The number of auxiliary high beam sub-sources 24-1 and auxiliary high beam sub-condensers 222-1 is adjusted according to requirements.

[0088] As a specific embodiment of the low beam condenser 221, referring to FIGS. 3-5, the upper side of the low beam condenser 221 is provided with an upper convex structure 223, which includes an upper convex structure reflecting surface 223-1 and an upper convex structure light exit surface 223-2. The upper convex structure 223 is configured such that the portion of the low beam light source 21 light rays that enter the low beam condenser 221 are upwardly directed to the upper convex structure light exit surface 223-2, reflected by the upper convex structure reflecting surface 223-1, and then exit through the upper convex structure light exit surface 223-2. The exiting light rays are transmitted to the second light exit element 23 and projected to the lower side boundary region of the high beam light pattern by the second light exit element 23. As shown in FIG. 6, the first low beam light exit beam 500 is the light exit beam formed by the light rays passing through the upper convex structure 223 provided on the upper side of the low beam condenser 221, and the second low beam light exit beam 600 is the light exit beam formed without the upper convex structure 223. By comparing the first low beam light exit beam 500 and the second low beam light exit beam 600, it can be seen that, by providing the upper convex structure 223 on the upper side of the low beam condenser 221, the upper side of the low beam condenser 221 has more effective light exit regions. The light rays are reflected by the upper convex structure reflecting surface 223-1 and exit from the upper convex structure light exit surface 223-2, which is vertically higher, and are forwardly directed to the second light exit element 23. Compared with the second low beam light exit beam 600, the first low beam light exit beam 500 forms a larger downwardly inclined angle and exits from the light exit surface of the second light exit element 23, thereby being able to be projected to a position further downwardly of the low beam light pattern and increasing the illumination range of the lower side boundary region of the low beam light pattern. As shown in FIG. 10, in the case where there is no upper convex structure 223, the lower side of the low beam light pattern formed by the corresponding embodiment is widened by 12.5°. As shown in FIG. 11, in the case where there is the upper convex structure 233, the lower side of the low beam light pattern formed by the embodiment is widened by 15.5°. The upper convex structure 10 increases the lower side of the low beam light pattern and increases the illumination range of the low beam light pattern, thereby shortening the dark area in front of the vehicle, facilitating the driver to see the obstacles in front of the vehicle, and improving the safety of driving.

[0089] As a specific embodiment of the low-beam condenser 221, as shown in FIGS. 3-5, the low-beam condenser 221 includes a plurality of low-beam sub-condensers 221-1 arranged laterally, and the upper side of at least part of the low-beam sub-condensers 221-1 is provided with an upper convex structure 223. As shown in FIG. 8, in this embodiment, the upper side of part of the low-beam sub-condensers 221-1 is provided with an upper convex structure 223 to avoid too many upper convex structures 223 resulting in insufficient brightness values of the final low-beam light pattern. As shown in FIGS. 3-5, the upper side of the low-beam sub-condenser 221-1 in the middle of the plurality of low-beam sub-condensers 221-1 is not provided with an upper convex structure 223, and the upper side of at least one low-beam sub-condenser 221-1 on both sides of the low-beam sub-condenser 221-1 in the middle is provided with an upper convex structure 223, which increases the lateral width of the low-beam light pattern while ensuring that the central region of the low-beam light pattern has sufficient brightness values. It should be noted that, under the premise of being able to meet the brightness values of the low-beam light pattern, an upper convex structure 223 can also be provided on the upper side of each low-beam sub-condenser 221-1.

[0090] The low-beam of the vehicle lamp is for close-range illumination. According to the standards related to vehicle lamps (for example, the Chinese standard GB25991), the low-beam light pattern has an important component called "III region" above the cutoff line, which mainly illuminates objects such as signs above the road surface, allowing the driver to obtain information about the signs. As a preferred embodiment of the low-beam condenser 221, referring to FIGS. 3-5 and 7, the lower side of the low-beam condenser 221 is provided with a low-beam lower convex structure 224, which includes a low-beam lower convex structure reflection surface 224-1 and a low-beam lower convex structure light exit surface 224-2. The low-beam lower convex structure 224 is configured such that part of the light from the low-beam light source 21 that enters the low-beam condenser 221 is directed downward to the low-beam lower convex structure reflection surface 224-1, is reflected by the low-beam lower convex structure reflection surface 224-1, and then exits through the low-beam lower convex structure light exit surface 224-2. The exiting light is transmitted to the second light exit element 23 and is projected upward by the second light exit element 23 to form a low-beam III region light pattern. By providing the low-beam lower convex structure 224 on the lower side of the low-beam condenser 221, the low-beam III region light pattern can be formed in cooperation with the low-beam light source 21 and the second light exit element 23 without the need to design a low-beam III region forming structure on the second light exit element 23 (such as a lens), thereby avoiding affecting the aesthetic appearance and optical performance of the second light exit element 23 (such as a lens).

