[0054] The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are intended to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. The present invention can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but rather includes all technical solutions within the scope of the claims.

It should be noted that: unless otherwise specifically stated, the relative arrangement of parts and steps, the composition of materials, numerical expressions and numerical values ​​set forth in these embodiments should be interpreted as merely exemplary, and not as limiting.

[0056] It should be noted that, for the convenience of describing the present invention and simplifying the description, the dual-light module is generally arranged in the same orientation as when the headlight is actually used on a vehicle. For example, the lens is in front, and the primary optical element is in the back. The horizontal arrangement of the individual unit optical systems means that the individual unit optical systems are arranged approximately in the left-right direction, and the vertical arrangement means that the individual unit optical systems are arranged approximately in 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, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0057] In addition, words such as “include” or “comprise” and the like used in the present invention mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of also including other elements.

[0058] It should also be noted that, in the description of this invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; they can be directly connected or indirectly connected through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this invention depending on the specific circumstances. When a specific device is described as being located between a first device and a second device, there may or may not be an intervening device between the specific device and the first or second device.

[0059] All terms used herein have the same meanings as understood by one of ordinary skill in the art to which the present invention belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, common dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0060] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0061] As shown in Figures 1 to 3 and Figures 14 to 16, an embodiment of the present invention provides a dual-light module for realizing low beam function and high beam function, the dual-light module includes a lens and several 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 horizontal direction, the lens has several lens units connected in sequence, and each unit optical system is respectively arranged corresponding to each lens unit; and at least one of each unit optical system is a high and low beam combination unit system, the high and low beam combination 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 high and low beam combination unit system corresponds to a high and low beam combination lens unit 1, the low beam primary optical element 3 is configured to be able to collimate the light emitted by the low beam light source 2 to the high and low beam combination lens unit 1 and to form an image after being projected by the high and low beam combination lens unit 1, the high beam primary optical element 5 is configured to be able to collimate the light emitted by the high beam light source 4 to the high and low beam combination lens unit 1 and to form an image after being projected by the high and low beam combination lens unit 1.

[0062] Based on the above technical solution, the dual-light module of the present invention arranges multiple unit optical systems in sequence along the horizontal direction. Each unit optical system is independent and corresponds to different lens units, which are used to achieve different functions. The light source is more dispersed, which can improve the thermal risk of the system. Moreover, among the unit optical systems, at least one is a high and low beam combination unit system. The high and low beam combination 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 passes through the low beam primary optical element 3 and the high and low beam combination lens unit 1 to form a low beam light pattern. The light emitted by the high beam light source 4 passes through the high beam primary optical element 5 and the high and low beam combination lens unit 1 to form a high beam light pattern. The low beam and high beam share the high and low beam combination lens unit 1. Without affecting the high beam, the addition of a low-beam light source 2 and a low-beam primary optical element 3 to the high-beam unit system transforms the high-beam unit system into a combined high- and low-beam unit system. This design increases the spread of the low-beam light pattern. Furthermore, since no additional low-beam light source 2 and low-beam primary optical element 3 are provided in the low-beam unit system, the low-beam light sources 2 are not excessively clustered, creating thermal risks. Therefore, compared to the prior art, which requires the addition of a low-beam module to increase the spread of the low-beam light pattern, the present invention offers a simple, reliable, and relatively low-cost solution.

[0063] It should be noted that, each lens unit can be divided into a high- and low-beam combined lens unit 1 , a low-beam lens unit 6 and a high-beam lens unit 7 according to different functions.

[0064] In traditional high and low beam lighting modules, in low beam mode, the lens area corresponding to the high beam module is not illuminated, and the appearance of the headlight is not good. In order to obtain a good headlight lighting appearance, it is necessary to actively illuminate the lens area corresponding to the high beam module to achieve the high beam accompanying lighting effect in low beam mode. This method not only causes a certain amount of energy waste, but also requires additional components to achieve accompanying lighting, which increases cost. For example, in the dual light module of the present invention, part of the unit optical system can be selected as the low beam unit system, and the remaining unit optical system can be selected as the high and low beam combination unit system. For the high and low beam combination unit system, its low beam mode (low beam light source 2 and low beam primary optical element 3 are used to form the low beam light pattern) and the high beam mode (high beam light source 4 and high beam primary optical element 5 are used to form the high beam light pattern) share the high and low beam combination lens unit 1. In low beam mode, the corresponding lens unit and the high and low beam combination lens unit 1 can be illuminated together, and there is no need to add additional components to achieve the high beam accompanying lighting effect in low beam mode, thereby obtaining a good headlight lighting appearance.

