Description

Technical Field

[0001] This utility model relates to the field of optical effects, and in particular to a curved irregular-shaped light-emitting component. Background Technology

[0002] Designs for home appliances, smart homes, consumer electronics, and automotive smart cockpits require a wide variety of innovative design elements. Among these, light is the most direct and immersive element for stimulating the human eye. Therefore, designers pay close attention to the use of lighting effects and the details of light effects during the design process. Delicate and dazzling personalized lighting devices can bring a variety of distinctive experiences to the design, leaving a deep impression on consumers. Lighting design is an indispensable part of the design of all types of products, used to express information, remind users, and enhance the overall effect. Reasonable lighting design can not only add color to cold products but also enhance the user experience, winning consumers' long-term attention and desire for repeat purchases.

[0003] Existing traditional light guide materials can only achieve simple, single backlight applications, and are generally mainly used for display backlighting of LCD screens or other simple light-emitting and lighting functions;

[0004] Structurally, traditional light guide materials are mostly made of single transparent plastic or glass, and their light guiding forms are relatively simple, making it difficult to achieve light transmission on complex curved surfaces. This results in the light-emitting effect being limited to flat or regular shapes, which cannot meet the diverse needs of modern product design for curved and irregular light-emitting effects.

[0005] In terms of surface treatment, traditional light guide materials usually lack effective functional coatings or structural optimizations, which makes it easy for light to scatter, be lost, or be locally too bright / too dark during transmission, further limiting the uniformity of light effect and visual performance.

[0006] Therefore, it is necessary to provide a new curved irregular-shaped light-emitting component to solve the above-mentioned technical problems. Utility Model Content

[0027] Compared with related technologies, the curved irregular-shaped light-emitting component provided by this utility model has the following beneficial effects:

[0028] This invention breaks through the limitations of traditional light guide materials, which are mostly single transparent plastic or glass, with limited light guiding forms and difficulty in achieving light transmission on complex curved surfaces, by setting a transparent light guide.

[0056] A mold is fixed to the bottom wall of the box 3. The mold includes a first female mold 36 and a first male mold 38.

[0057] The mold also includes a second female mold 361 and a second male mold 381. Both the second female mold 361 and the second male mold 381 are fixedly connected to the inner wall of the box 3, and the second female mold 361 is located directly below the second male mold 381.

[0058] The top of the platform body 1 is provided with a placement area 13 for placing a transparent light guide 5. The top of the platform body 1 is also provided with a plurality of first positioning holes 14, which are located opposite to each other on the outside of the placement area 13.

[0059] The clamping assembly includes multiple limiting plates 51, one side of which is attached to the outer side of the transparent light guide 5.

[0060] An operating table 11 is fixed on one side of the platform body 1. A display screen 12 is also mounted on the surface of the operating table 11. A mounting frame 2 is also placed on one side of the platform body 1, and a robotic arm 21 is fixed on the top of the mounting frame 2.

[0061] The coating assembly includes a mounting plate 22, the top of which is fixedly connected to the output end of the robotic arm 21. A roller 23 is rotatably mounted on the inner wall of the mounting plate 22, and a metal mold core 24 is attached to the surface of the roller 23.

[0062] Working principle: In use, the transparent light guide 5 is first placed in the placement area 13 on the top of the platform body 1. Multiple limiting plates 51 limit the transparent light guide 5 from different directions, making its outer side fit against the limiting plates 51. Then, the screw 53 passes through the first positioning hole 14 and the second positioning hole 52 in sequence and is tightened. The limiting plates 51 are fixed to the platform body 1 by the threaded connection, thereby achieving stable clamping of the transparent light guide 5. Soft rubber pads are provided at the edges of the limiting plates 51 and the transparent light guide 5 to avoid damage caused by clamping. The robotic arm 21 on the top of the mounting frame 2 is activated, driving the mounting plate 22 at its output end to move, so that the roller 23 rotating on the inner wall of the mounting plate 22 contacts the surface of the transparent light guide 5. Nano paste is filled onto the surface of the transparent light guide 5 by manual operation or pressing equipment to form a nano paste layer 63. At this time, the transparent light guide 5 filled with the nano paste layer 63 is placed into the mold in the box 3. The mold includes a first The female mold 36, the first male mold 38, the second female mold 361, and the second male mold 381 can achieve different molding of the transparent light guide 37. The cover plate 4 is covered and fastened to the top of the cover plate 4 by the elastic clamping plate 41. The elastic clamping plate 11, such as a rubber clamping block, and the sealing ring are used to ensure the airtightness of the box 3. At this time, the heating module 34 is started and obtains electrical energy through the wire 35 to connect with the external device to heat the inside of the box 3. The external device, such as a battery, and the temperature sensor 33 monitor the temperature inside the box 3. This is existing technology and will not be described here. At the same time, the gas booster pump 31 is started and delivers gas to the jet pipe 39 through the supply pipe 311. The gas is ejected from the jet hole 391 and pressurizes the transparent light guide 37 inside the box 3. Under the combined action of heating and pressurization, the thermoplastic pressure molding of the transparent light guide 37 is completed. After the transparent light guide 37 is formed, the LED light strip is equipped on the light-incident side of the transparent light guide 5 to complete the assembly of the entire curved irregular light-emitting component.

