II. Darstellung der Erfindung II. Presentation of the invention

Es ist Aufgabe der Erfindung, eine alternative gattungsgemäße Hochdruckentladungslampe bereitzustellen, die während des Betriebs weißes Licht mit erhöhter Farbtemperatur emittiert bei vergleichbarer Maintenance und vergleichbarem Lichtstrom.It is an object of the invention to provide an alternative generic high-pressure discharge lamp which emits white light with increased color temperature during operation with comparable maintenance and comparable luminous flux.

Diese Aufgabe wird erfindungsgemäß durch eine Hochdruckentladungslampe mit den Merkmalen aus dem Patentanspruch 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Patentansprüchen beschrieben. Die erfindungsgemäße Hochdruckentladungslampe dient als Lichtquelle in Fahrzeugscheinwerfer und besitzt ein gasdicht verschlossenes Entladungsgefäß, das einen Entladungsraum aufweist, in dem Elektroden und eine quecksilberfreie Füllung zum Erzeugen einer Gasentladung eingeschlossen sind. Die Füllung enthält zumindest Xenon und Halogenide von Natrium, Scandium, Zink und Indium, wobei der Quotient aus dem molaren Anteil von Natrium und dem molaren Anteil von Scandium im Halogenidanteil der Füllung einen Wert im Bereich von 2 bis 3 besitzt. Erfindungsgemäß ist die Menge der Halogenide im Entladungsraum insgesamt auf einen Wert im Bereich von 8 bis 11 Mikrogramm pro 1 Kubikmillimeter des Entladungsraumvolumens reduziert und die Gewichtsanteile an Zinkhalogenid und Indiumhalogenid sind im Vergleich zum Stand der Technik deutlich erhöht, so dass der Wert für Zinkhalogenid im Bereich von 18 bis 23 Gewichtsprozent und der Wert für Indiumhalogenid im Bereich von 1 bis 3 Gewichtsprozent und bevorzugt im Bereich von 2 bis 3 Gewichtsprozent liegt, jeweils bezogen auf die gesamte Halogenidmenge im Entladungsraum. Zusätzlich liegt erfindungsgemäß der Kaltfülldruck, das heißt, der bei einer Temperatur von 25°C gemessene Druck, von Xenon im Entladungsraum im Wertebereich von 1,1 bis 1,5 Megapascal und bevorzugt im Bereich von 1,1 bis 1,4 Megapascal.This object is achieved by a high-pressure discharge lamp with the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims. The high-pressure discharge lamp according to the invention serves as a light source in vehicle headlights and has a gas-tight discharge vessel which has a discharge space in which electrodes and a mercury-free filling for generating a gas discharge are enclosed. The filling contains at least xenon and halides of sodium, scandium, zinc and indium, wherein the quotient of the molar proportion of sodium and the molar fraction of scandium in the halide content of the filling has a value in the range from 2 to 3. According to the invention, the total amount of halides in the discharge space is reduced to a value in the range of 8 to 11 micrograms per 1 cubic millimeter of the discharge space volume and the weight proportions of zinc halide and indium halide are significantly increased compared to the prior art, so that the value for zinc halide in the range from 18 to 23 weight percent and the indium halide value is in the range of 1 to 3 weight percent, and preferably in the range of 2 to 3 weight percent, based in each case on the total amount of halide in the discharge space. In addition, according to the invention, the cold filling pressure, that is to say the pressure measured at a temperature of 25.degree. C., of xenon in the discharge space is in the value range of 1.1 to 1.5 megapascals and preferably in the range of 1.1 to 1.4 megapascals.

Aufgrund der vorgenannten Merkmale emittiert die erfindungsgemäße Hochdruckentladungslampe während ihres Betriebs weißes Licht mit einer gegenüber der Hochdruckentladungslampe gemäß dem Stand der Technik um ca. 300 Kelvin auf ca. 4800 Kelvin erhöhten Farbtemperatur, während der von ihr erzeugte Lichtstrom und ihre Maintenance vergleichbar zur Hochdruckentladungslampe gemäß dem Stand der Technik sind.Due to the aforementioned features, the high-pressure discharge lamp according to the invention emits white light during its operation with a color temperature increased by about 300 Kelvin compared to the high-pressure discharge lamp according to the prior art, while the luminous flux produced by it and its maintenance comparable to the high-pressure discharge lamp according to the State of the art.

