Description

Einrichtung zur Regelung von elektrischen Wechselstrombühnenbeleuchtungsanlagen Gegenstand des Hauptpatents 656 io6 ist eine Einrichtung zur Regelung von elektrischen Wechselstrombühnenbeleuchtungsanlagen mit Hilfe von gittergesteuerten Gas- oder Dampfentladungsstrecken in Antiparallelschaltung. Das kennzeichnende Merkmal dieser Regeleinrichtung besteht darin, daß zwischen die Beleuchtungsanlage und die Entladungsstrecken eine mit diesen in Reihe geschaltete Drosselspule geschaltet ist. Es wird dadurch erreicht, daß nur Regelapparate mit. verhältnismäßig kleinen Abmessungen für die Bühnenbeleuchtungsanlage notwendig sind, was insbesondere bei größeren Theaterbeleuchtungsanlagen von wesentlicher Bedeutung ist. Ein weiterer Vorteil besteht darin, daß zwischen die Regeleinrichtung und die daran angeschlossenen Beleuchtungskörper noch Spannungstransformatoren geschaltet werden können., durch die die Spannung, welche dem Beleuchtungskörper zugeführt wird, den blesonderen Anforderungen, wie sie durch Fadenabmessungen o. dgl. gegeben sind, angopal.)t werden können.Device for regulating electrical alternating current stage lighting systems The subject of the main patent 656 io6 is a device for the regulation of electrical AC stage lighting systems with the help of grid-controlled gas or Vapor discharge paths in anti-parallel connection. The distinguishing feature of this Control device consists in that between the lighting system and the discharge paths a choke coil connected in series with these is connected. It becomes through it achieved that only control apparatus with. relatively small dimensions for the Stage lighting systems are necessary, which is particularly important for larger theater lighting systems is essential. Another advantage is that between the control device and the lighting fixtures connected to it or voltage transformers can be switched. by which the voltage applied to the lighting fixture is supplied to the bles special requirements, as they are due to thread dimensions o. Like. Are given, angopal.) t can be.

Die Erfindung betrifft eine Verbesserung und weitere Ausgestaltung dieser Regeleinrichtung. Gemäß der Erfindung wird die die Beleuchtungsanlagen steuernde Regeleinrichtung derart ausgebildet, daß die gesteuerten Gas- oder Dampfentladungsstrecken, welche in dem Beleuchtungsstromkreis liegen, mit voller Aussteuerung arbeiten, wenn, den Beleuchtungskörpern eine ihrer vollen Lichtstärke .entsprechende Spannung zugeführt wird.The invention relates to an improvement and further development this control device. According to the invention, the one controlling the lighting systems Control device designed in such a way that the controlled gas or vapor discharge paths, which are in the lighting circuit, work with full modulation if, The lighting fixtures are supplied with a voltage corresponding to their full light intensity will.

Die Erfindung beruht auf der Erkenntnis, daß man Beleuchtungskörper zwar in weiten Grenzen mit Hilfe von steuerbaren Gas- oder Dampfentladungsstrecken in ihrer Beleuchtungsstärke regeln kann, daß jedoch zwischen der Beleuchtungsstärke und dem Aussbeuerungsgrad der Gasentladungsstrecken gewisse Beziehungen bestehen, deren Berücksichtigung eine wesentliche Verbesserung des Beleuchtungseffektes bedeutet. Dui'Ch Versuche wurde festgestellt, daß eine Glühlampe bei Betrieb mit einer Spannungskurve von der verzerrten Form, wie sie bei Teilaussteuerung von Gasentladungsgefäßen vorhanden ist, bei hoher Temperatur des Glühfadens, also bei voller Beleuchtungsstärke, flimmert, während sie bei derselben Form der Spannungskurve bei niedriger Temperatur dies Glühfadens nicht flimmert. Eine Glühlampe ist also bei hoher Glühfadentemperatur wesentlich flimmerempfindlicher als bei niedriger Glühfadentemperatur. Wenn die Regeleinrichtung für die Beleuchtungsanlage gemäß der Erfindung derart ausgebildet ist, daß bei voller B,eleuc@-, tungsstärke mit voller Aussteuerung oder z mindest mit annähernd voller Aussteueru g.. der Entladungsgefäße gearbeitet und den Glühfäden eine möglichst unverzerrte Spannung zugeführt wird, so ist flimmerfreier Betrieb im ganzen Bereich der Beleuchtungsstärke der Glühlampen zwischen o und ioo@rio gewährleistet.The invention is based on the knowledge that one lighting fixture within wide limits with the help of controllable gas or vapor discharge paths can regulate their illuminance, but that between the illuminance and the degree of diffusion of the gas discharge paths, there are certain relationships, the consideration of which means a significant improvement in the lighting effect. Dui'Ch experiments it was found that an incandescent lamp when operated with a voltage curve from the distorted shape, as it exists with partial modulation of gas discharge vessels is, at a high temperature of the filament, i.e. at full illuminance, flickers, while at the same shape of the voltage curve at low temperature they do Filament does not flicker. So an incandescent lamp is at high Filament temperature much more sensitive to flicker than when the filament temperature is low. If the Control device for the lighting system according to the invention designed in this way is that at full B, eleuc @ -, power with full modulation or at least z Worked with almost full modulation of the discharge vessels and the filaments If a voltage is supplied that is as undistorted as possible, operation is flicker-free guaranteed in the entire range of illuminance of the incandescent lamps between o and ioo @ rio.

Obwohl die Erfindung von wesentlicher Bedeutung für solche Bühnenbeleuchtungsanlagen ist, die gemäß dem Hauptpatent über antiparallel geschaltete Entladungsstrecken und eine Seriendrosselspule an eine Wechselstromquelle angeschlossen sind, kann sie auch für andere Beleuchtungsanlagen mit Vorteil verwendet werden, bei denen die Beleuchtungskörper über steuerbare Gas- oder Dampfentladungsstrecken aus einer Wechselstromquelle mit einem Strom versorgt werden, der aus Stromimpulsen steuerbarer Zeitdauer besteht, wobei diese Impulse entweder wechselnde -oder gleiche Richtung haben können.Although the invention is essential for such stage lighting systems is that according to the main patent via antiparallel-connected discharge paths and a series reactor connected to an AC power source they can also be used to advantage for other lighting systems where the lighting fixtures via controllable gas or vapor discharge paths from a AC power source can be supplied with a current that is controllable from current pulses Duration exists, with these pulses either alternating or in the same direction can have.
