the light signals by the passenger based on the light signals received, which in turn makes it possible to draw a conclusion regarding the posture, in particular the head position or the body inclination. The positions of the light transmitters and light receivers may be exchanged in an analogous manner.

In accordance with the invention the housing of the vehicle headlight () is designed to be pressure-tight and the headlight () is associated with a controller (), which controls the headlight () depending upon the pressure within the housing. The controller () brings about that the headlight, depending upon the pressure within the housing, is switched off, is adapted in its light intensity and/or is changed in its emission characteristic. Thereby a headlight is produced characterized by being safe for the eyes.
