200926257 九、發明說明： 【發明所屬之技術領域】 本發明涉及一種具有燈泡之電燈，其具有一種點燃區 ，點燃區中延伸著至少一電極，且該電燈包括一連接至該 點燃區之燈泡頸，燈泡頸中埋置著至少一與電極相連接的 電流供應裝置，電極由燈泡頸向外延伸。本發明亦涉及一 種電燈的製造方法。 【先前技術】 ® 在使燈的大小保持相同或甚至更小或使發光體中冷卻 器較小的情況下，同時發展通常功率較大的放電燈和鹵素 燈時可設定熱負載很大的構件。在此種燈中，一般的電流 供應零件是由鉬構成，其在溫度大約高於3 50°C時開始氧化 。由於具有電流承載銷和電流承載箔之系統例如埋置於燈 泡之石英玻璃中，則對體積較大的氧化鉬而言無空間可膨 脹。這樣會使燈由於桿裂縫或甚至由於燈爆裂而提早故障 〇 ® 由DE69927 574T2中已知一種電燈，其中在外部的 電流導體和與電流導體相連接的電流承載箔上形成一保護 層。此保護層只形成爲大約4微米至6微米厚的薄層且例 如由鉻所構成。由於毛細管形成在燈泡頸之內壁以及電流 承載箔、向外延伸而出的電流承載銷等這些零件之間’則 該保護層必須在電流承載銷之整個長度上延伸且亦須在電 流承載箔之露出的部份區域上延伸。 上述保護層之施加較費事。此外，此種施加過程所需 -5- 200926257 的成本亦較高，且施加用的方法會由於用來產生該保護層 的材料而對健康有危害。又，該保護層必須在熔化過程之 前施加在電流承載箔和電流承載銷上。 由於該文件中只有當熔化過程期間會在燈泡頸之內壁 和電流承載箔、電流承載銷之外側、以及施加於電流承載 箔、電流承載銷上的保護層之間發生毛細管現象，則較不 容易-且通常不能預見“是否可在熔化過程之後藉由該保 護層來產生一足夠的氧化保護作用”。由於在熔化時該保 © 護層的材料同樣會熔化，則所期望之更明確地產生一種足 夠的氧化保護作用是不能預料的。 【發明内容】 本發明的目的是設計一種電燈及其製造方法，其中該 電燈中承載電流的零件之氧化保護作用已改善且可較不費 事地達成此目的。 上述目的藉由一種具有申請專利範圍第1項特徵的電 燈以及一種具有申請專利範圍第9項特徵的方法來達成。 〇 本發明的電燈包括一種燈泡，其具有一點燃區。點燃 區中延伸著至少一電極。此外，該電燈包括至少一燈泡頸 ’其連接至該點燃區。燈泡頸中以區域方式埋置著一電流 供應裝置，其與延伸至點燃區和燈泡頸中的電極在電性上 相連接。電極另外由燈泡頸向外延伸。在該燈泡頸之遠離 該點燃區的一末端上形成一終端側的中空區。此中空區在 電流供應裝置之縱向中觀看時至少一部份以一種密封材料 來塡入，以便使電流供應裝置之延伸至燈泡頸中的部份受 -6- 200926257 到氧化保護。此外，在該密封材料上至少以區域方式形成 一種層，以使氧不能進入至電流供應裝置之延伸至燈泡頸 中的部份而達成保護功能。因此，此電燈除了該密封材料 之外亦包括另一層，其至少使氧化作用和氧的導通性 (permeability)大大地下降。藉由該電燈之此種佈置方式， 則電流供應裝置之延伸至燈泡頸中的部份之氧化保護作用 可獲得改良。相較於先前技術而言，同樣有效的氧化保護 作用可簡易很多地以成本較有利的方式來達成。此外，可 €1 ^ 避免使用對環境有害的材料，且施加該密封材料時不需複 雜之額外步驟。 較佳是使用一種在製造電燈時亦可用作其它用途的材 料來作爲該密封材料。於是，這樣亦可使成本下降。 所謂電極是指一種放電燈之陽極和陰極。同樣，亦能 以一種電極的槪念來說明一種白熾燈（特別是鹵素白熾燈） 之白織燈絲。 0 電流供應裝置特別是可藉由一適當位置上的燈泡頸之 材料之熔化及/或壓榨而埋置於燈泡頸中。特別佳的情況是 ’燈泡頸之形成在終端側之中空區只有在該埋置過程之後 才能以該密封材料來塡入。因此，不再像先前技術那樣， 在熔化過程之前已需在電流供應裝置上進行塗層，且在隨 後的熔化過程中期望該熔合用的塗層分佈在所期望的位置 上°在本明的有利的實施方式中，該壓榨過程已結束、該 中空區的幾何形式已知且不再改變時，可很確定且準確地 施加該密封材料。 200926257 在燈泡頸之內壁和電流供應裝置之外側之間 的空間由垂直於電流供應裝置之縱向來觀看時較 以該密封材料來塡滿。就像先前技術中所產生者 的中間區不會再產生。不期望的薄的位置因此亦 ，這些薄的位置會使氧穿過的危險性大大地提高 在徑向中觀看時，該中空區完全以該密封材料來 該中空區較佳是只形成在燈泡頸之壓榨區之 燃區之一側上。在燈泡頸之縱向且因此亦是電流 Ο 之縱向中觀看時，縱向中以較短的長度而延伸之 至少一部份塡料已足以確保能較不費事且成本有 化保護作用獲得改良。此外，藉由中空區之特定 則亦可較簡易且較不費事地施加該密封材料。 該中空區之長度及內部末端較佳是以該壓榨 該點燃區之末端作爲邊界。 該密封材料之厚度且特別是徑向中的範圍較 電流供應裝置之電流承載銷之徑向尺寸。特別是 ® 料的厚度至少是電流供應裝置之電流承載銷之半 。該密封材料之徑向範圍因此較電流供應裝置之 銷之半徑大很多。特別是電流供應裝置之周圍在 銷之區域中是由該密封材料所包圍著。 電流承載銷之外側和燈泡頸之限制該中空區 間的徑向距離較電流承載銷之外側和該中空區外 之內壁之間的距離大很多。因此，在燈泡和已熔 冷卻期間該中空區特別是顯示該燈泡頸中未形成 的中空區 佳是完全 一樣的大 不會產生 。特別是 塡滿。 遠離該點 供應裝置 中空區之 利地使氧 的位置， 區之遠離 佳是大於 該密封材 徑的二倍 電流承載 電流承載 之內壁之 部之燈泡

佳是在周圍中只圍繞該電流承載銷而形成。電流承載箔因 此在無該密封材料的情況下配置在燈泡頸中。電流承載箔 ® 和電流承載銷之間的連接區特別是一種焊接區且因此未與 連接用的材料相接觸。 於是’可簡單很多地且較不費事地施加該密封材料， 此乃因在先前技術中特別是由於電流承載箔和電流承載銷 之不同的造型而使塗層的施加變成很困難。在本發明的有 利的佈置中，在可感測的區域中已不需要設置該密封材料 0 Θ 保護用的層較佳是在氧進入之前形成在該密封材料之 k離該燈泡之點燃區之區域上。因此，較佳是形成另一在 外側的保護層以防止氧的進入。此一保護層的施加位置可 簡單而不費事地確定且可確保較佳的保護作用以使氧不會 進入。 防止氧的進入用的該保護層和該密封材料較佳是分別 由不同的材料來形成。 該層特別是形成在該密封材料之由中空區突出之區域 上。藉由此種佈置方式，則該層的平面範圍以及層厚度可 -10- 200926257 簡易地改變且可最佳化。 防止氧進入至電流供應裝置用的該保護層較佳是直接 形成在該密封材料上。在該層和密封材料之間未配置其它 的材料或其它的層。然而，原則上亦可不直接相鄰地施加 該層和該密封材料而是可在它們之間形成中間層。 防止氧的進入用的該保護層較佳是在成份上至少包括 聚醯胺（Pol imide)。亦可使該層在成份上至少包含陶瓷纖維 材料。例如，此處可使用UBE工業公司之材料Tyr anno Coat ο 該層較佳是由一種溫度直至5 00 °C時仍穩定的材料來 形成。 ， 燈泡較佳是具有至少二個燈泡頸，其相面對而終止於 該點燃區。 該電燈能以單側設有基座的放電燈來形成。該電燈亦 能以二側設有基座的燈來形成。 ^ 該電燈較佳是以放電燈來形成，但亦能以鹵素白熾燈 〇 來形成。 在本發明的電燈之製造方法中，至少一電極以區域方 式延伸至燈泡的點燃區中以及以區域方式安裝在一種連接 至該點燃區上的燈泡頸中且與一電流供應裝置相連接。此 電流供應裝置以區域方式埋置於該燈泡頸中且須超越此燈 泡頸，使此電流供應裝置經由燈泡頸的單側之中空區而向 外延伸。燈泡頸的中空區在電流供應裝置的縱向中觀看時 至少以區域方式來塡入一種密封材料’以使電流供應裝置 -11- 200926257 之延伸至燈泡頸中的部份受到氧化保護作用。在本發明的 電燈之製造方法中，在密封材料上至少以區域方式產生一 種層，以使氧不會進入至該電流供應裝置之延伸至燈泡頸 中的部份。藉由此種製造方法，則可較不費事且成本有利 地達成一種較佳的氧化保護作用。在製程中，藉由本方法 以及所選取的材料，則在與使用鉻時相比較下對環境的影 響可忽略。 電流供應裝置之延伸至燈泡頸中的部份以及電極之延 © 伸至燈泡頸中的部份較佳是藉由燈泡頸之材料之熔合及/ 或壓榨而埋置於燈泡頸中。該密封材料只有在將電流供應 裝置和電極以區域方式埋置於該燈泡頸中之後才施加至中 空區中。在該埋置過程之後的一步驟中才施加該密封材料 ，這樣可較適當且確定地安裝該密封材料。於是，可大大 地改良氧化保護作用。 該密封材料較佳是施加成使該中空區之在燈泡頸的內 壁和電流供應裝置之外側之間所形成的空間在垂直於電流 供應裝置之縱向中觀看時完全被該密封材料所塡滿。 整個中空區較佳是完全以該密封材料來塡滿。因此可 避免較大的空氣區的存在，且至少可大大地使氧的進入量 下降。 該中空區只形成在壓榨區之遠離該點燃區之此側上。 於是’只能存在一較小的體積以便至少以區域方式來塡入 該密封材料。因此，可容易地施加該密封材料且然後施加 一足夠的量以使氧化保護作用獲得改良。 -12- 200926257 該密封材料以特別有利的方式在保護氣體的大氣下施 加於該中空區中。 已顯示特別有利的是，藉由該密封材料，則在溫度大 約500°C時可防止氧侵入至燈泡頸中的期間超過500小時 。藉由密封材料之此種特殊的功能，此功能較佳是由該密 封材料之材料成份和維度以及數量所造成，則電燈的操作 適用性可大大地提高。 本發明的電燈之有利的構成亦可視爲本發明的製造方 ^ 法之有利的方式。 本發明以下將依據圖中的實施例來詳述。 【實施方式】 第1圖中顯示一種以放電燈來形成的電燈I。第1圖顯 示此電燈I之上部區域中的切面圖和下部區域中的視圖。 電燈I在本實施例中形成一種高功率的燈，其燈功率 例如是1 2 0 0瓦。 電燈I具有一燈泡1，其包括一腹部形的中央部’其上 〇 的相面對之側面上連接著一燈泡頸2和另一燈泡頸3。