Description

Technical Field

[0001] This invention relates to the field of automotive interior lighting technology, and more specifically, to a concealed ambient lighting device embedded in a vehicle window glass sealing system. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demand from consumers for personalized and comfortable car interiors, ambient lighting has gradually become an important feature for enhancing vehicle quality and driving experience. Currently, ambient lighting is mainly installed on the dashboard, center console, and door panels. While these installation methods achieve certain lighting effects and decorative appeal, their prominent placement often lacks design subtlety and visual mystery, failing to meet the needs of users who demand higher levels of aesthetics and immersion.

[0003] Some high-end models attempt to integrate ambient lighting into concealed areas such as window frames and door gaps to enhance the concealment of lighting and the sense of immersion in the space. However, such solutions generally face the following problems: First, the embedded structure has a complex installation process, relying on precision molds or custom components, which leads to a significant increase in manufacturing and assembly costs. Second, the placement of ambient lighting components can easily interfere with the sealing of the original door or window structure, resulting in air leakage, water leakage, or noise problems, making it difficult to balance decorative function and sealing performance. Finally, due to the complex structural design and limited space occupation, later repairs or replacements are difficult, affecting user convenience.

[0004] To address this issue, a concealed ambient lighting device embedded in the vehicle window glass sealing system is proposed. Summary of the Invention

[0005] The present invention aims to provide a concealed ambient light device embedded in the vehicle window glass sealing system, so as to solve or improve the problems of poor concealment, complicated installation, high maintenance cost and easy impact on the sealing performance of the vehicle window in the existing vehicle interior ambient light.

[0006] In view of this, a first aspect of the present invention is to provide a concealed ambient light device embedded in a vehicle window glass sealing system.

[0007] A second aspect of the present invention is to provide an illumination method.

[0008] A first aspect of the present invention provides a concealed ambient light device embedded in a vehicle window glass sealing system. The vehicle window glass sealing system includes an outer window deflector and an inner window deflector respectively disposed on both sides of the vehicle window glass. The concealed ambient light device includes: a first light-emitting part disposed in a first groove of the outer window deflector; a first port communicating with the first groove is formed on the side of the outer window deflector near the vehicle window glass, and light generated by the first light-emitting part is transmitted to the outer edge of the vehicle window glass through the first port; a second light-emitting part disposed in a second groove of the inner window deflector; a second port communicating with the second groove is formed on the side of the inner window deflector near the vehicle window glass, and a light guide component extending outward through the second port is disposed on the second light-emitting part, and light generated by the second light-emitting part is transmitted to the inner edge of the vehicle window glass through the light guide component.

[0009] In any of the above technical solutions, the first light-emitting part includes an outer window ambient light, and the second light-emitting part includes an inner window ambient light; the outer window ambient light and the inner window ambient light extend along the circumferential edge of the window glass, respectively.

[0010] In any of the above technical solutions, the ambient light on the outer side of the vehicle window includes: a first light source extending into the first groove; a first lampshade circumferentially wrapping around the outside of the first light source; and the outer wall of the first lampshade abutting against the inner wall of the first groove.

[0011] In any of the above technical solutions, the outer water deflector of the car window is fixed on the outer sheet metal of the car door, and the first groove is located horizontally between the outer sheet metal of the car door and the car window glass.

[0012] In any of the above technical solutions, the ambient light inside the vehicle window includes: a second light source extending into the second groove; a second lampshade circumferentially wrapping around the outside of the second light source; and the outer wall of the second lampshade abutting against the inside of the second groove.

[0013] In any of the above technical solutions, the inner water deflector strip of the car window is fixed on the inner panel sheet metal of the car door, and the second groove is located laterally between the inner panel sheet metal of the car door and the car window glass.

[0014] In any of the above technical solutions, the light guide assembly includes a light guide strip connected to the second lampshade; the inner water deflector strip of the car window is located longitudinally between the inner sheet metal of the car door and the inner protective panel of the car door, and the end of the light guide strip away from the second lampshade is located laterally between the car window glass and the inner protective panel of the car door.

[0015] In any of the above technical solutions, light is transmitted to the irradiation area of ​​the vehicle window glass via the first port, and the lateral light is transmitted to the irradiation area of ​​the vehicle window glass via the end of the light guide strip.

