[0003] However, the inventors discovered that existing ambient light housings are mostly assembled from multiple parts. Due to the unavoidable gaps between these parts, light leakage is a significant problem, affecting the overall lighting effect and aesthetic appeal of the ambient light, thus reducing the product's perceived quality and user experience. Utility Model Content
[0004] The purpose of this utility model is to provide a lampshade and lighting assembly that, by adopting an integrated molding structure, effectively solves the light leakage problem caused by the splicing of parts in the prior art, thereby improving the light effect and appearance quality of the ambient light and further enhancing the user experience.

Detailed Implementation
[0019] In related technologies, the outer shell of ambient lights is often assembled from multiple parts. Due to the unavoidable gaps between the parts, light leakage is a prominent problem.
[0020] To address the aforementioned issues, this utility model provides a lampshade and lighting assembly. By adopting an integrated molding structure, it effectively solves the light leakage problem caused by the splicing of parts in the prior art, thereby improving the lighting effect and appearance quality of the ambient light and further enhancing the user experience.
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0024] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0025] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0026] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0027] The following describes in detail the overall structure, working principle, and technical effects of the lampshade and lighting assembly provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0028] Please see Figure 1 and Figure 2 This utility model provides a lampshade 101, applied to a lighting assembly 10. The lampshade 101 includes a first shielding portion 100, a second shielding portion 300, and a connecting portion 200 disposed between the first shielding portion 100 and the second shielding portion 300. It should be noted that the shielding portion is a physical shield for the intermediate light conductor, rather than a shield for the light itself.
[0029] Based on the above, the first shielding part 100, the second shielding part 300 and the connecting part 200 are integrally formed, which effectively reduces the gap problem caused by assembly gaps in traditional multi-part splicing structures, thereby effectively avoiding light leakage at the structural level and significantly improving the consistency, aesthetics and user experience of the product.
[0030] Therefore, the connecting portion 200 is bent into an arc shape, allowing the second shielding portion 300 to rotate relative to the first shielding portion 100 and connect to the end of the first shielding portion 100 away from the connecting portion 200, thereby jointly enclosing and forming a receiving chamber 400 for accommodating the light guide 103. Correspondingly, the first shielding portion 100 is provided with a light-transmitting portion 110 corresponding to the light-receiving member 20 to achieve effective light transmission; while the second shielding portion 300 and the connecting portion 200 are both non-transparent structures used to block light leakage in non-target areas, thereby further improving the overall lighting quality and aesthetic appearance of the lampshade 101.
[0031] Based on the above settings, that is, the lampshade 101 provided by this utility model effectively solves the light leakage problem caused by the splicing of multiple parts in existing ambient lights through the integrated molding structure, the reasonable layout of the light-transmitting part 110 and the non-light-transmitting part 130, and the bendable design of the connecting part 200, thereby improving the light effect, appearance quality and user experience.
[0032] Furthermore, it should be noted that in this embodiment, the first shielding part 100 has an overall U-shaped opening structure, which includes a bottom base and two side extension arms. The connecting part 200 is connected to the end of one side extension arm. The second shielding part 300 is bent through the connecting part 200 and forms a closed structure with the other side extension arm, thereby enclosing and forming the accommodating chamber 400.
[0033] Based on the above, such as Figures 3 to 6 As shown, this utility model also provides a lighting assembly 10, including a light guide 103 and a lampshade 101 as described in the previous embodiment. The light guide 103 is housed and fixed within a housing chamber 400. In practical applications, the light guide 103 can be a flexible light guide 103 or a rigid light guide 103, which works in conjunction with an external light source 40 (such as an LED chip) to guide light to the light-transmitting portion 110 of the lampshade 101 and output it evenly, thereby achieving a soft and uniform lighting effect.
[0034] In some embodiments, the inner wall shape of the accommodating cavity 400 formed by the first shielding part 100 and the second shielding part 300 after being closed is adapted to the outer shape of the light guide 103, so that the light guide 103 can be stably snapped and fixed in the cavity through structural cooperation, thereby improving assembly efficiency and simplifying the production process without the need for additional fasteners or adhesive methods.
[0035] In other embodiments, such as Figure 7 As shown, the light guide 103 extends along the length of the lampshade 101 to achieve efficient light transmission and uniform output. Therefore, as Figure 1 As shown, at least two limiting portions 410 can also be provided at intervals along the length of the lampshade 101. The limiting portions 410 are connected to the inner wall of the accommodating chamber 400 (which can be the inner wall of the first shielding portion 100 or the inner wall of the second shielding portion 300) and engage with the outer surface of the light guide 103 to position and limit the light guide 103 along its length, preventing it from shifting or loosening during use.
