Obviously, the embodiments described in this application are only a portion of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort are within the protection scope of this application.

Those skilled in the art will explicitly and implicitly understand that the implementations described in this application can be combined with other implementations.

[0019] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device that includes one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0020] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic cross-sectional view of the functional glass 100 provided in this application embodiment. Figure 2 This is a schematic cross-sectional view of another functional glass 100 provided in an embodiment of this application. The functional glass 100 includes a first glass plate 10 and a photoluminescent functional layer 20.

[0021] When categorized by the mechanical properties of the glass, the first glass plate 10 can be a regular glass plate or a tempered glass plate, etc.; when categorized by the optical properties of the glass, the first glass plate 10 can be a clear glass plate, a gray glass plate, or a green glass plate, etc. In one possible embodiment, the light transmittance of the first glass plate 10 can be greater than or equal to 92%.

[0022] The thickness of the first glass plate 10 can range from 2.1 mm to 6 mm. For example, the thickness of the first glass plate 10 can be 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm, 3 mm, 3.2 mm, 3.3 mm, 3.5 mm, 3.7 mm, 3.9 mm, 4 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 4.9 mm, 5 mm, 5.2 mm, 5.3 mm, 5.5 mm, 5.7 mm, 5.9 mm, or 6 mm.

[0023] A photoluminescent functional layer 20 is disposed on the surface of the first glass plate 10. Optionally, the photoluminescent functional layer 20 is directly formed on the surface of the first glass plate 10, or the photoluminescent functional layer 20 is formed on another glass plate and connected to the first glass plate 10. In the embodiment where the photoluminescent functional layer 20 is directly formed on the surface of the first glass plate 10, the process for forming the photoluminescent functional layer 20 on the surface of the first glass plate 10 includes, but is not limited to, one or more of printing, spraying, and deposition. In the embodiment where the photoluminescent functional layer 20 is formed on another glass plate and connected to the first glass plate 10, the photoluminescent functional layer 20 and the first glass plate 10 can be connected by an adhesive layer, which includes, but is not limited to, a polyvinyl butyral (PVB) layer or an ethylene-vinyl acetate copolymer (EVA) layer.

[0024] The photoluminescent functional layer 20 can be a whole layer structure laid flat on the surface of the first glass plate 10, or it can be patterned.

[0025] The photoluminescent functional layer 20 emits light of at least two colors when excited by a target light source, and changes color when excited by sunlight. Understandably, the photoluminescent functional layer 20 possesses both photoluminescence and photochromic effects. Thus, the functional glass 100 can provide ambient lighting effects both during the day and at night.

[0026] The photoluminescent functional layer 20 comprises photoluminescent materials and photochromic materials. Photoluminescent materials may include one or more of inorganic phosphors, organometallic complexes, semiconductor quantum dots, and rare-earth luminescent materials. Photochromic materials may be organic photochromic dyes, such as diarylethylene derivatives, Schiff bases, spiropyran derivatives, and ursolic anhydrides; or inorganic photochromic materials, such as tungsten trioxide, molybdenum trioxide, and titanium dioxide; or polymeric photochromic materials, such as azobenzene derivatives, triphenylmethane derivatives, and polyoxymethylene derivatives. The photoluminescent and photochromic materials may be located in the same layer to form a monolayer photoluminescent functional layer 20; or they may be located in different layers to form a layered photoluminescent functional layer 20.

[0027] The photoluminescent functional layer 20 emits visible light when excited by the target light source. The photoluminescent functional layer 20 may include a first photoluminescent material and a second photoluminescent material. The first photoluminescent material emits monochromatic visible light when excited by the target light source, and the second photoluminescent material emits another monochromatic visible light when excited by the target light source.

[0028] In one possible embodiment, the photoluminescent layer 20 emits at least two of red, green, and blue light when excited by a target light source. Optionally, the photoluminescent layer 20 emits red and green light when excited by a target light source; or, it emits red and blue light; or, it emits green and blue light; or, it emits red, green, and blue light. Of course, in other possible embodiments, the photoluminescent layer 20 may also emit other colors of visible light when excited by a target light source, including but not limited to orange, cyan, or purple.

