LED design engineers in building high Color

This new RGB SPNovaLED offers a long lifetime due to its silicone encapsulation and low thermal resistance of the housing. The dimensions are equal to the other SPNova LEDs, while the viewing angle was designed to 125° to ensure superior color mixing among the colors.The new RGB SPNova LED is suitable for a variety of applications such as full color display board, signage, decorative lighting, channel light and architecture lighting, outperforming similar competition devices in almost every significant area.Future Lighting Solutions today announced new capabilities to support LED design engineers in building high Color Rendering Index (CRI) tunable white applications that are optimized for light output and efficacy. The company has developed patent-pending intellectual property, now available for customer licensing, that provides the knowledge, tools and technologies to optimally select three or more LEDs, as well as their respective drive current and dimming ratios, to meet high CRI design specifications.

For example, the company can demonstrate at the lighting system level how to tune the color temperature from 2800K to 4800K while maintaining a CRI of 90 and above. Several general lighting, medical lighting, and retail display lighting customers are currently taking advantage of these capabilities to develop new high CRI applications.Future Lighting Solutions has already used its proprietary platform to develop several prototype systems leveraging the latest LED drivers, microcontrollers and color mixing optics. The company has also invested significant engineering resources to minimize the implementation cost, time and required PCB board space.

These efforts are now being extended with the development of innovative solutions for tuning and maintaining the target color temperatures by leveraging powerline communication, wireless, and sensing (capacitive, ambient light, temperature, proximity, motion detection) technologies.The test report indicates that the total lighting lumen of Apollo series 180W LED streetlight is 9800lm with power factor 0.97, which makes this product one of the most efficient LED street lighting systems in the world.

motion sequences by comparing two consecutive frames

All FX5 sets come with NuVision's own FX5 and FFM technologies. FX5 eliminates the need for the 3:2 pull down algorithm found in 60Hz displays, by recreating each frame five times, thus utilizing the 120Hz and high refresh rate of the panels. Many other LCD manufactures deploy black-frame insertion or simply attempt to double the frames in an attempt to achieve 120Hz. This works adequately when a motion sequence moves from left to right on the screen, but if it is reversed, the display reverts to its original 60Hz picture.FFM is instrumental in creating clear, flicker-free fast sports and motion sequences by comparing two consecutive frames and generating additional interpolated frames. And for an additional benefit, NuVision makes it easy to shut both functions off completely to control any latency issues that may occur.The new Lucidium FX5LS Series comes complete with a full, two-year manufacturer's warranty on all parts and labor.

The PEAK LED-UV technology from AMS represents a revolutionary step forward in the graphic arts industry and the UV curing arena. As a 100% solid-state device, there are no moving parts to maintain in the LED UV module, no heat is emitted from the light source, and at a 20,000+ hour estimated life of the light-emitting diodes, and the system potentially never requires a lamp change.

The PEAK LED-UV architecture is available in an ultra-compact, 3.5-inch (8.9 cm) square module format that produces an intense, uniform band of pure UV along an arc that scales from 3 inches (8 cm) to over 80 inches (2 m) wide. The system, which takes advantage of a patent-pending optical, thermal and interconnect design, will be offered in a package format that simplifies operation, allows interchangeability of modules on a machine and greatly eases integration with current and future machine designs.

The announcement follows the completion of a ￡140,000 trial contract of Marl Sci-Light technology, arranged by distributor EAO, in which a 3-car Class 323 unit was equipped with the electronically controlled lights as well as data monitoring equipment to enable performance and energy consumption to be evaluated in detail.Marl Sci-Light technology takes advantage of the controllability of LED lighting technology to adjust and supplement carriage lighting as ambient lighting conditions change. A 17W Sci-Light fitting replaces a 36W or 40W tube.

our customers can quickly and easily change their message

Utilizing its proprietary Ultra Low Distortion Solid State Power Supply technology, the fixtures to be developed over the next 11 months will replace inefficient incandescent fixtures. Beyond efficiency, life, and maintenance specifications, the fixtures must meet the Navy's new stringent requirements for LED systems which include light output, shock and vibration, corrosion, EMC and EMI compliance. "The SSL lights developed under this grant will save a significant amount of energy and maintenance. As an example, using only 26 watts, a new LED fixture saves 76% (or 84W) over the incandescent fixture it replaces. In addition, we fully expect that bulb replacement will become a thing of the past with the LEDs' projected lifetime of up to 50,000 hours or more," commented Roger Buelow, Energy Focus CTO.

