Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to an automotive lighting module and a vehicle. Background Technology

[0002] The vehicle is equipped with various lights that have illumination and signaling functions, which play a key role in nighttime lighting, daytime signal transmission, and increasing vehicle visibility.

[0003] With the development of technology, mid-to-high-end car models have begun to explore the scenario-based application of headlights. One type of headlight technology, however, struggles to achieve a dazzling starlight effect, resulting in a lack of premium feel and driving experience. Utility Model Content

[0004] This application proposes a vehicle headlight module and vehicle, aiming to achieve a dazzling starlight effect in the headlights to enhance the vehicle's premium feel and user experience.

[0005] In a first aspect, embodiments of this application propose a vehicle lighting module, comprising: a light-emitting substrate, including a plurality of LED (Light Emitting Diode) chips arranged in an array; a first transparent element disposed on the light-emitting side of the light-emitting substrate, wherein the surface of the first transparent element facing away from the light-emitting substrate is composed of a plurality of first sub-planes spliced ​​together, wherein any two adjacent first sub-planes are not coplanar; and a reflective film layer disposed on the surface of the first transparent element near the light-emitting substrate, wherein the reflective film layer is provided with a plurality of light-transmitting holes, and each LED chip corresponds to at least one of the light-transmitting holes.

[0006] In the vehicle headlight module of this application embodiment, when all the LED chips are not lit, the external ambient light shines onto the reflective film layer through the first transparent component. After being reflected by the reflective film layer, the light enters the first transparent component at multiple first sub-planes and is transmitted and refracted, thereby forming a static, transparent and dazzling lighting effect.

[0007] When at least some of the LED chips are lit, the light from each LED chip is emitted through at least one light-transmitting hole to the first transparent element. At this time, numerous light rays reach multiple first sub-planes. The multiple first sub-planes transform the planar optical effect into a multi-angle composite light field. Each first sub-plane can form an independent optical micro-region, resulting in a discrete distribution of light scattering directions. The light rays are transmitted in multiple directions due to the angular differences between different first sub-planes. Combined with the high-density light source, this creates a dazzling starlight effect. Therefore, the vehicle lighting module of this application embodiment can achieve a dazzling starlight effect both when the light source is on and off, thereby enhancing the vehicle's premium feel and user experience.

[0008] In some embodiments, each LED chip corresponds to a plurality of light-transmitting holes, the plurality of light-transmitting holes being arranged around the LED chip, and the graphic shape enclosed by the plurality of light-transmitting holes being at least one of a circle, a triangle, a rectangle, and a parallelogram.

[0009] This configuration allows for omnidirectional light emission from each LED chip, improving its light extraction efficiency. Secondly, the regular pattern optimizes the spacing and density of the apertures. This not only enhances the ease of aperture placement but also allows for more diverse arrangements of the equivalent high-density light source formed by multiple apertures, as the shapes of these virtual pixel groups can be identical or different. This further increases the dispersion of light emission, enhancing the dazzling starlight effect and ultimately improving the vehicle's visual sophistication and recognizability.

[0010] In some embodiments, each LED chip corresponds to a plurality of light-transmitting holes, wherein the aperture of the light-transmitting holes is less than or equal to 0.1 mm and the size of the LED chip is greater than or equal to 0.3 mm.

[0011] This embodiment uses ordinary LED chips with light-transmitting holes in the reflective film layer to replace light sources such as MiniLED and MicroLED in related technologies. This helps to significantly reduce the manufacturing cost of the headlight module while ensuring the starlight effect of the headlight, thereby helping to reduce the production cost of the vehicle.

[0012] Furthermore, by setting the aperture of the light-transmitting holes to less than or equal to 0.1 mm, on the one hand, the size of each virtual pixel can be reduced to accommodate more light-transmitting holes, thereby improving the light source density. On the other hand, the size of the light-transmitting holes is at the micrometer level, invisible to the naked eye, thus reducing the probability of multiple light-transmitting holes being directly recognized by the human eye. This is beneficial for further improving the static and dynamic lighting effects, thereby enhancing the vehicle's premium feel and overall experience.

[0013] In some embodiments, the spacing between any two adjacent light-transmitting holes is the same.