[0036] In an optional embodiment, the limiting part 410 may be a protruding structure, with two parts symmetrically arranged on both sides of the inner wall of the accommodating chamber 400, and engaging with the outer surface of the light guide 103. It is understood that the protruding structure is in the form of a protruding block or rib with a certain height and curvature, possessing a certain elastic deformation capability. It can smoothly guide the light guide 103 through its own deformation during assembly, and restore its deformation after the light guide 103 reaches the predetermined installation position, thereby achieving an automatic locking function. Subsequently, the limiting part 410 forms friction and positioning forces through localized contact with the outer surface of the light guide 103, thereby effectively limiting the light guide 103.
[0037] To balance the limiting effect with assembly efficiency, the limiting parts 410 are preferably arranged at a spacing of approximately one every 60 mm. It is understood that this spacing design can ensure uniform force and stable limiting of the light guide 103 along its entire length, while avoiding the risk of increased assembly resistance or deformation of the light guide 103 due to overly dense limiting parts 410.
[0038] In both of the above embodiments, the light guide 103 can be made of flexible or rigid materials, and its cross-sectional shape can be as follows: Figure 8 The circle shown, as Figure 9 The square shown, such as Figure 10 The omega shape (Ω shape) or other suitable shape shown can be used. As long as the shape can match the inner wall contour of the accommodating chamber 400 or form an effective fit with the limiting part 410, a good fixing effect and alignment accuracy of the light guide 103 can be achieved, thereby ensuring the stability of the fit between the light guide 103 and the lamp cover 101 and the consistency of optical performance.
[0039] Please refer to it again. Figure 1 In this embodiment, the first shielding portion 100 further includes a non-transparent portion 130 for blocking light from non-target areas, preventing light leakage, and thereby improving the controllability and aesthetics of the overall lighting effect. The non-transparent portion 130 is connected to the connecting portion 200 and extends toward the light-transmitting portion 110 to form a non-transparent layer 123. Correspondingly, the light-transmitting portion 110 extends toward the non-transparent portion 130 to form a light-transmitting layer 121.
[0040] Based on the above, the light-transmitting layer 121 is located below the opaque layer 123 and together with the opaque layer 123 forms a transition portion 120. It can be understood that this transition portion 120 achieves effective integration between the light-transmitting layer 121 and the opaque layer 123, ensuring that they can form a stable integrated structure, enhancing the structural connection stability between the two, and thus improving the mechanical strength of the first shielding portion 100 and even the lampshade 101 as a whole.
[0041] Furthermore, to ensure that the transition portion 120 has sufficient structural connection strength to improve the overall mechanical stability and assembly reliability of the first shielding portion 100, the extension length S1 of the transition portion 120 is in the range of: S1≥3mm. It should be noted that the extension length S1 of the transition portion 120 refers to the overlap length of the light-transmitting layer 121 and the non-light-transmitting layer 123 in the overlapping direction.
[0042] In this design, if the extension length S1 is less than 3mm, the overlap area between the light-transmitting layer 121 and the non-light-transmitting layer 123 will be significantly reduced, which may result in an insufficiently strong connection between the two, thereby affecting the overall strength and service life of the first shielding part 100 structure. Furthermore, during actual assembly or use, external forces or temperature changes may cause structural failures such as cracking or peeling between the light-transmitting layer 121 and the non-light-transmitting layer 123, affecting the reliability and optical performance of the product.
[0043] Therefore, by setting S1 to be no less than 3mm, not only can the structural connection stability between the light-transmitting layer 121 and the non-light-transmitting layer 123 be enhanced, but the deformation resistance of the lampshade 101 during molding, assembly and use can also be improved to a certain extent, thereby ensuring its long-term reliability and performance consistency.
[0044] Furthermore, the structural design of the first shielding portion 100 has certain regional differences along the length of the lampshade 101 to adapt to the optical functional requirements of different positions. Specifically, along the length of the lampshade 101, such as... Figure 11 As shown, a portion of the cross-section of the first shielding part 100 consists only of the non-transparent part 130; as Figure 12 As shown, only the light-transmitting portion 110 of the cross-section is visible; as... Figure 13 As shown, a portion of the cross-section includes a light-transmitting portion 110 and a non-light-transmitting portion 130.
