Abstract:
The invention relates to a light source (1) with a discharge vessel (2) which is filled with a filling gas, and with an electron beam source (4) arranged in vacuum or in a region of low pressure, which source (4) generates electrons (12) and propels them through an inlet foil (8) into the discharge vessel (2).According to the invention, the inlet foil (8) comprises a diamond layer.
Abstract:
A gas discharge tube, wherein a stem (4) forming a sealed case for the gas discharge tube is provided with a flange portion (4A) integral therewith, this enabling a lamp assembling operation to be simplified without requiring an operation for combining and fixing the flange portion (4A) with and to the gas discharge tube, the gas discharge tube to be easily mass-produced, and, moreover, a positioning hole (22) provided in advance in the flange (4A) to be utilized to fix the gas discharge tube (1) to an external stem setting portion (17), whereby a more accurate lamp setting operation can be carried out.
Abstract:
A gas discharge tube (1), wherein a side tube member (14) is formed of glass with a metal employed for joint portions of a stem (4) and side tube member (14), so as to prolong the lifetime of the discharge tube while lowering a discharge tube assembling temperature, a first metal circumferential portion (15) provided on the stem (4) and a second metal circumferential portion (16) provided on the side tube member (14) being utilized as the joint portions, this enabling the discharge tube (1) to be miniaturized.
Abstract:
Die Erfindung betrifft eine Laseranregungslampe mit einer Entladungsröhre und einer heiß betriebenen Kathode (1) in Form eines Stifts deren Gasraum im Bereich der Stiftkathode vermindert ist sowie ein Verfahren zu deren Herstellung bei dem durch einen weiteren Verfahrensschritt der Gasraum bzw. der freie Querschnitt um die Kathode verringert wird sowie deren Anwendung als Pumplichtquelle für laseraktive Medien.
Abstract:
The present invention relates to an arrangement for emitting light comprising: a hermetically sealed casing (4) including a transparent or translucent window (10); a layer (3) of a fluorescent substance arranged within said casing covering at least a major part of said window; an electron emitting cathode (1) arranged within said casing for emission of electrons; and an anode (2). Said casing is filled with a gas suitable for electron avalanche amplification. Said cathode and anode are, during use, held at electric potentials such that said emitted electrons are accelerated and avalanche amplified in said gas; and said layer is arranged to emit light through said window in response to being bombarded by avalanche amplified electrons and/or in response to being exposed to ultraviolet light as being emitted in the gas due to interactions between the avalanche amplified electrons and the gas.
Abstract:
A light source (10D) has a rear glass substrate (200) and a front glass substrate (202) having a plate surface disposed in facing relation to a principal surface of the rear glass substrate (200). The plate surface of the front glass substrate (202) is coated with a phosphor. A two-dimensional array of electron emitters (12B) is disposed on the principal surface of the rear glass substrate (200). A space (230) defined between the rear glass substrate (200) and the front glass substrate (202) is filled with a gas (232). The gas (232) may be an Hg (mercury) gas or an Xe (xenon) gas.
Abstract:
The invention relates to a light source (1) with a discharge vessel (12) which is filled with a filling gas, and with an electron beam source (2) which is arranged in vacuum or in a region of low pressure and which generates electrons, propelling the latter through an entry foil (10) into the discharge vessel (12). According to the invention, an electric field can be generated inside the discharge vessel (12).
Abstract:
A gas discharge tube (1) having a layer of coating (21) comprising a glass material or a ceramic material on either or both of an inner surface (22A) and an outer surface (22B) of a side tube body (22), so that the side tube body (22) can be formed of various materials irrespective of the nature of a gas sealed in the interior of the gas discharge tube, this enabling the diversification of the worked shape of the gas discharge tube and the miniaturization of the same tube to be compatible with each other, and the mass production thereof to be carried out freely.
