The invention relates to an electric lamp with a bulb having an ignition space 'with at least one electrode extending therein'. The bulb further comprises a bulb neck connected to the ignition space, wherein the bulb is buried At least one current guiding device connected to the electrode is disposed, which extends outward from the bulb neck. The invention further relates to a method of manufacturing an electric lamp. [Prior Art] At the same time, discharge lamps and halogen lamps having a relatively large power are developed and the size of the lamps is kept the same or smaller or the degree of cooling in the illuminators is small, so that a large amount of thermal load of the members can be stopped. The general part for conducting current is composed, for example, of molybdenum in such a lamp, and molybdenum starts to oxidize at a temperature higher than about 350 °C. Since the above system and a current carrier pin and a current carrier foil are embedded in the quartz glass of the lamp, there is no room for expansion of the bulky molybdenum oxide. This can cause the lamp to fail early due to a shaft jump or even a lamp burst. An electric lamp is known from DE 6 99 27 5 74 T2, in which a protective layer is formed on the outer current conductor and the current carrier foil connected to the current conductor. This protective layer forms only a thin layer of about 4 microns to 6 microns and is composed, for example, of chromium. Due to the capillary phenomenon formed between the inner wall of the bulb neck and the current carrier foil, and portions of the outwardly extending current carrier pin, the protective layer must extend over the entire length of the current carrier pin and must also An exposed portion of the current carrier foil extends over a portion of the area. The installation of the above protective layer is laborious. In addition, the cost of this installation is relatively high and the method of installation can be hazardous to health due to the materials used in the production of the layer. In addition, the protective layer must be applied to the current 200915377 carrier foil and the current carrier pin prior to the fusing process. Since the above document forms a capillary phenomenon between the inner wall of the bulb neck and the current carrier foil and the outer side of the current carrier pin, the inner wall of the bulb neck and the current carrier foil and the current carrier pin are applied. The capillary phenomenon is formed between the upper protective layers only when the fusion process occurs, and it is less predictable and generally unpredictable whether the protective layer can produce a sufficient oxide protective layer after the fusing process. Since the material of the protective layer will also melt during the fusing process, it is not expected whether a sufficient oxide protective layer can be additionally defined. SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric lamp and a method of manufacturing such an electric lamp, wherein the oxide protection of the portion carrying the current in the electric lamp can be improved and this can be achieved in a less expensive manner. The above object is achieved by an electric lamp having the features of claim 1 and a manufacturing method having the feature of claim 16 of the patent application. The electric lamp of the present invention includes a bulb having an ignition space. At