The invention relates to a motor vehicle headlight (1) comprising a light module having a plurality of light sources (110, 120, 130) and a plurality of primary optics (210, 220, 230), wherein the light sources (110, 120, 130) each have a light-emitting surface (111, 121, 131) and are arranged on a common circuit board (50). The circuit board (50) has a circuit board reference point and a light reference plane, wherein the light reference plane is defined by at least three light reference points, and the circuit board reference point lies in the light reference plane. The primary optics (210, 220, 230) each have a light-incoupling surface (211, 221, 231) and a light-outcoupling surface (212, 222, 232), and are held in position by a common holder (60). The holder (60) has a holder reference point and an optics reference plane, which is defined by at least three optics reference points (21, 22, 23) and in which the holder reference point also lies. At least three spacer means (41, 42) are arranged between the circuit board (50) and the holder (60) at the respective light reference points and optics reference points.

A headlight (1) includes a lamp unit (20) including: light sources (52R,52G,52B) that emit laser light; and phase modulation elements (54R,54G,54B) that diffract the laser light emitted from the light sources (52R,52G,52B) with a phase modulation pattern that is changeable, and emit light of a light distribution pattern based on the phase modulation pattern. The lamp unit (20) adjusts a total luminous flux amount of light emitted from the lamp unit (20) according to the light distribution pattern.

A vehicle headlight includes a light source and an adjustable objective. The light source is designed as a field having a plurality of microlight sources. The adjustable objective includes at least three lens groups, at least two of which are designed to be displaceable along the optical axis in order to adjust the focal length and the focal plane.

A vehicle lamp having a switching structure for low-beam and high-beam headlights is provided. The vehicle lamp includes a heat dissipating device, an LED light source, an electromagnet, a reflector, a lens unit, a light-shaping plate, a driving rod, and an adjustment rod. The LED light source and the electromagnet are disposed on the heat dissipating device, and the light-shaping plate is rotatably disposed above the electromagnet. The driving rod is disposed between the electromagnet and the light-shaping plate. The electromagnet drives the driving rod to synchronously drive the light-shaping plate to be moved to a first position or a second position. The adjustment rod is disposed on the heat dissipating device, one end of the adjustment rod abuts against the light-shaping plate, and another end of the adjustment rod is exposed from the heat dissipating device.

With a simple configuration, a clear illumination area with suppressed blurring is formed, and a form such as position, shape, and size thereof is changed. Divergent light from a point light source is shaped by a collimating optical system and emitted to a hologram element. Since the point light source is arranged at a front focal position of the collimating optical system, the light emitted from the collimating optical system is emitted to the hologram element as parallel light, and diffracted light therefrom forms an illumination area at a predetermined position on an illumination target surface. A light scanning part rotating about a predetermined rotation axis is arranged between the point light source and the collimating optical system, and light incident on the collimating optical system is scanned. By this scanning, an incident angle of the parallel light incident on the hologram element changes, and the illumination area changes.

A headlamp for a vehicle configured to generate a lighting region (3) in front of the vehicle comprises: a fixed matrix-array first light source configured to emit a high beam, a movable second light source configured to emit a low beam, a correcting mechanism configured to keep a vertical inclination of the low beam constant with respect to a reference horizontal line, when the vehicle is in motion, and a dioptric prism configured to remove at least one shadow region that may occur, in said lighting region, between the high beam and the low beam.

An illumination system for a vehicle includes a headlight configured to emit a light beam along an optical path and into an environment. The illumination system includes an optical element having a body comprising four sides. The optical element is positioned along the optical path and configured to redirect the light beam. The illumination system includes a front lens positioned along the optical path and configured to receive the light beam from the optical element and collimate the light beam as the light beam passes into the environment. The optical element is configured to move around an optical element axis to translate the light beam relative to an azimuth plane of the environment.

A lighting device configured for controlling a light radiation direction thereof, may include a housing provided with a light source; a lens unit provided in the housing, the lens unit being configured to concentrate the light generated from the light source; a length-variable unit mounted to the housing, the length-variable unit being configured so that a length thereof is changed, in a response to application of electricity thereto, in a direction in which the position of the lens unit is changed; and a controller configured to control a light radiation direction of the lens unit by setting a voltage of the electricity to be applied to the length-variable unit so that a length of the length-variable unit is changed according to a set voltage and the position of the lens unit is changed according to a change in the length of the length-variable unit.

The present invention relates to a vehicle lighting device including a lens intended to deflect the light rays emitted by a light source and including a wheel sector with a driven surface. The wheel sector is made in one piece with the lens as a whole. Also included is a driving means with a driving surface such that the driving surface is in contact with the driven surface, and movement of the driving surface drives movement of the lens.
