"Dynamically from 0 to 100% light: commuters should feel safe on the "Voie verte" - and residents undisturbed"
Ensure safety and standards, save maximum energy and minimise light pollution at the same time
The "Green Way" in Bulle (FR) connects the train station with the Planchy-Nord industrial area, an important employment area in the region. The so-called "Voie verte" lives up to its name: Here, the light only comes on when commuters pass it, otherwise it is dark. The 53 or so new Luma Micro luminaires are controlled by Eagle Eye Zhaga radar sensors to maximize energy savings while complying with standards and minimizing light pollution.

What were the requirements of the municipality for the new lighting of the "Voie Verte"?
In principle, there is no legal requirement for lighting on the "Voie verte". However, the municipality decided to install lighting anyway for the safety and well-being of the many commuters. It was important to keep light pollution to a minimum for the benefit of the residents. We were able to achieve this with a low candelabra height, anti-glare louvers and, of course, dynamic lighting control.
You use the Eagle Eye Zhaga motion-dependent lighting control system. Why was this control system chosen?
The path connects the new Bulle train station with the Planchy industrial area over a length of 1.6 km. The majority of the pedestrian flow consists of people who work in the area. Apart from the morning and evening hours, there is relatively little traffic at night. Dimming the lighting down to 0% when the path is not being used by pedestrians was therefore the most environmentally friendly and economical solution.
Care also had to be taken to ensure that trains passing directly next to the "Voie verte" were not detected by the detectors. This works perfectly.
