Technical Field

[0001] This utility model relates to the field of LED tubes, and in particular to an easily detachable LED tube. Background Technology

[0002] With the continuous development of lighting technology, LED tubes have been widely used in many places due to their advantages such as energy saving, high brightness and long life.

[0003] The inventors observed in daily life that traditional LED tubes are typically mounted on lamp holders with both ends fixed, for example, using clips or screws for fastening. When replacing the tubes, such as due to damage or adjustments to the lighting layout, the disassembly process is often cumbersome. For tubes secured with screws, tools are needed to unscrew each screw individually, which is time-consuming, and for tubes installed at heights, using tools increases safety risks. Furthermore, slight carelessness during disassembly can easily damage the tube itself or the lamp holder, affecting subsequent use and installation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies in terms of installation, disassembly, and heat dissipation, and to propose an easily disassembled LED tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an easily detachable LED tube, comprising a tube, an LED bead PCB board, a cap, and motor pins. The LED bead PCB board is disposed inside the tube. Both ends of the tube are fitted with caps. Motor pins are provided on the surface of the caps. The tube includes a first semi-arc plate and a second semi-arc plate. A locking block is provided on the surface of the first semi-arc plate, and a locking groove is provided on the surface of the second semi-arc plate. The locking block and the locking groove fit together. A snap-fit ​​assembly is fixedly connected to the surface of the tube. A reserved groove is provided inside the cap.

[0006] Furthermore, the snap-fit ​​assembly includes a mounting block disposed on the outer surface of the lamp tube. A spring is fixedly connected to the upper surface of the mounting block, and a pressing block is fixedly connected to the upper end of the spring. This greatly simplifies the installation and disassembly process of the lamp tube, eliminating the need for complex tools, facilitating the replacement and maintenance of the lamp tube by users, and improving operational efficiency.

[0007] Furthermore, the reserved slot includes a connecting slot, which is formed on the side surface of the end cap near the lamp tube. Sliding grooves are formed above and below the connecting slot, and a pressing groove is formed on the outer surface of the end cap, so as to realize reliable connection or easy separation between the lamp tube and the external device, thereby improving the convenience and operability of the entire operation process.

[0008] Furthermore, the outer surface of the second semi-arc plate is provided with heat dissipation holes, which are respectively located at both ends of the surface of the second semi-arc plate, thereby extending the service life of the lamp tube and ensuring that the lamp tube can provide lighting services continuously and stably.

[0009] Furthermore, the mounting blocks are fixedly connected to both ends of the surfaces of the first and second semi-arc plates, respectively, allowing them to detach smoothly from the mounting position and ensuring a stable and convenient disassembly process.

[0010] Furthermore, the second semi-circular plate has a placement plate inside, and the upper surface of the placement plate is provided with an LED lamp bead PCB board, which helps to protect the LED lamp bead PCB board from external impacts and other damage, extend its service life, and improve the overall reliability of the lamp tube.

[0011] Furthermore, the upper surface of the placement plate is provided with a fixing plate, which can effectively prevent the LED lamp bead PCB board from sliding or warping during long-term use or when subjected to large external impacts, thus ensuring the connection stability between the lamp bead and the power supply.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the lamp tube is composed of a first semi-circular plate and a second semi-circular plate, with the locking block and the locking slot fitting together. Combined with the locking components set at both ends of the outer surface of the lamp tube, the overall structure of the lamp tube is greatly simplified, while realizing convenient installation and disassembly. During installation, simply align the locking block and the locking slot, and then use the locking components to lock and fix it to the external lamp holder, etc. During disassembly, pressing the pressing block of the locking components can easily remove the lamp tube. Unlike traditional lamp tubes, there is no need to use complicated tools or go through cumbersome steps, which effectively saves installation and disassembly time. It is especially convenient for the maintenance and replacement of lamp tubes at high places, reducing the difficulty of operation and safety risks.

[0014] 2. In this invention, the performance of the lamp tube is ensured from multiple aspects, including heat dissipation and internal component fixation, by utilizing heat dissipation holes at both ends of the outer surface of the second semi-arc plate, a rationally arranged internal placement plate, and a fixing plate. The heat dissipation holes ensure good heat dissipation of the lamp tube, extending the lifespan of the LED beads; the placement plate and fixing plate ensure the stable installation of the LED bead PCB board inside the lamp tube, maintaining the stability of the lighting. These structures work together to enable the LED lamp tube of this invention to operate stably and reliably during long-term use, reducing the probability of failures caused by overheating, loose components, etc., and improving the overall quality and lifespan of the lamp tube.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an easily detachable LED tube, including a tube 1, an LED bead PCB board 2, a cap 3, and motor pins 4. The LED bead PCB board 2 is disposed inside the tube 1. Both ends of the tube 1 are equipped with caps 3. The surface of the caps 3 is provided with motor pins 4. The surface of the tube 1 is fixedly connected with a snap-fit ​​component 5. The inside of the caps 3 is provided with a reserved groove 6.

[0023] The specific settings and functions of these functions will be explained in detail below.

[0024] In this embodiment: the lamp tube 1 includes a first semi-arc plate 11 and a second semi-arc plate 12. The surface of the first semi-arc plate 11 is provided with a locking block 13, and the surface of the second semi-arc plate 12 is provided with a locking groove 14. The locking block 13 and the locking groove 14 fit together.

[0025] The aforementioned components achieve the following effect: the structural design of the first semi-circular plate 11 and the second semi-circular plate 12 makes the assembly of the lamp tube 1 more convenient. The way the locking block 13 and the locking slot 14 fit together ensures that when the first semi-circular plate 11 and the second semi-circular plate 12 are closed, they can be precisely spliced ​​together to form a complete and sealed outer shell structure for the lamp tube 1.

