Tridonic and Rigamonti are among those who have made the tunnel lighter, brighter and safer for the 2,500 vehicles that use it every day
A high-performance lighting system has been installed on the Schallberg tunnel in the Swiss Alps after two and a half years’ of renovation work, designed to modernise the 1970s construction and improve safety for the 2,500 vehicles that use it daily.
A total of 100 transition zone luminaires and 150 interior zone luminaires from Swiss tunnel lighting specialist Rigamonti have been installed with inner workings from Tridonic. Emergency lights on the walls, the escape route lights, the escape route indicators and the escape exit signs are all equipped with LED components from Tridonic.
The 45km long Simplon Pass between Brig and Iselle is one of the most important transit routes in the Swiss Alps. This Swiss national highway route features numerous tunnels, galleries and bridges, most of which have been in operation since the 1960s or ’70s and are now in great need of renovation.
Renovation of the 500m long tunnel at the start of the pass not far from Brig could not be delayed any longer in view of its advanced age. “This was a complete renovation job, involving all the tunnel elements,” said Mark Siegenthaler from ASTRA, the Swiss Federal Roads Office. “Among other things, we repaired the two galleries, built a new escape tunnel, lowered the road in some places to provide adequate clearance for trucks, and put down a new road surface.”
The operational and safety equipment, ventilation system, power supply, control system have all been renewed as well as the lighting. and the lighting All these were once state of the art, of course, but that was back in the 1970s.
The transition zone luminaires in the entrance and exit zones feature new LED modules based on the high-efficiency RLE series and developed specifically for tunnel lighting in accordance with specifications supplied by Rigamonti.
The entrances to and exits from tunnels are high-risk areas for accidents because the lighting conditions change so abruptly. The risk can be reduced, however, with the right artificial lighting.
The new LED solution from Rigamonti for the Schallberg tunnel is a high-performance lighting system that offers a high level of visual comfort and has a positive effect on the sense of safety among vehicle drivers.
The system ensures compliance with the current standards of the Swiss Engineers and Architects Association (SIA) and will lead to a noticeable reduction in energy consumption and maintenance costs. For example, the LED inserts can be replaced without the need for any tools.
Tridonic specifies a life of up to 100,000 hours for the components. This translates into eleven and a half years of continuous operation for the interior zone luminaires.
The Swiss Federal Roads Office ASTRA invests around 30 million Swiss Francs each year on maintenance and optimisation measures at the Simplon Pass, especially in the area of safety, and has completed numerous projects on this route in the last few years.