[0063] Furthermore, molding is performed using the first female mold 36 and the first male mold 38, including the following steps:

[0064] I. Preparation Stage: After placing and clamping the transparent light guide 5, the robotic arm 21 uniformly coats the surface of the transparent light guide 5 with a nano-slurry layer 63, and then places the processed transparent light guide 5 into the cavity of the first negative mold 36 inside the housing 3. The first negative mold 36 is fixed to the bottom wall of the housing 3, and its cavity shape is designed according to the curved irregular structure of the part to be formed by the transparent light guide 37.

[0065] 2. Mold Closing Stage: Start the gas booster pump 31 of the equipment to make the first male mold 38 move downward under the action of driving force. The first male mold 38 and the first female mold 36 are set opposite to each other and aligned. As the first male mold 38 descends, it gradually approaches the first female mold 36 and finally completely closes with the first female mold 36, sandwiching the transparent light guide 5 between the two to form a closed molding space.

[0066] III. Heating and Pressurization Stage: After the mold closing stage is completed, the heating module 34 starts working, connecting to external equipment via wire 35 to obtain electrical energy and generate heat. The heat is transferred to the interior of the housing 3, raising the temperature within the molding space. Simultaneously, the gas booster pump 31 continues to pressurize, compressing the external gas and delivering it to the jet pipe 39 via the supply pipe 311. The gas is ejected from the jet hole 391, applying pressure to the transparent light guide 5 within the molding space. Under the combined action of heating and pressurization, the transparent light guide 5, along with its surface metal core sheet 24 and nano-slurry layer 63, undergoes thermoplastic deformation, gradually filling the mold cavity shape formed by the first female mold 36 and the first male mold 38.

[0067] IV. Pressure Holding and Cooling Stage: After the preset heating time and pressure value are reached, the heating module 34 stops heating, but the gas booster pump 31 continues to maintain a certain pressure, keeping the transparent light guide 37 in a pressure holding state within the mold cavity for a period of time to ensure its full molding and shaping. Subsequently, the transparent light guide 37 cools and solidifies through natural cooling.

[0068] V. Mold Opening and Part Removal Stage: After cooling is complete, open the cover plate 4, move the first male mold 38 upward and remove it, separating it from the first female mold 36. Open the mold, and then the operator removes the formed transparent light guide 37 from the cavity of the first female mold 36, completing the forming process using the first female mold 36 and the first male mold 38.

[0069] Furthermore, the process involves forming using a second female mold 361 and a second male mold 381. The specific operation method is the same as that of forming with the first female mold 36 and the first male mold 38. The difference lies in the shape of the transparent light guide 37 after forming with the second female mold 361 and the second male mold 381. Following this method:

[0070] For reference Figure 1 , Figure 2 , Figure 6 , Figure 7 as well as Figure 9 As shown, the surface of the transparent light guide 37 is recessed inward to form a bowl shape 6.

[0071] Specifically, regarding the bowl-shaped recessed structure: when light enters the transparent light guide 37, it encounters the bowl-shaped recessed structure during propagation. Due to the special shape of the bowl-shaped structure, the light will undergo multiple reflections and refractions on the inner surface of the recess. Some of the light will be reflected back into the transparent light guide 37 to continue propagating, changing its original propagation direction; another part of the light will be refracted and emitted from a specific direction on the surface of the transparent light guide 37, thereby achieving the redistribution and guidance of the light, so that the light can be more evenly distributed in the area that needs illumination, or emitted according to a specific pattern and angle to meet different lighting needs.

[0072] For reference Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 8 As shown, the surface of the transparent light guide 37 is recessed inward to form a concave shape 61.

[0073] Specifically, regarding the concave structure: when light propagates within the transparent light guide 37 to the concave structure 61, the shallow concave shape of the concave structure causes a certain degree of scattering and reflection of the light. This scattering and reflection can disrupt the uniformity of light propagation within the transparent light guide 37, causing variations in the light in localized areas. This results in alternating light and dark or textured lighting effects on the surface of the transparent light guide 37, increasing the sense of depth and visual impact of the illumination.

[0074] For reference Figure 10 As shown, the surface of the transparent light guide 37 is recessed inward to form a cone shape 62.

[0075] Specifically, for the conical recessed structure: when light propagates to the conical recessed structure, the geometry of the conical structure determines the laws of light reflection and refraction. Light will undergo total internal reflection or refraction on the inner surface of the conical structure. Total internal reflection will cause the light to reflect multiple times inside the conical structure, enhancing the propagation distance and intensity of the light; while refraction will cause the light to change its propagation direction and exit from the surface of the transparent light guide 37 at a specific angle, achieving specific optical effects, such as focusing and scattering light.

