Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a festive decorative lamp and its preparation method. Background Technology

[0002] In existing technologies, the production of polymer clay (bread clay) luminous products mainly relies on two processes: First, an inner mold made of plastic or rubber is typically used as the base, with the polymer clay wrapped around it. After baking and shaping, the luminous components are then glued together. This method suffers from limitations in the shape of the inner mold, high cost, gaps between the light source and the polymer clay affecting light transmission and color performance, and problems such as glue overflow, whitening, or sticking during switching are common, leading to a higher product defect rate. Second, after the polymer clay has set, the luminous components are attached externally by binding or wrapping. However, this method easily leads to tangling and damage to the light wires, and the light source is too concentrated and glaring, detracting from the aesthetic appeal of the polymer clay itself. Therefore, existing technologies have significant shortcomings in terms of production cost, light transmission effect, product reliability, and aesthetics. To address these issues, this paper proposes a festive decorative light and its preparation method. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides a festive decorative light, comprising: A one-piece molded polymer clay body, wherein the polymer clay body has mounting holes along the axial direction; The light-emitting component includes a lamp wire disposed along the axial direction in the mounting hole, and a light source disposed on the lamp wire. The light source is electrically connected to an external power supply through the lamp wire, and when powered on, the light emitted by the light source is transmitted outward through the polymer clay body surrounding it. A soft light layer is wrapped around the outside of the light source to weaken the intensity of the light emitted by the light source. The soft light layer is made of a transparent material.

[0004] Optionally, it also includes a reinforcing cover disposed on the polymer clay body, and the center of the reinforcing cover is provided with a through hole along the axial direction, the axial direction of the through hole is consistent with the radial direction of the lamp wire, at least a portion of the light source is disposed in the through hole, the inner cavity of the reinforcing cover has a funnel-shaped structure, and the opening size at the end closer to the lamp wire is smaller than the opening size at the end farther away, so as to enhance the light emitted by the weakened light source.

[0005] Optionally, the polymer clay body is recessed into a mounting groove in the radial direction of the mounting hole from the hole wall of the mounting hole, and the reinforcing cover is fixedly disposed in the mounting groove.

[0006] Optionally, it also includes a sealing element and a threaded hole. The threaded hole is provided on the wall of the mounting hole in the axial direction from the opening of the mounting hole inward. The outer wall of the sealing element is provided with a first external thread so that the sealing element is threadedly installed in the threaded hole through the cooperation of the first external thread with the threaded hole, so as to seal the opening of the mounting hole through the sealing element. The lamp wire passes through the sealing element and is connected to the external power supply.

[0007] Optionally, the sealing element includes a first tube and a T-shaped plate; At least a portion of the first tube is disposed within the mounting hole, the first external thread is disposed on the outer side wall of the first tube, and the inner side wall of the first tube is provided with an internal thread along the axial direction. The transverse section of the T-shaped plate is coaxially arranged with the first tube, and a second external thread is provided on the circumferential wall of the transverse section of the T-shaped plate along the axial direction. Through the cooperation of the second external thread and the internal thread, the transverse section of the T-shaped plate is threadedly inserted into the first tube. The vertical section of the T-shaped plate is used to block the opening of the first tube located outside the mounting hole. The lamp wire is rotatably arranged on the T-shaped plate along the axial direction. By adjusting the depth of the transverse section of the T-shaped plate in the first tube, the relative position of the light source in the polymer clay body can be adjusted by the lamp wire. The light source is movable inside the reinforcing cover.

[0008] Optionally, the number of light sources is set to several, and the several light sources are arranged at equal intervals along the axial direction of the lamp line.

[0009] Optionally, the polymer clay body is provided with a connecting hole and several light guide channels. The connecting hole is connected to the mounting hole, and the end of the connecting hole near the mounting hole faces the light source to guide the light emitted by the light source into the connecting hole. The light inlets of the several light guide channels are all connected to the end of the connecting hole away from the mounting hole, and the light emitting ends are distributed all over the periphery of the polymer clay body to achieve multi-point light emission.

