Description

Es wird eine Steuervorrichtung zur Ansteuerung einer Leuchte angegeben. Darüber hinaus wird eine Leuchte mit einer solchen Steuervorrichtung angegeben.It is specified a control device for controlling a lamp. In addition, a luminaire is specified with such a control device.

Eine zu lösende Aufgabe besteht darin, eine Steuervorrichtung anzugeben, die besonders kostengünstig herstellbar ist.An object to be solved is to provide a control device which is particularly inexpensive to produce.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung umfasst die Steuervorrichtung einen Signaleingang, einen Signalausgang und eine Signalverarbeitungsvorrichtung. Der Signaleingang ist dabei zum Empfang eines Eingangssignals und der Signalausgang zur Ausgabe eines Ausgangssignals eingerichtet. Die Signalverarbeitungsvorrichtung ist dazu eingerichtet, das Eingangssignal zum Ausgangssignal zu verarbeiten.In accordance with at least one embodiment of the control device, the control device comprises a signal input, a signal output and a signal processing device. The signal input is set up to receive an input signal and the signal output to output an output signal. The signal processing device is configured to process the input signal to the output signal.

Beispielsweise handelt es sich bei dem Eingangssignal um ein serielles Eingangssignal. Das Eingangssignal kann dabei die Länge N, gemessen beispielsweise in Bit oder Byte, aufweisen.For example, the input signal is a serial input signal. The input signal can have the length N, measured, for example, in bits or bytes.

Die Signalverarbeitungsvorrichtung ist gemäß zumindest einer Ausführungsform der Steuervorrichtung dazu eingerichtet, das Eingangssignal um ein Steuersignal der Länge n zu verkürzen. Dabei ist n ≤ N.The signal processing device is configured in accordance with at least one embodiment of the control device to shorten the input signal by a control signal of length n. Where n ≤ N.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist der Signalausgang zur Ausgabe eines Ausgangssignals eingerichtet. Das Ausgangssignal umfasst das um das Steuersignal verkürzte Eingangssignal. Das Ausgangssignal kann dabei ebenfalls die Länge N aufweisen. Die n Stellen des ursprünglichen Eingangssignals, welche das Steuersignal bilden, sind im Ausgangssignal dann beispielsweise vollständig durch n Stellen im Signal mit niedrigem Pegel (logisch 0) oder hohem Pegel (logisch 1) ersetzt. Mit anderen Worten ist das Ausgangssignal dann das um die Information des Steuersignals verkürzte Eingangssignal.In accordance with at least one embodiment of the control device, the signal output is set up to output an output signal. The output signal comprises the input signal shortened by the control signal. The output signal may also have the length N. The n digits of the original input signal forming the control signal are then completely replaced in the output signal by, for example, n places in the low-level (logic 0) or high-level (logical 1) signal. In other words, the output signal is then the input signal shortened by the information of the control signal.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung umfasst die Signalverarbeitungsvorrichtung einen UART (Abkürzung für Universal Asynchronous Receiver Transmitter) und ein Schaltelement. Bei dem UART handelt es sich um ein elektronisches Bauelement, das zur Realisierung von digitalen seriellen Schnittstellen dient. Die UART-Schnittstelle dient dabei zum Senden und Empfangen von Daten, vorliegend zum Empfangen des Eingangssignals.In accordance with at least one embodiment of the control device, the signal processing device comprises a UART (abbreviation for Universal Asynchronous Receiver Transmitter) and a switching element. The UART is an electronic device used to implement digital serial interfaces. The UART interface serves for transmitting and receiving data, in this case for receiving the input signal.

Bei dem Schaltelement handelt es sich beispielsweise um ein UND-Gatter oder um einen nicht-invertierenden Puffer ("non-inverting Buffer").The switching element is, for example, an AND gate or a non-inverting buffer.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist der UART dazu eingerichtet, beim Eingang des Steuersignals das Schaltelement zu schalten, sodass das Schaltelement das Eingangssignal um das Steuersignal verkürzt.In accordance with at least one embodiment of the control device, the UART is set up to switch the switching element at the input of the control signal, so that the switching element shortens the input signal by the control signal.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung zur Ansteuerung einer Leuchte umfasst die Steuervorrichtung einen Signaleingang, einen Signalausgang und eine Signalverarbeitungsvorrichtung, bei der der Signaleingang zum Empfang eines seriellen Eingangssignals der Länge N eingerichtet ist, die Signalverarbeitungsvorrichtung zur Verkürzung des Eingangssignals um ein Steuersignal der Länge n eingerichtet ist und der Signalausgang zur Ausgabe eines Ausgangssignals, das das um das Steuersignal verkürzte Eingangssignal umfasst, eingerichtet ist. Dabei umfasst die Signalverarbeitungsvorrichtung einen UART und ein Schaltelement, wobei der UART dazu eingerichtet ist, beim Empfang des Steuersignals das Schaltelement zu schalten, sodass das Schaltelement das Eingangssignal um das Steuersignal verkürzt.In accordance with at least one embodiment of the control device for activating a luminaire, the control device comprises a signal input, a signal output and a signal processing device in which the signal input is set up to receive a serial input signal of length N, the signal processing device is set up to shorten the input signal by a control signal of length n is and the signal output to output a Output signal, which includes the shortened by the control signal input signal is set up. In this case, the signal processing device comprises a UART and a switching element, wherein the UART is adapted to switch on receiving the control signal, the switching element, so that the switching element shortens the input signal by the control signal.

