A discharge vessel 11 having a double tube structure formed by a ring-shaped discharge space S between the inner tube 12 and the inner tube 1 3; one of the electrodes 15 is in close contact with a mesh formed by a conductive material such as a wire mesh. It is provided on the outer peripheral surface of the outer tube 12 and the other electrode 16 formed of an aluminum plate is in close contact with the inner peripheral surface of the inner tube 13. In the discharge space S, krypton is filled with a gas such as xenon gas. The excimer discharge is constituted by a discharge gas that forms excimer molecules (see, for example, Patent-5-200540905 (2) Literary Literature 1 and Patent Literature 2). The discharge vessel of such an excimer lamp is as follows, that is, as shown in FIG. 9, two cylindrical raw material tubes 70, 71 each having a thickness of about the same as that of the outer diameter are prepared. The two raw material tubes 71 of one of the side tubes are bent at both ends toward the radial direction to form a curved portion 72, and the two raw material tubes 7 are heated from the outer side of the tube axis direction by means of suitable heat. The two end portions of 1 are connected to φ to join the other raw material tube 70 constituting the outer tube. The inner peripheral surface of one of the inner material tubes 7 constitutes a curved portion 7 2 of the inner tube. 72A ′ Thus, the inner portion of the outer tube is obtained. A discharge vessel having a closed circular discharge space between the peripheral surface and the inner tube, the thickness of the other raw material tube 70 constituting the outer tube 11 is 11 and the thickness of one of the inner material tubes 71 is t2. Is about the same size. In recent years, in the case of an excimer lamp using a light source of a glass substrate φ device of a liquid crystal display panel, as the glass substrate is large enough to obtain a large area of light emission, it is made longer and has a length of 800 mm. The above. In such a long excimer lamp, the thickness of the outer tube is made larger from the viewpoint of the mechanical strength of the excimer and the bonding strength between the outer tube and the inner tube, and the thickness of the inner tube is greater than the thickness of the outer tube. The reason why the thickness of the inner tube is made smaller is explained in detail as follows. In order to make the excimer lamp sufficiently capable, it is obtained by making both the outer tube and the inner tube thicker. And so on, while forming the inside and outside of the front end and the outer peripheral surface of the melted 70A and. Here, for example, the cleaning type can be made as a whole lamp, and it must be made with a small structure and strong in mechanical properties. -6-200540905 (3) The inner tube is formed only by the joint with the outer tube. Because of the supported structure, the strength of the joint is reduced by its own weight. Moreover, it is not limited to these cases. There are also many cases where the thickness of the outer tube and the thickness of the inner tube are different from each other. For example, in the case of a shorter one, the inner tube is produced. The thickness is large, and the thickness of the outer tube is smaller than the thickness of the inner tube. The reason is that by reducing the thickness of the outer tube, the light transmittance is increased, and a high light output can be obtained. However, when the thickness of the outer tube and the inner tube which are different from each other is different, the heat capacity of the outer tube and the inner tube in the heating portion of the joint is different. Therefore, the two cannot be heated uniformly and cannot be sufficiently obtained. Defective joint strength, or easy to produce defects such as deformation or skew occurs at the joint, and when the excimer lamp is transported or installed, or at the early stage of lighting, there are problems caused by the structural defects of the joint. There are disadvantages of the damaged discharge vessel. φ On the other hand, if sufficient mechanical strength can be secured throughout the excimer lamp, it is desirable to make the outer tube and the inner tube thin. This reason is to suppress a reduction in electrical efficiency. Then, as described above, when the thickness difference between the outer tube and the inner tube by fusion bonding is large, the thinner may be excessively fused, and thus it may be difficult to perform the bonding. The above-mentioned disadvantages are notably the case where the thickness of the thicker of the outer tube and the inner tube constituting the discharge vessel is significantly larger than the thickness of the thinner, such as a configuration of 1.5 times or more. 200540905 (4) Patent Document 1: Japanese Patent No. 3 2 5 2 6 7 6 Patent Document 2: Japanese Patent No. 2 9 5 1 1 3 9 [Summary of the Invention] The present invention was created based on the foregoing, The purpose is to provide an excimer lamp, which belongs to the double-tube structure excimer lamp caused by the outer tube and the inner tube with different thicknesses in the central area.

