These fluorescent lamps are made by injecting gas and mercury after discharging the gas inside the glass tube for a fluorescent lamp, and then sealing it by sealing it to a certain size. Namely, the fluorescent lamp is packaged with a certain amount of I gas and 2 silver in a state where a phosphor is coated inside the glass tube, and two electrodes are provided inside or outside both ends of the sealing glass tube. The k-light body acts to excite ultraviolet light, making the ultraviolet light into visible light. That is, when a high voltage is applied to the two electrodes, a discharge is generated inside the glass tube due to the emission of electrons, and electrons collide with the mercury atoms to generate ultraviolet rays, and the ultraviolet phase-emitting phosphor becomes visible %. Therefore, the phosphor is a structural element that has a significant influence on the performance and driving efficiency of the fluorescent lamp. Fig. 6 is a sequence of a conventional method of applying a phosphor to the inside of a glass tube. First, a phosphor is applied to the inner wall of the glass tube, and the process includes the steps of: applying a pretreatment solution (si〇i) to the inner wall of the glass tube, and applying a phosphor (S10) to the solution layer. Then: the sealing portion...the electrode forming portion of the tube is divided into two: broken: (S105). At this point, use a brush to wipe off the fluorescing 200822173 body on the inner wall of _ , g . In this way, during the process of removing the phosphor by the brush, the layer of the solution is also removed. Therefore, the pretreatment solution (s 107 ) is applied again on the inner wall of the glass tube sealing portion and the electrode arrangement portion. Then, the pretreatment solution (s丨〇9) coated on the glass tube seal portion was removed by a brush. That is, the glass tube sealing portion and the electrode arrangement 4 are provided in this order from the both ends of the glass. The pretreatment solution of the glass tube sealing portion needs to be completely removed, and the electrode arrangement portion needs to retain the pretreatment solution in order to prevent mercury reduction or the like. The purpose of removing the pretreatment solution of the glass seal is to improve the sealing effect, and also to prevent the occurrence of micropores of foreign matter during the sealing of the glass tube, resulting in a shortened life of the fluorescent lamp. The conventional method of applying a phosphor to the inside of a glass tube is to be reapplied to the electrode portion of the pretreatment solution which is wiped off by the brush. Therefore, the process is increased, thereby reducing the production efficiency.

[Embodiment] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a flow chart for explaining an embodiment of the present invention. Fig. 1 shows, in order, a method of coating a phosphor of a fluorescent lamp. In the fluorescent lamp phosphor coating method of the present invention, first, a pretreatment solution is applied to the inner wall of the glass tube 1, and a pretreatment solution layer (S1) is formed, and then the coating portion of the glass tube 1 is removed by an isopropyl alcohol solution. The solution layer (S3) is pretreated, and then a phosphor (S5) is applied to the inner wall of the glass tube, and then the phosphor coated on the glass tube sealing portion and the electrode arrangement portion is removed by a butyl acetate solution (S7). 2 is a perspective view showing an external structure of a fluorescent lamp in an embodiment of the present invention, FIG. 3 is a schematic diagram of a device 200822173 to which a coating method according to an embodiment of the present invention is applicable, and FIG. 4 is a VI-VI of the device shown in FIG. Line cutaway view. As shown in Fig. 2, the fluorescent lamp 1 includes a tube portion u, a sealing portion 1b, and an electrode arrangement portion ic = a tube portion 1a is located at an intermediate portion of the glass tube and is a portion through which light is transmitted. The dense portion lb is a portion that seals the end portion of the tubular body portion 1a in order to form a vacuum state inside the tubular portion U. The electrode arrangement portion 丨c is a portion where the external electrode is formed after the glass tube is sealed. This fluorescent lamp is coated with a phosphor inside. When a high voltage is applied to the two electrodes, the flowing electrons generated by the discharge collide with the mercury atoms in the glass tube to generate ultraviolet rays, and the ultraviolet rays irradiate the phosphors into visible light. Next, a device for applying the phosphor to