Bei einer ersten Gruppe bevorzugter Ausführungsformen der erfindungsgemäßen Vorrichtung umfasst diese weiterhin einen Temperatursensor zum Messen der Temperatur des Funktionsbereiches. Der Temperatursensor dient bevorzugt zum unmittelbaren oder mittelbaren Messen der Temperatur des Funktionsbereiches. Das mittelbare Messen der Temperatur des Funktionsbereiches kann beispielsweise dadurch erfolgen, dass der Temperatursensor über einen Wärmeleiter mit dem Funktionsbereich verbunden ist. Das Mittel zur Temperaturregelung ist durch eine Temperaturregelungselektronik gebildet. Der Temperatursensor ist elektrisch mit der Temperaturregelungselektronik verbunden, sodass die Temperatur am Funktionsbereich durch die Temperaturregelungselektronik regelbar ist. Bevorzugt ist die Temperaturregelungselektronik dazu ausgebildet, die mit dem Temperatursensor gemessene Temperatur auf einen vorgegebenen konstanten Wert zu regeln. Der Temperatursensor kann unmittelbar oder mittelbar mit der Temperaturregelungselektronik elektrisch verbunden sein. Die erfindungsgemäße Vorrichtung kann so ausgebildet sein, dass der Temperatursensor unmittelbar am Funktionsbereich anbringbar ist.

The temperature sensor is preferably used for direct or indirect measurement of the temperature of the functional area. The indirect measuring of the temperature of the functional area can take place, for example, by connecting the temperature sensor to the functional area via a heat conductor. The means for temperature control is formed by a temperature control electronics.

Bei der erfindungsgemäßen Vorrichtung ist der Transformatorkern zum Erwärmen des Funktionsbereiches ausgebildet, wofür der Transformatorkern Wärme leitend mit dem Funktionsbereich verbunden ist und wobei vorzugsweise die Vorrichtung weiterhin einen durch die Temperaturregelungselektronik steuerbaren elektronischen Schalter umfasst, der elektrisch mit der Sekundärwicklung verbunden ist. Der elektronische Schalter ist parallel zur Sekundärwicklung geschaltet. Ist der elektronische Schalter geöffnet bzw. hochohmig, so bewirkt der durch die Primärwicklung fließende Wechselstrom eine ständige Ummagnetisierung des Transformatorkernes mit den damit verbundenen Ummagnetisierungsverlusten, welche den Transformatorkern und folglich den Funktionsbereich erwärmen. Ist der elektronische Schalter geschlossen bzw. niederohmig, so ist die Spannung an der Sekundärwicklung nahezu Null bzw. sehr klein, sodass es trotz des durch die Primärwicklung fließenden Wechselstromes nur zu einer vernachlässigbaren Ummagnetisierung des Transformatorkernes mit den damit verbundenen Ummagnetisierungsverlusten kommt und der Transformatorkern kaum erwärmt wird.In the device according to the invention, the transformer core is designed for heating the functional area, for which the transformer core is conductively connected to the functional area and preferably the device further comprises an electronic switch controllable by the temperature control electronics, which is electrically connected to the secondary winding. The electronic switch is connected in parallel to the secondary winding. If the electronic switch is open or high-impedance, the alternating current flowing through the primary winding causes a constant remagnetization of the transformer core with the associated re-magnetization losses, which cause the Heat transformer core and thus the functional area. If the electronic switch is closed or low-resistance, then the voltage at the secondary winding is almost zero or very small, so that, despite the alternating current flowing through the primary winding, only a negligible magnetization reversal of the transformer core with the associated re-magnetization losses occurs and the transformer core hardly heats up becomes.

