Description

Technical Field

[0001] This utility model relates to the field of flexible LED filament technology, specifically a segmentable flexible LED filament structure. Background Technology

[0002] Flexible LED filament is an emerging LED lighting technology that uses a flexible substrate material to encapsulate multiple tiny LED chips in a linear manner, forming a light-emitting body similar to a traditional incandescent filament. Its core lies in the word "flexible," which determines its characteristics that are completely different from traditional LED light sources.

[0003] In existing flexible LED filament structures, the length of the LED filament cannot usually be adjusted. The only way to meet the requirements is to replace the filament with one of different lengths. This limitation reduces the applicability of the LED filament and thus affects its performance. To address this, we propose a segmentable flexible LED filament structure. Utility Model Content

[0004] The purpose of this invention is to provide a segmentable flexible LED filament structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a segmentable flexible LED filament structure, comprising two flexible shells, a flexible circuit board disposed between the inner walls of the two flexible shells, multiple LED chips disposed on the top of the two flexible circuit boards, a first sealing head and a second sealing head respectively disposed at both ends of the two flexible shells, a first connecting piece and a second connecting piece respectively disposed on the top of the two flexible circuit boards, the two first connecting pieces passing through the two first sealing heads respectively, the two second connecting pieces passing through the two second sealing heads respectively, a snap-fit ​​outer shell disposed between the two second sealing heads, a snap-fit ​​structure disposed inside the snap-fit ​​outer shell for locking the two second connecting pieces, and a first positioning plate fixedly connected to the outer side of the two first sealing heads.

[0006] As a further preferred embodiment of this technical solution, a guide plate is fixedly connected between the inner walls of the snap-fit ​​housing, and the top of the guide plate abuts against two second connecting plates.

[0007] As a further preferred embodiment of this technical solution, two second positioning plates are fixedly connected to the outer sides of the two second sealing heads, and four limiting blocks are fixedly connected to the outer side of the snap-fit ​​housing.

[0008] As a further preferred embodiment of this technical solution, each of the four limiting blocks has a positioning groove on one side, the four positioning grooves respectively penetrate the four limiting blocks, and the outer sides of the four second positioning plates respectively contact the inner sides of the four positioning grooves.

[0009] As a further preferred embodiment of this technical solution, the snap-fit ​​structure includes a threaded rod, which is threadedly connected to the top of the inner side of the snap-fit ​​housing. The top end of the threaded rod extends to the top of the snap-fit ​​housing, and the bottom end of the threaded rod is rotatably connected to a snap-fit ​​plate.

[0010] As a further preferred embodiment of this technical solution, a rotating wheel is rotatably connected to the top of the snap-fit ​​housing, and the bottom end of the rotating wheel extends into the interior of the snap-fit ​​housing and is fixedly connected to the threaded rod.

[0011] This invention provides a segmentable flexible LED filament structure, which has the following advantages:

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, a segmentable flexible LED filament structure includes two flexible housings 1. A flexible circuit board 11 is disposed between the inner walls of each of the two flexible housings 1. Multiple LED chips 12 are disposed on the top of each of the two flexible circuit boards 11. A first sealing head 3 and a second sealing head 7 are respectively disposed at both ends of each of the two flexible housings 1. A first connecting piece 6 and a second connecting piece 15 are respectively disposed on the top of each of the two flexible circuit boards 11. The two first connecting pieces 6 pass through the two first sealing heads 3, and the two second connecting pieces 15 pass through the two second sealing heads 7. A snap-fit ​​connector is disposed between the two second sealing heads 7. The shell 2 has a snap-fit ​​structure inside, which is used to snap the two second connecting pieces 15. The outer sides of the two first sealing heads 3 are fixedly connected to the first positioning plates 4. The inner walls of the snap-fit ​​shell 2 are fixedly connected to the guide pieces 13, and the top of the guide pieces 13 abuts against the two second connecting pieces 15. The outer sides of the two second sealing heads 7 are fixedly connected to the two second positioning plates 8. The outer sides of the snap-fit ​​shell 2 are fixedly connected to the four limiting blocks 9. The four limiting blocks 9 have positioning grooves 5 on one side, and the four positioning grooves 5 pass through the four limiting blocks 9 respectively. The outer sides of the four second positioning plates 8 contact the inner sides of the four positioning grooves 5 respectively.

