[0031] Compared with related technologies, the beneficial effects of the technical solution of this application are as follows:
[0032] The headlight module includes a low beam module, a high beam module, and an outer lens. The low beam module comprises a first light source module and a first inner lens module.

The focal point of the outer lens is located in both the first and second regions, forming a low beam pattern based on the first light pattern and projecting the low beam into a third region, and forming a high beam pattern based on the second light pattern and projecting the high beam pattern into a fourth region. Therefore, this headlight module is an integrated high and low beam module. The low beam pattern is projected based on the first light pattern formed by the low beam module, and the high beam pattern is projected based on the second light pattern formed by the high beam module. The high and low beam patterns do not require physical baffles, eliminating the problem of dark gaps and preventing energy loss due to baffles, thus ensuring illumination brightness and overall lighting effect. Meanwhile, the headlight module eliminates the physical light pattern baffle and simplifies the structure of the headlight module.
[0033] In addition, the fourth region covers at least part of the third region. That is to say, the high beam pattern projected by the outer lens can cover at least part of the low beam pattern. In other words, the high beam pattern and the low beam pattern can overlap, which can improve the lighting brightness and thus improve the lighting effect. Attached Figure Description

[0055] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0056] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0057] As described in the background section, for integrated high and low beam headlight modules, there is a noticeable dark line at the junction of the high and low beams, affecting the illuminated area and road visibility, resulting in poor lighting performance. Figure 1 As shown, Figure 1 This is a schematic diagram of a conventional integrated high and low beam vehicle headlight module. The module includes: a low beam unit 10, a high beam unit 20, an outer lens 30, and a light pattern baffle 40. The light pattern baffle 40 is used to separate the high and low beams and to form a light pattern cutoff line. Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 These are all schematic diagrams of the superimposed high and low beam light patterns of the aforementioned headlight modules. Due to the presence of the light pattern baffle 40, there will be a dark gap between the low beam light pattern and the high beam light pattern. Furthermore, since the light pattern baffle 40 is a solid baffle, the dark gap between the low beam and the high beam can only be reduced as much as possible, but cannot be eliminated.
[0058] In addition, such as Figure 4 and Figure 5 As shown, Figure 4 The above diagram illustrates the low beam pattern of the headlight module. Figure 5 This is a schematic diagram of the high beam pattern of the aforementioned headlight module. Figure 4 and Figure 5 It can be seen that the light pattern boundaries of the high beam and low beam of the above-mentioned headlight module are caused by the light pattern baffle 40. As a result, some energy is lost due to the blocking of the high beam and low beam by the light pattern baffle 40, which affects the lighting brightness and thus the lighting effect.
[0059] Based on the above, this application provides a vehicle lighting module, such as... Figure 6 As shown, the headlight module includes: a low beam module 100, a high beam module 200, and an outer lens 300. Figure 6 In the middle, O1 represents the focal point of the outer lens 300. Figure 6The second direction is perpendicular to the plane containing the first and third directions. The first direction is parallel to the direction from the low beam module 100 to the high beam module 200, and the third direction is parallel to the direction from the low beam module 100 and the high beam module 200 to the outer lens 300.
[0060] The low beam module 100 includes a first light source module 110 and a first inner lens module 120. The first light source module 110 is used to emit a low beam, and the first light source module 110 is located at the focal point of the first inner lens module 120, that is, the first light source module 110 is located on the light-incident side of the first inner lens module 120 and at the focal point of the first inner lens module 120. The first inner lens module 120 forms a first light pattern based on the low beam and projects the low beam onto a first region, that is, forms a first light pattern in the first region.
[0061] The high beam module 200 includes a second light source module 210 and a second inner lens module 220. The second light source module 210 emits a high beam and is located at the focal point of the second inner lens module 220, that is, the second light source module 210 is located on the light-incident side of the second inner lens module 220 and at the focal point of the second inner lens module 220. The second inner lens module 220 forms a second light pattern based on the high beam and projects the high beam onto a second region, that is, forms a second light pattern in the second region.
