[0039] Embodiment 1

[0040] Please refer to Figures 1 to 5 , the light-emitting mechanism includes two support parts 1, 1' and N flexible light strips 2 of LEDs.

The ends of the N flexible light strips 2 are respectively fixedly connected to the N first protruding parts 11, 11' on the support parts 1, 1'. The two support parts 1, 1' are respectively the first support part 1 and the second support part 1'. A plurality of second protruding parts 12 are fixedly arranged on the first support part 11 at equal intervals along the height of the support part. The N first protruding parts 11 and the N second protruding parts 12 are arranged on both sides of the first support part 11 at the same height. Each end of the second protruding part 12 is provided with the above-mentioned connecting part 13, and the connecting part 13 is such as a card slot or a snap or a hook. The two support parts 1, 1' are in a rod structure and are made of a conductive metal material to have electrical conductivity. Through the fixed connection of the support parts 1, 1' and the ends of the flexible light strips 2, the two support parts 1, 1' are respectively electrically connected to the two poles of the flexible light strips 2, and the fixed connection is such as welding. The material of the flexible light strip 2 includes but is not limited to FPC / ceramics / metal. In this embodiment, the N flexible light strips 2 are arranged in parallel, but this is not a limitation. According to needs, a non-parallel manner can also be adopted.

[0041] The light-emitting device includes a light-emitting mechanism as described above, a stem 3, and two conductive wires 4. The two support portions 1 and 1' of the light-emitting mechanism are fixedly connected to the stem 3. By the fixed connection, the distance between the two support portions 1 and 1' is smaller than the length of the flexible light strip 2. The N flexible light strips 2 surround the two support portions 1 and 1', and the N flexible light strips 2 are respectively mounted on N connecting portions 13 of the first support portion 1 to support the flexible light strip 2 through the connecting portions 13 of the support portion 1 and the two support portions 1 and 1', such as clamping the flexible light strip 2 in a card slot or a snap or a hook. The two conductive wires 4 are fixedly inserted into the stem 3. The two support portions 1 and 1' are fixedly inserted into the stem 3, and the two support portions 1 and 1' and the two conductive wires 4 are electrically connected respectively. In this embodiment, the two support portions 1 and 1' are arranged at the same height. The N flexible light strips 2 surround the two support portions 1 and 1' and form an arc structure with a central angle greater than 180 degrees. This embodiment is not limited to the arc structure. According to needs, a similar internal and external spiral structure like a torsion spring can also be set.

[0042] The flexible filament lamp includes a light-emitting mechanism as described above, a stem 3, two conductive wires 4, a lamp cap 5 for installing the stem 3, a bulb shell 6, and a driving circuit 7 for driving the flexible light strip 2 to emit light. The two support portions 1 and 1' of the light-emitting mechanism are fixedly connected to the stem 3. The bulb shell 6 is mounted on the lamp cap 5 and covers the light-emitting device. The driving circuit 7 is arranged inside the lamp cap 5. The lamp cap 5 and the driving circuit 7 are electrically connected. The driving circuit 7 and the two conductive wires 4 are electrically connected.

[0043] A processing method for a light-emitting device includes:

[0044] Step 1: Prepare two support portions and N flexible light strips. A connecting portion is fixedly provided on one support portion. Fix the two ends of the flexible light strip to the two support portions respectively, or directly integrally form the two support portions and the N flexible light strips.

[0045] Step 2: Fix the two support portions to the stem. The distance between the two support portions is smaller than the length of the flexible light strip. Mount the flexible light strip on the connecting portion so that the flexible light strip surrounds the two support portions.

[0046] In the technical solution of the present invention, first, the support part and the flexible light strip are connected into a whole, or directly integrally formed. Then, it is assembled on the core column, and the flexible light strip is hung on the connecting part to form a spiral, arc or other shaped light-emitting device around the support part. Firstly, it can realize automatic production, greatly improve production efficiency, reduce labor costs and manufacturing costs. Secondly, the whole can be designed modularly. By different mounting heights, such as in Embodiment 1 and Embodiment 2, it can be assembled into an arc, spiral or other structures. That is, the arc, spiral or other structures can share the above whole. Thirdly, it can ensure the multi-level uniform light emission of the flexible filament lamp, with the characteristics of large angle and high luminous efficiency. In the technical solution of the present invention, the flexible light strip adopts the "panel splicing" method to divide the conventional long filament into several short light strips and arrange them in parallel. The length of the light strip depends on the size of the formed spiral (or circular) diameter. This is beneficial for the existing bracket to pre-fix the light strip, greatly reducing the number of spot welds and facilitating the shaping of the arc, spiral or other structures of the flexible light strip, and can ensure a perfect light output effect. Moreover, the support part not only plays a role in supporting and fixing but also plays a role in conductive connection, simplifying the structure.

[0047] Embodiment 2

[0048] Please refer to Figure 6 , the difference from Embodiment 1 is that the two support parts 1, 1' are arranged staggered up and down, and the N flexible light strips 2 surround the two support parts 1, 1' and form an up-and-down spiral structure. According to needs, the two support parts 1, 1' are inclined and staggered up and down, and the lengths of the N flexible light strips 2 are designed to be unequal, then a conical thread structure can be designed.

[0049] Embodiment 3

[0050] Please refer to Figure 7 and Figure 8 , the difference from Embodiment 1 is that a plurality of second protruding parts 12 are fixedly arranged on the first support part 11 at uniform intervals along the height of the support part. The N first protruding parts 11 and the N second protruding parts 12 are respectively arranged staggered up and down on both sides of the first support part 11, so that the N flexible light strips are fixedly connected to the fixed positions of the first support part and the N connecting parts are arranged staggered up and down one by one. The two support parts 1, 1' are arranged at the same height, and the N flexible light strips 2 surround the two support parts 1, 1' and form a spiral structure. According to needs, they can also be arranged at different heights. By setting appropriate heights, the N flexible light strips 2 can surround the two support parts 1, 1' and form an arc structure with a central angle greater than 180 degrees.

[0051] Embodiment 4

[0052] Please refer to Figure 9 and Figure 10, the difference from the third embodiment is as follows: the first support portion 1 has a wide plate-like structure, the flexible light strip 2 is directly fixed to the inner side of the first support portion 1, the second protruding portion 12 as described above protrudes from the outer side of the first support portion 11, and the connecting portion 13 as described above is provided at the end of the second protruding portion 12. The second support portion 1' has a narrow plate-like structure, and the flexible light strip 2 is directly fixed to the inner side of the second support portion 1'. The fixing positions of the N flexible light strips fixed to the first support portion and the N connecting portions are arranged in a staggered manner up and down one by one. The two support portions 1 and 1' are arranged at the same height, and the N flexible light strips 2 surround the two support portions 1 and 1' and form a spiral structure. The first support portion 1 and the second support portion 1' have a plate-like structure, which not only plays a role in conducting electricity and fixing, but also can play a role in heat dissipation.

[0053] As described above, it is only a preferred embodiment of the invention, so the scope of implementation of the invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the invention patent and the content of the specification should still fall within the scope covered by the invention.
