OLED Wallpaper Could Be the Future of Lighting

It’s the Star Trek -inspired future we were promised—walls that glow and change color, perhaps with just a gentle voice command. And it’s finally (almost) possible thanks to a series of advances in OLED sheets. This new lighting solution also uses half as much energy than existing fluorescent lights. It is, however, pretty expensive. Read more…

LED Tubes Will Make Fluorescent Seem Old Fashioned

Cree, front-runners in the scramble to replace traditional forms of illumination with greener LED sources, has just announced the release of a new type of tube light designed to tackle one of the biggest energy hogs in Corporate America: fluorescent overhead lights. Read more…

Universities inject neuron-sized LEDs to stimulate brains without a burden (video)

Existing methods for controlling brain activity tend to skew the results by their very nature — it’s difficult to behave normally with a wad of optical fibers or electrical wires in your head. The University of Illinois and Washington University have developed a much subtler approach to optogenetics that could lift that weight from the mind in a very literal sense. Their approach inserts an extra-thin ribbon into the brain with LEDs that are about as big as the neurons they target, stimulating deeper parts of the mind with high precision and minimal intrusion; test mice could act as if the ribbon weren’t there. The solution also lets researchers detach the wireless transceiver and power from the ribbon to lighten the load when experiments are over. Practical use of these tiny LEDs is still a long ways off, but it could lead to both gentler testing as well as better treatment for mental conditions that we don’t fully understand today.

Quantum dots help return ‘Triluminos’ RGB LED lighting to Sony HDTVs

While 4K TVs are excellent, for the next couple of years most of us will still be selecting a 1080p model when we’re out shopping, and now we’ve got a little more detail about some of the new ones Sony announced last week . After letting its ” Triluminos ” RGB LED lighting technology fall by the wayside after 2009 because of its high cost, Sony has brought the brand back in this year’s HDTVs. Noted in the press release and highlighted today in the MIT Technology Review , this iteration uses QD Vision’s quantum dot technology to enhance the red/green/blue LED backlighting the series is known for. According to the CTO of QD Vision, the TVs start with a blue backlight — instead of the standard white LED — which stimulates quantum dots that emit “pure green and pure red.” Sony was very proud of its Triluminos tech at the show and our experience at demonstrations seemed to validate the quality of the approach. While we’ve been hearing about quantum dots for years , this is reportedly their first appearance in a mass produced consumer product, once it hits homes we’ll be able to tell if the wait was truly worth it.