least one electrode extends in the ignition space. Additionally, the bulb includes at least one bulb neck that is coupled to the ignition space. A current guiding device is embedded in the bulb neck in a regional manner, which is electrically connected to the ignition space and the electrode extending in the bulb neck. This current guiding device is additionally extended by the neck of the bulb. A hollow region on the end side is formed on one end of the bulb neck away from the ignition space. At least a portion of the hollow region is infiltrated with a sealing material when viewed in the longitudinal direction of the current guiding device to achieve oxidative protection of the portion of the current guiding device that extends in the neck of the bulb. With this arrangement of the lamp, the oxidative protection of the -6 200915377 portion of the current guiding device extending in the neck of the bulb can be improved. An equally effective oxidative protection can be achieved more cost-effectively in a much simpler manner than in the prior art. Furthermore, the use of various environmentally harmful substances can be avoided and no additional extra steps are required when applying the sealing material. It is preferable to use a material which can be used for other purposes when the lamp is manufactured as the sealing material. As a result, the cost can also be reduced. By electrode is meant, for example, the anode and cathode of a discharge lamp. Similarly, the entanglement of the electrodes can also refer to an incandescent spiral filament of an incandescent lamp, particularly a halogen incandescent lamp.
該電流導引裝置特別是可藉由適當位置上之燈泡頸之材 料之熔合及/或壓榨而埋置於燈泡頸中。特別有利的是：燈 '泡頸之末端側上所形成的中空區只有在該埋置過程之後才 可以該密封材料來塡入。因此，像先前技術中，，在該熔合過 手呈之前必須在該電流導引裝置上進行塗層且在隨後之熔合 過程中期望該熔接用的塗層分佈在所期望的位置上，，已不 需要。在本發明之一種有利的形式中，該壓榨過程已結束 且該中空區之幾何佈置已爲人所知以及不再改變時，則以 很明確且準確的方式來施加該密封材料。 該燈泡頸之內壁和該電流導引裝置之外側之間的中空區 之空出空間在垂直於該電流導引裝置之縱向中觀看時較佳 是完全以該密封材料來塡入。因此，像先前技術中的大型 中間區不會發生。不期望之薄的位置亦不會發生，這些薄 的位置在先前技術中甚至須設置，其會使氧侵入的危險性 大大地提高。於是，特別是在徑向中觀看時，該中空區完 全以該密封材料來塡入。 200915377 該中空區較佳是只形成在該燈泡頸之壓榨區域之遠離該 點燃空間之此側上。在該燈泡頸之縱向且亦是在該電流導 引裝置之縱向中觀看時，一在縱向中以較短的長度而延伸 之中空區之至少一部分以塡料來塡入時即已足夠能以較少 的耗費來使氧化保護作用獲得改良且可確保成本較有利。 此外，藉由該中空區之上述特定的位置，則亦可較簡易且 耗費較少地施加該密封材料。 該中空區之長度以及內部末端較佳是以該壓榨區之遠離 該點燃空間之末端來限制。 該密封材料之厚度且特別是徑向中的範圍較佳是大於該 電流導引裝置之電流載體銷之徑向尺寸。特別是該密封材 料之厚度至少是該電流導引裝置之電流載體銷之半徑之二 倍大。該密封材料之徑向範圍因此較佳是較電流導引裝置 之電流載體銷之半徑大很多。特別是該電流導引裝置的周 圍側面在該電流載體銷之區域中是由該密封材料所圍繞 著。 該電流載體銷之外側和該燈泡頸之以該中空區爲邊界的 內壁之間的徑向距離較電流載體銷之外側和該中空區外部 (因此是在一已形成的毛細現象之區域中）之該燈泡頸之內 壁之間的距離大很多。特別是在該燈泡冷卻以及各組件熔 合期間該中空區表示該燈泡頸中並未具有已形成的空氣 區，反之，該中空區特別是由管形的燈泡頸之空的末端區 所形成。這在放電燈中特別是與管形的燈泡頸有關。在鹵 素白熾燈中，中空區的形成是在壓榨過程中產生，這樣會 在電流載體銷之周圍出現小的凹口。 200915377 該密封材料特別是以軟木塞的形式來形成且由於該中空 區的造型而可適當地設定尺寸。 中空區的直徑且因此亦是該中空區中該軟木塞形式之密 封材料之直徑大於（特別是至少二倍）該電流導引裝置在該 位置處之電流載體銷之直徑。這在放電燈中特別是與管形 的燈泡頸有關。然而，在鹵素白熾燈中亦可形成相對應的 中空區。 該密封材料在保護氣體之大氣中可特別有利地封入至該 # 中空區中。例如，可設置氬氣以作爲該保護氣體。藉由此 % 種方式，則已存在的氧可特別有效地排出且在施加該密封 材料時可防止氧之進入。於是，氧化保護作用可進一步獲 得改良。特別是在施加該密封材料時，可防止不期望的氧 之侵入。 該密封材料較佳是一種耐高溫的黏合材料。該黏合材料 之耐溫性可設計成大於450°C，特別是大於600°C，特別佳 時是大於800°C。當該密封材料是一種無機黏合材料時是有 利的。例如，可使用CerastU®作爲黏合材料。 ~ 該密封材料亦可以是一種金屬泡沬。此處建議該密封材 料較佳是可泡沫化且具有鋁粒子。藉由該密封材料之加 熱，則該材料可膨脹成一種金屬泡沬且完全塡滿該中空區。 該電流導引裝置包括一電流載體箔，其完全埋置於該燈 泡頸中且與該電極相連接。此外，該電流導引裝置包括一 電流載體銷，其在該燈泡頸內部中是與該電流載體箔相連 接且在該燈泡頸之中空區上由該燈泡頸向外延伸。該密封 材料在該電流導引裝置之縱向中觀看時形成在電流載體箔 -9- 200915377 和電流載體銷之間且與該連接區相隔開而未接觸。因此， 該密封材料較佳是只在周圍側面圍繞著該電流載體銷而形 成。該電流載體箔因此以未具備該密封材料的方式而配置 在該燈泡頸中。電流載體箔和電流載體銷之間的連接區（其 特別是一種焊接區）因此是在與該連接材料未接觸的情況下 形成。 