Field of the Invention The present invention relates to a discharge lamp having a susceptor and an ultraviolet ray irradiation apparatus using the same, particularly for manufacturing a liquid crystal substrate such as a television or a display. A discharge lamp having a susceptor and an ultraviolet ray irradiation device used for manufacturing a liquid crystal using a liquid crystal material containing a photosensitive material, in particular. [Prior Art] In the liquid crystal display device, the direction of the axis of the refractive index is changed by applying a voltage to the liquid crystal to change the direction of the refractive index anisotropy of the liquid crystal panel, thereby controlling the intensity of the transmitted light of the liquid crystal panel. In such a liquid crystal display device, it is very important to control the arrangement of liquid crystal molecules in a state where no voltage is applied to the liquid crystal. In the method of manufacturing a liquid crystal panel, in order to obtain a high-luminance and high-speed-reactive MVA panel, a liquid crystal composition containing a polymerizable component is held between the substrates, and the polymerizable component is polymerized in a state where a voltage is applied. Techniques for the tilt direction of liquid crystal molecules are known. This technique is called PSVA (Polymer Stabilized Vertically Aligned nematic), for example, as described in the patent literature! Wait . In this technique, as the polymerizable component, a monomer material which is polymerized by ultraviolet rays can be used. There is a problem associated with display non-uniformity in a liquid crystal substrate using a monomer material. This should be caused by incomplete polymerization and deformation of the polymer. -5- 201123256 In order to prevent such poor polymerization, it is necessary to properly irradiate the monomer material with light temperature and strict temperature management. Although the light used for the polymerization varies depending on the type of the monomer material, the ultraviolet ray is a wavelength band of 3 1 Onm to 380 nm. In order to complete the polymerization, it is generally necessary to carry out long-time light irradiation, and therefore it is preferable to use a light source lamp which is excellent in efficiency. In view of the above, the inventors of the present invention have developed the lamp for a light source shown in Fig. 1 . In the discharge lamp 1, the pair of electrodes 3 and 4 are opposed to each other via the discharge space S on the upper and lower surfaces of the flat rectangular light-emitting tube 2 made of a dielectric material. A rare gas (e.g., gas) is sealed in the discharge space S, and when a high-frequency voltage is applied between the electrodes 3 and 4, a dielectric barrier discharge is generated in the discharge space. Further, on the inner surface of the arc tube 2, an endowment live bismuth borate (S r - B - 0 : E u (hereinafter referred to as SBE )) phosphor, an endowment-active