In an embodiment of the present utility model, the lamp tube 100 includes: a lamp cover 10 provided with an insertion port 10a; a lamp panel 20 arranged in the lamp shade 10; the sealing plug 30 comprises a body 31 and a sealing flange 32 which is annularly arranged on the outer side of the body 31, the body 31 is inserted into the insertion port 10a, and the sealing flange 32 is attached to an opening of the insertion port 10a; a fitting (not shown) detachably attached to a side of the body 31 remote from the globe 10; and a sealing sleeve 50 sleeved on the outer side of the body 31, the assembly part and part of the lampshade 10, wherein the sealing sleeve 50 provides pressure to press the assembly part on the body 31, and the sealing flange 32 is pressed on the opening of the inserting port 10a.

Specifically, in the present embodiment, the lamp housing 10 is formed of a plastic material, the lamp housing 10 has a long-strip-shaped housing structure, and both ends of the lamp housing 10 are open, i.e., the insertion port 10a of the lamp housing 10. The lamp panel 20 comprises a PCB board and a plurality of lamp beads arranged on the PCB board, and the PCB board can be fixed in the lamp shade 10 by screws or a clamping structure.

The sealing plug 30 comprises a body 31 and a sealing flange 32 which are integrally formed, the sealing flange 32 is arranged in the middle of the body 31 in a surrounding mode, one end of the body 31 is inserted into the inserting port 10a, the other end of the body is used for being connected with an assembly part, the assembly part comprises an electric connector 41 and an end cover 42, the electric connector 41 and the end cover 42 are respectively arranged at two opposite ends of the lamp shade 10, the end cover 42 is used for being matched with the sealing plug 30 to seal one end of the lamp shade 10, the electric connector 41 is used for being matched with another sealing plug 30 to seal the other end of the lamp shade 10, meanwhile, the electric connector 41 is electrically connected to a PCB board through an electronic connecting wire, and the electric connector 41 is used for being connected with an external circuit to supply power to the PCB board, so that the lamp beads emit light. The sealing sleeve 50 is sleeved outside the body 31, the assembly part and the part of the lampshade 10. The sealing sleeve 50 provides pressure to press the seal against the body 31 and the sealing flange 32 against the opening of the socket 10a.

In this application, through cladding seal cover 50 in the outside of body 31, assembly part and lamp shade 10, can improve its sealing performance, seal cover 50 provides pressure simultaneously, presses assembly part towards body 31 one side, and sealing flange 32 presses towards interface 10a one side, so can reduce the assembly clearance between the three to a great extent, and the sealing performance of fluorescent tube 100 further improves. In addition, the body 31 is inserted into the lamp housing 10 and detachably connected with the assembly part, so that the lamp tube 100 is more convenient to assemble.

In one embodiment of the present application, the sealing sleeve 50 is injection molded to the outside of the body 31, fitting and part of the globe 10. Specifically, the body 31 is sleeved on the plug port 10a of the lamp shade 10, the assembly is connected to the body 31, and then the three parts are placed in a mold to form the sealing sleeve 50, so that the sealing sleeve 50 can be tightly coated on the sealing plug 30, the assembly and the end part of the lamp shade 10, thereby the sealing performance of the lamp tube 100 is improved. It should be noted that, the sealing sleeve 50 is preferably made of an elastic material, such as TPE, TPU, silica gel, rubber, etc., and after the sealing sleeve 50 is molded, the sealing sleeve is elastically attached to the sealing plug 30, the fitting, and the end of the lampshade 10, that is, the pressure of the sealing sleeve 50 is derived from its own elastic force. The sealing performance of the lamp tube 100 is thus further improved.

Further, the sealing sleeve 50 is provided with a first injection molding positioning hole 50a, the sealing plug 30 is provided with a second injection molding positioning hole 30a, and the first injection molding positioning hole 50a is communicated with the second injection molding positioning hole 30 a.