Außerdem hat die erfindungsgemäße Hochdruckentladungslampe die Vorteile, dass durch den vergleichsweise hohen Indiumhalogenidanteil ihre Anlaufphase verkürzt wird und durch den vergleichsweise geringen Kaltfülldruck von Xenon die Stabilität des Entladungsbogens gegenüber mechanischen Schwingungen erhöht wird sowie durch die vergleichsweise geringe Halogenidmenge im Entladungsraum eine homogenere Abbildung des Entladungsbogens im Fahrzeugscheinwerfer ermöglicht wird, weil die Abschattung oder Verzerrung durch nicht verdampfte Füllungskomponenten geringer ist. Der Begriff Anlaufphase bezeichnet die Betriebsphase der Hochdruckentladungslampe, die unmittelbar nach Zündung der Gasentladung beginnt und mit dem Erreichen eines stationären Betriebszustands der Hochdruckentladungslampe endet. Während der Anlaufphase verdampfen die Halogenide im Entladungsraum.In addition, the high-pressure discharge lamp according to the invention has the advantages that by the comparatively high Indiumhalogenidanteil their start-up phase is shortened and the stability of the discharge arc against mechanical vibrations is increased by the comparatively low cold pressure of xenon and by the comparatively small amount of halides in the discharge space a more homogeneous imaging of the discharge arc in the vehicle headlights is possible because the shading or distortion by non-vaporized filling components lower is. The term start-up phase refers to the operating phase of the high-pressure discharge lamp, which begins immediately after ignition of the gas discharge and ends with the achievement of a stationary operating state of the high-pressure discharge lamp. During the start-up phase, the halides evaporate in the discharge space.

Ferner hat die erfindungsgemäße Hochdruckentladungslampe eine ähnliche Brennspannung wie die Hochdruckentladungslampe gemäß dem Stand der Technik, weil der durch die höheren Zink- und Indiumhalogenidanteile verursachte Anstieg der Brennspannung durch den reduzierten Kaltfülldruck von Xenon bei der erfindungsgemäßen Hochdruckentladungslampe kompensiert wird. Der Begriff Brennspannung bezeichnet die elektrische Spannung, die sich nach dem Erreichen eines stationären Betriebszustands der Hochdruckentladungslampe zwischen den Elektroden bzw. über dem Entladungsbogen ausbildet. Sie entspricht der Betriebsspannung der Hochdruckentladungslampe.Furthermore, the high-pressure discharge lamp according to the invention has a similar burning voltage as the high-pressure discharge lamp according to the prior art, because the increase in the burning voltage caused by the higher zinc and indium halide components is compensated by the reduced cold filling pressure of xenon in the high-pressure discharge lamp according to the invention. The term burning voltage refers to the electrical voltage that forms after reaching a stationary operating state of the high-pressure discharge lamp between the electrodes or over the discharge arc. It corresponds to the operating voltage of the high-pressure discharge lamp.

Vorteilhafterweise sind die Halogenide im Entladungsraum der erfindungsgemäßen Hochdruckentladungslampe als Jodide ausgebildet. Jodide haben gegenüber anderen Halogeniden den Vorteil, dass sie chemisch weniger aggressiv sind und keine chemische Reaktion mit dem Material des Entladungsgefäßes verursachen.Advantageously, the halides are formed in the discharge space of the high-pressure discharge lamp according to the invention as iodides. Iodides have the advantage over other halides that they are less chemically aggressive and Do not cause a chemical reaction with the material of the discharge vessel.

Vorzugsweise werden in der erfindungsgemäßen Hochdruckentladungslampe die Halogenide Natriumjodid, Scandiumjodid und Zinkjodid sowie Indiumjodid verwendet. Die Summe der Anteile der vorgenannten Jodide ergibt vorzugsweise die gesamte Menge der Halogenide im Entladungsraum der erfindungsgemäßen Hochdruckentladungslampe. Es hat sich gezeigt, dass die vorgenannten Jodide vollkommen ausreichend sind, um weißes Licht zu erzeugen, das den gesetzlichen Anforderungen genügt, die an eine als Lichtquelle im Fahrzeugscheinwerfer einsetzbare Hochdruckentladungslampe gestellt werden.The halides sodium iodide, scandium iodide and zinc iodide and indium iodide are preferably used in the high-pressure discharge lamp according to the invention. The sum of the proportions of the abovementioned iodides preferably gives the total amount of halides in the discharge space of the high-pressure discharge lamp according to the invention. It has been found that the abovementioned iodides are completely sufficient to produce white light which meets the legal requirements which are imposed on a high-pressure discharge lamp which can be used as a light source in the vehicle headlight.

Vorzugsweise besitzt die Füllung der erfindungsgemäßen Hochdruckentladungslampe einen Anteil von Natriumhalogenid mit einem Wert im Bereich von 30 bis 40 Gewichtsprozent und einen Anteil von Scandiumhalogenid mit einem Wert im Bereich von 35 bis 45 Gewichtsprozent, jeweils bezogen auf die gesamte Menge der Halogenide im Entladungsraum.Preferably, the filling of the high-pressure discharge lamp according to the invention has a content of sodium halide with a value in the range of 30 to 40 weight percent and a proportion of scandium halide with a value in the range of 35 to 45 weight percent, each based on the total amount of halides in the discharge space.

