LEDs provide energy-saving period-style lighting for historical alleys in Regensburg

Dec 8, 2009

In Regensburg, OSRAM Opto Semiconductors and Siemens have demonstrated that energy-saving LEDs can provide authentic period-style lighting for a historical centre. The companies have developed a retrofit solution which meets the requirements of a modern lighting system while preserving the atmosphere of a world heritage site. The light sources being used are Golden Dragon Plus LEDs. Discreetly installed in the luminaires prescribed by the Office for the Preservation of Historical Monuments, they target the precise spot they are intended to illuminate, thus avoiding light pollution.

The prototype luminaire permits the replacement of ordinary 90 W mercury vapour lamps with LEDs cutting energy consumption from 90 W to just 42 W. The Golden Dragon Plus LEDs have a color temperature of 3500 K and a color rendering index of 80.The luminaire design is based on a cylinder. Manufactured by the Regensburg branch of Siemens, the prototype can be fitted with different numbers of LEDs on either side as required and so as to produce the desired lighting effect. This allows for completely different light distributions. Up to now, there was an uneven distribution of light, but now a homogenous illumination of around 3 Lux has been achieved.
