Description

Technical Field

[0001] The present application relates to the technical field of vehicle decoration, and in particular to an ambient light assembly and a vehicle. Background Art

[0002] With the rapid development of the automotive industry, more and more cars are equipped with ambient lighting assemblies, which enhance the interior aesthetics by emitting ambient light patterns. Conventional ambient lighting assemblies consist of glass, a light guide, lamp beads, and an ambient light pattern. The ambient light pattern is positioned on the interior or exterior surface of the glass. Light emitted by the lamp beads is refracted onto the glass by the light guide and reflected back into the vehicle by the ambient light pattern, creating an ambient lighting effect. However, conventional ambient lighting assemblies suffer from issues such as over-brightness in some areas and uneven brightness, which compromises the lighting effect of the ambient lighting assembly. Summary of the Invention

[0003] Based on this, it is necessary to provide an atmosphere light assembly and a vehicle to address the problem that some areas of the atmosphere light assembly in the related art are locally too bright and the luminous brightness is uneven.

[0004] An ambient light assembly, comprising:

[0005] A light-transmitting substrate having a first surface and a second surface disposed opposite to each other;

[0006] a pattern layer, disposed on the light-transmitting substrate;

[0007] A luminous light source and a light guide are provided on the side of the first surface of the light-transmitting substrate, wherein light emitted by the luminous light source can be guided by the light guide to the light-transmitting substrate and reflected by the pattern layer toward the side of the first surface;

[0008] a first light-shielding layer, disposed on the first surface of the light-transmitting substrate, the first light-shielding layer being disposed around the light source, the light guide member, and a projection of the pattern layer on the first surface;

[0009] In which, in the projection on the first surface, the first shading layer includes an angle shading portion located between the pattern layer and the light guide, and the angle shading portion has an arc profile close to the pattern layer and a straight line profile close to the light guide, and the angle between the tangent of the arc profile close to the end point of the straight line profile and the straight line profile is less than or equal to 30°.

[0010] The aforementioned ambient light assembly ensures that, in the projection onto the first surface, the angle between the tangent of the arc profile near the endpoint of the linear profile and the linear profile is less than or equal to 30°. This can constrain the coverage area of ​​the first light-shielding layer between the light guide and the pattern layer, allowing the first light-shielding layer to effectively shield the corner region between the light guide and the pattern layer, preventing the occurrence of light or dark stripes, halos, and other phenomena in the corner region, thereby improving the uniformity and luminous effect of the ambient light assembly. Furthermore, the coverage area of ​​the first light-shielding layer between the light guide and the pattern layer is not excessively large, allowing light to be smoothly transmitted within the transparent substrate 21 from the hollow region formed by the first light-shielding layer between the light guide and the pattern layer to the region containing the pattern layer, thereby reducing the impact of the first light-shielding layer on the brightness of the ambient light assembly.

[0011] In one embodiment, in the projection on the first surface, a tangent line of the arc profile close to an end point 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 also includes a transition profile connecting the circular arc profile and the straight line profile, and the angle between the transition profile and the straight line profile, as well as the angle between the transition profile and the tangent of the circular arc profile close to the end point of the straight line profile, are greater than the angle between the tangent of the circular arc profile close to the end point of the straight line profile and the straight line profile.

[0013] In one embodiment, in the projection on the first surface, the first light-shielding layer includes two corner light-shielding portions, the two corner light-shielding portions are arranged at an interval, and transition profiles of the two corner light-shielding portions are opposite to each other.

[0014] In one embodiment, the transition profile is perpendicular to the straight profile; or

[0015] In a direction along the straight line profile pointing away from the other corner shading portion, the transition profile is inclined relative to the straight line profile toward a 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 shading portion away from the pattern layer, and the light source is located on the side of the light guide facing away from the corner light shading portion. The light emitted by the light source can be incident on the transparent substrate after being transmitted by the light guide, and then be transmitted within the transparent substrate along the direction of the light guide pointing to the pattern layer.