[0065] Specifically, Figures 14 to 16 provide an embodiment of a dual-beam module. Two low-beam unit systems are arranged in a central position, with a high- and low-beam combination unit system positioned on either side of each 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 unit system has a corresponding low-beam lens unit 6. Each low-beam primary optical element 3 is configured to collimate light emitted by the corresponding low-beam light source 2 toward the low-beam lens unit 6, where it forms an image. In low-beam mode, the low-beam light source 2 in the low-beam unit system is illuminated, and simultaneously, the low-beam light source 2 in the high- and low-beam combination unit system is illuminated. The low-beam light source 2 in the high- and low-beam combination unit system provides a sufficiently large dispersion angle for widening the low-beam pattern. Furthermore, because the low-beam light source 2 in the high- and low-beam combination unit system is not located in the low-beam unit system, the low-beam light sources 2 are more dispersed, which improves the thermal risk of the system and enhances the optical efficiency of the low beam.

[0066] It should be noted that for the low-beam unit system, the number of low-beam light sources 2 and low-beam primary optical elements 3 arranged therein can be selected based on design requirements. Furthermore, the number of low-beam unit systems and high-low beam combination unit systems can be selected based on design requirements. The positional relationship between the low-beam unit system and the high-low beam combination unit system can also be selected based on design requirements. For example, the low-beam unit system can be arranged in the middle position, and the high-low beam combination unit system can be arranged outside the low-beam unit system; or the high-low beam combination unit system can be arranged in the middle position, and the low-beam unit system can be arranged outside the high-low beam combination unit system; or the low-beam unit system and the high-low beam combination unit system can be arranged in another order.

[0067] In some embodiments, a high-beam unit system, a low-beam unit system, and a high- and low-beam combination unit system can also be arranged in a dual-light module, with some of the unit optical systems selected as high-beam unit systems, some of the unit optical systems selected as low-beam unit systems, and the remaining unit optical systems selected as high- and low-beam combination unit systems. Figures 1 to 3 provide another embodiment of a dual-light module, in which three low-beam unit systems are arranged in the middle position, three high-beam unit systems are arranged on the left, and one high- and low-beam combination unit system is arranged on the right. 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 toward the high-beam lens unit 7 and form an image through the high-beam lens unit 7. In the high beam mode, the high beam light source 4 in the high beam unit system is lit, and at the same time, the high beam light source 4 in the high and low beam combination unit system is also lit, so that the high beam light dispersion angle is large enough, which can be used to increase the widening of the high beam light pattern. Moreover, since the high beam light source 4 in the high and low beam combination unit system is not set in the high beam unit system, the high beam light source 4 is set more dispersed, which can improve the thermal risk of the system and improve the high beam optical efficiency.

[0068] It should be noted that, for the high-beam unit system, the number of high-beam light sources 4 and high-beam primary optical elements 5 arranged therein can be selected according to design requirements. Furthermore, the number of high-beam unit systems, low-beam unit systems, and high- and low-beam combination unit systems can be selected according to design requirements. The positional relationship between the high-beam unit systems, low-beam unit systems, and high- and low-beam combination unit systems can also be arranged according to design requirements. For example, the low-beam unit system can be arranged in the middle position, with the high-beam unit system arranged on the left and the high- and low-beam combination unit system arranged on the right; or the high- and low-beam combination unit system can be arranged in the middle position, the low-beam unit system can be arranged on the right, and the high-beam unit system can be arranged on the left; or the high-beam unit system can be arranged in the middle position, the high- and low-beam combination unit system can be arranged on the right, and the low-beam unit system can be arranged on the left; or the high-beam unit system can be arranged in the middle position, the high- and low-beam combination unit system can be arranged on the right, and the low-beam unit system can be arranged on the left; or the high-beam unit system, low-beam unit system, and high- and low-beam combination unit system can be arranged in any other order.

[0069] In addition, in addition to adopting the combination of the above-mentioned low beam unit system and the high and low beam combination unit system, or the combination of the above-mentioned high beam unit system, low beam unit system and high and low beam combination unit system, the dual-light module can also adopt a combination of several high and low beam combination unit systems or a combination of a high beam unit system and a high and low beam combination unit system. These combinations can all achieve the technical effects of the dual-light module.