於是，可以簡易很多且耗費較少的方式來施加該密封材 料，此乃因特別是由於電流載體箔和電流載體銷之不同的 造型而使先前技術中明確地施加該塗層時成爲很不容易。 " 正好在此一敏感的區域中，在本發明的有利的佈置中已不 需要再設置該密封材料。 燈泡較佳是具有至少二個燈泡頸，其相面對地注入至該 點燃空間上。 該電燈可以一側有基座的放電燈來形成。該電燈亦可設 計成二側都設有基座的燈。 該電燈較佳是形成一種放電燈，亦可設置成鹵素白熾燈。 在本發明之一種電燈的製造方法中，至少一電極以區域 ';; 方式在燈泡之點燃空間中延伸以及以區域方式在一連接至 該點燃空間之燈泡頸中延伸而形成且與一電流導引裝置相 連接。此電流導引裝置以區域方式埋置在燈泡頸中且亦須 安裝在燈泡頸中，使此電流導引裝置經由燈泡頸之末端側 之中空區而向外延伸。此中空區在該燈泡頸中在該電流導 引裝置之縱向中觀看時至少以區域方式而以一種密封材料 來塡入，以使該電流導引裝置之在燈泡頸中延伸之部分可 受到氧化保護。藉由電燈之上述製造方法，則能以耗費少 -10- 200915377 且成本有利的方式來達成較佳的氧化保護作用。在此種製 造方法中’可藉由此方法和所選取的材料而不再發生健康 上的危害現象。 該電流導引裝置之在燈泡中延伸的部分以及該電極之在 燈泡中延伸的部分可藉由該燈泡頸之材料之熔合及/或壓榨 而埋置於該燈泡頸中。該密封材料只有在以區域方式埋置 & %流導引裝置和該電極之後才可在該燈泡頸中埋置於該 中空區中。在一在該埋置過程之後的步驟中施加該密封材 料，這樣可較適當且較明確地施加該密封材料。於是，亦 可使氧化保護作用大大地獲得改良。 較佳是須施加該密封材料，使該中空區之在該燈泡頸之 內壁和該電流導引裝置之外側之間所形成的空出空間在垂 直於該電流導引裝置之縱向中觀看時完全以該密封材料來 塡入。 整個中空區較佳是完全以該密封材料來塡入。因此可防 止較大的空氣區的出現，且至少可使氧的進入量大大地下 降。 該中空區只形成在該壓榨區之一遠離該點燃空間之此側 上。於是’只需較少的體積至少以區域方式而以該密封材 料來塡入。因此’可容易地施加該密封材料且隨後施加一 種足夠的量以達成較佳的氧化保護作用。 該密封材料在一特別有利的方式中在保護氣體之大氣下 施加在該中空區中。 藉由該密封材料，在溫度大約50(TC時可持續超過500小 時以防止氧侵入至該燈泡頸中，這樣是特別有利的。該密 -11- 200915377 封材料之此種特殊的功能可藉由該密封材料之材料成份和 維度及數量來達成，藉由此種特殊功能’則該電燈之操作 上的適當性可大大地提高。 本發明之電燈之有利的佈置方式可視爲本發明之製造方 法之有利的佈置方式。 以下將依據圖式來說明本發明的實施例。 【實施方式】 第1圖中顯示一種以放電燈來形成之電燈I。此圖顯示該 電燈I之切面圖的上部區域以及切面圖的下部區域。 f "\ X 此電燈I在本實施例中以大功率之燈來形成，燈功率例 如可以是1 2 0 0瓦。 此電燈I具有一燈泡1，其包括一種腹部形的中央部，此 中央部上在相對的側面上連接著一燈泡頸2和一燈泡頸3。 燈泡1以單件形式來形成且一放電空間4形成在該中央部 的內部中以作爲點燃空間。第一電極5在該放電空間4中 延伸，本實施例中第一電極5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導引裝置6，7相連接。 '' 電極5在本實施例中由鎢或含鎢之材料所製成。 該電流導引裝置包含一電流載體箔6，其由鉬或含鉬之材 料所形成且在氣密地熔接至燈泡頸2中時另外形成一密封 箔。此外，該電流導引裝置包含一電流載體銷7，其同樣以 棒形方式來形成且例如由鉬或含鉬之材料所構成。 以相對應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在該放電空間4中延伸。此外，第 二電極8同樣至少以區域方式而埋置於第二燈泡頸3中且 -12- 200915377 在電性上和機械上是與電流導引裝置9，i〇相連接，此電 流導引裝置9，1 0類似於電流導引裝置6，7而形成於燈泡 頸2中。例如，電流導引裝置之電流載體銷1 0和電流載體 箱9顯示於圖中。 本實施例中該電燈I在二側設有基座。然而，亦可設計 一種在單側設有基座的放電燈。同樣’電燈I亦可以鹵素白 熾燈來形成。 電流載體箔6和由該燈泡頸2延伸而出的電流載體銷7 焊接在一連接位置1 3處。一中空區1 1形成在該燈泡頸2 之遠離該放電空間4之末端2 1上。本實施例中由於該燈泡 2在其基本佈置中設計成管狀’則該中空區1 1形成一種橫 切面是圓形的中空區1 1。該燈泡2之縱軸A基本上對應於 電流引線6，7之縱方向且因此亦對應於電極5和電流載體 銷7之縱軸A。電流載體銷7是與該中空區1 1之縱軸成共 軸而配置著，其中該中空區1 1之縱軸即爲該燈泡頸2之縱 軸A。 第1圖中顯示該電燈I處於已製成的狀態中，其中末端 側安裝著基座。這表示：電流導引裝置6，7熔接於該燈泡 頸中且燈泡頸2之材料壓榨至一壓榨區2 2中。於是，電流 載體箔6以氣密方式配置於燈泡頸2中。該壓榨區22只有 一部分在該燈泡頸2之整個長度上延伸且終止於該中空區 1 1之下方以及因此亦終止於該中空區1 1之與該連接位置13 相面對的末端。 本實施例中，該中空區11中完全以一種密封材料1 2來 塡入。此密封材料1 2用來使電流導引裝置6，7之在燈泡頸 -13- 200915377 2中延伸的部分可受到氧化保護作用。 該密封材料1 2可以是一種抗溫度性大於 合材料。然而，該密封材料12亦可以是一 該中空區1 1只延伸至該燈泡頸2之一位 是與該連接位置1 3相隔開。該密封材料1 2 位置1 3相接觸且因此亦未與電流載體箔6 離以元件符號1來表示。 此外，該電流載體銷7具有一種直徑dl 1 1之直徑d 2小很多。該密封材料12之厚 體銷7之外側至該燈泡頸2之以該中空區 之距離’此厚度因此大於（特別是大很多）該 半徑（（dl )/2)。 由第1圖可辨認出’該密封材料12只在 電流載體銷7。 該密封材料1 2只有在該埋置過程之後且 頸2焊接且壓榨之後才在該壓榨區22中塡 中。 該中空區11之徑向尺寸因此較焊接過程 程中在該燈泡頸2之材料和該連接位置i 3 載體箔6、以及壓榨區22中該電流載體銷 毛細區大很多。 在燈泡頸3之區域中未顯示切面圖而是 外部看到的側視圖。該電燈I在燈泡頸3中 燈泡頸2之區域中的佈置。例如，中空區 的半徑是r。此處，該中空區14亦形成在 800°C之無機黏 種金屬泡沬。 置處，此位置處 因此未與該連接 相接觸。縱向距 ，其較該中空區 度是指該電流載 1 1爲邊界之內壁 電流載體銷7之 周圍側包圍著該 因此是在該燈泡 入至該中空區11 及隨後的冷卻過 之區域中該電流 7之間所形成的 顯不該電燈I由 之佈置類似於在 1 4對A軸所具有 該燈泡頸3之一 -14- 200915377 遠離該放電空間4之末端31上。該中空區14同樣只延伸至 一壓榨區32。 該中空區1 1在縱軸A之方向中觀看時由燈泡頸2之後端 21之邊緣開始且最多到達該壓榨區22之起始端。 以類似的方式而在燈泡頸3中設定該中空區1 4之尺寸。 因此，在製造電燈I時，電極5和電流導引裝置6，7插 入於管形的燈泡頸2中。然後，產生該壓榨區22，此時該 燈泡頸2在相對應的位置上加熱且使該石英玻璃材料熔 化。此外，在該燈泡頸2之適當的位置上進行一種壓榨過 程’以便使該電流載體箔達成氣密的焊接。然後，使該燈 泡頸2冷卻且特別是可在該連接位置1 3和電流載體銷7之 周圍由於不同的材料膨脹性而形成未顯示的毛細現象。 只有在冷卻之後該密封材料12才可施加至該中空區n 中。以相對應的方式在該燈泡頸3之區域中製成該電燈t。 施加該密封材料12是在—種保護氣體（例如，氬）的大氣 下進行。