[0062] The low beam module 100 is located on the incident light side of the outer lens 300, and the focal point of the outer lens 300 is located in the first region. The outer lens 300 is used to form a low beam pattern based on the first beam pattern and project the low beam into the third region, that is, the outer lens 300 can form a low beam pattern in the third region based on the first beam pattern. The third region is located on the emitting light side of the outer lens 300, and the low beam pattern is an inverted image of the first beam pattern formed by the outer lens 300. It should be noted that since the focal point of the outer lens 300 is located in the first region, the first inner lens module 120 can form the first beam pattern at the focal point of the outer lens 300. Furthermore, since the first inner lens module 120 forms the first beam pattern at the focal point of the outer lens 300, according to the imaging principle, as... Figure 7 As shown, Figure 7 Image (a) is a schematic diagram of the first light pattern. Figure 7 (b) is a schematic diagram of the near beam pattern. The outer lens 300 can project the first beam pattern formed in the first region and form an inverted image of the first beam pattern in the third region, and then form the near beam pattern in the third region.
[0063] The high beam module 200 is located on the incident light side of the outer lens 300, and the focal point of the outer lens 300 is also located in the second region. The outer lens 300 can form a high beam pattern based on the second light pattern and project the high beam pattern onto the fourth region, that is, form a high beam pattern in the fourth region. The fourth region is located on the emitting light side of the outer lens 300, and the fourth region covers at least part of the third region. The high beam pattern is an inverted image of the second light pattern formed by the outer lens 300. It should be noted that, since the focal point of the outer lens 300 is located in the second region, the second inner lens module 220 can form a second light pattern at the focal point of the outer lens 300. Furthermore, since the second light pattern is formed at the focal point of the outer lens 300, according to the imaging principle, as... Figure 8 As shown, Figure 8 (a) is a schematic diagram of the second light pattern. Figure 8 (b) is a schematic diagram of the high beam pattern. The outer lens 300 can project the first beam pattern formed in the first region and form an inverted image of the first beam pattern in the third region, and then form a near beam pattern in the third region.
[0064] As described above, the first inner lens module 120 of the low beam module 100 can form a first light pattern at the focal point of the outer lens 300 based on the low beam emitted from the first light source module 110. The first light pattern is inverted from the low beam pattern, allowing the outer lens 300 to project the low beam into a third region, forming a low beam pattern in that region. In other words, the low beam pattern is projected from the first light pattern formed by the low beam module 100. Similarly, the second inner lens module 220 of the high beam module 200 can form a second light pattern at the focal point of the outer lens 300 based on the high beam emitted from the second light source module 210. This second light pattern is inverted from the low beam pattern, allowing the outer lens 300 to project the high beam into a fourth region, forming a high beam pattern in that region. In other words, the high beam pattern is projected from the second light pattern formed by the high beam module 200.
[0065] Therefore, it can be seen that this headlight module is an integrated high and low beam headlight module. The low beam pattern is projected based on the first beam pattern formed by the low beam module 100, and the high beam pattern is projected based on the second beam pattern formed by the high beam module 200, as shown below. Figure 7 (b) and Figure 8 As shown in (b), the beam patterns for both high and low beams do not require a physical baffle, eliminating the problem of dark gaps. Furthermore, no energy is lost due to the baffle's obstruction, ensuring illumination brightness and thus guaranteeing the lighting effect. Additionally, this headlight module eliminates the need for a physical baffle, simplifying its structure.
[0066] Furthermore, as can be seen from the above, the fourth region covers at least part of the third region. In other words, the high beam pattern projected by the outer lens 300 can cover at least part of the low beam pattern; that is, the high beam pattern and the low beam pattern can overlap. Figure 9 As shown, this is to increase the brightness of the lighting, thereby improving the lighting effect.
[0067] It should be noted that the first light source module 110 is located at the focal point of the first inner lens module 120, and the near beam emitted by the first light source module 110 is converged at the focal point of the outer lens 300 by the first inner lens module 120. The second light source module 210 is located at the focal point of the second inner lens module 220, and the far beam emitted by the second light source module 210 is converged at the focal point of the outer lens 300 by the second inner lens module 220.
[0068] In one embodiment of this application, such as Figure 10 and Figure 11 As shown, the first light source module 110 includes multiple first light sources 111, each of which emits a first beam. The aforementioned low beam is composed of the first beam emitted by each of the multiple first light sources 111, that is, the low beam is composed of multiple first beams.
[0069] The first inner lens module 120 includes a plurality of first inner lenses 121, each corresponding to a plurality of first light sources 111, with each first light source 111 located at the focal point of the first inner lens 121. The first inner lens 121 forms a first sub-light pattern based on a corresponding first beam and projects the first beam onto a first region. The first light pattern is composed of a combination of multiple first sub-light patterns; that is, the first light pattern is formed by a combination of multiple first sub-light patterns formed by the corresponding first light sources 111 and the first inner lenses 121. It should be noted that the first inner lens 121 forming a first sub-light pattern based on a corresponding first beam means that the first inner lens 121 forms a first sub-light pattern based on the first beam emitted by the corresponding first light source 111.
