Application of Intelligent Lighting Control Systems in Metro Stations:

Automatic Dimming

At entrances and hallway areas, illuminance sensors are installed to monitor natural light levels and pedestrian movement, allowing for intelligent lighting control and brightness adjustment. For example, when there is sufficient natural light or no people are detected, the system can automatically turn off or dim the lights. Conversely, during nighttime or when people are detected, it can automatically turn on or brighten the lights, ensuring adequate illumination while saving energy.

For instance, at metro platform screen doors, smart radar detectors are installed. When a train is about to arrive, the lights near the doors brighten automatically. After the train departs, the lights revert to energy-saving mode, providing an intelligent and user-friendly lighting experience while significantly reducing electricity and maintenance costs, achieving both efficiency and energy savings.

Scene Control

Various scene modes can be preset based on the metro’s operational needs, such as:

  • Peak Mode: All public area lights in the concourse and platform levels are fully on.
  • Energy-Saving Mode: Some lights are turned off or dimmed.
  • Cleaning Mode: Only a few lights or those in cleaning areas are turned on.
  • Shutdown Mode: All normal public area lights are off, leaving only emergency lights on.

Fault Monitoring

The system can monitor the operational status of lighting equipment in real-time, detecting issues like whether a COMLED batten light is damaged or if the power supply is normal. This allows for timely maintenance and repair, improving equipment reliability and maintenance efficiency.

Application of Emergency Evacuation Lighting Systems in Metro Stations

Emergency Lighting Fixtures

In emergencies such as fires, power outages, or earthquakes, emergency lighting fixtures immediately activate, providing essential illumination for passengers and staff. This ensures they can clearly identify safe exits and evacuation routes in smoke, darkness, or chaos.

Emergency Sign Lights

Emergency sign lights, such as direction indicators and exit signs, clearly mark evacuation routes, helping people evacuate quickly and orderly.

Intelligent Monitoring and Management

Modern metro stations typically use centralized control designs for their emergency lighting systems. The status of all emergency lights can be managed through an intelligent system, facilitating routine maintenance and rapid response in emergencies. In a crisis, the system intelligently controls the operation of indicator lights. Controllers use a bus network to monitor each terminal in real-time, automatically sending commands to each terminal. The terminals then perform actions such as flashing, changing direction, or turning lights on and off, guiding people safely to evacuation points.