The inner tube 1 3 constituting the discharge vessel 1 1 has a bent portion 1 3 A formed by bending at both ends to expand outward in the radial direction φ. The bent portion 1 3 A of the inner tube 13 and The outer tube 12 is joined to form the end wall 14 by the curved portion 1 3 A. Thereby, an airtight seal is formed between the inner peripheral surface of the outer tube 12 and the outer peripheral surface of the inner tube 13. The annular discharge space S. The outer tube 1 2 constituting the discharge vessel 1 1 is closely adhered to the outer peripheral surface thereof, and one of the electrodes [hereinafter, referred to as an “external electrode”] 1 5 ′ is provided in a mesh shape formed by a conductive material such as a wire mesh. The inner tube 1 3 is in close contact with the inner peripheral surface, and is provided with a tube made of aluminum or partially in a cross section. -10 · 200540905 (7) The other side with a notched C-shape (groove shape) with a notch Electrodes (hereinafter referred to as "internal electrodes") 1 6. The external electrodes 15 and 16 are connected to a power source device (not shown) such as a high-frequency power source. The discharge space S is filled with a discharge gas such as a gas, which generates excimer molecules by an excimer discharge occurring between the external electrode 15 and the internal electrode 16. In this excimer lamp 10, an outer tube 12 constituting a central field portion of the excimer light emission field that can efficiently use the excimer light emitted from the excimer lamp 10 is configured. The thickness and the thickness of the inner tube 13 are made different from each other, and the thickness of the thicker is made 1.5 times or more the thickness of the thinner. In this embodiment, the thickness t1 of the outer tube 12 is made larger than the thickness t2 of the inner tube 13 (tl ^ 1.5 xt2) [see Fig. 2]. The thickness of the thinner (in this embodiment, the thickness t2 of the inner tube 13) is, for example, 0.5 to 1.0 mm. In the following description, unless otherwise specified, the "thickness" refers to the thickness of the central region portion of the excimer lamp 10. In addition, the thickness of the outer tube 1 2 and the thickness of the inner tube 1 3 at the joint portion of the outer tube 12 and the inner tube 13 are made approximately the same size. Specifically, referring to FIG. 2, if the thickness of the end portion of the outer tube 12 is set to 11 and the thickness of the end portion of the bent portion of the inner tube 13 is set to 13, the following formula (1 ) And either of the formulas (2). -11-200540905 (8) Formula (1) 1 tl-t3 | ^ 0.2xtl Formula (2) 1 tl-t3 1 ^ 0.2xt3 The excimer lamp 10 having the above configuration can be manufactured as follows. That is, as shown in FIG. 2, first, the outer end is enlarged in a flared shape to extend both ends toward the outside of the radial direction: r forms a curved portion 13A φ a cylindrical inner tube for the inner tube 13 The raw material tube 20 is inserted coaxially inside the cylindrical outer tube forming raw material tube 21 having an outer diameter larger than the outer diameter of the inner tube forming raw material tube 20, and the outer tube 12 is placed coaxially. The outer side in the axial direction is heated by a heating hand 25 such as a burner, and the inner periphery 2 1 A of the outer tube forming raw material tube 2 and the curved portion of the inner tube forming raw material tube 20 are welded. 3 a 2 0 A, thereby obtaining a discharge vessel Η having a double tube structure in which the tubular discharge space s is formed between the outer tube J 2 and the inner tube 13. Here, the inner tube 20 for forming the raw material tube 20 is a curved portion that is continuous to the central area portion if the thickness of the central area portion is 3 ′. As the thickness toward the outer end becomes larger, the outer end portion of the joint portion becomes larger. The thickness is t3. In the case of heating and melting the raw material tube 21 for forming the outer tube and the raw material tube 20 for forming the inner tube, from the viewpoint of uniformizing the heat capacity of the heating section 加热 heated by the heating means 25, the raw material for forming the inner tube of the heating portion η is heated. The length L of the tube is preferably 100% or more of the thickness t1 of the material tube for forming the outer tube. As a result, at the end of the side of the configuration where the raw material tube 2 for the side tube configuration and the raw material for the inner tube configuration are oriented, and at the side t2 for the split 2 1 and the outer 20, -12- 200540905 (9) uniform heating state is obtained. In the state of 'can be fused. Moreover, an appropriate discharge gas is enclosed in the discharge space s of the discharge vessel 11 obtained as described above, and the external electrodes 15 and the internal electrodes 16 are arranged at predetermined positions. 