In the embodiment of the present application, the lamp body 100 has two end portions 130 arranged along the length direction, wherein at least one end portion 130 is connected to the end cap 200 in a sealing manner, so as to prevent external impurities (such as moisture, dust, etc.) from entering into the lamp body 100, and prevent the impurities from affecting the normal operation of the lighting fixture.

The end cap 200 extends partially beyond the mounting surface 110 in a direction perpendicular to the mounting surface 110, that is, the portion of the end cap 200 is higher than the mounting surface 110 in the direction perpendicular to the mounting surface 110. Optionally, the end cap 200 may include an inner end cap 210 and an outer end cap 220, at least one end 130 of the lamp body 100 is connected to the inner end cap 210 in a sealing manner, a mounting groove 211 is formed in a side of the inner end cap 210 away from the lamp body 100, the outer end cap 220 is disposed on the inner end cap 210, and the outer end cap 220 covers the mounting groove 211, so that the outer end cap 220 and the mounting groove 211 can enclose to form a mounting space, which may be used for mounting a power supply component of the lighting fixture, and meanwhile, the mounting space is not communicated with the lamp body 100, so that a worker can maintain the power supply component in the mounting space by only opening the outer end cap 220 without detaching a sealing structure between the inner end cap 210 and the lamp body 100. Specifically, the inner end cap 210 partially extends beyond the mounting surface 110 in a direction perpendicular to the mounting surface 110.

The elastic sealing portion 300 is disposed on the mounting surface 110, and the elastic sealing portion 300 extends beyond the mounting surface 110 and the end cap 200 in a direction perpendicular to the mounting surface 110, that is, the elastic sealing portion 300 is higher than the mounting surface 110 and the end cap 200 in the direction perpendicular to the mounting surface 110, and the elastic sealing portion 300 can be pressed by a surface of a mounting base to be elastically deformed.

In the process that the lighting lamp is assembled on the installation base, the elastic sealing part 300 is firstly contacted with the surface of the installation base, the lighting lamp is continuously close to the surface of the installation base, in the process, the elastic sealing part 300 is pressed by the surface of the installation base to generate elastic deformation until the end cover 200 is contacted with the surface of the installation base, after the end cover 200 is contacted with the surface of the installation base, the lighting lamp is difficult to continuously close to the surface of the installation base, at the moment, a gap formed between the installation surface 110 and the surface of the installation base can be sealed by the elastic sealing part 300, and dust is difficult to enter the gap.