[0010] To achieve the above objectives, the present invention also provides a method for preparing a festive decorative light, comprising the following steps: S1: Provide a malleable polymer clay blank and a light-emitting component, the light-emitting component including a lamp wire and at least one light source disposed on the lamp wire; S2: Wrap the polymer clay blank around the light-emitting component, so that the light source is embedded and fixed in the polymer clay blank to form a green body; S3: Place the entire green body in an oven and bake it at a constant temperature of 130°C to 140°C for 20 to 40 minutes to solidify and shape the polymer clay body. S4: After the baked product is cooled to below 60°C, it is taken out to obtain a polymer clay luminescent product with the luminescent component integrated inside.

[0011] Optionally, in step S2, the polymer clay blank is wrapped around the light-emitting component using a molding method: the light-emitting component is placed in the cavity of an inner mold, then the polymer clay blank is filled into the cavity and covers the light-emitting component, and finally the mold is demolded to form the green blank.

[0012] Optionally, in step S2, the polymer clay blank is wrapped around the light-emitting component by manual molding: the polymer clay blank is directly shaped and wrapped around the outside of the light-emitting component.

[0013] The beneficial effects of this invention are as follows: This invention effectively overcomes the shortcomings of existing technologies by adopting a one-piece molded polymer clay body with axially opened mounting holes to directly accommodate the light-emitting components. This design eliminates the expensive and shape-restricting inner mold in traditional processes, simplifies production steps, and significantly reduces costs. At the same time, the light emitted by the light source is directly and evenly transmitted through the surrounding polymer clay body, avoiding problems such as light obstruction, gaps, and whitening of glue marks caused by glue bonding or external wrapping. This achieves excellent light-emitting effects with soft light, pure color, and strong product integrity, while greatly improving the production reliability and visual aesthetics of the product.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but do not exclude other elements or objects.

[0017] To address the problems existing in the prior art, embodiments of the present invention provide a festive decorative light, such as... Figure 1 and Figure 2 As shown, it includes a polymer clay body 1, a light-emitting component, and a soft, low-light layer 5.

[0018] In one embodiment, such as Figure 2 As shown, the polymer clay body 1 is integrally molded, and the polymer clay body 1 has mounting holes 2 along the axial direction. Designing the polymer clay body 1 as an integrally molded structure with mounting holes 2 along the axial direction offers several significant advantages. Firstly, this design fundamentally simplifies the production process, eliminating the need for an inner mold and subsequent glue bonding required in traditional methods. This not only reduces manufacturing costs but also avoids quality issues such as glue overflow and whitening that may occur with glue. Secondly, the integrally molded structure ensures the product's integrity and structural strength, while the axial mounting holes 2 provide a precise and stable positioning channel for the light-emitting components. This allows the light source 4 to be neatly placed in a preset position, and the emitted light can directly and evenly diffuse outwards through the surrounding polymer clay material. This effectively eliminates the uneven light transmission or light efficiency loss caused by gaps between the light source 4 and the polymer clay body in traditional processes, thus achieving a softer light and better visual integration.

[0019] In one embodiment, such as Figure 2As shown, the light-emitting component includes a lamp wire 3 arranged axially within the mounting hole 2, and a light source 4 disposed on the lamp wire 3. The light source 4 is electrically connected to an external power supply through the lamp wire 3, and when powered on, the light emitted by the light source 4 is transmitted outward through the surrounding polymer clay body 1. This embodiment sets the light-emitting component to include a lamp wire 3 arranged axially within the mounting hole 2 and a light source 4 on the wire, and connects to an external power supply through the lamp wire 3. This structural arrangement brings key technical advantages. This design first ensures that the light-emitting component can be stably and accurately positioned inside the polymer clay body 1, and that the light source 4 and the polymer clay material form a tight, gapless contact, so that when powered on, the light can be efficiently guided and evenly diffused outward through the surrounding polymer clay body 1, effectively avoiding the light blocking, uneven scattering, or glare problems caused by traditional external bonding or wrapping methods. Secondly, this built-in integrated electrical connection method not only simplifies the assembly process and improves production efficiency, but also significantly enhances the reliability and safety of the product, avoiding the risks of damage and tangling of external wires, and ultimately achieving excellent light-emitting effects with soft light, visual unity and durable structure.