10 of the excimer lights. In this way, when the outer tube 12 and the inner tube 13 are heated and fused at both ends according to the excimer lamp 10 configured as described above, φ is heated by the heating means 25. The thickness t1 of the outer tube forming raw material tube 21 is approximately the same as the thickness t3 of the curved portion 1 3 A of the inner tube forming raw material tube 20. The outer tube forming raw material tube 2 1 and The heat capacity of the inner tube structure raw material tube 20 is approximately equal, and uniform melting and heating are applied. Therefore, deformation or distortion can be reliably suppressed, and a stable and firm joining state can be obtained. As a result, the outer tube 12 and the The joint portion of the inner tube 13 has a sufficiently high reliability structure. Therefore, when the Φ excimer lamp 10 is transported or installed, or at the initial stage of lighting, the discharge vessel 11 can be reliably prevented from being damaged. In the foregoing, it has been described that a discharge vessel having a structure having a thickness greater than the thickness of the inner pipe than an inner pipe is provided, but a discharge vessel having a structure having a greater thickness than the thickness of the outer pipe The same effect can be obtained by those who have completed. In particular, the present invention is a constitution in which the thickness of the thinner of the outer tube and the inner tube is 0.5 to 1.0 mm, and the thickness of the thicker is 1.5 times or more the thickness of the thinner. For example, the excimer lamp 1 〇-13- 200540905 (10) A component with a total length of 100 mm or more is extremely useful, and the joint between the outer tube and the inner tube can be made with sufficiently high reliability.

A raw material tube 30, a double tube structure formed by joining two end portions with a joining member 35 made of the same material as the raw material tube 31 for the outer tube construction and the raw material tube 30 for the inner tube construction, such as quartz glass. . In this embodiment, the thickness 11 of the outer tube configuration raw material tube 31 is made larger than the thickness 12 of the inner tube configuration raw material ® tube 30 (11-1 · 5 X12). The joining member 35 is a substantially short cylindrical shape having a bent portion 36 which is bent so as to extend and extend outward in the radial direction at one end portion, and a straight tubular portion 37 which is continuous with the segment portion through the bent portion 36; and The thickness of the end portion of the curved portion 36 of the outer wall constituting the end portion of the curved portion 36 constituting the outer tube by joining the raw material tube 31 is approximately the same as the thickness of the outer tube constituting raw material tube 31, and is approximately the same as that of the inner tube. The thickness 15 of the end portion of the straight tubular portion 37 to which the raw material tube 30 is joined is made approximately the same as the thickness t2 of the raw material tube 30 for the inner tube configuration. -14- 200540905 (11) That is, the thickness difference between the thickness of the end of the curved portion 3 6 and the thickness of the outer tube constituting raw material tube 31 | t〗 _t4 | to create the thickness t of the outer tube constituting raw material tube 31 〖Or the thickness of the end portion of the curved portion 3 6 is less than 20% of the thickness t4, and the thickness of the end portion of the straight tubular portion 37 is different from the thickness of the raw material tube 30 for the inner tube thickness | 11 -15 | The thickness t2 of the inner tube constituting raw material tube 30 or 20% or less of the thickness t5 of the end portion of the straight tubular portion 37 is t5. φ The excimer lamp configured in this way is the same as in the case shown in Fig. 1 when the straight tube-shaped outer tube is welded from the outer side of the tube axis by heating such as a burner. The inner peripheral surface 3 1 of 3 1 and the front end surface 3 6 a of the curved portion 3 6 of the joint member 3 5 are welded from the inner side of the radial direction by heating such as a burner or the like. The outer end surface 30A of 30 and the front end surface 37A of the straight tubular portion 37 of the joint member 35 can obtain a discharge vessel with a double tube structure in which a tubular discharge space is formed between the outer tube and the inner tube. From the viewpoint of uniformizing the heat capacity of the heating portion Η 1 when the raw material pipe 31 and the joining member 35 are connected to the outer pipe structure, the heating portion of the outer pipe forming raw material pipe 31 and the joining member 35 is obtained. The length L 1 of the joint member η1 is preferably 100% or more of the thickness t1 of the raw tube 31 for the outer tube configuration. Also, 'when joining the joining member 35 and the inner tube constituting raw material tube 3 0', from the viewpoint of obtaining a uniform heat capacity of the heating portion H2, the "inner tube constituting raw material tube 30 and the joining member 35 are heated. The length L2A of the joining member 35 of the portion H2 and the inner tube structure of the heating portion H2 -15-200540905 (12) The length L2B of the raw material tube 30 to be used