Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of manufacturing a fluorescent lamp for emitting light in the ultraviolet field. [Prior Art] Recently, ultraviolet light having a wavelength of about 300 nm has been utilized in photocatalyst or generalized resin hardening, sterilization, therapy, and the like. In the light source of the light, a fluorescent violet which is coated on the inner surface of the arc tube with a phosphor having a peak intensity of 250 to 80 nm is used. In the fluorescent lamp emitting ultraviolet light as described above, the ultraviolet light of a shorter wavelength (for example, lower) which is excited by the phosphor by discharge is irradiated to the phosphor to make 1 The radiation is obtained by converting the ultraviolet 3 body layer and the light-emitting tube obtained by converting the light into a predetermined wavelength region, in principle, the same as obtaining 3. In the case of an arc tube of a fluorescent lamp, it is generally suitable for a so-called hard glass such as a value, a borosilicate glass or an aluminosilicate glass. However, in a violet fluorescent lamp having a wavelength of, for example, a wavelength of about 250 to 380 nm, when the hard glass is used in an arc tube, absorption of ultraviolet rays is formed so that the ultraviolet light transmittance is low and the thickness is thin. For the glass of the light-emitting tube, it is preferable to use ultraviolet light. The beauty of the fluorescent lamp, the doctor's eye with the external line as above is obtained by using 2 0 Onm to excite the light and to pass through the fluorescent light. See the light phase. Sodium glass External light radiation Because of the poor light. The rate is higher -5 - 201009883 Therefore, in view of the above, a fluorescent lamp using quartz glass in an arc tube has been disclosed, for example, in Patent Documents 1, 2 and the like. As shown in the technique described in the above documents, if quartz crystal glass is used for the arc tube, the transmittance of ultraviolet light can be made high, and light can be efficiently extracted. (Patent Document 1) Japanese Laid-Open Patent Publication No. 2008-503046 (Patent Document 2) Japanese Laid-Open Patent Publication No. 2007-534128 (Draft of the Invention) _ (Problems to be Solved by the Invention) However, in general, in a fluorescent lamp, In the manufacturing process, there is a process of heating the phosphor to a temperature near the softening point of the glass constituting the base material of the arc tube. However, since the softening point of the quartz glass is around 160 °C, when it is heated to a high temperature region as described above, there is a problem that the phosphor is deteriorated and predetermined light cannot be obtained. In view of this, when the firing temperature of the phosphor is lowered to a temperature in a temperature region where the luminescent properties are not problematic, for example, 900 ° C or lower, e is formed, and the softening of the quartz glass is not obtained. The body layer is peeled off by the tube wall and falls, and a predetermined light distribution is not obtained. Therefore, an object of the present invention is to provide a fluorescent lamp having high ultraviolet transmittance and high efficiency by providing quartz glass in an arc tube in a fluorescent lamp that emits ultraviolet rays, and there is no peeling of the phosphor. High-reliability fluorescent lamps, such as falling, etc. (Means for Solving the Problem) -6 - 201009883 Therefore, the fluorescent lamp of the present invention is a fluorescent lamp that emits ultraviolet rays, and is characterized by comprising: an arc tube made of quartz glass; and a softening point lower than that of quartz glass a glass layer formed on a surface of the discharge tube side of the light-emitting tube; and a phosphor layer formed on the surface of the glass layer by excitation to emit ultraviolet light. Further, the glass layer may contain any of borosilicate glass and aluminosilicate glass. Further, it is preferred that the glass layer has an average thickness of from 1 to 30 μm. Further, a method for producing a fluorescent lamp of the present invention is a method for producing a fluorescent lamp that emits ultraviolet rays, characterized in that a layer of glass having a softening point lower than that of quartz glass is formed in advance in a tube made of quartz glass. A suspension of a fluorescene phosphor in which a phosphor and a binder are mixed is applied onto the layer of the glass, and the phosphor is fired. Further, the glass having a lower softening point than the quartz glass may include any of borosilicate glass