Incandescent bulbs making a comeback, GE still launching new LED lights


On the eve of Christmas 2007, quite a few obituaries for incandescent light bulbs were penned. News was slow, time was short and Congress had just outlined a new energy plan that would essentially force these energy-wasting bulbs out by 2012. Now, however, legions of scientists are racing the clock to develop new incandescents that will still meet the upcoming guidelines, with a Deposition Sciences technology paving the way for a post-2012 model from Philips. Without drowning you in technobabble, let's just say that said tech has seen 50 percent efficiency gains in the lab, which is more than enough to please even the most outspoken tree hugger in Washington. In related news, GE has issued two more LED light bulbs: the 7-watt Energy Smart LED PAR20 and 10-watt LED PAR30. Both of 'em are aimed more at commercial customers than at actual homes, but you'll be hard pressed to find a better option for lighting up your makeshift basketball court.

Sharp's remote controlled LED light-bulbs generate seven-shades of smart

While you're replacing your household incandescent light-bulbs with LEDs in a bid to save energy and possibly cash (over the 40,000-hour lifespan) you might want to consider these remote-controlled lamps from Sharp. The DL-L60AV gives you on/off and dimming functions as well as the ability to adjust the light in seven shades of white to warm up or cool down the glow. Best of all, they screw into a standard E26 socket for a one-to-one exchange with your existing ocean warmers. The features of the remote control are still unclear (lighting zone support, range of operation, etc.) but it appears to work with multiple-lamps in parallel which is a nice touch. However, we'd like to see Sharp integrate a Z-Wave or ZigBee chipset so we could link these directly (without special wall-switches) into a tricked-out home automation and power managment system. The DL-series start at ¥3880 (about $40) for simple LED lights before hitting ¥7980 (about $82) for the fully-equipped DL-L60AV and begin shipping July 15th in Japan.

Ultra-powerful laser could make incandescent light bulbs more efficient


Look, LED light bulbs are fanciful, great for Ma Earth and a fine addition to any home, barber shop or underground fight club. But let's be honest -- even the guy that bikes through blizzards to get to work and wears garb that he grew in his basement isn't apt to shell out $120 a pop to have what's likely the most efficient light bulb American dollars can buy. Enter Chunlei Guo from the University of Rochester, who has helped discover a process which could morph a traditional incandescent light bulb into a beacon of burning light without using nearly as much energy as before. In fact, his usage of the femtosecond laser pulse -- which creates a "unique array of nano- and micro-scale structures on the surface of a regular tungsten filament" -- could enable a bulb to increase output efficiency in order to emit 100-watts worth of light while sucking down less than 60-watts of power. Per usual, there's no telling when this new hotness is likely to hit the commercial realm, but one's thing for sure: we bet GE's paying attention.

First Philips Lumiblade OLED lights arrive


Philips has always pushed OLED lighting concepts, and it looks like the company's Lumiblade products will be the first to start shipping. The folks at OLED-Info got to play with some pre-production samples, and while they're definitely cool and impossibly slim, there are some notable drawbacks: the rectangular panel has some unfortunate "speckles," and overall they're just not very bright on their own, so you'll need quite a few for an actual lamp. Still, we've no doubt OLED lighting will soon be everywhere, so hit read link for a quick glimpse of the future.

LG world's thinnest LCD is only 0.23 inches thick


Looks like we've got a new record holder for world's thinnest LCD, as LG pegs its new 42- and 47-inch models at only 5.9mm thick. Apparently lacking an iPhone for the accepted measurement of thinness, this model was reduced to holding up a coin for an example of LG's edge LED lit prowess. Though you may prefer local dimming LEDs, DisplayBlog is hopeful we'll see a combo of the two lighting schemes bringing thinness and high picture quality next year. Meanwhile, compare these to JVC's magnetically mounted former champ, measuring a now-widebody 7mm thick, but at only 5kg, still holding a weight edge over these two at 6.1 and 7.3kg, respectively. LG promises 120Hz refresh technology and 80% of the NTSC color gamut, up from 72% on standard models, on these, but we'll wait for them to go from the demo stand to the store shelf before revisiting the question of whether thinner and more energy efficient is actually better.

Nanocrystal breakthrough promises more versatile lasers, world peace


For the longest while, scientists have been flummoxed by the incessant coruscating emitted by individual molecules; no matter their methods, they could never quite seem to overcome a troubling optical quirk known sensibly as "blinking." Thanks to a brilliant crew at the University of Rochester, however, we now understand the basic physics behind the phenomenon, and together with a team from Eastman Kodak, a nanocrystal has been created that can constantly emit light. In theory, the discovery could lead to "dramatically less expensive and more versatile lasers, brighter LED lighting, and biological markers that track how a drug interacts with a cell at a level never before possible." Indeed, one could envision that future displays could be crafted by painting a grid of differently sized nanocrystals onto a flat surface, making even OLED TVs look chubby in comparison. Now, if only we had a good feeling that such a device was destined for a CES in our lifetime...

Philips' OLED wall makes its video debut


We already caught sight of some of Philips' new OLED lighting concepts, but when it comes to something like a massive OLED wall there's really no substitute for a proper video, and Philips itself has now kindly provided one for all to enjoy. As you can see for yourself after the break, the wall reacts directly to folks passing by, which turns out to be a surefire to get folks dancing and more generally make fools of themselves -- all in the name of progress, of course. If that's not enough OLED for one day, you can also check out a slightly less entertaining video of Philips' OLED chandelier concept, which is a tad less interactive but considerably more likely to turn into an actual product.

