Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a light-emitting device. Background Technology

[0002] In existing technologies, flexible LED filaments are often arranged within a light-transmitting carrier. However, the common methods are limited to hanging them within the carrier, straightening them by mechanically positioning both ends, or allowing the middle of the filament to hang freely within the carrier. These traditional fixed arrangements are clearly insufficient; they are ill-suited to the complex and ever-changing lighting design requirements, and they cannot achieve free shaping and precise positioning of the filament in three-dimensional space.

[0003] This limitation not only severely restricts the improvement of the visual effect and artistic expression of lighting fixtures, but also makes traditional arrangement methods particularly inadequate in scenarios that require creating a specific atmosphere or emphasizing spatial hierarchy, failing to meet designers' deep expectations for delicate control of the lighting environment. Therefore, in response to the shortcomings of existing technology, an innovative design solution is urgently needed to break through these limitations and bring more possibilities and creative space to lighting fixture design.

[0033] When the light-emitting element uses a straight LED filament, its substrate is a straight substrate, which includes a ceramic substrate and a metal substrate.

[0034] Furthermore, the light-emitting body is a three-dimensional graphic or a two-dimensional graphic, which includes a contoured substrate, a light-transmitting adhesive layer, and a light source module.

The light-emitting body is provided with a positive terminal and a negative terminal, and is powered and connected to a drive controller placed inside or outside the light-transmitting carrier.

[0035] The light-emitting body is provided with several support points on its periphery, and each support point is connected to a corresponding connection point or each support point is connected to a corresponding connection point through a traction wire, thereby supporting and restraining the light-emitting body within the receiving cavity.

[0036] Furthermore, a support column or frame is provided inside the light-transmitting carrier, and several support fulcrums are provided on the support column or frame. The light-emitting body is restrained and supported in the receiving cavity through the interaction of each connection point and several support fulcrums.

[0037] Furthermore, the light-transmitting carrier includes glass blister packs, plastic blister packs, and light-transmitting covers made of glass or light-transmitting plastic, as well as woven or perforated mesh covers made of wrought iron, fabric, bamboo, wood, or plastic.

[0038] Furthermore, the light-emitting element is a flexible LED filament, which is supported within the cavity by several elastic traction wires that are respectively restrained at each connection point.

A sliding member is provided on the inner wall of the cavity, and a drive member is provided on the outer wall of the cavity to drive the sliding member to move along the inner wall of the cavity.

A magnetic attractor and a magnetically attracted member are respectively provided between the sliding member and the drive member.

[0039] Furthermore, a planar light source combination is formed by one or more flexible LED filaments winding around each connection point on the same plane within the receiving cavity;

[0040] Alternatively, a planar light source assembly can be formed by several straight LED filaments bound together in the same plane with each connection point as a support point within the receiving cavity;

[0041] Alternatively, a three-dimensional light source combination can be formed by one or more flexible filaments winding around each connection point and intersecting at each connection point within the cavity.

[0042] Alternatively, the three-dimensional light source assembly consists of several straight LED filaments constrained within the receiving cavity by their connection points, forming a three-dimensional light source assembly through interlacing in three-dimensional space.

[0043] Compared with existing technologies, this utility model proposes a method that cleverly utilizes connection points to restrain and support the light-emitting element within a receiving cavity, showcasing the charm of the light-emitting element and breaking away from the traditional fixed arrangement of filaments. Specifically, the flexible LED filament is segmented through connection points, forming a multi-segment, sequentially taut structure, and cleverly placed within the receiving cavity of the light-transmitting carrier; similarly, the straight LED filament is also stably placed within the receiving cavity through corresponding restraint and support at each connection point. Whether using flexible or straight LED filaments, the light-emitting element can be flexibly combined into planar or three-dimensional light sources and restrained within the receiving cavity through connection points. The ability of the LED filament to freely shape and precisely position itself in three-dimensional space enhances the visual effect of the lamp and significantly strengthens its artistic expression, enabling the lamp to better adapt to the lighting needs of different scenes and atmospheres, and to more precisely control the distribution and changes of light, creating a more comfortable and layered three-dimensional lighting effect.

