Tunnel external brightness detector: Create a good visual environment to ensure that vehicles can safely pass through the tunnel. [Model recommendation: TH-DW1, IoT integrated device, customized service supported by Yunjing Tianhe]In tunnel traffic scenarios, the "black hole effect" and "white hole effect" caused by the large difference in brightness between the inside and outside of the tunnel when vehicles enter and exit the tunnel are one of the main hidden dangers that threaten driving safety. As the "sensing pioneer" of intelligent lighting control system, the brightness detector outside the tunnel captures environmental parameters such as natural light intensity, color temperature, and weather changes in real time through high-precision optical sensors, providing dynamic adjustment basis for tunnel entrance lighting. When the external sunlight is strong, the detector transmits high brightness data to the control system, driving the entrance lighting to automatically enhance and gradually weaken the visual impact of the "black hole effect" on the driver; When the external light is dim or in rainy or foggy weather, the system reduces the entrance lighting intensity to avoid temporary blindness caused by the "white hole effect". This "perception response" closed-loop mechanism not only shortens the visual adaptation time of drivers, but also creates safe and comfortable traffic conditions through precise light environment transition design, building a digital defense line based on environmental perception for tunnel traffic safety.

Product Overview:

Highway tunnels are special sections of highways, with narrow spatial environments, large variations in lighting, and unclear visibility as a special tubular structure. Unlike the bright and spacious roads outside the tunnel, the process of vehicles entering and passing through the tunnel is a process of entering from the bright into the black hole, and then moving from the black hole to the bright. The process of transitioning from light to dark or from dark to light requires an adaptation process. During this adaptation process, drivers find it difficult to identify road targets or objects inside the tunnel, resulting in visual psychological barriers or obstacles that make driving appear unsafe. The purpose of tunnel lighting is to create a good working visual environment quality inside the tunnel, ensuring that vehicles traveling during the day and night can safely approach, pass through, and pass through the tunnel at the designed speed.

Tunnel light intensity detector is an efficient lighting control system designed to address visual adaptation issues caused by differences in brightness and darkness inside and outside tunnels. In response to the requirements for lighting control in domestic highway tunnels, our company has developed an in tunnel illumination detector and an out of tunnel brightness detector to meet market demands. Its overall design can meet the requirements of harsh outdoor working environments, with high reliability and low maintenance, microprocessor technology, digital operation, and easy installation and debugging. This product aims to improve the scientific and energy efficiency of tunnel lighting by accurately measuring the brightness of the tunnel entrance and automatically adjusting the internal lighting, ensuring driving safety requirements and energy-saving effects, while complying with the requirements of the "Design Specification for Highway Tunnel Ventilation and Lighting".
