The new LED bulbs can last for 17 years and are expected to outperform currently available products that may be underwhelming consumers right now.

GE has claimed that their new LED bulb is better at directing the light downwards onto the intended area and produces 450 lumens whereas LED bulbs offered by other vendors can only produce 350 lumens. GE has also filed multiple patent applications for the bulb and expects it will be an ENERGYSTAR (News – Alert)-qualified LED omni-directional light bulb.

John Strainic, global product general manager at GE Lighting has commented that this is a bulb that can virtually light users’ kid’s bedroom desk lamp from birth through high school graduation. It’s an incredible advancement that’s emblematic of the imagination and innovation that GE’s applying to solve some of the world’s biggest challenges.

Strainic added that consumers are reluctant to move away from the less efficient incandescent because they prefer the light quality they produce. The new GE Energy Smart LED bulb will address that lighting preference head-on and give consumers yet another option to light their homes and businesses.

GE will put prototypes of the bulb – outfitted with Cree (News – Alert) XLamp XP-G LEDs – on display at two upcoming trade shows: Light + Building 2010 in Frankfurt, Germany, and LightFair 2010 in Las Vegas. The high-efficiency, high-lumen-output LEDs used in the GE bulbs are Cree’s smallest and brightest lighting-class LEDs, designed specifically for general lighting.

Analysts have suggested that the introduction of high-quality retrofit light bulbs, like the GE Energy Smart LED bulb can be the next step in LED lighting revolution.

The bulb will be dimmable and will provide 806 lumens, with the potential to save up to 80% in energy consumption, compared to incandescent bulbs.

Philips said the bulb has a 25,000-hour lifetime.

With federal legislation phasing out inefficient lighting in the years to come, it’s likely that additional LED replacement bulbs will hit the shelves in 2011. Last week GE (NYSE: GE) unveiled its first–a replacement for 40-watt bulbs.

Philips also detailed broader marketing plans for its LED offerings in years to come. The company is introducing a home lighting system called LivingAmbiance, which wirelessly integrates luminaires and lamps to create different light settings–including a range of thousands of different color–with touch-button control.

In 2010, the company will introdue a product platform of outdoor luminaires that it hopes municipalities will adopt for streetlighting.

The company is currently exhibiting its new products and concepts at the Light + Building architecture fair Frankfurt Germany.

and out of the total number sold, around half of them were of the 55″ variety. One of the main reasons this model is so successful is due to the TV’s 2D to 3D feature, where such conversion technology is available to enable users to convert 2D to 3D stereoscopic images with but a single touch of a touch of a button. It would be interesting to see whether the US will see such adoption rates or not.

So what is it about LED TVs that are better?

One of the strong criticisms of LCD TVs has always been the color and contrast. While LCD TVs control a competitive edge over plasma TVs in a lot of areas, the overall black levels of the traditional LCD TV cannot compete. To enhance the experience, manufactures began developing LED LCD TVs that offer a pair of lighting techniques that sharpen up color and contrast levels.

The first, standard edge-lit LED TVs, offer a slightly better lighting technique than a traditional LCD TV in that more powerful, more efficient lights located on the edge of the TV shine inward and diffuse evenly on the screen.

The second, full-matrix LEDs, utilize a technology better known as local dimming that disperse LED light from the back of the TV, instead of the sides, giving it a very even distribution of light. Essentially, the full-matrix technology is able to achieve unmatched color levels and contrast.

The beauty of the LED technology is not just the improved picture quality; LED TVs are more efficient and slimmer than just about any TV on the market. In fact, Samsung’s LED TVs use as much as 40% less power than any equivalent-sized traditionally-lit LCD TV.

Essentially, the best TVs on the market are LED TVs. So, where are the best places to buy the highest-rated LED TVs at the lowest prices?

Highly regarded as one of the best TVs in the last year, the Samsung UN55B8000 55-Inch 1080p 240 Hz LED HDTV has dropped significantly in price as Samsung has already launched many of the enhanced, upgraded C5000, C6000, C7000, and C8000 series models (the C7000 and C8000 are the new 3D LED TVs). Priced as low as $1,823.99, this local dimming model is almost $2,000 less than the suggested retail price, and has moved up to the #1 bestselling LED TV on Amazon.

If 3D LED is the direction you want to go, the Samsung UN55C7000 55-Inch 1080p 240 Hz 3D LED HDTV (Black) has dropped from $3,299.99 to $2,669.00 (more than $600 off a 2010 TV). As mentioned in other Tainted Green reviews, the Samsung 3D LED TVs includes a 2D to 3D converter that instantly changes regular TV into 3D TV. Few large retailers can even get close to this price.

