Case Study: Meyda Tiffany creates world’s largest LED chandelier
Meyda Tiffany, with engineering support from Luxeon Lighting Network member ARAD and Future Lighting Solutions, has created the world’s largest LED chandelier using 160 white LUXEON K2 LEDs. At 35 feet wide, 17 feet tall, and 6500 pounds, this gorgeous example of the legendary Tiffany style is the centerpiece of the restored historic Stanley Center for the Arts in Utica, New York.
Just as remarkable: ARAD designed and implemented the LUXEON solution in just a few weeks. By using high-power LUXEON LEDs, they cut the theater’s electrical bill by a whopping 93%, and use just 75% of the power of the original halogen design. And the chandelier should operate for five decades without requiring a “bulb” replacement – which is important when you consider the effort of lowering a fixture weighing over 3 tons!

Case Study: Illumivision Illuminates the Big Dam Bridge
When the sister cities of Little Rock and North Little Rock, Arkansas, built a new pedestrian bridge on top of the Murray Dam that spans the Arkansas River, they wanted to turn the span into a monument they could be proud of. Affectionately known as the “Big Dam Bridge”, it became the world’s longest bridge dedicated to pedestrian and recreational use.
When it came to lighting their bridge, designer John Rogers and Edmonton, Alberta-based Illumivision delivered an innovative lighting solution that has become not only a nightly spectacle for citizens, but a tourist attraction for visitors to the state capital.
 The solution uses color-changing Light Wave LX fixtures from Illumivision, each of which incorporates 36 red, green and blue LUXEON high-power LEDs. These fixtures provide a much more flexible alternative to metal halide lighting, providing full, remote dimmability and color control. They are also much lighter, more durable, have a much longer life, and consume a fraction of the energy of metal halide, saving the city thousands of dollars per year in energy costs.

Simplicity is Accessing Engineering Design Tools Online
Philips Lumileds and Future Lighting Solutions have an ongoing commitment to simplifying the design and implementation of LUXEON-based light engines and luminaires. You may already be familiar with the many online development tools available on our websites.
Philips Lumileds has introduced a new Design Resources section on the its website. The Design Resources area includes optical, mechanical and electrical models for LUXEON Rebel and LUXEON K2 that can be downloaded and immediately used in designers’ software applications to reduce development time, speed time to market, and deliver the best possible solutions and products.
These model files include raysets, optical source models, footprint files, 3D-CAD files, PCB layout tool library models, and Spice models for electrical simulation… all in a variety of formats.

LED Myth
Myth: Power LEDs that claim they can be driven at 1A are usable at 1A.
LUXEON Fact: When most power LEDs rated for drive currents of 1A are actually driven at 1A, thermal management becomes prohibitively difficult. Ultimately, the maximum junction temperature that must be maintained to ensure lumen maintenance lifetime is exceeded.
LUXEON K2 with TFFC is the exception. The first LED to be binned and tested at 1000 mA, it is designed to be capable of being driven continuously at 1A while maintaining thermal and lumen maintenance specifications.
To see how LUXEON K2 with TFFC can outperform other LEDs at 1A, visit the Useable Light Tool from Future Lighting Solutions and see the results for yourself.
Did You Know: Cities have been going Green since 1999 using LUXEON LEDs
It turns out that many of the cities in the US are well on their way to being “Green” and have quietly been contributing to the reduction of green house gases for most of this decade with little credit for or notice of their efforts.
According to our calculations, there are over 300,000 traffic signals using more than 23 million LUXEON LEDs already saving over 2.4 TWh of power per year in the U.S. compared to conventional incandescent sources.
How “Green” has the decision by so many cities using LED Traffic signals been?
Very Green! — our cities efforts have resulted in the following savings.
- Over 2.75 million tons of CO2 removed from the atmosphere
- The electrical power consumption of over 322,000 average US households
- Over 480,000 cars removed from the road for one year
- CO2 mitigating impact of over 687,000 acres of forest
- More than 5.2 million barrels of crude oil
- More than 1 million tons of coal
- More than 100 million gallons of gasoline
- Almost half of a major (1000 MW) coal-fired power plant
In 1999 when Lumileds was founded and began providing solutions for traffic signals, “Green” was not an issue at the top of everyone’s mind. Lower energy costs, reliability and high reliability were the compelling benefits – and they were quickly proven.
Today, the vast majority of signals in the U.S. use LUXEON LEDs. Which turns out to have been a very “Green” decision indeed. |
