Description

Technical Field

[0001] This utility model relates to the field of LED tube technology, and in particular to an LED tube that can be spliced ​​into various shapes. Background Technology

[0002] LEDs (Light Emitting Diodes), as the fourth generation of lighting sources, offer significant advantages in energy saving and lifespan. With societal development, energy consumption in daily lighting has become increasingly prominent, making LED tubes, with their significant energy-saving advantages, increasingly popular. Longer LED tubes are typically chosen for longer advertising light boxes, shopping mall display cases, and factories to provide more even product illumination. However, in the LED tube manufacturing industry, standard LED tubes are generally not very long for ease of transportation and storage. Therefore, to address these issues, splicable LED tubes have emerged on the market.

[0003] A search revealed that Chinese utility model patent CN202221137007.4 discloses a splicing LED tube, comprising a tube body, an LED strip disposed inside the tube body, and a mounting base slidably disposed at the bottom of the tube body. The bottom of the tube body is provided with a splicing assembly for splicing the tube bodies. The splicing assembly includes a splicing seat slidably disposed at the bottom of the tube body and splicing fixing screws disposed on the splicing seat for fixing the splicing seat to the tube body. This LED tube can be used both as a single tube and in spliced ​​configurations. When spliced, it not only provides a secure connection but also does not obstruct the light source, resulting in better lighting performance. Furthermore, its structure is simpler and splicing is straightforward.

[0004] For example, Chinese utility model patent application number CN202322466233.8 discloses a splicable LED tube, belonging to the field of LED lighting. It includes an LED tube body and a lamp holder. The lamp holder has an interface, a threaded portion, and a mating hole. The LED tube body is inserted into the mating hole and connected to the lamp holder. A first connecting ring is connected to the outer end of the lamp holder, and an arc-shaped cover is connected to the end of the first connecting ring. A second connecting ring is connected to the other end of the arc-shaped cover. All three connecting rings—the first, the arc-shaped cover, and the second—have mounting holes. The connecting rings are installed on the lamp holder of the LED tube. The first connecting ring connects to the second connecting ring via the arc-shaped cover. Both the first and second connecting rings are threaded to the lamp holder, facilitating quick installation. The arc-shaped cover has notches to facilitate interface wiring or the installation of interface components. Reserved space is created at the connection point of two LED tubes, allowing users to customize the installation according to their needs. The array of through holes on the arc-shaped cover also allows for the use of cable ties to organize the wires.

[0005] While existing LED tubes can meet basic splicing requirements, their assembly is often cumbersome and prone to loosening, reducing their ease of use. Furthermore, components may detach from the lampshade during use; and overheating can significantly shorten their lifespan. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an LED tube that can be spliced ​​into various shapes, in view of the above-mentioned defects of the prior art.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] An LED tube with modular design includes a lampshade body. Fixing screws are installed on the surfaces of both ends of the lampshade body. Assembly components are provided on both sides of the lampshade body. The surfaces of the assembly components and the fixing screws are threaded together. A splicing component is installed on the bottom surface of each assembly component. A rapid heat dissipation mechanism is provided on the inner wall of each assembly component. This rapid heat dissipation mechanism consists of fastening bolts, heat dissipation fins, and a rapid heat dissipation part. An assembly anti-detachment mechanism is provided on the surfaces of the assembly components and the fixing screws. This assembly anti-detachment mechanism consists of an anti-detachment clip, an arc-shaped groove, and an assembly anti-detachment part.

[0009] Preferably, a light diffusion plate for increasing light intensity is adhered to the inner wall of the lampshade body, an LED bead plate is installed inside the lampshade body, a connecting piece is installed on the surface of the assembly, and a wire is installed on the surface of the connecting piece.

[0010] Preferably, the rapid heat dissipation part is disposed inside the assembly, and the lampshade body dissipates heat rapidly through the rapid heat dissipation part inside the assembly. The rapid heat dissipation part is composed of a mounting plate, a mesh plate, a heat-conducting plate, and heat dissipation holes. The inner wall of the assembly is equipped with a heat-conducting plate for guiding light, and the inner wall of the assembly is provided with heat dissipation fins for heat dissipation. The surface of the heat dissipation fins is equipped with a mounting plate, and the surface of the mounting plate is in contact with the inner wall of the assembly.

[0011] Preferably, the surface of the mounting plate is threaded with fastening bolts for fixing the mounting plate to the inner wall of the assembly. One end of the fastening bolt passes through the mounting plate and is threaded to the inner wall of the assembly. The surface of the assembly is provided with equally spaced heat dissipation holes. The heat dissipation holes are connected to the interior of the assembly. The inner wall of the heat dissipation holes is inlaid with a mesh plate for filtering impurities in the air.

[0012] Preferably, the anti-detachment assembly is disposed on the surface of the lampshade body and the inner wall of the assembly. The connection between the lampshade body and the assembly is reinforced by the anti-detachment assembly. The anti-detachment assembly includes an arc-shaped locking block, a tension spring and a groove. The surface of the fixing screw is equipped with anti-detachment locking components for preventing detachment. The inner wall of the assembly is provided with grooves for preventing detachment.

