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.

Disclosed is a condenser and a high-and-low-beam integrated vehicle lamp module, the condenser comprises at least one light incident portion, a light-transmitting portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light-transmitting portion; the 50L dark area light shape forming structure protrudes from a surface of the light-transmitting portion and has a slope surface; and the distance from the slope surface to the surface of the light-transmitting portion gradually increases from a position close to the light incident portion to the light emergent portion. Since the 50L dark area light shape forming structure protrudes out of the surface of the light-transmitting portion and has the slope surface, in a high-beam illumination mode, some light is emitted from the 50L dark area light shape forming structure to a 50L test point.

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.

A vehicular headlight (20) includes a first light source unit (41), a second light source unit (61), a temperature sensor (47), and a control unit (110). When the temperature derating is performed on the first light source unit (41) based on the temperature in a state where the light distribution pattern (910) of a low-beam is formed, the control unit (110) controls the power to be supplied to each of a plurality of light-emitting elements (43) so that the light amount of at least a part of the first light with which at least a region (911) of a first light distribution pattern (400) is irradiated decreases as compared with that before the temperature derating.

A light emitting module including a light source and a lens into which a light beam output from the light source is input, through which the light beam passes, and in which the light beam then forms a light distribution pattern and is output, wherein the lens includes a first area that outputs a light beam for forming a first light distribution pattern that is a central portion of the light distribution pattern, and a second area that outputs a light beam for forming a second light distribution pattern that has illuminance lower than that of the first light distribution pattern and is a peripheral portion of the light distribution pattern, and a diffusion angle of the light beam output from the second area in a left-right direction is greater than a diffusion angle of the light beam output from the first area in the left-right direction.

Four of the light-emitting elements are provided at positions that are rotationally symmetric on a circumference centered on the central axis, respectively. The brightness controller faces the one light-emitting element provided at a position on the central axis.
