Technical Field
[0001] This utility model relates to the field of automotive interior technology, and more specifically, to an ambient light. Background Technology
[0002] With the rapid development of the automotive industry and the increasing demands of consumers for the quality of the in-car environment, ambient lighting has become an important feature for enhancing the interior quality and personalized experience of vehicles. In recent years, more and more models have begun to adopt continuous ambient lighting designs, such as continuous dashboard, door panel trim, and ceiling ambient lighting, to create a more cohesive and luxurious visual effect.
[0003] In existing technologies, continuous ambient lighting typically requires a long light output length, usually exceeding 1500mm. Due to limitations in mold manufacturing and injection molding processes, lampshades of such length cannot be molded as a single piece using a single mold. Therefore, the traditional solution is to disassemble the lampshade into two or more sections, which are then fixed and assembled using structural components.
[0004] However, the inventors discovered that while the segmented splicing method solved the length limitation problem, it inevitably created discontinuous seams on the lampshade surface. These seams not only affected the overall aesthetics but also interfered with light propagation, thus reducing the optical effect of the ambient light and the user experience. Utility Model Content
[0005] The purpose of this invention is to provide an ambient light that can be molded in one piece using an extrusion process, thereby avoiding the generation of discontinuous seams on the surface and improving the optical effect and user experience of the ambient light.
[0006] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides an ambient light, comprising: The lampshade is an extruded structure; the cross-section of the lampshade is the same at any position along the length of the ambient light. The bracket is connected to the lampshade and together with the lampshade, they form a receiving cavity. The light guide is located inside the accommodating cavity.
[0007] In an optional embodiment, the outer surface of the lampshade is provided with a light-transmitting protrusion, and the light-transmitting protrusion extends along the length direction of the ambient light.
[0008] In an optional implementation, the height d of the light-transmitting protrusion is in the range of d≥1mm.
[0009] In an optional implementation, the lampshade is a light-transmitting structure, while the bracket is an opaque structure.
[0010] In an optional embodiment, the light guide includes a reflective part and a light-emitting part; wherein the reflective part is used to reflect the introduced light to the light-emitting part, and the light-emitting part is used to guide the light to the lampshade.
[0011] In an optional implementation, the bracket snaps into the lampshade.
[0012] In an optional embodiment, the lampshade has a first U-shaped structure and the bracket has a second U-shaped structure; the second U-shaped structure is disposed opposite to the open end of the first U-shaped structure, and is at least partially located inside the first U-shaped structure, and is engaged with the first U-shaped structure.
[0013] In an optional embodiment, one of the first U-shaped structure and the second U-shaped structure is provided with a snap-fit portion, and the other is provided with a snap-fit groove that mates with the snap-fit portion.
[0014] In an optional embodiment, the first U-shaped structure includes a top wall and two first side walls, the two first side walls being connected to the two sides of the top wall at an angle. The second U-shaped structure includes a bottom wall and two second side walls, which are connected to the two sides of the bottom wall at an angle. One of the first and second sidewalls is provided with a snap-fit part, and the other is provided with a snap-fit groove.
[0015] In an optional implementation, there are multiple snap-fit parts, and each snap-fit part corresponds to a snap-fit slot.
[0016] The beneficial effects of the ambient light provided in this embodiment of the utility model include: This utility model embodiment provides an ambient light, which includes a lampshade, a bracket, and a light guide. The bracket is connected to the lampshade and together they form a receiving cavity. The light guide is disposed within the receiving cavity to receive light from the light source and guide and distribute the light, thereby achieving a soft and uniform lighting effect. Based on the above, the lampshade is an extruded structure, integrally and continuously formed using an extrusion process, avoiding seam problems caused by splicing, thus significantly improving the overall appearance consistency of the lampshade. In other words, the lampshade formed by the extrusion process has the technical advantage of being ultra-long and seamless. Therefore, along the length of the ambient light, the cross-section of the lampshade is the same at any position, which helps the light to propagate and emit uniformly within the lampshade, improving the stability of the overall light output effect and enhancing optical performance.

Detailed Implementation
[0020] In existing technologies, lampshades are made by segmenting and splicing, resulting in discontinuous seams on the surface. These seams affect the overall aesthetics and interfere with light transmission, thereby reducing the optical effect and user experience of the ambient light.