[0070] 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 shows an embodiment 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 roughly 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, as shown in Figures 12 and 13, 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 focus of the high and low beam combination lens unit 1. Preferably, the distance between the high beam light source 4 and the focus 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 in the focal plane of the high and low beam combination lens unit 1. The light is emitted from the focus, and after passing through the high and low beam combination lens unit 1, the light is parallel to the optical axis 11; the light is emitted from a place far away from the focus, and after passing through the high and low beam combination lens unit 1, the light forms an angle with the optical axis 11. The farther the high beam light source 4 is from the focus, the greater the angle. Therefore, in the embodiment of Figure 9, as shown in Figure 10, the central bright spot of the high beam light type projected by the high and low beam combination lens unit 1 is located near the HV intersection position on the light distribution screen, that is, the high beam light is 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 farther from the optical axis 11 of the high and low beam combination lens unit 1. Therefore, in the embodiment of Figure 9, as shown in Figure 11, the central bright spot of the low beam light type projected after passing through the high and low beam combination lens unit 1 will be at a position farther from the HV intersection.

[0071] It should be noted that the light patterns shown in Figures 10 and 11 refer to the projection shape of the headlight light onto a light distribution screen 25 meters from the front of the vehicle. The light distribution screen is typically divided into areas using horizontal lines H and vertical lines V. As shown in Figure 9, the high-beam light source 4 and the high-beam primary optical element 5 are located on or near the optical axis 11 of the high- and low-beam combination lens unit 1. As shown in Figure 10, the central bright spot of the high-beam light pattern projected after passing through the high- and low-beam combination lens unit 1 is located near the HV intersection on the light distribution screen, which can increase the illumination in the HV intersection area and improve the high-beam illumination distance. Accordingly, as shown in FIG9 , the low-beam light source 2 and the low-beam primary optical element 3 are located at a position relatively far from the optical axis 11 of the high- and low-beam combination lens unit 1. As shown in FIG11 , 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 located at a position relatively far from the HV intersection, such as being located approximately 17° away from the HV intersection on the light distribution screen, thereby increasing the energy of the low-beam light pattern broadening and improving the illumination width of the low-beam light to a distant direction. It will be understood that FIG9 is merely an embodiment. When viewed from above the high- and low-beam combination 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 located on the optical axis 11 of the high- and low-beam combination lens unit 1 as described above, but may also be located near the optical axis 11 of the high- and low-beam combination lens unit 1. Accordingly, the low-beam light source 2 and the low-beam primary optical element 3 may also be selected according to design requirements.

[0072] 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 can be designed to be smaller 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. 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. When viewed from above the high and low beam combination unit system, the low beam light source 2 and the low beam primary optical element 3 are roughly 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, the low beam light source 2 is 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; accordingly, the high beam light source 4 and the high beam primary optical element 5 are located farther from the optical axis 11 of the high and low beam combination lens unit 1, that is, the high beam light source 4 is located farther from the optical axis 11 of the high and low beam combination lens unit 1. Alternatively, 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 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 combination lens unit 1, that is, the low beam light source 2 and the high beam light source 4 are symmetrically arranged about the optical axis 11 of the high and low beam combination lens unit 1. Alternatively, 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 be arranged in other ways according to design requirements.

[0073] In some embodiments, both the low-beam primary optical element 3 and the high-beam primary optical element 5 are reflectors. As shown in FIG4 , a cutoff-forming structure 31 can be provided on the edge of the low-beam primary optical element 3 . For example, as shown in FIG5 , the middle low-beam unit system can be used to increase the left-side spread of the low-beam pattern. As shown in FIG8 , the rightmost high-low-beam combination unit system can be used to increase the right-side spread of the low-beam pattern. As shown in FIG6 and FIG7 , the two low-beam units located between the low-beam unit system and the high-low-beam combination unit system can be used to form a portion of the low-beam pattern with a low-beam cutoff. As shown in FIG11 , the overall low-beam pattern is thus formed. Furthermore, as needed, a cutoff-forming structure 31 can be provided on the edges of some or all of the low-beam primary optical elements 5 so that all low-beam patterns are superimposed to form the desired pattern with a low-beam cutoff. The reflector surface can be parabolic or ellipsoidal, forming a parabolic reflector or an ellipsoidal reflector. For example, as shown in Figure 1, 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 increase the lateral widening of the light pattern; the low beam primary optical element 3 of the low beam unit system, the high beam primary optical element 5 of the high beam unit system on both sides, and the low beam primary optical element 3 and the high beam primary optical element 5 of the high and low beam combination unit system can be parabolic reflectors, which is beneficial to focusing the bright spot.

[0074] 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 structurally connected as one or integrally formed to collimate their respective corresponding light sources.

