SoC Technologies in Lighting - Today’s Landscape and Tomorrow's Practices
A system-on-chip (SoC) quite suddenly became an important component in the lighting industry,
fueling IoT innovation and opening new opportunities, while at the same time bringing disruption and
new challenges. With rapid advancements in wireless communication, the impact of connected
technologies on the lighting business will only keep increasing. This means deeper integration with
SoCs and more attention from silicon vendors as they start competing for market share in this
promising segment. But what is the current state of SoC design from the lighting perspective?
Are chipmakers keeping up with the growing expectations for wireless lighting control solutions that
are mature and truly reliable? When developing its complete Bluetooth software stack for professional
lighting, Silvair worked with a number of different SoCs. Therefore, Piotr Winiarczyk, Wireless Solution
Architect, and Szymon Rzadkosz might have found the answers to these questions.

LED Driver Miniaturization - Opening New Opportunities for Solid State Lighting
While LEDs have significantly improved over the past decade, driver technologies have not kept pace and
are, in some respects, the limiting factors for new applications. Size is a particular issue. Dramatically
increasing the switching frequency helps to reduce size but often causes other issues or is costly. Mickey
Madsen, CEO of Nordic Power Converters, explains how his company has overcome the hurdles and
made it feasible by designing very high frequency LED drivers.

LED-Retrofit Based on AlGaN/GaN-on-Si Field- Effect Transistor Drivers
Efficient driver technologies for LED systems are still a relevant topic. Several new approaches are
proposed and new technologies are under development. Andreas Zibold, PhD student at the
Fraunhofer Institute for Applied Solid State Physics IAF, and his co-authors, M. Kunzer, R. Reiner,
B. Weiß, P. Waltereit, R. Quay, J. Wagner, and O. Ambacher demonstrate the suitability of AlGaN/GaNon-
Si field effect transistors (FETs) for their use in LED drivers. The transistors are tested in an isolated
buck converter and an efficiency of 86% is measured for the full converter circuit. The driver circuit is
combined with an LED module based on a laser-structured Aluminum Nitride (AlN) ceramic board onto
which 21 high power white-emitting LED chips are mounted. This combination resulted in an LEDRetrofit
lamp with a total light output of 2676 lm at an efficacy level of 119 lm/W. The results compare
favorably to state-of-the-art commercial solutions.
