Val Sarentino Tunnel


This years for Arianna starts with the inauguration of the Val Sarentino Tunnel, located along the SS 508 in the province of Bolzano, where the patented LED light fixtures were installed.

The project is composed of two two-way tunnels with a length of respectively 1.5 km and 2 km. In both directions were installed LED luminaires for permanent and reinforcement lighting, so as to ensure a high level of safety and visual comfort for drivers who cross the tunnel, both day and night.

The lighting fixtures installed, Teseo and Titlis, are both covered by the Total Reflection patent, bringing visual comfort and energy savings in the tunnel.

Technical data sheet

The indoor lighting of the tunnels employs a total of 320 Titlis 65W, while each entrance features a maximum of 52 Teseo with power consumption ranging between 45W and 305W.

The reinforcing systems develop for a length of about 330 m since the tunnel entrances using a LED lighting fixtures in counterflow optical (for the first 180 m approximately) and symmetrical (for the remaining 150 m).

The permanent system, instead, is spread throughout the length of the tunnel and use a LED lighting fixtures with symmetric optics and nominal power of 65 W.