[0091] It should be noted that, as shown in FIG. 3, the light exit surface of the auxiliary high beam condenser 222 can be a free-form surface, the light exit surfaces of the low beam condenser 221, the upper convex structure light exit surface 223-2 and the low beam lower convex structure light exit surface 224-2 can be provided with patterns, which include but are not limited to columnar patterns, polygonal patterns and arc patterns, and in some specific embodiments, the patterns are columnar patterns. By adjusting the shape and spacing of the columnar patterns in different regions, the degree of diffusion of light passing through these regions can be adjusted, achieving the purpose of adjusting the spread of the light patterns corresponding to these regions, while improving the uniformity of the light pattern.

[0092] As a specific embodiment of the low beam condenser 221, as shown in FIGS. 3 to 5, the low beam condenser 221 includes a plurality of low beam sub-condensers 221-1 arranged transversely, and the low beam sub-condensers 221-1 located at least on the two sides of the auxiliary high beam condenser 222 are provided with low beam lower convex structures 224 on the lower side, so that the low beam lower convex structures 224 can avoid the auxiliary high beam condenser 222 and avoid damaging the light exit surface of the auxiliary high beam condenser 222 by the low beam lower convex structures 224, thereby avoiding the decrease of the brightness value of the high beam center light pattern caused by the damage of the light exit surface of the auxiliary high beam condenser 222.

[0093] Specifically, referring to FIG. 7, the second light exit element 23 is a lens, and the low beam lower convex structure light exit surface 224-1 is configured such that the light rays emitted therefrom to the second light exit element 23 are transmitted along the lower side of the optical axis of the second light exit element 23, and then transmitted forwardly and upwardly to the upper side of the optical axis of the second light exit element 23 after refraction by the second light exit element 23; by adjusting the inclination of the low beam lower convex structure light exit surface 224-1, i.e., adjusting the inclination angle between the low beam lower convex structure light exit surface 224-1 and the optical axis of the second light exit element 23, the light rays emitted from the second light exit element 23 are projected to a position above the H-axis of the light distribution screen, forming a low beam III zone light pattern; in addition, the shape and / or spacing of the columnar patterns on the low beam lower convex structure light exit surface 224-1 can also be adjusted to adjust the shape, size and uniformity of the formed low beam III zone light pattern.

Further, referring to FIG. 3, a boundary line structure 225 is formed between the low beam condenser 221 and the auxiliary high beam condenser 222, the boundary line structure 225 is arranged corresponding to the cutoff line structure 25-1, that is, the shape of the boundary line structure 225 corresponds to the shape of the cutoff line structure 25-1, so that the light rays emitted by the low beam condenser 221 and the light rays emitted by the auxiliary high beam condenser 222 can be prevented from being projected to the corresponding light pattern area of the other party through the boundary line structure 225, effectively preventing the problem of mutual light leakage.

[0095] It should be noted that during the driving of the vehicle, the horizontal expansion of the basic low beam light pattern is limited in actual use, for example, during the turning of the vehicle, since the low beam light pattern is irradiated to the front of the vehicle, the area on the side of the turning of the vehicle cannot be effectively illuminated under the condition that the basic low beam light pattern is limited in horizontal expansion, thereby affecting the driving safety.

The second light-emitting part 122-4 is configured such that the light emitted by the second light-emitting part 122-4 is directed toward the light-incident surface of the first light-emitting element 13 located on the second side of the optical axis, and the third light-emitting part 122-6 is configured such that the light emitted by the third light-emitting part 122-6 is directed toward the light-incident surface of the first light-emitting element 13 located on the first side of the optical axis.

The third light-emitting part 122-6 emits light through the third light-emitting surface 122-61 to form a third accompanying light-emitting beam 300 located to the left of the first accompanying light-emitting beam 100. The third light-emitting surface 122-61 is a refractive surface, so that the third accompanying light-emitting beam 300 is directed towards the light-incident surface of the first light-emitting element 13 located to the right of the optical axis through refraction, forming a larger incident angle, so that the right side of the accompanying illuminated light pattern can be widened after being projected forward through the first light-emitting element 13.

[0107] Specifically, the second light-emitting surface 122-41 and the third light-emitting surface 122-61 are inclined to the optical axis of the first light-emitting element 13. By adjusting the angle between the optical axis of the second light-emitting surface 122-41 and the first light-emitting element 13, and the angle between the optical axis of the third light-emitting surface 122-61 and the first light-emitting element 13, the left and right width of the final illuminated light pattern can be controlled to meet the design requirements.

