[0002] In related technologies, the improvement of high and low beam brightness in dual-beam modules is limited by the opening, which basically cannot meet the road illumination performance indicators of high-end vehicles in the market. Generally, multiple modules are added to improve brightness, but the shape cannot be flat and integrated, and there is easy light path interference between multiple modules, which affects the light output effect. Utility Model Content

[0003] This application provides a dual-beam module and vehicle headlight, which improves upon the related technology that increases brightness by adding multiple modules, but the shape cannot be flat and integrated, and there is easy light path interference between multiple modules, affecting the light output effect.

[0004] Firstly, a light-emitting structure is provided, including a low beam cutoff module, a low beam broadening module, a high beam broadening module, and a high beam converging module. The low beam cutoff module includes a first light source, a first focusing element located on the light output path of the first light source, a cutoff structure, and a first focal lens; The low beam broadening module includes a second light source, a second focusing element and a first focal line lens located on the light output path of the second light source; The high beam extension module includes a third light source, a third light-concentrating element located on the light output path of the third light source, and a second focal line lens; The high beam converging module includes a fourth light source, a fourth light-concentrating element located on the light output path of the fourth light source, and a second focal lens; The first focal lens, the first focal line lens, the second focal line lens, and the second focal lens are integrated into a single structure and form an outer lens. The light-emitting surface of the outer lens participates in the construction of the appearance surface of the dual-light module, and the light-emitting surface is smooth.

[0005] The dual-light module of this application embodiment unifies the optical functions into a smooth outer lens light-emitting surface. This light-emitting surface directly constitutes the appearance component of the vehicle headlight, realizing a truly flat and integrated shape, and improving aesthetics and design freedom. On the other hand, through precision injection molding, the first focal lens, the first focal line lens, the second focal line lens, and the second focal lens are integrated on the same optical substrate. There are no physical seams between the first focal lens, the first focal line lens, the second focal line lens, and the second focal lens. When light passes through, there will be no stray light caused by scattering at the seams, and there will be no light-dark separation, thus ensuring light efficiency.

[0006] In some embodiments, the low beam cutoff module, the low beam widening module, the high beam widening module, and the high beam converging module are distributed along a first direction; The first focusing element, the cutoff line structure, and the first focal lens are distributed along the second direction; The light-emitting surface is a convex cylindrical surface that extends along the first direction and bends in the third direction, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0007] Based on the above embodiments, the low beam widening module, the high beam widening module, and the high beam converging module each have independent optical paths. The light spots of the low beam and the high beam only overlap and do not conflict in the first direction, and will not form dark slits due to competition for optical paths.

[0008] In some embodiments, the first focal lens includes a first light-incident surface, which is a convex cylindrical surface curved in a first direction; The first focal line lens includes a second light-incident surface, which is a plane perpendicular to the second direction; The second focal line lens includes a third light-incident surface, which is a plane perpendicular to the second direction; The second focal lens includes a fourth light-incident surface, which is a convex cylindrical surface curved in the first direction.

[0009] Based on the above embodiments, the arrangement of the first light-incident surface and the fourth light-incident surface, together with the convex cylindrical surface of the outer lens, enables the light beams passing through the first focal lens and the second focal lens to be focused, thereby forming the corresponding near-beam core region and far-beam core region. The setting of the second and third light-incident surfaces avoids light loss due to refraction when light enters the eye, and allows the near and far beams to be extended laterally.

[0010] In some embodiments, the second incident surface and the third incident surface are coplanar.

[0011] Based on the above embodiments, light can be guided to propagate more orderly, thereby reducing stray light generation, improving light efficiency and imaging quality, and effectively shortening the mold development cycle, reducing manufacturing difficulty and cost.

[0012] In some embodiments, the low beam cutoff module, the low beam widening module, the high beam widening module, and the high beam converging module are distributed sequentially along a first direction.

[0013] Based on the above embodiments, the light patterns emitted by the cutoff line module and the low beam widening module are in front (closer to the vehicle), while the light patterns emitted by the high beam widening module and the high beam converging module are behind (projected towards the distance). The low-angle light of the low beam will not interfere with the straight light of the high beam, reducing the possibility of stray light and dark spots.

