Shanghai Yingbin 3rd Road Tunnel has been a vital passage through the Hongqiao hub since the beginning of 2011. Every day, thousands of vehicles pass through this tunnel, connecting different parts of the city with ease. Many drivers who have used the road for over six or seven years often mention that the lighting system is one of the most comfortable features they’ve experienced. The tunnel’s illumination is neither too bright nor glaring, and the lights remain in excellent condition despite years of use. This seamless lighting experience is made possible by advanced tunnel lighting technology that is now widely implemented across China.
The tunnel stretches 2,862 meters long and is located at the southern side of Hongqiao Airport. It serves as a key connection between the East and West Terminals of the airport and acts as a dedicated channel for passengers traveling between the Hongqiao Hub and the central city. A total of more than 3,000 lighting fixtures are installed throughout the tunnel, all of which are Shanghai Sansi LED reflective tunnel lights. These lights are placed every two meters, creating a consistent and gentle glow that guides drivers safely through the tunnel.
The reflective technology used in these LED tunnel lights plays a crucial role in improving driver comfort and safety. Instead of directly emitting light, the system uses secondary emission to reflect and distribute light evenly along the tunnel. This ensures a soft, uniform illumination that reduces eye strain and minimizes glare, making driving safer and more pleasant.
The Shanghai Sansi LED Reflective Tunnel Light has been successfully deployed in several major tunnels across the country. For instance, the Dalian Road Tunnel has been operating smoothly for over five years, and the Yingbin 3rd Road Tunnel has maintained stable performance for more than six years. The design includes efficient heat dissipation and a self-developed power supply, ensuring a long service life of up to 50,000 hours. Additionally, the system consumes 40–50% less energy compared to traditional lighting sources, and it can be remotely monitored and adjusted based on traffic flow and time of day, enhancing energy efficiency further.
This world-class lighting technology is now being applied in numerous tunnels and underground stations nationwide. From the Jiangxi Jingying Expressway to the Shaanxi Xiaoxiao Expressway, and even in subway systems in cities like Shenzhen and Hangzhou, Shanghai Sansi's reflective LED lighting is making a significant impact. As more cities adopt this innovative solution, the future of tunnel and underground lighting looks brighter and safer than ever before.
