Qualified Bluetooth Mesh – Making Lighting Controls Future-Proof
LpR 69 Article, page 88: At Lightfair USA, Siegfried Luger met with Patrick Durand, Worldwide Technical Director at Future Lighting Solutions. One of Mr. Durand’s striking statements was: “Basically, what we need is to future-proof lighting control.” This was the first time that this important aspect was so clearly addressed by a representative of the industry. This led us to asking Mr. Durand to provide LED professional with a technical article to clarify the current situation, explain the technical background that led him to making that statement and to give an idea of which requirements a controls solution must fulfill to be truly future-proof.

Tech-Talks BREGENZ - Rico Kramer, Inventor, Founder & CEO, esave ag
In recent years there has been a strong focus on safe communication and controls in the lighting industry. The success story of esave ag, however, started much earlier, when Rico Kramer, the founder and CEO of esave, travelled to Taiwan due to his dissatisfaction with the quality of early LED replacement bulbs. What the former Apple employee learned there led to the development of the esave concept and its technology. In the interview he talks about his intentions, the beginning of esave, wireless technologies in general, system security, commissioning, system incompatibilities, markets and their peculiarities.

A Manufacturing Revolution for the LED Lighting Industry
LpR 67 Article, page 76: Western business investments in local manufacturing facilities have been declining since the 1980s due to partnering with contract manufacturers in Asia. But with increasing and hidden costs in Asia, companies are now seeking to bring manufacturing back home. A recent innovation, microfactories, could be the solution. Paavo Käkelä, Chairman and VP at EID Tech in Finland, presents the microfactory called Ant PlantTM. He explains this new, flexible manufacturing concept, shows how it works and how it is set up, and analyzes the benefits of local, automated production of LED lighting products as an alternative to contract manufacturing in Asia.

Fraunhofer IIS IoT-Bus: The Secure Communication Bus - Not Just for Lighting
The Fraunhofer Institute for Integrated Circuits IIS is developing the IoT-Bus with IPv6 support and integrated security concept. It is a communication bus based on EIA/RS-485 and the IEEE 802.15.4 standard, which enables a secure and reliable data transmission of measured values and control commands and connectivity to the Internet of Things. The IoT-Bus forms a cross-media communication protocol and unites the two worlds of WPAN and fieldbuses without complex protocol conversion. The novel technology IoT-Bus is developed as part of the SEEDs project.

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.

A Standardized Open Platform Is Key to the Future of Smart Lighting System Design
The LED industry’s pace of evolution is more prevalent now than it has ever been. The shift from traditional
standalone LED bulb lighting to fully connected digital LED systems is upon us and is transforming the
industry for the better. For years, LED manufacturers have focused on driving cost down rather than
focusing on improving quality, but with the advent of connected lighting, smart lighting and human-centric
lighting, the focus has shifted back onto quality. Dr. Kyeongik Min, Principal Engineer in the LED business
team at Samsung Electronics, explores how the LED industry can accelerate the transition from
standalone lighting to fully connected lighting through a deeper understanding of current market trends.
