Abstract
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 uses a light source to directly illuminate a crystal component, aiming to achieve a starlight-like lighting effect to enhance the vehicle's premium feel and overall experience.
[0004] However, the headlights with the above-mentioned structure do not have a visually obvious starlight effect, and the light lacks a sense of layering, resulting in a poor visual effect. Utility Model Content
[0005] This application proposes a vehicle headlight module and vehicle, aiming to improve the poor starlight effect and lack of layering of the headlights, thereby enhancing the vehicle's premium feel and user experience.
[0006] In a first aspect, embodiments of this application propose a vehicle lighting module. The vehicle lighting module includes: a transparent optoelectronic component for emitting and transmitting light; a first transparent element disposed on one side surface of the transparent optoelectronic component, wherein a semi-transparent and semi-reflective film layer is provided on the side surface of the first transparent element opposite to the transparent optoelectronic component; and a second transparent element disposed on the side surface of the transparent optoelectronic component opposite to the first transparent element, wherein a reflective film layer is provided on the side surface of the second transparent element opposite to the transparent optoelectronic component.
[0007] The vehicle headlight module of this application embodiment has a first transparent element and a second transparent element respectively disposed on both sides of the transparent optoelectronic component. The first transparent element has a semi-transparent and semi-reflective film layer, and the second transparent element has a reflective film layer. First, the light emitted by the transparent optoelectronic component is incident on the first transparent element. After passing through the semi-transparent and semi-reflective film layer, part of the light is transmitted out, and the other part is reflected. Then, the reflected light passes through the transparent optoelectronic component and the second transparent element in sequence and reaches the reflective film layer. This part of the light is reflected again by the reflective film layer and passes through the transparent optoelectronic component and the first transparent element in sequence before reaching the semi-transparent and semi-reflective film layer again. Based on the above process, the light emitted by the transparent optoelectronic component can be reflected and transmitted multiple times between the semi-transparent and semi-reflective film layer and the reflective film layer. Based on the principle of mirror imaging, a layered virtual image superposition phenomenon is finally formed. This is beneficial to achieving a brilliant lighting effect for the vehicle headlights, thereby improving the vehicle's premium feel and user experience.
[0008] In some embodiments, the reflectivity of the semi-transparent and semi-reflective film layer is greater than or equal to 50% and less than or equal to 70%.
[0009] This setup allows for reasonable control of energy loss with each reflection, resulting in a gradual decrease in the brightness of the superimposed image. With an appropriate number of superimposed images, it presents a visual effect with a strong sense of three-dimensionality and natural transition between light and dark, which in turn helps to achieve a brilliant lighting effect for the headlights, enhancing the vehicle's premium feel and user experience.
[0010] In some embodiments, the transparent optoelectronic component is a transparent display screen, which includes a light-emitting unit, and the light-emitting unit is one of Mini LED (light emitting diode), Micro LED, and OLED (Organic Light Emitting Diode).
[0011] This not only helps to further enhance the visual effect of the headlights' brilliant illumination, but also expands the application scenarios of the headlight modules, integrating image information display into the aesthetics of light and shadow.
[0012] In some embodiments, the surface of the first transparent member facing away from the transparent optoelectronic component is a plane, and the surface of the second transparent member facing away from the transparent optoelectronic component is a plane.
[0013] In this context, the vehicle headlight module of this application achieves a brilliant lighting effect by utilizing the principle of plane mirror reflection imaging. On the one hand, this facilitates the fabrication of the reflective film and the semi-transparent / semi-reflective film; on the other hand, it reduces the processing difficulty of the second transparent component and the first transparent component, thereby lowering costs.
[0014] In some embodiments, the surface of the first transparent element facing away from the transparent optoelectronic component is composed of a plurality of first sub-planes spliced together, and any two adjacent first sub-planes are not coplanar;
[0015] The surface of the second transparent component facing away from the transparent optoelectronic component is composed of several second sub-planes, and any two adjacent second sub-planes are not coplanar.
[0016] Due to the angular differences between different first and second subplanes, light is reflected and transmitted in multiple directions at the semi-transparent and semi-reflective film layer and the reflective film layer, forming a three-dimensional scattering light effect. The light forms a matrix of sparkling light points like crystal, creating an exquisite and textured light and shadow effect, which helps to further enhance the brilliant lighting effect of the lights and improve the vehicle's visual sense of luxury and recognizability.