the inside of a glass tube will be briefly described. As shown in FIG. 3 and FIG. 4, the device for coating the phosphor inside the glass tube comprises: a base 1〇1, a moving plate 103 disposed above the base ιοί, at a distance from the base; the moving plate lifting device 105, which is combined with the base 1〇1 and the moving plate 103; the loading box 107, which is combined with the moving plate 1〇3, can carry a plurality of glass tubes; the vacuum generating device i 09 is used for being inserted in A negative pressure is generated in the glass tube of the loading cartridge 107; and a solution supply device m for storing the solution. The moving plate 1〇3 can be raised or lowered by the lifting device 1〇5. The lifting device 105 may be a conventional structure including a hydraulic cylinder or an air cylinder, a screw shaft, or the like. A loading case 107' for inserting a glass tube is provided with holes for forcibly inserting and fixing the glass tube on the upper and lower sides thereof. The loading cassette 107 can typically be loaded with 100 or 2 glass tubes at the same time. The agricultural storage box 1 〇 7 fixes the glass tube to the moving plate 1 〇 3 in an upright state. Therefore, the moving plate 103 moves up and down, and the loading cassette 107 also moves up and down. The loading cassette 107 is connected to the vacuum generating device 1〇9, and a vacuum generating device 109 is used to generate a negative pressure inside the glass tube. Further, a solution supply device ln is provided below the loading cassette 107. According to the above respective steps, the solvent of the pretreatment solution, the solvent of the pretreatment solution, the phosphor, and the phosphor are separately contained in the container of the solution supply device 以η. Moreover, the means for applying a phosphor inside the glass tube further comprises: a bubble generator 113 for generating bubbles in the solution supply device ;; and/or an ultrasonic generator 115 for use in the solution supply device Ln produces ultrasonic vibration. The bubble generator 1 13 and/or the ultrasonic generator 5 generate bubbles and/or ultrasonic waves in the container of the solution supply device 1 1 1 to make the pretreatment solution layer and the phosphor easier to remove. The device according to the embodiment of the present invention can immerse a large number of glass tubes in a solvent, thereby coating a phosphor or removing a partial coating of a phosphor or the like at the official end of the glass, to illustrate that a large amount of glass can be easily The structure in which the tube is impregnated in a solvent. The present invention is not limited to the apparatus for applying a phosphor to the inside of a glass tube according to the present embodiment, and can be implemented by various means. In order to explain the embodiment of the present invention, Fig. 5 sequentially illustrates the step of applying a phosphor inside the glass tube. Next, the phosphor coating method of the fluorescent lamp of the present invention will be described with reference to Figs. 1 and 5(a) to Fig. 5(d). As shown in Fig. 5 (a), a ruthenium treatment solution is first applied to the entire inner surface of the glass tube 1 to form a pretreatment solution layer 3 (S 1 ). The solution used to form the pretreatment > valley liquid layer 3 can block the ultraviolet rays generated inside the fluorescent lamp from being transmitted to the outside or prevent the mercury inside the fluorescent lamp from being reduced. Further, the pretreatment solution layer 3 contributes to an increase in the cohesive force of the phosphor and also serves to enhance the coating ability of the phosphor. The pretreatment solution may be a conventionally known substance known as 9 200822173, optionally using isopropanol _ ^ ^ ^ ^ 4 / gluten. Of course, the solvent of the pretreatment solution, 1 = the characteristics of the bath, may be selected from different solvents. As mentioned above, ★—When the pre-treatment solution is applied on the surface, a large number of glass (4) officials 1 are shown in the erect state), and the glass, the mountain ί loading box 107 (Immersed in the head 3 and Figure 4) In the container containing the pre-treatment solution, the glass tube is evacuated by the vacuum generating device 109, so that the Jt (four) privately becomes a negative pressure state, thereby making the front Luoxin glass 5 1 is internally moved and applied to the inner wall of the glass tube 1. The present invention (4) is not limited to the embodiment described herein, and any technique that can apply a pretreatment solution inside the glass tube can be used. In the step S1 of applying the