The first baffle reflective surface 15-1 is located on the first side of the optical axis of the first light-emitting element 13 along the transverse direction. The first baffle reflective surface 15-1 is configured to reflect the light emitted from the third light-emitting part 122-6 to the light-incident surface of the first light-emitting element 13, and then project it onto the second side of its optical axis through the first light-emitting element 13. The second baffle reflective surface 15-2 is located on the second side of the optical axis of the first light-emitting element 13 along the transverse direction. The second baffle reflective surface 15-2 is configured to reflect the light emitted from the second light-emitting part 122-4 to the light-incident surface of the first light-emitting element 13, and then project it onto the second side of its optical axis through the first light-emitting element 13. Specifically, referring to Figures 14, 27, and 28, the second accompanying light-emitting beam 200, emitted from the second light-emitting section 122-4 on the right, is directed towards the second baffle reflector 15-2 located to the left of the optical axis of the first light-emitting element 13. After being reflected by the second baffle reflector 15-2, it is directed forward and to the right towards the light-incident surface of the first light-emitting element 13, and then projected onto the right side of the optical axis of the first light-emitting element 13. The arrangement of the second baffle reflector 15-2 allows the second accompanying light-emitting beam 200 to have a longer light transmission path under the limited front-to-back space between the accompanying condenser 2 and the first light-emitting element 13, and it can enter the light-incident surface of the first light-emitting element 13 at a larger incident angle. After the light is projected forward by the first light-emitting element 13, the accompanying illumination light pattern has... The third accompanying light beam 300 emitted from the third light-emitting section 122-6 on the left is directed toward the first baffle reflector 15-1 located on the right side of the optical axis of the first light-emitting element 13. After being reflected by the first baffle reflector 15-1, it is directed forward and to the left toward the light-incident surface of the first light-emitting element 13, and then projected onto the left side of the optical axis of the first light-emitting element 13. The arrangement of the first baffle reflector 15-2 allows the third accompanying light beam 300 to have a longer light transmission path under the limitation of the front and rear space size between the accompanying condenser 2 and the first light-emitting element 13, and can enter the light-incident surface of the first light-emitting element 13 at a larger incident angle. After the light is projected forward by the first light-emitting element 13, the accompanying illumination light pattern has a greater left-side widening.

[0110] Preferably, referring to Figures 15, 20 to 25, the accompanying concentrator 122 further includes a fourth light-emitting section 122-7. The fourth light-emitting section 122-7 is disposed on one side of the first light-emitting section 122-2 along the vertical direction, which can be the upper side or the lower side. The first light-emitting section 122-2 also includes a third reflective surface 122-24. The third reflective surface 122-24 is configured to reflect part of the collimated beam vertically to the fourth light-emitting section 122-7, so that the reflected light is emitted forward through the fourth light-emitting section 122-7. This adds another light-emitting area to the vertical optical path of the accompanying concentrator 122 that forms the accompanying point-lit light pattern, increases the light emission angle of the light passing through the accompanying concentrator 122, and effectively expands the vertical width of the accompanying point-lit light pattern.

[0111] As a specific embodiment of the fourth light-emitting section, referring to Figures 15, 20, 23, and 24, the fourth light-emitting section 122-7 includes a fourth light-emitting surface 122-71 and a fourth light-emitting reflective surface 122-72 disposed opposite to each other. The reflected light from the third reflective surface 122-24 is transmitted downwards, and the fourth light-emitting reflective surface 122-72 is correspondingly disposed below the third reflective surface 122-24. The fourth light-emitting reflective surface 122-72 is configured to reflect the light reflected by the third reflective surface 122-24 to the fourth light-emitting surface 122-71, so that the reflected light from the fourth light-emitting reflective surface 122-72 is emitted forward through the fourth light-emitting surface 122-71.

[0112] It should be noted that the third reflecting surface 122-24 is disposed above the first light-emitting surface 122-21. That is, the light of the collimated beam located in the upper region is reflected downward by the third reflecting surface 122-24, and then reflected forward by the fourth light-emitting reflecting surface 122-72 to the fourth light-emitting surface 122-71. Finally, it is emitted forward through the fourth light-emitting surface 122-71 to form the fourth accompanying light-emitting beam 400. The fourth accompanying light-emitting beam 400 is located below the first accompanying light-emitting beam 100. The fourth accompanying light-emitting beam 400 is directed toward the light-incident surface of the first light-emitting element 13 located below the optical axis, so that it can be refracted by the first light-emitting element 13 and projected to the upper side of the optical axis, thereby effectively expanding the upper side of the accompanying illumination pattern.