[0029] In the embodiment where the photoluminescent material is a quantum dot, the size and shape of the quantum dot determine the color of the emitted light. Therefore, the first and second photoluminescent materials can be quantum dots with different sizes and / or shapes.

[0030] By enabling the photoluminescent functional layer 20 to emit light of at least two colors when excited by the target light source, it is beneficial to combine and form a variety of colored lights to achieve a colorful ambient lighting effect.

[0031] The target light source can be a monochromatic visible light source, a multicolor mixed visible light source, an ultraviolet light source, or an infrared light source, etc.

[0032] The functional glass 100 provided in this application includes a first glass plate 10 and a photoluminescent functional layer 20. The photoluminescent functional layer 20 is disposed on the surface of the first glass plate 10. The photoluminescent functional layer 20 emits light when excited by a target light source and changes color when excited by sunlight. Thus, in the case of weak ambient light (e.g., at night or on a cloudy day), the functional glass 100 can achieve an ambient lighting effect by emitting light through the photoluminescent functional layer 20 when excited by the target light source. In the case of strong ambient light (e.g., on a sunny day), although the luminescence effect of the photoluminescent functional layer 20 is weakened by the ambient light, the photoluminescent functional layer 20 changes color when excited by sunlight, thus creating a complementary effect of luminescence and color change. This reduces the impact of ambient light on the ambient lighting effect of the functional glass 100 and improves the user experience. In addition, the photoluminescent functional layer 20 emits at least two colors of light when excited by the target light source, which is beneficial for combining and forming multiple colors of light to achieve a colorful ambient lighting effect.

[0033] In one possible implementation, such as Figure 1As shown, the photoluminescent functional layer 20 includes a first sub-photoluminescent functional layer 201, an intermediate dielectric layer 202, and a second sub-photoluminescent functional layer 203 stacked sequentially. The first sub-photoluminescent functional layer 201 emits light when excited by the target light source, and the second sub-photoluminescent functional layer 203 changes color when excited by sunlight.

[0034] Understandably, in this embodiment, the photoluminescent functional layer 20 is a layered structure formed by photoluminescent material and photochromic material. The first sub-photoluminescent functional layer 201 includes a photoluminescent material, and the second sub-photoluminescent functional layer 203 includes a photochromic material. Optionally, the first glass plate 10, the first sub-photoluminescent functional layer 201, the intermediate dielectric layer 202, and the second sub-photoluminescent functional layer 203 are stacked sequentially; alternatively, the first glass plate 10, the second sub-photoluminescent functional layer 203, the intermediate dielectric layer 202, and the first sub-photoluminescent functional layer 201 are stacked sequentially.

[0035] The thicknesses of the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203 may be the same or different. In one possible embodiment, the thickness of the first sub-photoluminescent functional layer 201 may range from 10 μm to 50 μm, and the thickness of the second sub-photoluminescent functional layer 203 may also range from 10 μm to 50 μm. For example, the thickness of the first sub-photoluminescent functional layer 201 may be 10 μm, 15 μm, 20 μm, 23 μm, 30 μm, 37 μm, 44 μm, or 50 μm. The thickness of the second sub-photoluminescent functional layer 203 may be 10 μm, 13 μm, 20 μm, 25 μm, 30 μm, 36 μm, 47 μm, or 50 μm.

[0036] By setting the thickness of the first sub-photoluminescent functional layer 201 to 10 μm to 50 μm and the thickness of the second sub-photoluminescent functional layer 203 to 10 μm to 50 μm, the manufacturing cost of the functional glass 100 is reduced while ensuring the light-emitting effect of the first sub-photoluminescent functional layer 201 and the color-changing effect of the second sub-photoluminescent functional layer 203. Of course, in other possible embodiments, the thickness of the first sub-photoluminescent functional layer 201 can be greater than 50 μm, and the thickness of the second sub-photoluminescent functional layer 203 can be greater than 50 μm.

[0037] The intermediate dielectric layer 202 serves to physically connect the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203, and to chemically block the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203. The intermediate dielectric layer 202 physically connects the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203, allowing the first glass plate 10 and the photoluminescent functional layer 20 to form an integral structure. The intermediate dielectric layer 202 chemically blocks the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203, preventing chemical reactions from occurring on their surfaces due to contact, thus avoiding any impact on their mechanical or optical properties.

