Color LEDs Enable Architectural, Entertainment, And Horticultural Applications

29 Aug

Philips Lumileds adds a deep-red LED to its Luxeon family, while Lebelight Technology claims new brightness record in green LEDs.

While phosphor-converted white LEDs are touted for general-illumination and backlighting applications, colored LEDs can serve in many more applications in architectural, entertainment, horticultural, and other segments. Philips Lumileds has added to its color portfolio with a new deep-red emitter. Lebelight Technology has a green emitter that it says can produce 150 to 160 lm.

Philips has a Luxeon Rebel color portfolio that ranges from royal blue (440-460 nm) to deep red (650-670 nm). The deep-red LED is the recent addition and targets applications such as horticulture and entertainment. Moreover, Philips says that some governments require the deep-red color in railway- and roadway-signaling applications.

Deep-red for safety and horticulture

The deep-red LED differs from the standard-red (620-645 nm) offering. The deep-red color is more visible in safety-centric application and Philips rates it at double the drive current of most of the Luxeon color portfolio. The emitter generates 720 mW of radiometric power or radiant flux at 700 mA.

“For more than a decade, Luxeon LEDs have been the first choice for enlivening city centers and architectural wonders, bringing drama to concerts and performances, and ensuring people can move safely on our public transit systems,” said Steve Barlow, senior vice president of sales and marketing at Philips. “We are committed to the continuous improvement of our color portfolio and have delivered substantial light output increases.”

Horticulture could prove to be a major consumer of the deep-red LEDs. It turn out that the 660-nm wavelength corresponds to peak chlorophyll absorption in plants as we covered in an article on LED-based horticultural lighting. Plant factories and green houses are moving away from broad-spectrum lights to ones that provide specific wavelengths hoping to induce better plant grow with less energy. Osram has been keen to support such applications introducing deep-red LEDs last year.

The other color in the Luxeon portfolio that has a specialty applicability is the royal-blue LED. It too is characterized at 700 mA delivering 1120 mW, and targets remote-phosphor-based general-lighting applications. Philips introduced the royal-blue LED earlier this year, and we just ran a news story on the remote-phosphor topic with Cree introducing a royal-blue LED.

Brighter green LEDs

Green LEDs, meanwhile have been challenged in terms of lumen output due to a physics phenomenon called the charge separation effect. Research organizations such as Rensselaer Polytechnic Institute (RPI) have been working diligently on brighter green LEDs.

Lebelight Technology of Xiaoyi, China claims to have produced a green LED that delivers 150 to 160 lm at 350 mA of drive current. If the company can cost-effectively produce such a product it could enable advances in general lighting, backlighting, and specialty applications such as horticulture.

Large-screen TV backlights for example can benefit from direct backlighting using clusters of red, green, and blue (RGB) LEDs that improve the color gamut of the picture. But TV makers have gone away from the RGB scheme, in part because they need to combine two green LEDS with each red and blue LED to achieve consistent brightness. Likewise, RGB-based general-lighting fixtures can produce tunable color, but the available green LEDs don’t deliver the needed efficiency.

LEDs Go with The Flow in New York City Waterfalls

15 Oct

A series of man-made waterfalls installed around New York Harbor were lit using LED lighting fixtures to simulate the effect of moonlight on the water.

The New York City Waterfalls public art installation, by artist Olafur Eliasson, comprised four man-made waterfalls in the New York Harbor situated along the shorelines of Lower Manhattan, Brooklyn and Governors Island. One of the key features of the waterfalls was their use of LED lighting behind the water flow to simulate the effect of moonlight.

The Waterfalls ranged from 90 to 120-feet tall and were on view from June 26 through October 13, 2008. The project was commissioned by the non-profit Public Art Fund in collaboration with the City of New York.

Each waterfall pumped 35,000 gallons of water per minute from the East River to the top of a scaffold. As the water flowed over the lip of the falls it was illuminated by LED fixtures.

Each waterfall utilized a continuous row of assembled 5 feet sections of LED fixtures, supplied by Boca Flasher Inc, with a mixture of cool and warm white LEDs controlled by 3 separate channels. The total wattage was 300W per 5 ft. section at 100% output, while the actual operating load was 15-25%, depending on the site.

Light from the LED fixtures grazed the back of the water, penetrating the flow and accentuating the effect of wind gusts and changes in water flow rate. A custom baffle just below the LED source prevented glare at normal viewing angles.

The Lighting Designer for the project was Michael Mehl of Jaros, Baum & Bolles. “Working with LEDs offered us very interesting possibilities both technically and aesthetically in realizing Eliasson’s artistic vision,” he said.

Some immediate concerns over the use of LEDs, such as color rendering and heat dissipation, were overcome by the nature of the exterior environment in this project, said Mehl. “Unlike prior projects we have worked on, LEDs were not initially chosen for their promise of extended life, since the project had a limited installation period of only four months of operation,” he added.

Hiding the source was the biggest challenge, so that the water would appear as if lit by moonlight. “The size-to-light output ratio of the LEDs favored them over conventional lamp sources,” said Mehl. “We focused our design attention on the caveats of the technology, such as lamp-to-lamp color consistency and optics.”

The designer also believes that a critical component to using LEDs, beyond the specific source, is the choice of manufacturer. “Architects and lighting designers should choose a manufacturer who understands the technology and can aide the design process considerably. Since LEDs are a compilation of components, the best friend the lighting consultant can have with the burgeoning technology is to work with a manufacturer who understand the nuances of LEDs and can integrate ever-evolving aspects of the technology, while delivering on the conventional design process of conception through installation.”
