April 26, 2012…The U.S. Department of Energy published the April 2012 version of the Solid-State Lighting R&D Multi-Year Program Plan (MYPP). The report provides a description of the activities the Department plans to undertake over the next several years to implement its SSL mission, and informs the development of annual SSL R&D funding opportunities.
The MYPP reviews SSL technology status and trends for both LEDs and organic LEDs (OLEDs) and provides an overview of the current DOE SSL R&D project portfolio. The DOE made significant updates to the Technology Research and Development Plan including: revising efficiency projections, priorities, task descriptions, and metrics to align DOE targets with progress made to date and industry trends.
The DOE expanded projections for efficacy to include estimates of likely trends and limits for both phosphor-converted LEDs and color-mixed LEDs. The pc-LED discussion was reportedly updated to consider optimization of phosphors, one of the R&D directions. Additional discussions of hybrid solutions, the effects of low or high current drive, and other design variables were added. The DOE notes that the studies of cost and price trends were also updated. The proposed R&D priorities were explored in?two sets of roundtables?held in late 2011 as well as in breakout sessions held during the?2012 SSL R&D Workshop?in Atlanta.
According to the R&D plan’s preface, which is signed by James R. Brodick,?“This year’s update highlights continuing progress on more energy efficient lighting, with especially promising advances in luminaire products that are reliable, useful, and cost effective. Most of the rapidly growing market is for LED products, but OLEDs have made significant advances as well, with a number of new (albeit expensive) products now available on the market.”
The DOE indicated that it will continue to update the MYPP on an annual basis, with input from industry partners and workshop attendees, to incorporate new analysis, progress, and new research priorities as science evolves.

The end of the plan’s preface noted,?“Advances notwithstanding, the report also highlights remaining opportunities for further improvements. As in the past, DOE expects to issue competitive solicitations?the Core Technology Solicitation and the Product Development Solicitation?based on this plan, and closely focused on your consensus as to the most important priorities in the near term.”
