[0002] In recent years, with the development trend of vehicle intelligence and the continuous improvement of regulatory requirements, many corresponding adjustments and improvements have been made in the field of vehicle lamps.

[0003] In the prior art solutions, in order to meet the luminous flux requirements, multiple LEDs are placed in a single unit cavity. However, the aggregation of multiple LEDs causes the temperature of this unit to be relatively high during operation, with a greater thermal risk. Moreover, the excessive aggregation of multiple LEDs results in an insufficient light dispersion angle, failing to meet the requirements of light pattern broadening, and a relatively high cost.

[0004] Therefore, it is necessary to design a new type of dual-light module to overcome or alleviate the above technical problems. Summary of the Invention

[0057] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The detailed description and drawings of the following examples are used to exemplarily illustrate the principle of the present invention, but cannot be used to limit the scope of the present invention. The present invention can be implemented in many different forms, not limited to the specific embodiments disclosed in the text, but including all technical solutions falling within the scope of the claims.

[0059] It should be noted that for the convenience of describing the present invention and simplifying the description, generally, the installation orientation of the dual-light module is substantially the same as that when the vehicle lamp is actually used on the vehicle. For example, the lens is in the front, and correspondingly, the primary optical element is in the rear. The horizontal arrangement of each unit optical system means that each unit optical system is arranged substantially along the left-right direction, and the vertical direction means substantially along the up-down direction. In the description of the present invention, the indicated orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0060] In addition, words such as "including" or "comprising" used in the present invention mean that the elements before this word are covered by the elements listed after this word, and do not exclude the possibility of also covering other elements.

[0061] It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. When it is described that a specific device is located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device.

[0062] All terms used in the present invention have the same meanings as those understood by those of ordinary skill in the art to which the present invention pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be construed to have meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0063] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0064] Such as Figures 1 to 3 、 Figures 14 to 16As shown in the figure, an embodiment of the present invention provides a dual-light module for implementing a low-beam function and a high-beam function. The dual-light module includes a lens and a plurality of unit optical systems. The unit optical system includes a primary optical element and a light source. Each unit optical system is arranged in sequence along the transverse direction. The lens has a plurality of sequentially connected lens units, and each unit optical system is correspondingly arranged with each lens unit. And at least one of each unit optical system is a low-high beam combined unit system. The low-high beam combined unit system includes a low-beam primary optical element 3 and a high-beam primary optical element 5, a low-beam light source 2 and a high-beam light source 4. The low-high beam combined unit system corresponds to a low-high beam combined lens unit 1. The low-beam primary optical element 3 is configured to collimate the light emitted by the low-beam light source 2 towards the low-high beam combined lens unit 1 and project it through the low-high beam combined lens unit 1 to form an image. The high-beam primary optical element 5 is configured to collimate the light emitted by the high-beam light source 4 towards the low-high beam combined lens unit 1 and project it through the low-high beam combined lens unit 1 to form an image.

[0065] Based on the above technical solution, in the dual-light module of the present invention, a plurality of unit optical systems are arranged in sequence along the transverse direction. Each unit optical system is independent and correspondingly arranged with different lens units, respectively used to implement different functions. The light sources are more dispersed, which can improve the thermal risk of the system. Moreover, in each unit optical system, at least one is a low-high beam combined unit system. The low-high beam combined unit system has a low-beam light source 2, a low-beam primary optical element 3, a high-beam light source 4, and a high-beam primary optical element 5. The light emitted by the low-beam light source 2 is used to form a low-beam light pattern after passing through the low-beam primary optical element 3 and the low-high beam combined lens unit 1. The light emitted by the high-beam light source 4 is used to form a high-beam light pattern after passing through the high-beam primary optical element 5 and the low-high beam combined lens unit 1. The low beam and the high beam share the low-high beam combined lens unit 1. Without affecting the high beam, a low-beam light source 2 and a low-beam primary optical element 3 are additionally arranged in the high-beam unit system, so that the high-beam unit system is transformed into a low-high beam combined unit system. This design can increase the broadening of the low-beam light pattern. And because no additional low-beam light source 2 and low-beam primary optical element 3 are arranged in other low-beam unit systems, the arrangement of the low-beam light source 2 will not be too concentrated to cause thermal risk. Therefore, compared with the prior art that requires an additional low-beam module to increase the broadening of the low-beam light pattern, the technical solution of the present invention is simple and reliable, and the cost is relatively low.