[0070] As described above, the first light pattern is composed of multiple first sub-light patterns, allowing for precise adjustment of the first light pattern via the first light source 111 and the first inner lens 121. This, in turn, enables precise adjustment of the low beam pattern, allowing the headlight module to output a low beam pattern that meets design requirements. Furthermore, the combination of multiple first sub-light patterns also allows for shape adjustment of the low beam pattern via the first light source 111 and the first inner lens 121, achieving diversification of the low beam pattern to meet various application scenarios and demonstrating strong practicality.
[0071] In one embodiment of this application, such as Figure 10 and Figure 11 As shown, the second light source module 210 includes multiple second light sources 211, each of which emits a second beam. The aforementioned high beam is composed of a combination of the second beams emitted by the multiple second light sources, i.e., the aforementioned high beam is composed of a combination of multiple second beams.
[0072] The second inner lens module 220 includes a plurality of second inner lenses 221, each corresponding to a plurality of second light sources 211. Each second inner lens 221 forms a second light pattern based on a corresponding second beam, that is, the second inner lens 221 forms a second sub-light pattern based on the second beam emitted by the corresponding second light source 211, and projects the second beam onto a second region. The second light pattern is composed of a combination of multiple second sub-light patterns, specifically, the second light pattern is formed by a combination of multiple second sub-light patterns formed by the corresponding second light sources 211 and second inner lenses 221.
[0073] As can be seen from the above, the second light pattern is composed of multiple second sub-light patterns. Thus, the second light pattern can also be precisely adjusted through the second light source 211 and the second inner lens 221, thereby achieving precise adjustment of the high beam pattern. This allows the vehicle headlight module to output a high beam pattern that meets the design requirements and to adjust the shape of the high beam pattern, achieving diversification of the high beam pattern, meeting different application scenarios, and demonstrating strong practicality.
[0074] In one embodiment of this application, such as Figure 10 and Figure 11 As shown, the first inner lens module 120 and the second inner lens module 220 are adjacent and arranged along the first direction. It should be noted that... Figure 10 and Figure 11 The third direction is perpendicular to the plane containing the first and second directions.
[0075] Based on the above, the light-incident surface of the first inner lens module 120 is a plane extending along the second direction, and the light-exit surface of the first inner lens module 120 is a curved surface convex relative to the light-incident surface. The first direction and the second direction are parallel to the mounting surface of the first inner lens module 120, and the first direction and the second direction are perpendicular to each other.
[0076] The light-incident surface of the second inner lens module 220 is a plane extending along the second direction, and the light-exit surface of the second inner lens module 220 is a curved surface convex relative to the light-incident surface. The first and second directions are also parallel to the mounting surface of the second inner lens module 220; that is, the mounting surface of the first inner lens module 120 and the mounting surface of the second inner lens module 220 are parallel. It should be noted that the first inner lens module 120 and the second inner lens module 220 are integrally formed, or they can be two separate inner lenses, depending on the specific situation.
[0077] The focal point of the light-emitting surface of the first inner lens module 120 coincides with the focal point of the outer lens 300, so that the first inner lens module 120 can project a near-light beam onto the first region where the focal point of the outer lens 300 is located. The focal point of the light-emitting surface of the second inner lens module 220 coincides with the focal point of the outer lens 300, so that the second inner lens module 220 can project a far-light beam onto the second region where the focal point of the outer lens 300 is located.
[0078] It should be noted that the light-incident surface of the first inner lens module 120 is a plane extending along the second direction, and the light-exiting surface of the first inner lens module 120 is a curved surface convex relative to the light-incident surface. Therefore, the first light source module 110 is located at the focal point of the light-exiting surface of the first inner lens module 120, that is, the first light source module 110 is located at one side focal point of the light-exiting surface of the first inner lens module 120, and the other side focal point of the light-exiting surface of the first inner lens module 120 coincides with the focal point of the light-incident side of the outer lens 300. Similarly, the light-incident surface of the second inner lens module 220 is a plane extending along the second direction, and the light-exiting surface of the second inner lens module 220 is a curved surface convex relative to the light-incident surface. Therefore, the second light source module 210 is located at the focal point of the light-exiting surface of the second inner lens module 220, that is, the second light source module 210 is located at one side focal point of the light-exiting surface of the second inner lens module 220, and the other side focal point of the light-exiting surface of the second inner lens module 220 coincides with the focal point of the light-incident side of the outer lens 300. It should also be noted that the light-incident surface of the first inner lens module 120 is a plane extending along the second direction, so that the near beam emitted by the first light source module 110 enters through the light-incident surface of the first inner lens module 120 without changing its transmission path. That is, the near beam emitted by the first light source module 110 only converges near the focal point of the outer lens 300 through the light-outceasing surface of the first inner lens module 120. Fewer factors affect the transmission path of the near beam, making its transmission easier to control, thus facilitating the adjustment of the near beam pattern. Similarly, the light-incident surface of the second inner lens module 220 is a plane extending along the second direction, resulting in fewer factors affecting the transmission path of the high beam, making its transmission easier to control, and thus facilitating the adjustment of the high beam pattern.
