Hong Kong-Zhuhai-Macao Bridge Night Lighting Design Secret

The total length of the Hong Kong-Zhuhai-Macau Bridge is about 55 kilometers. The main project is a combination of bridges, islands and tunnels, totaling 29.6 kilometers, including three navigational cable-stayed bridges in Jiuzhou, Jianghai and Qingzhou, and 19.6 kilometers of non-navigable bridges, 6.7 kilometers. The submarine tunnel, as well as the two artificial islands connecting the bridge and the tunnel, were named one of the "Seven Wonders of Modern International" by the British Guardian.

Against the backdrop of fireworks and lights, the bridge draws a curved curved line in the twilight, like a beautiful string of beads embedded in the ocean.

The night illumination of the Hong Kong-Zhuhai-Macao Bridge is divided into two parts: functional lighting and decorative lighting.

The three navigation bridges in the main scene area have seven towers. Each tower is equipped with dozens of Color-changing led flood lights. The narrow beam projection is used to brighten the facade of the main tower.

The cable-stay night lighting uses a narrow beam of color-changing led flood light to search for each cable, not only to outline the shape, but also to show the tension of the cable and the rhythm of the strings.

The Hong Kong-Zhuhai-Macao Bridge nightscape lighting system uses both daily and holiday lighting forms.

The daily lighting form is mainly white, showing the nature of the bridge and providing the base for lighting. In the course of use, the engineers selected the most advanced dynamic variable frequency lamps in the world to make the bridge lighting more energy-saving and environmentally friendly.

It is understood that the bridge section uses 1280 动态 of dynamic variable frequency lamps, and the distance of the lamps is 35 meters. It can complete other dimming from 0% to 100% according to the requirements of road illumination.

In the form of holidays, the bridge is colored by the Color-changing led flood light to make the sea dragon in this night sky even more sturdy.

How is the planned lighting system controlled?

After three-dimensional modeling skills, the monitoring center carried out a 1:1 three-dimensional simulation of the entire Hong Kong-Zhuhai-Macao Bridge, and completed real-time monitoring of all electromechanical equipment of the entire Hong Kong-Zhuhai-Macao Bridge through tens of thousands of sensors.

Zhang Ping, senior engineer of the transportation engineering system integration of the Hong Kong-Zhuhai-Macao Bridge: "All our transportation engineering equipment and lines are within the supervision scale of our monitoring channel. The supervision point should exceed 100,000 points, click on a certain device, can Jumping directly into the three-latitude model, you can visually see a state and a real-time status of the device."

Not only can the real-time detection of the operation status of all the electromechanical equipment of the bridge, but once the circuit is faulty, the fully automatic protection system will prompt the staff to carry out the accurate fault cleaning solution.

For example, if there is an alarm, it will pop up a corresponding alarm prompt. Prompt the staff to follow up the corresponding fault handling.

In addition, in the submarine tunnel lighting system, the planning concept of seeing the light is not used.

That night, the light of the century was open in the vast ocean, and the “dragon” with curved sea surface became the most beautiful scenery.