is preferably the same size. The length L2 A of the joining member 35 of the heating portion H2 and the length L2B of the inner tube forming raw material tube 30 of the heating portion H2 are not particularly limited. For example, as the inner tube forming raw material tube 30, the thickness t2 Over 100% of the size. In this way, in a state where the uniformly heated state is obtained, the raw material tube 31 for the outer tube configuration and the bonding member 35, and the raw material tube 30 for the φ inner tube configuration can be fusion-bonded. As described above, the description has been made of a discharge vessel having a configuration in which the thickness of the outer tube is larger than the thickness of the inner tube. However, the thickness of the outer tube 11 is made smaller than the thickness t2 of the inner tube. The situation is the same (ti X 1 · 5 S t2). That is, as shown in FIG. 4, as the joining member 45, a curved portion 46 that is joined to the end wall to form the end wall is joined to the outer tube forming raw material tube 41, and the thickness t 6 at the end portion is used as the outer tube forming raw material tube. The thickness t1 of 1 is approximately the same size, and the thickness t5 of the end portion of the straight tubular portion 47 joined to the inner tube forming raw material tube 40 is approximately the same as the thickness t2 of the inner tube forming raw material tube 40. The inner peripheral surface 4 1 A of the outer tube forming raw material tube 4 1 and the front end surface 4 6 A of the bent portion 4 6 of the joining member 45 are welded together, and the outer end surface of the inner tube forming raw material tube 40 is welded at the same time. 4 0 A and the front end surface 4 7 A of the straight tubular portion 47 of the bonding member 4 5, thereby obtaining a double-structure discharge vessel having a tubular discharge space formed between the outer tube and the inner tube. When joining the outer tube constituting raw material tube 41 and the joining member 45, from the viewpoint of obtaining a uniform heat capacity of the heating portion Η 1, -16-200540905 (13) The outer B constituting raw material tube 4 and the joint The length L 3 of the interface member 45 of the heating portion of the component & 5 is preferably 100% or more of the thickness u of the outer tube forming raw material tube 41 of the heating portion H1. Also, "when joining the joining member 45 and the raw material tube for the inner tube configuration", from the viewpoint of obtaining a uniform heat capacity of the heating portion H2, the raw material tube 40 for the inner tube configuration and the heating portion φ H2 of the joining member 45 The length L4A of the joining member 45 and the length L4B of the inner tube forming raw material tube 40 of the heating portion H2 are preferably the same size. The length L4A of the joining member 45 of the heating portion H2 and the length L4B of the inner tube forming raw material tube 40 of the heating portion H2 are not particularly limited. For example, as the thickness of the inner tube forming raw material tube 40, t2 1 0 0% Above the size. As a result, in a state where the uniform heating state is obtained, the raw material tube 41 for the side tube configuration and the bonding member 45, and the raw material tube 40 for the inner tube configuration 40 can be fusion-bonded. As described above, according to the present invention, the stimulated quasi-separated lamp formed by the discharge tube and the discharge tube formed by joining the outer tube and the inner tube at both ends by additional connection members is formed by directly welding the outer tube and the inner tube. Similarly to the excimer lamp of the first embodiment, the raw material tube 31 (4 1) and the outer tube of the heating portion H1 of the joining member 3 5 (4 5) are constituted by the outer tube constituting the raw material tube 41 and the outer tube constituting the raw material tube 31 (4 1) and The thickness of the joining member 3 5 (4 5) is approximately the same, and the joining member 3 5 (45) and the heating pipe H 2 of the inner tube forming material pipe 3 0 (40) are joined with the joining member 3 5 (45) and the inner side. The outer and zygotic states of the 40-point structured structure of the H1 structure 3 1 are made of the material side -17- 200540905 (14) The thickness of the raw material tube 3 0 (40) is about the same size, so that the heating part Η 1, The heat capacity of the two members of H2 becomes approximately equal, so that the two members can be evenly heated. Therefore, deformation or skew can be reliably suppressed, and a stable and firm joint can be obtained. As a result, the outer tube and the inner can be connected. The joint of the tube is made to have a sufficiently high By constitutive 'can therefore be handled by or 10:00, or excimer lamp lighting initial installation' can be reliably prevented from breakage of the discharge vessel 11. φ or more 'describes the embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be applied. For example, in the excimer lamp of the first embodiment, as a raw material tube for outer tube construction, both