Wide awake!


Light lifts spirits – something we notice when the sun comes out again ­after long, dark winter days. But light does more than “just” make ­people happy − light also impacts our health, as many biological processes depend on it. The importance of human centric lighting therefore continues to grow.

A biologist, a lighting designer and a product manager: Innovations are often created when people from different fields combine their knowledge – just like with human centric lighting (HCL), which Andreas Wojtysiak, Andreas ­Pickelein and Nicolai Heber are working on. The main question for them is this: how can we transform light into a sense of well-being or even use it to promote human health? “The answer to this question is an area of focus for OSRAM,” Andreas Wojtysiak says, explaining HCL’s importance. “It’s an especially exciting one too.”

“Light can produce any number of ­different effects. Our job is to ­find those that enable us to enhance the quality of life for people.” Andreas Wojtysiak, Biologist at Innovation

Only ten years ago, researchers proved what effect light has on the circadian rhythm of human beings. For OSRAM, their findings served as a decisive impetus. Light can have a stimulating or relaxing effect, depending on its intensity and color. The blue of the sky stimulates us and ultimately drives us to peak performance. In contrast, reddish light calms us down and sends the signal that it is time to sleep.

“That means having the right light in places like the office, health-care applications, schools or sports facilities can positively impact health and performance.” Nicolai Heber, Product Manager at Digital Systems

“We can simulate the effect of the natural progression between day and night with artificial light. That means having the right light in places like the office, health-care applications, schools or sports facilities can positively impact health and performance,” Nicolai Heber says with excitement. And that is not all. Other places, such as­ ­nursing homes, can also benefit from HCL. “With the right lighting, we can often improve the circadian rhythm in people suffering from dementia, helping them to maintain the distinction between day and night,” Andreas Pickelein explains.

Light also impacts regular day-­to-day work. For example, the company CBRE from the Netherlands has equipped its offices with an HCL solution from OSRAM. Doing so has resulted in employees who feel good and highly effective. “The range of possibilities for the targeted use of human centric lighting is huge,” Nicolai Heber says. “And we here at OSRAM are the experts on this. Our goal is to offer the right light for every need.” Andreas Wojtysiak adds, “We can help people in many areas of life by ­exploiting the ­fascinating possibilities of light. We have a major opportunity here.”

FINDINGS FROM A STUDY WITH HUMAN CENTRIC LIGHTING AT THE COMPANY CBRE

  • 76 % of the participants felt happier
  • 50 % of the participants felt healthier
  • 60 % of the participants felt more motivated