Die Steuervorrichtung ist dabei beispielsweise zur Verarbeitung eines so genannten DMX (Abkürzung für Digital Multiplex)-Signals oder eines DMX-ähnlichen Signals eingerichtet.The control device is configured, for example, for processing a so-called DMX (abbreviation for digital multiplex) signal or a DMX-like signal.

Ein DMX-Signal ist hierbei ein serielles Signal, bei dem Daten mit einer Übertragungsrate von 250 kbit/s übermittelt werden. Das DMX-Signal umfasst 513 Bytes, wobei das erste Byte ein Startcode ist, der die Art der zu übermittelnden Daten einem Empfänger mitteilt. Das DMX-Signal kann beispielsweise über eine drei-polige oder eine fünf-polige Datenleitung übermittelt werden.A DMX signal is a serial signal in which data is transmitted at a transmission rate of 250 kbit / s. The DMX signal comprises 513 bytes, the first byte being a start code which tells the type of data to be transmitted to a receiver. The DMX signal can be transmitted, for example, via a three-pole or a five-pole data line.

Bei einem DMX-ähnlichen Signal kann es sich vorliegend um ein Signal handeln, bei dem die Übertragungsrate erhöht ist. Beispielsweise weist das DMX-ähnliche Signal eine Übertragungsrate von > 500 kbit/s, zum Beispiel von 1 Mbit/s auf. DMX-ähnliche Signale schließen vorliegend auch eine bidirektionale Datenübermittlung ein, zum Beispiel über RDM (Remote Device Management). Über RDM ist eine bidirektionale Kommunikation, insbesondere über DMX-Datenverbindungen von Komponenten untereinander möglich.In the case of a DMX-like signal, this may be a signal in which the transmission rate is increased. For example, the DMX-like signal has a transmission rate of> 500 kbit / s, for example of 1 Mbit / s. In the present case, DMX-like signals also include bidirectional data transmission, for example via RDM (Remote Device Management). Via RDM bidirectional communication is possible, in particular via DMX data connections between components.

Das DMX-Signal oder das DMX-ähnliche Signal eignet sich dabei besonders gut zur Ansteuerung einer Leuchte, die zumindest einen Leuchtdiodenchip, vorzugsweise eine Vielzahl von Leuchtdiodenchips, als Lichtquellen umfasst. Beispielsweise kann ein Steuersignal zur Ansteuerung eines einzelnen Leuchtdiodenchips eine Länge von 1 Byte aufweisen. Die Adressierung des Bytes ist für ein DMX-Signal oder ein DMX-ähnliches Signal jedoch nicht möglich. Vorliegend nutzt die Steuervorrichtung daher ein so genanntes Auto-Addressing-Verfahren, bei dem die Signalverarbeitungsvorrichtung der Steuervorrichtung das Steuersignal aus dem seriellen Eingangssignal entnimmt. Das Steuersignal weist dabei die Länge auf, die zur Ansteuerung der von der Steuervorrichtung verwalteten Lichtquellen, zum Beispiel Leuchtdiodenchips, benötigt wird. Umfasst die Leuchte beispielsweise eine einzige RGB-LED mit einem roten, einem grünen und einem blauen Leuchtdiodenchip, so entnimmt die Steuervorrichtung ein n = 3 Byte langes Steuersignal und gibt das um das Steuersignal verkürzte Eingangssignal als Ausgangssignal beispielsweise an eine weitere Steuervorrichtung weiter, die zur Ansteuerung einer weiteren Leuchte vorgesehen ist.The DMX signal or the DMX-like signal is particularly well suited for driving a lamp, the at least one LED chip, preferably a plurality of LED chips, as light sources comprises. For example, a control signal for driving a single LED chip may have a length of 1 byte. Addressing the byte is not possible for a DMX signal or a DMX-like signal. In the present case, therefore, the control device uses a so-called auto-addressing method, in which the signal processing device of the control device extracts the control signal from the serial input signal. In this case, the control signal has the length which is needed to control the light sources, for example light-emitting diode chips, managed by the control device. If, for example, the luminaire comprises a single RGB LED with a red, a green and a blue LED chip, then the control device extracts a n = 3-byte control signal and forwards the input signal shortened by the control signal as an output signal, for example, to a further control device which is used for Control of a further light is provided.

