Field of the Invention The present invention relates to an electrode preparation body before being assembled in a lamp, and a lamp, a backlight module, a liquid crystal display device, and an electrode preparation having the electrode assembly of the present invention as an electrode The manufacturing method of the body. [Background Art 3] In the electrode preparation body of the electrode of the cold cathode type lamp, one end of the member for a guide bar is adhered to the bottom of the electrode member having a bottomed cylindrical shape by the laser 10 being melted. In the welding, as shown in Fig. 12(a), the bottom portion 901a of the electrode member 901 having the bottomed cylindrical shape is in contact with the end surface 9〇3a of the rod member 903 (the abutting portion is formed). The welding predetermined portion is irradiated with a laser beam to the bottom portion 9〇1a of the electrode member 901 corresponding to the predetermined portion of the welded portion 15. Specifically, the laser beam is irradiated to the bottom portion 901a (arrow 图 in the figure) of the electrode member 901 from the opening side of the electrode member 901 in the straight direction with respect to the bottom portion 901a of the electrode member 9A1 (for example, Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. 2003-272520. In the case where the electrode member 901 and the member for the guide bar are adhered by laser welding as described above, the strength of the electrode member 9〇1 is weakened. Specifically, as a result of the vibration test of the δ 'electrode preparation, as shown in Fig. 12 (8), the (4) part (bottom 9Gla) has a crack 9G5 (Fig. 12 (4) 200921743 indicates a state diagram before welding, and for convenience Use Figure 12 (a)). Fig. 12 (8) is a view showing the electrode preparation body having a crack at the bottom viewed from the direction of the arrow 第 in Fig. 12 (8). When the crack 905 of the bottom portion 901a is continuously formed into a five-circle shape as shown in Fig. 12(b), it is clear that the bottom portion 9〇1a of the electrode member 901 is outwardly displaced by the cylindrical portion 901b. Further, the electrode member 9〇1 of Fig. 12(0) shows a longitudinal sectional view, which should be shaded, but it is unclear because the crack 9〇6 is omitted. In the light of the above-described problems, it is an object of the present invention to provide an electrode member including an electrode preparation body in which an electrode preparation member is directly or indirectly adhered to a member for an electrode and a member for a guide bar. An electrode preparation body, a lamp, a backlight module liquid crystal display device 15 capable of improving the adhesion between the electrode member and the bar member, and a method of manufacturing the electrode preparation body capable of improving the adhesion. In order to achieve the above object, the electrode preparation member for a lamp for use in the electrode preparation system electrode member of the present invention and the member for a guide bar is adhered to each other, and is characterized in that the electrode member and the member for the guide bar are adhered to each other. In the above-described electrode member and the above-described bar member, at least one of the members is irregularly extended to the other member side, and the lamp electrode preparation body, the electrode member and the bar member are configured. The member for the welding member is bonded to the member for the welding rod, and is characterized in that the electrode member and the member for the rod member that penetrates the member for the welding member are configured to be the member for the electrode and the member for the rod. Among them, at least the structure in which the member member irregularly protrudes from the other member side of the 200921743, or the member for the lamp electrode preparation system electrode and the member for the guide bar are transmitted through the welding member and adhered by welding, The adhesive member is configured to pass through the adhesive member of the welding member and the adhesive member. Electrode rod member and said guide member with at least one member among irregularly protrude configuration. Here, the case where at least one member protrudes toward the other member 'of course, the other member also protrudes toward a member, and the "irregularly extended configuration" refers to the amount, size, shape, etc. of the members protruding from each other. One of them is a different 10 structure, or the shape of the interface between one member and another member is set to an irregular shape, and the protrusion to the other side after welding can be set as the member from the extended side. A continuous structure that continuously protrudes irregularly, or a separate structure (independent island structure or co-continuous structure, etc.) that is extended to separate from the member itself. 15 It is possible to experimentally confirm the improvement of the adhesion strength between the extended body member and the other member on the extended side by the above-mentioned projecting structure. Further, it is characterized in that the electrode member has an end wall at one end of the cylindrical shape, and the extension of the other member to the end wall does not reach the surface opposite to the side of the end wall of the electrode member. Therefore, for example, the adhesion portion of the end wall and the interface become wider as compared with the case where the projection of the other member toward the end wall reaches the side opposite to the adhesion side of the end wall of the electrode member. The strength in the end wall of the electrode member after welding can be improved. Moreover, the alloy region is susceptible to sputtering due to electrons in the discharge space, and the exit p-knife is & 5 and the extension portion is adhered to the end wall of the electrode member 7 200921743 on the opposite side (inner side) In the case where the extended and scattered alloy is attached to the glomerate layer, the decrease in the degree of twist and the unevenness of the color β are caused by the member of the member (the fourth embodiment) Since the adhesive side is on the opposite side, it is not easy to receive the front. Here, the "member in the case where the member is directly adhered" is described as being used for the electrode member and the member for guiding the rod and the rod for penetration: for the guide rod The member 'electrode member melting member and the guide bar Γ Γ (4) lion (four) shape, then 10 15 20 The right side of the present invention, the light touch and liquid crystal display device has the above electrode preparation body as the electrode 具High strength electrode. Therefore, in a state in which the electrode and the guide bar are provided and the manufactured article of the present invention is in contact with each other, the structure of the electrode is replaced with the structure of the guide bar =: the electrode member for the electrode and the guide bar are used: In part, the wire-shaped member and the front "turning structure η", at least the structure in which the member is irregularly extended toward the other member side, and the original original cost (four) line of the aforementioned laser miscellaneous, and, in the manufacture of The method of manufacturing the laser body by the laser welding device is characterized in that the electrode member is formed by the above-mentioned __ member. And a material portion of the guide member, wherein at least one of the member for the front electrode and the member for the guide member is irregularly protruded toward the other member side, and the original structure is locally rotated. In the manufacturing method of the present invention, the manufacturing method of the present invention is a method of manufacturing a lamp electrode preparation body by laser welding in a state in which the electrode member and the bar member are brought into contact by the welding member. Method, characterized by constituting the aforementioned fusion The member is irregularly extended to the at least one member side of the member for the electrode and the member for the guide bar, and the laser welding is performed by maintaining the structure locally. According to these methods, the adhesive portion is irregularly extended, and the adhesion is improved by the test.

