Philips eases switching fluorescent tubes with LED replacements
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 ...
Shanghai prof claims Li-Fi advance, prepares show kits
Using nanophotonics to reshape on-chip computer data transmission
A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able ...
Physicists observe 'campfire effect' in blinking nanorod semiconductors
When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased ...
Quantum-dot LED screens may soon rival OLEDs and LCDs
LEDs: Better red makes brighter white
Chemists at Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a novel type of red phosphor material, which significantly enhances the performance of white-emitting LEDs.
Breakthrough research produces brighter, more efficiently produced lighting
By determining simple guidelines, researchers at UC Santa Barbara's Solid State Lighting & Energy Center (SSLEC) have made it possible to optimize phosphors –– a key component in white LED lighting –– ...
Kickstarter project team claims its LED bulb world's most efficient
Li-Fi: Edinburgh prof seeds LEDs for communication
Student's flashlight works by body heat, not batteries
Lighter, cheaper, LED light bulbs are starting to enter the marketplace
Just when you were finally warming up to the idea of swapping out your old light bulbs with compact fluorescent ones, you may soon find a new alternative at your local hardware store.
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 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.