The current guiding means can be embedded in the bulb neck, in particular, by fusion and/or pressing of the material of the bulb neck at a suitable location. It is particularly advantageous if the hollow zone formed on the end side of the bulb 'the neck can only be invaded by the sealing material after the embedding process. Therefore, as in the prior art, it is necessary to perform coating on the current guiding device before the fusion hand is applied and it is desirable to distribute the coating for welding in a desired position during the subsequent fusion process. No need. In an advantageous form of the invention, the pressing process has ended and the geometric arrangement of the hollow zone is known and no longer changed, the sealing material is applied in a very clear and accurate manner. The vacant space of the hollow region between the inner wall of the bulb neck and the outer side of the current guiding means is preferably completely immersed in the sealing material when viewed in a longitudinal direction perpendicular to the current guiding means. Therefore, a large intermediate zone like the prior art does not occur. Undesirably thin locations do not occur, and these thin locations are even required to be provided in the prior art, which greatly increases the risk of oxygen intrusion. Thus, particularly when viewed in the radial direction, the hollow region is completely penetrated by the sealing material. 200915377 Preferably, the hollow region is formed only on the side of the press region of the bulb neck away from the ignition space. When viewed in the longitudinal direction of the bulb neck and also in the longitudinal direction of the current guiding device, at least a portion of the hollow region extending in a shorter length in the longitudinal direction is sufficient to be inserted by the dip material Less cost is required to improve oxidation protection and to ensure cost is advantageous. Further, by the above specific position of the hollow region, the sealing material can be applied more easily and with less effort. The length of the hollow zone and the inner end are preferably limited by the end of the press zone remote from the ignition space. The thickness of the sealing material, and particularly the extent in the radial direction, is preferably greater than the radial dimension of the current carrier pin of the current guiding device. In particular, the thickness of the sealing material is at least twice as large as the radius of the current carrier pin of the current guiding device. The radial extent of the sealing material is therefore preferably much larger than the radius of the current carrier pin of the current guiding device. In particular, the peripheral side of the current guiding device is surrounded by the sealing material in the region of the current carrier pin. The radial distance between the outer side of the current carrier pin and the inner wall of the bulb neck bounded by the hollow region is greater than the outer side of the current carrier pin and the outside of the hollow region (and thus in the region of the formed capillary phenomenon) The distance between the inner walls of the bulb neck is much larger. In particular, during cooling of the bulb and fusion of the components, the hollow region indicates that the bulb neck does not have an air zone that has been formed, and conversely, the hollow region is formed, inter alia, by an empty end region of the tubular bulb neck. This is in particular in the discharge lamp associated with a tubular bulb