[0002] In the current headlight design, ADB (Adaptive Driving Beam) headlights are increasingly favored by the industry due to their excellent performance. ADB headlights can automatically change the headlight's high and low beam according to the current road conditions, thereby reducing the impact on other vehicles and improving the safety of the driver's field of vision.

[0003] At present, with the development of automotive lighting technology, the styling space adapted to the structure of the headlight components in the ADB headlight assembly structure layout is getting smaller and smaller, especially the Z-direction (i.e., the vehicle body height direction) dimension in the headlight layout space is getting narrower and narrower.

[0004] The traditional ADB solution cannot provide reliable performance in the case of narrow Z-direction space, and the design space is also limited. In particular, the common headlight layout solution on the market, which is composed of an inner lens and a single-focus focusing lens, usually has more divergent light when used in ADB headlights, and the component structure layout is more limited, which is mutually constrained by the current headlight layout requirements with small Z-direction space. As a result, this type of traditional headlight component layout structure cannot meet the current headlight design requirements under ultra-narrow Z-direction dimensions, resulting in the corresponding headlight performance being restricted.

[0005] In view of this, how to optimize the component structure layout of the ADB headlight assembly so that it can fit into the narrow assembly layout space and make its light more concentrated, so as to optimize the working performance of the headlight, is an important technical problem that technicians in this field currently need to solve.

[0019] Compared with the above-mentioned background technology, the light-emitting component provided by the utility model, during its assembly and operation, the light emitted by the upper light-emitting module is incident into the upper light-guiding module through one end of the upper light-guiding module close to the upper light-emitting module, and the light undergoes curved surface reflection at the upper total reflection curved surface, thereby utilizing the concave curved surface structure of the upper total reflection curved surface to focus and shape the light, thereby making the light pattern after being reflected by the upper total reflection curved surface more focused, and the light after being reflected by the upper total reflection curved surface undergoes a second reflection at the total reflection plane, thereby utilizing the inclined arrangement structure of the total reflection plane itself to form a plane reflection for the light, thereby reflecting the light to the upper focal point while maintaining the light pattern.

In this way, the upper light-emitting unit and the lower light-emitting unit cooperate with each other to effectively focus and shape the light, and the upper total reflection curved surface and the total reflection plane cooperate with each other to gather the light pattern and guide the light path in the horizontal direction for the light emitted from the upper light-emitting module, so that only a smaller layout space is required in the vertical direction to complete the focusing and horizontal propagation of the light, making the assembly structure of the light-emitting component in the Z direction of the vehicle body more compact, which can fully match the narrow Z-direction assembly space layout requirements of the headlight assembly, and the upper and lower light-emitting units are more sufficient and efficient in focusing and shaping the light, which can effectively avoid the divergence of edge light, so that the light emitted by the headlight assembly is more concentrated, optimizing the lighting effect and working performance of the headlight.

[0041] Please refer to Figures 1 to 7 .

[0042] In a specific embodiment, the light-emitting assembly provided by the utility model includes an upper light-emitting unit and a lower light-emitting unit, the upper light-emitting unit includes an upper light-emitting module 11, an upper light-guiding module 12 and an upper focus lens 13 arranged in sequence in a horizontal direction, the top of the upper light-guiding module 12 close to one end of the upper light-emitting module 11 has an upper total reflection curved surface 121, and the center of the upper total reflection curved surface 121 is located below the upper total reflection curved surface 121, the bottom of the upper light-guiding module 12 has an inclined total reflection plane 122, and the upper The vertical distance between the horizontal section of the total reflection surface 121 and the total reflection plane 122 increases from the end close to the upper light-emitting module 11 to the end away from the upper light-emitting module 11. The end of the upper light-guiding module 12 away from the upper light-emitting module 11 has an upper free surface 123, and the middle part of the upper free surface 123 protrudes toward the direction where the upper focal lens 13 is located. The upper light-emitting module 11, the upper total reflection surface 121, the total reflection plane 122, the upper free surface 123 and the upper focal lens 13 are arranged in sequence along the light path.

[0043] During the assembly and operation process, the light emitted by the upper light-emitting module 11 is incident into the upper light-guiding module 12 through one end of the upper light-guiding module 12 close to the upper light-emitting module 11, and the light undergoes curved surface reflection at the upper total reflection curved surface 121, thereby utilizing the concave curved surface structure of the upper total reflection curved surface 121 to focus and shape the light, so that the light pattern after being reflected by the upper total reflection curved surface 121 is more focused, and the light reflected by the upper total reflection curved surface 121 undergoes a second reflection at the total reflection plane 122, thereby utilizing the inclined arrangement structure of the total reflection plane 122 itself to form a planar reflection for the light, thereby reflecting the light to the upper focus lens 13 while maintaining the light pattern, and then processing the light into parallel light through the convex lens structure of the upper focus lens 13, so that the light can be irradiated to the illumination surface of the headlight assembly.

[0044] The lower light-emitting units are arranged one by one below the lower light-emitting unit, and the lower light-emitting unit includes a lower light-emitting module 21, a lower light-guiding module 22 and a lower focal lens 23 arranged in sequence along the horizontal direction. The top of the lower light-guiding module 22 close to one end of the lower light-emitting module 21 has a lower total reflection surface 221, and the center of the lower total reflection surface 221 is located below the lower total reflection surface 221. The end of the lower light-guiding module 22 away from the lower light-emitting module 21 has a lower free surface 222, and the middle part of the lower free surface 222 bulges toward the direction where the lower focal lens 23 is located. The lower light-emitting module 21, the lower total reflection surface 221, the lower free surface 222 and the lower focal lens 23 are arranged in sequence along the light path.

[0045] Corresponding to the working process of the above-mentioned upper light-emitting unit, the light emitted by the lower light-emitting module 21 is incident into the lower light-guiding module 22 via one end of the lower light-guiding module 22 close to the lower light-emitting module 21, and the light undergoes curved reflection at the lower total reflection surface 221, thereby utilizing the concave curved surface structure of the lower total reflection curved surface 221 to focus and shape the light, so that the light type reflected by the lower total reflection curved surface 221 is more focused, and the light reflected by the lower total reflection curved surface 221 is incident into the lower focus lens 23, thereby utilizing the convex lens structure of the lower focus lens 23 to process the light into parallel light, so that the light can be irradiated to the irradiation surface of the headlight assembly.

[0046] In this way, the upper light-emitting unit and the lower light-emitting unit cooperate with each other to effectively focus and shape the light, and the upper total reflection curved surface 121 and the total reflection plane 122 cooperate with each other to focus the light emitted by the upper light-emitting module 11 and guide the light path in the horizontal direction, so that only a smaller layout space is required in the vertical direction to complete the focusing and horizontal propagation of the light, so that the assembly structure of the light-emitting component in the Z direction of the vehicle body is more compact, which can fully match the narrow Z-direction assembly space layout requirements of the headlight assembly, and the upper and lower light-emitting units are more sufficient and efficient in focusing and shaping the light, which can effectively avoid the divergence of edge light, so that the light emitted by the headlight assembly is more concentrated, optimizing the lighting effect and working performance of the headlight.

[0047] Generally, there are at least two upper light-emitting units and two lower light-emitting units, each of which is arranged in sequence along the horizontal direction, and each of which is arranged in sequence along the horizontal direction, and the arrangement direction of the upper light-emitting units is parallel to the arrangement direction of the lower light-emitting units, and each of the upper light-emitting units is arranged in a one-to-one correspondence with each of the lower light-emitting units along the vertical direction. Accordingly, the upper focus lens 13 adapted to each upper light-emitting unit can be a plurality of lens components corresponding to the upper light-emitting units one by one, or a single lens component that can be adapted to each of the upper light-emitting units at the same time; similarly, the lower focus lens 23 adapted to each lower light-emitting unit can be a plurality of lens components corresponding to the lower light-emitting units one by one, or a single lens component that can be adapted to each of the lower light-emitting units at the same time.

[0048] In this way, on the basis of any upper light-emitting unit and any lower light-emitting unit forming a single pixel of the car light, multiple horizontally arranged upper light-emitting units and multiple horizontally arranged lower light-emitting units can cooperate to form a multi-pixel car light layout, so as to meet the needs of the matrix or other lighting layout of the ADB car light assembly in actual applications, thereby improving the overall performance and adaptability to working conditions of the car light assembly.

