Description

Bekanntlich ergeben sich sehr große Schwierigkeiten, das Licht starker Lichtquellen hinreichend stark und hinreichend schnell zu modulieren, sei es, däß dazu gesteuerte Blenden verwendet werden oder daß der elektrische Speisestrom selbst moduliert würde.It is well known that there are very great difficulties, the light is stronger To modulate light sources sufficiently strong and sufficiently fast, be it that controlled diaphragms are used for this purpose or that the electrical feed current itself would be modulated.

Erfindungsgemäß wird der Lichtbogen einer Metalldampflampe, insbesondere einer Quecksilberhochdrucklampe, mittels eines Elektromagneten in der Weise moduliert, dag der Lichtbogen im Magnetfeld gegenüber einer Blenden-, Linsen- oder Spiegelanordnung abgelenkt wird. Eine derartige Anordnung kann für alle Zwecke, bei denen eine schnelle Lageveränderung der eigentlichen Leuchtfläche gegenüber z. B! einer Optik erforderlich ist, für lichtelektrische Steuerungen an Stelle einer Lochscheibenanordnung, für Bildtelegrafie- und Fernsehzwecke oder auch für fotografische Tonaufnahme und Wiedergabe mit Erfolg verwendet werden.According to the invention, the arc of a metal halide lamp, in particular a high-pressure mercury lamp, modulated by means of an electromagnet in the way, dag the arc in the magnetic field compared to a diaphragm, lens or mirror arrangement is distracted. Such an arrangement can be used for all purposes where rapid Change of position of the actual luminous area compared to z. B! optics required is, for photoelectric controls instead of a perforated disk arrangement, for Image telegraphy and television purposes or also for photographic sound recording and reproduction can be used with success.

In der Zeichnung ist der Gegenstand der Erfindung an Ausführungsbeispielen dargestellt.In the drawing, the subject matter of the invention is based on exemplary embodiments shown.

In, den Fig. i und 2 ist i die Gasentladungsstrecke, deren Lichtbogen durch das veränderliche magnetische Feld des Magneten, hier eines Elektromagneten 3, seitlich entsprechend den. Stromänderungen abgelenkt wird, q. ist ein Blendenschirm, mit einer Öffnung q@'. Hinter der Öffnung kann z. B. eine Fotozelle ä angeordnet sein, auf die bei der seitlichen Ablenkung des Lichtbogens veränderliche Lichtströme fallen.In FIGS. I and 2, i is the gas discharge path and its arc by the variable magnetic field of the magnet, here an electromagnet 3, laterally corresponding to the. Current changes is deflected, q. is a visor, with an opening q @ '. Behind the opening can, for. B. arranged a photocell ä be on the variable luminous fluxes when the arc is deflected to the side fall.

In der Fig. 3 ist eine schematische Anordnung mit einer optischen Einrichtung dargestellt, die bei den bekannten. Gegentaktfotometern bzw. Steuereinrichtungen dazu dienen kann, das Licht abwechselnd durch Lichtleiter 6 und, 7, zur Fotozelle S gelangen zu lassen, sobald eine gleichgehaltene Wechselspannung, die die, eines Wechselstromnetzes sein kann, den Elektromagneten erregt.In Fig. 3 is a schematic arrangement with an optical Establishment shown in the well-known. Push-pull photometers or control devices can serve to alternate the light through light guides 6 and 7, to the photocell S to get as soon as a constant alternating voltage, which the, one AC network can be energized the electromagnet.
