LED lighting is helping a residential neighbourhood in southern Germany to reach its goal of eliminating non-renewable energy sources by 2030.
Zauberwinkel, not far from Munich in the German state of Bavaria, is a new residential suburb whose planners are prioritising sustainability and climate protection. As part of the emphasis on energy efficiency, public areas of the suburb have been designed with LEDs in mind.
The lighting complements the planners’ sustainable design for the area, which also includes a geothermal system that supplies the entire neighbourhood with thermal energy via a remote heating network. All single-pitch roofs point south to facilitate solar energy systems.
Six main roads and several residential streets are lit with pole mounted luminaires from We-Ef. On main roads the mountings are six metres high and the luminaires are relatively high powered at 59W to ensure adequate light levels.
In areas where residential streets adjoin squares, playgrounds and pedestrian pathways, the mountings are five metres high. On other residential streets the luminaires are four metres above the ground and use 29W.
All the luminaires are fitted with lenses for side throw light distribution to meet local standards for uniformity and glare reduction. Thermal sensors monitor the temperature directly on the LED boards, dimming luminous flux to 50 per cent if a preset temperature is exceeded.
