the best suitable design is guaranteed due to the degree of freedom of placement

It is possible to use Acriche products on AC power freely between 100V and 230V without additional conversion. Only a simple, inexpensive diode bridge is required.Different than other Acriche products (such as the popular A2 and A3 series), the A4 uses 50Vrms per package and 110V-220V can be achieved by connecting multiple devices in whatever manner is needed.Whether used in light bulbs or light structures with arrays of led high bay light, the best suitable design is guaranteed due to the degree of freedom of placement and configuration of the A4. Their total luminous fluxes are 350lm and 270lm, respectively. And the general color rendering indices are 70 and 80, respectively.

Lighting product line featured in their LED offering

Recently, AUO invested some $77 million in purchasing MOCVD equipment for the expansion of Lextar’s LED chip equipment. Since Lextar still operates on a smaller scale, the LED chips used in AUO’s panels are still acquired from Japan and other LED chip suppliers in Taiwan. However, as AUO’s demand booms, the supply will be filled from within the group. Notably, as Lextar’s production of LED chips ramps up, it might impact LED chip makers Epistar and FOREPI heavily. By the end of 2010, AUO plans to fully adopt LED backlight in its notebooks, generating remarkable demand.

In addition to the rapid expansion of its LED chip production, AUO is simultaneously increasing its LED packaging capacity, including expansion plans for LightHouse Technology and Wellypower Optronics. The move is aimed at completing the integration of its LED upstream and downstream supply chain.LED lamps and marking the entrance into the LED lighting market for yahamlighting.com.We're glad to be working with Nexxus to make this major addition to our product lineup," said Mike Connors, CEO of yahamlighting.com.

prevents heat deterioration of the emitter

The coated type production process of organic EL devices, compared with the deposition type, is attracting keen attention because it consists of a few layers formed by coating polymer without the use of vacuum, providing the opportunity for substantial cost reductions and for the production of large area-emission panels in the future.

The new structure has introduced a layer of dielectric/heat conductor that adjusts reflection of light. The new layer helps reduce the percentage of light trapped in the device, improving the light output. The dielectric/heat conductor layer, having high heat dissipation efficiency, prevents heat deterioration of the emitter, prolonging the device life.

SDK has already achieved a luminance half life of approximately 10,000 hours for white lighting through improvements in the phosphorescent-polymer materials.  The company will continue working with SRI International, a non-profit research organization based in California, U.S.A., and Itochu Plastics Inc. (CIPS), to improve the design of device structure and start selling samples on a full scale in 2010 for use in the general lighting market. The three parties will also work to improve coating property of the phosphorescent polymer and prolong the device life, aiming to achieve a 150 lm/W emissive efficiency and a luminance half life of approximately 50,000 hours for white lighting by 2015.

The core value of this project is the manufacturing of solid state lighting materials

The solid state lighting joint venture project between Hebei provincial government and China Electronics Technology Group Corporation’s No. 13 research institute has officially begun its production. This project is located in the Information Technology Center in Shinjiazhuang City, Hebei Province. The investment totaled RMB390 million, and covers an area of 60 acres, and is the largest industrialized solid state lighting project in Northern China. The project is to achieve an annual output of 100 thousand ultra-bright AllnGaP LED epi wafers, 20 thousand GaN LED epi wafer, five billion LED chips and a total of 300 million single-LED lights, standard LEDs, and high-power LEDs. The project is estimated to generate an annual output value of RMB 407 million.

The core value of this project is the manufacturing of solid state lighting materials and chips, which leverages packaging as its technical support, and champions its applications to spur the development of materials, packaging, and chips, and commissions the testing and standardizing platforms of No. 13 institute. The project aimed at making a leap of innovation, accelerating technological progress, and establishing the solid state lighting industry chain in Hebei Province.

CEO Stephen Squires explained that there are essential similarities between the screen-printing techniques to fabricate LEDs and the screen printing technology that Solterra is currently optimizing to print quantum dots to make thin-film solar cells.

Using this licensing agreement to fabricate LEDs using screen printing techniques will greatly reduce the costs of LEDs, Squires explained. The high cost of producing LEDs has limited its uses; and therefore a dramatic cost reduction will greatly expand LED use, he added.

It's important to save energy for the sake of cost and the environment

Since the first light bulb was invented in the 1800’s new lamp technology has evolved. When the fluorescent tube was invented in 1929, sales of traditional light bulbs plummeted, and then in the 1970’s along came the compact fluorescent, since then new variations have evolved, sales of the former types have virtually disappeared, but the fundamental lamp design has remained unchanged, using a heating element to ignite gases and produce light. The use of a heating element results in energy being wasted as heat as opposed to generating light.

