[0070] The specific embodiments of this disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation, and the scope of protection of this disclosure is not limited to the specific embodiments described below.

[0071] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "setup" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0072] Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as “first,” “second,” or “third” may explicitly or implicitly include one or more of the stated features.

[0073] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," "right," "front," and "rear" generally refer to the positional relationship of the vehicle lights during actual use. For example, when the vehicle lights are located at the rear of the vehicle and emit light towards the rear, the direction the front of the vehicle points is rear, and the direction the rear of the vehicle points is front. "Up," "down," "left," and "right" are positional relationships determined based on the positional relationships of "front" and "rear." Specifically, in the accompanying drawings provided in this disclosure, the orientations or positional relationships used are based on the orientations or positional relationships shown in the drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. The directional terms in this disclosure should be understood in conjunction with the actual installation state.

[0074] Referring to Figures 1 to 9, a first aspect of this disclosure provides a lighting device including a mounting mechanism 1, a first module 2, and a second module 3. Both the first module 2 and the second module 3 are mounted on the mounting mechanism 1. As shown in Figures 4 to 6, the first module 2 can form a first functional light pattern a and an auxiliary light pattern b. The second module 3 can form an adaptive light pattern c. The auxiliary light pattern b and the adaptive light pattern c are superimposed to form a second functional light pattern. This disclosure simplifies the number of components and reduces costs by jointly mounting the first module 2 and the second module 3 on the same mounting mechanism 1. Furthermore, since the auxiliary light pattern b and the adaptive light pattern c are superimposed to realize the second functional light pattern, integrating modules that realize multiple functional light patterns onto the same mounting mechanism 1 reduces the space occupied by the lighting device.

[0075] As we can understand, "Adaptive Beam Type C" is an automotive lighting system that can automatically change the operating mode of the front lighting system and adjust the beam pattern based on weather conditions, external light, road conditions, and driving information. "Adaptive Beam Type C" can eliminate dark areas in the field of vision at night or in low visibility, providing a wider and more reliable lighting field of vision, avoiding glare, and ensuring the safety of drivers and pedestrians. The working principle of Adaptive Beam Type C is to collect dynamic signal parameters of the vehicle itself and surrounding road users through various sensors installed on the vehicle (such as vehicle speed, attitude, turning angle, position sensors, lidar, millimeter-wave radar, etc.). These parameters are then analyzed and processed by the control unit using algorithms to generate control signals that control the beam pattern of the corresponding lighting modules.

[0076] In some embodiments, as shown in Figures 4 to 8, the first functional beam pattern a can be a low beam pattern, the auxiliary beam pattern b can be an auxiliary high beam pattern, and the adaptive beam pattern c can be an adaptive main high beam pattern. Specifically, the first functional beam pattern a, as a low beam pattern, provides low beam illumination for the vehicle. The auxiliary beam pattern b, as an auxiliary high beam pattern, provides widening for the adaptive high beam pattern. The adaptive beam pattern c, as an adaptive main high beam pattern, adaptively adjusts the beam pattern according to weather conditions, external light, road conditions, and driving information.

[0077] Among them, the types of the first functional beam type a and the auxiliary beam type b are not limited to the low beam type and auxiliary high beam type in the above technical solutions, but can also be beam types with other functions.

[0078] It should be noted that when adaptive high beam lighting is needed, the driver can choose to activate this function, using only the second module 3 in the lighting device to achieve adaptive high beam. When adaptive high beam lighting is not needed, the driver can choose to deactivate this function, using both the first module 2 and the second module 3 to achieve high beam, and the first module 2 to achieve low beam.

[0079] In some embodiments, as shown in Figures 1, 28 to 30, the first module 2 and the second module 3 can be aligned or staggered in the vertical direction, or aligned or staggered in the horizontal direction. It is understood that "vertical direction" refers to the height direction of the vehicle, and "horizontal direction" refers to the length direction of the vehicle.

[0080] It should be noted that, as shown in Figures 28 to 30, the orientation (vertical, forward, backward, or left / right) can be adjusted according to the specific usage environment. Once the positional relationship between the two modules is set according to the actual situation, installation can be achieved simply by adjusting the structure of mounting mechanism 1. Installation is convenient, quick, and widely applicable. It is understood that "forward," "backward," "left," "right," "up," and "down" here can be based on the vehicle.

[0081] Referring to Figures 10 to 12, in a specific embodiment of this disclosure, the first module 2 includes: at least one first light source 251, at least one second light source 252, a first primary optical component 24, and a first secondary optical component 21. The first beam emitted from the first light source 251 is converged by the first primary optical component 24 and then projected by the first secondary optical component 21 to form a near-beam pattern. The second beam emitted from the second light source 252 is converged by the first primary optical component 24 and then projected by the first secondary optical component 21 to form an auxiliary far-beam pattern.