Zur Durchführung eines derartigen Auto-Addressing-Verfahrens können prinzipiell relativ teure integrierte Schaltungen, wie beispielsweise so genannte FPGAs (Abkürzung für Field Programmable Gate Array) oder so genannte ASICs (Application-Specific Integrated Circuit) zum Einsatz kommen.In principle, relatively expensive integrated circuits, such as, for example, so-called FPGAs (abbreviation for field programmable gate array) or so-called ASICs (application-specific integrated circuit) can be used to carry out such an auto-addressing method.

Vorliegend wird jedoch eine Möglichkeit angegeben, wie eine Steuervorrichtung, die zum Auto-Addressing bei der Benutzung eines seriellen Datenprotokolls geeignet ist, möglichst kostengünstig realisiert werden kann. Dabei kann zum Auto-Addressing beispielsweise ein einfacher, kostengünstiger Mikrocontroller Verwendung finden. Das heißt, die vorliegende Steuervorrichtung ist auch dadurch gekennzeichnet, dass zum Auto-Addressing ein Mikrocontroller, vorzugsweise ein einziger Mikrocontroller pro Leuchte Verwendung, findet. Gemäß zumindest einer Ausführungsform der Steuervorrichtung sind der UART und das Schaltelement zum Empfang des Eingangssignals eingerichtet. Beispielsweise wird das Eingangssignal sowohl auf den UART als auch auf das Schaltelement gelegt. Der UART schaltet das Schaltelement beim Auftreten des Steuersignals, sodass das Schaltelement das Eingangssignal um das Steuersignal verkürzen kann. Es resultiert am Schaltelement ausgangsseitig dann das um das Steuersignal verkürzte Eingangssignal als Ausgangssignal.In the present case, however, a possibility is given of how a control device which is suitable for auto-addressing when using a serial data protocol can be realized as inexpensively as possible. For example, a simple, cost-effective microcontroller can be used for auto-addressing. That is, the present control device is also characterized in that for auto-addressing a microcontroller, preferably a single microcontroller per lamp use finds. In accordance with at least one embodiment of the control device, the UART and the switching element are set up to receive the input signal. For example, the input signal is applied to both the UART and the switching element. The UART switches the switching element upon the occurrence of the control signal so that the switching element can shorten the input signal by the control signal. This results in the switching element on the output side then shortened by the control signal input signal as an output signal.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist der UART zur Erkennung eines Break-Signals eingerichtet, wobei das Break-Signal den Beginn des Steuersignals anzeigt.In accordance with at least one embodiment of the control device, the UART is set up to detect a break signal, the break signal indicating the start of the control signal.

Beispielsweise kann es sich bei dem Break-Signal um ein Signal mit niedrigem Pegel (logisch 0) handeln, das vom UART als invalides Datenbyte mit fehlendem Stoppbit erkannt wird. Bei einem DMX-Paket beträgt die Länge des Break-Signals wenigstens 88 µs, was 22 Bitlängen mit einer Bitlänge von 4 µs entspricht. Aufgrund des Break-Signals kann der UART das Schaltelement beispielsweise mittels eines Interrupt-Signals schalten.For example, the break signal may be a low level signal (logic 0) that is recognized by the UART as an invalid data byte with a missing stop bit. For a DMX packet, the length of the break signal is at least 88 μs, which corresponds to 22 bit lengths with a bit length of 4 μs. Due to the break signal, the UART can switch the switching element, for example by means of an interrupt signal.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung umfasst die Steuervorrichtung, zum Beispiel die Signalverarbeitungsvorrichtung, eine Capture/Compare-Einheit. Die Capture/Compare-Einheit ist dazu eingerichtet, die Dauer des Break-Signals zu bestimmen. Dies erweist sich als besonders vorteilhaft, wenn als Datenprotokoll ein DMX-ähnliches Protokoll mit beispielsweise einer erhöhten Datenübertragungsrate von zum Beispiel größer oder gleich 500 kbit/s Verwendung findet.In accordance with at least one embodiment of the control device, the control device, for example the signal processing device, comprises a capture / compare unit. The capture / compare unit is set up to determine the duration of the break signal. This proves to be particularly advantageous if the data protocol used is a DMX-like protocol with, for example, an increased data transmission rate of, for example, greater than or equal to 500 kbit / s.

Der hier beschriebenen Steuervorrichtung liegt dabei unter anderem die Idee zugrunde, anhand der Dauer des Break-Signals eine Erkennung des verwendeten Übertragungsprotokolls zur Übertragung des Eingangssignals für die Steuervorrichtung zu ermöglichen. Mit anderen Worten wird das Übertragungsprotokoll der Steuervorrichtung durch eine Dauer des Break-Signals angezeigt, die beispielsweise unterhalb der für DMX-Pakete üblichen Mindestdauer von 88 µs liegt.Among other things, the control device described here is based on the idea of enabling detection of the transmission protocol used for transmitting the input signal for the control device on the basis of the duration of the break signal. In other words, the transmission protocol of the control device is indicated by a duration of the break signal, which is, for example, below the usual minimum duration of 88 μs for DMX packets.

