Das mindestens eine Lampengefäß weist eine lichtdurchlässige, elektrisch leitfähige Schicht auf, die zumindest den Entladungsraum der Lampe umschließt. Unter dem Entladungsraum wird hier nur der für die Gasentladung in der Lampe wirksame Teil des Innenraums des mindestens einen Lampengefäßes verstanden. Die Beschichtung erstreckt sich daher zumindest über diejenigen Gefäßteile des mindestens einen Lampengefäßes, die das Entladungsplasma umschließen. Durch die Beschichtung des mindestens einen Lampengefäßes wird beim Betrieb der Entladungslampe an einer mittelfrequenten Wechselspannung die von dem im Lampengefäß eingeschlossenen Entladungsplasma emittierte mittelfrequente elektromagnetische Strahlung um mehr als 50 Dezibel geschwächt. Eine Störung des Rundfunkempfanges findet daher selbst dann nicht statt, wenn die Entladungslampe in der Nähe der Antenne eines Rundfunkempfängers an einem elektronischen Betriebsgerät betrieben wird.The discharge lamp of the lighting system according to the invention has at least a translucent lamp vessel covering the discharge space of the discharge lamp encloses a lamp and electrical connections for their voltage supply. The at least one lamp vessel has a translucent, electrical conductive layer that at least encloses the discharge space of the lamp. Below the discharge space is only the one for gas discharge in the Lamp effective part of the interior of the at least one lamp vessel understood.

Über die Meßelektroden wird der Schicht ein Strom vorgegebener Stromstärke aufgeprägt und der Spannungsabfall über den Meßelektroden mittels eines Galvanometers bestimmt. Der Quotient aus dem gemessenen Spannungsabfall und der Stromstärke des aufgeprägten Stromes ergibt den spezifischen Oberflächenwiderstand der zu messenden Schicht. Der spezifische Oberflächenwiderstand der Schicht ist unabhängig von der Größe des quadratischen Flächenauschnittes der Schicht. Er hängt nur von dem Quotienten aus dem spezifischen elektrischen Widerstand des Schichtmaterials und der Schichtdicke ab. Die Einheit des spezifischen Oberflächenwiderstandes wird üblicherweise mit Ohm pro Square bezeichnet.The specific surface resistance of an electrically conductive layer is usually measured with the help of two flat electrodes, which are applied to the layer to be measured so that they are facing each other are arranged opposite one another.

A current is given to the layer via the measuring electrodes Current intensity and the voltage drop across the measuring electrodes determined by means of a galvanometer. The quotient from the measured Voltage drop and the current strength of the impressed current results the specific surface resistance of the layer to be measured. The specific one The surface resistance of the layer is independent of the size the square area of the layer. It just depends on that Quotients from the specific electrical resistance of the layer material and the layer thickness. The unit of surface resistivity is usually referred to as ohms per square.

Bei dem besonders bevorzugten Ausführungsbeispiel der Erfindung handelt es sich um eine Entladungslampe, die vorwiegend gelbes, orangefarbenes oder rotes Licht emittiert. Die Schichtdicke der lichtdurchlässigen, elektrisch leitfähigen Schicht ist daher vorteilhafterweise so gewählt, daß das beschichtete Lampengefäß in dem Wellenlängenbereich von 550 nm bis 700 nm eine möglichst hohe Transparenz, das heißt, einen Transmissionskoeffizienten von größer als 0,8 besitzt. Die Dicke der lichtdurchlässigen, elektrisch leitfähigen Schicht muß nämlich einerseits hinreichend groß sein, um eine ausreichende elektrische Leitfähigkeit zu gewährleisten, und andererseits aber auch hinreichend klein sein, um noch eine ausreichende Lichtdurchlässigkeit aufzuweisen. Gemäß des besonders bevorzugten Ausführungsbeispiels der Erfindung ist die Entladungslampe als Neongasentladungslampe ausgebildet. Diese Lampe erzeugt vorwiegend orangefarbenes oder rotes Licht. Sie kann daher vorteilhafterweise als Bestandteil eines Beleuchtungssystems in einem Kraftfahrzeug, zur Erzeugung des Blinklichtes oder des Schluß- und/oder Bremslichtes, verwendet werden.The translucent, electrically conductive layer is advantageously as ITO layer, that is, formed as an indium tin oxide layer. In which particularly preferred embodiment of the invention a discharge lamp that is predominantly yellow, orange or red Light emitted.