[0013] Preferably, the anti-detachment clip is engaged with the surface of the groove, the surface of the lampshade body is provided with a groove, the inside of the groove is provided with an arc-shaped clip, the arc-shaped clip is engaged with the inner wall of the groove, the inner wall of the assembly is provided with an arc-shaped groove, the arc-shaped groove is engaged with the surface of the arc-shaped clip, and the inside of the groove is provided with a tension spring, one end of the tension spring is fixed to the surface of the arc-shaped clip.

[0014] By adopting the above technical solution, the modular LED tube provided by this utility model has the following beneficial effects:

[0015] 1. An assembly anti-detachment mechanism is provided. The fixing screw drives the anti-detachment clip to lock onto the inner wall of the assembly. Under the action of the anti-detachment clip, the fixing screw is prevented from loosening on the inner wall of the assembly. When the assembly stops rotating, the elastic force of the extension spring inside the groove drives the arc-shaped clip to lock into the arc-shaped groove. The locking action of the arc-shaped clip and the arc-shaped groove reinforces the connection between the lamp cover body and the assembly, preventing the assembly from loosening on the surface of the lamp cover body. When it is necessary to remove the assembly from the surface of the lamp cover body, the elastic force of the extension spring drives the arc-shaped clip to move into the groove. At this time, the arc-shaped clip moves away from the surface of the arc-shaped groove, realizing the function of quick assembly and anti-detachment of the LED tube to the lamp cover body, thereby improving the convenience of using the LED tube and preventing the assembly from falling off the surface of the lamp cover body during the use of the LED tube.

[0016] 2. By incorporating a rapid heat dissipation mechanism, the heat dissipation fins drive the mounting plate to contact the inner wall of the assembly. Tightening the fastening bolts on the mounting plate, the heat dissipation fins are positioned against the inner wall of the assembly, dissipating heat from the lampshade body. The heat-conducting plate then conducts heat away from the lampshade body. The combined action of the heat-conducting plate and the heat dissipation fins allows the hot air to be quickly expelled from the assembly through the heat dissipation holes. The mesh plate filters the air, preventing dust from entering the assembly and affecting the normal operation of the lampshade body. This achieves rapid heat dissipation from the LED tube to the lampshade body, thus avoiding overheating during LED tube operation and significantly extending the lifespan of the LED tube.

In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] like Figure 1-2 As shown, the modular LED tube includes a lampshade body 1. Fixing screws 105 are installed on the surfaces of both ends of the lampshade body 1. Assembly parts 101 are provided on both sides of the lampshade body 1. The surfaces of the assembly parts 101 and the fixing screws 105 are threaded together. A splicing part 102 is installed on the surface of the bottom position of the assembly part 101. A light diffusion plate 103 for increasing light intensity is adhered to the inner wall of the lampshade body 1. An LED bead board 104 is installed inside the lampshade body 1. A connecting part 106 is installed on the surface of the assembly part 101. A wire 107 is installed on the surface of the connecting part 106.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the inner wall of assembly 101 is provided with a rapid heat dissipation mechanism 2. The rapid heat dissipation mechanism 2 consists of fastening bolts 201, heat dissipation fins 202, and a rapid heat dissipation section 203. The rapid heat dissipation section 203 is located inside assembly 101. The lampshade body 1 dissipates heat rapidly through the rapid heat dissipation section 203 inside assembly 101. The rapid heat dissipation section 203 consists of a mounting plate 2031, a mesh plate 2032, a heat-conducting plate 2033, and heat dissipation holes 2034. The inner wall of assembly 101 is equipped with a heat-conducting plate 2033 for guiding light, and the inner wall of assembly 101 is provided with heat dissipation fins 202 for heat dissipation. A mounting plate 2031 is installed on the surface of the fin 202. The surface of the mounting plate 2031 is in contact with the inner wall of the assembly 101. The surface of the mounting plate 2031 is threaded with fastening bolts 201 for fixing the mounting plate 2031 to the inner wall of the assembly 101. One end of the fastening bolt 201 passes through the mounting plate 2031 and is threadedly fastened to the inner wall of the assembly 101. The surface of the assembly 101 is provided with equally spaced heat dissipation holes 2034. The heat dissipation holes 2034 are connected to the interior of the assembly 101. The inner wall of the heat dissipation holes 2034 is inlaid with a mesh plate 2032 for filtering impurities in the air.

[0027] During implementation, the heat dissipation fins 202 drive the mounting plate 2031 to move until it contacts the inner wall of the assembly 101. The fastening bolts 201 on the surface of the mounting plate 2031 are tightened. Under the action of the fastening bolts 201, the heat dissipation fins 202 are placed on the inner wall of the assembly 101. The heat dissipation fins 202 dissipate heat from the lampshade body 1. The heat conduction plate 2033 conducts heat to the hot air generated by the lampshade body 1. Under the combined action of the heat conduction plate 2033 and the heat dissipation fins 202, the hot air is quickly discharged from the interior of the assembly 101 through the heat dissipation holes 2034. The mesh plate 2032 filters the air, preventing dust from entering the interior of the assembly 101 through the mesh plate 2032 and affecting the normal use of the lampshade body 1. This achieves the function of rapid heat dissipation of the interior of the lampshade body 1 by the LED tube.

