At the 5th LED professional Symposium +Expo (LpS 2015), experts from the lighting industry came together in Bregenz to analyse trends and technologies for future SSL solutions. More than 100 well-known companies exhibited this year, including the world’s top LED manufacturers Nichia, Cree, Everlight, Lumileds, Osram, Samsung and Seoul Semiconductor. A total of eighteen products have been launched and the best scientific paper has been honoured with the LED professional Scientific Award.

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, Mr. Rogier Van der Heide, Chief Design and Marketing Officer, Zumtobel Group, and Mr. 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.

Technology Focus

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, standardisation, light measurement, production and lighting systems. While Dr. Doxsee talked about LED light for visual merchandising, Prof. Zissis from the Toulouse 3 University in France gave a talk on Quality of Lamps and Associated Health Issues and SSL expert Alexander Wilm from Osram Opto Semiconductor gave a report on a reality lifetime check of LED lighting systems.

One highlight of the exhibition is the colour portfolio from Lumileds, where all physical parameters of the LEDs out of the series are homogenised so that one lens fits all colours despite different LED technologies. Marula LED introduced their 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 BMW i8 with laser headlights.

Design meets Technology

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 honoured 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.
