Based on constantly evolving research, we recognize the importance of the right quality of light for our health, well-being and productivity. For a well thought-out, contemporary interior, we need a well designed, innovative lighting concept in our own spaces that takes the latest psychological and physiological findings into account. Together with the doctor and chronobiologist Dr. Dieter Kunz, a leading researcher for sleep- and chronomedicine in Berlin and the designers of "LICHT KUNST LICHT“, Collignon developed a lighting concept that changes dynamically throughout the day on the basis of the circadian rhythm and thus adapts to biological needs. "Such lighting systems actively contribute to maintaining and increasing the health, well-being and performance of employees," says Dr. Dieter Kunz. Only about 15 years ago, it was discovered that there is a photoreceptor on the retina, which tells our internal clock the information "day" or "night" and the length of the day. This receptor is essentially responsive to blue light. "This means that we strengthen our health when we use dynamic light, with a high percentage of blue during the day and a warmer light color towards the night," explains the physician. In the evening, this creates a warm, intimate space of light at the workplace. The lighting mood in our office appeals to the archaic, millennia-old human programming: During the day it resembles being under the open sky and we feel fresh and energetic; In the evening, we have a similar feeling as if we were sitting around a fire in our shelter.