[0020] In one embodiment, such as Figure 2 As shown, the soft light-low layer 5 covers the outside of the light source 4 to weaken the intensity of the light emitted by the light source 4. The soft light-low layer 5 is made of transparent material. This embodiment sets up a soft light-low layer 5 made of transparent material and covers the outside of the light source 4. This structure innovatively solves the technical problem of high brightness and glare from point LED light sources 4. This transparent soft light-low layer can effectively filter and scatter the original strong light emitted by the light source 4, transforming the concentrated point light source 4 into a uniform and soft surface light source 4 without significantly affecting the luminous flux, thus completely eliminating glare. This not only greatly improves the visual comfort and aesthetics of the product, allowing the light to better highlight the texture and color of the polymer clay body 1, but also overcomes the defect of traditional decorative lights that are difficult to view up close for a long time due to harsh light, ultimately achieving a high degree of unity between aesthetics and practicality.

[0021] In one embodiment, the material of the soft light-diffusing layer 5 can be optical-grade silicone, transparent soft PVC, or flexible optical diffusion resin. These materials not only possess excellent light transmittance and flexibility, allowing them to closely adhere to the surface of the light source 4, but also efficiently convert the direct, intense light from the point light source 4 into uniform, soft diffused light through their internal light-scattering particles or microstructures. Using such materials ensures that the soft light layer remains stable during high-temperature baking and will not adversely react with the polymer clay body 1 or the light source 4, thus achieving the core function of light softening while guaranteeing the feasibility of the product manufacturing process and the reliability of long-term use.

[0022] In one embodiment, such as Figure 2As shown, the festive decorative light also includes a reinforcing cover 6 disposed on the polymer clay body 1, and the reinforcing cover 6 has a through hole in the middle along the axial direction. The axial direction of the through hole is consistent with the radial direction of the light wire 3. At least a portion of the light source 4 is disposed in the through hole. The inner cavity of the reinforcing cover 6 has a trumpet-shaped structure, and the opening size at the end closer to the light wire 3 is smaller than the opening size at the end farther away, so as to enhance the light emitted by the weakened light source 4.

[0023] This embodiment adds a reinforcing cover 6 with a specific flared inner cavity, a structural design that brings a key optical enhancement effect. Its flared structure, with a smaller opening near the light wire 3 and a larger opening further away, effectively collects and converges the diffused light emitted from the light source 4, which has been softened by the dimming layer. Like a built-in concentrator, it directs the light to cover a wider area of ​​the polymer clay body 1. This not only compensates for the potential brightness loss due to light softening, ensuring overall luminous intensity, but more importantly, it makes the light output more directional and layered, further improving the uniformity and three-dimensionality of the illumination. Thus, while maintaining soft, non-glaring visual comfort, it significantly enhances the fullness and artistic expression of the final luminous effect.

[0024] In one embodiment, the reinforcing cover 6 can be made of a high-reflectivity metal, such as anodized aluminum or silver-plated copper alloy, or an engineering plastic with excellent light reflection properties, such as PC (polycarbonate) or PMMA (acrylic) coated with a metal reflective film. Using such a high-reflectivity material ensures that the trumpet-shaped inner surface of the reinforcing cover 6 forms efficient total internal reflection or specular reflection of light, minimizing light energy absorption loss and concentrating and precisely guiding the light emitted by the light source 4 in a preset direction. This not only significantly improves the utilization rate and light emission efficiency, making the luminous effect of the polymer clay body 1 brighter and fuller, but also allows for precise light control to shape specific light and shadow contours, further enhancing the product's luminous layering and artistic expression.

[0025] In one embodiment, such as Figure 2As shown, in the radial direction of the lamp wire 3, the polymer clay body 1 has a recessed mounting groove 7 formed from the wall of the mounting hole 2 in a direction away from the light source 3. The reinforcing cover 6 is fixedly installed in the mounting groove 7. The mounting groove 7 provided in this embodiment provides a precise and stable positioning and mounting base for the reinforcing cover 6, ensuring that the trumpet-shaped through hole of the reinforcing cover 6 can always maintain a precise alignment with the light source 4 in the mounting hole 2, thereby ensuring the stability and consistency of light collection and guiding effects. This embedded installation method not only makes the reinforcing cover 6 and the polymer clay body 1 more flat and firm, improving the overall structural strength and aesthetics of the product and avoiding the risk of component loosening, but also simplifies the assembly process, facilitating fast and accurate assembly during production, and ultimately ensuring the reliability and repeatability of the optical system performance.