[0066] It should be noted that according to different functions to be realized, each lens unit can be divided into a low-high beam combined lens unit 1, a low-beam lens unit 6, and a high-beam lens unit 7.

[0067] In a traditional high-low beam lighting module, in the low beam mode, the lens area corresponding to the high beam module is not lit, resulting in a poor appearance of the vehicle lamp when lit. To achieve a good appearance of the vehicle lamp when lit, it is necessary to actively light the lens area corresponding to the high beam module to achieve the effect of high beam accompanying lighting in the low beam mode. This method not only causes a certain amount of energy waste but also requires additional components to achieve the accompanying lighting effect, increasing the cost. For example, in the dual-light module of the present invention, some unit optical systems can be selected as the low beam unit system, and the remaining unit optical systems can be used as the high-low beam combined unit system. For the high-low beam combined unit system, its low beam mode (the low beam light source 2 and the low beam primary optical element 3 are used to form the low beam light pattern) and high beam mode (the high beam light source 4 and the high beam primary optical element 5 are used to form the high beam light pattern) share the high-low beam combined lens unit 1. In the low beam mode, the corresponding lens unit and the high-low beam combined lens unit 1 can be lit together, and there is no need to add additional components to achieve the high beam accompanying lighting effect in the low beam mode, thus obtaining a good appearance of the vehicle lamp when lit.

[0068] Specifically, Figures 14 to 16 An embodiment of the dual-light module is provided. Two low beam unit systems are arranged in the middle position, and a high-low beam combined unit system is arranged on each of the left and right sides of the two low beam unit systems. The low beam unit system includes at least one low beam light source 2 and at least one low beam primary optical element 3. The low beam unit system corresponds to a low beam lens unit 6. Each low beam primary optical element 3 is configured to collimate the light emitted by the corresponding low beam light source 2 towards the low beam lens unit 6 and form an image through the low beam lens unit 6. In the case of the low beam mode, the low beam light source 2 in the low beam unit system is lit. At the same time, the low beam light source 2 in the high-low beam combined unit system is also lit. The low beam light source 2 in the high-low beam combined unit system makes the divergence angle of the low beam light large enough to be used to increase the broadening of the low beam light pattern. Moreover, since the low beam light source 2 in the high-low beam combined unit system is not arranged in the low beam unit system, the low beam light source 2 is arranged more dispersedly, which can improve the thermal risk of the system and at the same time improve the low beam optical efficiency.

[0069] It should be noted that for the low beam unit system, the number of the low beam light source 2 and the low beam primary optical element 3 arranged therein can be selected according to design requirements. Moreover, the number of the low beam unit system and the high-low beam combined unit system can be selected according to design requirements. The positional relationship between the low beam unit system and the high-low beam combined unit system can also be arranged according to design requirements. For example, the low beam unit system can be arranged in the middle position, and the high-low beam combined unit system can be arranged outside the low beam unit system, or the high-low beam combined unit system can be arranged in the middle position, and the low beam unit system can be arranged outside the high-low beam combined unit system, or the low beam unit system and the high-low beam combined unit system can be arranged in other orders.