[0082] It should be noted that, as some specific embodiments of the first primary optical component 24 in this disclosure, the first primary optical component 24 can be a first focusing component and / or a first reflecting component. When the first primary optical component 24 is a first focusing component, it can converge the light beam emitted from the first light source 251 or the second light source 252 before propagation, avoiding stray light and improving light utilization. When the first primary optical component 24 is a first reflecting component, it can reflect the light beam emitted from the first light source 251 or the second light source 252 before propagation, changing the light emission direction and making the light source placement more flexible, saving installation space. When the first primary optical component 24 is both a first focusing component and a first reflecting component, it can reflect and converge the light beams emitted from the first light source 251 and the second light source 252 respectively before propagation, avoiding stray light while ensuring effective light propagation and flexibly setting the positions of various components.

[0083] In some specific embodiments, the first focusing component includes a first functional focusing unit 241 and an auxiliary focusing unit 242. The first functional focusing unit 241 is configured correspondingly to the first light source 251, and the auxiliary focusing unit 242 is configured correspondingly to the second light source 252.

[0084] As shown in Figures 13 and 32, as a specific embodiment of the first functional concentrator 241, the first functional concentrator 241 can be a low-beam concentrator. The light-emitting surface of this low-beam concentrator includes a first low-beam emitting surface 241a and a second low-beam emitting surface 241b. The second low-beam emitting surface 241b is disposed on both sides of the first low-beam emitting surface 241a. Several low-beam stripe patterns 241c are provided on both the first low-beam emitting surface 241a and the second low-beam emitting surface 241b. The stripe patterns extend along the width direction of the emitting surface and are distributed along the length direction of the emitting surface. Further, the spacing between two adjacent low-beam stripe patterns 241c on the first low-beam emitting surface 241a can be greater than the spacing between two adjacent low-beam stripe patterns 241c on the second low-beam emitting surface 241b. Providing several patterns allows for more uniform light projection, and the superposition and transition of light patterns are more uniform and smooth. Since the spacing between two adjacent low beam stripes 241c on the first low beam emitting surface 241a is greater than the spacing between two adjacent low beam stripes 241c on the second low beam emitting surface 241b, it can ensure both the brightness of the low beam pattern and the illumination range of the low beam pattern, thus improving the lighting effect.

[0085] As shown in Figures 13 and 32, in one specific embodiment of the auxiliary concentrator 242, the auxiliary concentrator 242 can be a high-beam concentrator. The high-beam emitting surface of this high-beam concentrator includes a first high-beam emitting surface 242a and a second high-beam emitting surface 242b. The second high-beam emitting surface 242b is disposed twice on the first high-beam emitting surface 242a. Furthermore, the first high-beam emitting surface 242a has a smooth surface. A plurality of high-beam stripe patterns 242c are provided on the second high-beam emitting surface 242b. The high-beam stripe patterns 242c extend along the width direction of the emitting surface and are distributed along the length direction of the emitting surface. The spacing between two adjacent high-beam stripe patterns 242c gradually increases from the direction towards the first high-beam emitting surface 242a to the direction away from the first high-beam emitting surface 242a. Furthermore, an angle can be formed between the first high-beam emitting surface 242a and the second high-beam emitting surface 242b, with the opening of the angle facing the light-incident end. Increasing the spacing of the high-beam stripe pattern 242c facilitates the outward extension of the high-beam pattern generated after the light emitted from the second high-beam emitting surface 242b is projected, resulting in a larger extension angle. This also helps to ensure more uniform and smoother transitions in the superposition of high-beam pixels. The first high-beam emitting surface 242a uses a smooth surface to ensure the brightness value of the auxiliary high-beam center pattern. It can be understood that, as shown in Figure 32, "width direction" refers to the vertical direction in the figure, and "length direction" refers to the horizontal direction in the figure.