[0021] To address the aforementioned issues, this invention provides an ambient light with an extruded lampshade, which avoids discontinuous seams on the surface and improves the optical effect and user experience of the ambient light.

[0027] 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.
[0028] The following describes in detail the overall structure, working principle, and technical effects of the ambient light provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0029] Figure 1 This is an exploded view of the ambient light 10 provided in this embodiment. Figure 2 This is a schematic diagram of the structure of the ambient light 10 provided in this embodiment. Please refer to [link / reference]. Figure 1 and Figure 2 This utility model provides an ambient light 10, which is applied to the field of automotive interior technology. It can effectively avoid the problem of discontinuous seams on the surface of the lamp cover 100, thereby improving the optical effect and user experience of the ambient light 10.
[0030] The ambient light 10 includes a lampshade 100, a bracket 300, and a light guide 500. The bracket 300 is connected to the lampshade 100 and together with the lampshade 100, they form a receiving cavity 400. The light guide 500 is disposed within the receiving cavity 400 and is used to receive light from the light source and guide and distribute the light to achieve a soft and uniform lighting effect.
[0031] Based on the above, the lampshade 100 is an extrusion-molded structure, manufactured using an extrusion process. It should be noted that extrusion is a continuous molding process, which mainly involves extruded heated molten material (such as plastic, rubber, or metal) through a die of a specific shape to form a profile of continuous length. Subsequent processes such as cooling, shaping, traction, and cutting are then used to obtain the final product.
[0032] Based on this, it can be understood that the lampshade 100 made by the extrusion process can be designed to any required length, which is suitable for ambient lights 10 with high length requirements, such as lamp designs with a length of more than 1500mm or even longer.
[0033] Compared with the traditional injection molding process that requires segmenting the lampshade 100 and then splicing it together, this utility model achieves integrated continuous molding of the lampshade 100 through extrusion process. While ensuring the required length, it avoids the seam problem caused by splicing, thereby significantly improving the overall appearance consistency and aesthetics of the lampshade 100.
[0034] This means that the lampshade 100 formed by extrusion has the technical advantage of being extremely long and seamless. Therefore, as Figures 3 to 5 As shown, the cross-section of the lampshade 100 is the same at any position along the length of the ambient light 10, which helps the light to spread and emit evenly inside the lampshade 100, improves the stability of the overall light output effect, and enhances the optical performance.
[0035] It should be noted that the bracket 300 also extends along the length of the ambient light 10, and its extension shape matches that of the lampshade 100 to ensure the overall structural harmony and assembly stability. In some optional embodiments, the bracket 300 can also be an extruded structure, manufactured using an extrusion process, achieving continuous molding along the length direction like the lampshade 100, thereby ensuring structural consistency over long dimensions.
[0036] In addition, in the embodiments provided in this application, the light guide 500 is a structural component made of optical-grade transparent plastic, which has good light transmission performance, light conduction performance and processing and molding performance. It can effectively conduct the light emitted by the light source along its length direction, and achieve directional guidance and uniform distribution of light through internal structural design.
[0037] For example, the material of the light guide 500 can be a transparent plastic material with excellent optical properties, such as polymethyl methacrylate (PMMA), polycarbonate (PC), or cyclic olefin copolymer (COC). These materials have advantages such as high light transmittance, stable refractive properties, and good weather resistance. They are also easy to mold through processes such as extrusion and injection molding, making them suitable for manufacturing light guide 500 structures of different shapes and sizes, and offering good process adaptability and application flexibility.
[0038] Depending on the actual application scenario and assembly space, the light guide 500 can be made of either soft or hard materials. For example, when the installation space of the ambient light 10 has certain bending or arc-shaped structural requirements, a flexible soft light guide 500 material can be used to adapt to the structural requirements of non-linear arrangement; while in situations where high structural rigidity is required and optical path stability needs to be maintained, a hard light guide 500 material can be selected to ensure that the light guide 500 has good morphological stability and optical consistency during use.
[0039] Furthermore, in an optional embodiment of this utility model, such as Figure 4 As shown, the light guide 500 includes a reflective part 510 and a light-emitting part 530. The reflective part 510 is used to reflect the introduced light to the light-emitting part 530, and the light-emitting part 530 is used to guide the light to the lampshade 100, thereby achieving a uniform and soft lighting effect.
