Human centric lighting is intended to promote a person’s well-being, mood and health. It can improve concentration, safety and efficiency in workplaces or educational environments. It can support healing processes and prevention of chronic diseases among persons with irregular daily routines or in elder care. For the first time, a joint study by LightingEurope, the German Electrical and Electronic Manufacturers’ Association (ZVEI), and the global management consulting firm A.T. Kearney shows that human centric lighting can become a multi-billion-euro business, covering around 7% of the general lighting market in Europe.