[0070] In some embodiments, a high beam unit system, a low beam unit system, and a high-low beam combined unit system can also be arranged in the dual-beam module. Some of the unit optical systems are selected as the high beam unit system, some of the unit optical systems are selected as the low beam unit system, and the remaining unit optical systems are selected as the high-low beam combined unit system. Figures 1 to 3 Another embodiment of the dual-beam module is provided, in which three low beam unit systems are arranged in the middle position, three high beam unit systems are arranged on the left side, and one high-low beam combined unit system is arranged on the right side. Specifically, the high beam unit system includes at least one high beam light source 4 and at least one high beam primary optical element 5. The high beam unit system corresponds to a high beam lens unit 7. Each high beam primary optical element 5 is configured to collimate the light emitted by the corresponding high beam light source 4 towards the high beam lens unit 7 and form an image through the high beam lens unit 7. In the case of the high beam mode, the high beam light source 4 in the high beam unit system is lit. At the same time, the high beam light source 4 in the high-low beam combined unit system is also lit, so that the divergence angle of the high beam light is large enough to be used to increase the broadening of the high beam light pattern. Moreover, since the high beam light source 4 in the high-low beam combined unit system is not arranged in the high beam unit system, the high beam light sources 4 are arranged more dispersedly, which can improve the thermal risk of the system and at the same time improve the high beam optical efficiency.

[0071] It should be noted that for the high beam unit system, the number of the high beam light sources 4 and the high beam primary optical elements 5 arranged therein can be selected according to the design requirements. Moreover, the number of the high beam unit system, the low beam unit system, and the high-low beam combined unit system can be selected according to the design requirements. The positional relationship between the high beam unit system, the low beam unit system, and the high-low beam combined unit system can also be arranged according to the design requirements. For example, the low beam unit system can be arranged in the middle position, the high beam unit system can be arranged on the left side, and the high-low beam combined unit system can be arranged on the right side; or, the high-low beam combined unit system can be arranged in the middle position, the low beam unit system can be arranged on the right side of the high-low beam combined unit system, and the high beam unit system can be arranged on the left side of the high-low beam combined unit system; or, the high beam unit system can be arranged in the middle position, the high-low beam combined unit system can be arranged on the right side, and the low beam unit system can be arranged on the left side; or, the high beam unit system, the low beam unit system, and the high-low beam combined unit system are arranged in other orders.

[0072] In addition, in addition to adopting the above combination method of the low beam unit system and the high-low beam combined unit system or adopting the above combination method of the high beam unit system, the low beam unit system, and the high-low beam combined unit system, the dual-beam module can also adopt a combination method such as a plurality of high-low beam combined unit systems or a combination method of the high beam unit system and the high-low beam combined unit system. These combination methods can all achieve the technical effects of the dual-beam module.

[0073] In some embodiments, for the high and low beam combination unit system, the positional relationship between the high beam light source 4 and the low beam light source 2 can also be arranged according to design requirements. For example, in the high and low beam combination unit system, the distance between the low beam light source 2 and the optical axis 11 of the high and low beam combination lens unit 1 is greater than the distance between the high beam light source 4 and the optical axis 11 of the high and low beam combination lens unit 1. Figure 9 An embodiment is shown in which the distance between the low beam light source 2 and the optical axis 11 of the high and low beam combination lens unit 1 is greater than the distance between the high beam light source 4 and the optical axis 11 of the high and low beam combination lens unit 1. In Figure 9 looking down from above the high and low beam combination unit system, the high beam light source 4 and the high beam primary optical element 5 are generally located on the optical axis 11 of the high and low beam combination lens unit 1 or close to the optical axis 11 of the high and low beam combination lens unit 1. That is to say, as Figure 12 and Figure 13 shown, the distance between the high beam light source 4 and the optical axis 11 of the high and low beam combination lens unit 1 is less than or equal to 2 mm. In addition, the high beam light source 4 is arranged at or near the focal point of the high and low beam combination lens unit 1. Preferably, the distance between the high beam light source 4 and the focal point of the high and low beam combination lens unit 1 is less than or equal to 2 mm. The light emitted by the high beam light source 4 is collimated by the high beam primary optical element 5 and then projected through the high and low beam combination lens unit 1 to form a light spot. The high and low beam combination lens unit 1 forms an inverted image of the high beam light source 4 located on the focal plane of the high and low beam combination lens unit 1. The light rays emit from the focal point and are parallel to the optical axis 11 after passing through the high and low beam combination lens unit 1; the light rays emit from a place far from the focal point and form an angle with the optical axis 11 after passing through the high and low beam combination lens unit 1. The farther the high beam light source 4 is from the focal point, the larger the angle. Thus, in Figure 9 the embodiment of, as Figure 10 shown, the central bright spot of the high beam light pattern projected through the high and low beam combination lens unit 1 is located near the HV intersection position on the photometric screen, that is, the high beam light rays are more concentrated near the HV intersection. Relative to the high beam light source 4 and the high beam primary optical element 5, the low beam light source 2 and the low beam primary optical element 3 are located at a position farther from the optical axis 11 of the high and low beam combination lens unit 1. Thus, in Figure 9 the embodiment of, as Figure 11 shown, the central bright spot of the low beam light pattern projected after passing through the high and low beam combination lens unit 1 will be at a position farther from the HV intersection.