此 燈泡1以單件的方式來形成，且在中央部的內部中形成一 放電區4以作爲點燃區。放電區4中延伸著第一電極5’其 在本實施例中以棒形的形式來形成。第一電極5在電性上 和機械上是與電流供應裝置6，7相連接。電極5由鎢或含 有鎢之材料來製成。 電流供應裝置包括一電流承載箔6，其由鉬或含有鉬 的材料所形成且在氣密地熔合至燈泡頸2中時另外可形成 -13- 200926257 密封箔。此外’電流供應裝置包括一電流承載銷7，其同 樣是棒形且例如由鉬或含有鉬的材料所構成。 以適當的方式在相面對的側面上設置第二電極8，其 同樣以棒形方式來形成且延伸至放電區4中。此外，第二 電極8同樣至少以區域方式埋置於第二燈泡頸3中且在電 性上和機械上與電流供應裝置9，10相連接，電流供應裝 置9’ 10類似於燈泡頸2中之電流供應裝置6，7而形成。 電流供應裝置之電流承載銷10和電流承載箔9顯示在圖中 〇 本實施例中該燈I在二側上設有基座。然而，亦可設 置一種在單側設有基座的放電燈。同樣，電燈I亦能以鹵 素白熾燈來形成。 電流承載箔6和由燈泡頸2延伸而出的電流承載銷7 焊接在一連接位置13上。在該燈泡頸2之遠離該放電區4 之末端21上形成一中空區11。由於燈泡2在本實施例中設 計成一種管，則該中空區11的橫切面基本上爲圓形。燈泡 頸2之縱軸A基本上對應於電流供應裝置6，7之縱向且因 此亦對應於電極5和電流承載銷7之縱軸A。電流承載銷7 基本上是與中空區n之縱軸成共軸而配置著，其中該中空 區1 1之縱軸對應於燈泡頸2之縱軸A。 第1圖中顯示該燈I之一種已製成的狀態，其中末端 側仍安裝著基座。這表示：電流供應裝置6，7熔合於燈泡 頸中且燈泡頸2的材料被壓榨於一壓榨區22中。於是，電 流承載箔6氣密地配置於燈泡頸2中。該壓榨區22只有一 -14- 200926257 部份經由燈泡頸2之整個長度而延伸且終止於中空區丨丨之 下端，即，終止於中空區u之面向該連接位置13之末端 〇 中空區11中完全以一種密封材料12來塡滿。形成此 密封材料12’以便使電流供應裝置6，7之延伸至燈泡頸2 中的部份可受到氧化保護作用。 該密封材料12可具有一種耐溫大於8〇(rc之無機黏合 材料。然而’亦可設置一種金屬泡沬以作爲密封材料12。 中空區11只延伸至燈泡頸2之一位置，此位置與該連 接位置1 3相隔開。該密封材料丨2因此未與該連接位置i 3 相接觸且因此亦未與電流承載箔6相接觸。縱向距離是以 參考符號1來表示。 此外’電流承載銷7具有直徑dl，其較該中空區π 之直徑d2小很多。該密封材料ι2之厚度是由電流承載銷7 之外側至燈泡頸2之以該中空區丨丨爲邊界的內壁之距離來 決定，且此厚度大於（特別是大很多）電流承載銷7之半徑 ((dl)/2)。 由第1圖可辨認出，該密封材料12只在周圍包圍著電 流承載銷7。 該密封材料12只有在該埋置過程之後（即，在燈泡頸2 熔合且壓榨至壓榨區22中之後）才塡入至中空區u中。 中空區11之徑向範圍因此較燈泡頸2之材料和該連接 位置13之區域中該電流承載箔6、以及壓榨區22中的電流 承載銷7之間的毛細管大很多，該毛細管是在熔合過程和 -15- 200926257 隨後的冷卻過程中形成。 在燈泡頸3之區域中未顯示出切面圖而是顯示_種由 外部觀看之燈I之側面圖。燈I在燈泡頸3中的佈置類似 於在燈泡頸2中的佈置。例如，中空區1 4以對該軸A形成 一種半徑r的區域來表示。此處，在燈泡頸3之遠離該放 電區4之一末端31上形成該中空區14。中空區丨4同樣只 延伸至一壓榨區32。 中空區11在縱軸A之方向中觀看時由燈泡頸2之後端 ® 21之邊緣延伸至壓榨區22之開始處。 以類似的方式，須在燈泡頸3中設定中空區14之尺寸 〇 爲了製成該燈I，則電極5及電流供應裝置6, 7須插 入至管形的燈泡頸2中。然後，產生該壓榨區22，此時該 燈泡頸2在適當的位置處加熱且使石英玻璃材料溶合。此 外，在燈泡頸2之適當的位置上進行一壓榨過程，以便使 該電流承載箔6達成氣密性的熔合。然後，使燈泡頸2冷 卻且由於材料之不同的膨脹而可使未顯示的毛細管特別是 形成在該連接位置13上和該電流承載銷7的周圍。 只有在冷卻之後該密封材料12才施加至中空區11中 。以同樣方式在燈泡頸3之區域中進行該燈I之製造。 該密封材料1 2之施加是在一種保護氣體（例如，氬）之 大氣下進行。 以該密封材料1 2來達成的氧氣排除作用足以使電流 供應裝置6’ 7上的溫度在至少5〇〇艺時持續至少5〇〇小時 -16- 200926257 。對應的情況亦適用於燈泡頸3之區域中。 若使用一種無機黏合材料（例如，Cerastil®)作爲密封 材料1 2 ’則該黏合材料亦可用來在該燈I上施加該基座。 在該燈I佈置成鹵素白熾燈時，較佳是與基座之安裝 步驟同時或至少暫時地同時在中空區Π中施加或安裝該 密封材料1 2。 依據該燈I在燈泡頸2之區域中的佈置所示的方式可 類似地用於燈泡頸3中的佈置或進行方式中，或在該燈I ® 具有上述之第二燈泡時亦可用於該燈I之相對應的第二燈 泡頸中。 就像由第1圖，中可辨認出的一樣，中空區n和14形 成在面向放電區4之末端上。 藉由中空區11和14之環境和維度，該密封材料12亦 可形成軟木塞形式的密封。依據第1圖所不，該密封材料 12超過後部邊緣或後端21之邊緣而延伸。 就像第1圖所示，在密封材料1 2上形成另一保護用的 ❹ 層16以使氧不能進入至電流供應裝置6，7，9和10中。 此層16直接形成在該密封材料12之表面15上，其中此表

中之後施加在表面15上。此層16可由聚醯胺或陶瓷纖維 材料所構成且特別是在直至溫度5001時仍然具有溫度穩 定性。藉由此層1 6，則可使氧的透過性更小且可使可能發 生的軸跳躍的時間延後。500°C時高溫保護的期間可藉由此 層16而獲得15%至20%之改良。這樣對具有基座之全部的 放電燈和鹵素白熾燈都可確保其可用性。 Ο 【圖式簡單說明】 第1圖電燈的側視圖和部份切面圖。 【主要元件符號說明】 Ο

The invention relates to an electric lamp with a bulb having an ignition zone, at least one electrode extending in the ignition zone, and the lamp comprising a bulb neck connected to the ignition zone At least one current supply device connected to the electrode is embedded in the bulb neck, and the electrode extends outward from the bulb neck. The invention also relates to a method of manufacturing an electric lamp. [Prior Art] ® In the case where the size of the lamp is kept the same or even smaller or the cooler in the illuminator is small, a member having a large heat load can be set while developing a discharge lamp and a halogen lamp which are generally high in power. . In such lamps, a typical current supply component consists of molybdenum which begins to oxidize at temperatures above about 3 50 °C. Since the system with the current carrying pin and the current carrying foil is embedded, for example, in the quartz glass of the bulb, there is no room for expansion of the bulky molybdenum oxide. In this way, the lamp is prematurely faulty due to cracks in the rod or even due to the bursting of the lamp. A lamp is known from DE 699 27 574 T2, in which a protective layer is formed on the outer current conductor and the current carrying foil connected to the current conductor. This protective layer is formed only as a thin layer of about 4 to 6 micrometers thick and is composed of, for example, chromium. Since the capillary is formed between the inner wall of the bulb neck and the current carrying foil, the outwardly extending current carrying pin, etc., the protective layer must extend over the entire length of the current carrying pin and