"Light can help to reduce tension by creating a pleasant atmosphere. We wanted to use light to put patients at ease," says Dr Westhaus. People deal with anxiety in different ways, so the lighting had to be geared to the needs of the patients – as well as the medical personnel – in a flexible manner. Philips’ AmbiScene flexible lighting concept is based on the fact that lighting is one of the factors that most affects how we feel – both physiologically and psychologically. That is why, with this concept, the colour and intensity of the lighting can be adjusted.

By simply refurbishing the Pont de la Guillotière bridge with Philips CitySoul luminaires including CosmoPolis lamps and gear, the city of Lyon has reduced energy consumption on the bridge by almost 50%, thus helping to lower CO2 emissions.