[0074] It should be noted that Figure 10 and Figure 11 the light patterns shown refer to the projection shapes of the light rays of the vehicle lamp on the photometric screen 25 m in front of the vehicle. The area on the photometric screen is usually divided by the horizontal line H and the vertical line V. As Figure 9As shown, the high beam light source 4 and the high beam primary optical element 5 are located on the optical axis 11 of the high and low beam combined lens unit 1 or at a position close to the optical axis 11 of the high and low beam combined lens unit 1, such as Figure 10 As shown, the central bright spot of the high beam light pattern projected after passing through the high and low beam combined lens unit 1 is located near the HV intersection position on the photometric screen, which can increase the illuminance in the HV intersection area and improve the irradiation distance of the high beam. Correspondingly, as Figure 9 As shown, the low beam light source 2 and the low beam primary optical element 3 are located at a position farther from the optical axis 11 of the high and low beam combined lens unit 1, such as Figure 11 As shown, the central bright spot of the low beam light pattern projected after passing through the high and low beam combined lens unit 1 will be at a position farther from the HV intersection, such as being located near 17° away from the HV intersection on the photometric screen, increasing the energy of the low beam light pattern broadening and improving the irradiation width of the low beam towards the distance. It can be understood that Figure 9 This is just one embodiment. When looking down from above the high and low beam combined unit system, the arrangement positions of the high beam light source 4 and the high beam primary optical element 5 are not limited to being on the optical axis 11 of the high and low beam combined lens unit 1 as described above, and can also be at a position close to the optical axis 11 of the high and low beam combined lens unit 1. Correspondingly, the low beam light source 2 and the low beam primary optical element 3 can also be selected according to the design requirements.

[0075] In the high and low beam combined unit system, the distance between the low beam light source 2 and the optical axis 11 of the high and low beam combined lens unit 1 can be designed to be less than the distance between the high beam light source 4 and the optical axis 11 of the high and low beam combined lens unit 1. For example, referring to Figure 9 , the positions of the low beam light source 2 and the low beam primary optical element 3 and the high beam light source 4 and the high beam primary optical element 5 are interchanged. As seen from above the high and low beam combined unit system, the low beam light source 2 and the low beam primary optical element 3 are approximately located on the optical axis 11 of the high and low beam combined lens unit 1 or at a position close to the optical axis 11 of the high and low beam combined lens unit 1, that is, the low beam light source 2 is located on the optical axis 11 of the high and low beam combined lens unit 1 or at a position close to the optical axis 11 of the high and low beam combined lens unit 1; correspondingly, the high beam light source 4 and the high beam primary optical element 5 are located at a position farther from the optical axis 11 of the high and low beam combined lens unit 1, that is, the high beam light source 4 is located at a position farther from the optical axis 11 of the high and low beam combined lens unit 1. Or, in the high and low beam combined unit system, the distance between the low beam light source 2 and the optical axis 11 of the high and low beam combined lens unit 1 can be designed to be equal to the distance between the high beam light source 4 and the optical axis 11 of the high and low beam combined lens unit 1, that is, the low beam light source 2 unit and the high beam light source 4 are symmetrically arranged with respect to the optical axis 11 of the high and low beam combined lens unit 1. Or, the positional relationship between the low beam light source 2 and the low beam primary optical element 3 and the high beam light source 4 and the high beam primary optical element 5 can also be arranged in other ways according to the design requirements.

