請參照第1圖，燈管100包括有玻璃管1〇2、導絲1〇4 及電極106。而燈管100可為日光燈管、冷陰極燈管（c〇ld Cathode Fluorescent Lamp ; CCFL)或熱陰極燈管（H〇t Cathode Fluorescent Lamp ; HCFL)，以下即以冷陰極燈管 為例加以說明。 在燈管100的應用中，通常需先將燈管1〇〇之導絲1〇4 以焊接方式與導線108作連接，接著將導線1〇8接合至連 接器110上，隨後再將連接器11〇與其他固定燈管1〇〇之 部品作連接，鮮少將燈管i⑽之導絲1()4直接焊接在固定 燈管100的部品上。 而為了省略焊接製程以節省成本，同時為了方便後續 產品中之燈管發生問題時的維㈣修，故㈣廠商設計開 發如第2圖所示之金屬套筒112。金屬套筒112係套設在玻 璃管H)2二端，並與燈管⑽a之導絲1〇4電性連接，利用 金屬套筒112將燈管跡固定於特定之使用燈管购的 部品上，例如背光模組。 此汉吕r雖^可省略焊接製程以節省成本，同時更 化組裝的便利性’產品組裝的效率，是由於金屬套筒 係直接接觸地設置在燈管100a的二端，故燈管脈 201015164 端的散熱效率遠較燈管1〇〇a之其他部分為佳。當產品（例 如使用冷陰極燈管為光源之背光模組）停止使用時，燈管 100a中的水銀會由氣態汞冷卻轉變成為液態汞，而當汞由 蒸氣轉變成為液態時，具有朝低溫處聚集之特性，同時由 上述可知，具有金屬套筒112之燈管10〇3在停止使用後， 玻璃管102令之汞容易聚集在玻璃管1〇2的二端，此一聚 集現象會使得燈管100a產生偏暗之現象，進而導致燈管 100a的使用壽命減少，另外，此一聚集現象亦會導致燈管 100a的啟動時間變長及點燈延遲等負面影響。 【發明内容】 因此本發明之目的係在提供一種燈管，利用管體與 金屬套筒之間設置隔熱層、減震層或隔熱減震層，來避免 氣態汞轉變成液態汞時聚集於管體二端，藉此除可省略燈 管導絲與導線之焊接製程，同時方便後續產品中之燈管發 生問題時的維護整修外，更可維持燈管之正常使用壽命以 及燈管啟動時間。 根據本發明之—實施例，提供一種燈管。此燈管包括： 至少具有一封閉端部的管體、至少一導電部、至少一金屬 套同以及至少一隔熱層。導電部設置在管體的端部中，且 導電邛延伸穿設至管體外。而金屬套筒係套設在管體的端 部，同時金屬套筒與導電部電性連接。至於隔熱層則設置 在金屬套筒與管體的端部之間。 根據本發明之另一實施例，提供一種燈管。此燈管包 括^體、至少一導電部、至少一金屬套筒以及至少一減 201015164 而導電部設置在管體的 外°金屬套筒套設在管 電性連接。至於減震層 間。 震層官體至少具有一封閉端部。 端部中，且導電部延伸穿設至管體 體的端部，同時金屬套筒與導電部 則設置在金屬套筒與管體的端部之 ❹ =本發明之再—實施例，提供—種燈管。此燈管包 教二恳至）一導電部、至少一金屬套筒以及至少-隔 :’。管體至少具有-封閉端部。而導電部設置於管 在==部中’Μ電部延伸穿設至管體外。金屬套筒套設 广體的端部，同時金屬套筒與導電部電性連接。至於隔 …減震層則設置在金屬套筒與管體的端部之間。 本發明之優點為，藉由追加隔熱層、減震層或隔熱減 _金屬㈣之間’除可防止汞由氣態凝結為液 態時聚集在管體之端部，進而確保燈管之使用壽命之外， 更可進-步防止金屬套筒與f體之間互相摩擦導致刮屑或 管體斷裂。 【實施方式】 請參照第3圖。在本實施例中，燈管3〇〇包括有管體 3〇2、導電部3〇4、金屬套筒306以及隔熱層308。管體3〇2 具有封閉的端部3〇2a與端部3〇2b，二導電部3〇4分別設置 在管體302之端部302a與端部3〇2b中，而每個導電部3〇4 至少包括有電極304a與導絲304b。電極3〇4a係位在管體 302的端部302a或端部3〇2b之中，而導絲3〇扑則電性連 接電極304a並延伸穿設至管體3〇2外。在其他實施例中， 導電部304之結構並不以此為限，僅需將導電部3〇4之一 201015164 • 端分別設置在管體搬之端部黯與端部·中並使 得導電部304由管體302中穿過封閉之端部⑽與端部 302b而凸伸出於管體302之外。 μ而燈管300所包括之二金屬套筒3〇6+，每個金屬套 筒306均具有側壁306a與底部遍，其中側壁规&係由 底部306b所延伸而出，此些金屬套筒3〇6以_對一方式分 別套設在管體302的端部3〇2a及端部3〇孔上，同時$，此 #金屬套筒306的底部3_亦與導電部3〇4凸伸於管體 罾 搬外之導絲遍電性連接，如第3圖所示。在其他實施 例中，當導電部304之結構與第3圖所示之結構不同時， 金屬套筒306的底部306b僅需導電部3〇4凸伸於管體3〇2 外之另一端電性連接即可。