[0017] In some embodiments, the orthographic projection of the first transparent element on the transparent optoelectronic component coincides with the orthographic projection of the second transparent element on the transparent optoelectronic component, and the number of the second sub-planes is 20 to 120 times the number of the first sub-planes.
[0018] This setup achieves several advantages. First, it balances the lighting effect of the headlight module with manufacturing costs and complexity. Second, fewer first sub-planes allow for wider-spaced main light spots, enhancing brightness; while more second sub-planes, each acting as an independent reflector, cut light into smaller spots, filling the spaces between the main spots with numerous secondary spots. This upgrades the light and shadow effect to a delicate, starry, granular texture, while also improving the sense of spatial depth. Third, adjusting the ratio of first to second sub-planes allows for flexible control of the headlight's lighting effect, enabling different vehicle models to produce lighting effects that match their character. This facilitates rapid adaptation to the design and development of various vehicle models, further reducing development costs and timelines for vehicle headlights.
[0019] In some embodiments, the average thickness of the first transparent element is less than the average thickness of the second transparent element.
[0020] This design offers several advantages. First, it ensures that the light transmittance of the first transparent component is not too low, thus reducing the power consumption of the transparent optoelectronic components and improving heat dissipation in the headlight module to some extent. Second, the thinner first transparent component results in a shallower depth of field for directly transmitted light, forming a clear real image layer. The thicker second transparent component, primarily responsible for cyclic reflection of light, increases the optical path of the reflected light, ensuring a sense of depth and three-dimensionality after the superimposed virtual image, expanding the spatial separation between real and virtual images, and further enhancing the brightness of the lighting effect. Third, it also helps reduce the overall thickness of the headlight module, enabling a more compact structural design. Fourth, as the underlying structure, the greater thickness of the second transparent component allows for a rigid support combination with the transparent optoelectronic components, further improving the strength and reliability of the headlight module.
[0021] In some embodiments, the average thickness of the first transparent element is greater than or equal to 1 mm and less than or equal to 5 mm, and the average thickness of the second transparent element is greater than or equal to 2 mm and less than or equal to 8 mm.
[0022] By limiting the thickness of the first transparent component within the aforementioned range, it is beneficial to improve the frosted soft light effect of the headlight module, and also to improve the reliability and stability of the headlight module. By limiting the thickness of the second transparent component within the aforementioned range, it is beneficial to improve the layering of the light shadows in the headlight module, and also to improve the brightness of the light shadows, achieving a dazzling starlight lighting effect.
[0023] In some embodiments, the average thickness of the first transparent element is greater than or equal to 2 mm and less than or equal to 3 mm, and the average thickness of the second transparent element is greater than or equal to 3 mm and less than or equal to 5 mm.
[0024] In this way, on the one hand, the effect of the frosted soft light of the headlight module can be further improved, as well as the reliability and stability of the headlight module. On the other hand, the sense of layering of the light shadows of the headlight module can be further improved, as well as the brightness of the light shadows, to achieve a dazzling starlight lighting effect.
[0025] Secondly, embodiments of this application provide a vehicle including the headlight module described in the first aspect.
[0026] This design allows the light emitted from the transparent optoelectronic component to undergo multiple reflections and transmissions between the semi-transparent and semi-reflective film layers. Based on the principle of mirror imaging, this ultimately creates a layered, overlapping virtual image phenomenon. This contributes to achieving a dazzling visual effect when the headlights are illuminated, thereby enhancing the vehicle's premium feel and overall 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.
[0046] like Figure 1 As shown, in a first aspect, this application provides a vehicle headlight module 10. The headlight module 10 includes a transparent optoelectronic component 100, a first transparent element 200, and a second transparent element 300. The transparent optoelectronic component 100 is used for emitting and transmitting light. The first transparent element 200 is disposed on one side surface of the transparent optoelectronic component 100, and a semi-transparent and semi-reflective film layer 210 is provided on the side surface of the first transparent element 200 opposite to the transparent optoelectronic component 100. The second transparent element 300 is disposed on the side surface of the transparent optoelectronic component 100 opposite to the first transparent element 200, and a reflective film layer 310 is provided on the side surface of the second transparent element 300 opposite to the transparent optoelectronic component 100.
[0047] The transparent optoelectronic component 100 is a light-emitting structure that is transparent and emits light when energized, while maintaining a certain degree of transparency. The transparent optoelectronic component 100 can be, for example, a transparent display screen as in the prior art, or a light-emitting structure composed of a transparent substrate and a light source; this application does not limit this to any particular type.