and aluminosilicate glass. (Effect of the Invention) The fluorescent lamp of the present invention has a glass layer formed of a glass having a softening point lower than a softening point of quartz glass between the quartz glass light-emitting tube and the phosphor layer. When the phosphor is heated to a temperature of 1000 ° C or higher, it can be fired to form a fluorescent lamp having less deterioration of the phosphor and having a good conversion efficiency with respect to ultraviolet -7-201009883 light, and is interposed between the phosphor layer and the phosphor layer. Since the glass between the arc tubes is softened, the combination of the phosphor layer and the arc tube can be made stronger, and the fluorescent lamp can be formed without peeling off the phosphor layer and falling off without illuminance unevenness. . Further, since the arc tube is made of quartz glass, a fluorescent lamp having excellent ultraviolet light transmittance and high ultraviolet light emission efficiency can be obtained. Then, the glass layer contains glass of at least one of borosilicate glass (Si-B-lanthanum glass) and aluminosilicate glass (Si-Al-lanthanum glass), and the heat-resistant squeezing property is good, so It is very resistant to temperature changes when used as a fluorescent lamp, and does not cause problems such as peeling of the glass layer or a decrease in bonding with the phosphor layer, and can reliably maintain the phosphor layer. Further, since the average thickness of the glass layer is 1 to 30 μm, the phosphor layer can be surely held, and a fluorescent lamp which is excellent in loss of transparency and ultraviolet light transmittance can be formed. Further, according to the method for producing a fluorescent lamp of the present invention, a glass layer composed of glass having a softening point lower than a softening point of quartz glass is formed between a quartz glass light-emitting tube and a phosphor layer, and then an egg light is formed. Since the body layer is formed, the firing temperature of the phosphor can be set to be relatively low, and the fluorescent lamp having less deterioration of the egg light body and good conversion efficiency to ultraviolet light can be formed, and since the glass is softened, the phosphor layer is made soft. The combination with the arc tube becomes stronger. It can be formed as a fluorescent lamp in which the phosphor layer is not peeled off or peeled off, and illuminance unevenness does not occur. As a result, it is possible to easily and surely obtain a fluorescent lamp in which the arc tube is made of quartz glass and which has excellent ultraviolet light transmittance and high ultraviolet light emission efficiency. -8 - 201009883 [Embodiment] [Embodiment 1] An embodiment of the present invention will be described with reference to Figs. 1 to 4 . Fig. 1 is a flow chart showing the manufacturing process of the fluorescent lamp, Fig. 2 is a glass tube as a material for the arc tube of the lamp, and Fig. 3 is a view showing the manufacturing process of the arc tube is perpendicular to the tube axis.

As can be seen from Fig. 2 to Fig. 4, the arc tube 11 of the fluorescent lamp of the first embodiment has the inner tube 11 1 and the outer tube 112 arranged substantially coaxially, and the end portions ua are respectively packaged. In the case of 11B, a cylindrical discharge space S is formed inside. Further, in the present embodiment, the arc tube 11 is made of a glass tube 80 made of fused silica glass. Hereinafter, a method of manufacturing a fluorescent lamp of the present invention will be described with reference to Figs. 2 to 4 in accordance with the flow chart of Fig. 1. Φ 1 - A slurry in which a glass powder constituting a glass layer is dispersed (Step 1) is produced. The bulk glass for constituting the glass layer is finely pulverized and applied to a ball mill. The pulverized glass powder is spread on a sieve to thereby classify the particle diameter to prepare a glass powder having an average particle diameter of 0.5 to 10 μm (preferably 1 to 5 μπ 。. The glass powder and nitrocellulose ( The nitrocellulose and the butyl acetate solution are mixed at a weight ratio of 1: 4. The mixture is placed in a ball mill together with an alumina ball to be fully honed to prepare a slurry in which the glass powder is dispersed in 201009883. The powder-dispersed slurry is referred to as a "glass slurry." The glass constituting the glass layer has a glass having a lower softening point than the softening point (1600 ° C) of the quartz glass as the base material of the arc tube. The glass in the range of the firing temperature of the phosphor (400 to 900 ° C) is preferably a hard glass having good heat resistance and punchability. - Among them, borosilicate glass (Si-Β-lanthanum glass, softening point: Aluminium silicate glass (Si-Al-lanthanum glass, softening point: about 900 ° C) is preferable, and the hard glass shown above may be used singly or in an appropriate ratio. 