Description

Technical Field

[0001] The present disclosure generally relates to the field of glass manufacturing technology, and in particular to a glass assembly and a window assembly using the glass assembly. Background Art

[0002] With the rapid development of the automobile industry, as a good medium for conveying information to the interior and / or exterior of the vehicle, lighting glass with decorative patterns has been widely valued by vehicle manufacturers and favored by consumers. The pattern of lighting glass is usually based on enamel or ink to form a pattern area on the glass surface, and the incident light emitted by the light source is projected onto the pattern area, thereby achieving a lighting effect of pattern luminescence.

[0003] Although the presentation of patterns through lighting glass can meet most of the needs of consumers, in some applications, vehicle manufacturers and consumers expect that the pattern is visible only on one surface of the lighting glass and not on the other surface. For example, while the luminous pattern is observed inside the vehicle, some relevant laws and regulations require that the light or luminous pattern emitted by the vehicle to the outside during the driving process will not or will not easily affect the vehicles and pedestrians outside the vehicle. Existing solutions, for example, use a reflective layer on the entire surface of the lighting glass to reflect the light back into the vehicle. However, in order not to affect the driver or passenger's observation of the outside of the vehicle, there are certain requirements for the overall light transmittance of the glass, and the reflective layer will change the transmission of light and may affect the driver or passenger's observation. In addition, when it is necessary to form a luminous pattern, the reflective layer may cause a very obvious reflection effect and affect the sensory experience of the occupants inside the vehicle. Therefore, it is difficult for the above existing solutions to obtain satisfactory results, and there is still a need for further adjustment or improvement in terms of pattern presentation occasions, vehicle driving safety, and privacy. Summary of the invention

DETAILED DESCRIPTION

[0048] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0049] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0050] Herein, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified.

[0051] As used herein, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0052] In this document, unless otherwise specifically defined, the terms "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0053] Herein, the "surface" of a glass body is defined by the plane where the length and width of the glass body are located, and the "edge" is defined by the plane where the length or width and thickness or height of the glass body are located. The "cross section" of a glass component is taken along the thickness or height direction of the glass component. "Pattern" includes any one or combination of words, graphics, symbols, numbers, beacons, trademarks, etc. formed by dots, lines, etc.

[0054] Hereinafter, the glass assembly is described as being applied to vehicle window glass, but it does not exclude that the glass assembly can be applied to environments such as doors, windows, curtain walls, aircraft glass or ship glass. When the glass assembly is described as a vehicle window glass for a vehicle, "outside" and "inside" are directions relative to the vehicle body, "outside" refers to the direction away from the vehicle body, and "inside" refers to the direction facing the vehicle body. It should be understood that the vehicle window glass according to the embodiments of the present disclosure includes but is not limited to the front windshield, rear windshield, sunroof glass, door glass (including front door glass and rear door glass) or corner window glass, and different lighting effects can be provided based on different needs.

[0055] In the various embodiments described, unless otherwise specified, the thickness of the glass is the thickness commonly used in the art, and the thickness of each laminated structure on the glass is applicable to the conventional range and is not limited to that shown in the figure. In addition, although the figure shows flat glass, the glass assembly of the present disclosure may also be curved glass. In various embodiments, it is described as an independent glass body or glass plate, but in some cases not described, the surface of the glass may also use a special coating to improve other properties such as heat insulation and / or comfort.

[0056] As mentioned above, for manufacturers and most vehicle users or passengers, it is hoped that the window glass can be used to achieve lighting effects and / or decorative effects of display patterns, while meeting safe driving and certain relevant laws and regulations, or privacy needs in certain occasions. It should be understood that "safe driving" not only includes that light will not be directed toward the outside of the vehicle through the glass component to affect other vehicles and pedestrians, but also includes that light will not be directed to the inside of the vehicle through the glass component to affect the driver. "Privacy" is usually for people inside the vehicle, that is, the glass component can prevent people outside the vehicle from seeing the situation inside the vehicle (including the lighting effects and / or decorative effects of the display patterns on the window glass), thereby achieving a privacy protection function.

