Intematix Corp., a leading manufacturer of phosphor solutions for LED lighting, today announced that U.S. patent No. 8,597,545 was issued on December 3, 2013 by the United States Patent and Trademark Office. This patent covers novel formulations for red emitting, nitride based phosphors and include products in the company’s XR phosphor product family. This award extends Intematix’s innovation leadership in phosphors that improve the performance of LED lighting.
“This patent confirms XR red nitride phosphor as a proprietary Intematix innovation moving LED lighting to higher color quality and reliability,” said Yi-Qun Li, Chief Technology Officer for Intematix. “We look forward to working with our customers on the next generation of LEDs with full spectrum performance and long lifetimes.”
Red nitride phosphors play a central role in extending the color range of LED applications like general lighting and displays including TVs, monitors and tablets. Intematix red nitrides combined with GAL® green phosphors, arrangements covered by the company’s previously issued patents, enable near-perfect color rendering up to 98 CRI. The XR red nitride also leads in color stability with less than perceptible 2SDCM measured color shift in accelerated aging testing. This performance results in lighting applications with long term color quality and consistency.