[0028] Furthermore, such as Figure 2 and Figure 4 As shown, the surfaces of the assembly 101 and the fixing screw 105 are provided with an assembly anti-detachment mechanism 3. The assembly anti-detachment mechanism 3 consists of an anti-detachment clip 301, an arc-shaped groove 302, and an assembly anti-detachment part 303. The assembly anti-detachment part 303 is provided on the surface of the lampshade body 1 and the inner wall of the assembly 101. The connection between the lampshade body 1 and the assembly 101 is reinforced by the assembly anti-detachment part 303. The interior of the assembly anti-detachment part 303 includes an arc-shaped clip 3031, a extension spring 3032, and a groove 3033. The surfaces of the fixing screw 105 are all equipped with anti-detachment clips 301 for preventing detachment. The inner wall of 01 is provided with grooves for preventing detachment. The anti-detachment clip 301 is engaged with the surface of the groove. The surface of the lampshade body 1 is provided with grooves 3033. The inside of the grooves 3033 is provided with arc-shaped clips 3031. The arc-shaped clips 3031 slide with the inner wall of the grooves 3033. The inner wall of the assembly 101 is provided with arc-shaped grooves 302. The arc-shaped grooves 302 are engaged with the surface of the arc-shaped clips 3031. The inside of the grooves 3033 is provided with extension springs 3032. One end of the extension springs 3032 is fixed to the surface of the arc-shaped clips 3031.

[0029] During implementation, the fixing screw 105 drives the anti-detachment clip 301 to lock onto the inner wall of the assembly 101. The anti-detachment clip 301 prevents the fixing screw 105 from loosening on the inner wall of the assembly 101. When the assembly 101 stops rotating, the elastic force of the extension spring 3032 inside the groove 3033 drives the arc-shaped clip 3031 to lock onto the inside of the arc-shaped groove 302. The locking action between the arc-shaped clip 3031 and the arc-shaped groove 302 further secures the assembly. The connection between the lampshade body 1 and the assembly 101 is reinforced to prevent the assembly 101 from becoming loose on the surface of the lampshade body 1. When it is necessary to remove the assembly 101 from the surface of the lampshade body 1, the arc-shaped locking block 3031 moves into the groove 3033 under the elastic force of the extension spring 3032. At this time, the arc-shaped locking block 3031 moves away from the surface of the arc-shaped groove 302 to realize the function of quick assembly and anti-detachment of the LED tube to the lampshade body 1.

[0030] Working principle: In use, first place the lampshade body 1 in the designated position, place the assembly 101 on the surface of the lampshade body 1, rotate the assembly 101, and fix the lampshade body 1 to the surface of the assembly 101 under the thread engagement of the assembly 101 and the fixing screw 105. At this time, the fixing screw 105 drives the anti-detachment clip 301 to lock onto the inner wall of the assembly 101. Under the action of the anti-detachment clip 301, the fixing screw 105 is prevented from loosening on the inner wall of the assembly 101. When the assembly 101 stops rotating, the elastic force of the extension spring 3032 inside the groove 3033 drives the arc-shaped clip 3031 to lock into the inside of the arc-shaped groove 302. The locking action of block 3031 and arc groove 302 reinforces the connection between lamp cover body 1 and assembly 101, preventing assembly 101 from becoming loose on the surface of lamp cover body 1. When it is necessary to remove assembly 101 from the surface of lamp cover body 1, the elastic force of extension spring 3032 drives arc-shaped locking block 3031 to move into groove 3033. At this time, arc-shaped locking block 3031 moves away from the surface of arc groove 302, so as to realize the function of quick assembly and anti-detachment of LED tube to lamp cover body 1, thereby improving the convenience of LED tube use and preventing assembly 101 from falling off the surface of lamp cover body 1 during LED tube use.

[0031] Subsequently, the heat dissipation fins 202 drive the mounting plate 2031 to contact the inner wall of the assembly 101. The fastening bolts 201 on the surface of the mounting plate 2031 are tightened. Under the action of the fastening bolts 201, the heat dissipation fins 202 are placed on the inner wall of the assembly 101. The heat dissipation fins 202 dissipate heat from the lampshade body 1. The heat conduction plate 2033 conducts heat to the heat generated by the lampshade body 1. Under the combined action of the heat conduction plate 2033 and the heat dissipation fins 202, the hot air is quickly discharged from the interior of the assembly 101 through the heat dissipation holes 2034. The mesh plate 2032 filters the air, preventing dust from entering the interior of the assembly 101 through the mesh plate 2032 and affecting the normal use of the lampshade body 1. This achieves the function of rapid heat dissipation of the interior of the lampshade body 1 by the LED tube, thereby avoiding the phenomenon of excessive temperature during the use of the LED tube. At the same time, it greatly improves the service life of the LED tube, and finally completes the use of the LED tube.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
