Recently in Architectural Signage with LEDs Category

OSRAM Opto Semiconductors has carried out pioneering work in the development of thin-film LEDs. Together with Dr. Andreas Bräuer of the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena, Dr. Klaus Streubel and Dr. Stefan Illek of OSRAM Opto Semiconductors have won the German Future Prize 2007, the technology and innovation award bestowed by the German President, for their joint development of LED-based illumination modules.

Now, thanks to new technologies for chip manufacturing, structural design (OSTAR) and beam shaping* the light output of the low-price, energy-saving LEDs has been vastly improved.

The new high-output LED modules are based on perfect synergy between solid-state physics and optics. The semiconductor components were built by OSRAM, while researchers in Jena took care of the optics.

OSRAM started developing thin-film LEDs in 1999.

The company took a major step forwards when it devised chip technology that permits the extraction of light in a single half sphere.

A novel platform for the thin-film LEDs ensures efficient temperature management and allows all colors of LEDs to be combined.

To use the light emitted by the LED chip as fully as possible, a special optic for the respective application is required and was accordingly designed and implemented by the Fraunhofer researchers. It consists of two parts: a primary and a secondary lens.

• The primary lens collects the light emitted by the LED close to the chip and combines it to form a beam.
  
• The secondary lens homogenizes the light beam.

Applications of LED Modules

• Battery-powered digital projectors.
  
• LED-based rear-projection TV
• Infrared LED light sources for pedestrian monitoring systems in cars,
• "OSTAR Lighting" LED module for general illumination.
  
• OSTAR modules will be made standard equipment in car headlamps as of 2008.

German President Horst Köhler presented the team of OSRAM and Fraunhofer researchers with the German research award, worth €250,000, in recognition of their achievement.

This technology was developed by scientists at OSRAM Opto Semiconductors with the support of optics specialists from the Fraunhofer Institute for Applied Optics and Precision Engineering IOF in Jena.

Efficiency Benefits Up to 82% in Energy Savings!

According to Flex Your Power, documented studies have proven the energy savings potential of LEDs:

	Replacing a red incandescent traffic signal head with a red LED unit cuts energy use by an estimated 82 to 93%. The use of LED traffic signals in cities can save 1 million kilowatt-hours (kWh) of energy and nearly $70,000 a year for every 100 signaled intersections replaced. The payback period is approximately two-and-a-half to three years through energy savings alone. There are 100 million exit signs in the United States containing incandescent lamps that consume a total of 20 billion kWh of electricity per year. LED lighting could save approximately three-quarters of this energy. By purchasing 1,000 exit signs for an initial investment of $30,000, a state government could save a net $455,562 over the products’ lifetime. The new signs would pay for themselves in six months. LEDs can replace neon, offering an 80% electricity efficiency improvement.

The benefits of LED lighting technology go far beyond reducing electricity consumption.

Even with a higher initial investment, dollar savings and quality improvements significantly outweigh costs.

LED technology's numerous benefits also include:
Long life and reduced maintenance cost High quality light output Increased safety as a result of LED's lower voltage Smaller, flexible light fixtures Increased durability (no filament to break) Lower lighting infrastructure load and cost for expansion

OSRAM Opto Semiconductors LEDs Illuminate the Golden "Dragon Fountain" in Olympic Park

Dragon-shaped water fountains in Olympic Park brightened by OSRAM Golden DRAGON LEDs

OSRAM Opto Semiconductors and Tong Fang joined hands to illuminate the elegant dragon-shaped water fountains in Beijing’s Olympic Park with OSRAM Golden DRAGON LEDs.

Tong Fang Co. Ltd. installed its dragon-shaped water fountains, located along the northeast side of the Bird’s Nest and the Water Cube in the Olympic Park, in July of this year.

The fountains were outfitted with OSRAM Golden DRAGON with lens and enhanced Thinfilm LED components, providing the “Dragon” with its characteristic golden glow.

The partnership marks OSRAM’s continued efforts to be the leader and top innovator in China’s LED market, as well as to provide support for China as it prepares to host the largest sporting event in the world.

Two impressive dragons team up

Tong Fang turned to OSRAM Opto Semiconductors for its leading-edge LED technology, but the partnership may have a deeper, if coincidental, Chinese connection as well: two dragons, OSRAM's Golden DRAGON LED lamps and Tong Fang's “dragon fountain”, working together to show strong support for Beijing’s Olympic Games.

Projects like the dragon-shaped fountains reflect the expanding opportunities customers find to create interesting and original LED solid-state lighting applications.

More than 600 meters long, the “Dragon” is formed by thousands of tiny water jets arranged in a long, gentle curve cutting through the Olympic Park, comprising a river stretching two kilometers long. The dynamic jets launch water columns as high as six meters, creating a kind of rolling wave, like the body of a dragon as it glides through the air. At the base of each column, mounted 10cm underwater, a lamp containing 24 OSRAM Golden DRAGON LEDs radiates yellow light upwards to a height of 15 meters, illuminating the “dragon” for four to five hours every evening.

Altogether 1,920 lamps containing 46,080 Golden DRAGON LEDs help bring the dragon fountain to life.

 “The first time Tong Fang discussed their idea for the dragon fountain with us, I knew OSRAM had to be involved, as it was a perfect opportunity for us to show the versatility, efficiency and advanced technology behind our Golden DRAGON LEDs. This kind of innovative and creative thinking is precisely how we aim to revolutionize the lighting industry in China and the rest of the world,” says Dr. Alfred Felder, CEO of OSRAM Opto Semiconductors Asia.

