In other embodiments, the sealing strip 41 can also be positioned below the light-emitting plate 30, and the side pressure strip 42 can be positioned above the light-emitting plate 30 accordingly. Those skilled in the art can choose according to their needs.

[0063] In this embodiment, a vertical first limiting groove 132 is provided on the inner wall of the mounting groove 13, and a vertical first limiting protrusion 411 is provided on the sealing strip 41 corresponding to the first limiting groove 132. The first limiting protrusion 411 is inserted into the first limiting groove 132 to limit the left and right movement of the sealing strip 41. It can position and limit the sealing strip 41, which facilitates the accurate installation of the sealing strip 41 and can also prevent the sealing strip 41 from shifting, misaligning or loosening during use, making it more reliable. In this embodiment, the cross-sections of the first limiting groove 132 and the first limiting protrusion 411 are both square, and they are located on the outer side of the mounting groove 13 and the sealing strip 41, respectively. Even if the cross-section of the sealing strip 41 is "L" shaped, the first limiting groove 132 also utilizes the bottom surface of the mounting groove 13 as a side surface, which facilitates processing, manufacturing and assembly. In other embodiments, the position and shape of the first limiting protrusion 411 on the sealing strip 41 and the position and shape of the first limiting groove 132 on the inner wall of the mounting groove 13 can be flexibly adjusted as needed. For example, the first limiting protrusion 411 can also be set in the middle of the sealing strip 41. The first limiting protrusion 411 and the first limiting groove 132 can also adopt other arbitrary shapes such as semicircle, triangle, trapezoid, etc., and the shapes of the first limiting protrusion 411 and the first limiting groove 132 can also be different. In this embodiment, the first limiting protrusion 411 is a continuous strip extending from front to back, and the first limiting groove 132 is also a through groove extending in the front-back direction, which facilitates the installation and removal of the sealing strip 41. In other embodiments, the first limiting protrusion 411 may also be selected as a plurality of spaced protrusion structures or other suitable structures, and is not limited to this.

[0064] In this embodiment, a vertical second limiting groove 133 is provided on the inner wall of the mounting groove 13, and a vertical second limiting protrusion 421 is provided on the side pressure strip 42 corresponding to the second limiting groove 133. The second limiting protrusion 421 is inserted into the second limiting groove 133 to limit the left and right movement of the side pressure strip 42. It can also position and limit the side pressure strip 42, ensuring accurate installation of the side pressure strip 42 and preventing the sealing strip 41 from shifting, misaligning, or loosening during use, making it more reliable. In this embodiment, the second limiting groove 133 and the second limiting protrusion 421 are both continuous elongated strips, facilitating the sliding installation and removal of the side pressure strip 42. It should be noted that in this utility model, the cooperation between the first limiting protrusion 411 and the first limiting groove 132, and the cooperation between the second limiting protrusion 421 and the second limiting groove 133, can be used independently.

[0065] In this embodiment, a vertical baffle 422 is provided on one side of the side pressure strip 42. The baffle 422 extends in the direction away from the light-emitting plate 30. The baffle 422 can position the side pressure strip 42, improve the aesthetics, and provide protection.

[0066] In this embodiment, the width of the second limiting protrusion 421 gradually decreases from its bottom to its top in the left-right direction, while the width of the second limiting groove 133 gradually increases from its bottom to its opening in the left-right direction. Thus, when installing the side pressure strip 42, the side pressure strip 42 can be used to squeeze out the smooth plate 30 to compress the sealing strip 41, causing a certain deviation in the vertical position between the second limiting protrusion 421 and the second limiting groove 133. Combined with the shapes of the second limiting protrusion 421 and the second limiting groove 133, a large gap can be made between the second limiting protrusion 421 and the second limiting groove 133 in the left-right direction, making it convenient to insert the second limiting protrusion 421 into the second limiting groove 133. In this embodiment, both the second limiting protrusion 421 and the second limiting groove 133 are trapezoidal, which helps to ensure structural strength. Furthermore, in this embodiment, the width of the second limiting groove 133 in the left-right direction is slightly larger than that of the second limiting protrusion 421, allowing the second limiting protrusion 421 to be easily inserted into the second limiting groove 133 without compressing the sealing strip 41, facilitating assembly. In other embodiments, the width of the second limiting protrusion 421 may gradually decrease from its bottom to its top in the left-right direction, or the width of the second limiting groove 133 may gradually increase from its bottom to its opening in the left-right direction. The shape and dimensions of the second limiting groove 133 and the second limiting protrusion 421 can also be matched, and those skilled in the art can flexibly choose according to their needs.

[0067] This embodiment also includes a lamp body 10 and an end cap 50. The bottom of the lamp body 10 is provided with a light outlet 12.

The end cap 50 is detachably mounted on the lamp body 10 and closes the first mounting opening 131 for easy disassembly and assembly.

[0068] In this embodiment, a sealing element 60 is provided between the end cap 50 and the lamp body 10, which helps to improve the sealing effect. The sealing gasket can be made of common sealing materials such as rubber and silicone.

[0069] In this embodiment, the bottom surface of the light-emitting plate 30 is located a distance above the bottom end of the light-emitting port 12. The sealing member 60 has a protruding plate portion 61 inserted into the end of the light-emitting port 12. The protruding plate portion 61 is in close contact with the bottom surface of the light-emitting plate 30, and the left and right width of the protruding plate portion 61 is adapted to the left and right width of the end of the light-emitting port 12. This can improve the waterproof and dustproof effect, and also help reduce the glare at the end of the lamp, thus helping to improve the lighting effect.

[0070] In this embodiment, a receiving cavity 11 is provided inside the lamp body 10. The receiving cavity 11 extends along the front-back direction to the end wall penetrating the lamp body 10 to form a second mounting port. The second mounting port is closed by an end cap 50 and a sealing member 60. A sealing boss 62 adapted to the second mounting port is provided on the sealing member 60. The sealing boss 62 is inserted into the second mounting port, which helps to accurately position and limit the sealing member 60, facilitates assembly, prevents the sealing member 60 from shifting or loosening during use, and helps to improve the sealing effect. At the same time, it can also reduce the processing difficulty of the end cap 50 and the lamp body 10, so that the lamp body 10 can be cut from a continuously formed profile, which helps to improve production efficiency and reduce product costs. In other embodiments, a groove can also be provided at the end cap 50 or the end of the lamp body 10, and the sealing member 60 can be positioned and limited by placing it in the groove. Alternatively, the sealing member 60 can be positioned by screws, pins, etc., and is not limited to these methods.

[0071] In this embodiment, the end cap 50 is provided with an insertion groove 51 that is adapted to the end of the lamp body 10. The end of the lamp body 10 is inserted into the insertion groove 51, which can position the end cap 50, facilitate assembly, and help improve the waterproof and dustproof effect of the lamp. In particular, combined with the setting of the sealing element 60, it can effectively improve the protective performance, and can also pre-position and protect the sealing element 60, further facilitating assembly.

[0072] In this embodiment, the lighting assembly 103 includes a light source 20, which is disposed within the accommodating cavity 11. A first insertion slot 14 is provided on the inner top surface of the accommodating cavity 11 of the lamp body 10.
