For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Combine the following Figures 1 to 3 The utility model is described in detail.

[0023] A tunnel lighting system includes a tunnel 1, a lighting device 3 is arranged on the top of the inner wall of the tunnel 1, a bulb 301 is arranged at the bottom of the lighting device 3, an infrared sensor 2 is arranged on one side of the inner wall of the tunnel 1, a transmission cable 201 is arranged on one side of the infrared sensor 2, the infrared sensor 2 is connected to the lighting device 3 through the transmission cable 201, the lighting device 3 is connected to a cleaning component, the cleaning component swings along the axis, and the cleaning component swings in contact with the surface of the bulb 301, several lighting devices 3 and infrared sensors 2 in the tunnel 1 are connected in series through the transmission cable 201, the transmission cable 201 is connected to a control terminal in the lighting device 3, the lighting device 3 includes an installation cavity 302 and a transmission motor 3021, the installation cavity 302 is arranged on one side of the bottom of the lighting device 3, the transmission motor 3021 is connected in the installation cavity 302, and the driving power supply of the transmission motor 3021 is linearly connected to the terminal through a cable.

[0024] First, when a vehicle or a person enters the tunnel 1 and passes the infrared sensor 2, the human body will emit infrared radiation. When the human body approaches the sensing light, the infrared sensor will receive the radiation, and then transmit the collected infrared signal to the control terminal through the transmission cable 201, and then control the lighting device 3 to turn on, so that the light bulb 301 will emit light to illuminate the tunnel.

[0025] At the same time, if a vehicle passes by, because the infrared radiation signals emitted by people and vehicles are different, when it is distinguished that the vehicle is passing, the control terminal will control the lighting device 3 located in the front to turn on, to illuminate a certain distance in front of the vehicle in advance, so as to ensure the driving safety of the vehicle, thereby avoiding the need for human control of the lighting lamp. After the person and the vehicle completely pass the infrared sensor 2, the delay module will control the lighting lamp to turn off automatically after a certain period of time, thereby avoiding the cumbersome opening and closing of the lights, and the problem of excessive power consumption if all the lights are turned on at once.

[0026] Furthermore, the cleaning component includes a cleaning arc block 303, a hinge shaft 3031, a transmission tooth groove 3032 and a brush 3033. The cleaning arc block 303 is connected to the bottom of the lighting device 3, the hinge shaft 3031 is arranged at both ends of the cleaning arc block 303, the transmission tooth groove 3032 is arranged on the side wall portion of the hinge shaft 3031, and the brush 3033 is arranged on the inner wall of the cleaning arc block 303. The cleaning arc block 303 is an arc-shaped long strip that matches the curvature of the surface of the bulb 301, and the cleaning arc block 303 is rotatably connected to the bottom sides of the lighting device 3 through the hinge shafts 3031 at both ends. The transmission tooth groove 3032 is arranged on the side wall portion of the hinge shaft 3031 at one end of the cleaning arc block 303, and the transmission tooth groove 3032 is meshed with the gear connected to the transmission motor 3021 at one end, and the coverage area of ​​the transmission tooth groove 3032 is only a part of the side wall of the hinge shaft 3031.

[0027] At the same time, when the control terminal receives a signal to turn on the lighting device 3 for lighting, it will also control to turn on the power connected to the transmission motor 3021, so that the power supply will supply energy to the transmission motor 3021, so that the transmission motor 3021 can run. When the transmission motor 3021 is running, the transmission gear connected at one end will engage with the transmission tooth groove 3032 on the hinge shaft 3031 at one end of the cleaning arc block 303, so that when it rotates, it will drive the hinge shaft 3031 at one end to rotate, and when the hinge shaft 3031 rotates, it will drive the entire cleaning arc block 303 to deflect along the axis, so that the brush 3033 on the inner wall will stick to the surface of the bulb 301 for cleaning, so as to clean the dust attached to its surface, so as to prevent too much dust in the tunnel from adhering to the surface of the bulb 301 and affecting the light irradiation range.

[0028] At the same time, the transmission motor 3021 will reset itself after rotating a certain angle through the control of the control terminal to reset the cleaning arc block 303, thereby facilitating repeated use. At the same time, because the transmission tooth groove 3032 is only provided on the side wall portion of the articulated shaft 3031, the rotation angle of the transmission motor 3021 has a certain tolerance. When the gear rotates to the point where the transmission tooth groove 3032 is not provided, it will not drive the articulated shaft 3031 to continue rotating.

[0029] The following is a specific implementation process of the utility model. First, when a vehicle or a person enters the tunnel 1 and passes through the infrared sensor 2, the human body will emit infrared radiation. When the human body approaches the sensing light, the infrared sensor will receive these radiations, and then transmit the collected infrared signals to the control terminal through the transmission cable 201, and then control the lighting device 3 to turn on, so that the bulb 301 will emit light to illuminate the tunnel. At the same time, if a vehicle passes by, because the infrared radiation signals emitted by people and vehicles are different, because when it is distinguished that the vehicle is passing, the control terminal will control the lighting device 3 located in the front to turn on, to illuminate a certain distance in front of the vehicle in advance, so as to ensure the driving safety of the vehicle, thereby avoiding the need for manual control of the lighting lamp, so that after the person and the vehicle completely pass the infrared sensor 2, through the control of the delay module, it will automatically turn off after a certain period of time, so as to avoid the problem that the opening and closing of the lights are more cumbersome, and if all are turned on at once, the problem of excessive power consumption.