[0044] The flexible LED filament or straight LED filament is positioned and bonded to the corresponding connection point using a traction buckle. The traction buckle is then passed through or connected to the corresponding traction buckle for positioning and restraint. Furthermore, the traction buckle is bonded to a designated position on the inner wall of the receiving cavity via a patch. This is done to facilitate accurate positioning and restraint of the filament and ensure its connection reliability. The traction buckle is a hook, ring, or arc-shaped sleeve. The flexible LED filament is sequentially embedded in each hook, passes through the perforation of each ring, or passes through the arc-shaped channel of each arc-shaped sleeve. Furthermore, by using an arc-shaped groove tube or arc-shaped sleeve as a guide tube for the filament, the smooth, non-sharp transition area formed is conducive to the reception and guidance of the flexible LED filament, avoiding filament breakage.

[0045] The traction clip is bonded to the corresponding connection point via a traction wire. This traction wire can be an elastic connector or a rigid connecting post. Elastic connectors include rubber bands and springs, while rigid connecting posts can be made of materials such as plastic or metal. The choice of traction wire depends on the specific application scenario's requirements for flexibility and stability: in scenarios requiring more flexible and dynamically adjustable filament layouts, elastic connectors such as rubber bands or springs can better adapt to changes in filament shape, maintaining restraint while allowing a certain degree of displacement, enhancing the dynamic feel and adaptability of the lighting effect; while in scenarios where structural stability and maintaining a fixed shape over a long period are desired, rigid connecting posts provide more reliable support, ensuring the filament position remains stable and improving the overall durability of the luminaire.

[0088] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0089] Please refer to Figures 1-25 As shown, the light-emitting device of this utility model includes a light-transmitting carrier 1 and a light-emitting body 200. The light-transmitting carrier 1 forms a receiving cavity 10, and a plurality of connection points 4 are provided on the inner wall of the receiving cavity 10. The connection points 4 can also be defined as connection points, mounting points, support points, or fixing points. Each connection point 4 of the light-emitting body 200 is restrained and supported and connected to the receiving cavity 10. By providing multiple connection points in the receiving cavity 10, it is convenient to arrange and shape the light-emitting body 200 within the light-transmitting carrier.

[0090] The light-emitting element 200 is at least one flexible LED filament 2, which is wound around each connection point 4 and connected to the receiving cavity 10 by mutual restraint of the connection points 4, thereby forming a planar light source combination and a three-dimensional light source combination; or the light-emitting element 200 is a plurality of straight LED filaments 30 connected in series, parallel or series-parallel, which are respectively restrained by each connection point 4 and connected to the receiving cavity 10 to form a planar light source combination and a three-dimensional light source combination. Through the above restraint settings of the light-emitting element 200, the flexible LED filament 2 or the straight LED filament 30 can be freely shaped and precisely positioned within the light-transmitting carrier 1, thereby adapting to the complex and ever-changing three-dimensional lighting design requirements formed by flexible LED filaments.

[0091] The planar light source assembly is formed by one or more flexible LED filaments 2 wound around various connection points 4 on the same plane within the receiving cavity 10, or by several straight LED filaments 30 constrained within the receiving cavity 10 on the same plane with each connection point 4 as a support point. This layout allows the flexible LED filaments 2 to unfold on a two-dimensional plane and be fixed and supported by the connection points, thereby forming a stable and uniform planar light source. Due to the flexibility and bendability of the flexible LED filaments 2, and the flexible setting of the connection points, the planar light source assembly can adapt to light-transmitting carriers of various shapes and sizes. Through reasonable layout and support of connection points, the planar light source assembly optimizes the energy efficiency of the light source and reduces energy consumption. Alternatively, these straight LED filaments are precisely arranged on the same plane and kept stable by the connection points, thereby forming a continuous and uniform planar light source. The regular arrangement of the straight LED filaments on the plane ensures uniform light distribution, reduces light spots and shadows, and improves the consistency and comfort of lighting.

