Problems solved by technology

[0002] The end caps of existing lighting fixtures are connected to the lamp tubes by using glue to directly fix the end caps on the ends of the lamp tubes. Although this method has a good sealing effect, it is inconvenient for maintenance, and some need to use destructive means to fix the end caps. If it is disassembled, the entire lighting fixture may be damaged, resulting in waste of resources and increased maintenance costs

Embodiment Construction

[0021] Such as figure 1 and figure 2 The illustrated lighting fixture includes a lamp tube 1 and an end cover 2 , and a sealing ring 3 is provided between the lamp tube 1 and the end cover 2 .

[0022] Such as Figure 4 As shown, the sealing ring 3 is provided with a U-shaped groove, the U-shaped groove is set on the end of the lamp tube 1 and wraps the inner and outer walls of the lamp tube 1, and the end cap 2 is also provided with a groove. The groove in 2 wraps sealing ring 3. Such as Figure 5 and Figure 6 The sealing ring 3 shown is provided with an annular protrusion 31 on one side of the outer wall of the lamp tube 1, the annular protrusion 31 can prevent the sealing ring from falling off from the lamp tube 1, and at the same time ensure the sealing effect between the sealing ring 3 and the end cover 2 Even better, the connection of the end cover 2 is more firm and difficult to fall off. The material of the sealing ring 3 is silica gel, which is an elastic mate...
