Celebration 15-5-50 & Exclusive Zhaga Papers The numbers 15-5-50 stand for the three reasons we are celebrating this year; namely the International Year of Light 2015, the 5th anniversary of the LpS event in Bregenz and the 50 th issue of the LED professional Review (LpR).

After celebrating the publication of LpR issue #50 in August, we are now looking forward to the upcoming LpS 2015 event which will take place in Bregenz on September 22-24. The focus of the 5th LpS is on the trends and technologies for future lighting solutions.

This year the program concentrates on the building blocks for smart lighting designs.

A special Design-meets-Technology Day on September 22nd will bring architects, lighting designers and lighting planners together with experts from academia and industry. Closing the gap for understanding new technologies between these different groups could be essential for further progress because innovations are mainly driven from the directions of applications and technologies.

The LpS 2015 will open with the keynotes from Professor Zary Segall from the Royal Institute of Technology in Sweden, Rogier van der Heide, Design and Marketing Officer at Zumtobel Group in Austria and Jy Bhardwaj, CTO at Lumileds in the USA. About 60 presentations are grouped into the following sessions: Light Quality, Connectivity & Security, Reliability & Lifetime, Standardization, Light Sources, Smart Controls & Drivers, Thermal Management and Optics. There will be 7 workshops which are meant to augment comprehension in the fields of Light Measurement, Optics, Thermal Management, OLEDs, Smart Controls, Light Mixing and Automotive Lighting. You’ll find the complete program as part of this issue.

The combination of the numbers 15-5-50 also affects our view of the synergies between international lighting collaborations, lighting events and lighting publications.

This view was corroborated recently when we announced our long-term strategic partnership with the esteemed Messe Muenchen, organizer of the electronica and productronica, to further strengthen and force Solid-State-Lighting topics on an international scale. I would like to take this opportunity to thank Managing Director Mr. Senger and Dr. Lechner and his team for establishing this partnership.

As an exclusive highlight, this issue of the LpR includes the latest technical articles from The Zhaga Consortium including the latest information and updates on COB modules, Driver and Module Interfaces, Thermal Interfaces and LES Considerations.

Thank you to Musa Unmehopa and Tim Whittaker for this rewarding collaboration!

Further in this issue you’ll find articles about research in phosphor materials for COB modules, photometric considerations of light measurements, graphene based LED technology, chip-array technology for SMD packages, thermal management considerations of PCB designs and noteworthy facts about light-pollution.

Have a great read.

Yours Sincerely,

Siegfried Luger CEO, Luger Research e.U. Publisher, LED professional Event Director, LpS 2015
