USPTO Issues Patents to Intematix’ Phosphors for Lighting and Display Applications

Intematix Corporation, a leading manufacturer of phosphor solutions for LED lighting, today announced that patents covering its green and yellow GAL® phosphor products and certain LuAG phosphors have been issued by the United States Patent and Trademark Office.

Patent numbers 8,529,791 and 8,475,683 regarding green and yellow emitting, garnet-based phosphors used in lighting and display applications were issued on September 10, 2013 and July 2, 2013, respectively. Intematix GAL phosphors enable exceptional performance for LED lighting compared to other options in these color ranges.

GAL phosphors’ light emission characteristics result in higher Color Rendering Index (CRI) in LED lighting applications. When combined with red nitride or other red phosphors, arrangements also covered by these patents, CRIs up to 98 (out of 100) have been demonstrated.

“By using our GAL phosphors, LED solutions may be designed for efficient performance at CRIs greater than 90,” said Yi-Qun Li, Chief Technology Officer at Intematix. “This technology is instrumental to meeting new standards like California’s Quality LED Lamp Specification.”

GAL phosphors also provide up to 95% lumen maintenance at 200°C phosphor temperature, enabling LEDs of all types, including mid-power LEDs, to operate at higher output and efficacy. The products are also versatile design tools for LEDs used in displays like TVs and tablets.