[0113] Furthermore, in the embodiment of the high beam module 1 of this application that is provided with a baffle 15, referring to Figures 27 and 28, the baffle also includes a third baffle reflective surface 15-3. The third baffle reflective surface 15-3 is located on the lower side of the optical axis of the first light-emitting element 13, and the third baffle reflective surface 15-3 is configured to reflect the light emitted from the fourth light-emitting part 122-7 and the light emitted from the first light-emitting part 122-2 upward and forward to the light-incident surface of the first light-emitting element 13. This allows the first accompanying light-emitting beam 100 and the fourth accompanying light-emitting beam 400 to be incident forward and upward onto the light-incident surface of the first light-emitting element 13, and to have a large incident angle. This can further effectively expand the upper side of the accompanying illumination pattern. At the same time, after the first accompanying light-emitting beam 100 and the fourth accompanying light-emitting beam 400 are projected out by the first light-emitting element 13, the brightness of the upper edge of the accompanying illumination pattern can also be improved, thereby achieving a better appearance illumination effect. It should be noted that the aforementioned third baffle reflector 15-3 reflects at least the light rays of the first accompanying light beam 100 located on the lower side and the light rays of the fourth accompanying light beam 400 located on the lower side forward and upward toward the light incident surface of the first light emitting element 13.

[0114] It should be noted that, referring to Figures 14, 27, and 28, the first baffle reflective surface 15-1, the second baffle reflective surface 15-2, and the third baffle reflective surface 15-3 form a semi-enclosed structure. This structure further expands the vertical and horizontal width of the accompanying illumination pattern while also reflecting and utilizing light rays directed to the left, right, and lower sides. This improves the utilization rate of the light emitted through the accompanying concentrator 122, effectively avoids stray light generation, improves the light pattern quality of the accompanying illumination pattern, and enhances the aesthetics of the high beam module 1's illumination effect. The baffle 15 and the first light-emitting element 13 are fixedly mounted on the vehicle via the lens bracket 8.

[0115] [Correction 06.03.2025 according to Rule 91] As a specific embodiment of the first light-emitting surface 122-21, referring to Figure 21, the first light-emitting surface 122-21 is a concave curved surface formed by stretching a concave curve along the extension direction of the sweep line. The sweep line is a straight line or arc extending vertically, so that the first accompanying light-emitting beam 100 emitted through the first light-emitting surface 122-21 diffuses in the lateral (left-right direction); as another specific embodiment of the first light-emitting surface 122-21, the first light-emitting surface 122-21 can also be a plane.

[0116] [Correction 06.03.2025 based on Rule 91] As a specific embodiment of the first light-transmitting part 122-3, referring to Figures 21, 22 and 32, the first light-transmitting part 122-3 includes a first front sidewall 122-31 and a first rear sidewall 122-32. Both the first front sidewall 122-31 and the first rear sidewall 122-32 are total reflection surfaces. After the light reflected by the first reflection surface 122-22 enters the first light-transmitting part 122-3, the light can be reflected back and forth between the first front sidewall 122-31 and the first rear sidewall 122-32, and finally guided to the second light-emitting reflection surface 122-42, effectively improving the utilization rate of light.

[0117] As a specific embodiment of the second light-transmitting part 122-5, referring to Figures 21, 22 and 32, the second light-transmitting part 122-5 includes a second front sidewall 122-51 and a second rear sidewall 122-52. Both the second front sidewall 122-51 and the second rear sidewall 122-52 are total reflection surfaces. After the light reflected by the second reflection surface 122-23 enters the second light-transmitting part 122-5, the light can be reflected back and forth between the second front sidewall 122-51 and the second rear sidewall 122-52, and finally guided to the third light-emitting reflection surface 122-62, effectively improving the utilization rate of light.

[0118] It should be noted that there are two specific implementations of the above-mentioned total internal reflection mask. The first specific implementation is to coat the optical surface with a reflective coating to form a total internal reflection surface. The second specific implementation is to utilize the principle of total internal reflection, that is, when light enters a medium with a lower refractive index from a medium with a higher refractive index, if the angle of incidence is greater than a certain critical angle (the light is away from the normal), the refracted light will disappear, and all the incident light will be reflected and will not enter the medium with a lower refractive index. This can be achieved by reasonably setting the angle of incidence of the received light on the optical surface, so that the optical surface forms a total internal reflection surface.