[0045] For example, such as Figure 11 As shown, in the area of the lighting assembly 10 corresponding to the light source 40 (such as the part where the light guide 103 connects to the external light source 40) or in areas where the mixing lamp does not need to transmit light, the first shielding part 100 at this location has only a non-transparent part 130 in its cross-section. This prevents light from directly leaking out of the area of the light source 40, ensuring that light is effectively conducted through the light guide 103, thereby improving the controllability of the overall lighting effect. Accordingly, as... Figure 12 and Figure 13 As shown, in the area corresponding to the light-receiving member 20, the cross section of the first shielding part 100 is provided with only the light-transmitting part 110 or includes the light-transmitting part 110 and the non-light-transmitting part 130, so as to achieve efficient output and uniform distribution of light and meet the needs of lighting or decorative light effects.
[0046] Furthermore, when a cross-section of the first shielding portion 100 simultaneously includes a light-transmitting portion 110 and a non-light-transmitting portion 130, the specific arrangement of the light-transmitting portion 110 can have various structural forms to meet different optical performance and structural design requirements. For example, such as Figure 13 As shown, the light-transmitting portion 110 can be disposed between two opaque portions 130, and its two ends respectively form transition portions 120 with the two opaque portions 130. On the other hand, as Figure 5As shown, the cross-sectional structure of the first shielding part 100 can also be: the side near the connecting part 200 is a non-transparent part 130, which is used to shield the connecting area to prevent light leakage; while the side away from the connecting part 200 is a transparent part 110, which is used to achieve effective output and diffusion of light, thereby meeting the needs of lighting or decorative lighting effects.
[0047] It should be noted that this embodiment does not limit the specific placement of the light-transmitting portion 110 within the cross-section of the first shielding portion 100. It can be adaptively configured according to the actual application scenario, optical design goals, and structural functional requirements. For example, in some areas, the light-transmitting portion 110 can be centrally located to achieve a symmetrical lighting effect; in other areas, the light-transmitting portion 110 can be offset to one side to adapt to lighting needs in a specific direction. Furthermore, the shape, thickness, relative position to the non-light-transmitting portion 130, and transition method of the light-transmitting portion 110 can also be adjusted according to the actual application to further optimize optical performance and structural reliability.
[0048] To ensure a stable connection between the second shielding part 300 and the end of the first shielding part 100 furthest from the connecting part 200, thereby guaranteeing good structural stability and sealing of the accommodating chamber 400 formed by the first shielding part 100, the second shielding part 300, and the connecting part 200, and effectively preventing displacement of the light guide 103 during use or light leakage due to structural loosening, one of the first shielding part 100 and the second shielding part 300 is provided with a buckle 150, and the other is provided with a corresponding slot 311 that matches the buckle 150. That is, the first shielding part 100 and the second shielding part 300 achieve a detachable locking connection through the cooperation of the buckle 150 and the slot 311.
[0049] Specifically, the structural design of the buckle 150 and the slot 311 not only enables the quick assembly and disassembly of the second shielding part 300 and the first shielding part 100, improving assembly efficiency, but also provides sufficient connection strength in the assembled state to effectively resist the influence of environmental factors such as external vibration, temperature changes or mechanical impact on the structure of the lampshade 101, thereby ensuring the structural integrity and functional stability of the lampshade 101 as a whole during long-term use.
[0050] Furthermore, the buckle 150 may be provided with a guide slope or an elastic deformation structure to facilitate the buckle 150 sliding smoothly into the slot 311 and achieving automatic locking during assembly; at the same time, this structure can also reduce assembly resistance and prevent damage to components due to hard impacts. Correspondingly, the slot 311 is provided with a limiting structure that matches the shape of the buckle 150 to ensure that the buckle 150 is not easy to fall off after being fastened, thereby further improving the stability and reliability of the connection.
[0051] In some embodiments, the end of the second shielding portion 300 away from the connecting portion 200 is folded to form a folded portion 310, and the folded portion 310 is provided with a slot 311. Correspondingly, the first shielding portion 100 is provided with a buckle 150 on the side near the folded portion 310. Based on this, a tight fit can be achieved between the second shielding portion 300 and the first shielding portion 100 when the lampshade 101 is closed, effectively improving the overall sealing performance of the lampshade 101 and further ensuring the stable operation and optical performance of the light guide 103 assembly.
[0052] Furthermore, since the second shielding portion 300 adopts a non-transparent structure, the folding portion 310 is also a non-transparent structure. After the second shielding portion 300 is closed, the folding portion 310 can effectively block the light-transmitting portion 110 on the first shielding portion 100, thereby further defining the light-emitting area, improving the concentration and aesthetics of the light output, preventing light leakage from non-target areas, and enhancing the controllability and luminous efficacy of the lampshade 101 in the overall lighting effect.
