Abstract: A high-intensity arc lamp comprises a glass envelope with a pressurized gas atmosphere. A cathode and an anode structure are disposed within. A pointed tip of the cathode is juxtaposed by a central hole in a face of the anode and a small gap between them. Such central hole is vented away from the arc down inside the anode structure. During operation, heat from the arc at the entrance to the central hole drives a wind of xenon gas down through such vents in the anode structure.

Abstract: A discharge lamp arc tube in which a pair of electrode assemblies each having an electrode rod, a sheet of molybdenum foil and a lead wire integrally series-connected to one another have respective molybdenum foil containing regions pinch-sealed with glass, and electrodes are disposed opposite to each other in a closed glass bulb containing a light emitting substance or the like enclosed therein. The surface of the sheet of molybdenum foil sealed at each of the pinch seal portions has a micro-asperity surface roughened by an etching treatment including oxidation and reduction, so that silica glass is closely packed in the micro-asperity of the surface of the sheet of molybdenum foil. As a result, the adhesion (mechanical bonding strength) in the interface between silica glass and molybdenum foil is improved so that foil rising is suppressed and, accordingly, the lifetime of the arc tube is extended.
