Title: Innovations by Toshihiko Sasai
Introduction
Toshihiko Sasai is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of lighting technology, holding a total of 5 patents. His work focuses on developing advanced illuminating devices and power supply systems for illumination.
Latest Patents
One of his latest patents is an illuminating device and illuminating method. This device includes a variety of LEDs that emit light with different color temperatures. It features multiple LED lighting circuits that independently control the LEDs for each color temperature. Additionally, a control unit selects between two modes: one that adjusts the overall illuminance of the LEDs and another that changes the colors of the emitted light. This innovation also corrects any illuminance differences that may arise during the color adjustment process.
Another significant patent is for a power supply for illumination. This system incorporates a detection circuit and a control circuit. The detection circuit compares an AC voltage with a first threshold voltage to detect variations in the conduction state of phase control. It also identifies a zero-cross point of the AC voltage by comparing it with a second threshold voltage. The control circuit then outputs an output current based on the duration of the conduction period, enhancing the efficiency of the illumination system.
