It is understood that vehicle windows according to embodiments of the present invention, including but not limited to front windshields, rear windshields, roof windows, door windows, or quarter windows, may provide different lighting effects based on different needs.

In the automobile industry, which is changing day by day, glass assemblies with lighting and decorative effects have been widely used in, for example, vehicle skylights of medium and high-grade vehicles, and not only can the effects of light brightness and/or color change be realized, but also illumination effects with different patterns can be formed by combining with coatings and/or sandwich structures. The prior art mostly uses light extraction technology based on enamel or ink coating on the surface of glass, or uses light extraction film or light guide film laminated into the glass to form a pattern area, or Light Emitting Diode (LED) technology integrated into the glass, however, the above prior art is not satisfactory for manufacturers and users with respect to the requirement of pattern brightness after the light source is turned on and the market demand that the pattern is not obvious or visible in the off state of the light source.

The applicant realizes that the carved luminescent glass is widely applied to the building field and the daily life field, such as luminescent stair handrails, luminescent building exterior wall glass, luminescent billboards (made of transparent materials such as glass and polymethyl methacrylate (PMMA)) and the like, but is rarely applied to automobile glass. In addition, the carving pattern on the luminous glass is mainly carved on the surface of the glass to realize the luminescence. The applicant finds that the formation of the microstructure inside the glass not only can provide a relatively high-brightness illumination effect, which is helpful for meeting the above market demands, but also has the beneficial effects of environmental protection, energy conservation and the like.

The utility model discloses it improves to glass assembly just based on above-mentioned design. In various described embodiments, a glass assembly includes a first glass body, a second glass body, and a light extraction structure having a light extraction surface disposed within the second glass body. Here, the light extraction surface refers to a light exit structure surface on the light extraction structure, which has a significantly changed exit angle or direction of light, wherein the surface of the light exit structure surface may be formed in a plane or non-plane, such as a semi-sphere, a cone, a triangle, a trapezoid, and the like. When light contacts a partial or entire light extraction surface on the light extraction structure, the light is reflected, scattered, or diffused to present an illumination effect. The light extraction structures may be arranged continuously or discontinuously, or with different distributions to produce different display patterns or display effects. Also, the light extraction surface may be disposed continuously or discontinuously over the light extraction structure. In addition, depending on the micro texture or pattern that the light extraction structure constitutes, the utility model also provides an illumination effect, that is to say, when the light source is opened, the glass subassembly presents required pattern or display effect, when the light source is closed, then makes the glass subassembly have different transparent effects according to the texture line footpath of light extraction structure, transparent or translucent promptly. This is particularly advantageous for the lighting requirements of vehicle windows, such as vehicle sunroofs.

According to the utility model discloses, the light extraction structure is formed in the second vitreous body through the laser sculpture. So-called laser engraving, i.e. 3D laser engraving glass technology, the laser generates a pulse in a very short time, the energy of which can instantaneously heat and crack the glass body, thereby generating a very small white spot, engraving a predetermined shape in the glass, and the rest of the glass body is kept intact. The laser engraving is adopted, the laser beam is engraved in the glass, no dust, no volatile substances, no emissions and no consumables are generated, no pollution is generated to the external environment, and compared with the traditional technology of forming a light extraction structure on the surface of the glass by sand blasting engraving, screen printing, etching and the like, the working environment of workers can be greatly improved. In addition, the laser has low energy consumption and also has the advantage of energy conservation.

Fig. 1 and 2 show a glass assembly 100 according to an embodiment of the present invention, the glass assembly 100 comprising a first glass body 110 having a first surface 111 and a second surface 112, and a second glass body 120 having a third surface 121 and a fourth surface 122. For the window glass, the first glass body 110 may be referred to as an outer glass, and the second glass body 120 may be referred to as an inner glass. The intermediate layer 130 is sandwiched between the first glass body 110 and the second glass body 120 to bond the two together. The interlayer 130 is, for example, polyvinyl butyral (PVB) or Ethylene Vinyl Acetate (EVA). In the second glass body 120, a light extraction structure 140 having a light extraction surface 141 is formed in a desired pattern by laser engraving. It is to be understood that the light extraction structures are microstructures or microtextures, with dimensions on the micrometer or even nanometer scale. Depending on different design requirements, the light extraction surface 141 of the light extraction structure 140 may be arranged towards the first glass body 110 or the second glass body 120 with the aim of causing incident light directed into the second glass body 120 to be extracted at the light extraction structure and tend to be directed out of the fourth surface 122, the light extraction surface 141 being exemplarily shown in the form of a triangular cusp in fig. 1 and 2 and being arranged towards the fourth surface 122 of the second glass body 120, thereby achieving an improved pattern display effect while achieving a lighting effect inside the vehicle. As shown by the arrows in fig. 1, the incident light guided into the second glass body 120 is totally reflected in the second glass body 120, and when the incident light contacts the microstructure or the light extraction surface 141 locally generated on the bottom surface of the light extraction structure 140 facing the fourth surface of the pattern to be illuminated, the light is reflected, scattered, or diffused and a part of the light is guided out from the fourth surface 122 to realize the illumination effect. In the manner shown in fig. 2, light contacts the locally generated microstructures on the top surface of the light extraction structure 140 facing the third surface, and also reflects, scatters or diffuses the light and a portion of the light is directed out of the fourth surface 122 to achieve an illumination effect.

