PERKINELMER TO DRAW ON OSRAM LED PATENTS PerkinElmer Optoelectronics, specializing in digital imaging, specialty lighting, and optical detection technologies, has signed a licensing agreement with Osram Opto Semiconductor allowing the company to access Osram Opto's white light-emitting diode (LED) patents for the manufacture of LED components in lighting solutions.
LEMNIS JOINS CLINTON CLIMATE INITIATIVE The Clinton Climate Initiative has selected Lemnis Lighting as a supplier of LED retrofit lamps within the organization's purchasing consortium network of providers, created to give cities around the world access to energy-efficient technologies at lower prices.
MARTIN AWARDED DEVELOPMENT GRANT Martin Professional A/S was awarded a technology grant from the Danish National Advanced Technology Foundation for the development of new LED technologies through the company's INLED (Intelligent Light Emitting Diodes) project. Martin will receive $3 million in funding from the foundation, contribute $2 million itself, and receive $1 million from its partner, Aalborg University in Aalborg, Denmark.
SCHREDER TO DEVELOP LED STREET LIGHTING FOR U.S. Drawing on the solutions developed for a recent street lighting project in Split, Croatia, Schreder Lighting USA plans to initiate and implement high-quality, performance-based LED street lighting for the American specification market. The company used Cree's warm-white XLamp XR-E LEDs to create streetlights that deliver the warm-white light, brightness, color stability, and uniformity necessary for the project, Schreder says.
DOE RELEASES ROUND 4 TESTING RESULTS In January 2008, the U.S. Department of Energy (DOE) released to the public the summary report of Round 4 Commercially Available LED Product Evaluation and Reporting (CALiPER) product testing results. In Round 4 of the testing program, 20 products were evaluated—15 SSL replacement lamps and luminaires and five fluorescent or halogen-lamped luminaires—as a benchmark. The summary report can be downloaded for informational and educational purposes only at www.netl.doe.gov/ssl/comm_testing.htm.
OSRAM ACHIEVES OLED MILESTONE Osram Opto Semiconductors says it has developed a warm-white organic light-emitting diode (OLED) that achieves record values of efficiency, lifetime, and brightness, proving that it is possible to improve efficiency and lifetime simultaneously without sacrificing one for the other. The Osram flat OLED light source has an efficiency of 46lm/W and a 5,000-hour lifetime, at a brightness of 1,000cd/m2, with a color rendering index of 80. The company expects to produce an energy-saving flat OLED light module of several tiles by March 2009 that will deliver an overall luminous flux of 500lm using less than 10W.
GE SUCCESSFULLY ROLL-PRODUCES OLEDS GE Global Research says it has successfully demonstrated the world's first roll-to-roll manufactured OLED lighting devices, a process similar to that of newspaper printing, proving that low-cost production of OLEDs is possible. The research project was a four-year, $13 million collaboration between GE Global Research, Energy Conversion Devices, and the U.S. Commerce Department's National Institute of Standards and Technology, with the goal of demonstrating a cost-effective system for mass producing organic electronics products.
GRAD STUDENT DESIGNS INNOVATIVE LED LAMP Clay Moulton, a 2007 masters of science in architecture graduate of Virginia Polytechnic University, won second place in the Greener Gadgets Design Competition at the 2008 Greener Gadgets Conference in New York City for his design of a gravity-operated, LED-based lamp called Gravia. The 4-foot-tall acrylic column of the lamp glows from the light of 10 high-output LEDs when activated; electricity is generated by the slow fall of a mass object that spins a rotor. Operation is completely silent and cord-free. Moulton designed the lamp when he was an industrial design graduate student.
LIGHTING RESEARCH CENTER AWARDS ASSIST SCHOLARSHIP The 2007-08 recipient of the Rensselaer Polytechnic Institute's Lighting Research Center ASSIST Scholarship is Tianming Dong, a third-year Ph.D. student whose research is focused on understanding the thermal issues of high-power LEDs and developing thermal management strategies for LED light fixtures.
RENSSELAER STUDENT DEVELOPS POLARIZED LED Martin Schubert, a doctoral student in electrical, computer, and systems engineering at Rensselaer Polytechnic Institute has developed the first polarized LED, which better controls the direction and polarization of emitted light. Though ideally suited to liquid crystal displays, computer screens, and other backlighting unit applications, Schubert says his polarized LED also could be used for street lighting applications. This innovation has earned Schubert the $30,000 Lemelson-Rensselaer Student Prize.
