[0002] In the prior art, flexible LED filaments are often placed in a light-transmitting carrier, but their common arrangement is limited to hanging in the light-transmitting carrier, or by mechanically positioning the two ends of the filament and then straightening it, or by letting the middle of the filament fall freely in the light-transmitting carrier. These traditional fixed arrangement methods obviously have shortcomings. They are difficult to adapt to the complex and changing lighting design requirements, and they cannot achieve free shaping and precise positioning of the filament in three-dimensional space.

[0029] The traction buckle is bonded to the corresponding connection point through a traction wire. The traction wire is an elastic connector or a rigid connection column. The elastic connector includes rubber bands and springs, while the rigid connection column can be made of plastic, metal and other materials. The choice of traction wire depends on the flexibility and stability requirements of the specific application scenario: in scenarios where the filament layout needs to be more flexible and dynamically adjustable, elastic connectors such as rubber bands or springs can better adapt to the shape changes of the filament, allowing a certain degree of displacement while maintaining restraint, enhancing the dynamic sense and adaptability of the lighting effect; in scenarios that pursue a stable structure and maintain a fixed shape for a long time, rigid connection columns can provide more reliable support, ensure the stability of the filament position, and improve the overall durability of the lamp.

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Please refer to Figure 1-Figure 25 As shown, a light-emitting device according to the present invention comprises a light-transmitting carrier 1 and a light-emitting body 200. The light-transmitting carrier 1 is formed with a receiving cavity 10. A plurality of connection points 4 are arranged on the inner wall of the receiving cavity 10. The connection points 4 can also be defined as connection points, mounting points, supporting points or fixing points. Each connection point 4 of the light-emitting body 200 is restrained and supported and connected in the receiving cavity 10. By arranging a plurality of connection points in the receiving cavity 10, it is convenient to arrange and shape the light-emitting body 200 in the light-transmitting carrier.

[0033] The luminous body 200 is at least one flexible LED filament 2, each flexible LED filament 2 is wound around each connection point 4 and restrained by each connection point 4 to be connected in the accommodating cavity 10, thereby forming a planar light source combination and a three-dimensional light source combination; or the luminous body 200 is a plurality of straight LED filaments 30 connected in series, in parallel, or in series and parallel, each straight LED filament 30 is restrained by each connection point 4 and connected in the accommodating cavity 10 to form a planar light source combination and a three-dimensional light source combination. Through the above-mentioned restraining arrangement of the luminous body 200, that is, the flexible LED filament 2 or the straight LED filament 30 can be freely shaped and accurately positioned in the light-transmitting carrier 1, thereby adapting to the complex and changeable three-dimensional lighting design requirements formed by the flexible LED filament.

[0034] The planar light source combination is formed by a single or multiple flexible LED filaments 2 winding around each connection point 4 in the same plane in the accommodating cavity 10, or the planar light source combination is formed by a plurality of straight LED filaments 30 in the same plane with each connection point 4 as a support point restrained in the accommodating cavity 10; this layout mode enables the flexible LED filament 2 to be unfolded on a two-dimensional plane, and fixed and supported by the connection points, thereby forming a stable and uniform planar light source. Due to the softness and bendability of the flexible LED filament 2, and the flexible setting of the connection points, the planar light source combination is adapted to light-transmitting carriers of various shapes and sizes; the planar light source combination optimizes the energy efficiency of the light source and reduces energy consumption through reasonable layout and support of the connection points. Or these straight LED filaments are precisely arranged on the same plane and are 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 the uniform distribution of light, reduces light spots and shadows, and improves the consistency and comfort of lighting.

[0035] The three-dimensional light source combination is formed by a single or multiple flexible LED filaments 2 winding around each connection point 4 and intersecting in the space within the accommodating cavity 10 with each connection point 4 as a turning point; Figure 4 , 5 As shown in or 10, the three-dimensional light source combination is formed by a plurality of straight LED filaments 30 which are restrained in the accommodating cavity 10 with each connection point 4 as a support point and staggered in a three-dimensional space. The above layout enables the flexible LED filament 2 or the straight LED filament 30 to be unfolded in a three-dimensional space, creating a three-dimensional lighting effect, so that the light source presents a rich sense of hierarchy and three-dimensionality in the three-dimensional space. That is: the three-dimensional light source combination can break the limitations of traditional planar lighting, form a three-dimensional lighting effect with depth and hierarchy, and can make full use of the space inside the light-transmitting carrier, increase the density and brightness of the light source, and reduce the occupation of the lighting space, making the lighting design more compact and efficient. The three-dimensional light source combination has a stronger sense of three-dimensionality and dynamics visually, which can attract people's attention and enhance the visual impact and artistic sense of the space.

