Latest Patents

The provided information lists one patent for Kamakura: “Wavelength Conversion Device and Illumination Device.” The invention combines a flat, phosphor-containing plate with two groups of metal nanoantennas. The phosphor emits fluorescence when excited by light. A first nanoantenna group is arranged beneath the phosphor at a specified pitch, with translucent material filling the spaces between the antennas and covering the phosphor’s lower surface. A second group of nanoantennas is arranged at another pitch on the phosphor’s upper surface. Together, these components form a wavelength conversion structure for an illumination device.

Career Highlights

Kamakura’s listed professional affiliations include Kyoto University and Stanley Electric Corporation. His patent reflects work at the intersection of phosphor materials, nanostructures, and lighting devices.
