Underground parking lot lighting customized LED lights fixtures

Based on the actual lighting and vehicle usage, the day's illumination is divided into several periods. Through software settings, the number of LED lights opening and closing is automatically controlled during these periods. This achieves different illuminance levels in controlled areas for lighting, effectively utilizing light while significantly reducing energy waste, protecting fixtures, and extending the lifespan of LED lights.

Intelligent sensing systems are installed in the fixtures: When there are people in the area, the illumination brightness is set to 100%; when there are no people, the brightness automatically decreases to 10%; if no activity is detected for an extended period, the light flux is reduced to 5%, and the LED lights are fully turned off after a few minutes. This not only meets the requirements of security monitoring lighting but also maximizes electricity savings.

Rhythmic Lighting for Two-thirds Energy Reduction

The "lights on when people are present, lights off when people leave" smart sensing feature utilizes sensors linked to the lights. When these sensors detect people or vehicles, the lighting control system automatically adjusts the lights.

In addition to detecting moving objects, the smart sensing mode can predict the direction of motion, allowing for better adjustment of the light circuits and further savings in lighting costs. in an underground parking lot, when no people or vehicles are detected, the lights' brightness reduces to 10% of maximum; upon detecting movement, the brightness of the lights 30-50 meters ahead (adjustable distance) adjusts to 70% to 100% based on the direction of motion.

Timing and Sensing for Energy Conservation

Combining timing and sensing separates weekdays and weekends, automatically activating or deactivating lights according to preset schedules. Motion sensing control gradually brightens lights in the presence of people and dims them after a delay when no activity is detected.

Energy-saving Lighting Scenes Tailored to Specific Needs