[0057] Some existing schemes, such as Figure 1A The glass assembly 10 shown includes a first glass body 11 and a second glass body 12, and an intermediate layer 13 attaches the first glass body 11 and the second glass body 12 to each other. Figure 1B In the glass assembly 10-1 of another embodiment shown, the intermediate layer includes a first intermediate layer 13a attached to the first glass body 11 and a second intermediate layer 13b attached to the second glass body 12. For example, a pattern 14 formed by enamel or ink is formed on the surface of the second glass body 12, for example, away from the first glass body 11. The incident light emitted by the light source enters the glass assembly 10 or 10-1 and contacts the pattern 14, which is scattered or diffused, and then directed out of the second glass body 12 to achieve a lighting effect or a decorative effect with a pattern. In both embodiments, the reflective layer 15 is arranged on the entire surface of the glass assembly, such as Figure 1A As shown, it is arranged between the intermediate layer 13 and the second glass body 12, or as shown Figure 1BAs shown, it is arranged between the first intermediate layer 13a and the second intermediate layer 13b. When the glass assembly is used for vehicle window glass, and the first glass body 11 faces the outside of the vehicle and the second glass body 12 faces the inside of the vehicle, the reflective layer 15 reflects the incident light entering the glass assembly back to the inside of the vehicle. The inventors realize that, especially for door glass, such as front door glass, the reflective layer covering the entire surface of the glass assembly may have an adverse effect on the driver's observation field of view. In addition, when it is necessary to achieve lighting and / or form a luminous pattern, the reflective layer may cause a very obvious reflection effect and affect the sensory experience of the occupants inside the vehicle.

[0058] To this end, according to the concept of the present disclosure, a glass assembly is proposed, comprising a glass body, the glass body having a first surface and a second surface arranged oppositely; a light emitting area, the light emitting area forms a pattern and is formed on the first surface and / or the second surface and / or the glass body of the glass body, and is configured to allow light to be directed from the light emitting area to the second surface; a light shielding area, the light shielding area is arranged on the first surface, and forms a pattern following the pattern formed by the light emitting area to shield the light from the light emitting area toward the light shielding area. When the glass assembly is configured as a laminated glass, the glass assembly comprises a first glass body, and a second glass body attached to the first glass body through an intermediate layer. The light emitting area forms a pattern and is formed on the surface of the first glass body away from the second glass body and / or inside the first glass body, and / or is formed on the surface of the second glass body away from the first glass body and / or inside the second glass body, and / or is formed between the first glass body and the second glass body, and is configured so that light is guided out of the light emitting area from the second glass body; the light shielding area is arranged on the surface of the first glass body away from the second glass body or is arranged between the light emitting area and the first glass body, and a pattern is formed following the pattern formed by the light emitting area to shield the light from the light emitting area toward the light shielding area.

[0059] Depending on different needs, the light exit area is formed between the first glass body and the second glass body, including being formed on the surface of the first glass body facing the second glass body, or being formed on the surface of the second glass body facing the first glass body, or being formed on the surface of the intermediate layer or in the intermediate layer.

[0060] It should be understood that "following" means that the pattern formed by the light shielding area is roughly the same as or slightly larger than the pattern formed by the light emitting area. By providing a light shielding area corresponding to the pattern formed by the light emitting area, the glass component of the present invention can reduce or avoid the adverse effect of the light at the light emitting area on the other side surface of the glass component while achieving the lighting effect and / or the luminous pattern effect on one side surface. For example, the transmittance T1 of the light shielding area with respect to visible light (390nm to 780nm wavelength range) can be, for example, less than or equal to 70%, less than or equal to 50%, less than or equal to 30%, or less than or equal to 10%, and will not affect the transmittance of other areas of the glass component outside the light shielding area. For occasions where high transmittance is required, such as the front door glass, in the non-shielded area where the light emitting area and the corresponding light shielding area are not provided, the transmittance T2 with respect to visible light can be maintained at, for example, greater than or equal to 50%, or greater than or equal to 70%, ensuring the driver's good observation of the outside of the vehicle. In addition, the glass assembly of the present invention can reduce or avoid the light that provides the lighting effect and / or the decorative effect of displaying the pattern from being directed out of the first surface of the glass body or out of the first glass body. If the first glass body is set to face the outside of the vehicle, it can effectively provide the privacy of the lighting light and / or the luminous pattern and reduce or avoid the impact of the light on other vehicles and pedestrians, thereby providing privacy and safety effects; if the first glass body is set to face the inside of the vehicle, it can reduce or avoid the impact of the lighting light and / or the luminous pattern on the occupants inside the vehicle.

