Colour–dynamic lighting supports the body’s circadian rhythm and the production of melatonin, which is essential for good sleep. This is combined with sensitive lighting design, which creates a safe and comfortable environment that is as homely as possible.
With the Full-scale, RGBWW, LED, circadian lighting at Esbjerg Psychiatric Hospital, light levels during the day are more than twice the specified standard, (minimum 450 lux on the eye of the general lighting) combined with illumination from wall fixtures, shelves, and so on. The light is simultaneously cool white with a color temperature of up to 5600 K in the late morning.
Patients, who suffer from anxiety, often sleep with the lights on. All the lighting fixtures in the patient areas are part of the circadian rhythm lighting, independently of where the lamps are located. Lamps can be switched on and off manually, but when at night, a patient turns on a bed lamp, the blue and green LEDs in the RGBWW LED lighting are eliminated, and so it has a significantly lower level and a different spectral distribution than during the day.
The project was completed in 2014 in coorporation with Arkitema Architects.