Die Beschichtung 107 besteht aus dotiertem Zinnoxid, beispielsweise aus mit Fluor oder Antimon dotiertem Zinnoxid oder beispielsweise aus mit Bor und beziehungsweise oder Lithium dotiertem Zinnoxid. Diese Hochdruckentladungslampe wird in horizontaler Lage betrieben, das heißt, mit in einer horizontalen Ebene angeordneten Elektroden 11, 12, wobei die Lampe derart ausgerichtet ist, dass die Stromrückführung 17 unterhalb des Entladungsgefäßes 30 und des Außenkolbens 16 verläuft. Details dieser Beschichtung 107 sind in der EP 1 632 985 A1 beschrieben. Der Außenkolben 16 besteht aus Quarzglas, das mit Ultraviolette Strahlung absorbierenden Stoffen dotiert ist, wie zum Beispiel Ceroxid und Titanoxid. Geeignete Glaszusammensetzungen für das Außenkolbenglas sind in der WO 94/28576 A1 und in der WO 2012/072398 A1 offenbart.The current return 17 facing surface region of the discharge vessel 10 is provided with a translucent, provided electrically conductive coating 107, which serves as a starting aid. The coating 107 consists of doped tin oxide, for example of tin oxide doped with fluorine or antimony or, for example, boron and / or lithium doped tin oxide. This high-pressure discharge lamp is operated in a horizontal position, that is, with arranged in a horizontal plane electrodes 11, 12, wherein the lamp is oriented such that the current return path 17 extends below the discharge vessel 30 and the outer bulb 16. Details of this coating 107 are in the EP 1 632 985 A1 described. The outer bulb 16 is made of quartz glass doped with ultraviolet radiation absorbing materials such as cerium oxide and titanium oxide.

Die in dem Entladungsgefäß eingeschlossene Füllung besteht aus Xenon mit einem Kaltfülldruck, das heißt einem bei einer Temperatur von 25°C gemessenen Fülldruck, von 1,3 Megapascal, und den Jodiden von Natrium, Scandium, Zink und Indium. Die Brennspannung der Lampe beträgt ca. 42 Volt. Ihre Farbtemperatur liegt bei ca. 4800 Kelvin. Die Gesamtmenge der Halogenide bzw. Jodide der Metalle Natrium, Scandium, Zink und Indium in der Füllung beträgt 220 µg entsprechend 9,78 µg/mm3, das heißt 9,78 Mikrogramm pro 1 Kubikmillimeter Entladungsraumvolumen, wobei die Gewichtsanteile der Jodide der Metalle Natrium-, Scandium, Zink und Indium bezogen auf die gesamte Menge der Halogenide wie folgt lauten: Natriumjodid (NaI): 35,75 Gewichtsprozent, entsprechend einer Füllmenge von 3,50 µg/mm3 Scandiumjodid (ScI3): 40,4 Gewichtsprozent, entsprechend einer Füllmenge von 3,95 µg/mm3 Zinkjodid (ZnI2) : 21,2 Gewichtsprozent, entsprechend einer Füllmenge von 2,07 µg/mm3 Indiumjodid (InI): 2,65 Gewichtsprozent, entsprechend einer Füllmenge von 0,26 µg/mm3 The filling enclosed in the discharge vessel consists of xenon with a cold filling pressure, that is to say a filling pressure of 1.3 megapascal measured at a temperature of 25 ° C., and the iodides of sodium, scandium, zinc and indium. The burning voltage of the lamp is approx. 42 volts. Its color temperature is about 4800 Kelvin. The total amount of halides or iodides of the metals sodium, scandium, zinc and indium in the filling is 220 μg, corresponding to 9.78 μg / mm 3 , ie 9.78 micrograms per 1 cubic millimeter discharge volume, the weight proportions of the iodides of the metals being sodium -, scandium, zinc and indium based on the total amount of halides are as follows: Sodium iodide (NaI): 35.75 weight percent, corresponding to a load of 3.50 μg / mm 3 Scandium iodide (ScI 3 ): 40.4 weight percent, corresponding to a capacity of 3.95 μg / mm 3 Zinc iodide (ZnI 2 ): 21.2 weight percent, corresponding to a load of 2.07 micrograms / mm 3 Indium iodide (InI): 2.65% by weight, corresponding to a filling amount of 0.26 μg / mm 3