[0038] Optionally, the intermediate dielectric layer 202 can be a PVB layer or an EVA layer. The thickness of the intermediate dielectric layer 202 can be less than or equal to the thickness of the first glass plate 10. The thickness of the intermediate dielectric layer 202 can be greater than the thickness of the first sub-photoluminescent functional layer 201 and greater than the thickness of the second sub-photoluminescent functional layer 203. In one possible embodiment, the thickness of the intermediate dielectric layer 202 can range from 0.38 mm to 1.52 mm, for example: 0.38 mm, or 0.76 mm, or 1.14 mm, or 1.52 mm, etc.

[0039] This embodiment improves the mechanical and optical properties of the photoluminescent functional layer 20 by making the photoluminescent functional layer 20 include a first sub-photoluminescent functional layer 201, an intermediate dielectric layer 202, and a second sub-photoluminescent functional layer 203 stacked sequentially, with the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203 separated by the intermediate dielectric layer 202. Furthermore, it offers a wider selection of photoluminescent materials for the first sub-photoluminescent functional layer 201 and photochromic materials for the second sub-photoluminescent functional layer 203, which is beneficial for the production and manufacturing of the functional glass 100 and can reduce costs.

[0040] In one possible embodiment, the first sub-photoluminescent functional layer 201 includes a first transparent substrate and photoluminescent particles dispersed in the first transparent substrate, and the second sub-photoluminescent functional layer 203 includes a second transparent substrate and photochromic molecules dissolved in the second transparent substrate.

[0041] Understandably, photoluminescent materials exist entirely or primarily in particulate form in the first transparent substrate. Photochromic materials exist entirely or primarily in molecular form in the second transparent substrate.

[0042] The first transparent substrate is primarily made of transparent resin. The photoluminescent material can be uniformly dispersed within the first transparent substrate, or it can be non-uniformly dispersed within it. In one possible embodiment, the photoluminescent material of the first sub-photoluminescent functional layer 201 can be quantum dots. In this embodiment, the photoluminescent material is nanoscale in size, primarily inorganic, and is physically mixed with the transparent resin without chemical reaction. This allows the first sub-photoluminescent functional layer 201 to include the first transparent substrate and photoluminescent particles dispersed within it. The first sub-photoluminescent functional layer 201 can be obtained by mixing transparent resin, solvent, and photoluminescent material, followed by curing.

[0043] The second transparent substrate is primarily made of transparent resin. In one possible embodiment, the photochromic material of the second sub-photochromic functional layer 203 can be an organic photochromic dye. In this embodiment, the photochromic material is readily soluble in the transparent resin; that is, the photochromic material and the transparent resin are not only physically mixed but also undergo a chemical reaction, thereby enabling the second sub-photochromic functional layer 203 to include the second transparent substrate and photochromic molecules dissolved in the second transparent substrate. The second sub-photochromic functional layer 203 can be obtained by mixing transparent resin, solvent, and organic photochromic dye, followed by curing. Of course, in other possible embodiments, the material of the second sub-photochromic functional layer 203 may also include an ultraviolet absorbing material to improve the photo-oxidation resistance of the second sub-photochromic functional layer 203.

[0044] In this embodiment, the first sub-photoluminescent functional layer 201 has a good light emission effect when excited by the target light source, and the second sub-photoluminescent functional layer 203 has a good color-changing effect when excited by sunlight.

[0045] In another possible implementation, such as Figure 2 As shown, the photoluminescent functional layer 20 includes a third transparent substrate, photoluminescent molecules dissolved in the third transparent substrate, and photochromic molecules dissolved in the third transparent substrate.

[0046] Understandably, photoluminescent materials exist entirely or primarily in molecular form within the third transparent substrate. Similarly, photochromic materials exist entirely or primarily in molecular form within the third transparent substrate.

