Powerful mini-LEDs for thin touchscreens
Osram Opto Semiconductors has developed an infrared light-emitting diode (IRED) for use in very thin optical touchscreens. Called the SFH 4053, the small new lamps are housed in a frame surrounding a display. ...
Manufacturing method paves way for commercially viable quantum dot-based LEDs
University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither.
India's rural poor give up on power grid, go solar
(AP) -- Boommi Gowda used to fear the night. Her vision fogged by glaucoma, she could not see by just the dim glow of a kerosene lamp, so she avoided going outside where king cobras slithered freely and tigers carried off ...
Artificial light quality affects herbivore preference for seedlings
In horticultural production, growers often depend on systems that use artificial light to produce high-quality transplants. Although the systems are efficient, fluorescent lamps can produce plants with shorter shoots than ...
One million Bangladesh homes on solar power
The number of households in electricity-starved Bangladesh using solar panels has crossed the one million mark -- the fastest expansion of solar use in the world, officials said Wednesday.
Kenyan's mission: solar lamps to empower the poor

Marvelous light from conductor paths
Organic light-emitting diodes are seen as the basis for a new generation of lamps: Large-area lamps that can be randomly shaped and fl exibly integrated into interior design. But the "illuminated glass" is ...
Energy saving lamp is eco-winner
In a new study, EMPA researchers have investigated the ecobalances of various household light sources. In doing so not only did they take into account energy consumption, but also the manufacture and disposal processes. They ...
Rotating high-pressure sodium lamps provide flowering plants for spring markets
When consumers visit garden centers in spring they will most likely buy flowering ornamental plants that are ready for their home gardens. Studies have shown that consumers favor plants that are already in ...
Lightbulbs: The more efficient they get, the more light we use
This is a cautionary tale about a few porch lights. Once upon a time, porch lights had incandescent bulbs. Eventually, many residents subbed them out with those swirly compact fluorescent bulbs, which use a quarter of the ...
ORNL graphite foam technology licensed to LED North America
Technology developed at the Department of Energy's Oak Ridge National Laboratory that extends the life of light-emitting diode lamps has been licensed to LED North America.