Porlier Outdoor Advertising Co., located in the western suburbs of St. Louis, Mo., has installed two digital billboards manufactured by Watchfire Digital Outdoor. The 19mm 14’x48’ billboards are located in heavily traveled, highly visible locations in St. Charles County, a bedroom community of St. Louis.Since the digital billboards went live, Porlier Outdoor has stuck to a very specific sales strategy that differs from how they sell their vinyl billboards. “We see digital billboards as a direct replacement for television, radio and print advertisements,” said Brent Porlier, president of Porlier Outdoor. “With digital billboards, our customers can quickly and easily change their message, the boards are attention-grabbing, and unlike other mediums, the audience can’t change the channel or turn the page.”

Watchfire Digital Outdoor produces the industry’s only 19mm pixel pitch billboard—which packs 768 LEDs into every sq. ft.—and is capable of producing 281 trillion colors. It fully encapsulates the LED module in a thick bed of silicone gel, which enables the LED boards to operate in extreme weather conditions: 180+ days completely submerged in water, 60 days in a salt-spray chamber, and temperatures ranging from -40° F to 120° F. In areas where heat and humidity are both high, the silicone gel encapsulation protects the boards from humidity and moisture, greatly improving projected reliability.The PAR20 LED bulbs are engineered to last 50,000 hours. The bulbs are also environmentally responsible as they consume less energy than standard bulbs, and are lead free and contain no mercury. These lights generate very little heat and emit no UV rays which make them an ideal choice for the museum and retail industry. These lights are also perfect for store fronts and point of purchase displays which are typically illuminated for long hours.

reduce labor costs associated with bulb replacement

Performance LED bulbs contain high-powered solid state LEDs (Light Emitting Diodes) that are harnessed with ocular lenses to produce bright directional light output suitable for both distance and close-range uses in general lighting applications. They are true replacements for their halogen and incandescent counterparts based on the light output they offer, but they last up to 30,000 hours and use up to 90% less energy. They save money, increase convenience and, where applicable, reduce labor costs associated with bulb replacement.

Additional benefits of Performance LED light bulbs include resistance to shock and vibration (no filament), no mercury (no special disposal requirements), no UV emissions (no color fading of artwork or attracting of insects) and no warm up time for illumination or full brightness.

Under increasing demands for LED backlights for LCD TV and notebook computers, the board of directors at Epistar Corp. recently approved to issue 110-135 million units of global depository receipt (GDR) to raise some NT$10 billion (US$303 million at US$1:NT$33) to build up inventories of materials for the blooming market, according to Taiwan Economic News. Some industry watchers believe Epistar would use the GDR offering to attract foreign shareholders. Epistar will set the issuance date and price in two weeks, according to the report.

the typical metal halide fixture they replace

As part of a Phase II energy conservation and sustainability project underway throughout campus, ASU's partner APS Energy Services replaced over 2,000, 150 W metal halide fixtures with Lighting Science's 78 W LED low bay luminaires. By replacing existing metal halide fixtures and lamps, ASU will reduce its energy consumption by 1.5 million kW hours, which is equivalent to the annual greenhouse gas emissions from 208 passenger vehicles.

Lighting Science's pyramid-shaped LED fixtures are made up of 108 light sources, whereby if one light source dims or fails, other light sources remain to provide a reliable level of illumination. The new fixtures are also less costly to maintain because they last 50,000 hours, or approximately three times longer than the typical metal halide fixture they replace.

“Momentum is building on this exciting new product line, and with the launch of our much anticipated 25 degree lens offering – we are now able to address applications needing a more direct focus of light; including spot lighting of merchandise for retail stores, track lighting, and numerous other spot / accent lighting applications,” stated Mike Bauer, President & CEO of Nexxus Lighting.

There are useful similarities in the underlying design

There are useful similarities in the underlying design and manufacturing technology for quantum dot solar cells and other printed electronics applications such as batteries, sensors, conductors, lighting, logic and memory," he said.

Squires noted LED/OLED displays will likely emerge as the second most significant market for printed electronics.

"When you can leverage a single enabling technology, such as our semiconductor quantum dots, to enter two or more different, but massive, markets without straying from your core competencies, the business opportunity is very compelling," he said.

Squires said there is a frenzied pace of amazing discoveries in light-related applications. However, it was clear new work would be limited in commercial application by raw material costs. Access to high quality, affordable quantum dots emerged as the key ingredient for a number of these exciting developments. When coupled with high-throughput, inexpensive manufacturing such as screen printing, we believe wide market penetration is inevitable.

