Title: Takafumi Sakuramoto: Innovator in Light Pipe Technology
Introduction
Takafumi Sakuramoto is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, particularly in the development of light pipes and polarized-light sources. With a total of 17 patents to his name, Sakuramoto continues to push the boundaries of innovation in his field.
Latest Patents
One of Sakuramoto's latest patents involves a light pipe that is created by laminating a polarized-light scattering plate onto a light-transmitting resin plate. This innovative design incorporates fine birefringent domains that exhibit anisotropy in scattering. The polarized-light scattering plate consists of a transparent film containing fine domains made from a liquid crystal polymer. This polymer demonstrates nematic properties at temperatures below its glass transition temperature, which is set at 50°C or higher. The light pipe can also include additional features such as a specular reflection layer, a polarization-retaining lens, and a light diffusion layer. Furthermore, it may be equipped with a light source on at least one side to function as a planar polarized-light source.
