Abstract (en)
[origin: EP4375567A1] 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.
