Color of OLEDs can now at last be predicted thanks to new modeling technique
OLEDs – thin, light-emitting surfaces – are regarded as the light sources of the future. White OLEDs consist of stacked, ultra-thin layers, each emitting its own light color, all together resulting in ...
Lighting experts push for LED quality standard
(Phys.org)—It is not enough to be energy efficient; LED lighting also must be consistently high quality and reliable to win over consumers.
'Sensorless sensing' technology enables accurate correction of temperature effects on LED performance
When comparing LEDs to incandescent light bulbs, there is a noticeable difference in light quality: LED lamps when dimmed are perceived to be "colder" than incandescents. At CES 2013 this week, NXP Semiconductors ...

The dark side of kerosene lamps: High black-carbon emissions
The small kerosene lamps that light millions of homes in developing countries have a dark side: black carbon – fine particles of soot released into the atmosphere.
Let there be clean light: Kerosene lamps spew black carbon, should be replaced, study says
(Phys.org)—The primary source of light for more than a billion people in developing nations is also churning out black carbon at levels previously overlooked in greenhouse gas estimates, according to a ...
LED replacements hit stores empty of 100W bulbs
(AP)—The first LED bulbs that are about the same size and brightness as regular 100-watt bulbs are reaching stores. They provide an alternative to compact fluorescents after the federal government banned the production ...
New LED bulb enables wireless light control, personalized with smartphone or tablet app
Building on its innovation capabilities, today Philips unveils hue, the world's smartest web-enabled LED home lighting system. Philips hue signals a new era in home lighting both in the way we think about ...
LEDs winning light race to save energy, the environment: report
Today's light-emitting diode light bulbs have a slight environmental edge over compact fluorescent lamps. And that gap is expected to grow significantly as technology and manufacturing methods improve in ...
Smarter lighting would save $110 billion, summit told
Efficient lighting would save $110 billion a year worldwide, according to a UN-led study published at the Rio+20 summit on Thursday.
Scientists predict paradoxical laser effect
New laser-effect, discovered by scientists from the Vienna University of Technology, Princeton, Yale and ETH Zurich: If coupled, lasers can switch each other off, leading to a "laser blackout".
New malaria method could boost drug production
German scientists have developed a new way to make a key malaria drug that they say could easily quadruple production and drop the price significantly, increasing the availability of treatment for a disease that kills hundreds ...
