The Hong Kong-Zhuhai-Macao Bridge, a marvel of modern engineering and one of the "Seven Wonders of the Modern World," spans 55 kilometers and was officially illuminated on December 30, 2017. This marked the completion of its entire power supply and lighting system, paving the way for full traffic operations. Among the key players in this groundbreaking project is Shanghai Sansi Electronic Engineering Co., Ltd., a leading Chinese company specializing in LED technology. Their role in supplying all the bridge's lighting systems has placed them at the center of attention within the global LED industry.
The bridge, known as a combination of "bridge-island-tunnel," is a feat of engineering that includes the world’s longest sea-crossing bridge and the longest immersed tunnel. It also stands as one of the most complex and costly projects in China’s construction history. The exclusive supply of LED lighting products by Shanghai Sansi for the entire bridge not only highlights their technological prowess but also showcases China's growing influence in global infrastructure development.
Shanghai Sansi worked closely with project stakeholders to ensure their lighting solutions met the highest standards, especially considering the harsh marine environment, including salt spray, vibration, extreme temperature changes, and typhoons. Through extensive research and testing, they developed cutting-edge LED products such as ceramic street lights, tunnel lights, variable information boards, landscape lights, RGB color searchlights, and maintenance bulbs. These innovations are equipped with intelligent control systems and represent some of the most advanced technologies in the world.
Among the standout products used on the bridge is the **LED Ceramic Modular Street Light**, developed under the national "863" project. This light uses high-power LED units, a unique lens design, and honeycomb convection ceramic heat dissipation technology. It offers high light efficiency, low light decay, and up to 50% energy savings compared to traditional sources. Its durability in harsh conditions makes it a true "black technology" in street lighting.
Another notable product is the **Think LED Tunnel Light**, which features patented reflective illumination technology. Designed to provide comfortable, glare-free lighting while meeting various optical distribution needs, it has become a benchmark in tunnel lighting.
The **LED Variable Information Board** is another flagship product from Sansi, with nearly 20 years of industry leadership. For the Hong Kong-Zhuhai-Macao Bridge, new materials and technologies were added to enhance resistance against salt, UV rays, and extreme temperatures, ensuring reliable operation of traffic guidance systems.
The **LED Landscape Lighting** features a honeycomb structure for reduced wind resistance and efficient heat dissipation. With RGB color-changing capabilities, it adds a stunning visual effect to the bridge, making it a highlight of the project.
Finally, the **LED Maintenance Bulb** combines ceramic heat dissipation, impact resistance, and long life, offering reliable support for daily lighting operations. Its soft, comfortable light improves maintenance efficiency and is considered a top-tier solution for bridge maintenance.
With over 25 years of experience, Shanghai Sansi has grown into a global leader in LED displays, lighting, and smart city solutions. The company employs more than 2,000 people, including nearly 500 R&D professionals. It holds significant market shares in areas like highway information displays, subway lighting, and tunnel lighting across China.
Internationally, Sansi has made a name for itself. In New York's Times Square, 60% of the ultra-high-definition screens are from Sansi, recognized for their exceptional performance. They’ve also supplied major projects like the Xichang Satellite Launch Center and the 2010 Shanghai World Expo.
In addition to large-scale projects, Shanghai Sansi is actively involved in smart city initiatives. Their LED Smart Street Lights have been deployed in cities like Wuning and Ruijin, using big data, IoT, and cloud computing to build sustainable urban environments.
Through innovation, quality, and global recognition, Shanghai Sansi continues to shape the future of lighting and smart infrastructure around the world.
