La Pepa Bridge - cadiz
Tue 11th October 2016
The Constitution Bridge of 1812, also known as the La Pepa Bridge, was opened on 24th September 2015 and is currently the tallest bridge in Europe, the second tallest in the world. The bridge spans the Bay of Cadiz, connecting Cadiz with Puerto Real and measures 3,092 meters long, 185 meters high and 36.85 meters wide. It has two lanes of motorway running in each direction and an additional two lanes reserved for metropolitan public transport such as the new train system and is crossed by 100,000 vehicles per day.
All of these metrics put the bridge at the forefront of European infrastructure and places the city of Cadiz as a modern player in international engineering. Given the bridge’s capacity and usage, it was very important to that the lighting provided was of suitable quality and energy efficient. It was also necessary for the maintenance of the lighting installation to be simple and easy to access.
The Holophane V-Max and T-Max luminaires both meet these requirements on all fronts. With their features of modularity and easy access to equipment, they are ideal luminaires to work as a system for the efficient operation of the entire lighting system.
The V-Max luminaire was used for the main bridge carriageways. V-Max has a luminous flux ranging from 1,000 to 34,000 lm with efficiencies of up to 132 lm/W. The T-Max luminaire was used for the undercarriage of the bridge. The luminaire has a luminous flux range from 6,000 to 40,000 lm, with efficiencies of up to 114 lm/W.
Both of these luminaires have a lifetime of over 100,000 hours and both are controllable, providing additional energy savings and maximising the performance of the luminaires.