[0092] The three-dimensional light source assembly is formed by one or more flexible LED filaments 2 winding around various connection points 4 and intersecting within the cavity 10, with each connection point 4 serving as a turning point; for example... Figure 4 , 5 As shown in Figure 10, the three-dimensional light source assembly consists of several straight LED filaments 30, each supported by a connection point 4, held within the receiving cavity 10 and arranged in a three-dimensional, interwoven manner. This layout allows both the flexible LED filaments 2 and the straight LED filaments 30 to unfold in three-dimensional space, creating a three-dimensional lighting effect and giving the light source a rich sense of layering and three-dimensionality. In other words, the three-dimensional light source assembly breaks the limitations of traditional planar lighting, forming a three-dimensional lighting effect with depth and layering. It also fully utilizes the space within the light-transmitting carrier, increasing the density and brightness of the light source while reducing the space occupied, making the lighting design more compact and efficient. The three-dimensional light source assembly has a stronger sense of three-dimensionality and dynamism, attracting attention and enhancing the visual impact and artistic feel of the space.

[0093] The light-transmitting carrier 1 includes glass bulbs, plastic bulbs, and light-transmitting covers made of glass or translucent plastic, as well as woven or perforated mesh covers made of wrought iron, fabric, bamboo, wood, or plastic. The glass bulbs provide a clear and bright display window for the internal light-emitting element 200, while protecting it from external environmental interference. The manufacturing process for glass bulbs is mature, and they come in various shapes, such as spheres and cylinders. The light-transmitting covers can be injection molded into bulb shapes, covers, or even multifaceted geometric shapes to create unique lighting effects. The choice of glass or translucent plastic ensures good light transmittance while providing sufficient structural strength. The woven or perforated design not only allows light to pass through, creating soft, dappled light and shadow effects, but also provides a degree of protection for the light-emitting element 200.

[0094] The flexible LED filament 2 is segmented at each connection point 4, forming a multi-segment, sequentially straightened structure. This multi-segment straightening structure allows for more accurate filament movement and positioning, facilitating complex three-dimensional lighting effects, enriching its design possibilities and application scenarios. Furthermore, the connection points 4 facilitate the sequential segmenting and assembly of the flexible LED filament 2.

[0095] The flexible LED filament 2 or the straight LED filament 30 is positioned and bonded to the corresponding connection points 4 using adhesive. That is, in actual use, the flexible LED filament 2 can be directly bonded to each connection point 4 with adhesive to fix it to the inner wall of the receiving cavity 10.

[0096] Each connection point 4 is connected to a traction buckle 40, through which the flexible LED filament 2 or straight LED filament 30 passes or connects to the corresponding traction buckle 40. Specifically, the flexible LED filament 2 or straight LED filament 30 can easily pass through or directly connect to the corresponding traction buckle 40. This design not only enhances the stability of the filament within the receiving cavity 10 but also greatly enriches the layout and styling possibilities of the light. Furthermore, each traction buckle 40 is respectively bonded to each connection point 4 via a patch 41. One or more traction buckles 40 are bonded to the corresponding connection point 4 via a traction wire 50, which is an elastic connector or a rigid connector. The elastic connector includes rubber bands and springs. One end of the traction wire 50 is connected to the traction buckle 40, and the other end is bonded to the corresponding connection point via the patch 41. This patch design not only simplifies the installation process but also improves the reliability of the connection. At the same time, one or more traction buckles 40 can also be connected to the corresponding connection point 4 via the traction wire 50. This design makes the connection between the traction buckle and the connection point more flexible and diverse. To maintain the transparency and overall aesthetics of the lighting, both the traction wire 50 and the patch 41 are transparent structural components. The adhesive used for bonding is generally UV adhesive.

[0097] Please refer to Figures 1-40 As shown, the traction buckle 40 is a hook 401, a ring buckle 402, or an arc-shaped sleeve 403. The flexible LED filament 2 sequentially wraps around or passes through the hook 401, ring buckle 402, or arc-shaped sleeve 403 at the corresponding connection point 4. The channel 403 for passing through the flexible LED filament 2 is an arc-shaped channel 400. The hook 401 is suitable for scenarios that require tight fixation and have clear requirements on the filament direction; the ring buckle 402 is more suitable for situations where the filament needs to be freely passed through in multiple directions; while the arc-shaped sleeve 403, with its unique arc-shaped channel 400, provides a smoother path for the flexible LED filament 2 to pass through, and at the same time protects the filament from damage to a certain extent.

