[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-5. This utility model is a tunnel lighting device that is easy to install and maintain. It includes a housing 1, a mounting plate 2 fixedly connected to one side of the housing 1, a heat sink 3 fixedly connected to one side of the housing 1, a controller 4 fixedly connected to one side of the housing 1, an LED light panel 5 disposed inside the housing 1, and a sealing plate assembly disposed inside the housing 1. The sealing plate assembly includes a first magnet 6 disposed inside the housing 1, an anti-detachment plate 7 magnetically attracted to one side of the first magnet 6, a transparent plate 8 fixedly connected to one side of the anti-detachment plate 7, a second magnet 9 disposed outside the housing 1, and a sealing plate 10 magnetically attracted to the surface of the second magnet 9. Through the setting of the sealing plate assembly and the magnetic design, the housing 1 can be opened and closed quickly without tools, simplifying maintenance operations. The transparent plate 8 acts as a protective cover to protect the internal LED light panel 5 while allowing light to pass through. The sealing plate 10 cooperates with the sealing strip 16 to ensure the dustproof and waterproof performance of the housing 1, which requires maintenance. When installing, simply pull open the closed plate 10 and release the magnetic attraction to remove the transparent plate 8, which directly contacts the internal LED light panel 5 without disassembling the entire outer shell 1, significantly reducing maintenance time. The outer shell 1 is equipped with a fixing component, which includes a limiting plate 11 fixedly connected inside the outer shell 1, a fixing groove 12 opened on one side of the LED light panel 5, and a fixing plate 13 set inside the fixing groove 12. Through the setting of the fixing component, the limiting plate 11 and the limiting groove provide a standardized installation position for the LED light panel 5, ensuring quick alignment and reducing manual adjustment. The spring 18 clamping mechanism, through the cooperation of the slide rod 17 and the spring 18, makes the fixing plate 13 automatically press into the fixing groove 12 of the LED light panel 5, forming a firm engagement and preventing loosening and displacement. During installation, simply push the LED light panel 5 into the limiting groove, and the spring 18 drives the fixing plate 13 to automatically lock, without the need for bolts or additional tools, significantly improving installation efficiency.

[0028] Example 2

[0029] Please refer to Figures 1-5. Based on Embodiment 1, the heat sink 3 extends into the interior of the outer casing 1 from the side closest to the casing 1 and contacts the side of the LED light board 5. The heat sink 3 is used to quickly dissipate the heat generated by the LED light board 5. Movable grooves 14 are provided at the top and bottom of the interior of the casing 1. A movable slider 15 is slidably connected inside the movable groove 14. The movable slider 15 is fixedly connected to the anti-detachment plate 7. The movable grooves 14 and the movable slider 15 are used to limit the anti-detachment plate 7, allowing it to slide smoothly. Both the anti-detachment plate 7 and the sealing plate 10 are made of magnetic material. The transparent plate 8 is fixedly connected to the sealing plate 10 from the side away from the anti-detachment plate 7. The magnetic material of the anti-detachment plate 7 and the sealing plate 10 allows the first magnet 6 and the second magnet 9 to magnetically attract the anti-detachment plate 7 and the sealing plate 10 respectively. A fitting is provided on one side of the outer casing 1 to the transparent plate 8. The inlet and outlet slots are fixedly connected to a sealing strip 16. The inlet and outlet slots and the sealing strip 16 allow the transparent plate 8 to be pulled outward. The sealing strip 16 provides a seal. There are four limiting plates 11. The surface of the limiting plates 11 is provided with limiting grooves that are compatible with the LED light panel 5. By setting four limiting plates 11, the LED light panel 5 is limited, which facilitates quick positioning of the installation position. Slide rods 17 are fixedly connected to both sides inside the outer shell 1. Springs 18 are sleeved on the surface of the slide rods 17. The fixed plate 13 is provided with a sliding slot that is compatible with the slide rods 17. The slide rods 17 are located inside the sliding slots. A baffle is fixedly connected to the other end of the slide rods 17. The slide rods 17 and the springs 18 are used to limit the fixed plate 13, allowing the fixed plate 13 to slide smoothly. The springs 18 compress the fixed plate 13 to prevent the fixed plate 13 from sliding after installation.

[0030] The working principle of this utility model is as follows: When maintenance is required, the operator first pulls the sealing plate 10 outward. The sealing plate 10 drives the transparent plate 8 and the anti-detachment plate 7, which are fixedly connected to it, to move synchronously along the moving slide 14. Under the guidance of the moving slider 15, the transparent plate 8 slides smoothly out of the inlet and outlet slot of the outer shell 1, and the maintenance window of the outer shell 1 is fully opened. This process does not require the assistance of tools. At this time, the LED light panel 5 is exposed, and personnel can directly contact the LED light panel 5.

[0031] After exposing the LED light panel 5, the operator presses the fixing plate 13, which moves axially along the slide rod 17, compressing the spring 18 to produce elastic deformation. When the fixing plate 13 completely exits the fixing groove 12 of the LED light panel 5, the limiting groove constraint of the limiting plate 11 is released, and the damaged LED light panel 5 can be vertically pulled out along the limiting groove track. During replacement, the four corners of the new LED light panel 5 are precisely embedded into the limiting grooves of the four sets of limiting plates 11. After releasing the fixing plate 13, the spring 18 releases the preload to drive the fixing plate 13 to reset, and its front wedge structure automatically engages with the fixing groove 12, forming a three-point positioning mechanical lock. At this point, the replacement of the LED light panel 5 is complete. Finally, the transparent plate 8 is reset and pushed into the housing 1.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