Philips shows off Lumiblade OLED lighting concepts


As promised, Philips has now taken the wraps off its first few Lumiblade OLED lighting concepts which, judging from Philips' boasting, could well change your life and ours. Now on display at the Euroluce International Lighting Fair in Milan, the concepts are divided into consumer and professional groups, the former of which includes ceiling-mounted products like the one pictured above, as well as some slightly more straightforward desk lamps like the one pictured after the break. What's more, each lighting device also boasts at least some degree of interactivity, including the ability to recognize hand gestures or, in the case of the professional lighting fixtures, react to passers-by. Interestingly, however, none of the products are actually full-on OLED lamps, with each also supplemented by some LUXEON Power LEDs to provide some more usable lighting.

Transparent OLED rearview mirror both dazzles and distracts


Although we've been hearing about transparent OLEDs for years now, mum's been the word on an actual product. So far the focus has been on Germany, but it looks like some interesting things have been going down in Korea as well. Researchers at ETRI (the flexible OLED folks) have apparently applied for 51 patents both nationally and internationally for the tech, including one for a transparent oxide resistor that helps increase the aperture ratio of AMOLEDs. And while all this is going down, NeoView KOLON has unveiled a new prototype rearview mirror that utilizes a transparent OLED display for -- well, displaying things. Just be sure to keep your eyes on the road, eh?

Resin replaces ITO in latest flexible OLED prototype


Make no mistake, wrapping your mind around the build of an OLED panel is mighty tough to do. Without getting you mired in technobabble, let's just say that indium tin oxide (ITO) has generally been a mainstay in every single OLED that was produced commercially. Now, a team of researchers from AGFA-Gevaert, IMEC, Holst Centre and Philips have prototyped a 12- x 12-centimeter flexible OLED lighting panel that swaps out the ITO for highly-conductive transparent resin electrodes. You see, it's been difficult for OLED builders to secure enough electrical conductivity of ITO in a low-temperature process, and this new methodology is perfectly suited for the coating method (which makes it ripe for printing). The resin itself is being dubbed Orgacon, and tests have shown it to have a 6x improvement over ITO in terms of electrical conductivity. Beyond that, the crews are keeping the secrets safe from the poachers of the world, but here's hoping this amounts to more than just jovial celebration in a far off laboratory.

GeoBulb LED light bulb uses just eight watts, rings up at $120


Ah, progress. Right around two years ago, we spotted a LED-filled light bulb that used "just" nine watts and cost a staggering $65. Now, we've got yet another option that sucks down even less power and costs nearly twice as much. C. Crane Company has been working on its so-called GeoBulb for a solid three years now, but at long last the device is shipping to affluent homeowners and headstrong Earth lovers. The bulb can provide as much light as a traditional 60W incandescent with just 7.5W, and it features a 30,000 hour (10 years) lifespan with typical usage. Now, the hard part: choosing between cool, soft and warm white.

Scientists purportedly improve blue OLED efficiency by 25%


The holy grail of OLED is upon us. With scientists around the world working to improve efficiency of the short-lived blue OLED in order to better align with lifespans of the green and red counterparts, a team from Pacific Northwest National Laboratory has reportedly taken a huge leap in solving the whole thing. These gurus have conjured up new host materials for a blue phosphorescent OLED that's at least 25 percent more efficient than existing blue OLEDs, but regrettably, details beyond that are few and far between. Word on the street has it that PNNL scientists are expected to gather and discuss the findings before heading to a meeting of the American Chemical Society later this spring, and we'll be crossing our fingers that whatever they've found is both a) cheap and b) easily implementable.

Modistech unveils flexible, ultrathin OLED light in Korea


We just heard that the OLED market was set to skyrocket in 2011, but don't tell Modistech. Said outfit has just revealed its own flexible, ultrathin OLED light module in South Korea, which honestly looks eerily similar to Samsung's "flapping" OLED panels from last fall. Details are pretty scant right now, but we're told to expect mass production within the next year, with public availability penciled in for -- you guessed it -- 2011. Hit the read link for a few more delightful looks.

SmartSwitch prototype makes work out of the simplest of things


Conserving energy is one of those things that you may want to do, but you've never gotten around to it, and you're not exactly sure how to start -- because, well, thinking about stuff is hard. The SmartSwitch prototype -- designed by Peter Russo and Brendan Wypich at Stanford University -- works on just that idea: turning lights on and off is a reflexive action that you barely think about... unless you get some resistance. The modded light switch is equipped with a network connection and a brake pad, and each time you try to turn on a light in your home, it makes a judgment about the overall current electricity levels being used, and gives resistance, making the switch harder to turn on, if the network determines the levels of usage to be high. Check out a video of how the whole thing works after the break.

IKEA starts selling totally hip SOLIG solar lighting devices


We've heard the excuse a gazillion times: "Yo, I want to go solar, but like, where do you even buy this stuff? Oh snap, 0 percent financing on a Hummer H2!" Finally, you can have a solid answer to that very quip (the first part, at least), as household megastore IKEA has begun stocking (in store; online is coming soon) a new series of solar-powered lighting supplies. The SOLIG series contains a handful of solar light sticks, orbs, garden lights, chain globes and even posts, all of which will surely brighten your outdoor patio, flower bed or Earth-friendly RV. Now, if only it were simple to relocate your life to southern Arizona in order to enjoy these more effectively...
