  • Point-like lamp with anode chimney
    Patent number: 6578970
    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.
