LpS Digital Summit 2022 – Keynotes, Panel Discussion, Awards

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 registered for this year’s event.

The keynotes addressed very current lighting topics and highlighted the latest trends:

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 holds degrees in Economics and European Law.

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.

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.

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.

This year, the LpS Digital Awards were presented in four categories: Products, Sustainability, Scientific Paper and Achievement Awards, and the winners are:

• Product Award: Nichia’s Dynasolis
• Product Award: Samsung’s LH502D
• Product Award: LEDiL’s YASMEEN
• Product Award: ams OSRAM’s DALI PRO 2 IoT
• Product Award: EnOcean’s STM550
• Sustainability Award: TE Connectivity’s LUMAWISE Motion Sensor
• Scientific Best Paper Award: Dr. Eric VIREY from Yole Group
• Achievement Award: Jan DENNEMAN from the GoodLightGroup

Statement of the Jury: “The connection between health and light is increasingly recognized in greater depth and will become even more significant in the future. The Dynasolis innovation is an entirely new LED tuning solution that regulates circadian rhythms by adjusting melanopic illuminance and color temperature while maintaining high CRI and efficacy. It is the combination of the energizing azure (sky blue) and a peaceful, calming warm white hue focusing on the non-visual element that truly addresses HCL. Applications range from medical, office, education and even residentials.”

Statement of the Jury: “In Europe, more than 50% of outdoor lighting systems are outdated. There are safety, security and consumption issues. The LH502D shows high performance in multiple core reliability tests with an increased lifetime. The new 3-layer anti-sulfurization ceramic coating technology with a 5050 LED package offers improved performance with reduced costs to support investments for new and retrofit installations – especially for harsh environments such as streets- and tunnel lighting.”

Statement of the Jury: “YASMEEN zoom is a zoom optic family that enables new lighting possibilities thanks to its flexibility and adaptability. YASMEEN zoom optics are unique, as they have been designed with no axially moving parts. Luminaires can be made smaller, are easier to design, and fit into existing track light concepts. YASMEEN zoom optics can be used for compact retail lighting luminaire designs that demand the flexibility of easily adjusting zoom optics in a single luminaire. YASMEEN zoom optics also support sustainability: there’s no need to replace and possibly dispose of luminaires.”

Statement of the Jury:  “DALI PRO 2 IoT is a lighting control technology with an integrated IoT gateway and open REST/ MQTT API provide access to cloud applications, thus enabling IoT use cases. Luminaire information, energy consumption and maintenance data can be pushed to the cloud. The Energy Monitoring and Maintenance Assistant (EM/MA) cloud service enables facility managers to monitor their lighting installations, gain insight into individual energy consumption areas, identify maintenance needs and making system updates remotely. This enables energy and cost and investment (replacements) savings.” 

Statement of the Jury: “The STM 550 multisensor family combines temperature, humidity, lighting, acceleration, and magnetic contact sensors in a small case. The multisensor is for the EnOcean wireless standard and for Bluetooth® systems and can be used for IoT and digitized building applications. An integrated solar cell supplies the sensor itself with energy for uninterrupted operation over several days with little or no light. STM 550 operates completely maintenance-free. It can also be integrated into a wide variety of assets and therefore can be used where the data is needed: on walls, ceilings, windows, doors, furniture, active devices, and objects. The multisensor has an integrated NFC interface for configuration and commissioning.”

Statement of the Jury: “LUMAWISE is a new motion sensor designed to bring sustainability and efficiency to street lighting architecture. With detection zones up to 30x6 meters and strong infrared sensing capabilities, LUMAWISE Motion Sensor can light the way, even in harsh environments. Enabling energy savings from dimming or even turning off a luminaire while still being able to react to motion and bring a luminaire to full brightness for safety and security reasons. LUMAWISE Motion will fit into the Zhaga-D4i ecosystem, which is the new standard for smart cities. It works as a standalone control device or in combination with Zhaga-D4i photocell or communication node for greater levels of controls. The sensor is a pluggable device, with the standard Zhaga book 18 interface for an easy upgrade.”

“Will MicroLEDs Revolutionize the Display Industry?”, LpR94, Nov/Dec 2022, p46-51.
Statement of the Jury:  “The lecture gives a profound overview of technology at the edge of commercial implementation. It describes various aspects, both commercial and technological. It shows hurdles and chances and compares them with competing technologies (LCD, OLED).”

Statement of the Jury: “Jan Denneman has dedicated over 40 years of his professional career to developing and promoting the lighting sector. He has initiated several international consortia, like the Global Lighting Association, Zhaga, the Connected Lighting Alliance, and LightingEurope. He also founded the GoodLightGroup, where he serves as  Chairman. He is passionate about light and health, and rethinking lighting again.”
