An adjuster mechanism includes a housing having a neck and an adjustment shaft extending from the housing. The adjustment shaft is engageable in a reflector of a headlamp. An input shaft extends through the neck of the housing and rotation thereof causes movement of the adjustment shaft. At least one lobe is situated on the input shaft so as to create a non-circular interference fit that establishes a resistance to rotation of the input shaft.

A headlamp adjustment system is applied on a head lamp. The head lamp includes a lens cover, a housing and a reflector. The headlamp adjustment system includes a fixing member, a screw member, a jointing member, a flexible shaft member and a mounting assembly. The fixing member is fixedly disposed on the housing and includes a through hole. The through hole is communicated with a through opening of the housing. The screw member includes a front end and a rear end. The front end is passed through the through opening to be connected to the reflector, and the rear end is passed through the through hole to be exposed out of the housing. The jointing member is connected between the screw member and the flexible shaft member. The mounting assembly is restrictedly disposed in the lens cover and connected to the flexible shaft member.

A ride includes a first device and a second device. The first device has an adjustment mechanism. The second device has an adjustment mechanism. Any one of the first device and the second device is a lighting device in which a direction of a light source of light is adjustable. An opening is formed in the ride. The adjustment mechanism of the first device and the adjustment of the second device can be operated by being accessed from outside through the same opening.

A vehicle lamp includes a substrate, a lens having a pivotal attachment to the substrate and defining a lamp chamber between the lens and the substrate, at least one light source provided in the lamp chamber, an alignment portion integral with and extending from the lens parallel to the substrate and having an aperture, and an adjustment mechanism extending through the aperture and the substrate, the adjustment mechanism configured to adjust alignment of the lens with a single-point adjustment.

A vehicle headlamp optical system, a vehicle headlamp, and a vehicle. The vehicle headlamp optical system comprises a plurality of modules and a light distribution lens that is disposed in front of each module. The plurality of modules comprise at least one high-beam module, at least one main low-beam module, and at least one auxiliary low-beam module. The light distribution lenses are narrow, long light distribution lenses. Each module is disposed at an interval along the length direction of the light distribution lenses. Thus, the miniaturization and diversified design of a vehicle headlamp can be achieved.

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.

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 assembly, a lens unit, a light-shaping plate, a driving rod, and an intermediate plate. The LED light source and the electromagnet are disposed on the heat dissipating device, and the light-shaping plate is rotatably disposed on the electromagnet. The driving rod is disposed between the electromagnet and the light-shaping plate, and 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 intermediate plate is replaceably connected between the lens unit and the heat dissipating device.

A motor vehicle lighting device including: a housing and an outer lens; a light source support in the housing; an optical element; a bearing member fixed to the housing, the optical element being gripped between the light source support and the bearing member; and at least one elastic element gripped between the bearing member and the optical element and configured to be elastically deformable in a direction from the bearing member toward the optical element.

A vehicle light source unit includes an optical supporting portion that supports the optical portion, a metal-made supporting portion, a fixing portion that fixes the metal-made supporting portion and the optical supporting portion in a partial and mutual manner, and a sliding portion that slidably supports the metal-made supporting portion and the optical supporting portion in a partial and mutual manner; the sliding portion is configured in such a way that the metal-made supporting portion and the optical supporting portion can slide on each other in a sliding direction and in such a way as to not only support the optical supporting portion against the metal-made supporting portion but also support the metal-made supporting portion against the optical supporting portion, toward the both sides of a supporting direction that are perpendicular to the sliding direction.

A regulating assembly (1) for a light source and a lighting and/or signaling device, an adjusting device (1200), a lighting device and a motor vehicle, a bezel device (3000), and a gas guiding device and a lighting and/or signaling device containing the same are provided. The regulating assembly (1) and the adjusting device (1200) are used to adjust the lighting and/or signaling module in the lighting device provided in the housing of the lighting device. The bezel device (3000) and the gas guiding device may be used for the lighting and/or signaling device. The regulating assembly (1) comprises a supporting frame (10) coupled in a displaceable manner to the light source, a fixed regulating portion (11) which is rotatable, and horizontal and vertical regulating portions (12,13) in a form of a ball-headed screw-thread part (121). The adjusting device (1200) includes an adjusting screw (1230), a slider (1240) and a base; and the bezel device (3000) includes a top bezel (3100) having a flat plate-like body and a main bezel (3200) including a first bezel (3210) and a second bezel (3220). The gas guiding device comprises a gas channel (5) and a flow guiding component.