[0076] In some embodiments, both the low-beam primary optical element 3 and the high-beam primary optical element 5 are reflectors. As Figure 4 shown, for the low-beam primary optical element 3, a cut-off line forming structure 31 can be provided at the edge of the low-beam primary optical element 3. Exemplarily, as Figure 5 shown, the low-beam unit system located in the middle position can be used to increase the broadening on the left side of the low-beam light pattern. As Figure 8 shown, the high-low beam combination unit system located on the far right can be used to increase the broadening on the right side of the low-beam light pattern. As Figure 6 and Figure 7 shown, the two low-beam unit systems located between the above-mentioned low-beam unit system and the high-low beam combination unit system can be used to form the part of the low-beam light pattern with a low-beam cut-off line; as Figure 11 shown, thus forming the overall low-beam light pattern. In addition, a cut-off line forming structure 31 can also be provided at the edge of some or all of the low-beam primary elements 5 according to requirements, so that the required light pattern with a low-beam cut-off line is formed after all the low-beam light patterns are superimposed. The surface shape of the reflector can be a parabolic shape or an ellipsoidal shape, forming a parabolic reflector or an ellipsoidal reflector. For example, as Figure 1 shown, the low-beam primary optical element 3 of the low-beam unit system located in the middle can be an ellipsoidal reflector, which is beneficial to increasing the lateral broadening of the light pattern; the low-beam primary optical elements 3 of the low-beam unit systems located on both sides, the high-beam primary optical elements 5 of the high-beam unit systems, and the low-beam and high-beam primary optical elements 3 and 5 of the high-low beam combination unit system can be parabolic reflectors, which are beneficial to focusing the bright spot.

[0077] In some embodiments, the low-beam primary optical element 3 and / or the high-beam primary optical element 5 corresponding to the same lens unit are connected as a whole through a structure or integrally formed, and collimate the light sources corresponding to them respectively.

[0078] In some embodiments, the lens units are arranged in sequence along the transverse direction and connected as a whole or integrally formed. The light-emitting surface of the lens unit can be made into a free-form surface as a whole, and the light-incident surface of different lens units is generated according to configurations such as focal length. The lens unit images the corresponding primary optical element. Specifically, the light-emitting surfaces of the low-beam lens units 6 of the low-beam unit system, the high-beam lens units 7 of the high-beam unit system, and the high-low beam combination lens units 1 of the high-low beam combination unit system can be made into free-form surfaces in sequence, so that the low-beam lens units 6 of the low-beam unit system, the high-beam lens units 7 of the high-beam unit system, and the high-low beam combination lens units 1 of the high-low beam combination unit system are connected as a whole or integrally formed in sequence; the formed integral lens can be produced by an integral injection molding method.

[0079] In some embodiments, among the respective unit optical systems arranged in sequence in the transverse direction, the thickness of the lens unit corresponding to the middle unit optical system is less than the thicknesses of the lens units corresponding to the remaining unit optical systems. For example, as Figure 1 shown, the thickness of the low beam lens unit 6 in the middle is less than the thicknesses of the low beam lens units 6, the high beam lens unit 7, and the high and low beam combined lens unit 1 on both sides; or, as Figure 9 shown, the thickness of the low beam lens unit 6 in the middle is less than the thicknesses of the low beam lens units 6 and the high and low beam combined lens unit 1 on both sides. It can be understood that since in the respective unit optical systems arranged in sequence, it is not limited that the low beam unit system is arranged in the middle position. Therefore, when the high beam unit system or the high and low beam combined unit system is arranged in the middle position, the thickness of the corresponding high beam lens unit 7 or the thickness of the high and low beam combined lens unit 1 can also be less than the thicknesses of the low beam lens units 6, the high beam lens unit 7, and the high and low beam combined lens unit 1 on both sides. Thus, this design method of the lens thickness can, on the one hand, obtain a more aesthetic appearance image, and on the other hand, is beneficial to the overall injection molding production of the lens.