[0014] In some embodiments, at least one of the first, second, third, and fourth focusing elements is a reflector bowl.

[0015] Based on the above embodiments, the reflector bowl achieves light reflection through a high-reflectivity coating such as aluminum film or silver film, which can converge the light with only one reflection, reducing the light loss rate and ensuring the light output efficiency.

[0016] In some embodiments, the dual-beam module further includes a lens bracket, which has a mounting cavity and a mounting port communicating with the mounting cavity. The low beam cutoff module, the low beam broadening module, the high beam broadening module, and the high beam converging module are all installed in the mounting cavity. The outer lens is installed in the mounting port, and the light-inlet surface of the outer lens is located inside the mounting cavity, while the light-outlet surface of the outer lens is located outside the mounting cavity.

[0017] Based on the above embodiments, the near beam cutoff module, near beam broadening module, far beam broadening module and far beam converging module are integrated into the same mounting cavity through a lens bracket, providing a common mounting reference for the optical components of each module.

[0018] In some embodiments, the first focusing element and the second focusing element are an integral structure; The third and fourth focusing elements are integrated into one structure.

[0019] Based on the above embodiments, it is equivalent to setting the relative positions of the low beam optical path and the high beam optical path in the physical structure, thereby ensuring that the core lighting area and the widening area of ​​the low beam, and the center lighting area and the surrounding wide area of ​​the high beam can be seamlessly and uniformly connected and superimposed, effectively avoiding the phenomenon of dark areas or uneven brightness, and significantly improving the lighting quality.

[0020] In some embodiments, the dual-light module further includes a first circuit board, a second circuit board, a third circuit board, and a fourth circuit board, with the first light source, the second light source, the third light source, and the fourth light source correspondingly disposed on the first circuit board, the second circuit board, the third circuit board, and the fourth circuit board. The dual-light module also includes a first heat dissipation component and a second heat dissipation component. The first circuit board and the second circuit board are disposed on the first heat dissipation component, and the first heat dissipation component, the third light-concentrating component, and the fourth light-concentrating component are integrated into one structure. The third and fourth circuit boards are mounted on the second heat dissipation assembly, and the second heat dissipation assembly is an integral structure with the first and second light-concentrating elements.

[0021] Based on the above embodiments, both the first heat dissipation component and the second heat dissipation component are heat dissipation structures with multiple heat dissipation plate arrays. By setting the first heat dissipation component and the second heat dissipation component, the heat on the first circuit board, the second circuit board, the third circuit board and the fourth circuit board can be effectively reduced, ensuring the stability of the light source and improving the service life of the entire dual-light module.

[0022] Secondly, a vehicle light is provided, including the aforementioned bi-beam module and dimming mechanism. Attached Figure Description

[0025] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0026] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] In related technologies, the improvement of high and low beam brightness in dual-beam modules is limited by the opening, which basically cannot meet the road illumination performance indicators of high-end vehicles in the market. Generally, multiple modules are added to improve brightness, but the shape cannot be flat and integrated, and there is easy light path interference between multiple modules, which affects the light output effect.

[0028] To resolve the above issues, please refer to [link / reference]. Figure 1 as well as Figure 2 This application provides a dual-beam module 1, including a low beam cutoff module 10, a low beam widening module 20, a high beam widening module 30, and a high beam converging module 40.

[0029] The low beam cutoff module 10 includes a first light source 11, a first focusing element 12 located on the light output path of the first light source 11, a cutoff structure 13, and a first focal lens 14.

[0030] like Figure 3 As shown, the first light source 11 provides the basic luminous flux, the first focusing element 12 collimates the light emitted by the first light source 11, and then the cutoff line structure 13 (such as a light shield) physically blocks part of the light to form the cutoff line of the low beam. Then, the light is focused by the first focal lens 14, which can use the refraction effect of the convex lens to focus the light emitted by the light source to a point to form a high energy density light spot.