[0047] The third transparent substrate is primarily made of transparent resin. In one possible embodiment, the photoluminescent material of the photoluminescent functional layer 20 can be a metal-organic complex, and the photochromic material of the photoluminescent functional layer 20 can be an organic photochromic dye. In this embodiment, both the photoluminescent material and the photochromic material are readily soluble in the transparent resin; that is, the photoluminescent material, the photochromic material, and the transparent resin are not only physically mixed but also undergo a chemical reaction, thereby realizing that the photoluminescent functional layer 20 includes the third transparent substrate, photoluminescent molecules dissolved in the third transparent substrate, and photochromic molecules dissolved in the third transparent substrate.

[0048] In this embodiment, the photoluminescent material and photochromic material of the photoluminescent functional layer 20 are concentrated on one layer, which is beneficial to reducing the thickness of the functional glass 100.

[0049] In one possible implementation, the photoluminescent functional layer 20 has a light transmittance greater than or equal to 90% and a haze less than or equal to 2% when it is not emitting light and is not changing color.

[0050] The transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color is greater than or equal to 90%. This can be either the visible light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color is greater than or equal to 90%; or the sunlight transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color is greater than or equal to 90%. Haze refers to the cloud-like state caused by light scattering inside or on the surface of the photoluminescent functional layer 20, that is, the ratio of scattered transmitted light to total transmitted light, which is determined by the scattered light flux.

[0051] Optionally, the light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color is greater than or equal to 90% and less than or equal to 95%; or, the light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color can be greater than 95%. For example, the light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color can be 90%, 91%, 92%, 93%, 94%, 95%, 96%, or 97%. In this embodiment, the light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color is less than the light transmittance of the first glass plate 10. Of course, in other possible embodiments, the light transmittance of the photoluminescent functional layer 20 when it is not emitting light and not changing color can be greater than or equal to the light transmittance of the first glass plate 10.

[0052] Optionally, the haze of the photoluminescent functional layer 20 when it is not emitting light and not changing color is less than or equal to 2% and greater than or equal to 1%; or, the haze of the photoluminescent functional layer 20 when it is not emitting light and not changing color is less than 1%. For example, the haze of the photoluminescent functional layer 20 when it is not emitting light and not changing color can be 2%, or 1.9%, or 1.8%, or 1.7%, or 1.6%, or 1.5%, or 1.4%, or 1.3%, or 1.2%, or 1.1%, or 1%, or 0.9%, or 0.8%, or 0.7%.

[0053] In an embodiment where the photoluminescent functional layer 20 includes a first sub-photoluminescent functional layer 201, an intermediate dielectric layer 202, and a second sub-photoluminescent functional layer 203 stacked sequentially, the light transmittance of the first sub-photoluminescent functional layer 201 when not emitting light and not changing color can be greater than or equal to 90%, and the haze of the first sub-photoluminescent functional layer 201 when not emitting light and not changing color can be less than or equal to 2%. The light transmittance of the second sub-photoluminescent functional layer 203 when not emitting light and not changing color can be greater than or equal to 90%, and the haze of the second sub-photoluminescent functional layer 203 when not emitting light and not changing color can be less than or equal to 2%.

[0054] By making the light transmittance of the photosensitive functional layer 20 greater than or equal to 90% and the haze of the photosensitive functional layer 20 less than or equal to 2%, the photosensitive functional layer 20 can be made invisible, preventing users from seeing the photosensitive functional layer 20 from the outside of the functional glass 100.

[0055] In one possible implementation, such as Figure 3 As shown, Figure 3 for Figure 1 The functional glass 100 shown also includes a cross-sectional view of a second glass plate 30. The functional glass 100 further includes a second glass plate 30, and the first glass plate 10, the photoluminescent functional layer 20, and the second glass plate 30 are stacked sequentially.

[0056] When categorized by the mechanical properties of the glass, the second glass plate 30 can be a regular glass plate or a tempered glass plate, etc.; when categorized by the optical properties of the glass, the second glass plate 30 can be a clear glass plate, a gray glass plate, or a green glass plate, etc. In one possible embodiment, the light transmittance of the second glass plate 30 can be greater than or equal to 92%. The light transmittance of the second glass plate 30 can be the same as or different from that of the first glass plate 10.

