Description

Die Erfindung betrifft einen Druckknopfschalter mit lichtemittierenden Halbleitern als Lichtquelle für Aufzüge, wobei das Licht der auf einer gedruckten Schaltung angeordneten lichtemittierenden Halbleiter als Quittungsmeldung auf einen lichtdurchlässigen Druckknopf gelenkt wird.The invention relates to a push button switch with light-emitting semiconductors as a light source for elevators, the light of the light-emitting semiconductors arranged on a printed circuit being directed as a confirmation message onto a translucent push button.

Aus dem DE Gebrauchsmuster G 90 15 115.1 ist ein Leuchtelement mit lichtemittierenden Halbleitern für Drucktastenschalter bekannt. Im Kopfteil des Drucktastenschalters ist ein mit einer Leiterplatte in Verbindung stehender ringförmiger Lichtleiter angeordnet, der das Licht von den auf der Leiterplatte integrierten lichtemittierenden Halbleitern an die Frontseite der Drucktaste leitet, wobei bedienerseitig ein Lichtring als Quittungsmeldung sichtbar wird. Die lichtemittierenden Halbleiter, auch Leuchtdioden genannt, werden abhängig vom Umfeldlicht mittels Fotohalbleitern geregelt, so dass der sichtbare Lichtring umso heller leuchtet, je heller das Umfeldlicht ist.A light-emitting element with light-emitting semiconductors for push-button switches is known from DE utility model G 90 15 115.1. In the head part of the push button switch there is an annular light guide connected to a printed circuit board, which guides the light from the light-emitting semiconductors integrated on the printed circuit board to the front of the push button, a light ring being visible on the operator side as a confirmation message. The light-emitting semiconductors, also called light-emitting diodes, are regulated by means of photo semiconductors depending on the ambient light, so that the brighter the ambient light, the brighter the visible light ring.

Ein Nachteil der bekannten Einrichtung liegt darin, dass das von den Leuchtdioden ausgesendete Licht bei Stockwerken einer Aufzugsanlage mit grosser Beleuchtungsstärke auf der Drucktaste nur ungenügend sichtbar ist. Ein weiterer Nachteil besteht in der aufwendigen Herstellung der in Verbindung mit dem Lichtleiter stehenden Leiterplatte.A disadvantage of the known device is that the light emitted by the light-emitting diodes on floors of an elevator system with high illuminance is only insufficiently visible on the push button. Another disadvantage is the complex manufacture of the circuit board connected to the light guide.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtung zu vermeiden und einen Druckknopfschalter zu schaffen, bei dem die von Leuchtdioden erzeugte Quittungsmeldung mit Glühlampenbeleuchtungsstärke auf dem Druckknopf erscheint.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and of creating a push button switch in which the acknowledgment message generated by light-emitting diodes appears with the light bulb illuminance on the push button.

Der durch die Erfindung erreichte Vorteil ist im wesentlichen darin zu sehen, dass in bestehenden Einrichtungen glühbirnenbetriebene Druckknopfschalter mit Leuchtdioden aufgerüstet werden können ohne dass dabei die ästhetische Aufmachung durch unterschiedliche Beleuchtungsstärken beeinträchtigt wird.The advantage achieved by the invention is essentially to be seen in the fact that in existing facilities, lightbulb-operated pushbutton switches can be equipped with light-emitting diodes without the aesthetic appearance being impaired by different illuminance levels.

