Title: Yuiko Nakagawa - Innovator in Lighting Technology
Introduction
Yuiko Nakagawa is an inventive mind based in Yokosuka-shi, Japan. He has been actively engaged in the development of innovative lighting solutions. His work focuses on creating advanced lamp and luminaire technologies that enhance the functionality and aesthetic appeal of lighting devices.
Latest Patent Applications
Yuiko Nakagawa has submitted several notable patent applications. One of his latest applications is for a lamp that includes a plurality of light-emitting sections. These sections consist of various light-emitting elements arranged side by side on a substrate, designed to emit lights of different colors. The luminous fluxes of the emitted lights can be controlled separately. The lamp also features a pipe made of a translucent material that diffuses the emitted lights, with a linear transmittance ranging from 0% to 50%. The design ensures that the distance from the lower part of the pipe to the light-emitting elements exceeds the inner radius of the pipe.
Another significant application is for a light-emitting module and illumination device. This module comprises a substrate, a light-emitting element, and a sealing member. The sealing member is primarily made of a translucent resin containing phosphor particles. It includes a main portion that covers the light-emitting element and an outer peripheral portion that contacts the substrate. Notably, the content percentage of phosphor particles is lower in the outer peripheral portion than in the main portion.
Conclusion
Yuiko Nakagawa is a promising inventor in the field of lighting technology, with innovative ideas that could shape the future of illumination. His latest patent applications reflect his commitment to advancing lighting solutions.