neck. In halogen incandescent lamps, the formation of the hollow regions is created during the pressing process, which results in small notches around the current carrier pins. 200915377 The sealing material is formed in particular in the form of a cork and can be appropriately sized due to the shape of the hollow zone. The diameter of the hollow zone and thus also the diameter of the sealing material in the form of the cork in the hollow zone is greater than (particularly at least twice) the diameter of the current carrier pin of the current guiding device at that location. This is especially relevant in the discharge lamp in relation to the tubular bulb neck. However, a corresponding hollow region can also be formed in the halogen incandescent lamp. The sealing material can be enclosed in the # hollow zone in a particularly advantageous manner in the atmosphere of the shielding gas. For example, argon gas may be provided as the shielding gas. By this way, the existing oxygen can be discharged particularly efficiently and the entry of oxygen can be prevented when the sealing material is applied. Thus, the oxidation protection can be further improved. In particular, when the sealing material is applied, intrusion of undesired oxygen can be prevented. The sealing material is preferably a high temperature resistant bonding material. The temperature resistance of the adhesive material can be designed to be greater than 450 ° C, especially greater than 600 ° C, and particularly preferably greater than 800 ° C. It is advantageous when the sealing material is an inorganic bonding material. For example, CerastU® can be used as a bonding material. ~ The sealing material can also be a metal foam. It is suggested herein that the sealing material is preferably foamable and has aluminum particles. By heating the sealing material, the material expands into a metal foam and completely fills the hollow region. The current directing means comprises a current carrier foil which is completely embedded in the bulb neck and is connected to the electrode. Additionally, the current directing means includes a current carrier pin that is coupled to the current carrier 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 between the current carrier foil -9-200915377 and the current carrier pin when viewed in the longitudinal direction of the current guiding device and is not in contact with the connecting region. Therefore, the sealing material is preferably formed only around the side of the current carrier pin. The current carrier foil is thus disposed in the bulb neck so as not to have the sealing material. The connection zone between the current carrier foil and the current carrier pin, which in particular a soldering zone, is thus formed without contact with the connecting material. Thus, the sealing material can be applied in a much simpler and less expensive manner, since it is not easy to apply the coating clearly in the prior art, in particular due to the different shapes of the current carrier foil and the current carrier pin. . " Just in this sensitive area, it is no longer necessary to provide the sealing material in an advantageous arrangement of the invention. Preferably, the bulb has at least two bulb necks that face each other into the ignition space. The lamp can be formed by a discharge lamp having a pedestal on one side. The lamp can also be designed as a lamp with a