technology


One of the more fun new technologies I saw at the TED conference this week was a demo of the newest form of 3-D film, seen behind glasses from RealD Cinemasony-glasses1These are the RealD glasses they gave us at TED.  They work and with no dizziness, headache, or other bad side-effects.  We saw a sampling of concerts (Bono), music videos, sports events, etc., all in 3-D, and the images were realistic and truly fun to watch.  There were a few gimmicky moments, such as when Bono extended his hand forward and it hovered as if outside the frame of the screen.  But overall, the effect of the 3-D simulation drew the viewer more into the experience of the film-making.  The best use of the 3-D in my opinion was for sports games. It was very cool to see football in 3-D for instance. I’m sure my football-playing son and his friends would love to watch games in 3-D if they couldn’t be there live.

As I’ve written about before on this Blog, OLED televisions are coming soon and in combination with the 3-D simulation, this will revolutionize the television watching experience exponentially.  Sony OLED television is likely to lead the way and Sony partnered with RealD Cinema on the TED presentation.  I can only imagine what RealD and Sony will accomplish together for full-size film experiences.  Their partnership may revitalize in-theater movie watching more than anything else has in a long time.

Nichia and Luminus Devices have signed a cross-licensing and manufacturing agreement to help bring white light LEDs to market. 

White LEDs – If you cover a blue LED with a yellow phosphor you get white light.  The deal also unites the oldest and one of the newest names in white light LEDs.  Nichia is a big LED manufacturer with an extensive sales network.  Luminus sells the PhlatLight LED.  Under this new deal, both companies will sell PhlatLights beginning in 2009.

There are two ways of producing high intensity white-light using LEDs. One is to use individual LEDs that emit three primary colors – red, green, and blue, and then mix all the colors to produce white light. The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, much in the same way a fluorescent light bulb works.

Lighting consumes 22 percent of the electricity in the U.S.  traditional lights are incredibly energy efficient. Incandescent bulbs waste 95% of the energy put into it. The rest is converted to heat. LEDs save up to 90% of the energy costs of lighting.

This deal will help produce better LEDs more efficiently. Rather than make small LEDs that might measure 1 millimeter a side and take up a little more than a square millimeter in area, the company makes devices like its PT120 that can sport 12 square millimeters of light emitting surface(that’s 4.6 x 2.6 millimeters). A larger LED means that fewer LEDs are needed to produce a lamp, which in turns leads to higher efficiencies.

 Nichia engineer Shuji Nakamura invented the blue LED while at NIchia during the 1990s. Later, Nakamura did the unthinkable in Japan: He sued his employer for shorting him financially for the invention. He ultimately settled for millions and became a folk hero to salarymen in Japan.  Nakamura is now a professor at the University of California Santa Barbara and is behind two Khosla Venture-backed startups: Soraa and Kaai.

Illuminated clothes with LEDs

At LEDinsider.com, we’re not offering LED clothes…yet!  But maybe that will be a future development. What do you think!?!

Each one of Lumigram’s Lumitop fiber optic tops is powered by a compact battery pack connected to a bright LED light source.

Cambridge University’s Centre for Gallium Nitride has developed a new way of making GaN which could produce LEDs for a tenth of current prices and see household lighting bills reduced by up to 75 percent within five years.  

The Gallium Nitride LED bulbs do not contain mercury, a neurotoxin contained in CFLs that many associate with migraines, brain damage and epileptic fits, like CFL bulbs do.  GaN LEDs also are dimmable, do not flicker and reach maximum brightness as soon as they are switched on. Gallium Nitride LEDs could lower energy consumption for lights from 5 to 20 percent. 

 

 

A GaN LED can burn for 100,000 hours . They can also last
100,000 hours, which is about 1
0 times as long as fluorescent lamps, and would cost $3 each, a huge cost-savings over more expensive LEDs. 

 

This new generation of GaN LED lighting promises to be
three times more efficient than commercially-available fluorescent lighting. 
The new LEDs use Gallium Nitride (GaN), a man-made semiconductor that emits a brilliant
bright light but uses very little electricity. Until now, high production costs have made GaN lighting too expensive for widespread use in homes and offices.