The OSRAM Golden DRAGON advantages
Tong Fang ultimately chose to work with OSRAM Opto Semiconductors because of the benefits inherent to using the Golden DRAGON with lens and enhanced OSRAM Thinfilm LED technology.

The Golden DRAGON  LEDs come with one of the narrowest viewing angle
integrated lenses in the industry (just 20°), taking up less space and reducing the need for secondary optics. Furthermore, the high optical efficiency (61lm/W) of these yellow LEDs enhances energy efficiency, while the over 50,000 hours lifespan (under proper operating conditions) minimizes maintenance costs.

 “We’ve already received extremely positive feedbacks from people who’ve witnessed the fountain in action, especially with respect to the golden color, which resonates with traditional Chinese perceptions of dragons, as they symbolize power, prosperity and celebration; and this summer is set to be one of the biggest celebrations ever,” says Miao Chen, General Manager at Tong Fang. “OSRAM, whom we’ve worked with before, has proven once again to be a highly reliable and forward-thinking partner in providing us with this solid-state lighting solution.”

OSRAM Opto Semiconductor’s golden future
Partnering with leading Chinese companies such as Tong Fang is a key ingredient to OSRAM Opto Semiconductors recipe for developing China’s rising LED market.  As a leader in its industry, OSRAM is continually aimed at shaping the future of lighting in China and developing people’s perceptions and understanding of LED technology, which has rapidly gone from niche market/high fashion to mainstream, mass market use, and the range of solid-state lighting applications expands day by day. By supporting local Chinese customers who wish to turn their next-generation lighting ideas into a reality, OSRAM Opto Semiconductor is confident that the China LED market will continue to flourish for years to come.

Despite a slumping economy, new store venue is seen as smart strategy by a lighting store in Fort Myers, FL.

The roughly $3 million building will offer a host of improvements over the current location, including a two-story atrium for grand chandelier displays, light lifts in the ceiling - a motorized apparatus that allows chandeliers to be lowered to eye level - and a customer service area separate from the showroom.

LED Signage Attracts Consumer Traffic

The exterior will be highlighted by a roughly 35-foot-tall electric sign with a 9-foot by 14-foot LED screen that can be used for advertisements and demonstrations.

In response to the downturn, the Bebbers have tightened their credit policies, reduced overhead through such things as cutting energy usage by using fluorescent display lighting and dramatically increased retail advertising. The additional advertising has meant a boost in retail trade over the past year, as has a moving sale that began in January.

Sector Marketing Strategy Shifts to Consumer Remodeling

"We felt a lot of people would keep their money and turn to remodeling and home improvements, so we started marketing to them to try and make up for the lack of the volume-builder business," Chuck Bebber said.

Today, retail customers represent about two-thirds of the store's business, a position commercial customers occupied before the advertising blitz.

SciWorks has new exhibit space focusing on the cranks, levers and lasers that are behind the basic science of physics.

In the new PhysicsWorks, displays are grouped by concept into mechanics, light and color, electricity, motion and perception.

The beginning of the exhibit starts with simple displays of levers, gears and pulleys, then moves on to flashier kiosks for electricity and lasers.  Sanford explains, "Not everybody is going to be a scientist, but everybody is going to have to deal with it at some point."

They include a room that captures a photo of your shadow on photosensitive material with an LED flashing light and a game that shows off the focused intensity of lasers.

There are also displays that are more like low-impact rides, such as a kid-size gyroscope, where you sit on a bicycle seat, and holding a spinning wheel by its axle, you turn around. That's the same concept used in the space and air industry to keep shuttles and planes straight, Sanford said.

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.

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.

A road-paving mistake was going to cost over $9,000 to cut the concrete, lay conduit and then repave it. The developer was desperate for other options to light a  6' x 9' Canyon Pines sign. A local solar contractor was able to provide a reliable, efficient and economical solution.

LEDtronics Inc. provided an efficient, largely hidden, and bright LED lighting solution. Mr. Bruce Howard, a LEDtronics representative from Howard Industrial Sales Inc., assisted Canyon Pines with  two  LEDtronics  LED Flood Lights.

These LED floodlights are designed to run on 12 volts DC with solar panels. This allowed lighting the sign without incurring costly landscaping and electrical power line costs. The LED floodlights provide cold white lighting (8,000K) using 5mm LEDs that remain cool enough to touch. These LEDs consume only 12 watts of power per floodlight compared to the power hungry 40 watt or 100 watt incandescent spot lights normally used in this application.

Now the whole system can be run on a 123 watt solar panel and a small battery bank. The solar cells charge the battery during the day, which in turn powers the LED floodlights at night.

The installation of this solar power LED lighting system only took two people one and a half days to complete. To extend the life of the system and operate during long periods of cloudy weather, three 86 AH Gel batteries are provided as well. To provide a clean and unobstructed view of the land they hid most of the lighting system inside artificial rocks.

The developer uses these floodlights 8 hours a night. With the electrical rates of 12 cents per kWH, batteries lasting 10 to 15 years, a warranty on the solar panel for 25 years, and LED light lifespan of 50,000 hours, he expects this system to pay for itself in 5 years.

If you consider the alternative cost for running 120volt electrical lines this solar powered lighting system paid for itself immediately.