[0017] In one embodiment, the atmosphere light assembly further includes a light shield, which is disposed on the first surface of the light-transmitting substrate and covers the light source and the light guide. In the projection on the first surface, at least a portion of the arc contour close to 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 arc contour close to the straight contour and the edge contour 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 forming the first surface on the side facing away from the second glass, and the second glass forming the second surface on the side facing away from the first glass. The pattern layer is arranged between the first glass and the second glass, or on the first glass, or on the first surface. The atmosphere light assembly also includes a second shading layer, and in the projection on the first surface, the second shading layer is arranged around the pattern layer.

[0020] In one embodiment, the atmosphere light assembly further includes a transition shading structure, which is arranged on the same layer as the second shading layer. In the projection on the first surface, the transition shading structure is arranged between the pattern layer and the second shading layer, and the inner contour of the transition shading structure is adapted to the shape of the outer contour of the pattern layer.

[0021] In one embodiment, the atmosphere light assembly further includes an adhesion layer stacked between the first glass and the second glass, the second shading layer and the transition shading structure are arranged between the second glass and the adhesion layer, and the pattern layer is arranged between the first glass and the adhesion layer.

[0035] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0037] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0038] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, 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 embodiment.

[0041] The ambient light assembly in the related art includes components such as glass, light guides, lamp beads, ambient light patterns, and a light-shielding ink layer. The ambient light pattern is provided on the glass, and the light emitted by the lamp beads can be transmitted by the light guide and then projected onto the glass, and reflected by the ambient light pattern to form an ambient light effect. The light-shielding ink layer is provided on the glass and arranged around the ambient light pattern. The light in the area of ​​the glass covered by the light-shielding ink layer is blocked by the light-shielding ink layer and cannot be emitted, thereby preventing the area outside the ambient light pattern from emitting light. However, in the ambient light assembly in the related art, when the contour of the ambient light pattern close to the light guide is arc-shaped, the light-shielding ink layer usually does not cover the corner area between the arc-shaped contour of the ambient light pattern and the light guide, causing the corner area between the arc-shaped contour and the light guide to shine, or generating light and dark stripes, halos, and other phenomena, resulting in uneven lighting of the ambient light assembly and affecting the lighting effect.

[0042] To solve the above problems, the present application provides an ambient light assembly and a vehicle.

[0043] See Figure 1 and Figure 2 The ambient light assembly 20 provided in this application can be applied to a vehicle 10, which also includes a vehicle body 11, and the ambient light assembly 20 is installed on the vehicle body 11. The ambient light assembly 20 can be used to emit a specific light pattern toward the inside of the vehicle to form an ambient light effect, thereby enhancing the aesthetics of the interior of the vehicle. The vehicle 10 provided in this application includes but is not limited to any type of vehicle such as a sedan, a sports utility vehicle, a multi-purpose commercial vehicle, a sports car, and a van. The ambient light assembly 20 includes but is not limited to the side windows, sunroof, and rear windshield of the vehicle 10. Figure 1 The side windows are used as an example.

[0044] refer to Figure 3 and Figure 4As shown, in some embodiments, the ambient light assembly 20 includes a translucent substrate 21, a patterned layer 22, a light source 23, a light guide 24, and a first light-shielding layer 25. The translucent substrate 21 is made of, but not limited to, a translucent material such as glass. The translucent substrate 21 has a first surface 2111 and a second surface 2121 disposed opposite each other. When the ambient light assembly 20 is mounted on the vehicle body 11, the first surface 2111 can face the vehicle interior, while the second surface 2121 can face the vehicle exterior. The patterned layer 22 is disposed on the translucent substrate 21, and the light source 23 and light guide 24 are disposed on the side of the translucent substrate 21 where the first surface 2111 is located. The light source 23 is configured to emit light toward the light guide 24, which is configured to guide the light emitted by the light source 23 toward the translucent substrate 21 through refraction or other means. This light is then reflected by the patterned layer 22 within the translucent substrate 21 toward the first surface 2111, thereby reflecting it toward the vehicle interior, creating an ambient light effect.

[0045] The first light-shielding layer 25 is disposed on the first surface 2111 of the transparent substrate 21. The first light-shielding layer 25 is disposed around the light source 23, the light guide 24, and the projection of the pattern layer 22 on the first surface 2111. The material of the first light-shielding layer 25 includes, but is not limited to, a light-shielding material such as ink. The first light-shielding layer 25 can block light, preventing light from emitting from the transparent substrate 21 in the area where the first light-shielding layer 25 is located, thereby enhancing the patterned light effect emitted from the area where the pattern layer 22 is located.

