On September 27th, the main bridge project of the Hong Kong-Zhuhai-Macao Bridge was completed. The penetration of the main bridge means that the civil works of the Hong Kong-Zhuhai-Macao Bridge is nearing completion, and the construction of traffic engineering including safety facilities, electromechanical, toll, transportation, lighting and communication will soon be ushered in.
With the arrival of this process, Shanghai Sansi will provide a series of LED application products for the Zhuhai-Hong Kong Bridge.
With a total length of 49.968 kilometers, the Hong Kong-Zhuhai-Macau Bridge is the world's longest cross-sea bridge and the largest bridge and tunnel combination project. The Hong Kong-Zhuhai-Macao Bridge can withstand the impact of the 16th-class typhoon, the 8th-level earthquake and the 300,000-ton huge wheel. The designed service life is 120 years, so it was praised by the British Guardian as one of the "Seven Wonders of the Modern World".
Unlike other inland bridge constructions, the Hong Kong-Zhuhai-Macao Bridge spans the Bohai Sea. The bridge faces the harsh environment of salt spray, vibration, typhoon thunderstorms, and large temperature differences between day and night. Construction and transportation facilities have put forward more stringent requirements.

Among the equipments such as roads, tunnels, landscape lighting and traffic instructions, the owner Fanggang Hongqiao Bridge Administration and the mechanical and electrical general contractor China Railway Construction have repeatedly demonstrated, tested and compared, and finally decided all the LEDs of the Hong Kong-Zhuhai-Macao Bridge. Street lights, LED tunnel lights, LED variable information boards, LED landscape lights, and corresponding intelligent control systems are all based on Shanghai Sansi products.
The Sansigang Zhu'ao Bridge project is used for LED streetlights for bridge road lighting. It uses ceramic heat sink and honeycomb convection heat dissipation technology. There is no non-ferrous metal, independent pixels disperse heat, and the heat loss is more thorough. At the same time, it can adapt to the multi-vibration of the cross-sea bridge. The salt spray environment, pressure resistance, corrosion resistance, life and reliability have been qualitatively improved.

The Sansi LED Tunnel Light will provide lighting for drivers in the five subsea tunnels of the Hong Kong-Zhuhai-Macao Bridge. Sansi LED tunnel light adopts reflective LED technology. When the light is not visible, the light is uniform and soft, and it has the characteristics of “anti-glare, waterproof, dustproof, anti-corrosion, anti-wind pressure, anti-vibrationâ€.
Sansi's LED tunnel lights have been widely used in more than 500 tunnels in more than 20 provinces across the country. The Jingdezhen-Yingtan Expressway LED tunnel light project in Jiangxi has been running for nearly 10 years and is still stable and reliable.

LED variable information board is the traditional advantage product of Sansi, leading the industry for nearly 20 years, and has maintained a market share of more than 60% of the domestic road variable information sign (LED variable information board) for a long time.
In the case of the Hong Kong-Zhuhai-Macao project, in consideration of the original technological advantages, Sansi also adopted a number of new technologies and materials to prevent salt spray, vibration, ultraviolet light and high and low temperature, fully guaranteeing the release of traffic information and traffic guidance functions of the bridge. Continuously and steadily running.

In addition to LED street lights, LED tunnel lights, LED variable information boards and corresponding intelligent control systems, Sansi will also provide lighting for the landscape lighting project of the 4 individual islands of the Hong Kong-Zhuhai-Macao Bridge.
