Reduce light pollution by 70% - with Eagle Eye Zhaga

The municipality of Vuadens in the canton of Fribourg was looking for a way to reduce light emissions on an access road in a residential neighborhood so as not to disturb residents with unnecessary light. At the same time, the energy consumption of the lights on the "Route des Colombettes" should be reduced.

The decision was made to use dynamic, motion-dependent lighting control with the Eagle Eye Zhaga radar sensors. The sensors could be mounted and put into operation by the Groupe E in no time directly on the Zhaga interface of the existing DigiStreet lights . The system was convincing because detection is more accurate than with conventional PIR sensors and installation was very simple thanks to the standardized interfaces on luminaires and sensors.

The evaluation of energy consumption since commissioning in February 2020 shows that the luminaires had to be dimmed up less than 30% of the time. This has not only saved energy, but at the same time reduced light pollution and increased the quality of life in the residential neighborhood.