[0080] In some embodiments, among the respective unit optical systems arranged in sequence in the transverse direction, the lens unit corresponding to the middle unit optical system has a vertically focused incident light surface. For example, as Figures 17 to 20 shown, when viewed from above, the incident light surface of the low beam lens unit 6 in the middle focuses light only in the vertical direction, making the cut-off line of the low beam light pattern formed clearer; specifically, Figure 21 is a top view of the low beam lens unit 6 in the middle. It can be seen that the incident light surface of the low beam lens unit 6 in the middle is an inwardly concave arc in the horizontal direction. Figure 22 is Figure 21 a vertical cross-section of the low beam lens unit 6 in Figure 23 It can be seen that the incident light surface of the low beam lens unit 6 in the middle is approximately a straight line in the vertical direction. Moreover, Figure 24 is Figure 23 a horizontal cross-section of the low beam lens 6 in

[0081] It can be seen that the incident light surface of the low beam lens unit 6 in the middle is an inwardly concave arc in the horizontal direction, so as to achieve the effect that the incident light surface of the low beam lens unit 6 in the middle focuses light only in the vertical direction. Of course, the unit optical system corresponding to the lens unit in the middle position is not limited to the above low beam unit system, and can also be a high beam unit system or a high and low beam combined unit system.

[0081] In some embodiments, among the respective unit optical systems arranged in sequence in the transverse direction, the outermost unit optical system has at least two primary optical elements. As Figure 1As shown, the outermost unit optical systems are a high beam unit system and a high and low beam combined unit system respectively. The high beam unit system has two high beam primary optical elements 5, and the high and low beam combined unit system has a low beam primary optical element 3 and a high beam primary optical element 5. If the above high beam unit system or high and low beam combined unit system is arranged in the middle position, due to the fact that the high beam unit system has two high beam primary optical elements 5 or the high and low beam combined unit system has a low beam primary optical element 3 and a high beam primary optical element 5, the spatial arrangement will be relatively crowded, which is likely to cause interference in the arrangement positions of each unit optical system. However, arranging the above high beam unit system or high and low beam combined unit system on the outermost side can effectively increase the effective space of the system, making the arrangement more reasonable. Similarly, as Figure 16 shown, arranging the high and low beam combined unit system on the outermost side can effectively increase the effective space of the system, making the arrangement more reasonable.

[0082] In some embodiments, a baffle 8 is provided between two adjacent unit optical systems, which can separate the light sources and reflectors of different unit optical systems, preventing light leakage between the unit optical systems. For example, as Figure 1 or Figure 9 shown, a baffle 8 is provided between the adjacent low beam unit system, high beam unit system and high and low beam combined unit system, making the adjacent low beam unit system, high beam unit system and high and low beam combined unit system independent of each other. The baffle 8 can be integrally formed with the reflector. For example, the baffle 8 is integrally formed with the corresponding low beam primary optical element 3, and the baffle 8 is integrally formed with the corresponding high beam primary optical element 5. Alternatively, a heat dissipation structure, such as a radiator, can also be provided, and each baffle 8 is integrally formed with the radiator.

[0083] In some embodiments, a light diffusion structure 9 is provided on the light incident surface of the lens unit corresponding to each unit optical system. For example, as Figure 2 shown, a light diffusion structure 9 is provided on the light incident surfaces of the low beam lens unit 6 corresponding to the low beam unit system, the high beam lens unit 7 corresponding to the high beam unit system, and the high and low beam combined lens unit 1 corresponding to the high and low beam combined unit system. The light diffusion structure 9 is used to diffuse light. Specifically, the light diffusion structure 9 can be a pattern, and the pattern can be a structure suitable for light diffusion.

[0084] In some embodiments, both the low beam light source 2 and the high beam light source 4 are placed on the same circuit board.

[0085] To better understand the technical concept of the present invention, the following is described in combination with relatively comprehensive technical features.

