The U.S. Department of Energy announced nine research and development projects that will receive funding to support solid-state lighting (SSL) core technology research and product development. The projects, the department said, will help accelerate the development of high-quality light-emitting diode (LED) and organic light-emitting diode (OLED) products. This is the department’s ninth round of investments in SSL core technology R&D. In total, the nine selected projects in this round will receive nearly $10.5 million and will make a cost-share contribution for a total public-private investment of more than $13.7 million. The projects selected to receive funding will help to further reduce the cost and improve the quality of SSL products:
Carnegie Mellon University (Pittsburgh, Pa.)— Improving the heat-conducting properties of the phosphor used in LEDs, which will increase light output and reduce costs.
Cree, Inc. (Durham, N.C.)— Developing a new low-cost, high-efficiency LED structure by modifying the manufacturing process to reduce processing time and waste.
Momentive Performance Materials Quartz, Inc. (Strongsville, Ohio)— Developing next-generation LED package structures using transparent encapsulants that allow for higher drive current, resulting in increased light output.
OLEDWorks, LLC (Rochester, N.Y.)— Developing cost-effective manufacturing technologies necessary to make high-performance, low-cost OLED panels.
Philips Lumileds Lighting Company, LLC (San Jose, Calif.)—Reducing the cost and increasing the efficiency of LED lighting products by developing a high-voltage LED light engine with a built-in driver.
Philips Research North America, LLC (Briarcliff Manor, N.Y.)— Developing an innovative, energy-efficient LED lighting system for hospital patient suites that takes into consideration health and wellbeing as well as visual needs.
Pixelligent Technologies, LLC (Baltimore, Md.)— Improving the efficiency of OLED lighting by using nanocrystals to increase the light extraction.
Princeton University (Princeton, N.J.)— Increasing the efficiency of OLED lighting on flexible substrates by enhancing the light extraction and removing costly materials.
University of California (Los Angeles, Calif.)— Improving energy efficiency and reducing the manufacturing cost of OLED lighting through the use of an integrated plastic substrate instead of the usual glass with indium tin oxide.