As LEDs do not rely on the use of a heating element, then energy is not wasted. The T8 LED tubes from Neo Neon offer a lumen efficiency in excess of 70 Lumens per watt.

The 600mm T8 LED tube draws just 13 watts compared to the typical 21 watts drawn by a fluorescent tube of the same size. The 1200mm version draws only 26 watts compared to the 42 watts of associated size of fluorescent tube.

It's important to save energy for the sake of cost and the environment, and by simply changing the tubes in existing fittings the new T8 LED tubes from Neo Neon can cut nearly 40% off the energy consumption of a typical office lighting installation.

Unlike fluorescent lamps, the T8 LED Tubes from Neo Neon provide 100% light output within milliseconds of switching on the power, making them perfect for connection a PIR sensor and therefore saving even more energy.

Combining these massive energy saving characteristics with the operational life of over 50,000 hours, which will virtually eliminate maintenance costs, the new T8 LED Tubes from Neo Neon will save you money from the day of installation and for years to come.

The core value of this project is the manufacturing of solid state lighting materials

An optional remote control device is available used with the device’s IR receiver. light-drive elite can also work with fixtures that are driven by PWM or DALI using e:cue’s dmx2pwm and dmx2dali interfaces.The K Nova features a 120° emission angle and an low thin package profile of only 2.0mm, and is designed to ensure high luminous efficacy using the latest chip technology, according to the company. At an operating current of 700mA this light source can achieve an impressive brightness of typical 90lm. This high light output allows smaller number of LEDs in various applications where a high luminous flux value is required.

the patented packaging technologies are chosen to optimize light

Seeking out opportunities to reduce energy consumption is just one way AT&T is working to tackle environmental issues. AT&T recently announced plans to invest up to $565 million as part of a long-term strategy to deploy more than 15,000 alternative-fuel vehicles over the next 10 years. AT&T also has begun to use alternative energy sources such as wind and solar power.a solid-state lighting company specializing in high performance LED products, introduces an ultra-bright, ultra-compact 40W LED light source available in warm, neutral and daylight white color temperatures. It is the first of its kind with record luminous flux density in a compact 9mm x 9mm footprint. The multi-chip LED is capable of 2000+ lumens in neutral and daylight white color temperatures and 1500+ lumens in warm white.

This industry-leading LED is an excellent source for general lighting, down lighting, architectural and street lighting applications. The unparalleled thermal resistance of 0.7° C/W allows the extreme power density from such a small light source to create a compact and efficient optical system. LedEngin 40W LED light source exceeds the luminance of competing LED solutions by 6-10 times solving a major challenge of working with larger LED sources in flood and spot lighting applications. The high quality materials and the patented packaging technologies are chosen to optimize light output and minimize stresses resulting in superior reliability, color point stability and lumen maintenance well beyond industry standards. The robust packaging allows the 40W LED to meet JEDEC Level 1 Moisture Sensitivity Levels for unlimited product floor life.

LedEngin also offers 24° and 35° lenses specifically optimized for this LED delivering the highest quality and quantity of light within the beam. The secondary optic maximizes usable light and provides a smooth light gradient with uniform color across the beam. There are no hot spots, shadows, rings or fringe effects that other lighting solutions, including other LED sources, exhibit. By utilizing these patented lenses, the LedEngin emitter/ lens combination performs exceptionally without additional filters or diffusers to create the highest quality lighting solution available today.

The real importance is that we can actually offer our customers

These heat sinks, which are offered with different diameters and contours, are available in different sections of different lengths to suit specific heat dissipation applications.The LEDs are fastened onto the heat sink using thermally conductive, double sided adhesive tape, 2-component thermally conductive adhesive or screws. In the standard version, the surface is black anodised or of natural colour.

‘LEDs are a fascinating new technology,’ said Michael P. Simonis, president, Unilux, ‘but they are not for every printing or labeling application. Their softer light makes them best suited for inspecting labels and packaging with highly reflective coatings, foils or metalized substrates or on high-speed lines. Pulsed LED lights can replace strobe lights with Xenon lamps, where inspectors sometimes need to dial down the intensity or use frosted glass to avoid harsh reflections. When combining the light with our unique reflector designs, Unilux can provide even illumination across the entire surface.’The Unilux LED family of inspection lights carries a higher initial cost than the strobe lights with Xenon lamps, but the LED lamps do not have the same replacement costs.