[0014] This design facilitates the arrangement of multiple light-transmitting holes on the reflective film layer.

[0015] In some embodiments, the minimum distance between any two adjacent light-transmitting holes is greater than or equal to 0.075 mm and less than or equal to 0.1 mm.

[0016] This embodiment limits the minimum spacing within the aforementioned range. Firstly, it allows for the use of mature photolithography and laser processing technologies, resulting in high yield and low cost, thus reducing production costs. Secondly, it enables high-density light-transmitting holes, effectively achieving high resolution, which improves the static and dynamic starlight effects of the headlights. Thirdly, it reduces the probability of densely packed holes forming in the reflective film layer, thereby improving the static appearance of the headlight module. Fourthly, the proportion of holes in the reflective film layer is not excessive, ensuring the structural strength of the reflective film layer, which in turn improves the reliability and stability of the headlight module.

[0017] In some embodiments, the vehicle headlight module further includes a light-blocking bracket disposed between the reflective film layer and the light-emitting substrate, and the light-blocking bracket has a plurality of light-blocking holes corresponding one-to-one with the LED chip.

[0018] This design ensures that the light emitted by each LED chip can only enter the corresponding multiple light-transmitting holes in the reflective film layer through the corresponding light-blocking holes, forming a physical light-shielding barrier and confining the emitted light from each LED chip within the range of its corresponding light-blocking holes. Firstly, this helps ensure that the light from each light-transmitting hole primarily originates from its corresponding LED chip, maintaining the optical independence of the virtual pixels and achieving a clear and distinct point matrix light source. Secondly, the light-blocking holes collimate and constrain the light, allowing the light from the LED chip to enter the light-transmitting holes of the reflective film layer at a more concentrated angle, enabling more precise multi-angle light field separation and resulting in a more discrete distribution of scattered light. This further enhances the starlight effect and sense of depth of the light. Furthermore, the light-blocking bracket, as a physical support structure between the reflective film layer and the light-emitting substrate, can fix the distance between them and provide a positioning reference, thereby simplifying the assembly process and improving assembly convenience and reliability.

[0019] In some embodiments, the headlight module further includes a second transparent element, which is disposed on the side of the first transparent element away from the light-emitting substrate. The surface of the second transparent element near the first transparent element is composed of a plurality of second sub-planes spliced ​​together, and any two adjacent second sub-planes are not coplanar.

[0020] This design allows light to undergo double refraction and scattering through the first sub-plane of the first transparent component and the second sub-plane of the second transparent component. This, on the one hand, helps to further enhance the dazzling starlight effect of the headlight module in both static and dynamic conditions, significantly improving the vehicle's technological and premium feel. On the other hand, the air insulation layer formed between the two transparent components not only improves the heat dissipation of the headlight module but also enhances its structural strength and reliability.

[0021] In some embodiments, the shape of the side surface of the second transparent member near the first transparent member is the same as the shape of the side surface of the first transparent member near the second transparent member.

[0022] This setup allows for the simultaneous molding of the light-emitting surface of the first transparent component and the incident surface of the second transparent component using a single mold, which helps to further reduce costs and improve production efficiency.

[0023] In some embodiments, the number of the first subplane and / or the number of the second subplane is greater than or equal to 500.

[0024] In this way, each of the first sub-planes forms a tiny refractive surface, allowing the light-emitting surface of the first transparent part to form a three-dimensional crystal pattern, which helps to further enhance the starlight effect of the headlight module.

[0025] In some embodiments, the side surface of the second transparent element facing away from the first transparent element is composed of a plurality of third sub-planes, wherein any two adjacent third sub-planes are not coplanar, and the number of the second sub-planes is 20 to 120 times the number of the third sub-planes.

[0026] With this setup, firstly, the light-emitting surface of the second transparent component is easier to process and has a lower processing cost, while the numerous tiny third sub-planes of the second transparent component can achieve more delicate scattering and refraction, thus achieving a more dazzling crystal starlight effect. This balance can be achieved between the lighting effect of the car headlight module and the processing cost and difficulty.

[0027] Secondly, embodiments of this application provide a vehicle including the headlight module described in the first aspect.

