  • the set widths of the light entry surfaces of the plurality of light gathering units 11 are set as follows: the light entry surfaces of the light gathering units 11 of the outer regions are wide, and the light entry surfaces of the light gathering units 11 of the central region are narrow.
  • the set widths of the light entry surfaces of the plurality of light gathering units 11 decrease from the outer regions to the central region. Specifically, as shown in FIG.
  • the left and right regions of the plurality of the light gathering units 11 are the outer regions, and the middle region is the central region.
  • the set widths of the light entry surfaces of the plurality of light gathering units 11 decrease from the left and right regions to the middle region, so that the high beam shape having the narrower pixel width in a region near straight ahead of a vehicle and the wide pixel width in regions on both sides in front of the vehicle can be formed after the high beam shapes formed by the left and right headlights are superposed.
  • the light-emitting sources 6, corresponding to the right outer region and central region of the plurality of light gathering units 11, of the vehicle high beam module in the left headlight are turned on, so that a light shape having a narrow pixel width in the central region of the light shape and a wide pixel width in the outer region of the light shape (the left region of the light shape) is formed by the left headlight.
  • the light-emitting sources 6, corresponding to the left outer region and central region of the plurality of light gathering units 11, of the vehicle high beam module in the right headlight are turned on, so that a light shape having a narrow pixel width in the central region of the light shape and a wide pixel with in the outer region of the light shape (the right region of the light shape) is formed by the right headlight.
  • the two light shapes are superposed to form a complete high beam shape.
  • the light-emitting sources 6, corresponding to the central regions of the plurality of light gathering units 11, of the vehicle high beam modules in the left and right headlights are all turned on, so that the central regions of the high beam shapes formed by the superimposition of the left and right headlights are superposed, and the high beam shape has higher central brightness.

  • the anteroposterior lengths of the plurality of light gathering units 11 are set as follows: the anteroposterior lengths of the plurality of light gathering units 11 of the outer regions (the left and right regions) are greater, and the anteroposterior lengths of the light gathering units 11 of the central region (the middle region) are less. The anteroposterior lengths of the plurality of light gathering units 11 decrease from the outer regions to the central region.
  • the anteroposterior lengths of the respective light gathering units 11 are different, so that in order to match the second-stage lens with the respective light gathering units 11, the second-stage lens 2 has a certain curvature in the left-right direction. That is, the longitudinal cross-sectional line of the light entry surface of the second-stage lens 2 is a straight line or a backwards protruding curve, and the longitudinal cross-sectional line of the light exit surface of the second-stage lens is a forwards protruding curve, so that the second-stage lens 2 gathers, in the up-down direction, the light emitted by the light gathering units 11, and more light can enter the third-stage lens 3.
  • outer portions of the second-stage lens 2 corresponding to the light gathering units 11 located in the outer regions are forwards bent, so that the light entry surface of the second-stage lens 2 can be close to the light exit surfaces of the light gathering units 11 as much as possible, and more light emitted by the light gathering units 11 enters the second-stage lens 2, thus increasing the utilization rate of light emitted by the light gathering units 11.
  • the curvature of the second-stage lens 2 is close to the curvature of a focal plane of the third-stage lens 3, so that a clear light shape can be formed. It should be noted that the focal plane is theoretically a plane.
  • the focal plane of the third-stage lens 3 actually has a concave spherical curvature. Therefore, if the light exit surface of the second-stage lens 2 is arranged on the curved focal plane, a clearest image can be formed.
  • the second-stage lens 2 may not have a curvature, either, and its light shape effect can also meet the requirement.
  • the width of the second-stage lens 2 in the left-right direction is greater than the width of the first-stage lens 1 in the left-right direction, and the left and right sides of the second-stage lens are both forwards bent, so that the second-stage lens 2 can be applied to both the left headlight and the right headlight, which reduces the mold cost and improves the generality of parts.
  • the respective light-emitting sources 6 are all LED light sources, and are arranged on the focal points of the respective corresponding light gathering units 11.

  • the light-emitting source 6 located on the right side of the optical axis of third-stage lens 30 is arranged on the right side of the optical axis of the corresponding light gathering unit 11
  • the light-emitting source 6 located on the left side of the optical axis of third-stage lens 30 is arranged on the left side of the optical axis of the corresponding light gathering unit 11.
  • the optical axis of the light-emitting source 6 overlaps the optical axis of the corresponding light gathering unit 11, more light emitted by the light-emitting source 6 through the light gathering unit 11 enters the third-stage lens 3, so that the utilization rate of light can be further increased.

  • the low beam auxiliary illumination unit can be arranged above or below or on the left side or on the right side of the second-stage lens 2.

  • the low beam auxiliary illumination unit includes a primary optical element 4 and an auxiliary illumination light source (not shown in the figure) corresponding to the primary optical element 4; and light emitted by the auxiliary illumination light source enters the third-stage lens 3 after passing through the primary optical element 4, so that the third-stage lens 3 can be illuminated.

  • the primary light entry surface 41 is a plane, and the primary light exit surface 42 is a forwards protruding curved surface; an up-down height of the primary light entry surface 41 is greater than an up-down height of the primary light exit surface 42, so that more light enters the primary light entry surface 41; and a left-right width of the primary light entry surface 41 is less than a left-right width of the primary light exit surface 42, which saves materials and reduces the production cost.
  • the primary optical element 4 is provided with the light gathering cup structure 43 on the primary light entry surface 41, so that the light gathering effect is better, and the utilization rate of light is larger.