The crucible electrode preparation bodies 33 and 35 are sealed in the glass tube 31 2〇 by the sealing bodies 48 and 5G. Further, the seal bodies 48 and 50 are made of a material whose linear expansion coefficient is close to that of the glass tube 31. For example, mercury and a rare gas (e.g., argon, helium) and the like are filled in a predetermined amount in the discharge space 40 formed inside the glass tube 31 which has been filled at both ends. Further, the rare gas system is sealed in a reduced pressure state. 11 200921743 The transverse cross-sectional shape of the glass tube 31 is, for example, a circular shape, and a glory layer 43 is formed on the inner surface thereof. As the material of the glass tube 31, for example, lead-free glass - Ba〇-A1203 - Na20 + K20-Ce 〇 2) can be used. Further, in this case, it is preferable to select a glass having a coefficient of expansion similar to that of the glass tube 31 as the above-mentioned seal bodies 5 48, 50. Further, as the material of the glass member 31, a material other than the lead-free glass may be borosilicate glass (si〇2 - b2o3 - Al2?3 - κ2? - Ti?2). In this case, the material of the seal body under 10 15 can also be a glass tube (for example, Bead glass) having the same expansion coefficient as the glass tube. In the glass tube 31, the inner diameter is 丨4 [m is more than 7.0 [mm] or less, and the thickness is 〇.2 [mm] or more and [6 [mm] or less. However, the present invention is not limited to the size. . The phosphor 43 includes, for example, each of the three-wavelength type phosphors. For the three-wavelength type phosphor, for example, a rare earth-based phosphor is used. Here, it is explained that yttrium oxide [Y203: Eu3+] (abbreviation: YOX) is activated by red light emission, and green light is activated to activate yttrium phosphate [LaP04: Ce3+, Tb3+] (abbreviation: LAP) and blue luminescence activate strontium aluminate [BaMg2Al16〇27: Eu2+] (abbreviation: BAM-B), and [A B] will be described in the following paragraphs). It can be seen from Fig. 3 that the phosphor layer 43 is formed not only on the inner surface of the glass tube 31 corresponding between the pair of electrodes 45, 47, but also in the slave electrode in order to set the effective light emission length to the longest length. The outer circumferences of the cylinder portions 45b and 47b of 45 and 47 face the inner surface of the cylindrical tube (the inner side of the cylindrical portion 45b, 47b (the center side of the discharge space), and the outer side (the outer surface of the bottom portion 45a, 47a). A part or all of the phosphor crystal layer 43 is present between the inner side and the outer side of the tubular portions 45b and 47b at each end in the tube axis direction. 12 200921743 4·Electrode structure (electrode preparation) Electrode structure The bodies 33, 35 (corresponding to the electrode of the present invention) include, for example, bottomed electrodes 45, 47, and guide bars 49, 5 indirectly adhered to the bottom portions 45a, 47a of the electrodes 45, 47, and adhered to the guide bars 49. The external lead wires 53 and 55 of the present embodiment include the external lead wires 53 and 55. However, the external lead wires may not be included. The electrodes 45 and 47 are of a so-called cold cathode type. By the tubular portions 45b, 47b, at the bottom of one end of the cylinders 45b, 47b (equivalent In the "end wall" of the present invention, 45a' 47a is formed. Further, the 'electrode structure 33, % is called a member that seals 10 15 20 to the end portions 31a, 31b of the glass & 31, and the electrode preparation body means The other member of the glass s 31 is sealed, that is, the member before being assembled in the glass (four). In this embodiment, the recording material is used as the electrodes 45, 47, respectively, and the iron/recorded alloy (FeNl) is used as the guide bar. 49 and 5, manganese and recorded alloy (MnNi) are used as the external introduction line 53 and %. Further, in the case where lead-free glass is used as the glass tube 31, the guide bars 49 and 51 are made of an alloy of iron and nickel, for example, (4) When the glass is replaced by a glass tube η, for example, iron-cobalt-nickel alloy (Ni-Co-Fe), molybdenum, and tungsten can be used. The adhesion between the electrode 45 47 and the guide bars 49 and 51 is by laser melting ( ). That is, the electrodes 45, 47 are transmitted through the subsequent sections 57'59 and (4) to the guide bars 49, 51. The state of "adhesive adhesion" is constructed to constitute the adhesion of the electrodes 45, 47 and the guide bars 49, 51.卩"(包读鹤料)' contains the area of the components constituting the electrodes 45, 47 to >: - and the components constituting the guide bars 49, 51 At least one of the two regions, such as at least one of the knives, is a structure that protrudes regularly from the other member side 13 (the following is simply referred to as "extended structure"). The constituent electrodes 45, 47 are included. The two regions in which at least one component of the component and the region constituting at least one of the components of the guide bars 49 and 51 are irregularly extended are also referred to as "external structure". Further, in the case where the electrodes 45 and 47 are adhered to the external charge-introducing lines 53, 55, for example, the resistors are welded, and the electrodes 45 and 47 and the guide bars 49 and 51 are adhered through the fusion-bonding members 57 and 59, The "adhesive portions of the electrodes 45, 47 and the guide bars 49, 51" also contain a molten material. 10 5_Method of Manufacturing Electrode Preparation FIG. 4 is a view for explaining a method of manufacturing an electrode preparation body. The electrode preparation body 61 is an electrode member 63 for constituting the electrodes 45 and 47 of the electrode structures 33 and 35, a welding member 69 for constituting the bonding materials 57 and 59, and a guide bar for constituting the guide bar 49. The member 65 and the lead-in wires for constituting the external lead wires 53 and 55 of the electrode preparation bodies 33 and 35 are adhered in the order of the structure. Eight bodies and σ, the bottom portion 63a of the electrode member 63 and the end face 6 of the guide bar member 65 (4) are connected to the member 69, and in this state, as shown in Fig. 4 (4) and (8), The refining member is still about the center in the longitudinal direction and is inclined to a predetermined angle M from the side of the bar member 65 toward the outer periphery of the transfer member 69 with respect to the line segment A orthogonal to the knowledge of the bar member Μ. And the laser is irradiated about the center of the length direction. The target position to be illuminated by the laser is placed at equal intervals in the circumferential direction of the splicing member 69 (the majority of the position of the phantom (depending on the complexity of the cost and position adjustment, here are three 14 200921743 ^ temporary coffee) According to the well-known technique, the member 69 is used to perform the welding of the electrode member 63 and the rod member 65 in the form of welding. The arch is sorrowful ί \ Here, the temporary connection is made. For example, it is necessary to use a material having a lower melting point of the electrode member 6 than the member for the electrode rod as the material for the melting member 69, for example, under the electric resistance. The electrode member 63 and the material for the guide bar have a small volume. This is because the operability at the time of welding (ease of melting) can be improved and the heat capacity (high efficiency) can be lowered. 