[0016] In any of the above technical solutions, the light guide assembly further includes: a velvet strip disposed on the side of the light guide strip facing the vehicle window glass.

[0017] A second aspect of the present invention provides a lighting method comprising the following steps: turning on the vehicle power supply and supplying power to the first light-emitting part and the second light-emitting part; the first light-emitting part projecting light from outside the vehicle to the side wall edge of the window glass through the first port; the second light-emitting part projecting light from inside the vehicle to the side wall edge of the window glass through the light guide assembly; and the window glass illuminating the interior of the vehicle through the light received simultaneously by the inner and outer side walls.

[0018] The beneficial effects of this invention compared to the prior art are as follows: The ambient lighting components are cleverly embedded into the outer and inner water deflectors of the window glass sealing system, achieving a high degree of integration between the lighting fixtures and the sealing structure. This avoids the situation where traditional ambient lighting is exposed and damages the interior of the doors or the appearance of the windows, making the entire vehicle lighting system more concise and unified in appearance, and improving the integrity and concealment of the overall design.

[0019] By projecting light onto the outer and inner edges of the window glass through the first and second light-emitting parts respectively, the front and rear light paths correspond in the direction of glass thickness, so that the glass edge forms a visually encircling light band, creating a lighting experience with coordinated front and rear lighting effects and a sense of depth and layering. This not only enhances the nighttime visibility of the vehicle exterior, but also improves the visual comfort and atmosphere of the cabin interior.

[0020] The ambient lighting components are installed in the pre-set grooves of the water deflector. They can be quickly positioned and firmly fixed by means of snap-fit, adhesive or embedding, without the need to make holes in the door sheet metal or glass, thus avoiding damage to the original vehicle structure. At the same time, since the light body is placed in a detachable part, it is convenient for later replacement or maintenance, which significantly reduces maintenance costs and complexity.

[0021] Considering the sealing function of the water deflector, by arranging grooves and setting ports or light guide structures, light can be smoothly led out without damaging the sealed closure path, ensuring that the vehicle's performance in terms of waterproofing, dustproofing, and sound insulation is not compromised in any way.

[0022] The ambient lighting inside the windows, through the combination of light guide strips and velour strips, can achieve secondary softening and uniform scattering of light, effectively avoiding glare caused by passengers looking directly at the light source, improving lighting comfort, and is especially suitable for creating a quiet and warm cabin atmosphere, meeting the needs of improving user experience.

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0028] Please see Figures 1-3 The following describes a concealed ambient light device embedded in a vehicle window glass sealing system according to some embodiments of the present invention.

[0029] An embodiment of the first aspect of the present invention provides a concealed ambient lighting device embedded in a vehicle window glass sealing system. In some embodiments of the present invention, such as... Figures 1-2 As shown, the concealed ambient lighting device's window glass sealing system includes an outer window deflector 3 and an inner window deflector 4 respectively disposed on both sides of the window glass 5. The concealed ambient lighting device includes: The first light-emitting part is disposed in the first groove of the outer water deflector strip 3 of the vehicle window; the outer water deflector strip 3 of the vehicle window has a first port connected to the first groove on the side near the window glass 5, and the light generated by the first light-emitting part is transmitted to the outer edge of the window glass 5 through the first port.

[0030] The second light-emitting part is disposed in the second groove of the inner water-retaining strip 4 of the window; a second port is formed on the side of the inner water-retaining strip 4 near the window glass 5, which communicates with the second groove; a light guide component is disposed on the second light-emitting part that extends outward through the second port; the light generated by the second light-emitting part is transmitted to the inner edge of the window glass 5 through the light guide component.

[0031] This invention provides a concealed ambient lighting device embedded in a vehicle window sealing system. By cleverly embedding the ambient lighting components into the structure of the window sealing system, it achieves the goal of enhancing the interior lighting atmosphere and design quality without affecting the overall sealing performance and visual cleanliness of the vehicle. Specifically, the window sealing system upon which this device relies includes an outer water-repellent strip 3 and an inner water-repellent strip 4 located on both sides of the window glass 5. These two strips are respectively attached to the outer and inner edges of the window glass 5, serving as an important component of the overall vehicle sealing system and providing multiple functions such as waterproofing, dustproofing, noise reduction, and glass guiding.

