Title: The Innovations of Seiichiro Yagi
Introduction
Seiichiro Yagi is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of vehicle lighting technology, holding a total of 12 patents. His work focuses on enhancing the efficiency and safety of vehicle lighting systems.
Latest Patents
One of Yagi's latest patents is a lighting control apparatus for vehicle-purpose lighting devices. This innovative apparatus contributes to power savings and prevents the deterioration of semiconductor light sources while maintaining driving safety characteristics. When the input terminal is at a low level while the vehicle is stopped, a PNP transistor is activated, allowing a source current to flow through a current detecting terminal. This action enables a switching regulator to light an LED with a beam attenuating operation of 70%, ensuring compliance with legal luminous intensity distribution. Additionally, when the upper beam is activated, the input terminal again becomes low, further decreasing the light emitting degree of the LED, allowing for a 50% beam attenuation.
Another notable invention is a vehicle lamp that features multiple lamp units, each equipped with light sources and optical units designed to emit light ahead of the lamp unit. The driving unit is configured to swivel the optical units in different strokes, enhancing the versatility and effectiveness of vehicle lighting.
