Abstract
Description
Technical Field
[0001] This utility model belongs to the field of light guide system technology, and specifically relates to a light guide 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:
[0007] light source;
[0008] A light guide plate is used to collect and converge the light from the light source and collimate it in the direction of light emission.
[0009] A first glass layer, an adhesive layer, and a second glass layer, wherein the first glass layer is connected to the second glass layer through the adhesive layer, and the first glass layer is connected to the light-emitting surface of the light guide plate, and light can undergo total internal reflection within the first glass layer;
[0010] A transparent ink layer, forming a decorative pattern, is applied to the adhesive 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.
[0011] Optionally, in the above light guide system, one end of the light guide plate faces the light source, and the other end is connected to the lower surface of the first glass layer.
[0012] Optionally, in the above light guide system, one end of the light guide plate is a hemispherical surface;
[0013] And / or, the other end of the light guide plate is a polyhedron, one face of which is attached to the lower surface of the first glass layer.
[0014] Optionally, in the above light guide system, the light guide plate is fixedly connected to the first glass layer by an optical adhesive layer.
[0015] Optionally, in the above light guiding system, the refractive index of the optical adhesive layer is the same as that of the first glass layer.
[0016] Optionally, in the above light guiding system, the transparent ink layer is fused together with the first glass layer.
[0017] Optionally, in the above light guiding system, the first glass layer is ultra-transparent glass;
[0018] And / or, the light guide plate is a PMMA plate or a glass plate;
[0019] And / or, the adhesive layer is a PVB adhesive layer.
[0020] Optionally, in the above light guiding system, there are multiple transparent ink layers, and the multiple transparent ink layers are discontinuously disposed at the junction of the adhesive layer and the first glass layer.
[0021] Optionally, in the above light guiding system, both the first glass layer and the second glass layer are plate-shaped structures or curved structures.
[0022] This utility model provides a window assembly, including the light guide system described above.
[0023] This utility model provides a light guiding system, the advantages of which are:
[0024] 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 a light source is gathered and conducted into the first glass layer through a light guide plate. 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, 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. Thus, the decorative pattern is only visible through the first glass layer when the light source of the light guide system is illuminated, and is invisible when the light is off.
[0025] This utility model also provides a window assembly with the above-mentioned light guide system, which has the same beneficial effects. Attached Figure Description

[0040] 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.
[0041] 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.
[0042] 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.
[0043] Specifically, the light guiding system provided by this utility model includes a light source 100, a light guide plate 200, a first glass layer 300, an adhesive layer 400, a second glass layer 500, and a transparent ink layer 600.
[0044] In this embodiment, the light source 100 is an LED lamp. In other embodiments, the light source 100 may also be other light-emitting devices, which will not be described in detail here.
[0045] The light guide plate 200 is used to collect the light from the light source 100, converge the divergent light from the light source 100, and collimate it in the light-emitting direction. The light from the light source 100 can enter through the light-incident surface of the light guide plate 200, be continuously conducted and reflected inside, and then exit from the light-emitting surface into the first glass layer 300.
[0046] The first glass layer 300 is connected to the second glass layer 500 via an adhesive layer 400, achieving a stacked arrangement to form a glass assembly. The first glass layer 300 is connected to the light-emitting surface of the light guide plate 200. A portion of the light, especially the collimated light from the light guide plate 200, can undergo total internal reflection within the first glass layer 300.
[0047] A transparent ink layer 600 is disposed at the boundary of the first glass layer 300. When light undergoes total internal reflection within the first glass layer 300 and shines onto the transparent ink layer 600, it is refracted through the decorative pattern disposed on the first glass layer 300, thereby illuminating the decorative pattern and displaying it on the light-emitting surface of the first glass layer 300. The transparent ink layer 600 thus achieves the effect of disrupting total internal reflection.
[0048] 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.
[0049] It should also be noted that the transparent ink layer 600 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.
[0050] This invention provides a light guiding system in which a transparent ink layer 600 is disposed on a first glass layer 300, and the transparent ink layer 600 is designed with a decorative pattern. Light from the light source 100 is collected and conducted into the first glass layer 300 by a light guide plate 200. The transparent ink layer 600 disrupts total internal reflection at the boundary of the first glass layer 300, causing the light to be reflected by the transparent ink layer 600 and then refracted through the first glass layer 300, displaying the pattern effect. Furthermore, the shape of the transparent ink layer 600 is not visible through the glass assembly when the light source 100 is not lit.
