When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The present invention aims to solve the problems of existing atmosphere lamps in that the metal texture is insufficient, the lighting effect is single and cannot meet personalized needs, and to provide an atmosphere lampshade to achieve a transparent and deep texture on the surface while presenting a metallic luxury and a soft and delicate lighting effect.

[0036] See also Figures 1 to 3 In one embodiment of the present invention, the atmosphere lampshade includes a transparent shell layer 100, a light diffusion shell layer 200 and a decorative film 300, the decorative film 300 includes a substrate layer 303 and an imitation metal layer 301 stacked on the substrate layer 303, and the imitation metal layer 301 presents a metallic texture; the decorative film 300 is arranged between the transparent shell layer 100 and the light diffusion shell layer 200.

[0037] The imitation metal layer 301 presents a metallic texture. In one embodiment, the surface of the decorative film 300 is provided with a PVD coating; the decorative film 300 is provided between the transparent shell 100 and the light diffusion shell 200. In other embodiments, the surface of the decorative film 300 is provided with a CVD coating.

[0038] In addition, the transparent shell layer 100 and the light diffusion shell layer 200 can be connected by means of snap connection or screw connection, or can be integrated by injection molding, which has stronger integrity, higher processing efficiency and better texture.

[0039] Reference Figure 3Specifically, in order to improve the surface texture and visual effect of the atmosphere lampshade, a PVD (physical vapor deposition) coating is provided on the surface of the decorative film 300. This coating technology is often used to enhance the surface hardness and wear resistance of the film, but it can also give the decorative film 300 a unique gloss and color effect, making the decorative film 300 have a metallic texture and a sense of luxury, making the atmosphere lamp more attractive in appearance, and meeting the demand for high-quality materials in modern vehicle interiors. In addition, the PVD coating can also achieve a variety of colors and texture effects, thereby satisfying consumers' pursuit of personalized appearance.

[0040] The decorative film 300 is arranged between the transparent shell 100 and the light diffusion shell 200, and the three are integrated by injection molding process, which can ensure the close fit between the lamp shell and the film, reduce light leakage, and improve the utilization rate of light. When the light passes through the decorative film 300, it can produce a softer and more delicate light effect, avoiding the glare or uneven light problems that may occur in traditional atmosphere lights. At the same time, due to the presence of the decorative film 300, the light will be refracted and reflected during the penetration process, further enriching the lighting effect, so that the atmosphere light can present a more dynamic and changeable light and shadow effect.

[0041] The one-piece injection molding process forms a strong bond between the transparent shell 100, the decorative film 300 and the light diffusion shell 200, improving the structural stability and durability of the entire ambient light. Since the PVD coating can be customized with a variety of colors and texture effects, the ambient light can easily meet consumers' needs for personalized appearance. In addition, by adjusting parameters such as light color and brightness, consumers can also customize the lighting effects of the ambient light according to their preferences and scene requirements, further enhancing the driving experience.

[0042] The technical solution of the present invention is to embed the decorative film 300 between the transparent shell 100 and the light diffusion shell 200 through in-mold injection molding. The decorative film 300 is provided with a metal-like imitation metal layer 301 showing a metallic texture. The plastic material of the transparent shell 100 is matched with the metal-like imitation metal layer 301 showing a metallic texture, so that the metallic texture of the decorative film 300 is significantly enhanced, and the overall surface is transparent and deep, so that the atmosphere light can also reflect the metallic luxury when it is not lit. The light diffusion shell 200 is combined with the transparent shell 100. After lighting, the light is soft and delicate, with a gradient effect, which greatly improves the visual effect. In this way, by using the decorative film 300 with a metallic texture, a texture similar to the metallic texture is made to replace the metal stamping parts in similar products; compared with the direct PVD coating or IML film on the shell surface, which may require additional processing steps, such as pretreatment, coating deposition and post-processing, the decorative film 300 is injected as part of the interlayer to simplify the processing flow, reduce the processing steps, and thus reduce production costs. At the same time, the design of injecting the decorative film 300 as an interlayer reduces the number of parts. In contrast, the traditional PVD coating process or IML process requires multiple processing and assembly steps. This solution improves production efficiency.

[0043] Specifically, the transparent shell 100 is made of transparent plastic material, which can clearly display the internal lighting effects and provide protection at the same time. The light diffusion shell 200 is made of light diffusion plastic material, which can effectively diffuse light, making the lighting effect softer and more uniform. The transparent shell 100 and the light diffusion shell 200 are integrally formed by two-color injection molding technology, which not only ensures the stability of the structure, but also achieves a two-color effect in appearance, increasing the aesthetics. The decorative film 300 is embedded between the transparent shell 100 and the light diffusion shell 200. Through PVD coating, the metallic texture and luxury of the atmosphere lamp can be enhanced; compared with the existing solution to improve the lighting effect by adding a light diffusion plastic lampshade rear shell, this solution integrates the light diffusion shell on the front shell of the atmosphere lampshade, which can reduce the thickness of the atmosphere lampshade and optimize the spatial structure.