[0046] Further, combined with 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 arc profile 253 close to the pattern layer 22. The corner light shielding portion 251 covers a corner region formed between the arc profile 253 of the pattern layer 22 and the light guide 24 where at least a portion of the pattern layer 22 is not provided. The corner light shielding portion 251 has a straight line profile 254 close to the light guide 24, i.e., away from the arc profile 253. The arc profile 253 is close to the end point of the straight line profile 254 ( Figure 5 The endpoint A shown and Figure 6 The angle between the tangent line of the end point B) and the straight line profile 254 is less than or equal to 30°. Figure 7 As shown, Figure 7 One of the corner shading parts 251 is shown. Figure 7 The angle H shown in FIG is the angle between the tangent line (straight line I) of the arc profile 253 of the corner light shielding portion 251 close to the end point of the straight profile 254 and the straight profile 254 (extension line).

[0047] It is understandable that the definition of the angle between the straight profile 254 and the tangent of the arc profile 253 close to the end point of the straight profile 254 can constrain the coverage of the angle 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 C is shown in FIG, the corner shading portion 251 of the first shading 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 profile 253 of the pattern layer 22 and the side surface of the light guide 24 facing the pattern layer 22 is less than or equal to 30°.

[0048] Combine Figure 2 As shown, in some embodiments, when projected onto the first surface 2111, two arcuate contours 253 transition between the pattern layer 22 and a light guide 24. These arcuate contours 253 may correspond to the two ends of the light guide 24, resulting in two corner regions between the light guide 24 and the pattern layer 22. The first light shielding layer 25 includes two corner shields 251, each with its arcuate contours 253 positioned close to the pattern layer. It is understood that if the coverage area of ​​the corner shields 251 in the corner regions is too small, for example, if the distance between the two corner shields 251 is too large, portions of the corner regions may not be blocked by the first light shielding layer 25, resulting in them emitting light. If the coverage area of ​​the corner shields 251 in the corner regions is too large, for example, if the distance between the two corner shields 251 is too small, the corner shields 251 may absorb light that is transmitted from the light guide 24 region to the pattern layer 22 region on the transparent substrate 21, affecting the 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 shield 251. Light emitted by the light source 23 is guided by the light guide 24 and then incident on the transparent substrate 21 from the first surface 2111. The light is then guided within the transparent substrate 21 in the direction from the light guide 24 toward the pattern layer 22, thereby conducting light from the location of the light guide 24 to the location of the pattern layer 22, forming an ambient light pattern. In this manner, the light guide 24's light homogenization and the light's conduction and dispersion within the transparent substrate 21 facilitate improving the uniformity of the ambient light pattern emitted by the ambient light assembly 20, enhancing the ambient light effect.

[0050] Therefore, the above-mentioned atmosphere lamp assembly 20 provided in some embodiments of the present application enables, in the projection on the first surface 2111, the angle between the tangent of the arc profile 253 close to the end point of the straight profile 254 and the straight profile 254 is less than or equal to 30°, which 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 profile 253 and the light guide 24, so that the first light-shielding layer 25 can effectively block the corner area between the light guide 24 and the pattern layer 22, shielding the corner area from brightness or the appearance of light and dark stripes, halos, etc., which is beneficial to improving the luminous uniformity and luminous effect of the atmosphere lamp 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 in the transparent base 21 to the area where the pattern layer 22 is located, thereby reducing the influence of the first light-shielding layer 25 on the brightness of the ambient light assembly 20.

[0051] In some embodiments, in the projection onto the first surface 2111, the tangent of the arc profile 253 near the endpoint of the linear profile 254 is parallel to the linear profile 254, that is, parallel to the side of the light guide 24 facing the pattern layer 22. It can be understood that, based on the position where the tangent of the arc profile 253 near the endpoint of the linear profile 254 is parallel to the side of the light guide 24 facing the pattern layer 22, the inward corner area is very small, and the need for light to propagate from the light guide 24 to the pattern layer 22 is greater, while the area of ​​the outward corner area increases rapidly. Therefore, by arranging the tangent of the arc profile 253 at the endpoint parallel to the linear profile 254 and the side of the light guide 24 facing the pattern layer 22, the corner light shield 251 can effectively block the light from the corner area between the light guide 24 and the pattern layer 22 while not easily affecting the light propagation between the light guide 24 and the pattern layer 22, effectively improving the lighting effect of the ambient light assembly 20.

