Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle decoration technology, and in particular to an ambient lighting assembly and vehicle. Background Technology
[0002] With the rapid development of the automotive industry, an increasing number of cars are equipped with ambient lighting assemblies to enhance the aesthetics of the interior by emitting ambient light patterns. These assemblies typically consist of glass, light guides, LEDs, and ambient light patterns. The patterns are positioned on the inner or outer surface of the glass. Light emitted from the LEDs is refracted through the light guides onto the glass and then reflected back into the vehicle by the ambient light patterns, creating the ambient lighting effect. However, these ambient lighting assemblies suffer from issues such as localized overbrightness in certain areas and uneven brightness, which negatively impacts their overall illumination. Summary of the Invention
[0003] Therefore, it is necessary to address the problem of uneven brightness and localized over-brightness in ambient lighting assemblies in related technologies by providing an ambient lighting assembly and vehicle.
[0004] An ambient lighting assembly, comprising:
[0005] A light-transmitting substrate having a first surface and a second surface arranged opposite to each other;
[0006] A pattern layer is disposed on the light-transmitting substrate;
[0007] A light source and a light guide are disposed on one side of the first surface of the light-transmitting substrate. The light emitted by the light source can be conducted by the light guide and projected onto the light-transmitting substrate, and reflected by the pattern layer toward the side of the first surface.
[0008] A first light-shielding layer is disposed on a first surface of the light-transmitting substrate, and the first light-shielding layer is disposed around the projection of the light-emitting light source, the light guide and the pattern layer on the first surface;
[0009] In the projection on the first surface, the first light-shielding layer includes a corner light-shielding portion located between the pattern layer and the light guide. The corner light-shielding portion has an arcuate profile near the pattern layer and a straight profile near the light guide. The angle between the tangent of the arcuate profile near the endpoint of the straight profile and the straight profile is less than or equal to 30°.
[0010] The aforementioned ambient lighting assembly ensures that, in the projection onto the first surface, the angle between the tangent of the arc contour near the endpoint of the straight contour and the straight contour is less than or equal to 30°. This constrains the coverage area of the first light-shielding layer between the light guide and the pattern layer, effectively blocking the corner area between the light guide and the pattern layer. This prevents brightening or the appearance of bright and dark stripes, halos, etc., in the corner area, thus improving the uniformity and effect of the ambient lighting assembly. Simultaneously, the coverage area of the first light-shielding layer between the light guide and the pattern layer is not excessive, allowing light to be smoothly conducted within the light-transmitting substrate 21 from the hollowed-out area formed by the first light-shielding layer between the light guide and the pattern layer to the area where the pattern layer is located, reducing the impact of the first light-shielding layer on the brightness of the ambient lighting assembly.
[0011] In one embodiment, in the projection onto the first surface, the tangent of the arcuate profile near the endpoint of the straight profile is parallel to the straight profile.
[0012] In one embodiment, in the projection on the first surface, the corner shading portion further includes a transition profile connecting the arcuate profile and the straight profile, the angle between the transition profile and the straight profile, and the angle between the transition profile and the tangent of the arcuate profile near the endpoint of the straight profile, which is greater than the angle between the tangent of the arcuate profile near the endpoint of the straight profile and the straight profile.
[0013] In one embodiment, in the projection on the first surface, the first light-shielding layer includes two corner light-shielding portions, which are spaced apart and have opposite transition contours.
[0014] In one embodiment, the transition profile is perpendicular to the straight profile; or,
[0015] In the direction along the straight profile toward the other corner shading portion, the transition profile is inclined relative to the straight profile toward the side where the arc profile is located.
[0016] In one embodiment, in the projection on the first surface, the light guide is located on the side of the corner light-shielding portion away from the pattern layer, and the light source is located on the side of the light guide opposite to the corner light-shielding portion. The light emitted by the light source can be transmitted through the light guide and then enter the light-transmitting substrate, and then be transmitted in the light-transmitting substrate in the direction of the light guide pointing to the pattern layer.
[0017] In one embodiment, the ambient light assembly further includes a light shield disposed on a first surface of the light-transmitting substrate and covering the light source and the light guide. In the projection on the first surface, at least a portion of the arcuate contour near the light guide is covered by the light shield.
[0018] In one embodiment, in the projection on the first surface, the shortest distance between the endpoint of the arcuate profile near the straight profile and the edge profile of the light shield is greater than or equal to 2.5 mm.