[0061] Specific combination Figure 2A In one embodiment shown in the figure, the glass assembly 100 of the present disclosure includes a glass body 110, and the glass body 110 has a first surface 111 and a second surface 112 arranged oppositely. According to different needs, the glass body 110 can be selected as tempered glass, and the thickness is, for example, about 3 mm to 10 mm. Figure 2AIn the illustrated embodiment, the light exiting area 140 includes dots or lines 141, 142 forming a pattern, which is formed on the second surface 112 of the glass body 110 by laser engraving, printing or film layer, and is configured so that light is guided out of the light exiting area 140 to the second surface 112. In some optional or additional ways, the light exiting area can be formed on the first surface 111 of the glass body 110 by laser engraving, printing or film layer and / or can be formed in the glass body 110 by laser engraving. The light shielding area 150 is, for example, arranged on the first surface 111, and is also formed in accordance with the pattern formed by the light exiting area 140 to shield the light from the light exiting area 140 toward the light shielding area 150. In some embodiments, the pattern formed by the light-emitting area includes at least two patterns, and further optionally, the pattern includes at least two discontinuous patterns. Correspondingly, the pattern formed by the light-shielding area also includes at least two patterns, and further optionally, the pattern includes at least two discontinuous patterns, and is configured to correspond to at least two patterns (further optionally at least two discontinuous patterns) of the light-emitting area one by one, and the light-shielding area is configured to shield the light from the light-emitting area toward the light-shielding area and export it to the first surface. In some embodiments, the light-emitting area and the light-shielding area can be arranged on the same surface of the glass body, for example, both are arranged on the first surface 111 of the glass body 110, and the light-shielding area shields the light from the light-emitting area toward the light-shielding area. Alternatively, the light-shielding area 150 can be configured to include any one of a light-absorbing layer, a switchable film, and a reflective layer. It should be understood that the light-absorbing layer refers to a coating or film layer of a material including a structure and / or chemical composition that can absorb light, usually composed of a variety of elements, compounds or polymers, and when light is irradiated on the material, almost no transmission and reflection occurs, such as a carbon black material. The light absorbing layer can be attached to the first surface 111 of the glass body 110 by coating or bonding, for example. A switchable film refers to a film layer that can be switched on demand to achieve a transparent state or an opaque state, such as a dimming film of any one of polymer dispersed liquid crystal (PDLC), polymer network liquid crystal (PNLC), guest-host liquid crystal (GHLC), and electrochromic (EC), which has a certain haze and / or low light transmittance when switched to an opaque state. The switchable film can be attached to the first surface 111 of the glass body 110 by bonding, for example. The reflective layer refers to a coating or film layer that can change the transmittance of light in a certain wavelength range by reflection, for example, it can be attached to the first surface 111 of the glass body 110 by coating, plating, bonding, etc., and may include one or more layers of metal, alloy or metal compound. Alternatively, the material of the reflective layer may include but is not limited to silver, aluminum, rhodium, and molybdenum.

[0062] It should be understood that the number, size, distribution and positional relationship of the patterns formed in the light-emitting area 140 are merely examples. Depending on different needs, multiple numbers and sizes of patterns, as well as uniform or uneven arrangements are feasible, thereby producing different display patterns or lighting effects through different designs.

[0063] Figure 2B In the embodiment of the laminated glass shown, the glass assembly 100-1 includes a first glass body 110 and a second glass body 120, and an intermediate layer 130 attaches the first glass body 110 and the second glass body 120 to each other. In this embodiment, the first glass body 110, for example, faces the outside of the vehicle and can be called the outer glass, and the second glass body 120, for example, faces the inside of the vehicle and can be called the inner glass. The intermediate layer 130 is, for example, a bonding layer suitable for laminated glass such as polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA). According to different needs, the first glass body 110 can be any one of ordinary glass, ultra-transparent glass, and tinted glass, and the intermediate layer 130 can be a transparent or tinted material, including but not limited to any one of the above-mentioned PVB, EVA, polyphenylene ester (POB), and optically clear adhesive (OCA), and the thickness can be selected from about 0.38 mm to 1.14 mm. The second glass body 120 can be ordinary glass or ultra-transparent glass, preferably ultra-transparent glass. The thickness of the first glass body 110 and the second glass body 120 may be selected to be approximately 1.1 mm to 6 mm (such as tempered glass, heat-strengthened glass or annealed glass), or approximately 0.7 mm to 1.6 mm (such as chemically strengthened glass).