Vorliegend ist die Steuervorrichtung, insbesondere die Signalverarbeitungsvorrichtung der Steuervorrichtung, dazu eingerichtet, ein Break-Signal mit einer Dauer von ≤70 µs, zum Beispiel von wenigstens 50 µs und höchstens 70 µs zu erkennen und anhand der Dauer des Break-Signals das zur Übertragung des Eingangssignals verwendete Protokoll zu bestimmen. Mit anderen Worten ist die Steuervorrichtung also dazu eingerichtet, aus der Dauer des Break-Signals das zur Übertragung des Eingangssignals verwendete Protokoll zu bestimmen. Dabei ist es möglich, dass das Break-Signal ausschließlich über seine Länge, also ausschließlich unter Verwendung der Capture/Compare-Einheit detektiert wird.In the present case, the control device, in particular the signal processing device of the control device, is adapted to detect a break signal having a duration of ≦ 70 μs, for example of at least 50 μs and not more than 70 μs and based on the duration of the break signal that for transmitting the Input signal used to determine protocol. In other words, the control device is thus configured to determine from the duration of the break signal the protocol used for transmitting the input signal. It is possible that the break signal is detected exclusively over its length, that is, exclusively using the capture / compare unit.

Damit erlaubt die hier beschriebene Steuervorrichtung auch die Verwendung von DMX-ähnlichen Übertragungsprotokollen, die Übertragungsraten von 500 kbit/s und mehr aufweisen können.Thus, the control device described herein also allows the use of DMX-like transmission protocols, which may have transmission rates of 500 kbit / s and more.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist der UART eine Komponente eines Mikrocontrollers. Ferner ist es möglich, dass auch die Capture/Compare-Einheit eine Komponente eines Mikrocontroller ist. Der UART und die Capture/Compare-Einheit können dabei Komponenten des gleichen Mikrocontrollers sein, der neben der Adressierung, also der Extraktion des für die Leuchte vorgesehenen Steuersignals, auch weitere Steuerfunktionen für die Leuchte übernehmen kann.In accordance with at least one embodiment of the control device, the UART is a component of a microcontroller. Furthermore, it is also possible for the capture / compare unit to be a component of a microcontroller. The UART and the capture / compare unit can be components of the same microcontroller, which in addition to the addressing, so the extraction of the control signal provided for the lamp, can also take over further control functions for the luminaire.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist das Schaltelement außerhalb des Mikrocontrollers angeordnet. Auf diese Weise ist es möglich, einen Standard-Mikrocontroller zu verwenden, was eine besonders kostengünstige Steuervorrichtung ermöglicht.In accordance with at least one embodiment of the control device, the switching element is arranged outside the microcontroller. In this way it is possible to use a standard microcontroller, which allows a particularly cost-effective control device.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung umfasst die Signalverarbeitungsvorrichtung der Steuervorrichtung, die zur Verkürzung des Eingangssignals um ein Steuersignal der Länge n eingerichtet ist, einen einzigen UART. Prinzipiell wäre es zwar möglich, einen zweiten UART zur Datenausgabe zu verwenden. Ein zweiter UART zur Datenausgabe verzögert jedoch die Weitergabe an die nachfolgenden Steuervorrichtungen der nachfolgenden Leuchten. Es müsste zuerst ein Datum entgegengenommen werden, in den Puffer gelegt und anschließend mit dem zweiten UART serialisiert werden. Diese Vorgehensweise erwirkt einen zeitlichen Verzug zum Eingangssignal. Bei vielen, hintereinander angeordneten Leuchten addieren sich diese Verzögerungen, was zu sichtbaren Verzögerungen beispielsweise bei der Darstellung von Videobildern auf den Leuchten führen kann.In accordance with at least one embodiment of the control device, the signal processing device of the control device, which is set up to shorten the input signal by a control signal of length n, comprises a single UART. In principle, it would be possible to use a second UART for data output. However, a second UART for data output delays the transfer to the subsequent control devices of the following lights. It would first have to be taken a date, placed in the buffer and then serialized with the second UART. This procedure obtains a time delay to the input signal. For many, consecutively arranged lights add these delays, which can lead to visible delays, for example, in the presentation of video images on the lights.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung umfasst die Steuervorrichtung eine Gamma-Korrektureinheit, die dazu eingerichtet ist, das Steuersignal mit einer Augenempfindlichkeitskurve zu verarbeiten.In accordance with at least one embodiment of the control device, the control device comprises a gamma correction unit that is configured to process the control signal with an eye sensitivity curve.