10 Figure 5 shows the case where the electrode preparation body is manufactured. A diagram showing the relationship between the power intensity of the laser and the irradiation time. The intensity of the laser power of the irradiation is such that the electrode member 63 and the adhesive portion of the rod member 65 are not melted by air to form a uniform alloy layer (no formation is formed). The strength of the layer, that is, the adhesive portion of the electrode member 63 and the guide member 15 is set such that at least one of the members of the electrode member 63 and the member for the guide member 65 is irregularly directed to the other member. The structure of the member protruding, and

亦即，本實施樣態之電極預備體61製造時之雷射功率 強度，較習知之電極預備體901的雷射功率強度低。此乃因 以習知之功率強度來熔接電極用構件與導棒用構件時，則 10 該黏者部分會形成電極用構件與導棒用構件的合金’而無 法熔接成具有伸出的構造之故。換言之，於黏著之不規則 地伸出的構造為形成電極用構件與導棒用構件（與熔接用 構件）之均一的合金(層）之前的階段，能而以較形成合金之 功率強度低的雷射來照射而獲得。 15 又，電極用構件與、引棒用構件及熔接用構件之各材 料與上述材料不同時，各構件之融點也不同，當然雷射功 率強度與照射時間也可能在上述範圍之外。 依據上述製造方法，熔接後之導棒用構件65之一端部 分(65a)、熔接後之電極用構件63之底部63a、而且熔接用構 20 件69所形成之黏著部分呈（相互）不規則地伸出的構造。 又，此不規則地伸出的部分，該部分的溫度原原本本

又，此雷射加工的條件與照射位置為一例，當然，一 10 旦電極用構件61等材料、尺寸改變，則其條件也會改變。 又，可得知於樣式1及樣式2，電極用構件61、熔接用構件 69、導棒用構件65之材料、尺寸相同，雷射加工的條件與 照射位置相同，但是，其伸出構造相互不同。 (2)習知品 15 第10圖係說明使用於拉伸強度試驗之習知品的圖式。 以習知方法製造之電極預備體(稱為習知品）9 21與發明

電極預備體61相對於以習知方法製作之電極預備體921，可 以說電極用構件63與導棒用構件65之黏著強度約提昇了 1.5倍。 此乃因具有電極用構件63與導棒用構件65之黏著部分 28 200921743 相互不規則伸出的構造，而伸出之構造之區域内的合金區 域面積擴大，因此提昇了黏著強度。 以上，依據實施樣態說明了本發明，然而，本發明當 然不限於上述之樣態，例如也可設成以下的樣態。 5 1.電極預備體 (1) 關於有無熔接用構件 實施樣態中，在電極用構件與導棒用構件之熔接上，係透 過熔接用構件而間接地黏著，但是，也可將電極用構件與 導棒用構件直接黏著，於此情形下，也可看出電極用構件 10 與導棒用構件之黏著部分如實施樣態所說明之不規則伸出 的構造’而能提南電極用構件與導棒用構件之黏著強度。 (2) 關於形狀 實施樣態之電極用構件的形狀為有底筒狀，亦即設成

構件有必要具有藉雷射等加熱而伸出的融點。具體而言， 兩構件之融點的差在500[°C]以下的範圍，而為了有更好的 29 200921743 伸出，前述融點之差最好是在100[°C]以下的範圍。 第11圖係以钥構成導棒用構件時之元素分布的概略 圖。 本例子之電極預備體101係由鎳所構成之電極用構件 5 103、以銦構成之導棒用構件105、配置於電極用構件103與 導棒用構件105之間且用以結合兩者的熔接用構件107所構 成。又，熔接用構件107以鈷構成。 此電極預備體101於透過熔接用構件107而熔接之電極 用構件103與導棒用構件105之黏著部分，包含構成熔接用 10 構件107之所有成分的區域（以第11圖之符號「L3」表示）構 成朝向導棒用構件105側伸出的構造。 又，於黏著部分，包含構成熔接用構件107之所有成分 的區域（以第11圖之符號「R3」表示）、構成電極用構件103 之成分之中至少一種成分及包含構成熔接用構件10 7之分 15 成之中之至少一種成分的區域（以第11圖之符號「K3」表 示），構成朝向電極用構件103側不規則地伸出構造。 表示電極用構件103與合金區域K3之交界的線段13如 第11圖所示，設成不規則的形狀，又，電極用構件103與熔 接用構件107之相互伸出，於來自電極用構件103之伸出區 20 域（圖中的符號「L3」）與來自熔接用構件107之伸出區域（圖 中的符號「R3」）之兩區域中，伸出量、伸出寬度、形狀及 伸出的區域數不同，而形成不規則的伸出構造。 如此一來，於黏著部分具有不規則的伸出構造，因此 提昇黏著部分的黏著強度。 30 200921743 (4)關於熔接 實施樣態中’說明了使用雷射作為㈣方法的情形， 然而，祇要是可將電極用構件與導棒用構件之黏著部分(也

As shown in Fig. 5, in order to prevent the adhesive portion from forming a uniform alloy layer (region), the power intensity of the laser is lowered. In this case, the irradiation time becomes longer. Specifically, the power intensity of the laser to be irradiated is in a range of 2 [kW] or more and 5 [kW] or less, for example, 4.6 [k\V] 'the irradiation time is 4 [ms] or more and 20 [ms] or less. , for example, I5 [ms]. Here, the term "homogeneous alloy layer" is used to mean a region where the ratio of the elements to be formed in the member constituting the alloy is a portion of the alloy layer, for example, a period of 15 200921743, for example, elemental analysis by SEM At the time, the scope of the uniformity can be broken. Specifically, in the analysis profile obtained by the SEM at a magnification of 90 [times], when the region is 0.1 [mm2], the region in which the ratio of the elements in the region to be zoned is the same is a uniform alloy layer. 5 In the fifth diagram, the relationship between the irradiation power of the laser and the time when the electrode preparation body of the figure 10 is not produced is shown by the broken line. That is, the laser power intensity at the time of manufacture of the electrode preparation body 61 of the present embodiment is lower than that of the conventional electrode preparation body 901. When the electrode member and the member for the guide bar are welded by the conventional power intensity, the alloy portion of the electrode member and the member for the guide bar is formed in the adhesive portion, and the structure cannot be welded to have a protruding structure. . In other words, in the stage in which the irregularly extending structure of the adhesive is formed into a uniform alloy (layer) between the electrode member and the member for the guide bar (for the member for welding), the power intensity of the alloy can be made lower. Obtained by laser irradiation. Further, when the materials for the electrode member, the rod member, and the welding member are different from the above materials, the melting points of the members are also different. Of course, the laser power intensity and the irradiation time may be outside the above range. According to the above manufacturing method, the adhesive portion formed by one end portion (65a) of the welded rod member 65, the bottom portion 63a of the welded electrode member 63, and the welded structure member 69 is irregularly (mutually) Outstretched structure. Further, in the portion which is irregularly extended, the temperature of the portion is originally lowered locally, and an irregular concavo-convex shape is formed at the boundary of the electrode member after welding which will be described later (the member for the electrode member protrudes from the member side of the rod and The alloy region of the welding member and the rod member protrudes toward the electrode member side. 16 200921743 In the same manner, the boundary between the members for the guide bar after the welding is formed into irregular irregularities (the member for the guide bar protrudes toward the electrode member side, and the alloy region of the member for welding and the member for the guide bar is extended to the side of the member for the bar. Out). In other words, the shape of the boundary between the electrode members after the fusion is formed into a shape different from the contact surface of the welding member 5 before welding and the member for the guide bar, and the shape of the boundary between the members for the welding rod after welding. Forming a shape different from the abutting surface of the member for the guide bar before welding and the member for welding. 6. About the adhesive portion (1) pattern 1 10 Figure 6 Element distribution diagram of the welded portion of the longitudinal section of the electrode preparation body, 6(a) shows a region including 50% or more of the electrode member, and FIG. 6(b) shows a region including 50% or more of the component for welding, and FIG. 6(c) shows 50% of the component for the bar. In the above area, Fig. 6(d) shows the overlap, and Fig. 6 (4) to (4). Further, Fig. 7 is a drawing of Fig. 6 (4). 