[0032] The exterior windshield strip 3 is made of a flexible or elastic rubber-like material. It features an integrally formed first groove on the side near the window glass 5. This groove, in cross-section, has a cavity structure adapted to the shape of the ambient lighting components to accommodate the first light-emitting part. The first light-emitting part is securely installed in this first groove via snap-fit, insertion, or adhesive, preventing loosening or detachment due to vibration or temperature changes during vehicle operation. Furthermore, the exterior windshield strip 3 also has a first port near the edge of the window glass 5. This first port communicates with the first groove, allowing the light generated by the first light-emitting part to be transmitted to the outer edge of the window glass 5 at a controlled angle and direction. Because this first port directly faces the thickness direction of the window glass 5, light can accurately illuminate the glass edge area without damaging the door's appearance or the original sealing structure. This creates a highly recognizable, uniform, and soft contour light effect on the outer side of the vehicle, enhancing visual recognition and improving the overall sophistication and recognizability of the vehicle's lighting design.

[0033] By concealing the first light-emitting part inside the outer water deflector 3 of the car window and accurately projecting light onto the outer edge of the car window glass 5 through the first port, the ambient lighting function and the sealing strip structure are highly integrated. This not only saves the installation space required by traditional lamps and avoids the risk of damaging the door structure or exposing electrical components, but also effectively improves the lateral visibility of the vehicle and the aesthetics of the vehicle body outline when driving at night. This fully demonstrates the synergistic optimization advantages of this invention in terms of aesthetics, functionality and engineering feasibility.

[0034] The second light-emitting part is disposed in the inner window baffle 4 on the inner side of the window glass 5, specifically embedded in the second groove formed by the inner window baffle 4. As a component of the window glass 5 sealing system, the inner window baffle 4 needs to meet the requirements of effective sealing and coverage of the inner side of the window glass 5, while also possessing a certain degree of flexibility and elasticity to adapt to the movement trajectory of the glass during lifting and lowering, and to ensure a smooth transition with the interior structure. Furthermore, the inner window baffle 4 has a second port on the side near the window glass 5, which communicates with the second groove to form a structural opening facing the window glass 5, used to guide the light from the second groove outwards.

[0035] The second light-emitting part is installed in the aforementioned second groove, and its structural layout is similar to that of the first light-emitting part, enabling stable embedding and fixation through the groove. To effectively guide the light, a light guide component is connected to the second light-emitting part. This light guide component extends outward from the second light-emitting part, passes through the opening structure of the second port, and extends towards the inner edge of the window glass 5, allowing the light emitted by the second light-emitting part to be conducted along the light guide path to the inner side of the window glass 5. In this process, the light guide component not only guides the light but also constrains and evenly distributes the light's propagation path, thereby ensuring the continuity of the lighting effect and the softness of the vision.

[0036] Through the above structural arrangement, the second light-emitting unit and the inner window baffle 4 form a functional integration relationship. This means that while maintaining the original sealing function, the light-emitting component is embedded and installed. Furthermore, the light is projected onto the inner edge of the glass by a light guide component corresponding to the window glass 5, thus presenting a highly concealed, uniform, and soft edge lighting effect inside the vehicle. This not only simplifies the independent installation of the lamps and interior panels structurally, but also enhances the visual hierarchy and lighting atmosphere of the interior space, while avoiding the risk of damaging the original vehicle's sealing structure, thus ensuring assembly consistency and reliability.

[0037] In summary, by setting a first light-emitting part inside the outer water deflector 3 and a second light-emitting part inside the inner water deflector 4, and by using a first port and a light guide assembly to transmit light to the outer and inner edges of the window glass 5 respectively, the ambient lighting function is highly integrated with the sealing system of the window glass 5. Structurally, the concealed lighting arrangement can be achieved without additional openings or modifications to the door sheet metal. This maintains the integrity and simplicity of the vehicle's side profile in terms of overall appearance, creates a uniform, soft, and enveloping edge light strip in terms of internal visual effect, and does not compromise the sealing performance of the vehicle. The exterior water deflector 3 and the interior water deflector 4 effectively block rainwater, dust, and noise. Simultaneously, leveraging the flexible structure and repositioning elasticity of the water deflector itself, the light-emitting components can be quickly snapped or inserted for installation. They can also be easily disassembled for later maintenance or replacement, significantly reducing assembly and maintenance costs. Furthermore, the use of low-power, long-life LED light sources reduces energy consumption and maintenance frequency. Overall, it balances aesthetics, concealment, sealing, economy, and user experience, providing an efficient, reliable, and easily mass-producible solution for improving in-vehicle lighting and overall vehicle quality.

[0038] In any of the above embodiments, the first light-emitting part includes an outer window ambient light 1, and the second light-emitting part includes an inner window ambient light 2.

[0039] The ambient light 1 on the outside of the window and the ambient light 2 on the inside of the window extend along the circumferential edge of the window glass 5.

[0040] In this embodiment, after the vehicle power is turned on and supplies power to the first and second light-emitting parts, the ambient light 1 on the outer side of the window emits light continuously along the outer periphery of the window glass 5. The light is evenly injected into the thickness direction of the glass through the first port of the outer water deflector 3, outlining a continuous light band on the outer side of the glass, so that the side of the vehicle body presents a striking edge lighting effect at night or in a dark environment. At the same time, the ambient light 2 on the inner side of the window emits light synchronously along the inner periphery of the window glass 5. Its light is guided by the light guide component and scattered through the velvet strip 21, forming a soft and uniform ring light curtain on the inner side of the glass, providing the occupants with a strong sense of immersion and low glare indoor ambient lighting.

[0041] Two light strips correspond to each other in the direction of glass thickness, forming a complete halo together, which not only enhances the appearance recognition but also improves the cabin comfort. The entire operation does not damage the original sealing and guiding functions of the water deflector, and the light-emitting part is located in the groove, which can be quickly snapped on, disassembled and maintained, taking into account the lighting effect, concealment and convenience of later maintenance.

[0042] In any of the above embodiments, the ambient light 1 on the outer side of the vehicle window includes: The first light source 11 extends and is disposed in the first groove.

[0043] The first lampshade 12 circumferentially wraps around the outside of the first light source 11; the outer wall of the first lampshade 12 abuts against the inner wall of the first groove.

[0044] In this embodiment, when the vehicle power supply supplies power to the first light source 11, the first light source 11 continuously emits light along the length of the first groove. The resulting linear beam of light is first circumferentially covered by the first lampshade 12 inside the groove. Since the outer wall of the first lampshade 12 is always in close contact with the inner wall of the first groove, the first lampshade 12 forms a stable and fixed interface during operation, suppressing the influence of vehicle vibration on the position of the light source and avoiding light spot jumping or uneven brightness. On the other hand, it forms a closed light guide cavity, so that the light is uniformly output along the groove direction after being refracted / scattered inside the first lampshade 12, and is directionally projected towards the outer edge of the window glass 5 through the previously set first port. Thus, while maintaining concealed installation and original sealing integrity, the outer ambient light can form a continuous, soft and stable light band effect on the outer edge of the glass, which not only enhances the nighttime visibility of the vehicle side but also ensures the long-term reliability of the light body and the waterproof and dustproof performance of the installation part.

[0045] Furthermore, a first extending edge is formed on the side wall of the outer water deflector strip 3 of the vehicle window, and the first extending edge extends from the first port into the interior of the first groove; the inner diameter of the first port along the glass thickness direction is smaller than the diameter of the first lampshade 12.

[0046] In any of the above embodiments, the outer water deflector strip 3 of the car window is fixed on the outer sheet metal panel 7 of the car door, and the first groove is located horizontally between the outer sheet metal panel 7 of the car door and the car window glass 5.

