What is the tunnel external illumination detector?

Tunnel lighting is different from highway, tunnel lighting needs to run continuously in all-weather, 24 hours to ensure good lighting inside the tunnel. Compared with lighting in other places, tunnel lighting needs higher reliability and durability to cope with long-term use and high load work.

And the design of tunnel lighting should take into account the visual effects and safety of drivers and pedestrians. Proper lighting brightness and uniform distribution can provide a clear visual environment, reduce visual fatigue and visual impairment, and improve the driver's alertness and responsiveness. In addition, the brightness difference between the inside and outside of the tunnel is large, and the transition and adjustment of the light need to be considered to ensure smooth transition and comfort when entering and leaving the tunnel. Proper contrast can help drivers and pedestrians better discern roads, signs, and other traffic elements. In general, tunnel lighting needs to meet special requirements when designed and implemented to ensure good visual effects, safety and reliability.

Tunnel external illumination detector is a special equipment for monitoring tunnel brightness, which provides the best value for tunnel lighting. It is designed in accordance with the "Highway Tunnel Ventilation and Lighting Design Code", installed on the wall of the designated area in the tunnel, the height of about 4m must be maintained, the distance from the tunnel entrance is greater than 10m, the measurement range is 0~7000cd/m², the measurement error is ±1%.

Tunnel external illumination detectors can help engineers and designers assess the quality of tunnel lighting and make necessary adjustments and improvements based on the measured results. By accurately measuring and analyzing lighting parameters, a safer, more comfortable and efficient tunnel lighting environment can be provided.

Tunnel external illuminance detector is an instrument used to measure the external environmental illuminance of the tunnel. Its role is to assess the lighting level and light distribution outside the tunnel to ensure good lighting in the tunnel and surrounding areas.

By measuring the illumination value of the external environment, the tunnel external illuminance detector can help determine whether the lighting intensity around the tunnel meets the standard requirements. It can provide accurate illuminance values to help engineers and designers make reasonable lighting planning and design. By using the tunnel external illumination detector, the lighting situation of the tunnel area can be monitored in real time, and the problem of insufficient or excessive lighting can be found and solved in time.

In short, the role of the tunnel external illuminance detector is to provide accurate illuminance measurement for the tunnel area, help ensure appropriate lighting levels, and improve traffic safety and driving comfort.