magnesium aluminate strontium (La-Mg-Al-0) : Ce (hereinafter referred to as LAM) phosphor (5), such as a phosphor, a phosphoric acid (La-PO: Gd, Pr (hereinafter referred to as LAP: Pr, Gd) phosphor, etc. According to the discharge lamp, It can emit light with a maximum energy peak at 3 1 0~3 8 Onm in the ultraviolet spectrum, and can be utilized as a high-efficiency light source with a discharge lamp. However, in the discharge lamp, the wall temperature of the arc tube 2 is known. Therefore, as shown in Fig. 12, in the case where the discharge lamps 1, 1 and the substrate (panel) W are directly opposed to each other to illuminate the light, the heat of the discharge lamp causes the temperature of the cell to be
-6 - 201123256 升，而發生無法進行聚合處理的問題。 因此，在用來保持單體材料之面板基板，也必須維持 最佳的溫度狀態。 萬一面板基板之溫度管理不夠完善，而無法適當地進 行單體材料的溫度管理的話，會發生聚合不良，而在最終 製品之液晶面板可能發生殘影（burning)的問題。 有鑑於此，爲了確實地進行放電燈的溫度控制，例如 可考慮像專利文獻2那樣，使用冷卻套管等而將放電燈予 以個別冷卻的方法。 然而，近來，作爲工件之液晶面板大小超過2000mm 之大型面板並不少見，用來處理面板之放電燈的長度當然 需要更長的長度。因此，即使是採用上述具有冷卻構造的 裝置，長型的放電燈之處理會變得極爲煩雜，特別是讓放 電燈相對於冷卻套管進行出入的作業變得極爲困難。 [專利文獻1]曰本特開2008-123008號公報 [專利文獻2 ]日本特開2 0 0 8 - 2 3 5 6 7 8號公報 【發明內容】 本發明是有鑑於上述習知技術的問題點，是針對在介 電質構成的發光管的外面將一對電極相對置且在該發光管 的一·端部設置前述電極的供電機構之具有基座之放電燈， 爲了提供：相對於紫外線照射裝置之冷卻管使該放電燈的 插入變容易’且能簡單地相對於紫外線照射裝置之框體進 行拆裝的具有基座之放電燈。 201123256 再者，是針對具備框體及裝設於該框體的放電 外線照射裝置，爲了提供：相對於設置於該框體之 內使上述具有基座之放電燈能容易且順利地插入， 將該放電燈裝設成可相對於框體進行拆裝的狀態之 照射裝置。 爲了解決上述課題，本發明之具有基座之放電 外線照射裝置，其特徵在於，在前述發光管之與供 側端部相反側的非供電側端部裝設基座，在該基座 發光管進行滑動、導引之導引機構。 此外具有：在前述發光管的基座設置複數個滑 特徵，又進一步具有：該基座是相對於發光管形成 自如的特徵。 另外，其特徵在於，在紫外線照射裝置之框體 卻管，上述具有基座之放電燈，是在該冷卻管內藉 導引機構以滑動狀態導引而進行插入，並藉由前述 拆裝地卡合於前述框體之卡合構件。 再者，其特徵在於，前述具有基座之放電燈， 供電機構而被框體的支承機構可拆裝地支承著。 依據本發明，藉由在具有基座之放電燈的非供 部安裝基座，且在該基座設置導引機構，當要在設 外線照射裝置之冷卻管內插入放電燈時，例如即使 的放電燈，利用該導引機構可順利且容易地插入放 而發揮能使放電燈更換作業非常順利地進行之效果 此外’藉由使導引機構具備複數個滑動體，在 燈之紫 冷卻管 又容易 紫外線 燈及紫 電機構 設置沿 動體的 可拆裝 設置冷 由前述 基座可 是藉由 電側端 置於紫 是長型 電燈， 〇 冷卻管 -8 - 201123256 內插入放電燈時，能保持穩定的放電燈姿勢，而使插入作 業變得更容易。 再者’藉由使基座相對於發光管形成可拆裝自如，在 更換放電燈時，僅須將基座卸下後更換發光管即可，因此 經濟性佳。 此外’具有基座之放電燈，隨著往紫外線照射裝置之 框體的冷卻管內插入，在其非供電側端部會自動可拆裝地 卡合於框體，因此可謀求作業時間之縮短化。 【實施方式】 紫外線照射裝置1 〇，是在框體11具有一對的外壁 1 2a、1 2b ’在大多的情況，依據作業環境僅在其中—方的 外壁12a形成開閉部13。 在框體1 1的內部，設有光透過性構件，例如是石英 玻璃構成的冷卻管1 4。該冷卻管1 4，圖中雖僅顯示一根 ，但一般是具備複數根。 該冷卻管1 4 ’是藉由垂設於框體1 1的頂部1 5之內 壁16a、16b所支承。而且，在該內壁16a、16b和前述外 壁1 2之間形成冷卻空氣流路1 7 a、1 7 b。 具有基座之放電燈20，是插入冷卻管14內而被支承 ，藉由流過冷卻空氣流路1 7 a 冷卻管1 4 4冷卻空氣流路 17b之空氣而被冷卻。 第2圖係顯示本發明之具有基座之放電燈20，其基 本的放電燈構造是與第11圖相同。亦即，在扁平方形的 -9 - 201123256 發光管21的上下表面設有一對的外部電極22、23。 在前述發光管21的一端設置供電機構24，藉由供電 線2 5、2 6對前述電極2 2、2 3施加高頻電壓。藉此’在發 光管2 1內部的放電空間產生介電質阻障放電。 例如放電氣體爲氙氣的情況，藉由放出波長1 7 2 nm 的紫外線，將塗布於發光管內部的螢光體激勵，例如放射 出3 1 0〜3 8 0nm的紫外線。 另一方面，在與設有前述供電機構24之端部相反側 的非供電側端部，設有基座3 0。參照第3圖及第4圖， 在該基座30，作爲導引機構31是在下面及兩側面設置滑 動體32、33、33。在本實施例，僅在下面的下方滑動體 3 2設置滾子3 2 a，但在左右的側方滑動體3 3、3 3也設置 滾子亦可。而且，該等滑動體3 2、3 3、3 3分別抵接於冷 卻管1 4的內周面。 再度參照第1圖，插入冷卻管1 4內的具有基座之放 電燈20，在其前端（圖中的左端），是可拆裝自如地卡 合於設置在框體1 1之外壁1 2b上的卡合構件40。 如第5圖所示，該卡合構件4 0是由垂直板41和水平 板42所構成，垂直板41固定在框體1 1之外壁12b。而 且，水平板42是在前端邊的中央形成缺口 43。 放電燈20，若從第1圖的右方的開閉部1 3插入冷卻 管14內，如第3圖及第4圖所示，放電燈20之基座30 上所設置的導引機構31之滑動體32、33、33，會沿著冷 卻管1 4的內周面滑動而進行導引，以在保持其姿勢的狀 -10- (δ) 201123256 態下卡合於左方的卡合構件40。 