Title: Tomoyuki Seki: Innovator in High-Intensity Discharge Lamps
Introduction
Tomoyuki Seki is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of lighting technology, particularly in the development of high-intensity discharge lamps. With a total of 3 patents to his name, Seki's work has had a considerable impact on the industry.
Latest Patents
One of Seki's latest patents is for a metal halide lamp. This innovative lamp comprises a pair of electrodes and a discharge vessel filled with at least one metal halide, which includes at least one rare earth metal halide, halogen in excess of the stoichiometry of the metal halide(s), mercury, and a rare gas. The amount of mercury used ranges between 7.7 mg/cc and 9.9 mg/cc, while the excess halogen is 25-100% (in terms of atoms) of the halogen included in the metal halide(s). The rated tube power for a 200V rated tube voltage is between 2000 W and 3000 W.
Another significant patent by Seki is for a high-pressure discharge lamp with seal coating. This lamp is characterized by a single-tube, high-intensity discharge lamp or a double-tube high-intensity discharge lamp, which has an outer housing formed of quartz. A film with desirable heat conductivity and emissivity is formed on the surface of each sealing portion, allowing the temperature at the distal end of the molybdenum foil in the sealing portion to be maintained at about 350°C or less while the lamp is burning.
