LUXEON power LEDs from Philips Lumileds are poised to rapidly increase their presence in front-of-vehicle applications with expected European Union regulations mandating daytime running lamps (DRLs) on new cars beginning in 2011.

One of the major factors driving LUXEON use will be the dramatic reduction in DRL power consumption (Watts), on the order of 80%, made possible by energy-efficient LED technology.

Audi and VW currently offer LUXEON-based daytime running lights, and several other carmakers are
preparing to release vehicles with LUXEON-based DRLs over 2008-09 as part of a movement to improve road safety by increasing vehicle visibility during daylight hours.


This energy savings is critical because DRLs built with conventional bulbs consume more power than any other exterior lighting application due to their always-on daylight use, potentially running afoul of today’s fuel economy standards.

A typical DRL solution with incandescent or halogen bulbs uses 40-80 Watts of power. LUXEON-based
DRLs consume 10 Watts of power or less because of the technology’s low power demands and energy
efficiency.

Given these benefits, any new regulation requiring DRLs is expected to drive broader LUXEON adoption for
daytime running lamps as well as other forward automotive lighting applications. Already, LUXEON
technology is lighting the world’s first all-LED headlight on the Audi R8 supercar.

“Today LED DRLs are used on fewer than 1% of vehicles, in part because daytime running lamps are not
required in most countries. If the new regulation by the United Nations Economic Commission for Europe moves ahead as expected, it will increase that number dramatically because of the low power usage,
longevity and design flexibility of LEDs compared to conventional light sources,” said Scott Kern, Vice
President, Automotive Sales, for Philips Lumileds. “LUXEON LEDs promise to lead the market because of
their reliability, high quality white light, and proven performance in the automotive industry.”

Over the years, Philips Lumileds has pioneered many automotive exterior lighting applications with its
LUXEON, SuperFlux and SnapLED products. In addition to driving the industry’s first all-LED daytime
running lamp and all-LED headlamp, the company’s solid-state lighting technology has enabled the world’s
first all-LED rear combination lamp, first single-LED stop-tail lamp, first LED front-, rear- and side-mirror
turn signals.

LUXEON^® Rebel Provides MORE LIGHT, LESS SPACE

The LUXEON Rebel gives you more light in a smaller package. According to Philips' website, the LUXEON Rebel provides more lumens per dollar, per package and per mm² than any other power LED available, LUXEON Rebel creates new design possibilities and challenges conventional thinking.

LUXEON Rebel is the smallest surface mountable power LED available today. With the industry's best lumens per package, highest light density (lumens per mm²), and the highest packing density, LUXEON Rebel is ideal for both space-constrained and conventional solid-state lighting applications.


FEATURES

• Lumen maintenance - 50,000 hours life at 700 mA with 70% lumen maintenance
• Moisture sensitivity level - JEDEC Level 1 unlimited floor life no need for reconditioning
• Lumen performance, > 80 lumens in cool white at 350mA
• High efficacy, flux density and lumens per package

Philips has developed a thin-film (TF) flip-chip to create a higher performance thin-film flip-chip (TFFC) LED. This technology is used in Philips Lumileds' line of Luxeon products. According to Philips, the TFFC LED offers better performance than the flip-chip structures and a higher light output and greater efficacies than vertical thin-film chips (VFC).

In 2007, Philips Lumileds released the LUXEON K2 warm and neutral white LEDs that offer new lighting possibilities

Warm-white and neutral-white LUXEON K2 emitters and a LUXEON K2 Star part  can be specified with any standard white emitter.

The new white colors have typical correlated color temperatures (CCT) of 3000K and 4100K and a color rendering index (CRI) of 80 and 75 respectively. The CCT range for LUXEON K2 now extends from 2670K to 10,000K and a new finer color bin structure allows for better overall selection.

Unlike most power LEDs that are limited to 700mA, LUXEON K2 warm white and neutral white LEDs can be run up to 1500mA and a junction temperature of 150°C. The new warm-white and neutral white can deliver more than 130lm and 140lm respectively. LUXEON K2 delivers more usable light at virtually any drive current and junction temperature condition.

“With the increases in light output performance and efficacy, there is expanding demand for power LEDs that deliver the quality of light required for general lighting applications,” said Steve Landau, Director of Marketing Communications. “Designers of residential applications, such as recessed can lights need uniformity, high color rendering and a warm white color temperature at 3000K. In many retail and commercial applications, a cooler temperature of 4100K is desired. With the new binning and phosphor technologies in LUXEON K2, the needs of lighting designers in both markets can be addressed.”

Lighting designers consider several critical “quality of light” factors when evaluating white LEDs: color temperature (CCT), color rendering (CRI) and color uniformity are three of the most important. The new LUXEON K2 parts address CCT and CRI and Philips Lumileds phosphor expertise and technologies ensure the highest degree of color uniformity resulting in white LEDs that are as much as 7 times more uniform that other white power LEDs.

LUXEON K2 Star, like the configuration already available in other LUXEON product families, consists of a white LUXEON K2 emitter mounted onto a metal core pc board (MCPCB). This configuration allows for rapid prototyping and production in a wide range of applications without the need to create custom level 2 boards. LUXEON Star products have been an industry standard for many years and been the configuration of choice for everything from architectural and entertainment lighting to emergency and portable lighting. Complete product information is available on the company’s website and in the LUXEON K2 datasheet also available online. LUXEON K2 warm-white and neutral-white power LEDs are in-stock and available for immediate delivery from Future Electronics. LUXEON K2 Star is stocked in limited quantities and interested parties should contact Future Electronics with their specific needs.

How intuitive graphical data sets help lighting designers accurately predict power LED reliability in different operating environments.

When designing LED-based lighting systems, engineers need to understand LED lumen maintenance and mortality in similar terms to those used when designing with conventional light sources. However, comparable data has been nearly impossible to find. In addition, designers need extra information to predict the lifetime of LEDs under a variety of operating conditions. A number of techniques to predict LED lifetimes have been proposed, but these have not been sufficient to generate the clear and unambiguous data that lighting engineers can use easily. This white paper provides lighting designers with an understanding of a new tool introduced by Philips Lumileds Lighting Company that simplifies the process allowing full flexibility in design options. This one tool provides designers with information that they need to make decisions about product lifetimes, driver constraints, number of LEDs required, and thermal management.

1. Aging and failure modes of lighting sources
2. Established lighting industry definitions of useful life
3. Established LED industry definitions: Lumen maintenance
4. Understanding LED operation and lifetimes
5. Completing the expression for lumen maintenance
6. Designing with B/L data for optimal lighting performance
7. Predicting LED lifetimes

Conclusion
The lighting industry needs LED manufacturers to provide data that is compatible with current design practice. However, this only answers a part of the challenge. LED vendors should also be in a position to provide more detailed information about product lifetimes under various operating conditions. This data allows lighting designers to deliver the best combination of purchase price, lighting performance, and cost of ownership for the life of the product.

From a user’s perspective, this data is most usefully expressed as a combination of B- and Llifetime as junction temperature and forward current are varied. This allows the system designer to make intelligent choices about the number of LEDs required, how they are driven, and the operating temperature.

Every power LED customer should therefore expect their supplier to provide this data as a matter of course, in any combination of B, L, Tj and If values, with clear definitions of failures (e.g. lumen maintenance below specified condition, electrical failures).

March 2008 -- LUXEON K2 with TFFC is one of the highest performance, most robust, and rugged LEDs available.  According to their sales literature, "They deliver industry leading light output, simpler and more efficient thermal management, and the ability to be driven at higher currents for longer periods of time than any other LED. Binned and tested at 1A, and with minimum flux bins of 160, 180 and 200 lumens, LUXEON K2 with TFFC LEDs are enabling never before possible lighting solutions."

It is Automotive Qualified, Autoclave Compliant, RoHS Compliant and Lead-Free.

This new LED's maximum operating range and performance is a power LED designed, tested and binned for operation at 1000 mA, offering minimum flux performance of 160 lm or more in addition to the following Industry-leading capabilities for a 1mm² chip device:

• Highest Drive Current: 1500 mA
• Industry Lowest Thermal
  Resistance: 5.5° C/W
• Highest Maximum Junction Temperature: 150° C for white
• Industry-leading lumen maintenance and reliability

The LUXEON K2 with TFFC can operate in real-world applications at drive currents of 1A and above. At its rated drive current, LUXEON K2 with TFFC operates at 66% of its maximum power rating and delivers unprecedented performance for a single Imm2 chip.

More than two dozen LED drivers available from Future Lighting Solutions are already capable of providing 1000 mA and even higher currents that will allow engineers to take advantage of LUXEON K2 with TFFC's high drive capability.

Application include security lighting, roadway lighting, automotive lighting architainment or spot lighting where maximum light and robustness are required while still delivering improved efficiency.  Cost effectiveness includes thermal management, drive electronics, optics and LED count. The ability for designers to increase current without increasing thermal management size or cost to the same degree ultimately results in a lower cost of light.

Incorporating TFFC technology and package improvements gives product managers the best LED for the most demanding applications and environments such as automotive, signaling, general lighting and architectural applications.  Using a single chip allows for the smallest optical source size -- making it easier to design optics such as reflectors, diffusers and lenses used in most applications.  LUXEON K2 with TFFC is also compatible with much of the complementary infrastructure for electronics, optics and thermal solutions already using LUXEON K2 LEDs.

Check Philips Lumileds Reliability Datasheets for graphical reliability and lumen maintenance tools. Philips Lumileds is building volume production of neutral-white and warm-white to be followed by royal blue, blue, cyan and green.

Philips Lumileds provides power LEDs for everyday lighting applications, and sets records for light output, efficacy and thermal management that are the result of ongoing commitments to advancing solid-state lighting technology and enabling lighting solutions that are more environmentally friendly, help reduce CO2 emissions and reduce the need for power plant expansion.

Lumileds' LUXEON LEDs are expanding applications in general lighting, automotive, digital imaging, display and signage markets.

In 2007 Cree and Raleigh, North Carolina, Launch Nation’s First “LED City” with Cost-Saving Municipal Lighting

Raleigh Recognizes Greater than 40 Percent Energy Savings as Municipal Garage Switches to LED Lighting.

Cree, Inc., a U.S.-based leader in LED solid-state lighting components, and the City of Raleigh, North Carolina, the anchor city in a rapidly growing metro area, developed a joint, city-wide initiative to test, deploy and promote LED technology focused on a variety of general lighting applications.

The “LED City” initiative will create a “living laboratory” to deliver the economic, environmental and usage benefits of LED lighting to the urban residents.

The first project is focused on validating both the cost savings and technology capabilities of LEDs through an installation of LED lighting in the City’s Municipal Building parking deck.

Both Cree and Raleigh public officials expect the initiative to serve as a model for other cities that are considering implementing energy-efficient infrastructures.

As part of the commitment to creating an “LED City,” Raleigh plans to deploy LED lighting, through its living-laboratory initiative, to serve a number of lighting applications over the next 18 months including:

• garage and parking lot lights
• street lights
• architectural and accent lighting
• portable lighting
• pedestrian and walkway lighting

Cree, the City of Raleigh and Lighting Science Group Corporation (OTCBB: LSGP) of Dallas, TX, also announced initial results of the first installation of the LED City initiative. LED-based lighting fixtures, provided by Lighting Science Group, were installed by Amtech Lighting Services in the Raleigh Municipal Building parking deck in December 2006. Progress Energy, Raleigh’s primary electric utility provider, says the floor equipped with LED lights uses over 40 percent less energy than the standard lighting system. Plus, according to Progress Energy’s research, the quality of light in the garage is greatly improved.

“The economic benefits for municipalities to invest in LEDs are clear – they

• save energy
• reduce environmental impact
  
• improve the quality of light

As leaders in one of America’s fastest growing cities, it’s our civic responsibility to invest in the future and ensure the highest possible quality of life and safety for our citizens in generations to come,” stated Charles Meeker, Raleigh mayor. “We believe that the cost savings and benefits of LED lighting are real and achievable today.”

“Today’s announcement represents a milestone toward large-scale adoption of clean, energy-efficient technologies,” commented Kateri Callahan, president of the Washington, D.C.-based Alliance to Save Energy (ASE).

“Raleigh’s progressive commitment to becoming the first ‘LED City’ will no doubt serve as a model for other cities seeking to improve energy consumption and reduce negative impacts on the environment. We commend Cree and the City of Raleigh for helping support our mission of achieving a healthier economy, a cleaner environment and greater energy security.”

“The City of Raleigh is willing to set the pace, and we invite other municipalities to join us in developing energy-efficient civic centers,” said Chuck Swoboda, Cree CEO and chairman. “This leading-edge effort establishes an important driver for LED adoption within the United States.”

LED City Initiative Yields Benefits Beyond Energy Efficiency

When Raleigh, N.C., the first LED City, and Cree, Inc. turned on new  LEDs in the municipal parking garage, people’s opinion of the quality of the lighting improved threefold.

Survey Shows Public Feels Safer in City Spaces Lit by LEDs

Raleigh exchanged the previous garage fixtures and their dull orange light for LED fixtures with bright white light, and people felt safer. The number of respondents who perceived the garage as “very safe” increased by 76 percent after the LED fixtures were installed, according to a survey by Mindwave Research of Austin, Texas.

Cree produces LEDs that provide a new source of energy-efficient light that can serve as the foundation for cost-effective lighting solutions. Lighting Science Group Corporation of Dallas, Texas, supplied the LED fixtures installed in the Raleigh garage.

“LED technology provides a clear benefit to municipal infrastructure, as well as to the citizens it serves,” said Charles Meeker, mayor of Raleigh. “This survey shows that LEDs can do more than improve light quality. In addition to the proven environmental and energy efficiency benefits the city has already documented, the survey shows that LEDs’ bright white light can help improve public feelings of safety in city spaces.”

The survey results showed that the parking garage generated a more positive reaction from most of the respondents after the addition of LED fixtures:

• Both men and women felt significantly safer post-installation: 74 percent rated the garage as feeling “very safe,” while only 2 percent did not feel safe. These figures contrast with the pre-installation numbers: Only 42 percent felt “very safe” with the original lighting, and 13 percent did not feel safe.
• The percentage of respondents who gave the garage an overall rating of “excellent” increased by 100 percent. The number of people who rated it as “poor” decreased from 8 to 1 percent.
• The lighting quality of the garage was “excellent” according to 86 percent of the respondents, a 258-percent increase from pre-installation respondents. The number of people who rated it as “poor” decreased from 18 to 2 percent.
• The cleanliness of the parking garage was perceived as “excellent” by 76 percent of the respondents, while only 58 percent rated it this way before the LEDs were installed, showing a 31-percent increase.

Raleigh agrees to become the nation’s first LED City.

The LED City initiative focuses on installing LED lighting, based on Cree’s energy-efficient LEDs, throughout the city to save energy and money and boost the quality of life for its residents by using the best lighting technology commercially available. As a result, the city has improved the energy savings and lighting of its municipal city parking facility, the first of a series of projects aimed at delivering the environmental and economic benefits of LED lighting throughout Raleigh’s “living laboratory.”

Research Note:
The two surveys of 200 people each were conducted on behalf of Cree, Inc. by Mindwave Research, Inc. The pre-installation survey was conducted November 11-13, 2006, and the post-installation survey was conducted February 5-8, 2007.

It's nice to see the "kid grow up", as my parents used to say.  I moved North Carolina in the late 1980s and was privy to the babysteps of the new regional innovator, Cree.  Simple name, complex technology...for a simple lighting solution.  It's hard to believe Cree is 20 years old...practical an emancipated adult!  And what a wake they have carved in their 20 years of youthful thinking and creative development.

Growing from six founders in 1987 to more than 2,600 employees worldwide today, Cree continues to work with silicon carbide and gallium nitride materials to lead innovation in the LED and lighting industries. Opportunities for Cree and the LED have never been better, driven largely by the world’s rapidly growing demand for energy efficiency and a cleaner environment.

“There is an ever-increasing global recognition that LEDs can be used in many lighting applications in place of today’s common light bulb to help solve the world’s energy and environmental challenges. Cree is in the unique position of being one of the few companies that has the technology to lead the LED lighting revolution, without the baggage of a traditional bulb business to slow us down,” comments Chuck Swoboda, Cree chairman and CEO.

“We have aggressively advanced LED technology for 20 years, with the last two years being particularly exciting, because we have achieved lighting-class performance for use in general illumination,” notes John Edmond, Cree co-founder and director of advanced optoelectronics.

“In the next several years, we can expect LEDs to become an increasingly important source of light in our cities, businesses and homes.”

According to the U.S. Department of Energy, over the next 20 years rapid adoption of LED lighting can potentially reduce the demand for electricity in lighting applications by up to 62 percent. It can also eliminate up to 258 million metric tons of carbon emissions and avoid the need to build 133 new power plants.