must also be in the current carrying foil. The exposed part of the area extends. The application of the above protective layer is laborious. In addition, the cost of -5-200926257 required for such an application process is also high, and the method of application is hazardous to health due to the materials used to create the protective layer. Again, the protective layer must be applied to the current carrying foil and current carrying pins prior to the melting process. Since this document only has a capillary phenomenon between the inner wall of the bulb neck and the current carrying foil, the outer side of the current carrying pin, and the protective layer applied to the current carrying foil and the current carrying pin during the melting process, It is easy - and often unpredictable "whether or not a sufficient oxidative protection can be produced by the protective layer after the melting process". Since the material of the protective layer will also melt when melted, it is unpredictable to produce a sufficient oxidative protection more clearly. SUMMARY OF THE INVENTION An object of the present invention is to design an electric lamp and a method of manufacturing the same, in which the oxidation protection of the current-carrying parts of the electric lamp has been improved and this can be achieved with less difficulty. The above object is achieved by a lamp having the features of claim 1 and a method having the features of claim 9 of the patent application.电 The electric lamp of the present invention includes a bulb having an ignition zone. At least one electrode extends in the ignition zone. Additionally, the electric lamp includes at least one bulb neck that is coupled to the ignition zone. A current supply device is embedded in the bulb neck in a regional manner and is electrically connected to the electrodes extending into the ignition zone and the bulb neck. The electrode additionally extends outward from the bulb neck. A terminal-side hollow region is formed on an end of the bulb neck away from the ignition zone. At least a portion of the hollow region is infiltrated with a sealing material when viewed in the longitudinal direction of the current supply device so that a portion of the current supply device extending into the neck of the bulb is protected by oxidation from -6 to 200926257. Further, a layer is formed on the sealing material at least in a regional manner so that oxygen cannot enter the portion of the current supply device that extends into the neck of the bulb to achieve a protective function. Therefore, the electric lamp includes, in addition to the sealing material, another layer which at least greatly reduces the oxidation and the permeability of oxygen. With this arrangement of the lamp, the oxidation protection of the portion of the current supply device that extends into the neck of the bulb can be improved. The same effective oxidation protection can be achieved in a much more cost-effective manner than in the prior art. In addition, €1 ^ avoids the use of environmentally hazardous materials and does not require additional extra steps when applying the sealing material. It is preferable to use a material which can be used for other purposes in the manufacture of an electric lamp as the sealing material. Thus, this can also reduce costs. The electrode refers to the anode and cathode of a discharge lamp. Similarly, a white woven filament of an incandescent lamp (especially a halogen incandescent lamp) can be described with the guise of an electrode. The current supply means can be embedded in the bulb neck, in particular by melting and/or pressing of the material of the bulb neck in a suitable position. It is particularly preferable that the hollow portion of the bulb neck formed on the terminal side can be intruded with the sealing material only after the embedding process. Therefore, it is no longer necessary to perform coating on the current supply device before the melting process as in the prior art, and it is desirable in the subsequent melting process to distribute the coating for the fusion at the desired position. In an advantageous embodiment, the sealing material can be applied with certainty and accuracy when the pressing process has ended and the geometry of the hollow zone is known and no longer changes. 