ends of which have curved portions that are processed to extend inward in the radial direction, the thickness of the tip portion of the curved portion and The thickness of the raw material tube for the inner tube is approximately the same. As the raw material tube for the inner tube configuration, a straight tube having a uniform thickness in the direction of the tube axis is used. The raw material tube for the outer tube configuration and the raw material tube for the inner tube configuration are used. A constitution in which a discharge vessel is formed by φ fusion bonding may be used. Further, in the excimer lamp of the second embodiment, the bonding member is not necessarily the same as the material of the outer tube and the inner tube, and for example, synthetic quartz glass, fused silica glass, and ultraviolet-resistant glass materials can be used. Successor. In addition, the excimer lamp of the present invention has a compartment wall that protrudes outward in the radial direction from the outer peripheral surface of the inner tube of the discharge vessel at one end side in the discharge vessel so as to extend fully across the entire circumference of the inner tube circumference. Formed, and thus, an absorption capacity for adsorbing impure gas such as oxygen, hydrogen, carbon monoxide, or water, which is connected to the discharge space between the partition wall and the end wall of the discharge vessel can be formed. Constructor with auxiliary space. As shown in FIG. 5, in such a structure, the partition wall is a disk-shaped partition wall constituting member 60 formed of glass, and the straight tube is welded to the joining member 55 forming a part of the inner pipe. The thickness t6 of the partition wall constituting member 60 of the heating portion is formed on the outer peripheral surface of the portion 57. The thickness t6 is preferably approximately the same as the thickness 15 of the straight portion 57. That is, the thickness difference between the thickness of the straight tubular portion 57 of the g-joint member 55 and the thickness of the partition wall constituting member 60 is I t5-t6 |.

As a result, the heat capacity of the joining member in the heating portion becomes approximately the same as that of the partition wall constituting member 60, and the joining member 55 and the partition wall constituting member 60 can be fusion-bonded in a state in which a uniform heating state is obtained. In addition, the magnitude d of the separation distance between the end face position of the partition wall constituent member 60 and the end face position of the straight member 5 7 is, for example, the thickness 12 of the inner tube constituting raw material tube 40, which is 1 to 100.

The part can obtain a stable and firmly joined state. The thickness t4 of the outer end portion of the bent portion 56 is joined to the outer tube forming raw material tube 41 of the joining member 55, which is approximately equal to the thickness t 丨 of the outer tube forming raw material tube 4 丨. The structure of the gas-tipped tube t6 55 is larger than that of the tube-like tube. 19- 200540905 (16) Also, as shown in FIG. 6, the excimer lamp of the second embodiment is used as a joint.

The inner peripheral part of the tube forming raw material tube 40 for the fusion welding (the opening edge part of the inner tube forming raw material tube fitting hole) 6 8 has a thickness of t 8 and the thickness of the inner tube forming raw material tube 40 is approximately 12 The same size. That is, the thickness difference between the thickness of the outer tube constituting raw material tube 41 and the thickness of the outer peripheral portion 67 of the outer tube constituting raw material tube 41 is tl_t7 |, and the thickness of the outer tube constituting raw material tube 41 is 11 or the outer circumference. The thickness of the edge portion 67 is less than 20% of the thickness t7, and the thickness difference between the thickness of the inner tube forming raw material tube 40 and the thickness of the inner peripheral portion 68 | t2-t8 | The thickness t2 or the thickness t 8 of the inner peripheral portion 6 8 is less than or equal to 20 ° / 〇. The size (radial direction length) of the outer peripheral edge portion 67 of the joining member 65 is formed from the viewpoint of uniformizing the heat capacity of the joining portion of the joining member 65 and the outer tube constituting raw material tube 41, and the outer tube is formed. The size of the thickness 11 of the raw material tube 41 for the construction is more than 100% of the thickness 11, and the size of the inner peripheral portion 68 of the joining member 65 (the length in the radial direction • 20-200540905 (17)) is obtained from the joining. From the viewpoint of uniformizing the heat capacity of the joint portion of the member 65 and the inner tube forming raw material tube 40, a size of 100% or more of the thickness t2 of the inner tube forming raw material tube 40 is made smaller than that of the physical operation (Example) Hereinafter, an embodiment of the excimer lamp of the present invention will be specifically described, but the present invention is not limited to this.
