Motion-sensing LED light fixtures were recently installed in a University of California parking structure, according to LEDs Magazine. Unlike most motion-detecting lights, these new LED lights get brighter instead of merely turning on.
On January 12, the University of California Davis’ California Lighting Technology Center unveiled 50 new LED parking lot light fixtures with motion sensors that trigger increased brightness. The fixtures were placed in the center’s South Entry Parking Structure. The LED lights feature activity-sensing technology that provides enhanced nighttime visibility and reduces energy consumption by up to 80 percent compared with the metal-halide fixtures previously used in the parking structure.
“Even at half power, the LED fixtures are delivering plenty of light to the space. We may be able to cut levels further, saving even more electricity and lengthening fixture lifetimes,” said Michael Siminovitch, director of UC Davis’ California Lighting Technology Center.
The January 12 unveiling was the result of nearly two years of development and field testing. The concept behind the new LED technology was improved safety. When motion is detected and the higher light mode is activated, the change in the visual environment alerts people nearby. Drivers, pedestrians, and security agents now have an indicator when there is activity in the area.
