Description

Technical Field

[0001] This utility model relates to the field of intelligent tunnel lighting technology, specifically to a lighting fixture for highway tunnels. Background Technology

[0002] Highway tunnels are passageways specifically for automobile transportation. With the development of society, economy and production, a large number of expressways have emerged, which has raised the standards for road construction technology, requiring straight routes, gentle slopes, and wide road surfaces. Therefore, when roads pass through mountainous areas, the old plan of winding through mountains has been replaced by tunnel solutions. Tunnel lighting systems are also an important part of tunnel construction, which can better illuminate vehicles.

[0003] Normally, there is an emergency lane on the far right of highways, specifically designed for vehicles involved in accidents to stop. However, most tunnels do not have emergency lanes, so the right-hand lane becomes the emergency lane. Therefore, vehicles involved in accidents in tunnels usually stop on the right side. However, due to poor visibility in tunnels, if an accident vehicle is not noticed in time in the right-hand lane, it can lead to a secondary accident, causing serious loss of life and property. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a lighting fixture for highway tunnels that can provide timely warnings to vehicles behind when a vehicle makes an emergency stop on the right side of the tunnel.

[0005] The basic solution provided by this utility model is as follows: a lighting fixture for highway tunnels, including a pressure-sensing strip, a projection lamp, an embedded light strip, and a controller. The pressure-sensing strip is located at the right edge of the tunnel, the projection lamp is evenly distributed on the tunnel sidewall, and the embedded light strip is an RGB light strip located on the tunnel sidewall. The output end of the pressure-sensing strip is electrically connected to the input end of the controller. The pressure-sensing strip is used to detect road pressure and generate a pressure signal to send to the controller. The output end of the controller is electrically connected to the input ends of the projection lamp and the embedded light strip, respectively. The controller is used to control the projection lamp to project a warning light screen and also to control the RGB light strip to change the display color.

[0006] The principle and advantages of this invention are as follows: Pressure sensors installed at the road edge detect pressure data. When a vehicle stops on the right side of the road, a higher pressure reading is detected. The real-time pressure data is sent to a controller. If the received pressure data exceeds a preset pressure threshold, the controller activates a projection light to project a dynamically flashing, high-intensity warning light screen onto the tunnel sidewall. This light screen may alternate between red and yellow, or display directional arrows and other warning patterns. Using the tunnel sidewall as a display surface, a large, high-brightness warning zone is created, making it highly visible. Directional projection avoids interfering with oncoming or other vehicles traveling normally ahead. Simultaneously, RGB LED strips are controlled to change their display color. Under normal conditions, the RGB LED strips provide illumination for the tunnel. In emergencies, they change to more conspicuous colors and can also incorporate low-frequency flashing to alert following vehicles and prevent collisions with vehicles that have stopped in an emergency.

[0007] Furthermore, it also includes alarm buttons, of which there are several, evenly distributed on the tunnel sidewall, and the output end of the alarm button is electrically connected to the input end of the controller.

[0008] By setting an alarm button, drivers of parked vehicles can issue warnings independently.

[0009] Furthermore, it also includes a light intensity sensor, the output of which is electrically connected to the input of the controller, for collecting the ambient light intensity inside the tunnel. The controller is also used to control the illumination brightness of the RGB light strip based on the ambient light intensity.

[0010] The system uses a light sensor to detect the ambient light level inside the tunnel and controls the brightness of the RGB LED strips based on the ambient light level to provide sufficient illumination for the tunnel.

[0011] Furthermore, it also includes a timing module, which is electrically connected to the controller. The controller is used to start the timing module after receiving a pressure signal. The timing module is used to generate a clock signal and send it to the controller. The controller is also used to control the projection lamp to project an alarm light screen according to the clock signal, and to control the RGB light strip to change the display color.

[0012] The timing module controls the projector to project an alarm light screen and controls the RGB light strip to change its display color only when the detected pressure data reaches a certain time, thus avoiding false alarms.

