Sansi LED: Sustainable LED Lighting and Integrated LED Display

Sansi LED Subway Lighting: Redefining Urban Travel Experiences with Intelligent Illumination‌

Shanghai Sansi, leveraging its proprietary LED lighting technology and intelligent systems, continuously provides safe, efficient, and user-friendly lighting solutions for urban rail transit. Through benchmark projects such as Shenzhen Metro and Hangzhou Metro, Sansi empowers subway lighting environment upgrades with innovative technology and scenario-based designs, contributing to the development of smart cities. The following showcases its core value from two dimensions: technological breakthroughs and scene applications.

Core Technological Advantages

‌Reflective Lighting and Anti-Glare Design‌

By adopting reflective lighting technology and eliminating direct glare through secondary optical light distribution, a soft and uniform lighting environment is created. The platform light strips of Hangzhou Metro Line 2 achieve the effect of "seeing light but not the lamp" through this technology, avoiding visual fatigue for passengers and enhancing waiting comfort.

‌

Intelligent Scene-Based Control‌

The self-developed intelligent control system supports dynamic dimming by region and time period. Hangzhou Metro Line 2 has set up five management modes such as "peak mode" and "off-peak mode", achieving precise matching of lighting energy consumption with operational needs.

‌Lifecycle Management System‌

Integrated with equipment health monitoring and fault warning functions, it supports remote real-time viewing of lamp status. Shenzhen Metro Line 2 has implemented preventive maintenance through this system, reducing maintenance costs and ensuring the stability of the lighting system.

‌Scene Innovations‌:

l Cleaning mode automatically increases the illuminance in the working area, ensuring cleaning efficiency and safety.

l Carriage lighting is linked with route information screens, dynamically matching destination-themed lighting effects.

Future Layout: Green Low-Carbon and Digital Twins

Sansi is exploring a photovoltaic-driven subway lighting system, reducing dependence on grid electricity through solar power and energy storage technology. Simultaneously, it is developing a digital twin operations and maintenance platform, which will predict the aging trend of lighting equipment through virtual simulation in the future, enabling an upgrade to "predictive maintenance".

Through the subway lighting practices in Shenzhen, Hangzhou, and other cities, Shanghai Sansi continues to lead the innovation of rail transit lighting environments, infusing urban travel with safety and warmth through technological prowess.