2. Next, apply the glass paste to the hair The inner surface of the glass tube for the light pipe is formed (step 2). In the present embodiment, the glass tube 80 for the light-emitting tube is provided with the inner tube so that the discharge space has a cylindrical shape as shown in Fig. 2 The outer tube 82 and the outer tube 82 are formed with exhaust pipes 83A and 83B that communicate with the outside at both ends in the longitudinal direction of the glass tube 80 for light-emitting tube formation (hereinafter, simply referred to as "glass tube 80"). The glass tube 80 for illuminating the light-emitting tube is vertically held, and one of the exhaust pipes is placed, for example, 83B on the liquid level of the container filled with the glass paste, and one of the exhaust pipes 83A is sucked to suck the glass slurry. The glass slurry is filled inside the glass tube 80, and then extracted by the other exhaust pipe 83B. The thickness of the finally obtained glass layer can be changed by adjusting the viscosity or the number of coatings of the glass violet. The thickness of the glass paste is preferably in the range of 1 to 30 μm. Among them, since the higher transmittance is obtained for the predetermined ultraviolet light, the thickness of the glass layer-10-201009883 is maintained in the post-engineering process. Camp light body The range is as small as possible. 3. The glass paste is dried (step 3). One of the exhaust pipes 83A of the glass tube 80 for the light-emitting tube is caused to flow dry nitrogen gas toward the other exhaust pipe 83B. The butyl acetate contained in the glass paste is evaporated. As a result, it is formed on the inner surface of the glass tube 80. A layer having a glass powder having a thickness of 1 to 30 μm deposited may be used. Dry the air 4. Heat the glass tube to heat the layer of the glass powder (Step 4).

When the above borosilicate glass or aluminosilicate glass is used, it is preferably carried out at a temperature of from 600 to 990 °C. By the firing process, the particles are combined with the gemstone and fused to the glass tube, and the glass layer is strongly consolidated on the substrate. However, since the glass layer does not rise to the melting temperature, the φ is generally maintained in a powder form, but may be formed in a state in which the temperature is further increased and melted. 5 - The glass tube is cooled to a normal temperature (step 5), and the slurry of the prepared phosphor is applied to the arc tube by a suction method (step 6).

These egg light systems absorb ultraviolet light in a region that does not reach a wavelength of 25 〇 nm, and convert it into ultraviolet rays in the central wavelength region, respectively, and emit the light. @ 6. Splashes the water from the phosphor paste and dries it (step 7). The one of the exhaust pipe 83A of the glass tube 80 for the light-emitting tube is caused to flow dry nitrogen gas toward the other exhaust pipe 83B, thereby evaporating the butyl acetate contained in the phosphor slurry. The gas used for drying may also be dry air. 7. Burn the phosphor (step 8). The light-emitting tube was placed in a furnace with a glass tube and fired. The firing conditions are about 500 to 800 ° C in an atmospheric environment, and the temperature is maintained at the highest temperature for 2 to 1 hour. In this firing process, glass softening occurs at the interface between the phosphor layer @ and the glass layer, and the phosphor is adhered to the glass layer, and as a result, a strong bonding state is obtained. As a result, as shown in Fig. 3, a glass layer 14 composed of a low-softening point glass powder and a phosphor layer are sequentially laminated on the inner surface of the glass tube 80 for the arc tube formed of quartz glass. The state of 15. In the case where the phosphor which is highly deteriorated in the atmosphere is heated to a temperature at which the nitrocellulose is burned in the atmosphere, it can be formed into a non-oxidizing atmosphere or a reducing atmosphere to be about 80 degrees. Degree of heating. -12- 201009883 8. Cool the glass tube to normal temperature (step 9), seal the inside of the glass tube with a rare gas and seal it in a gastight manner (step 1). More specifically, after the phosphor layer 15 and the glass layer 14 adhering to the inner surfaces of the exhaust pipes 