The “LED professional Symposium“, or “LpS” for short, is an annual physical event in Austria that started in 2011. However, due to circumstances caused by the pandemic, it has been held digitally for the past two years. Light and lighting experts from over 30 countries from companies like Acuity Brands, Amerlux, ams OSRAM, Aspoeck, Bartenbach, BJB, Broadcom, Current, DeltaLIGHT, Etap Lighting, Fulham, Future Electronics, Gewiss, Ledvance, Legrand, LichtKunstLicht, LightingEurope, Louis Poulsen, Lund University, Nichia, Panasonic, Regent, Rensselaer Polytechnic Institute, RIDI, Samsung, SBB CFF FFS, Silanna, Schreder, Signify, SIMON, Tridonic, UL, Wago, Zumtobel participated to the 2022 event.

“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.

“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.

“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.

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.