Die erfindungsgemäße Vorrichtung kann so ausgebildet sein, dass der Transformatorkern unmittelbar am Funktionsbereich anbringbar ist. Die erfindungsgemäße Vorrichtung kann aber auch so ausgebildet sein, dass der Transformatorkern beabstandet zum Funktionsbereich anbringbar ist, wobei zwischen dem Transformatorkern und dem Funktionsbereich ein Wärme leitendes Element angeordnet ist, sodass die vom der Transformatorkern erzeugbare Wärme zumindest teilweise zum Funktionsbereich übertragbar ist.The device according to the invention can be designed so that the transformer core can be attached directly to the functional area. However, the device according to the invention can also be designed such that the transformer core can be attached at a distance from the functional region, wherein a heat-conducting element is arranged between the transformer core and the functional region so that the heat which can be generated by the transformer core can be transferred at least partially to the functional region.

Der elektronische Schalter ist bevorzugt durch einen oder durch mehrere Transistoren gebildet. Die mehreren Transistoren sind bevorzugt parallel oder in Reihe geschaltet. Der elektronische Schalter kann aber auch durch andere elektronische Bauelemente wie z. B. durch einen Triac gebildet sein.The electronic switch is preferably formed by one or more transistors. The plurality of transistors are preferably connected in parallel or in series. The electronic switch can also be replaced by other electronic components such. B. be formed by a triac.

Der elektronische Schalter weist bevorzugt genau zwei Schaltzustände auf, nämlich einen offenen Schaltzustand und einen geschlossenen Schaltzustand. Im offenen Schaltzustand ist der elektronische Schalter hochohmig. Im geschlossenen Schaltzustand ist der elektronische Schalter nahezu kurzgeschlossen, d. h. niederohmig. Bei abgewandelten Ausführungsformen kann der elektronische Schalter auch weitere Schaltzustände aufweisen; beispielsweise mit einem mittleren Widerstandswert.The electronic switch preferably has exactly two switching states, namely an open switching state and a closed switching state. In the open switching state of the electronic switch is high impedance. In the closed switching state of the electronic switch is almost short-circuited, ie low impedance. In modified embodiments, the electronic switch can also further Have switching states; for example, with a mean resistance value.

Bei bevorzugten Ausführungsformen der erfindungsgemäßen Vorrichtung umfasst diese weiterhin eine Stromversorgungsschaltung, die eingangsseitig mit der Sekundärwicklung verbunden ist und die ausgangsseitig mit der Temperaturregelungselektronik verbunden ist. Die Stromversorgungsschaltung dient zur Wandlung der an der Sekundärwicklung anliegenden Wechselspannung in eine Versorgungsspannung für die Temperaturregelungselektronik. Diese Versorgungsspannung ist bevorzugt durch eine stabilisierte Gleichspannung gebildet; sie kann aber auch durch eine unstabilisierte Gleichspannung gebildet sein.In preferred embodiments of the device according to the invention, this further comprises a power supply circuit, which is connected on the input side to the secondary winding and the output side is connected to the temperature control electronics. The power supply circuit serves to convert the AC voltage applied to the secondary winding into a supply voltage for the temperature control electronics. This supply voltage is preferably formed by a stabilized DC voltage; but it can also be formed by an unstabilized DC voltage.

Die Stromversorgungsschaltung umfasst bevorzugt einen Elektroenergiespeicher. Der Elektroenergiespeicher dient zur Versorgung der Temperaturregelungselektronik in denjenigen zeitlichen Abschnitten, in denen die Sekundärwicklung durch den elektronischen Schalter kurzgeschlossen bzw. niederohmig geschaltet ist und daher keine elektrische Energie von der Sekundärwicklung abgegriffen werden kann.The power supply circuit preferably comprises an electric energy storage. The electric energy storage is used to supply the temperature control electronics in those time periods in which the secondary winding is short-circuited by the electronic switch or switched to low impedance and therefore no electrical energy can be tapped from the secondary winding.

Bei bevorzugten Ausführungsformen der erfindungsgemäßen Vorrichtung ist der Temperatursensor über eine Temperaturmesselektronik mit der Temperaturregelungselektronik verbunden. Die Temperaturmesselektronik dient zum Betrieb des Temperatursensors und/oder zur Verarbeitung des Messsignals des Temperatursensors.In preferred embodiments of the device according to the invention the temperature sensor is connected via a temperature measuring electronics with the temperature control electronics. The temperature measuring electronics serve to operate the temperature sensor and / or to process the measuring signal of the temperature sensor.