[0031] It is important to understand that the cutoff line structure 13 is generally a plate-like structure, including a left baffle, a right baffle along the vehicle's direction of travel, and a ramp connecting the left and right baffles. The left baffle is higher and is usually located on the left side of the vehicle's direction of travel (on the opposite lane side), used to block upward-scattered light and prevent glare for oncoming vehicle drivers. The right baffle is lower and located on the right side of the vehicle (on the lane side), allowing light to be projected at a lower angle, illuminating the right side of the road and pedestrians in advance. The ramp forms the inflection point of the light-dark cutoff line. The inflection point is located on the left edge of the light spot and is the key dividing line between the safety lighting zone (right side) and the glare control zone (left side).

[0032] It is understandable that the connection between the left and right baffles does not necessarily have to be an inclined plate; it can also be other shapes, such as a convex plate structure, as long as it can form an inflection point.

[0033] The low beam broadening module 20 includes a second light source 21, a second light-concentrating element 22 and a first focal line lens 23 located on the light output path of the second light source 21.

[0034] like Figure 4 As shown, the first focal lens 23 broadens the light in only one direction (such as the horizontal direction) to form a linear light spot. The second light source 21 is collimated by the second focusing element 22 and the first focal lens 23 broadens the beam in a specific direction (such as the horizontal direction) to supplement the low beam width, expand the illumination range on both sides of the lane, and improve the field of vision.

[0035] The high beam widening module 30 includes a third light source 31, a third light-concentrating element 32 and a second focal line lens 33 located on the light output path of the third light source 31. like Figure 5 As shown, the second focal lens 33 functions similarly to the first focal lens 23, broadening the light in only one direction (such as the horizontal direction) to form a linear light spot. The third light source 31 is collimated by the third focusing element 32, and the second focal lens 33 performs secondary shaping or broadening of the beam in a specific direction (such as the horizontal direction), that is, supplementing the width of the high beam. In conjunction with the high beam converging module 40, it forms a wider and more uniform high beam spot.

[0036] The high beam converging module 40 includes a fourth light source 41, a fourth light-concentrating element 42 and a second focal lens 43 located on the light output path of the fourth light source 41.

[0037] like Figure 6 As shown, the second focal lens 43 can use the refraction effect of the convex lens to focus the light emitted by the light source to a point, forming a high-energy-density light spot. The fourth light source 41 is collimated by the fourth light-concentrating element 42, and the light is focused into a high-intensity small light spot by the second focal lens 43, providing a core focusing area for far-beam illumination and realizing long-distance lighting.

[0038] In low beam mode, the low beam cutoff module 10 produces a base beam pattern with a clear cutoff line, while the low beam broadening module 20 broadens the light in the horizontal direction through its focal line lens. The two are superimposed to form a uniform, wide and non-glaring low beam pattern.

[0039] In high beam mode, the high beam convergence module 40 provides central focusing light to form a powerful long-distance illumination capability; the high beam widening module 30 supplements the illumination range on both sides of the high beam through its focal line lens, making the high beam spot more uniform and the field of view wider.

[0040] The first focal lens 14, the first focal line lens 23, the second focal line lens 33 and the second focal lens 43 are an integral structure and form an outer lens 100. The light-emitting surface 100b of the outer lens 100 participates in the construction of the appearance surface of the dual-light module 1, and the light-emitting surface 100b is smooth.

[0041] That is, the four independent light source modules can work simultaneously or in shifts, which fundamentally achieves the superposition of total luminous flux, easily meeting the illumination requirements of high-end models, without the need to stack multiple independent modules. In addition, all optical functions are unified into the light-emitting surface 100b of a smooth outer lens 100. This light-emitting surface 100b directly constitutes the appearance of the headlight, achieving a truly flat and integrated shape, improving aesthetics and design freedom.

[0042] On the other hand, through precision injection molding, the first focal lens 14, the first focal line lens 23, the second focal line lens 33, and the second focal lens 43 are integrated on the same optical substrate. There are no physical seams between the first focal lens 14, the first focal line lens 23, the second focal line lens 33, and the second focal lens 43. When light passes through, there will be no stray light caused by scattering at the seams, and there will be no light-dark discontinuity, thus ensuring light efficiency.

