LpS 2015 – Experts Analyze Trends and Technologies for Future Lighting Solutions

The LpS 2015 started on September 22nd with an opening speech by Joe Niemela, Global Coordinator of IYL 2015 and continued with three keynotes by Professor Zary Segall – Endowed Chair Professor at The Royal Institute of Technology (KTH) in Stockholm, Rogier Van der Heide – Chief Design and Marketing Officer, Zumtobel Group and Jy Bhardwaj – Senior Vice President R&D, Lumileds. After the keynotes, which outlined the latest trends, technologies and applications, the lecture series with sixty presentations and seven workshops commenced. 

In the course of the opening, the scientific award was given to Dr. Wolfgang Nemitz for his paper on an interactive optical and thermal simulation method for proper simulations of phosphor covered LEDs.

The technical lectures at the LpS 2015 cover the whole of the LED light value chain, from electronic components to complete lighting system. They focus on light sources, smart controls and drivers, optics, light quality, light mixing, connectivity, security, reliability and lifetime, standardization, light measurement, production and lighting systems. 

The technological focus of the event can also be seen at the exhibition, where over one hundred well-known companies, including the world’s top LED manufacturers Nichia, Cree, Everlight, Lumileds, Osram, Samsung and Seoul Semiconductor showcased their latest products and services. There were also a total of eighteen product launches made here. A highlight of the exhibition is the color portfolio from Lumileds, where all physical parameters of the LEDs out of the series are homogenized so that one lens fits all colors despite different LED technologies. Marula LED introduced their new MA 1077 Driver IC, which ensures transformer compatibility of low voltage LED lamps and Escatec showcased a new heat spreader solution for LEDs which are soldered onto a copper substrate that is up to ten times more effective at dissipating heat than current solutions. Another highlight of the exhibition is the new BMW i8 with laser headlights. 

In addition to the technical event program a “Design meets Technology Day” took place on the first day of the event that enabled a collaboration and dialogue between engineers and technicians as well as lighting designers, planners and architects. Architects and lighting planners were taken through the exhibition in small groups. The tour included demonstrations and product presentations across the lighting value chain. Furthermore, sixteen students showcased their lighting design prototypes. 

These prototypes are the result of a four-month long design contest, devised by the University of Applied Sciences in Munich and Seoul Semiconductor. The most interesting prototypes were honored as a part of the Design meets Technology Day. According to the jury it was extremely difficult to choose a winner, as all prototypes were so different in their designs and application. Finally they agreed not to award any of the projects but to highlight one prototype that was the most interesting from a technical point of view: a construction lamp from Lena Gillitzer. It wouldn’t be possible to build her lamp without the driverless Acrich technology invented by Seoul Semiconductor.