[0021] When using the flexible LED filament structure, firstly, four second positioning plates 8 are inserted into the positioning slots 5 on the four limiting blocks 9, so that the two second connecting pieces 15 (specifically made of tin-plated copper material to ensure the solderability and conductivity of the second connecting pieces 15) enter the interior of the snap-fit ​​housing 2. Next, the two second connecting pieces 15 are tightly fixed to the guide piece 13 (specifically made of tin-plated copper material) through the snap-fit ​​structure. Then, the two first connecting pieces 6 (specifically made of tin-plated copper material to ensure the solderability and conductivity of the first connecting pieces 6) are connected to the external power supply, so that the two flexible circuit boards 11 (specifically made of polyimide material) are connected to the external power supply. The LED filament is made of aluminum, which ensures both the sealing and protection of the LED filament and the thermal conductivity of the LED filament structure. The two first sealing heads 3 (made of aluminum, which ensures both the sealing and protection of the LED filament and the thermal conductivity of the LED filament structure) and two second sealing heads 7 (made of aluminum) respectively seal and protect the interior of the two flexible shells 1 (made of silicone). At the same time, the conductivity of the conductor 13 ensures the normal use of two or more flexible LED filaments. The four first positioning plates 4 facilitate the connection and segmentation of two or more flexible LED filament structures.

[0022] According to the requirements for using LED filaments, when the LED filaments are too long, the fixing of the two second connecting pieces 15 is released through the snap-fit ​​structure. Then, the excess LED filaments are pulled out and the snap-fit ​​housing 2 is disassembled. This allows for the segmented use of the flexible LED filament structure, thereby improving the performance of the flexible LED filament structure.

[0023] like Figures 1-4 As shown, the snap-fit ​​structure includes a threaded rod 16, which is threadedly connected to the top of the inner side of the snap-fit ​​housing 2. The top end of the threaded rod 16 extends to the top of the snap-fit ​​housing 2, and the bottom end of the threaded rod 16 is rotatably connected to a snap-fit ​​plate 14. The bottom of the snap-fit ​​plate 14 abuts against two second connecting pieces 15. The top of the snap-fit ​​housing 2 is rotatably connected to a rotating wheel 10, and the bottom end of the rotating wheel 10 extends into the interior of the snap-fit ​​housing 2 and is fixedly connected to the threaded rod 16.

[0024] By rotating the wheel 10, the threaded rod 16 is driven to rotate between the inner walls of the snap-fit ​​housing 2, and the snap-fit ​​plate 14 is driven to move between the inner walls of the snap-fit ​​housing 2, thereby fixing or loosening the two second connecting pieces 15, thus improving the stability of the flexible LED filament structure.

[0025] This utility model provides a segmentable flexible LED filament structure. The specific working principle is as follows: When using the flexible LED filament structure, firstly, four second positioning plates 8 are inserted into the positioning grooves 5 on four limiting blocks 9, so that two second connecting pieces 15 enter the inner side of the snap-fit ​​shell 2. Then, by rotating the rotating wheel 10, the threaded rod 16 is driven to rotate between the inner walls of the snap-fit ​​shell 2, and the snap-fit ​​plate 14 is driven to move between the inner walls of the snap-fit ​​shell 2, thereby firmly fixing the two second connecting pieces 15 to the guide piece 13. Subsequently, the two first connecting pieces 6 are connected to the external power supply, so that the two flexible circuit boards 11 send electrical signals to the LED chip 12, and the LED chip 12 is powered on and emits light. Then, the interior of the two flexible shells 1 is sealed and protected by the two first sealing heads 3 and the two second sealing heads 7 respectively. At the same time, under the conductive effect of the guide piece 13, the normal use of two or more flexible LED filaments is ensured. The four first positioning plates 4 facilitate the connection and segmentation of two or more flexible LED filament structures.

[0026] According to the requirements for using LED filaments, when the LED filament is too long, the rotating wheel 10 is rotated to drive the threaded rod 16 to rotate between the inner walls of the snap-fit ​​housing 2, and drive the snap-fit ​​plate 14 to move between the inner walls of the snap-fit ​​housing 2, thereby releasing the fixation of the two second connecting pieces 15. Then the excess LED filament is pulled out and the snap-fit ​​housing 2 is disassembled, thus completing the use of the flexible LED filament structure.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
