Origins of White LED Technology with
March 26, 2015
Breakthroughs in the late 1980s and early 1990s in Japan, including those by Nobel-Prize-Winner Shuji Nakamura, now professor at the University of California Santa Barbara, ushered in a first era of light-emitting diode (LED) based white lighting that has revolutionized industries including flat-panel displays and, more recently, general lighting applications. These advances stood on the shoulders of previous work of almost thirty years in the development of red-emitting LEDs, with ties back to the invention of the transistor at AT&T Bell Labs in 1948. Just as the transistor replaced the vacuum tube, LEDs are positioned to replace conventional lighting technologies in many, if not all, applications. In order to realize this vision, Prof. Nakamura founded Soraa which has developed GaN-on-GaN technology to build upon his previous breakthroughs and to open up the pathway to the highest light quality and (eventually) lowest-cost approach to energy saving lighting technology. In this talk, Michael will summarize the history of LED development from the beginning up to GaN-on-GaN today.
Aurelien David is Senior Principal Scientist at Soraa, Inc. He has been involved in research on LED lighting for more than twelve years. His fields of expertise include: semiconductor physics; various aspects of LED efficiency; and color and vision science.
In 2006, he graduated with a PhD in Applied Physics from Ecole Polytechnique (France) and the University of California at Santa Barbara – where he worked with the research team spearheaded by Nobel laureate Shuji Nakamura. From 2006 to 2010 he worked at the Advanced Laboratories of Philips Lumileds on the optical and material properties of LEDs. In 2010 he joined Soraa to research the application of bulk GaN technology to LEDs.
His worked led to several demonstrations of ultra-high performance LED devices, including the record-high wall-plug efficiency LEDs recently demonstrated by Soraa; as well as to advances in color science which drive Soraa’s Quality of Light roadmap. He is the author of 35 international journal publications and 20 patents in the field of solid-state lighting. He is currently a member of the IES Task Force on Color Quality Metrics, a member of CIE TC1-90 (new Color Fidelity Index), and the chair of the IES Whiteness group.

Lumen West 2015, Inspired by Downton Abbey
Dear Lighting Design Community Member,
You are cordially invited to the Annual Lumen West Awards and Gala Event this June 20th, at the Avalon in Hollywood, California, to join in an evening of lighting, laughter, and all around gaiety. This year, we are honoring all those in the lighting industry who have worked together to create dazzling environments and interior spaces. The pleasure of your company is highly petitioned, as we cannot properly celebrate the marvel of our Lighting Community without you there.
Formal raiment and attire is required. Food and libations will be provided throughout the evening.
IESLA and the Crawley Family
