LED startup Switch Lighting hopes to light the way in Silicon Valley
Silicon Valley is known for computer chips, software companies and social networks - but not light bulbs.
'Low tech' light in neutron beam illuminates photosynthesis in bacteria
(PhysOrg.com) -- Researchers at the Bio-SANS instrument at the High Flux Isotope Reactor are getting a leg up in their research from an ingenious "low tech" lighting tool that can be fixed to their samples ...
A touch of gold makes glass more see through
(PhysOrg.com) -- Physicists at the King's College London have discovered a means of making glass more transparent - by coating it in a thin layer of gold.
Cancer detection from an implantable, flexible LED
Can a flexible LED conformably placed on the human heart, situated on the corrugated surface of the human brain, or rolled upon the blood vessels, diagnose or even treat various diseases? These things might ...
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.
Data are traveling by light
Regular LEDs can be turned into optical WLAN with only a few additional components thanks to visible light communication (in short, VLC). The lights are then not just lighting up, they also transfer data. ...
Samsung LED seeks US import ban on Osram products
(AP) -- A Samsung unit is raising the ante in a patent dispute with a German rival over energy-saving LED lighting amid intensifying legal disputes among global companies jockeying for supremacy in key consumer technologies.
Philips shows of glowing wallpaper
Panasonic releases a solar charger with USB, AA battery slots and LED lights
Nanowires offer opportunities for improved LEDs
Researchers from Dutch FOM Institute AMOLF, together with colleagues from Philips Research, Eindhoven University of Technology and Delft University of Technology, have made special nanostructures that could ...
US lightbulb rules spark new political fight
With a January deadline looming on a US law mandating energy efficiency standards for lightbulbs, some political forces don't want to turn out the lights.
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 ...
Providing light to individuals who do not have access to a power grid
As part of the Change the World Challenge competition sponsored by the Office of Entrepreneurship each semester, Rensselaer students select a topic from a range of challenges with the potential to improve ...
