Sansi LED: Sustainable LED Lighting and Integrated LED Display

Tunnel lighting is crucial for ensuring driving safety, but achieving safety while also being energy-efficient and effective remains a challenge. Modern tunnel lighting technology addresses these issues through innovative designs. Recently, Sansi participated in the construction of the Yindu Road Tunnel, which has officially opened. This article will provide a detailed explanation of how to achieve safe, energy-efficient, and effective tunnel lighting by combining the case details.

Challenges of Tunnel Lighting: Safety, Energy Efficiency, and Effectiveness

1. Solving Visual Discomfort and Safety Risks

The light intensity differences at tunnel entrances and exits can cause “black hole” or “white hole” effects, increasing visual discomfort for drivers and potentially leading to accidents.

2. Improving Lighting Uniformity and Comfort

Traditional lighting systems may result in uneven brightness in the tunnel, affecting visibility in different areas and complicating drivers’ judgments.

3. Energy Efficiency and Low Maintenance

Tunnel lighting systems need to run for extended periods at high intensity, which leads to increased energy consumption and maintenance costs. Traditional lighting systems tend to have low energy efficiency and short lifespans, creating additional operational burdens.

Solution: Innovative Tunnel Lighting in the Yindu Road Cross-River Tunnel

The Shanghai Yindu Road Cross-River Tunnel officially opened on December 27, 2024. The tunnel is approximately 3.8 kilometers long, connecting the Xuhui, Minhang, and Pudong districts, primarily linking Xuhui and Minhang across the Huangpu River. The tunnel features a dual-layer design, with the lower tunnel measuring 2.7 kilometers in length and a speed design of 60 km/h, while the upper tunnel spans 1.8 kilometers with a speed design of 40 km/h. The tunnel’s opening will effectively ease traffic pressure at the Xinzhuang Interchange and the western and southern sections of the S20, providing significant support for the smooth flow of traffic in Shanghai.

At the tunnel’s entrances and exits, Sansi effectively addresses the light intensity difference through its color temperature alternating design, which reduces the “black hole” and “white hole” effects. This intelligent temperature adjustment ensures a smooth light transition, greatly enhancing visual comfort and safety for drivers.

To improve lighting uniformity within the tunnel, Sansi employs reflective lighting technology. This innovation eliminates areas with inconsistent brightness, creating a uniform light distribution that helps drivers maintain a consistent visual experience. By reducing glare, this technology enhances driver reaction times and judgment, offering a more comfortable driving environment compared to traditional lighting systems.

Sansi’s LED ceramic heat dissipation technology significantly boosts the heat dissipation performance of tunnel lighting, ensuring stable operation during long periods of high-intensity use. This technology not only extends the lifespan of the lights but also reduces energy consumption and maintenance costs.

The integration of an intelligent traffic system optimizes traffic management within the Yindu Road Cross-River Tunnel. By collecting real-time traffic data, smart devices provide timely guidance to drivers, helping them make quick decisions to avoid accidents and congestion. Additionally, the system features real-time monitoring and management, ensuring smooth traffic flow both inside and outside the tunnel

The successful application of Sansi’s innovative lighting technology in the Yindu Road Cross-River Tunnel demonstrates the significant potential and practicality of modern tunnel lighting solutions. By combining color temperature alternating design, reflective lighting technology, LED ceramic heat dissipation technology, and intelligent traffic systems, Sansi has effectively addressed several key challenges in tunnel lighting. The result is a major improvement in the driving experience for Shanghai residents, while also achieving substantial energy savings and lowering operational costs.

As urban transportation continues to evolve, tunnel lighting systems will continue to develop in the direction of greater intelligence, energy efficiency, and effectiveness. For those planning or renovating tunnels, integrating innovative lighting technology and intelligent systems is undoubtedly the key to enhancing project quality and operational efficiency.