[0013] Furthermore, it also includes a ground induction coil, the output end of which is electrically connected to the input end of the controller for detecting the speed of vehicles in the tunnel. The controller is also used to control the warning brightness of the RGB light strip according to the speed of vehicles in the tunnel.

[0014] When the alarm is triggered, the brightness of the RGB indicator is controlled according to the speed of vehicles traveling in the tunnel. The faster the vehicle travels, the brighter the warning light becomes, thus improving the warning effect.

[0015] Furthermore, it also includes an alarm module, the input of which is electrically connected to the output of the controller, and the controller is also used to control the alarm module to issue an alarm. Attached Figure Description

[0016] Figure 1 This is a logic block diagram of an embodiment of a lighting fixture for highway tunnels according to the present invention. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The basic implementation examples are as follows: Figure 1 As shown:

[0019] A lighting system for highway tunnels includes a pressure-sensing strip, a projection lamp, an embedded light strip, and a controller. The pressure-sensing strip is located at the right edge of the tunnel. The projection lamps are evenly distributed on the tunnel sidewalls. The embedded light strip is an RGB light strip and is located on the tunnel sidewalls. The output of the pressure-sensing strip is electrically connected to the input of the controller. The pressure-sensing strip detects road pressure and generates a pressure signal, which is sent to the controller. The output of the controller is electrically connected to the inputs of both the projection lamps and the embedded light strip. The controller controls the projection lamps to project a warning light screen and also controls the RGB light strip to change its display color. In this embodiment, the pressure-sensing strip is a long, modular pressure-sensing strip integrating several pressure sensors, located at the right edge of the road in the tunnel. Its output pins are electrically connected to the input pins of the controller. In this embodiment, the controller is an FPC1-100 series PLC controller. The projection lamps are pre-set with warning patterns, and their input pins are electrically connected to the controller pins. The projection lamps are evenly distributed on the tunnel sidewalls. The RGB light strip is a color-changing light strip and is embedded in the tunnel sidewalls.

[0020] It also includes several alarm buttons, which are evenly distributed on the tunnel sidewalls. The output of the alarm button is electrically connected to the input of the controller.

[0021] It also includes a light intensity sensor, the output of which is electrically connected to the input of the controller, for collecting the ambient light intensity inside the tunnel. The controller is also used to control the illumination brightness of the RGB light strip based on the ambient light intensity. In this embodiment, the light intensity sensor is specifically a WN-109 light sensor.

[0022] It also includes a timing module, which is electrically connected to the controller. The controller activates the timing module upon receiving a pressure signal. The timing module generates a clock signal and sends it to the controller. The controller also controls the projection lamp to project an alarm light screen based on the clock signal and controls the RGB LED strip to change its display color. In this embodiment, the timing module is specifically a DS1302 clock chip.

[0023] It also includes a ground induction coil, the output of which is electrically connected to the input of the controller to detect the speed of vehicles in the tunnel. The controller is also used to control the warning brightness of the RGB light strip according to the speed of vehicles in the tunnel.

[0024] It also includes an alarm module, the input of which is electrically connected to the output of the controller. The controller is also used to control the alarm module to issue an alarm. In this embodiment, the alarm module is specifically a buzzer.

[0025] Specifically, under normal conditions, the RGB light strip, along with other lighting units, provides illumination within the tunnel, adjusting its brightness based on the detected ambient light level. When a vehicle suddenly stops on the right side of the tunnel, the pressure sensor detects the pressure exerted by the vehicle. At this point, the timing module begins timing. When the preset duration is reached, the controller controls the projector to project a warning pattern onto a light screen and changes the color of the RGB light strip to warn following vehicles. Alternatively, after parking on the roadside, the driver can activate the alarm using the alarm button. Upon pressing the alarm button, the controller again projects a warning light screen and changes the color of the RGB light strip. The brightness of the RGB light strip is adjusted based on the detected vehicle speed. Simultaneously, a buzzer sounds an alarm to alert following vehicles that a vehicle is stopped ahead and needs to swerve to avoid a collision.