15 has been described above, however, the electrode member 63 is made of nickel, the rod member 65 is made of an alloy of nickel and iron, and the welding member 69 is made of iron-cobalt-nickel alloy (alloy of nickel, cobalt, and iron). . Therefore, the alloy region of the electrode member 63 and the welding member 69 ("Q1" in Fig. 7) is mainly composed of nickel constituting the electrode member 63, and the alloy of the rod member 65 and the welding member 2069. The region ("R1" in Fig. 7) is mainly composed of iron constituting the member for the guide bar 63. When the alloy regions Q1 and R1 are in this region, the ratio of the elements constituting the member of the alloy is constant regardless of the position in the alloy layer, and is a uniform alloy layer. 17 200921743 The state of the electrode pre_ is explained below using Fig. 7. In Fig. 7, the alloy layer of the bonding portion 65 to the right upper side and the D surface and the bonding member 69 are respectively formed at the boundary between the member alloy region R1 and the electrode member 63. The line segment indicates the boundary between the alloy region R1 and the guide member 65. In the line segment "J1", the line segments C1 - C1 are the abutting faces of the electrode member 63 and the splicing member 69 before the splicing, and the wire is thin - _ connected to the member 69. The contact surface of the electrode member 63 and the transfer member 69 with respect to the front is linear (phase #赠和~). The line segment of the boundary between the pure electrode member 63 and the alloy region ri is called In the figure, the line segment spanning the abutting surface of the electrode member 63 and the refining member of the splicing month > is set to a denier shape in the form of a Cl (a straddle). 15 that is, the region including at least one component (here, the brocade) constituting the component for the electrode member 63 extends beyond the line segment and has a wedge shape and an irregular shape extending toward the side of the rod member 65 (in the figure) The symbol "L1"), the alloy region Ri of the welding member 69 and the bar member 65, that is, the region including the component constituting the welding member 69 (here, cobalt), exceeds the line segment C1 to C. 1 is irregularly extended toward the electrode member 63 side (symbol "K1" in Fig. 20). The contact surface between the electrode member 63 and the welding member 69 before the fusion (corresponding to one of the line segments C1 to C1) The region including all the components constituting the electrode member 63 is extended beyond the line segment C1 - C1 of the abutting surface, and the boundary line L1 is non-linear, and the shape is not the same in a certain period 18 200921743 shape. Irregular shape. Further, a region (the symbol "K1" in the figure) which extends beyond C1 - C1 of the welding member 69 toward the electrode member 63 side is three here, and the front end of all the regions is extended with C1 - C1 The distance represented by the distance is not the same, and the gap between the junction of the extended area and the intersection of C1 - C1 (the distance on C1 - C1) indicates that the extension width is different, and the shape is also different. Thus, in a region extending beyond C1 - C1, the amount of protrusion, the width of the protrusion, the shape, and the like are different, and an irregular protruding structure is formed. In the same manner, the area (the symbol "L1" in the figure) in which C1 - C1 of the electrode member 63 protrudes toward the side of the welding member 69 10 is two here, and the area extending in the entire area is The interval between the intersection of junction II and Cl - C1 (the distance on C1 - C1) indicates that the extension width is different, and an irregular extension structure is formed. On the other hand, the electrode member 63 and the welding member 69 are extended to each other, and protruded from the electrode member 63 (symbol "L1" in the drawing) and the protruding portion from the welding member 69 (Fig. The two regions of the symbol "K1" are different in protrusion amount, extension width, shape, and the like, and form an irregular protruding structure. Further, the amount of protrusion of the electrode member 63 on the side of the guide member 65 is indicated by the symbol "F1" in Fig. 20 (in this example, only the line segments D1 - D1 coincide with each other), the member for welding 69 and the member for the guide rod The amount of protrusion on the side of the electrode member 63 of the alloy region R1 of 65 is the symbol "E1" in the figure (both projection amounts are based on the line segments C1 - C1). Further, the electrode member "the alloy _ with the welding member 69" is formed in the alloy region R1 of the welding rod member 65 and the portion of the alloy member R in the vicinity of the interface η of the electrode member 63. That is, this region is an alloy of the electrode member 63 'welding member 69 and the member for the guide bar. Similarly, the contact surface between the member 65 for the guide bar before welding and the member for refining 569 is linear (corresponding to the line segment D1 - D1), and the alloy region R1 of the member for welding 69 and the member for the bar 65 is used. At the boundary with the member for guide bar 65; the line segment of 1 is as shown in the figure, so as to span the line segment D1 - D1 indicating the abutting surface of the member for guide bar 65 before welding and the member for welding 69 (over the appearance) Set to an irregular shape. In other words, the 10-region beyond the line segment D1 - D1 including the component constituting the guide bar member 65 is irregularly extended toward the electrode member 63 side (symbol "M1" in the drawing), and the 'welding member 69 is The alloy region R1 of the guide bar member 65, that is, the region including the component constituting the welding member 69 and the component constituting the bar member 65, exceeds the line segment di - D1 and the guide bar member 65 side irregularly protrudes from the region (The symbol "N1" in the figure). Further, the amount of protrusion of the member for the guide bar toward the electrode member 63 is the symbol "G1" in the drawing, and the direction of the alloy region R1 of the welding member 69 and the member for the guide bar 65 toward the member for the guide bar 65 is The amount of the protrusion in the figure is "H1". The contact surface between the guide member 65 and the welding member 69 before welding (corresponding to a portion of the line segment D1 - D1) is changed by welding, and includes a region constituting the component of the member 20 for the guide bar 20, and exceeds the abutting surface. The line segment 〇1 £1)1 is extended, the boundary line J1 is not a straight line, and the shape is not the same shape in a certain period 0, and the region of the bonding member 69 that protrudes toward the guide bar member 65 (Fig. The symbol "N1" in the middle has different protrusion amount, extension width, shape, and the like, and 20 200921743 forms an irregular extension structure. On the other hand, the welding member 69 and the rod member 65 project from each other in the projecting region from the welding member 69 (the symbol "Ml j in the drawing" and the protruding portion from the member 65 for the rod. In the rain 5 region (symbol "Ml" in the figure), the amount of protrusion, the width of the extension, the shape, and the number of extended regions are different, and an irregular protruding structure is formed. Further, the structure to be extended is the two sides of the electrode member 63 side and the guide bar member 65 side, that is, the structure which protrudes from each other, but the present invention is as long as r is the electrode member 63 side and the guide. It is sufficient that the rod member 65 has at least one side extending from the side of the member 65. Further, as shown in Fig. 7, the adhesive portion of the present invention is disposed between the extending end of the alloy region R1 toward the electrode member 63 and the extending end of the alloy region R1 toward the extending member 65. Next, the amount of protrusion is specified. 