Aus den oben genannten Anteilen von Natriumjodid und Scandiumjodid ergeben sich für die Anteile von Natrium und Scandium die Werte 12,0 µg und 9,4 µg in der Füllung. Die vorgenannten Anteile von Natrium und Scandium entsprechen 0,52 10-3 Mol Natrium und 0,21 10-3 Mol Scandium in der Füllung. Der Quotient der molaren Anteile von Natrium und Scandium besitzt daher einen Wert von 2,5 und das Molverhältnis von Natrium zu Scandium in der Füllung ist daher 2,5:1. Die Füllung der Hochdruckentladungslampe enthält außer den vorgenannten Bestandteilen keine weiteren Komponenten, sodass die Summe der Gewichtsanteile von Natriumjodid, Scandiumjodid, Zinkjodid und Indiumjodid die gesamte Menge, das heißt 100 Gewichtsprozent, der Halogenide im Entladungsraum 106 ergibt.From the above-mentioned proportions of sodium iodide and scandium iodide, the proportions of sodium and scandium are 12.0 μg and 9.4 μg in the filling. The abovementioned proportions of sodium and scandium correspond to 0.52 10 -3 mol of sodium and 0.21 10 -3 mol of scandium in the filling. The quotient of the molar proportions of sodium and scandium therefore has a value of 2.5 and the molar ratio of sodium to scandium in the filling is therefore 2.5: 1. The filling of the high-pressure discharge lamp contains no further components apart from the abovementioned constituents, so that the sum of the proportions by weight of sodium iodide, scandium iodide, zinc iodide and indium iodide gives the total amount, that is to say 100 percent by weight, of the halides in the discharge space 106.

Die erfindungsgemäße Halogen-Metalldampf-Hochdruckentladungslampe wird unmittelbar nach der Zündung der Gasentladung im Entladungsgefäß mit dem drei- bis fünffachen ihrer Nennleistung bzw. ihres Nennstroms betrieben, um ein schnelles Verdampfen der Metallhalogenide in der ionisierbaren Füllung zu gewährleisten. Unmittelbar nach dem Zünden der Gasentladung wird diese fast ausschließlich vom Xenon getragen, da nur das Xenon zu diesem Zeitpunkt gasförmig im Entladungsgefäß vorliegt. Die Hochdruckentladungslampe arbeitet zu diesem Zeitpunkt und während der so genannten Anlaufphase, während der die Metallhalogenide der ionisierbaren Füllung in die Dampfphase übergehen, daher wie eine Xenon-Höchstdruckentladungslampe, bei der sowohl die Lichtemission als auch die elektrische Eigenschaften der Entladung, insbesondere der Spannungsabfall über der Entladungsstrecke, allein vom Xenon und dem Elektrodenabstand bestimmt werden. Erst wenn die oben genannten Jodide der ionisierbaren Füllung verdampft sind und diese an der Entladung teilnehmen, ist ein quasistationärer Betriebszustand der Lampe erreicht, in dem die Lampe mit ihrer Nennleistung von 35 Watt und einer Brennspannung von 42 Volt betrieben wird. Der Begriff Brennspannung bezeichnet demzufolge die Betriebsspannung der Hochdruckentladungslampe im quasistationären Betrieb.The high-pressure metal halide high-pressure discharge lamp according to the invention is operated immediately after the ignition of the gas discharge in the discharge vessel at three to five times its rated power or rated current in order to ensure rapid vaporization of the metal halides in the ionizable filling. Immediately after ignition of the gas discharge, it is almost exclusively carried by the xenon, since only the xenon at this time is present in the discharge vessel in gaseous form. The high-pressure discharge lamp operates at this time and during the so-called start-up phase, during which the metal halides of the ionizable filling in the vapor phase, so like a high-pressure xenon discharge lamp, in which both the light emission and the electrical properties of the discharge, in particular the voltage drop across the Discharge range, to be determined solely by the xenon and the electrode distance. Only when the above-mentioned iodides of the ionizable filling are vaporized and they participate in the discharge, a quasi-stationary operating state of the lamp is reached, in which the lamp is operated with its nominal power of 35 watts and a burning voltage of 42 volts. The term burning voltage therefore refers to the operating voltage of the high-pressure discharge lamp in quasi-stationary operation.

Die Erfindung beschränkt sich nicht auf das oben näher erläuterte Ausführungsbeispiel. Beispielsweise kann der Lampensockel derart ausgebildet sein, dass er in seinem Innenraum zusätzlich zur Zündvorrichtung auch Komponenten der Betriebsvorrichtung oder sogar die komplette Betriebsvorrichtung für die Hochdruckentladungslampe enthält. Alternativ kann der Lampensockel auch ohne Zündvorrichtung ausgebildet sein und die Zündvorrichtung außerhalb des Lampensockels als Bestandteil eines externen Betriebsgeräts der Hochdruckentladungslampe ausgebildet sein.The invention is not limited to the embodiment explained in more detail above. For example, the lamp cap can be designed such that it contains in its interior in addition to the ignition device and components of the operating device or even the entire operating device for the high pressure discharge lamp. Alternatively, the lamp cap can also be configured without an ignition device and the ignition device can be formed outside the lamp cap as part of an external operating device of the high-pressure discharge lamp.
