このような高圧ガス放電ランプは、ヨーロッパ特許出願第381279号により既に 知られている。 Such a high-pressure gas discharge lamp is already known from European Patent Application No. 381279.
【０００３】 このような既知のランプでは幾何学系的な形状にもよるが、前の点灯期間によ り依然として熱い間にランプを始動するために高電圧が印加される場合に前記外 球内の前記電流供給導体間にフラッシュオーバーを生ずることが不可能ではない ことが見出されていた。従ってランプはさらに冷却されるまで始動させることが 出来ず低い電圧では始動には充分ではなかった。ランプの幾何学的な形状は様々 な要因、この中でもランプにより消費される電力により決定されるであろう。In such known lamps, depending on the geometrical shape, the interior of the outer bulb is affected when a high voltage is applied to start the lamp while it is still hot due to the previous lighting period. It has been found that it is not impossible to cause a flashover between the current supply conductors of the. Therefore, the lamp could not be started until it was cooled further, and the low voltage was not sufficient for starting. The geometrical shape of the lamp will be determined by various factors, among which the power consumed by the lamp.
【０００４】[0004]
本考案は冒頭に記載のような高圧放電ランプにおいて外球内のフラッシュオー バーの危険を防止する高圧放電ランプを提供することを目的とする。 It is an object of the present invention to provide a high pressure discharge lamp as described at the beginning which prevents the danger of flashover in the outer bulb.
【０００５】 本考案によれば、この目的は第一電流リードを発光管から導出する領域で絶縁 物により囲み、この絶縁物を発光管に固定することにより実現される。According to the invention, this object is achieved by enclosing the first current lead in an area leading from the arc tube with an insulator and fixing this insulator to the arc tube.
【０００６】 この手段により、一方の前記第二の電流供給導体の露出部分と他方の前記第一 の電流リードとの間の間隔が前記第一の電流リードの周囲の絶縁物がない時より もより大きい。ランプを始動する代わりにフラッシュオーバーを生ずるような印 加電圧の危険をこのようにしてかなり減少させる。By this means, the distance between the exposed part of the second current supply conductor on the one hand and the first current lead on the other hand is greater than when there is no insulation around the first current lead. Greater than Instead of starting the lamp, the risk of applied voltage causing a flashover is thus considerably reduced.
【０００７】 例えばセラミック管のような適切な絶縁物を、例えば接着剤、エナメルのよう なものを用いて前記発光管に固定する。石英ガラスのようなガラス管を例えば融 着により前記発光管に接続してもよい。A suitable insulator, eg a ceramic tube, is fixed to the arc tube, eg with an adhesive, enamel or the like. A glass tube such as quartz glass may be connected to the arc tube, for example by fusion.
【０００８】[0008]
本考案によるランプの実施例を側面図に示す。 An embodiment of a lamp according to the present invention is shown in a side view.
【０００９】 図に示す高圧ガス放電ランプは第一端部３で封着シール２を有する真空気密外 球１を備える。接点５を備える口金４を前記外球の前記第一端部の周囲に固定す る。発光管６を真空気密状に封入しイオン性充填物及び第一電流リード８及び第 二電流リード９に接続される電極７を備え、前記電流リードは各々前記外球１の 前記第一端部３から離れ又は隣接するようにして前記発光管から導出され、前記 発光管は前記外球内に収容される。前記口金４の接点５に各々接続される第一電 流供給導体１０及び第二電流供給導体１１は前記外球１の前記第一端部３の前記 シール２を通り、前記第一電流リード８及び第二電流リード９に延びる。この場 合前記第二電流供給導体１１の部分は前記外球１の内側に絶縁物１２により取り 囲まれ、この絶縁物は前記外球１の前記シール２内に固定される。The high-pressure gas discharge lamp shown in the figure comprises a vacuum-tight envelope 1 having a sealing seal 2 at a first end 3. A base 4 having a contact 5 is fixed around the first end of the outer sphere. The arc tube 6 is sealed in a vacuum-tight manner and is provided with an ionic filling and an electrode 7 connected to the first current lead 8 and the second current lead 9. The current leads are respectively the first end portions of the outer bulb 1. It is led out from the arc tube so as to be separated from or adjacent to the arc tube 3, and the arc tube is housed in the outer bulb. The first current supply conductor 10 and the second current supply conductor 11 which are respectively connected to the contacts 5 of the base 4 pass through the seal 2 of the first end portion 3 of the outer bulb 1 and the first current lead 8 And to the second current lead 9. In this case, the part of the second current supply conductor 11 is surrounded inside the outer sphere 1 by an insulator 12, which is fixed in the seal 2 of the outer sphere 1.