[0048] The first transparent component 200 and the second transparent component 300 can be made of materials such as optical glass, polycarbonate (PC), and acrylic (PMMA). The first transparent component 200 and the second transparent component 300 can be connected to the transparent optoelectronic component 100 by various methods such as adhesive bonding and magnetic attraction.
[0049] The semi-transparent and semi-reflective coating 210 refers to an optical coating that can simultaneously achieve light transmission and reflection, while the reflective coating 310 refers to an optical coating that achieves light reflection. Both the semi-transparent and semi-reflective coating 210 and the reflective coating 310 can be formed by processes such as magnetron sputtering and electron beam evaporation.
[0050] The vehicle headlight module 10 of this application embodiment has a first transparent element 200 and a second transparent element 300 respectively disposed on both sides of the transparent optoelectronic component 100. The first transparent element 200 has a semi-transparent and semi-reflective film layer 210, and the second transparent element 300 has a reflective film layer 310. First, the light emitted by the transparent optoelectronic component 100 is incident into the first transparent element 200. After passing through the semi-transparent and semi-reflective film layer 210, part of the light is transmitted out, and the other part is reflected. Then, the reflected light passes through the transparent optoelectronic component 100 and the second transparent element 300 in sequence and reaches the reflective film layer 310. Afterward, this part of the light is reflected again by the reflective film layer 310 and passes through the transparent optoelectronic component 100 and the first transparent element 200 in sequence before reaching the semi-transparent and semi-reflective film layer 210 again. Based on the above process, the light emitted from the transparent optoelectronic component 100 can be reflected and transmitted multiple times between the semi-transparent and semi-reflective film layer 210 and the reflective film layer 310. Based on the principle of mirror imaging, a layered virtual image superimposed phenomenon is finally formed. like Figure 2 As shown, when one of the light sources in the transparent optoelectronic component 100 is lit, it can present a layered, overlapping effect.
[0051] This helps to achieve a dazzling visual effect when the headlights are lit, thereby enhancing the vehicle's premium feel and overall experience.
[0052] Furthermore, since the first transparent element 200 and the second transparent element 300 are directly disposed on opposite sides of the transparent optoelectronic component 100, there is no air layer between them. This reduces light loss and stray light, thereby improving light extraction efficiency. It also reduces the thickness of the headlight module 10, enabling miniaturized and integrated headlight design.
[0053] In some embodiments, the reflectivity of the semi-transparent and semi-reflective film layer 210 is greater than or equal to 50% and less than or equal to 70%.
[0054] If the reflectivity of the semi-transparent and semi-reflective film layer 210 is too low, most of the light will pass directly through the first light-transmitting element 200, resulting in a poor superimposed effect and making it difficult to form a dazzling visual effect. If the reflectivity is too high, the reflected light will be too strong and the transmitted light will be too weak, which may cause the initial emitted light to be too dark. At the same time, the superimposed images will be densely overlapping and the boundaries will be blurred, forming "glare" or "halo".
[0055] In this embodiment, the reflectivity of the semi-transparent and semi-reflective film layer 210 is set in the range of greater than or equal to 50% and less than or equal to 70%. This allows for reasonable control of the energy loss of each reflection, resulting in a gradual decrease in the brightness of the superimposed image. With an appropriate number of superimposed images, a visual effect with a strong sense of three-dimensionality and natural transition between light and dark is presented. This, in turn, helps to achieve a brilliant lighting effect for the vehicle headlights, enhancing the vehicle's premium feel and user experience.
[0056] Optionally, the reflectivity of the semi-transparent and semi-reflective film layer 210 can be, for example, 50%, 55%, 60%, 65%, 70%, etc., and can be flexibly set according to the actual situation.
[0057] In some embodiments, such as Figure 3 As shown, the transparent optoelectronic component 100 is a transparent display screen 110, which includes a light-emitting unit 111, which is one of Mini LED (light emitting diode), Micro LED, or OLED (Organic Light Emitting Diode).
[0058] The transparent display screen 110 combines light transmittance and light emission, and can be used as one implementation of the transparent optoelectronic component 100. Here, Mini LED refers to submillimeter-level LED chips, Micro LED refers to micrometer-level LED chips, and OLED refers to organic light-emitting diodes. Mini LED, Micro LED, and OLED light sources can achieve pixel-level arrangement in the transparent display screen 110.