Das mindestens eine Lampengefäß besitzt vorteilhafterweise ein zylindrisches Gefäßteil und zwei in Richtung des Reflektors abgewinkelte Enden. Dadurch wird gewährleistet, daß die dunklen Enden der Entladungslampe, die mit den elektrischen Anschlüssen der Lampe ausgestattet sind, nicht sichtbar sind. Alternativ können die dunklen Enden der Entladungslampe auch in abgeschattete Bereiche der Beleuchtungsvorrichtung verlegt werden.The lighting system according to the invention has a discharge lamp and Operating device for the discharge lamp, the discharge lamp at least has a lamp vessel enclosing the discharge space of the lamp, which with a translucent, electrically conductive layer is provided, this Layer extends at least over the discharge space and to a predetermined one electrical reference potential, which is advantageously the circuit-internal ground potential of the control gear or the earth potential is connected. The aforementioned Features of the lighting system according to the invention ensure its satisfactory electromagnetic compatibility because of the discharge plasma the discharge lamp emits medium-frequency electromagnetic radiation is weakened by more than 50 decibels. The lighting system according to the invention additionally has a reflector. To have a high degree of light reflection achieve, the reflector of the lighting system according to the invention has a metallic or a metallized reflection surface. The reflector therefore also exercises a shielding effect on that of the discharge plasma in the discharge lamp generated electromagnetic radiation. It has turned out to be special proven advantageous, the reflector and possibly metallized parts of the lamp housing to improve the shielding also to the specified electrical To connect the reference potential. The layer thickness of the translucent, electrically conductive layer on the reflector or the interior of the Luminous wall areas of the at least one lamp vessel lower be carried out as on the wall areas of the at least facing away from the reflector a lamp vessel, and in this way the light transmission of the Reflector facing wall areas increases and the efficiency of the invention Lighting system can be improved.

Dadurch weisen diese Wandbereiche eine besonders hohe Transparenz für Licht mit einer Wellenlänge von 600 nm auf. Dieses Beleuchtungssystem eignet sich daher vorteilhafterweise zur Verwendung in einem Kraftfahrzeug zur Erzeugung des Schlußlichtes oder/und des Bremslichtes.In the particularly preferred embodiment of the lighting system according to the invention is the layer thickness of the translucent, electrically conductive Layer on the wall areas of the at least facing away from the reflector a lamp vessel 300 nm.

Die lichtdurchlässige, elektrisch leitfähige Schicht auf dem Außenkolben der Hochdruckentladungslampe ist mit dem schaltungsinternen Massepotential des Betriebsgerätes verbunden.The invention can also be applied to other types of discharge lamps, for example on low-pressure discharge lamps or on high-pressure discharge lamps and on lighting systems with a high-pressure discharge lamp such as one with a high pressure discharge lamp equipped automotive headlights can be applied. In particular in this case it is a single-sided high-pressure discharge lamp, which is a discharge vessel enclosed by a glass outer bulb has, the outer bulb with a translucent, electrically conductive layer - preferably an ITO layer which extends over the entire discharge space of the lamp. The High-pressure discharge lamp is preferably part of a motor vehicle headlight and is operated on an electronic control gear. The translucent, electrically conductive layer on the outer bulb The high-pressure discharge lamp is connected to the internal circuit potential connected to the control gear.
Anstelle einer ITO-Schicht können auch lichtdurchlässige, elektrisch leitende Schichten, die aus einem anderen Material, beispielsweise aus Zinnoxid SnO2 oder aus mit Fluor bzw. Antimon dotierten Zinnoxid SnO2:F bzw. SnO2:Sb bestehen, eingesetzt werden.Instead of an ITO layer, it is also possible to use translucent, electrically conductive layers which consist of another material, for example of tin oxide SnO 2 or of tin oxide SnO 2 : F or SnO 2 : Sb doped with fluorine or antimony.
