Xicato Issued Patents on Corrected Cold Phosphor Technology
SAN JOSE, Calif., June 6, 2011 — Solid-state lighting manufacturer Xicato has announced the receipt of two patent issuances from the US Patent Office.
Patent 7942556 addresses fundamental aspects of Corrected Cold Phosphor Technology used in the company’s LED module products. A key differentiating aspect of the technology is the separation of various phosphors within a light-mixing chamber, with one type used on a side wall and another on a top element. The separation of phosphors from the LEDs allows the phosphors within the module to maintain a lower operating temperature, enhancing the product’s reliability over its life. In addition, by varying the side and top wavelength converting elements alongside different combinations of LED emitters, modules can be made to exact color point and rendering indices.
The technology further allows for a light source that can be readily cleaned without damaging the light-emitting phosphors, a critical benefit for outdoor applications, according to the company.
The second patent, No. 7942540, addresses ways of changing the spectral distribution of the light coming out of a module by manipulating the relative position of at least one reflector and at least one wavelength converting area within a mixing cavity, enabling the color point of the module to be “tuned.”
Xicato also announced that it has received 16 design patents — two in the US — and has 19 US patent applications in process, along with 60 foreign counterpart filings.
