摘要： A vehicle lamp optical system, a vehicle lamp module, and a vehicle. The vehicle lamp optical system comprises a basic optical subsystem and a catoptric system (3). The basic optical subsystem comprises a light-concentrating element (1) and a collimating optical element (2). The catoptric system (3) comprises a first plane mirror (31) located on a light-exiting optical path of the collimating optical element (2), and/or a second plane mirror (33) located on a light-exiting optical path of the light-concentrating element (1). The mounting position of at least one of the light-concentrating element (1), the collimating optical element (2), the first plane mirror (31), and the second plane mirror (33) can be adjusted, to change the relative positions of at least two of the light-concentrating element (1), the collimating optical element (2), the first plane mirror (31), and the second plane mirror (33) can be changed, so that the light emerging from light-concentrating element (1) is subjected to optical path conversion through the collimating optical element (2) and the catoptric system (3) and is then projected to form a set illuminating light shape. The vehicle lamp optical system is high in spatial layout flexibility, and can thus meet different vehicle lamp models and lamp interior spaces.

摘要： A lamp unit (1) for a vehicle headlamp, the lamp unit comprising: a light-emitting module (10), wherein the light-emitting module (10) is arranged in a vertical direction of a vehicle, the light-emitting module (10) comprises a light emergent surface (100), and light rays that are straight up relative to the vehicle are emitted from the light emergent surface (100) by the light-emitting module (10); and a light ray adjusting device (20), wherein the light ray adjusting device (20) is configured to adjust the light rays emitted from the light emergent surface (100), so as to form a desired shape of light illuminating a road in front of the vehicle. The light ray adjusting device (20) comprises a first reflecting device (201) and a second reflecting device (202), wherein the first reflecting device (201) is configured to adjust emergent light rays of the light emergent surface (100) of the light-emitting module (10) among a plurality of working positions, so as to adjust the position of the light shape in the vertical direction; and the second reflecting device (202) is configured to adjust the emergent light rays of the light emergent surface (100) of the light-emitting module (10) among a plurality of working positions, so as to adjust the position of the light shape in a transverse direction.
