Title: Mahito Hamada: Innovator in Light Emitting Devices
Introduction
Mahito Hamada is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of light emitting devices, holding a total of 3 patents. His innovative designs focus on enhancing the functionality and safety of lighting technologies.
Latest Patents
One of his latest patents is a light emitting device designed to provide countermeasures against static electricity while maintaining a compact size. This device features both a first and a second conductor pattern on an insulating board. In this design, a first LED chip with a high electrostatic breakdown voltage is connected to the first conductor pattern, while a second LED chip with a low electrostatic breakdown voltage is linked to the second conductor pattern. The LED chips are encapsulated with resin on the insulating board, and the first conductor pattern is strategically positioned to act as a lightning rod, protecting the second LED chip from static electricity.
Another notable patent involves an LED lamp that incorporates a copper film bonded with a resist. In this process, a copper film is plated onto a substrate, and a resist is bonded in a ring shape. Nickel and gold films are then applied to the exposed areas of the copper film. An adhesive agent is used to bond the lamp house to the substrate, and a transparent epoxy resin is packed and hardened to ensure durability. This design prevents separation caused by thermal stress due to the large contact area provided by the copper's fine irregularities.
