Dr. Deborah Chung to Speak on Materials for LED Heat Dissipation at coolingZONE LED 2012 in Berlin

April 25, 2012 - PRLog -- Dr. Deborah Chung, a National Grid Endowed Chair Professor, Director of the Composite Materials Research Laboratory and Professor of Mechanical and Aerospace Engineering at the State University of New York (SUNY) at Buffalo, will speak on Materials for LED Heat Dissipation, at coolingZONE LED 2012, Berlin, Germany, May 29-June 1, 2012.

Overheating is one of the biggest problems in the LED lighting industry. High-power (high-brightness, e.g., 100 lumens per Watt) LEDs are aimed at general illumination (i.e., replacing incandescent lamps), automotive head lamps and other applications. Unfortunately, most of the electrical power input to an LED is converted to heat, so operation of LEDs at high power results in a high heat flux (e.g., more than 80 W/cm2).  The rise in temperature causes decrease in the light output power efficiency.

Not only does the rise in temperature reduce its lifetime, the heat causes shift in the wavelength of the LED, thus causing color shift. For the above reasons, a low operation temperature is greatly needed for LEDs.  The heat problem is made even more serious by the fact that the market requires LEDs to have high power and packaging density.  Many applications demand LEDs to operate at full power or even beyond the full power in order to attain the required brightness.  Dr. Chung’s talk will cover how to address these issues through the right materials choice

Dr. Chung is National Grid Endowed Chair Professor, Director of the Composite Materials Research Laboratory and Professor of Mechanical and Aerospace Engineering in SUNY/Buffalo. She holds a Ph.D. degree in Materials Science and an S.M. degree from M.I.T., and an M.S. degree in Engineering Science and a B.S. degree in Engineering and Applied Science from California Institute of Technology. She has authored or coauthored almost 500 published papers, authored five encyclopedia articles, and has edited two books, which include Materials for Electronic Packaging (Butterworth, 1995). She is the inventor of 15 patents and has given over 200 invited lectures. Her research has covered many materials, including lightweight structural materials, construction materials, smart materials, electromagnetic materials, thermal management materials, electronic packaging materials, adsorption materials, battery electrode materials and solar cell materials.

coolingZONE LED 2012 is being held May 29th through June 1, 2012, at the Hilton Berlin, Berlin, Germany.  CoolingZONE LED 2012 is the only LED event dedicated to the thermal management of LED Lighting.

This event will feature experts in the field of LED thermal management to share their latest developments, research, and practical approaches to LED cooling. Engineers who attend cooilngZONE LED events will learn about today’s LED cooling challenges, where the solutions will be found, and who can help them with effective products and services to manage today’s thermal challenges.

coolingZONE LED 2012 agenda includes a full day of technical presentations from leading experts in industry and academia. Short technical sessions will be provided by corporations who are advancing the thermal management community with innovative and practical thermal solutions. Multiple short courses are offered as an integral part of the program for in depth training.

Engineers, engineering managers and executives, chief technical officers, project managers, professors, students and others who want insight into the thermal design issues related to LED Lighting that affect product performance and the latest advancements in solving these critical thermal challenges.