[0049] On this basis, if a component structure in which a plurality of upper focus lenses 13 are arranged in sequence is adopted, each upper focus lens 13 can be integrated into an integrated structure, so as to further improve the structural integration of the light-emitting component, make its component structure more compact and regular, thereby further reducing the required assembly space, so as to adapt to the more compact vehicle lamp space layout requirements; correspondingly, when a component structure in which a plurality of lower focus lenses 23 are arranged is adopted, each lower focus lens 23 can also be an integrated structure, so as to achieve the improvement of the structural integration of the light-emitting component as described above, so as to make the structure of the light-emitting component more compact, thereby meeting the needs of a narrower and more compact vehicle lamp structure layout.

[0050] In fact, in practical applications, the upper focus lens 13 and the lower focus lens 23 adapted to the same set of headlight assembly can all be integrated into the same lens component, so as to further reduce the number of components and optimize the difficulty of component processing and the process flow accordingly, so that the light-emitting component and its corresponding adapted headlight assembly structure are simpler and more reliable, and the processing and assembly are more convenient and efficient.

[0051] In practical applications, both the upper light guide module 12 and the lower light guide module 22 can be made of light-transmitting engineering plastics to optimize the reflection effect of the curved surface and plane structure inside each light guide module on light, and ensure the corresponding light type processing effect. Of course, the upper light guide module 12 and the lower light guide module 22 can also be arranged as a cavity component filled with light-guiding inert gas. In short, it should be ensured that the interior of each light guide module is a light-dense medium compared to the external air environment to avoid scattering of light when it is transmitted in each light guide module, thereby further ensuring the focusing processing effect of each light guide module on light, avoiding light divergence, maintaining the light type to match the actual application requirements of the headlight assembly, and optimizing the lighting effect of the headlight assembly.

[0052] Specifically, one end of the upper light guide module 12 close to the upper light emitting module 11 has an upper light incident plane 124 that is aligned with the light emitting surface of the upper light emitting module 11 to allow light to enter the upper light guide module 12, and the upper light incident plane 124 is parallel to the light emitting surface of the upper light emitting module 11, and the upper light incident plane 124 is located between the upper light emitting module 11 and the upper total reflection curved surface 121 along the light path; one end of the lower light guide module 22 close to the lower light emitting module 21 has a lower light incident plane 223 that is aligned with the light emitting surface of the lower light emitting module 21 to allow light to enter the lower light guide module 22, and the lower light incident plane 223 is parallel to the light emitting surface of the lower light emitting module 21, and the lower light incident plane 223 is located between the lower light emitting module 21 and the lower total reflection curved surface 221 along the light path. The upper light incident plane 124 can be arranged parallel to the light emitting surface of the upper light emitting module 11 and be matched with a gap, so that the light emitted by the upper light emitting module 11 can be irradiated to the upper light incident plane 124 as vertically as possible and smoothly and fully enter the upper light guide module 12, so as to avoid the light from being reflected at the upper light incident plane 124, thereby ensuring the light focusing processing efficiency and the corresponding light pattern processing effect of the upper light guide module 12; similarly, the lower light incident plane 223 can be arranged parallel to the light emitting surface of the lower light emitting module 21 and be matched with a gap, so that the light emitted from the lower light emitting module 21 can be irradiated to the lower light incident plane 223 as vertically as possible and smoothly and fully enter the lower light guide module 22, thereby ensuring the light focusing processing efficiency and the light pattern processing effect of the lower light guide module 22.

[0053] It is not difficult to understand that the upper total reflection surface 121 is a variable curvature surface. Generally, the distance between any point on the upper total reflection surface 121 and the upper light-emitting module 11 is inversely proportional to the curvature at the point, that is, the curvature of the upper total reflection surface 121 at one end close to the upper light-emitting module 11 is the largest, and the curvature of the upper total reflection surface 121 at one end away from the upper light-emitting module 11 is the smallest. Accordingly, the curvature of the upper total reflection surface 121 gradually decreases from its end close to the upper light-emitting module 11 to its end away from the upper light-emitting module 11. Of course, the curvature change of the upper total reflection surface 121 is not necessarily a linear change. In practical applications, the curvature of different parts of the upper total reflection surface 121 can be flexibly selected and adjusted according to actual working conditions and the adaptation requirements of the vehicle lamp, in order to obtain the best light reflection and light pattern adjustment effects.