[0019] In one embodiment, the light-transmitting substrate includes a first glass and a second glass stacked together. The first glass forms a first surface on the side facing away from the second glass, and the second glass forms a second surface on the side facing away from the first glass. The pattern layer is disposed between the first glass and the second glass, or on the first glass, or on the first surface. The ambient light assembly also includes a second light-shielding layer, which surrounds the pattern layer in the projection on the first surface.
[0020] In one embodiment, the ambient light assembly further includes a transition light-shielding structure, which is disposed in the same layer as the second light-shielding layer. In the projection on the first surface, the transition light-shielding structure is located between the pattern layer and the second light-shielding layer, and the inner contour of the transition light-shielding structure is adapted to the shape of the outer contour of the pattern layer.
[0021] In one embodiment, the ambient light assembly further includes an adhesive layer stacked between the first glass and the second glass, a second light-shielding layer and the transition light-shielding structure disposed between the second glass and the adhesive layer, and a pattern layer disposed between the first glass and the adhesive layer.
[0022] A vehicle includes a body and an ambient lighting assembly as described in any of the above embodiments, the ambient lighting assembly being disposed on the vehicle body. Attached Figure Description

Detailed Implementation
[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0041] The ambient lighting assembly in related technologies includes components such as glass, a light guide, LED chips, an ambient lighting pattern, and a light-shielding ink layer. The ambient lighting pattern is set on the glass, and the light emitted by the LED chips can be conducted by the light guide and projected onto the glass, where it is reflected by the ambient lighting pattern to create the ambient lighting effect. The light-shielding ink layer is set on the glass and surrounds the ambient lighting pattern. The light on the area of the glass covered by the light-shielding ink layer is blocked by the ink layer and cannot be emitted, thereby preventing light from emanating from areas outside the ambient lighting pattern. However, in the ambient lighting assembly of related technologies, when the outline of the ambient lighting pattern near the light guide is curved, the light-shielding ink layer usually does not cover the corner area between the curved outline of the ambient lighting pattern and the light guide. This causes the corner area between the curved outline and the light guide to shine, or produces phenomena such as bright and dark stripes or halos, resulting in uneven light emission from the ambient lighting assembly and affecting the lighting effect.
[0042] To address the aforementioned issues, this application provides an ambient lighting assembly and a vehicle.
[0043] Please see Figure 1 and Figure 2 The ambient lighting assembly 20 provided in this application can be applied to a vehicle 10, which also includes a body 11, and the ambient lighting assembly 20 is mounted on the body 11. The ambient lighting assembly 20 can be used to emit specific luminous patterns towards the interior of the vehicle to create an ambient lighting effect, enhancing the aesthetics of the interior. The vehicle 10 provided in this application includes, but is not limited to, any type of vehicle such as a sedan, SUV, multi-purpose commercial vehicle, sports car, and van. The ambient lighting assembly 20 includes, but is not limited to, the side windows, sunroof, and rear window of the vehicle 10. Figure 1 The side window is used as an example.
[0044] refer to Figure 3 and Figure 4As shown, in some embodiments, the ambient lighting assembly 20 includes a light-transmitting substrate 21, a pattern layer 22, a light-emitting light source 23, a light guide 24, and a first light-shielding layer 25. The material of the light-transmitting substrate 21 includes, but is not limited to, light-transmitting materials such as glass. The light-transmitting substrate 21 has a first surface 2111 and a second surface 2121 arranged opposite to each other. When the ambient lighting assembly 20 is installed on the vehicle body 11, the first surface 2111 can face the inside of the vehicle, and the second surface 2121 can face the outside of the vehicle. The pattern layer 22 is disposed on the light-transmitting substrate 21, and the light-emitting light source 23 and the light guide 24 are disposed on the side where the first surface 2111 of the light-transmitting substrate 21 is located. The light-emitting light source 23 is used to emit light towards the light guide 24, and the light guide 24 is used to conduct the light emitted by the light-emitting light source 23 to the light-transmitting substrate 21 through refraction or other means, so that the light is reflected by the pattern layer 22 towards the side where the first surface 2111 is located within the light-transmitting substrate 21, that is, reflected towards the inside of the vehicle to form an ambient lighting effect.
