[0044] An embodiment of the present application provides a vehicle lamp module, including a lighting module, which includes a light source 100 and a reflective element 200 and a lens 300 arranged in sequence along a light path. The reflective element 200 has a plurality of reflective surfaces 210 corresponding to the light source 100. Light emitted by the light source 100 is reflected by the plurality of reflective surfaces 210 and then emitted by the lens 300 to form a plurality of light type units each having a first boundary. The plurality of light type units are combined to form an illumination light type of the lighting module. The reflective surface 210 has a side 211 for forming a first boundary of the light type unit. The side edges 211 of the plurality of reflective surfaces 210 form an undulating structure so that the plurality of first boundaries in the illumination light type are flush.

[0045] Specifically, Figure 1 and Figure 2 As shown, by arranging the reflective element 200 and the lens 300 in sequence along the light path, the light emitted by the light source 100 can enter the lens 300 after being reflected by the reflective element 200, wherein the reflective element 200 has a plurality of reflective surfaces 210 corresponding to the light source 100, so that the light emitted by the light source 100 is reflected by the plurality of reflective surfaces 210 and then emitted by the lens 300 to form a plurality of light type units each having a first boundary, and the plurality of light type units are combined to form a lighting light type of the lighting module to realize 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 for forming the first boundary of the light type unit. 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 an illumination light type that meets regulatory requirements when the light type units are combined. At this time, the light type unit located in the focal area can be The first boundary of the light type unit formed by reflection of the reflecting surface 210 is used as a reference, and the side edges 211 of the other reflecting surfaces 210 used to form the first boundary of the light type unit are adjusted, so that the side edges 211 of multiple reflecting surfaces 210 form an undulating structure, thereby making the first boundary of the light type unit formed by reflection from other reflecting surfaces 210 aligned with the first boundary of the light type unit formed by reflection from the reflecting surface 210 located in the focal area, that is, making the multiple first boundaries in the lighting light type flush, thereby forming a lighting light type with good brightness and smooth boundaries, meeting regulatory requirements, and making the lighting effect of the car lamp good, thereby effectively ensuring the safety of vehicle driving.

[0046] 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, preferably, the multiple reflective surfaces 210 should be arranged in the horizontal direction, so as to form a narrow and long lighting light type in the horizontal direction to meet the lighting needs of the vehicle. It should also be understood that 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 different sides of the light type unit can be flush.

[0047] 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 a first boundary in the lighting light pattern of the matrix lighting module and the lighting light pattern of the auxiliary lighting module are flush.

[0048] Specifically, the headlight module includes a plurality of lighting modules arranged in a horizontal or vertical 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 horizontal or vertical direction, so that the longitudinal or lateral dimensions of the headlight module are reduced, and the demand for narrow opening light output shape in the headlight market can be met. 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, and can complement each other for the lack of energy at the intervals between different light pattern units, thereby realizing bright and clear headlight lighting. It should also be noted that the first boundary in 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 shape 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 choose different lighting modules according to the actual road conditions.

[0049] 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.

[0050] like Figure 3 and Figure 4As shown, in this embodiment, the vehicle light module includes five lighting modules arranged in a transverse 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 in a transverse direction, and the reflective element 200 of each auxiliary high beam module includes two or one reflective surfaces 210 arranged in a transverse 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, and then adjusts the boundary of the reflective surface 210 close to the light source 100 so that 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 FIG. Figure 5 As shown, it can be seen that the illumination light pattern of the first matrix high beam module 11 is biased to the left of the center line; Figure 6 As shown, the lighting pattern of the second matrix high beam module 12 is closer to the center line than the lighting pattern of the first matrix high beam module 11; Figure 7 As shown, the illumination light pattern of the third matrix high beam module 13 is closer to the center line than the light pattern of the second matrix high beam module 12, such as Figure 8 and Fig. 9 As shown, the lighting pattern of the first auxiliary high beam module 14 and the lighting pattern of the second auxiliary high beam module 15 are located near the center line, but the lighting area is smaller; Fig.10 As shown in FIG, the staggered superposition of the lighting light patterns of the three matrix high beam modules 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; Fig.11 As shown, it is the superposition of the lighting patterns of two auxiliary high beam modules, such as Fig.12 As shown, the headlight pattern is formed by using three matrix high beam modules and two auxiliary high beam modules together. It can be seen that the combination can achieve bright and clear headlight lighting with a large lighting area, which is suitable for lighting under various road conditions.

[0051] Optionally, the longitudinal width of the lens 300 is less than or equal to 20 mm.

[0052] 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 pattern 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 reflective elements 200 are arranged in the transverse direction, and the lenses 300 are arranged in the transverse direction, thereby, the lighting light patterns of 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.

[0053] Optionally, in the matrix lighting module, the light incident surface 310 of the lens 300 is provided with a first pattern structure 311; and / or, in the auxiliary lighting module, the light incident surface 310 of the lens 300 is provided with a first pattern structure 311.