[0051] The above settings allow the decorative pattern to be visible only when the light source 100 of the light guide system is lit, and to be invisible when it is not lit.
[0052] In a specific embodiment, one end of the light guide plate 200 faces the light source 100, and the other end is connected to the lower surface of the first glass layer 300.
[0053] Reference Figures 1-3 A schematic diagram of the structure is shown, showing three light sources 100 and light guide plates 200 arranged at different angles.
[0054] exist Figure 1 In the structure shown, one end of the light guide plate 200 is a hemispherical surface. The other end of the light guide plate 200 is a polyhedron with a triangular cross-section, and one face of the polyhedron is in contact with the lower surface of the first glass layer 300. The center line of the light source 100 and the hemispherical surface of the light guide plate 200 is arranged at an angle (the angle between the center line and the lower surface of the first glass layer 300 is an acute angle).
[0055] exist Figure 2 and Figure 5 In the structure shown, one end of the light guide plate 200 is a hemispherical surface. The other end of the light guide plate 200 is a polyhedron with a triangular cross-section, and one face of the polyhedron is in contact with the lower surface of the first glass layer 300. The center line of the light source 100 and the hemispherical surface of the light guide plate 200 is arranged horizontally (this center line is parallel to the lower surface of the first glass layer 300).
[0056] exist Figure 3 and Figure 6In the structure shown, one end of the light guide plate 200 is a hemispherical surface. The other end of the light guide plate 200 is composed of two polyhedra, with rectangular and parallelogram cross-sections, respectively. One face of each polyhedron is in contact with the lower surface of the first glass layer 300. The light source 100 is arranged perpendicularly to the center line of the hemispherical surface of the light guide plate 200 (this center line is perpendicular to the lower surface of the first glass layer 300). Of course, the other end of the light guide plate 200 can also be composed of three or more polyhedra connected sequentially. By using multiple polyhedra in combination, or by arranging the light source 100 and the light guide plate 200 at different angles, various arrangement methods for the light source 100 and the light guide plate 200 can be achieved, making full use of space design.
[0057] The three different structural designs described above can collimate light in a specific direction, thereby improving efficiency. Of course, based on the above principles, many more forms of light guide plate structures can be designed, which will not be further limited here.
[0058] There is no connection between the light source 100 and the light guide plate 200. The hemispherical design of the light guide plate 200 can gather more light from the light source 100.
[0059] Furthermore, the light guide plate 200 and the first glass layer 300 are fixedly connected by optical adhesive, and the connection between the light guide plate 200 and the first glass layer 300 is non-detachable. The refractive index of the optical adhesive needs to be consistent with the refractive index of the first glass layer 300 to prevent light refraction and ensure the performance of the optical product.
[0060] In a specific embodiment, the transparent ink layer 600 is fused to the first glass layer 300 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 600 forms a robust coating on the surface of the first glass layer 300, exhibiting excellent wear and scratch resistance.
[0061] In a specific embodiment, the first glass layer 300 is ultra-transparent glass. Most of the light collimated by the light guide plate 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.
[0062] The light guide plate 200 is made of PMMA (polymethyl methacrylate, also known as acrylic or plexiglass) or glass. PMMA has the advantages of high transparency and easy processing. PMMA can also be replaced with glass. The adhesive layer 400 is a PVB (polyvinyl butyral) adhesive layer. PVB adhesive layer has good adhesion to inorganic glass and can also absorb impact energy without producing shattered fragments. The second glass layer 500 can be ordinary glass, which only needs to meet the characteristics of heat insulation, heat preservation, and noise reduction.
[0063] To achieve more complex pattern effects, such as Figure 4 As shown, there are multiple transparent ink layers 600, which are discontinuously disposed at the junction of the adhesive layer 400 and the first glass layer 300.
[0064] In specific embodiments, both the first glass layer 300 and the second glass layer 500 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 300 and the second glass layer 500 can also be curved glass, as long as it can ensure that light is transmitted along the required path.
[0065] 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.
[0066] Obviously, the window assembly containing the aforementioned light guide system has the same beneficial effects, which will not be elaborated here.