[0047] In this embodiment, the outer water deflector 3 of the window is firmly fixed to the outer side of the outer panel 7 of the door by means of clips or adhesive. Its elastic base and the folded edge of the sheet metal form a continuous fitting interface, thereby achieving the first waterproof seal on the exterior of the vehicle body. The first groove integrally formed along the length direction inside the outer water deflector 3 of the window is located in the interlayer position between the outer panel 7 of the door and the window glass 5. The narrow gap space naturally formed by this interlayer avoids occupying the glass lifting channel and allows the two sides of the groove to be clamped by the sheet metal and the glass, which enhances the structural stability and vibration resistance. When the first light source 11 and its covering lamp cover are embedded in the first groove, the outer wall of the water deflector prevents rainwater from directly washing over it, the back of the outer panel 7 of the door provides rigid support, and the inner side of the window glass 5 serves as the light projection interface. The three work together to achieve concealed installation, sealed protection and directional light output of the lamp body, ensuring that the ambient light remains reliably fixed, well sealed and uniform in light effect during vehicle operation.

[0048] In any of the above embodiments, the ambient light 2 inside the vehicle window includes: The second light source 24 extends and is disposed in the second groove.

[0049] The second lampshade 23 circumferentially wraps around the outside of the second light source 24; the outer wall of the second lampshade 23 abuts against the inside of the second groove.

[0050] In this embodiment, the ambient light 2 inside the vehicle window includes a second light source 24 disposed in the second groove of the inner window baffle 4 and a second lampshade 23 covering the outside of it. The second light source 24 extends along the length of the second groove, forming a continuous and uniform linear light source layout to meet the needs of overall illumination of the inner periphery of the window glass 5. The second lampshade 23 is made of flexible or semi-rigid light-transmitting material and has a strip-shaped structure. Its overall shape matches the cavity contour of the second groove. During installation, it covers the second light source 24 circumferentially and tightly abuts against the inner wall of the second groove through its outer wall, thereby limiting, fixing, and protecting the second light source 24. In operation, the light generated by the second light source 24 is uniformly shaped and guided inside the second lampshade 23, which can prevent local over-brightness and glare, and improve the directional control capability of light output. At the same time, the second lampshade 23, as a physical isolation layer between the second groove and the interior space of the vehicle, can effectively block dust and moisture from entering the light-emitting area, improving the stability and reliability of the ambient light operation. Through the above-mentioned structural coordination, the second light source 24 emits light stably under the cover of the second lampshade 23 and the guidance of the second groove, creating a clear and consistent light-incident interface for the light guide component to subsequently draw out light, thereby ensuring the softness, consistency and design coherence of the lighting effect inside the window glass 5.

[0051] Furthermore, a second extended edge is formed on the side wall of the inner water deflector strip 4 of the window, and the second extended edge extends from the second port into the interior of the second groove; the height of the second lamp cover 23 in the longitudinal direction is lower than that of the first lamp cover 12.

[0052] In any of the above embodiments, the inner window baffle 4 is fixed on the inner door panel sheet metal 8, and the second groove is located horizontally between the inner door panel sheet metal 8 and the window glass 5.

[0053] In this embodiment, the inner window deflector 4 is securely fixed to the folded edge of the inner door panel sheet metal 8 using clips, grips, or special adhesive strips. Its elastic substrate forms a first contact surface with the inner door panel sheet metal 8, providing reliable waterproof, dustproof, and noise-reducing sealing under vehicle vibration conditions. The second groove, integrally formed along the length of the deflector, is laterally located in the interlayer area between the inner door panel sheet metal 8 and the window glass 5: its outer wall is rigidly supported by the sheet metal, and its inner wall is close to the window glass 5, providing a directional interface for light emission; this arrangement neither interferes with the glass lifting trajectory nor occupies the interior space of the door. After the second light source 24 and the second lamp cover 23 are embedded in the second groove, the outer wall of the lamp cover and the inner wall of the groove abut against each other to achieve limiting and protection. At the same time, the groove is clamped by sheet metal and glass in both directions, forming a stable rigid-flexible sandwich structure. This allows the ambient light to remain fixed, sealed and emit light evenly under vibration, temperature difference and long-term use conditions. This ensures that the light guide component accurately and softly projects light onto the inner edge of the window glass 5, creating a consistent and comfortable ambient light strip inside the vehicle.

[0054] In any of the above embodiments, the light guide assembly includes a light guide strip 22 connected to the second lampshade 23.

[0055] The inner water deflector 4 is located longitudinally between the inner door panel 8 and the inner door guard plate 6, and the end of the light guide strip 22 away from the second lamp cover 23 is located laterally between the window glass 5 and the inner door guard plate 6.

