Sansi LED: Sustainable LED Lighting and Integrated LED Display

In the booming development of transportation construction, tunnel lighting is not only a key element in ensuring driving safety but also an important platform showcasing urban quality and technological strength.

Shanghai Sansi Electronic Engineering Co., Ltd. (referred to as "Sansi"), with its profound experience of 32 years in the research and application of smart lighting technology, has shone brightly in the Jinan Yellow River Jiluo Tunnel and the North Extension of Jiluo Road Yellow River Tunnel projects. With its excellent smart lighting solutions, Sansi has endowed this important tunnel with a safe, comfortable, and uniquely aesthetic lighting environment.

Empowering Technology to Build a Safety Line

The North Extension of Jiluo Road Yellow River Tunnel project is a key project in Jinan's transportation construction, with great construction difficulty and high technical requirements, posing extremely stringent demands on tunnel lighting. The Sansi team conducted in-depth research on project needs and tailored a comprehensive and advanced smart lighting solution.

Through scientific and reasonable lamp arrangement design, enhanced lighting is set up in key areas such as the tunnel entrance section, transition section, and exit section, effectively improving drivers' driving safety and visual comfort. At the same time, Sansi's self-developed intelligent lighting control system serves as the "smart brain" for safe tunnel operation. This system can real-time monitor parameters such as traffic flow and illumination intensity inside the tunnel and automatically adjust the lighting brightness based on actual conditions.

The intelligent lighting control system can also real-time monitor the status of luminaires. Once a fault is detected, it immediately issues an alarm, facilitating timely maintenance by repair personnel and providing solid safety guarantees for tunnel traffic.

It is worth mentioning that Sansi has successfully illuminated the "Wanli Yellow River First Tunnel" — the Jinan Yellow River Jiluo Tunnel, the largest diameter under construction in China and the first highway-subway combined tunnel crossing the Yellow River. Its outstanding practice in the North Extension of Jiluo Road Yellow River Tunnel project once again demonstrates Sansi's strong strength and innovative courage in the field of smart lighting.

Intertwining Light and Shadow to Create an Aesthetic Feast

In addition to ensuring driving safety, Sansi also focuses on the aesthetic design of tunnel lighting, striving to create an aesthetically pleasing driving environment for drivers. In terms of landscape lighting, Sansi displays ingenuity, using clever lighting design and control systems to present a dreamy lighting effect on the tunnel ceiling and sidewalls.

- The tunnel ceiling is outlined with soft lighting lines, as if a dazzling galaxy is flowing overhead, bringing drivers a dreamy visual experience.

- The sidewalls feature diversified lighting patterns and color changes according to different areas and themes.

- In some special areas of the tunnel, the combination of lighting and art displays Jinan's historical culture and regional characteristics, allowing drivers to feel the city's cultural heritage during the drive.

This perfect fusion of technology and light not only alleviates visual fatigue caused by driving through long tunnels but also enhances the overall quality of the tunnel, making the North Extension of Jiluo Road Yellow River Tunnel a unique scenic spot under the Yellow River and showcasing Jinan's urban charm and technological strength.

Looking Ahead: Continuous Innovation and Leadership

Currently, Sansi has served more than 2,500 tunnel lighting projects nationwide, including the Shenzhen-Zhongshan Bridge and the Hong Kong-Zhuhai-Macao Bridge, illuminating the way forward for China's tunnels with the light of technology. Its outstanding performance in the Jinan Yellow River Jiluo Tunnel and the North Extension of Jiluo Road Yellow River Tunnel projects demonstrates its excellent strength and innovation in the field of tunnel smart lighting.

Looking ahead, Sansi will uphold innovation, increase investment in research and development, explore intelligent, green, and user-friendly lighting solutions, provide high-quality services for more urban transportation facilities, respond to national strategies, and contribute to the high-quality development of urban transportation.
