Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur berührungslosen Steuerung einer Lichtquelle gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a device for the contactless control of a Light source according to the preamble of claim 1.
Lichtquellen z. B. in Form von Stehleuchten oder Schreibtischleuchten mit eingebautem mechanischen Schalter oder Sensorschalter zum Schalten der Leuchte sind beispielsweise aus dem Verkaufsprospekt "Dimm-Sensorette" der Firma INSTA ELEKTRO GMBH & Co. KG, Wefelshohler Straße 35, 58511 Lüdenscheid vom 01.08.1986 bekannt.Light sources e.g. B. in the form of floor lamps or desk lamps with built-in mechanical switch or sensor switch for switching the lamp are known for example from the prospectus "Dimm-Sensorette" from INSTA ELEKTRO GMBH & Co. KG, Wefelshohler Strasse 35 , 58511 Lüdenscheid from 01.08.1986.
Tastdimmer, die bei kurzer Betätigung den Schaltzustand einer Leuchte wechseln und bei längerer Betätigung das verwendete Leuchtmittel dimmen sind ebenfalls bekannt. Beispielsweise wird das Leuchtmittel hierbei zyklisch auf- und abgedimmt. Hinweise hierzu sind im Katalog der Firma INSTA ELEKTRO GMBH & Co. KG, Wefelshohler Straße 35, 58511 Lüdenscheid aus dem Jahr 1996/1997 auf Seite 29 zu finden.Touch dimmers that change the switching status of a lamp when pressed briefly and at prolonged operation dim the illuminant used are also known. For example, the illuminant is cyclically dimmed up and down. Notes on this are in the catalog of INSTA ELEKTRO GMBH & Co. KG, Wefelshohler Straße 35, 58511 Lüdenscheid from 1996/1997 on page 29.
Weiterhin gehören Lichtschranken in den unterschiedlichsten Ausführungsformen zum Stand der Technik (vgl. hierzu "Professionelle Schaltungstechnik", Fanzis-Verlag, Band 3, Seite 290). Diese Lichtschranken können als Reflexlichtschranken oder als Durchgangslichtschranken realisiert werden. Sie verwenden entweder sichtbares Licht oder Infrarotstrahlung. Das Signal kann in verschiedenartigen Formen codiert werden, wie in Fig. 4 beispielhaft dargestellt. Bei geeigneter Auswertung ergibt sich dann bestimmungsgemäß eine Fehlerunterdrückung.Furthermore, light barriers in the most varied of embodiments belong to the state of the art (cf. "Professional circuit technology", Fanzis-Verlag, Volume 3, page 290). These light barriers can be implemented as reflex light barriers or as through light barriers. They use either visible light or infrared radiation. The signal can be encoded in various forms, as exemplified in FIG. 4. With a suitable evaluation, error suppression then results as intended.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur berührungslosen Steuerung einer Lichtquelle zu schaffen, die durch Beeinflussung des Strahlenganges einer Lichtschranke den Ein-Aus-Zustand und den Dimmgrad der Lichtquelle realisiert.The present invention has for its object a device for to create contactless control of a light source by influencing the Beam path of a light barrier, the on-off state and the degree of dimming of the light source realized.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungsmerkmale und Ausführungen der Erfindung sind in der folgenden Figurenbeschreibung und den Unteransprüchen enthalten. Es zeigen:This object is achieved with the features of claim 1. More beneficial Design features and implementations of the invention are as follows Description of the figures and the subclaims included. Show it:
Fig. 1 eine schematische Darstellung der Vorrichtung ohne Beeinflussung des Strahlenganges; Figure 1 is a schematic representation of the device without influencing the beam path.
Fig. 2 eine schematische Darstellung der Vorrichtung bei Beeinflussung des Strahlenganges; Fig. 2 is a schematic representation of the device for influencing the beam path;
Fig. 3 eine schematische Darstellung der Erfindung; Fig. 3 is a schematic representation of the invention;
Fig. 4 ein Diagramm zur Darstellung einer Signalcodierung nach dem Stand der Technik; FIG. 4 shows a diagram to illustrate signal coding according to the prior art; FIG.
Fig. 5 ein Diagramm zur Darstellung eines ersten Dimmverhaltens; Fig. 5 is a diagram showing a first dimming behavior;
Fig. 6 ein Diagramm zur Darstellung eines beliebigen weiteren Dimmverhaltens. Fig. 6 is a diagram showing any other dimming behavior.
In Fig. 1 ist die erfindungsgemäße Vorrichtung schematisch so dargestellt, daß der Strahlengang 14 der Lichtschranke 12 die Lichtquelle 11 nicht beeinflußt, während in Fig. 2 die Vorrichtung beeinflußt wird, im Beispiel durch eine Hand.In Fig. 1, the device according to the invention is shown schematically so that the beam path 14 of the light barrier 12 does not affect the light source 11 , while in Fig. 2 the device is influenced, in the example by a hand.
Fig. 3 zeigt wie die Lichtquelle 11 mit einem im Stand der Technik beschriebenen Tastdimmer 13 angesteuert wird, der wiederum mit dem Ausgang einer Lichtschranke 12 angesteuert wird. Eine weitere erfindungsgemäße Ausgestaltung ergibt sich durch die Verwendung eines Relaisschalters oder elektronischen Schalters anstelle eines Tastdimmers 13. Fig. 3 shows how the light source 11 is controlled with a push button dimmer 13 described in the prior art, which in turn is controlled with the output of a light barrier 12 . Another embodiment of the invention results from the use of a relay switch or electronic switch instead of a touch dimmer 13 .