15 The amount of protrusion F1 of the electrode member 63 after welding to the guide member 65 is about 0.20 [mm], and on the other hand, the alloy region ri is oriented toward the electrode (the amount of protrusion E1 on the member 63 side is 0.07 [ The amount of protrusion G1 of the electrode member 63 of the guide bar member 65 is about 0.07 [mm], and the amount of protrusion H1 of the alloy region R1 toward the side of the bar member 65 is 0.33 [mm]. In addition, the electrode member 63 and the rod member 65 before the welding of the electrode preparation body 61 shown in Fig. 6 have a bottom cylindrical electrode member 63 having a bottom thickness of 〇.2 [ Mm], the outer diameter of the tubular portion is 2 7 [mm], and the outer diameter of the member for the guide bar is 0.8 [mm]. Further, the thickness of the member for welding 69 is 〇2 [mm], and the outer diameter of the 21 200921743 is 0.8 [ Mm]. (2) Style 2 Fig. 8 is an elemental distribution diagram of the welded portion of the longitudinal section of the electrode preparation body. Fig. 8 (8) shows that the component of the electrode assembly contains 50% or more of the area, Fig. 8 ( b) The component of the component is not included in the region of 5q% or more. Fig. 8 (4) shows that the component of the bar member contains a region of 5Q% or more, and the exhaustion (4) does not overlap the Figs. 8(a) to (c). Fig. 9 is a drawing of Fig. 8 (4). 10 15 20 Here, the electrode member 63, the bar member 65, the welding member 69, the electrode member 63 of the pattern 1, the bar member 65, and The splicing member 69 has the same specifications (material and size), and the conditions of the lightning (four) are also the same. Therefore, the alloy region formed between the electrode member 63 and the welding member 69 ("Q2" in Fig. 9) The alloy region formed between the electrode member 63 and the bonding member 69 ("R2" in Fig. 9) also has the same composition as that of the pattern i. Hereinafter, the adhesion of the longitudinal section of the electrode preparation body will be described using Fig. 9. The state of the partial portion. The line segment of the guide member 65" indicates that the alloy region R2 with the member for the fusion member 69 is indicated by the hatching of the upper right side in the line "J2" in Fig. 9, respectively. The boundary between the alloy region R2 and the electrode member 63, and the segment indicates the boundary between the alloy region R2 and the rod member 65. Further, the line segments C2 - C2 are the abutting faces of the electrode member 63 and the welding member 69 before welding. , line segment D2 - D2 listening to the guide bar _ piece 65 and refining structure The abutting surface of the electrode member 63 and the welding member 69 before the fusion is linear (corresponding to the line segment C2-C2) ' _ after the alloy region 22 2221 21131 the junction of the electrode member 63 As shown in the figure, the line segment of π is formed in an irregular shape so as to span the line segment C2 - C2 indicating the abutting surface of the electrode member 63 before welding and the abutting surface of the welding member 69 (over the state). Into the spiral shape. 5, that is, the region including at least one component constituting the component for the electrode member 63 is beyond the line segments C2 - C2 and protrudes toward the rod member 65 in an irregular shape (symbol "L2a", rL2b" in the figure). Further, the alloy region R2 of the welding member 69 and the bar member 65, that is, the region including the cobalt constituting at least one component of the component for the welding member 69, exceeds the line segment C2 - C2 and 10 is irregularly oriented toward the electrode member 63 side. Extend (symbol r K2 in the figure)). The electrode member 63 is extended toward the guide member 65, and has a region L2a extending from the bottom 63a of the electrode member 63 in a continuous state and extending from the bottom 63a of the electrode member 63. (The so-called island structure (isolated structure)) area L2b. Further, in the case where the electrode member 63 is extended toward the guide member 65, in other words, the contact between the electrode member 63 and the guide member 65 is adhered to the adhesive portion before the adhesion (welding). The surface is located in the range (region) of the member for the rod 65, and the region including the component of the electrode member 63 is present in the inner side of the outer periphery of the electrode member 63 before welding. 2〇 The region including the components of the electrode member 63 may be continuously distributed from the outer periphery of the electrode member 63 before welding, or may be independently distributed. Further, the abutting surface of the electrode member 63 and the welding member 69 before welding (corresponding to one of the line segments C2 to C2) is changed by welding, and includes a region constituting all the components of the electrode member 63, and the abutting surface is exceeded. The line segment 匸2~ 23 200921743 C2 and protrudes 'this boundary line u is not a straight line, and, in other words, forms an irregular shape with the same period, and the shape is extended to be irregular and electrode When the member 63 and the welding member 69 are extended toward each other 5, the bonding is performed on the bonding portion, and the electrode member 63 and the bonding member 69 are bonded before the bonding (welding). The contact surface to be abutted is located further on the electrode member 63 (the region on the side of the flip member (9)), and the region including the component of the snap member 69 is present. On the contrary, the contact member 69 is located on the contact member 69.

An alloy region Q2 between the electrode member 63 and the refining member 69 is formed in the alloy region R2 of the valley member 69 and the rod member 65 and at the boundary (10) between the second member and the electric member 63. In contrast to the member for the guide rod before welding and the member for welding, the joint is linear (corresponding to the line segment D2 - D2), the alloy portion of the member for welding 69 & member 65 is guided and guided. The intersection of the rod member η, η, is also set as shown in the figure to cross the line member D2 - D2 of the abutment surface of the guide member 65 24 200921743 and the welding member 69 (crossing The irregular shape of the look).

