They call it 'wellbeing.' Or is it the spy that came in from the cold?
LEDs may have the near future sewn up as far as light sources go, but what about the light switch? Lux takes a look at the technologies poised to take its place.
It's a mixed bag for organic light-emitting diodes. They're improving and prices are dropping, but LEDs will stay ahead of them until the next big thing comes along, according to a new research note.
Not content with winning a Nobel Prize for his blue LED, which kicked off the LED lighting revolution, Shuji Nakamura now plans to shake up the world of 'human-centric' lighting with new technology based on violet LEDs.
If you want a Nobel Prize, you have to meet lofty expectations. So what has the blue LED done to earn its inventors the grand honour? For starters: It is bringing light to millions of people with no electricity.
It looks like the sun... but it isn't. It's a brand artificial skylight which, for the first time, recreates the scientific phenomenon that makes the sky appear blue.
Earlier this week we wrote that office workers confined to spaces away from natural light are tired and weary compared to their colleagues by the window, as a U.S. study observed.
Now, like the proverbial string of buses, another study has come right along revealing the same general effect and more: People who work near the window laugh more.
The US Department of Energy is funding nine research and development projects to help accelerate the development of high-quality LED and OLED technology.
