Black Forest LED Network Progress Report
December 2012 | A Play of RGB Colours Alights St. Georgen's Market Square
The ongoing LED project "Cities and Towns in a New Light" took still another step toward completion with the installation of eight RGB LED illuminating columns on St. Georgen's market square. The Hess LED VIGO columns, placed in pairs at each of the square's four entrances, have a colourful way of attracting attention. Besides being highly energy-efficient and functional, the luminaires' vibrant, changing colours make them useful, decorative elements for the urban public realm.
The unusual lighting is quite popular with St. Georgen's population. "It is very well received and it upgrades the square," says City Architect Reinhard Wacker. Since the illuminating columns are connected to the city's lighting system, they remain on throughout the night.
Successful Completion of the Project to Convert Lighting to LED
St. Georgen and its partner cities and towns in the Black Forest LED Network, Königsfeld, Villingen-Schwenningen and Mönchweiler, were together one of ten winners in 2010 of BMBF's “Cities and Towns in a New Light” competition. The initiative provides support for selected municipal lighting projects to convert from obsolete lighting to energy-efficient LED technology.
That LED lighting solutions are suitable for more than just street and open space lighting is evident from the diverse range of LED lighting projects realised in St. Georgen's partner cities and towns. In Königsfeld, for example, the town green's entire lighting was converted to LED lighting, and, in Villingen-Schwenningen, Hess' LEDIA LED handrail lighting fixtures uniformly illuminate a bridge over the Brigach River.
March 29, 2012 | The Lights Go on with LED Lighting in Königsfeld's Park
On March 29, 2012, Mayor Fritz Link pushed the switch to turn on the new lighting in Königsfeld's Kurpark. With the 63 new TARO LED illuminating bollards and 23 Ravenna LED in-ground luminaires to illuminate the trees, the park now has a completely different atmosphere, one that is more attractive with significantly increased comfort and improved safety for frequenters of the town's green heart.

November 10, 2011 | Photometric Measurements in St. Georgen
After the installation in St. Georgen of the new LED luminaires on Gerwigstraße and at the Marktplatz square, research fellows and students of Furtwangen University of Applied Sciences took photometric measurements and asked residents and people on the street about their opinion of the new lighting.

July 12, 2011 | New Handrail Lighting Fixtures Installed on the Brigach Bridge
After 14 months, the project was completed and Villingen-Schwenningen's mayor, Rupert Kubon, opened the Brigach bridge up to use by the public. The bridge refurbishment was extensive and included a completely new lighting system. The new lighting, HESS' LEDIA GL lighting fixtures, drastically cut energy use by 66 %.
March 31, 2011 | Installation of RESIDENZA Luminaires Completed in Schwenningen
The retrofitting of outdated street lighting in Schwenningen's Karlstraße has been completed. Pole bracket lighting fixtures were replaced with RESIDENZA pole top mounted LED luminaires.

March 24, 2011 | Test Measurements Taken from New LED Lighting at Münsterplatz in Villingen
Paola Belloni, professor at Hochschule Furtwangen, along with her colleagues, students, and in cooperation with TU Darmstadt, a polytechnical university, is responsible for the scientific aspects of the Black Forest LED Network's activities. During the 18 months of the projects' implementation, she is taking measurements to assess the qualitative and quantitative effects of the new lighting. This took place today on Villingen's Münsterplatz. Pedestrians were also polled to determine the public's reaction to the new lighting. Upon completion of the work to convert the lighting to LED, the results will be published in a booklet, which will serve as guide for cities and towns in converting to the new technology.

March 10, 2011 | Zinzendorfplatz in Königsfeld in a New "LED" Light
The new LED lighting at the Zinzendorfplatz plaza in Königsfeld was put into operation at a celebration featuring Anette Schavan, Federal Minister of Education and Research.

February 21, 2011 | Photometric Measurements Taken in Königsfeld
TU-Darmstadt assists the municipal competition with scientific analysis. Together with the Hochschule Furtwangen, its Network partner, the TU-Darmstadt will be performing before and after measurements and a survey of the adjacent residents.

February 9, 2011 | Retrofitting the Vintage Lighting at Villingen-Schweningen's Münsterplatz
The LED lighting installed at the Münsterplatz in VS-Villingen demonstrates clearly that the new LED technology and older luminaire designs are superbly complimentary. HESS' cLED module is ideally suited for use in period luminaires and its appearance is very reminiscent of a vintage light source, preserving the luminaire's retro look. The module's warm light colour of 3000 kelvin produces a very pleasant atmosphere, which is expected and only fitting for such luminaires.

February 8, 2011 | LED Lighting in the Town of Mönchweiler
Seventy-three streetlights in Mönchweiler's Egert Industrial Park have been retrofit with the latest LED light engines. Mönchweiler is the first municipality in Germany to install state-of-the-art LED technology in luminaires located in an industrial area. Thanks to the new technology, lighting unit wattage could be reduced from 70 to 46 watts/unit in the larger units and 50 to 36 watts/unit in the smaller units, providing significant savings.