[0056] In this embodiment, the light guide assembly is composed of a light guide strip 22 integrally connected to the second lamp cover 23. The light guide strip 22 extends along the longitudinal direction of the inner window baffle 4 and forms a continuous light path interface with the second lamp cover 23 in structure, so that the light emitted by the second light source 24 can be smoothly coupled into the light guide strip 22 after being uniformly shaped inside the lamp cover. The inner window baffle 4 itself is longitudinally installed between the inner door panel sheet metal 8 and the inner door guard plate 6, and forms a clamp with the inner guard plate by relying on the rigid support provided by the sheet metal, thereby taking into account the triple functions of sealing, dust prevention and guidance. The end of the light guide strip 22 furthest from the second lampshade 23 is guided to the transverse interlayer space between the window glass 5 and the inner door panel 6. This fully utilizes the narrow gap between the glass and the interior panel, allowing light to be emitted discreetly without occupying effective space inside the door or affecting the window's operation or the interior's appearance. Simultaneously, this arrangement allows light to be projected at a controlled angle at the end of the light guide strip 22, forming a continuous light band along the inner edge of the window glass 5. The inner door panel 6 then shields the light from direct light from its back, preventing glare from entering the occupants' field of vision. Through the tight coupling of the light guide strip 22 and the second lampshade 23, the stable clamping with the inner window deflector 4, and the precise alignment with the glass-inner panel interlayer, the entire light transmission path maintains efficient light guiding and uniform scattering while also ensuring structural concealment, sealing integrity, and assembly reliability. This achieves a soft presentation of the ambient light strip inside the vehicle and a unified design effect for the entire interior.

[0057] In any of the above embodiments, light is transmitted to the illumination area of ​​the window glass 5 via the first port, and the lateral corresponding light is transmitted to the illumination area of ​​the window glass 5 via the end of the light guide strip 22.

[0058] In this embodiment, when the vehicle is powered on, the light emitted by the first light-emitting part is first uniformly shaped in the first groove by the first lampshade 12, and then projected along the thickness direction of the window glass 5 through the first port to form a first illumination area located at the outer edge of the glass and extending continuously. At the same time, the light emitted by the second light-emitting part after being shaped by the second lampshade 23 is transmitted to the far end of the light guide strip 22 integrally connected thereto, and then passes through the second port to the inner edge of the glass through the far end to form a second illumination area located at the inner edge of the glass. Since the two light paths correspond to each other in the thickness direction of the glass and overlap laterally on the horizontal projection surface, the outer light strip and the inner light strip are aligned at the edge of the glass, thus visually outlining a continuous, uniform and three-dimensional halo effect, which not only enhances the recognizability of the vehicle body appearance, but also creates a soft and enveloping ambient lighting in the cabin. Moreover, the entire light path layout does not damage the sealing and guiding function of the water deflector and the door sheet metal-glass interlayer, achieving a synergistic unity of light efficiency consistency, structural concealment and sealing integrity.

[0059] In any of the above embodiments, the light guide assembly further includes: The velvet strip 21 is positioned on the side of the light guide strip 22 facing the car window glass 5.

[0060] In this embodiment, to further improve the softness and uniformity of the light strip on the inner edge of the vehicle, a velvet strip 21 is added to the light guide assembly, and the velvet strip 21 is positioned on the side of the light guide strip 22 facing the window glass 5, so that it forms a close covering relationship with the light guide strip 22. When the light generated by the second light source 24 after being shaped by the second lampshade 23 is transmitted along the light guide strip 22 to the far end of the light guide strip 22 and transmitted to the inner edge of the window glass 5, the light first passes through the interface between the light guide strip 22 and the velvet strip 21, and then undergoes multiple scattering and refraction in the micro-flocked fibers of the velvet strip 21, thereby significantly reducing the point or line-like light. The glare from the strong light further diffuses the originally locally concentrated beam of light into a soft and continuous surface light, ultimately forming a uniform, delicate, and non-glaring light band effect at the edge of the window glass 5. At the same time, the velour strip 21 itself has the characteristics of flexibility, wear resistance and noise reduction. Its surface maintains a slight adaptive fit with the window glass 5, which not only plays a role in reducing friction, noise reduction and dust particle isolation during the glass raising and lowering process, preventing the hard light guide strip 22 from directly scratching the glass and causing scratches, but also further seals any micro gaps that may exist between the light guide strip 22 and the glass, and works with the inner water deflector strip 4 of the window to improve the sealing performance. In addition, the velvet strip 21 covering the outer surface of the light guide strip 22 can also cover the structural outline of the light guide strip 22 body that may be exposed, enhance the hiding effect, and prevent the passenger side from looking directly at the light source under the back cover of the inner door panel 6, effectively ensuring the visual comfort of the cabin.