Gemäß zumindest einer Ausführungsform der Steuervorrichtung ist die Gamma-Korrektureinheit dazu eingerichtet, das Steuersignal oder einen Teil des Steuersignals, das für beispielsweise genau einen Leuchtdiodenchip vorgesehen ist, und eine Länge von höchstens 10 Bit, insbesondere höchstens oder genau 8 Bit aufweist, auf ein korrigiertes Steuersignal mit einer Länge von mindestens 12 Bit, insbesondere auf mindestens oder genau 14 Bit, zu erweitern. Insbesondere für kleine, beispielsweise an einen Leuchtdiodenchip abzugebende Stromstärken und somit für kleine Helligkeitswerte des von dem Leuchtdiodenchip im Betrieb erzeugten Lichts kann auf diese Weise eine ausreichende Anpassung an die vergleichsweise hohe Empfindlichkeit des menschlichen Auges für geringe Helligkeiten erzielt werden. Insbesondere für solche kleine Helligkeiten ist ein Steuersignal der Länge 8 Bit für einen einzelnen Leuchtdiodenchip unzulänglich, da bei kleinen Helligkeiten das menschliche Auge vergleichsweise empfindlich ist. Durch die Gamma-Korrektureinheit der Steuervorrichtung wird das beispielsweise 8 Bit lange Signal in ein Signal mit mehr Bit, beispielsweise 14 Bit, interpoliert.In accordance with at least one embodiment of the control device, the gamma correction unit is set up to control the control signal or a part of the control signal that is used for For example, exactly one light-emitting diode chip is provided, and has a length of at most 10 bits, in particular at most or exactly 8 bits, to a corrected control signal with a length of at least 12 bits, in particular to at least or exactly 14 bits to expand. In particular for small currents to be output to a light-emitting diode chip, for example, and thus for small brightness values of the light generated by the light-emitting diode chip during operation, sufficient adaptation to the comparatively high sensitivity of the human eye for low brightnesses can be achieved in this way. In particular for such small brightnesses, a control signal of length 8 bits is inadequate for a single light-emitting diode chip, since the human eye is comparatively sensitive at low brightnesses. The gamma correction unit of the control device interpolates the signal, which is for example 8 bits long, into a signal with more bits, for example 14 bits.

Es wird darüber hinaus eine Leuchte angegeben. Die Leuchte umfasst zumindest eine Steuervorrichtung, wie sie hier beschrieben ist, das heißt sämtliche für die Steuervorrichtung beschriebenen Merkmale sind auch für die Leuchte offenbart.It is also indicated a light. The luminaire comprises at least one control device as described here, that is, all the features described for the control device are also disclosed for the luminaire.

Ferner umfasst die Leuchte zumindest einen Leuchtdiodenchip, vorzugsweise eine Vielzahl von Leuchtdiodenchips. Die Leuchtdiodenchips werden dabei in Abhängigkeit vom Steuersignal oder vom korrigierten Steuersignal bestromt. Die Steuervorrichtung ist dabei geeignet, das Steuersignal für die Leuchtdiodenchips der Leuchte aus dem Eingangssignal zu extrahieren und das um das Steuersignal verkürzte Eingangssignal als Ausgangssignal an einer weitere Steuervorrichtung, die beispielsweise Teil einer gleichartigen Leuchte ist, weiterzugeben.Furthermore, the luminaire comprises at least one light-emitting diode chip, preferably a multiplicity of light-emitting diode chips. The LED chips are energized in response to the control signal or the corrected control signal. The control device is suitable for extracting the control signal for the light-emitting diode chips of the luminaire from the input signal and the input signal shortened by the control signal as an output signal at another one Control device, for example, part of a similar light, pass.

Im Folgenden werden die hier beschriebene Steuervorrichtung sowie die hier beschriebene Leuchte anhand von Ausführungsbeispielen und den dazugehörigen Figuren näher erläutert.

Gleiche, gleichartige oder gleich wirkende Elemente sind in den Figuren mit denselben Bezugszeichen versehen. Die Figuren und die Größenverhältnisse der in den Figuren dargestellten Elemente untereinander sind nicht als maßstäblich zu betrachten. Vielmehr können einzelne Elemente zur besseren Darstellbarkeit und/oder zum besseren Verständnis übertrieben groß dargestellt sein.The same, similar or equivalent elements are provided in the figures with the same reference numerals. The figures and the proportions of the elements shown in the figures with each other are not to be considered to scale. Rather, individual elements may be exaggerated in size for better representability and / or better understanding.

In der Figur 1 ist anhand einer schematischen Draufsicht eine hier beschriebene Steuervorrichtung gezeigt. Die Steuervorrichtung 100 weist einen Signaleingang 101 auf. Durch den Signaleingang 101 gelangt ein Eingangssignal 21 in die Steuervorrichtung 100. Bei dem Eingangssignal 21 handelt es sich vorliegend um ein serielles Datensignal, das beispielsweise durch ein DMX-Signal oder ein DMX-ähnliches Signal gebildet ist. Das Eingangssignal 21 umfasst ein Steuersignal 23.In the FIG. 1 is shown with reference to a schematic plan view of a control device described here. The control device 100 has a signal input 101. An input signal 21 passes through the signal input 101 into the control apparatus 100. The input signal 21 in the present case is a serial data signal, which is for example a DMX signal or a DMX-like signal Signal is formed. The input signal 21 comprises a control signal 23.

