Petra Energia/Solar & hybrid lamps/Bochnia

Our next realization, hybrid beacons with power for active signs for Skanska.

Hybrid beacons with power supply for active signs

Project background:

As part of the modernization of Road No. 965 between Bochnia and Drwinia, pedestrian crossings at sensitive points had to be illuminated.

How it was implemented:

The system has been set up in Bochnia, and 6 pedestrian crossings on Road 965 have been illuminated. In this implementation, we used hybrid lamps that work with the power grid. It is worth noting that in this way we achieve significant energy savings over traditional networked lanterns with LED fixtures. In addition, the lanterns give a steady stream of light, regardless of the season.

Also used were luminaires with dedicated optics with asymmetrical distribution designed for pedestrian crossings.
