Description

Technical Field

[0001] This utility model relates to the field of tunnel lighting technology, specifically a multi-module tunnel light. Background Technology

[0002] Tunnel lights are special lighting fixtures designed specifically for tunnel illumination. They have advantages such as high brightness, reasonable light distribution, good heat dissipation, and corrosion resistance. Tunnel lights can provide sufficient brightness in tunnels, ensuring the driving safety of vehicles inside the tunnel. In addition, tunnel lights have a long service life and low power consumption, effectively reducing the operating costs of tunnel lighting.

[0003] Chinese Patent Publication No. CN 217441473 U discloses a novel tunnel light, including a tunnel light body. An aluminum substrate and a lamp cover plate are sequentially arranged at the front end of the tunnel light body. A plurality of LED beads are arranged on the aluminum substrate. A plurality of spherical lamp covers corresponding to the LED beads are arranged on the lamp cover plate. A plurality of heat dissipation plates are arranged on the back of the tunnel light body. The heat dissipation plates are riveted to the tunnel light body. Each heat dissipation plate is fixedly connected to the other by a positioning strip.

[0004] The aforementioned tunnel light has a one-piece design, with fixed mounting holes at both ends for fixed connection to the tunnel. The mounting portion is a flat rectangular plate, making it impossible to adjust the direction of the light after installation. Since tunnels require both vertical and inclined lighting, an inclined mounting platform needs to be installed in the tunnel to produce inclined lighting, increasing the difficulty and cost of installation. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-module tunnel light that uses a cable tray to fix the tunnel light in the tunnel. By loosening the fixing bolts, the two connecting brackets can rotate around the connecting shaft, thereby adjusting the lighting direction of the tunnel light, increasing the applicable range of tunnels, and reducing the difficulty of installing the tunnel light, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-module tunnel light includes a housing, with a battery fixedly connected to the top center of the housing; a light panel is provided on the inner side of the housing; connecting frames are fixedly connected to both ends of the top of the housing; a bridge is provided above the battery, with connecting shafts fixedly connected to both ends of the bridge, and the ends of the two connecting shafts away from the bridge are rotatably connected to the two connecting frames respectively.

[0008] Both of the connecting frames have a connecting plate fixedly connected to their bottoms, and both connecting plates are fixedly connected to the top of the outer shell by multiple connecting bolts; both of the connecting frames have an arc-shaped groove at their upper ends, and both arc-shaped grooves have fixing bolts on their inner sides, and the two fixing bolts are threaded to both ends of the cable tray respectively.

[0009] As a further technical solution of this utility model, one end of the cable tray is provided with a pointer, which is located outside the cable tray and above the connecting frame; the upper end of the connecting frame closer to the pointer in the two connecting frames is provided with a scale groove.

[0010] As a further technical solution of this utility model, a circuit board is installed inside the outer shell, and a heat dissipation fin is provided above the circuit board, and the heat dissipation fin is fixedly connected to the inner wall of the outer shell; the length of the circuit board is less than the length of the heat dissipation fin.

[0011] As a further technical solution of this utility model, a lamp board is provided below the circuit board, and the lamp board is installed inside the housing; the two ends of the lamp board are respectively attached to the two ends of the heat dissipation fins; the lamp board is electrically connected to the circuit board.

[0012] As a further technical solution of this utility model, a lampshade is embedded in the bottom of the outer shell, and the lampshade is located below the lamp panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model first fixes the cable tray to the inner wall of the tunnel. By loosening two fixing bolts, the connection between the cable tray and the two connecting brackets can be loosened, allowing the outer shell and the two connecting brackets to rotate around the connecting shaft, thereby changing the lighting direction of the tunnel light. There is sufficient space between the cable tray and the outer shell, ensuring that the battery on the top of the outer shell is not blocked by the cable tray when the outer shell rotates, thus ensuring that the outer shell can rotate normally. After the outer shell has rotated, the two fixing bolts are tightened again to fix the position of the outer shell. When rotating the outer shell and the connecting brackets, the pointer cooperates with the connecting bracket with the scale groove to intuitively display the rotation angle of the connecting bracket, thereby increasing the accuracy of the outer shell rotation.

[0015] 2. In this utility model, the battery is electrically connected to the circuit board. The circuit board and the light board generate a certain amount of heat during operation. The heat dissipation fins can absorb the heat and dissipate it to the outside through the outer shell, thereby increasing the heat dissipation effect of the track light. The battery is located outside the outer shell, and the heat generated by the battery can be directly dissipated into the air, thereby reducing the working pressure of the heat dissipation fins and preventing excessive heat accumulation inside the outer shell.

[0016] 3. In this utility model, the lampshade serves to protect the lamp board and circuit board, preventing dust and debris from accumulating on them. This not only ensures the lighting effect of the lamp board but also extends the service life of the lamp board and circuit board. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8In this embodiment of the utility model, a multi-module tunnel light includes a housing 2, a battery 1 fixedly connected to the top center of the housing 2; a lamp plate 14 is provided on the inner side of the housing 2; a connecting frame 4 is fixedly connected to both ends of the top of the housing 2; a bridge frame 7 is provided above the battery 1, and a connecting shaft 5 is fixedly connected to both ends of the bridge frame 7, with the ends of the two connecting shafts 5 away from the bridge frame 7 respectively rotatably connected to the two connecting frames 4.