[0061] In summary, the close fit, optical diffusion, and mechanical buffering between the velour strip 21, the light guide strip 22, the inner window water deflector strip 4, and the second light-emitting part not only improve the visual quality of the inner side light strip, but also further enhance the overall structure's sealing, durability, and quiet operation.

[0062] A second aspect of the present invention provides an illumination method. In some embodiments of the present invention, such as... Figure 3 As shown, the lighting method includes the following steps: S101, turn on the vehicle power and supply power to the first and second light-emitting parts.

[0063] S102, the first light-emitting part projects light from outside the vehicle onto the side wall edge of the window glass 5 through the first port.

[0064] S103, the second light-emitting part projects light from inside the vehicle to the side wall edge of the window glass 5 through the light guide assembly.

[0065] S104, the window glass 5 illuminates the interior of the vehicle by receiving light through both the inner and outer side walls.

[0066] The present invention provides a lighting method in which, when the driver starts the vehicle power, the vehicle immediately supplies power to the first light-emitting part pre-embedded in the first groove of the outer water deflector strip 3 of the window and the second light-emitting part arranged in the second groove of the inner water deflector strip 4 of the window. This action activates the power-on and light-emitting functions of the first light source 11 and the second light source 24, and ensures that the two independent light paths start working at the same time reference, thus laying the foundation for the synchronization of the subsequent light in the thickness direction of the window glass 5.

[0067] Driven by electric power, the first light-emitting part first continuously generates uniform linear light along its length direction. Under the shaping and limiting effect of the first lamp cover 12, it is directed to the outer edge of the window glass 5 at a controlled angle through the first port set near the glass side of the outer water deflector 3. After passing through the glass thickness and refraction interface, this beam of light can outline a smooth, continuous and concealed contour light strip on the side of the vehicle body at night, providing a striking side recognition effect for driving and adding a high-end light trim texture to the overall appearance of the vehicle.

[0068] Almost simultaneously, the second light-emitting part forms an internal beam under the covering and shaping effect of the second lampshade 23, which extends towards the window glass 5 via the light guide assembly integrally connected to the second lampshade 23; the beam is transmitted along the light guide strip 22 to its far end and then crosses the second port, and finally passes through the velour strip 21 for further scattering and softening, and is evenly projected onto the inner edge of the window glass 5. Since the light guide strip 22 is blocked by the inner door panel 6, and the velour strip 21 converts the excessively bright point beam into a surface light distribution, the occupants can only feel the soft and smooth edge light strip without looking directly at the light source, thus creating an interior lighting effect that combines a sense of enclosure and atmosphere inside the cabin.

[0069] When the outer light and the inner light are projected through the first port and the end of the light guide strip 22 respectively, they are aligned front and back in the thickness direction of the window glass 5, and a three-dimensional and continuous "halo" appears at the edge of the glass. The outer light strip enhances the visibility and recognizability of the whole vehicle at night, while the inner light strip provides comfortable, glare-free and layered ambient lighting for the occupants. The two are superimposed, so that the glass body can simultaneously act as a light guiding medium and a body sealing component, which significantly improves the overall lighting quality of the vehicle without damaging the original waterproof, dustproof and noise reduction performance of the water deflector.

[0070] Through the above four-step connection sequence, the entire lighting method does not require additional openings or occupy the interior space of the car door in terms of structure. In terms of function, it achieves a synergistic unity of aesthetic appearance, safety identification and cabin ambient lighting. At the same time, relying on the flexible embedding characteristics of the water deflector, it ensures that the light-emitting components can be quickly assembled, easily maintained and have good durability, thus improving the overall safety of the vehicle at night, the personalized experience of the user and the premium feel of the vehicle interior.
