The U.S. Department of Energy (DOE) today announced that DOE will provide up to $20.6 million for a total of 13 projects aimed at advancing solid-state lighting (SSL) research and product development. Combined with industry cost share, investment in these projects will total $28 million. SSL lighting is an advanced technology that creates light with considerably less heat than incandescent and fluorescent lamps, allowing for increased energy efficiency. These projects are part of DOE’s national strategy to accelerate SSL advancements from the laboratory to marketplace to help meet the rapidly growing demand for energy.
“The Department is eager to advance and accelerate research and development in this cutting-edge technology because solid-state lighting has the potential to more than double the efficiency of lighting systems, significantly reduce our carbon footprint and transform the built environment,” DOE Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner said. “Increasing energy efficiency across all sectors is a critical component of the President’s comprehensive strategy to commercialize and deploy advanced technologies to meet our future energy needs in a way that encourages economic growth, enhances energy security and addresses the serious challenge of global climate change.”
Unlike incandescent and fluorescent bulbs, SSL uses a semi-conducting material to convert electricity directly into light, which maximizes the light’s energy efficiency. Solid-state lighting encompasses a variety of light-producing semi-conductor devices, including light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs). Once used only for indicator lights (to illuminate the numbers on digital clocks and light up watches), LEDs are now found in a variety of specialty applications including brake lights, flashlights, traffic signals, and more recently, streetlights. OLED technology is more commonly used commercially, such as in small screens for mobile phones, portable digital music players, digital cameras, and now televisions.
These projects continue DOE’s public/private partnerships on activities that will advance state-of-the-art SSL used for general lighting applications. In addition to R&D support, DOE provides national leadership and support for the development of ENERGY STAR® criteria for SSL products, technology procurement and demonstrations, commercial product testing, buyer/user guidance, design competitions, and standards development.
Selection of these projects represents the fourth round in a series of DOE funding opportunities seeking to examine high-priority research and development (R&D) activities that will advance the state-of-the-art SSL used for general illumination applications. Five of the projects were selected in response to DOE’s Core Technology Funding Opportunity Announcement (FOA), issued in May 2007, and two projects were selected in response to DOE’s National Laboratory Call for Core Technology Research. These seven projects are expected to fill key technology gaps, provide enabling knowledge or data, and represent a significant advancement in the SSL technology base. The total value of these projects is $10.8 million, with performers of cooperative agreements providing 20 percent of total project costs.
The remaining six projects were selected in response to DOE’s Product Development FOA, also issued in May 2007, with a total value of $17.1 million and an average of 32 percent investment from industry. These selections focus on the development and improvement of commercially viable materials, devices, or systems.