base on both sides. The electric lamp preferably forms a discharge lamp or can be arranged as a halogen incandescent lamp. In a method of manufacturing an electric lamp according to the present invention, at least one electrode is formed in a region of the light bulb and extends in a region manner in a bulb neck connected to the ignition space to form a current guide. The lead devices are connected. The current guiding device is embedded in the bulb neck in a regional manner and must also be mounted in the bulb neck such that the current guiding device extends outwardly through the hollow region on the distal end side of the bulb neck. When viewed in the longitudinal direction of the current guiding device, the hollow region is penetrated at least in a regional manner with a sealing material so that the portion of the current guiding device that extends in the bulb neck can be oxidized. protection. By the above-described manufacturing method of the electric lamp, it is possible to achieve better oxidation protection in a cost-effective manner with a small cost of -10-200915377. In this method of manufacture, the health hazard can no longer occur by this method and the materials selected. The portion of the current guiding device that extends in the bulb and the portion of the electrode that extends in the bulb can be embedded in the bulb neck by fusion and/or pressing of the material of the bulb neck. The sealing material can be embedded in the hollow region of the bulb neck only after the & % flow guiding device and the electrode are embedded in the region. The sealing material is applied in a step subsequent to the embedding process so that the sealing material can be applied more appropriately and more specifically. Thus, the oxidation protection can be greatly improved. Preferably, the sealing material is applied such that an empty space formed between the inner wall of the bulb neck and the outer side of the current guiding device is viewed in a longitudinal direction perpendicular to the current guiding device. It is completely penetrated by the sealing material. Preferably, the entire hollow region is completely intrusive with the sealing material. Therefore, the occurrence of a large air zone can be prevented, and at least the amount of oxygen entering can be greatly reduced. The hollow zone is formed only on one side of the press zone remote from the ignition space. Thus, it takes only a small volume to penetrate the sealing material at least in a regional manner. Thus, the sealing material can be easily applied and then applied in a sufficient amount to achieve better oxidation protection. In a particularly advantageous manner, the sealing material is applied in the hollow zone under the atmosphere of a protective gas. With the sealing material, it is particularly advantageous to prevent oxygen from intruding into the bulb neck at a temperature of about 50 (TC for more than 500 hours. This special function of the seal material can be borrowed. The material composition and the dimensions and the quantity of the sealing material are achieved, and the operational suitability of the electric lamp can be greatly improved by the special function. The advantageous arrangement of the electric lamp of the invention can be regarded as the manufacture of the invention. Advantageous Arrangement of the Method Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Embodiment] An