A discharge gas 14 is sealed inside the glass tube bulb 101. When a voltage is applied to the external electrode 13A, the discharge gas enclosed in the glass tube bulb 1〇1 generates a discharge phenomenon. The solder layer 12 is disposed between the external electrode 130 and the glass tube bulb 101, and the external electrode 130 is fixed to the glass tube bulb 101. The disc layer 107 formed on the inner surface of the glass tube bulb 101 is concentrated, and the ultraviolet light radiated from the mercury vapor contained in the discharge gas 140 can be converted into visible light. The phosphor layer 107 contains a red radiation phosphor, a green radiation phosphor, and a blue radiation phosphor to emit white light. The red radiation phosphor contains oxidized in B. 铕 (Υ 203: Eu), the green radiant filler contains 填 镧 钸: 钸, test (Lap 〇 4 : Ce ' Tb) and blue radiation phosphor contains BaMg2Al16 〇27 : Ειι and its analogues. ^, the desired scale layer 107 should have a thickness of 3 microns (μηι) or more, 50 microns to 200924014 107; ^^, ϋ 5 microns or more, and 3Q microns or less. If the filler layer is filled with light, then f, the photo-deposit layer 107 can be spalled off; and if the i method produces a sufficient amount of radiation. Only mixed 4 shots are pre-determined ratio f mercury vapor with rare gas gas at a predetermined pressure (1·3χ10 to 40x103 Pa (five) to 3 Torr)) Rare gas: ί in the empty part of bulb 101 Discharge medium. For example, a gas mixture of helium and helium. The mixing ratio of rare gases is the gas of i? An argon gas having a weight percentage of five and a weight of ninety percent of the tri-methanol vapor are irradiated with ultraviolet light to excite the phosphor layer 107. The glass tube bulb 101 is a straight length of 960 mm (coffee) and has an inner tube diameter of only 20 mm or more and a 5-tube bulb with a diameter of less than 2.0 mm, and is interposed between the external electrodes 13 〇〇t The resistance becomes larger 'make the external electrode hot. On the other hand, if the inner diameter of the glass & light bulb 101 is larger than 5 mm, the illuminance becomes insufficient. , ίί = thinner, with a glass tube lamp with an inner diameter greater than 5.0 mm ^ = suitable. As a material for the liquid crystal display device. Therefore, according to this embodiment, the inner diameter of the official electric light bulb 101 is set to 3 mm. Preferably, the glass tube bulb 101 should have a thickness of more than 3 mm and less than 丨〇. If the thickness of the glass tube bulb 101 is set to less than 0.3 mm, the pinhole may be formed in the glass tube bulb 1〇1, whereas if the thickness of the glass tube bulb is set to be larger than the filament, the external electrode 13〇 The resistance between the glass tube bulbs is a soft glass having a high dielectric constant. The soft glass of each of the constants has a dielectric constant of \8 at 1 to 5 billion hertz (GHz), and is suitable as a material for the external electrode type glory hi. The soft and high dielectric glass contains Si〇2, Na2Q, BaQ, ZnC), M, =, Nb205, Sb203 and Bi2〇3. As shown in Fig. 3A, the external electrode 130 has a conductive layer 132 formed of a sheet-like conductive material, and a preventive oxide layer 133 formed over the conductive layer 132. Formed under the conductive layer l32 in 200924014 as the affinity layer m, the affinity layer 131 is modified and provides an affinity between the buffer layer 120 and the external electrode 13〇. The wettability of the force W can be used as the conductive layer 132 as a material having a thermal expansion coefficient with the material of the vessel 1 (1). =1 — The ray-return _ number is approximately 93xl (r7/t, == 'swell A (four) equals 7GxlG_7/°C and less than or equal to 12GxlQ.yc & The surface of the material selected as the conductive layer 132 is carbon-doped, and __健介ϋ ΧΚ5ΧΚ) /C ' is therefore suitable as the material of the conductive layer 132. In the swell coefficient, the temperature is between (TC to 30 (the thermal expansion coefficient of rc, I ^ thermal coefficient becomes less than 70X10-Vc or greater than 120xl (m: when 2 == U system == becomes larger, so _ tube power_1 () 1 other + outside, due to the inclusion of nickel and / or chromium stainless steel sus 403 and Sl ^ 4 = eight have a coefficient of thermal expansion (10) and allow 101xl () -7 / c ^, = The material of the conductive layer 132. In this non-ferrous steel, the amount of Tt, 2G% or less of nickel and weight percentage = two H 疋 weight f% 0% nickel and less than tens of thousands of chromium, or baige ratio 20 Less than % nickel and 5% by weight of chromium. The thickness of a conductive layer 132 must be only 〇.