An illumination device is provided for a motor vehicle, including a light source consisting of a number of semiconductor diodes, and a scanner onto which a light beam produced by light of the light source falls and which modifies the position of the light beam during operation of the illumination device and thereby moves a light spot generated by the light beam at a distance from the illumination device. The moved light spot allows a predetermined light distribution to be generated. The illumination device is characterized in that a beam delimiting device, which allows the cross-section of the light beam to be delimited along a predetermined boundary, is provided between the light source and the scanner. The illumination device is designed in such a way that one or more light-shadow lines can be formed in the predetermined light distribution by way of at least one section of the predetermined boundary.

A lighting device for vehicles having a light source unit containing a number of light sources, having an optical unit that is arranged in front of the light source unit in the primary direction of emission for generating a predetermined light distribution, wherein the optical unit has a micro-optical array with a multiplicity of micro-optical elements arranged in a matrix, wherein a first subarray of the micro-optical array is designed without optics to form a first partial light distribution with a light/dark boundary and with a luminance maximum in a region close to the light/dark boundary, in that at least a second subarray of the micro-optical array has such micro-optical elements. A second partial light distribution is formed below the first partial light distribution in the vertical direction. The light distribution is formed by superimposing the first partial light distribution and the additional partial light distribution.

The invention relates to a motor vehicle headlamp (101) comprising a light source (105), projection optics (102, 202) and a bracket (106, 206), wherein the light source (105) is mounted on the bracket (106, 206) and is configured to project light in the direction of a projection axis (104, 204) by means of the projection optics (102, 202), wherein the projection optics (102, 202) are mounted in a frame (103, 203) which is movably arranged in the bracket (106, 206). The headlamp further comprises a lever (107, 207) which is rotatably connected, by means of axis elements that form a pivot axis running transversely or normal to the projection axis (104, 204), to the bracket (106, 206). The frame (103, 203) comprises at least one lug (110, 210) which is located between the bracket (106, 206) and the lever (107, 207), and the lever (107, 207) is configured, in the event of a rotational motion around the pivot axis, to press on the at least one lug (110, 210), and thereby to displace the frame (103, 203) in the bracket (106, 206) along the projection axis (104, 204).

A lighting tool for a vehicle includes a first condensing optical system configured to condense a first beam at a first condensing magnification, a second condensing optical system configured to condense a second beam at a second condensing magnification, and a projection optical system configured to project the first beam and the second beam forward, wherein each of a condensing point of the first beam condensed by the first condensing optical system and a condensing point of the second beam condensed by the second condensing optical system are adjusted according to a rear-side focus of the projection optical system.

A headlamp for a vehicle. The headlamp uses individual light emitting didoes or LEDs to generate individual light beams, which collectively form a composite beam. Because of manufacturing irregularities, some of the individual beams overlap neighboring beams, and form bright spots within the composite beam, which are not desirable. It is possible to de-focus the individual beams, to thereby spread out the bright spots, and reduce their intensities. However, that de-focusing would conflict with another goal. When the vehicle follows another vehicle, some individual beams which would apply glare to the other vehicle are shut off. But it is desirable that the remaining active individual beams which flank the other vehicle have sharply defined edges. De-focusing would soften the edges. Therefore, one form of the invention selectively de-focuses individual beams only when they are not adjacent individual beams which are active.

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.

The invention relates to a lighting and/or signaling system for motor vehicles, including a light source and a lens configured for receiving light rays coming directly or indirectly from the source through an input surface and for emitting a first output beam providing a first regulatory lighting and/or signaling function through an output surface. A waveguide is configured for directly or indirectly receiving light rays coming from the source through an input surface and for emitting a second output beam through an output surface, wherein a coupling zone of the waveguide is located opposite a portion of either the input surface of the lens or the output surface of the lens.
