It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0023] like Figures 1-3 As shown, an LED aluminum-plastic tube in this embodiment includes a lamp body 10 and lamp heads 20 disposed at both ends of the lamp body 10. The lamp body 10 is cylindrical and includes a lamp holder 210 and a lamp cover 220 snapped onto the lamp holder 210. Specifically, the lamp holder 210 is made of aluminum, and the lamp cover 220 is made of a light-transmitting material, such as PC material. In actual production, the aluminum in the aluminum-plastic structure of the lamp body 10 accounts for 43%, which better ensures subsequent heat dissipation while controlling production costs. The lamp holder 210 includes an arc-shaped support portion 211 and a mounting bracket disposed between the two ends of the support portion 211. The mounting part 212 is used to make the lamp holder 210 hollow, forming a heat dissipation channel. The two ends of the support part 211 form snap-fit ​​grooves 2121, which are arranged along the extension direction of the lamp holder 210. The two ends of the lamp cover 220 are snap-fitted into the corresponding snap-fit ​​grooves 2121. Specifically, the lamp cover 220 is arc-shaped, and snap-fit ​​parts are formed on both sides. The snap-fit ​​parts are arranged along the extension direction of the lamp cover 220 and snap-fit ​​into the corresponding snap-fit ​​grooves 2121, so as to realize the installation of the lamp cover 220 on the lamp holder 210 to form a cylindrical lamp body 10. The mounting part 212 is snap-fitted with a light-emitting component. The lamp holder 20 includes an end cap 200, which is installed at the end of the lamp body 10 via a plug-in assembly. A support plate 310 is provided inside the end cap 200 corresponding to the mounting part 212. The support plate 310 is used to form an upper cavity 301 and a lower cavity 302 inside the end cap 200. A heat dissipation assembly is provided between the lower cavity 302 and the lamp holder 210.

[0024] In actual use, when the end cap 200 is installed on the end of the lamp body 10 via the plug-in assembly, the support plate 310 abuts against the end wall of the corresponding mounting part 212 so that the lower cavity 302 is connected to the heat dissipation channel. The heat dissipation assembly is disposed in the lower cavity 302 and the heat dissipation channel. The heat dissipation assembly can dissipate heat from the lamp holder 210 so that the light-emitting component can be dissipated.

[0025] In this embodiment, the mounting portion 212 is provided with an inner fastening groove 2122 and reflective portions 2123 distributed on both sides of the inner fastening groove 2122. Specifically, in combination with Figure 2 As shown, the mounting portion 212 between the inner grooves 2122 is horizontally arranged, wherein the reflective portion 2123 is inclinedly arranged on both sides of the inner grooves 2122. In actual use, the surface of the reflective portion 2123 is coated with a reflective coating. The reflective coating can better reflect part of the light emitted by the light-emitting component to the lamp cover 220, thereby improving the luminous efficiency of the LED aluminum-plastic tube. The light-emitting component includes a substrate 230 disposed on a mounting portion 212 between the inner grooves 2122. The substrate 230 is disposed along the extending direction of the mounting portion 212. A plurality of LED beads 231 are arranged on the substrate 230. The light-emitting component also includes a driving power supply 320 disposed on a support plate 310 in the upper cavity 301. The driving power supply 320 is electrically connected to the substrate 230 and is used to control the LED beads 231 to emit light.

[0026] In actual use, the substrate 230 is an existing PCB board, and its two sides are slidably snapped into the corresponding inner grooves 2122 to realize the installation of the substrate 230 on the mounting part 212. like Figure 3 As shown, specifically, the driving power supply 320 has an existing structure, which includes a driving circuit board, circuit elements disposed on the driving circuit board, and pins extending through the end cover 200. The pins are connected to the driving power supply 320 by wires, thereby enabling the driving power supply 320 to control the light emission of the LED lamp bead 231.

[0027] Combination Figure 4 As shown, in this embodiment, the mounting portion 212 located between the inner grooves 2122 protrudes outward to form a plug-in plate 331, and the plug-in plate 331 is provided with a first groove 401; The plug-in assembly includes a deformation groove 501 on the support plate 310. A first buckle 510 is provided in the deformation groove 501. When the end cap 200 is plugged into the end of the lamp body 10, the first buckle 510 is engaged in the first buckle groove 401 to fix the end cap 200.

[0028] In actual use, when the end cap 200 is inserted into the end of the lamp body 10, the insertion plate 331 extends into the lower cavity 302, and at the same time, the first buckle 510 is inserted into the first buckle groove 401 to fix the end cap 200. Specifically, to prevent the upper cavity 301 and lower cavity 302 from being connected during the installation of the end cap 200, which could easily lead to dust entering the light-emitting component, in this embodiment, an abutment plate 403 is provided at the end of the mounting part 212. When the end cap 200 is inserted into the end of the lamp body 10, the end of the support plate 310 abuts against the abutment plate 403 to separate the upper cavity 301 and lower cavity 302. Specifically, to improve the sealing effect, a sealing gasket is provided on the outer side wall of the abutment plate 403.

[0029] In this embodiment, in order to further improve the installation stability of the end cap 200 at the end of the lamp body 10, the lamp cover 220 is provided with a second buckle groove, and the inner wall of the upper cavity 301 is provided with a second buckle 520. When the end cap 200 is inserted into the end of the lamp body 10, the second buckle 520 is engaged in the second buckle groove to fix the end cap 200.

[0030] In this embodiment, in order to facilitate the insertion of the end cap 200 onto the lamp body 10, so that the first buckle 510 and the first buckle groove 401, the second buckle 520 and the second buckle groove can cooperate, wherein the lower side wall of the support part 211 is provided with a sliding groove 402 along its length direction, and the inner wall of the lower cavity 302 is provided with a slider 503 that slides in the sliding groove 402.

[0032] In this embodiment, the mounting part 212 is provided with heat dissipation fins 2124 located inside the lamp holder 210 along its length direction, and the side wall of the end cover 200 is provided with heat dissipation holes 502 communicating with the lower cavity 302.

[0033] In this embodiment, multiple heat dissipation fins 2124 are arranged along the length of the lamp holder 210, and they are also made of aluminum. Therefore, the heat dissipation fins 2124 can conduct the heat generated by the substrate 230 and the LED beads 231 into the heat dissipation channel. At the same time, in conjunction with the setting of the heat dissipation hole 502, the heat dissipation channel can be connected to the outside to promote air flow and improve the heat dissipation effect of the heat dissipation component.

[0034] In this embodiment, to facilitate the maintenance and replacement of the drive power supply 320, the end of the end cap 200 away from the lamp body 10 protrudes outward to form a convex tube 410. The convex tube 410 has openings at both ends, one end of which is fixed to the side wall of the end cap 200 and connected to the upper cavity 301, so that the drive power supply 320 can be pulled out from the other end opening of the convex tube 410 for maintenance. Specifically, the outer end of the convex tube 410 is provided with a cover plate 420 by screws. The cover plate 420 has a hole for the pin to extend out. The cover plate 420 is installed and removed from the outer end of the convex tube 410 to facilitate the maintenance of the drive power supply 320.
