Lighting

Today, DOE Secretary Steven Chu announced the investment of up to $6.4 million (including $4.6 million from the American Recovery and Reinvestment Act) for advancing research and development of next generation high-efficiency lighting.

University of Florida scientists achieved a new record in the efficiency of blue organic light-emitting diodes, or OLEDs. Because blue is essential to white light, the advance helps pave the way to lighting that is much more efficient than compact fluorescents, but can produce high-quality light similar to standard...

Researchers at Auburn University have designed a rechargeable microscope illumination system that can be used by NASA scientists to observe microscopic life in places where there is no electricity. The patent-pending Ilumna 120, which contains a battery pack, condenser, and bulb with a built-in collimator, attaches to...

Engineers at Purdue, Northwestern University, and the University of Southern California have created an active-matrix display using a new class of thin, transparent transistors and circuits. The transistors incorporate nanowires, tiny cylindrical structures assembled on glass or films of flexible plastic that are as thin as...

Martin Schubert - a Rensselaer Polytechnic Institute doctoral student in electrical, computer, and systems engineering - has developed the first polarized light emitting diode (LED), an innovation that could vastly improve LCD screens, conserve energy, and usher in the next generation of ultra-efficient LEDs. Schubert's...

A linear illumination system based on a highly reflective external enclosure improves light efficiency and brightness when utilizing fluorescent lamps, light emitting diodes (LED), laser diodes, organic LEDs, electroluminescent strips, or high-intensity discharge lamps as the light source. The system provides a critical advantage...