[0036] The light-transmitting carrier 1 includes a glass bulb, a plastic bulb, a light-transmitting cover made of glass or light-transmitting plastic, and a woven or hollow mesh cover formed of iron, cloth, bamboo, and plastic. The glass bulb can provide a clear and transparent display window for the internal light-emitting body 200, while protecting the light-emitting body 200 from interference from the external environment. The manufacturing process of the glass bulb is mature and the shape is diverse, which can be spherical or cylindrical; the light-transmitting cover can be molded by mold injection into a bubble shell, a cover, etc., or even a multi-faceted geometric body to create a unique lighting effect. The material selection of glass or light-transmitting plastic ensures good light transmittance and provides sufficient structural strength. The woven or hollow design not only allows light to pass through, forming a soft and mottled light and shadow effect, but also provides a certain degree of protection for the light-emitting body 200.

[0037] The flexible LED filament 2 is divided into sections at each connection point 4 and then becomes a multi-section straight structure. The multi-section straight structure makes the filament more accurate in shuttling and positioning, facilitates the realization of complex three-dimensional lighting effects, enriches its design possibilities and application scenarios, and the connection points 4 between each other facilitate the flexible LED filament 2 to be straightened and assembled in sections.

[0038] The flexible LED filament 2 or the straight LED filament 30 is positioned and bonded to the connection points 4 at the corresponding positions by glue. That is, in actual use, the flexible LED filament 2 can be directly bonded to the connection points 4 by glue so as to be positioned and fixed on the inner wall of the accommodating cavity 10.

[0039] Each connection point 4 is connected with a traction buckle 40, and the flexible LED filament 2 or the straight LED filament 30 is respectively passed through or connected to the traction buckle 40 at each corresponding position. Specifically, the flexible LED filament 2 or the straight LED filament 30 can be easily passed through or directly connected to the traction buckle 40 at each corresponding position. Such a design not only enhances the stability of the filament in the accommodating cavity 10, but also greatly enriches the layout and modeling possibilities of the light. Further, each traction buckle 40 is bonded to each connection point 4 through a patch 41. One or more traction buckles 40 are bonded to the corresponding connection point 4 through a traction wire 50, and the traction wire 50 is an elastic connector or a rigid connecting column, and the elastic connector includes a rubber band and a spring. One end of the traction wire 50 is connected to the traction buckle 40, and the other end thereof is bonded to the corresponding connection point through a 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 through the traction wire 50. This design makes the connection between the traction buckle and the connection point more flexible and diverse. In order to maintain the transparency and overall aesthetics of the light, the traction wire 50 and the patch 41 are both transparent structural parts. Among them, the glue used for bonding generally adopts UV glue.

[0040] Please refer to Figure 1-Figure 40 As shown, the traction buckle 40 is a hook 401, a ring buckle 402 or an arc sleeve 403, and the flexible LED filament 2 is sequentially wound around or passed through the hook 401, the ring buckle 402 or the arc sleeve 403 on the corresponding connection point 4, wherein the channel in the 403 for passing the flexible LED filament 2 is an arc channel 400. The hook 401 is suitable for scenes that require tight fixation and have clear requirements on the direction of the filament; the ring buckle 402 is more suitable for situations where the filament needs to be freely passed in multiple directions; and the arc sleeve 403 provides a smoother passing path for the flexible LED filament 2 with its unique arc channel 400, and also protects the filament from damage to a certain extent.

[0041] like Fig.32 , 33 As shown, the hook 401 or the buckle 402 is provided with an arc-shaped groove tube 404 at the place where the flexible LED filament 2 is wound; or as Fig.30 , 31As shown, the arc-shaped sleeve 403 is arranged on the hook 401 or the ring buckle 402 to serve as a guide tube for the flexible LED filament 2. By using the arc-shaped slot tube 404 or the arc-shaped sleeve 403 as the guide tube for the filament, the smooth transition area without sharp angles formed is conducive to the accommodation and guidance of the flexible LED filament, avoiding the filament from being damaged. On the premise of 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 slot tube 404 on the hook 401 or the ring buckle 402 at the position where the flexible LED filament 2 is wound, thereby providing a smoother path for the flexible LED filament 2 to be worn, avoiding the damage or distortion that may occur in the filament during the wearing process, thereby ensuring the continuity and stability of the light. At the same time, the transparent material and exquisite design of the arc-shaped slot tube 404 are also perfectly integrated into the overall aesthetics of the light, and will not destroy the transparency and visual experience of the light. In addition, we also provide a solution of setting the arc sleeve 403 on the hook 401 or the buckle 402, that is, the arc sleeve 403 serves as a guide tube for the flexible LED filament 2, which can not only ensure the smoothness and safety of the filament during the threading 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 the present invention in detail processing.