[0057] The thickness of the second glass plate 30 can range from 2.1 mm to 6 mm. For example, the thickness of the first glass plate 10 can be 2.1 mm, 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm, 3 mm, 3.2 mm, 3.3 mm, 3.5 mm, 3.7 mm, 3.9 mm, 4 mm, 4.1 mm, 4.3 mm, 4.5 mm, 4.7 mm, 4.9 mm, 5 mm, 5.2 mm, 5.3 mm, 5.5 mm, 5.7 mm, 5.9 mm, or 6 mm. The thickness of the second glass plate 30 can be the same as or different from the thickness of the first glass plate 10.

[0058] In an embodiment where the photoluminescent functional layer 20 includes a first sub-photoluminescent functional layer 201 and a second sub-photoluminescent functional layer 203, the first sub-photoluminescent functional layer 201 can be directly formed on the surface of the first glass plate 10, and the second sub-photoluminescent functional layer 203 can be directly formed on the surface of the second glass plate 30. The first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203 are then connected through an intermediate dielectric layer 202 to form a functional glass 100 in which the first glass plate 10, the photoluminescent functional layer 20, and the second glass plate 30 are stacked sequentially. Alternatively, the first sub-photoluminescent functional layer 201 can be directly formed on the surface of the second glass plate 30, and the second sub-photoluminescent functional layer 203 can be directly formed on the surface of the first glass plate 10. The first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203 are then connected through an intermediate dielectric layer 202 to form a functional glass 100 in which the first glass plate 10, the photoluminescent functional layer 20, and the second glass plate 30 are stacked sequentially.

[0059] In embodiments where the photoluminescent functional layer 20 is a single-layer structure, the photoluminescent functional layer 20 can be directly formed on the surface of the first glass plate 10 and then connected to the second glass plate 30 through an adhesive layer; or, the photoluminescent functional layer 20 can be directly formed on the surface of the second glass plate 30 and then connected to the first glass plate 10 through an adhesive layer.

[0060] In this embodiment, the functional glass 100 is laminated glass, and the photoluminescent functional layer 20 has a good invisibility effect. When viewed from the side of the first glass plate 10 away from the second glass plate 30, or from the side of the second glass plate 30 away from the first glass plate 10, the photoluminescent functional layer 20 is difficult to see, which can improve the appearance and visual effect of the functional glass 100.

[0061] In one possible implementation, such as Figure 4 As shown, Figure 4 for Figure 3The functional glass 100 shown also includes a cross-sectional view of a light-adjusting layer 40. The functional glass 100 further includes a light-adjusting layer 40, which is disposed between the first glass plate 10 and the second glass plate 30, and is used to adjust the light transmittance of the functional glass 100.

[0062] The dimming layer 40 can be a polymer-dispersed liquid crystal (PDLC) film, an electrochromic (EC) film, or a suspended particle (SPD) film. The thickness of the dimming layer 40 can be less than the thickness of the first glass plate 10 and less than the thickness of the second glass plate 30. The dimming layer 40 can achieve dimming through methods including, but not limited to, electronic control, light control, temperature control, or voltage control.

[0063] In one possible embodiment, the dimming layer 40 may be located between the first sub-photoluminescent functional layer 201 and the second sub-photoluminescent functional layer 203. In this embodiment, the first glass plate 10, the first sub-photoluminescent functional layer 201, the dimming layer 40, the second sub-photoluminescent functional layer 203, and the second glass plate 30 are stacked sequentially, or the first glass plate 10, the second sub-photoluminescent functional layer 203, the dimming layer 40, the first sub-photoluminescent functional layer 201, and the second glass plate 30 are stacked sequentially. The first sub-photoluminescent functional layer 201 and the dimming layer 40, and the second sub-photoluminescent functional layer 203 and the dimming layer 40, can be physically connected and chemically barrierd by an adhesive layer, which can be a PVB layer or an EVA layer.

[0064] In another possible embodiment, the dimming layer 40 may be disposed between the first glass plate 10 and the photoluminescent functional layer 20. In this embodiment, the first glass plate 10, the dimming layer 40, the photoluminescent functional layer 20, and the second glass plate 30 are stacked sequentially. The dimming layer 40 and the first glass plate 10, and the dimming layer 40 and the photoluminescent functional layer 20, can be physically connected and chemically isolated by an adhesive layer, which can be a PVB layer or an EVA layer.