electric lamp I formed by a discharge lamp is shown in Fig. 1. This figure shows the upper part of the cutaway view of the electric lamp I. The area and the lower area of the cutaway view. f "\ X This lamp I is formed in the present embodiment with a high power lamp, for example, the lamp power can be 1 2 0 0 watts. The lamp I has a bulb 1 including a central portion of the abdomen, on the opposite side, a bulb neck 2 and a bulb neck 3 are connected to the opposite side. The bulb 1 is formed in a single piece and a discharge space 4 is formed in the central portion. The first electrode 5 extends in the discharge space 4. In the present embodiment, the first electrode 5 is formed in the form of a rod. The first electrode 5 is electrically and mechanically electrically conductive. The lead means 6, 7 are connected. '' The electrode 5 is made of tungsten or a material containing tungsten in this embodiment. The current guiding means comprises a current carrier foil 6, which is formed of molybdenum or a material containing molybdenum. In addition, a sealing foil is additionally formed when it is welded in the bulb neck 2. In addition, the current guiding device comprises a current carrier pin 7, which is likewise formed in a rod-shaped manner and is for example made of molybdenum or a material containing molybdenum. The second electrode 8 is arranged on the opposite side in a corresponding manner, which is likewise formed in a rod-shaped manner and extends in the discharge space 4. Furthermore, the second electrode 8 is likewise buried at least in a regional manner. Placed in the second bulb neck 3 and -12-200915377 is electrically and mechanically connected to the current guiding device 9, i〇, which is similar to the current guiding device 6, 7 is formed in the bulb neck 2. For example, the current of the current guiding device The carrier pin 10 and the current carrier box 9 are shown in the figure. In this embodiment, the lamp I is provided with a pedestal on both sides. However, it is also possible to design a discharge lamp having a pedestal on one side. It can also be formed by a halogen incandescent lamp. The current carrier foil 6 and the current carrier pin 7 extending from the bulb neck 2 are welded at a connection position 13. A hollow zone 1 1 is formed in the bulb neck 2 away from the discharge. At the end 2 1 of the space 4. In this embodiment, since the bulb 2 is designed to be tubular in its basic arrangement, the hollow region 11 forms a hollow region 11 having a circular cross section. The longitudinal axis of the bulb 2 A substantially corresponds to the longitudinal direction of the current leads 6, 7 and therefore also to the longitudinal axis A of the electrode 5 and the current carrier pin 7. The current carrier pin 7 is disposed coaxially with the longitudinal axis of the hollow region 1 1 , wherein the longitudinal axis of the hollow region 11 is the longitudinal axis A of the bulb neck 2. Fig. 1 shows that the lamp I is in a state in which the base is mounted on the end side. This means that the current guiding means 6, 7 are welded in the bulb neck and the material of the bulb neck 2 is pressed into a press zone 22. Thus, the current carrier foil 6 is disposed in the bulb neck 2 in an airtight manner. Only a portion of the press zone 22 extends over the entire length of the bulb neck 2 and terminates below the hollow zone 1 