[0004] However, since the brightness of the lighting in the above-mentioned prior art is much lower than the brightness outside, when a driver just enters a tunnel during the day, the brightness outside the tunnel is much higher than that inside the tunnel. After entering the tunnel, the driver enters a darker tunnel from the bright outside. It takes a certain amount of time for the vision to adapt before the driver can see the situation inside the tunnel clearly. At the tunnel exit, a very bright exit will appear, which will cause strong glare to the driver, making it difficult to see the road conditions clearly, which is prone to traffic accidents.

[0018] The locking assembly includes a stopping pin and a first elastic member, the stopping pin is adapted to the through hole, the stopping pin is slidably installed in the through hole, so as to have a stopping state in which one end extends into the sliding groove and an unlocking state in which the sliding groove is exited, the two ends of the first elastic member are respectively connected to the stopping pin and the mounting frame, and the first elastic member is used to drive the stopping pin to be in the stopping state.

[0019] In some embodiments, the end of the stopping pin facing the sliding slot is arranged in an arc shape.

[0020] In some embodiments, the enhanced lamp also includes a baffle, which is elastically and telescopically installed on the side of the limiting structure facing the slide groove through a second elastic member, and the baffle abuts against the lamp body so that when in the unlocked state, the baffle drives the lamp body to move toward the open end of the slide groove.

[0021] In some embodiments, the limiting structure is provided with a threaded hole;

[0022] The enhanced lamp also includes an adjusting bolt, which is threadedly connected to the threaded hole. The second elastic member is located in the threaded hole, and one end of the second elastic member is connected to the adjusting bolt, and the other end of the second elastic member is connected to the baffle, so that the baffle is elastically telescopic.

[0025] Since the lighting lamps only need to ensure basic lighting, the spacing between the lighting lamps is much larger than the spacing between the first enhancement lamps and the second enhancement lamps. Under the premise of ensuring lighting, the number of the lighting lamps is reduced and the energy consumption is reduced. The entrance section is a process from light to dark, so more of the first enhancement lamps are needed to enhance the brightness at the entrance section, while the exit section is a process from dark to light, so it is only necessary to appropriately enhance the brightness there.

[0040] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0041] See also Figure 1 The tunnel lighting system is applied to a tunnel 200, which includes an entrance section 210, a middle section 220 and an exit section 230 connected in sequence. The tunnel lighting system includes a plurality of lighting lamps 1 and a plurality of reinforcement lamps 2. The plurality of lighting lamps 1 are evenly arranged in the tunnel 200 along the length direction of the tunnel; the plurality of reinforcement lamps 2 include a plurality of first reinforcement lamps 2a and a plurality of second reinforcement lamps 2b. The plurality of first reinforcement lamps 2a are evenly arranged in the entrance section 210 along the length direction of the tunnel, and the plurality of second reinforcement lamps 2b are evenly arranged in the exit section 230 along the length direction of the tunnel; wherein the spacing between two adjacent lighting lamps 1 is L1, the spacing between two adjacent first reinforcement lamps 2a is L2, and the spacing between two adjacent second reinforcement lamps 2b is L3, and L1>L3>L2.

[0042] The utility model provides a tunnel lighting system, wherein a plurality of the lighting lamps 1 are evenly arranged in the tunnel 200 along the length direction of the tunnel; a plurality of the first reinforcement lamps 2a are evenly arranged in the entrance section 210 along the length direction of the tunnel, and a plurality of the second reinforcement lamps 2b are evenly arranged in the exit section 230 along the length direction of the tunnel; the spacing between two adjacent lighting lamps 1 is L1, the spacing between two adjacent first reinforcement lamps 2a is L2, and the spacing between two adjacent second reinforcement lamps 2b is L3, L1>L3>L2, and the lighting lamps 1 are used as basic lighting tools in the tunnel 200, and only need to ensure basic lighting, and at the entrance The first enhancement lamp 2a is provided at the entrance section 210 to enhance the brightness at the entrance section 210, ensure that the brightness of the entrance section 210 is equivalent to the external brightness, eliminate the black hole phenomenon, and enable the driver to quickly adapt and thus see the situation inside the tunnel 200 clearly. The second enhancement lamp 2b is provided at the exit section 230 to enhance the brightness at the exit section 230, ensure that the brightness of the exit section 230 is equivalent to the external brightness, eliminate the white hole phenomenon, and avoid strong glare, which may lead to unclear road conditions and traffic accidents. By using the lighting lamp 1 in combination with the enhancement lamp 2, the brightness of the entrance and exit of the tunnel 200 is guaranteed and the energy consumption is reduced.