[0079] In one embodiment of this application, such as Figure 11 As shown, along the second direction, the width of the first inner lens module 120 is equal at all points, the width of the first inner lens module 120 is the width along the second direction, and the plurality of first inner lenses 121 include a first sub-inner lens 1211, a second sub-inner lens 1212 and a third sub-inner lens 1213 arranged along the second direction.
[0080] The plurality of first light sources 111 include a first sub-light source 1111, a second sub-light source 1112, and a third sub-light source 1113 (e.g., arranged along the second direction) Figure 11(The red square in the middle) The first sub-inner lens 1211 corresponds to the first sub-light source 1111, the second sub-inner lens 1212 corresponds to the second sub-light source 1112, and the third sub-inner lens 1213 corresponds to the third sub-light source 1113. The emitting surface of the second sub-light source 1112 is smaller than the emitting surface of the third sub-light source 1113, and the emitting surface of the second sub-light source 1112 is concave relative to the emitting surface of the third sub-light source 1113.
[0081] like Figure 12 As shown, the low beam pattern includes a fifth region 5 along the second direction (e.g., Figure 13 As shown), the sixth region 6 (as shown) Figure 14 (as shown) and the seventh region 7 (as shown) Figure 15 As shown, region 5 corresponds to the first sub-inner lens 1211, region 6 corresponds to the second sub-inner lens 1212, and region 7 corresponds to the third sub-inner lens 1213. Specifically, region 5 is formed by the first sub-beam pattern projected from the first light beam emitted by the first sub-light source 1111 in the first region, projected by the outer lens 300; region 6 is formed by the first sub-beam pattern projected from the second sub-light source 1112 in the first region, projected by the outer lens 300; and region 7 is formed by the first sub-beam pattern projected from the third sub-light source 1113 in the first region, projected by the outer lens 300. Based on the above, region 6 is smaller than region 7, and along the second direction, region 6 is concave relative to region 7. It should be noted that the focal point of the first inner lens module 120 coincides with the focal point of the outer lens 300. According to the imaging principle, the light pattern of the near beam emitted from the first inner lens module 120 is inverted with the first light pattern of the first region, and the first light pattern is inverted with the near beam pattern. Therefore, the light pattern of the near beam emitted from the first inner lens module 120 is the same as the near beam pattern. Thus, the emitting surface of the second sub-light source 1112 is smaller than the emitting surface of the third sub-light source 1113, and the emitting surface of the second sub-light source 1112 is concave relative to the emitting surface of the third sub-light source 1113. Therefore, the sixth region is smaller than the seventh region, and along the second direction, the sixth region is concave relative to the seventh region.
[0082] As described above, since the emitting surface of the second sub-light source 1112 is smaller than that of the emitting surface of the third sub-light source 1113, and along the second emission direction, the emitting surface of the second sub-light source 1112 is concave relative to the emitting surface of the third sub-light source 1113, correspondingly, the sixth region is smaller than the seventh region, and along the second emission direction, the sixth region is concave relative to the seventh region. Therefore, for the vehicle headlight module provided in this application, the first light pattern can be controlled by adjusting the size of the emitting surface of each first light source 111 in the first light source module 110 and the relative position between each first light source 111, thereby achieving precise adjustment of the low beam pattern. This allows the vehicle headlight module to output a low beam pattern that meets design requirements and to achieve shape adjustment of the low beam pattern, realizing diversification of the low beam pattern and meeting different application scenarios, thus demonstrating strong practicality.