[0059] The transparent display screen 110 achieves light transmittance and allows for individual control of the brightness of each light-emitting unit 111, thereby enabling point light source display, pixel-level regional image display, and sub-pixel-level image display. For example, the transparent display screen 110 can control the illumination of a portion of individual light-emitting units 111, in which case the headlight module 10 can achieve a ghosting effect of multiple point light sources. As another example, the transparent display screen 110 can control certain light-emitting units 111 to achieve regional image display, in which case a ghosting effect representing image information can be achieved. This not only further enhances the visual effect of the headlights' brilliant illumination but also expands the application scenarios of the headlight module 10, integrating information display into the aesthetics of light and shadow.
[0060] The structure of the transparent display screen 110 varies slightly depending on the type of light-emitting unit 111. For example... Figure 3 As shown, taking a micro LED as an example for the light-emitting unit 111, the transparent display screen 110 typically also includes a transparent substrate 112, a driving electrode 113, and a transparent cover plate 114. The light-emitting unit 111 is electrically connected to the driving electrode 113 and is located between the transparent substrate 112 and the transparent cover plate 114. The transparent substrate 112 and the transparent cover plate 114 can be, for example, rigid transparent glass, or transparent flexible materials such as polyimide (PI), and this application does not limit this. The driving electrode 113 can be made of transparent metal oxides such as indium tin oxide (ITO), oxide semiconductor (IGZO), etc., or it can be made of metal mesh, and this application does not limit this either.
[0061] It should be noted that the above only exemplifies one structure of the micro LED transparent display screen 110 and is not intended to limit the specific structure of the micro LED transparent display screen 110. The transparent display screen 110 can adopt any of the existing transparent display screens 110 that use Mini LED, Micro LED or OLED as the light source.
[0062] In addition, Figure 3 In the diagram, the driving electrode 113 is shown as a layer structure, located on one side of the transparent substrate 112 and between the transparent substrate 112 and the light-emitting unit 111. This is merely to illustrate the film structure of the driving electrode 113 and the transparent substrate 112 for convenience, and is not intended to limit the specific structure in an actual product. It is understood that the driving electrode 113 can have various configurations. For example, the driving electrode 113 can be directly etched into the transparent substrate 112, or the driving electrode 113 can be disposed on the side of the light-emitting unit 111 facing away from the transparent substrate 112, etc. The specific configuration can be flexibly adjusted according to the actual situation.
[0063] like Figure 4 As shown, in some other embodiments, the transparent optoelectronic component 100 does not use a pre-fabricated transparent display screen. Instead, it comprises only a transparent substrate, transparent electrodes, and a light source (Mini LED, Micro LED, or OLED) electrically connected to the transparent electrodes. The transparent optoelectronic component 100 only needs to fulfill the basic functions of emitting and transmitting light. This configuration achieves both a dazzling visual effect from the vehicle headlights and helps reduce the cost of the headlight module 10.
[0064] like Figure 1 As shown, in some embodiments, the surface of the first transparent element 200 facing away from the transparent photoelectric component 100 is flat, and the surface of the second transparent element 300 facing away from the transparent photoelectric component 100 is also flat. In this case, the vehicle headlight module 10 of this application achieves a brilliant lighting effect of the vehicle headlights by using the principle of plane mirror reflection imaging.
[0065] This design, on the one hand, facilitates the preparation of the reflective film layer 310 and the semi-transparent and semi-reflective film layer 210, and on the other hand, reduces the processing difficulty of the second transparent component 300 and the first transparent component 200, thereby reducing costs.
[0066] like Figure 4 , Figure 5 , Figure 6As shown, in some other embodiments, the surface of the first transparent component 200 facing away from the transparent optoelectronic component 100 is formed by splicing together a plurality of first sub-planes 201, and any two adjacent first sub-planes 201 are not coplanar. The surface of the second transparent component 300 facing away from the transparent optoelectronic component 100 is formed by splicing together a plurality of second sub-planes 301, and any two adjacent second sub-planes 301 are not coplanar.
[0067] The complexity of the shape of the surface of the first transparent element 200 facing away from the transparent photoelectric component 100 varies depending on the number of first sub-planes 201. The more first sub-planes 201 there are, the more complex the shape of that surface. Similarly, the complexity of the shape of the surface of the second transparent element 300 facing away from the transparent photoelectric component 100 also varies depending on the number of second sub-planes 301. The more second sub-planes 301 there are, the more complex the shape of that surface.