在其他實施例中，金屬套筒3〇6 之結構並不以第3圖之實施例所示的結構為限，僅需使得 金屬套筒可套設於管體302之端部3〇2a或端部3〇2b，並與 導電部304凸伸於管體302外之另一端電性連接即可/、 至於隔熱層308，其中隔熱層308係設置在金屬套筒 〇 306與管體3〇2的端部3〇2a或端部3〇2b之間，在本實施例 中，隔熱層308則設置在金屬套筒306的側壁3〇6a與管體 3〇2的端部302a或端部302b之間，如第3圖所示。隔熱層 3〇8可以塗佈或黏貼方式所形成。在本實施例中，隔熱層 3〇8係環設在管體3〇2的外側壁，但在其他實施例子中”'，'隔 熱層308可間隔地設在管體302的外側壁，而並未形成一 環狀結構，隔熱層308僅需使得管體3〇2之外側壁無法與 金屬套筒306之側壁306a直接接觸即可。此設計可以避免 -管體302之端部302a與端部302b之散熱效率高於管體3〇2 8 201015164 八他/刀，進而避免汞蒸氣冷卻形成液態汞的過程中， 集於S體302的二端部（端部302a與端部3〇2 管3〇〇的使用壽命。 在一較佳之實施例中，管體302係由包含氧化鉛（Pb〇) 的軟質玻璃材料或不含船之硬質玻璃材料所形成，其中軟 =玻璃材料之軟化溫度低於不含船之硬質玻璃材料的軟化 溫度，但軟質破壤材料的比重高於硬質玻璃材料的比重。 ^ 一實施例中’燈管·之管體3G2中包括有汞（未繪示）， g體302中之水主要功能係用來與導電部所產生之電 子互相作用以產生所需之光源，而汞通常係以液態或固態 存在於&體302中，當燈管3〇〇開始作用後，液態或固態 汞受熱變成氣態汞，故與導電部3〇4所產生之電子互相作 用成為乳氅之水蒸乳。在其他之實施例中，為了提高燈管 300的發光效益、減少導電部3G4飛賤之分子黏附於管體 〇2之内側壁產生黑化現象以及降低燈管3〇〇的啟動電 壓’燈管300之管體302中可包括有惰性氣體（未繪示）。在 -較佳實施例中，惰性氣體可為氬氣、氖氣或前述二者的 組合。 在一實施例中，為了產生可見光，故必須於管體3〇2 之内側壁覆盍螢光層（未繪示）。利用導電部3〇4接受高電壓 所產生之電子與管冑302中之汞蒸氣反應產生紫外線，激 發管體302之内側上的螢光層產生可見光。 在其他實施例中，隔熱層可以減震層或隔熱減震 層替代，以使得燈管300具有不同的特性。而減震層或隔 熱減震層之設置方式亦如同隔熱層3〇8，可利用塗佈或黏貼 9 201015164 . 方式形成。 上述已大略描述多個實施例的特徵，以使得熟悉此技 藝者能夠更了解與其對應的詳細敘述。熟悉此技藝者將可 體會到，利用本揭露作為基礎可設計或修改其他程序及結 構，以達到本說明書所介紹之實施例的相同目的及/或優 點。熟悉此技藝者亦可了解到在不脫離本揭露之精神及範 圍之等價的架構’以及在不脫離本揭露之精神及範圍内， Φ 當可作各種的更動、替代和潤飾。 【圖式簡單說明】 為了能夠對本發明之觀點有較佳之理解，請參照上述 之詳細說明並配合相應之圖式。要強調的是，根據工業之 標準常規，附圖中之各種特徵並未依比例繪示。事實上， 為清楚說明上述實施例’可任意地放大或縮小各種特徵之 尺寸。相關圖式内容說明如下。 Q 第1圖係繪示習知之燈管與導線焊接結構之側面示意 圖。 第2圖係繪示習知之燈管與金屬套筒結構之側面示意 圖。 第3圖係繪示根據本發明之一實施例之燈管結構的侧 面示意圖。 【主要元件符號說明】 100a :燈管 104 :導絲 100 :燈管 玻璃管 102 : 201015164 106 :電極 108 :導線 110 :連接器 112 :金屬套筒 300 :燈管 302 :管體 302a :端部 3 02b :端部 304 :導電部 3 04a :電極 304b :導絲 306 :金屬套筒 306a :側壁 308 :隔熱層 3 06b :底部Referring to FIG. 1 , the lamp tube 100 includes a glass tube 1〇2, a guide wire 1〇4, and an electrode 106. The lamp tube 100 can be a fluorescent tube, a cold cathode tube (CCFL) or a hot cathode tube (HCFL). The following is a description of a cold cathode tube. . In the application of the lamp 100, it is usually necessary to first connect the guide wire 1〇4 of the lamp tube 1 to the wire 108 by soldering, and then join the wire 1〇8 to the connector 110, and then connect the connector. 