[0028] The vehicle in this embodiment uses the headlight module described in the first aspect. The headlight module can achieve a dazzling starlight effect when the light source is on and off, thereby improving the vehicle's premium feel and user experience. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] like Figures 1 to 4 As shown, in a first aspect, this application provides a vehicle headlight module 10. The vehicle headlight module 10 includes a light-emitting substrate 100, a first transparent element 200, and a reflective film layer 300. The light-emitting substrate 100 includes a plurality of LED chips 110 arranged in an array. The first transparent element 200 is disposed on the light-emitting side of the light-emitting substrate 100. The surface of the first transparent element 200 facing away from the light-emitting substrate 100 is formed by splicing together a plurality of first sub-planes 201. Any two adjacent first sub-planes 201 are not coplanar. The reflective film layer 300 is disposed on the surface of the first transparent element 200 close to the light-emitting substrate 100. The reflective film layer 300 is provided with a plurality of light-transmitting holes 301, and each LED chip 110 corresponds to at least one light-transmitting hole 301.

[0050] The vehicle lighting module 10 of this application embodiment includes a light-emitting substrate 100, a first transparent element 200, and a reflective film layer 300. The vehicle lighting module 10 can be, for example, a headlight, taillight, signal light, or ambient lighting. The light-emitting substrate 100 provides visible light and includes an LED chip 110. The light-emitting substrate 100 also includes a driving circuit board 120, on which a driving circuit is disposed. The LED chip 110 is electrically connected to the driving circuit board 120, and under the action of the driving circuit board 120, dimming control of the LED chip 110 can be achieved. Optionally, the driving circuit board 120 can be one of a ceramic substrate, a printed circuit board (PCB), or a metal substrate; this application does not limit this.

[0051] The first transparent element 200 can be made of materials such as optical glass, polycarbonate (PC), and acrylic (PMMA). The first transparent element 200 has high light transmittance, allowing light to pass through and exit.

[0052] The surface of the first transparent element 200 facing away from the light-emitting substrate 100 is composed of several first sub-planes 201, and any two adjacent first sub-planes 201 are not coplanar. The complexity of the shape of the surface of the first transparent element 200 facing away from the light-emitting substrate 100 varies depending on the number of first sub-planes 201.

[0053] If the number of first sub-planes 201 is small, then the area of ​​each first sub-plane 201 is large. In this case, the surface of the first transparent element 200 can be regarded as an irregular prism or polyhedral surface formed by multiple first sub-planes 201 with large areas.

[0054] If the number of first subplanes 201 is large, then the area of ​​each first subplane 201 will be small. In this case, if... Figure 1 As shown, the surface of the first transparent element 200 can be viewed as an irregular crystal three-dimensional pattern surface formed by a plurality of tiny first sub-planes 201.

[0055] In other words, as the number of first sub-planes 201 increases, the shape of the surface becomes more complex.

[0056] The reflective film layer 300 can be a standalone reflective film, or it can be a reflective layer formed on the surface of the first transparent component 200 through processes such as magnetron sputtering or electron beam evaporation. The reflective film layer 300 has multiple light-transmitting holes 301, and each LED chip 110 corresponds to at least one light-transmitting hole 301. That is, as shown... Figure 5 and Figure 6 As shown, the light emitted from each LED chip 110 can be transmitted into the first transparent element 200 through at least one light-transmitting hole 301. The number of LED chips 110 and the number of light-transmitting holes 301 have a one-to-one or one-to-many relationship. It can be understood that the more light-transmitting holes 301 corresponding to each LED chip 110, the higher the light utilization rate of the light source, thereby helping to reduce the energy consumption of the vehicle lighting module 10 and improve energy efficiency. At the same time, the better the light-splitting effect of each LED chip 110, the higher the light source density.