[0086] Specifically, referring to Figures 13 and 32, in a preferred embodiment of the auxiliary concentrator 242 used in the lighting device of this disclosure, when the auxiliary concentrator 242 is a high-beam concentrator, the high-beam emitting surface of the high-beam concentrator includes a first high-beam emitting surface 242a and four second high-beam emitting surfaces 242b. The first high-beam emitting surface 242a is located in the central region, and two second high-beam emitting surfaces 242b are sequentially arranged on both sides of the first high-beam emitting surface 242a along the length of the concentrator's emitting surface. High-beam stripe patterns 242c are formed on the second high-beam emitting surfaces 242b. A plane is formed in the light emission direction and the arrangement direction of the high-beam emitting surfaces, and the cross-sections of the first high-beam emitting surfaces 242a and the second high-beam emitting surfaces 242b on this plane form an angle. The cross-sections of the first high-beam emitting surface 242a and the plurality of second high-beam emitting surfaces 242b on this plane form a convex shape. Two adjacent second high-beam emitting surfaces 242b form an angle at their cross-sections on the plane. The further away the second high-beam emitting surface 242b is from the first high-beam emitting surface 242a, the smaller its slope. By changing the size of the angle, the overlapping area of ​​the sub-illumination patterns formed by each second high-beam emitting surface 242b can be changed, making the transition between adjacent sub-illumination patterns more uniform and smoother. The high-beam stripe pattern 242c can be several structures with concave cross-sectional profiles. Each high-beam stripe pattern 242c extends along the width direction of the condenser emitting surface. Several high-beam stripe patterns 242c are distributed along the length direction of the condenser emitting surface. The spacing between two adjacent high-beam stripe patterns 242c on each second high-beam emitting surface 242b gradually increases towards the direction away from the first high-beam emitting surface 242a. The spacing between adjacent second far-beam emitting surfaces 242b gradually increases towards the direction away from the first far-beam emitting surface 242a. Specifically, this spacing can be increased from 0.79 mm to 1.16 mm. The far-beam stripe pattern 242c on the second far-beam emitting surfaces 242b allows for a larger extension angle of the sub-illumination patterns formed by each second far-beam emitting surface 242b, ensuring the illumination range of the concentrator. The first far-beam emitting surface 242a is preferably a planar emitting surface, which ensures the illumination intensity of the illumination pattern formed by the first emitting surface. Specifically, the first far-beam emitting surface 242a, the second far-beam emitting surface 242b, and the pattern structure are integrally formed, ensuring the structural stability of the far-beam emitting surface and saving on the production cost of the concentrator emitting surface.

[0087] Figure 18 shows the sub-illumination pattern formed by the first far-beam emitting surface 242a, which ensures the illumination intensity of the final illumination pattern formed by the concentrator. Figure 14 shows the sub-illumination pattern formed by the second far-beam emitting surface 242b, located near and to the right of the first far-beam emitting surface 242a. Figure 16 shows the sub-illumination pattern formed by the second far-beam emitting surface 242b, located near and to the left of the first far-beam emitting surface 242a. Figure 15 shows the sub-illumination pattern formed by the second far-beam emitting surface 242b, located away from and to the right of the first far-beam emitting surface 242a. Figure 17 shows the sub-illumination pattern formed by the second far-beam emitting surface 242b, located away from and to the left of the first far-beam emitting surface 242a. As can be seen from Figures 14 to 16, as the distance between two connected high-beam stripe patterns 242c gradually increases in the direction away from the first high-beam emitting surface 242a, the expansion angle of the formed sub-illumination pattern also increases, and the illumination range increases accordingly. As shown in Figure 19, as a specific embodiment of this disclosure, the light pattern is the final auxiliary high-beam illumination pattern formed by the combination of the sub-illumination patterns formed by the above-mentioned emitting surfaces. This auxiliary high-beam illumination pattern has strong light intensity and a large illumination range, and the superposition between the light patterns is more uniform and the transition is smoother.

[0088] Furthermore, for ease of installation and structural stability, the first functional condenser 241 and the auxiliary condenser 242 can be integrally molded components, and can be installed using a bracket. Additionally, the bracket and the first primary optical component 24 can also be integrally molded components.

[0089] It is understood that, according to the above specific implementation, the first module 2 can be an integrated high and low beam module, providing the lighting device with auxiliary high beam and low beam lighting functions.

[0090] As some specific embodiments of this disclosure, referring to Figures 23 and 24, the second module 3 in the lighting device provided by this disclosure includes multiple third light sources 351 and a second-stage optical component 31. The third beam emitted from the third light sources 351 is projected by the second-stage optical component 31 to form an adaptive light pattern c. Since the adaptive light pattern c is formed by selectively emitting light from multiple third light sources 351, multiple third light sources 351 are provided to project multiple beams.

[0091] Furthermore, the second module 3 also includes a second primary optical component 33, which includes multiple light guide units 332. At least some of the light guide units 332 have their light-incident portions spaced apart, and the light-exiting surfaces of the multiple light guide units 332 are connected to form the light-exiting surface of the second primary optical component 33. The third beam emitted from the third light source 351 is converged by the second primary optical component 33 and then projected by the second secondary optical component 31 to form an adaptive light pattern c. The light guide units 332 can converge the optics emitted from the third light source 351. The multiple light guide units 332 are also provided to cooperate with multiple third light sources 351, enabling the convergence of the beams emitted by each third light source 351 and enhancing the lighting effect.

[0092] Further, as shown in Figures 23 and 24, the second-stage optical component 31 includes an outer lens 311 and an inner lens 32. The third beam emitted from the third light source 351 is converged by the second primary optical component 33, propagated through the inner lens 312, and then projected by the outer lens 311 to form an adaptive light pattern c. The outer lens 311 and the inner lens 312 can jointly image the light-emitting surface of the second primary optical component 33.

[0093] Specifically, as shown in Figure 9, in a preferred embodiment of the second primary optical component 33, the second primary optical component can be mounted via a heat sink 334. In addition to multiple light guide units 332, the second primary optical component 33 may also include a concentrator plate 331 and a concentrator bracket 333. The multiple light guide units 332, spaced apart, can be integrally molded. The multiple light guide units 332 are fixed to the concentrator bracket 333 via the concentrator plate 331. The optical component composed of the multiple light guide units 332 can converge light. The concentrator bracket 333 can be mounted on the heat sink 334. The heat sink 334 can dissipate heat for the multiple light guide units 332. The multiple light guide units 332 are preferably silicone concentrators, with multiple spaced light guides formed on the silicone to converge the light emitted from the third light source 351.

[0094] Understandably, a concentrator needs to be able to efficiently focus light onto a small area, increasing light intensity. It also needs to be heat-resistant, able to withstand exposure to high-intensity light sources without damage. Furthermore, it needs optical transparency to ensure effective light transmission. Silicone material remains stable at high temperatures, without deforming or losing elasticity, which helps maintain its shape and function in high-temperature applications with high-intensity light sources. Simultaneously, silicone is corrosion-resistant, resisting the erosion of acids, alkalis, and other chemicals, making it suitable for use in various harsh environments. It also has good waterproof properties, effectively preventing moisture penetration and improving the waterproofness of the lighting device. Therefore, silicone concentrators have the advantages of high temperature resistance, corrosion resistance, and good waterproofness, extending the service life of lighting devices.

[0095] As shown in Figure 25, in order to install multiple light guide units 332 well, this disclosure uses a condenser pressure plate 331 and a condenser bracket 333 for installation. The condenser pressure plate 331 is provided with protruding structures or groove structures that match the multiple spaced light guide units 332 so that the second far-beam condenser 332 can be well installed on the condenser bracket 333. Using the condenser bracket 333 to install several light guide units 332 can also ensure the stability of the installation.

[0096] In addition, the optical component that forms the adaptive light type c can also be a matrix light source component composed of multiple LED light sources and a lens component composed of lenses corresponding to each LED light source.

[0097] Furthermore, the first module 2 also includes a first mounting plate 25, and the second module 3 also includes a second mounting plate 35. The lighting device provided in this disclosure also includes a dimming bracket 34. The second mounting plate 35 is adjustablely connected to the mounting mechanism 1 via the dimming bracket 34, which is used to adjust the relative position of the third light source 351 and the second-stage optical component 31. Alternatively, the first mounting plate 25 is adjustablely connected to the mounting mechanism 1 via the dimming bracket 34, which is used to adjust the relative position of the first light source 251 and the second light source 252 with the first-stage optical component 21.

[0098] It should be noted that the first light source 251 and the second light source 252 are both mounted on the first mounting plate 25, and the third light source 351 is mounted on the second mounting plate 35. The main function of the dimming bracket 34 is to adjust the direction and angle of the light to precisely adjust the relative position of the light patterns of the first module 2 and the second module 3. The first mounting plate 25 and the second mounting plate 35 can be circuit boards, and the first mounting plate 25 can be used to mount other components in the first module 2, such as the first primary optical component 24. Similarly, the second mounting plate 35 can be used to mount other components in the second module 3, such as the second primary optical component 33.

[0099] It should also be noted that, during specific installation, as shown in Figure 23, as a specific embodiment of the dimming bracket 34, the dimming bracket 34 can be used to adjust the relative position between the third light source 351 and the second-stage optical component 31, that is, between the third light source 351 and the inner lens 312 or the outer lens 311. Depending on the application, the dimming bracket 34 can also serve as an adjustment element capable of adjusting the relative position between the first light source 251 and the second light source 252 and the first-stage optical component 21.

[0100] Specifically, as shown in Figure 23, as a specific embodiment of the dimming bracket 34 in this disclosure, taking the dimming bracket 34 for adjusting the relative position between the third light source 351 and the second-stage optical component 31 as an example, the dimming bracket 34 is adjustablely connected to the mounting mechanism 1 through the first dimming structure, and the dimming bracket 34 is adjustablely connected to the second mounting plate 35 through the second dimming structure.