Die Steuervorrichtung 100 umfasst weiter eine Signalverarbeitungseinrichtung 104. Die Signalverarbeitungsvorrichtung 104 ist dazu vorgesehen, das Eingangssignal 21 um das Steuersignal 23 der Länge n zu verkürzen und das Steuersignal 23 zu extrahieren. Vorliegend umfasst die Signalverarbeitungsvorrichtung 104 dazu einen UART 11. Ferner umfasst die Signalverarbeitungsvorrichtung 104 ein Schaltelement 10.The control device 100 further comprises a signal processing device 104. The signal processing device 104 is provided to shorten the input signal 21 by the control signal 23 of length n and to extract the control signal 23. In the present case, the signal processing device 104 comprises a UART 11 for this purpose. Furthermore, the signal processing device 104 comprises a switching element 10.

Bei dem Schaltelement 10 kann es sich zum Beispiel um ein Gatter oder einen nicht-invertierenden Puffer handeln. Als nicht-invertierender Puffer kommt zum Beispiel das Bauteil SN74HC125 von Texas Instruments zum Einsatz. Beim Ausführungsbeispiel der Figur 1 handelt es sich beim Schaltelement 10 insbesondere um ein logisches UND-Gatter.The switching element 10 may be, for example, a gate or a non-inverting buffer. As a non-inverting buffer, for example, the component SN74HC125 from Texas Instruments is used. In the embodiment of FIG. 1 in particular, the switching element 10 is a logical AND gate.

Optional kann die Signalverarbeitungsvorrichtung 104 eine Capture/Compare-Einheit 12 umfassen.Optionally, the signal processing device 104 may include a capture / compare unit 12.

Die Steuervorrichtung 100 umfasst ferner Treiber 13, 14 am Signaleingang beziehungsweise am Signalausgang. Die Steuervorrichtung 100 umfasst einen Signalausgang 102, an dem das Ausgangssignal 22, welches das um das Steuersignal verkürzte Eingangssignal 21 umfasst, ausgegeben wird.The control device 100 further comprises drivers 13, 14 at the signal input or at the signal output. The control device 100 comprises a signal output 102, at which the output signal 22, which comprises the input signal 21 shortened by the control signal, is output.

Im Betrieb der Steuervorrichtung 100 gelangt das Eingangssignal 21 über den Treiber 13 zum UART und zum Schaltelement. Das heißt, sowohl UART und Schaltelement sind mit dem Signaleingang 101 verbunden und zum Empfang des Eingangssignals 21 eingerichtet. Zum Beispiel der UART erkennt im Eingangssignal ein Break-Signal, welches den Beginn des Steuersignals anzeigt. Der UART 11 schaltet daraufhin das Schaltelement 10 und das Schaltelement 10 verkürzt beispielsweise durch eine logische UND-Operation das Eingangssignal 21 um das Steuersignal 23. Am Ausgang des Schaltelements 10 wird das Ausgangssignal 22 geliefert, welches am Signalausgang 102 die Steuervorrichtung 100 in Richtung beispielsweise einer nachfolgenden Steuervorrichtung verlässt.During operation of the control device 100, the input signal 21 reaches the UART and the switching element via the driver 13. That is, both UART and switching element are connected to the signal input 101 and arranged to receive the input signal 21. For example, the UART detects in the input signal a break signal, which the Indicates the beginning of the control signal. The UART 11 then switches the switching element 10 and the switching element 10 shortens, for example by a logical AND operation, the input signal 21 to the control signal 23. At the output of the switching element 10, the output signal 22 is supplied, which at the signal output 102, the control device 100 in the direction of, for example downstream control device leaves.

Optional kann die Steuervorrichtung 100 und dabei insbesondere die Signalverarbeitungsvorrichtung 104 die Capture/Compare-Einheit 12 umfassen, welche die Dauer des Break-Signals bestimmen kann. Beispielsweise kann es sich bei dem Break-Signal dann um einen niedrigen Pegel (logisch 0) mit einer Länge von ≤70 µs handeln. Die Erkennung der Länge des Break-Signals erlaubt die Verwendung beispielsweise von schnellen, DMX-ähnlichen Protokollen.Optionally, the control device 100 and in particular the signal processing device 104 may include the capture / compare unit 12, which may determine the duration of the break signal. For example, the break signal can then be a low level (logical 0) with a length of ≤70 μs. Detecting the length of the break signal allows the use of, for example, fast, DMX-like protocols.