[0054] In fact, the upper light incident plane 124 and the light emitting surface of the upper light emitting module 11 are both inclined, and their inclination directions are consistent with the inclination direction of the total reflection plane 122, and they differ only in the inclination angle. In this way, in conjunction with the variable curvature structure of the upper total reflection curved surface 121, the light incident on the upper light incident plane 124 can be subjected to maximum curved reflection adjustment at one end of the upper total reflection curved surface 121 close to the upper light incident plane 124, and at the end of the upper total reflection curved surface 121 far from the upper light incident plane 124, its curvature is extremely small, so that the end of the upper total reflection curved surface 121 far from the upper light incident plane 124 is close to a horizontally extended plane. In this way, the upper total reflection curved surface 121 can be arranged in a horizontal direction as a whole, thereby further reducing the component size of the light emitting component along the Z direction, making it more suitable for a narrower Z-direction assembly space, and meeting the structural layout requirements of the current ADB headlight assembly.

[0055] On the other hand, the light-emitting surface and the lower light-incident plane 223 of the lower light-emitting module 21 are also inclined structures in the same direction as the total reflection plane 122, but the lower total reflection surface 221 does not need to use a variable curvature plane. It is only necessary to ensure that the lower total reflection surface 221 is an inclined curved surface structure. Of course, the inclination direction of the lower total reflection surface 221 should be opposite to the lower light-incident plane 223, so as to ensure that the light entering the lower light guide module 22 through the lower light-incident plane 223 is smoothly reflected at the lower total reflection surface 221 and processed into a light beam that can propagate toward the lower free curved surface 222, thereby ensuring the light type processing effect of the lower light guide module 22.

[0056] Of course, in actual applications, the lower total reflection surface 221 can also use a variable curvature surface structure to meet the application requirements under different working conditions, improve the working condition adaptability of the light-emitting component, and optimize the working condition adaptation effect and working performance of the vehicle lamp assembly accordingly.

[0057] More specifically, the upper light incident plane 124 is coplanar with the lower light incident plane 223. In this way, it can be ensured that the light incident effects at the upper light incident plane 124 and the lower light incident plane 223 are relatively matched, so that the light pattern processed by the correspondingly arranged group of upper light emitting units and lower light emitting units is more adaptable, thereby making the light pattern processing effect of the light emitting component better and the working performance of the vehicle lamp assembly further optimized.

[0058] On this basis, the upper light-emitting module 11 and the lower light-emitting module 21 are both LED light-emitting modules, and the upper light-emitting module 11 and the lower light-emitting module 21 are located on the same LED board. Since the upper light-incident plane 124 and the lower light-incident plane 223 are coplanar, under conventional configuration, the light-emitting surface of the upper light-emitting module 11 and the light-emitting surface of the lower light-emitting module 21 are also coplanar. Considering that the upper light-emitting module 11 and the lower light-emitting module 21 are LED light-emitting modules of the same specifications, the upper light-emitting module 11 and the lower light-emitting module 21 can be arranged together on the same LED board, thereby further streamlining the component structure, simplifying the overall assembly process of the light-emitting component, and improving the assembly efficiency of the component. Arranging multiple light-emitting modules on the same board is conducive to the consistency of component assembly, thereby making the overall assembly structure layout of the light-emitting component more regular and compact, and the corresponding assembly space requirements can be further optimized.

[0059] It should be particularly emphasized that in actual applications, there is a gap fit between the upper light-emitting module 11 and the upper light-guiding module 12, and there is also a gap fit between the lower light-emitting module 21 and the lower light-guiding module 22. In this way, the matching gap between each light-emitting module and its corresponding light-guiding module can be utilized to improve the heat dissipation efficiency of each light-emitting module and its supporting components, optimize the overall heat dissipation effect of the component, avoid local overheating of components that may occur when the headlight assembly is running for a long time, and ensure the overall operating reliability and working condition tolerance of the light-emitting component and even the headlight assembly.

