Disclosed are a headlamp optical element, a vehicle lamp module comprising the headlamp optical element, a vehicle lamp, and a vehicle. The headlamp optical element comprises a light collecting portion, a first light emitting portion and a reflecting portion, or comprises the light collecting portion, the first light emitting portion, the reflecting portion and a second light emitting portion. The light collecting portion can converge the incident light and emit the light via the first light emitting portion, with some of the light directly emitted to the second light emitting portion, and the rest of the light being reflected by the reflecting portion and then emitted to the second light emitting portion. The reflecting portion is connected to the lower portion of the first light emitting portion, with a lower beam cut-off line structure being formed at the other end thereof, or the reflecting portion is connected to the upper portion of the first light emitting portion, with a high beam cut-off line structure being formed at the other end thereof. The light emitting surface of the first light emitting portion is formed of multiple step surfaces with segment differences or is a single curved surface.

A headlight of a motor vehicle including a light source and first projection optics, in which each one includes a respective first pair made of one respective first image mask and of one respective first projection lens with a first focal length, which is illuminated by the light source through the one respective image mask. The headlight has two projection optics, in which each one is featuring a respective second pair made of one respective second image mask and of one respective second projection lens with a second focal length, which is illuminated by the light source through the one respective second image mask. The second focal length is greater than the first focal length. An illuminated portion of the first image mask, has a shape of at least a first portion of an overall light distribution of the headlight, and a portion of the second image masks, has a shape of a central portion of the overall light distribution of the headlight.

The present disclosure relates to vehicle lighting devices, and discloses a headlight optical element. The headlight optical element includes a light incident portion, a light transmitting portion and a light emergent portion which are connected in sequence, wherein the light incident portion includes a plurality of light incident surfaces connected sequentially in a left-right direction; the light incident surfaces are curved surfaces protruding backwards in the optical axis direction; and light emergent surfaces are curved surfaces protruding forwards in the optical axis direction. In addition, the present disclosure further discloses a headlight module, a vehicle headlight and a vehicle. The headlight optical element provided by the present disclosure is small in size, high in optical precision, accurate in light pattern, convenient to mount and low in cost.

Provided is a light source device, including: a light-emitting chip arranged on a base plate and configured to emit first light; a light guide rod including first and second light guide portions, the first light guide portion including a light incident end surface, the first light entering the light guide rod through the light incident end surface and being transmitted to the second light guide portion after passing through the first light guide portion, and the second light guide portion including a light-outputting surface for outputting light; a first positioning member including a first groove for accommodating the light guide rod, being directly or indirectly fixed relative to the base plate; and a movable fixing assembly configured to fix, together with the groove of the first positioning member, the light guide rod along a radial direction of the light guide rod, and deforms when fixing the light guide rod.