[0076] Furthermore, the thickness of the transparent light guide 5, which is bowl-shaped 6, concave 61, and conical 62, is between 0.05mm and 8mm.

[0077] In some embodiments, reference is made to Figures 11 to 15 As shown in the figure, the concave 6 and the bowl-shaped 61 are both transparent light guides 37, and the nano-slurry layer 63 forms a micro-nano structure on the surface of the transparent light guide 5.

[0078] in, Figure 11 This is a schematic diagram of the micro / nano structure on the outer surface of the recessed cavity; Figure 12 This is a schematic diagram of the micro / nano structure on the inner surface of the recessed cavity; Figure 13 This is a schematic diagram of the micro / nano structure on the outer surface of the arc-shaped cavity.

[0079] Figure 14 This is a schematic diagram of the micro / nano structure on the inner surface of an arc-shaped cavity; Figure 15 A schematic diagram of a structure filled with nano-slurry; during filling, Figure 15The top is a mold, the middle is a nano-slurry filling layer 63, and the bottom is a transparent light guide 37. The shape is achieved by pressing, including manual pressing and mechanical pressing. The pressing method is existing technology and will not be described here.

[0080] In some embodiments, reference is made to Figures 1 to 15 As shown, another method for manufacturing an irregularly shaped curved surface light-emitting component further includes the following steps:

[0081] Step S1: Provide a micro / nano imprinting process system and basic materials.

[0082] The micro-nano imprinting process system includes an imprinting platform and a flexible steel plate mold with raised micro-nano structures machined by laser lithography or diamond cutting tools, or a nickel plate obtained by electroforming copying technology, which is covered by the pressure rollers of the imprinting platform. The thickness of the steel plate or nickel plate mold is between 0.1-0.5mm. The base material includes optical-grade high-transparency materials such as PC, PMMA, PS, and MS, with a thickness between 0.05mm-8mm. The base material can be roll or sheet, and can be flat and smooth on one side and have other morphological microstructures on the other side.

[0083] The original mold for the steel plate or nickel plate mold has a mirror surface roughness of less than or equal to Ra2.0.

[0084] Step S2: Place the base material on the embossing processing platform.

[0085] Step S3: Use a flexible steel plate mold with pre-processed protruding micro-nano structures or a nickel plate mold obtained by electroforming flipping technology to cover the pressure roller of the embossing platform.

[0086] Step S4: Start the heating system of the imprinting platform, set the temperature of the pressure roller and heat it to the imprinting temperature required for different base materials, and start the pressure system of the imprinting platform.

[0087] Step S5: The base material is brought into contact with the pressure roller line of the mold and moved forward. After being subjected to temperature and pressure, a base material with a concave microstructure is obtained. Multiple protrusions corresponding to multiple concave surfaces on the surface of the base material are processed on the surface of the mold.

[0088] Step S6: Provide a coating platform and prepare a base material with recessed optical microstructures.

[0089] Coating platforms include, but are not limited to, roller coating and flat-plate scraping platforms. This utility model mainly introduces a slotted die-scraping flat-plate platform for preparing base materials with recessed microstructures filled with nano-metals. The platform includes a nano-slurry drip tank, a fluid flow control pump, a scraping die, and a high-temperature sintering and baking channel or a UV curing channel. Two different curing methods are employed based on the different physical and chemical properties of the nano-slurries.

[0090] Step S7: Test and match pump drip irrigation parameters, adjust the angle of the coating mold and the gap with the base material with recessed optical microstructure, start the coating platform drip irrigation system, set the rotation speed of the horizontal conveyor belt of the coating platform, and after the base material with recessed optical microstructure passes through the coating mold and is cured, a composite light guide material with surface recessed optical microstructure filled with nano paste is obtained.

[0091] Step S8: Provide a hot pressing molding platform and pre-made composite light guide material.

[0092] Hot pressing platforms include, but are not limited to, high-pressure forming and vacuum forming platforms. This utility model mainly introduces the use of a high-pressure forming platform to produce irregularly shaped curved light guide materials. The platform includes a high-pressure gas supply system, a mold and cavity heating system, and a hydraulic motion system. Depending on the characteristics of different curved components, two mold combination forms are used: a single master mold or a male-female combined mold.

[0093] The practical benefits include: by using high-temperature resistant nano-slurry deposition to fill the surface depressions of the base material with optical microstructures, a composite light guide material with a surface optical microstructure that can withstand temperatures from 120°C to 300°C can be obtained. Further combined with high-pressure molding processes, this can meet the ultra-thin, integrated, irregularly shaped curved surface light-emitting and lighting needs in various application scenarios such as automotive smart cockpits, home appliances, consumer electronics, and architecture. The future market application prospects are very broad, bringing significant economic and social benefits.

[0094] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0095] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