Finally, if value is what you want and you don’t mind a non-Samsung LED TV, Sharp offers the Sharp AQUOS LC40LE700UN 40-Inch 1080p 120 Hz LED HDTV for under $900. The price is right and so far, the reviews have been very positive.

The time is now, when models are changing and prices are dropping, to buy an energy efficient, slimmed down LED TV.

The LX9500 will be the company’s first entry into the 3D market, which has currently become filled by Samsung and Panasonic The LX9500 will be available in both a 47-inch and a 55-inch model.

The 1080p sets will have Skype’s TV platform, USB support, HDMI connections, and support for LG’s USB-powered 3D glasses. It is also decorated with a full backlit display, the first 3D set to do so.

According to the blog Ubergizmo, which translated LG’s Korean press release, the set is planned to be released in Korea next month at around the equivalent of a little over $4,000.

The LX9500 will then make its way to the US and Europe by May.

Early adopters in the 3D TV market have proven that there is significant demand. Panasonic’s first set of 3D TVs sold out across the country within just a week, and Samsung’s sets are also selling through at higher rates than analysts were expecting.

The Livermore, Calif.-based start-up said Wednesday it has designed a lighting module called Helieon that combines Bridgelux’s LED lights and a snap-in interconnect system made by Molex, which is based in Lisle, Ill.

The interconnect system will make it easy to install LEDs and upgrade them when more efficient or brighter lights come out, the companies said.

The Helion system, which will be available in May for $20, is aimed at lighting manufacturers that build actual lighting fixtures. The Helion will be available with a light output between 500 and 1,500 lumens, the equivalent of between 40 watts and about 100 watts for incandescent bulbs but will use significantly less electricity.

Bridgelux says that the packaging and efficiency of its lighting system is a step toward making LED lighting more cost-effective when compared with other forms of lighting. “Solid state lighting is poised to displace conventional incandescent, fluorescent and other technologies in many high-volume general lighting applications,” Bridgelux CEO Bill Watkins, who joined the company earlier this year, said in a statement .

Bridgelux has signed on some lighting fixture manufacturers to use Helieon, including architectural lighting company Focal Point. But as it goes after the general lighting market, it faces competition from a number of LED start-ups and established lighting companies.

The light output and color rendering of this new bulb is the equivalent of the current 60-Watt incandescent bulb available in the market but uses only 12 Watts of energy consumption.

The Diogen Bulb has a lifespan 40 times greater than incandescent and 6 times greater than the current CFL bulbs offered in the market today and is completely safe and is Mercury-free, unlike CFL products.

The colors are more vibrant than you can get in an incandescent, they use up to 98 percent less power than comparable incandescents, and they have a long life. A string of decorative lights will last forever. It can take 50,000 to 100,000 hours of use, well over 20 years.

Also, LED lights are cool to the touch and don’t contain mercury, unlike CFLs — which requires special handling for disposal.

LED’s last about 40 times longer than regular incandescent lights and six times longer than CFLs currently on the market.

It’s great for us because we can afford to go more green — not only from using less power, but also from being able to have enough power to do a show. And we’re over 50 percent with LED lights in the show.

The HV9963 utilizes a closed-loop system to control the current going to the LED string, which is an active, real-time system that continuously monitors the LED current via sense resistors. The HV9963 includes a 1.0MHz transconductance amplifier with a tri-state output, which closes feedback loops in the sensing process and provides accurate current control. It can be synchronized in applications requiring multiple LED drivers to prevent the system sub-harmonic oscillations that are often associated with driving multiple driver schemes.

The HV9963 also features hiccup mode protection for both short- and open-circuit conditions, and a high PWM dimming ratio. The IC operates in a constant frequency mode for use in a variety of converter topologies such as buck, boost and SEPIC.

“The HV9963’s closed-loop system enables accurate line and load control of the LED current over its entire operating range,” states Ahmed Masood, Vice President of Marketing for Supertex. “This IC also includes controls that allow PWM dimming at very low duty cycles, resulting in a contrast ratio of up to 5,000:1.”

The HV9963 is available in a 16-lead SOIC package (HV9963NG-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.85 each for the HV9963NG-G in 1K quantities.

