DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1, refer to the attached Figure 2-6 , a vehicle window assembly, comprising a glass component 100 and an optical component 200; The glass assembly 100 includes, from the outside to the inside, an outer layer of glass 110, an intermediate layer 120, an inner layer of glass 130, and a light-inlet glass 140. The light-inlet glass 140 is bonded to the inner side 132 of the inner layer of glass 130 by optical glass adhesive 150. A reflective layer with a preset pattern is provided at a preset position between the intermediate layer 120 and the outer side 131 of the inner layer of glass 130. The optical assembly 200 includes a housing 210, a circuit board 220, and a plurality of light sources 230 and a light guide 240 fixed to the circuit board 220. The housing 210 and the inner glass 130 are fixedly connected by adhesive. The light guide 240 includes a light inlet surface 241, a reflective surface 242, and a light outlet surface 243. The light inlet surface 241 is adjacent to the light source 230, and the light outlet surface 243 is adjacent to the light-inlet side surface 141 of the light-inlet glass 140. The light emitted by the light source 230 includes an optical axis ray 231 propagating along its optical axis. After entering the light inlet surface 241 of the light guide 240, the optical axis ray 231 is totally reflected by the reflective surface 242 and then emitted from the light outlet surface 243. Among them, the light-incoming surface 241 is a focusing curved surface with a focusing effect; the optical component 200 is configured so that the optical axis light 231 entering the inner glass 130 is reflected by the outer surface 131 of the inner glass 130 for the first time and then emitted toward the inner surface 132 of the inner glass 130 to which the light-incoming glass 140 is not glued; the light propagating in the inner glass 130 is reflected by the reflective layer and then emitted into the vehicle, finally forming an ambient light effect with a preset pattern of light.

[0030] In order to better understand the working principle and technical effects of this embodiment, it is necessary to analyze the defects of the patent CN119459267A structure mentioned in the background technology before explaining the working principle and technical effects. Figure 1Why is the overall brightness of the skylight assembly low? This is because in the field of optics, LED light sources or illuminants actually propagate outward in the form of a light cone. The closer to the optical axis, the greater the energy of the light. The optical axis direction of the illuminant 42 in CN119459267A is basically parallel to the width direction (X axis) of the light guide bar 20. Without considering the absorption of light by the medium itself, the propagation of the light emitted by the illuminant 42 can be divided into three parts: the first part of the light is the light near the optical axis of the illuminant 42. This part of the light enters from the light-incoming side of the light guide bar 20 and the first adhesive member 70 and is directly emitted from the other side of the light guide bar 20 and the first adhesive member 70. This part of the light is close to the optical axis. Secondly, the long-distance propagation of light in the light guide strip 20 or the inner glass 13 depends on the total reflection characteristics of light. Among the light rays that enter the light guide strip 20 and the light incident side of the first adhesive member 70 obliquely near the non-optical axis of the light emitting body 42, the second part of the light rays is the light rays emitted from the other side of the light guide strip 20 and the first adhesive member 70 after one or more total reflections, and the third part of the light rays, that is, the remaining light rays, continue to propagate along the inner glass 13. In summary, the first and second parts of the light rays account for a higher proportion of the overall light rays, but they do not enter the inner glass 13 for propagation but are directly lost, resulting in a very low light utilization rate of the sunroof assembly.

[0031] Based on the above reasons, there are currently two common methods to improve light utilization:

[0032] First, the lower end surface of the light guide strip 20 is set as an inclined surface, that is, the lower end surface of the light guide strip 20 is no longer parallel to the optical axis direction of the light emitting body 42 but at a certain angle, so that the light that contacts the lower end surface of the light guide strip 20 is totally reflected and enters the inner layer of glass 13; although this method is feasible in principle, it is not suitable from the perspective of supply chain and process, because the area of ​​the skylight is very large and can only be manufactured by a specialized glass manufacturer, and the light guide strip 20 fixed to the skylight with glue is very long and requires assembly precision, so the gluing process of the light guide strip 20 also needs to be carried out by the glass manufacturer; generally speaking, the manufacturing process of glass determines The thickness of the glass should be stable and balanced. If the light guide strip 20 is designed to be an inclined surface, the tip of the light guide strip 20 will be fragile. Therefore, glass cannot be used as the material, and it can only be made of plastic such as PC and acrylic. However, glass manufacturers will not produce plastic light guide strips 20 simply because the light guide strip 20 needs to be made of plastic. Various injection molding equipment and related talents are involved, which will lead to a significant increase in equipment and labor costs. If the glass manufacturer purchases plastic light guide strips 20, it will also involve an overall increase in costs. Therefore, from the perspective of supply chain and process, the most suitable material for the light guide strip 20 is still glass.

[0033] Secondly, the angle at which the light from the light-emitting body 42 enters the light-incoming side of the light-guiding strip 20 and the first adhesive member 70 is adjusted. The main problem with this solution is that the circuit board carrying the light-emitting body 42 also needs to be tilted along with the light-emitting body 42. If the circuit board is tilted, the optical component as a whole will need to occupy more space in the Z-axis direction, which is unacceptable to the vehicle OEM from a design perspective.

