Description

Technical Field

[0001] This utility model belongs to the field of lighting glass technology, and specifically relates to a light guiding system and a window assembly. Background Technology

[0002] The rapid development of industrial production has driven continuous innovation in vehicle design, and people's demand for improved appearance has become increasingly urgent. In this process, lighting glass, as a key medium for conveying information to the interior and / or exterior of vehicles, has become increasingly important. Vehicle manufacturers, by adding decorative patterns to lighting glass during the design process, have not only enhanced the vehicle's aesthetics but also strengthened brand recognition, thus gaining widespread attention and winning consumer favor.

[0003] However, existing technical solutions have certain limitations. Typically, decorative patterns on illuminated glass are visible under all lighting conditions, which obstructs part of the vehicle's field of vision, affecting the visual experience for both the driver and passengers. This fixed pattern display method cannot meet people's higher demands for visual appeal.

[0004] To overcome this problem, a new technological effect needs to be developed: decorative patterns are only visible when the illuminated glass is lit, and remain invisible when the glass is off. This effect not only enhances the vehicle's aesthetics and technological appeal but also maintains the clarity and integrity of the entire glass view when the lighting is not in use, providing a better visual experience for the driver and passengers. Utility Model Content

[0005] The purpose of this utility model is to provide a light guide system and window assembly that enables decorative patterns to be visible only when the illuminated glass is lit, and to be invisible when the glass is not lit.

[0006] To solve the above-mentioned technical problems, this utility model provides a light guiding system, comprising:

[0008] The first light guide strip is used to collect and converge the light from the light source and align it in the direction of light emission;

[0009] The second light guide strip, the first glass layer, and the second glass layer are stacked sequentially. One side of the second light guide strip is positioned opposite to the light-emitting surface of the first light guide strip. Light from the light source can pass through the first light guide strip and the second light guide strip and enter the first glass layer for total internal reflection.

[0010] A transparent ink layer, forming a decorative pattern, is applied to the first glass layer to disrupt the total internal reflection effect, allowing light to be reflected by the transparent ink layer and refracted through the first glass layer to display the pattern effect.

[0016] And / or, the second light guide strip is a glass plate;

[0017] And / or, the second glass layer is a glass plate;

[0018] And / or, the first adhesive layer and the second adhesive layer are PVB adhesive layers.

[0019] Optionally, in the above light guide system, the light-incident surface of the first light guide strip faces the light source, and the light-exit surface of the first light guide strip is non-contactly opposite to one side of the second light guide strip.

[0028] This utility model provides a window assembly, including the light guide system described above.

[0029] This utility model provides a light guiding system, the advantages of which are:

[0030] By setting a transparent ink layer on the first glass layer, the appearance of the transparent ink layer is designed as a decorative pattern. Light from the light source is converged and transmitted through a first light guide strip to a second light guide strip, and then refracted by the second light guide strip into the first glass layer. The transparent ink layer disrupts total internal reflection at the boundary of the first glass layer, causing the light to be reflected by the transparent ink layer and then refracted through the first glass layer, thus displaying the pattern effect. Furthermore, the shape of the transparent ink layer is not visible through the glass assembly when the light source is not illuminated. This configuration ensures that the decorative pattern is only visible when the light source of the light guide system is illuminated, and is invisible when the light is off.

[0031] This utility model also provides a window assembly with the above-mentioned light guide system, which has the same beneficial effects. Attached Figure Description

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] The core of this utility model is to provide a light guide system and window assembly that enables decorative patterns to be visible only when the light source is lit, and invisible when the light source is not lit.

[0044] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, the present invention provides a light guiding system including a light source 110, a first light guide strip 200, a second light guide strip 310, a first glass layer 320, a second glass layer 330, and a transparent ink layer 360.

[0046] In this embodiment, the light source 110 is an LED lamp. In other embodiments, the light source 110 may also be other light-emitting devices, which will not be described in detail here.

[0047] The first light guide strip 200 is used to collect the light from the light source 110, converge the divergent light from the light source 110, and collimate it in the light-emitting direction. The light from the light source 110 can enter through the light-incident surface of the first light guide strip 200, be continuously conducted and reflected inside, and then exit from the light-emitting surface into the second light guide strip 310.

[0048] The second light guide strip 310, the first glass layer 320, and the second glass layer 330 are stacked sequentially. One side of the second light guide strip 310 is positioned opposite the light-emitting surface of the first light guide strip 200, allowing light from the light source 110 to pass through the first light guide strip 200 and the second light guide strip 310 and enter the first glass layer 320 for total internal reflection.

[0049] A transparent ink layer 360 is disposed on the first glass layer 320 and can form a decorative pattern to disrupt the total internal reflection effect. When light undergoing total internal reflection within the first glass layer 320 shines on the transparent ink layer 360, it can be refracted through the decorative pattern on the first glass layer 320, thereby illuminating the decorative pattern, i.e., displaying the decorative pattern on the light-emitting surface of the first glass layer 300. The transparent ink layer effectively disrupts the total internal reflection effect.

[0050] It should be noted that the aforementioned "decorative patterns" include any one or combination of text, graphics, symbols, numbers, beacons, trademarks, etc., formed by dots, lines, and surfaces.

[0051] It should also be noted that the transparent ink layer 360 contains tiny particles or an uneven structure, which can cause light scattering. Scattering disperses light in multiple directions, thereby reducing the light intensity in specific directions and thus disrupting the conditions for total internal reflection.