[0119] In a preferred embodiment, referring to Figures 14 to 17, a high beam concentrator 121 is provided with a high beam downward convex structure 123 on its lower side. The high beam downward convex structure 123 includes a high beam downward convex structure reflective surface 123-1 and a high beam downward convex structure light-emitting surface 123-2. The high beam downward convex structure 123 is configured such that part of the light from the high beam source 11 entering the high beam concentrator 121 is directed downward toward the high beam downward convex structure reflective surface 123-1, reflected by the high beam downward convex structure reflective surface 123-1, and then emitted through the high beam downward convex structure light-emitting surface 123-2. The emitted light is transmitted to the first light-emitting element 13 and projected upward toward the upper boundary region of the high beam pattern through the first light-emitting element 13, thereby expanding the illumination range of the upper boundary region of the high beam pattern. As shown in Figure 17, the dashed line represents the reflective surface structure of the high beam concentrator 121 without the high beam downward convex structure 123. This application provides a high beam downward convex structure 123 on the lower side of the high beam concentrator 121, so that the lower side of the high beam concentrator 121 has a larger effective light-emitting area. After the light is reflected by the high beam downward convex structure 123-1, it is emitted from the high beam downward convex structure 123-2 at a lower position in the vertical direction and shines forward toward the first light-emitting element 13. As shown in Figure 17, the first high-beam output beam 800 is the output beam formed by light passing through the high-beam concentrator 121 with a high-beam downward convex structure 123 disposed on the lower side, and the second high-beam output beam 900 is the output beam formed without the high-beam downward convex structure 123 disposed on the lower side. By comparing the first high-beam output beam 800 and the second high-beam output beam 900, it can be seen that this application, by providing the high-beam concentrator 121 with a high-beam downward convex structure 123 on the lower side, enables the lower side of the high-beam concentrator 121 to have more... In the effective light-emitting area, after the light is reflected by the reflective surface 123-1 of the high beam downward convex structure, it is emitted from the light-emitting surface 123-2 of the high beam downward convex structure with a lower vertical height and shines forward toward the first light-emitting element 13. Compared with the second high beam emitting beam 900, the lower first high beam emitting beam 800, together with the first light-emitting element 13 (preferably a lens), forms a larger upward refraction angle, which can then be projected to a higher position of the high beam pattern, increasing the illumination range of the upper boundary area of ​​the high beam pattern.

[0120] As shown in Figure 18, when the high beam concentrator 121 does not have the high beam downward convex structure 123, the upper light emission angle of the high beam pattern projected onto the light distribution screen is 5°. When applied to actual road lighting, the brightness value of the road sign illuminating 50m ahead is 0.05lx. As shown in Figure 19, when the high beam concentrator 121 has the high beam downward convex structure 123, the upper light emission angle of the high beam pattern projected onto the light distribution screen increases to 7°. When applied to actual road lighting, the brightness value of the road sign illuminating 50m ahead increases from 0.05lx to 1.85lx, thereby improving the driver's visibility under high beam lighting and significantly improving driving safety at high speeds.

[0121] As a specific embodiment of the high beam concentrator 121, as shown in Figures 15 and 16, the high beam concentrator 121 includes a plurality of horizontally arranged high beam sub-concentrators 121-1, and at least some of the high beam sub-concentrators 121-1 have a high beam downward protrusion structure 123 on their lower side. As shown in Figure 16, in this embodiment, some of the high beam sub-concentrators 121-1 have a high beam downward protrusion structure 123 on their lower side to avoid insufficient brightness value of the final high beam pattern due to too many high beam downward protrusion structures 123. For example, the high beam sub-concentrator 121-1 located in the middle does not have a high beam downward protrusion structure 123 on its lower side, while at least one high beam sub-concentrator 121-1 on both sides of the high beam sub-concentrator 121-1 located in the middle has a high beam downward protrusion structure 123 on its lower side. This increases the upper side widening of the high beam pattern while ensuring that the maximum illuminance of the high beam pattern meets regulatory requirements. It should be noted that, provided that the brightness value of the high beam pattern can be met, a high beam convex structure 123 can also be set on the lower side of each high beam concentrator 121-1.

[0122] As a specific embodiment of the high beam downward convex structure 123, referring to Figure 17, the light-emitting surface 123-2 of the high beam downward convex structure is configured such that the light rays emitted from the light-emitting surface 123-2 after being reflected by the reflective surface 123-1 of the high beam downward convex structure are transmitted along the lower side of the optical axis of the first light-emitting element 13 and are incident on the light-incident surface of the first light-emitting element 13. After being emitted from the first light-emitting element 13, they are projected onto the upper side of the optical axis of the first light-emitting element 13, thereby reaching the upper boundary region of the high beam pattern. Further, the projection angle formed by the light-emitting surface 123-2 of the high beam downward convex structure and the optical axis of the first light-emitting element 13 in the vertical cross-section is greater than or equal to 63° and less than or equal to 73°, so that the light rays emitted from the light-emitting surface 123-2 of the high beam downward convex structure can reach the first light-emitting element 13 and be refracted by the first light-emitting element 13 and projected onto the upper boundary region of the high beam pattern. The aforementioned vertical cross-section is parallel to the front-back direction and the up-down direction.

[0123] As a specific embodiment of the high beam convex structure light-emitting surface 123-2, as shown in Figure 15, the high beam convex structure light-emitting surface 123-2 is provided with columnar patterns extending vertically. By adjusting the shape and / or spacing of the columnar patterns in different areas, the degree of light diffusion when passing through these areas can be adjusted, thereby achieving the purpose of adjusting the corresponding light pattern broadening in these areas and improving the uniformity of the light pattern.