[0101] Specifically, as shown in Figures 24 and 31, the first dimming structure includes a first dimming hole 341 and a first connecting hole 344 formed on the mounting mechanism 1 and the dimming bracket 34, respectively. The first dimming element passes through the first dimming hole 341 to be fixed to the first connecting hole 344. The aperture of the first dimming hole 341 in a first direction is larger than the aperture of the first connecting hole 344, so that the dimming bracket 34 can move relative to the mounting mechanism 1 in a first direction parallel to the optical axis of the second module 3.

[0102] Specifically, as shown in Figure 31, in one specific embodiment, the first dimming hole 341 can be an oblong hole disposed on the mounting mechanism 1, and the first connecting hole 344 can be a threaded hole disposed on the dimming bracket 34. The first dimming component can be a bolt, which passes through the oblong hole and the threaded hole. The dimming bracket 34 moves along the first direction, causing the bolt to move within the longer diameter range of the oblong hole, so as to adjust the relative distance between the dimming bracket 34 and the third light source 351 in the first direction. When it moves to the desired position, the bolt is tightened to fix the dimming bracket 34 and the mounting mechanism 1.

[0103] It is understandable that "first direction" refers to the direction along the front and rear of the vehicle, that is, the optical axis direction of the outer lens 311.

[0104] Furthermore, as shown in Figure 24, a dimming protrusion 342 can be provided on the dimming bracket 34 for the first dimming hole 341 or the first connecting hole 344 to be positioned, and a guide groove 343 can be provided on the mounting mechanism 1. The cross-sectional shape of the guide groove 343 is adapted to the cross-sectional shape of the dimming protrusion 342, thereby achieving a match between the dimming protrusion 342 and the guide groove 343. The guide groove 343 can guide the dimming bracket 34 during position adjustment, making the front and rear dimming movements more stable and precise. It should be noted that "front" and "rear" here refer to the front and rear of the vehicle, and also to the optical axis direction of the second module 3 and the first direction.

[0105] It should also be noted that, as shown in Figure 24, the guide groove 343 can be set on both sides of the mounting mechanism 1, or it can be set at the bottom or top. It is only necessary to set a matching dimming protrusion 342 at the corresponding position of the dimming bracket 34.

[0106] Referring to Figures 26 and 27, as a specific embodiment of the second dimming structure in this disclosure, the second dimming structure includes a second dimming hole 345 and a second connecting hole 347 respectively formed on the dimming bracket 34 and the second mounting plate 35. A second adjusting member 346 passes through the second dimming hole 345 to fix the second connecting hole 347. The diameter of the second dimming hole 345 is larger than the diameter of the second connecting hole 347, so that the dimming bracket 34 can move relative to the second mounting plate 35 along a second direction and / or a third direction perpendicular to the optical axis of the second module 3. It is understood that the "second direction" refers to the left-right direction on a plane perpendicular to the optical axis of the outer lens 311. The "third direction" refers to the up-down direction on a plane perpendicular to the optical axis of the outer lens 311.

[0107] Taking the second dimming hole 345 mounted on the dimming bracket 34 as an example, a second connecting hole 347 matching the second dimming hole 345 is provided on the second mounting plate 35, wherein the diameter of the second connecting hole 347 is smaller than the diameter of the second dimming hole 345. When the dimming bracket 34 moves along the second or third direction, the relative position between the second dimming hole 345 and the second connecting hole 347 also changes. This can be understood as the relative position between the center of the second dimming hole 345 and the center of the second connecting hole 347 in the second or third direction changing, but the edge of the second connecting hole 347 always remains within the range of the second dimming hole 345. When the desired position is reached, the second adjusting member 346 is fixed to the second connecting hole 347, thereby fixing the dimming bracket 34 to the second mounting plate 35 and completing the adjustment of the relative position between the dimming bracket 34 and the second mounting plate 35 in the second or third direction.

[0108] When adjustment is required, the second mounting plate 35 can be moved up, down, left, and right, thereby allowing the second connecting hole 347 to move within the allowable range of the second dimming hole 345. When the desired position is reached, the second adjusting member 346 connects the second connecting hole 347 to the second dimming hole 345, thus determining the position of the second mounting plate 35 and adjusting the relative position between the dimming bracket 34 and the second mounting plate 35. Furthermore, the relative position between the third light source 351 and the second-stage optical component 31 can be adjusted.