[0083] In one embodiment of this application, the width of the second sub-inner lens 1212 along the second direction is equal to the width of the first sub-inner lens 1211 along the second direction, and the width of the second sub-inner lens 1212 along the second direction is less than the width of the third sub-inner lens 1213 along the second direction. Correspondingly, the width of the sixth region along the second direction is equal to the width of the fifth region along the second direction, and the width of the sixth region along the second direction is less than the width of the seventh region along the second direction. That is, the width of the sixth region corresponding to the second sub-inner lens 1212 along the second direction is equal to the width of the fifth region corresponding to the first sub-inner lens 1211 along the second direction, and the width of the sixth region corresponding to the second sub-inner lens 1212 along the second direction is less than the width of the seventh region corresponding to the third sub-inner lens 1213 along the second direction. Therefore, the headlight module provided in this application can also achieve the control of the first light pattern by adjusting the size of multiple first inner lenses 121, thereby achieving precise adjustment of the low beam pattern. This allows the headlight module to output a low beam pattern that meets the design requirements, as well as to achieve shape adjustment of the low beam pattern, thus realizing the diversification of the low beam pattern and meeting different application scenarios, making it highly practical.
[0084] In one embodiment of this application, such as Figure 11 As shown, the light-emitting surfaces of the plurality of first light sources 111 are square, and the central axis of the light-emitting surface of the first sub-light source 1111 among the plurality of first light sources 111 has a preset angle A with the second direction, the value of the preset angle A being greater than 0. It should be noted that the preset angle A between the central axis of the light-emitting surface of the first sub-light source 1111 and the second direction can be achieved by rotating the first sub-light source 1111.
[0085] Accordingly, such as Figure 12 and Figure 13 As shown, Figure 13This is a schematic diagram of the beam pattern in the fifth region. There is a preset angle A between the fifth region and the sixth region. That is, the side of the fifth region adjacent to the sixth region has an angle of inclination. This angle of inclination is equal to the preset angle A. The value of the preset angle A can be 15° or 45°, etc., to meet the requirements of the right cutoff line shape of the low beam at 15°, 45°, etc., and thus obtain a low beam pattern that meets the requirements.
[0086] In one embodiment of this application, such as Figure 11 As shown, along the third direction, the center of the light-incident surface of the third sub-inner lens 1213 coincides with the center of the light-outcident surface, and the light-outcident surface of the third sub-inner lens 1213 is symmetrical with respect to the plane containing the center of the light-incident surface. The third direction is parallel to the direction from the light-incident surface of the first inner lens module 120 to the light-outcident surface. The plane containing the center of the light-incident surface of the third sub-inner lens 1213 is parallel to the third direction, and the plane containing the center of the light-incident surface of the third sub-inner lens 1213 is perpendicular to the second direction.
[0087] Along the second direction, the light-emitting surface of the third sub-light source 1113 includes a first part 1 and a second part 2. The first part 1 and the second part 2 are located on opposite sides of the plane where the center of the light-incident surface of the third sub-inner lens 1213 is located. Along the second direction, the distance between the center of the light-incident surface of the third sub-inner lens 1213 and the edge of the first part 1 is less than the distance between the center of the light-incident surface of the third sub-inner lens 1213 and the edge of the first part 1 is less than the distance between the center of the light-incident surface of the third sub-inner lens 1213 and the edge of the second part 2. In other words, the area of the first part 1 is less than the area of the second part 2. That is, the light-emitting surface of the third sub-light source 1113 is asymmetrically distributed relative to the plane where the center of the light-incident surface of the third sub-inner lens 1213 is located. Most of the light-emitting surface of the third sub-light source 1113 is located on one side of the plane where the center of the light-incident surface of the third sub-inner lens 1213 is located, and the remaining part is located on the other side of the plane where the center of the light-incident surface of the third sub-inner lens 1213 is located.
[0088] like Figure 15 As shown, Figure 13 This is a schematic diagram of the light pattern in the seventh region, which includes part 3 and part 4. Part 3 corresponds to part 1, and part 4 corresponds to part 2. The brightness of part 3 is greater than that of part 4.