‘The selection of pulsed LED or stroboscopic inspection lighting really comes down to the application,’ Simonis said. ‘The pulsed LED is better for high-speed, highly reflective printing, and the strobe for most other printing applications. LEDs can have a better light output than Xenon lamps when you have a flash rate greater than 15,000 flashes per second. The costs are about the same over a 3-5 year operating period, with the cost savings on the LED units being better after that. The real importance is that we can actually offer our customers the best lighting solution to meet their exact needs. It is not about developing an LED light or a Xenon lamp; it’s about being able to guide the customer to which light is best for them and to help produce the best final product. Only Unilux can do both.’

The company executives said that the company had begun supplying LED

The company executives said that the company had begun supplying LED backlights for notebooks since last quarter. And they project six to eight out of 10 Notebooks to use LED backlights sometime in the second half this year.The company’s LED production ran close to 80% capacity last quarter, accounting for 10% of the company’s total revenue. The company depends on cold cathode fluorescent lamps (CCFL) as major revenue source.Wellypower’s Taiwanese peers, including Light House Technology Corp. and Sintronic Technology Inc., also plan to boost output capacity this year. According to Light House executives, the company had begun supplying LED backlights for Notebooks and big LCD screens.Sintronic plans to expand its output capacity of SMD LED packages this quarter to 50 million units, parts of which to be for light bars and lighting fixtures.

LightTools 6.3, the newest release of the illumination design and analysis software from Optical Research Associates (ORA), delivers an expanded, more powerful tool set for optical system modeling and optimization. The software now features an Alternate Optimization Engine, which supplements the existing optimizer and enables users to successfully address an even broader range of design problems. In addition, LightTools 6.3 permits optimization with user-defined variables, merit functions and constraints, utilizing either of the optimization engines, to further expand the classes of systems for which the software can converge on an efficient solution.

 LightTools 6.3 also adds important new functionality for LED modeling and simulation. An expanded LED library has been incorporated that contains mechanical models for hundreds of LEDs from all major manufacturers, including apodization files that allow accurate far-field modeling of source output, as well as ray data files for both near-field and far-field output. Furthermore, LightTools ray data files now include color information to model the spatial and angular output characteristics of the source as a function of color.

LED supplies are much tighter than LCD supplies since its applications in cell phones

A unique feature of austriamicrosystems’ AS1115 is the built-in LED error detection. Simple and intuitive to use, the user-friendly software interface allows the error diagnostics to be easily accessed during normal operation. This solution can detect any open- or short-circuit within the multiplexed 8x8 LED array, and a detailed error report can be read out with the exact position of the broken LED, this is especially helpful to reduce test time during production.The company scored a total sale of NT$964 million (US$29.426 million) for the second quarter, with quarterly growth rate reaching 84%, the highest among its peers on the island. The company indicated that orders for LED backlights and LED lighting have fueled the growth recently.
The company has been engaged in manufacturing and developing of LED backlights for years and effectively carving out niches from this year. In light of growing concerns about environmental protection globally, Unity Opto has stepped up developing a variety of LED backlights for display panels used in handsets and notebook PCs, which have helped to drive up shipments by over 50% in the second quarter.Unity Opto’s LED lighting products, with enhanced brightness and improved color temperature, has been well-recognized by major international buyers recently. The company projects sales of the product line to triple this year from last year.
Unity Opto is also optimistic about the third quarter outlook, believing that the popularity of Netbooks and emergence of CULV (consumer ultra low voltage) platform-based laptop will further drive up demand for LED backlights in the second half of 2009. The company’s procurement list includes items like LED chips, LED backlights, display panels, monitors and TVs. And the estimated value of the procurements increases by 7-10% from 2008.LCD panel supplies are reportedly running short, and Samsung Taiwan’s executives said that LED supplies are much tighter than LCD supplies since its applications in cell phones and TVs as backlights have sharply increased.

It is the icing on the cake on this design

Willie Williams, U2 show designer, says “Video is the most powerful tool you can have on stage. But now that video is so ubiquitous in rock stage setting, we needed a very extreme change of canvas to be heard. The transformable LED gave us the chance to create a transparent 360° moving video element, unprecedented in this industry. It is the icing on the cake on this design.”

“It is thrilling to see the work I have been doing with transformable structures expressed in such a whole new way,” Chuck Hoberman adds. “The screen is like a living thing, it continuously changes shapes and forms and the video acts like live skin on it. It is one of the most fascinating objects in the world now.”