[0124] As one specific embodiment of the convex reflective surface 123-1 for high beams, the convex reflective surface 123-1 for high beams is an elliptical surface, a near-elliptical surface, a parabolic surface, or a near-parabolic surface. A near-elliptical surface refers to a curved surface whose shape and light effect are similar to an elliptical surface, and a near-parabolic surface refers to a curved surface whose shape and light effect are similar to a parabolic surface. These curved surfaces all have the function of converging light, which can adjust the angle of the light projected onto the upper boundary area of ​​the high beam pattern.

[0125] In some specific embodiments, referring to Figures 14 to 16, the high beam concentrator 121 and the accompanying concentrator 122 are integrally molded parts, which facilitates manufacturing and assembly. The high beam concentrator 121 and the accompanying concentrator 122 can be formed into an integral part by injection molding, for example, they can be integrally injection molded using PMMA (polymethyl methacrylate) material.

[0126] In some specific embodiments, the high beam module 1 also includes a first circuit board 16, on which the high beam light source 11 and the accompanying light source 14 are jointly disposed, thereby improving the integration of components and facilitating assembly. Furthermore, the first circuit board 16 is mounted on the first heat sink 18 by mounting screws, which facilitates the arrangement of heat dissipation space.

[0127] To better understand the technical solution of this application, the following description is based on the preferred technical features of the vehicle lighting assembly of this application.

[0128] Referring to Figures 1 to 5, 14 to 16, 20 to 24, and 27 to 28, the vehicle headlight assembly of this application includes a high beam module 1 and a low beam module 2. The low beam module 2 includes a low beam light source 21, an auxiliary high beam light source 24, a corner light source 26, a second primary optical element 22, and a second light-emitting element 23. The second primary optical element 22 includes a low beam concentrator 221 and an auxiliary high beam concentrator 222 arranged vertically. The low beam concentrator 221 is correspondingly arranged with the low beam light source 21 so that the light emitted from the low beam light source 21 is focused by the low beam concentrator 221 and then emitted by the second light-emitting element 23 to form a low beam pattern, thereby realizing the basic low beam lighting function. The auxiliary high beam concentrator 222 is correspondingly arranged with the auxiliary high beam light source 24 so that the light emitted from the auxiliary high beam light source 24 is focused by the auxiliary high beam light source 24. After the light is focused by the auxiliary high beam concentrator 222, it is emitted by the second light-emitting element 23 and projected onto the central area of ​​the high beam pattern to form the high beam center beam pattern, thereby further enhancing the brightness of the central area of ​​the high beam pattern. Corner lamp concentrators 226 are integrally formed on the left and right sides of the low beam concentrator 221. Corner lamp concentrators 226 are correspondingly provided with corner lamp light sources 26. The light emitted from the corner lamp light sources 26 is focused by the corner lamp concentrators 226, and then emitted by the second light-emitting element 23 and projected onto the horizontal side area of ​​the low beam pattern. By lighting up the corner lamp light sources 26, the width of the low beam pattern can be increased. Therefore, the low beam module 2 of this application can achieve different lighting effects by individually controlling the lighting of the low beam light source 21, the auxiliary high beam light source 24, and the corner lamp light sources 26 according to different lighting needs. Specifically, when only the low beam light source 21 is lit, the low beam pattern formed by the left headlight is shown in Figure 33, and the low beam pattern formed by the right headlight is shown in Figure 34; when both the low beam light source 21 and the auxiliary high beam light source 24 are lit, the low beam pattern and high beam center beam pattern formed by the left headlight are shown in Figure 39, and the low beam pattern and high beam center beam pattern formed by the right headlight are shown in Figure 40; when both the low beam light source 21 and the cornering light source 26 are lit, the low beam pattern and cornering light pattern formed by the left headlight are shown in Figure 41, and the low beam pattern and cornering light pattern formed by the right headlight are shown in Figure 42.