[0040] During operation, the light source can be positioned at one or more locations within the ambient light 10. The emitted light enters the light guide 500 and propagates along its length. When the light reaches the reflector 510, some of the light is directionally reflected and transmitted to the light-emitting section 530, while the remaining light bypasses the reflection process and directly enters the light-emitting section 530. The light-emitting section 530 further guides the received light to the lampshade 100, which then evenly emits the light into the external environment, thereby achieving a continuous, soft, and visually appealing lighting effect.
[0041] The reflector 510 can adopt any existing structure suitable for light reflection, as long as it can effectively reflect light. For example, but not limited to, the reflector 510 can be a reflective layer disposed in the light guide 500 or an optical feature structure with the function of destroying total internal reflection. The light emitting part 530 preferably protrudes towards the lampshade 100 to form an arc-shaped structure. This arc-shaped structure helps to improve the distribution of light inside the light guide 500, so that the light enters the lampshade 100 in a more uniform and softer manner, thereby improving the overall light emission effect and visual comfort of the ambient light 10.
[0042] Specifically, such as Figure 4 and Figure 5As shown in the embodiment provided in this application, the reflective part 510 is disposed on the side of the light guide 500 near the bracket 300, that is, as a reflective layer coated on the bottom of the main body of the light guide 500, and is made of a high reflectivity material (such as silver, aluminum or high reflectivity plastic coating) to enhance the reflection efficiency of incident light; the light emitting part 530 is disposed on the side of the light guide 500 near the lamp cover 100, that is, the top of the main body of the light guide 500, and is an arc-shaped or hemispherical protrusion structure to effectively guide the light reflected from the light source and the reflective layer to the lamp cover 100, thereby achieving a uniform and soft light emission effect.
[0043] Furthermore, the lampshade 100 is a light-transmitting structure, while the bracket 300 is an opaque structure. Specifically, the lampshade 100 is made of a light-transmitting material, such as light-transmitting plastic, glass, or other light-diffusing materials, to evenly project the light transmitted by the light guide 500 outwards, achieving a soft and aesthetically pleasing lighting effect. The bracket 300, as the supporting structure for the lampshade 100, is made of an opaque material, such as opaque plastic or metal, to prevent light leakage from non-light-emitting directions.
[0044] Based on the difference in optical performance between the bracket 300 and the lampshade 100, the combination can effectively prevent light from leaking from unexpected directions and prevent stray light interference, thereby improving the overall light output directionality and lighting effect of the ambient light 10; on the other hand, it also helps to enhance the contrast of the light output area and further improve its visual performance.
[0045] Furthermore, in the embodiments of this utility model, the optical performance of the lampshade 100 can not only be optimized by reasonably selecting materials, but its light emission effect can also be further improved by structural design.
[0046] Please refer to it again. Figure 4 and Figure 5 The outer surface of the lampshade 100 is provided with a light-transmitting protrusion 111, and the light-transmitting protrusion 111 extends along the length direction of the ambient light 10 so that the light can be more evenly propagated and emitted in this direction inside the lampshade 100, thereby avoiding the appearance of local bright spots or dark areas.
[0047] In practical applications, when light enters the lampshade 100 from the light guide 500, it undergoes multiple reflections and refractions inside. The light-transmitting protrusion 111 can serve as a local light scattering point, making the light more evenly distributed on the overall surface of the lampshade 100, and finally emitted to the outside in a soft and continuous manner, thus improving the visual effect of the lighting.
[0048] It is understandable that the light-transmitting protrusion 111 and the lampshade 100 are integrally formed, that is, as mentioned above, they are directly formed by extrusion process, thereby ensuring the continuity and consistency of the overall structure and avoiding optical inhomogeneity caused by segment splicing.
[0049] In addition, it should be noted that the shape of the light-transmitting protrusion 111 can be hemispherical, conical, prism, or other geometric structures suitable for light control. The specific shape can be selected and designed according to actual optical needs to achieve the best light output effect.
[0050] In the embodiments provided in this application, such as Figure 4 and Figure 5 As shown, the cross-sectional area of the light-transmitting protrusion 111 gradually decreases along the direction away from the lampshade 100, and the whole is arranged in a conical structure.
[0051] Furthermore, the height d of the light-transmitting protrusion 111 is within the range of d ≥ 1 mm. It should be noted that this height design not only helps to enhance the lampshade 100's ability to control light, enabling more uniform scattering and emission of light within the lampshade 100, but also helps to improve the structural strength of the light-transmitting protrusion 111, ensuring its stability and durability during long-term use.