200926257 The space between the inner wall of the bulb neck and the outer side of the current supply device is filled with the sealing material as viewed perpendicular to the longitudinal direction of the current supply device. The intermediate zone, as produced by the prior art, will not reoccur. Undesirable thin positions are therefore also such that these thin positions greatly increase the risk of oxygen passing through. When viewed in the radial direction, the hollow region is completely formed by the sealing material. On one side of the burning zone of the neck press zone. When viewed in the longitudinal direction of the bulb neck and thus also in the longitudinal direction of the current Ο, at least a portion of the dip in the longitudinal direction extending over a shorter length is sufficient to ensure improved and less costly protection. In addition, the sealing material can be applied more easily and less frequently by the specificity of the hollow zone. The length and inner end of the hollow zone are preferably bordered by the end of the pressurizing zone. The thickness of the sealing material, and in particular in the radial direction, is greater than the radial dimension of the current carrying pin of the current supply. In particular, the thickness of the ® material is at least half of the current carrying pin of the current supply. The radial extent of the sealing material is therefore much larger than the radius of the pin of the current supply. In particular, the periphery of the current supply means is surrounded by the sealing material in the region of the pin. The outer side of the current carrying pin and the bulb neck limit the radial distance between the hollow areas to be much greater than the distance between the outer side of the current carrying pin and the inner wall outside the hollow area. Therefore, during the bulb and the fused cooling, the hollow region, particularly the hollow region which is not formed in the bulb neck, is preferably completely the same. Especially full. Keep away from the hollow area of the supply device to make the position of the oxygen, which is better than the double-current current carrying the current of the sealing material, and the light-filled component air area of the inner wall of the sealing material, -8- 200926257 In particular, the neck of the tubular bulb is hollow. This is particularly suitable when a bulb having a tubular shape is used, the hollow zone is a small recessed area formed around the carrier pin during the pressing process. The sealing material is appropriately set in a range of the shape of the cork. The diameter of the hollow zone is also the diameter in the hollow zone 'this diameter is greater than (especially at least) the diameter of the current carrying pin of the device. This special bulb is in the discharge lamp of the neck. However, in the hollow zone where the halogen should be. The sealing material is particularly advantageous in the case of a protective gas. For example, argon can be used as a design to make it particularly effective to prevent the entry of oxygen when the sealing material is present. Further improvement is achieved in Ο, especially in applying the expectation. The sealing material is preferably a high temperature resistant material having a temperature resistance of more than 550 ° C, preferably; 800 ° C ° when the sealing material is an inorganic cerium, Cerastii® can be used as The sealing material may also be a metal foam. The sealing material may be foamed and has aluminum particulate heat. The material is expanded into a discharge region of a metal bubble to form a hollow neck discharge lamp. The hollow zone is formed in the form of a current and due to the sealing material in the form of a hollow cork - times the current supply at the location is suitable for an incandescent lamp having a tubular shape It can be formed in a relatively atmospheric atmosphere and applied to the hollow region as a shielding gas. When such oxygen is discharged and, when