Bei einer zweiten Gruppe bevorzugter Ausführungsformen der erfindungsgemäßen Vorrichtung ist das Mittel zur Temperaturregelung durch einen heißleitenden Widerstand gebildet, welcher Wärme leitend mit dem Funktionsbereich verbunden ist. Erfindungsgemäß ist der Transformatorkern zum Erwärmen des Funktionsbereiches ausgebildet, wofür der Transformatorkern Wärme leitend mit dem Funktionsbereich verbunden ist. Der heißleitende Widerstand ist bevorzugt unmittelbar an die mindestens eine Sekundärwicklung angeschlossen. Der heißleitende Widerstand bestimmt die ohmsche Last der mindestens einen Sekundärwicklung. Bei einer Erhöhung der Temperatur des Funktionsbereiches verringert sich der elektrische Widerstand des heißleitenden Widerstandes, sodass die Spannung an der Sekundärwicklung sinkt und es zu einer verringerten Ummagnetisierung des Transformatorkernes kommt, wodurch die Ummagnetisierungsverluste sinken und der Transformatorkern weniger erwärmt wird.In a second group of preferred embodiments of the device according to the invention, the means for controlling the temperature is formed by a heat-conducting resistor, which is heat-conductively connected to the functional area. According to the invention, the transformer core is designed to heat the functional area, for which purpose the transformer core is heat-conductively connected to the functional area. The heat-conducting resistor is preferably connected directly to the at least one secondary winding. The heat conducting resistor determines the resistive load of the at least one secondary winding. As the temperature of the functional region increases, the electrical resistance of the thermally conductive resistor decreases, so that the voltage across the secondary winding decreases, and the transformer core is remagnetized, causing the core losses to decrease and the transformer core to be less heated.

Bei besonderen Ausführungsformen der erfindungsgemäßen Vorrichtung umfasst diese weiterhin ein elektrisches Kühlelement zum Kühlen des Funktionsbereiches, welches elektrisch mit der Temperaturregelungselektronik verbunden ist. Somit kann der Funktionsbereich je nach zu erzielender Temperatur mithilfe des Transformatorkernes bzw. des Heizelementes erwärmt werden oder mithilfe des Kühlelementes abgekühlt werden. Das elektrische Kühlelement kann unmittelbar mit der Temperaturregelungselektronik elektrisch verbunden sein. Das elektrische Kühlelement ist aber bevorzugt mittelbar über einen Leistungssteller mit der Temperaturregelungselektronik elektrisch verbunden. Die erfindungsgemäße Vorrichtung kann so ausgebildet sein, dass das elektrische Kühlelement unmittelbar am Funktionsbereich anbringbar ist. Die erfindungsgemäße Vorrichtung kann aber auch so ausgebildet sein, dass das elektrische Kühlelement beabstandet zum Funktionsbereich anbringbar ist, wobei zwischen dem elektrischen Kühlelement und dem Funktionsbereich ein Wärme leitendes Element angeordnet ist, sodass die vom elektrischen Kühlelement abführbare Wärme zumindest teilweise vom Funktionsbereich übertragbar ist.In particular embodiments of the device according to the invention, this further comprises an electric cooling element for cooling the functional area, which is electrically connected to the temperature control electronics. Thus, depending on the temperature to be achieved, the functional area can be heated by means of the transformer core or the heating element or by means of the cooling element be cooled. The electric cooling element may be electrically connected directly to the temperature control electronics. However, the electric cooling element is preferably indirectly electrically connected via a power controller with the temperature control electronics. The device according to the invention can be designed so that the electric cooling element can be attached directly to the functional area. However, the device according to the invention can also be embodied such that the electric cooling element can be attached at a distance from the functional region, a heat-conducting element being arranged between the electrical cooling element and the functional region, so that the heat which can be dissipated by the electrical cooling element can be transferred at least partially from the functional region.

