DOE Awards $15 Million for Next Generation Energy-Efficient Lighting
June 8, 2011
DOE is boosting research that can lead to such innovations as Philips Lighting's 12-watt substitute for a 60-watt incandescent bulb, shown here unlit (left) and lit (right).
DOE announced on June 7 nearly $15 million will go toward support of eight new research and development projects that will speed up development of high-efficiency solid-state lighting technologies such as light-emitting (LEDs) and organic light-emitting diodes (OLEDs). The selected projects, in Arizona, California, New York, and North Carolina, will leverage an additional $4 million in private sector funding. LEDs and OLEDs, which use an emissive electroluminescent layer of organic compounds, have the potential to be ten times more energy-efficient than conventional incandescent lighting and can last up to 25 times as long.
The selected research is focused on advancing core technology, developing new products, and expanding domestic manufacturing capacity. For example, Arizona State University Tempe will attempt to demonstrate an efficient, stable white OLED using a single emitter, which will simplify the device structure and in turn reduce costs for the consumer. And, Philips Lumileds Lighting Company, LLC in California will use high-voltage, low-current LED designs, to simplify driver requirements, improve driver efficiency, and reduce system cost. This is the seventh round of DOE funding for solid-state lighting core technology research and product development, and the second time that DOE has funded solid-state lighting manufacturing projects. See the DOE press release, the list of selected projects, and the Solid-State Lighting Program website.
