Abstract

The contactless 1R switch, for a room lighting system using LV lamps (7), uses a proximity sensor in the form of a light reflection device (1,2) which responds to the presence of a refractive surface at a distance up in the order of centimetres. The light reflection device is coupled to an integrator (3), a threshold switch (4) and a load switch (6) for the lamp (7). Pref. the switch is operated via a rod carrying an attached reflective disc and incorporates a storage function when the lighting system is switched off. ADVANTAGE - Allows selective switching of individual lamps.

Description

Die Erfindung betrifft einen infrarotgesteuerten berührungslosen Schalter zur Verwendung bei einem Leuchtensystem.The invention relates to an infrared controlled non-contact switch for use with a Lighting system.

Berührungslose Schalter sind seit einigen Jahren in der Konsumgüterelektronik bekannt und werden z.B. bei Hände­ trocknern eingesetzt. Sie arbeiten im allgemeinen mit Infrarot-Lichtschranken. Die Schalter sind meistens als Zeitschalter ausgeführt. Sie werden also nicht direkt zum Ein- und Ausschalten eines Gerätes benutzt.Non-contact switches have been in use for several years Consumer goods electronics are known and are e.g. with hands used dryers. They generally work with Infrared light barriers. The switches are mostly as Time switch executed. So you don't go straight to Switching a device on and off used.

Darüber hinaus ist für Lichtquellen die Verwendung eines infrarotgesteuerten berührungslosen Schalters nach dem Oberbegriff des Patentanspruches aus der Druckschrift DE 28 32 438 A1 bekannt. Bei diesem Schalter ist aber eine individuelle Schaltbarkeit von Einzelniedervolt­ leuchten nicht gegeben. Aus dem Artikel "Universelle Lichtschranke" von HÖRNKE in der Zeitschrift Funkschau 15, 1986, S. 64-67 ist es bekannt, Leuchten über Licht­ schranken mit großer Reichweite zu schalten.In addition, the use of a for light sources infrared controlled contactless switch after the Preamble of the patent claim from the publication DE 28 32 438 A1 known. But with this switch an individual switchability of single low voltage do not shine. From the article "Universelle Light barrier "by HÖRNKE in Funkschau magazine 15, 1986, pp. 64-67 it is known to shine over light to switch barriers with a long range.

Niedervolt-Leuchten werden im allgemeinen primärseitig, mechanisch geschaltet. Zur Steuerung der Raumbeleuchtung von Niedervolt-Leuchtensystemen mit mehreren Leuchten werden entweder mehrere Seile mit getrennten Stromkreisen gespannt oder die Primärspannung des Transformators des Leuchtensystems gedimmt. Low-voltage lights are generally used on the primary side, mechanically switched. For controlling the room lighting of low-voltage lighting systems with multiple lights are either multiple ropes with separate circuits excited or the primary voltage of the transformer of the Lighting system dimmed.  

Niedervolt-Leuchten, insbesondere die an Drahtseilen im Raum aufgespannten, zeichnen sich durch ihr filigranes Design aus. In die Leuchten eingebaute mechanische Schalter würden daher bei Betätigung ungewünschte Schwingungen, eventuell sogar Beschädigungen der Leuchten verursachen. Bei Niedervolt-Leuchtensystemen verzichtet man deshalb auf die Möglichkeit einzelne Leuchten mit Schaltern zu versehen und kann so die Ausleuchtung des Raumes nicht schnell umgestalten. Zur Steuerung der Helligkeit der Raumbeleuchtung werden auch primärseitig Dimmer eingesetzt. Die Versorgungsspannung und damit die Helligkeit der Niedervolt-Lampen wird dabei durch das Dimmen des Transformators herabgesetzt.Low voltage lights, especially those on wire ropes in the Spanned space, are characterized by their filigree Design out. Mechanical built into the lights Switches would therefore be undesirable when actuated Vibrations, possibly even damage to the lights cause. Not used in low-voltage lighting systems one therefore on the possibility of using individual lights To provide switches and can thus the illumination of the Do not remodel the room quickly. To control the Brightness of the room lighting are also primary Dimmer used. The supply voltage and thus the The brightness of the low-voltage lamps is determined by the Dimming of the transformer reduced.