Die Gasentladungslampe ist durch eine Quecksilberdampfniederdrucklampe gebildet und umfasst eine Glasröhre 01, in welcher sich Quecksilberdampf (nicht dargestellt) befindet. Die Glasröhre 01 ist an ihren beiden axialen Enden geschlossen. An einem der beiden axialen Enden der Glasröhre 01 ist eine erste Elektrode 02 angeordnet, während am anderen der beiden axialen Enden der Glasröhre 01 eine zweite Elektrode 03 angeordnet ist. Die beiden Elektroden 02, 03 befinden sich im Inneren der Glasröhre 01. Die erste Elektrode 02 ist über eine erste Anschlussleitung 04 und über eine zweite Anschlussleitung 06 angeschlossen. Auch die zweite Elektrode 03 ist über eine erste Anschlussleitung 07 und über eine zweite Anschlussleitung 08 angeschlossen. Die beiden Anschlussleitungen 04, 06 der ersten Elektrode 02 und die beiden Anschlussleitungen 07, 08 der zweiten Elektrode 03 sind an ein Vorschaltgerät 09 angeschlossen. Das Vorschaltgerät 09 stellt einen Entladungsstrom zum Betreiben der Gasentladungslampe bereit, der zur Gasentladung und somit zur Emission von UV-Strahlung führt. Weiterhin stellt das Vorschaltgerät 09 in einer Betriebsstartphase einen Heizstrom zum Beheizen der beiden Elektroden 02, 03 bereit. Die durch die vier Anschlussleitungen 04, 06, 07, 08 fließenden Ströme sind in der Darstellung als I1, I2, I3, I4 bezeichnet.The gas discharge lamp is formed by a low pressure mercury vapor lamp and comprises a glass tube 01 in which mercury vapor (not shown) is located. The glass tube 01 is closed at its two axial ends. At one of the two axial ends of the glass tube 01, a first electrode 02 is arranged, while at the other of the two axial ends of the glass tube 01, a second electrode 03 is arranged. The two electrodes 02, 03 are located inside the glass tube 01. The first electrode 02 is connected via a first connecting line 04 and via a second connecting line 06. The second electrode 03 is also connected via a first connecting line 07 and via a second connecting line 08. The two connection lines 04, 06 of the first electrode 02 and the two connecting lines 07, 08 of the second electrode 03 are connected to a ballast 09. The ballast 09 provides a discharge current for operating the gas discharge lamp, which leads to the gas discharge and thus to the emission of UV radiation. Furthermore, the ballast 09 provides a heating current for heating the two electrodes 02, 03 in an operating start phase. The currents flowing through the four connection lines 04, 06, 07, 08 are designated as I 1 , I 2 , I 3 , I 4 in the illustration.

Die beiden Anschlussleitungen 04, 06 der ersten Elektrode 02 sind durch einen Transformatorkern 11 hindurchgeführt, wo sie eine erste Primärwicklung 12 und eine zweite Primärwicklung 13 eines Transformators 14 bilden. Der Transformator 14 umfasst weiterhin eine Sekundärwicklung 16 auf dem Transformatorkern 11. Die beiden Primärwicklungen 12, 13 weisen einen gleichen Wicklungssinn auf.The two connection lines 04, 06 of the first electrode 02 are passed through a transformer core 11, where they form a first primary winding 12 and a second primary winding 13 of a transformer 14. The transformer 14 further comprises a secondary winding 16 on the transformer core 11. The two primary windings 12, 13 have the same winding sense.

Die Sekundärwicklung 16 speist eine Stromversorgungsschaltung 17, welche zur Wandlung der an der Sekundärwicklung 16 anliegenden Wechselspannung dient. Die Stromversorgungsschaltung 17 versorgt eine Temperaturmesselektronik 18, eine Temperaturregelungselektronik 19 und einen Leistungssteller 21 mit elektrischer Energie.The secondary winding 16 feeds a power supply circuit 17, which serves to convert the voltage applied to the secondary winding 16 AC voltage. The power supply circuit 17 supplies a temperature measuring electronics 18, a temperature control electronics 19 and a power controller 21 with electrical energy.

