Challenges when Designing LED-Based Illumination Systems in Medical Applications and Diagnostics
LEDs have become indispensable in medical technology and dentistry. But the requirements placed on these lighting products are very high: Minimized size, high, application specific color rendering index, efficient temperature management, usability and excellent disinfection opportunities are all extremely important. Prof. Paola Belloni from the Steinbeis Transfer Center Illumination Optics and Lighting Engineering and Furtwangen University, and Alexander Gärtner from the Faculty of Mechanical and Medical Engineering of the Furtwangen University discuss the requirements for different applications such as endoscopy, surgeries, dental devices, and photodynamic therapy. Further topics are the development of a self-disinfecting operation interface with edge-lit UV-A LEDs, and a new optimization approach, taking into account the reflection and absorption properties of human tissues.

GaN-on-Silicon Substrate Patent Investigation - Knowmade & Yole See More Players on the Playground
GaN-on-Si technology appeared naturally as an alternative to GaN-on-Sapphire—the main stream technology for LED applications. Today, despite potential cost benefits, the mass adoption of GaN-on-Si technology for LED applications remains unclear. Most major LED makers have a patenting activity related to GaN-on-Si technology, but so far, few have made it the core of their strategy and technology roadmap. Contrary to the LED industry, we expect GaN-on-Si to be widely adopted by Power Electronics and RF applications because of its lower cost and CMOS compatibility. Read more »

Tech-Talks BREGENZ - Prof. Christian Cajochen, Univ. Basel, Head of Center of Chronobiology
Human Centric Lighting has become a catchphrase used by industry and the press. But the press has also started reporting that research emphasizes the danger of LED lighting in connection to our health and has coined the term “Blue Light Hazard”. These claims have caused confusion amongst end users and throughout the lighting community. Prof. Christian Cajochen, Head of the Centre for Chronobiology at the University of Basel - an expert on this topic - held a lecture at the LpS 2016 entitled “Light Beyond Vision”. Afterwards, LED professional seized the opportunity to talk to him personally and get some in-depth information about the risks and benefits of LED lighting. Read more »

LED Lamps Recycling Technology for a Circular Economy
While having a long propagated lifetime, LED lighting products, especially lamps, have a foreseeable end of life. And since they contain many valuable elements they practically beg to be recycled. However, like other highly integrated electronics products recycling is not a simple task. Andrea Gassmann, Jörg Zimmermann, Roland Gauß, Rudolf Stauber and Oliver Gutfleisch from the Fraunhofer Project Group Materials Recycling and Resource Strategies IWKS and the Technische Universität Darmstadt Institute for Materials Science respectively, present and discuss a method that could open the way to successful recirculation of precious components and materials.

Human-Centric Lighting: Sensor Technology for Full- Spectrum Lighting Solutions by ams
While not necessarily common knowledge, research is rapidly validating the common-sense understanding that human beings are “tuned” to the natural lighting cycles of the sun, and can be equally “de-tuned”, to the detriment of both health and productivity, by artificial light sources that operate contrary to these natural flows. Sajol Ghoshal, Director of Sensor Driven Lighting at the Opto Sensor and Lighting BU at ams, discusses the available approaches for full-spectrum solutions, and potential humancentric benefits, of fully integrated intelligent ambient/color light sensor and driver technology.
