The present disclosure relates to a vehicle lighting system, and discloses a headlight optical element. The headlight optical element includes a light incident portion, a transmission portion and a light emergent portion. The light incident portion includes at least one light incident structure; the transmission portion is arranged between the light incident portion and the light emergent portion, and includes a light transmitting portion located at the center, and light absorbing portions located on the periphery; and the light emergent portion includes a light emergent surface protruding outwards. The headlight optical element has the advantages of simple structure and convenient dimming. The present disclosure further discloses a headlight module adopting the headlight optical element, a vehicle headlight including the headlight module, and a vehicle adopting the vehicle headlight.

A vehicle headlamp is provided, where a high beam module includes a primary optical element (2) and a primary light source (3) located on a back side of the primary optical element (2), and light emitted by the primary light source (3) forms a high beam light shape after passing through the primary optical element (2), where the high beam module is further provided with an auxiliary light source (4) beside the primary light source (3), light emitted by the auxiliary light source (4) forms an auxiliary light shape (6) after passing through the primary optical element (2), and when the low beam module is in a light-emitting state, the auxiliary light source (4) is in a light-emitting state. Beneficial effects: in a low beam lighting mode, a high beam part of the vehicle headlamp remains on, which improves the beauty of the overall appearance of the vehicle headlamp. Moreover, because the brightness of the auxiliary light source (4) is very weak, and does not affect the light intensity and uniformity of low beam light shapes (7 and 8) of a vehicle, other nearby vehicles would not be affected, and thus the driving safety of the vehicles would not be affected.

Provided is an automotive lamp optical element and an automotive headlamp. The automotive lamp optical element includes a light-incident portion, a light-passing portion and a light-emitting portion sequentially connected and integrally formed. The light-incident portion is configured to focus and emit light from a light source into the light-passing portion. The area of a longitudinal section of the light-passing portion gradually increases in an optical axis direction. The light-emitting portion protrudes in a direction facing away from the light-incident portion and is configured to refract light emitted through the light-passing portion.

Provided are an automotive lamp optical element, an automotive lamp module and a vehicle. The automotive lamp optical element includes a light-incident portion, a transmission portion and a light-emitting portion connected in sequence. The light-incident portion is provided with at least one light-incident structure configured to converge light. An area of a cross section of the transmission portion gradually increases in a light transmission direction. A light-emitting convex surface is formed on one end of the light-emitting portion facing away from the transmission portion. The automotive lamp module includes the above automotive lamp optical element, and further includes at least one light source. The at least one light source is disposed in one-to-one correspondence with the at least one light-incident structure.

A system includes an attachment part and a holding element for holding the attachment part on a carrier part, the holding element having a threaded part connected to the attachment part and an internal thread for a holding screw, and a spacer part, the spacer part and the threaded part having interacting threads, the spacer part having a through opening flush with the internal thread of the threaded part when the spacer part is screwed to the threaded part, with the result that the carrier part can be held between a head of the holding screw and the spacer part, the threaded part having a holding section for holding the attachment part, the holding section having at least one latching element which interacts with at least one corresponding latching element of the attachment part for releasably latching the attachment part on the threaded part.

A lamp for a vehicle includes a plurality of optical modules, a first bracket arranged behind the plurality of optical modules, the first bracket performing aiming in a first direction for the plurality of optical modules, and a second bracket arranged between the plurality of optical modules and the first bracket, the second bracket performing aiming in a second direction that is orthogonal to the first direction for each of the plurality of optical modules. In particular, the second bracket is movably coupled to the first bracket to allow each of the plurality of optical modules to be aimed in the second direction as the second bracket moves.

An aiming apparatus for horizontal aim adjustment of a lighting device of a motor vehicle that uses an adjuster that could be broken at a neck recess portion after the horizontal aim is adjusted, thereby reducing the likelihood of any inadvertent change of the horizontal aim without the need for an additional part to cover a head portion of the adjuster.

A torque limiting adjuster for adjusting the position of an adjustable part of a lighting device includes a housing, an output shaft, a driving gear, a driven gear, and a biasing element. The housing includes a main opening and a first threaded portion. The driven gear includes a gearing portion adapted to be engaged with the driving gear. The driving and driven gears are engaged by the biasing element. The output shaft has a first linear guiding portion oriented in a main direction and a second threaded portion coupled with the first threaded portion. The driven gear has a second linear guiding portion slidably coupled with the first linear guiding portion. The second linear guiding portion is configured to transmit the rotation of the driven gear to the first linear guiding portion when the driven gear rotates driven by the driven gear. The driven gear exerts a reaction force on the driving gear that overcomes the biasing element when the driven gear is forced to rotate beyond the predetermined limit position.