11〇 is connected with the other parts of the fixed lamp tube, and the guide wire 1 () 4 of the lamp tube i (10) is rarely directly welded to the part of the fixed lamp tube 100. In order to omit the soldering process to save cost, and in order to facilitate the maintenance of the lamp in the subsequent product, the manufacturer (4) designs and develops the metal sleeve 112 as shown in Fig. 2. The metal sleeve 112 is sleeved on the two ends of the glass tube H) 2, and is electrically connected to the guide wire 1〇4 of the lamp tube (10)a, and the metal tube 112 is used to fix the lamp tube to the specific parts purchased by the lamp tube. On, for example, a backlight module. Although this Han Lu r can omit the welding process to save costs, and at the same time to improve the convenience of assembly 'product assembly efficiency, because the metal sleeve is directly in contact with the two ends of the lamp tube 100a, so the lamp tube pulse 201015164 The heat dissipation efficiency of the end is much better than the other parts of the lamp 1〇〇a. When the product (for example, a backlight module using a cold cathode lamp as a light source) is stopped, the mercury in the lamp 100a is converted from liquid mercury to liquid mercury, and when mercury is converted from a vapor to a liquid, it has a low temperature. As a result of the above, it can be seen from the above that after the lamp tube 10〇3 having the metal sleeve 112 is stopped, the glass tube 102 causes the mercury to easily collect at the two ends of the glass tube 1〇2, and this aggregation phenomenon causes the lamp to be lighted. The tube 100a is caused to be dark, which in turn leads to a decrease in the service life of the lamp 100a. In addition, this aggregation phenomenon also causes a negative influence on the startup time of the lamp 100a and the delay of lighting. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a lamp tube in which a heat insulating layer, a shock absorbing layer or a heat insulating shock absorbing layer is disposed between a pipe body and a metal sleeve to prevent accumulation of gaseous mercury when converted into liquid mercury.
