  • Patent number: 6597114
    Abstract: A lamp seal (10, 30) of functionally gradient seal material and a lead bar (13, 32) that is fixed to the seal piece (11, 31), which seal piece is formed an inorganic layer with insulative properties and a number of mixed layers that are each mixtures of conductive inorganic materials and insulative inorganic materials, such that the proportion of conductive inorganic materials increases gradually in the direction of layering. A hole is formed extending in the direction of layering such that the lead bar can be fixed into the seal material with a sleeve-shaped metallic part made of a high-melting-point metal separating the outer periphery of the lead bar from the seal material. A lamp made with an air-tight seal formed of that lamp seal of functionally gradient material.