[0052] in addition, Figure 6 This is a schematic diagram showing the interaction between the ambient light 10 and surrounding components provided in this embodiment, as shown below. Figure 6 As shown, the light-transmitting protrusion 111 can also be used for positioning and cooperation with the surrounding components of the ambient light 10. That is, by extending the structure in the height direction, the lampshade 100 and the surrounding components are fixed and assembled, thereby improving the overall assembly efficiency and structural stability.
[0053] It is understandable that the fixing methods between the lampshade 100 and the surrounding components include, but are not limited to, conventional connection methods such as snap-fit, welding or screw connection, and the specific method can be adapted to the actual assembly requirements, process conditions and product design.
[0054] For example, interlocking buckles and slots can be provided on the lampshade 100 and surrounding components to enable quick assembly; or ultrasonic welding, laser welding and other processes can be used to achieve a firm connection between the lampshade 100 and surrounding components; or, corresponding mounting holes can be provided on the lampshade 100 and surrounding components, and screw fasteners can be used to connect them to achieve reliable mechanical fixation.
[0055] In addition, the surface of the bracket 300 will be fixedly connected with the corresponding peripheral components according to the installation and fixing requirements, so as to securely install the ambient light 10 in the designated position of the car interior system, such as the dashboard, door panel or headliner.
[0056] Please refer to it again. Figure 4 and Figure 5The bracket 300 is snapped into the lampshade 100. This snap-fit connection provides excellent detachability, facilitating future maintenance and replacement. Furthermore, it eliminates the need for additional mounting holes or welding, maintaining the structural integrity of both the lampshade 100 and the bracket 300. It also helps ensure that the cross-section of the lampshade 100 remains consistent at any location, preventing adverse effects on optical performance or appearance quality caused by the manufacturing process.
[0057] Specifically, the lampshade 100 has a first U-shaped structure, and the bracket 300 has a second U-shaped structure. Based on this, the open ends of the second U-shaped structure are positioned opposite to those of the first U-shaped structure, and the second U-shaped structure is at least partially located within the first U-shaped structure, forming a nested assembly structure. In this nested assembly structure, the first U-shaped structures are interlocked with each other.
[0058] It should be further explained that after the first U-shaped structure and the second U-shaped structure are engaged, they together form the aforementioned accommodating cavity 400 for accommodating the light guide 500. This accommodating cavity 400 is a sealed structure, which can effectively protect the light guide 500 from dust, moisture, and mechanical damage, preventing the external environment from adversely affecting the optical performance of the light guide 500, thereby improving the overall stability and service life of the ambient light 10.
[0059] Alternatively, in other embodiments, at least a portion of the first U-shaped structure may be located within the second U-shaped structure. As long as the effective formation and sealing of the accommodating cavity 400 can be guaranteed, it should fall within the protection scope of this utility model.
[0060] In this invention, both the lampshade 100 with a first U-shaped structure and the bracket 300 with a second U-shaped structure can be formed by extrusion. By designing a matching mold, it is ensured that the lampshade 100 and the bracket 300 have a continuous and consistent cross-sectional structure in the length direction, meeting the high requirements of the through-type ambient light 10 for structural continuity and appearance consistency.
[0061] In the specific manufacturing process, taking lampshade 100 as an example, its extrusion process involves heating thermoplastic materials (such as PMMA, PC, etc.) to a molten state and feeding them into an extruder. The material is uniformly plasticized under the pushing and shearing action of the screw and then enters a specially designed die through a metering section. At this point, the die's cross-section is designed to match the U-shaped dimensions of the first U-shaped structure, thus extruding the molten material to form a continuous U-shaped profile. Subsequently, this profile enters a cooling and shaping device, where it is rapidly solidified through water cooling or air cooling to maintain its shape stability. Finally, after processes such as traction and length cutting, the desired length of lampshade 100 with the first U-shaped structure is obtained.
[0062] Similarly, the second U-shaped structure of the bracket 300 can also be manufactured using the same extrusion process, with the die orifice designed to the corresponding U-shaped size according to the requirements of the second U-shaped structure.