[0053] It should be understood that the specific number, position, shape, and distribution of the clips 150 and slots 311 can be adaptively designed according to the actual size of the lampshade 101, assembly requirements, and structural strength requirements, and are not limited to the description in this embodiment. For example, multiple clips 150 and slots 311 can be provided at multiple positions on the second shielding part 300 and the first shielding part 100 to enhance the uniformity of the connection and improve the stability and load-bearing capacity of the overall structure. In this embodiment, the clips 150 can be arranged at a spacing of approximately one every 60 mm to ensure connection strength while also taking into account assembly efficiency.
[0054] In other embodiments, such as Figure 14 As shown, without the folding portion 310, the second shielding portion 300 and the end of the first shielding portion 100 furthest from the connecting portion 200 can also be connected by adhesive. In this case, a dedicated bonding area can be provided at the contact point between the second shielding portion 300 and the first shielding portion 100, and suitable adhesives or other bonding processes, such as hot melt bonding or ultrasonic welding, can be used to achieve a fixed connection with high strength and good sealing performance. This method is particularly suitable for applications with high sealing requirements or where frequent disassembly is not required.
[0055] To ensure the connecting portion 200 has good bendability, enabling the second shielding portion 300 to smoothly fold and close relative to the first shielding portion 100, the cross-sectional thickness of the connecting portion 200 is less than that of the first shielding portion 100 and less than that of the second shielding portion 300. It should be understood that by reducing the cross-sectional dimensions of the connecting portion 200, its structural resistance during bending can be effectively reduced, improving flexibility and ease of operation, thereby ensuring the structural adaptability and process feasibility of the lampshade 101 during assembly and use.
[0056] Furthermore, the cross-sectional thickness D1 of the connecting part 200 is within the range of 0.5mm ≥ D1 ≥ 0.2mm. It should be noted that the above thickness range ensures that the connecting part 200 has a certain structural strength to withstand the external forces that may be applied during assembly and use, while also preventing excessive thickness from causing bending difficulties or affecting the flexibility of the overall structure.
[0057] Furthermore, to ensure that the connecting part 200 has sufficient ductility and contact area during bending to achieve a stable connection between the second shielding part 300 and the first shielding part 100, the extension length D2 of the connecting part 200 is in the range of D2 ≥ 1.5 mm. It should be noted that this extension length helps improve the structural stability of the connecting part 200 after it is bent into an arc shape, preventing loosening or insufficient strength at the connection due to insufficient length, thereby ensuring the overall sealing performance and long-term reliability of the lampshade 101.
[0058] Based on the above, in this utility model, the connecting part 200, as a flexible connection structure between the first shielding part 100 and the second shielding part 300, not only undertakes the function of folding and opening the second shielding part 300, but also ensures the structural stability and sealing after bending through its specific thickness and extension length design. At the same time, the connecting part 200 and the second shielding part 300 together form a non-transparent structure, effectively preventing light leakage from the connection area.
[0059] Furthermore, it should be noted that in practical applications, the lampshade 101 is manufactured using a two-color injection molding process, forming a single, integrated component with a complete structure and functions. To ensure good bonding between the materials of the two different functional areas (the light-transmitting part 110 and the non-light-transmitting part 130) during the molding process, and to avoid structural strength reduction or molding defects due to material incompatibility, the light-transmitting part 110, the non-light-transmitting part 130, and the non-light-transmitting structures (such as the connecting part 200 and the second shielding part 300) are all made of polypropylene (PP) materials to achieve good material compatibility and process adaptability.
[0060] The non-transparent section 130 and the non-transparent structure are used to block light from non-target areas, prevent light leakage, and improve the overall light control performance and aesthetic appearance of the lampshade 101. This part is preferably made of polypropylene material with 20% talc added, namely PP-TD20. It should be noted that this material not only has good mechanical strength and heat resistance.
[0061] The light-transmitting part 110 is made of polypropylene material with light-diffusing properties, such as material with grade 9802TD (9802 Transparent Diffuse). It has good light transmittance and light scattering ability, which can uniformly diffuse the light from the light guide 103, thereby achieving a soft and uniform lighting effect, avoiding the problem of local bright spots or glare, and improving visual comfort and decoration.
[0062] Please see Figures 15 to 17 In the embodiment where the lighting assembly 10 provided by this utility model is applied to automotive interior components, the lighting assembly 10 is particularly suitable for interior lighting scenarios in modern automobiles where aesthetic and functional requirements are increasingly demanding. Specifically, the lighting assembly 10 can be adaptably arranged in multiple key areas inside the automobile, such as complex curved areas like the dashboard, sub-dashboard, door trim panels, side trim strips, seat backs, headliner, and center armrest, to meet diverse ambient and functional lighting needs.