[0057] It should be noted that each LED chip 110 on the light-emitting substrate 100 can achieve independent brightness control under the drive of the driving circuit board 120. The LED chips 110 are classified into conventional LEDs, mini LEDs, and Micro LEDs according to their size. Mini LEDs and Micro LEDs can achieve sub-pixel and pixel-level arrangements, while conventional LEDs, due to their larger size, cannot achieve pixel-level arrangements like Mini LEDs and Micro LEDs. However, it is understandable that when the LED chip 110 is a conventional LED, each LED chip 110 can correspond to multiple light-transmitting holes 301. Thus, the emitted light from each conventional LED chip 110 can be split through multiple light-transmitting holes 301. Each light-transmitting hole 301 can be considered a virtual pixel, and the actual pixel density is determined by the number of light-transmitting holes 301, not the number of LED chips 110. In other words, when the LED chip 110 uses a conventional LED, the light-emitting substrate 100 and the light-transmitting hole 301 of the reflective film layer 300 can be combined to achieve a pixel density similar to Mini LED and Micro LED by increasing the arrangement density of the light-transmitting hole 301, thereby significantly improving the density of the point light source.

[0058] The specific principle behind the starlight-like lighting effect achieved by the headlight module 10 is as follows:

[0059] When all the LED chips 110 are not lit, the ambient light shines through the first transparent element 200 onto the reflective film layer 300. After being reflected by the reflective film layer 300, the light enters the first transparent element 200 at multiple first sub-planes 201 for transmission and refraction, thus forming a static, transparent and dazzling lighting effect.

[0060] When at least some of the LED chips 110 are lit, the light from each LED chip 110 is emitted through at least one light-transmitting hole 301 to the first transparent element 200. At this time, numerous light rays reach multiple first sub-planes 201. The multiple first sub-planes 201 transform the planar optical effect into a multi-angle composite light field. Each first sub-plane 201 can form an independent optical micro-region, resulting in a discrete distribution of light scattering directions. The light rays will be transmitted in multiple directions due to the angular differences of different first sub-planes 201, thus forming a dazzling starlight effect when combined with a high-density light source. It can be understood that when the number of first sub-planes 201 is small, the surface forms an irregular prism, which can create a dazzling starlight effect. As the number of first sub-planes 201 gradually increases, the surface of the first transparent component 200 can be regarded as an irregular crystal three-dimensional pattern surface formed by numerous tiny first sub-planes 201. Light will undergo more delicate transmission and refraction, thereby forming a crystal-like dazzling matrix of light points, creating a more exquisite and textured light and shadow effect, making the starlight effect of the lights more outstanding, and thus maximizing the vehicle's sense of luxury and recognizability at the visual level.

[0061] Therefore, the headlight module 10 of this application embodiment can achieve a dazzling starlight effect when the light source is on and off, which helps to improve the vehicle's premium feel and user experience.

[0062] like Figure 5 and Figure 6 As shown, in some embodiments, each LED chip 110 corresponds to a plurality of light-transmitting holes 301, which are arranged around the LED chip 110, and the shape of the pattern formed by the plurality of light-transmitting holes 301 is at least one of a circle, a triangle, a rectangle, and a parallelogram.

[0063] Multiple light-transmitting holes 301 are arranged around the LED chip 110. That is, the multiple light-transmitting holes 301 corresponding to each LED chip 110 are located at the circumferential edge of the LED chip 110. This allows each LED chip 110 to emit light at all circumferential angles, thereby improving the light emission efficiency of the LED chip 110. In addition, since the multiple light-transmitting holes 301 are located at the edge of the LED chip 110, the LED structure is not directly exposed through the light-transmitting holes 301, which also helps to improve the static appearance of the vehicle headlight module 10.

[0064] Furthermore, the multiple light-transmitting holes 301 corresponding to each LED chip 110 can be regarded as a group of virtual pixel groups. The shape of the multiple virtual pixel groups can be at least one of circles, triangles, rectangles, and parallelograms. Regular shapes can optimize the spacing and arrangement density of the holes. On the one hand, it is beneficial to improve the convenience of setting the light-transmitting holes 301. On the other hand, the shapes of the multiple virtual pixel groups can be exactly the same or not exactly the same, which can also improve the arrangement diversity of the high-density light source formed by the multiple light-transmitting holes 301, further improving the dispersion of light emission, thereby further enhancing the dazzling starlight effect of the lights, and thus further enhancing the vehicle's visual sense of sophistication and recognizability.