The University of Arizona pioneering technology makes significant improvements over prior art. Organic LED / OLED based displays now have the potential to be manufactured using very high volume, low cost roll-to-roll print processing on inexpensive substrates.

In addition to the potential to deliver a significantly lower price point, this technology can also provide, higher definition, increased viewing angles, lower power consumption and reduced response time for an enhanced picture, all in a very thin, light weight, format. These characteristics enable display technologies to flourish in environments that have previously been uneconomical or simply not viable.

small retailers who are committed to reducing the energy costs

The hysteretic control function of the HV9918 maintains a constant output current to the LED string at all times, regardless of input voltage fluctuations. LEDs are proven to be far more reliable and long lasting when driven by a constant current than by a direct voltage source. It drives loads of up to 1.0A at over 90% efficiency with +/-5% current accuracy from input voltages of 4.5 to 40V. The IC also features an embedded FET for cost and parts count reduction in solid-state lighting applications.

“Supertex’s HV9918 provides fast transient load response and eliminates the need for feedback-loop compensation,” states Ahmed Masood, Vice President of Marketing for Supertex. “With its built-in switching FET, this device reduces overall system cost and board space while delivering accurate current control for LED lighting applications.”

The Wal-Mart Superstore, the first retail store to feature light-emitting diode (LED) parking lot site lighting, based on specifications developed by the U.S. Department of Energy's (DOE's) Retailer Energy Alliance, will reopen on July 15, 2009, in Leavenworth, Kansas. The Superstore will serve as a test site to determine the viability of expanding LED parking lot lights at Wal-Mart stores nationwide.

Wal-Mart is one of 43 retailers that are actively engaged in DOE's Net-Zero Commercial Building Initiative (CBI) as members of the DOE Retailer Energy Alliance (REA). REA members work with DOE and the national laboratories to advance the development and market adoption of net-zero energy commercial buildings. The alliance has attracted large and small retailers who are committed to reducing the energy costs, greenhouse gas emissions, and overall operating risks of retail businesses. The primary aim of DOE's energy alliances is to create specifications for promising energy efficiency technologies, test their viability in order to encourage use, and drive down costs.

the lack of environmentally friendly lighting options in decorative applications like chandeliers

Our newest high density, high flux LED offers the brightest 40W light source with the highest light output and highest flux density for architectural and general lighting applications,“ said Dr. Xiantao Yan, Founder and Chief Technical Officer, LedEngin, Inc. “With record low thermal resistance, and thermally and electrically isolated pads, this package is ideal for downlighting fixtures and retro-fit lamps. By utilizing specially optimized lenses our 40W products continue to deliver the maximum “Lux on Target”, or usable light, that LedEngin products are known for.”

Yaham is a California-based solid-state lighting company specializing in ultra-bright, ultra-compact LEDs capable of emitting 2,000+ lumens, delivering extreme flux density and industry leading reliability. The family of LED replacement lamps and lighting modules provides superior quality light in directional applications equivalent to 35W and 50W halogen lamps. LedEngin also develops LED custom solutions and provides expert application support on optical, electrical and thermal management.

Americans are frustrated at the lack of environmentally friendly lighting options in decorative applications like chandeliers, sconces or decorative lamps. Going “green” usually means replacing an incandescent bulb with a compact fluorescent (CFL) and sacrificing the good look that high-end fixtures give with incandescents.YAHAM has introduced the world’s first liquid-cooled LED light bulb, the HydraLux-4, that gives true 360 degree light to finally allow consumers to maintain that “high-end” look, while getting the superior energy efficiency of LEDs. The Eternaleds Hydralux-4 consumes 4W to provide the light equivalent of 25W incandescents with a lifetime of 35,000 hours.

visible lighting applications that require concentrated, high-intensity light

Unilux products are built around stroboscopic surface inspection lighting that enables operators to spot defects at full production speeds, which can exceed 750 meters per minute (2,200 feet per minute). Operators can use their knowledge of products and production systems to determine the severity of the defect and take steps to find and eliminate its cause. The company has combined its high-speed inspection lighting with high-speed video and photography systems to provide engineering departments with visual data to develop long-term solutions to repetitive production problems.


Lumex announces the global launch of their QuasarBrite Narrow Beam SMT LEDs providing users with a tight beam of high-intensity red, green or blue light. Compared to traditional SMT LEDs, these Narrow Beam SMT LEDs allow for a 93% reduction in beam angle, making the technology ideal for medical device, security, sensor and visible lighting applications that require concentrated, high-intensity light.

