LLF receives first patent

LED Lighting Fixtures Inc (LLF) of Morrisville, NC, USA has been issued with its first patent (US Patent no. 7,213,940 ‘Lighting Device and Lighting Method’). This covers LLF’s core technology for what it claims is a unique approach for creating white light that allows it to use any chip source or package available, says founder and co-inventor Tony van de Ven.

White light is typically produced from LEDs by either coating true blue LEDs with a YAG phosphor or combining red, green and blue LEDs. LLF’s approach delivers high efficancy and excellent color quality, the firm claims.

“LLF’s technology will deliver the first high-volume, energy-efficient lighting products to the market and our fixtures should outperform all conventional sources, including compact fluorescent bulbs,” van de Ven claims.

LLF demonstrated its LR6 products and its new LR4 four-inch downlight product at last week’s 2007 Lightfair International Trade Show in New York City. LLF is also displaying two new commercial prototype lights: a high-output recessed downlight that delivers over 1500 lumens; and a recessed 2 foot by 2 foot architectural luminaire that produces over 3500 lumens. Both designs are targeted to replace existing fluorescent troffer fixtures that serve as a standard for commercial lighting.

LLF currently uses XRE white LEDs manufactured by Cree Inc of Durham, NC, USA for its products. LLF has over 50 additional patents pending in the USA and subsequent patent filings worldwide.