[0045] The first light-shielding layer 25 is disposed on the first surface 2111 of the light-transmitting substrate 21. The first light-shielding layer 25 surrounds the light-emitting light source 23, the light guide 24, and the projection of the pattern layer 22 onto the first surface 2111. The material of the first light-shielding layer 25 includes, but is not limited to, light-shielding materials such as ink. The first light-shielding layer 25 can block light and prevent light from escaping from the area where the first light-shielding layer 25 is located from the light-transmitting substrate 21, thereby improving the pattern light-emitting effect emitted from the area where the pattern layer 22 is located.
[0046] Furthermore, combined Figure 5 and Figure 6 As shown, in some embodiments, in the projection on the first surface 2111, the first light-shielding layer 25 includes a corner light-shielding portion 251 located between the pattern layer 22 and the light guide 24. The corner light-shielding portion 251 has an arcuate profile 253 close to the pattern layer 22. The corner light-shielding portion 251 covers at least a portion of the corner area between the arcuate profile 253 of the pattern layer 22 and the light guide 24 where the pattern layer 22 is not located. The corner light-shielding portion 251 has a straight profile 254 close to the light guide 24, i.e., away from the arcuate profile 253. The arcuate profile 253 is close to the endpoint of the straight profile 254. Figure 5 Endpoint A shown and Figure 6 The angle between the tangent at endpoint B) and the straight profile 254 shown is less than or equal to 30°. (Combined) Figure 7 As shown, Figure 7 This diagram illustrates one of the corner light-blocking sections, 251. Figure 7 The angle H shown is the angle between the tangent (straight line I) of the arc profile 253 of the light-shielding part 251 near the endpoint of the straight profile 254 and the straight profile 254 (extension line).
[0047] It is understandable that defining the angle between the tangents of the straight profile 254 and the arc profile 253 near the endpoint of the straight profile 254 can constrain the coverage area of the corner light-shielding portion 251 between the light guide 24 and the pattern layer 22. For example, when the straight profile 254 is parallel to the side of the light guide 24 facing the pattern layer 22 ( Figure 5 When the surface shown is C), the corner light-shielding portion 251 of the first light-shielding layer 25 extends between the light guide 24 and the pattern layer 22 to a position where the angle between the tangent of the arc contour 253 of the pattern layer 22 and the side of the light guide 24 facing the pattern layer 22 is less than or equal to 30°.
[0048] Combination Figure 2 As shown, in some embodiments, in the projection on the first surface 2111, there are two arc contours 253 transitioning between the pattern layer 22 and a light guide 24. The two arc contours 253 can respectively correspond to the two ends of the light guide 24, thus there are two corner regions between the light guide 24 and the pattern layer 22. The first light-shielding layer 25 includes two corner light-shielding portions 251, and the arc contours 253 of the two corner light-shielding portions 251 are close to the pattern layer. It can be understood that when the coverage area of the corner light-shielding portions 251 in the corner region is too small, for example, when the distance between the two corner light-shielding portions 251 is too large, it is easy for some corner regions to not be blocked by the first light-shielding layer 25 and to shine. When the coverage area of the corner light-shielding portions 251 in the corner region is too large, for example, when the distance between the two corner light-shielding portions 251 is too small, the corner light-shielding portions 251 are easy to absorb the light transmitted from the area where the light guide 24 is located to the area where the pattern layer 22 is located on the light-transmitting substrate 21, affecting the luminous brightness of the ambient light assembly 20.
[0049] In some embodiments, the light source 23 is located on the side of the light guide 24 facing away from the corner light-shielding portion 251. The light emitted by the light source 23 can be transmitted through the light guide 24 and enter the light-transmitting substrate 21 from the first surface 2111. Then, it is transmitted within the light-transmitting substrate 21 in the direction of the light guide 24 pointing towards the pattern layer 22, thereby transmitting light from the location of the light guide 24 to the location of the pattern layer 22 to form an ambient light pattern. In this way, by utilizing the light homogenization effect of the light guide 24 and the light transmission and dispersion effect within the light-transmitting substrate 21, the uniformity of the ambient light pattern light emitted by the ambient light assembly 20 is improved, thus enhancing the ambient light effect.
