In addition, the descriptions of "first", "second", etc. in the utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0024] In view of the technical defects existing in the related technology, the utility model provides a tunnel light, please refer to Figures 1 to 4 The tunnel lamp comprises: two support plates 100, a lamp holder 200, a stopper 300, a lamp plate 400, a sealing joint 500 and a lampshade 600; wherein the two support plates 100 are fixedly installed on the tunnel wall at intervals, and the two support plates 100 can be fixed on the tunnel wall by using expansion screws, or by using adapters, for example, a steel plate is provided on the tunnel wall, and the support plates 100 are fixed on the steel plate by welding. The installation method of the two support plates 100 fixed on the tunnel wall is not specifically limited here.

[0025] The two ends of the lamp holder 200 are respectively detachably rotatably installed with the corresponding sides of the two supporting plates 100. At this time, there are multiple ways for the lamp holder 200 to be detachably rotatably connected with the two supporting plates 100. For example, the two supporting plates 100 are provided with coaxially arranged rotating holes 121, and rotating columns 270 are convexly provided on both sides of the lamp holder 200. The rotating columns 270 are rotatably connected with the rotating holes 121. In addition, the two supporting plates 100 are made of sheet metal materials, so that they have a certain elastic deformation ability. The rotating columns 270 of the lamp holder 200 can be directly inserted between the supporting plates 100 and allow the corresponding rotating holes 121 to extend out, so that the lamp holder 200 can be conveniently disassembled and maintained;

[0026] For another example, the two support plates 100 are provided with coaxially arranged rotation holes 121, and the two sides of the lamp holder 200 are recessed with matching holes. The tunnel light also includes two independent rotation columns 270, and the two rotation columns 270 are respectively inserted into the rotation holes 121 and the corresponding matching holes, so that the lamp holder 200 can be detachably rotatably installed on the two support plates 100.

[0027] Furthermore, the limiting member 300 is disposed on the lamp holder 200 or the support plate 100 , and the limiting member 300 is used to limit the rotation of the lamp holder 200 , so that the angle of the lamp holder 200 can be fixed after rotation.

[0028] In addition, the lamp board 400 is installed on the lamp holder 200. The lamp board 400 can be installed on the lamp holder 200 by a detachable connection method such as snap connection, screw locking, etc., which is convenient for subsequent maintenance and replacement.

[0029] Taking into account the humid and dusty environment in the tunnel, the lamp board 400 is in long-term contact with the external environment and is prone to short circuit and aging, which will affect its service life. In view of this, in order to avoid a decrease in the service life of the lamp board 400, the lamp holder 200 is penetrated by a through hole 210 along its thickness direction, and the sealing joint 500 is installed on the through hole 210. The electrical cable of the lamp board 400 passes through the other side of the lamp holder 200 from one side of the lamp holder 200 through the sealing joint 500. In addition, the lampshade 600 is sealed and connected to the lamp holder 200 and covers the lamp board 400. In this way, the lamp board 400 is sealed and arranged on the lamp holder 200, isolated from the external environment, and prevented from moisture, so that the service life of the lamp board 400 is improved.

[0030] Through the technical solution of the utility model, the tunnel lamp is provided with two supporting plates 100, and the lamp holder 200 is detachably rotatably mounted on the two supporting plates 100, and a limiting member 300 is provided for limiting the rotation of the lamp holder 200, so that the lamp holder 200 with the lamp board 400 installed can adjust the rotation angle, so that the illumination area of ​​the lamp board 400 is located in the middle of the tunnel, and the lamp holder 200 is detachably mounted on the two supporting plates 100, so that the lamp holder 200 can be disassembled for replacement or maintenance.

[0031] In order to facilitate the fixing of the support plate 100 on the tunnel wall and the connection with the lamp holder 200, in some embodiments of the utility model, the two support plates 100 have a mounting section 110 and a protruding section 120 extending vertically along the side of the mounting section 110, the mounting section 110 is used to be fixedly connected to the tunnel wall, the protruding section 120 is penetrated by a rotation hole 121 along its thickness direction, and rotating columns 270 are provided on both sides of the lamp holder 200, and the two rotating columns 270 respectively pass through the rotating holes 121 and are rotatably connected to the rotating holes 121.

