As part of its analysis of public-private partnerships, the Academies convened leading academic researchers, government officials and policy makers, and representatives from large and small firms to explore the potential contributions, technical challenges, and opportunities for government - industry - university collaboration in the area of solid-state lighting. The workshop report devotes special attention to the potential for substantial social benefits - relating to the environment, energy consumption, and national security - that could arise with the widespread use of solid-state lighting technology. The workshop also focused on the technical and competitive hurdles currently faced in bringing solid-state lighting to market and the potential contributions of a well-conceived national consortium for solid-state lighting research.