[0109] In some specific embodiments, the inflection point of the near-beam cutoff line in the first module 2 can be used as the dimming reference, and the relative positions of the second module 3 and the first module 2 can be fixed by adjusting the position of the second module 3. The dimming scheme is divided into two assemblies, and the parts of the two parts need to be assembled first. The former is the lens part, which includes all the parts of the first module 2 and the second primary optical component 31 of the second module 3. The latter is the remaining parts of the second module 3, including the dimming bracket 34, the first primary optical component 24, the second mounting plate 35, etc.

[0110] As shown in Figure 23, in order to avoid interference with the third beam of the third light source 351 during propagation, a through hole is provided on the dimming bracket 34 so that the second primary optical component 33 can pass through, and the propagation of the third beam will not be interfered with when the dimming function is realized.

[0111] Further, referring to Figures 2 and 9, the mounting mechanism 1 used in this disclosure includes a lens bracket 11 and a module bracket 12. The lens bracket 11 is fitted onto the end of the module bracket 12. The lens bracket 11 can be connected to the module bracket 12 via clips or bolts. The lens bracket 11 is mainly used to mount various lenses capable of projecting light patterns, such as the primary optical component 21 and the secondary optical component 31, while the module bracket 12 is used for the integrated mounting of other components. This disclosure simplifies the mounting mechanism 1 by providing a lens bracket 11 and a module bracket 12, and enables the integrated mounting of various lighting modules with different functions, improving structural stability, reducing the space occupied by the entire lighting device, and lowering manufacturing costs.

[0112] It should be noted that the first-stage optical component 21 and the second-stage optical component 31 are both mounted on the lens bracket 11, and the remaining components can be mounted sequentially on the module bracket 12, the first mounting plate 25 and the second mounting plate 35.

[0113] Furthermore, as some specific embodiments of this disclosure, referring to FIG12, the first module 2 of this disclosure also includes an anti-focusing structure 22 and a light-shielding structure 23. The anti-focusing structure 22, the light-shielding structure 23, and the first mounting plate 25 are sequentially disposed on the module support 12. The light-shielding structure 23 is configured to separate the first light beam and the second light beam. The anti-focusing structure 22 can prevent sunlight from focusing and burning the components. The light-shielding structure 23 is used to separate the first light beam and the second light beam, avoiding crosstalk between the light beams projected by the first light source 251 and the second light source 252. Furthermore, all component parts are fixedly connected to each other by screws to form the first module 2 as a whole.

[0114] In some specific embodiments, referring to Figure 9, the light-shielding structure 23 includes a light-shielding plate 231 and a light-shielding bracket 232, wherein the light-shielding plate 231 and the light-shielding bracket 232 can be two independent components or an integrally formed part.

[0115] As shown in Figure 20, the light shield 231 is provided with a cutoff line structure 233. After the first beam is converged by the first functional concentrator 241, part of the light is cut off by the cutoff line structure 233 and then projected by the first primary optical component 21 to form a near-beam pattern with a bright and dark cutoff line.

[0116] In some specific embodiments, referring to Figure 20, as a specific embodiment of the light-shielding plate 231, a light-blocking plate is provided below the rear end of the light-shielding plate 231. A cutoff line structure 233 is located at the center of the front end of the light-shielding plate 231. A light-passing opening is provided on the light-shielding plate, and a reflector is provided below the light-passing opening. An angle is formed between the reflective surface of the reflector and the light-shielding plate, and the light-passing opening is located below the cutoff line structure 233. The opening width of the light-passing opening is 5mm-15mm, and the angle between the reflective surface of the reflector and the light-shielding plate 231 is 10°-30°. The light-shielding plate, the light-shielding plate 231, and the reflector are integrally formed. The first beam emitted from the first light source 251 is converged by the first functional concentrator 241, and part of the light is then projected by the first-stage optical component 21 to form a near-beam pattern. Another part of the light is reflected by the reflector and enters the light-passing opening, then is projected by the first-stage optical component 21 to form a near-beam III region light pattern. In this way, there is no need to form other structures on the primary optical component 21 to achieve the near-beam III region light pattern.

[0117] More specifically, as shown in Figure 21, an angle is formed between the light-shielding plate 231 and the optical axis of the first-stage optical component 21, with the vertex of the angle being the focal point of the first-stage optical component 21, and the angle being 0° to 5°. A gap of 7-10 mm is formed between the light-passing port and the near-light emitting surface of the first functional condenser 241. Furthermore, a zone III light-emitting surface can also be formed on the near-light emitting surface, located above the light-shielding plate 231. The zone III light-emitting surface is set to adjust the refraction angle of the light used to form the near-light zone III light pattern, controlling the light that can reach the reflector, thereby controlling the luminous flux of the near-light zone III light pattern to prevent the near-light zone III light pattern from being too bright and not meeting regulatory requirements. In addition, the light-passing port and the reflector are located below the extension structure of the cutoff line structure 233 on the light-shielding plate 231. The reason is that the low beam III zone beam pattern is usually located above the low beam pattern cutoff line. The position of the light port and reflector corresponding to the cutoff line structure 233 can be set, which can reduce the angle requirement for the reflector. If the reflector is set elsewhere, then in order for the low beam III zone beam pattern to reach the specified position, the reflector must be deflected to the left or right, which will cause the later installation to be complicated and result in low beam pattern accuracy.