[0034] The solution of this embodiment mainly adds a light guide 240 to transmit light so that the light emitted by the light source 230 can be inclined at a specific angle to the light-inlet glass 140. At the same time, the light-inlet surface 241 of the light guide 240 is a focusing curved surface with a focusing effect, so that the light emitted by the light source 230 is concentrated as much as possible on the optical axis; and most importantly, through optical design, the optical component 200 is configured so that the optical axis light 231 entering the inner layer of glass 130 is reflected by the outer surface 131 of the inner layer of glass 130 for the first time and then emitted to the inner surface 132 of the inner layer of glass 130 to which the light-inlet glass 140 is not adhered.

[0035] The principle of this embodiment is described in detail below:

[0036] The light emitted by light source 230 propagates outward in the form of a light cone. The propagation path of light in the entire window assembly is actually very complex, full of various reflections and refractions. However, as mentioned above, the light energy at the optical axis of light source 230 is the highest. Taking the optical axis light 231 as the research object, as long as the optical axis light 231 is ensured to have no loss or the loss is minimized, the overall light utilization rate of the window assembly can be guaranteed to a certain extent. Figure 4 As shown, light rays O1 to O8 are the main paths of light rays at the optical axis of light source 230, namely, optical axis light 231. In addition to the refracted light rays shown in the figure, optical axis light 231 also experiences reflected light rays (not shown) when passing through O5 and O6, i.e., when the medium changes. However, reflected light rays cannot be avoided through structural optimization, so it is not necessary to delve into them. Furthermore, in addition to the reflected light rays shown in the figure, optical axis light 231 also experiences refracted light rays (not shown) when passing through O7. Compared to reflected light rays, refracted light rays here are more easily propagated within the vehicle window assembly and less likely to escape, so it is not necessary to delve into them. In general, the main goal of this embodiment is to ensure that the reflected light, that is, the optical axis light 231 in the O7-O8 segment, is not lost. In other words, even if the optical axis light 231 is reflected for the first time by the outer side surface 131 of the inner layer of glass 130 in the inner layer of glass 130 and then emitted to the inner side surface 132 of the inner layer of glass 130 to which the light-inlet glass 140 is not adhered, it means that the optical axis light 231 will not be emitted from the light-inlet glass 140. The closer the light is to the optical axis light 231, the more light is retained, and the overall light utilization rate will be higher.

[0037] It should be noted that, in this embodiment, a simple detection is performed to determine whether the optical axis light 231 is reflected for the first time by the outer side surface 131 of the inner glass 130 in the inner glass 130 and then emitted to the inner side surface 132 of the inner glass 130 to which the light-inlet glass 140 is not glued. The original light source 230 can be replaced by a laser. The energy of the laser is very concentrated and can be simply equated with the optical axis light 231. A laser is set at the position of the original light source 230 and is made to enter the light guide 240 at an angle in the direction of the optical axis of the original light source 230. It is then possible to simply and intuitively determine whether the laser is ultimately emitted from the light-inlet glass 140 or the optical glass glue 150 layer.

[0038] In the vehicle window assembly, in order to achieve the result that "the optical axis light 231 is reflected by the outer side surface 131 of the inner glass 130 for the first time in the inner glass 130 and then emitted to the inner side surface 132 of the inner glass 130 to which the light-inlet glass 140 is not glued", the main influencing factors include the width of the light-inlet glass 140 and the light-inlet angle of the optical component 200. Among them, the function of the light-inlet glass 140 is to guide the light into the inner glass 130. Under the premise that the light-inlet glass 140 meets the optical performance and assembly process, the width of the light-inlet glass 140 has an optimal value. A value greater than the optimal value means an increase in the cost and weight of the light-inlet glass 140. A value less than the optimal value means that the optical performance may not be met or the process difficulty may be increased. Therefore, under normal circumstances, the width of the light-inlet glass 140 in the vehicle window assembly can be assumed to be the optimal value. As for the light incident angle of the optical component 200, in this embodiment, the optical component 200 is configured so that the optical axis light 231 emitted from the light exit surface 243 is obliquely directed toward the inner layer of glass 130 and enters the light incident side surface 141 of the light incident glass 140 at a first angle α relative to the light incident side surface 141 of the light incident glass 140, and the value of the first angle α is greater than or equal to 73 and less than or equal to 83 degrees.

[0039] Further investigation reveals that the factors affecting the light incident angle of the optical assembly 200 include the direction of the optical axis of the light source 230, the structure of the light emitting surface 243 of the light guide 240, and the structure of the reflective surface 242 of the light guide 240. These factors are discussed below:

[0040] Regarding the optical axis direction of the light source 230, in this embodiment, in order to make the overall thickness of the optical component 200 in the Z-axis direction smaller, the light source 230 is configured so that the optical axis direction of the light source 230 forms a second angle β with the light-incoming side surface 141 of the light-incoming glass 140, and the second angle is greater than or equal to 0 and less than or equal to 10 degrees.

