Abstract: A flange portion 4A is integrally formed with a stem 4 which forms a sealing envelope for a gas discharge tube. Accordingly, operation for building and fixing the flange portion 4A is not necessary, so that lamp assembly operation is simplified, and mass production is facilitated. In addition, when a gas discharge tube 1 is to be fixed to an external stem setting portion 17, lamp setting is enabled at higher precision by utilizing positioning holes 22 formed in the flange portion 4A in advance.

Abstract: In a gas discharge tube 1 in accordance with the present invention, a side tube 22 is formed from a metal, the outer periphery of the stem 4 is provided with a joint portion 15b made of a metal, and the latter is joined to a metal-made joint portion 16 of the side tube 22 by welding, whereby the assembling is made easier by welding, while the gas discharge tube 1 itself can attain smaller dimensions. Also, since the side tube 22 is small and made of a metal, its handling improves greatly. Further, since side tube 22 is formed from a metal, the gas discharge tube 1 is encouraged to have a wider range of processed forms and attains a prospect for mass production.

Abstract: A gas discharge tube comprises an envelope (11) for sealing a gas; lead pins(13-16); and a light-emitting assembly (20). The light-emitting assembly includes: a focusing electrode support member (21) of an insulator; a hot cathode (31) for emitting thermoelectrons; an anode (24) for receiving thermoelectrons; a focusing electrode (29) for converging paths of thermoelectrons; a spacer (50) of an insulator or a conductive material being arranged between the focusing electrode support member and the anode; and an anode support member (22) of an insulator for pushing the anode onto the focusing electrode support member through the spacer. A gas discharge tube having a long service life and capable of improving the operational stability during long-time continuous light emission can be provided.

Abstract: In a gas discharge tube 1 in accordance with the present invention, one or both of the inner wall face 22A and outer wall face 22B of a side tube body 22 are provided with a coating 21 made of a glass material or ceramics. As a result, the side tube body 22 can be made of various materials regardless of properties of the gas filling the inside, whereby the gas discharge tube 1 can have a wider range of processed forms and smaller dimensions at the same time, and its mass production can freely be carried out.

Abstract: In a gas discharge tube in which a sealed envelope at least a part of which transmits light is filled with a gas, and electric discharge is generated between anode and cathode sections disposed within the sealed envelope, so as to emit predetermined light outside from the light-transmitting part of the sealed envelope, the anode section is mounted on an insulating anode support member, an insulating electrode support member having an opening for exposing the anode section is mounted on a surface surrounding the anode section, a focusing electrode having a focusing opening projecting toward the anode section is further mounted at the front face of the opening, and the cathode section is disposed on the anode support member or focusing electrode support member so as to be spaced from the focusing opening.

Abstract: While high heat is generated in the anode section 6 in the gas discharge tube 1 in accordance with the present invention during its use, the heat is transmitted to the stem 4 by way of the anode support plate 5 due to a configuration in which the anode support plate 5 abuts against the stem 4, and is released outside from the stem 4, whereby the cooling efficiency of the anode section 6 is improved. Since the anode section 6 employs not a floating structure including stem pins 10 interposed therein but a configuration in which it is seated on the stem 4 by way of the anode support plate 5, the anode section 6 is stabilized on the stem 4, whereby the resistance to vibration improves. Also, for assembling the anode section 6 into a sealed envelope 2, it will be sufficient if the anode support plate 5 is mounted on the stem 4, which contributes to improving the easiness in assembling the gas discharge tube 1.
