After the lamp tube 400 is threaded into the base 300, the annular protrusion at the upper end of the lamp tube 400 cooperates with the annular groove 601A. There is also a corresponding ring of protrusions at the contact point between the annular protrusion 400C and the annular groove 601A. The two can be tightly fitted together through the concave-convex structure, which plays a waterproof role.

[0043] In some embodiments, reference Figure 2As shown, a positioning boss 400A is formed on the outer side of the lamp tube 400, and the lower end of the base 300 is in close contact with the positioning boss 400A. A second sealing ring 800 is provided between the base 300 and the lamp tube 400 and in close contact with the positioning boss 400A. This application adopts a multi-layer waterproof structure.