[0064] According to different needs, the light-emitting area can be formed on the surface of the first glass body away from the second glass body and / or in the first glass body, and / or on the surface of the second glass body away from the first glass body and / or in the second glass body, and / or between the first glass body and the second glass body. Here, "between" covers various arrangements in which the light-emitting area is directly adjacent to or not directly adjacent to the first glass body or the second glass body, for example, the light-emitting area is formed on the surface of the first glass body facing the second glass body, or on the surface of the second glass body facing the first glass body, or on the surface of the intermediate layer or in the intermediate layer. According to different needs, the light-emitting area can be constructed to include a light extraction layer and / or an active light-emitting layer. It should be understood that the "light extraction layer" is a layer structure having a light extraction structure such as a microstructure or a microtexture, and the size of the light extraction structure is in the micrometer or even nanometer level. "Active light-emitting layer" refers to a layer structure that can emit light by itself when powered on without a light source. For example, any one of OLED (organic light-emitting diode), Mirco LED, Mini LED, and EL (electroluminescence) can be used. When a light extraction layer is used, the light in the light emitting area comes from the light emitted by the light source, which is a passive light emitting method; when an active light emitting layer is used, the light in the light emitting area comes from the light emitted by the active light emitting layer itself, which is an active light emitting method.

[0065] Figure 2B In the illustrated embodiment, the light emitting area 140 is, for example, a light extraction layer formed on the surface of the second glass body 120 away from the first glass body 110 by laser engraving or printing or a film layer, or an active light emitting layer arranged on the surface of the second glass body 120 away from the first glass body 110, for example, a surface facing the interior of the vehicle. For printing, the light extraction layer can be printed on the surface of the second glass body 120 by screen printing or inkjet printing. For the film layer, the light extraction layer can be adhered to the surface of the second glass body 120 by a light extraction film. The incident light emitted by the light source (such as an LED light strip or a point-shaped LED with a light guide) disposed at the edge of the glass component (such as the edge of the second glass body 120) or embedded in the glass component (such as embedded in the second glass body 120) enters the glass component 100-1 and contacts the light extraction layer, which is scattered or diffused, and then is led out of the second glass body 120 to achieve a lighting effect or a decorative effect with a light emitting pattern. For the active light emitting layer, the light emitted by the active light emitting layer is directly led out from the active light emitting layer.

[0066] Alternatively, the light shielding area 150 may be configured to include any one of a light absorbing layer, a switchable film, and a reflective layer. According to different needs, the light shielding area may be arranged on the surface of the first glass body away from the second glass body, or between the intermediate layer and the first glass body or the second glass body, or in the intermediate layer, and may be optionally implemented by, for example, coating a light absorbing material.

[0067] Figure 2B In the illustrated embodiment, the light shielding region 150 is exemplarily arranged between the intermediate layer 130 and the second glass body 120, that is, arranged on the surface of the second glass body 120 facing the first glass body 110 or the surface of the intermediate layer 130 facing the second glass body 120; optionally, the light shielding region 150 may be arranged between the intermediate layer 130 and the first glass body 110, that is, arranged on the surface of the first glass body 110 facing the second glass body 120 or the surface of the intermediate layer 130 facing the first glass body 110; or the light shielding region 150 is optionally arranged in the intermediate layer 130. For example, when a switchable film is used, it can be arranged on the surface of the second glass body 120 facing the first glass body 110 by bonding or laminating with the help of the intermediate layer 130. When a reflective layer is used, it can be arranged on the surface of the second glass body 120 facing the first glass body 110 by coating, plating, bonding, etc., or the switchable film or reflective layer is sandwiched between two initial intermediate layers and combined to form an intermediate layer with a light shielding area, so as to shield the light from the light emitting area 140 toward the light shielding area 150, and prevent the light from the light emitting area 140 from being output from the first glass body 110. In this way, for the people inside the vehicle, the lighting effect or the decorative effect of the luminous pattern can be observed from the side of the second glass body 120, while the lighting effect or the luminous pattern will not or is not easy to be observed on the side of the first glass body 110 facing the outside of the vehicle, which can play a role in protecting the privacy of the lighting light and / or the luminous pattern. At the same time, because the lighting light or the luminous pattern will not or is not easy to affect the vehicles and pedestrians outside the vehicle, it can also meet the requirements of certain relevant laws and regulations. It should be understood that when the first glass body 110 is arranged to face the interior of the vehicle, the lighting effect or luminous pattern produced by the illustrated arrangement is for people outside the vehicle, and the passengers inside the vehicle will not be affected by the lighting light or luminous pattern, thereby enhancing the driving experience. The following exemplary embodiments will be described with the first glass body arranged to face the exterior of the vehicle as an example, but various applications in which the first glass body is arranged to face the interior of the vehicle are not excluded.

[0068] As mentioned above, "following" means that the pattern formed by the light shielding area is substantially the same as or slightly larger than the pattern formed by the light emitting area. Accordingly, the glass assembly can be constructed to satisfy:

[0069] D1+d×tanθ≤D2≤D1+3d×tanθ.

