Light & Health – circadian lighting

More light – and just the right light too! An ingeniously senior-friendly lighting solution for the Antonistift retirement home in Bamberg

Our perception of light and dark, cold and warmth, and the changing seasons has enabled us to develop a complex system of inner clocks known as the circadian system. Daylight constitutes the natural clock for our daily rhythm. Dynamic management of artificial light with daylight-dependent variable blue light in the visible spectrum can help to strengthen our circadian system and thus improve our quality of life.

This phenomenon plays a key role in the healthcare sector, as can be seen in the renovation of the Altenburgblick retirement home, where some 60 to 80 percent of residents suffer from dementia. Circadian light reduces the typical symptoms of this disorder such as aggressive behavior, disorientation, and sleep disturbance.

To achieve these circadian-lighting effects in the Altenburgblick retirement home, Econe Hybridluminaires from RZB Rudolf Zimmermann, Bamberg GmbH were installed. The Econe lights, which have won several design awards, strengthen corridor safety with illuminance of around 1,000 lx. Thanks to their shallow recess depth of only 14 cm, these 885x885mm general-lighting luminaires are particularly suitable for use in renovated retirement homes. At the 2014 edition of the light + building trade fair RZB unveils the suspended, surface-mounted and recessed Econe Hybrid luminaires which are completely fitted with LED (LEDs in both light chambers) and with a translucent frame for the suspended version.

In the Antonistift retirement home daylight is simulated using dynamic mixtures of the available colour temperatures, and the system is controlled by the RZB’s light control +³ Professional Circadian plug and playlighting management system. Moreover, the well thought out lighting design provides excellent work lighting for caregivers, safety and orientation for residents and promotes a congenial atmosphere for all. Circadian lighting solutions will be showcased by RZB from 30 March to 4 April in at the light + building trade show, hall 3.0 D41.