[0086] As Figures 1 to 16As shown in the figure, a preferred embodiment of the present invention provides a dual-light module for implementing low-beam and high-beam functions. The dual-light module includes a lens and a plurality of unit optical systems. Each unit optical system includes a primary optical element and a light source. The unit optical systems are arranged in sequence along the transverse direction. The lens has a plurality of lens units connected in sequence. Each unit optical system is correspondingly arranged with each lens unit. According to different functions to be realized, each lens unit can be divided into a low-beam and high-beam combined lens unit 1, a low-beam lens unit 6, and a high-beam lens unit 7. Some of the unit optical systems in each unit optical system can be low-beam unit systems, some of the unit optical systems in each unit optical system can be high-beam unit systems, and some of the unit optical systems in each unit optical system can be low-beam and high-beam combined unit systems, as long as at least one unit optical system is a low-beam and high-beam combined unit system. As Figure 1 shown, among the unit optical systems arranged in sequence along the transverse direction, three low-beam unit systems are arranged in the middle position, three high-beam unit systems are arranged on the left side, and one low-beam and high-beam combined unit system is arranged on the right side. Or, as Figure 14As shown, in each unit optical system arranged in sequence along the horizontal direction, two low beam unit systems are arranged in the middle position, and a high and low beam combined unit system is arranged on each of the left and right sides of the two low beam unit systems. The low beam unit system includes at least one low beam light source 2 and at least one low beam primary optical element 3. Each low beam primary optical element 3 is configured to collimate the light emitted by the corresponding low beam light source 2 towards the low beam lens unit 6 and form an image through the low beam lens unit 6. The high beam unit system includes at least one high beam light source 4 and at least one high beam primary optical element 5. Each high beam primary optical element 5 is configured to collimate the light emitted by the corresponding high beam light source 4 towards the high beam lens unit 7 and form an image through the high beam lens unit 7. The high and low beam combined unit system includes a low beam light source 2, a low beam primary optical element 3, a high beam light source 4, and a high beam primary optical element 5. The low beam primary optical element 3 is configured to collimate the light emitted by the low beam light source 2 towards the high and low beam combined lens unit 1 and form an image through the high and low beam combined lens unit 1. The high beam primary optical element 5 is configured to collimate the light emitted by the high beam light source 4 towards the high and low beam combined lens unit 1 and form an image through the high and low beam combined lens unit 1. Both the low beam primary optical element 3 and the high beam primary optical element 5 are reflectors. Specifically, the reflector can be a parabolic reflector or an ellipsoidal reflector. The lens units corresponding to each unit optical system are connected as a whole or integrally formed. The light-emitting surface of the lens unit can be made into a free-form surface as a whole, and the light-incident surface of different lens units is generated according to configurations such as focal length. The lens unit forms an image of the corresponding reflector. Specifically, the light-emitting surface of the low beam lens unit 6 and the light-emitting surface of the high and low beam combined lens unit 1 can be made into free-form surfaces in sequence, so that the low beam lens unit 6, the high beam lens unit 7, and the high and low beam combined lens unit 1 are connected as a whole or integrally formed in sequence; the formed integral lens can be produced by an integral injection molding method. In each unit optical system arranged in sequence, the thickness of the lens unit corresponding to the middle unit optical system is smaller than the thickness of the lenses corresponding to the remaining unit optical systems. In each unit optical system arranged in sequence, the lens unit corresponding to the middle unit optical system has a vertically focused light-incident surface. A baffle 8 is arranged between two adjacent unit optical systems, which can separate the light sources and reflectors of different unit optical systems and prevent light leakage between the unit optical systems. A light diffusion structure 9 is arranged on the light-incident surface of the lens of each unit optical system. The light diffusion structure 9 can be a pattern, and the pattern can be a structure suitable for light diffusion.

[0087] In the case of the low beam mode and the high beam mode, the corresponding lenses can be lit. For the dual-beam module, in the low beam mode, the lens unit corresponding to the low and high beam combination unit system can be lit, and there is no need to add additional cost and structure to achieve the high beam accompanying lighting effect in the low beam mode, and a good appearance of the vehicle lamp lighting can also be obtained. In the low beam mode, only the low beam light source 6 of the low and high beam combination unit system is lit, and the low beam light source 6 is more dispersed, which can improve the thermal risk of the system and at the same time improve the low beam optical efficiency. The dispersion angle of the low beam light is large enough to effectively increase the low beam width.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, including any suitable combination of each specific technical feature.