[0068] like Figure 7 As shown, if the number of first sub-planes 201 is small, 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 polyhedron surface formed by multiple first sub-planes 201 with larger areas. Similarly, if the number of second sub-planes 301 is small, the area of each second sub-plane 301 is large. In this case, the surface of the second transparent element 300 can be regarded as an irregular prism or polyhedron surface formed by multiple second sub-planes 301 with larger areas.
[0069] In other words, when the number of first sub-planes 201 and second sub-planes 301 is small, the two surfaces can form an irregular prism surface. A semi-transparent, semi-reflective film layer 210 is disposed on the prism surface of the first transparent element 200, and a reflective film layer 310 is disposed on the prism surface of the second transparent element 300. Compared to the aforementioned embodiments (such as...), Figure 1 In the case of setting the two surfaces as a whole plane, although the structural complexity of the first transparent element 200 and the second transparent element 300 is increased, the surface transforms the planar optical effect into a multi-angle composite light field. Each first sub-plane 201 and second sub-plane 301 can form an independent optical micro-region, resulting in a discrete distribution of light scattering and reflection directions.
[0070] In this situation, due to the angular differences between different first sub-planes 201 and different second sub-planes 301, light is reflected and transmitted in multiple directions at the semi-transparent and semi-reflective film layer 210 and the reflective film layer 310, forming a three-dimensional diffused light effect, which helps to further enhance the brilliance of the lighting. Please refer to... Figure 8 When a certain light source is lit, and Figure 2 In comparison, the twinkling effect of the headlights has been further enhanced.
[0071] like Figure 9 As shown, if the number of first sub-planes 201 is large, the area of each first sub-plane 201 is small. In this case, the surface of the first transparent element 200 can be regarded as an irregular three-dimensional crystal pattern formed by multiple tiny first sub-planes 201. Similarly, if the number of second sub-planes 301 is large, the area of each second sub-plane 301 is small. In this case, the surface of the second transparent element 300 can be regarded as an irregular three-dimensional crystal pattern formed by multiple tiny second sub-planes 301.
[0072] In other words, when there are a large number of first sub-planes 201 and second sub-planes 301, the two surfaces can form a three-dimensional crystal pattern. A semi-transparent and semi-reflective film layer 210 is disposed on the three-dimensional crystal pattern surface of the first transparent component 200, and a reflective film layer 310 is disposed on the three-dimensional crystal pattern surface of the second transparent component 300. It can be understood that the structural complexity of the first transparent component 200 and the second transparent component 300 is further increased.
[0073] In this configuration, numerous tiny first sub-planes 201 and second sub-planes 301 act like countless miniature prisms, allowing light to undergo more subtle diffuse reflection and / or transmission on the surfaces of the semi-transparent and semi-reflective film layer 210 and the reflective film layer 310. This creates a crystal-like matrix of sparkling light points, producing a refined and textured light and shadow effect, making the lighting more visually appealing and unique, thereby maximizing the vehicle's perceived sophistication and recognizability. Please refer to... Figure 10 When a certain light source is lit, and Figure 2 and Figure 8 In comparison, the twinkling effect of the headlights is further enhanced, like sparkling crystals.
[0074] like Figure 4 , Figure 5 and Figure 6 As shown, in a specific embodiment, the orthographic projection of the first transparent element 200 on the transparent optoelectronic component 100 coincides with the orthographic projection of the second transparent element 300 on the transparent optoelectronic component 100, and the number of second sub-planes 301 is 20 to 120 times the number of first sub-planes 201.
[0075] With this configuration, firstly, the first transparent component 200 is easier and cheaper to process, while the numerous tiny second sub-planes 301 of the second transparent component 300 can achieve more detailed diffuse reflection, thus achieving a more dazzling crystal lighting effect compared to planar reflection. This balance can be achieved between the lighting effect of the headlight module 10 and the processing cost and difficulty.
[0076] Secondly, the high-density micro-facet structure of the second transparent element 300 complements the sparse facet structure of the first transparent element 200. The former dominates the refined reflection of light, while the latter constrains the propagation direction of transmitted light. Fewer first sub-planes 201 can form wider-spaced main light spots, which can improve the illumination brightness; while in the more numerous second sub-planes 301, each second sub-plane 301 acts as an independent reflection unit, which can cut the light into smaller light spots and fill a large number of secondary light spots between the main light spots, upgrading the light and shadow effect to a delicate, starry, granular texture, while also enhancing the spatial depth of the light and shadow.
[0077] Thirdly, by adjusting the ratio of the number of the first subplane 201 to the number of the second subplane 301, the lighting effect of the headlights can be flexibly controlled, so that different models can produce lighting effects that match the vehicle's character, quickly adapting to the design and development of different models, and thus helping to reduce the development cost and cycle of vehicle headlights.