[0075] In some embodiments, the lens units are arranged in sequence along the horizontal direction and connected as a whole or formed as a whole. The light-emitting surface of the lens unit can be made into a free-form surface as a whole. Different light-incident surfaces of the lens units are generated according to the configuration such as focal length, and the lens units form images for the corresponding primary optical elements. Specifically, the light-emitting surface of the low-beam lens unit 6 of the low-beam unit system, the light-emitting surface of the high-beam lens unit 7 of the high-beam unit system, and the light-emitting surface of the high-beam and low-beam combination lens unit 1 of the high-beam and low-beam combination unit system can be made into free-form surfaces in sequence, so that the low-beam lens unit 6 of the low-beam unit system, the high-beam lens unit 7 of the high-beam unit system, and the high-beam and low-beam combination lens unit 1 of the high-beam and low-beam combination unit system are connected in sequence as a whole or formed as a whole. The formed integral lens can be produced by integral injection molding.

[0076] In some embodiments, within each laterally arranged unit optical system, the thickness of the lens unit corresponding to the center unit optical system is thinner than the thickness of the lens units corresponding to the remaining unit optical systems. For example, as shown in Figure 1, the thickness of the center low-beam lens unit 6 is thinner than the thickness of the adjacent low-beam lens units 6, high-beam lens unit 7, and high-low beam combination lens unit 1. Alternatively, as shown in Figure 9, the thickness of the center low-beam lens unit 6 is thinner than the thickness of the adjacent low-beam lens units 6 and high-low beam combination lens unit 1. It will be appreciated that, since the low-beam unit system is not limited to being positioned in the center of the sequentially arranged unit optical systems, if a high-beam unit system or a high-low beam combination lens system is positioned in the center, the thickness of the corresponding high-beam lens unit 7 or high-low beam combination lens unit 1 can also be thinner than the thickness of the adjacent low-beam lens units 6, high-beam lens unit 7, and high-low beam combination lens unit 1. This lens thickness design approach not only achieves a more aesthetically pleasing appearance, but also facilitates the production of integral lens injection molding.

[0077] In some embodiments, among the unit optical systems arranged in sequence along the transverse direction, the lens unit corresponding to the middle unit optical system has a vertical focusing light incident surface. For example, as shown in Figures 17 to 20, when viewed from above, the light incident surface of the low beam lens unit 6 located in the middle focuses the light only in the vertical direction, so that the low beam cut-off line of the low beam light type formed is clearer; specifically, Figure 21 is a top view of the low beam lens unit 6 located in the middle. It can be seen that the light incident surface of the low beam lens unit 6 located in the middle is an inwardly concave arc in the horizontal direction. Figure 22 is a cross-sectional view of the low beam lens unit 6 in Figure 21 along the vertical direction. It can be seen that the light incident surface of the low beam lens unit 6 located in the middle is approximately a straight line in the vertical direction. Moreover, Figure 23 is a side view of the low beam lens unit 6 located in the middle. Figure 24 is a cross-sectional view of the low beam lens 6 in Figure 23 along the horizontal direction. It can be seen that the light incident surface of the low beam lens unit 6 located in the middle is an inwardly concave arc in the horizontal direction, thereby achieving the effect that the light incident surface of the low beam lens unit 6 located in the middle focuses the light only in the vertical direction. Of course, the unit optical system to which the lens unit in the middle position corresponds is not limited to the above-mentioned low beam unit system, and may also be a high beam unit system or a high and low beam combination unit system.

[0078] In some embodiments, among the unit optical systems arranged in sequence along the horizontal direction, the outermost unit optical system has at least two primary optical elements. As shown in FIG1 , the outermost unit optical systems are a high-beam unit system and a high-low beam combination unit system. The high-beam unit system has two high-beam primary optical elements 5, and the high-low beam combination unit system has one low-beam primary optical element 3 and one high-beam primary optical element 5. If the high-beam unit system or the high-low beam combination unit system is arranged in the middle position, the high-beam unit system has two high-beam primary optical elements 5, or the high-low beam combination unit system has one low-beam primary optical element 3 and one high-beam primary optical element 5, the spatial arrangement will be relatively crowded, which may easily cause interference between the individual unit optical systems in their arrangement positions. However, placing the high-beam unit system or the high-low beam combination unit system at the outermost position can effectively increase the effective space of the system, making the arrangement more reasonable. Similarly, as shown in FIG16 , placing the high-low beam combination unit system at the outermost position can effectively increase the effective space of the system, making the arrangement more reasonable.

[0079] In some embodiments, a baffle 8 is provided between two adjacent unit optical systems to separate the light sources and reflectors of the different unit optical systems and prevent crosstalk between the unit optical systems. For example, as shown in Figures 1 or 9, baffles 8 are provided between adjacent low-beam unit systems, high-beam unit systems, and high-low beam combination unit systems, ensuring that the adjacent low-beam unit systems, high-beam unit systems, and high-low beam combination unit systems are mutually independent. The baffle 8 can be integrated with the reflector, such as with the corresponding low-beam primary optical element 3, or with the corresponding high-beam primary optical element 5. Alternatively, a heat dissipation structure, such as a heat sink, can be provided, with each baffle 8 integrated with the heat sink.

