[0004] Headlights play a crucial role in a vehicle's lighting system and performance. They are a crucial component of a vehicle's overall performance and must not only be aesthetically pleasing but also provide excellent illumination. With the rapid development of the automotive industry and user demand for intelligent driver assistance features, adaptive high-beam systems have emerged. These systems are intelligent high-beam control systems that adapt their high beams to road conditions. By disabling or dimming certain high-beam zones, they improve the driver's field of view while preventing glare on illuminated objects.

The positions of different reflective surfaces at a distance from the lens focus are different, so that the boundaries of the light patterns formed by different reflective surfaces are uneven, thereby affecting the lighting effect of the car lights.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0052] An embodiment of the present application provides a vehicle lamp module, as shown in Figures 1, 2 and 15, including a lighting module, which includes a light source 100 and a reflective element 200 and a lens 300 arranged in sequence along the light path. The reflective element 200 has multiple reflective surfaces 210 corresponding to the light source 100. The light emitted by the light source 100 is reflected by the multiple reflective surfaces 210 and then emitted by the lens 300 to form multiple light type units each having a first boundary. The multiple light type units are combined to form an illumination light pattern of the lighting module. The reflective surface 210 has a side 211 configured to form the first boundary of the light type unit. The side edges 211 of the multiple reflective surfaces 210 form an undulating structure so that the multiple first boundaries in the illumination light pattern are flush.

[0053] Specifically, as shown in Figures 1 and 2, by arranging the reflective element 200 and the lens 300 in sequence along the optical path, the light emitted by the light source 100 can be reflected by the reflective element 200 and then enter the lens 300, wherein the reflective element 200 has multiple reflective surfaces 210 corresponding to the light source 100, so that the light emitted by the light source 100 is reflected by the multiple reflective surfaces 210 and then emitted by the lens 300 to form multiple light-type units, each of which has a first boundary. The multiple light-type units are combined to form the lighting light pattern of the lighting module to achieve the lighting of the vehicle lamp. According to optical principles, the size of the reflective surface 210 corresponds to the size of the light-type unit, and the boundary of the reflective surface 210 determines the boundary of the light-type unit. That is, the reflective surface 210 has a side 211 configured to form the first boundary of the light-type unit, so the side 211 determines the first boundary of the light-type unit corresponding to the reflective surface 210 on which it is located. Since the positions of different reflective surfaces 210 from the focal point of the lens 300 are different, the focal point of the lens 300 can only fall on a certain reflective surface 210 or between two adjacent reflective surfaces 210. Therefore, the first boundary of the light type unit formed by different reflective surfaces 210 may be uneven, resulting in the inability to form a lighting light type that meets regulatory requirements when the light type units are combined. At this time, the first boundary of the light type unit formed by the reflective surface 210 located in the focal area can be used as a reference, and the other reflective surfaces 210 can be adjusted to form the side 211 of the first boundary of the light type unit, so that the side edges 211 of multiple reflective surfaces 210 form an undulating structure, and then the first boundary of the light type unit formed by the reflection of the other reflective surfaces 210 is aligned with the first boundary of the light type unit formed by the reflection of the reflective surface 210 located in the focal area, that is, the multiple first boundaries in the lighting light type are aligned, thereby forming a lighting light type with good brightness and smooth boundaries, which meets regulatory requirements and has a good lighting effect of the car light.

[0054] It should be understood that the multiple reflective surfaces 210 should be arranged in the horizontal or vertical direction, and thus the first boundaries of the corresponding multiple light-type units are also arranged in the horizontal or vertical direction, that is, the overall lighting light type is narrow and long in the horizontal or vertical direction. In the embodiment of the present application, the longitudinal direction is the vehicle height direction, and the transverse direction is the vehicle width direction. In order to meet the lighting needs of the vehicle during driving, optionally, the multiple reflective surfaces 210 should be arranged in the transverse direction, thereby forming a narrow and long lighting light type in the transverse direction to meet the lighting needs of the vehicle. It should also be understood that when the opposite sides of the reflective surface 210 are at different distances from the light source 100, the first boundary can be the boundary of the side of the reflective surface 210 close to the light source 100, or it can be the boundary of the side of the reflective surface 210 away from the light source 100. By adjusting the side edges 211 on different sides of the reflective surface 210, the boundaries of the light-type units on different sides can be made flush.

