Die Erfindung betrifft eine Schaltvorrichtung für elektrische Glühlampen zur Erzeugung einer intermittierenden Beleuchtung, bei der das periodische Unterbrechen, und Schließen des Lampenstromkreises durch einen als Selbstunterbrecher arbeitenden, theranostatischen Schalter bewirkt wird.The invention relates to a switching device for electric incandescent lamps for generation an intermittent lighting in which the periodic interruption, and closing of the lamp circuit through a self-interrupter, theranostatic Switch is effected.

Die Erfindung besteht darin, daß der bewegliche Teil des genannten Schalters aus einemThe invention consists in that the moving part of said switch consists of a

ίο Bimetall besteht, das mit einer in Reihe mit dem elektrischen Strom geschalteten Heizwicklung versehen ist, und daß der ganze Stromschalter in einem evakuierten oder mit indifferentem Gas gefüllten Behälter angebracht ist.ίο consists of bimetal that is in series with the electric current switched heating coil is provided, and that the whole Power switch mounted in an evacuated or inert gas-filled container is.

Infolge seiner Bauart ist dieser Stramschalter für die Anwendung bei BMnklichtlampen sehr geeignet, wobei der Lampenstrom eine derartige Stärke besitzt, daß periodisches Unterbrechen und Schließen desselben bewirkt ao wird. Weil dieser Stromschalter wenigstens ebensolange wie der Glühdraht der Glühlampe dauert und somit kein Austausch oder Ausbesserung bei einer derartigen Blinklichtlampe erforderlich ist, sieht man die praktische Verwendbarkeit des Stromschalters für den angegebenen Zweck in einer Blinklichtlampe leicht ein. Er kann entweder innerhalb der Lampe oder an jedem geeigneten Platz in der Stromleitung angebracht werden. Im ersteren FallDue to its design, this on / off switch is suitable for use with BMnklichtlampen very suitable, the lamp current having such a strength that periodic Interrupting and closing the same is effected ao. Because this power switch at least As long as the filament of the light bulb lasts and therefore no replacement or repair is required in such a flashing lamp, one can see the practical usability of the power switch for the stated purpose in a flashing light bulb easily a. It can either be inside the lamp or in any convenient place on the power line be attached. In the former case

kann der Stromunterbrecher innerhalb der Birne selbst oder im Sockel der Lampe angebracht werden. Sitzt der Schalter in der Birne, so ist er vorzugsweise in einem rohrförmigen Behälter zentral in der Lampe untergebracht. the circuit breaker can be placed inside the bulb itself or in the base of the lamp will. If the switch is in the bulb, it is preferably in a tubular shape Container housed centrally in the lamp.

Ein derartiger Stromschalter kann auch infolge seiner kleinen Abmessung beispielsweise in Lampenhaltern angebracht werden.Such a power switch can also, for example, due to its small size be attached in lamp holders.

ίο Die Erfindung wird in der Zeichnung veranschaulicht, die als Ausführungsbeispiel eine Glühlampe darstellt, welche periodisch gezündet und ausgelöscht wird, d. h. eine Blinklichtlampe. ίο The invention is illustrated in the drawing, which represents an incandescent lamp as an exemplary embodiment, which is ignited periodically and is extinguished, d. H. a flashing lamp.

In dem gezeigten Beispiel ist der Thermostat innen in der Lampe 1 angebracht, welche aus einer gewöhnlichen Glühlampe mit evakuierter oder gasgefüllter Birne bestehen kann. Der Thermostat besteht aus zwei in demIn the example shown, the thermostat is mounted inside the lamp 1, which can consist of an ordinary incandescent lamp with an evacuated or gas-filled bulb. The thermostat consists of two in the

ao Glasfuß 2 oder im Behälter 8 eingeschmolzenen federnden Kontaktzungen 3, 4, von welchen eine aus Bimetall besteht. Diese Kontaktzungen 3, 4 sind mit Kontakten S, 6 versehen, welche miteinander normal in Kontakt sind und zweckmäßig aus Wolfram, Molybdän, Tantal oder ähnlichem, schwer schmelzendemao glass base 2 or resilient contact tongues 3, 4 melted in the container 8, one of which is made of bimetal. These contact tongues 3, 4 are provided with contacts S, 6 which are normally in contact with one another and are expediently made of tungsten, molybdenum, tantalum or the like, which have a low melting point

__ Metall bestehen, um die Lichtbogenbildung beim Unterbrechen des Stromes zu vermindern.__ Made of metal to prevent arcing to reduce when the current is interrupted.

Der Thermostat 3, 4 ist mit dem Glühdraht 7 in Reihe eingeschaltet. Wenn der Thermostat unter der Einwirkung der Heizwicklung steht, wird derselbe beim Schließen des Stromes durch die Lampe in Tätigkeit gebracht, so daß der Strom nach einer kurzen; Weile an dem Kontakte 5, 6 unterbrochen wird. Wenn der Thermostat infolgedessen kalt wird, wird der Strom aufs neue geschlossen, wobei die Heizwicklung Wärme erzeugt, so daß der Thermostat wieder beeinflußt wird. In dieser Weise wird ein blinkendes Licht ohne irgendwelche äußeren Relaisvorrichtungen erhalten. Dabei ist zu bemerken, daß praktisch keine zusätzliche Energie zwecks Betätigung des Thermostates verbraucht wird, da dieser keinen nennenswerten Widerstand hat, sondern es wird der Thermostat nur durch die von der Heizwicklung ausstrahlende Energie beeinflußt. Die Empfindlichkeit des Thermostates 3, 4 ist zufolge der Heizwicklung sehr groß; daher kann die Zeitlänge der Stromunterbrechungen genau geregelt werden.The thermostat 3, 4 is switched on in series with the glow wire 7. If the Thermostat is under the action of the heating coil, becomes the same when closing of the current brought into action by the lamp, so that the current after a short; While contacts 5, 6 are interrupted. If the thermostat becomes cold as a result, the electricity will be closed again, whereby the heating coil generates heat, so that the thermostat is influenced again. In this way it becomes a blinking light without any outside relay devices. It should be noted that practically no additional energy is used to operate the thermostat, since this has no significant resistance, it just becomes the thermostat influenced by the energy radiating from the heating coil. The sensitivity the thermostat 3, 4 is very large due to the heating coil; therefore the length of time the power interruptions are precisely regulated.