[0098] like Figure 32 , 33 As shown, an arc-shaped groove 404 is provided on the hook 401 or the ring 402 where the flexible LED filament 2 passes; or as... Figure 30 , 31 As shown, the arc-shaped sleeve 403 is set on the hook 401 or the ring 402 as a guide tube for the flexible LED filament 2. By using the arc-shaped groove tube 404 or the arc-shaped sleeve 403 as the guide tube for the filament, the smooth, non-sharp transition area formed is conducive to the accommodation and guidance of the flexible LED filament, avoiding filament breakage. While maintaining the transparency and overall aesthetics of the light, we further optimized the design of the traction buckle 40. Specifically, we cleverly set the arc-shaped groove tube 404 on the hook 401 or the ring 402 at the position where the flexible LED filament 2 passes, thus providing a smoother path for the flexible LED filament 2 to pass through, avoiding possible breakage or twisting of the filament during the passing process, thereby ensuring the continuity and stability of the light. At the same time, the transparent material and exquisite design of the arc-shaped groove tube 404 are perfectly integrated into the overall aesthetics of the light, without compromising the transparency and visual experience of the light. In addition, we also provide a solution to set the arc-shaped sleeve 403 on the hook 401 or the ring 402. That is, the arc-shaped sleeve 403 serves as a guide tube for the flexible LED filament 2. It can not only ensure the smoothness and safety of the filament during the installation process, but also add an elegant arc beauty to the light through its unique arc design. This design not only enhances the aesthetic value of the light, but also further demonstrates the ingenuity of this utility model in the details.

[0099] Furthermore, the curved outer side of the arc-shaped sleeve 403 is designed with a sharp angle. When the flexible LED filament 2 is lit, it passes through the arc-shaped sleeve 403. Because the arc-shaped sleeve 403 is made of a light-transmitting material, the visual effect of the flexible LED filament 2 passing through the arc-shaped sleeve 403 is a crisp bending effect, while in reality, the flexible LED filament 2 still maintains an arc transition within the arc-shaped channel 400. Alternatively, the arc-shaped sleeve 403 can be designed as a non-light-transmitting material, thus making the segmentation effect of the flexible LED filament between each connection point more obvious and enhancing the design aesthetic.

[0100] The traction buckle 40, patch 41, and sling or column 42 are all transparent components. The arc-shaped groove tube 404 or arc-shaped sleeve 403 is a transparent plastic component, ensuring smooth light transmission and preventing the brightness and uniformity of the light from being affected by obstruction or absorption. The light-transmitting carrier 1 is a glass bulb, a plastic bulb, or a light-transmitting cover made of glass or light-transmitting plastic. The patch 41 can be a transparent patch, so that when it is adhered to the inner wall of the receiving cavity, it appears as invisible as possible, thereby improving the visual effect. The patch 41 can be made into a rectangle, a circle, or a flower shape. The sling or column 42 is made of transparent plastic, with the sling being a flexible strip and the column being a hard plastic. In different usage scenarios, the purpose is to make the flexible LED filament 2 appear to float in the receiving cavity 10, that is, its surrounding connection points are all transparent, and after being lit, the flexible LED filament 2, except for the power supply end, appears to be suspended in the light-transmitting carrier 1, visually separating it from the receiving cavity 10. Similarly, the arc-shaped groove tube 404 or the arc-shaped sleeve 403 is a transparent plastic part, so as to keep the entire filament transparent and emitting light; or the arc-shaped groove tube 404 or the arc-shaped sleeve 403 is made of a non-transparent material, so that the entire flexible LED filament 2 presents a clear segmented visual effect when it wraps around or passes through the arc-shaped groove tube 404 or the arc-shaped sleeve 403.

