Title: Ryoichi Tanaka: Innovator in Automotive Lighting Technology
Introduction
Ryoichi Tanaka is a notable inventor based in Chita, Japan. He has made significant contributions to the field of automotive lighting technology, holding a total of 2 patents. His work focuses on enhancing the safety and functionality of vehicle signal lights.
Latest Patents
Tanaka's latest patents include a "Lighting control apparatus for signal lights" and a "Flasher device for automotive vehicles." The lighting control apparatus is designed to detect disconnections in signal lights, such as flashers, by utilizing a detecting resistor element that converts the ON current into a voltage signal. This voltage signal is then compared to a reference voltage to determine if the signal lights are functioning correctly. If a disconnection is detected, the apparatus doubles the oscillation frequency of the signal light, allowing for effective monitoring of the light's status.
The flasher device features a printed circuit board enclosed in a casing, with connections to a battery, direction indicating lamp, and ground. It includes a relay section that ensures the main lamp current flows through a current detecting resistor, thereby preventing excessive current from passing through the copper foils on the printed circuit board. This design enhances the reliability and efficiency of the flasher device.