[0026] Specifically, the snap-fit ​​assembly 5 includes a mounting block 51, which is disposed on the outer surface of the lamp tube 1. A spring 52 is fixedly connected to the upper surface of the mounting block 51, and a pressing block 53 is fixedly connected to the upper end of the spring 52.

[0027] The effect achieved by the above components is as follows: when the lamp tube 1 needs to be installed on the external lamp holder, during the process of aligning the lamp tube 1 with the lamp holder and inserting it, the lamp holder will squeeze the pressing block 53. After the pressing block 53 is subjected to force, it moves downward against the elastic force of the spring 52. After the lamp tube 1 is inserted into the appropriate position, the pressing block 53 returns to its original position under the action of the elastic force of the spring 52 and engages with the corresponding slot or protrusion on the lamp holder, thereby realizing a stable connection between the lamp tube 1 and the lamp holder. This greatly simplifies the installation and disassembly process of the lamp tube 1, eliminates the need for additional complicated tools, and improves the convenience of installing and disassembling the lamp tube 1.

[0028] Specifically, the reserved groove 6 includes a connecting groove 61, which is opened on the side surface of the end cap 3 near the lamp tube 1. Sliding grooves 62 are opened above and below the connecting groove 61, and a pressing groove 63 is opened on the outer surface of the end cap 3.

[0029] The effect achieved by the above-mentioned components is as follows: the pressing groove 63 provides an easy-to-operate point of force for the operator. When installing or removing the lamp tube 1 from the lamp holder, pressing this point can indirectly apply force to the internal related structures, such as the linkage components that cooperate with the snap-fit ​​assembly 5, triggering the corresponding connection or separation action, making the whole operation process more convenient and controllable, and further optimizing the ease of use of the lamp tube 1.

[0030] Specifically, the outer surface of the second semi-arc plate 12 is provided with heat dissipation holes 16, which are respectively located at both ends of the surface of the second semi-arc plate 12.

[0031] The effect achieved by the above components is as follows: the heat is discharged to the external environment through the heat dissipation hole 16 located at the top, while the relatively cool air from the outside will enter the lamp tube 1 through the heat dissipation hole 16 at the bottom. This continuous air circulation can effectively remove the heat generated by the LED lamp bead PCB board 2 in a timely manner, thereby preventing problems such as performance degradation and shortened lifespan of the LED lamp beads due to overheating, extending the service life of the entire lamp tube 1, and ensuring that it can provide lighting services continuously and reliably.

[0032] Specifically, the mounting block 51 is fixedly connected to both ends of the surfaces of the first semi-arc plate 11 and the second semi-arc plate 12.

[0033] The effect achieved by the above components is that this distribution method makes the snap-fit ​​components 5 form a symmetrical and balanced layout at both ends of the lamp tube 1. When installing the lamp tube 1, the snap-fit ​​components 5 at both ends can cooperate with the corresponding mounting structure on the external lamp holder at the same time, ensuring that the lamp tube 1 is subjected to uniform fixing force in all parts in the horizontal direction, thereby improving the overall stability and reliability of the lamp tube 1 installation.

[0034] Specifically, the second semi-circular plate 12 has a placement plate 15 inside, and the upper surface of the placement plate 15 has an LED lamp bead PCB board 2.

[0035] The effect achieved by the above components is that the placement plate 15 provides a flat and stable placement surface for the LED lamp bead PCB board 2. During the assembly and daily use of the lamp tube 1, it can effectively fix the position of the LED lamp bead PCB board 2, so that it will not shift or shake due to the lamp tube 1 being transported, vibrated or subjected to other external forces.

[0036] Specifically, a fixing plate 17 is provided on the upper surface of the placement plate 15.

[0037] The aforementioned components achieve the following effect: the fixing plate 17 and the placement plate 15 cooperate with each other to further fix and limit the LED bead PCB board 2 from different directions. It can more firmly constrain the position of the LED bead PCB board 2, especially when the lamp tube 1 is used for a long time or subjected to a large external impact, it can effectively prevent the LED bead PCB board 2 from sliding, warping, loosening and other defects.

[0038] Working principle: First, the LED lamp bead PCB board 2 is placed stably on the placement plate 15 inside the second semi-arc plate 12, ensuring a tight fit with the placement plate 15. Then, the fixing plate 17 is used to fix the LED lamp bead PCB board 2, making its position on the placement plate 15 stable and preventing easy movement. Next, the first semi-arc plate 11 and the second semi-arc plate 12 are closed together, and the end caps 3 are installed at both ends of the closed lamp tube 1. During the installation process, it is necessary to ensure that the reserved groove 6 on the end cap 3 is accurately aligned with the inside of the lamp tube 1, so that the connecting groove 61 can achieve good electrical connection. The lamp tube 1 with the end caps 3 installed is then taken to the lamp holder position where it needs to be installed, and the snap-fit ​​components 5 at both ends of the outer surface of the lamp tube 1 are aligned with the corresponding installation parts on the lamp holder. Gently press the lamp tube 1 into the lamp holder. During this process, the pressing block 53 of the locking component 5 will be squeezed by the lamp holder. The pressing block 53 moves downward against the elastic force of the spring 52. When the lamp tube 1 is fully inserted into the appropriate position, the pressing block 53 returns to its original position under the elastic force of the spring 52. The pressing block 53 engages with the pre-set slots, protrusions and other structures on the lamp holder. At the same time, the motor pin 4 on the end cap 3 achieves a reliable conductive connection with the lamp holder. In this way, the lamp tube 1 is firmly installed on the lamp holder and can emit light normally.