[0078] Optionally, the number of second subplanes 301 can be, for example, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, or 120 times the number of first subplanes 201, and can be flexibly set according to the actual situation. For example, if there are 20 first subplanes 201, the number of second subplanes 301 may be no less than 1000, and can also be flexibly set according to the actual situation.
[0079] like Figure 1 As shown, in some embodiments, the average thickness of the first transparent element 200 is less than the average thickness of the second transparent element 300. This configuration has several advantages. First, since the first transparent element 200 transmits light in addition to reflecting it, a thinner average thickness ensures that the light transmittance of the first transparent element 200 is not too low, thus reducing the power consumption of the transparent optoelectronic component 100 and improving the heat dissipation of the headlight module 10 to some extent. Second, the thinner first transparent element 200 results in a shallower depth of field for directly transmitted light, forming a clear real image layer. The second transparent element 300, primarily responsible for the cyclic reflection of light, has a thicker thickness that increases the optical path of the reflected light, ensuring a sense of depth and three-dimensionality after the superimposed virtual image, expanding the spatial separation between the virtual and real images, and further enhancing the brilliance of the lighting effect. Third, the different thicknesses of the first transparent element 200 and the second transparent element 300 also help reduce the overall thickness of the headlight module 10, achieving a compact structural design for the headlight. Fourthly, the second transparent component 300, as the bottom layer structure, has a relatively thick thickness that can form a rigid support combination with the transparent optoelectronic component 100, which in turn helps to improve the strength and reliability of the vehicle lamp module 10.
[0080] In some embodiments, the average thickness of the first transparent element 200 is greater than or equal to 1 mm and less than or equal to 5 mm. If the thickness of the first transparent element 200 is too small, the scattering of the semi-transparent and semi-reflective film layer 210 will be insufficient, and the light from the transparent optoelectronic component 100 will be too direct, losing the effect of frosted soft light. If the thickness of the first transparent element 200 is too large, the light transmittance of the first transparent element 200 will be too low, and the brightness of the light can only be improved by increasing the power consumption of the transparent optoelectronic component 100, which will cause heat dissipation problems in the vehicle headlight module 10.
[0081] By limiting the thickness of the first transparent element 200 within the aforementioned range, it is beneficial to improve the effect of the frosted soft light of the headlight module 10, and also to improve the reliability and stability of the headlight module 10.
[0082] Preferably, in a specific embodiment, the average thickness of the first transparent element 200 is greater than or equal to 2 mm and less than or equal to 3 mm. For example, it is 2 mm, 2.5 mm, or 3 mm. This can further improve the frosted soft light effect of the headlight module 10, as well as further improve the reliability and stability of the headlight module 10.
[0083] In some embodiments, the average thickness of the second transparent element 300 is greater than or equal to 2 mm and less than or equal to 8 mm. If the thickness of the second transparent element 300 is too small, the reflected image of the reflective film layer 310 will be too close to the light-emitting surface of the headlight module 10, causing the superimposed image effect to degenerate into a planar ghost image with insufficient layering. If the thickness of the second transparent element 300 is too large, the reflected light path of the second transparent element 300 will become longer, and the reflected light will be severely attenuated, resulting in a darkened image and poor lighting effect. By limiting the thickness of the second transparent element 300 within the above range, it is beneficial to improve the layering of the light superimposed image of the headlight module 10 on the one hand, and to improve the brightness of the superimposed image on the other hand, achieving a dazzling starlight lighting effect.
[0084] Preferably, in a specific embodiment, the average thickness of the second transparent element 300 is greater than or equal to 3mm and less than or equal to 5mm. For example, it is 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. In this way, the layering of the light shadow of the headlight module 10 can be further improved, as well as the brightness of the light shadow, to achieve a dazzling starlight lighting effect.
[0085] Secondly, embodiments of this application provide a vehicle including the headlight module 10 described in the first aspect.
[0086] This configuration allows the emitted light from the transparent optoelectronic component 100 to undergo multiple reflections and transmissions between the semi-transparent and semi-reflective film layer 210 and the reflective film layer 310. Based on the principle of mirror imaging, this ultimately creates a layered, overlapping virtual image phenomenon. This facilitates a more dazzling visual effect when the vehicle lights are illuminated, thereby enhancing the vehicle's premium feel and overall experience.
[0087] 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.
