Georges Zissis, PhD, SMIEEE, President IEEE Industrial Application Society for the period 2019-20. Born in Athens in 1964, has graduated in 1986 from Physics department of University of Crete in general physics. He got his MSc and PhD in Plasma Science in 1987 and 1990 from Toulouse 3 University (France). He is today full Professor in Toulouse 3 University (France). His primary area of work is in the field of Light Sources Science and Technology. He is especially interested in the physics of electrical discharges used as light sources; system and metrology issues for solid-state lighting systems; normalization and quality issues for light sources; impact of lighting to energy, environment, quality of life, health and security; interaction between light source and associated power supply; illumination and lighting. He is director of “Light & Matter” research group of LAPLACE that enrols 20 researchers. He won in December 2006 the 1st Award of the International Electrotechnical Committee (IEC) Centenary Challenge for his work on normalization for urban lighting systems (in conjunction with IEEE, IET and the Observer). In 2009, he won the Energy Globe Award for France and he got the Fresnel Medal from the French Illuminating Engineering Society. In 2011 has been awarded the title of Professor Honoris Causa of Saint Petersburg State University (Russian Federation) and he is President of the Power Electronics, Electronics, Optoelectronics and System section of the French National Council of Universities for the period 2014-19.

Keynote Speech: Light Beyond Lighting, Frontiers in Lighting Technologies: The Human-centric Intelligent Lighting Challenge

Abstract: Since the human race emerged it has been known that fire and heated objects emit light that can be used for lighting purposes; artificial lighting has been discovered. Since of 19th-century end, artificial lighting has been the subject of a continuous and fascinating evolution; 20th century scientists and development engineers worldwide created such a wide range of lighting solutions for every lighting application.

Today, the importance and application of these “legacy” lighting technologies is decreasing. During the last decade, Solid-State Lighting (LEDs, O-LEDs, solid-state lasers) challenges conventional technologies. In particular, LED has turned into a game changer beating the conventional technologies in all aspects. It is therefore anticipated that in short term, all of electric lighting will be based on SSLs. Should SSL revolution proceed to the projected conclusion, replacing all legacy technologies, there will be a further major change in the lighting market.

Artificial light production absorbs 15% of the world’s electricity annual production. Therefore, past century’s research and development focused on single energy efficacy enhancement. Consequently, we knowingly were not serving society as effectively as we could. Industry has coined a new term “human-centric lighting” to draw renewed attention to its primary effort to be successful in meeting society’s needs. Furthermore, we are witnessing a transition from the conventional “analogue” lighting technologies to “digital” lighting. Intelligent lighting will become the backbone for smart homes and smart cities. This way, lighting will become the heart of the “Internet of Things”.