[0043] In one embodiment of this application, please refer to Figures 7 to 9 As shown, the low beam cutoff module 10, the low beam widening module 20, the high beam widening module 30, and the high beam converging module 40 are distributed along the first direction X; The four light source modules are arranged along the first direction X, that is, along the horizontal direction. Each module corresponds to a specific horizontal area of ​​the road surface. The light propagates in the horizontal partition, without the light path overlap caused by vertical stacking. This reduces the light crosstalk problem of traditional multi-module modules from the root and ensures the purity of the light pattern.

[0044] It's also important to understand that in this technology, the low beam and high beam modules are positioned vertically, with the low beam reflector / concentrator baffle on top and the high beam reflector / concentrator below. The light from the upper and lower reflectors is divided and separated by the baffle (high and low beam cutoff plate), forming the low beam, the low beam cutoff line, and the high beam. Because the high and low beams are cut off by the baffle, when both are illuminated simultaneously, a dark gap appears on the road surface, creating a visually abrupt change while driving.

[0045] In this embodiment, because the low beam cutoff module 10, low beam widening module 20, high beam widening module 30 and high beam converging module 40 are distributed along the first direction X, the cutoff structure 13 cannot simultaneously block both low and high beams. That is, the low beam cutoff module 10, low beam widening module 20, high beam widening module 30 and high beam converging module 40 distributed along the first direction X each have an independent optical path. The light spots of low beam and high beam only overlap and do not conflict in the first direction X, and will not form a dark slit due to competition for the optical path.

[0046] Please continue reading. Figure 9 The first focusing element 12, the cutoff line structure 13, and the first focal lens 14 are distributed along the second direction Y; Correspondingly, the second condenser 22 and the first focal lens 23 are distributed along the second direction Y; the third condenser 32 and the second focal lens 33 are distributed along the second direction Y; and the fourth condenser 42 and the second focal lens 43 are distributed along the second direction Y. In this way, the component distribution in each module can realize complex optical functions within a limited depth, which is conducive to the miniaturization and flattening of the module.

[0047] The light-emitting surface 100b is a convex cylindrical surface that extends along the first direction X and bends in the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0048] A column that bends in the Z-direction has a certain light-focusing effect, where the Z-direction is the height direction of the vehicle.

[0049] Based on the embodiments of this application, the low beam cutoff module 10, the low beam widening module 20, the high beam widening module 30, and the high beam converging module 40 are distributed along the first direction X and extend along the first direction X with the light-emitting surface 100b. The first direction X is the direction of the width of the vehicle. In this way, the entire dual-beam module 1 can be more suitable for the narrow opening design of the vehicle. The narrow opening design can make the vehicle's headlights more compact, improve the vehicle's recognition and sense of technology, and adapt to the overall design trend of the front face of the car.

[0050] It is understandable that the distribution of the low beam cut-off module 10, the low beam widening module 20, the high beam widening module 30, and the high beam converging module 40 along the first direction X can have multiple layouts, that is, the low beam cut-off module 10, the low beam widening module 20, the high beam widening module 30, and the high beam converging module 40 can have multiple arrangements and combinations.

[0051] In this embodiment, the low beam cutoff module 10, low beam widening module 20, high beam widening module 30, and high beam converging module 40 are preferably distributed sequentially along the first direction X. This arrangement ensures that the optical axes of the low beam cutoff module and low beam widening module 20 are closer to the ground, while the optical axes of the high beam widening module 30 and high beam converging module 40 are straighter (closer to horizontal). When distributed sequentially, the light patterns emitted by the cutoff module and low beam widening module 20 are in front (closer to the vehicle), while the light patterns emitted by the high beam widening module 30 and high beam converging module 40 are behind (projecting towards a distance). This prevents the low-angle light from the low beam from interfering with the straight light of the high beam, reducing the possibility of stray light and dark spots.

