Update DOE solid-state lighting R & D program 2020 years effect over 200lm/W

The U.S. Department of energy released the March 2010 edition of solid-state lighting (SSL) years of research and development project (MYPP).

MYPP describes the next few years the U.S. Department of energy plans to implement the SSL plan. In addition, the paper also reviews the status of solid state lighting (SSL) technology, as well as the development trend of LED and OLED, and the United States Department of energy SSL R & D project portfolio is outlined.

The latest research and development plan to collect and reference to the data provided by many experts, including experts and scholars in various fields of the industry, as well as equipment and lighting manufacturers, etc..

The latest progress in research and development of DOE and the previously published research program, in technology research and development project there is some deviation, so the update is to adjust the future development plans to build on the progress.

The program seeks to identify areas of financial support in the short term, and clear the scope and content of the work carried out.

SSL Jim is responsible for the Brodrick project, said that at present, although the effect of warm white LED is much lower than the cold white LED products, but the gap can be reduced. Eventually, after the package warm white and cold white LED light effect is expected to close to 200lm/W. (http://www.ledsmagazine.com/news/7/4/2)

DOE solid state lighting research and development projects for many years the latest indicators:
