Title: Akira Tsujimoto: Innovator in Light-Emitting Technology
Introduction
Akira Tsujimoto is a prominent inventor based in Nara, Japan. He has made significant contributions to the field of light-emitting technology, holding a total of eight patents. His innovative work has paved the way for advancements in various applications of light-emitting devices.
Latest Patents
One of Tsujimoto's latest patents is a light-emitting apparatus that includes an excitation light source emitting first light. This apparatus features a light-emitting device positioned on the optical path of the first light, which emits second light with a specific wavelength in air. The design incorporates a first converging lens on the optical path of the second light. The light-emitting device consists of a photoluminescent layer that emits the second light when excited by the first light, along with a light-transmissive layer placed on top of the photoluminescent layer. Notably, at least one of these layers has a surface structure with projections or recesses arranged perpendicular to the thickness direction of the photoluminescent layer. Additionally, the light-emitting surface is oriented perpendicular to the thickness direction, allowing the second light to be emitted effectively. This surface structure is crucial as it limits the directional angle of the second light emitted from the light-emitting surface.
