Title: Shinya Misonou: Innovator in Discharge Lamp Technology
Introduction
Shinya Misonou is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of discharge lamp technology, holding 2 patents that showcase his innovative approach to improving the efficiency and performance of arc tubes.
Latest Patents
Misonou's latest patents include a groundbreaking design for an arc tube of a discharge lamp that features electrode assemblies receiving vacuum heat treatment. This design integrates an electrode rod, a molybdenum foil, and a molybdenum lead wire into a single electrode assembly. The assembly undergoes vacuum heat treatment at temperatures ranging from 200 to 800°C, which effectively reduces the water content to 10 ppm or less, and ideally to 3 ppm or less. This process also removes any oxide film on the electrode assembly, resulting in an arc tube that minimizes flicker, achieves a luminous flux of over 3000 lumens, and lowers the starting voltage to approximately 15 kV.
Another of Misonou's patents details a method and apparatus for welding a shroud glass tube in an arc tube for a discharge lamp. This method involves secondary welding of one end of a shroud glass tube while maintaining a negative pressure inside the tube. The process includes discharging air and introducing an inactive gas through a rotatable magnetic fluid seal unit, allowing for uniform heating and melting of the glass tube, which is then welded to the arc tube body.