[0089] Based on the above, the distance between the projection of the center of the incident surface of the third sub-inner lens 1213 along the third direction and the edge of the first part 1 is less than the distance between it and the edge of the second part 2. Since the centers of the incident and exit surfaces of the third sub-inner lens 1213 coincide, that is, the distance between the projection of the center of the exit surface of the third sub-inner lens 1213 along the third direction and the edge of the first part 1 is less than the distance between it and the edge of the second part 2. Furthermore, since the exit surface of the third sub-inner lens 1213 is a curved surface convex relative to the incident plane, the magnification effect of the exit surface of the third sub-inner lens 1213 on the emitting surface of the first beam gradually increases along the direction from the center of the exit surface of the third sub-inner lens 1213 to the edge. It is known that the distance between the projection of the center of the incident surface of the third sub-inner lens 1213 along the third direction and the edge of the first part 1 is less than the distance between it and the edge of the second part 2, that is, the magnification effect of the exit surface of the third sub-inner lens 1213 on the first part 1 is less than the magnification effect on the second part 2, thus the third part 3 is smaller than the fourth part 4. Furthermore, due to the magnification effect of the light-emitting surface of the third sub-inner lens 1213 on the light-emitting surface of the first beam, as the light-emitting surface of the first beam is magnified, the energy density of the first beam after passing through the third sub-inner lens 1213 will gradually decrease, and the brightness will become lower. Therefore, the distance between the projection of the center of the light-incident surface of the third sub-inner lens 1213 along the third direction and the edge of the first part 1 is less than the distance between the center and the edge of the second part 2. The magnification effect of the light-emitting surface of the third sub-inner lens 1213 on the first part 1 is less than the magnification effect on the second part 2. As a result, the energy density of the third part 3 is greater than the energy density of the fourth part 4, and consequently, the brightness of the third part 3 is greater than the brightness of the fourth part 4.
[0090] In one embodiment of this application, such as Figure 10 and Figure 11 As shown, the second inner lens module 220, i.e., a plurality of second inner lenses 221, includes a fourth sub-inner lens 2211, a fifth sub-inner lens 2212, and a sixth sub-inner lens 2213 arranged along the second direction. The fourth sub-inner lens 2211, the fifth sub-inner lens 2212, and the sixth sub-inner lens 2213 have the same shape and size, and the width of the second inner lens module 220 along the second direction is equal at all points.
[0091] The second light source module 210, i.e., multiple second light sources 211, includes a fourth sub-light source 2111, a fifth sub-light source 2112, and a sixth sub-light source 2113 arranged along the second direction. The fourth sub-light source 2111 corresponds to the fourth sub-inner lens 2211, the fifth sub-light source 2112 corresponds to the fifth sub-inner lens 2212, and the sixth sub-light source 2113 corresponds to the sixth sub-inner lens 2213. The light-emitting surfaces of the fourth sub-light source 2111, the fifth sub-light source 2112, and the sixth sub-light source 2113 are equal, and the centers of the light-emitting surfaces of the fourth sub-light source 2111, the fifth sub-light source 2112, and the sixth sub-light source 2113 are located on the same straight line along the second direction.
[0092] Accordingly, such as Figure 16 As shown, the second light pattern along the second direction includes an eighth region 8, a ninth region 9, and a tenth region 10. The eighth region 8 corresponds to the fourth sub-inner lens 2211, the ninth region 9 corresponds to the fifth sub-inner lens 2212, and the tenth region 10 corresponds to the sixth sub-inner lens 2213. The eighth region 8, the ninth region 9, and the tenth region 10 have the same shape and size, as shown... Figure 17 As shown, Figure 17 (a), (b), and (c) are the light pattern diagrams for the eighth, ninth, and tenth regions, respectively, and the width of the second light pattern is equal along the second direction at all points.
[0093] As can be seen from the above, for the vehicle headlight module provided in this application, the size of the light-emitting surface of each second light source 211 in the second light source module 210 and the relative position between each second light source 211, as well as the size of multiple second inner lenses 221, can be used to adjust the second light pattern, so that the vehicle headlight module can output a high beam pattern that meets the design requirements, and can adjust the shape of the high beam pattern to achieve diversification of the low beam pattern, meet different application scenarios, and has strong practicality.

The emitting surfaces of the first light sources 1113, 1114, and 1115 are equal in size and larger than the emitting surface of the first light source 1111. The central axis of the emitting surface of the first light source 1111 forms a predetermined angle A with the first direction. The central axes of the emitting surfaces of the first light sources 1112, 1113, 1114, and 1115 are parallel to the first direction. The width of the first inner lens module 120 along the second direction is equal at all points, and the first inner lens 1211 and the first inner lens 1212 are equal in shape and size. The first inner lens 1214, the first inner lens 1213 and the first inner lens 1215 are equal in shape and size and are larger than the first inner lens 1211.
[0096] The second light source module 210 of the high beam module 200 includes five second light sources 211, which are labeled 2114, 2111, 2112, 2113, and 2115 along the second direction.
