[0041] like Figure 2 、 Figure 3 and Figure 4 As shown, the low-beam module includes a low-beam light source, a low-beam primary optical structure, a low-beam secondary optical structure, and a low-beam tertiary optical structure. The low-beam light source emits low-beam light, which is formed by the low-beam primary optical structure and emits a low-beam light pattern with a cutoff line. The low-beam light pattern with a cutoff line passes through the low-beam secondary optical structure and then to the low-beam tertiary optical structure to form the low-beam light pattern. The low-beam primary optical structure includes a low-beam concentrator 1 and a low-beam thick-walled member 2. The low-beam secondary optical structure includes a low-beam imaging lens 3. The low-beam tertiary optical structure includes a low-beam non-imaging lens 4. The low-beam concentrator 1 and the low-beam imaging lens 3 correspond to the low-beam light source. The low-beam concentrator 1 is positioned behind the low-beam thick-walled member 2, the low-beam imaging lens 3 is positioned in front of the low-beam thick-walled member 2, and the low-beam non-imaging lens 4 is positioned in front of the low-beam imaging lens 3. The lower end of the front surface of the low-beam thick-walled member 2 has a structure that forms a low-beam cutoff line. The front surface of the low-beam thick-walled member 2 is located on the focal plane of the low-beam imaging lens group 3. The low-beam imaging lens group 3 is located on the same horizontal plane. The low-beam non-imaging lens 4 has a certain curvature. The size and curvature of the low-beam non-imaging lens 4 are adjustable. Specifically, the size of the low-beam non-imaging lens 4 can be adjusted based on the dimensions of the low-beam primary optical structure and the low-beam secondary optical structure described above. The curvature of the low-beam non-imaging lens 4 can also be freely adjusted to facilitate light diffusion.

[0042] In this embodiment, the low beam light is emitted by the low beam light source in the form of a Lambert distribution, passes through a group of low beam concentrators 1 and a low beam thick-walled part 2, and forms a low beam light pattern with a cut-off line on the front surface of the low beam thick-walled part 2, and finally is emitted through the low beam non-imaging lens 4 to form a complete low beam light pattern on the screen.

[0043] In this embodiment, a set of low-beam concentrators 1 includes four low-beam concentrators connected to a low-beam thick-walled member. A set of low-beam imaging lenses 3 includes four imaging lenses located on the same horizontal plane.

[0044] like Figure 1 As shown, the high beam module is arranged below the low beam module. In one embodiment, the high beam module can also be arranged above the low beam module. Figure 5 This is a schematic diagram of the high-beam module structure, which includes a high-beam light source, a primary high-beam optical structure, and a secondary high-beam optical structure. The high-beam light source emits high-beam light, which is collimated by the primary high-beam optical structure and passes through the secondary high-beam optical structure to form the high-beam light pattern. The primary high-beam optical structure includes a high-beam concentrator 7 and a high-beam thick-walled member 6. Figure 6 It is a schematic diagram of the high beam thick-walled part 6.

The high beam non-imaging lens 5 has a certain curvature. The front surface of the high beam thick-walled part 6 is a row of columnar structures, and the height of the arched surface of the columnar structure can be adjusted. Specifically, the height of the arched surface of the columnar structure can be adjusted as needed. This structure can form a certain degree of diffusion of the light in the horizontal direction, which is beneficial to the uniformity of the overall light pattern.

[0045] In this embodiment, the high beam light is emitted from the high beam light source in the form of a Lambert distribution, forming collimated light in a group of high beam concentrators 7, and the collimated light is emitted through the front surface of the high beam thick-walled part 6, and finally emitted through the high beam non-imaging lens 5 to form a complete high beam light pattern on the screen.

[0046] In this embodiment, a group of high-beam concentrators 7 includes four high-beam concentrators, and the four high-beam concentrators are connected to the high-beam thick-walled member 6 .

[0047] The centers of the high beam light source and the low beam light source are on the same plane, and each light source can be controlled independently. Both the high beam light source and the low beam light source are LED light sources, and are arranged on a circuit board 8. The circuit board 8 is arranged behind the low beam primary optical structure and the high beam primary optical structure, see Figure 1 .

The X direction distance of traditional high and low beam modules is usually between 80mm and 100mm. Figure 8 As shown, the X-direction distance of a traditional high and low beam module is 96.03mm. The X-direction distance of the ultra-narrow lens high and low beam module described in this article is about 50mm. In one embodiment, the X-direction distance of the ultra-narrow lens high and low beam module described in this article is 48.67mm, see Figure 9 It should be understood that the X direction herein is the direction in which light is emitted.
