Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Ansteuerschaltung für wenigstens eine Leuchtdiode bzw. für wenigstens eine Leuchtdioden-Anordnung.The present invention relates on a control circuit for at least one light emitting diode or for at least one light-emitting diode arrangement.
Das technische Gebiet der vorliegenden Erfindung ist insbesondere das der Ansteuerung von auf Platinen angeordneten Leuchtdioden (LEDs) bspw. mit Konstantstromquellen.The technical field of the present In particular, the invention is the control of circuit boards arranged light emitting diodes (LEDs), for example with constant current sources.
Die Verwendung von LEDs zu Beleuchtungszwecken,
insbesondere in einer Matrixanordnung, um somit einen Art Strahler
zu bilden, ist beispielsweise aus dem Patent
Eine Leuchtdiode
Dabei wird zum Dimmen der Leuchtdiode
In
Aus der Patentanmeldung WO 03/053111 ist es bekannt, dass eine Regelungs-Vorrichtung zur Erzeugung einer gewünschten Lichtfarbe anhand von roten, grünen und blauen Leuchtdioden benutzt werden kann. Die Vorrichtung weist einen Sensor auf zur Erfassung einer von den Leuchtdioden erzeugten Lichtfarbe und zur Messung der Farbkoordinaten des erzeugten Lichts in einem ersten Farbe-Raum. Ein erstes Modul wandelt diese Farbkoordinaten in einen zweiten Farbraum. Ein zweites Modul liefert Referenz-Farbkoordinaten passend zum gewünschten Licht, wobei die Referenz-Farbkoordinaten im zweiten Farbraum ausgedrückt sind. Ein Addierer bildet anschließend Fehler-Farbkoordinaten aus der Differenz zwischen den gewünschten und den erzeugten Lichtfarbekoordinaten. Ein mit dem Addierer zusammengekoppeltes Steuer-Modul erzeugt dann ein Signal zur Steuerung der Leuchtdioden.From patent application WO 03/053111 it is known that a control device for generating a desired Light color based on red, green and blue LEDs can be used. The device has a sensor to detect a light color generated by the light emitting diodes and for measuring the color coordinates of the generated light in one first color space. A first module converts these color coordinates in a second color space. A second module provides reference color coordinates to the desired light, where the reference color coordinates are expressed in the second color space. An adder then forms Error-color coordinates from the difference between the desired and the generated light color coordinates. A control module coupled to the adder then generates a signal to control the LEDs.
Ein bei diesem Stand der Technik zu befürchtendes Problem ist, dass die ständige Entwicklung von neuen LED-Chips mit unterschiedlicher Strombelastbarkeit und die explodierende Produktvielfalt bei Konvertern und LED-Arrays zu Kompatibilitätsproblemen zwischen neuen und alten Produkten und zu erheblicher Komplexitäts-Steigerung für den Anwender führen kann.One with this state of the art to be feared Problem is that the constant Development of new LED chips with different current carrying capacity and the exploding variety of products in converters and LED arrays on compatibility issues between new and old products and a considerable increase in complexity for the Guide users can.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Ansteuerschaltung für LED-Module mit zusätzlichen Regelungs- oder Steuerungs-Kanäle zu schaffen.