[0042] Furthermore, the curved outer side of the arc sleeve 403 is designed to be sharp-angled, and when the flexible LED filament 2 passes through the arc sleeve 403 of the structure after lighting, the arc sleeve 403 is made of a light-transmitting material, and visually the effect of the flexible LED filament 2 passing through the arc sleeve 403 is a crisp bending effect, while the actual flexible LED filament 2 in the arc channel 400 still has an arc transition. In addition, we can also design the arc sleeve 403 to be a non-light-transmitting material, so that the segmentation effect of the flexible LED filament between each connection point is more obvious visually, and the design sense is stronger.

[0043] The traction buckle 40, patch 41 and sling or hanging column 42 are all transparent parts. The arc-shaped slot tube 404 or arc-shaped sleeve 403 is a transparent plastic part, which ensures the smooth propagation of light and does not affect the brightness and uniformity of light due to obstruction or absorption. The light-transmitting carrier 1 is a glass bulb, a plastic bulb and a light-transmitting cover shell made of glass or light-transmitting plastic. And the patch 41 can be a transparent patch, so that when it is bonded to the inner wall of the accommodating cavity, it is as invisible as possible, thereby improving the visual effect. The patch 41 can be made into a rectangular, circular or flower-shaped shape; the sling or hanging column 42 is made of transparent plastic, wherein the sling is a flexible belt and the hanging column is hard plastic. In different usage scenarios, the purpose is to make the flexible LED filament 2 present a suspension effect in the accommodating cavity 10, that is, the connection points on its peripheral side are all transparent, and after lighting, the flexible LED filament 2 presents a suspension effect in the light-transmitting carrier 1 except for the power-taking end, and visually it is separated from the accommodating cavity 10. Similarly, the arc-shaped slot tube 404 or the arc-shaped sleeve 403 is a transparent plastic part, so as to keep the entire section of the filament translucent and luminous; or the arc-shaped slot tube 404 or the arc-shaped sleeve 403 is made of non-translucent material, so that the entire section of the flexible LED filament 2 presents an obvious segmented visual effect when it is wrapped around or passed through the arc-shaped slot tube 404 or the arc-shaped sleeve 403.

[0044] The connection point 4 is connected to a light-transmitting particle 43, each of which is provided with a through hole 431, and its outer wall is correspondingly bonded to the connection point. The light-transmitting particle 43 is a crystal bead, a silicone bead, a rubber bead, a plastic light-transmitting bead or a glass bead. The plastic light-transmitting bead includes a plastic fluorescent bead mixed with fluorescent powder. They not only have excellent light-transmitting performance, but also can enhance the flickering and refraction effects of the light, making the light more dazzling. By selecting light-transmitting particles of different colors, shapes and sizes, colorful lighting effects can be created to meet the user's needs for personalized lighting; the flexible LED filament 2 is passed through or connected to the through hole 431, so that the flexible LED filament 2 can be easily passed through or connected thereto; or one end or both ends of the straight LED filament 30 are connected to the through hole 431, so as to achieve a more diversified lighting layout and modeling effect.

[0045] like Fig.17 , 18As shown, a first magnetic member 44 is provided at a corresponding position of each connection point 4 inside or outside the accommodating cavity, and the flexible LED filament 2 is provided with a plurality of second magnetic members 45 positioned and bonded along its length direction, and the flexible LED filament 2 is connected to each first magnetic member 44 through each second magnetic member 45; wherein, one side of each second magnetic member 45 is bonded to the flexible LED filament 2; or a through hole is provided on the second magnetic member 45, and the flexible LED filament 2 is positioned and bonded to each other after passing through the through hole; if one of the first magnetic member 44 and the second magnetic member 45 is a permanent magnet, the other magnetic member is a permanent magnet or a metal magnet. Through the magnetic connection of the first magnetic member 44 and the second magnetic member 45, the connection point between the flexible LED filament 2 and the light-transmitting carrier 1 is quickly and conveniently connected and positioned, and the installation and maintenance of the flexible LED filament 2 is also facilitated. This connection method reduces the complex structure and operation steps required by the traditional fixing method, and improves production efficiency and convenience of use.

