| GRAND CHALLENGE LDRD PROJECT |
To accelerate the development of the science and technology underlying Solid State Lighting, Sandia initiated, in October 2000, a multi-year Grand Challenge Laboratory Directed Research and Development (GCLDRD) project, " A Revolution in Lighting -- Building the Science and Technology Base for Ultra-Efficient Solid-State Lighting." This project is considered one of Sandia’s most successful GCLDRDs.
One way in which the SSL GCLDRD was different from others was that it coincided with a larger effort by the SSL community - primarily industrial companies investing in SSL, but also universities, trade organizations, and other Department of Energy (DOE) national laboratories - to support a national initiative in SSL R&D. Sandia was a major player in publicizing the tremendous energy savings potential of SSL, and in helping to develop, unify, and support community consensus for such an initiative. Hence, our activities in this area were substantial: white papers; SSL technology workshops and roadmaps; support for the Optoelectronics Industry Development Association (OIDA), DOE and Senator Bingaman&'s office; extensive public relations and media activities; and a worldwide SSL community website.
Many science and technology advances and breakthroughs were also enabled under this GCLDRD, resulting in: 55 publications; 124 presentations; 10 book chapters and reports; 5 U.S.patent applications including 1 already issued; and 14 patent disclosures not yet applied for. Twenty-six invited talks were given, at prestigious venues such as the American Physical Society Meeting, the Materials Research Society Meeting, the AVS International Symposium, and the Electrochemical Society Meeting. These advances spanned five technical task areas, listed here along with their coordinators:
1. Fundamental Materials Physics ( Carl Seager )
2. III-Nitride Growth Chemistry and Substrate Physics ( Mike Coltrin )
3. III-Nitride MOCVD Reactor Design and In-Situ Monitoring ( Bill Breiland )
4. Advanced Light-Emitting Devices ( Art Fischer )
5. Phosphors and Encapsulants ( Lauren Rohwer )
The management team consisted of: Jerry Simmons (project manager), James Gee, (principal investigator), Jeff Tsao (strategic planning), and Bob Biefeld (department manager).
The external advisory committee included the following members: Arpad Bergh (OIDA), Charles Becker (GE), George Craford (LumiLeds), Jeff Nelson (Uniroyal Optoelectronics), Russ Dupuis (U Texas), Jim Speck (UC Santa Barbara), Arto Nurmikko (Brown U), Ed Petrow (DOE), Jim Brodrick (DOE), John Carrano (DARPA), Bob Karlicek (Gelcore), John Zolper (DARPA), and Steve Johnson (LBNL).
This project was completed in September 2003; the final report is titled