[0044] In this way, the ambient lampshade has a metallic texture, a sense of luxury and a two-color effect in appearance. The PVD coating on the surface of the decorative film 300 gives the ambient lamp a unique metallic luster and color effect, making it look more upscale and luxurious. The transparent shell 100 and the light diffusion shell 200 form a sharp contrast in color, which increases the aesthetics and visual effect of the ambient lamp. The transparent shell 100 made of transparent plastic material can clearly display the lighting effect, while the light diffusion shell 200 made of light diffusion plastic material can diffuse the light, making the light softer and more uniform. This combination not only ensures the brightness of the light, but also avoids glare, thereby improving driving comfort.

[0045] The PVD coating layer can be directly connected to the substrate (base material layer 303) without adhesive. In order to make the bonding more stable, the decorative film 300 specifically includes a PVD coating layer, an adhesive layer 302 and a plastic layer arranged in sequence.

[0046] The PVD (physical vapor deposition) coating can give the decorative film 300 a metallic luster and color effect, making it look more upscale and luxurious. The adhesive layer 302 can tightly combine the PVD coating and the plastic layer to prevent delamination or shedding during use. As the base of the decorative film 300, the plastic layer can provide sufficient support and protection to prevent the PVD coating and the adhesive layer 302 from being damaged. The plastic layer has good fluidity and plasticity, which facilitates tight combination with the transparent shell layer 100 and the light diffusion shell layer 200 during the injection molding process.

[0047] Specifically, the thickness of the decorative film sheet 300 ranges from 0.2 mm to 0.5 mm. In one embodiment, the thickness of the decorative film sheet 300 is 0.3 mm. In other embodiments, the thickness of the decorative film sheet 300 is 0.35 mm or 0.4 mm.

[0048] A thinner decorative film 300 can reduce the amount of material used, thereby reducing production costs; and an appropriate thickness range can ensure the transmittance and diffusion effect of the decorative film 300 on light, making the lighting effect softer and more uniform.

[0049] In addition, the thickness of the ambient lamp cover as a whole ranges from 5.6mm to 6mm; thus, under the constraints of extremely small space conditions, the modeling meets the pursuit of static crystal metal texture and dynamic deep and soft with gradient light effect. Moreover, the setting of the overall injection molding thickness can ensure that the ambient light fits closely with the vehicle interior during installation, improving the convenience and stability of installation.

[0050] Furthermore, the ratio of the maximum wall thickness of the transparent shell layer 100 to the maximum wall thickness of the light diffusion shell layer 200 is in the range of 0.8-1.

[0051] In one embodiment, the maximum thickness of the transparent shell 100 is 2.5 mm, and the maximum thickness of the light diffusion shell 200 is 3 mm; in other embodiments, the maximum thickness of the transparent shell 100 and the light diffusion shell 200 are both 3 mm. As a transparent layer, the wall thickness of the transparent shell 100 has a direct impact on the transmittance of light. As a light diffusion layer, the wall thickness of the light diffusion shell 200 affects the diffusion effect of light. The light diffusion shell 200 of appropriate thickness can make the light more evenly distributed on the surface of the lamp shell, avoiding the phenomenon of local over-brightness or over-darkness. By setting the maximum wall thickness ratio of the transparent shell 100 and the light diffusion shell 200 between 0.8 and 1, for example, the thickness of the transparent shell 100 is 2.5 mm, and the thickness of the light diffusion shell 200 is 3 mm, a balance point can be found so that the light can be effectively transmitted and evenly diffused to achieve the best visual effect. By optimizing the wall thickness ratio, plastic materials can be used more effectively. The thicker part can reduce material waste and reduce production costs.

[0052] Furthermore, the ambient lamp cover can be used as an ambient lamp on a vehicle. Specifically, the ambient lamp also includes a light guide 400 and a lamp head harness assembly 500 connected to the light guide 400 . The light guide 400 and the lamp head harness assembly 500 are both arranged on the light diffusion shell 200 .

[0053] Reference Figure 2 Specifically, the light diffusion shell 200 includes a main section 210 and two ribs 220 arranged on the main section 210. The two ribs 220 are arranged at intervals to form a mounting groove 221, and the light guide 400 is embedded in the mounting groove 221. The decorative film 300 is arranged between the main section 210 and the transparent shell 100. The light guide 400, as a medium for light transmission, can guide the light to propagate along a specific path. By embedding the light guide 400 in the mounting groove 221 of the light diffusion shell 200, it can be ensured that the light is diffused in a predetermined manner to form a specific lighting effect. The introduction of the light guide 400 enables the ambient light to present more complex and varied lighting patterns and dynamic effects, thereby enhancing the interior visual effects and driving experience of the vehicle. The combination of the light guide 400 and the lamp head harness assembly 500 enables the lighting effects of the ambient light to be adjusted and customized as needed. By changing the shape, length and layout of the light guide 400 and adjusting parameters such as the current and voltage of the lamp holder harness assembly 500, a variety of different lighting effects can be achieved to meet the personalized needs of consumers.