[0065] It should be noted that, although the specific number of the plurality of light-transmitting holes 301 corresponding to each LED chip 110 is not limited in the above embodiments, the shape limitation actually implies a minimum number of the plurality of light-transmitting holes 301 corresponding to each LED chip 110. For example, if the shape formed by the plurality of light-transmitting holes 301 is a triangle or a circle, then the minimum number of the plurality of light-transmitting holes 301 corresponding to each LED chip 110 is three. If it is a triangle, the three holes are located at the three vertices of the triangle; if it is a circle, the minimum three light-transmitting holes 301 can determine a circle with a unique radius. If the number is greater, the extra light-transmitting holes 301 can be distributed on the sides of the triangle or circle. As another example, if the shape formed by the plurality of light-transmitting holes 301 is a rectangle or a parallelogram, then the minimum number of the plurality of light-transmitting holes 301 corresponding to each LED chip 110 is four, and they are located at the four vertices. If the number is greater, the extra light-transmitting holes 301 can also be distributed on the sides of the shape. The specific number of light-transmitting holes 301 corresponding to each LED chip 110, and the resulting pattern shape, can be flexibly designed according to actual conditions. Optionally, when the LED chip 110 is a Mini / Micro LED, the number of light-transmitting holes 301 corresponding to each LED chip 110 can be less than the number of light-transmitting holes 301 corresponding to each LED chip 110 when the LED chip 110 is a conventional LED.

[0066] In one specific embodiment, such as Figure 5 and Figure 6 As shown, the LED chip 110 is a conventional chip with a size greater than or equal to 0.3 mm. Each LED chip 110 corresponds to four light-transmitting holes 301, which form a rhombus shape, with the LED chip 110 located at the center of the rhombus. This arrangement creates a symmetrical optical structure, where the light intensity of the two light-transmitting holes 301 at one diagonal is greater than that of the two light-transmitting holes 301 at the other diagonal. This allows for differentiated brightness across the multiple light-transmitting holes 301, further enhancing the starlight effect and sense of depth of the lighting.

[0067] In some embodiments, each LED chip 110 corresponds to a plurality of light-transmitting holes 301, the aperture of the light-transmitting holes 301 is less than or equal to 0.1 mm, and the size of the LED chip 110 is greater than or equal to 0.3 mm.

[0068] In other words, in this embodiment, the LED chip 110 is a conventional LED, which significantly reduces costs compared to micron-sized Mini / Micro LEDs. Meanwhile, the light-passing aperture 301 is a micron-sized aperture, approaching the pixel-level size of Mini LEDs and Micro LEDs. As mentioned above, the function of the light-passing aperture 301 is to enable light transmission and beam splitting for each LED chip 110, thereby increasing the light source density while emitting light.

[0069] In this embodiment, by using a large-size conventional LED chip 110 in conjunction with a reflective film layer 300 featuring micron-level light-transmitting holes 301, the density of the light source can be significantly increased, achieving the pixel density of Mini LEDs and Micro LEDs. Furthermore, combined with the multi-angle composite light field of multiple first sub-planes 201 of the first transparent element 200, a static, transparent, and dazzling lighting effect can be formed under ambient light when the light source is not illuminated. When the light source is illuminated, a dynamic, dazzling starlight effect is created, thereby enhancing the vehicle's premium feel and user experience. This embodiment uses a common LED chip 110 with high-density light-transmitting holes 301 instead of Mini LEDs and Micro LEDs, which helps to significantly reduce the manufacturing cost of the headlight module 10 while maintaining the starlight effect of the headlights, thus contributing to lower vehicle production costs.

[0070] Furthermore, by setting the aperture of the light-transmitting hole 301 to less than or equal to 0.1 mm, on the one hand, the size of each virtual pixel can be reduced to accommodate more light-transmitting holes 301, thereby further improving the light source density. On the other hand, the size of the light-transmitting hole 301 is at the micrometer level, invisible to the naked eye, thus reducing the probability of multiple light-transmitting holes 301 being directly recognized by the human eye. This is beneficial for further improving the static and dynamic lighting effects, thereby enhancing the vehicle's premium feel and overall experience.