[0055] Optionally, the vehicle light module includes a plurality of lighting modules arranged in a transverse or longitudinal direction, the plurality of lighting modules include a matrix lighting module and an auxiliary lighting module, and the first boundaries of the lighting light patterns of the matrix lighting module and the auxiliary lighting module are flush.

[0056] Specifically, the headlight module includes a plurality of lighting modules arranged in a transverse or longitudinal direction, and the plurality of lighting modules jointly realize the lighting function of the headlight module, and the plurality of lighting modules are arranged in a transverse or longitudinal direction, so that the longitudinal or transverse dimensions of the headlight module are reduced, and the demand of the headlight market for narrow opening light output shape can be met. Among the plurality of lighting modules, the first boundaries of the lighting light patterns of at least some of the lighting modules can be flush. For example, the plurality of lighting modules include a matrix lighting module and an auxiliary lighting module, wherein there are a plurality of matrix lighting modules and at least one auxiliary lighting module, and the lighting light patterns between different lighting modules are staggered and superimposed, which can complement each other in the energy deficiency at the intervals between different light pattern units, thereby realizing bright and clear headlight lighting. It should also be noted that the first boundaries of the lighting light pattern of the matrix lighting module and the lighting light pattern of the auxiliary lighting module should be flush, so that when different lighting modules are used in combination, a light pattern with a flat boundary and a narrow and long narrow pattern can be formed, further improving the lighting effect. It should be understood that the matrix lighting module and the auxiliary lighting module can be used in combination or separately, and the driver can select different lighting modules according to the actual road conditions.

[0057] Optionally, the matrix lighting module is a matrix high beam module, and the auxiliary lighting module is an auxiliary high beam module. The matrix high beam module and the auxiliary high beam module can jointly realize the high beam lighting function of the vehicle light module.

[0058] As shown in Figures 3 and 4, in this embodiment, the headlight module includes five lighting modules arranged along the horizontal direction, of which there are three matrix high beam modules and two auxiliary high beam modules. Specifically, the light source 100 of the lighting module is an LED, and the reflective element 200 of each matrix high beam module includes four or three reflective surfaces 210 arranged along the horizontal direction, and the reflective element 200 of each auxiliary high beam module includes two or one reflective surfaces 210 arranged along the horizontal direction. The light source 100 performs primary energy distribution through the reflective element 200, and then realizes the matrix high beam and auxiliary high beam functions through the lens 300. Then, by adjusting the boundary of the reflective surface 210 close to the side of the light source 100, the lower boundary of the lighting light pattern of each lighting module is flat. At the same time, the lower boundary of the lighting light pattern after the five lighting modules are superimposed should also be flat. Specifically, taking the pixel in the center of the grid as a reference, as shown in FIG5 , it can be seen that the lighting light pattern of the first matrix high beam module 11 is to the left of the center line; as shown in FIG6 , the lighting light pattern of the second matrix high beam module 12 is closer to the center line than the lighting light pattern of the first matrix high beam module 11; as shown in FIG7 , the lighting light pattern of the third matrix high beam module 13 is closer to the center line than the lighting light pattern of the second matrix high beam module 12; as shown in FIG8 and FIG9 , the lighting light pattern of the first auxiliary high beam module 14 and the lighting light pattern of the second auxiliary high beam module 15 are near the center line. The distance between the high beam and the vehicle is close, but the lighting area is small; as shown in Figure 10, the lighting light patterns of the three matrix high beam modules are staggered and superimposed, which can complement the energy deficiency between the different light pattern units, increase the clarity of the lighting light pattern, and also increase the lighting area; as shown in Figure 11, the lighting light patterns of the two auxiliary high beam modules are superimposed, and as shown in Figure 12, the lighting light pattern formed by the use of the three matrix high beam modules and the two auxiliary high beam modules is shown. It can be seen that the combination can achieve bright and clear lighting, a large lighting area, and is suitable for lighting under various road conditions.