The new technique grows GaN on silicon wafers, which achieves a 50% improvement in cost and efficiency on previous approaches to grow GaN in labs on expensive sapphire
wafers that have been the method of manufacture since the 1990s.

GaN lights could well be just we need to provide our lighting needs more cost-effectively and energy-efficiently for the future. Scientists are very close to achieving highly efficient, low cost white LEDs that can take the place of both traditional and currently available low-energy light bulbs. That won’t just be good news for the environment, it will also benefit consumers by
cutting their electricity bills.”

 

 Sony Bravia XEL features an OLED screen, measuring just 3mm thick


World's thinnest TV ? slimmer than a pound coin, but costing 3,489 of them   


The world’s thinnest television goes on sale, measuring a mere 3mm, no thicker than a penny, but costing thousands of them.

Sony’s Bravia XEL promises to transform the television industry, despite its high price, by offering viewers the crispest, most colorful pictures ever seen. Because it has such a lightweight screen, Sony predicts the Bravia XEL model will revive the idea of portable televisions, with users being able to move the TV from room to room like a laptop.  Indeed, the Sony will give portable and easily used laptop television a run for the money.

The XEL is the first Organic Light Emitting Diode (OLED) television to come to market and uses completely new technology from previous flat screen models such as LCD and Plasma.

Normal flat screen televisions use a backlight to produce the picture on screen, but OLED screens actually emit their own radiance, which means the blacks are pure black, rather than the dark grey you get on most televisions.  All those who see and compare OLED TVs to even the best of LCD and Plasma gasps at how realistic OLED  is. Indeed, OLED has been described by many as being BETTER than reality.

The contrast ratio on a good LCD television is about 30,000 to one. On the OLED it is 1 million to one.

OLED televisions were first unveiled as a prototype a year ago, but Sony is the first company to start selling them to consumers. However, because the technology is still so expensive and fragile, the biggest screen available is just 11 inches wide.

Wow is all I can say!  Eaglelight.com has an exclusive on the most incredible flashlight I’ve ever seen. It’s only 4 inches long and feather light, but it packs the biggest punch of light imaginable.  It’s also Waterproof, shock proof and ultra-light and compact.

It’s a ZOOM flashlight by LEDinsider.com and the range is really something to behold. It goes from 4 degrees to 30 degrees and when it’s in the sharp, focused beam, the light must shoot out at least 300 feet! We love to shoot the light out into a dark night and illuminate trees and hills far from our house. 

For safety if nothing else, this flashlight is something everyone should have in their emergency preparedness kit.

The flashlight runs on 3 AAA alkaline batteries and comes with a convenient wrist strap and storage pouch, plus a very nice gift box.  I’m going to give this flashlight to everyone in my family. It’s under $50.

Your LEDinsider team was in China last year to see their LED developments. Their colorful LED lighting displays in places like Shanghai are a wonder to behold!

China's Huge Solar-Powered LED Wall

It’s called the GreenPix Zero Energy Media Wall, and it has 2,292 individual multi-colored LEDs. Comparable to a 24,000 sq. ft. monitor screen, the GreenPix Energy Media Wall is said to be the largest color LED display in the world. 

Featuring the largest color LED display worldwide and the first photovoltaic system integrated into a glass curtain wall in China, the building performs as a self-sufficient organic system, harvesting solar energy by day and using it to illuminate the screen after dark, mirroring a day’s climatic cycle.  

The LED Zero EnergyMedia Wall is also forms an integral part of the ecosystem of the building.  The polycrystalline photovoltaic cells are laminated within the glass of the curtain wall and are placed with changing density on the entire building’s skin. The density pattern increases the building’s performance, allowing natural light when required by interior program, while reducing heat gain and transforming excessive solar radiation into energy for the media wall.

The building was finished in time for the 2008 Summer Olympic Games as part of the Xicui Entertainment Complex in Beijing.  The building opened to the public on June 24, 2008, with a specially commissioned program of video installations and live performances by artists from China, Europe and the US.