As shown in Fig. 9, the adhesive portion is disposed on the side of the alloy region R2 facing the electrode member 63, and extends from the front end of the alloy region R2 toward the extending end of the guide member 65. . Second, specify the amount of protrusion. The protrusion amount 25 200921743 F2 of the electrode member 63 after the fusion is 0.17 [mm], and the amount of protrusion E2 of the alloy region R2 toward the electrode member 63 side is E. 〖7{mmJ degree. The amount of protrusion G2 of the electrode member 63 of the guide bar member 65 is about 2424 [mm], and the amount of protrusion H2 of the alloy region R1 toward the side of the bar member 65 is 〇24. ]degree. 7_About the welding strength test The electrode preparation of the present invention (hereinafter referred to as the invention) was subjected to a tensile test. In the tensile test, the electrode member and the guide member for the electrode preparation body are fixed, and the tensile load of the adhesive portion of the electrode assembly is parallel to the axial direction of the member for the guide bar. The tensile load was calculated from the damaged load. Further, in comparison with the product of the present invention, the same tensile test was carried out on the electrode preparation body (hereinafter referred to as a conventional product) manufactured by the conventional method described above. (1) Invention The invention product is the electrode preparation body 61 of the above embodiment. As shown in Fig. 3, the electrode member 63 before welding has a full length L1 of the tube portion in the direction of the center of the core of 5. 〇 [mm], and an outer diameter D1JU 7 [called, the thick portion of the tube portion is the bottom portion 6 mosquitoes are thicker Peach 2 [mm]. The outer diameter D2 of the member 550 for the ray-sliding bar is 〇.8 [_, the member for the fusion bonding 69 before the splicing is set to be a circular plate (which is used by the stencil), and the total thickness is 〇2 [mm], the outer diameter. for. 8-]. To load this electric _ long 61 glass f 31 light for 3_ silly for 2 [mm]. As shown in Fig. 4 (4), the irradiation of the laser is at the interval of 3 26 200921743 in the circumferential direction of the member for the bonding (between the member for the core member 63 and the member for the guide bar 65). As shown in (b), the angle B between the irradiation direction of the laser beam and the axis of the rod member 65 is in the range of 5 degrees or more and 30 degrees or less, for example, 15 degrees. Once the angle of the laser is set to be less than 5 degrees, the laser light is blocked by the electrode member 63, and thus it is not preferable. On the other hand, when the angle of the laser is set to be larger than 30 degrees, the member for the guide bar 65 and the member for welding 69 cannot be effectively irradiated, which is not preferable. The conditions at the time of laser processing when the electrode preparation body 61 is manufactured are as described above, the power intensity of the laser is 4.6 [kW], and the irradiation time is 15 [ms]. Further, the conditions and the irradiation position of the laser processing are taken as an example. Of course, when the material and size of the member 61 for the electrode 10 are changed, the conditions are also changed. Further, it can be seen that in the pattern 1 and the pattern 2, the materials and dimensions of the electrode member 61, the welding member 69, and the guide member 65 are the same, and the conditions of the laser processing are the same as the irradiation position, but the extension structures are mutually different. (2) Conventional product 15 Fig. 10 is a view showing a conventional product used for a tensile strength test. The electrode preparation body (referred to as a conventional product) 9 21 manufactured by a conventional method is composed of the electrode member 923 and the rod member 925 in the same manner as the invention. Here, the electrode member 9 2 3 has a cylindrical portion 923a having a circular cross-sectional shape, a bottom portion 923b that plugs one end of the cylindrical portion 923a, and an outer side extending from the bottom portion 20 923b to the opposite side. The outer fitting portion 923c of one end portion 925a of the rod member 925 has a longitudinal cross-sectional shape of an "H" shape. The irradiation of the laser when the electrode preparation body 921 is manufactured by a conventional method is as shown by the arrow in Fig. 10, and is placed at a plurality of positions at equal intervals in the circumferential direction of the bar member 925 (for example, at 12 degrees). At three equal intervals, the laser light 27 200921743 is directed toward the guide bar 9 925a that has been inserted into the (four) portion 923 (10). The electrode member 92i having the shape of the above-mentioned "H" and the member for the electrode having no external P (for example, the electrode member 5 901 described in the background art) tend to have a high adhesive strength. The invention requires a higher adhesive strength than conventional products of this shape. Explain the specifications of the known products. The electrode preparation body 921 is composed of an electrode member 923 made of nickel (Ni) and a member 925 made of tungsten (w). As shown in the first figure, the electrode member 923 before the welding is 9L1 in the axial direction of 5.5 [mm], the outer diameter 9D1 is 1.7 [_], and the thick portion 9tl of the tubular portion is 〇.l [ Mm]. The thick portion %2 including the bottom portion 923}3 of the outer fitting portion 923c is 〇_75 [mm]. The outer diameter 9D2 of the guide member 925 before welding is 0.8 [mm]. The conditions at the time of laser processing when the electrode preparation body 921 is manufactured are as described above, and the power intensity of the laser is in the range of 5 [kW] or more and 8 [kW] or less, and the irradiation time is 4 [ms] or more and 5 [mm]. The following range. (3) Test results Five tests were carried out on the inventive product and the conventional product, and the average value thereof was 199 [N] in the invention product 61, whereas the conventional product 921 was 132 [N], and the invention product 20 61 and the conventional product. The 921 comparison 'can be found to be about 1.5 times. In other words, the electrode preparation body 61 of the present invention can be said that the adhesion strength between the electrode member 63 and the rod member 65 is increased by about 1.5 times with respect to the electrode preparation body 921 which is produced by a conventional method. This is because the electrode member 63 and the adhesive portion 28 of the guide member 65 are irregularly extended from each other, and the area of the alloy region in the region where the structure is extended is enlarged, thereby improving the adhesion strength. The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and for example, the following aspects can be also employed. 5 1. Electrode preparation body (1) In the case of the presence or absence of the welding member, the electrode member and the rod member are indirectly bonded to each other through the welding member, but the electrode member may be used. It is directly adhered to the member for the guide bar. In this case, it can also be seen that the adhesive member of the electrode member 10 and the member for the guide bar can be provided with the structure of the south electrode as described in the embodiment. Adhesion strength to members for guide bars. (2) Shape The shape of the electrode member is a bottomed cylindrical shape, that is, a cup shape, but may be other shapes. The other shapes are the "H" shape described in the above 15 "About the welding strength". (3) Material In the embodiment, the material for the electrode member is nickel, and the material for the rod member is an alloy of nickel and iron. However, other materials may of course be used. For example, molybdenum can be used as the member for the electrode and the member for the guide bar, and cobalt can also be used for 20 . However, in the present invention, at least one of the member for the electrode and the member for the guide bar is adhered to the structure that protrudes irregularly toward the counterpart member side. Therefore, it is necessary for both members to have a melting point that is extended by heating such as laser. Specifically, the difference in melting point between the two members is in the range of 500 [°C] or less, and in order to have a better 29 200921743 extension, the difference in the melting point is preferably in the range of 100 [°C] or less. Fig. 11 is a schematic view showing the distribution of elements when a member for a guide bar is formed by a key. The electrode preparation body 101 of the present example is an electrode member 5103 made of nickel, a bar member 105 made of indium, and is disposed between the electrode member 103 and the bar member 105, and is used for combining the two. The welding member 107 is configured. Further, the welding member 107 is made of cobalt. The electrode preparation member 101 is an adhesive portion of the electrode member 103 and the guide member 105 that is welded to the welding member 107, and includes a region constituting all the components of the welding 10 member 107 (the symbol "L3" in Fig. 11 It is a structure which protrudes toward the side of the guide member 105. Further, at the adhesive portion, at least one of the components constituting all the components of the welding member 107 (indicated by the symbol "R3" in Fig. 11) and the components constituting the electrode member 103, and the member constituting the welding member 107 are included. A region (indicated by the symbol "K3" in Fig. 11) of at least one of the components is divided into a structure that is irregularly extended toward the electrode member 103 side. The line segment 13 indicating the boundary between the electrode member 103 and the alloy region K3 is formed in an irregular shape as shown in Fig. 11, and the electrode member 103 and the welding member 107 are mutually extended to each other from the electrode member 103. The extension area 20 (the symbol "L3" in the figure) and the extension area (symbol "R3" in the figure) from the welding member 107, the amount of protrusion, the extension width, the shape and the extension The number of regions is different, and an irregular protruding structure is formed. As a result, the adhesive portion has an irregular protruding structure, thereby increasing the adhesion strength of the adhesive portion. 30 200921743 (4) In the case of the welding implementation, the case where the laser is used as the (four) method is described, however, as long as the electrode member and the member for the guide bar are adhered (including the case of the member for welding) It is configured such that at least one of the inside thereof protrudes toward the other member side, and the structure is maintained to directly or indirectly adhere (solder) the electrode member and the guide member. For example, it is also possible to use a combination of laser welding and resistance welding.

