Royal Philips Electronics (NYSE:PHG, AEX:PHI) has provided LED lighting to improve the safety and energy efficiency of the Hardbrücke, a bridge in central Zurich, Switzerland.
The Hardbrücke project is reportedly the largest LED installation in Switzerland. The underside of the 2.3-km bridge is lit with 1750 LEDline2 luminaires. These require 25 kW for 1,654 hours a year, or 41,000 kWh/yr in total.
Going into the project, the main goal was to upgrade the lighting under the bridge and provide greater security for pedestrians. The lighting system took into consideration users of the bicycle and pedestrian paths as well as a newly laid S-Bahn rapid-transit rail line and an additional public-transportation lane.
Koffer2 luminaires are used on top of the bridge, reducing Zürich’s energy requirements from 32 kW to 21 kW (savings of 42,800 kWh/yr).
Other benefits of the new lighting scheme include much longer service lifetime and reduced maintenance requirements.
The 40-year old bridge in the heart of Switzerland’s biggest city is the main connection between the north and the south, as well as providing connections to other parts of the country. For the approximately 70,000 vehicles that travel across the bridge daily, security and functionality are paramount.
Together with the required renovation of the bridge, the municipality of Zürich chose to renew its lighting with the intention of reducing energy costs, service costs and light pollution. Additionally, Zürich officials sought to shape the night view of the city and improve the quality of life of its residents.