applied, the protective effect of oxidation can seal the material, and the non-adhesive material can be avoided. The adhesive is preferably at 600 ° C, especially when it is larger than the i-bond material. E.g, . The preferred design is, . The hollow region is completely filled by the addition of the sealing material. -9- 200926257 The current supply device comprises a current carrying foil which is completely embedded in the bulb neck and connected to the electrode. Additionally, the current supply means includes a current carrying pin that is coupled to the current carrying foil in the interior of the bulb neck and extends outwardly from the bulb neck over the hollow region of the bulb neck. The sealing material is formed in a longitudinal direction of the current supply means, spaced apart from the connection area between the current carrying foil and the current carrying pin, without being in contact. Preferably, the sealing material is formed around the current carrying pin only in the periphery. The current carrying foil is therefore disposed in the bulb neck without the sealing material. The connection between the current carrying foil ® and the current carrying pin is in particular a soldering area and therefore does not come into contact with the material used for the connection. Thus, the sealing material can be applied much more easily and less frequently, since the application of the coating becomes difficult in the prior art, particularly due to the different shapes of the current carrying foil and the current carrying pin. In an advantageous arrangement of the invention, it is no longer necessary to provide the sealing material in the sensible region. The protective layer is preferably formed in the ignition region of the bulb before the oxygen enters. On the area. Therefore, it is preferable to form another protective layer on the outer side to prevent entry of oxygen. The location of application of this protective layer can be determined simply and without difficulty and ensures better protection against oxygen ingress. The protective layer and the sealing material for preventing entry of oxygen are preferably formed of different materials, respectively. This layer is formed in particular on the region of the sealing material which is protruded from the hollow region. With this arrangement, the planar extent of the layer as well as the layer thickness can be easily changed and optimized for -10-200926257. The protective layer for preventing oxygen from entering the current supply means is preferably formed directly on the sealing material. No other materials or other layers are disposed between the layer and the sealing material. However, it is also possible in principle not to apply the layer and the sealing material directly adjacently but to form an intermediate layer between them. Preferably, the protective layer for preventing the ingress of oxygen comprises at least a component of a poim imide. The layer may also be comprised of at least a ceramic fiber material in its composition. For example, the material Tyre anno Coat of UBE Industries can be used here. This layer is preferably formed of a material which is stable at temperatures up to 500 ° C. Preferably, the bulb has at least two bulb necks that face each other and terminate in the ignition zone. The electric lamp can be formed by a discharge lamp having a pedestal on one side. The electric lamp can also be formed by a lamp having a base on both sides. ^ The lamp is preferably formed by a discharge lamp, but can also be formed by a halogen incandescent lamp. In the method of manufacturing an electric lamp of the present invention, at least one of the electrodes extends in an area to the ignition zone of the bulb and is mounted in a zone manner in a bulb neck connected to the ignition zone and connected to a current supply means. The current supply device is embedded in the bulb neck in a regional manner and must extend beyond the bulb neck such that the current supply device extends outwardly through the hollow side of the bulb neck. The hollow region of the bulb neck is at least regionally interposed with a sealing material when