Description
Technisches GebietTechnical area
Die Erfindung geht aus von einer Hochdruckentladungslampe gemäß dem Oberbegriff des Anspruchs 1. Derartige Lampen sind insbesondere Hochdruckentladungslampen für Allgemeinbeleuchtung oder für fotooptische Zwecke.The The invention is based on a high pressure discharge lamp according to the The preamble of claim 1. Such lamps are in particular high-pressure discharge lamps for general lighting or for photo-optical Purposes.
Stand der TechnikState of the art
Bei der Resonanzzündung von Hochdruckentladungslampen wird in einem gering bedämpften L-C-Schwingkreis eine resonante Spannungsüberhöhung angeregt. Die Induktivität L befindet sich dabei im EVG, die Kapazität C befindet sich auch zum Teil im EVG und wird ansonsten durch die Leitungskapazität zur Lampe gebildet. Die Lampe steuert nur einen sehr kleinen Teil zur Kapazität bei. Wird die Lampe beispielsweise zum Wechseln entfernt, so liegt die Zündspannung an der Lampenfassung an und stellt für den Benutzer eine Gefahr dar. Dies gilt vor allem bei heißzündfähigen Lampen.at the resonance ignition of high pressure discharge lamps is in a low-attenuation L-C resonant circuit a resonant Voltage increase excited. The inductance L is located in the ECG, the capacity C is located also partially in the TOE and will otherwise by the line capacity formed to the lamp. The lamp controls only a very small part to capacity. If the lamp, for example, to change removed, the ignition voltage is at the lamp socket and represents a danger to the user. This applies especially with heat-ignitable lamps.
Bislang wird bei heißzündfähigen Systemen durch zusätzliche Schutzschalter verhindert, dass bei geöffneter Leuchte, wenn die Lampe entfernt ist, trotzdem noch Hochspannung erzeugt werden kann. Diese Maßnahme erfordert jedoch zusätzlichen mechanischen und schaltungstechnischen Aufwand.So far is used in hot-ignition systems additional circuit breaker prevents when open Light, when the lamp is removed, still high voltage can be generated. However, this measure requires additional mechanical and circuit complexity.
Darstellung der ErfindungPresentation of the invention
Die Aufgabe der vorliegenden Erfindung ist es, eine Hochdruckentladungslampe bereitzustellen, deren Zündverhalten gegenüber bisherigen Lampen deutlich sicherer ist.The The object of the present invention is a high-pressure discharge lamp to provide their ignition behavior over previous lamps is much safer.
Dies gilt insbesondere für Metallhalogenidlampen, wobei das Material des Entladungsgefäßes entweder Quarzglas oder Keramik sein kann.This applies in particular to metal halide lamps, the Material of the discharge vessel either quartz glass or ceramic can be.

Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen.Especially advantageous embodiments can be found in the dependent Claims.
Erfindungsgemäß wird jetzt die Kapazität des Resonanzkreises durch einen im Außenkolben oder auch Sockel der Lampe befindlichen Kondensator realisiert. das Entfernen der Lampe bedeutet automatisch auch ein Entfernen dieses Kondensators. So kommt es beim Entfernen der Lampe zu einer deutlichen Verstimmung des Resonanzkreises. Vorausgesetz ist dass die Kapazität des Sicherheitskondensators ausreichend hoch gewählt ist. Insbesondere sollte sie mindestens 10% der Gesamtkapazität betragen.According to the invention now the capacity of the resonant circuit by a in Outer bulb or socket of the lamp located capacitor realized. the removal of the lamp automatically means also one Remove this capacitor. This is how the lamp is removed to a significant detuning of the resonant circuit. advance Act is that the capacity of the safety capacitor is sufficient is high. In particular, it should be at least 10% the total capacity.
Die Verstimmung des rudimentären Resonanzkreises hat zur Folge, dass eine gefährdende Resonanzüberhöhung vermieden wird.The Detuning of the rudimentary resonant circuit results in that a dangerous resonance cant is avoided.
Alternativ oder zusätzlich kann die Verstimmung des Resonanzkreises durch das EVG detektiert werden, so daß dann die Zündversuche unterbunden werden.alternative or additionally, the detuning of the resonant circuit be detected by the ECG, so that then the ignition attempts be prevented.
Als
Kondensator wird ein temperaturfester, keramischer Typ, vorzugsweise
in LTCC-Technologie, verwendet. Eine derartige Technologie ist beispielsweise
in
Das vorgeschlagene Konzept zeichnet sich durch inhärente Sicherheit aus, da eine Fehlbedienung, d. h. ein Einschalten ohne Lampe, automatisch verhindert ist. Außerdem kann vorteilhaft die Größe der Kapazität des Kondensators zur Kennzeichnung der Leistung der eingesetzten Lampe mittels automatischer Erkennung durch das EVG genutzt werden.The proposed concept is characterized by inherent security because a misoperation, d. H. switching on without lamp, automatically prevented is. In addition, the size of the advantageous Capacitance of the capacitor to indicate the power the lamp used by automatic detection by the ECG be used.