Vorliegend sind der UART 11 und die Capture/Compare-Einheit 12 Bestandteil eines Mikrocontrollers 1. Das Schaltelement 10 ist außerhalb des Mikrocontrollers 1 angeordnet.In the present case, the UART 11 and the capture / compare unit 12 are part of a microcontroller 1. The switching element 10 is arranged outside the microcontroller 1.

Der Mikrocontroller 1 kann optional die Gamma-Korrektureinheit 15 umfassen, die dazu eingerichtet ist, das extrahierte Steuersignal 23 auf ein wie oben beschriebenes erweitertes, korrigiertes Steuersignal 23' zu verlängern.The microcontroller 1 may optionally include the gamma correction unit 15, which is adapted to extend the extracted control signal 23 to an extended, corrected control signal 23 'as described above.

Die Steuervorrichtung 100 umfasst weiter einen Steuersignal-Ausgang 103, an dem das Steuersignal 23 oder das korrigierte Steuersignal 23' die Steuervorrichtung 100 verlässt. Das Steuersignal 23 beziehungsweise das korrigierte Steuersignal 23' können dann beispielsweise zur Ansteuerung einer Pulsweitenmodulationsschaltung Verwendung finden, welche ihrerseits an sie angeschlossene Leuchtdiodenchips betreibt.The control device 100 further comprises a control signal output 103, at which the control signal 23 or the corrected control signal 23 'leaves the control device 100. The control signal 23 or the corrected control signal 23 'can then be used, for example, to control a pulse width modulation circuit, which in turn operates light emitting diode chips connected to it.

Die Pulsweitenmodulationsschaltung kann dabei ebenfalls Teil der Steuervorrichtung sein und beispielsweise auch in den Mikrocontroller 1 integriert sein.The pulse width modulation circuit may also be part of the control device and be integrated into the microcontroller 1, for example.

In der Figur 2 ist anhand einer schematischen Draufsicht ein weiteres Ausführungsbeispiel einer hier beschriebenen Steuervorrichtung näher erläutert. Im Unterschied zum Ausführungsbeispiel der Figur 1 ist das Schaltelement 10 durch einen nicht-invertierenden Puffer gebildet. Da der Puffer "Tri-State" ist, also neben "0" und "1" einen dritten Zustand einnehmen kann, umfasst die Steuervorrichtung 100 zusätzlich einen sogenannten "Pull Up" Widerstand, der für einen definierten Signalpegel sorgen kann.In the FIG. 2 a further embodiment of a control device described here is explained in more detail with reference to a schematic plan view. In contrast to the embodiment of FIG. 1 For example, the switching element 10 is formed by a non-inverting buffer. Since the buffer is "tri-state", ie a third state can be assumed next to "0" and "1", the control device 100 additionally comprises a so-called "pull-up" resistor, which can provide a defined signal level.

Im Betrieb arbeitet eine Steuervorrichtung 100 gemäß den Figuren 1 oder 2 beispielsweise wie folgt:

  1. 1. Das Steuerelement 10 wird beim Systemstart über den Steuereingang (zum Beispiel /OE) eingeschaltet und am Eingang anliegende Daten werden mit einer minimalen Verzögerung ausgegeben. Dies geschieht zum Beispiel mittels eines Mikrocontroller I/O 16.
  2. 2. Der Mikrocontroller 1 detektiert ein Break-Signal (zum Beispiel ein DMX-Break) und lässt den Steuereingang des Steuerelements 10 unverändert. Die Erkennung des Break-Signals kann dabei auf zumindest eine der folgenden Weisen erfolgen:
    1. a. Das Break-Signal wird über einen UART-Fehler (Stoppbit logisch Null) erkannt und/oder
    2. b. die Capture/Compare-Einheit 12 des Mikrocontrollers 1 misst die Länge des Break-Signals aus.
  3. 3. Der Startcode des Signals wird interpretiert und das Steuerelement 10 entsprechend geschaltet:
    1. a. Entspricht der Startcode Lichtsteuerinformationen, also einem Steuersignal 23, so wird das Steuerelement 10 - zum Beispiel der Puffer - deaktiviert.
    2. b. Werden nachfolgend andersgeartete Steuerinformationen gesendet, so bleibt das Steuerelement 10 aktiv und erst ein erneutes Break-Signal mit nachfolgendem Startcode würde zu einem erneuten Entscheidungsprozess führen.
  4. 4. Sind alle für die Leuchte benötigten Informationen empfangen, ist also das Steuersignal 23 empfangen, so wird das Steuerelement 10 eingeschaltet, so dass nachfolgenden Daten unverändert die nächste Steuereinrichtung erreichen.
In operation, a controller 100 operates according to the FIGS. 1 or 2 for example, as follows:
  1. 1. The controller 10 is turned on at system startup via the control input (eg, / OE) and data applied to the input is output with a minimum delay. This happens for example by means of a microcontroller I / O 16.
  2. 2. The microcontroller 1 detects a break signal (for example a DMX break) and leaves the control input of the control element 10 unchanged. The detection of the break signal can take place in at least one of the following ways:
    1. a. The break signal is detected via a UART error (stop bit logical zero) and / or
    2. b. the capture / compare unit 12 of the microcontroller 1 measures the length of the break signal.
  3. 3. The start code of the signal is interpreted and the control 10 is switched accordingly:
    1. a. If the start code corresponds to light control information, that is to say a control signal 23, the control element 10-for example the buffer-is deactivated.
    2. b. If differently-type control information is subsequently sent, then the control element 10 remains active and only a renewed break signal with the following start code would lead to a new decision-making process.
  4. 4. Are all the information required for the lamp received, that is, the control signal 23 is received, the control element 10 is turned on, so that subsequent data unchanged reach the next control device.

