Silicon-based nanoparticles could make LEDs cheaper, greener to produce
(Phys.org) —Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones ...
New family of tiny crystals glow bright in LED lights
(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.
New LED streetlight design curbs light pollution
Streetlights illuminate the night, shining upon roadways and sidewalks across the world, but these ubiquitous elements of the urban environment are notoriously inefficient and major contributors to light ...
New research findings open door to zinc-oxide-based UV lasers, LED devices
(Phys.org) —Researchers from North Carolina State University have solved a long-standing materials science problem, making it possible to create new semiconductor devices using zinc oxide (ZnO) – including efficient ultraviolet ...
Review: 'Smart' LED bulbs controlled by iPhones
LED bulbs seem to be the future of home lighting: They save electricity, they're durable and they don't contain mercury like compact fluorescents. But having them produce white light like any old light bulb ...
Kickstarter project team claims its LED bulb world's most efficient
New material for warm-white LEDs invented
Light emitting diodes, more commonly called LEDs, are known for their energy efficiency and durability, but the bluish, cold light of current white LEDs has precluded their widespread use for indoor lighting.
Duo create GravityLight: Lamp that runs off of gravity (w/ video)
Li-Fi: Edinburgh prof seeds LEDs for communication
Study may lead to less expensive consumer lasers and LEDs
(Phys.org) -- A recent theoretical study by a University of Waterloo doctoral candidate in nanotechnology engineering suggests that manufacturers may one day make lasers and LEDs out of silicon, with the potential to significantly ...
Virtual blue skies brighten the office of the future
There is light at hand for those who toil away in a poorly-lit office. Scientists at the CeBIT high-tech fair have developed a system that gives the feeling of working outside under blue skies.
LED lights point shoppers in the right direction
Looking for an item in a large department store or mall can be like searching for a needle in a haystack, but that could change thanks to a hybrid location-identification system that uses radio frequency transmitters and ...
Sky light sky bright - in the office
Working under the open sky it sounds enticing, but its seldom really a practical option. Now, a dynamic luminous ceiling brings the sky into office spaces by creating the effect of passing clouds. ...
Alternative LED lighting combats energy crisis
Alternative lighting is emerging as a potent method to combat the energy crisis. Light-emitting diode (LED) lighting technologies could provide an innovative way to save energy and make wasteful lighting obsolete.
