Shanghai Yingbin 3rd Road Tunnel has been a crucial passage through the Hongqiao hub since the beginning of 2011. Every day, thousands of vehicles pass through this tunnel, and many drivers have been using it for over six or seven years. What stands out most is the comfort provided by the tunnel’s lighting system. The illumination is gentle, not glaring, and the lights have remained in excellent condition with very little damage over the years.
This three-way tunnel lighting system, which ensures a smooth and safe driving experience, is actually a widely used advanced technology across China. The tunnel, which stretches 2,862 meters in length, is located on the southern side of Hongqiao Airport. It serves as one of the most direct and convenient routes between the East and West Terminals of the airport, as well as connecting the Hongqiao Hub to surrounding areas and the city center.
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, providing a consistent and comfortable glow that guides drivers safely through the tunnel.

The unique reflective technology used in these LED lights plays a key role in improving visibility and safety. Unlike traditional lighting, which can cause glare and discomfort, the secondary emission technology of Shanghai Sansi ensures even light distribution. This creates a soft, uniform illumination that reduces eye strain and enhances driver comfort.

This innovative lighting solution has proven its reliability over time. The Yingbin 3rd Road Tunnel has been operating smoothly for over six years, while the Dalian Road Tunnel has been in use for five years. The design includes efficient heat dissipation and self-developed power supplies, ensuring a long service life of up to 50,000 hours.
Additionally, the energy consumption of these LED lights is reduced by 40% to 50% compared to traditional lighting systems. The intelligent control system allows remote monitoring and multi-level dimming based on traffic flow and time of day, further enhancing energy efficiency.