[0070] Combination Figure 2AAs shown, D1 is the size of the pattern formed by the light emitting area 140 along the surface direction of the glass component 100; D2 is the corresponding size of the pattern formed by the light shielding area 150 along the surface direction of the glass component 100 following the light emitting area; d is the distance between the light emitting area 140 and the light shielding area 150 along the cross-sectional direction of the glass component 100, which is approximately the thickness of the glass body 110 in the embodiment shown; θ is the critical angle of total reflection of light in the glass component. Here, the sizes of D1 and D2 are measured by the sizes of the points, lines, etc. that form the pattern, such as the line width diameter (line diameter) and / or line length of the line form of the pattern. When the size D1 of the pattern formed by the light emitting area is determined, the size D2 of the light shielding area corresponding to the pattern can be set accordingly. In addition, when the stacked structure of the glass component is determined and the light source arrangement method is determined, the critical angle θ can also be determined. In this way, depending on the different stacking structures of the glass assembly, the dimension D2 of the light shielding area 150 along the surface direction of the glass assembly 100 can be substantially the same as or slightly larger than the dimension D1 of the pattern formed by the light emitting area 140 along the surface direction of the glass assembly 100, which can effectively meet the light shielding effect. In some embodiments, the glass assembly can be constructed to meet: D1≤D2≤D1+6mm.

[0071] Advantageously, the area of ​​the light emitting region 140 and the area of ​​the light shielding region 150 account for less than or equal to 70%, less than or equal to 50%, less than or equal to 30%, or less than or equal to 10% of the surface area of ​​the glass body 110 .

[0072] Combination Figure 2B In the manner shown, d is the distance between the light emitting area 140 and the light shielding area 150 along the cross-sectional direction of the glass component 100-1, which is approximately the thickness of the second glass body 120 in the embodiment shown. In some embodiments, the light shielding area 150 can be arranged between the intermediate layer 130 and the first glass body 110, and accordingly, d is the distance between the light emitting area 140 and the light shielding area 150 along the cross-sectional direction of the glass component, that is, approximately the sum of the thickness of the intermediate layer 130 and the second glass body 120. The glass component can also obtain similar effects as described above, which will not be described in detail here.

[0073] Advantageously, the area of ​​the light emitting region 140 and the area of ​​the light shielding region 150 account for less than or equal to 70%, less than or equal to 50%, less than or equal to 30%, or less than or equal to 10% of the surface area of ​​the first glass body 110 or the second glass body 120, respectively.

[0074] In some embodiments, the light shielding area can be arranged on a surface of the first glass body 110 away from the second glass body 120, such as Figure 2CIn the illustrated embodiment, a light shielding region 150 is disposed on the surface of the first glass body 110 of the glass assembly 100-2 away from the second glass body 120. In this manner, with respect to the above formula, d is the distance between the light emitting region 140 and the light shielding region 150 along the cross-sectional direction of the glass assembly 100-2, which is approximately the sum of the thicknesses of the first glass body 110, the intermediate layer 130, and the second glass body 120 in the illustrated embodiment.

[0075] In some embodiments, the glass assembly includes a colored layer composed of the first glass body and / or any layer or layers between the first glass body and the light exit area. Further optionally, the glass assembly may include a colored layer composed of the first glass body and / or the intermediate layer. In other words, depending on different needs, the colored layer may be a single-layer structure (for example, the first glass body or the intermediate layer) or a double-layer structure (for example, the first glass body and the intermediate layer) or a multi-layer structure (for example, the first glass body and multiple intermediate layers). It should be understood that the "colored layer" refers to a layer structure with color, or a translucent or opaque layer structure, and the colored layer has a lower light transmittance than a transparent layer structure. The light transmittance of the colored layer is the product of the individual light transmittances of all the layers included. The so-called "coloring" refers to the inherent color inside the colored layer (whether it is naturally colored or has color added through a process) in a natural state (for example, non-electrically controlled and variable). In some embodiments, the first glass body and / or the intermediate layer itself may or may not have color, and the first glass body and / or the intermediate layer may be directly attached (e.g., pasted, pressed, etc.) with a colored film or coated with a colored coating, such as a colored film of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), etc., to form the colored layer. Advantageously, the transmittance T3 of the colored layer with respect to visible light is less than or equal to 70%, less than or equal to 50%, less than or equal to 30%, or less than or equal to 10%. By providing a colored layer, the glass assembly can be further protected from the privacy of the lighting light and / or the luminous pattern, and in the case where the first glass body is arranged to face the outside of the vehicle, the light or the luminous pattern can be further prevented from or not easily affecting vehicles and pedestrians outside the vehicle, and the requirements of certain relevant laws and regulations can be met. Since the light shielding area limits the light output from the light exiting area toward the light shielding area, the colored layer can have a relatively large transmittance (for example, greater than or equal to 50%, greater than or equal to 70%) without hindering the transmission of visible light. For example, optionally, the difference between the transmittance T3 of the colored layer with respect to visible light and the transmittance T1 of the light shielding area with respect to visible light is greater than or equal to 20%, greater than or equal to 30%, greater than or equal to 40%, or greater than or equal to 50%. For example, optionally, the product of the transmittance T3 of the colored layer with respect to visible light and the transmittance T1 of the light shielding area with respect to visible light is less than or equal to 70%, less than or equal to 50%, less than or equal to 30%, or less than or equal to 10%, so as to, for example, not affect the safety needs of the driver inside the vehicle to observe the outside of the vehicle during driving, which is beneficial to the application of door glass in particular.