Cree’s innovations span a number of markets. In new products, Cree released the first commercially available LEDs that achieve a minimum luminous flux of 100 lumens, and the first warm-white XLamp® LEDs for use in indoor home and office applications. Cree has also actively encouraged cities to adopt energy-efficient LED lighting throughout their infrastructures. The cities of Raleigh, N.C., and Toronto, Canada, seeking to improve energy efficiency of public lighting, have been first to join Cree in the LED City™ program.

“Cree was founded on our conviction that wide-bandgap semiconductors, silicon carbide and gallium nitride, could be superior alternatives to silicon and gallium arsenide for a wide range of devices,” says John Palmour, Cree co-founder and executive vice president for advanced devices. “Our materials and device expertise are the result of intensive research and development for the Department of Defense and Department of Energy programs. Our work has led to commercially available products that today can replace inefficient light bulbs and even significantly reduce the power needs of today’s massive IT server farms.”

“It’s remarkable to see the semiconductor materials company we founded so many years ago evolve in capability to take on two of this generation’s greatest challenges: the world’s demand for energy and the need for products that have less impact on the environment,” comments Calvin Carter, Cree co-founder and director of advanced materials technology. “From LEDs to power and wireless devices, all Cree products can significantly reduce energy use and are environmentally friendly alternatives to less-advanced technologies. We are in a great position from which to continue our growth and industry leadership.”

In September, 2007, Cree announced it achieved R&D results of 129 lumens per watt for a cool-white LED and 99 lumens per watt for a warm-white LED.

These are the best results reported for packaged, high-power LEDs, and indicate that Cree is extending its lead in solid-state lighting through its continued investments in LED technology.

The results have been verified by the National Institute of Standards and Technology (NIST). NIST’s tests confirmed that the cool-white (5,813 K) LED produced 135.7 lumens of light output and achieved 129 lumens per watt efficacy. The warm-white (2,950 K) LED produced 104.2 lumens of light output and achieved 99 lumens per watt efficacy. The institute tests LEDs at 350 mA and measures the output after five minutes of operation to ensure thermal stabilization.

In coming years, such investments in core LED technology could lead to products that replace traditional light sources in all commercial applications.


“To replace traditional light sources, LEDs need to provide both high light output and high efficacy,” comments John Edmond, Cree co-founder and director of advanced optoelectronics. “Cree continues to push the limits of LED performance in order to realize the potential of the LED lighting revolution – energy-efficient, long-lasting LED light.”

International House of Pancakes (IHOP) franchise in Northern Virginia, owned and operated by Wilhelm Restaurant Group, Inc., has adopted Cree LED lighting products as the preferred lighting for all existing and future restaurants.

Since testing began in January, 2008:

* More than 100 retrofit LR6 six-inch LED downlights have been installed in two locations,
* Six additional locations have retrofit plans in progress, and
* Construction plans for a new IHOP have been modified to specify Cree LR6 LED downlights.

Paul Belle, vice president Wilhelm Restaurant Group, Inc., wanted to move away from conventional, incandescent lighting toward a more sustainable, energy-efficient light. He was considering compact fluorescent lights (CFLs) but changed his mind after seeing Cree’s LED products.

“Cree’s LED lights were much more impressive than CFLs,” said Belle. “LED light is more energy-efficient, generates less heat, has a longer life, and it’s just a better quality light, in my opinion.”

According to Belle, the IHOP employees prefer the LED lighting as it is very bright, easy on their eyes and enhances the general appearance of the food. “The light is not offensive like CFLs can be; the LEDs give off a warm, white light,” Belle said. “The best way I can describe it is to compare the light to a high-definition television. Everything under the LED lighting appears to have a better clarity, like HDTV versus standard definition.

 “It is normal to invest a little more in a new technology, but it’s worth it. Somebody has to be first and I’m glad to be on the cutting edge,” Belle said.

Cree’s LED lighting products use approximately 85 percent less energy and last up to 50 times longer than incandescent lights, and they use 50 percent less energy and last up to five times longer than CFLs. Previously, lighting products in the industry fell short in color quality, efficiency or longevity. Cree has created a dimmable LED lighting solution that leads the industry in a combination of all three critical elements.
