Title: Innovations of Junichi Takagi

Introduction

Junichi Takagi is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of light source technology, holding a total of 8 patents. His work focuses on enhancing the efficiency and effectiveness of light emission in various applications.

Latest Patents

One of Takagi's latest patents is a surface light source, which includes a method for manufacturing the same and an apparatus utilizing it. This invention involves a spotlight source that emits light in a linearly extending region through a wedge-like light conductor, which is then deflected by a prism sheet. The emitted light is directed perpendicularly to the light incident surface of the light conductor plate, featuring a narrow directivity in the widthwise direction. The light conductor plate is designed with multiple diffusion patterns in a rectangular triangular form on its bottom surface. This design allows for light reflected from the diffusion pattern to be emitted perpendicularly to the light-emitting surface of the plate. Additionally, Takagi has developed a plane light source apparatus aimed at maximizing light utilization efficiency in backlighting for reflection-type liquid crystal display panels. This apparatus ensures that light flecked from the rear face of a light guide plate is incident on a prism sheet and reflected orthogonally, enhancing the overall light emission.

Career Highlights

Junichi Takagi is currently employed at Omron Corporation, where he continues to innovate in the field of light technology. His work has been instrumental in advancing the capabilities of light sources used in various electronic devices.