viewed in the longitudinal direction of the current supply device such that the portion of the current supply device -11-200926257 that extends into the neck of the bulb is oxidatively protected. In the method of manufacturing an electric lamp of the present invention, at least a layer is formed on the sealing material in a region so that oxygen does not enter the portion of the current supply device that extends into the neck of the bulb. By such a manufacturing method, a better oxidation protection can be achieved with less trouble and cost. In the process, with this method and the materials selected, the impact on the environment is negligible compared to when using chromium. The portion of the current supply that extends into the neck of the bulb and the extension of the electrode. The portion that extends into the neck of the bulb is preferably embedded in the neck of the bulb by fusion and/or pressing of the material of the bulb neck. The sealing material is applied to the hollow area only after the current supply means and the electrodes are buried in the bulb neck in a regional manner. The sealing material is applied only in a step after the embedding process, so that the sealing material can be mounted more appropriately and surely. Thus, the oxidation protection can be greatly improved. Preferably, the sealing material is applied such that a space formed between the inner wall of the bulb neck and the outer side of the current supply means is completely filled by the sealing material when viewed perpendicular to the longitudinal direction of the current supply means. . Preferably, the entire hollow region is completely filled with the sealing material. Therefore, the presence of a large air zone can be avoided, and at least the amount of oxygen entering can be greatly reduced. The hollow zone is formed only on the side of the press zone remote from the ignition zone. Thus, only a small volume can exist to penetrate the sealing material at least in a regional manner. Therefore, the sealing material can be easily applied and then applied in a sufficient amount to improve the oxidation protection. -12- 200926257 The sealing material is applied to the hollow zone in a particularly advantageous manner under the atmosphere of a protective gas. It has been shown to be particularly advantageous that with the sealing material, it is possible to prevent oxygen from intruding into the neck of the bulb for more than 500 hours at a temperature of about 500 °C. By virtue of this particular function of the sealing material, which is preferably caused by the material composition and dimensions and amount of the sealing material, the operational applicability of the lamp can be greatly improved. The advantageous configuration of the electric lamp of the present invention can also be considered as an advantageous manner of the manufacturing method of the present invention. The invention will be described in detail below with reference to the embodiments in the drawings. [Embodiment] A lamp I formed by a discharge lamp is shown in Fig. 1. Fig. 1 shows a cutaway view in the upper region of the lamp I and a view in the lower region. In the present embodiment, the lamp I forms a high power lamp having a lamp power of, for example, 1 20,000 watts. The electric lamp I has a bulb 1 which includes an abdomen-shaped central portion' with a bulb neck 2 and another bulb neck 3 attached to the opposite sides of the upper jaw. This bulb 1 is formed in a single piece, and a discharge zone 4 is formed in the interior of the central portion as an ignition zone. The first electrode 5' extends in the discharge region 4, which is formed in the form of a rod in this embodiment. The first electrode 5 is electrically and mechanically connected to the current supply means 6, 7. The electrode 5 is made of tungsten or a material containing tungsten. The current supply means comprises a current carrying foil 6 formed of molybdenum or a material containing molybdenum and additionally forming a sealing foil when hermetically fused into the bulb neck 2. Further, the current supply means comprises a current carrying pin 7, which is also