83A and 83B are removed, one of the exhaust pipes 83 is heat-sealed and discharged by the other exhaust pipe 83. The gas is sealed with a predetermined rare gas (enclosure) for tip-off. As a result, - the fluorescent φ lamp arc tube 11 in which the cylindrical airtight discharge space S is formed as shown in Fig. 4 is obtained. The rare gas to be enclosed is, for example, xenon (Xe), krypton (Kr) 'argon (Ar), or neon (Ne), and they may be used singly or in combination. The wavelength system obtained by the discharge of the rare gases is 160-190 nm, chlorine 124, 140-160 nm, ammonia l7-1065 nm, and gas 80-90 nm. 9. Next, the inner peripheral surface of the inner tube is disposed. The inner electrode is provided with an outer electrode along the outer peripheral surface of the outer tube (step 1 1 ). The arc tube 11 obtained in the step 10 is provided with a pair of external electrodes composed of the inner electrode 12 and the Φ outer electrode 13 to complete the excimer lamp 10. The inner electrode 12 is disposed such that, for example, two metal plates of a cross-sectional C-shape are disposed opposite each other along the inner circumferential surface of the inner tube 1 1 1 . The outer electrode 13 is composed of, for example, a mesh electrode, and is disposed to cover the entire outer surface of the outer tube 1 1 2 . The fluorescent lamp described above is a position in which a pair of electrodes are located outside the discharge space, but is not limited to the above example, and may be applied to, for example, at least one of the electrodes is disposed inside. If the electrode is placed in the discharge space, the electrode can be mounted before the LED tube sealing process (step 8) -13- 201009883. The specific dimensions of the final product of the fluorescent lamp obtained as described above are listed as follows. The total length of the arc tube (1 1 ) is about 30,000 to 2,000 mm, the wall thickness of the inner tube (111) is 1-2 mm, and the wall thickness of the outer tube (112) is 2 to 3 mm. Further, the average thickness of the phosphor layer (15) is: 1 〇 2 〇 μπι ' a glass layer composed of a low-softening point glass formed between the phosphor layer (14) and the arc tube (1 1 ) (14) Thickness: 1~3 0μιη. In the fluorescent lamp shown in Fig. 4, the inner electrode 12 and the outer electrode 13 are arranged to face each other in a state in which the inner tube U1, the outer tube 1 1 2 and the discharge space S are interposed. When the inner electrode 1 2 and the outer electrode 13 are connected to the lead wires W11 and W12, the power supply device 16 is connected, and when a high-frequency voltage is applied from the power supply device 16, the dielectric is interposed between the electrodes 12 and 13 ( The discharge is formed by 111, 112, etc., and ultraviolet light having a wavelength of 17 2 nm is generated by light emission of, for example, xenon (Xe) which is a discharge gas. In the luminescence for excitation of the ultraviolet light-based phosphor obtained here, since the ultraviolet light having a wavelength of 172 nm is irradiated to the phosphor layer, the phosphor is excited. For example, the type of the phosphor is selected, and the ultraviolet light having a wavelength of 250 to 380 nm is emitted. . The ultraviolet light having a wavelength of 250 to 380 nm thus obtained is sequentially transmitted through the phosphor layer 15, the glass layer 14, the arc tube 1 1 and the outer electrode 13 (void portion) to be radiated to the outer glass layer 14 by ultraviolet light transmittance. It is worse than quartz glass, but the thickness of the layer 14 may be at most 30 μm or less. Therefore, the ultraviolet light having a wavelength of 2 5 0 to 3 80 nm is less absorbed, and most of it is transmitted and radiated to the outside of 201009883. As a result, ultraviolet light of a desired wavelength region can be emitted with a particularly high efficiency as compared with the case where the light-emitting tube is formed of glass having a low softening point. Among them, the vacuum ultraviolet light having a wavelength of 17 2 nm generated by the discharge of helium gas is used in the 20 Onm level at the absorption end of the borosilicate glass or the aluminosilicate glass in the glass layer, and is almost impermeable. Therefore, the unnecessary short-wavelength - ultraviolet light is not radiated to the outside. The embodiments of the present invention are described below, but the present invention is not limited to the following. [Example 1] <Preparation of glass slurry; > Boric acid glass (Si-antimony-based glass) and aluminosilicate glass (Si-A1-0-based glass) were mixed at a ratio of 1:1.

