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.
Researchers roll out a new form of lighting
In this month's edition of Physics World, Paul Blom and Ton van Mol from the Holst Centre in Eindhoven describe a way of creating thin, flexible sheets of organic light-emitting diodes (OLEDs) using a cheap, newspaper-style "roll- ...
Samsung researchers announce breakthrough in growing gallium nitride LEDs on glass
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.
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.
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. ...
Philips shows of glowing wallpaper
Panasonic releases a solar charger with USB, AA battery slots and LED lights
Researchers create a smaller, flexible LED
University of Miami professor at the College of Engineering, Jizhou Song, has helped design an light-emitting diode (LED) light that uses an array of LEDs 100 times smaller than conventional LEDs. The new device has flexibility, ...
LED bulbs hit 100 watts as federal ban looms
Two leading makers of lighting products are showcasing LED bulbs that are bright enough to replace energy-guzzling 100-watt light bulbs set to disappear from stores in January.