這時，基座3 0的下面會跑到卡合構件40的水平板 42上而被支承。這時，基座30之下方的滑動體32’是收 容在水平板42的缺口 43內，因此不會與該水平板42發 生干涉。 此外，上述卡合構件40和基座30之導引機構31 ’ 在該基座30之下方的滑動體32脫離冷卻管14之前’是 保持著基座3 0跑到前述卡合構件40的水平板42上而被 支承的位置關係。 再度參照第1圖，在冷卻管14之右端的外部，於框 體1 1之外壁12a和內壁16a之間設有支承機構50。 該支承機構5 0，如第6圖所示，是用來支承放電燈 20的供電機構24。 如第7圖所示，支承機構5 0係具備··門型構件5 1、 以及一端可轉動地連結於門型構件5 1之水平構件52。在 門型構件51設有：將放電燈20的供電機構24從上方按 壓之垂直彈簧53 ;另一方面，在水平構件52設有：將供 電機構24從後方按壓之水平彈簧54。 此外，在門型構件5 1的側面設有卡合銷5 5 ,而且在 水平構件52設有與該卡合銷55卡合之卡合片56。 要將放電燈2 0插入冷卻管14時，如第7 b圖所示， 水平構件52是呈開放的，在此狀態下將放電燈2〇插入。 放電燈20的前端，若如第1圖所示卡合於卡合構件4〇而 定位於既定位置時，如第7b圖所示水平構件5 2會轉動而 -11 - 201123256 讓卡合片56卡合於卡合銷55。 在此狀態下，水平構件5 2是從放電燈2 〇之供電機構 2 4的下方進行支承，且藉此水平彈簧5 4將放電燈2 〇從 後方按壓。 另一方面’門型構件5]之垂直彈簧53是將供電機構 24從上方朝水平構件5 2的方向按壓，而藉此進行支承。 如此般，放電燈2 0之前方的非供電側端部的基座3 〇 以及供電側端部之供電機構24，是分別藉由卡合構件40 及支承機構50予以支承而定位於既定的位置。 此外’以上所示的情況，卡合構件4 0的水平板4 2是 將基座3 0本身從下方支承’第8圖則顯示基座3 0和卡合 構件40之水平板42的不同位置關係之其他實施例。 圖中是設定成：水平板42將基座30的側方滑動體 3 3、3 3從下方支承的位置關係。 這時當然也是’在下方滑動體32從冷卻管14脫離之 前，水平板4 2形成與側面滑動體3 3、3 3卡合的位置關係 〇 第9圖係顯示滑動體的其他實施例，兩個滑動體3 5 、3 6，爲了將放電燈從下方支承，如圖示般設置成以大致 八字形往下方展開的狀態。在此情況也是，在該滑動體 35、36設置滾子亦可。 再者，第1 〇圖係顯示基座3 0的其他實施例。該基座 3 0是可拆裝地安裝於放電燈2 0的發光管2 1。在發光管 2 1安裝保護構件3 7，基座3 0安裝在該保護構件3 7上， -12- 201123256 並藉由安裝螺釘38等予以固定。 如以上所說明，依據本發明之具有基座之放電燈，藉 由在發光管之非供電側的端部安裝基座，並在該基座設置 導引機構’要將放電燈組裝於紫外線照射裝置之冷卻管內 時’藉由該導引機構能夠順利且容易地插入，可大幅縮短 長型的放電燈之更換作業時間且能確實地作業，而具有優 異的效果。 【圖式簡單說明】 第1圖係本發明的紫外線照射裝置之局部截面圖。 第2圖係本發明之具有基座之放電燈的整體立體圖。 第3圖係第1圖的局部立體截面圖。 第4圖係第3圖的橫截面圖。 第5圖係第1圖的主要部分立體圖。 第6圖係第1圖之其他的主要部分立體圖。 第7(A) (B)圖第6圖的支承構件單獨之作用說明 圖。 第8 ( A ) ( B )圖係卡合構件的其他實施例。 第9圖係滑動體的其他實施例》 第10圖係基座的其他實施例。 第1 1 ( A ) ( B)圖係習知的放電燈。 第1 2 ( A ) ( B )圖係習知的紫外線照射之槪念圖。 【主要元件符號說明】 -13- 201123256 10 ： 11: 14: 20 ： 2 1: 22、 24 ： 30 ： 3 1: 32 ： 33、 4 0 ： 4 1: 42 ： 43 ： 50 ： 5 1: 紫外線照射裝置 框體 冷卻管 具有基座之放電燈 發光管 23 :電極 供電機構 基座 導引機構 下方滑動體 3 3 :側方滑動體 卡合構件 垂直板 水平板 缺口 支承機構 門型構件 5 2 ·’水平構件-6 - 201123256 l, and there is a problem that aggregation is not possible. Therefore, in the panel substrate for holding the monomer material, it is also necessary to maintain an optimum temperature state. In the event that the temperature management of the panel substrate is insufficient, and the temperature management of the monomer material cannot be properly performed, polymerization failure may occur, and a problem of burn-in may occur in the liquid crystal panel of the final product. In view of the above, in order to reliably control the temperature of the discharge lamp, for example, a method of cooling the discharge lamp by using a cooling jacket or the like as in Patent Document 2 can be considered. However, recently, it is not uncommon for a large-sized panel having a liquid crystal panel size of more than 2000 mm as a workpiece, and the length of the discharge lamp for processing the panel certainly requires a longer length. Therefore, even with the above-described apparatus having a cooling structure, the treatment of a long discharge lamp becomes extremely complicated, and in particular, it is extremely difficult to perform an operation of allowing the discharge lamp to enter and exit with respect to the cooling jacket.
