Human-Centric Lighting – Quo Vadis
Lighting technology goes through a time of groundbreaking changes these days. The extensive application of the highly energy-efficient digital light source LED facilitates the generation of dynamic light spectra and luminous intensity distributions and the implementation of new lighting designs for special visual, biological and emotional needs. The integration of additional sensor-technologies (e.g. light- and motion-sensors, but also health-sensors and wearables) and the implementation of complex control algorithms will will support the transformation of current lighting systems into smart and adaptive lighting solutions that will instantaneously react to environmental alterations (e.g., time, weather) and individual desires (personalized lighting). But how can we exploit these new possibilities for the benefit of people? How can we start a sustainable social development (e.g. a “healthy” light) rather than merely creating technology driven gimmicks. The lighting industry observes current developments with regard to its emerging chances, and it appears as if euphoria is fading. The authors will present their positions based on own research and application experiences.