As described above, in an optional embodiment, the intermediate layer 130 may also be configured as a colored layer, or both the first glass body 110 and the intermediate layer 130 may be configured as colored layers. When the light emitting area 140 is configured as an active light emitting layer, the second glass body 120 may also be configured as a colored layer.

Figure 2B As mentioned above, the light shielding area 150 may also be arranged in the first intermediate layer 130a or in the second intermediate layer 130b. Figure 2E In the illustrated embodiment, at least one functional layer may be provided between the light emitting area 140 and the light shielding area 150, and in this embodiment, a functional layer 160 is exemplarily shown. Depending on different needs, the functional layer 160 may include, for example, but is not limited to, a light guide layer, an adhesive layer, an imaging layer, a display layer, a heat insulation layer, and a touch layer. Optionally, the light guide layer may be any one of glass, PVB, polycarbonate (PC), and PET. Accordingly, with respect to the above formula, d is the distance between the light emitting area 140 and the light shielding area 150 along the cross-sectional direction of the glass component 100-4, which is approximately the sum of the thicknesses of the functional layer 160, the second intermediate layer 130b, and the second glass body 120 in the illustrated embodiment.

When the light-emitting region 140 is configured as an active light-emitting layer, the second glass body 120 may also be configured as a colored layer.

Optionally, the intermediate layer 230 can also be configured as a colored layer. Figure 2BThe difference between the illustrated embodiments is that the light emitting region 240 is, for example, a light extraction layer formed on the surface of the second glass body 220 facing the first glass body 210 by laser engraving or printing or in the form of a film layer, or the light emitting region 240 is, for example, a light extraction layer formed on the surface of the intermediate layer 230 facing the second glass body 220 by printing, or the light emitting region 240 is, for example, an active light emitting layer sandwiched between the first glass body 210 and the second glass body 220, for example, sandwiched between the intermediate layer 230 and the second glass body 220. In this embodiment, the light shielding region 250 may be arranged between the intermediate layer 230 and the first glass body 210. Accordingly, with respect to the above formula, d is the distance between the light emitting region 240 and the light shielding region 250 along the cross-sectional direction of the glass assembly 200, which is approximately the thickness of the intermediate layer 230 in the illustrated embodiment.

Accordingly, with respect to the above formula, d is the distance between the light emitting area 240 and the light shielding area 250 along the cross-sectional direction of the glass component 200-1, and in the illustrated embodiment, it is approximately the sum of the thicknesses of the functional layer 260 and the intermediate layer 230. In this embodiment, the first glass body 210 is configured as a colored layer. Optionally, any one or more layers of the first glass body 210, the intermediate layer 230, and the functional layer 260 may also be configured as a colored layer.

Accordingly, with respect to the above formula, d is the distance between the light emitting area 240 and the light shielding area 250 along the cross-sectional direction of the glass component 200-2, which is approximately the sum of the thickness of the functional layer 260 and the second intermediate layer 230b in the illustrated embodiment.

Optionally, any one or more layers from the first glass body 210 to the second intermediate layer 230b can also be configured as a colored layer, that is, any one or more layers of the first glass body 210, the first intermediate layer 230a, the functional layer 260, and the second intermediate layer 230b can be configured as a colored layer.

