Quantum dot lighting for brightness and colour

Nexxus Lighting : 07 May, 2009  (New Product)
Nexxus Liging creates new bright lighting system in conjunction with QD Vision
Nexxus Lighting and QD Vision have unveiled the world's first quantum dot lighting solution that combines the efficiency of LED lighting with the warm colour of incandescent bulbs. The new lamp integrates a quantum dot optic with cool white LEDs to produce colour-rich, true incandescent, warm white light which can provide over 80% energy savings and lasts up to 25 times longer than comparable halogen lighting alternatives.

Architects and the lighting design community have been demanding a higher CRI LED product without the efficacy losses typically associated with these lamps. The new Quantum Light optic developed by QD Vision, integrated with Nexxus Lighting's patented Array Lamp designs and patent pending technology, solves this critical issue. The Nexxus Lighting Array lamp with the Quantum Light optic delivers a true incandescent, warm white, 2700 degree Kelvin lamp with a colour rendering index of 90 or greater at over 65 lumens per watt.

The companies will demonstrate the product and technology at Lightfair International 2009 at the Javits Centre in New York, New York, May 5 - 7, 2009, Booth #675. The Array Lighting Quantum Light solution for all Nexxus Lighting Array Par 30, MR 16 and Par 16 lamps is expected to be available in the 4th quarter of 2009, with volume production in early 2010.

"Nexxus Lighting's new Array LED lamp line is a perfect application for our quantum dot technology," said Dan Button, President and CEO of QD Vision. "This productive partnership, combining QD Vision's Quantum Light optic and the leading design capabilities of Nexxus Lighting, has resulted in a product the market has long been demanding - lamps with exceptional colour quality and power efficiency together."

"We are excited to add this new high color rendering, true incandescent warm white color choice to our successful Array LED lamp product offering," stated Mike Bauer, President and CEO of Nexxus Lighting. "The architectural lighting community has been clear in its demand for better colour rendering performance in LED lighting, without sacrificing the efficacy gains you can achieve through solid state solutions."

The product resulting from the Nexxus Lighting/QD Vision partnership was recently demonstrated at a White House ceremony, in which President Obama announced a $1.6 billion disbursement of research funds for clean energy products. The Nexxus Lighting/QD Vision project was one of only four technologies spun out of MIT that were demonstrated at the event, which featured remarks by MIT President Susan Hockfield.

Because the Nexxus Lighting Array lamps with Quantum Light are compatible with a standard, screw-in 'Edison' base, they can easily replace incandescent and halogen lamps in existing downlight fixtures. Just in the US, the DoE estimates, the number of down lights and track heads with Edison base lamp installations equal over 139 million in commercial applications and over 262 million in residential lighting applications. Both companies expect that commercial availability of their high efficiency lamps with high colour quality will overcome a major barrier to LEDs and will accelerate the penetration of LEDs in the $4 billion US lamp market. The potential impact on the environment could be significant, a full conversion to LEDs of existing downlights and trackheads in the US (~10% of US fixtures) represents an annual savings of more than 35 billion KW hours (nearly $4 billion), which is the equivalent of nearly 6 power plants or more than 60 million barrels of oil per year.