"Despite their many advantages, SMT LEDs traditionally could not provide a narrow beam of light without the use of external optics," explained Jeff Oliveros, Director of Engineering, at Lumex. "Thanks to QuasarBrite Narrow Beam SMT LEDs, this is no longer the case. Whereas traditional SMT LEDs offered a light beam of ±45 to ±85 degrees, QuasarBrite Narrow Beam SMT LEDs provide a light beam of ±6 to ±10 degrees ? up to a93% reduction in beam angle."

With QuasarBrite Narrow Beam SMT LEDs, the LED is mounted upside down and shines directly into an internal parabolic reflector providing high-intensity brightness in a narrow beam of light without the need for external optics. As such, QuasarBrite Narrow Beam SMT LEDs can provide a 50% cost savings and 50% real estate savings when compared to traditional SMT LEDs that rely on external optics to achieve a tight beam of light. The elimination of the need for external optics also significantly simplifies manufacturing processes, resulting in additional cost savings.

the ability to perform colorimetric analyses of spatial

Another significant feature in LightTools 6.3 is an enhanced thin film modeling utility. This allows the user to enter a thin film coating and then simulate the performance of that coating on any substrate and under any conditions of use. Other new features include an IES file format import utility that reads and converts IES formatted angular intensity data files into LightTools angular apodization files, and the ability to perform colorimetric analyses of spatial and angular luminance calculations.

In the workshop “Indoor and Outdoor Lighting” OSRAM OS will demonstrate a street lighting solution designed of light fixture based on OSRAMS outstanding High Power LEDs.

light output in a smaller space and a wider spread of light

The company executives noted that LED-backlit LCD TVs are focused for their slim design, energy efficiency, and eco-friendliness.The RXD2 is based on an innovative multi-chip LED light source. Unlike conventional high-output LEDs, this technology incorporates multiple LEDs in a single package, giving increased light output in a smaller space and a wider spread of light.

Effective thermal management is provided by proven pure-water heat-pipe cooling technology, which transfers heat away from the back of the LED source to the cooling fins. This advanced method eliminates the need for large, heavy heat sinks and helps the RXD2 to achieve a maintenance-free life of 50,000 hours.Available with 1-10V dimming as a standard option, the downlight comes in round and square versions and can be specified as trimless or with white, silver or chrome bezels. It also offers a choice of 2900K warm white or 5000K cool white illumination, with efficacy values of 54 or 59 lumens per circuit watt, respectively.

The Axent RXD2 is a compact and lightweight fitting, and its body height of only 86mm makes it particularly suitable for use in restricted ceiling voids.The investment, mainly for encouraging environment-related industries and technologies such as renewable energy, LEDs (light-emitting diodes), smart power grids and hybrid cars, is expected to create up to 1.81 million jobs, the government said.The investment is a move in the right direction as it signals the government's intention to boost its competitiveness by leading in the greentech sector," said Yong-Jin Kim, Head of Global Business Group at Daishin Investment Trust Management.Korea could be a niche player in the global greentech market as it promotes its LEDs and other manufacturing industries such as the auto industry with the focus on doing research to make production processes environmentally friendly.

When connecting to an ambient light sensor

LED lighting products for commercial and industrial facilities that improve energy savings, reduce maintenance costs, and are safe and easy to install. Based on advanced electro-optic technologies, Albeo's reliable light fixtures provide superior performance at lower costs than competing technologies. Albeo's management team has decades of experience in solid-state product development and manufacturing, and continues to deliver new products that enable users to better control their total operating costs.combined with an ultra-thin prismatic supercapacitor, delivers an ideal LED flash and power management solution for slim camera phones and digital cameras," said Marie-Therese Capron, ON Semiconductor director of low voltage power management products. "This total LED flash solution supplies comparable light energy to xenon flash, but with only half of the comparable solution height and no need for an extra LED for video capture. The NCP5680 enables the Li-ion battery to support more power-hungry functions for a longer time.

NCP5680 complements the Li-ion battery by supplying high-peak-current of up to 10A for flash lighting optimized for use with the BriteFlash Power Architecture developed by CAP-XX. Fully programmable control of charging and discharging of the supercapacitor and unique overload protection ensure the right amount of light is provided for high-quality photography. The integrated driver can also power other high-peak-current circuits in portable systems, such as audio amplifiers, extending the useful battery operating time.To produce high-resolution pictures in low-light conditions, cameras of 5Mpixels or more require a high-intensity flash. Today's white LEDs can deliver this level of light energy, but require up to 400 percent more power than a camera battery can provide. To support the battery, the NCP5680 manages a supercapacitor to drive the LED flash to full intensity, supplying high-peak-current up to 10A. The integrated driver in the NCP5680 also manages the supercapacitor to handle other peak-power needs: zoom, auto-focus, audio, video, wireless transmissions, GPS readings and RF amplification.