Der Erfindung liegt die Aufgabe zugrunde, Niedervolt- Leuchten eines Systems berührungslos, d.h. ohne mecha­ nische Belastung individuell schaltbar zu machen.The invention is based, low-voltage Illumination of a system without contact, i.e. without mecha make it possible to switch the load individually.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.This object is achieved by the features of Claim 1 solved.

Der Schaltzustand der einzelnen Leuchten kann bei zwischenzeitlichem Ausschalten des gesamten Niedervolt- Leuchtensystems gespeichert werden.The switching status of the individual lights can be temporarily switching off the entire low-voltage Lighting system can be saved.

Für hochhängende Niedervolt-Leuchtensysteme, die nicht mit hochgestreckter Hand erreicht werden können, kann eine Vorrichtung geschaffen werden, die den einzelnen Leuchten zugeordneten Schalter bequem zu betätigen vermag. For high-hanging low-voltage lighting systems that don't can be reached with a raised hand a device can be created that individual Luminaire-assigned switches are easy to operate can  

Bei Annäherung einer reflektierenden Fläche (z.B. der Hand oder des Stabes (8)) an den Schalter auf einige Zentimeter Abstand wird über den Näherungssensor, den Integrator und den Schwellwertschalter ein Impuls ausgelöst, der das Lastschaltelement umschaltet. Das Lastschaltelement wiederum schaltet den Stromkreis der jeweiligen Niedervolt-Leuchte.When a reflective surface (e.g. hand or rod ( 8 )) approaches the switch at a distance of a few centimeters, a pulse is triggered via the proximity sensor, the integrator and the threshold switch, which switches the load switching element. The load switching element in turn switches the circuit of the respective low-voltage lamp.

Bei der Ausführungsform nach Anspruch 2 wird der aktuelle Schaltzustand, auch bei ausgeschalteter Versorgungs­ spannung, durch das bistabile Relais (6) gespeichert.In the embodiment according to claim 2, the current switching state, even when the supply voltage is switched off, is stored by the bistable relay ( 6 ).

Mit Hilfe des in Anspruch 3 gekennzeichneten Stabes (8) ist es möglich, auch bei hochhängenden Niedervolt- Leuchtensystemen, einfach den Schalter zu betätigen. Die an einem Ende des Stabs angebrachte reflektierende Scheibe wird auf einige Zentimeter Abstand dem Schalter genähert, um dessen Schaltzustand zu ändern.With the help of the rod ( 8 ) characterized in claim 3, it is possible to simply operate the switch, even in the case of high-voltage low-voltage lighting systems. The reflective disc attached to one end of the rod is moved a few centimeters away from the switch to change its switching state.

In Fig. 1 ist ein Schaltbild eines Ausführungsbeispiels gezeigt.In Fig. 1, a circuit diagram is shown of an embodiment.

Eine vom Oszillator (1) getaktete Infrarot-Leuchtdiode strahlt permanent ein Lichtsignal aus. Wird dieses Signal von einer Fläche (8) reflektiert, registriert eine Infrarot-Empfangsdiode das Signal und es wird selektiv verstärkt (2). Mit Hilfe des Integrators (3) und des Schwellwertschalters (4) wird ein Impuls geformt, der das Flip-Flop (5) umschaltet. Das Flip-Flop steuert das bistabile Relais (6) an, welches den Stromkreis der Niedervolt-Leuchte (7) unterbricht oder schließt.An infrared light emitting diode clocked by the oscillator ( 1 ) continuously emits a light signal. If this signal is reflected by a surface ( 8 ), an infrared receiver diode registers the signal and it is selectively amplified ( 2 ). With the help of the integrator ( 3 ) and the threshold switch ( 4 ), a pulse is formed which switches the flip-flop ( 5 ). The flip-flop controls the bistable relay ( 6 ), which interrupts or closes the circuit of the low-voltage lamp ( 7 ).