[0054] Specifically, Fig.13 As shown, 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 overlapping of light-type units more uniform, the light incident surface 310 of the lens 300 of the lighting module with 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 with one reflective surface 210 is kept smooth. Among them, the first pattern structure 311 can be a grid pattern, and the size and height of the grid pattern are related to the uniformity when adjacent light-type units are overlapped. The size and height of the grid can be adjusted according to the uniformity when different light-type units are overlapped. In this embodiment, the grid is a rectangular structure with a size of about 2mm×2mm.

[0055] Optionally, a second pattern structure 321 is provided on the light exit surface 320 of the lens 300 .

[0056] Specifically, Fig.14 As shown, the light-emitting surface 320 of the lens 300 can be set to a second pattern structure 321, or can remain smooth. In order to make the high-beam lighting light type in the embodiment of the present application and the low-beam lighting light type in the prior art to be superimposed more smoothly and evenly transition, a second pattern structure 321 can be set on the light-emitting surface 320 of the lens 300. Among them, the second pattern structure 321 can be a horizontal stripe, and the spacing and stripe height of the horizontal stripes should be adjusted according to the uniformity of the transition when superimposed with different low-beam lighting light types.

[0057] It should also be noted that the lens 300 can be made of transparent plastic, commonly PMMA or PC, and is relatively thin overall; Fig.13 and Fig.14 As shown, the light incident surface 310 of each lens 300 is a convex surface, 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, the light incident side of this integrated structure includes multiple convex surfaces arranged in parallel, and the light emitting side includes a plane.

[0058] Optionally, as shown in the figure, multiple lenses 300 with an integrated structure are arranged in a lens holder 400, thereby providing certain support and protection for the lens 300, and at the same time enabling the lens 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.

[0059] Optionally, a matte structure is provided between two adjacent lighting modules.

[0060] Specifically, Fig.15 and Fig.16 As shown, in order to reduce the stray light caused by light crosstalk between the reflective elements 200 of different lighting modules and ensure the independence of the functions of each reflective element 200, a matting structure can be set in the interval between the reflective elements 200 of two adjacent lighting modules to eliminate the stray light. Different matting structures can be used alone or in combination. When using, it is necessary to comprehensively consider the light distribution requirements and the impact on optical performance, so as to select a suitable matting structure.

[0061] Optionally, 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 transverse stripes.

[0062] Alternatively, if Fig.15 As shown, the reflective elements 200 in the multiple lighting modules are in an integrated structure. Since the reflective surface 210 of the reflective element 200 is a clean surface, in order to avoid contamination of the reflective surface 210 when taking or installing the reflective element 200, a pick-up structure 230 is provided on the integrated structure. The pick-up structure 230 is located in the middle of the multiple reflective elements 200, which is convenient for taking the reflective element 200 and does not affect the function of the reflective surface 210. The length of the pick-up structure 230 is in the range of 10-30 mm, the width is in the range of 5-10 mm, and the shape includes but is not limited to a rectangle, a triangle, etc.

[0063] Optionally, the vehicle lamp module further includes a heat sink 500 , the light source 100 and the reflective element 200 are fixed to the heat sink 500 , a first baffle 510 is provided on the heat sink 500 , the first baffle 510 is located between two adjacent lighting modules, and the first baffle 510 extends from the reflective element 200 toward the lens 300 .

[0064] Specifically, Figure 1 and Figure 2 As shown, the headlight module also includes a heat sink 500, which is used 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 heat sink 500, the light sources 100 of multiple lighting modules are all fixed to the heat sink 500, and then the multiple reflective elements 200 in an integrated structure are fixed to the heat sink 500, and by connecting the lens bracket 400 to the heat sink 500, the lenses 300 of multiple lighting modules are also connected to the heat sink 500, thereby improving the connection stability of the headlight module, and the structure is simple, the installation process is simple, the installation efficiency can be improved, and the structural cost and installation cost can be reduced.

[0065] 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 relatively large until it approaches the lens 300. This can effectively avoid mutual light crosstalk between different reflective elements 200 and ensure the optical function of each reflective element 200.

[0066] Alternatively, if Figure 2 As shown, 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 vertical stripes, so as to prevent the light emitted by the light source 100 from being reflected on the first baffle 510 and then reflected twice to cause stray light.

[0067] Alternatively, if Figure 2 As shown, a second baffle 520 is also provided on the heat sink 500, and the second baffle 520 is located in front of the light source 100, so as to block the direct light or large-angle light emitted by the light source 100, avoid the appearance of virtual light at the lower boundary of the illumination light pattern, and enable 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. Among them, the distance from the second baffle 520 to the optical center of the light source 100 is 3mm-10mm, and the height of the second baffle 520 is 0.5mm-2mm higher than the light emitting plane of the light source 100.

[0068] An embodiment of the present application also provides a vehicle lamp, comprising any of the above-mentioned vehicle lamp modules, the vehicle lamp being able to form a vehicle lamp light pattern with good brightness and smooth boundaries, thereby improving the lighting effect and ensuring the safety of vehicle driving.

[0069] An embodiment of the present application also provides a vehicle, comprising any of the above-mentioned headlights, which can form a headlight shape with good brightness and smooth boundaries, thereby improving the lighting effect and ensuring the safety of vehicle driving.