The rod is fused by a member. After the electrode member and the member for the guide bar are electrically fused to each other, the sealing member is bonded to the member for the guide bar, and the splicing is performed. The bundle ' is subjected to a reduction treatment to remove the above oxide film. 15 20 In this case, the children of the guide bar and the member for the induction wire are subjected to resistance welding, and then the oxygen is cut into the original order, and the fairy is formed by the shape f' which forms the oxide film first. After the connection is made, the welding current is unstable, and the welding strength is unstable. In addition, after the electrode member and the member for the guide bar are electrically connected to each other, the reason for the refining of the sealing body is caused by The true seal H% will cause the seal to be skewed or cracked due to (4) and (4). In the case where the electrode member is required to be melt-bonded by the state in which the oxide film is formed, the stable fusion strength can be obtained irrespective of the presence or absence of the oxide film. 31 200921743 In the case of using the crucible for the electrode member, in the reduction treatment, hydrogen is absorbed and becomes brittle. Therefore, after the rod member for forming the oxide film is welded and sealed, It is necessary to weld the member for the guide bar and the member for the electrode, and the laser welding is suitable for use. 5 2. Lamp shape In the above embodiment, the glass tube of the lamp is provided in a straight tubular shape, however, it is of course impossible to have other shapes. Other shapes include, for example, a "two" shape, a "U" subshape, an "L" shape, a "v" shape, and a ring shape. Further, in the above embodiment, the glass tube has a straight tubular shape and has a curved portion, and 10 may have a curved portion at one or two or more places. 3. Glass tube for lamp The glass tube for the implementation of the sample is not limited to lead-free glass or borosilicate glass, and may also be used with mis-glass, sodium or glass. In this case, in order to improve the dark startability, the sodium content in the glass is preferably 5 [m〇l%] or more and I5 20 [mol%] or less. That is, the above-mentioned glass contains a large amount of an alkali metal oxide typified by sodium oxide. For example, when it is sodium oxide, the sodium (Na) component is eluted to the inner surface of the glass tube over time. This is because sodium has a low electrical negative degree, so that sodium eluted to the inner end portion of the glass tube (without forming a protective film) enhances the improvement of the dark startability. Further, by adjusting the expansion coefficient of the glass constituting the glass tube, it is possible to increase the packing strength of the guide wire and the glass in the portion of the discharge lamp in which the guide wire is filled. For example, in the case where the guide wire is made of tungsten, the expansion coefficient of the glass is preferably set to be 36×10 7 [K—!] or more and 45χ1 (Γ7[Κ—丨] or less. In this case, the metal in the glass is examined. The total amount of the component and the alkaline earth metal component is set to 32 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 21 In the case of Invar made of Kovar and indium, the coefficient of expansion of the ruthenium is preferably set to be less than or equal to 56x10 5 [K ] of ASxlOlK-1]. In this case, the metal component in the glass is used. In the state in which the total of the metal components of the soil tester is set to 7 [mol%] or more and 14 [mol%] or less, the expansion coefficient of the rupture can be set in the above range. Moreover, the guide line is made of Dumet or In the case of alloys of iron, nickel and chromium, the expansion coefficient of the glass is preferably set to 94 χ 1 (near Γ7 [ΚΜ]. In the case of 10, the total alkali metal component and alkaline earth metal component in the glass are combined. In the state of 20 [mol%] or more and 30 [mol%] or less, the expansion coefficient of the glass can be set in the above range. The metal oxide is doped to the glass by a predetermined amount thereof, thereby absorbing ultraviolet rays of 254 [mm] and 313 [mm]. Specifically, 15 is, for example, titanium oxide (Ti〇2), which is doped with a doping composition. The ratio of 0.05 [mol%] or more absorbs 254 [mm] of ultraviolet rays, and the doping composition ratio is 2 [mol%] or more, and r can absorb 313 [mm] of ultraviolet rays. However, the doped titanium oxide has a composition ratio of 5.0 [ In the case where there is a large amount of mol%, the glass is devitrified, so it is preferable that the doping composition ratio is 0.05 [mol%] or more and 5.0 [mol%] or less. 20 Further, in the case of cerium oxide (Ce〇2) In the case where the doping composition ratio is 0.05 [mol%] or more, ultraviolet rays of 254 [mm] can be absorbed. However, in the case where the oxidized doping composition ratio is more than 0.5 [mol%], the glass is colored, so that cerium oxide is used. The doping composition ratio is preferably in the range of 0.05 [mol%] or more and 0,5 [mol%] or less. Further, by doping tin oxide (SnO) with oxidation, it is possible to suppress the coloring of the glass caused by the oxidation of 33 200921743. Therefore, the oxidizing planer may be doped to a composition ratio of less than 5.0 [mol%]. In this case, if the cerium oxide doping composition ratio is 〇5 [m〇1%] or more, Absorbs 313 [mm] of ultraviolet light. However, in this case, when the composition ratio of yttrium oxide is more than [5 [mol%], the glass will be devitrified. 5 In the case of oxidized (ZnO), Ultraviolet rays of 254 [mm] can be absorbed at a doping composition ratio of 2.〇[m〇i %] or more. However, when the zinc oxide doping composition ratio is more than 10 [mol%], the expansion coefficient of the glass becomes large. When the guide wire is made of tungsten, the expansion coefficient of the guide wire (which differs from the expansion coefficient of the broken wire, and becomes difficult to fill, so the composition ratio of the zinc oxide doping 10 is 2.0 [m〇l%] or more. A range of 10 [m〇l%] or less is preferred. However, when the guide wire is made of cobalt or molybdenum, the expansion coefficient of the guide wire (about 51 χ 1 〇 ~ [Κ is larger than that in the case of tungsten, so the zinc oxide doping composition ratio is less than 14 [mol%]. Moreover, in the case where the zinc oxide can be doped to a composition ratio of more than 2 〇 [1%], the glass may have devitrification, so the zinc oxide doping composition ratio is 15 [m〇l%] or more. In the case of iron oxide (Fe 2 〇 3), 254 [mm] of ultraviolet rays can be absorbed at a doping composition ratio of 〇·〇1 [mol%] or more. However, in the case where the iron oxide doping composition ratio is more than 2.0 [m〇l%], the glass is colored, and therefore the iron oxide doping composition ratio is 2 〇 [m 〇 1%] or less 2 〇 [m 〇 1%] or less 2 Further, the infrared transmittance coefficient indicating the moisture content in the glass is preferably in the range of 〇3 or more and 1.2 or less, and particularly preferably adjusted to a range of 〇4 or more and 〇8 or less. The infrared transmittance coefficient is 丨. 2 or less, it is easy to obtain high-power electricity that can be applied to external electric (four) money (EEEL) and long strip cold cathode (four) lamps 34 200921743 Low loss of pressure applied lamps When the value is less than 0.8, the loss factor is very small, and it can be applied to a high voltage application lamp. Further, the infrared transmittance coefficient (X) can be expressed by the following equation: [Equation 1] X = (log(a/b)) /t 5 a : transmittance at a very small point near 3840 [〇11-1] [%] b : transmittance at a very small point near 3560 (^111-1] [%] t : glass thickness 4. discharge lamp In the above-described embodiment of the phosphor layer, YOX, LAP, and RAM are used as the working body 10 particles. However, the phosphor particles of the present invention are not limited to the above-described ones, and other phosphor particles may be used. Including the above materials, the blue phosphor particles are in the range of 430 [nm] or more and 460 [nm] or less, and the green phosphor particles are in the range of 510 [nm] or more and 550 [nm] or less. The light-emitting particles are in the range of 600 [nm] or more and 780 [nm] or less, and each of them has a light-emitting peak. (1) Ultraviolet rays. For example, in recent years, the liquid crystal color television has been enlarged to block the backlight mode. The open diffuser of the group is made of polycarbonate with good dimensional stability. This polycarbonate will emit 313 due to mercury absorption. The ultraviolet light of 20 nm is easily degraded. In this case, it is preferable to use a phosphor particle which can absorb ultraviolet rays having a wavelength of 313 [nmj.