[0118] Meanwhile, as shown in Figure 21, the light-shielding plate 231 is rotated at a certain angle along the lens focal point, with the angle range being 0° to 5°, so that the light forming the low beam III zone light pattern can be emitted through the light-passing port. As shown in Figure 22, in order to avoid excessive energy above the low beam cutoff line causing glare, and at the same time to meet regulatory requirements, when designing the low beam III zone light pattern, energy "white space" is often left between the cutoff line of the main low beam pattern e and the low beam III zone light pattern d. The white space f is located between the low beam III zone light pattern d and the main low beam pattern e. It can be understood that "white space" means that the energy in the area from -0.57° to +1° at the low beam cutoff line "bathtub" is as weak as possible, where "bathtub" can be understood as the upper edge g of the light pattern of the main low beam pattern e, as shown in Figure 22.

[0119] Furthermore, since the lighting device will heat up after prolonged use, the lighting device provided in this embodiment of the present disclosure further includes a first heat sink 41 connected to the first mounting plate 25, and a second heat sink 42 mounted on the second mounting plate 35 in the first module 2. Additionally, the lighting device provided in this embodiment of the present disclosure may also include a heat dissipation bracket 43 and a fan 44, with the air outlet of the fan 44 connected sequentially to the first heat sink 41 and the second heat sink 42. The first heat sink 41 is used to dissipate heat from the first module 2, and the second heat sink 42 is used to dissipate heat from the second module 3. The heat dissipation bracket 43 serves both to mount the fan 44 and to act as an air duct to provide cool air to the first heat sink 41 and the second heat sink 42.

[0120] Based on the above specific embodiments and referring to Figure 9, as some specific embodiments of this disclosure, a lens retainer 13 and other components are also provided. The first-stage optical component 21 and the second-stage optical component 31 are fixedly installed to the lens retainer 13 and the lens bracket 11 respectively by retaining springs, while other components can also be fixed by snaps or bolts. In addition, patterns are provided on the light-emitting surface of the first-stage optical component 21, the light-emitting surface of the outer lens 311, and the light-emitting surface of the inner lens 312, making the light pattern projected by the illumination device more uniform and more aesthetically pleasing.

[0121] Secondly, in order to better understand the technical solution and usage method of this disclosure, the preferred embodiments are described below in conjunction with a relatively comprehensive list of preferred technical features:

[0122] Referring to Figures 1 to 9, a first aspect of this disclosure provides a lighting device including a first module 2 and a second module 3 mounted on a mounting mechanism 1. The second module 3 is capable of forming an adaptive light pattern c, and the first module 2 is capable of forming a first functional light pattern a and an auxiliary light pattern b. The adaptive light pattern c is superimposed with the auxiliary light pattern b to form a second functional light pattern. Specifically, the first functional light pattern a is a low-beam light pattern, the auxiliary light pattern b is an auxiliary high-beam light pattern, the adaptive light pattern c is an adaptive main high-beam light pattern, and the auxiliary light pattern b and the adaptive light pattern c are superimposed to form an adaptive high-beam light pattern.

[0123] As shown in Figures 2 and 9, the mounting mechanism 1 includes a lens bracket 11 and a module bracket 12. The lens bracket 11 is fitted onto the end of the module bracket 12, and the lens bracket 11 and the module bracket 12 are connected by snaps and bolts.

[0124] As shown in Figures 11 and 12, the first module 2 includes a primary optical component 21 serving as a projection lens, an anti-focusing structure 22, a light-shielding structure 23, a first primary optical component 24, and a first mounting plate 25. The anti-focusing structure 22 prevents sunlight from focusing and burning components. The projection lens is mounted on the lens holder 11 via a snap ring and lens retainer 13, enabling it to project light to form corresponding illumination patterns. The anti-focusing structure 22, light-shielding structure 23, first primary optical component 24, and first mounting plate 25 are sequentially connected to the module holder 12. A first heat sink 41 is also provided on the first mounting plate 25. The first mounting plate 25 is equipped with a first light source 251 serving as a near-beam source and a second light source 252 serving as a first high-beam source. The first primary optical component 24 includes a first functional concentrator 241 serving as a near-beam concentrator and an auxiliary concentrator 242 serving as a high-beam concentrator. The near-beam concentrator is correspondingly positioned to the near-beam source, and the high-beam concentrator is correspondingly positioned to the first high-beam source. The light-shielding structure 23 can separate the first beam projected by the first light source 251 and the second beam projected by the second light source 252. The light-shielding structure 23 includes a light-shielding plate 231 and a light-shielding bracket 232. A cutoff line structure 233 is formed on the light-shielding plate 231. Specifically, part of the first beam emitted from the low beam source is focused by the low beam concentrator, then cut off by the cutoff line structure 233, and then projected by the projection lens to form a low beam pattern with bright and dark cutoff lines. The second beam emitted from the first high beam source is focused by the high beam concentrator and then projected by the projection lens to form an auxiliary high beam pattern.

