Latest Patents
One of Sugihara's latest patents is a short-arc discharge lamp designed to minimize the phenomenon of foil floating between the metal foil located in the foil sealing area and the sealing quartz component. This design aims to prevent cracks from forming in the foil sealing area, gas leakage from the lamp, and premature breaking of the lamp. The lamp includes electrodes located in an emission space, a metal foil electrically connected to the electrodes, and a quartz tube part surrounding the metal foil. The sealing quartz component is in contact with the inside of the metal foil, ensuring the sealing of the emission space. The lamp operates with an electrical input power rating of greater than or equal to 4 kW and an operating pressure during luminous operation of greater than or equal to 2×10 Pa, using direct current.
Another notable patent involves a short-arc discharge lamp that includes a light-emitting tube with at least 15 mg/cc of mercury sealed inside. This lamp features an anode and cathode facing each other within the light-emitting tube, along with a heat-release layer covering a substantial portion of the outer surface of the cathode. When provided with electricity having a current value of at least 50 A, the lamp achieves an inter-electrode power value defined by a specific ratio, enhancing its performance.