Bei dem in Fig. 3 dargestellten Ausführungsbeispiel kann es sich um eine Vorrichtung mit dem in Fig. 5 dargestellten Zeitverhalten handeln, das bei längerer bei t1 beginnender Beeinflussung im Auszustand die Lichtquelle 11 zuerst im Zeitpunkt t2 in unterster Dimmstellung einschaltet und nach einer kurzen Verzögerung im Zeitpunkt t3 aufzudimmen beginnt. Bei t4 ist die maximale Helligkeit erreicht, die bis zum Zeitpunkt t5 erhalten bleibt, um den Zustand der Maximalhelligkeit sicherer einstellen zu können. Bei t5 beginnt der Abdimmvorgang bis zum Zeitpunkt t6. Bei t6 ist die minimale Helligkeit erreicht, die bis zum Zeitpunkt t7 erhalten bleibt, um den Zustand der Minimalhelligkeit sicherer einstellen zu können. Beim Zeitpunkt t6 wiederholt sich der Dimmvorgang t3 bis t7 erneut. Der Dimmvorgang kann - wie in Fig. 5 beispielhaft zum Zeitpunkt t8 dargestellt - unterbrochen werden und die eingestellte Helligkeit bleibt eingestellt. Bei Beeinflussung im Einzustand, die kürzer oder gleich einer festzulegenden Zeitdifferenz t10-t9 ist, wird das Gerät zum Zeitpunkt t10 ausgeschaltet.The exemplary embodiment shown in FIG. 3 can be a device with the time behavior shown in FIG. 5, which switches on the light source 11 in the lowest dimming position at time t 2 and after a short period of time when the influence begins in the off state at t 1 for a longer period of time Delay at time t 3 begins to dim. At t 4 , the maximum brightness is reached, which is maintained until time t 5 , in order to be able to set the state of the maximum brightness more reliably. The dimming process begins at t 5 until time t 6 . At t 6 , the minimum brightness is reached, which is maintained until time t 7 , in order to be able to set the state of the minimum brightness more reliably. At time t 6 , the dimming process t 3 to t 7 is repeated. The dimming process can - as shown in FIG. 5 by way of example at time t 8 - be interrupted and the set brightness remains set. If there is an influence in the on-state which is shorter or equal to a time difference t 10 -t 9 to be determined, the device is switched off at time t 10 .
Bei dem in Fig. 3 dargestellten Ausführungsbeispiel kann es sich um eine Vorrichtung mit dem in Fig. 6 dargestellten Zeitverhalten handeln, das bei längerer Beeinflussung im Auszustand ausgeschaltet bleibt, um Fehlbetätigungen zu unterdrücken. Bei Beeinflussung im Auszustand, die kürzer oder gleich einer festzulegenden Zeitdifferenz t2-t1 ist, wird das Gerät zum Zeitpunkt t2 eingeschaltet. Um einen Dimmvorgang einzuleiten, muß das Gerät erneut beeinflußt werden, wie in Fig. 6 beim Zeitpunkt t3 zu sehen ist. Die Vorrichtung dimmt ab dem Zeitpunkt t4 ab, solange sie beeinflußt bleibt der bis zur Minimalhelligkeit beim Zeitpunkt t5, je nachdem, was zuerst erreicht ist. Ein Dimmvorgang mit der jeweils entgegengesetzten Dimmrichtung beginnt bei der nächsten Beeinflussung, wie in Fig. 6 zwischen den Zeitpunkten t6 und t7 verdeutlicht ist. Der Dimmvorgang kann - wie in Fig. 6 beispielhaft zum Zeitpunkt t7 dargestellt - unterbrochen werden und die eingestellte Helligkeit bleibt eingestellt. Bei Beeinflussung im Einzustand, die kürzer oder gleich einer festzulegenden Zeitdifferenz t9-t8 ist, wird die Vorrichtung zum Zeitpunkt t9 ausgeschaltet.The exemplary embodiment shown in FIG. 3 can be a device with the time behavior shown in FIG. 6, which remains switched off in the off state in the event of prolonged interference in order to suppress incorrect operations. If there is an influence in the off state that is shorter or equal to a time difference t 2 -t 1 to be defined, the device is switched on at time t 2 . In order to initiate a dimming process, the device must be influenced again, as can be seen in FIG. 6 at time t 3 . The device dims from time t 4 as long as it remains influenced until the minimum brightness at time t 5 , whichever is reached first. A dimming process with the opposite dimming direction begins with the next influencing, as is shown in FIG. 6 between times t 6 and t 7 . The dimming process can - as shown in FIG. 6 by way of example at time t 7 - be interrupted and the set brightness remains set. If there is an influence in the on-state which is shorter or equal to a time difference t 9 -t 8 to be determined, the device is switched off at time t 9 .
Der Strahlengang 14 der Lichtschranke 12 kann als Orientierungshilfe durch einen sichtbaren gebündelten Lichtpunkt 18 (LED- oder Laserlichtpunkt) verdeutlicht werden (Fig. 3).The beam path 14 of the light barrier 12 can be illustrated as an orientation aid by a visible bundled light spot 18 (LED or laser light spot) ( FIG. 3).
Bei der verwendeten Lichtschranke kann es sich um eine IR-Lichtschranke oder um eine Lichtschranke mit Strahlung im sichtbaren Bereich handeln, bei dem der LED- bzw. Laserstrahl als auszuwertendes Signal mitbenutzt wird.The light barrier used can be an IR light barrier or one Act light barrier with radiation in the visible range, in which the LED or Laser beam is used as a signal to be evaluated.