[0083] Figure 4A Another embodiment of a glass assembly 300 is shown, wherein the glass assembly 300 includes a first glass body 310 and a second glass body 320, wherein the intermediate layer includes a first intermediate layer 330a attached to the first glass body 310 and a second intermediate layer 330b attached to the second glass body 320, and the first glass body 310 is configured as a colored layer. Optionally, the first intermediate layer 330a may be configured as a colored layer, or both the first glass body 310 and the first intermediate layer 330a may be configured as colored layers. In this embodiment, the light emitting area 340a may be configured as a light extraction layer or an active light emitting layer sandwiched between the first glass body and the second glass body in the form of a film layer. Similarly, the "between" here covers various arrangements in which the light extraction layer or the active light emitting layer is directly adjacent to or not directly adjacent to the first glass body or the second glass body. Figure 4B Another embodiment of the glass assembly 300-1 is shown with Figure 4A The glass assembly 300 shown is similar. In both shown embodiments, the light exit region 340a is arranged between the first intermediate layer 330a and the second intermediate layer 330b and can be configured as a light extraction layer. The light extraction structure can be, for example, a protrusion ( Figure 4B ) and / or a notch recessed toward the first glass body 310 ( Figure 4A ) and other micro-textures and form a light extraction layer. In the two illustrated embodiments, the light emitting region 340a may be directly adjacent to the light shielding region 350, that is, the light shielding region 350 is arranged between the first intermediate layer 330a and the second intermediate layer 330b, and no other layer is arranged between the light emitting region 340a and the light shielding region 350. In some embodiments, the light emitting region 340a may also be a light extraction layer formed on the surface of the second intermediate layer 330b facing the first glass body 310 by printing, such as Figure 4C The glass assembly 300-2 and Figure 4D The glass component 300-3 of the illustrated embodiment. Similarly, in the two illustrated embodiments, the light emitting area 340a may be directly adjacent to the light shielding area 350, that is, no other layer is provided between the light emitting area 340a and the light shielding area 350. Accordingly, with respect to the above formula, d is the distance between the light emitting area 340a and the light shielding area 350 along the cross-sectional direction of the glass components 300, 300-1, 300-2, and 300-3, which may be substantially zero in the illustrated embodiment. In this manner, the dimensions of the light shielding area 350 and the light emitting area 340a in the direction along the surface of the glass component 300 may be substantially the same.

[0084] exist Figure 4E In another embodiment of the glass assembly 300-4, Figure 4A The difference between the illustrated embodiment is that at least one functional layer may be provided between the light emitting area 340b and the light shielding area 350, and in this embodiment, a functional layer 360 is exemplarily shown. In addition, in addition to the first glass body 310 being configured as a colored layer, the first intermediate layer 330a is also configured as a colored layer. Optionally, only the first intermediate layer 330a may be configured as a colored layer, or only the first glass body 310 may be configured as a colored layer. Further, optionally, the functional layer 360 may also be configured as a colored layer, which will not be repeated here. In this embodiment, the light emitting area 340b may be configured as an active light-emitting layer sandwiched between the first intermediate layer 330a and the second intermediate layer 330b. Accordingly, with respect to the above formula, d is the distance between the light emitting area 340b and the light shielding area 350 along the cross-sectional direction of the glass component 300-4, which is approximately the thickness of the functional layer 360 in the illustrated embodiment.

[0085] Figure 5 Another embodiment of a glass assembly 400 is shown, the glass assembly 400 includes a first glass body 410 and a second glass body 420, an intermediate layer 430 attaches the first glass body 410 and the second glass body 420 to each other, a light shielding area 450 is arranged between the intermediate layer 430 and the second glass body 420, and the first glass body 410 is configured as a colored layer. Figure 2B The difference between the illustrated embodiment is that the light emitting area 440 is, for example, constructed as a light extraction layer formed in the second glass body 420 by laser engraving. Similarly, in an optional embodiment, the intermediate layer 430 may also be constructed as a colored layer, or both the first glass body 410 and the intermediate layer 430 may be constructed as colored layers. Correspondingly, with respect to the above formula, d is the distance between the light emitting area 440 and the light shielding area 450 along the cross-sectional direction of the glass component 400. In the illustrated embodiment, since the light emitting area 440 is in the second glass body 420, the measurement of d is more complicated, and d can be roughly regarded as zero. In this way, the dimensions of the light shielding area 450 and the light emitting area 440 in the direction along the surface of the glass component 400 can be roughly the same.

