A holding device of a lighting module of a lighting unit of a vehicle, comprising a securing section for securing the holding device to the rest of the lighting module and a bearing section for supporting the holding device on a bearing pin of the lighting unit, wherein the bearing section has at least one lock which forms a locking connection together with the bearing pin when the holding device is assembled, and wherein the lock is designed such that the locking connection simultaneously forms a joint which enables the lighting module to rotate about a longitudinal axis of the bearing pin. A lighting module and a lighting unit of a vehicle are also provided.

An adjuster gear screw is provided that includes an adjuster shaft having a threaded portion and a shaft end, a gear head having a plurality of radial protrusions spaced by a plurality of radial indents, and a flange having a flange front surface, an elongated neck interconnecting the adjuster shaft and the gear head, and a gear having a gear rear surface, a plurality of teeth, and a plurality of fingers and notches extending along an inner circumference, wherein the gear is axially secured to the gear head in a first longitudinal direction via abutment of the gear rear surface with the flange front surface, and in a second longitudinal direction via engagement of the plurality of fingers with the plurality of indents, and wherein the gear is rotationally secured to the gear head via abutment of the plurality of radial protrusions with the plurality of notches.

A light-regulating mechanism comprising a first ball head connector, a second ball head connector, a third ball head connector and a sliding connector. One end of the first ball head connector and one end of the second ball head connector are connected to an illumination unit. The other ends thereof are connected to a supporting frame or a light body. The illumination unit is provided with a sliding support. The sliding connector can slide on the sliding support. One end of the third ball head connector is connected to the sliding connector in a sliding manner, and the other end thereof can move on the supporting frame or the light body to drive the sliding connector to slide on the sliding support, so that light regulation in a first direction is realized. Further disclosed are a vehicle light module comprising the light-regulating mechanism, a vehicle light and a vehicle.

A light-emitting assembly, a method for adjusting the light-emitting assembly, and a vehicle. The light-emitting assembly is used for a vehicle and includes a seat and a support, a light-emitting module being held on the support. A first adjustment mechanism is provided for performing a first adjustment on the light-emitting module, and a second adjustment mechanism is provided for performing a second adjustment on the light-emitting module. The support and the seat are pivotally connected together, so that the support can pivot around a horizontal axis under the action of the first adjustment mechanism.

A vehicle headlamp device to be applied to a vehicle includes a light source, a lens, and a controller. The light source is configured to emit light. Light emitted from the light source is to pass through the lens. The controller is configured to control light distribution patterns for the light. The light distribution patterns include at least a first light distribution pattern and a second light distribution pattern. The first light distribution pattern illuminates an area ahead of the vehicle during running of the vehicle. The second light distribution pattern is projected as a marking at an optical axis adjustment that is performed during manufacturing of the vehicle. The controller causes a part of the light source to emit light so that the second light distribution pattern is formed.

A fine pitch adjuster that includes a housing, a wheel gear positioned within the housing and coupled to a ball stud, wherein rotation of the wheel gear provides inward and outward longitudinal translation of the ball stud relative to the housing, and a clutching worm input drive including, an inner drive sleeve having a shaft portion and a head portion, the shaft portion including a plurality of sleeve slots formed therein and a plurality of engagement ribs, and an outer worm gear sleeve having worm gear threads, the worm gear threads coupled at least indirectly to the wheel gear, and an inner chamber, the outer worm gear sleeve including a plurality of grooves extending longitudinally along the inner chamber for mating engagement with the plurality of engagement ribs, wherein rotation of the inner drive sleeve provides clutchable engagement with the outer worm gear sleeve to rotate the wheel gear.

A light system of a vehicle comprising: (a) a connector housing; (b) a reflector housing connected to the connector housing and being movable relative to the connector housing; (c) one or more adjustment assemblies comprising: (i) a socket in the connector housing; and (ii) a rod in the reflector housing that extends into the socket and is rotatable relative to the socket so that the reflector housing is adjustable relative to the connector housing; and wherein the rod has a length and a width with the length being greater than the width and the rod being rotatable around an axis of the length.

A fine pitch adjuster that includes a housing, a wheel gear positioned within the housing and coupled to a ball stud, wherein rotation of the wheel gear provides inward and outward longitudinal translation of the ball stud relative to the housing, and a clutching worm input drive including, an inner drive sleeve having a shaft portion and a head portion, the shaft portion including a plurality of sleeve slots formed therein and a plurality of engagement ribs, and an outer worm gear sleeve having worm gear threads, the worm gear threads coupled at least indirectly to the wheel gear, and an inner chamber, the outer worm gear sleeve including a plurality of grooves extending longitudinally along the inner chamber for mating engagement with the plurality of engagement ribs, wherein rotation of the inner drive sleeve provides clutchable engagement with the outer worm gear sleeve to rotate the wheel gear.

An optical axis adjustment device for a headlamp unit to be mounted in a vehicle is configured to adjust an optical axis of the headlamp unit. The optical axis adjustment device includes an engine temperature acquirer, a displacement amount calculator, and an optical axis adjuster. The engine temperature acquirer is configured to acquire a temperature in an engine compartment of the vehicle. The displacement amount calculator is configured to calculate a displacement amount of the optical axis on a basis of the acquired temperature. The optical axis adjuster is configured to adjust the optical axis of the headlamp unit on a basis of the calculated displacement amount.
