DOE Releases SSL Manufacturing R&D Roadmap

The U.S. Department of Energy has published the 2010 edition of the Solid-State Lighting (SSL) Manufacturing R&D Roadmap. Complementing the SSL R&D Multi-Year Program Plan (MYPP) that guides the Core and Product Development R&D programs, the Roadmap's primary goal is to guide the manufacturing R&D program and help direct funding solicitations for it. Manufacturing R&D is a part of DOE's SSL manufacturing initiative launched in 2009. The Roadmap also provides guidance for equipment and material suppliers, based on industry consensus on the expected evolution of SSL manufacturing – thereby reducing risk, improving quality, increasing yields, and lowering costs.