Das Zusammenspiel zwischen dem Mikrocontroller und beispielsweise dem als nicht-invertierenden Puffer ausgebildeten Steuerelement 10 ist dabei wie folgt:The interaction between the microcontroller and, for example, the control element 10 designed as a non-inverting buffer is as follows:

Das Eingangssignal 21 hat beispielsweise zwei Stoppbits, die logisch "1" sind. Während diesen Stoppbits muss das Steuerelement 10 manipuliert werden. Geschieht dies nicht während der Stoppbits, so entstehen unerwünschte Störungen, welche nachfolgende Steuervorrichtungen 100 irritieren könnten.For example, the input signal 21 has two stop bits that are logic "1". During these stop bits, the control 10 must be manipulated. If this does not happen during the stop bits, unwanted disturbances arise which subsequent control devices 100 could irritate.

Gemäß einer ersten Ausgestaltung kann der Mikrocontroller ein Interrupt schon beim Einlesen des zweiten Stoppbits erzeugen, zeitlich also etwa in der Mitte des Bits. In diesem Fall bleibt der Interrupt-Routine genügend Zeit mittels einer Schnittstelle, zum Beispiel eines "General Purpose IO", das Steuerelement 10 ein- oder auszuschalten.According to a first embodiment, the microcontroller can generate an interrupt even when the second stop bit is read in, ie, approximately in the middle of the bit. In this case, the interrupt routine will have enough time by means of an interface, for example a "General Purpose IO", to turn the control 10 on or off.

Gemäß einer alternativen Ausgestaltung ist die Interrupt Latency des Mikrocontrollers zu groß und das Steuerelement 10 kann nicht ausreichend schnell geschaltet werden. Das Steuerelement wird in diesem Fall bevorzugt schon beim Erreichen des ersten Stoppbits geschaltet.According to an alternative embodiment, the interrupt latency of the microcontroller is too large and the control element 10 can not be switched fast enough. In this case, the control is preferably already switched on reaching the first stop bit.

In Verbindung mit der schematischen Schnittdarstellung der Figur 3 ist eine Leuchte mit einer hier beschriebenen Steuervorrichtung 100 näher beschrieben. Die Leuchte umfasst beispielsweise einen Anschlussträger 31. Bei dem Anschlussträger 31 handelt es sich beispielsweise um eine Leiterplatte wie etwa eine bedruckte Leiterplatte, eine flexible bedruckte Leiterplatte oder eine Metallkernplatine. In und/oder auf den Anschlussträger 31 sind nicht gezeigte Anschlussstellen und Leiterbahnen strukturiert, mit denen auf dem Anschlussträger 31 angeordnete Komponenten kontaktiert und elektrisch leitend verbunden werden können. Vorliegend ist die Steuervorrichtung 100 an einer Unterseite des Anschlussträgers 31 angeordnet. An der der Unterseite abgewandten Oberseite sind Leuchtdiodenchips 30 angeordnet, die beispielsweise auch gruppenweise zu Leuchtdioden mit beispielsweise einem roten, einem blauen und zwei grünen Leuchtdiodenchips zusammengefasst sein können. Die Steuervorrichtung filtert aus dem Eingangssignal 21 die zum Betreiben der Leuchtdiodenchips 31 notwendige Information - also das Steuersignal 23 - heraus.In conjunction with the schematic sectional view of FIG. 3 a lamp with a control device 100 described here is described in more detail. The luminaire comprises, for example, a connection carrier 31. The connection carrier 31 is, for example, a printed circuit board such as a printed circuit board, a flexible printed circuit board or a metal core board. In and / or on the connection carrier 31, connection points and interconnects, not shown, are structured, with which components arranged on the connection carrier 31 can be contacted and electrically conductively connected. In the present case, the control device 100 is arranged on an underside of the connection carrier 31. On the upper side facing away from the bottom LED chips 30 are arranged, which may be summarized, for example, in groups to light emitting diodes with, for example, a red, a blue and two green LED chips. The control device filters out of the input signal 21 the information necessary for operating the light-emitting diode chips 31 - ie the control signal 23 - out.