[0063] Based on the above, it is understandable that using extrusion process to manufacture lampshade 100 and bracket 300 can not only achieve efficient and continuous production of lampshade 100 and bracket 300, but also allow structures such as light-transmitting protrusion 111 to be formed in the mold design stage, achieving integrated manufacturing, avoiding subsequent processing, and improving production efficiency and product consistency.
[0064] Furthermore, one of the first U-shaped structure and the second U-shaped structure is provided with a snap-fit portion 210, and the other is provided with a snap-fit groove 220 that mates with the snap-fit portion 210. That is to say, the snap-fit portion 210 can be provided on the first U-shaped structure of the lampshade 100 or the second U-shaped structure of the bracket 300, and correspondingly, the snap-fit groove 220 is formed on the other structure to achieve a snap-fit engagement between the two.
[0065] For example, the snap-fit portion 210 may be disposed on the first U-shaped structure, and the snap-fit groove 220 may be disposed on the second U-shaped structure; or, according to actual design needs, the snap-fit portion 210 may be disposed on the second U-shaped structure, and the snap-fit groove 220 may be disposed on the first U-shaped structure.
[0066] Furthermore, it should be noted that the design of the snap-fit part 210 and the snap-fit groove 220 is not limited to a specific structure and can be implemented in various forms, such as, but not limited to, a combination of snap and groove, a matching structure of protrusion and groove, or other snap-fit matching methods that can achieve quick connection and stable fixation.
[0067] Specifically, the shape of the snap-fit part 210 can be a hook-shaped structure or a protrusion structure with a certain degree of elasticity; correspondingly, the snap-fit groove 220 is designed as a recessed structure or an open groove that can accommodate the snap-fit part 210 and realize the locking function, so as to ensure the stability and reliability of the connection between the two.
[0068] To achieve a stable multi-point connection between the lampshade 100 and the bracket 300, multiple snap-fit parts 210 are provided, and each snap-fit part 210 corresponds to a snap-fit groove 220. This design of multiple snap-fit parts 210 and multiple snap-fit grooves 220 not only improves the connection strength between the lampshade 100 and the bracket 300, but also enhances the overall stability and deformation resistance of the ambient light 10 structure. This effectively prevents problems such as loosening, misalignment, or detachment caused by external forces, vibrations, or temperature changes, thereby improving the reliability and durability of the ambient light 10 in actual use.
[0069] Similar to the above, multiple snap-fit parts 210 can also be formed together during the mold design stage to achieve integrated manufacturing of the structure, thereby further improving production efficiency, while ensuring the continuity and consistency of the structure, and avoiding problems such as optical interference, assembly errors or discontinuity in appearance that may be caused by using a split structure.
[0070] Please see Figure 4 and Figure 5 The first U-shaped structure includes a top wall 110 and two first side walls 130, which are connected to the two sides of the top wall 110 at an angle. In other words, the two first side walls 130 extend downward from the two sides of the top wall 110 along a set angle, forming a U-shaped opening structure.
[0071] Accordingly, the second U-shaped structure includes a bottom wall 310 and two second side walls 330, which are connected to the two sides of the bottom wall 310 at an angle. Similarly, the two second side walls 330 extend upward from the two sides of the bottom wall 310 along a set angle, and the whole structure is also U-shaped.
[0072] To achieve a secure connection between the two, one of the first sidewall 130 and the second sidewall 330 is provided with a snap-fit portion 210, and the other is provided with a snap-fit groove 220. Specifically, the snap-fit portion 210 can be provided on the first sidewall 130, and the corresponding snap-fit groove 220 can be provided on the second sidewall 330. Alternatively, depending on the actual design requirements, the snap-fit portion 210 can be provided on the second sidewall 330, and the snap-fit groove 220 can be provided on the first sidewall 130.
[0073] like Figure 4 As shown, the snap-fit portion 210 can be disposed on the first sidewall 130, and the corresponding snap-fit groove 220 is disposed on the second sidewall 330. In this embodiment, the snap-fit portion 210 is specifically disposed on the elastic structure at the end of the first sidewall 130, with one end connected to the first sidewall 130 and the other end extending toward the second sidewall 330. The second sidewall 330 has an inclined guide slope on the side near the first sidewall 130 to ensure that the second U-shaped structure is quickly embedded into the inner cavity of the first U-shaped structure during assembly, and to guide the snap-fit portion 210 smoothly into the snap-fit groove 220, thereby realizing a quick and stable connection between the lampshade 100 and the bracket 300.
