Description

Die Erfindung betrifft eine Schaltung für den Blinkbetrieb von Signallampen. Die Erfindung besteht darin; daß die Signallampen in Reihe mit der Sekundärwicklung eines Transformators dauernd an die Speisespannung angeschaltet sind und daß die Primärwicklung des Transformators über den $linkschalter an eine Speisespannung anschaltbar ist, so däß bei Betätigung des Schalters eine Änderung der Spannung an den Signallampen eintritt.The invention relates to a circuit for the flashing operation of signal lamps. The invention consists in; that the signal lamps in series with the secondary winding of a transformer are permanently connected to the supply voltage and that the Primary winding of the transformer to a supply voltage via the left switch can be switched on, so that when the switch is operated, the voltage changes enters at the signal lamps.

Die Erfindung wird an Hand der Figur näher beschrieben. Die Signallampen 7, welche zweckmäßig parallel liegen, sind in Reihe mit der Transforrnatorwicklung 2 an die Transformatorwicklung i angeschlossen. Über die Wicklung i wird die Speisespannung zugeführt. Die Primärwicklung 6 dieses Transformators liegt dauernd an der Netzspannung. - Die Primärwicklung 5 der Transformatorwicklung 2 ist mittels des Blinkschalters 3 an das Netz anschaltbar Durch Betätigung des Schalters 3 wird die Spannung an den Signallampen geändert. Je nach Polung wird die Spannung an der Spule z zu der Spannung an der Spule addiert oder subtrahiert. Vorteilhaft ist es, wenn die Spannung an 2 der Spannung an i gegengeschaltet ist. Die Spannung an der Wicklung :2 wird: zweckmäßig so gewählt, däß, die Lampenspannung auf 1/.. reduziert wird. Um dabei stabile Spannungen an den Signallampen i zu erhalten, also den Einfuß der Lampenzahl klein zu halten, ist es zweckmäßig, den Transformator 5-2 zu belasten, z. B., durch einen Widerstand q, parallel zur Wicklung 5.The invention is described in more detail with reference to the figure. The signal lamps 7, which are expediently parallel, are in series with the transformer winding 2 connected to the transformer winding i. The supply voltage is applied via winding i fed. The primary winding 6 of this transformer is permanently connected to the mains voltage. - The primary winding 5 of the transformer winding 2 is by means of the flasher switch 3 can be connected to the mains By pressing switch 3, the voltage is applied changed the signal lamps. Depending on the polarity, the voltage on the coil z becomes the Voltage on the coil added or subtracted. It is advantageous if the tension at 2 the voltage at i is connected in the opposite direction. The voltage on the winding: 2 becomes: expediently chosen so that the lamp voltage is reduced to 1 / ... To do it to maintain stable voltages at the signal lamps i, i.e. the influence of the number of lamps To keep small, it is useful to load the transformer 5-2, z. B., through a resistor q, parallel to winding 5.

_ Die_Erzeugung_von Blinklicht, ohne: den Lampenstromkreis ganz zu unterbrechen, allein durch Senkung der Brennspannung, schont in hohem Maße die Glühfäden der Lampen und erhöht ihre Lebensdauer. Es genügt, wenn die mit voller Spannung weißglühenden Lampen nur auf Rotglut abgekühlt werden, was bei etwa 1/s der Normalspannung der Fall ist._ The_production_ of flashing lights without: completely closing the lamp circuit interrupting, simply by lowering the operating voltage, protects the filaments to a great extent of the lamps and increases their service life. It is enough if the full tension Incandescent lamps can only be cooled down to red heat, which is around 1 / s of normal voltage the case is.

Die Erfindung findet Anwendung bei Leuchtschaltbildern, ferner bei Blinklichtsignalen aller Art.The invention is used in luminous circuit diagrams, and also in Flashing light signals of all kinds.