[0028] Both of the connecting frames 4 are fixedly connected to the bottom of a connecting plate 11, and both connecting plates 11 are fixedly connected to the top of the outer shell 2 by multiple connecting bolts 10; both of the connecting frames 4 are provided with an arc-shaped groove 6 at the top, and both arc-shaped grooves 6 are provided with fixing bolts 9 on the inner side, and the two fixing bolts 9 are respectively threaded to both ends of the cable tray 7.

[0029] By adopting the above technical solution, the cable tray 7 is first fixedly connected to the inner wall of the tunnel. By loosening the two fixing bolts 9, the connection between the cable tray 7 and the two connecting frames 4 can be loosened, allowing the outer shell 2 and the two connecting frames 4 to rotate around the connecting shaft 5, thereby changing the lighting direction of the tunnel light. There is sufficient space between the cable tray 7 and the outer shell 2, so that the battery 1 on the top of the outer shell 2 will not be blocked by the cable tray 7 when the outer shell 2 rotates, ensuring that the outer shell 2 can rotate normally. After the outer shell 2 has rotated, the two fixing bolts 9 are tightened again to fix the position of the outer shell 2. When the outer shell 2 and the connecting frames 4 are rotated, the pointer 8 cooperates with the connecting frame 4 with the scale groove to intuitively display the rotation angle of the connecting frame 4, thereby increasing the accuracy of the rotation of the outer shell 2.

[0030] In this embodiment, one end of the cable tray 7 is provided with a pointer 8, which is located outside the cable tray 7 and above the connecting frame 4; the upper end of the connecting frame 4 closest to the pointer 8 is provided with a scale groove.

[0031] The outer casing 2 has a circuit board 13 installed inside, and a heat dissipation fin 12 is provided above the circuit board 13. The heat dissipation fin 12 is fixedly connected to the inner wall of the outer casing 2. The length of the circuit board 13 is less than the length of the heat dissipation fin 12.

[0032] By adopting the above technical solution, the battery 1 is electrically connected to the circuit board 13. The circuit board 13 and the lamp board 14 will generate a certain amount of heat when they are in operation. The heat dissipation fins 12 can absorb the heat and dissipate it to the outside through the outer shell 2, thereby increasing the heat dissipation effect of the track light. The battery 1 is located outside the outer shell 2, and the heat generated by the battery 1 can be directly dissipated into the air, thereby reducing the working pressure of the heat dissipation fins 12 and preventing excessive heat accumulation inside the outer shell 2.

[0033] In this embodiment, a lamp board 14 is provided below the circuit board 13, and the lamp board 14 is installed inside the housing 2; both ends of the lamp board 14 are respectively attached to both ends of the heat dissipation fins 12; the lamp board 14 is electrically connected to the circuit board 13.

[0034] The bottom of the outer casing 2 is fitted with a lampshade 3, which is located below the lamp panel 14.

[0035] By adopting the above technical solution, the lamp cover 3 plays a role in protecting the lamp board 14 and the circuit board 13, preventing dust and debris from accumulating on the lamp board 14 and the circuit board 13, which can not only ensure the lighting effect of the lamp board 14, but also extend the service life of the lamp board 14 and the circuit board 13.

[0036] The working principle of this utility model is as follows: First, the cable tray 7 is fixedly connected to the inner wall of the tunnel. By loosening the two fixing bolts 9, the connection between the cable tray 7 and the two connecting frames 4 can be loosened, allowing the outer shell 2 and the two connecting frames 4 to rotate around the connecting shaft 5, thereby changing the lighting direction of the tunnel light. There is sufficient space between the cable tray 7 and the outer shell 2, so that the battery 1 on the top of the outer shell 2 will not be blocked by the cable tray 7 when the outer shell 2 rotates, ensuring that the outer shell 2 can rotate normally. After the outer shell 2 has rotated, the two fixing bolts 9 are tightened again to fix the position of the outer shell 2. When the outer shell 2 and the connecting frames 4 are rotated, the pointer 8 cooperates with the connecting frame 4 with the scale groove to intuitively display the rotation angle of the connecting frame 4, thereby increasing the accuracy of the rotation of the outer shell 2.

[0037] Furthermore, by replacing the connecting plate 11 with a longer one, the connecting plate 11 can be fixedly connected to multiple housings 2 at the same time, thereby increasing the number of lamp panels 14 of the tunnel light, increasing the lighting intensity and lighting range of the tunnel light, and increasing the number of lamp panels 14 will not affect the normal installation of the cable tray 7.

[0038] Battery 1 is electrically connected to circuit board 13. Circuit board 13 and light board 14 generate a certain amount of heat during operation. Heat dissipation fin 12 can absorb the heat and dissipate it to the outside through housing 2, thereby increasing the heat dissipation effect of track light. Battery 1 is located outside housing 2. The heat generated by battery 1 can be directly dissipated into the air, thereby reducing the working pressure of heat dissipation fin 12 and preventing excessive heat accumulation inside housing 2.

[0039] The lampshade 3 serves to protect the lamp board 14 and the circuit board 13, preventing dust and debris from accumulating on them. This ensures the lighting effect of the lamp board 14 and extends the service life of the lamp board 14 and the circuit board 13.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