[0074] like Figure 5As shown, in this embodiment, the snap-fit portion 210 is disposed on the second sidewall 330, and the corresponding snap-fit groove 220 is disposed on the first sidewall 130. The snap-fit portions 210 are arranged at intervals along the thickness direction of the ambient light 10, and there are multiple snap-fit portions 210; correspondingly, there are also multiple snap-fit grooves 220, which cooperate one-to-one with each snap-fit portion 210. Based on the above structural design, in the assembled state, the snap-fit portions 210 and the snap-fit grooves 220 form a mutually cooperating snap-fit structure, exhibiting a sawtooth-like connection shape, thereby significantly improving the connection strength and assembly stability between the lampshade 100 and the bracket 300, and effectively enhancing the overall structural robustness and deformation resistance.
[0075] Referring to the above, a snap-fit structure can also be used to achieve a fixed connection between the light guide 500 and the bracket 300. That is, corresponding snap-fit and slot structures are provided at the mating positions of the light guide 500 and the bracket 300, respectively. By inserting the snap-fit into the slot and locking it after elastic deformation, quick assembly and stable positioning between the light guide 500 and the bracket 300 can be achieved.
[0076] Additionally, please see Figure 7 The ambient light 10 provided by this utility model is suitable for various vehicle interior lighting scenarios and can be specifically installed on the dashboard (i.e., Figure 7 Position B in the center (to create a simple yet technologically advanced cabin atmosphere); located on the door panel (i.e. Figure 7 Position C in the center of the vehicle can be used to enhance the sense of layering and luxury in the interior space; it can also be installed in the headliner (i.e., Figure 7 Location A in the center is used to provide soft overhead lighting and enhance the visual extension of the overall space.
[0077] The manufacturing process and technology of the lampshade 100 provided in this embodiment of the utility model are as follows: Thermoplastic material is heated to a molten state and fed into an extruder. Under the pushing and shearing action of the screw, the material is uniformly plasticized and then enters a specially designed die through a metering section. The die's cross-section is designed to match the structural dimensions of the lampshade 100, thus extruding the molten material to form a continuous lampshade 100. Subsequently, the profile enters a cooling and shaping device, where it is rapidly solidified using methods such as water cooling or air cooling to maintain its shape stability. Finally, after processes such as traction and length cutting, the desired length of the finished lampshade 100 is obtained.
[0078] The working principle and process of the ambient light 10 provided in this embodiment of the utility model are as follows: Light emitted from the light source is guided into the light guide 500 from one or more ends. The light guide 500 is made of a material with good light transmittance and has efficient light transmission capability. The light propagates along its length inside the light guide 500 and is regulated by the synergistic action of the reflector 510 and the light emitter 530, so that the light is uniformly guided to the entire area of the lampshade 100.
[0079] Meanwhile, the bracket 300 is a non-transparent structure made of opaque material, which effectively prevents light leakage from non-light-emitting directions, avoids stray light interference, further improves the directionality of light emission and the uniformity of lighting effect, and ensures that light is emitted to the outside only through the lampshade 100. The outer surface of the lampshade 100 is provided with a light-transmitting protrusion 111, which extends along the length of the ambient light 10, so that the light is more evenly distributed and emitted inside the lampshade 100, effectively avoiding the appearance of local bright spots or dark areas, thereby achieving a soft, stable lighting experience with good visual effects.
[0080] In summary, this utility model embodiment provides an ambient light 10, which includes a lampshade 100, a bracket 300, and a light guide 500. The bracket 300 is connected to the lampshade 100 and together with the lampshade 100 forms a receiving cavity 400. The light guide 500 is disposed within the receiving cavity 400 to receive light from a light source and guide and distribute the light, thereby achieving a soft and uniform lighting effect. Based on the above, the lampshade 100 is an extruded structure, integrally and continuously formed using an extrusion process, avoiding seam problems caused by splicing, thus significantly improving the overall appearance consistency of the lampshade 100. That is to say, the lampshade 100 formed by the extrusion process has the technical advantage of being ultra-long and seamless. Therefore, along the length of the ambient light 10, the cross-section of the lampshade 100 is the same at any position, which helps the light to propagate and emit uniformly within the lampshade 100, improving the stability of the overall light emission effect and enhancing optical performance.
[0081] 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.
