Lighting conditions in healthcare facilities are governed by stringent lighting standards. In care work that requires precision, illumination must promote alertness and contribute to safety. In clean spaces, luminaires must be easy to clean and they must be protected against moisture and dust. In addition to having to meet strict hygiene-related requirements, lighting has an impact on how the patient experiences the situation and surroundings. At a dentist’s clinic, back-lit nature pictures create a calming and pleasant atmosphere.