In der Glasröhre 01 der Gasentladungslampe ist ein Amalgamreservoir 22 ausgebildet, in welchem eine Amalgamkomposition (nicht dargestellt) angeordnet ist. Die Temperatur der Amalgamkomposition beeinflusst die Gasentladung in der Gasentladungslampe, sodass das Amalgamreservoir 22 einen die Funktion der Gasentladungslampe beeinflussenden Funktionsbereich der Gasentladungslampe darstellt.In the glass tube 01 of the gas discharge lamp, an amalgam reservoir 22 is formed, in which an amalgam composition (not shown) is arranged. The temperature of the amalgam composition influences the gas discharge in the gas discharge lamp, so that the amalgam reservoir 22 represents a functional region of the gas discharge lamp which influences the function of the gas discharge lamp.

Außerhalb der Glasröhre 01 sind am Amalgamreservoir 22 ein Temperatursensor 23 zum Messen der Temperatur des Amalgamreservoirs 22 und ein elektrisches Heizelement 24 zum Beheizen des Amalgamreservoirs 22 angeordnet.Outside the glass tube 01, a temperature sensor 23 for measuring the temperature of the amalgam reservoir 22 and an electric heating element 24 for heating the amalgam reservoir 22 are arranged on the amalgam reservoir 22.

Der Temperatursensor 23 ist elektrisch mit der Temperaturmesselektronik 18 verbunden, die ihrerseits elektrisch mit der Temperaturregelungselektronik 19 verbunden ist, sodass ein Temperaturmesssignal in der Temperaturregelungselektronik 19 verfügbar ist. Die Temperaturregelungselektronik 19 ist weiterhin elektrisch mit dem Leistungssteller 21 verbunden, über welchen das elektrische Heizelement 24 elektrische Energie erhält.The temperature sensor 23 is electrically connected to the temperature measuring electronics 18, which in turn is electrically connected to the temperature control electronics 19, so that a temperature measurement signal in the temperature control electronics 19 is available. The temperature control electronics 19 is further electrically connected to the power controller 21, via which the electric heating element 24 receives electrical energy.

Fig. 2 zeigt eine Prinzipdarstellung einer Ausführungsform der erfindungsgemäßen Gasentladungslampe. Fig. 2 shows a schematic diagram of an embodiment of the gas discharge lamp according to the invention.

Diese Ausführungsform gleicht zunächst dem in Fig. 1 gezeigten Beispiel. Im Unterschied zu Fig. 1 weist die Ausführungsform das elektrische Heizelement 24 und den Leistungssteller 21 nicht auf. Stattdessen ist die Temperaturregelungselektronik 19 elektrisch mit einem elektronischen Schalter 26 verbunden, über welchen die Sekundärwicklung 16 kurzgeschlossen werden kann. Der erfindungsgemäße Unterschied zu Fig. 1 besteht weiter darin, dass der Transformatorkern 11 über eine thermische Kopplung 27 Wärme leitend mit dem Amalgamreservoir 22 verbunden ist, sodass vom Transformatorkern 11 erzeugte Wärme teilweise auf das Amalgamreservoir 22 übertragen wird.This embodiment is initially similar to the one in FIG Fig. 1 shown example. In contrast to Fig. 1 For example, the embodiment does not include the electric heater 24 and the power controller 21. Instead, the temperature control electronics 19 is electrically connected to an electronic switch 26, via which the secondary winding 16 can be short-circuited. The difference according to the invention Fig. 1 It further consists in that the transformer core 11 is conductively connected to the amalgam reservoir 22 via a thermal coupling 27 so that heat generated by the transformer core 11 is partially transferred to the amalgam reservoir 22.
