Sansi LED: Sustainable LED Lighting and Integrated LED Display

Tunnels serve as crucial nodes in modern transportation networks. The safety, reliability, and energy efficiency of their lighting systems are directly related to driving safety and operational costs. Among the various lighting solutions, Shanghai Sansi Electronic Engineering Co., Ltd. (hereinafter referred to as "Sansi") has leveraged 32 years of technological accumulation and innovative practice to create LED tunnel light series products with superior performance. With six core advantages, Sansi has set industry benchmarks and provided better options for tunnel lighting globally.

Technical Advantages: Defining a New Standard for Tunnel Lighting

High Efficiency, Energy Saving, and Ultra-long Lifespan

l Adopting reflective lighting technology, the lights emit softly and evenly, avoiding glare and enhancing driving comfort. Combined with an intelligent dimming system, overall energy consumption is reduced by 50%.

l Ceramic heat dissipation technology ensures the longevity of the luminaires, reducing maintenance frequency in harsh environments such as high altitudes and extreme cold.

Breakthroughs in Environmental Adaptability

l With an anti-salt fog coating and an aluminum alloy enclosure design, it can withstand typhoons, dust storms, and extremely cold climates down to -30°C, with a failure rate below 0.5%.

l Special optical structures eliminate glare, with a color rendering index above Ra80 and a 40% improvement in light uniformity, reducing driver visual fatigue.

Intelligent Control and Safety Upgrades

l Equipped with the StarRiver Pro visual monitoring platform, it supports remote dimming, automatic fault alarms, and multi-device linked management, improving operation and maintenance efficiency by 60%.

l  The emergency lighting system responds in less than 0.1 seconds, ensuring continuous illumination in cases of tunnel power outages or accidents, enhancing evacuation efficiency.

Benchmark Cases: Witnessing Value through Technology Implementation

Shanghai Beiheng Tunnel

Deploying reflective LED tunnel lights (C0810-XC series), it achieves a "seeing light without seeing the lamp" effect through diffuse reflective surface light sources. With an average daily traffic volume exceeding 100,000 vehicles, the accident rate has decreased by 25% year-on-year.

Jinan Yellow River Tunnel

Sansi provided tunnel lighting, landscape lighting, and dome display products and solutions for the Yellow River Tunnel. Multiple innovative technologies, products, and system design schemes have safeguarded the construction and operation of the "First Tunnel of the Ten Thousand Li Yellow River."

Hong Kong-Zhuhai-Macao Bridge Subsea Tunnel

Adopting salt fog corrosion-resistant luminaires and seamless waterproof structures, it has operated continuously for six years without major faults, with light decay rates remaining stable.

Industry Influence: Technology Driving Ecological Co-construction

Sansi's tunnel lighting solutions have served more than 2,500 tunnel lighting projects. Its technological achievements cover scenarios such as urban traffic, high-altitude highways, and subsea tunnels, promoting the construction of a tunnel lighting system integrating "safety + energy saving + intelligence."

Looking ahead, Sansi will continue to explore the deep integration of AI algorithms and lighting control, expanding smart urban transportation networks and emergency management scenarios, and providing better solutions for modern transportation infrastructure construction.