[0086] Fig. 6A Another embodiment of a glass assembly 500 is shown, the glass assembly 500 includes a first glass body 510 and a second glass body 520, an intermediate layer 530 attaches the first glass body 510 and the second glass body 520 to each other, a light shielding region 550 is arranged between the intermediate layer 530 and the first glass body 510, and the first glass body 510 is configured as a colored layer. Figure 3AThe difference between the illustrated embodiments is that the light-emitting region 540 is, for example, constructed as a light extraction layer embedded in the intermediate layer 530 by material mixing or printing or film layer. For example, when the intermediate layer 530 is made of PVB material, two initial intermediate layers can be provided, and materials such as enamel can be printed on one surface of the initial intermediate layer by screen printing or inkjet printing to form a pattern, and then the sheets are combined to form an intermediate layer with a light extraction layer inside. In some embodiments, scattering particles can be mixed in when making the intermediate layer, and the particle size of the scattering particles is at the micron or even nanometer level, so as to form an intermediate layer with a light extraction layer. Scattering particles are, for example, glass microspheres, hollow glass microspheres, titanium dioxide particles, etc. In some embodiments, the light-emitting region 540 can be, for example, constructed as an active light-emitting layer embedded in the intermediate layer 530 by material mixing or film layer. For example, an electroluminescent material can be mixed into the intermediate layer material to obtain an intermediate layer with an active light-emitting layer. Correspondingly, regarding the above formula, d is the distance between the light emitting area 540 and the light shielding area 550 along the cross-sectional direction of the glass component 500. In the illustrated embodiment, since the light emitting area 540 is located in the middle layer 530, and the thickness of the middle layer 530 is relatively thin, for example, the thickness can be selected to be about 0.38 mm to 1.14 mm as described above, and the calculation of d is relatively complicated, d can be roughly regarded as zero. In this way, the dimensions of the light shielding area 550 and the light emitting area 540 along the surface direction of the glass component 500 can be roughly the same.

[0087] exist Figure 6B In another embodiment of the glass assembly 500-1, Fig. 6AThe embodiment shown is different in that the intermediate layer includes a first intermediate layer 530a attached to the first glass body 510 and a second intermediate layer 530b attached to the second glass body 520, the light shielding area 550 is arranged between the first intermediate layer 530a and the second intermediate layer 530b, and the light emitting area 540 is constructed as a light extraction layer embedded in the second intermediate layer 530b by material mixing or printing or film layer. In addition, in addition to the first glass body 510 being constructed as a coloring layer, the first intermediate layer 530a is also constructed as a coloring layer. Optionally, only the first intermediate layer 530a can be constructed as a coloring layer, or only the first glass body 510 can be constructed as a coloring layer. In some embodiments, the light emitting area 540 can be constructed as an active light-emitting layer embedded in the second intermediate layer 530b by material mixing or film layer. Correspondingly, regarding the above formula, d is the distance between the light emitting area 540 and the light shielding area 550 along the cross-sectional direction of the glass component 500-1. Similarly, since the light emitting area 540 is located in the second intermediate layer 530b, and the thickness of the second intermediate layer 530b is relatively thin, and the measurement of d is relatively complicated, d can be roughly regarded as zero in the illustrated embodiment. In this way, the dimensions of the light shielding area 550 and the light emitting area 540 along the surface direction of the glass component 500-1 can be roughly the same.

[0088] It can be seen from the above description that no matter what kind of arrangement is used, the glass assembly of the present invention provides a light emitting area and a light shielding area, and the light shielding area forms a pattern following the pattern formed by the light emitting area to shield the light from the light emitting area toward the light shielding area. The light can be exported to one side surface of the glass assembly through the light emitting area, and the light shielding area can limit the light from the light emitting area to be exported to the other side surface of the glass assembly. While achieving the lighting effect and / or the luminous pattern display effect, it will not affect the overall light transmittance of the remaining areas of the glass assembly. When applied to vehicle doors and windows, it can ensure driving safety, and can meet the requirements of privacy and certain relevant laws and regulations, and has the beneficial effects of simple process and obvious performance improvement.

[0089] It should be understood that in possible embodiments that have been described or not described, various improvements can be used independently or in combination. For example, the light extraction layer and the active light-emitting layer in each of the above embodiments can be used simultaneously to form a light-emitting area, for example, distributed in different areas along the surface direction of the glass component. For another example, the light extraction layer can be formed on the surface of the first glass body away from the second glass body by laser engraving or printing or in the form of a film layer and / or formed in the first glass body by laser engraving, and / or the active light-emitting layer can be arranged on the surface of the first glass body away from the second glass body, and / or the light extraction layer is formed on the surface of the first intermediate layer by printing and / or embedded in the first intermediate layer by material mixing or printing or in the form of a film layer, and / or the active light-emitting layer is embedded in the first intermediate layer by material mixing or in the form of a film layer, as long as the light shielding area can shield the light from the light emitting area toward the light shielding area. The glass component disclosed in the present invention can be applied to a variety of occasions to meet the diverse needs of users.
