In 2015 Arianna contributed to the improvement of the section of the A3 Salerno-Reggio Calabria motorway by lighting the Galleria Serra Spiga, in the province of Cosenza.
The lighting system is constituted by reinforced and permanent lighting. The first one, thanks to a counter-beam optics with superior lighting engineering features, is designed from a viewpoint of energy efficiency and safety.
Permanent lighting, on the other hand, through the use of Arianna's patented technology, produces a glare level of just one-fifth of the values required by the standard, which allows for high visual comfort. The technology used also allows high performance in terms of interdistance.
TECHNICAL DATA SHEET
The tunnel, which is approximately 600 metres long and consists of two one-way tubes with two traffic lanes and one deceleration lane, was illuminated by the installation of 552 Teseo and Snell luminaires for the reinforcement lighting and 152 Snell luminaires for the permanent lighting, which allow 90% uniformity, thus ensuring full safety for motorists.