[0071] Optionally, the aperture of the light-transmitting hole 301 can be, for example, 0.05mm, 0.055mm, 0.06mm, 0.065mm, 0.07mm, 0.075mm, 0.08mm, 0.085mm, 0.09mm, 0.095mm, 0.1mm, etc., and can be flexibly set according to the actual situation. Optionally, the LED chip 110 can be any conventional-sized LED chip in the prior art.

[0072] Optionally, the light-transmitting hole 301 can be formed by laser engraving or by photolithography, and this application does not limit it in this regard.

[0073] In some embodiments, the spacing between any two adjacent light-transmitting holes 301 is the same. This arrangement facilitates the arrangement of multiple light-transmitting holes 301 on the reflective film layer 300.

[0074] Furthermore, the minimum distance between any two adjacent light-transmitting holes 301 is greater than or equal to 0.075 mm and less than or equal to 0.1 mm.

[0075] If the minimum spacing between any two adjacent light-transmitting holes 301 is less than 0.075mm, the manufacturing process becomes more difficult, costly, and yields lower. Furthermore, excessively close light-transmitting holes 301 will create dense voids, affecting the static appearance of the headlight module 10. If the minimum spacing is greater than 0.1mm, the density improvement of the light-transmitting holes 301 is limited, failing to simulate the high-resolution effects of Mini LED and Micro LED, resulting in insufficient static and dynamic starlight effects.

[0076] Therefore, this embodiment limits the minimum spacing to the aforementioned range. Firstly, it allows for the use of mature photolithography and laser processing technologies, resulting in high yield and low cost, thus reducing production costs. Secondly, it enables high-density light-transmitting holes 301, effectively achieving high resolution, which improves the static and dynamic starlight effects of the headlights. Thirdly, it reduces the probability of densely packed holes forming in the reflective film layer 300, thereby improving the static appearance of the headlight module 10. Fourthly, the proportion of holes in the reflective film layer 300 is not too high, ensuring the structural strength of the reflective film layer 300, which in turn improves the reliability and stability of the headlight module 10.

[0077] like Figure 1 and Figure 2 As shown, in some embodiments, the vehicle headlight module 10 further includes a light-blocking bracket 400, which is disposed between the reflective film layer 300 and the light-emitting substrate 100. The light-blocking bracket 400 has a plurality of light-blocking holes 410 corresponding one-to-one with the LED chip 110.

[0078] In this embodiment, the light-blocking bracket 400 has a plurality of light-blocking holes 410 corresponding one-to-one with the LED chips 110. That is, each light-blocking hole 410 allows light from one LED chip 110 to pass through while blocking light from other LED chips 110. The light from the LED chip 110 passes through the light-blocking hole 410 and enters at least one corresponding light-transmitting hole 301. This arrangement ensures that the light emitted by each LED chip 110 can only enter the corresponding light-transmitting hole 301 of the reflective film layer 300 through the corresponding light-blocking hole 410, forming a physical light-shielding barrier and limiting the emitted light from each LED chip 110 to the range of the corresponding light-blocking hole 410. Firstly, this helps to ensure that the light from each light-transmitting hole 301 mainly comes from the corresponding LED chip 110, maintaining the optical independence of the virtual pixels and achieving a clear and distinct point matrix light source. Secondly, the light-blocking aperture 410 collimates and constrains the light, allowing the light from the LED chip 110 to enter the light-transmitting aperture 301 of the reflective film at a more concentrated angle. This enables more precise multi-angle light field separation, resulting in a more discrete distribution of scattered light. This, in turn, helps to further enhance the dazzling starlight effect and sense of depth of the light. Furthermore, the light-blocking bracket 400, as the physical support structure between the reflective film 300 and the light-emitting substrate 100, can fix the distance between the two and provide a positioning reference, thereby simplifying the assembly process and improving assembly convenience and reliability.

[0079] Optionally, the light-blocking bracket 400 can be composed of multiple horizontally and vertically distributed side beams arranged in a cross pattern to form multiple grids, each grid being a light-blocking hole 410. Optionally, refer to... Figure 1 and Figure 2 The outermost ring of light-blocking holes 410 around the light-blocking bracket 400 can be made without the outer side beam, thus forming an open light-blocking hole 410. This helps to reduce the material used in the light-blocking bracket 400 and thus save costs.