[0041] Regarding the structure of the reflective surface 242 of the light guide 240, in this embodiment, the reflective surface 242 of the light guide 240 is a convex curved surface, and the reflective surface 242 is configured to converge the light passing through the reflective surface 242 with the optical axis light 231 as the center, wherein the acute angle formed between the tangent line of the reflective surface 242 on the cross section of the light guide 240 and the optical axis of the light source 230 gradually increases along the optical axis direction of the light source 230. Figure 6 As shown, light from light source 230 is emitted toward reflective surface 242 in the form of a light cone. Assuming reflective surface 242 is a flat surface, the angle between the reflected dotted light and the optical axis light 231 of the O2-O3 segment is relatively large. It can be imagined that after the light from light source 230 enters the light intake glass 140, more light will escape from the light intake glass 140. However, if reflective surface 242 is a convex surface, the angle between the reflected solid light and the optical axis light 231 of the O2-O3 segment is relatively small. It can be imagined that after the light from light source 230 enters the light intake glass 140, more light will propagate through the inner layer of glass 130.

[0042] Regarding the structure of the light-emitting surface 243 of the light guide 240, in this embodiment, a preferred solution is that the light-emitting surface 243 of the light guide 240 is a plane obliquely toward the direction of the inner layer of glass 130, and the light-emitting surface 243 is set at a third angle γ with the light-incoming side surface 141 of the light-incoming glass 140, and the third angle γ is 20°±10°; in this solution, the light-emitting surface 243 of the light guide 240 simply adjusts the angle of the light emitted from the light-emitting surface 243.

[0043] In another preferred embodiment, the light-emitting surface 243 of the light guide 240 is an outwardly convex curved surface that is obliquely oriented toward the inner glass. The light-emitting surface 243 is configured to converge light passing through the light-emitting surface 243 with the optical axis ray 231 as the center, and the focal point of the light-emitting surface 243 is not located on the path of the optical axis ray 231. The principle of this embodiment is similar to that of the convexly curved reflective surface 242, and its function is also to converge light, maximizing the amount of light that enters the light-inlet glass 140 and propagates through the inner glass 130.

[0044] In this embodiment, the divergence angle of the light source 230 is preferably 120 degrees. At the same time, in order to ensure that the light guide 240 can receive the light emitted by the light source 230 as much as possible, the light guide 240 also includes a first section 245 and a second section 246 located on both sides of the light input surface 241 and smoothly transitioning. The angle between the first section 245 and the second section 246 is greater than or equal to the divergence angle of the light source 230.

[0045] Considering that the relative position between the light guide 240 and the light source 230 cannot change, otherwise it will affect the light incident angle of the optical component 200, in this embodiment, the light guide 240 also includes a fixing portion 247, which extends outward from the surface of the first section 245 or the second section 246 and is fixed on the circuit board 220. Since the fixing portion 247 extends outward from the surface of the first section 245 or the second section 246, the light emitted by the light source 230 basically will not directly hit the fixing portion 247.

[0046] Example 2, an optical component, used in a vehicle window assembly, the vehicle window assembly including light-inlet glass, the optical component including a circuit board, a light source fixed to the circuit board, and a light guide member, the light guide member including a light-inlet surface, a reflective surface, and a light-outlet surface, the light-inlet surface being proximate to the light source, and the light-outlet surface being proximate to the light-inlet side of the light-inlet glass; light emitted by the light source including optical axis light propagating along its optical axis, the optical axis light entering the light-inlet surface of the light guide member, being totally reflected by the reflective surface, and then exiting the light-outlet surface; Among them, the light-incoming surface is a focusing curved surface with a focusing effect; the optical component is configured so that the optical axis light emitted from the light-outgoing surface is obliquely toward the vehicle window assembly and enters the light-incoming side of the light-incoming glass at a first angle α relative to the light-incoming side of the light-incoming glass, and the first angle α is greater than or equal to 73 and less than or equal to 83 degrees.

[0047] The light source is configured so that the optical axis direction of the light source forms a second angle β with the light-entering side surface of the light-entering glass, and the second angle β is greater than or equal to 0 and less than or equal to 10 degrees; the light-emitting surface of the light guide is a plane obliquely toward the inner layer of glass and the light-emitting surface is set at a third angle γ with the light-entering side surface of the light-entering glass, and the third angle γ is 20°±10°.

[0048] The reflective surface of the light guide is an outward convex surface, and the reflective surface is configured to converge the light passing through the reflective surface with the optical axis light as the center; the acute angle formed between the tangent of the reflective surface on the cross section of the light guide and the optical axis of the light source gradually increases along the optical axis direction of the light source.

[0049] This embodiment protects an optical component, the structure of which is substantially the same as that of the optical component in Example 1. Therefore, the working principle and technical effects of this embodiment may refer to Example 1.

[0050] Although the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that it is not limited to the above embodiments and that various changes in form and details may be made within the scope of the claims.