[0032] Furthermore, there are many ways for the limiting member 300 to limit the rotation of the lamp holder 200. For example, the protruding section 120 is further provided with a plurality of through holes, each of which is arranged at intervals along the circumference of the rotating hole 121. The lamp holder 200 is provided with a fixing hole corresponding to the through hole. The limiting member 300 is a limiting rod, and one end of the limiting rod passes through the through hole and is plugged into the fixing hole. In this way, the limiting member 300 can limit the rotation of the lamp holder 200.

[0033] For another example, the protruding section 120 is provided with an arc-shaped through groove 122, which is coaxially arranged with the rotating hole 121, and the lamp holder 200 is provided with a first threaded hole 220 corresponding to the arc-shaped through groove 122. The position-limiting member 300 is a first screw, which passes through the arc-shaped through groove 122 and is threadedly connected with the first threaded hole 220. The first screw is locked with the first threaded hole 220, so that the head of the first screw presses the groove edge of the arc-shaped through groove 122, and the lamp holder 200 is rotated and limited on the support plate 100 by friction, and the arc-shaped through groove 122 is used for position limiting, so that the adjustable angle is large, which is convenient for users to adjust.

[0034] In order to make the lamp holder 200 more stably fixed on the two support plates 100 after rotation adjustment, in this embodiment, second threaded holes 230 are provided on both sides of the lamp holder 200, and the two rotation columns 270 are second screws, which pass through the rotation holes 121 and are threadedly connected with the second threaded holes 230. After the lamp holder 200 is rotated and adjusted to a suitable angle, the second screw is threadedly connected with the second threaded hole 230, so that the screw head of the second screw squeezes the support plate 100, so that the lamp holder 200 can be more stably connected with the support plate 100.

[0035] In some embodiments, the protruding section 120 is provided with a scale marking line 123 along the circumference of the rotating hole 121, and the lamp holder 200 is provided with a directional mark 240 at a position corresponding to the scale marking line. This makes it convenient for the user to adjust the rotating angle of the lamp holder 200.

[0036] During construction in a tunnel, construction workers are prone to scratching the tunnel lamp. To prevent the lamp panel 400 of the tunnel lamp from being scratched, in this embodiment, the lamp holder 200 is provided with a recessed mounting groove 250, and the lamp panel 400 and the lamp cover 600 are both mounted in the mounting groove 250. In this way, the lamp panel 400 and the lamp cover 600 will not protrude from the surface of the lamp holder 200, thereby preventing them from being scratched.

[0037] Considering that the lamp board 400 generates heat during long-term operation, and the lamp board 400 is sealed in the mounting groove 250 by the lamp holder 200 and the lampshade 600, heat is easily accumulated, which affects the service life of the lamp board 400. In view of this, in order to ensure that the lamp board 400 has good heat dissipation, in this embodiment, the lamp holder 200 is integrally formed with an aluminum alloy material, and a heat dissipation fin 260 is provided on the side of the lamp holder 200 facing away from the lamp board 400. The aluminum alloy material has good heat dissipation performance. The lamp board 400 is directly in contact with the lamp holder 200, so that the heat generated by the lamp board 400 can be transferred to the lamp holder 200. The lamp holder 200 is provided with a plurality of heat dissipation fins 260 to dissipate the heat to the external environment. In addition, the lamp holder 200 made of aluminum alloy material also has the performance of light weight and corrosion resistance.

[0038] The lampshade 600 and the lamp holder 200 can be sealed by ultrasonic welding, waterproof glue bonding or sealing with a sealing ring 700. In this embodiment, in order to facilitate the subsequent replacement or maintenance of the lamp board 400, the tunnel lamp includes a sealing ring 700, which is arranged between the lampshade 600 and the lamp holder 200. The lampshade 600 and the lamp holder 200 are connected to clamp the two sides of the sealing ring 700. That is, the lampshade 600 is connected to the lamp holder 200 by a detachable connection method such as screw locking, clamping, etc., and the sealing ring 700 is squeezed, so that the lamp board 400 is surrounded and sealed by the lamp holder 200 and the lampshade 600.

[0039] In the tunnel, the power supply may be unstable. In order to ensure stable lighting of the tunnel lights, in some embodiments, please refer to Figure 1 and Figure 2 The tunnel light also includes a power battery, the battery power 800 is electrically connected to the light board 400 through a sealing joint 500, and the power battery is installed on the side of the lamp holder 200 facing away from the light board 400.