For example, only BAM-B is used in blue (absorption 313 [ Nm]), use LAP (no absorption 313 [nm]) and BAM-G (absorption 313 [nm]) in green, Y〇X (non-absorption 313 [nm]) and YVO (absorption 313 [nm] in red Phosphor particles, in this case, the phosphor particles 15 having a wavelength of 313 [nm] are adjusted to When the weight composition ratio is more than 50 [%], ultraviolet rays are prevented from leaking out of the glass tube. Therefore, when the phosphor layer contains phosphor particles capable of absorbing ultraviolet rays of 313 [nm], it is possible to suppress the backlight from being blocked. The diffusion plate made of polycarbonate in the opening of the module is deteriorated by ultraviolet rays, and the characteristics of the backlight module can be maintained for a long period of time. Here, the so-called "absorbing 313 [nm] ultraviolet rays is 254. The excitation wavelength spectrum in the vicinity of [nm] (the so-called excitation wavelength spectrum is such that the wavelength of the phosphor particles changes while the excitation light is emitted and the excitation wavelength and the emission intensity are plotted) is set to 100 [%]. The intensity of the excitation wavelength spectrum of [nm] is determined as 80 [%]. That is, the illuminant particles that absorb ultraviolet rays of 313 [nm] are glomer particles that absorb 313 [_] ultraviolet rays and can be converted into visible light. (2) High-color reproducibility In a liquid crystal display device typified by a liquid crystal color TV, a high-color reproduction is performed as a ring of high quality in recent years, and a backlight module of the liquid crystal display device is used. The cold cathode glory lamp used for the light source is required to be magnified by the reproducible chromaticity range. 1 〇 For such a requirement, for example, the following phosphor particles can be used to achieve the use of phosphor particles in a more practical manner. The range of chromaticity is further expanded. Specifically, in the CIE1931 chromaticity diagram, the chromaticity coordinate value of the phosphor particles for high-color reproduction is located in a triangle formed by the chromaticity coordinate values of the three phosphor particles used in the implementation mode. And expand the coordinates of the color reproduction range. Ls The chromaticity coordinate value of the phosphor particles (powder) described below is the value measured by the spectroscopic analysis device (MCPD-7000) manufactured by U Otsuka Electronics Co., Ltd., 4 points below the decimal point. The number of digits is rounded off, and the value of the chromaticity seat is a representative value of each of the phosphor particles, which may be caused by a measurement method (measurement principle) or the like. (a) Blue 2〇铕 activates lithium chloroapatite [Srlfl(P0〇6Cl2:Eu2+) (abbreviation: SCA), chromaticity coordinates: x=〇. 153, y=0. 030 You can use strontium to activate strontium calcium strontium apatite [(Sr, Ca, BaMP 〇 4) 6Cl2: Eu 2+] (abbreviation: SBCA), and the above-mentioned SMM-β which can also absorb ultraviolet rays having a wavelength of 3l3 [nm] can also be used. For high color reproduction 38 200921743 (b) Green BAM—G, chromaticity coordinates: x=0_ 136, y = 0· 572 CMZ, chromaticity coordinates: x=0. 164, y=0. 722 CAT, color Degree coordinates: x = 0. 284, y = 0. 635 5 铽 manganese co-activated strontium aluminate [CeMgAln〇19: Tb3 + Mn2 + ] (abbreviation - CAM), chromaticity coordinates: x = 0. 256 , y=0. 657 Manganese activated zinc citrate [Zn2SI〇4: Mn2+] (abbreviation: ZSM), chromaticity coordinates: x == 0. 248, y = 0. 700 Again, these substances are as described above It can absorb the ultraviolet 10 line of wavelength 313 [nm]. In addition to the three types of phosphor particles described here, MGM can also be used for high color reproducibility. (c) Red YOS, chromaticity coordinates: x= 0.658, y=0. 330 YVO, chromaticity coordinates: x=0. 661, y=0. 328 15 MFG, chromaticity coordinates: x = 0. 708, y = 0. 288 Again, this As described above, it is possible to absorb ultraviolet rays having a wavelength of 313 [nm], and YVO and YDS can be used for high color reproducibility in addition to the three types of phosphor particles described herein. The coordinate value is only a representative value of the respective phosphor particles 20, and there may be some values of the chromaticity coordinates indicated by the respective phosphor particles and the above values due to the measurement method (measurement principle) and the like. In the case of the difference, the chromaticity coordinates of each of the phosphor particles of the above embodiment are YOX (x=0· 643,y = 0. 348), LAP (x=0.351, y=0. 585), 39 200921743 y=〇.〇55) Composition. BAM-B (x= 〇. i4g and 'the phosphor particles used to emit the red, green, and blue lights are not limited to the respective wavelengths, and can be used in combination. The above-described high-color reproduction phosphor particles form an h-shape of the work layer, and the evaluation here is in the αΕ1931 chromaticity diagram.