[0125] As shown in Figures 23 to 27, the second module 3 includes a second-stage optical component 31 with an outer lens 311 and an inner lens 312, a second primary optical component 33, a dimming bracket 34, and a second mounting plate 35. The outer lens 311 and the inner lens 312 are sequentially mounted on the lens bracket 11. The second primary optical component 33 is mounted on the second mounting plate 35. The dimming bracket 34 is adjustablely connected to the module bracket 12 via a first dimming structure, and is also adjustablely connected to the second mounting plate 35 via a second dimming structure. The second primary optical component 33 is mounted on the second mounting plate 35 via a heat sink 334. The second primary optical component 33 includes a condenser plate 331, a silicone condenser that is a combination of several light guide units 332, and a condenser bracket 333. The silicone condenser is fixed to the condenser bracket 333 via the condenser plate 331, and the condenser bracket 333 is mounted on the heat sink 334.

[0126] The first dimming structure includes a first connecting hole 344 formed on the module bracket 12 and a first dimming hole 341 formed on the dimming bracket 34, wherein the first dimming hole 341 is an oblong hole and the first connecting hole 344 is a threaded hole. A bolt, acting as a first adjusting member, moves along the length of the oblong hole (i.e., the first direction) under the influence of the first connecting hole 344, causing the dimming bracket 34 to move in the front-back direction. This allows the module bracket 12 to move relative to the dimming bracket 34 in the first direction parallel to the optical axis of the outer lens 311. When the desired direction is reached, the first connecting hole 344 and the first dimming hole 341 are fixedly connected by the bolt. A guide groove 343 is also provided around the module bracket 12, and a dimming protrusion 342 corresponding to the guide groove 343 is provided on the dimming bracket 344. The guide groove 343 matches the corresponding dimming protrusion 342, providing guidance for the movement of the dimming protrusion 342. The second dimming structure includes a second dimming hole 345 formed on the dimming bracket 34 and a second connecting hole 347 formed on the second mounting plate 35. A second dimming element 346 passes through the second dimming hole 345 and the second connecting hole 347, the diameter of which is smaller than the diameter of the second dimming hole 345. The second connecting hole 347, through the second adjusting element 346, moves the second mounting plate 35 relative to the dimming bracket 34 along a second or third direction, thereby adjusting the relative position between the dimming bracket 34 and the second mounting plate 35, so that the dimming bracket 34 moves relative to the second mounting plate 35 along a second direction and / or a third direction perpendicular to the optical axis of the outer lens 311. A third light source 351 is provided on one side of the second mounting plate 35, and a second heat sink 42 is provided on the other side. The third beam emitted from the third light source 351 is converged by the second primary optical component 33, propagated through the inner lens 32, and then projected by the outer lens 311 to form an adaptive main high beam pattern.

[0127] In addition, as shown in Figure 9, a heat dissipation bracket 43 and a fan 44 are also provided. The fan 44 is connected to the module bracket 12 through the heat dissipation bracket 43, and provides cool air to the first heat sink 41 and the second heat sink 42 through the heat dissipation bracket 43. In use, the low beam mode realizes the low beam illumination function, and the auxiliary high beam mode and the adaptive main high beam mode are superimposed to form the adaptive high beam illumination function.

[0128] In the preferred embodiment of the lighting device provided in the first aspect of this disclosure, the high and low beam integrated module and the adaptive high beam module are integrated into one design, so that the lighting device has both low beam lighting function and adaptive high beam lighting function, which reduces the number of parts, saves the cost of setting up two separate modules, and also saves installation space.

[0129] As can be seen, the lighting module provided by the first aspect of this disclosure occupies little space, can integrate modules with different functions, reduces the number of parts, and lowers costs.

[0130] A second aspect of this disclosure provides a vehicle lamp, including the lighting device provided in the first aspect, which is small in size and has low manufacturing cost.