[0052] In some embodiments, in the projection on the first surface 2111, the corner shading portion 251 also includes a transition profile 255 connected to the arc profile 253 and the straight line profile 254. The transition profile 255 can be a straight line. The angle between the transition profile 255 and the straight line profile 254, and the angle between the transition profile 255 and the tangent of the arc profile 253 close to the end point of the straight line profile 254 are both greater than the angle between the tangent of the arc profile 253 close to the end point of the straight line profile 254 and the straight line profile 254.

[0053] It can be understood that, compared to related art, the ambient light assembly 20 provided in this application increases the coverage area of ​​the first light-shielding layer 25 in the corner region, thereby increasing the length of the straight profile 254. Furthermore, if the circular profile 253 were directly connected to the straight profile 254, the curvature of the circular profile 253 near the straight profile 254 would likely change abruptly, affecting the contour harmony of the pattern layer 22 and, consequently, the appearance of the ambient light assembly 20. Therefore, by adding a transition profile 255 between the circular profile 253 and the straight profile 254, the angular transitions between the transition profile 255 and the circular profile 253, and between the transition profile 255 and the straight profile 254, prevent the abrupt curvature changes of the circular profile 253, resulting in a more harmonious overall contour line of the pattern layer 22 and improving the appearance of the ambient light assembly 20.

[0054] When the first shading layer 25 includes two corner shading portions 251, the two corner shading portions 251 are arranged at intervals, and the transition profiles 255 of the two corner shading portions 251 are opposite, the area where the projection of the pattern layer 22 on the first surface 2111 is located can present a square area with four rounded corners.

[0055] refer to Figure 5 and Figure 6 As shown, in some embodiments, the transition profile 255 is perpendicular to the straight profile 254. Thus, by adjusting the length of the transition profile 255, the curvature differences at various locations of the arc profile 253 can be minimized, thereby improving the overall appearance of the ambient light assembly 20. In other embodiments, the transition profile 255 can be tilted relative to the straight profile 254. Furthermore, along a direction away from the other corner light shielding portion 251 along one of the straight profiles 254, the transition profile 255 can be tilted relative to the straight profile 254 toward the side of the arc profile 253. This can create a smoother angular transition between the arc profile 253, the transition profile 255, and the straight profile 254, thereby improving the overall appearance of the ambient light assembly 20.

[0056] In some embodiments, in the projection onto 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 profiles 255 of the two corner light shielding portions 251 face each other, and the portion of the first light shielding layer 25 between the two transition profiles 255 is hollowed out. The light guide 24 can reflect light emitted by the luminous light source 23 toward the side of the first surface 2111. The light enters the transparent substrate 21 from the first surface 2111 at the light guide 24 and is reflected within the transparent substrate 21 to the pattern layer 22. The provision of the light guide 24 can homogenize the light emitted by the luminous light source 23, improving the uniformity of the light entering the transparent substrate 21, thereby enhancing the ambient lighting effect.

[0057] The specific configuration of the light guide 24 is not limited, as long as it can evenly distribute the light emitted by the light source 23 and transmit it to the transparent substrate 21. In the drawings of this application, a light guide column is used as an example of the light guide 24. Materials for the light guide 24 include, but are not limited to, polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene (PS), and the like. In other embodiments, the light guide 24 can also be a grating structure layer disposed on the first surface 2111, which transmits the light emitted by the light source 23 to the transparent substrate 21 through diffraction and 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 transparent substrate 21 and covers the light source 23 and the light guide 24. For example, the light shield 26 is disposed on the first surface 2111 and encloses the transparent substrate 21 to form a receiving space. The light source 23 and the light guide 24 are disposed within the receiving space and fixed to the first surface 2111 of the transparent substrate 21. The light shield 26 provides a sealed protection for the light source 23 and the light guide 24 and shields their appearance.