[0129] The high beam module 1 of this application includes a high beam light source 11, a companion light source 14, a first primary optical element 12, and a first light-emitting element 13. The first primary optical element 12 includes a high beam concentrator 121 and a companion concentrator 122, with the companion concentrator 122 positioned below the high beam concentrator 121. The first light-emitting element 13 is a lens. The light emitted from the high beam light source 11 is suitable for being focused by the high beam concentrator 121 and then projected by the first light-emitting element 13 to form a high beam pattern. The companion concentrator 121 is a solid, integrally formed light conductor, including a concentrating section 122-1, a first light-emitting section 122-2, a first light-transmitting section 122-3, and a second light-emitting section 122. -4. The second light-transmitting section 122-5, the third light-emitting section 122-6, and the fourth light-emitting section 122-7, together with the light emitted by the light source 122, are converged by the light-collecting section 122-1 to form a collimated beam that propagates forward. The first light-emitting section 122-2 is located in front of the light-collecting section 122-1. The first light-emitting section 122-2 includes a first light-emitting surface 122-21, a first reflective surface 122-22, a second reflective surface 122-23, and a third reflective surface 122-24. The second reflective surface 122-23 and the first reflective surface 122-22 are located on the left and right sides of the first light-emitting surface 122-21, respectively. The third reflective surface 122-24 is located on the first light-emitting surface 122-21. On the upper side of the light surface 122-21, the collimated beam located in the middle region is directly emitted forward through the first light-emitting surface 122-21 to form the first accompanying light-emitting beam 100. The right side of the first light-emitting part 122-2 is sequentially connected to the first light-transmitting part 122-3 and the second light-emitting part 122-4. The second light-emitting part 122-4 includes a second light-emitting surface 122-41 and a second light-emitting reflective surface 122-42 arranged opposite to each other. The collimated beam located in the right-side region is reflected to the right by the first reflective surface 122-22, then guided by the first light-transmitting part 122-3 to the second light-emitting reflective surface 122-42, and then reflected again by the second light-emitting reflective surface 122-42 to… The second light-emitting surface 122-41 emits light forward to form a second accompanying light-emitting beam 200; the left side of the first light-emitting part 122-2 is connected to the second light-transmitting part 122-5 and the third light-emitting part 122-6 in sequence. The third light-emitting part 122-6 includes a third light-emitting surface 122-61 and a third light-emitting reflective surface 122-62 arranged opposite to each other. The light rays of the collimated beam located in the left region are reflected to the left by the second reflective surface 122-23, and then guided to the third light-emitting reflective surface 122-62 by the second light-transmitting part 122-5. Then, they are reflected by the third light-emitting reflective surface 122-62 to the third light-emitting surface 122-61 and emitted forward to form a third accompanying light-emitting beam 300.The fourth light-emitting section 122-7 is located below the first light-emitting section 122-2. The fourth light-emitting section 122-7 includes a fourth light-emitting surface 122-71 and a fourth light-emitting reflective surface 122-72 arranged opposite to each other. The light rays of the collimated beam located in the upper region are reflected downward by the third reflective surface 122-24, and then reflected forward by the fourth light-emitting reflective surface 122-72 to the fourth light-emitting surface 122-71. Finally, the light rays are emitted forward through the fourth light-emitting surface 122-71 to form the fourth accompanying light-emitting beam 400. This technical solution allows for the realization of three light-emitting regions in the left and right directions by simply setting one accompanying light source 122 corresponding to the focusing part 122-1 of the accompanying condenser 121: a first accompanying light-emitting beam 100, a second accompanying light-emitting beam 200, and a third accompanying light-emitting beam 300. Referring to Figure 25, the first accompanying light-emitting beam 100 is directly projected forward through the first light-emitting element 13, while the second accompanying light-emitting beam 200 is projected forward and to the left onto the light-incident surface of the first light-emitting element 13, thus projecting onto the left side of the accompanying illuminated light pattern and widening the left side of the accompanying illuminated light pattern. The third accompanying light-emitting beam 300 is projected forward and to the right onto the first... The light-emitting surface of the first light-emitting element 13 is projected onto the right side of the accompanying illuminated light pattern, thus expanding the right-side light-emitting angle of the accompanying illuminated light pattern. The fourth accompanying light-emitting beam 300 is projected forward toward the light-emitting surface of the first light-emitting element 13 located below the optical axis, and thus, after being refracted by the first light-emitting element 13, is projected forward and upward toward the upper side of the accompanying illuminated light pattern, expanding and widening the upper side of the accompanying illuminated light pattern. See Figure 26 for details. The final accompanying illuminated light pattern has a left-right angle of 35°, an upper angle of 25°, and a lower angle of 2.5°, thus forming a large light-emitting angle accompanying illumination effect, and the four light-emitting areas formed improve the uniformity of the light pattern.

