摘要： A direct-current-lighting, ultra-high-pressure mercury lamp that is resistant to loss of transparency even after being lit for a long period, and has little wastage of electrodes and particularly the cathode tip, and also exhibits a long service life. The direct-current ultra-high-pressure mercury lamp includes a cathode and anode of tungsten facing each other within a quartz glass tube, and a cathode coil which is wrapped around the cathode. The cathode is composed of tungsten doped with potassium, and the anode is composed of tungsten having a purity of at least 99.99%. The cathode coil can also be advantageously formed of tungsten having a purity of at least 99.99%.

摘要： A sealing body (5) of a tube lamp using a functional gradient material in which proceeding from electrically conductive areas into the vicinity of welds on one side tube (2) and in outer leads (6) oxidation is suppressed, and in which the service life of the tube lamp is prolonged. The sealing body (5) of a tube lamp consist of a functional gradient material which is formed by mixing of a dielectric material and an electrically conductive material, the mixing ratios in the longitudinal direction being different continuously or incrementally, and in which one end forms a dielectric area and the other end forms an electrically conductive area, and by at least one part of the external surface of this electrically conductive area and/or at least one part of outer lead (6) projecting from sealing body (5) being jacketed with an atmosphere shielding layer (7).
