High power light emitting diodes (LEDs) have begun to differentiate themselves from their more common cousins the indicator LED. Today these LEDs are designed to generate from 10's to over 100 lumens per LED with efficiencies that surpass incandescent and halogen bulbs even in white. This talk will begin by looking at the motivation for development of high power LEDs as well as some of the technical developments that make these LEDs possible. Challenges that lay ahead for development of a true "solid state lamp" will be discussed. I will conclude by showing results from the world's first 100-plus lumen white LED (now in production at Lumileds), the solid state equivalent of Thomas Edison's 20W incandescent light bulb but approximately one century later.
As an example, at right is the Luxeon Ring fixture by Philips Lighting, casting white light on an end table.
- Speaker Biography
Paul S. Martin, a San Jose native, received his B.S. degree in physics from Cal Poly San Luis Obispo in 1985 and his Ph.D. degree in physics from MIT in 1996. He spent a year between 1989 and 1990 with the KDD Meguro Research Laboratories, Tokyo, Japan as part of the MIT-Japan internship program. In 1996 he joined Hewlett-Packard's Optoelectronics Division Research and Development Group in San Jose, CA. Since joining HP, Paul as remained in the same building while his company has changed around him -- from HP to Agilent and now to Lumileds Lighting. Paul is currently the manager of the product development group for Lumileds Lighting.