[0052] Following on the above, the following will combine... Figure 9 as well as Figure 10 The first focal lens 14, the second focal lens 43, the first focal line lens 23, and the second focal line lens 33 are further described.

[0053] The first focal lens 14 includes a first light-incident surface 141, which is a convex cylindrical surface bent in the first direction X. The first focal lens 14 also has a first light-exiting surface 142, which is constructed as the light-exiting surface 100b of the outer lens 100. Therefore, the first light-exiting surface 142 is a convex cylindrical surface bent in the third direction Z. That is, the two optical surfaces of the first focal lens 14 are convex cylindrical surfaces in the perpendicular direction, so that the light emitted by the first light source 11 can be refracted by the first light-incident surface 141 and the second light-exiting surface 232, thereby focusing the light beam and forming a near-light core region.

[0054] Similarly, the second focal lens 43 includes a fourth light-incident surface 431 and a fourth light-exiting surface 432. The fourth light-incident surface 431 is a convex cylindrical surface that bends in the first direction X, and the fourth light-exiting surface 432 is a convex cylindrical surface that bends in the third direction Z. This allows the light emitted by the fourth light source 41 to be refracted by the fourth light-incident surface 431 and the fourth light-exiting surface 432, thereby focusing the light beam and forming the high beam core region.

[0055] The first focal lens 23 includes a second light-incident surface 231 and a second light-exiting surface 232. The second light-incident surface 231 is a plane perpendicular to the second direction Y, and the second light-exiting surface 232 is a convex cylindrical surface that bends in the third direction Z. Since only the second light-exiting surface 232 is set as a convex cylindrical surface, the light emitted by the second light source 21 is refracted and focused by the second light-exiting surface 232 to form a near beam that is broadened in the first direction X, thus ensuring the light efficiency of the near beam.

[0056] In the first focal lens 23, the light emitted by the second light source 21 can enter the first focal lens 23 perpendicularly, avoiding light loss due to refraction when the light enters. At this time, the lateral expansion of the light is completely achieved by the second light-exiting surface 232 of the first focal lens 23. The second light-incoming surface 231 only plays a stable light-guiding role, ensuring that more light can be used by the second light-exiting surface 232 for lateral expansion.

[0057] Similarly, the second focal lens 33 includes a third light-incident surface 331 and a third light-exiting surface 332. The third light-incident surface 331 is a plane perpendicular to the second direction Y, and the third light-exiting surface 332 is a convex cylindrical surface that bends in the third direction Z. Since only the third light-exiting surface 332 is set as a convex cylindrical surface, the light emitted by the third light source 31 is refracted and focused by the third light-exiting surface 332 to form a widened high beam in the first direction X, thus ensuring the light efficiency of the high beam output.

[0058] In the second focal lens 33, the light emitted by the third light source 31 can enter the second focal lens 33 perpendicularly, avoiding light loss caused by refraction when the light enters. The lateral widening of the light is completed by the third light-exiting surface of the second focal lens 33. The third light-incoming surface does not change the direction of the light, ensuring that the lateral coverage of the high beam is accurate, forming a high beam spot that is strong in the middle and wide on both sides with the lateral narrow beam of the high beam, without overlapping interference.

[0059] Furthermore, such as Figure 9 and Figure 10 As shown, the second light-incident surface 231 and the third light-incident surface 331 are coplanar. The coplanar design ensures that the initial conditions when light enters the outer lens 100 from the near beam broadening module 20 and the far beam broadening module 30 are consistent, which helps to reduce unnecessary optical deviations and ensures that a uniform and accurate light spot can be formed when the light exits the outer lens 100.

[0060] It is understandable that complex or discontinuous optical interfaces are prone to generating unintended stray light, while the coplanarity of the second light-incident surface 231 and the third light-incident surface 331 helps to guide the light to propagate more orderly, thereby reducing the generation of stray light and improving light efficiency and imaging quality.