〇5 mm to 0.2 mm. If the conductivity is α2 mm thick, the external electrode type glory should preferably be The thickness μ of the conductive layer 132 = 133 is an oxidation of the metal forging layer 132 covering the upper surface of the conductive layer 132. The thickness of the preventive oxide layer 133 is set to 0.2 4 m ^ 0.4 μm is preferable. If the thickness of the oxidation preventing layer 133 is prevented from being set, the oxidation preventing ability is insufficient; on the other hand, if the thickness of the protective oxide layer 133 is not more than 0.4 μm The film will be cracked, etc. 200924014 The anti-oxidation layer 133 is made of purity 99% or higher pure ====, but steel, tin, zinc and the like can be substituted for the shape and shape.嫂 Silver film 'Affinity layer (3) thick (four) η, (4) Hidden pole i3G has a five-layer structure, which can be set by sequentially laminating r-weld layer 133, conductive layer 132, prevention oxide layer m and circle, shape of external electrode 130 On the peripheral surface of the glass tube bulb 1 母1, the bust portion. The external electrodes 130 are electrically insulated from each other. = The oxide layer (10), for example, purely tilted, is formed in the glass just opposite to the drain 130 The inner surface of the bulb 1〇1 is used to suppress the chemical reaction between the mercury and the glass material in the bulb κη. Therefore, the discoloration of the glass bulb 101 is stopped. 丨 [The manufacturing method of the fluorescent lamp] will be described The manufacturing method of the external electrode type fluorescent lamp 111. Μ The commercially available _ hollow glass is poured into the previously determined length, = glass (four) off the table to close the pure water and the like, and the temperature is about C to the glass tube to divide The system has an age-based gift, etc. The flushing, fire, and roasting procedures can be used. The inner surface of the glass tube is clean. The red, green and blue radiation-filled particles of the Wei agent layer 107 are prepared to disperse when dispersing the medium (the phosphorescent fluid is divided into its analogs as a sub-section. It can also be included in it. 'Fat, Epoxy, Cage resin and the like can make the composition of the binder. If the binder component remains in the product of the illuminating lamp, it will be mixed. 5Influencing the service life ( After the coating fluid is dispersed, the glass tube bulb 1Q1 should be co-baked to evaporate the binder component, such as durability), luminosity (brightness), and the like. The oxidized (Υ2〇3) particles constituting the protective layer 103 in the medium are dispersed in a dispersion medium to prepare a fluid dispersion (protective layer fluid dispersion). 200924014 八私 η ' The phosphor layer fluid and the protective layer fluid are separately dispersed on the surface of the glass tube bulb 1〇1 by spraying m, soaking and the like. Thereafter, the glass tube bulb iqi is baked to evaporate the binder component in the scale layer & body dispersion and protective layer fluid dispersion. In the step of receiving ~I, the mercury and the rare gas are sealed in the glass tube bulb 101, and then - * 匕 seal. Thereafter, the external electrode 130 is mounted on the peripheral surface of the glass bulb 101 facing the protective layer 103. A conductive paste 13 = ί ϊ solder paste (which will be the solder layer 12G) is coated on the conductive material 101 to be coated on the surface of the sheet. The gold ore layer (affinity layer 131) is formed on one side of the conductive layer 132), while the nickel layer (preventing the oxide layer 133) is t-shaped on the other side of the V-electrode material. Therefore, the surface of the solder paste provides good wettability.曰1·31