[0046] like Fig.21 As shown, the inner wall of the accommodating cavity 10 is provided with through holes 100 corresponding to the positions of the connection points, and the sealing plugs 46 are respectively blocked; and the sealing plugs 46 located on one side of the accommodating cavity 10 serve as the connection points, and the flexible LED filament 2 is respectively bonded, buckled or connected with the connection points. The sealing plug 46 includes a limit cover 461, a plug 462, and a sealing ring 463.

A through hole 100 is opened on the inner wall of the accommodating cavity 10 and a sealing plug 46 is installed to block the hole. The function of the sealing plug 46 is that when a glass bulb is used as the accommodating cavity 10, after a hole is opened on the glass, if it is not blocked, when the outside world receives a vibration source or a sound source, the glass bulb is easy to resonate, so that the inverted glass bulb resonates and explodes; and as a connection point, it not only realizes the sealing of the light-transmitting carrier 1, but also prevents external dust, water vapor, etc. from entering the accommodating cavity 10 to affect the working performance and life of the flexible LED filament 2; at the same time, the design of the sealing plug 46 also facilitates the connection and fixation of the flexible LED filament and the connection point.

[0050] like Figure 6-9As shown, the luminous body 200 is a three-dimensional image or a two-dimensional image 70, which includes a contour substrate 72, a light-transmitting adhesive layer 71 and a light source module 1. The light source module 1 is composed of a plurality of light-emitting chips 73 connected in series, in parallel or in series and in parallel through conductive lines. The light source module 1 is laid on the contour substrate 72, and the light-transmitting adhesive layer 71 covers the light source module 1 and is coated on the contour substrate 72; the luminous body 200 is respectively provided with a positive terminal 74 and a negative terminal 75 which are electrically connected to the drive controller 3; a plurality of fulcrums 201 are arranged around the luminous body 200, and each fulcrum 201 is correspondingly connected to each connection point 4 or each fulcrum 201 is correspondingly connected to each connection point 4 through a pull rope 50, so that the luminous body 200 is supported and restrained in the accommodating cavity 10.

[0051] like Fig.11 As shown, a support column or frame 80 is provided in the light-transmitting carrier 1, and a plurality of supporting fulcrums 81 are further provided on the support column or frame 80. The light-emitting body 200 is restrained and supported in the accommodating cavity 10 through the interaction between each connection point 4 and a plurality of supporting fulcrums 81.

[0052] like Fig. 22 , 23As shown, the light-emitting body 200 is a flexible LED filament 2, which is supported in the accommodating cavity 10 by a plurality of elastic traction wires 50 respectively corresponding to each connection point 4. The head end of the flexible LED filament 2 is electrically connected to a driving controller 3 placed inside or outside the light-transmitting carrier 1. A sliding member 90 is arranged on the inner wall of the accommodating cavity 10, and a driving member 91 for driving the sliding member 90 to move along the inner wall of the accommodating cavity 10 is arranged on the outer wall of the accommodating cavity 10. The middle part or the end of the flexible LED filament 2 is restrained and connected with the sliding member 90; the sliding member 90 and the driving member 91 magnetically clamp the wall of the accommodating cavity 10; the sliding member 90 and the driving member 91 are respectively provided with a magnetic attraction member and a magnetically attracted member between each other, and the light-transmitting carrier 1 is a glass bulb shell, and a lamp holder or a lamp holder is arranged on one side of the port of the glass bulb shell. The inner cavity of the glass bulb shell serves as the accommodating cavity 10, and the sliding member 91 and the driving member 90 clamp the inner and outer sides of the shell wall of the glass bulb shell.

The sliding member 90 is connected to the middle or end of the flexible LED filament as a light-emitting body, so that when the sliding member 90 moves, the flexible LED filament is synchronously pulled by the accommodating cavity 10 to change its shape. The flexible LED filament as the light-emitting body 200 is itself curved in the accommodating cavity 10, wherein the elastic traction wire 50 restrains the flexible LED filament, so the sliding member 90 has sufficient pulling margin when pulling the flexible LED filament to change its shape, so that the flexible LED filament will not be torn or damaged. In actual production and design, it is necessary to fully consider the stretching margin of the flexible LED filament and the elastic traction wire 50 to avoid the sliding member 90 from tearing or damaging the flexible LED filament when it is in the extreme position, or to limit the sliding action range of the sliding member 90.
