Xicato Secures LED Tech Patents

Photonics Spectra
Jul 2011
Xicato, a solid-state lighting company based in San Jose, Calif., was issued US Patent Nos. 7942556 and 7942540 for its Corrected Cold Phosphor Technology for LED lighting applications. Patent 7942556 addresses fundamental aspects of the technology, which involves separating different phosphors within a light-mixing chamber, with one type used on a sidewall and another type on a top element. It solves several problems associated with using LEDs in many lighting applications, said Xicato’s CEO Menko DeRoos. “As a result of the advantages inherent with this technology, we believe our products are able to maintain their lumen output and even color temperature over a 50,000-hour operating life.”
