Holmes Auditorium, Harder Hall

Dr. John Edmond
Co-Founder and Director of Advanced Optoelectronics
Cree, Inc.
Cree, North Carolina, USA

Dr. John EdmondDr. John Edmond graduated summa cum laude from Alfred University in 1983 with a BS in ceramic engineering. He was awarded the Office of Naval Research Fellowship for graduate school studies. He earned his PhD in Materials Science at NC State University in 1987 and upon graduation co-founded Cree, Inc. Since its founding, Dr. Edmond has worked on the development and production of blue, green and white LEDs.

In 2007, Edmond earned a place on Business 2.0s ‘50 Who Matter Now’ list. The distinction placed him alongside business celebrities such as the late Steve Jobs, founder and CEO of Apple, and the chiefs of Amazon, Cisco and Google. In 2012, he received the Distinguished Engineering Alumnus Award from NC State. In 2014, he received the Charlotte Business Journal Energy Leadership Award.

Today, his research is focused on on advancing the performance of LEDs to enable the next generation of high efficiency solid state lighting solutions. He has 156 issued and 13 pending patents in the US, with an additional 257 issued and 29 pending foreign patents in these fields of research. Dr. Edmond is a member of the AU Board of Trustees.


Reinventing Lighting
With the advances in LED efficiency over the last several years, solid state lighting in the marketplace has grown significantly. This includes outdoor full color displays, street and parking deck lighting, indoor lighting and hand held devices. In each application, there is an optimization between the LED chips, the components they are encapsulated into and the lighting systems made from these components.

In this presentation, several aspects of the lighting system will be considered. This will include chip design, the chip interaction with phosphors and their incorporation in various component types. System optimization with respect to electrical and optical characteristics such as voltage, color temperature, color rendering index and luminous efficiency will also be discussed. Other key aspects of what matters for the growth of the solid state lighting market going forward (lm/W/$) will be presented as well.