[0101] The connection point 4 is connected to a light-transmitting particle 43, and each light-transmitting particle 43 is provided with a through hole 431. Its outer wall is correspondingly adhered to the connection point. The light-transmitting particle 43 is a crystal bead, silicone bead, rubber bead, plastic light-transmitting bead, or glass bead. The plastic light-transmitting beads include plastic fluorescent beads mixed with phosphor. They not only have excellent light transmission performance, but also enhance the flickering and refraction effect of the light, making the light more dazzling. By selecting light-transmitting particles of different colors, shapes, and sizes, a variety of lighting effects can be created to meet the user's needs for personalized lighting. The flexible LED filament 2 passes through or is connected to the through hole 431 so that the flexible LED filament 2 can be easily passed through or connected to it; or one or both ends of the straight LED filament 30 are connected to the through hole 431, thereby realizing a more diversified lighting layout and shaping effect.

[0102] like Figure 17, 18 As shown, each connection point 4 inside or outside the cavity is provided with a first magnetic chuck 44 at a corresponding position. The flexible LED filament 2 is positioned and bonded with several second magnetic chucks 45 along its length, and the flexible LED filament 2 is connected to each first magnetic chuck 44 via each second magnetic chuck 45. Each second magnetic chuck 45 is bonded to the flexible LED filament 2 on one side; or the second magnetic chuck 45 has a through hole, through which the flexible LED filament 2 passes and is positioned and bonded to each other. One of the first magnetic chuck 44 and the second magnetic chuck 45 is a permanent magnet, and the other magnetic chuck is a permanent magnet or a metal magnetized body. Through the magnetic connection of the first magnetic chuck 44 and the second magnetic chuck 45, a quick and convenient connection and positioning of the flexible LED filament 2 and the light-transmitting carrier 1 is achieved, which also facilitates the installation and maintenance of the flexible LED filament 2. This connection method reduces the complex structure and operation steps required by traditional fixing methods, improving production efficiency and ease of use.

[0103] like Figure 21 As shown, the inner wall of the receiving cavity 10 has through holes 100 corresponding to each connection point, and each hole is plugged with a sealing plug 46. The sealing plug 46 located on one side of the receiving cavity 10 serves as a connection point, and the flexible LED filament 2 is bonded, fastened, or passed through this connection point. The sealing plug 46 includes a limiting cap 461, a plug 462, and a sealing ring 463. The limiting cap 461 is connected to one end of the plug 462 on one axial side. The sealing ring 463 is sleeved on the plug 462. The sealing plug 46 passes through the plug 462 from the outer wall of the receiving cavity 10 into the through hole 100 and is sealed to the through hole 100 by the sealing ring 463. The limiting cap 461 is connected to the outer wall of the receiving cavity 10 located outside the through hole 100. The end of the plug 462 located inside the receiving cavity 10 serves as a connection point 4, and the flexible LED filament 2 is connected to the connection point 4 through the connection point. A through hole 100 is made in the inner wall of the receiving cavity 10 and a sealing plug 46 is installed. The function of the sealing plug 46 is that when the glass bulb is used as the receiving cavity 10, if the hole in the glass is not blocked, the glass bulb will easily resonate when subjected to external vibration or sound sources, thus causing the inverted glass bulb to resonate and shatter. As a connection point, it not only seals the light-transmitting carrier 1, preventing external dust, moisture, etc. from entering the receiving cavity 10 and affecting the working performance and lifespan of the flexible LED filament 2, but also facilitates the connection and fixation of the flexible LED filament and the connection point. This utility model, by installing the sealing plug 46, not only achieves the connection and fixation of the flexible LED filament 2 and the connection point, but also ensures the airtightness of the light-transmitting carrier 1, preventing external dust, moisture, etc. from entering the receiving cavity and affecting the working performance and lifespan of the flexible LED filament 2.

[0104] This utility model also provides various configuration methods for the drive controller and power supply to adapt to different usage scenarios and needs. For example, the drive controller can be set inside or outside the lamp holder, forming a light source circuit and a charging circuit with components such as a rechargeable lithium battery and a switch; or, the drive controller can also be set inside or outside the lamp head, forming a light source circuit with components such as an external power supply and a switch, as follows:

[0105] Option 1: As Figure 19-21 As shown, a lamp holder 5 is provided on one side of the light-transmitting carrier 1, and a switch 6 is provided on the lamp holder 5. The drive controller 3 is located inside the lamp holder 5. A rechargeable lithium battery 7 and a charging connector 8 are also provided inside the lamp holder 5. The rechargeable lithium battery 7, the switch 6, the flexible LED filament 2 and the drive controller 3 are electrically connected to form a light source circuit. The rechargeable lithium battery 7, the charging connector 8 and the drive controller 3 are electrically connected to form a charging circuit.

