Vienna wants to reduce light pollution. It therefore installs 50,000 LEDs

Vienna wants to reduce light pollution. It therefore installs 50,000 LEDs By 2020, Vienna wants to install LED lights in up to 50,000 hinged lamps. Despite the higher acquisition costs, the city promises long-term savings. In addition, new lights reduce light pollution. The exchange will start in the autumn. It informs the Foreign Office of the City of Vienna.

The exchange will cover a total of 50,000 of 154,000 lamps managed by the City of Vienna through Vienna's Wien Leuchtet. After nearly sixty years, the existing lighting in the hanging lamps over the Viennese streets will replace the LED technology, except for historical areas and protected areas.

"With new luminaires we can achieve energy savings of over 60 percent over the original lamps. This is also a major contribution to climate protection, " says Vienna Vice-Mayor Maria Vassilaka. The current annual consumption of street street lighting in Vienna is 51,800 MWh. In addition, the new technology requires less maintenance, which will bring other savings to the city.

Less light smog

New light sources deliver the same color of light as the original (4,000 kelvin). Thanks to the new technology, staff in the city's public lighting department can better navigate to selected places like transitions or junctions, from which the city hall promises to increase traffic safety. However, the new LED lamps do not emit light on the sides but only downwards. Thanks to this, they produce minimal disturbing light, so there are significantly fewer ambient facades, including windows, and less contributing to light smog.

LED technology comes into public lighting not only in Vienna. One of London's Tower Bridge signs lit up in 2012 with white LED light to celebrate the anniversary of the reign of Queen Elizabeth II. New lighting for the Londoners did not cost even a penny. Thanks to an agreement between London City Hall and the City of London Corporation, the owner of the bridge, it was paid by EDF and GE.

LED technology in public lighting was also tested by the Prague City Hall.
In 2009, several streets in Prague's Smíchov were equipped with LED lights of various companies. The City Hall wanted to test how the Prague people react to the different colors and intensity of light.