[0026] In one embodiment, such as Figure 2 As shown, the festive decorative light also includes a sealing member 8 and a threaded hole. The threaded hole is provided on the wall of the mounting hole 2 from the opening of the mounting hole 2 inward in the axial direction. The outer wall of the sealing member 8 is provided with a first external thread, so that the sealing member 8 is threadedly installed in the threaded hole through the cooperation of the first external thread and the threaded hole, so as to seal the opening of the mounting hole 2 through the sealing member 8. The light wire 3 passes through the sealing member 8 and is connected to the external power supply.

[0027] This embodiment achieves multiple important functions through a structural design that uses a sealing member 8 with a first external thread to mate with a threaded hole on the wall of the mounting hole 2. This threaded connection provides a reliable and removable sealing solution for the opening of the mounting hole 2, effectively preventing external contaminants such as dust and moisture from entering the mounting hole 2, protecting the light-emitting components, and ensuring the cleanliness and safety of the product's internal structure, thus improving the product's environmental adaptability and lifespan. Simultaneously, this design allows the lamp wire 3 to pass orderly through the sealing member 8 and connect to the external power supply, ensuring the stability of the electrical connection while maintaining a clean and uncluttered overall appearance. Furthermore, the removable sealing member 8 facilitates subsequent maintenance or replacement of internal components, demonstrating the practicality and user-friendliness of the product design.

[0028] In one embodiment, such as Figure 2 As shown, the sealing component 8 includes a first tube 81 and a T-shaped plate 82.

[0029] In one embodiment, such as Figure 2As shown, at least a portion of the first tube 81 is disposed within the mounting hole 2, the first external thread is disposed on the outer side wall of the first tube 81, and the inner side wall of the first tube 81 is provided with an internal thread along the axial direction. In this embodiment, the first tube 81 is partially disposed within the mounting hole 2, and a first external thread is provided on its outer side wall and an internal thread is provided on its inner side wall. This nested thread structure forms a multi-stage adjustable precision sealing plugging system. The first tube 81 is firmly connected to the threaded hole on the wall of the mounting hole 2 through its outer first external thread, serving as the basic framework of the entire sealing structure; while its inner internal thread provides a reliable interface for the precise screwing and depth positioning of subsequent internal adjustment components such as the T-shaped plate 82. This design not only achieves a firm seal of the opening of the mounting hole 2, effectively preventing dust and moisture, but more importantly, it constructs a modular, finely adjustable assembly platform, creating conditions for flexibly adjusting the relative position of the internal light source 4 components and optimizing the optical path output, while ensuring the stability and maintainability of the overall structure.

[0030] In one embodiment, the first tube 81 can be made of engineering plastics with excellent mechanical strength and weather resistance, such as nylon (PA), polycarbonate (PC), or acrylonitrile-butadiene-styrene copolymer (ABS), or metal materials such as brass or aluminum alloy. Using such materials ensures that the first tube 81 has sufficient structural strength to withstand repeated twisting mechanical stress, and that the first external thread on its outer wall and the internal thread on its inner wall maintain precise tooth profile and durability, achieving a stable and smooth fit with the threaded hole and T-shaped plate 82. Simultaneously, these materials possess good dimensional stability and resistance to high and low temperatures, maintaining shape and function stability under the baking and daily use conditions of polymer clay products, and are not easily deformed or aged, thus ensuring the long-term reliability of the sealing and regulating functions.

[0031] In one embodiment, such as Figure 2 As shown, the transverse section 821 of the T-shaped plate 82 is coaxially arranged with the first tube 81, and a second external thread is provided along the axial direction on the circumferential wall of the transverse section 821 of the T-shaped plate 82. Through the cooperation of the second external thread and the internal thread, the transverse section 821 of the T-shaped plate 82 is threadedly inserted into the first tube 81. The vertical section 822 of the T-shaped plate 82 is used to block the opening at one end of the first tube 81 located outside the mounting hole 2. The lamp wire 3 is rotatably arranged on the T-shaped plate 82 along the axial direction. By adjusting the depth of the transverse section 821 of the T-shaped plate 82 in the first tube 81, the relative position of the light source 4 in the polymer clay body 1 can be adjusted by the lamp wire 3. The light source 4 is movably arranged in the reinforcing cover 6.