[0080] In some embodiments, the light-entering surfaces of the lens units corresponding to each unit optical system are provided with a light-diffusing structure 9. For example, as shown in FIG2 , the light-entering surfaces of the low-beam lens unit 6 corresponding to the low-beam unit system, the light-entering surface of the high-beam lens unit 7 corresponding to the high-beam unit system, and the light-entering surface of the high-low-beam combined lens unit 1 corresponding to the high-low-beam combined unit system are provided with a light-diffusing structure 9. The light-diffusing structure 9 is used to diffuse light. Specifically, the light-diffusing structure 9 can be a pattern, and the pattern can be a structure suitable for light diffusion.

[0081] In some embodiments, the low-beam light source 2 and the high-beam light source 4 are both placed on the same circuit board.

[0082] In order to better understand the technical concept of the present invention, the following is an explanation in combination with relatively comprehensive technical features.

[0083] As shown in Figures 1 to 16, a preferred embodiment of the present invention provides a dual-light module for realizing low-beam and high-beam functions. The dual-light module includes a lens and several unit optical systems. The unit optical systems include primary optical elements and light sources. Each unit optical system is arranged in sequence along the horizontal direction. The lens has several lens units connected in sequence. Each unit optical system is respectively arranged corresponding to each lens unit. Each lens unit can be divided into a high-beam and low-beam combination lens unit 1, a low-beam lens unit 6, and a high-beam lens unit 7 according to the different functions to be realized. 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 high-beam combination unit systems, as long as at least one unit optical system is a high-beam combination unit system. As shown in Figure 1, in each unit optical system arranged in sequence along the horizontal direction, three low-beam unit systems are arranged in the middle position, three high-beam unit systems are arranged on the left, and one high-beam combination unit system is arranged on the right. Alternatively, as shown in Figure 14, among the various unit optical systems arranged in sequence along the horizontal direction, two low-beam unit systems are arranged in the middle position, and a high-beam and low-beam combination unit system is arranged on 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 toward 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 toward the high-beam lens unit 7, and form an image through the high-beam lens unit 7. The high and low beam combination 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 to the high and low beam combination lens unit 1 and form an image through the high and low beam combination lens unit 1. The high beam primary optical element 5 is configured to collimate the light emitted by the high beam light source 4 to the high and low beam combination lens unit 1 and form an image through the high and low beam combination lens unit 1. The low beam primary optical element 3 and the high beam primary optical element 5 are both 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 one body or formed as one body. The light emitting surface of the lens unit can be made into a free-form surface as a whole. Different light incident surfaces of the lens units are generated according to the configuration such as focal length, and the lens units form images on the corresponding reflectors.Specifically, the light-emitting surface of the low-beam lens unit 6 and the light-emitting surface of the high-beam and low-beam combination 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-beam and low-beam combination lens unit 1 are connected in sequence as a whole or formed as a whole; the lens formed in the form of an integral whole can be produced by integral injection molding. In each unit optical system arranged in sequence, the thickness of the lens unit corresponding to the middle unit optical system is less than the thickness of the lens 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 provided between two adjacent unit optical systems to separate the light sources and reflectors of different unit optical systems to prevent light from crossing between the unit optical systems. The light incident surface of the lens of each unit optical system is provided with a light diffusion structure 9. The light diffusion structure 9 can be a pattern, and the pattern can be a structure suitable for light diffusion.

[0084] In both low-beam and high-beam modes, the corresponding lenses are illuminated. For dual-beam modules, in low-beam mode, the corresponding lens units of the high- and low-beam combination system are illuminated. This eliminates the need for the added cost and structure of a high-beam accompanying lighting effect in low-beam mode, while still achieving a good lighting appearance. In low-beam mode, only the low-beam light source 6 of the high- and low-beam combination system is illuminated, making the low-beam light source 6 more dispersed, improving the system's thermal risk and enhancing low-beam optical efficiency. The low-beam light dispersion angle is sufficiently large to effectively increase the low-beam spread.

[0086] An embodiment of the present invention further provides a vehicle provided with the above-mentioned headlight, that is, adopting all the technical solutions of the above-mentioned headlight embodiment, and therefore having at least all the beneficial effects brought about by the technical solutions of the above-mentioned headlight embodiment.

[0087] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, the technical solution of the present invention may be subjected to a variety of simple modifications, including combining the various specific technical features in any suitable manner.