[0060] In addition, the upper light guide module 12 and the upper focal lens 13 are gap-matched in the horizontal direction, and the lower light guide module 22 and the lower focal lens 23 are gap-matched in the horizontal direction. This gap-matching structure helps to optimize the incident effect of the light emitted from each light guide module at the corresponding focal lens, and ensures the light pattern processing effect of each light-emitting unit. Of course, in actual applications, a matching slide rail and slider mechanism or a worm gear mechanism can be used to achieve the horizontal reciprocating movement of each focal lens, so as to appropriately adjust the axial spacing between each light guide module and its corresponding focal lens, so as to adapt to the light pattern adjustment requirements under different working conditions, and further improve the working condition adaptability of the light-emitting component and the overall working performance of the vehicle lamp assembly.

[0061] Please focus on the reference Figure 7 ,like Figure 7 As shown, in actual assembly, the lower light-emitting unit is arranged below the upper light-emitting unit, so Figure 7 In the top view of the structure shown, only the top structure where the upper light-emitting unit is located can be observed. It should be understood that in Figure 7 In the viewing angle shown, each lower light-emitting unit has been blocked by its corresponding upper light-emitting unit.

[0062] In a specific implementation, the ADB headlight assembly provided by the utility model includes a lamp housing and a light-emitting component located in the lamp housing, wherein the light-emitting component is the light-emitting component described above. The light-emitting component of the ADB headlight assembly can make the Z-direction component structure of the ADB headlight assembly more compact to match the narrow assembly space, and make the light of the headlight more concentrated, thereby optimizing the working performance of the headlight.

[0063] Furthermore, there are at least two light-emitting components, and each of the light-emitting components is arranged in sequence along a direction perpendicular to the light path. In practical applications, multiple light-emitting components cooperate with each other, and the specific arrangement positions of each light-emitting component and the relative positions between each other can be flexibly adjusted according to actual working conditions, so as to match the layout requirements and lighting needs of the ADB headlight assembly under different working conditions, thereby further optimizing the working condition adaptability and working performance of the ADB headlight.

[0064] In summary, it can be seen that during the assembly and operation of the light-emitting component provided in the utility model, the light emitted by the upper light-emitting module enters the upper light-guiding module through the end of the upper light-guiding module close to the upper light-emitting module, and the light undergoes curved surface reflection at the upper total reflection curved surface, thereby utilizing the concave curved surface structure of the upper total reflection curved surface to focus and shape the light, so that the light shape after being reflected by the upper total reflection curved surface is more focused, and the light after being reflected by the upper total reflection curved surface undergoes a second reflection at the total reflection plane, thereby utilizing the inclined arrangement structure of the total reflection plane itself to form a plane reflection for the light, thereby reflecting the light to the upper focal point while maintaining the light shape. The light is then processed into parallel light by the convex lens structure of the upper focal lens so that the light can be irradiated to the irradiation surface of the headlight assembly; at the same time, the light emitted by the lower light-emitting module is injected into the lower light-guiding module through one end of the lower light-guiding module close to the lower light-emitting module, and the light is reflected at the lower total reflection curved surface, so that the concave curved surface structure of the lower total reflection curved surface is used to focus and shape the light, so that the light type after reflection by the lower total reflection curved surface is more concentrated, and the light after reflection by the lower total reflection curved surface is injected into the lower focal lens, so that the convex lens structure of the lower focal lens is used to process the light into parallel light so that the light can be irradiated to the irradiation surface of the headlight assembly. In this way, the upper light-emitting unit and the lower light-emitting unit cooperate with each other to effectively focus and shape the light, and the upper total reflection curved surface and the total reflection plane cooperate with each other to gather the light pattern and guide the light path in the horizontal direction for the light emitted from the upper light-emitting module, so that only a smaller layout space is required in the vertical direction to complete the focusing and horizontal propagation of the light, making the assembly structure of the light-emitting component in the Z direction of the vehicle body more compact, which can fully match the narrow Z-direction assembly space layout requirements of the headlight assembly, and the upper and lower light-emitting units are more sufficient and efficient in focusing and shaping the light, which can effectively avoid the divergence of edge light, so that the light emitted by the headlight assembly is more concentrated, optimizing the lighting effect and working performance of the headlight.

[0065] The utility model also provides an ADB headlight assembly, whose light-emitting components can make the Z-direction component structure of the ADB headlight assembly more compact to match the narrow assembly space, and make the light of the headlight more concentrated, thereby optimizing the working performance of the headlight.

[0066] The above is a detailed introduction to the light-emitting component provided by the utility model and the ADB headlight assembly using the light-emitting component. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