The borosilicate glass powder is mixed in a ratio of 1:4 by weight in a mixture of butyl acetate and nitrocellulose. The liquid is additionally applied to a ball mill and stirred to prepare a slurry in which the glass powder is dispersed. The slurry in which the glass powder is dispersed is referred to as "glass slurry". <Rare gas fluorescent lamp Production> Using the glass paste crucible, an external electrode type rare gas fluorescent lamp (20) having the shape shown in Fig. 5 was produced, wherein the figure (a) was cut perpendicularly to the tube axis.

In the case of the slurry liquid, a rare gas fluorescent lamp of Comparative Example 2-1 was produced by producing a rare gas fluorescent lamp in the same manner as in Example 2 except that the phosphor paste was applied to the quartz glass tube. Among them, -18-201009883, the firing condition of the phosphor was heated at 600 ° C for 1 hour. [Comparative Example 2-2] In the case where the above-mentioned glass slurry liquid solution was not used, the phosphor paste was directly applied to the quartz, and the firing conditions of the phosphor were formed for 1 hour, and the examples were 2 The comparative rare gas fluorescent lamp was produced in the same manner. In the first and second embodiments described above, it is directed to the use of xenon gas (which is a discharge gas, which is obtained by the discharge of a dielectric substance, and which is obtained by the discharge of a dielectric substance, and is converted into a region of 300 nm or more by a phosphor. The present invention is not limited to the gas fluorescent lamp, and may be applied to a low-pressure mercury lamp. Hereinafter, an example will be described. [Example 3] Next, an example was produced according to the configuration of Fig. 6 a low-pressure mercury fluorescent lamp of the type 3. The glass tube constituting the light-emitting tube is fused silica glass. The glass paste obtained by the method of the above embodiment 1 is coated in the inside of the tube by a suction method. A, after drying, after firing at 700 ° C, the phosphor is used to modulate the fluorescence using the S BE, and the phosphor paste is applied by suction and natural drop in the same manner as described above. After the phosphor paste is dried, the glass tube is fired at 500 00 for 1 hour, and the glass tube is 1 0 0 0 °c: Example 2-2 Xe) is used as a wavelength of 177 nm, and the same one hour body is used for internal electricity. The slurry method is carried out, whereby the -19-201009883 will be equipped. The glass tube of the end tube is a filament structure (32, 33) obtained by active treatment of three pairs of carbonate after it is attached to the solid body. A low-pressure mercury fluorescent lamp shown in Fig. 6 was finally obtained by sealing a rare gas of argon 4 kPa 4 (30 T rrrr) and mercury 10 mg/cm 3 inside the glass tube. In the present embodiment, mercury is used as the *discharge material, and thus ultraviolet rays of a wavelength region such as 185 nm, 254 nm, and 320-3 70 nm are obtained. However, in the low-pressure mercury lamp of the third embodiment, the energy of the wavelengths of @185ΠΠ1 and 254 nm occupies most of the radiation, and therefore the emission of light of the order of 300 nm cannot be expected too much. When a light having a wavelength of 185 nm and a wavelength of 254 nm is converted into light having a wavelength of 300 nm by using a phosphor, the wavelength can be particularly efficiently emitted compared to light having a wavelength of about 320 to 70 nm which is usually obtained only by mercury discharge. 