pretreatment solution to the inner wall of the glass tube, the pretreatment solution layer 3 is formed in the tube body including the glass tube i::, the glass tube sealing portion lb, and the electrode arrangement portion u. Secondly, as shown in Fig. 5(b), the glass tube seal portion of the glass tube i is broken in the solvent used in the pretreatment solution, for example, in the isopropyl alcohol solution 'two removal coating on the glass tube seal Pre-treatment solution layer on section lb 3 ° at this time 'if using gas The generator U3 or the ultrasonic generator generates bubbles or ultrasonic waves in the Lok solution, which can be removed more easily: the solution layer is processed. In addition, because the glass tube seal portion ib is the portion that needs to be sealed in the subsequent work, the glass is sealed. It is preferable not to dispose of the tube i: any foreign matter. The pretreatment solution applied to the glass tube seal lb is removed: the purpose of preventing the occurrence of defective products due to foreign matter in the subsequent sealing process. Moreover, the removal is applied to the glass tube seal. Another reason for the pretreatment solution layer 200822173 of the portion lb is to prevent the occurrence of micropores in the sealing portion due to foreign matter, thereby shortening the life of the fluorescent lamp, and finally improving the quality of the fluorescent lamp. Further, the front of the electrode arrangement portion lc The treatment solution layer 3 is preferably left as it is because the pretreatment solution layer prevents the mercury reduction inside the fluorescent lamp due to the voltage applied to the external electrodes 11, 13 (shown in Fig. 2) of the glass tube.

The phosphor 15 can use a conventional phosphor. When a high voltage is applied to the two electrodes, the flowing electrons generated by the discharge collide with the mercury atoms in the cracker to generate ultraviolet rays, and the ultraviolet light irradiates the phosphor into visible light. The phosphor 15 can be applied to the inner wall of the glass tube by the same or a similar process as the step of applying the pre-treatment solution. In this process, the phosphor 15 is applied to the entire inner wall of the glass tube, that is, the entire inner wall of the glass tube including the glass tube sealing portion and the electrode arrangement portion lc. Finally, as shown in Fig. 5(4) As shown in the figure, the glass tube sealing portion and the electrode arrangement portion lc of the glass f! are immersed in a phosphor solvent, for example, a solution of acid butyl vinegar: and thus a fluorescent iridium 15 (S7). The glass tube sealing portion is a portion that needs to be sealed in the post-f process, and therefore, the glass tube 1 does not have any foreign matter remaining on the glass tube 1. Further, it is preferable that the electrode arrangement portion u retains the front portion to prevent the phosphor from being deteriorated by heat, and since it is also formed as the electrodes 11, 13', it is preferable not to leave the phosphor. In the case of Fig. 5 (d), the state in which the glass tube sealing portion 1b and the electrode arrangement portion lc body 15 are removed is the same as the solution for applying the phosphor to the inside of the glass tube. That is, the pretreatment solution 11 200822173 = and the glory 15 on the glass tube sealing portion 1b are removed, and the electrode arrangement is ~ the phosphor 15 while leaving the pretreatment solution 屛, removing the virtual tread, 6, 6 or 6 This is because the solvent used before: Γ 3 and the solvent used for coating the phosphor 1 S, the pretreatment solution layer 3 on the electrode arrangement portion k is obtained [that is, the solvent for dissolving the phosphor) It is preferable to select, 厣, 女, 女, 解 / 处理 : : : : : : : : : 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心 心The same, the description will not be repeated here. According to the present invention, the step of re-recording the pretreatment solution layer 3 by the main portion 1G can be omitted. Therefore, the coating method involved in the monthly application can reduce the coating work of the fluorescent lamp = further increase the production cost by reducing equipment costs and saving raw materials. In particular, the present invention is practiced in comparison with the prior art method of removing a portion of a pretreatment solution layer or a glory body using one or more glass bulbs by using a brush: by using a solvent, a large amount of the carrier carried on the loading cassette can be simultaneously processed. Glass & therefore, further increase production efficiency.
