[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-Figure 3 This LED lamp tube includes a lampshade 1 and a plug 2 connected to the end of the lampshade 1. The lampshade 1 and the plug 2 are respectively formed by plastic materials. The plug 2 is provided with a connecting portion 21 extending toward the lampshade 1. The connecting portion 21 is tightly connected to the lampshade 1. The material cost of the plug 2 is relatively low, which is conducive to improving the cost-effectiveness of the product and achieving a better overall lightweight effect of the product.

[0023] Furthermore, the lampshade 2 is in the shape of a polygonal column, and is provided with a light-emitting surface and a light-blocking surface, so that the lamp tube can have a one-sided or multi-sided light-emitting effect. Multi-sided light-emitting can make the light-emitting effect uniform and without light spots.

[0024] Furthermore, the connecting portion 21 is fixed to the inner wall of the lampshade 1 by ultrasonic welding. After the lampshade 1 and the plug 2 are installed, the connecting portion 21 will not leak out and affect the appearance of the product. At the same time, ultrasonic welding can further improve the connection strength between the lampshade 1 and the plug 2, and at the same time make the sealing of the connection position between the two better.

[0025] Furthermore, a plurality of convex ribs 22 are provided on the connecting portion 21, and the convex ribs 22 are distributed along the circumference of the connecting portion 21. The convex ribs 22 can further enhance the connection strength between the lampshade 1 and the plug 2. When ultrasonic welding is adopted, the convex ribs 22 can be partially melted, thereby making the ultrasonic welding effect of the connecting portion 21 and the lampshade 1 better.

[0026] Furthermore, a light strip mounting portion 11 for fixing the light strip is provided on the inner side of the lampshade 1 . The light strip mounting portion 11 is integrally formed with the lampshade 1 , making it convenient to install the light strip inside the lampshade 1 .

[0027] Furthermore, the connecting portion 21 includes a first welding block 211 and a second welding block 212, and an insertion gap 213 corresponding to the light strip mounting portion 11 is formed between the first welding block 211 and the second welding block 212. The light strip mounting portion 11 extends into the insertion gap 213 and fits tightly with the first welding block 211 and the second welding block 212 respectively. The first welding block 211 and the second welding block 212 can improve the structural strength of the light strip mounting portion 11.

[0028] Furthermore, the connecting portion 21 includes two second welding blocks 212, and the first welding block 211 and the two second welding blocks 212 respectively form corresponding plug-in gaps 213, and the upper and lower sides of the light strip mounting portion 11 are respectively connected and cooperated with the corresponding plug-in gaps 213, further improving the structural strength of the light strip mounting portion 11.

[0029] Furthermore, a connecting rib 214 is provided between the second welding blocks 212, and the head and tail ends of the connecting rib 214 are respectively integrally formed with the two second welding blocks 212, and the middle section of the connecting rib 214 is tightly matched with the inner wall of the lampshade 1, which can make the structure between the two second welding blocks 212 more stable, and at the same time increase the connection area between the connecting part 21 and the lampshade 1 as a whole, thereby further improving the connection strength between the lampshade 1 and the plug 2.

[0030] Furthermore, the plug 2 is provided with a mounting portion 23 extending outward, and the mounting portion 23 is in the shape of a boss. The mounting portion 23 can facilitate the installation and fixation of the product to both sides of the cabinet or other external equipment. The relative thickening of the mounting portion 23 can increase the overall structural strength, reduce the chance of damage when the plug 2 is installed and fixed to the external equipment, and is not prone to accidental falling off.

[0031] Furthermore, the mounting portion 23 is provided with a screw countersunk hole 231 corresponding to the screw device.

[0032] The above embodiments are only preferred embodiments of the present invention, and other embodiments are possible. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope set by the claims of this application.