[0059] Further, refer to Figure 4 As shown, in some embodiments, in the projection on the first surface 2111, at least the portion of the arc profile 253 near the light guide 24 is covered by the light shield 26. In this way, the light shield 26 can shield the transition between the arc profile 253, the transition profile 255, and the straight profile 254, thereby shielding the corners of the contour lines so that the corners are not exposed, which helps to improve the appearance coordination of the ambient light assembly 20.

[0060] In some embodiments, in the projection on the first surface 2111, the arc profile 253 is close to the shortest distance between the end point of the straight profile 254 and the edge profile of the light shield 26 (for example, Figure 4 The distance D) shown is greater than or equal to 2.5 mm, for example, the distance D may be exactly equal to 2.5 mm, so that the corners of the contour line can be effectively shielded by the light shield 26 , thereby 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 is formed with 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 provision of the mounting groove 252 reserves installation space for the light guide 24 and the light source 23, preventing the first light-shielding layer 25 from blocking light from the light guide 24 from being emitted toward the transparent substrate 21. Aside from 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, effectively shielding light from emitting from areas outside the pattern layer 22, thereby enhancing the lighting effect and harmonious appearance of the ambient light assembly 20.

[0062] In some embodiments, the transparent 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 transparent substrate 21 .

[0063] refer to Figure 3 and Figure 4 As shown, in some embodiments, the light-transmitting substrate 21 may also be multi-layer glass. Figure 3 and Figure 4 In this example, the transparent substrate 21 is a double-layer glass. The transparent substrate 21 includes a first glass 211 and a second glass 212, which are 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. The pattern layer 22 is disposed between the first and second glass 211, 212. The pattern layer 22 can be disposed on one of the opposing surfaces of the first and second glass 211, 212. The first and second glass 211, 212 can also be bonded together via an 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 and second glass 211, 212. This configuration allows the double-layer glass structure of the transparent substrate 21 to protect the pattern layer 22, making the placement of the pattern layer 22 more stable and reliable.

[0064] It is understood that the light guide 24 has a light incident surface 241 opposite the light 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. Light emitted by the light source 23 can enter the light guide 24 from the light incident surface 241. After being refracted by the light guide 24, the light can be emitted from the third surface 243 into the first glass 211 and directly hit the pattern layer 22, or be transmitted to the pattern layer 22 after multiple reflections within the first glass 211. The light can also be emitted from the third surface 243 of the light guide 24 into the first glass 211 and directly hit the pattern layer 22, or be transmitted 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 atmosphere lamp assembly 20 further includes a second light-shielding layer 27 that is arranged on the same layer as the pattern layer 22 and is arranged around the pattern layer 22. The second light-shielding layer 27 can shield components such as the light source 23 and the light guide 24, so that components such as the light source 23 and the light guide 24 will not be exposed on the second surface 2121 side of the light-transmitting substrate 21. At the same time, it is beneficial to prevent light from being emitted from the area outside the pattern layer 22 corresponding to the second glass 212, which is beneficial to improving the appearance integrity and lighting effect of the atmosphere lamp assembly 20.

[0066] In some embodiments, the ambient light assembly 20 further includes a transitional light-shielding structure 28 disposed on the same layer as the pattern layer 22 and the second light-shielding layer 27, and disposed between the pattern layer 22 and the second light-shielding layer 27. The transitional light-shielding structure 28 may be a dotted ink structure with an irregular texture. The transitional light-shielding structure 28 scatters and refracts light, causing it to propagate in different directions, thereby dispersing concentrated light. This helps to make the ambient light pattern's light more uniform and softer, avoids noticeable differences in brightness, and enhances the visual experience. It also enhances the luminous effect and the layered and three-dimensional appearance of the exterior. It also helps to conceal structural flaws or splicing marks, such as outlines, to enhance the overall appearance.

