Modern Expressway Tunnel Light Monitoring & Controlling adopt the Loop Dimming System Jun 28, 2021

Automatic LED Outdoor Lighting achieves by Smart Street Light & Tunnel Lighting using the IoT Lighting Technology which are integrated with Motion Sensor and Ambient Sensor for seamless connecting to get maximum energy optimization.

Intelligent Tunnel Lighting Features:

1. Automatic Dimming according to Natural Daylight Intensity detecting Sensor, perfect solution for the Black Tunnel & White Tunnel Effects--Black Tunnel and White Tunnel Syndrome will be completely solvely, especially prevent Vehicle collision or rear-end collision accidents occur at the Tunnel Entrance and the Tunnel Exit area.

2. Linked with the Vehicle Detection Sensor: when a vehicle passes, it is automatically Dimming according to the natural light intensity; when there is no vehicle passes, it returns to a safe illuminance.

Intelligent Street Lighting Features:

1. Automatically Switch On & Off & Dimming the lights according to the Sunset and Sunrise time;

2. Automated Dimming according to Natural Light Intensity, automatic Turn On and Emergency Lighting in abnormal weather (such as Heavy Cloudy Weather, Heavy Rain, Foggy, Snowing, etc.).

3. Warm White & Cool/Nature White CCT colors auto-switching by at Summer Winter, Snowing, Foggy days according to Scene Timing. For example: 2700K CCT in Snowing/Foggy Days, and 4500/5000/6000K in Summer, Autumn seasons.

48 Loop Dimming Controllers + 16,000 units Tunnel Lamps are Controlling

Huiqing Expressway is located in the central part of Guangdong Province. It is an important part of the "Second Horizontal Express" line of Guangdong Expressway Planning Network-Shanzhan Expressway. It starts in Longhua Town, Longmen County, Huizhou City and ends in Taihe Town, Qingxin District, Qingyuan City.

With a total length of 125.28 km, the whole line adopts two-way 6-lanes design standards. There are 5 hubs and 10 (oil field, Nankunshan, Xitou, Sijiu, Sanmen, Longshan, Feilaixia, Huangtengxia, Fengcheng, Tai And) toll booths. The roadbed is 33.50 meters wide and the design speed is 100 kilometers per hour. The bridge-tunnel ratio is up to0 48.8%, and the estimated total investment is about 3.23 billion USD. [1] The Huiqing Expressway was fully started in March 2017, and it is planned to be completed and opened to traffic in 2020. [2]

The Guangdong Provincial Transportation Group announced that the Shantou-Zhanjiang Expressway Huiqing Project (Huiqing Expressway for short) has been completed and accepted and will be officially opened to traffic at 9 am on October 18, 2020. [3]

There are total 48 Loop Dimming Controllers(Loop circuit dimming switches) on this Expressway Tunnel Groups. The Intelligent Street Lighting illuminance sensor will dimming the tunnel lamps automatically to its demand brightness expecttion by detect the Daily Changing Ambient Light Intensity, to keep the light brightness of interior tunnel and exterior the tunnel Linearly smooth transition. When there is no huge difference in brightness,  the  intelligent LED Lighting monitoring and control management sysem will ensure that drivers immediately adapt to the "Black Tunnel and Whitle Tunnel Effect" of the highway tunnel lighting ,to ensure the comfort and safety of drivers to the greatest extent.