[0106] Option 2: Figure 1 , 2 As shown in 12, 14-17, 22, and 23, an external power supply is provided outside the lamp holder 5. The external power supply, switch 6, flexible LED filament 2, and drive controller 3 are electrically connected to form a light source circuit. A lamp head 9 is provided on one side of the light-transmitting carrier 1. The drive controller 3 is located inside the lamp head 9. The flexible LED filament 2 is electrically connected to the lamp head 9 through the drive controller 3.

[0107] like Figure 24 , 25 As shown, both the flexible LED filament 2 and the straight LED filament 30 include a substrate 21, a light-transmitting adhesive layer 22, and a light source module. The light source module is composed of several light-emitting chips 20 connected in series, parallel, or series-parallel via conductive lines. The light source module is laid along the length of the flexible substrate 21, and the light-transmitting adhesive layer 22 covers the light source module and encapsulates it onto the substrate 21. One end of the substrate 21 is provided with a positive electrode pin 23 and a negative electrode pin 24, or one end of the flexible substrate 21 is provided with a positive electrode pin 23, and the other end is provided with a negative electrode pin 24. The positive terminal of the light source module is electrically connected to the positive electrode pin 23, and its negative terminal is electrically connected to the negative electrode pin 24.

[0108] When the light-emitting body 200 adopts a flexible LED filament 2, its substrate 21 is a flexible substrate, which includes a polyimide film and a polyester film.

[0109] When the light-emitting body 200 uses a straight LED filament 30, its substrate 21 is a straight substrate, which includes a ceramic substrate and a metal substrate.

[0110] like Figure 6-9As shown, the light-emitting body 200 is a three-dimensional graphic or a two-dimensional graphic 70. The three-dimensional graphic or the two-dimensional graphic includes a contoured substrate 72, a light-transmitting adhesive layer 71, and a light source module 70. The light source module 70 is composed of several light-emitting chips 73 connected in series, parallel, or series-parallel via conductive lines. The light source module 70 is laid on the contoured substrate 72, and the light-transmitting adhesive layer 71 covers the light source module 70 and encapsulates it onto the contoured substrate 72. The light-emitting body 200 is provided with a positive terminal 74 and a negative terminal 75 for power supply to the drive controller 3. Several support points 201 are provided around the light-emitting body 200, and each support point 201 is connected to a corresponding connection point 4 or each support point 201 is connected to a corresponding connection point 4 via a traction wire 50, thereby supporting and restraining the light-emitting body 200 within the receiving cavity 10.

[0111] like Figure 11 As shown, a support column or frame 80 is provided inside the light-transmitting carrier 1, and several support fulcrums 81 are provided on the support column or frame 80. The light-emitting body 200 is restrained and supported in the receiving cavity 10 through the interaction of each connection point 4 and several support fulcrums 81.