[0054] The two ribs 220 arranged on the main section 210 of the light diffusion shell 200 are spaced apart to form a mounting groove 221, which provides a stable support for the light guide 400. The design of the ribs 220 can prevent the light guide 400 from being deformed or shifted during installation and use, ensuring the stability and consistency of the lighting effect. The existence of the ribs 220 also makes the installation of the light guide 400 more convenient and reliable. During installation, the light guide 400 only needs to be embedded in the mounting groove 221, which reduces the difficulty and cost of installation.

[0055] Specifically, the rib 220 extends in a direction away from the main section 210, and the extension length of the rib 220 is greater than the wall thickness of the main section 210. The extension length of the rib 220 is greater than the wall thickness of the main section 210, which means that the side wall of the mounting groove 221 is additionally reinforced. This helps to maintain the shape and dimensional stability of the mounting groove 221, ensuring that the light guide 400 can be tightly and stably embedded in the mounting groove 221 to avoid loosening or displacement during use. The rib 220 extends in a direction away from the main section 210, forming a structure similar to a reinforcing rib, which can enhance the overall support force of the light diffusion shell 200 and make it more sturdy and durable. The design of the rib 220 makes the opening of the mounting groove 221 more spacious, which is convenient for the installation and positioning of the light guide 400. During the installation process, the light guide 400 can be more easily inserted into the mounting groove 221 and its position can be adjusted to achieve the best lighting effect. In addition, the ribs 220 can also provide a certain limit function for the light guide 400 to prevent it from sliding or deflecting during the installation process.

[0056] Furthermore, the method for making the atmosphere lampshade comprises the following steps:

[0057] A decorative film 300 with a PVD coating is provided or prepared; the decorative film 300 is sent into a PVD device to form a uniform coating on the surface of the film by physical vapor deposition technology. The coating can be made of metal, alloy, ceramic and other materials, and is selected according to the required color and performance.

[0058] Injection molding the transparent shell layer 100 in the first molding cavity of the two-color mold; specifically, the process includes the following steps:

[0059] Mold preparation, a two-color mold is usually composed of two independent molding cavities, which are used to respectively inject the transparent shell layer 100 and the light diffusion shell layer 200. Before injection molding, ensure that the mold is clean and at a suitable temperature to avoid injection molding defects.

[0060] The injection molding material is selected according to the performance requirements of the transparent shell layer 100 (such as strength, heat resistance, corrosion resistance, etc.).

[0061] In the injection molding process, the injection molding material is heated to a molten state and then injected into the first molding cavity of the two-color mold. The injection molding pressure and speed are controlled to ensure the quality and dimensional accuracy of the transparent shell layer 100.

[0062] Before the transparent shell 100 cools down but is not completely solidified, the decorative film 300 is positioned on the two-color mold; before the transparent shell 100 cools down but is not completely solidified, the decorative film 300 is quickly positioned at a predetermined position of the two-color mold. Use a positioning device or fixture in the mold to ensure that the positional relationship between the decorative film 300 and the transparent shell 100 is accurate.

[0063] After ensuring that the decorative film 300 has been firmly embedded in the transparent shell 100, the mold is switched to inject the light diffusion shell 200 in the second molding cavity of the two-color mold; mold switching, when the decorative film 300 is firmly embedded in the transparent shell 100, the mold is switched to make the second molding cavity face the transparent shell 100. Injection molding of the light diffusion shell 200, the same or different injection molding material as the material of the transparent shell 100 is injected into the second molding cavity. Control the injection molding pressure and speed to ensure that the light diffusion shell 200 is tightly bonded to the transparent shell 100 and of good quality.

[0064] After the injection is completed, the mold is cooled to completely solidify the transparent shell layer 100 and the light diffusion shell layer 200. The cooling time is adjusted according to the type and thickness of the injection material.

[0065] After cooling, demoulding, trimming and inspection are carried out. Specifically, demoulding, when the mold is cooled to a suitable temperature, the mold is opened and the injection-molded atmosphere lampshade is taken out. Trimming, trimming the injection-molded atmosphere lampshade to remove defects such as burrs and flash. Inspection, quality inspection of the trimmed atmosphere lampshade, including inspection of appearance, size, performance, etc. Ensure that the atmosphere lampshade meets the design requirements and quality standards.