[0050] Therefore, the ambient light assembly 20 provided in some embodiments of this application makes the angle between the tangent of the arc contour 253 near the endpoint of the straight contour 254 and the straight contour 254 in the projection on the first surface 2111 less than or equal to 30°. This can constrain the coverage area of the first light-shielding layer 25 between the light guide 24 and the pattern layer 22, so that the first light-shielding layer 25 has sufficient coverage in the corner area between the arc contour 253 and the light guide 24. This allows the first light-shielding layer 25 to effectively block the corner area between the light guide 24 and the pattern layer 22, and to block the brightening or the appearance of bright and dark stripes, halos, etc. in the corner area, which is beneficial to improving the light emission uniformity and light emission effect of the ambient light assembly 20. At the same time, the coverage area of the first light-shielding layer 25 between the light guide 24 and the pattern layer 22 will not be too large, so that light can be smoothly transmitted from the hollow area formed by the first light-shielding layer 25 between the light guide 24 and the pattern layer 22 to the area where the pattern layer 22 is located within the light-transmitting substrate 21, thereby reducing the impact of the first light-shielding layer 25 on the luminous brightness of the ambient light assembly 20.
[0051] In some embodiments, in the projection on the first surface 2111, the tangent of the arc contour 253 near the endpoint of the straight contour 254 is parallel to the straight contour 254, that is, parallel to the side of the light guide 24 facing the pattern layer 22. It is understood that, taking the position where the tangent of the arc contour 253 near the endpoint of the straight contour 254 is parallel to the side of the light guide 24 facing the pattern layer 22 as a reference, the inner corner area is very small, and the propagation requirement of light from the light guide 24 to the pattern layer 22 is large, while the area of the outer corner area increases rapidly. Therefore, setting the tangent of the endpoint of the arc contour 253 to be exactly parallel to the straight contour 254 and the side of the light guide 24 facing the pattern layer 22 allows the corner light-shielding portion 251 to effectively block the brightening phenomenon in the corner area between the light guide 24 and the pattern layer 22, and also makes it less likely to affect the propagation of light between the light guide 24 and the pattern layer 22, effectively improving the luminous effect of the ambient light assembly 20.
[0052] In some embodiments, in the projection on the first surface 2111, the corner shading portion 251 further includes a transition profile 255 connecting the arc profile 253 and the straight profile 254. The transition profile 255 can be a straight line. The angle between the transition profile 255 and the straight profile 254, and the angle between the transition profile 255 and the tangent of the arc profile 253 near the endpoint of the straight profile 254, are both greater than the angle between the tangent of the arc profile 253 near the endpoint of the straight profile 254 and the straight profile 254.
[0053] Understandably, compared to related technologies, the ambient light assembly 20 provided in this application increases the coverage area of the first light-shielding layer 25 in the corner region, i.e., increases the length of the straight outline 254. Based on this, if the arc outline 253 is directly connected to the straight outline 254, it can easily cause a sudden change in the curvature of the portion of the arc outline 253 near the straight outline 254, affecting the contour coordination of the pattern layer 22 and thus impacting the appearance of the ambient light assembly 20. Therefore, by adding a transition outline 255 between the arc outline 253 and the straight outline 254, and through the angular transition between the transition outline 255 and the arc outline 253, as well as between the transition outline 255 and the straight outline 254, the sudden change in the curvature of the arc outline 253 can be avoided, making the overall outline of the pattern layer 22 more harmonious and improving the appearance of the ambient light assembly 20.
[0054] When the first light-shielding layer 25 includes two corner light-shielding portions 251, the two corner light-shielding portions 251 are arranged at intervals, and the transition contours 255 of the two corner light-shielding portions 251 are opposite to each other. The area where the pattern layer 22 is projected on the first surface 2111 can present a square area with rounded corners at the four corners.
[0055] refer to Figure 5 and Figure 6 As shown, in some embodiments, the transition contour 255 is perpendicular to the straight contour 254. Therefore, by adjusting the length of the transition contour 255, the curvature difference at various points of the arc contour 253 can be prevented from being too large, which helps improve the overall aesthetic harmony of the ambient lighting assembly 20. In other embodiments, the transition contour 255 may also be inclined to the straight contour 254, and in the direction along one of the straight contours 254 away from the other corner light-shielding portion 251, the transition contour 255 is inclined relative to the straight contour 254 towards the side where the arc contour 253 is located. This allows for a smoother angular transition between the arc contour 253, the transition contour 255, and the straight contour 254, further enhancing the overall aesthetic harmony of the ambient lighting assembly 20.
