The keynotes addressed very current lighting topics and highlighted the latest trends:
“Lighting Future – Challenges and Opportunities” by Ourania Georgoutsakou
Future lighting: the challenges are also the opportunities, if only we look at them in the right light. Europe’s lighting industry will continue to have to deal with the impact of a global pandemic, as well as a war on the European continent, now, and clear signs of changes to established geopolitical relations. Demand for energy savings, a strong EU policy push for sustainability, upcoming product restrictions and an accelerated renovation wave are all opportunities to install better lighting for people and the planet. While it’s not always easy to do so in times of change, as long as we remain true to what our industry is fundamentally about – making our surroundings beautiful, making them easy and safe to navigate – the future of lighting will be bright.
Ourania Georgoutsakou joined LightingEurope, the voice of the European Lighting Industry, as Secretary General in April 2017 with 15-years of experience advocating for membership associations. Ourania worked for five years as Director, Public Policy Europe for SEMI, the global trade association representing the manufacturing supply chain for the semiconductor and related industries. She liaised with SEMI member companies and EU decision-makers to create a balanced regulatory environment and to promote Europe’s global competitiveness. Previous to that, Ourania Senior Policy Coordinator at the Assembly of European Regions in Brussels and Strasbourg for ten years, where she worked directly with elected regional politicians to help shape and implement EU policies. During her career Ourania has worked on several issues, from the EU Lisbon Treaty to the EU services Directive, and from health and social policy to environmental rules and e-innovation. Ourania holds degrees in Economics and European Law.
“Outdoor Lighting: Saving Potentials with Latest LED Technologies” by Aleksandar Nastov
Aleksandar Nastov is Senior Manager at Samsung Semiconductor Europe, LED. He leads the introduction of products and the development of new business opportunities. Samsung LED entered into a large number of new application areas, especially with new and industry leading technologies.
“Melanopic Lighting Systems” by Dr. Rene Wegh
Light is the most powerful regulator of our circadian rhythm. The fact that we spend, on average, more than 90% of our time indoors in dim light conditions causes circadian misalignment, which in turn can cause sleep disorders and other negative health effects. To prevent this we should optimize indoor lighting, in particular, by providing melanopic light i.e. cyan-enhanced light during the day, as cyan light is most effective in stimulating the circadian rhythm. The melanopic light sources as proposed by Signify were presented, and trade-offs with, for example, CRI and luminous efficacy were discussed.
Dr. Rene Wegh is topic leader in the field of solid-state light sources at Signify, formerly Philips Lighting. In that role he is overviewing the field and driving innovations on SSL sources. He has a 15-year track record on development of spectral engineering innovations at Philips Lighting/Signify, ranging from various remote-phosphor platforms, in the early days, to high-CRI and Human Centric Lighting spectral solutions in recent years. He holds a Ph.D. in chemistry from Utrecht University on the topic of luminescence spectroscopy of lanthanide-based phosphor materials. He joined Philips in 1999, starting at the corporate Research lab where he worked on various topics, including color filters for LCDs and light-emitting electrochemical cells for lighting, before moving to Philips Lighting in 2006.
“Lighting Could be Much Smarter” by Professor Dr. Robert F. Karlicek, Jr.
An unrealized promise of LED lighting involves developing lighting control systems that always place the “right light where and when it is needed.” This talk explored how evolving spatially and spectrally tunable lighting systems can be combined with evolving sensing platforms, novel control methods, and machine learning to create autonomous lighting control methods that recognize how to “sculpt” lighting spectral and spatial distributions that dynamically and autonomously optimize illumination based on the control system’s ability to sense occupant location and activity. It was proposed, that with continued development of occupancy/light sensor systems with embedded intelligence, future lighting systems will be able to control themselves for improved energy savings and human wellness.
Dr. Robert F. Karlicek, Jr. is a professor of Electrical, Computer and Systems Engineering, and the Director of the Center for Lighting Enabled Systems & Applications (LESA) and co-Director of the Institute for Energy, Built Environment and Smart Systems (EBESS), both at Rensselaer Polytechnic Institute. Prior to RPI, he spent over 30 years in industrial research and R&D management positions related to optoelectronics, telecommunications and lighting system development with corporations including AT&T Bell Labs and General Electric. He obtained his Ph.D. in Physical Chemistry from the University of Pittsburgh and has over 56 peer reviewed technical papers and 48 U.S. patents.
The panel discussion with the keynote speakers highlighted the key trends in the lighting and illumination world and incorporated questions from the attendees.
The panelists developed essential summaries during the discussion:
• Lighting must be increasingly linked with the heating, ventilation and air conditioning world to achieve the best building solutions. The overriding goal is to achieve solutions that span all businesses. It’s a building approach rather than a lighting approach.
• Sustainability stays a crucial topic ranging from durability, recyclability, and modularization.
• Human Centric Lighting is becoming even more important.
• Intelligent systems require data for processing. Therefore, sensor technology, data acquisition and processing, and cloud systems are essential.
