[0039] Preferably, from Figure 1 and Figure 2As can be seen, the lampshade 1 is provided with a plurality of grooves 6, and the base 4 is provided with a plurality of protruding portions 7, the shape and size of the protruding portions 7 being matched with the grooves 6 on the lampshade 1.

[0040] The quick assembly and disassembly of the lamp tube can be realized through the concave-convex matching mode, and the loosening can be avoided during the connection process, thereby improving the stability of the connection.

[0041] Preferably, the lampshade 1 is provided with a plurality of hooked components 8, and the base 4 is provided with a plurality of grooves 9, the depth and shape of the grooves 9 of the base 4 being adapted to the hooked components 8 on the surface of the lampshade 1, so as to realize the stable buckling.

[0042] In the present application, the hooked components 8 of the lampshade 1 are inserted into the grooves 9 of the base 4, and the buckle connection is realized through a certain pressure, thereby forming a reliable buckle clamping effect, which can further improve the reliability of the connection, simplify the assembly process, and reduce the tools and time required in the traditional connection mode; meanwhile, the structure also has good wear resistance and is suitable for use in various complex environments.

[0043] Preferably, the lampshade 1 is made of white transparent material, which is used for irradiating the light treated by the LED light source module 2 to the outside.

[0044] The lampshade 1 is set to be white and transparent, which not only can make the light source generated by the LED light source module 2 irradiate to the outside, but also can enhance the light reflection of the white part, so that the light is brighter and more uniform, thereby improving the user experience.