【００１０】 前記第一電流リード８は絶縁物１３により取り囲まれ、この絶縁物は前記発光 管６に、前記発光管６から前記第一電流リード８が導出する領域で固定される。 図に示す絶縁物は前記発光管に融着される石英ガラス管である。The first current lead 8 is surrounded by an insulator 13, which is fixed to the arc tube 6 in a region where the first current lead 8 is led out from the arc tube 6. The insulator shown in the figure is a quartz glass tube fused to the arc tube.
【００１１】 図において前記第二電流供給導体１１の露出部分と前記第一電流リード８の露 出部分との間の間隔は、本考案による手段を用いない間隔ａは本考案による手段 を用いた場合の間隔ｂのように増大する。この結果高温状態でのランプの再始動 の間に電流供給導体間のフラッシュオーバーは防止される。露出された部分の間 の間隔の同様な広さは既知のランプの幾何学的な形状では可能ではなかった。こ れは前記絶縁物１２を前記第二電流供給導体１１の折り曲げ部(bend)を越えて延 長することが出来ないためである。さらにより長い絶縁物１２を使用することは 破断の危険を含み、ランプの製造をより複雑にすることとなる。In the figure, the distance between the exposed portion of the second current supply conductor 11 and the exposed portion of the first current lead 8 does not use the means according to the present invention, and the distance a uses the means according to the present invention. It increases like the interval b in the case. As a result, flashover between current supply conductors is prevented during lamp restart at high temperatures. A similar amount of spacing between exposed parts was not possible with known lamp geometries. This is because the insulator 12 cannot extend beyond the bent portion of the second current supply conductor 11. The use of even longer insulation 12 involves the risk of breakage and makes lamp manufacture more complex.
【００１２】 石英ガラス（シリカガラス）の代わりに９５重量％以上の二酸化シリコンSiO を含有するソーダ石灰ガラスのようなガラス又は硬質ガラス(hard glass)を前記 絶縁物１３として用いることも出来る。Instead of quartz glass (silica glass), glass such as soda lime glass containing 95% by weight or more of silicon dioxide SiO 2 or hard glass can be used as the insulator 13.
【００１３】 前記発光管６は充填物として例えば臭化物希土類元素、水銀、臭化水銀及び沃 化水銀の何れか少なくとも一つと、沃化セシウム及び例えば８０ミリバール(mba r)の分圧のアルゴン／クリプトンのような希ガスを封入する。本考案によるラン プは電極間の間隔は、例えば１５mmよりも大きく２０mmまたはそれ以上であり、 例えば4000Ｗのような数ｋＷの電力を消費する。冷却状態で例えば2000Ｖで始動 することが可能であるが、しかし直前のランプの消灯の結果ランプ内の圧力が比 較的高い場合に数十ｋＶの電圧、例えば６５ｋＶの電圧を再度ランプを始動する ためには必要である。The arc tube 6 is filled with at least one of rare earth elements such as bromide, mercury, mercury bromide and mercury iodide, cesium iodide and argon / krypton with a partial pressure of, for example, 80 mbar. Noble gas such as is enclosed. In the lamp according to the present invention, the distance between the electrodes is, for example, greater than 15 mm and 20 mm or more, and consumes several kW of electric power such as 4000 W. It is possible to start the lamp in the cooled state, for example at 2000V, but if the pressure in the lamp is relatively high as a result of the extinction of the lamp immediately before, restart the lamp with a voltage of several tens of kV, for example 65kV It is necessary for this.