[0112] like Figure 22 , 23As shown, the light-emitting body 200 is a flexible LED filament 2, which is supported in the receiving cavity 10 by several elastic traction wires 50 respectively corresponding to the connection points 4. The first end of the flexible LED filament 2 is connected to a drive controller 3 placed inside or outside the light-transmitting carrier 1. A sliding member 90 is provided on the inner wall of the receiving cavity 10, and a drive member 91 is provided on the outer wall of the receiving cavity 10 to drive the sliding member 90 to move along the inner wall of the receiving cavity 10. The middle or end of the flexible LED filament 2 is connected to the sliding member 90. The sliding member 90 and the drive member 91 magnetically clamp the wall of the receiving cavity 10. The sliding member 90 and the drive member 91 are respectively provided with a magnetic attractor and a magnetically attracted member. The light-transmitting carrier 1 is a glass bulb. A lamp head or lamp holder is provided on one side of the glass bulb. The inner cavity of the glass bulb serves as the receiving cavity 10. The sliding member 91 and the drive member 90 are clamped to the inner and outer sides of the glass bulb wall. Specifically, the sliding member 90 has a third magnetic attraction component on the side facing the glass bulb, and the driving member 90 has a fourth magnetic attraction component on the side facing the glass bulb. One of the third or fourth magnetic attraction components is a permanent magnet, and the other magnetic attraction component is either a permanent magnet or a magnetically attracted metal. Through this design, the light-emitting element 200 not only achieves a stable and adjustable support structure for the flexible LED filament 2 within the receiving cavity 10, but also cleverly incorporates magnetic drive technology, thereby enhancing the product's flexibility and practicality. Specifically, the magnetic clamping design between the sliding member 90 and the driving member 91 not only ensures that the two can be tightly and firmly attached to the wall of the glass bulb, but also allows the driving member 91 to drive the sliding member 90 to move smoothly along the inner wall of the receiving cavity 10 through magnetic force. The sliding member 90 is connected to the middle or end of the flexible LED filament, which is the light-emitting body. Thus, when the sliding member 90 moves, the receiving cavity 10 simultaneously pulls the flexible LED filament to change its shape. The flexible LED filament, which is the light-emitting body 200, is itself curved in the receiving cavity 10. The elastic traction wire 50 restrains the flexible LED filament. Therefore, the sliding member 90 has sufficient pulling margin when pulling the flexible LED filament to change its shape, so as not to break or damage the flexible LED filament. In actual manufacturing design, the extension margin of the flexible LED filament and the elastic traction wire 50 needs to be fully considered to avoid the sliding member 90 breaking or damaging the flexible LED filament at the extreme position, or to limit the sliding range of the sliding member 90.

[0117] Installing the flexible LED filament: Electrically connect one end of the flexible LED filament 2 to the drive controller 3 via a wire. Then, sequentially wrap or pass the other end of the flexible LED filament 2 around or through each traction buckle 40 according to the designed path. During the wrapping process, the shape and position of the flexible LED filament 2 can be adjusted as needed to achieve the desired lighting effect. Finally, fix the end of the flexible LED filament 2 to the traction buckle 40 on the last patch 41 to ensure its stability within the light-transmitting carrier 1.

[0118] Complete the circuit connection: Electrically connect the rechargeable lithium battery 7, charging connector 8, switch 6, and flexible LED filament 2 to the driver controller 3 to form a complete light source circuit and charging circuit. Ensure all connections are secure and reliable, without short circuits or open circuits.

[0119] Packaging and Testing: The opening of the light-transmitting carrier 1 is sealed to ensure the airtightness and safety of the luminaire. Then, the luminaire is powered on for testing to check whether the luminous effect of the flexible LED filament 2 meets the design requirements. If necessary, adjustments and optimizations can be made based on the test results.

[0124] Arrangement of light-transmitting particles: Apply an appropriate amount of adhesive material, such as UV-curing adhesive, to the inner wall of the receiving cavity 10 of the light-transmitting carrier 1 or the outer wall of the light-transmitting particles 43. Cure the material by irradiating it with a UV lamp at the designated position to cure and bond it to each corresponding connection point 4. Each light-transmitting particle 43 is provided with a through hole 431 so that the flexible LED filament 2 can pass through.

[0125] Installing the flexible LED filament: After electrically connecting one end of the flexible LED filament 2 to the driver controller 3, it passes through the through-hole 431 on the first light-transmitting particle 43 and winds around each light-transmitting particle 43 according to a preset path. During the winding process, the shape and position of the flexible LED filament 2 can be flexibly adjusted to achieve rich lighting effects. Finally, the end of the flexible LED filament 2 is fixedly connected to the last light-transmitting particle 43.

[0126] Complete circuit connection and packaging testing: Follow the steps in Example 1 to complete the circuit connection, packaging, and power-on testing.

[0127] As can be seen from the above specific embodiments, this utility model achieves the free shaping and precise positioning of flexible LED filaments in three-dimensional space or plane by connecting the traction buckle 40 with the inner wall of the receiving cavity 10 of the light-transmitting carrier 1, thereby breaking through the limitations of the traditional fixed arrangement method and significantly improving the visual effect and artistic expression of the lamp.