[0059] Optionally, the longitudinal width of the lens 300 is less than or equal to 20 mm.

[0060] Specifically, it can be seen from the above that by arranging multiple reflecting surfaces 210 in the transverse direction, the headlight light pattern obtained by superimposing the lighting light patterns of each lighting module can be narrow and long. Therefore, the lens 300 can be designed as a narrow and long lens 300 with a small longitudinal width and a large transverse width, which can not only meet the requirements of the light pattern and brightness of the headlight, but also reduce the occupied space. In the embodiment of the present application, the longitudinal width of the lens 300 is less than or equal to 20 mm. It should also be understood that by arranging multiple lighting modules in the transverse direction, that is, the light sources 100 of different lighting modules are arranged in the transverse direction, the reflecting elements 200 are arranged in the transverse direction, and the lenses 300 are arranged in the transverse direction, the lighting light patterns of the multiple lighting modules can be made into a narrow and long light pattern together, and the entire headlight module is also flat in the longitudinal direction, which can not only reduce the installation space, but also meet the demand of the headlight market for narrow opening shapes.

[0061] Optionally, the light incident surface 310 of the lens 300 in the matrix lighting module is provided with a first pattern structure 311 ; and / or, the light incident surface 310 of the lens 300 in the auxiliary lighting module is provided with a first pattern structure 311 .

[0062] Specifically, as shown in FIG13 , the light incident surface 310 of the lens 300 can be set to a first pattern structure 311 or can remain smooth. In order to make the boundary transition between adjacent light-type units smoother and the superposition of light-type units more uniform, the light incident surface 310 of the lens 300 of the lighting module having multiple reflective surfaces 210 can be provided with a first pattern structure 311; in order to ensure the maximum brightness of the light-type unit, the light incident surface 310 of the lens 300 of the lighting module having one reflective surface 210 is kept smooth. Among them, the first pattern structure 311 can be a grid pattern. The size and height of the grid pattern are related to the uniformity of the superposition between adjacent light-type units. The size and height of the grid can be adjusted according to the uniformity of the superposition of different light-type units. In this embodiment, the grid is a rectangular structure with a size of approximately 2 mm × 2 mm.

[0063] Optionally, a second pattern structure 321 is provided on the light exit surface 320 of the lens 300 .

[0064] Specifically, as shown in Figure 14 , the light-emitting surface 320 of the lens 300 can be provided with a second patterned structure 321, or it can remain smooth. To ensure a smoother and more uniform transition between the high-beam lighting pattern in the present embodiment and the low-beam lighting pattern in the prior art, the light-emitting surface 320 of the lens 300 can be provided with a second patterned structure 321. The second patterned structure 321 can be horizontal stripes, with the spacing and height of the horizontal stripes adjusted to ensure uniformity of the transition when superimposed with different low-beam lighting patterns.

[0065] It should also be noted that the lens 300 can be made of transparent plastic, commonly PMMA or PC, and is relatively thin overall; as shown in Figures 13 and 14, the light incident surface 310 of each lens 300 is a convex surface, and the light emitting surface 320 of each lens 300 is a plane, and the lenses 300 in multiple lighting modules should be an integrated structure, and the light incident side of this integrated structure includes multiple convex surfaces arranged in parallel, and the light emitting side includes a plane.

[0066] Optionally, as shown in FIG1 , a plurality of lenses 300 in an integrated structure are arranged in a lens holder 400 , thereby providing certain support and protection for the lenses 300 , and enabling the lenses 300 and the lens holder 400 to be installed in combination with other components, thereby improving the connection stability of the headlight module, and also making the installation process simpler and improving the installation efficiency.

[0067] Optionally, a light extinction structure is provided between two adjacent lighting modules.

[0068] Specifically, as shown in Figures 15 and 16 , to reduce stray light caused by light crosstalk between reflective elements 200 in different lighting modules and ensure the functional independence of each reflective element 200, a matte structure can be installed in the space between the reflective elements 200 of two adjacent lighting modules to eliminate stray light. Different matte structures can be used individually or in combination. When selecting a suitable matte structure, it is necessary to comprehensively consider the light distribution requirements and the impact on optical performance.