[0043] Since the lighting lamps 1 only need to ensure basic lighting, the spacing between the lighting lamps 1 is much larger than the spacing between the first enhancement lamps 2a and the second enhancement lamps 2b. Under the premise of ensuring lighting, the number of the lighting lamps 1 is reduced and the energy consumption is reduced. The entrance section 210 is a process from light to dark, so more of the first enhancement lamps 2a are needed to enhance the brightness at the entrance section 210, while the exit section 230 is a process from dark to light, so it is only necessary to appropriately enhance the brightness there. Therefore, the spacing between the first enhancement lamps 2a is smaller than the spacing between the second enhancement lamps 2b.

[0044] Furthermore, in this embodiment, 2×L2=L3. With such a configuration, the arrangement is reasonable, and the number of the enhancement lamps 2 is reduced while providing enhanced lighting.

[0045] Furthermore, in this embodiment, the lighting lamp 1 is a 70W LED lamp, the first reinforcement lamp 2a is a 150W LED lamp, and the second reinforcement lamp 2b is a 100W LED lamp.

[0046] For further information, see Figures 1 to 3In order to improve the lighting intensity, in this embodiment, multiple lighting lamps 1 constitute a lighting lamp group 1, multiple first reinforcement lamps 2a constitute a first reinforcement lamp 2a group, and multiple second reinforcement lamps 2b constitute a second reinforcement lamp 2b group. Two of each of the lighting lamp group 1, the first reinforcement lamp group 2a, and the second reinforcement lamp group 2b are symmetrically arranged along the center line of the tunnel 200.

[0047] For further information, see Figures 2 to 3 In order to ensure that the driver can clearly see the ground inside the tunnel 200 at the entrance section 210 and the driver can clearly see the ground outside the tunnel 200 at the exit section 230, in this embodiment, the intersection of the light beams of the two first enhanced light groups 2a and the intersection of the light beams of the two second enhanced light groups 2b are both located at the center line of the ground, and the intersection of the light beams of the two lighting lamps 1 groups is located above the ground. With such an arrangement, the light beams of the two first enhanced light groups 2a and the two second enhanced light groups 2b can converge on the ground of the tunnel 200, thereby ensuring that the brightness of the ground of the tunnel 200 is consistent with that of the ground outside, which is beneficial for the driver to see the road conditions ahead clearly. The lighting lamp 1 is used to provide lighting, so the intersection of the light beams of the two lighting lamps 1 groups can be located above the ground.

[0048] Furthermore, due to weather changes, the brightness of the outside world may also change at any time. In order to adapt to the brightness of the outside world, in this embodiment, the brightness of the first enhanced light 2a and the second enhanced light 2b can be adjusted. In this way, the brightness of the first enhanced light 2a and the second enhanced light 2b can be adjusted in real time according to the brightness of the outside world, which is highly practical.

[0049] It should be noted that the brightness adjustment method and structure of the first enhancement lamp 2a and the second enhancement lamp 2b are both existing technologies and will not be described in detail herein.

[0050] Furthermore, the first enhancement lamp 2a and the second enhancement lamp 2b differ only in power, and their specific structures are the same.

[0051] For further information, see Figure 4In this embodiment, the enhanced lamp 2 includes a mounting frame 21, a lamp body 22 and two locking components 23. The mounting frame 21 is provided with a slide groove 213 on opposite sides. The notches of the slide groove 213 are arranged opposite to each other. One end of the slide groove 213 is opened. The other end of the slide groove 213 is provided with a limiting structure 24. The mounting frame 21 is used to be installed on the side wall of the tunnel 200. The lamp body 22 is slidably installed in the slide groove 213 from the open end of the slide groove 213, and the lamp body 22 is limited by the limiting structure 24 to move toward the other end of the slide groove 213; the two locking components 23 are movably installed at the open ends of the two slide grooves 213 respectively, and are used to limit the lamp body 22 from escaping from the open end of the slide groove 213. Specifically, the side walls on the two opposite sides of the lamp body 22 are provided with convex ribs, the convex ribs are adapted to the slide groove 213, and the convex ribs are slidably installed in the slide groove 213. When in use, the mounting frame 21 is first fixedly installed on the side wall of the tunnel 200, and then the convex ribs on both sides of the lamp body 22 are aligned with the slide groove 213, and the lamp body 22 is pushed into the slide groove 213 from the open end of the slide groove 213, and finally the locking assembly 23 is used to limit the lamp body 22, so as to achieve fixation. The purpose of the lamp body 22 is to replace the lamp body 22 after it is damaged, open the locking assembly 23, and pull the lamp body 22 out of the slide slot 213 to replace the lamp body 22, thereby realizing the quick replacement of the lamp body 22 and improving the work efficiency of replacing the lamp body 22. The sliding installation not only reduces the labor intensity of the workers, but also facilitates the disassembly and installation of the lamp body 22. At the same time, the separate setting of the mounting frame 21 and the lamp body 22 facilitates the installation and fixation of the mounting frame 21.