Multiple standardization organization are working on defining and implementing testing and performance standards and communicating them to the public. Solid state lighting is progressing niche by niche.  More municipalities are testing LED streetlight and some have already committed to massive retrofits (200,000 street lights in Los Angeles). Adoption in commercial and retails lighting, while still low in volume is progressing fast (announcements from Wall Mart, Starbucks…). While we all have our eyes focused on residential applications, it’s important to realize that homes are the smallest segments (in term of lumens) compared to industrial, commercial and municipal lighting. However, for most, it remains the ultimate frontier.

But even this application now seems within reach and LED replacement bulbs might come to your home faster that you expected. Don’t rush yet though, as low quality products are still flooding the market and might create a negative initial perception of the technology, a risk that the industry is aware off and trying to control by working on performance standard (make sure you get products meeting or exceeding the Energy star criteria for solid state lighting). In Japan, the largest electronic manufacturers are making a strong push with quality products. Toshiba Lighting and Technology introduced a 60W equivalent replacement LED bulb for JPY9,000 in late 2008. The same product now goes for less than JPY4,000. Sharp launched similar offers and the price is now expected to reach  JPY2,000 in 2010. At this pace, most now expect the cost of LED replacement bulbs to reach the $10 for 1000 lumen target commonly accepted as the “magic” number that will trigger massive adoption by 2012.

In the US, Philips released the first LED bulb to participate to LPrize contest organized by the US Department Of Energy to reward the first 60W replacement LED bulb to meet aggressive performance targets.  A lot of credible light bulb replacements could be seen at the recent Strategies In Light conference exhibition floor and CREE is planning to release a retail version of its award winning LR6. The price point at which it will be released will send a strong signal to the industry.

After riding the cell phone keypads and LCD screen backlight wave during the previous decade, the industry is on for a spectacular growth thanks to large LCD backlight applications. While similar in essence to the smaller LCD screens, the larger displays found in laptops and large flat panel TVs were until recently more difficult to illuminate with LEDs because of their large surface. One must give credit to Sony and Lumileds, now a subsidiary of Philips, for pioneering the field in 2005. However, while delivering outstanding performances, the price of those LED backlit TVs were out of reach (>$10,000) for most consumers. A strong push by Apple, Dell and other brands allowed LEDs to start being adopted in laptops in 2007. In 2010, the adoption of LED for the segment should exceed 80%. But until 6-8 months ago, the industry consensus was that broad adoption of LEDs for large displays (20” and above) was still at least a couple years away. Samsung shook the industry in the second half of 2009 by bringing into the market a flurry of breakthrough products at affordable prices. Thanks to various engineering breakthrough and a strong marketing push (LED TVs anyone??), the unexpected success of the product put large LCD TV 2 years ahead of the initial roadmap and rescued the LED industry from what was going to be its first year ever of negative growth in 2009 (2001 was a flat year).

Since then, All TV manufacturers have jumped into the bandwagons, and LG, Sony, Sharp, Vizio, Toshiba all lined up an impressive series of new LED backlit LCD TV for 2010 with aggressive pricing. The cost of LED backlit TV remains marginally higher than “old fashion” cold cathode fluorescence lamp (CCFL) TV. However the price gap is shrinking and the consumers are falling for those ultra-slim TV with high contrast ratio and in some cases, improved color gamut and reduced motion blur. However, because of the engineering tradeoffs necessary to keep cost under controls however, not all the potential benefits of LED backlit TVs are offered on every set.  But, as technology improves, LED cost decrease and economy of scale become significant, the adoption rate of LEDs in LCD TV is expected to jump from 2-3% in 2009 to more than 20% in 2010 with the most optimistic forecasting 39 millions LED TV sets for the year. The adoption rate should further increase to 70% by 2013 and volumes exceed 150 millions. The exact impact on the LED industry is difficult to quantify though: because of the mix of panel size and the variety of design options (edge lit vs. backlit, white LEDs vs. RGB), estimating the exact number of LED chip per TV set is challenging (it varies from 250 to more than 1,000 on certain models). The one sure thing however, is that LCD TV will carry the LED industry through what analysts call it second growth cycle, possibly slightly restrained by tensions on the Sapphire substrate market and the ability of equipment manufacturers to deliver the record amount of MOCVD reactors to be shipped in 2010 and of the chip manufacturer to install and qualify them on time (it takes3 months to start production on a new reactors and in some cases another 4-6 months is needed get the chips from the new reactor validated by the final customer).

So what about the next big thing for LED: General Illumination? The main barriers to a broad and immediate adoption are still here. Those are essentially:
- Energy efficiency.
- Reliability.
- Color consistency and stability.
- Lack of standardization.
- Confusing supply chain.
- Upfront cost.
