Title: Syouhei Maeda: Innovator in Lighting Technology
Introduction
Syouhei Maeda is a notable inventor based in Yokosuka, Japan. He has made significant contributions to the field of lighting technology, particularly through his innovative patents. With a total of 3 patents, Maeda has demonstrated his expertise and creativity in developing advanced lighting solutions.
Latest Patents
One of Maeda's latest patents is a dielectric barrier discharge lamp lighting device. This device features an inside electrode positioned along the tube axis within an airtight container that possesses ultraviolet transmission properties. The lamp also includes an outside electrode with a semicircular shape, which is arranged in close contact with the airtight container. An excimer-forming gas is sealed within the container, and the device operates by converting AC voltage from a power source into DC voltage through a converter. A high-frequency wave is generated by an inverter based on the supplied DC voltage, inducing a dielectric barrier discharge that irradiates ultraviolet rays. Additionally, the converter is designed to connect the outputs of multiple DC power sources in series, allowing for optimal luminous efficiency by adjusting the number of sources.
Another significant patent by Maeda is a lighting device for a discharge lamp. This invention includes an inductor that performs a chopper operation by turning on or off a first switching element, a MOSFET, to obtain an increased voltage. It is arranged on the secondary side of a transformer, enabling the generation of a high voltage from a low DC power source. By synchronizing the on-duties of the switching elements in the inverter circuit, the lifespan of the lamp can be improved.