“We wanted to create something that was bigger than a conventional stage. This tour was big enough to make a purpose built structure,” says Mark Fisher, U2 stage designer. I wanted to create a transparent stage and really needed a video screen that would fit in that environment, a round screen that would not block the view for the audience. Barco's FLX gave us the chance to create this. We were happy to be working with Barco again; they have helped very well in the past and delivered an extraordinary product for this show.”

Frederic Opsomer, Vice President of Barco's Innovative Designs, adds “There have been many evolutions in the LED video market for concert touring, from a fixed IMAG screen to moving screens to transformable screens now. This is the fifth time I have been working with U2 and it is again a big honor to be part of it. The entertainment business is constantly asking for new and innovating products, even in these difficult times and the U2 360° tour is a perfect example of this.

will mainly be used in general lighting applications

Founded in 2005, Lagotek Corporation develops residential and commercial building automation systems based upon patent pending, and company-owned intellectual property. Applications for this technology include audio, climate control, security systems, intercom systems, lighting, video monitoring, window coverings, IR control, and irrigation systems.In addition to manufacturing LED StandAlone and controlLED (dimmable) lighting products to replace fluorescent lamps, Advanced Control Technologies, Inc. (ACT) designs and manufactures powerline carrier products to control lighting and other electrical loads which include programmable transmitters, coupler/amplifiers (for multiple phase power) and receivers. ACT also designs and manufactures a family of Z-Wave home and office automation products that use radio frequency signals to control lighting and other electrical loads.

With the fast growth in LED outdoor displays and backlights, DisplaySearch forecasts that display LEDs, including 24 billion for active outdoor display and 34 billion for LCD backlights, will have a 34.7% share of the global 167 billion unit LED market in 2012, making display LEDs the largest market segment. Low-current LEDs will be the mainstream type used in large-area LCD backlights, due to cost, thermal management and luminance efficiency requirements. High-power LEDs, with a driving current higher than 350 mA (more than 1W), are not well-suited for LCD backlights due to thermal issues, and will mainly be used in general lighting applications that require high brightness.

 The penetration rate of LED backlights in notebook PCs will reach 52% in 2009, and DisplaySearch forecasts penetration will grow rapidly to 81% in 2010. In LCD TV, the penetration rate will ramp up from 3% with 3.6 million units in 2009 to 10% with 15 million units in 2010. Leading LCD TV brands including Samsung, Philips, Sharp, Sony, Toshiba, Vizio and LG are planning increased use of LED backlights starting in the second half of 2009. A driving factor is the change in LED backlight structure from direct to edge light type, which reduces the cost premium over CCFL backlights. Finally, LED backlights in desktop monitors are expected to reach 31 million units in 2012.

the product in the fourth quarter of this year

Optimistic about industrial prosperity in the second half of this year through next year, Yeh stressed that demand from notebook PC, TV and lighting sectors has infused strong growth momentum into the LED industry. Increasing popularity of LED-backlit LCD (liquid crystal display) TVs will also serve as major driving force, he added.At the show, Everlight unveiled its newest AC LED, which can work without transformers and last for 50,000 hours. The company is scheduled to start shipping the product in the fourth quarter of this year.

The company had raised $10.5 million in March in its first round of funding, and is expecting an additional $20 million early in the summer, according to CEO Matt Thomas. The product is expected to reach full production in September.The company hasn’t disclosed details of its technology. But it essentially uses optics with a different shape that more efficiently extracts light out of the chip, Thomas said. “We think of [it] as an optical light-emitting device, as opposed to a semiconductor process that happens to create light,” he said. “We truly have some breakthrough physics.The chip structure extracts more lumens and reduces the internal refraction, delivering more watts in a smaller package, using conventional manufacturing methods, the company claims. Illumitex has reached more than 100 lumens per watt already, expects to reach 150 lumens per watt by the end of the year — which would make the lights 50 percent more efficient than other LEDs — and wants to hit 250 lumens per watt by the end of next year, Thomas says. That last goal would put it 15 years ahead of a U.S. Department of Energy target of the technology reaching 160 lumens per watt by 2025.

Illumitex’s LEDs also produce more uniform light than other LEDs, according to the company. And the light all comes out of the top of the device in one direction, which means the lights don’t need reflectors. This simplicity makes the lighting package smaller, a plus for manufacturers looking to make thinner devices. Additionally, as Illumitex delivers three times the usable light, manufacturers also can use fewer LEDs, making the footprint smaller still. Altogether, the LEDs get 10 times the light out of the same sized package, said the company.