[0069] Optionally, as shown in FIG15 , the matte structure includes but is not limited to ribs 221 , grooves 222 and a third pattern structure 223 , wherein the third pattern structure 223 includes but is not limited to vertical stripes and / or transverse stripes.

[0070] Optionally, as shown in FIG15 , the reflective elements 200 in the multiple lighting modules are integrated. Since the reflective surface 210 of the reflective element 200 is a clean surface, a pick-up structure 230 is provided on the integrated structure to prevent contamination of the reflective surface 210 when removing or installing the reflective element 200. The pick-up structure 230 is located in the middle of the multiple reflective elements 200 to facilitate removal of the reflective element 200 without affecting the function of the reflective surface 210. The pick-up structure 230 has a length ranging from 10 to 30 mm and a width ranging from 5 to 10 mm, and its shape includes but is not limited to a rectangle, a triangle, etc.

[0071] Optionally, the headlight module also includes a radiator 500, the light source 100 and the reflective element 200 are fixed to the radiator 500, and a first baffle 510 is provided on the radiator 500. The first baffle 510 is located between two adjacent lighting modules and extends from the reflective element 200 toward the lens 300.

[0072] Specifically, as shown in Figures 1 and 2, the headlight module also includes a radiator 500, which is configured to achieve the heat dissipation function of the headlight module. The headlight module also includes a circuit board 600, which is connected to the light source 100 to achieve the light emission of the light source 100. By fixing the circuit board 600 to the radiator 500, the light sources 100 of multiple lighting modules are all fixed to the radiator 500, and then the multiple reflective elements 200 with an integrated structure are fixed to the radiator 500, and by connecting the lens bracket 400 to the radiator 500, the lenses 300 of multiple lighting modules are also connected to the radiator 500, thereby improving the connection stability of the headlight module, and the structure is simple, the installation process is simple, and the installation efficiency can be improved, and the structural cost and installation cost can be reduced.

[0073] It should also be noted that in order to better meet the independent optical functions of each reflective element 200 and prevent the light of the same reflective element 200 from causing stray light due to light crosstalk, a first baffle 510 can be set on the heat sink 500. The first baffle 510 is located between two adjacent lighting modules. The first baffle 510 extends from the reflective element 200 toward the lens 300. The extension length of the first baffle 510 should be large, until it approaches the lens 300, thereby effectively avoiding mutual light crosstalk between different reflective elements 200 and ensuring the optical function of each reflective element 200.

[0074] Optionally, as shown in FIG2 , a fourth pattern structure 511 is provided on the surface of the first baffle 510 , and the fourth pattern structure 511 includes but is not limited to serrated stripes and / or vertical stripes, thereby preventing the light emitted by the light source 100 from being reflected on the first baffle 510 and then being reflected twice to cause stray light.

[0075] Optionally, as shown in FIG2 , a second baffle 520 is further provided on the heat sink 500 . The second baffle 520 is located in front of the light source 100 , thereby blocking direct light or large-angle light emitted by the light source 100 , avoiding the occurrence of false light at the lower boundary of the illumination light pattern, and allowing the effective light of the light source 100 to fully pass through the reflective element 200 for energy distribution, thereby forming a bright and clear light pattern. The distance between the second baffle 520 and the optical center of the light source 100 is 3 mm to 10 mm, and the height of the second baffle 520 is 0.5 mm to 2 mm higher than the light emitting plane of the light source 100 . In other words, the direction perpendicular to the light emitting plane of the light source is taken as the first direction (e.g., the longitudinal direction mentioned above). In the first direction, the distance between the side of the second baffle facing away from the light source (e.g., the top side of the second baffle in FIG2 ) and the light emitting plane of the light source is 0.5 mm to 2 mm.

[0077] An embodiment of the present application also provides a vehicle, comprising any of the headlights described above, which can form a headlight pattern with good brightness and smooth boundaries, thereby improving the lighting effect.
