Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] like Figures 1 to 7 As shown, the LED tube provided in the embodiments of this application includes an LED light source 10, a driver circuit board 20, a tube body 30, a sealing sleeve 50, and two end cap structures 40. The tube body 30 has a through-cavity 31, in which the LED light source 10 is disposed, and the driver circuit board 20 is electrically connected to the LED light source 10. The two end cap structures 40 are respectively connected to both ends of the tube body 30. The end cap structure 40 includes a cover assembly 41 and a solid electrode terminal 42. The end of the tube body 30 is inserted into the cover assembly 41, and the electrode terminal 42 passes through the cover assembly 41 and is sealed and assembled with the cover assembly 41. The two ends of the LED light source 10 are respectively connected to the two end cap structures 40. The driver circuit board 20 is installed inside the end cap structure 40 and is electrically connected to the electrode terminal 42. The sealing sleeve 50 is fitted onto the end of the tube body 30, and the sealing sleeve 50 is clamped between the end of the tube body 30 and the cover assembly 41 to seal the gap between the end of the tube body 30 and the cover assembly 41.

[0047] When using the LED tube provided in the embodiments of this application for lighting, the end cap structure 40 of the LED tube adopts a solid electrode terminal 42, which is sealed and assembled on the cover assembly 41. Furthermore, the cover assembly 41 and the end of the tube body 30 are sealed together by a sealing sleeve 50, thereby forming a good sealing effect on the LED light source 10 in the through cavity 31 of the tube body 30 and the driving circuit board 20 in the cover assembly 41. Thus, even if the LED tube provided in the embodiments of this application is applied to water- and dusty application scenarios such as supermarket refrigerated display case lighting or roadside billboard lighting, it can still meet the requirements for good waterproof and dustproof effects, improving the adaptability of the LED tube in different water- and dusty lighting scenarios.

[0048] like Figure 2 , Figures 4 to 7 As shown, the cover assembly 41 includes a first cover 411 and a second cover 412. The second cover 412 is rotatably connected to the end of the first cover 411 away from the tube body 30, thus forming the cover assembly 41. Furthermore, the end cap structure 40 also includes a sealing ring 43, which is disposed between the first cover 411 and the second cover 412 to seal the gap between them, ensuring good waterproof and dustproof performance between the assembled first cover 411 and second cover 412. The end of the tube 30 is inserted into the first cover 411, the drive circuit board 20 is installed inside the first cover 411, the electrode terminal 42 passes through the second cover 412 and is sealed and assembled with the second cover 412, and the sealing sleeve 50 is clamped between the end of the tube 30 and the first cover 411 to seal the gap between the end of the tube 30 and the first cover 411, so that the assembled tube 30 and the first cover 411 have good waterproof and dustproof effects.

[0049] In the embodiments of this application, an LED tube is provided in which electrode terminals 42 are embedded in a second cover 412 to form a sealed assembly, and both ends of the electrode terminals 42 protrude from both sides of the second cover 412. Specifically, the LED tube uses a coating injection molding process to injection mold an integral structure of the second cover 412 and the electrode terminals 42, as shown below. Figure 2 , Figure 3 , Figure 5 and Figure 12 As shown. During the overmolding injection molding process, the solid electrode terminal 42 is placed and fixed inside the mold cavity. Then, molten plastic is poured into the mold cavity, ensuring that both ends of the electrode terminal 42 extend outside the mold cavity. After the molten plastic cools and solidifies to form the second cover 412, the electrode terminal 42 is embedded and fixed on the second cover 412, making the electrode terminal 42 and the second cover 412 a single integrated structure, as shown. Figure 2 , Figure 3 , Figure 5 and Figure 12 As shown, the electrode terminal 42 and the second cover 412 are configured in a non-perforated manner. Compared with the perforated configuration structure in related technologies where the electrode terminal 42 passes through a pre-drilled hole in the second cover 412, the non-perforated configuration structure of the electrode terminal 42 and the second cover 412 in this embodiment is more stable and reliable, and has better sealing performance and better waterproof and dustproof effect.

[0050] In order to quickly and accurately connect the end of the tube 30 to the first cover 411, such as Figures 4 to 7 , Figure 10 and Figure 11 As shown, the first cover 411 includes an outer sleeve 401 and an inner sleeve 402, with an insertion groove 403 formed between the outer sleeve 401 and the inner sleeve 402. The end of the tube 30 is inserted into the insertion groove 403. Thus, the insertion groove 403 positions the end of the tube 30, allowing it to be quickly and accurately inserted into the first cover 411, improving assembly efficiency. Furthermore, a sealing sleeve 50 is provided between the outer wall of the end of the tube 30 and the inner wall of the outer sleeve 401. The sealing sleeve 50 is clamped and pressed between the outer wall of the end of the tube 30 and the inner wall of the outer sleeve 401, providing good waterproof and dustproof performance between the end of the tube 30 and the outer sleeve 401. Further, to further improve the waterproof and dustproof performance between the end of the tube 30 and the first cover 411, such as... Figure 2 , Figures 4 to 7 As shown, the LED tube also includes an O-ring 60, which is accommodated in the insertion groove 403, and the end of the tube body 30 abuts against the O-ring 60 to form a seal. Thus, by providing a sealing sleeve 50 and an O-ring 60 between the end of the tube body 30 and the first cover 411, a double waterproof and dustproof effect is achieved, making the waterproof and dustproof effect between the end of the tube body 30 and the first cover 411 more stable and reliable.

