Description

Beleuchtungsanlage mit Gasentladungslampen Bei der bekannten Art der Helligkeitssteuerung von Gasentladungslampen, wie z. B. Neonröhren, durch feinstufig steuerbare Transformatoren, liegt der Zündeinsatz in einem Gebiet, in dem bereits gezündete Lampen eine verhältnismäßig große Helligkeit haben. Dadurch wird der Bereich der Helligkeitssteuerung begrenzt. Außerdem fallen bei mehreren, beispielsweise zu einem Lüster vereinigten Röhren die unvermeidbar verschieden hoch liegenden Zündeinsätze in größerer Helligkeit der Lampen störend auf.Lighting system with gas discharge lamps In the known type of Brightness control of gas discharge lamps, such as B. neon tubes, by finely graduated controllable transformers, the ignition point is in an area where already ignited lamps have a relatively high brightness. This will make the area the brightness control is limited. Also fall in the case of several, for example The tubes, which inevitably had different heights, united the tubes in a chandelier annoying in the greater brightness of the lamps.

Gegenstand der Erfindung ist eine Beleuchtungsanlage mit Gasentladungslampen, bei der die Netzfrequenz des zugeführten Wechselstromes verändert werden kann.The invention relates to a lighting system with gas discharge lamps, at which the mains frequency of the supplied alternating current can be changed.

Es sind Beleuchtungsanlagen mit Gasentladungslampen bekannt, bei denen die Netzfrequenz des zugeführten Wechselstromes verändert ist. Man hat nämlich die Lampen mit gleichbleibender erhöhter Frequenz betrieben. Die Frequenzerhöhung in diesen Anlagen hat den Zweck, die Vorschaltgeräte in ihren Abmessungen zu verkleinern und die Lichtausbeute der Lampen etwas zu steigern. Bei der Beleuchtungsanlage nach der Erfindung wird eine veränderbare Frequenz für eine wesentliche Verbesserung der Helligkeitssteuerung ausgenutzt. Diese Verbesserung wird dadurch erzielt, daß die Frequenz während des Zündens zur Verlegung des Zündpunktes in das Gebiet kleinerer Helligkeit erhöht wird. Dies kann beispielsweise mit Hilfe eines Frequenzwandlers geschehen.There are known lighting systems with gas discharge lamps in which the mains frequency of the supplied alternating current has changed. You have that Lamps operated with a constant increased frequency. The frequency increase in The purpose of these systems is to reduce the size of the ballasts and to slightly increase the light output of the lamps. At the lighting system after the invention provides a variable frequency for a substantial improvement the brightness control exploited. This improvement is achieved in that the frequency during ignition to relocate the ignition point to the smaller area Brightness is increased. This can be done, for example, with the help of a frequency converter happen.

Da die Ionisation eines Gases mit steigender Frequenz bereits bei kleinen Spannungen einsetzt, kann auf diese Weise der Zündbeginn von Gasentladungslampen in das Gebiet kleinerer Helligkeit verlegt werden. Dabei ergibt sich beispielsweise bei einer Frequenzerhöhung von 50 auf 500 Hz ein Zündeinsatz, welcher bei einer um rund das Siebenfache kleineren Helligkeit liegt. Die Frequenzerhöhung und die auf diese Weise erreichte Vorverlegung des Zündbeginnes hat vor allein auch den Vorteil, daß der Helligkeitssteuerbereich der Anlage wesentlich erhöht wird. Bis zu einer Frequenz von 500 Hz lassen sich noch die handelsüblichen für 50 Hz ausgelegten Transformatoren verwenden, so daß bei Verwendung dieser im Notfall sofort auf das normale Stromversorgungsnetz umgeschaltet werden kann. An Stelle der bei 50 Hz als Steuergerät üblichen Steuertransformatoren mit Seilzügen kann man beim Erfindungsgegenstand einen Motorgenerator als Frequenzwandler vorsehen, wobei die Spannungsänderung einfach durch Steuern der Erregung erfolgt.Since the ionization of a gas with increasing frequency already occurs at If small voltages are used, gas discharge lamps can start to ignite in this way be relocated to the area of lower brightness. This results for example with a frequency increase from 50 to 500 Hz an ignition insert, which with a around seven times lower brightness. The frequency increase and the advancement of the start of ignition achieved in this way also has before alone Advantage that the brightness control range of the system is significantly increased. To up to a frequency of 500 Hz, the standard ones designed for 50 Hz can be used Use transformers so that if you use them in an emergency you can immediately access the normal power supply network can be switched. Instead of the one at 50 Hz as Control unit conventional control transformers with cables can be found in the subject matter of the invention Provide a motor generator as a frequency converter, the voltage change being easy is done by controlling the excitation.