The NCP5680 integrates all circuitry required to charge the supercapacitor, manage in-rush current and control LED current, thus saving designers development time, board space and component cost. Fully programmable control of charging and discharging of the supercapacitor ensures the right amount of light for high-quality photography.The I2C registers in the NCP5680 allow users to adjust the output current and flash duration of each of the two LEDs in real time. Hence, this solution can perform different lighting effects such as indicator light, pre-flash, and power flashlight for photographing and torchlight for video recording. When connecting to an ambient light sensor, the NCP5680 will automatically limit the flash duration to prevent photo over-exposure, thus preserving the photo quality. Additionally, the supercapacitor charging current is adjustable through an I2C register. NCP5680 can disable the charging operation during global system for mobile (GSM) transmission to limit the current drawn from the battery.

For outdoor pole-mounted area and roadway luminaires, application requirements are a minimum light output from the luminaire of 1,000 lumens (initial), and a minimum FTE that varies according to whether the luminaires are shielded or unshielded, high output or low.Luminaire types in this application include but are not limited to luminaires intended for lighting streets, parking lots, walkways, and plazas, and also decorative post-top luminaires. This category excludes luminaires intended to be mounted below eye level, e.g., bollards and steplights.Through the COB (Chip On Board) manufacturing process, low power multi chips are placed directly on aluminum board and packaged with a light guide structure and diffuser that may generate 20~30% more light output than other COB packaging. Compared with multi high power LED, iLEDm’s LEM product presents an even lighting and creates no stack image. The patent of the current design has been applied for in Taiwan, China, Japan, America and Europe.

Another advantage for iLEDm’s LEM is its heat dissipation. By using multi low power chips on aluminum board, heat spreads evenly across the surface of the board instead of using high power chips. Heat solution may also be solved more easily by using iLEDm’s product.LEDm Photoelectronics Inc is aim to be the best lighting source provider in LED lighting industry. iLEDm provides LEM in long, square and round shapes. Designers may also apply them into different lighting fixtures. For example, desk lamp, light bulb, tunnel lights, ceiling lights, panel lights etc. Other than the standard products mentioned, iLEDm also accepts orders for customerized design which may help improve and develop new lighting fixture.

Eyeing the growing LED needs for their panels

Eyeing the growing LED needs for their panels, nearly all panel makers are participating in the LED business through new LED companies or investments in existing manufacturers. DisplaySearch analysis indicates that Nichia and Toyota Gosei will continue to dominate the market for blue and white LEDs for LCD backlights over the next three years, due to their strong patent portfolios and customer relationships. However, Samsung LED, Stanley, Citizen, Showa Denko, Seoul Semiconductor and OSRAM are targeting growth in LED backlights for LCD TVs. Finally, Taiwanese makers like Lite-On, Chi-Mei Lighting, Lighthouse and Everlight are entering the backlight market with low cost structures.

The DisplaySearch Display LEDs: Lighting Up the Display World report also reveals that LED revenues for outdoor displays will reach $1 billion in 2009 and are expected to grow to $1.5 billion in 2012. The use of LED outdoor displays in the 2008 Beijing Olympics provided international visibility, and such events will be a driving force for growth in LED outdoor displays in the coming years.

"LEDs will create new growth for the TFT LCD industry due to characteristics such as lowering power consumption, meeting green requirements, adding dimming capability, improving color performance and enabling slim and light form factors for LCD panels and applications," noted Yoshio Tamura, Vice President of DisplaySearch and the component research team leader. "On the other hand, TFT LCDs also provide new vigor to the LED industry, as they open up broader applications requiring higher quality and more advanced technology."

The company is aiming at three primary markets

The company is aiming at three primary markets: mobile displays, televisions and general lighting. Though still facing some challenges ahead, it will take some time to prove its advantages in the marketplace, said the company.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, Light Tools 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.Another significant feature in LightTools 6.3 is an enhanced thin film modeling utility. This allows the user to enter a thin film coating and then simulate the performance of that coating on any substrate and under any conditions of use. Other new features include an IES file format import utility that reads and converts IES formatted angular intensity data files into LightTools angular apodization files, and the ability to perform colorimetric analyses of spatial and angular luminance calculations.