[0032] This embodiment constructs a precise fine-tuning mechanism through the threaded engagement of the T-shaped plate 82 and the first tube 81, and the rotational setting of the lamp wire 3 on the T-shaped plate 82. Rotating the T-shaped plate 82 allows for precise control of the forward and backward movement of the T-shaped plate 82, along with the lamp wire 3 and the light source 4, along the axial direction of the mounting hole 2, through the engagement of its second external thread with the internal thread of the first tube 81. This enables flexible adjustment of the relative position of the light source 4 within the reinforcing cover 6. This innovative design allows users to finely optimize the focal point of the light source 4 relative to the trumpet-shaped reinforcing cover 6 according to their needs after product assembly and during use. It achieves dynamic calibration and personalized adjustment of the light emission angle, light convergence, and final lighting effect, greatly improving the controllability and adaptability of the product's optical performance and ensuring the most ideal, uniform, and soft light emission performance is always achieved.

[0033] In one embodiment, the T-shaped plate 82 can be made of engineering plastics with good mechanical properties and dimensional stability, such as polyoxymethylene (POM), nylon (PA66), or reinforced polycarbonate, or lightweight and wear-resistant metals such as aluminum alloy or brass. Using such materials ensures that the transverse section 821 of the T-shaped plate 82 has sufficient strength to withstand repeated twisting torque, and that the second external thread on its circumferential wall remains precise and wear-resistant, achieving a smooth, precise, and durable fit with the internal thread of the first tube 81, avoiding stripping or wear. Simultaneously, the vertical section 822 of the T-shaped plate 82 must reliably seal the tube opening and support the rotation of the lamp wire 3. The selected material should possess both rigidity and toughness to ensure that it does not deform or crack under long-term adjustment and use, thereby ensuring the smooth operation, accurate positioning, and long-term reliability of the entire light source 4 position fine-tuning mechanism.

[0034] In one embodiment, the number of light sources 4 is set to several, and these light sources 4 are arranged at equal intervals along the axial direction of the light line 3. This equidistant arrangement ensures that the light can achieve uniform and continuous illumination along the length of the polymer clay body 1, effectively avoiding the appearance of local bright spots or dark areas, thus creating a consistent brightness and visually comfortable overall luminous effect. Secondly, this regular array layout facilitates the rational distribution of light energy, allowing each light source 4 to independently and efficiently illuminate its corresponding area of ​​polymer clay material, complementing each other and jointly improving the uniformity of illumination and the light efficiency of the entire decorative light. Furthermore, this design provides the hardware foundation for creating dynamic light and shadow patterns (such as flowing water, chasing, and other lighting effects), greatly enhancing the product's artistic expression and scene adaptability.

[0035] In one embodiment, the polymer clay body 1 is provided with a connecting hole and several light guide channels. The connecting hole is connected to the mounting hole 2, and the end of the connecting hole near the mounting hole 2 faces the light source 4 to guide the light emitted by the light source 4 into the connecting hole. The light inlets of the several light guide channels are all connected to the end of the connecting hole away from the mounting hole 2, and the light outlets are distributed around the polymer clay body 1 to achieve multi-point light emission. This embodiment constructs an efficient light distribution and transmission network by setting a connecting hole connected to the mounting hole 2 and several light guide channels distributed around the polymer clay body 1. This structure can effectively collect the core light emitted by the light source 4 through the connecting hole and act as a "light hub" to distribute the light to each light guide channel. The light guide channels utilize the principle of total internal reflection of light in transparent or translucent materials to efficiently transmit light from the light inlets to each preset light outlet on the surface of the polymer clay body 1 away from the light source 4. This design achieves the effect of illuminating multiple areas of the entire product with a single or a few light sources 4. It not only greatly saves energy and the cost of light wires 3 and avoids the tediousness of multiple light wires 3 being tangled, but more importantly, it creates a uniform, staggered and three-dimensional multi-point luminous pattern on the surface of the polymer clay body 1, which significantly enhances the visual hierarchy and artistic expression of the product.

[0036] To address the problems existing in the prior art, embodiments of the present invention provide a method for preparing festive decorative lights, such as... Figure 3 As shown, it includes the following steps: S1: Provide a malleable polymer clay blank and a light-emitting component, the light-emitting component including a lamp line 3 and at least one light source 4 disposed on the lamp line 3.