[0061] Furthermore, it is understandable that integrating the second light-incident surface 231 and the third light-incident surface 331 into a continuous plane reduces the number and complexity of optical interfaces. From the perspective of injection molding, a continuous flat surface makes the cavity structure of the mold very simple, which can effectively shorten the mold development cycle and reduce manufacturing difficulty and cost.

[0062] It is understood that the first focusing element 12, the second focusing element 22, the third focusing element 32, and the fourth focusing element 42 can all be focusing elements, or they can be reflecting bowls (reflecting bowls), or some can be focusing elements and some can be reflecting bowls. The specific components that are reflecting bowls and which are focusing elements are not limited here. In the embodiments of this application, at least one of the first focusing element 12, the second focusing element 22, the third focusing element 32, and the fourth focusing element 42 is a reflecting bowl.

[0063] In one embodiment of this application, the first focusing element 12, the second focusing element 22, the third focusing element 32 and the fourth focusing element 42 may all be reflective bowls. The reflective bowls achieve light reflection through high reflectivity coatings such as aluminum film and silver film. The light can be focused with only one reflection, reducing the light loss rate and ensuring the light output efficiency.

[0064] In one embodiment, please refer to Figure 7 as well as Figure 8 The first focusing element 12 and the second focusing element 22 are integrated into one structure, and the third focusing element 32 and the fourth focusing element 42 are integrated into one structure.

[0065] The first condenser 12 and the second condenser 22 are integrated into a single structure, providing a relatively stable mounting reference for the first light source 11, the second light source 21, and the corresponding first focal lens 14 and the first focal line lens 23. The third condenser 32 and the fourth condenser 42 are integrated into a single structure, providing a relatively stable mounting reference for the third light source 31, the fourth light source 41, and the corresponding second focal lens 43 and the second focal line lens 33.

[0066] In the optical path system, the low beam cutoff module 10 and the low beam widening module 20 need to be superimposed to form a complete low beam shape, and the high beam converging module 40 and the high beam widening module 30 need to form a complete high beam shape. The first focusing element 12 and the second focusing element 22 are integrated into one unit, and the third focusing element 32 and the fourth focusing element 42 are integrated into one unit. This is equivalent to setting the relative positions of the low beam optical path and the high beam optical path in terms of physical structure. This ensures that the core lighting area and the widening area of ​​the low beam, and the center lighting area and the surrounding wide area of ​​the high beam can be seamlessly and uniformly connected and superimposed, effectively avoiding the phenomenon of dark areas or uneven brightness, and significantly improving the lighting quality.

[0067] In addition, the integrated structure can reduce the number of molds, thereby effectively shortening the mold development cycle and reducing manufacturing difficulty and cost.

[0068] Furthermore, please refer to Figures 3 to 6 In one embodiment of this application, the dual-light module 1 further includes a first circuit board 61, a second circuit board 62, a third circuit board 63 and a fourth circuit board 64, and the first light source 11, the second light source 21, the third light source 31 and the fourth light source 41 are respectively disposed on the first circuit board 61, the second circuit board 62, the third circuit board 63 and the fourth circuit board 64. The dual-light module 1 also includes a first heat dissipation component 71 and a second heat dissipation component 72. The first circuit board 61 and the second circuit board 62 are disposed on the first heat dissipation component 71, and the first heat dissipation component 71, the third light-concentrating element 32 and the fourth light-concentrating element 42 are an integral structure. The third circuit board 63 and the fourth circuit board 64 are disposed on the second heat dissipation component 72, and the second heat dissipation component 72, the first light-concentrating element 12, and the second light-concentrating element 22 are integrally structured.

[0069] The first circuit board 61, the second circuit board 62, the third circuit board 63, and the fourth circuit board 64 are the basic carriers for driving and controlling the corresponding first light source 11, second light source 21, third light source 31, and fourth light source 41, ensuring the reliable operation of each light source and supporting the overall performance of the dual-light module 1.

[0070] The four light sources are located on four separate circuit boards, which means that each light source can be powered and its power can be adjusted independently, enabling more precise control of the light pattern.

