Voiding defects: New technique makes LED lighting more efficient
Light-emitting diodes (LEDs) are an increasingly popular technology for use in energy-efficient lighting. Researchers from North Carolina State University have now developed a new technique that reduces defects in the gallium ...
LEDs promise brighter future, not necessarily greener
Solid-state lighting pioneers long have held that replacing the inefficient Edison light bulb with more efficient solid-state light-emitting devices (LEDs) would lower electrical usage worldwide, not only "greenly" decreasing ...
Care for some light music? LEDs make it possible
(AP) -- Light-emitting diodes, or LEDs, are starting to become cost-effective alternatives to standard light bulbs and fluorescent tubes. That opens up some interesting possibilities, such as the combination ...
New alloys key to efficient energy and lighting
A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight, and to better light-emitting diodes (LEDs) that could replace ...
LED streetlights best buy for cities, researchers report
University of Pittsburgh researchers have conducted the first cradle-to-grave assessment of light-emitting diode (LED) streetlights and determined that the increasingly popular lamps strike the best balance between brightness, ...

Innovation doesn't always carry a big brand name
The giants of the electronics industry make the big splash at the Consumer Electronics Show, as usual, with towering displays, celebrity spokespeople (Taylor Swift sang for Sony, live and in 3-D) and invitation-only soirees.
Sony optimistic on 3-D TVs, in-house display
(AP) -- A third to a half of the Sony Corp. TV sets sold annually will be packed with 3-D features by the year ending March 2013, a senior executive said Thursday.
LED light bulbs yield big savings in energy
One way the United States could slash its electricity use, dependence on fossil fuels and emissions of heat-trapping gases is really quite simple: better light bulbs.
LED closes the yellow gap: Full conversion of blue into amber light by new nitride phosphor
(PhysOrg.com) -- Monochromatic light-emitting diodes cover a large part of the visible spectrum with high effi-ciency. For blue light, nitride diodes achieve external quantum efficiencies in excess of 65%, ...