[0056] In some embodiments, in the projection on the first surface 2111, the light guide 24 is located on the side of the two corner light-shielding portions 251 away from the pattern layer 22, the transition contours 255 of the two corner light-shielding portions 251 are opposite each other, and the first light-shielding layer 25 is partially hollowed out between the two transition contours 255. The light guide 24 can reflect the light emitted by the light-emitting light source 23 toward the side where the first surface 2111 is located. The light enters the light-transmitting substrate 21 from the first surface 2111 at the light guide 24, and is transmitted to the pattern layer 22 by reflection within the light-transmitting substrate 21. The light guide 24 can homogenize the light emitted by the light-emitting light source 23, improve the uniformity of the light incident on the light-transmitting substrate 21, thereby improving the ambient lighting effect.
[0057] The specific configuration of the light guide 24 is not limited, as long as it can homogenize and conduct the light emitted by the light source 23 into the light-transmitting substrate 21. In the accompanying drawings of this application, a light guide column is used as an example of the light guide 24, and the material of the light guide 24 includes, but is not limited to, polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene (PS), etc. In some other embodiments, the light guide 24 may also be a grating structure layer disposed on the first surface 2111, which conducts the light emitted by the light source 23 into the light-transmitting substrate 21 by means of diffraction or other effects.
[0058] In some embodiments, the ambient light assembly 20 further includes a light shield 26, which is disposed on the first surface 2111 of the light-transmitting substrate 21 and covers the light-emitting source 23 and the light guide 24. For example, the light shield 26 is disposed on the first surface 2111 and forms a receiving space with the light-transmitting substrate 21, and the light-emitting source 23 and the light guide 24 are disposed within the receiving space and fixed to the first surface 2111 of the light-transmitting substrate 21. The light shield 26 can seal and protect the light-emitting source 23 and the light guide 24 and shield their appearance.
[0059] Further, refer to Figure 4 As shown, in some embodiments, in the projection on the first surface 2111, at least a portion of the arcuate contour 253 near the light guide 24 is covered by the light shield 26. Thus, the light shield 26 can shield the transition between the arcuate contour 253, the transition contour 255, and the straight contour 254, thereby shielding the corners of the contour lines so that the corners are not exposed, which helps to improve the appearance harmony of the ambient light assembly 20.
[0060] In some embodiments, in the projection onto the first surface 2111, the shortest distance between the endpoint of the arcuate profile 253 and the edge profile of the light shield 26 is (e.g., the distance between the endpoint of the straight profile 254 and the edge profile of the light shield 26). Figure 4 The distance D shown is greater than or equal to 2.5mm. For example, the distance D can be exactly equal to 2.5mm, so that the corners of the outline can be effectively blocked by the light shield 26, improving the appearance coordination of the ambient light assembly 20.
[0061] refer to Figure 8 and Figure 9As shown, in some embodiments, the hollowed-out area of the first light-shielding layer 25 forms a mounting groove 252. The projections of the light guide 24 and the light source 23 on the first surface 2111 fall into the mounting groove 252. The mounting groove 252 provides mounting space for the light guide 24 and the light source 23, preventing the first light-shielding layer 25 from blocking the light from the light guide 24 from being emitted into the light-transmitting substrate 21. In addition to the mounting groove 252, the shape and size of the remaining hollowed-out area of the first light-shielding layer 25 can be adapted to the projection of the pattern layer 22 on the first surface 2111 to effectively block light from emanating from areas outside the pattern layer 22, thereby improving the luminous effect and aesthetic harmony of the ambient light assembly 20.
[0062] In some embodiments, the light-transmitting substrate 21 may be a single layer of glass, and the pattern layer 22 may be disposed on either the first surface 2111 or the second surface 2121, or disposed on the inner side of the light-transmitting substrate 21.
[0063] refer to Figure 3 and Figure 4 As shown, in some embodiments, the light-transmitting substrate 21 can also be multilayer glass. Figure 3 and Figure 4 Taking a translucent substrate 21 as an example of double-layered glass, the translucent substrate 21 includes a first glass 211 and a second glass 212 stacked together. The side of the first glass 211 facing away from the second glass 212 forms a first surface 2111, and the side of the second glass 212 facing away from the first glass 211 forms a second surface 2121. A pattern layer 22 is disposed between the first glass 211 and the second glass 212. The pattern layer 22 can be disposed on one of the two opposing surfaces of the first glass 211 and the second glass 212. The first glass 211 and the second glass 212 can also be bonded together by any suitable adhesive layer 213, such as optical adhesive or ethylene-vinyl acetate copolymer (EVA). The pattern layer 22 can also be disposed on the adhesive layer 213 between the first glass 211 and the second glass 212. With this configuration, the double-layered glass of the translucent substrate 21 can provide protection for the pattern layer 22, making the arrangement of the pattern layer 22 more stable and reliable.