[0067] In some embodiments, as projected onto the first surface 2111, the inner contour of the transitional light-shielding structure 28 conforms to the outer contour of the patterned 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 conform to the outer contour of the transitional 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 transitional light-shielding structure 28 is not excessive. It can be appreciated that the provision of the transition contour 255 extends the length of the straight contour 254 to allow the corner light-shielding portion 251 to effectively shield the corner region between the light guide 24 and the patterned layer 22 without causing a sudden change in the curvature of the arc contour 253. This allows the arc contour 253 to conform to or approximate the curvature of all portions of the inner contour of the transitional light-shielding structure 28, effectively enhancing the appearance and 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 is connected to the inner contour of the transitional 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 transitional light-shielding structure 28. The outer outline of the transitional light-shielding structure 28 is connected to the inner outline of the second light-shielding layer 27. 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 arc 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 contours of the patterned layer 22, the transitional light-shielding structure 28, and the second light-shielding layer 27 all roughly match in curvature, allowing the transitional light-shielding structure 28 and the second light-shielding layer 27 to cooperate effectively shielding the area outside the patterned layer 22, while also enhancing the overall appearance of the ambient light assembly 20. The arc contour 253 can align with the inner contour of the second light-shielding layer 27, while the curvature 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 provision of the straight contour 254, the curvature of the arc contour 253 near the straight contour 254 does not differ significantly from the curvature of the second light-shielding layer 27 and the transitional light-shielding structure 28, thereby enhancing the overall appearance of the ambient light assembly 20.

[0069] Of course, the arrangement of the second shading layer 27, the transition shading 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 shading layer 27 and the transition shading structure 28 can be provided on any side of the opposite sides of the adhesive layer 213, and the pattern layer 22 can be provided on any side of the opposite sides of the adhesive layer 213 between the first glass 211 and the second glass 212, or the pattern layer 22 can also be provided in the first glass 211, for example, formed by a shape pattern provided in the first glass 211.

[0070] Furthermore, in some embodiments, the second light-shielding layer 27 and the transitional 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, thereby enhancing the ambient light effect. Furthermore, the distribution of the various structural layers is more rational, which facilitates optimizing the structural layout and manufacturing process of the ambient light assembly 20. This prevents the formation processes of the various structural layers from interfering with each other, thereby reducing the manufacturing difficulty of the ambient light assembly 20 and improving the structural reliability of the ambient light assembly 20.

[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 further has a contour line located on the side of the light guide 24 facing away from the straight contour 254, for example Figure 8 As shown in the outline E, 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 within the light guide 24 from being emitted toward the transparent substrate 21, thereby improving the light utilization efficiency of the ambient light assembly 20.

[0072] It should be noted that in the present application, the first shading layer 25, the second shading layer 27 and the transition shading structure 28 can all be shading materials such as ink layers provided on the light-transmitting substrate 21, and the pattern layer 22 can be an ink material provided on the light-transmitting substrate 21 and having a specific distribution pattern. The specific distribution pattern of the pattern layer 22 can be designed according to the luminous effect of the atmosphere lamp, which is not limited in the present application.

[0073] The light source 23 includes but is not limited to LED lamp beads, and the light guide 24 includes but is not limited to any suitable light guide material such as acrylic, polycarbonate, etc. The light guide 24 can be in a strip shape, and there can be multiple light sources 23. The multiple light sources 23 can be arranged in sequence along the length direction of the light guide 24 to achieve a uniform and high-brightness lighting effect. Figure 2 and Figure 8 As shown, in some embodiments, the atmosphere light assembly 20 may be provided with two groups of light guides 24 and light sources 23. The two groups of light guides 24 are respectively arranged on two opposite sides of the pattern layer 22. Each light guide 24 is correspondingly provided with multiple light sources 23. By emitting light at the same time on two opposite sides of the pattern layer 22, the luminous brightness and luminous uniformity of the atmosphere light assembly 20 can be effectively improved, thereby improving the luminous effect.

[0074] In the present application, the light-transmitting substrate 21 may be in the form of a flat plate, or in the form of a curved or cambered surface. Both the first glass 211 and the second glass 212 may 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, borate glass, borosilicate glass, lithium aluminum silicate glass, alkali-free glass, quartz glass, and the like. From the perspective of increasing strength, inorganic glass may also be tempered glass, and tempered glass may be any of chemically tempered glass and physically tempered glass. Organic glass (resin) includes, but is not limited to, polycarbonate resin, polystyrene resin, aromatic polyester resin, acrylic resin, polyester resin, polyarylate resin, condensation product of halogenated bisphenol A and ethylene glycol, acrylic urethane resin, acrylic resin containing halogenated aromatic groups, and the like.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