[0037] Specifically, two core materials are required: first, a malleable polymer clay blank, typically made from PVC, plasticizers, and colorants through mechanical mixing, which can be molded into the desired shape at room temperature; and second, a light-emitting component, which consists of a light wire 3 serving as a conductive carrier, and at least one light source 4 (such as a light-emitting diode) fixedly mounted on the light wire 3. This step is fundamental to all subsequent processes. The properties of the selected polymer clay blank directly determine the final product's shaping capabilities and texture, while the specifications and quality of the light-emitting component affect the product's luminous performance and reliability. The optimal selection and preparation of both lay a solid material foundation for the smooth operation of the entire production process and the high quality of the final product.

[0038] S2: Wrap the polymer clay blank around the light-emitting component, so that the light source 4 is embedded and fixed in the polymer clay blank to form a green body.

[0039] In step S2, the prepared polymer clay blank is completely wrapped around the light-emitting component by hand shaping or molding. This process ensures that the light wire 3 is covered by the blank, and that the light source 4 is precisely embedded and fixed in the predetermined position within the polymer clay blank, thus forming a structurally integrated, uncured green body. This step is the core innovation of this preparation method; it achieves a physical bond between the light-emitting component and the polymer clay material, laying the structural foundation for achieving uniform internal transmission of the light source 4 after subsequent baking and shaping.

[0040] S3: Place the entire green clay body in an oven and bake it at a constant temperature of 130°C to 140°C for 20 to 40 minutes to solidify and shape the polymer clay body.

[0041] In step S3, the green clay body, already wrapped with the light-emitting components, is placed as a whole and stably placed in an oven preheated to 130°C to 140°C, where it is baked for 20 to 40 minutes under constant temperature conditions. This heat treatment process aims to cause the PVC and plasticizers in the polymer clay body to undergo a cross-linking and curing reaction, thereby achieving a physicochemical transformation from a plastic state to a hard and stable state, completing the shaping process. This step is crucial for achieving the structural stability and functionality of the product in the entire method. Its specific temperature and time parameters ensure that while the polymer clay body 1 is fully cured, the internal light-emitting components (such as LED beads) will not be damaged by overheating.

[0042] S4: After the baked product is cooled to below 60°C, it is taken out to obtain a polymer clay luminescent product with the luminescent component integrated inside.

[0043] In step S4, the specific operation involves turning off the heat source of the baked and shaped product along with the oven, or moving it to a safe area for natural or assisted cooling until the product temperature drops below 60°C before removing it. This cooling process is crucial, as it allows the polymer clay body 1, which has been cured at high temperatures, and its integrated light-emitting components to shrink together at a gradual rate to a stable state, effectively preventing product cracking, deformation, or internal stress damage that may occur due to sudden temperature changes. Thus, a structurally integrated and stable finished product is finally obtained—a polymer clay luminescent product with perfectly integrated light-emitting components that allows light to be uniformly transmitted from within the polymer clay material.

[0044] In one embodiment, in step S2, the polymer clay blank is wrapped around the light-emitting component using a molding process: the light-emitting component is placed in the cavity of an inner mold, then the polymer clay blank is filled into the cavity and covers the light-emitting component, and finally demolded to form the green body. This embodiment achieves high precision, high efficiency, and high consistency in product manufacturing. By pre-positioning the light-emitting component precisely within the cavity of the inner mold before filling it with the polymer clay blank, this process ensures that the blank uniformly and densely covers the component, especially ensuring that the light source 4 is in a preset, precise position. This not only guarantees the standardization of the size and shape of each product, effectively avoiding problems such as uneven thickness, incomplete coverage, or positional deviation that may occur with manual wrapping, but also makes it very suitable for mass production, significantly improving production efficiency and product yield, and laying a reliable molding foundation for achieving a stable and uniform light-emitting effect in the final product.

[0045] In one embodiment, in step S2, the polymer clay blank is wrapped around the light-emitting component using a hand-molding method: the polymer clay blank is directly shaped and wrapped around the outside of the light-emitting component. This embodiment provides the product manufacturing process with extremely high artistic flexibility and personalized customization capabilities. By directly shaping the polymer clay blank by hand and wrapping it around the light-emitting component, artists or makers can fully unleash their creativity and freely create various complex, unique, or organic shapes, which is difficult to achieve with mold molding. This method is particularly suitable for small-batch production of works with high artistic requirements, allowing the maker's skills and emotions to be integrated into the product, giving each finished product a unique artistic value and greatly expanding the application potential of polymer clay luminous products in creative design and high-end decoration fields.

[0046] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the present invention. Furthermore, the present invention described herein may have other embodiments and can be implemented or carried out in various ways.