[0064] Understandably, the light guide 24 has a light-incident surface 241 opposite to the light-emitting source 23, a first side surface 242 facing away from the light-incident surface 241, and a third surface 243 facing the first glass 211. The light emitted by the light-emitting source 23 can enter the light guide 24 from the light-incident surface 241. After refraction by the light guide 24, the light can exit from the third surface 243 into the first glass 211 and directly hit the pattern layer 22, or be conducted to the pattern layer 22 after multiple reflections within the first glass 211. Alternatively, the light can exit from the third surface 243 of the light guide 24 into the first glass 211 and directly hit the pattern layer 22, or be conducted to the pattern layer 22 after multiple reflections within the first glass 211.
[0065] refer to Figure 3 and Figure 10 As shown, in some embodiments, the ambient light assembly 20 further includes a second light-shielding layer 27 disposed on the same layer as the pattern layer 22 and surrounding the pattern layer 22. The second light-shielding layer 27 can shield the light source 23 and the light guide 24, so that the light source 23 and the light guide 24 are not exposed on the second surface 2121 side of the light-transmitting substrate 21. At the same time, it helps to prevent light from escaping from the area of the second glass 212 that corresponds to the pattern layer 22, which helps to improve the appearance integrity and luminous effect of the ambient light assembly 20.
[0066] In some embodiments, the ambient light assembly 20 further includes a transition light-shielding structure 28 disposed on the same layer as the pattern layer 22 and the second light-shielding layer 27, and located between the pattern layer 22 and the second light-shielding layer 27. The transition light-shielding structure 28 can be a dotted ink structure with irregular texture. The transition light-shielding structure 28 can scatter and refract light, causing the light to propagate in different directions, thereby dispersing the concentrated light. This helps to make the light of the ambient light pattern more uniform and soft, avoid obvious differences in brightness and darkness, improve the visual experience, and at the same time add a sense of layering and three-dimensionality to the luminous effect and appearance. It also helps to cover up structural flaws or splicing marks such as outlines, and improve the integrity of the appearance.
[0067] In some embodiments, in the projection on the first surface 2111, the inner contour of the transition light-shielding structure 28 is adapted to the shape of the outer contour of the pattern layer 22, while the portion of the arc contour 253 of the corner light-shielding portion 251 that is farther from the transition contour 255 can be adapted to the outer contour of the transition light-shielding structure 28. Due to the arrangement of the straight contour 254 and the transition contour 255, the curvature difference between the portion of the arc contour 253 that is closer to the transition contour 255 and the inner contour of the second light-shielding layer 27 and the outer contour of the transition light-shielding structure 28 will not be too large. It can be understood that by setting the transition contour 255, while extending the length of the straight contour 254 so that the corner light-shielding portion 251 effectively shields the corner area between the light guide 24 and the pattern layer 22, the curvature of the arc contour 253 will not change abruptly, so that the arc contour 253 can be adapted to or close to the curvature of the inner contour of the transition light-shielding structure 28, effectively improving the appearance coordination of the ambient light assembly 20.
[0068] Please see again. Figure 6 In some embodiments, in the projection of the first surface 2111, the outer contour of the pattern layer 22 connects with the inner contour of the transition light-shielding structure 28, for example... Figure 6 The outline J shown is the boundary line between the outer outline of the pattern layer 22 and the inner outline of the transition light-shielding structure 28. The outer outline of the transition light-shielding structure 28 is connected to the inner outline of the second light-shielding layer 27, for example... Figure 6 The outline K shown is the boundary line between the transition light-shielding structure 28 and the second light-shielding layer 27. The arcuate outline 253 of the corner light-shielding portion 251 can be understood as part of the inner outline of the first light-shielding layer 25. Figure 6 As can be seen, the curvature of the outlines of the pattern layer 22, the transition light-shielding structure 28, and the second light-shielding layer 27 is roughly compatible, allowing the transition light-shielding structure 28 and the second light-shielding layer 27 to work together to effectively block areas outside the pattern layer 22, while improving the overall appearance harmony of the ambient light assembly 20. The portion of the arc contour 253 can be adapted to the inner contour of the second light-shielding layer 27. The curvature of the portion of the arc contour 253 near the straight contour 254 can differ from the inner contour of the second light-shielding layer 27. Due to the straight contour 254, the curvature of the portion of the arc contour 253 near the straight contour 254 will not differ too much from the curvature of the second light-shielding layer 27 and the transition light-shielding structure 28, which helps to improve the overall appearance harmony of the ambient light assembly 20.