rod-shaped and composed of, for example, molybdenum or a material containing molybdenum. The second electrode 8 is arranged on the facing side in a suitable manner, which is likewise formed in a rod-like manner and extends into the discharge zone 4. Furthermore, the second electrode 8 is likewise embedded in the second bulb neck 3 at least in a regional manner and is electrically and mechanically connected to the current supply devices 9, 10, which are similar to the bulb neck 2 The current supply devices 6, 7 are formed. The current carrying pin 10 and the current carrying foil 9 of the current supply device are shown in the drawing. 〇 In this embodiment, the lamp I is provided with a pedestal on both sides. However, it is also possible to provide a discharge lamp having a pedestal on one side. Similarly, the lamp I can also be formed with a halogen incandescent lamp. The current carrying foil 6 and the current carrying pin 7 extending from the bulb neck 2 are welded to a connection location 13. A hollow region 11 is formed on the end 21 of the bulb neck 2 remote from the discharge region 4. Since the bulb 2 is designed as a tube in this embodiment, the cross section of the hollow region 11 is substantially circular. The longitudinal axis A of the bulb neck 2 substantially corresponds to the longitudinal direction of the current supply means 6, 7 and therefore also corresponds to the longitudinal axis A of the electrode 5 and the current carrying pin 7. The current carrying pin 7 is disposed substantially coaxially with the longitudinal axis of the hollow region n, wherein the longitudinal axis of the hollow region 11 corresponds to the longitudinal axis A of the bulb neck 2. A state in which the lamp I has been produced is shown in Fig. 1, in which the base is still mounted on the end side. This means that the current supply means 6, 7 are fused in the bulb neck and the material of the bulb neck 2 is pressed into a press section 22. Thus, the current carrying foil 6 is hermetically disposed in the bulb neck 2. The press section 22 has only a portion of -14-200926257 extending through the entire length of the bulb neck 2 and terminating at the lower end of the hollow region, i.e., terminating at the end of the hollow region u facing the connection position 13, the hollow region 11 It is completely filled with a sealing material 12. This sealing material 12' is formed so that a portion of the current supply means 6, 7 extending into the bulb neck 2 can be subjected to oxidation protection. The sealing material 12 may have an inorganic bonding material with a temperature resistance greater than 8 〇 (rc. However, a metal foam may also be provided as the sealing material 12. The hollow region 11 extends only to one position of the bulb neck 2, which is The connection position 13 is spaced apart. The sealing material 丨2 is therefore not in contact with the connection position i 3 and therefore also not in contact with the current carrying foil 6. The longitudinal distance is indicated by reference numeral 1. Further 'current carrying pin 7 has a diameter dl which is much smaller than the diameter d2 of the hollow zone π. The thickness of the sealing material ι2 is from the outer side of the current carrying pin 7 to the inner wall of the bulb neck 2 bounded by the hollow zone It is determined that this thickness is greater than (especially much larger) the radius of the current carrying pin 7 ((dl)/2). As can be seen from Fig. 1, the sealing material 12 only surrounds the current carrying pin 7 around. The material 12 is only broken into the hollow zone u after the embedding process (i.e., after the bulb neck 2 is fused and pressed into the press zone 22). The radial extent of the hollow zone 11 is therefore greater than the material of the bulb neck 2 In the area of the connection position 13, The capillary between the flow carrying foil 6, and the current carrying pin 7 in the press zone 22 is much larger, which is formed during the fusion process and subsequent cooling of -15-200926257. It is not shown in the region of the bulb neck 3. The cutaway view shows a side view of the lamp I viewed from the outside. The