    摘要: A discharge lamp which emits light by an electric disacharge by applying an AC voltage between a pair of ceramic cathodes (1) and has a long service life. Each ceramic cathode (1) is constituted of an electron emitting material (3) constituted of a conductive oxide having an aggregate type porous structure which contains a first component composed of at least one element selected out of Ba, Sr, and Ca, a second component composed of at least one element selected out of Zr or Ti, and a third component composed of at least one element selected out of Ta and Nd and a conductor or semiconductor layer which is formed on the surface of the conductive oxide and composed of at least one kind selected out of the carbide, nitride, and oxide of Ta or Nb and a bottomed cylindrical container (2) for storing the material (3). In a valve (4), in addition, an Ar, Ne, Kr, or Xe gas or their mixed gas is sealed under a pressure of 10-170 Torr.

    摘要: The electrode for a ceramic cathode fluorescent discharge ensures a high density of electron current, has a high resistance against heat shock, and is less damaged by sputtering. The diameter of a tube using this electrode can be small. The material for the electrode is prepared using 0.5 to 1.5 mol of a first component selected from BaO, CaO or SrO, 0.05 to 0.95 mol of a second component selected from ZrO₂ or TiO₂, and 0.025 to 0.475 mol of a third component selected from V₂O₅, Nb₂O₅, Ta₂O₅, Sc₂O₃, Y₂O₃, La₂O₃, Dy₂O₃, Ho₂O₃, or 0.05 to 0.95 mol of the same selected from HfO₂, CrO₃, MoO₃, WO₃. Also, the electrode is fabricated by granulating this material and putting the lump, granular, or porous material in a bottomed cylindrical semiconductor magnetic container, and then, burning and reducing it. The mercury dispenser of the ceramic cathode fluorescent discharge lamp using this electrode is arranged in series between the bottomed semiconductor magnetic cylinder and the lead out section of the lead wire.

    摘要: An optical radiation source in the spectrum range from UV to IC based on the gas discharge with a hollow anode is presented. The dis­charge has been realized in a diode consisting of a cathode and a special type of a hollow anode whose inner apperture surfaces only are conductive. Small surface of the anode aperture and a high density of the discharge current provide a high brightness of the source with the intensive atom and/or ion spectrum.

    摘要: High pressure sodium lamps have been subject to progressive reduction in pressure of contained sodium with attendant reduction in lighting quality. It has now been discovered that modification of lamp components permits the pressure of contained sodium to be maintained at higher. levels. Emission materials enclosed within the lamp are altered to limit reactive oxygen in the lamp atmosphere. A thermionic electrode is equipped with an improved emission mix composition as illustrated in areas B and C of the triaxial plot of Figure 3.