[0130] In the preferred embodiment described above, referring to Figure 27, a baffle 15 can be provided between the accompanying concentrator 121 and the first light-emitting element 13. The baffle 15 includes a first baffle reflective surface 15-1, a second baffle reflective surface 15-2, and a third baffle reflective surface 15-3. The first baffle reflective surface 15-1 and the second baffle reflective surface 15-2 are located on the right and left sides of the optical axis of the first light-emitting element 13, respectively. The third baffle reflective surface 15-3 is located below the optical axis of the first light-emitting element 13. The second accompanying light-emitting beam 200 is directed towards the second baffle reflective surface 15-2, and after being reflected by the second baffle reflective surface 15-2, it is directed forward and to the right towards the light-incident surface of the first light-emitting element 13. Then, it is projected by the first light-emitting element 13 to the right side of the accompanying illuminated light pattern, which allows it to enter the light-incident surface of the first light-emitting element 13 at a larger incident angle, further extending the right-side light-emitting angle of the accompanying illuminated light pattern. The third accompanying light-emitting beam 300 is directed towards the first baffle reflective surface 15-1, and after being reflected by the second baffle reflective surface 15-2, it is directed forward and to the right towards the light-incident surface of the first light-emitting element 13. After being reflected by the first baffle reflector 15-1, the light beam is directed forward and to the left towards the incident surface of the first light-emitting element 13, and then projected by the first light-emitting element 13 onto the left side of the accompanying illuminated light pattern. This allows the light to enter the incident surface of the first light-emitting element 13 at a larger incident angle, further widening the left side of the accompanying illuminated light pattern. The first accompanying light-emitting beam 100 and the fourth accompanying light-emitting beam 400 are directed towards the third baffle reflector 15-1, and after being reflected by the third baffle reflector 15-3, they are directed forward and upward towards the incident surface of the first light-emitting element 13, and then projected by the first light-emitting element 13 onto the upper side of the accompanying illuminated light pattern. This allows the light to enter the incident surface of the first light-emitting element 13 at a larger incident angle, further widening the upper side of the accompanying illuminated light pattern. See Figure 29 for details. The final accompanying illuminated light pattern has a left-right angle of 45°, an upper angle of 40°, and a lower angle of 2.5°, thus forming a large-angle accompanying illumination effect and more uniform light emission. Therefore, different lighting effects can be achieved by individually controlling the on / off state of the high beam source 11 and the accompanying light source 14. Specifically, when only the accompanying light source 14 is lit, the high beam accompanying light pattern formed by the left headlight is shown in Figure 35, and the high beam accompanying light pattern formed by the right headlight is shown in Figure 36; when only the high beam source 11 is lit, the high beam light pattern formed by the left headlight is shown in Figure 37, and the high beam light pattern formed by the right headlight is shown in Figure 38.

[0131] Through the above preferred embodiments, the vehicle lighting assembly of this application is actually used in a vehicle, and the low beam module 2 and high beam module 1 have multiple lighting logics, specifically:

[0132] First headlight mode: When the vehicle receives a low beam signal, the low beam light source 21 of the corresponding low beam module 2 of the left and right headlights is lit, and the accompanying light source 14 of the corresponding high beam module 1 of the left and right headlights is lit at the same time. The road surface pattern formed by the left and right headlights is shown in Figure 43, thereby realizing the lighting of the basic low beam pattern and the accompanying lighting of the appearance of the high beam module 2, improving the aesthetics.

[0133] Second headlight mode: When the vehicle inputs high beam signal 1, the low beam light source 21 of the corresponding low beam module 2 of the left and right headlights is lit, and the high beam light source 11 of the corresponding high beam module 1 of the left and right headlights is lit at the same time. The road surface pattern formed by the left and right headlights together is shown in Figure 44, thereby realizing the lighting of the basic low beam pattern and the basic high beam pattern, and realizing the high beam lighting needs.

[0134] Third headlight mode: When the vehicle inputs high beam signal 2, the low beam light source 21 and auxiliary high beam light source 24 of the corresponding low beam module 2 of the left and right headlights are lit, and the high beam light source 11 of the corresponding high beam module 1 of the left and right headlights is lit at the same time. The road surface pattern formed by the left and right headlights together is shown in Figure 45, thereby realizing the lighting of the basic low beam pattern and the basic high beam pattern. On the basis of the second headlight mode, the brightness of the central area of ​​the high beam pattern is further improved, so that the high beam illumination distance is longer and the area in front of the vehicle is brighter, giving the driver a better driving experience and safety in special situations.

[0135] Fourth headlight mode: When the vehicle inputs low beam and cornering light signals, the low beam light source 21 and cornering light source 26 of the corresponding low beam module 2 of the left and right headlights are illuminated. At the same time, the accompanying light source 14 of the corresponding high beam module 1 of the left and right headlights is illuminated. The road surface pattern formed by the left and right headlights together is shown in Figure 46. This realizes the illumination of the basic low beam pattern and effectively increases the width of the low beam pattern on the basis of the first headlight mode, so that the driver has a better driving experience and safety in special situations. For example, when the vehicle turns at night, the driver can more easily observe the road conditions on the turning side. It also realizes the accompanying illumination of the appearance of the high beam module 2, improving the aesthetics.

[0136] Through the preferred embodiments described above, the vehicle lighting assembly of this application integrates low beam, cornering light, and high beam SPOT (increasing the center brightness of the high beam pattern) functions in the low beam module 2 without adding additional auxiliary modules, and integrates high beam and low beam simultaneous illumination functions in the high beam module 1. By integrating multiple functions within the same module, the optical utilization rate of the lenses (first light-emitting element 13 and second light-emitting element 23) is increased, optical performance is improved while controlling costs, and the addition of the high beam SPOT function to the low beam module provides an additional brightness option for the high beam. When the vehicle is traveling at high speed and requires higher road surface brightness, activating the high beam SPOT function of the low beam module can provide the driver with a better driving experience and safety.