[0069] Of course, the arrangement of the second light-shielding layer 27, the transition light-shielding structure 28 and the pattern layer 22 is not limited to the above description. When an adhesive layer 213 is provided between the first glass 211 and the second glass 212, the second light-shielding layer 27 and the transition light-shielding structure 28 can be provided on either side of the adhesive layer 213 opposite to each other. The pattern layer 22 can be provided between the first glass 211 and the second glass 212 on either side of the adhesive layer 213 opposite to each other. Alternatively, the pattern layer 22 can also be provided inside the first glass 211, for example, formed by a shape or pattern provided inside the first glass 211.
[0070] Furthermore, in some embodiments, the second light-shielding layer 27 and the transition light-shielding structure 28 are disposed between the second glass 212 and the adhesive layer 213, the pattern layer 22 is disposed between the adhesive layer 213 and the first glass 211, and the first light-shielding layer 25 is disposed on the first surface 2111 of the first glass 211. Thus, the second light-shielding layer 27 and the first light-shielding layer 25 can jointly provide effective shielding for areas outside the pattern layer 22 on opposite sides of the pattern layer 22, enhancing the ambient lighting effect. Simultaneously, the distribution of each layer is more rational, which is beneficial for optimizing the structural layout and manufacturing process of the ambient lighting assembly 20, making it less likely for the formation processes of each layer to interfere with each other. This reduces the manufacturing difficulty of the ambient lighting assembly 20 while improving its structural reliability.
[0071] refer to Figure 5 and Figure 8 As shown, in some embodiments, in the projection on the first surface 2111, the first light-shielding layer 25 also has a contour line located on the side of the light guide 24 opposite to the straight contour 254, for example... Figure 8 The outline E shown is positioned such that the distance between the outline E and the straight outline 254 is greater than the width of the light guide 24. This ensures that the first light-shielding layer 25 does not cover the light guide 24, preventing the first light-shielding layer 25 from affecting the light emitted from the light guide 24 to the light-transmitting substrate 21, thereby improving the light utilization efficiency of the ambient light assembly 20.
[0072] It should be noted that in this application, the first light-shielding layer 25, the second light-shielding layer 27 and the transition light-shielding structure 28 can all be light-shielding materials such as ink layers disposed on the light-transmitting substrate 21, and the pattern layer 22 can be an ink material disposed on the light-transmitting substrate 21 with a specific distribution pattern. The specific distribution pattern of the pattern layer 22 can be designed according to the ambient light luminous effect, and is not limited in this application.
[0073] The light source 23 includes, but is not limited to, LED beads, and the light guide 24 includes, but is not limited to, acrylic, polycarbonate, or any suitable light guide material. The light guide 24 can be strip-shaped, and multiple light sources 23 can be provided. These multiple light sources 23 can be arranged sequentially and at intervals along the length of the light guide 24 to achieve a uniform and high-brightness light emission effect. (Reference) Figure 2 and Figure 8 As shown, in some embodiments, the ambient light assembly 20 may be provided with two sets of light guides 24 and light sources 23. The two sets of light guides 24 are respectively provided on opposite sides of the pattern layer 22. Each light guide 24 is provided with multiple light sources 23. By emitting light simultaneously on opposite sides of the pattern layer 22, the brightness and uniformity of the ambient light assembly 20 can be effectively improved, thereby enhancing the lighting effect.
[0074] In this application, the light-transmitting substrate 21 can be a flat plate, or a curved or arc-shaped surface. Both the first glass 211 and the second glass 212 can be made of inorganic glass or organic glass (resin). Inorganic glass includes, but is not limited to, soda-lime glass (also known as soda-lime silicate glass), aluminosilicate glass, borosilicate glass, lithium aluminum silicate glass, alkali-free glass, and quartz glass. From the perspective of improving strength, inorganic glass can also be tempered glass, which can be either chemically strengthened glass or physically strengthened glass. Organic glass (resin) includes, but is not limited to, polycarbonate resin, polystyrene resin, aromatic polyester resin, acrylic resin, polyester resin, polyarylate resin, condensation polymers of halogenated bisphenol A and ethylene glycol, urethane acrylate resin, and acrylic resin containing halogenated aryl groups.
[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