300nm light. Here, the configuration of the low-pressure mercury fluorescent lamp will be described with reference to Fig. 6 . In the present embodiment, the arc tube 31 has an outer diameter φ ΐ Omm, an inner diameter ❹ Φ 8.8 mm (wall thickness 0_6 mm), and a total length of 1200 mm. The internal electrodes 32 and 33 formed of a filament structure are supported by the sealing members 37 and 38 so as to be opposed to the arc tube 31. The pin electrodes W31 and W32 are connected to the internal electrodes 32 and 33, and are connected to a predetermined power supply device (not shown). The average thickness of the glass layer 34 and the phosphor layer formed on the inner surface of the arc tube 31 is ΙΟμπα and 15 μm, respectively. -20-201009883 [Comparative Example 3 -1] The inside of Comparative Example 3-1 was produced in the same manner as in Example 3 except that the phosphor slurry was directly applied to the quartz glass tube without using the glass slurry. Electrode type fluorescent lamp. Here, the firing conditions of the phosphor were heated at 700 ° C for the same time as in Example 3 for 1 hour. [Comparative Example 3 - 2 ] Φ The phosphor paste was directly applied to a quartz glass tube without using a glass slurry, and the firing temperature of the phosphor was set to 100 (TC, 1 hour, except In the same manner as in Example 3, an internal electrode type fluorescent lamp of Comparative Example 3-1 was produced. [Experimental Example 1] The lamp was turned on by using a lighting power source suitable for each fluorescent lamp to measure the light. Ultraviolet illuminance. The ultraviolet illuminance uses a spectroscope ('USR40' manufactured by 9 USHIO Inc.) and is placed at the center of the length of the lamp. That is, the receiver is placed at a position 20 mm away from the wall of the tube. The ultraviolet illuminance of the fluorescent lamps of Examples 1, 2, and 3 was set to 1 〇〇, and the ultraviolet illuminance of the lamp of the comparative example was shown with respect to 値. The result is shown in the "UV illuminance" column in Table 1. [Experimental Example 2] In addition, the fluorescent lamps of the above-described Examples 1 to 3 and the fluorescent lamps of Comparative Examples 1-1 to 3-2 were evaluated for the adhesion of the phosphor. The phosphor layer was densely covered 201009883. The evaluation of the connection is made when the lamp is dropped from 5cm on the wooden board. Drop: X, part of peeling: △, completely unpeeled: 〇 to be evaluated. The results are shown in the “Adhesiveness” column in Table 1.

In the lamps of Comparative Examples I·, 2-1, and 3-1, since the glass layer was not provided, the ultraviolet light transmittance was better than that of the lamp of the example, but the adhesion of the phosphor layer was inferior. The result of peeling and falling also occurs in the lighting of the lamp, and there is a case where the expected illumination is not obtained. On the other hand, in the lamps of Comparative Examples 2-2 and 3-2 in which the firing temperature was set to be near the softening point of the quartz glass, the adhesion to the phosphor layer was sufficient, but the fluorescence was not obtained. The excited state of the body, as a result, does not obtain the desired ultraviolet light, but forms a lamp with the lowest ultraviolet illuminance. Among them, the lamps of Comparative Example 1-2 -22-201009883 were set at a lower temperature of 80 ° C than the other Comparative Examples 2-2 and 3-2, so that the adhesion of the phosphor was also poor. The above embodiments are merely examples of the implementation of the invention, and may of course be appropriately modified. For example, in the above embodiment, SBE - (Sr-B-0 : Eu ) , LAM ( La-Mg-Al-0 : Ce) , LAP : Pr, . Gd ( La-P-0 ) are used separately. Examples of Gd and Pr) are described as phosphors. However, in the lamps of the respective embodiments of φ, any of the phosphors may be used, or the phosphors may be mixed in an appropriate ratio. Use it. Of course, other phosphors may be used if the wavelength of the emitted light and the converted ultraviolet light are appropriate, and is not limited to the above.
