The sealing end covers 25 are respectively provided at both ends of the main body 21. The main body 21 has an inner concave portion, and a light-emitting component 26 is installed in the inner concave portion. The light-emitting component 26 includes a circuit board and a lamp bead arranged on the circuit board. The circuit board can be a hard plate or a flexible plate, which can be selected according to actual needs; both sides of the main body 21 have support platforms 211, and the outer edge of the support platform 211 is bent upward and extended to form a first retaining edge 212. Preferably, the main body 21, the support platform 211 and the first retaining edge 212 are an integrated structure formed by integral processing; the bottom surface of the sealing strip 23 contacts the top surface of the support platform 211, and the inner side surface of the first retaining edge 212 contacts the outer surface of the sealing strip 23. On the side, a slot 231 is provided on the inner side of the sealing strip 23, and a through hole 232 is provided on the top surface of the sealing strip 23 to communicate with the bottom surface thereof, and the through hole 232 communicates with the slot 231, and the long side of the glass plate 22 is inserted into the slot 231, and the long side of the glass plate 22 has a notch 221 arranged corresponding to the through hole 232, and the pressure strip 24 includes a positive pressure piece 241 and a second rib 242 connected vertically, and the positive pressure piece 241 has a connecting column 243 that penetrates into the through hole 232, and a threaded hole 244 is provided on the bottom surface of the connecting column 243, and the bottom surface of the positive pressure piece 241 presses against the top surface of the sealing strip 23, and the inner side surface of the second rib 242 contacts the outer side surface of the sealing strip 23, and also includes a fastening screw, one end of which passes through the support platform 211 and connects to the threaded hole 244.
[0036] There is a gap between the first rib 212 and the second rib 242. After the mining lamp 2 is assembled, a part of the deformed area of the sealing strip 23 invades the gap. Preferably, the area of the sealing strip 23 invading the gap is tightly fitted with the top surface of the first rib 212 and the bottom surface of the second rib 242, respectively.
[0037] The connecting column 243 is not in contact with the support platform 211 , which not only reduces the processing accuracy requirements of the pressure strip 24 , but also allows the sealing strip 23 to fully deform after the mining lamp 2 is assembled, thereby ensuring the sealing and waterproof effect of the long side of the mining lamp 2 .
[0038] In this embodiment, the slot 231 is not connected to the outer side surface of the sealing strip 23 .
[0039] There are multiple connecting columns 243 on the pressure strip 24, and preferably, the multiple connecting columns 243 are evenly spaced along the length direction of the positive pressure plate 241, so that each area in the length direction of the sealing strip 23 can be deformed more evenly to ensure the sealing and waterproof effect of the long side of the industrial and mining lamp 2.
[0040] The lighting device further comprises a power supply box 3 arranged on the bracket 1 , two ends of the mining lamp 2 are rotatably connected to the bracket 1 , and the power supply box 3 is electrically connected to the light-emitting component 26 .
[0041] In this embodiment, Figure 1 As shown, the bracket 1 is in an I-shape as a whole, and the bracket 1 includes a first rod and two second rods 11, the two ends of the first rod are respectively connected to the second rods 11, the power box 3 is arranged on the first rod, the two ends of the mining lamp 2 are respectively connected to the two second rods 11, and the end of the mining lamp 2 is provided with a rotation hole 27.

One end of the pull pin 4 is an axial end 41. The axial end 41 passes through the second rod 11 and is inserted into the rotating hole 27. The mining lamp 2 is rotatably arranged around the axial end 41. The other end of the pull pin 4 is exposed on the outside of the second rod 11. The pull pin 4 is slidably arranged along the length direction of the mining lamp 2. An elastic member 5 is provided in the second rod 11. A limiting portion 42 is provided on the pull pin 4. The elastic member 5 contacts the pull pin 4 and the limiting portion 42 respectively to drive the axial end 41 to be inserted into the rotating hole 27. The pull pin 4 is non-rotatable relative to the second rod 11. Such a structure can facilitate the disassembly and assembly of the mining lamp 2 on the bracket 1. When the staff needs to disassemble the mining lamp 2, the pull pin 4 can be pulled to allow the axial end 41 to withdraw from the rotating hole 27, and then the mining lamp 2 is removed from the bracket 1.
[0042] The lighting device further includes a first damping gasket 61 and a second damping gasket 62 that cooperate with each other, wherein the first damping gasket 61 is fixed to the end of the mining lamp 2, and the second damping gasket 62 is fixed to the inner side of the second rod 11. The cooperation between the first damping gasket 61 and the damping gasket can prevent the mining lamp 2 from accidentally rotating relative to the bracket 1, which is beneficial to ensuring the user experience.
[0043] In a specific product, a plurality of the mining lamps 2 can be installed on a single bracket 1. For example, in this embodiment, the number of the mining lamps 2 is four, and two mining lamps 2 are installed at both ends of the power box 3 respectively.