[0052] For further information, see Figure 5 and Figure 6 In this embodiment, the mounting frame 21 is provided with a through hole connected to the slide slot 213; the locking assembly 23 includes a stop pin 231 and a first elastic member 232, the stop pin 231 is adapted to the through hole, the stop pin 231 is slidably installed in the through hole, and has a stop state in which one end extends into the slide slot 213 and an unlocking state in which the stop pin 231 exits the slide slot 213, the two ends of the first elastic member 232 are respectively connected to the stop pin 231 and the mounting frame 21, and the first elastic member 232 is used to drive the stop pin 231 to be in the stop state. By providing the first elastic member 232, the stop pin 231 is always in the stop state, so that a better locking effect can be achieved to prevent the lamp body 22 from accidentally falling out, and when unlocking is required, the stop pin 231 only needs to be manually pulled out.

[0053] Specifically, a boss is provided at one end of the stop pin 231 away from the slide groove 213, and the diameter of the boss is larger than the diameter of the stop pin 231. The first elastic member 232 is a tension spring, and the tension spring is sleeved on the outer periphery of the stop pin 231. One end of the tension spring is connected to the boss, and the other end is connected to the mounting frame 21.

[0054] Furthermore, in order to facilitate the installation and removal of the lamp body 22 , in the present embodiment, the end of the stopping pin 231 facing the sliding groove 213 is arranged in an arc shape.

[0055] For further information, see Figure 5 and Figure 7 Since there are two locking assemblies 23, and two of the slide grooves 213 are respectively set, when removing the lamp body 22, both hands are required to pull out the stop pin 231 at the same time, and the lamp body 22 can only be removed by another operator, which is not conducive to disassembly. Therefore, in this embodiment, the enhanced lamp 2 also includes a baffle 25, and the baffle 25 is elastically and telescopically installed on the side of the limiting structure 24 toward the slide groove 213 through a second elastic member 26, and the baffle 25 abuts against the lamp body 22 so that when in the unlocked state, the baffle 25 drives the lamp body 22 to move toward the open end of the slide groove 213. During specific use, when the lamp body 22 is installed in the slide groove 213, the lamp body 22 abuts against the baffle 25 and pushes the baffle 25 to move toward the limiting structure 24, thereby compressing the second elastic member 26. When the lamp body 22 is disassembled, when the two locking pins are pulled out, the baffle 25 will drive the lamp body 22 to move toward the open end of the slide groove 213 under the drive of the second elastic member 26, so that the lamp body 22 partially protrudes from the stop pin 231. At this time, after the stop pin 231 is released, the stop pin 231 abuts against the top of the lamp body 22 and cannot limit the lamp body 22. At this time, the lamp body 22 can be taken out, so that the purpose of completing the disassembly of the lamp body 22 by one person is achieved, and it is easy to use.

[0056] Furthermore, in this embodiment, the limiting structure 24 is provided with a threaded hole; the reinforcing lamp 2 further includes an adjusting bolt 27, the adjusting bolt 27 is threadedly connected in the threaded hole, the second elastic member 26 is located in the threaded hole, and one end of the second elastic member 26 is connected to the adjusting bolt 27, and the other end of the second elastic member 26 is connected to the baffle 25, so that the baffle 25 is elastically retracted. The elastic force of the second elastic member 26 can be adjusted by setting the adjusting bolt 27, so that the elastic force is within an appropriate range, and the elastic force of the second elastic member 26 is prevented from being too large or too small.

[0057] Specifically, the second elastic member 26 is a spring.

[0058] Furthermore, the second elastic member 26 is provided in plurality, and correspondingly, the threaded hole and the adjusting bolt 27 are provided in plurality.

[0059] For further information, see Figure 8 In order to facilitate the adjustment of the angle of the lamp body 22, in this embodiment, the mounting frame 21 includes a first frame 211 and a second frame 212, wherein the first frame 211 is U-shaped and is used to be installed on the side wall of the tunnel 200, and the second frame 212 is rotatably installed at both ends of the first frame 211, wherein the slide groove 213 is located at the second frame 212. In this way, the lamp body 22 can be rotated by rotating the second frame 212, thereby adjusting the angle of the lamp body 22.