[0051] like Figure 2 , Figures 5 to 7 , Figures 10 to 13As shown, the end cap structure 40 also includes a first screw 44, a helical spring 45, and a sealing cap 46. Specifically, the first cap 411 has a threaded hole 413, and the second cap 412 has a through hole 414. The first screw 44 passes through the through hole 414 and is screwed into the threaded hole 413. The helical spring 45 is sleeved on the first screw 44, with its first end abutting against the inner wall of the through hole 414 and its second end abutting against the head of the first screw 44. The sealing cap 46 seals the port of the through hole 414 away from the threaded hole 413. In this way, the elasticity of the helical spring 45 ensures that the first cap 411 and the second cap 412 are always tightly connected and clamp the sealing ring 43, guaranteeing good waterproof and dustproof performance between the first cap 411 and the second cap 412. Furthermore, when it is necessary to adjust the relative position of the second cover 412 with respect to the first cover 411 so that the electrode terminal 42 can be adapted to the fixed external socket, the user can rotate the second cover 412 relative to the first cover 411 to adjust the insertion state of the electrode terminal 42 so that it can be adapted to the fixed external socket. The operation is simple and convenient.

[0052] To prevent the second cover 412 from rotating freely relative to the first cover 411 due to external forces, such as... Figure 2 , Figure 9 and Figure 10 As shown, one of the first cover 411 and the second cover 412 is provided with a plurality of limiting grooves 415, which are circumferentially spaced around the axis of the LED tube. Correspondingly, the other of the first cover 411 and the second cover 412 is provided with at least one limiting tooth 416, such as... Figure 13As shown. Under the elastic force of the helical spring 45, the limiting tooth 416 is separably inserted into the limiting groove 415, thereby restricting the relative position of the first cover 411 and the second cover 412, effectively preventing the second cover 412 from rotating arbitrarily relative to the first cover 411. When it is necessary to adjust the relative position of the second cover 412 relative to the first cover 411 so that the electrode terminal 42 can be adapted to the fixed external socket, the user can pull the second cover 412 along the axis of the LED tube, causing the limiting tooth 416 to disengage from the limiting groove 415, and the helical spring 45 to be further compressed. Then, the user can rotate the second cover 412 relative to the first cover 411 to adjust the insertion state of the electrode terminal 42 so that it can be adapted to the fixed external socket. When the user releases the second cover 412, the second cover 412 moves towards the first cover 411 under the elastic force of the coil spring 45, so that the limiting tooth 416 is inserted into the other corresponding limiting groove 415 again, thereby restricting the relative position of the first cover 411 and the second cover 412 again, effectively preventing the second cover 412 from rotating arbitrarily relative to the first cover 411.

[0053] In some embodiments of the LED tube provided in this application, the driver circuit board 20 is provided with a connecting lead 21, which is soldered to the electrode terminal 42, making the connection between the connecting lead 21 and the electrode terminal 42 stable and reliable. Alternatively, in some other embodiments of the LED tube provided in this application, the end cap structure 40 further includes an adapter 47 and a second screw 48. The connecting lead 21 is electrically connected to the adapter 47, and the adapter 47 is locked to the electrode terminal 42 by the second screw 48. This not only makes the connection between the connecting lead 21 and the electrode terminal 42 stable and reliable, but also allows the connecting lead 21 and the electrode terminal 42 to be disassembled and separated by removing the second screw 48, thereby facilitating subsequent maintenance of the LED tube.

[0054] When assembling the drive circuit board 20 onto the first cover 411, in order to quickly and accurately complete the installation of the drive circuit board 20, such as... Figure 10 and Figure 11 As shown, the first cover 411 is provided with a snap-fit ​​part 417, to which the drive circuit board 20 is detachably snapped. That is, the snap-fit ​​part 417 positions the drive circuit board 20, thereby enabling quick and accurate installation of the drive circuit board 20. Furthermore, under the positioning constraint of the snap-fit ​​part 417 of the first cover 411, the assembly position of the drive circuit board 20 relative to the first cover 411 remains stable and reliable.

[0055] like Figure 2 , Figures 6 to 8As shown, the LED light source 10 includes a mounting plate 11, an LED light strip 12, and connecting screws 13, with the LED light strip 12 fixedly connected to the mounting plate 11. Figure 2 As shown, the inner wall of the tube body 30 is provided with two opposing mounting slide rails 32, and, as Figure 8 As shown, mounting plate 11 has mounting grooves 112 on both sides, which are adapted to the mounting slide rail 32 for quick and accurate assembly of the LED light source 10 into the tube body 30, improving assembly efficiency. Furthermore, the first cover 411 has a first limiting part 419, and the end of the mounting plate 11 has a second limiting part 111, which is adapted to the first limiting part 419. Thus, when connecting the first cover 411 to the end of the tube body 30, the mounting plate 11 and the first cover 411 are quickly positioned through the first limiting part 419 and the second limiting part 111, thereby completing the assembly quickly and accurately, improving assembly efficiency. Further, as... Figure 9 and Figure 11 As shown, the first cover 411 is provided with a connecting hole 418, corresponding to... Figure 8 As shown, the mounting plate 11 is provided with screw mounting holes 113 corresponding to the connecting hole 418. The connecting screw 13 passes through the connecting hole 418 and is screwed and locked to the screw mounting hole 113 at the end of the mounting plate 11. This ensures that the LED light source 10 remains stable inside the tube 30 and that the LED light source 10 does not shake inside the tube 30.