[0071] It should be understood that, in the embodiments of this application, the first heat dissipation component 71 and the second heat dissipation component 72 are heat dissipation structures with multiple heat dissipation plate arrays. By setting the first heat dissipation component 71 and the second heat dissipation component 72, the heat on the first circuit board 61, the second circuit board 62, the third circuit board 63 and the fourth circuit board 64 can be effectively reduced, ensuring the stability of the light source and improving the service life of the entire dual-light module 1.

[0072] In the embodiments of this application, the first heat dissipation component 71 is integrated with the third light-concentrating component 32 and the fourth light-concentrating component 42, and the second heat dissipation component 72 is integrated with the first light-concentrating component 12 and the second light-concentrating component 22. This means that the first light-concentrating component 12, the second light-concentrating component 22, the third light-concentrating component 32 and the fourth light-concentrating component 42 themselves also become part of the heat dissipation, increasing the effective heat dissipation area and heat capacity.

[0073] In addition, the integrated structure can reduce the number of molds, thereby effectively shortening the mold development cycle and reducing manufacturing difficulty and cost.

[0074] In one embodiment of this application, please refer back to the previous section. Figure 1 as well as Figure 2The dual-beam module 1 also includes a lens bracket 50, which forms a mounting cavity 50a and a mounting port 50b communicating with the mounting cavity 50a. The low beam cutoff module 10, the low beam broadening module 20, the high beam broadening module 30 and the high beam converging module 40 are all installed in the mounting cavity 50a. The outer lens 100 is installed in the mounting port 50b, and the light-inlet surface of the outer lens 100 is located inside the mounting cavity 50a, while the light-outlet surface of the outer lens 100 is located outside the mounting cavity 50a.

[0075] That is, the near beam cutoff module 10, the near beam broadening module 20, the far beam broadening module 30 and the far beam converging module 40 are integrated into the same mounting cavity 50a through a lens bracket 50, providing a common mounting reference for the optical components of each module. The lens bracket 50 includes two sub-brackets. When installing the dual-beam module 1, the two sub-brackets are in a separate state, which makes it easy for the user to assemble the dual-beam module 1. Finally, the outer lens 100 is encapsulated.

[0076] The integrated outer lens 100 is mounted in the mounting port 50b, and its light-emitting surface constitutes the appearance of the headlight, making the headlight look simple and high-end. At the same time, the mounting cavity 50a and the outer lens 100 together form a relatively sealed unit, which can effectively prevent dust and moisture, protect the internal precision optical components and light source, and improve the long-term reliability of the entire dual-beam module 1 in complex operating environments.

[0077] This application also provides a vehicle light, which includes a bi-beam module 1 and a dimming mechanism (not shown in the figure) as described in this application. The dimming mechanism is driven and connected to the bi-beam module 1. In a specific embodiment of this application, the dimming mechanism is connected to the lens bracket 50.

[0078] In this way, only one dimming mechanism needs to be connected to the lens bracket 50. There is no need for multiple dimming mechanisms to drive different modules. That is, the dimming mechanism acts as the only actuator, pushing or pulling the lens bracket 50. The bracket drives all the optical modules on it to rotate synchronously around the preset fulcrum as a whole unit. This allows multiple lighting modules to be controlled simultaneously with one action, simplifying the system structure.

[0079] The rotation of the lens bracket 50 causes the integrated low beam cut-off module 10, low beam widening module 20, high beam widening module 30 and high beam converging module 40 to change their pitch angles simultaneously, thereby achieving overall beam height adjustment and ensuring that the illumination distance is always kept within the optimal range.

[0080] Based on a set of dimming mechanisms, the high synchronization of all light patterns, such as low beam and high beam, can be ensured. The relative positions of the light patterns are fixed, avoiding light distortion caused by the asynchrony of multiple dimming mechanisms. In addition, it reduces moving parts and connection points, lowers the potential failure rate, and helps to ensure the accuracy of light patterns and long-term stability.

[0081] In addition, the layout of the single dimming mechanism and lens bracket 50 is more compact, which is conducive to the lightweight design of the headlights and also reduces costs.

[0082] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
