[0031] The light source 3 is plugged and fixed with the lampshade upper cover 1 , and the light source 3 and the lampshade upper cover 1 are arranged concentrically, and the lampshade lower cover 2 is snap-fitted and fixed with the lampshade upper cover 1 , so that the light source 3 is built inside the lampshade lower cover 2 .

[0032] Specifically, the end of the lampshade upper cover 1 facing away from the first boss 11 is convexly provided with a convex edge 14, and a positioning groove 15 is provided on the convex edge 14. The inner wall of one end of the lampshade lower cover 2 is convexly provided with a positioning block 20.
