This system uses LED lights to mimic natural daylight patterns in patient rooms, rather than the harsh lighting that patients normally experience in wards. Light levels gradually increase to replicate the soft glow of a morning sunrise to the bright light of mid-mornings, and then steadily decrease in the evening. Natural light has been clinically proven to improve patient wellbeing and sleep in clinical trials. http://www.lighting.philips.co.uk/systems/packaged-offerings/office-and-industry/healwell.html