[0063] In actual installation, the lighting assembly 10 (specifically, the lampshade 101 within the lighting assembly 10) can be fixed to the surrounding parts 30 using adhesive, screws, clips, or other conventional fastening methods. Furthermore, the connection points between the lighting assembly 10 and the surrounding parts 30 are spaced apart along the length of the lampshade 101, with a spacing of 60 to 80 mm, to ensure installation stability while also considering assembly efficiency and structural strength. It should be noted that this connection method is also applicable to ambient lighting arrangements with curved structures, effectively adapting to complex curved surfaces in automotive interiors and ensuring the stability and aesthetics of the lighting assembly 10 under different installation angles and curvatures.
[0064] The light source 40 is disposed at one or more positions of the lighting assembly 10 to emit light, which is then uniformly guided through the light guide 103 to the light-transmitting part 110 of the lamp cover 101, and finally output outward from the light-transmitting part 110 to form a soft and uniform lighting effect. The light source 40 can be an LED chip, a flexible LED strip, or other light source 40 components suitable for the light guide system, which is connected to the vehicle power system through wires to achieve power-on illumination.
[0065] Furthermore, as mentioned above, the light-receiving element 20 is correspondingly disposed to the light-transmitting portion 110 of the lampshade 101, and is used to receive and display the light transmitted by the light guide 103, thereby achieving specific lighting effects or decorative lighting effects. In practical applications, the light-receiving element 20 can be made of various materials with different textures, colors, and materials to achieve diverse visual effects. For example, the light-receiving element 20 can be made of leather, fabric, PVC film, PC film, real wood veneer, metallic finish, or sprayed texture layer, etc., which can reflect, scatter, or absorb light, thereby presenting soft, bright, gradient, or multi-level lighting effects, achieving differentiated and customized lighting designs.
[0066] Taking the lighting assembly 10 provided by this utility model as an example, its working principle is as follows: During the assembly process, the light guide 103 is first snapped into the first shielding part 100 by the limiting part 410. Then the connecting part 200 is bent so that the second shielding part 300 can rotate relative to the first shielding part 100 and finally connects to the end of the first shielding part 100 away from the connecting part 200, thereby jointly forming a receiving cavity 400 for fixing the light guide 103.
[0067] When the lighting assembly 10 is working, the light source 40 is powered on and illuminated. The generated light enters the light guide 103 and is efficiently transmitted within it through total internal reflection. The light guide 103 evenly transmits the light along the length of the lampshade 101 to the light-transmitting portion 110 area of the first shielding portion 100. The light then passes through the light-transmitting portion 110 and is output outward, illuminating the corresponding light-receiving component 20, thereby achieving a soft and uniform lighting effect or decorative light effect output.
[0068] Throughout the entire process, the non-transparent part 130, the connecting part 200, and the second shielding part 300 of the first shielding part 100 all adopt a non-transparent structure, which effectively blocks light leakage in non-target areas, improving lighting quality and aesthetic appearance. At the same time, the lampshade 101 adopts an integrated molding structure, avoiding the light leakage problem caused by assembly gaps in traditional multi-part splicing structures, and significantly improving product consistency and assembly efficiency.
[0069] In summary, this utility model provides a lampshade 101 and a lighting assembly 10. The lampshade 101 includes a first shielding portion 100, a second shielding portion 300, and a connecting portion 200 disposed between the first shielding portion 100 and the second shielding portion 300. Furthermore, the first shielding portion 100, the second shielding portion 300, and the connecting portion 200 are integrally formed, effectively reducing the gap problem caused by assembly gaps in traditional multi-part splicing structures, thereby effectively avoiding light leakage at the structural level and significantly improving product consistency, aesthetics, and user experience. Based on the above, the connecting portion 200 is used to be bent into an arc-shaped structure, allowing the second shielding portion 300 to rotate relative to the first shielding portion 100 and connect to the end of the first shielding portion 100 away from the connecting portion 200, thereby jointly enclosing a receiving chamber 400 for accommodating the light guide 103. Accordingly, the first shielding part 100 is provided with a light-transmitting part 110 corresponding to the light-bearing member 20 to achieve effective light transmission; while the second shielding part 300 and the connecting part 200 are both non-transparent structures, used to block light leakage in non-target areas, thereby further improving the overall lighting quality and aesthetic appearance of the lampshade 101.
[0070] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