With the above design, a light extraction structure is disposed within the second glass body in the glass assembly, and incident light entering the second glass body is reflected, scattered, or diffused by the light extraction structure and directed out of the fourth surface of the second glass body after reaching the light extraction structure. The light extraction structure forms through laser sculpture, so, the utility model discloses a glass subassembly has strengthened the illuminating effect on the inside glass with environmental protection and energy saving and low-cost mode, not only can realize high automation. The system can also realize standardized, digitalized and networked production, or realize remote monitoring and operation, effectively reduce the labor intensity of workers, improve the working environment and greatly improve the production efficiency and the product grade. Depending on different application requirements, the light extraction structures formed by laser engraving may produce different display patterns or display effects, such as stars, moon, etc., with different distributions.

It is to be understood that reflection, scattering or diffusion of light rays occurring after contacting the light extraction structures does not preclude transmission of light rays towards the first glass body. In some embodiments, an intermediate layer 130 having a gray scale, such as a gray scale PVB, can be used to block light, such as when the glass assembly is applied to a vehicle window, to prevent incident light for illumination from exiting toward the first glass body after contacting the light extraction structure, thereby affecting the illumination effect, or to prevent glare outside the first glass body from entering the vehicle interior, thereby affecting comfort. Furthermore, the intermediate layer having a gradation also makes a privacy function possible.

The utility model discloses a when glass unit was applied to window glass, can adopt the dual mode to realize light extraction structure in the internal formation of second glass. The first method is to perform laser engraving before the hot bending process, that is, engraving microstructures on the inside of the flat (2D) glass, then putting the glass with the light extraction structures into a mold to be hot-bent into curved (3D) glass, and finally performing the lamination process of the glass assembly. The second way is to laser engrave after the hot bending process, i.e. directly inside the 3D glass, and then laminate the glass assembly. The two modes can be adjusted according to different application occasions and the material selection of the glass as required, as long as the laser engraving of the light extraction structure is realized under the condition that the strength and the performance of the glass are not damaged, or the strength or the performance of the engraved glass meets the national mandatory test standard.

In particular, in the first mode, the laser engraving process destroys the physical structure inside the glass, so that the inside of the glass is broken to generate white spots to form a microstructure or a pattern, and the hot bending process after engraving has certain requirements on the pattern. In other words, to avoid the glass from breaking during the hot bending process, it is advantageous to design the pattern not as a continuous line, or as a continuous large area pattern, so that the laser damage point to the inside of the glass is not concentrated in a certain area, thereby avoiding affecting the overall strength of the glass. On the other hand, the pattern is designed to be thin in line diameter and thin in glass breaking thickness, so that the pattern is not easy to be observed by a user after the light source is turned off, and a substantially transparent effect is achieved.

Fig. 3 to 5 each show different arrangements of the light sources in the glass component. Alternatively, the light source is for example a point-like or line-like light source integrated inside the glass body, or a light source attached to the edge of the glass body in a proximal, fitting or the like manner, such as a LED lighting strip, or a point-like LED with a light guide. Depending on the shape of the glass body, the light sources may be arranged at one or more side edges of the glass body, e.g. at one side edge of the glass body when the glass body is substantially triangular, and at opposite side edges of the glass body when the glass body is substantially quadrangular. A light source integrated inside the glass body is here understood to be integrated in the second glass body, the point of incidence of the light source being substantially in the same horizontal plane as the light extraction structure. In embodiments where the side edges of the glass assembly emit incident light, the light source may be formed as an encapsulation (e.g., in a hem) or mounted in other fixed fashion at the edges of the glass body. In the embodiment shown in fig. 3, the light source 150a may be disposed at the edges of the first and second glass bodies 110 and 120. In the embodiment shown in fig. 4, the first glass body 110 has a size larger than that of the second glass body 120, and in this case, the light source 150b may be disposed only at the edge of the second glass body 120. In the embodiment shown in fig. 5, the light source 150c is integrated in the second glass body 120 by being embedded in an opening 123 provided in the second glass body 120. The cross-section of the aperture 123 may be circular, rectangular, or other suitable shape. It should be understood that in the above embodiments, the light sources 150a, 150b, 150c may be one or more light sources, such as a strip-shaped light band arranged in a ring or a plurality of point-shaped light sources distributed at intervals, and the illustration is not limited thereto. In the above various embodiments, the light source may be a direct light source, or may further comprise a light guide configured to conduct incident light emitted by the light source at least towards the light extraction structures within the second glass body, adapted for total reflection of light rays at the non-light extraction structures and reflection, scattering or diffusion at the light extraction structures. It will be appreciated that the light guide may be selected to be any suitable optical device or micro-structured optical device, such as a light guiding strip, that achieves the above described adjustment of the direction of light.

The sealing member 160 is, for example, an aluminum foil, and in some cases, the sealing member 160 can be used as a reflector to reflect light incident thereon back into the second glass body 120 due to the mirror effect of the surface of the aluminum foil while achieving the sealing effect, so as to reduce the loss of illumination.

In one embodiment, the first glass body 110 is VG10 glass with a thickness of 2.1mm, the intermediate layer 130 is grey PVB with a thickness of 0.76mm, the second glass body 120 is plain white glass or ultra white glass without affecting the color of the light, the thickness can be selected from the range of 0.7-4.0 mm, the light extraction structures 140 are formed in the second glass body 120 by laser engraving, and the light sources 150c are embedded in the openings 123 of the second glass body 120 and isolated from the intermediate layer 130 by a sealing member 160, such as aluminum foil.