[0080] like Figures 7 to 9 As shown, in some embodiments, the vehicle headlight module 10 further includes a second transparent element 500. The second transparent element 500 is disposed on the side of the first transparent element 200 away from the light-emitting substrate 100. The surface of the second transparent element 500 near the first transparent element 200 is formed by splicing together a plurality of second sub-planes 501, and any two adjacent second sub-planes 501 are not coplanar.

[0081] In this embodiment, the headlight module 10 further includes a second transparent element 500, and the surface of the second transparent element 500 near the first transparent element 200 is composed of multiple second sub-planes 501. This arrangement allows light to undergo double refraction and scattering through the first sub-plane 201 of the first transparent element 200 and the second sub-plane 501 of the second transparent element 500. This, on the one hand, helps to further enhance the dazzling starlight effect of the headlight module 10 in both static and dynamic conditions, significantly improving the vehicle's technological and premium feel. On the other hand, the air insulation layer formed between the two transparent elements not only improves the heat dissipation of the headlight module 10 but also enhances its structural strength and reliability.

[0082] like Figure 9 As shown, in some embodiments, the shape of the side surface of the second transparent member 500 near the first transparent member 200 is the same as the shape of the side surface of the first transparent member 200 near the second transparent member 500.

[0083] This setup allows for the simultaneous molding of the light-emitting surface of the first transparent component 200 and the incident surface of the second transparent component 500 using a single mold, which helps to further reduce costs and improve production efficiency.

[0084] like Figures 7 to 9 As shown, in some embodiments, the number of first sub-planes 201 is greater than or equal to 500. In this way, each first sub-plane 201 constitutes a micro-refracting surface, so that the light-emitting surface of the first transparent element 200 can form a crystal three-dimensional pattern surface, thereby helping to further improve the starlight effect of the headlight module 10.

[0085] like Figures 7 to 9 As shown, in some embodiments, the number of second sub-planes 501 is greater than or equal to 500. In this way, each second sub-plane 501 constitutes a micro-refracting surface, allowing the incident surface of the second transparent element 500 to form a crystal three-dimensional pattern surface, thereby further enhancing the starlight effect of the headlight module 10.

[0086] like Figures 7 to 9 As shown, in some embodiments, the surface of the second transparent element 500 facing away from the first transparent element 200 is composed of a plurality of third sub-planes 502, and any two adjacent third sub-planes 502 are not coplanar. The number of second sub-planes 501 is 20 to 120 times the number of third sub-planes 502.

[0087] With this setup, firstly, the light-emitting surface of the second transparent component 500 is easier to process and has a lower processing cost, while the numerous tiny third sub-planes 502 of the second transparent component 500 can achieve more detailed scattering and refraction, thereby achieving a more dazzling crystal star effect. This balance can be achieved between the lighting effect of the headlight module 10 and the processing cost and difficulty.

[0088] Secondly, embodiments of this application provide a vehicle including the headlight module 10 described in the first aspect.

[0089] When all the LED chips 110 are not lit, the ambient light shines through the first transparent element 200 onto the reflective film layer 300. After being reflected by the reflective film layer 300, the light enters the first transparent element 200 at multiple first sub-planes 201 for transmission and refraction, thus forming a static, transparent and dazzling lighting effect.

[0090] When at least some of the LED chips 110 are lit, the light from each LED chip 110 is emitted through at least one light-transmitting hole 301 to the first transparent element 200. At this time, numerous light rays reach multiple first sub-planes 201. The multiple first sub-planes 201 transform the planar optical effect into a multi-angle composite light field. Each first sub-plane 201 can form an independent optical micro-region, resulting in a discrete distribution of light scattering directions. The light rays will be transmitted in multiple directions due to the angular differences of different first sub-planes 201, and with the high-density light source, a dazzling starlight effect is formed. Therefore, the vehicle headlight module 10 of this application embodiment can achieve a dazzling starlight effect when the light source is lit and turned off, thereby improving the vehicle's premium feel and user experience.

[0091] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
