The National Energy Technology Laboratory (NETL), on behalf of the U.S. Department of Energy (DOE), is pleased to announce the selection of five applications in response to the Solid-State Lighting Product Development Funding Opportunity Announcement (FOA) DE-PS26-05NT42480. The objective of the FOA is the systematic use of knowledge gained from basic and applied research to develop or improve commercially viable materials, devices, or systems. The five selections are anticipated to significantly contribute to the goal of the SSL program:
By 2025, develop advanced solid-state lighting technologies that, compared to conventional lighting technologies, are much more energy efficient, longer lasting, and cost competitive by targeting a product system efficiency of 50 percent with lighting that accurately reproduces sunlight spectrum.
The present selections represent the second round of Solid-State Lighting announcements focused on the development of products. Product development encompasses the technical activities of product concept modeling through the development of test models and field ready prototypes. The technical activities are focused on a targeted market application with fully defined price, efficacy, and other performance parameters necessary for success of the proposed product. The new selections are covered under the Exceptional Circumstances Determination issued by DOE in June 2004.
The selections are listed below (subject to negotiation):
Recipient: Color Kinetics Incorporated
Title: An Integrated Solid-State LED Luminaire for General Lighting
Summary: This proposal seeks to develop replacement lamps for 60 watt incandescent light sources with a 4x increase in efficacy to 80 lumens per watt. The proposal targets package and system integration technology through the development of a novel hybrid-LED source which combines direct emission sources with phosphor down converted emissions.

Recipient: Eastman Kodak Company
Title: OLED Lighting Device Architecture
Summary: The objective of the proposal is to increase performance in OLED devices to 50 lumens per watt at 1000 cd/m 2. This will be accomplished by focusing on light extraction efficiency enhancement, low operating voltage materials and structures, high quantum efficiency and stable white emitters, and stacked-architecture techniques.

Recipient: General Electric Global Research
Title: Phosphor Systems for Illumination Quality Solid State Lighting Products
Summary: The proposal seeks to build upon previous successful work that incorporates the use of novel nanophosphors to create white light from violet LEDs. The target is the replacement of incandescent light sources reaching 96 lumens per watt at color rendering indexes in excess of 80.

Recipient: OSRAM SYLVANIA Development Inc.
Title: Phosphor White LED with High Package Extraction Efficiency
Summary: The proposal seeks to increase the external quantum efficiency using remote phosphors and employing a multi-layer thin film coating technique to increase the probability that scattered light will escape out of the device. The team targets 80 lumens per watt as an end device.

Recipient: SRI International
Title: Cavity Light-Emitting Diode for Durable, High-Brightness and High-Efficiency Lighting Applications
Summary: The proposal seeks to develop cavity OLED devices in which the cavities are filled with a light emitting polymer. The result is an increase in efficiency by channeling light out of the device thereby reducing optical loss. The team goal is a 5x increase in the external quantum efficiency over standard OLEDs at twice the brightness.