1 and thus also terminates at the end of the hollow zone 11 facing the connection location 13. In the present embodiment, the hollow region 11 is completely infused with a sealing material 12 . This sealing material 12 is used to protect the portion of the current guiding device 6, 7 which extends in the bulb neck - 13 - 200915377 2 from oxidation protection. The sealing material 12 may be a temperature resistant material greater than the composite material. However, the sealing material 12 may also be a hollow region 11 extending only to a position of the bulb neck 2 spaced apart from the connection position 13. The sealing material 1 2 is in contact with the position 13 and is therefore also not distinguished from the current carrier foil 6 by the symbol 1 . Furthermore, the current carrier pin 7 has a diameter d2 which is much smaller than the diameter d1. The thickness of the outer side of the thick body pin 7 of the sealing material 12 to the bulb neck 2 is thus greater than (particularly much larger) the radius ((dl)/2). As can be seen from Fig. 1, the sealing material 12 is only on the current carrier pin 7. The sealing material 12 is only smashed in the press zone 22 after the embedding process and after the neck 2 is welded and pressed. The radial extent of the hollow zone 11 is therefore much greater than the material of the bulb neck 2 and the connection location i 3 of the carrier foil 6 and the press zone 22 during the soldering process. A cutaway view is not shown in the area of the bulb neck 3 but a side view seen externally. The arrangement of the lamp I in the region of the bulb neck 2 in the bulb neck 2. For example, the radius of the hollow zone is r. Here, the hollow region 14 is also formed of an inorganic viscous metal foam at 800 °C. Placed, this position is therefore not in contact with the connection. The longitudinal distance, which is the inner wall of the inner wall of the current carrier 11 is surrounded by the current side, and thus the bulb is inserted into the hollow zone 11 and the subsequently cooled region. The lamp 1 formed between the currents 7 is arranged similarly to the end 31 of the pair of bulb necks 1 - 14 - 200915377 away from the discharge space 4 on the A-axis. The hollow zone 14 also extends only to a press zone 32. The hollow zone 11 begins at the edge of the rear end 21 of the bulb neck 2 when viewed in the direction of the longitudinal axis A and reaches at most the beginning of the press section 22. The size of the hollow zone 14 is set in the bulb neck 3 in a similar manner. Therefore, in the manufacture of the lamp I, the electrode 5 and the current guiding means 6, 7 are 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 corresponding position and the quartz glass material is melted. Further, a pressing process is performed at an appropriate position of the bulb neck 2 to achieve a hermetic welding of the current carrier foil. Then, the bulb neck 2 is cooled and, in particular, an unshown capillary phenomenon can be formed around the connection position 13 and the current carrier pin 7 due to different material expandability. The sealing material 12 can be applied to the hollow zone n only after cooling. The electric lamp t is made in the region of the bulb neck 3 in a corresponding manner. The application of the sealing material 12 is carried out under the atmosphere of a protective gas (e.g., argon).