In den Fig. 1 bis 5 ist mit 1 eine Deckplatte mit einer nicht dargestellten Öffnung bezeichnet, durch die ein Abschlussring 2 tritt in den rückseitig ein mit einer Linsenkappe 3 versehener Druckknopf 4 eintaucht. Stössel 5 des Druckknopfes 4 durchdringen einen bestehenden Adapter 6 und betätigen einen nicht dargestellten von einem Schalterblock 7 getragenen Schalter. Ein aus einem Fuss 8 und einem Reflektorteil 9 bestehender Lichtreflektor 10 ist in eine Öffnung 11 des Adapters 6 eingesetzt, wobei der Lichtreflektor 10 an einer äusseren Schulter 12 an dem Adapter 6 aufliegt. Eine gedruckte Schaltung 13 mit Leuchtdioden LED1 ... LED5 und Dioden D1 ... D4 taucht rückseitig soweit in den Fuss 8 des Lichtreflektors 10 ein, bis diese an einer inneren Schulter 14 aufliegt. Die Versorgungsspannung der Diodenschaltung wird der gedruckten Schaltung 13 mittels Anschlussdrähten L1;L2 zugeführt. Die auf der gedruckten Schaltung 13 angeordneten Leuchtdioden LED1 ... LED5 durchdringen den Lichtreflektor 10 in Bohrungen B1 ...B5 und ragen in den mit einer Schräge 15 versehenen Reflektorteil 9 hinein. Die zentral angeordnete Bohrung B5 wird von einer angeschrägten Überhöhung 16 umgeben.1 to 5, 1 designates a cover plate with an opening, not shown, through which a closing ring 2 enters, into which a push button 4 provided with a lens cap 3 is inserted on the rear. Plunger 5 of the push button 4 penetrate an existing adapter 6 and actuate a switch (not shown) carried by a switch block 7. A light reflector 10 consisting of a base 8 and a reflector part 9 is inserted into an opening 11 of the adapter 6, the light reflector 10 resting on an outer shoulder 12 on the adapter 6. A printed circuit 13 with light-emitting diodes LED1 ... LED5 and diodes D1 ... D4 plunges into the base 8 of the light reflector 10 until it rests on an inner shoulder 14. The supply voltage of the diode circuit is supplied to the printed circuit 13 by means of connecting wires L1; L2. The light-emitting diodes LED1 ... LED5 arranged on the printed circuit 13 penetrate the light reflector 10 in bores B1 ... B5 and protrude into the reflector part 9 provided with a bevel 15. The centrally arranged bore B5 is surrounded by a beveled elevation 16.

Adapter 6 und Schalterblock 7 werden von an der Deckplatte 1 angeordneten Trägerbolzen 17 und Muttern 18 gehalten. Je nach Adapter 6 werden zylindrische, kubische oder andersartig geformte Lichtreflektoren 10 verwendet.Adapter 6 and switch block 7 are held by carrier bolts 17 and nuts 18 arranged on the cover plate 1. Depending on the adapter 6, cylindrical, cubic or other shaped light reflectors 10 are used.

Damit das von den Leuchtdioden LED1 ... LED5 abgestrahlte Licht und vom Lichtreflektor 10 reflektierte Licht für den Betrachter möglichst weiss und ohne Lichtschatten erscheint, wird der Druckknopf 4 aus lichtdurchlässigen Polycarbonaten mit weisser Tönung gefertigt. Als Lichtquelle sind Leuchtdioden LED1 ... LED5 vorgesehen, die beispielsweise Licht mit einer Wellenlänge von 590 nm aussenden. Grün-, rot- oder andersfarbige Leuchtdioden LED1 ... LED5 werden je nach Bedarf eingesetzt.In order that the light emitted by the light emitting diodes LED1 ... LED5 and light reflected by the light reflector 10 appear as white as possible and without light shadow for the viewer, the push button 4 is made of translucent polycarbonates with a white tint. Light-emitting diodes LED1 ... LED5 are provided as light sources, which, for example, emit light with a wavelength of 590 nm. Green, red or other colored LEDs LED1 ... LED5 are used as required.

Das in Fig. 5 dargestellte elektrische Schaltbild zeigt eine Serieschaltung von Leuchtdioden LED1 ... LED5, die am einen Brückenzweig eines durch die Dioden D1 ... D4 gebildeten Brückengleichrichters liegen. Der andere Brückenzweig ist mit den Anschlussdrähten L1;L2 verbunden, an denen die Versorgungsspannung von bis zu 120 V AC anliegt. Anstelle von Leuchtdioden sind Brücken vorgesehen, falls nicht alle Diodenplätze ausgerüstet werden.The electrical circuit diagram shown in FIG. 5 shows a series circuit of light-emitting diodes LED1 ... LED5 which are located on a bridge branch of a bridge rectifier formed by the diodes D1 ... D4. The other bridge branch is connected to the connecting wires L1; L2, to which the supply voltage of up to 120 V AC is applied. Instead of light-emitting diodes, bridges are provided if not all diode locations are equipped.