[0052] This invention provides a light guiding system in which a transparent ink layer 360 is disposed on a first glass layer 320, and the transparent ink layer 360 is designed with a decorative pattern. Light from the light source 110 is collected and conducted through a first light guide strip 200 to a second light guide strip 310, and then refracted by the second light guide strip 310 into the first glass layer 320. The transparent ink layer 360 disrupts total internal reflection at the boundary of the first glass layer 320, causing the light to be reflected by the transparent ink layer 360 and then refracted through the first glass layer 320, thus displaying the pattern effect. Furthermore, the shape of the transparent ink layer is not visible through the glass assembly when the light source is not illuminated.

[0053] The above settings allow decorative patterns to be visible only when the light source of the light guide system is lit, and invisible when the light is off.

[0054] This application also includes: a first adhesive layer 340 connecting the second light guide strip 310 and the first glass layer 320, and / or a second adhesive layer 350 connecting the first glass layer 320 and the second glass layer 330.

[0055] The second light guide strip 310 is connected to the first glass layer 320 through the first adhesive layer 340, and the first glass layer 320 is connected to the second glass layer 330 through the second adhesive layer 350. Thus, the second light guide strip 310, the first adhesive layer 340, the first glass layer 320, the second adhesive layer 350, and the second glass layer 330 can be stacked in sequence to finally form a firmly connected glass assembly.

[0056] Furthermore, the first light guide strip 200 and the first glass layer 320 are fixedly connected by an optical adhesive layer, and the connection between the first light guide strip 200 and the first glass layer 320 is non-detachable. The refractive index of the optical adhesive layer needs to be consistent with the refractive index of the first glass layer 320 to prevent light refraction and ensure the performance of the optical product.

[0057] In a specific embodiment, the light-incident surface of the first light guide strip 200 faces the light source, and the light-exiting surface of the first light guide strip 200 is non-contactly opposite to one side of the second light guide strip 310.

[0058] Reference Figure 1 and Figure 5 The diagram shows the structural connection between the various components of the light guiding system.

[0059] The light-incident surface at one end of the first light guide strip 200 is concave to receive as much light as possible. The light-exit surface at the other end of the first light guide strip 200 is inclined relative to the light-incident surface of the first light guide strip 200, and the two ends of the first light guide strip 200 are at different height positions.

[0060] The second light guide strip 310 is a cuboid, with a simple structure, a large light-receiving surface, and is easier to manufacture and implement.

[0061] The structural design of the first light guide strip 200 and the second light guide strip 310 can be derived into more forms of light guide strip structure according to actual needs, and no further limitation is made here.

[0062] There is no connection between the light source 110 and the first light guide strip 200. The concave design of the first light guide strip 200 can gather more light from the light source.

[0063] This solution also includes a housing 400 covering the light source 110, the first light guide 200, and the second light guide 310. The housing 400 and the first glass layer 320 form an installation space to accommodate the light source 110, the first light guide 200, and the second light guide 310, preventing dust or moisture from entering. The first light guide 200 is fixed to the housing 400 or the circuit board 120 of the light source 110. The first light guide 200 is typically fixed using a fixing clip on the housing 400 or by direct connection to the circuit board 120. This fixing method is simple and effective, ensuring the stability of the first light guide 200 during use, and also facilitating later maintenance and replacement.

[0064] In a specific embodiment, the transparent ink layer 360 is fused to the first glass layer 320 using printing technology, forming a single unit. The ink can be printed on the glass surface to create a rich variety of patterns, text, and colors, giving the glass product a unique appearance. The fused transparent ink layer 360 forms a robust coating on the surface of the first glass layer 320, exhibiting excellent wear and scratch resistance.

[0065] In a specific embodiment, the first glass layer 320 is ultra-transparent glass. Most of the light collimated by the first light guide strip 200 undergoes total internal reflection in the ultra-transparent glass. Ultra-transparent glass is beneficial for increasing the propagation path of light. Its transmittance is higher than that of ordinary glass, its absorption coefficient is lower, and the light travels a longer distance within it.

[0066] The first light guide strip 200 is either PMMA (polymethyl methacrylate, also known as acrylic or plexiglass) or PC (polycarbonate) sheet. PMMA sheets have the advantages of high transparency and easy processing. PMMA sheets can also be replaced with PC sheets. The second light guide strip 310 and the second glass layer 330 can both be glass sheets, as long as they meet the characteristics of heat insulation, heat preservation, and noise reduction. The first adhesive layer 340 and the second adhesive layer 350 are PVB (polyvinyl butyral) adhesive layers. PVB adhesive layers have good adhesion to inorganic glass and can also absorb impact energy without producing shattered fragments.

[0067] To achieve more complex pattern effects, there are multiple transparent ink layers 360, which are discontinuously disposed on the first glass layer 320, especially at the junction of the first glass layer 320 and the second adhesive layer 350.

[0068] In particular, such as Figure 3 and Figure 4 As shown, a light source 110 and a first light guide strip 200 constitute a set of light incident units. A light guiding system includes multiple sets of light incident units, a second light guide strip 310, a first glass layer 320, and a second glass layer 330. The multiple sets of light incident units are arranged at intervals along the horizontal direction of the second light guide strip 310, which can provide a larger area of ​​illumination coverage.

[0069] In specific embodiments, both the first glass layer 320 and the second glass layer 330 are plate-like structures, or both are curved structures. The accompanying drawings in this case use flat glass as an example; the first glass layer 320 and the second glass layer 330 can also be curved glass, as long as it can ensure that light is transmitted along the required path.

[0070] Furthermore, this utility model also provides a window assembly, including the light guide system as described in the specific embodiments above. The window assembly can be applied to vehicles, and of course, it can also be applied to doors and windows, curtain walls, aircraft windows, or ship windows, etc.

[0071] Obviously, the window assembly containing the aforementioned light guide system has the same beneficial effects, which will not be elaborated here.