arrangement of the lamp I in the bulb neck 3 is similar to the arrangement in the bulb neck 2. For example, the hollow zone 14 forms a radius for the axis A The area of r is shown here. Here, the hollow zone 14 is formed on one end 31 of the bulb neck 3 remote from the discharge zone 4. The hollow zone 同样4 also extends only to a press zone 32. The hollow zone 11 is on the longitudinal axis A Viewed in the direction from the edge of the rear end of the bulb neck 2 to the beginning of the press section 22. In a similar manner, the size of the hollow zone 14 must be set in the bulb neck 3, in order to make the lamp I, The electrode 5 and the current supply means 6, 7 are to be inserted into the tubular bulb neck 2. Then, the press zone 22 is produced, at which time the bulb neck 2 is heated at a suitable position and the quartz glass material is fused. Pressing a suitable position on the bulb neck 2 a process for achieving a hermetic fusion of the current carrying foil 6. The bulb neck 2 is then cooled and, due to the different expansion of the material, an unshown capillary can be formed, in particular, at the connection location 13 and the current carrying Around the pin 7. The sealing material 12 is applied to the hollow zone 11 only after cooling. The manufacture of the lamp I is carried out in the same manner in the region of the bulb neck 3. The application of the sealing material 12 is in a protective gas The atmosphere is removed (for example, argon). The oxygen removal effect achieved by the sealing material 12 is sufficient for the temperature on the current supply device 6'7 to last at least 5 hours for at least 5 -16-16 - 200926257 . The corresponding situation also applies to the area of the bulb neck 3. If an inorganic bonding material (e.g., Cerastil®) is used as the sealing material 1 2 ', the bonding material can also be used to apply the susceptor to the lamp 1. When the lamp I is arranged as a halogen incandescent lamp, it is preferred to apply or mount the sealing material 12 in the hollow zone simultaneously or at least temporarily simultaneously with the mounting step of the susceptor. The manner shown in the arrangement of the lamp I in the region of the bulb neck 2 can be similarly used in the arrangement or mode of operation in the bulb neck 3, or can also be used when the lamp I ® has the second bulb described above Corresponding to the second bulb neck of the lamp I. As can be discerned from Fig. 1, the hollow regions n and 14 are formed on the end facing the discharge region 4. The sealing material 12 can also form a seal in the form of a cork by the environment and dimensions of the hollow zones 11 and 14. According to Fig. 1, the sealing material 12 extends beyond the edge of the rear edge or the rear end 21. As shown in Fig. 1, another protective ruthenium layer 16 is formed on the sealing material 12 so that oxygen cannot enter the current supply devices 6, 7, 9 and 10. This layer 16 is formed directly on the surface 15 of the sealing material 12, wherein the surface 15 is away from the ignition zone 4 and faces the upper side of the environment. In this embodiment, the sealing material 12 has to be applied to the hollow zone u. The sealing material 12 extends outwardly on the edge of the rear end 21 with some arcuate curvature. This layer 16 is also applied to the edge of the rear end 21 after it is applied directly to the outwardly extending surface 丨5. The sealing material 12 is thus completely covered by the layer 16 on the exposed surface 15. -17- 200926257 This layer 16 is applied to the surface 15 particularly after the sealing material 12 is completely formed in the hollow region u. This layer 16 can be composed of a polyamide or ceramic fiber material and in particular has a temperature stability up to a temperature of 5001. By this layer 16, the oxygen permeability can be made smaller and the time of the possible axis jump can be delayed. The improvement of the high temperature protection at 500 ° C can be achieved by the layer 16 to obtain a 15% to 20% improvement. This ensures the availability of a discharge lamp and a halogen incandescent lamp with all of the base.