[0065] In a third possible embodiment, the dimming layer 40 can be disposed on the side of the photoluminescent functional layer 20 facing away from the first glass plate 10, that is, the dimming layer 40 is disposed between the photoluminescent functional layer 20 and the second glass plate 30. In this embodiment, the first glass plate 10, the photoluminescent functional layer 20, the dimming layer 40, and the second glass plate 30 are stacked sequentially, and the photoluminescent functional layer 20 and the dimming layer 40, as well as the dimming layer 40 and the second glass plate 30, can be physically connected and chemically isolated through a dielectric layer.

[0066] By including a dimming layer 40 between the first glass plate 10 and the second glass plate 30, the functional glass 100 can be formed to integrate light emission, color change and dimming. While realizing the dimming of the functional glass 100, the combination of the dimming layer 40 and the photoluminescent functional layer 20 can form more diverse ambient lighting effects.

[0067] like Figure 5 As shown, Figure 5 This is a schematic diagram of a functional glass assembly 200 provided in an embodiment of this application. The functional glass assembly 200 includes a target light source 21 and the functional glass 100 described in any of the above embodiments. The target light source 21 is disposed on one side of the functional glass 100 and is used to emit light toward the photoluminescent functional layer 20.

[0068] The target light source 21 can be an LED light strip. Optionally, the target light source 21 can be spaced apart on the side of the first glass plate 10; or, the target light source 21 can be spaced apart on the side of the photoluminescent functional layer 20; or, the target light source 21 can be spaced apart on the side of the second glass plate 30. This application does not specify the specific distance between the target light source 21 and the functional glass 100, as long as it can achieve the excitation effect on the photoluminescent functional layer 20.

[0069] In one possible implementation, the target light source 21 emits at least one of red light, green light, and blue light.

[0070] Optionally, the target light source 21 emits red light; or, the target light source 21 emits green light; or, the target light source 21 emits blue light. In one possible embodiment, the target light source 21 can emit blue light, and the photoluminescent functional layer 20 can emit red and green light when excited by the target light source 21. In this embodiment, the combination of the light emitted by the target light source 21 and the light emitted by the photoluminescent functional layer 20 when excited by the target light source 21 can form any color, enhancing the decorative and atmospheric qualities of the functional glass 100.

[0071] In one possible embodiment, the target light source 21 emits blue light, including but not limited to one or more combinations of wavelengths of 395 nm, 405 nm, 410 nm, 450 nm, and 460 nm. In this embodiment, the light emitted by the photoluminescent layer 20 under the excitation of the target light source can be a combination of red and green light. Thus, the combination of the light emitted by the photoluminescent layer 20 under the excitation of the target light source and the light emitted by the target light source 21 can form light of any color as well as white light.

[0072] Furthermore, this application also provides a vehicle. The vehicle includes, but is not limited to, passenger cars, buses, trucks, tractor-trailers, special-purpose transport vehicles, and special-purpose vehicles. The vehicle includes a body assembly and the functional glass assembly 200 described in any of the above embodiments.

[0073] The vehicle body components may include sheet metal, accessories, and decorative parts. The functional glass 100 may be a sunroof, door glass, or rear windshield, etc. The functional glass assembly 200 is assembled with the vehicle body components, including but not limited to the functional glass 100 of the functional glass assembly 200 being directly or indirectly fixedly connected to the vehicle body components, and the target light source 21 of the functional glass assembly 200 being directly or indirectly fixedly connected to the vehicle body components.

[0074] In one embodiment where the functional glass 100 includes a first glass plate 10 and a second glass plate 30, one of the first glass plate 10 and the second glass plate 30 can be an outer glass plate and the other can be an inner glass plate. That is, one of the sides of the first glass plate 10 facing away from the second glass plate 30 and the side of the second glass plate 30 facing away from the first glass plate 10 faces the outside of the vehicle and the other faces the inside of the vehicle.

[0075] The features mentioned above in the specification, claims, and drawings can be combined in any way as long as they are meaningful within the scope of this application. The advantages and features described for functional glass 100 are applied accordingly to functional glass assembly 200 and vehicle.
