[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] In one embodiment of the present application, please refer to Figure 1 , which is a schematic diagram of a glass assembly that can provide lighting function according to an embodiment of the present application; as shown in the figure, the glass assembly 1 that can provide lighting function according to the present embodiment is mainly used on windows of various vehicles, including but not limited to automobile glass sunroofs, automobile glass side windows, rail transit train side windows, ship portholes, sightseeing windows, etc. The glass assembly 1 that can provide lighting function according to the present embodiment includes a glass component 2, a light-emitting component 3 and a reflective layer 4. The glass component 2 has an inner layer of glass 21 and an outer layer of glass 22. The inner layer of glass 21 and the outer layer of glass 22 are arranged opposite to each other, such as Figure 1 As shown, the inner layer of glass 21 is located on the left side of the glass assembly 2, and the outer layer of glass 22 is located on the right side of the glass assembly 2. The inner layer of glass 21 and the outer layer of glass 22 are opposite to each other on the left and right. In this embodiment, the inner layer of glass 21 and the outer layer of glass 22 are single-layer glass. In some other embodiments, the inner layer of glass 21 and the outer layer of glass 22 can be multi-layer glass.

[0022] See also Figure 1 The light-emitting component 3 is arranged on the inner glass 21, and the light-emitting component 3 includes a light-guiding layer 31 and a light-emitting member 32. The light-guiding layer 31 is arranged on a side adjacent to the inner glass 21 and the outer glass 22. Figure 1 As shown, the light guide layer 31 is located on the right side of the inner glass 21. The light guide surface of the light guide layer 31 faces the inner glass 21, and the light emitting element 32 is arranged on the side of the light guide layer 31. In this embodiment, the light emitting element 32 is arranged on the upper and lower sides of the light guide layer 31. In some other embodiments, the light emitting element 32 can also be arranged on one or more sides of the light guide layer 31. Different visual and display effects can be achieved by arranging the light emitting element 32 in different positions. The light emitting element 32 is mainly used to provide a lighting source. In this embodiment, the light emitting element 32 is a linear light source, for example, the light emitting element 32 uses an LED light strip, that is, an array of LED light emitting diodes, but is not limited to this. The light-emitting surface of the light-emitting component 32 faces the inner side of the light-guiding layer 31 to emit light into the light-guiding layer 31. The light-guiding layer 31 is mainly used to convert the light source of the light-emitting component 32 into a uniform surface light source. In the present embodiment, the light-guiding layer 31 is a nano-light-guiding plate. The nano-light-guiding plate adopts nano-scale light-scattering material. The surface thereof does not require screen printing of dots and has high transparency. It realizes efficient conversion of point and line light sources into surface light sources, improves the transparency of the glass component 2, and has a wide and unrestricted field of view.

[0023] See also Figure 1 The reflective layer 4 is disposed on the outer glass 22 and is located on the side where the outer glass 22 is adjacent to the inner glass 21. Figure 1 As shown, the reflective layer 4 is located on the left side of the outer glass 22. The reflective layer 4 is configured to reflect the light leaked from the light guide layer 31. In this embodiment, the reflective layer 4 is a semi-reflective and semi-transparent film, which is characterized in that the reflectivity is much greater than the transmittance from the inside to the outside in the reflection direction; the transmittance is much greater than the reflectivity from the outside to the inside in the transmission direction. Therefore, the light inside the glass component 2 can be reflected into the car through the semi-reflective and semi-transparent film, and the light outside the car can enter the car through the semi-reflective and semi-transparent film of the reflective layer, thereby reducing the loss of light and enhancing the lighting brightness of the luminous glass. When not used as a lighting function component, the semi-reflective and semi-transparent film does not block the entry of external light, and plays the role of the window glass, thereby improving the transparency of the car.

[0024] See also Figure 2 , which is a lighting schematic diagram of a glass assembly that can provide lighting function according to an embodiment of the present application, and the black arrow between the inner glass 21 and the reflective layer 4 is the refraction path of the leaked light; as shown in the figure, when the glass assembly 1 that can provide lighting function according to the present embodiment is illuminated, the light emitting member 32 provides a lighting light source, and the light enters the light guiding layer 31, and the light guiding layer 31 converts it into a uniform surface light source, so that the light is evenly and softly irradiated on the inner glass 21, providing a soft lighting effect and enhancing the sense of atmosphere, however, when the light guiding layer 31 converts the light source, there is usually a part of the leaked light on the back side of the light guiding layer 31, and these lights are emitted to the outer glass 22, and the reflective layer 4 reflects these lights back to make them emit to the inner glass 21, thereby reducing the loss of light and enhancing the lighting brightness and lighting effect.

[0025] The structure of the glass assembly 2 is further described below. Figure 1 and Figure 2 The glass assembly 2 also has a spacing frame bar 23, one end of the spacing frame bar 23 is arranged on the light guide layer 31, and the other end of the spacing frame bar 23 is arranged on the outer glass 22. A hollow layer 24 is formed between the outer glass 22, the spacing frame bar 23 and the light guide layer 31. Specifically, the light guide layer 31 is bonded to the right side of the inner glass 21 through a full bonding process, and the light guide layer 3 and the inner glass 21 form a first double-layer composite structure. The reflective layer 4 is bonded to the left side of the outer glass 22 through a full bonding process, and the reflective layer 4 and the outer glass 22 form a second double-layer composite structure. The first double-layer composite structure forms a hollow structure with the second double-layer composite structure through a fixing process of the spacing frame bar 23, forming a hollow layer 24. The reflective layer 4 is located in the spacing frame bar 23 and the hollow layer 24. In this embodiment, the hollow layer 24 is also filled with an inert gas, and the inert gas can use argon or xenon, but is not limited thereto.

[0026] See also Figure 1 and Figure 2 The glass assembly 2 also has a glass edging 25, which is coated on the edge of the glass assembly 2 to make the glass assembly 2 have better sealing and good appearance, and can also reduce wind noise. At the same time, the light-emitting component 32 is located in the glass edging 25 to ensure that the light of the light-emitting component 32 does not leak out. In this embodiment, the glass edging 25 is made of polyurethane (PU), thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC) or polypropylene (PP), and is formed on the edge of the glass assembly 2 by injection molding, but is not limited to this.

[0027] In summary, the present application provides a glass assembly that can provide lighting function, wherein a light-guiding layer is arranged on the side where the inner layer of glass is adjacent to the outer layer of glass, and a reflective layer is arranged on the outer layer of glass, so that the light-emitting component converts its light source into a uniform surface light source through the light-guiding layer, so that the light is evenly and softly irradiated on the inner layer of glass, providing a soft lighting effect to enhance the sense of atmosphere, and at the same time, the reflective layer can reflect the light leaked from the light-guiding layer back, thereby reducing the loss of light and enhancing the lighting brightness and lighting effect.
