Besonders bevorzugt umfasst die Anpassvorrichtung jedoch die Serienschaltung eines ersten ohmschen Widerstands und einer ersten Diode, insbesondere Schottky-Diode, und die Serienschaltung eines zweiten ohmschen Widerstands und einer zweiten Diode, insbesondere Schottky-Diode, die zur Serienschaltung des ersten ohmschen Widerstands und der ersten Diode antiparallel geschaltet ist. Diese Realisierung berücksichtigt, dass unterschiedliche Signalisierungsleuchtmittel mit unterschiedlichen Spannungen zu betreiben sind, um eine optimale Ansteuerung sicherzustellen. Werden beispielsweise für die Signalisierungsleuchtmittel LEDs verwendet, so ist der bevorzugte Widerstandswert für eine LED, die im roten Wellenlängenbereich abstrahlt, ein anderer als für eine LED, die im grünen oder im blauen Wellenlängenbereich abstrahlt. Durch die soeben vorgestellte bevorzugte Ausführungsform lässt sich diesen Randbedingungen in optimaler Weise Rechnung tragen. Demnach ist es bevorzugt, wenn der erste ohmsche Widerstand einen anderen Widerstandswert aufweist als der zweite ohmsche Widerstand.Preferably, the matching device comprises at least one ohmic resistance. However, the adaptation device particularly preferably comprises the series connection of a first ohmic resistor and a first diode, in particular a Schottky diode, and the series connection of a second ohmic resistor and a second diode, in particular a Schottky diode, for the series connection of the first ohmic resistor and the first diode is connected in anti-parallel. This realization takes account of the fact that different signaling illuminants are to be operated with different voltages in order to ensure optimum control. For example, when LEDs are used for the signaling illuminants, the preferred resistance for an LED that emits in the red wavelength range is different than for an LED that emits in the green or blue wavelength range. By the preferred embodiment just presented, these boundary conditions can be optimally taken into account. Accordingly, it is preferable if the first ohmic resistance has a different resistance value than the second ohmic resistance.
Dadurch wird das Mittelpunktpotential asymmetrisch gestaltet, was insbesondere den Betrieb verbessert, wenn eines der Signalisierungsleuchtmittel eine blaue LED darstellt.As a result, the midpoint potential is made asymmetrical, which in particular improves the operation when one of the signaling illuminants represents a blue LED.
Bei einer besonders bevorzugten Ausführungsform weist die Signalisierungsvorrichtung einen Anschluss zum Koppeln mit einer Gleichspannungsquelle auf, wobei die Signalisierungsvorrichtung weiterhin einen Spannungsregler umfasst, dessen Eingang mit dem Anschluss zum Koppeln mit einer Gleichspannungsquelle gekoppelt ist, wobei der Spannungsregler ausgelegt ist, an seinem Ausgang eine Spannung bereitzustellen, die kleiner ist als die an seinem Eingang anliegende Spannung. Dies eröffnet die Möglichkeit, einerseits für zumindest eines der Signalisierungsleuchtmittel die höhere Spannung, die am Anschluss zum Koppeln mit einer Gleichspannungsquelle anliegt, zur Verfügung zu stellen, während die Spannung am Ausgang des Spannungsreglers einer entsprechend ausgelegten Steuervorrichtung zur Verfügung gestellt wird. Je niedriger nämlich die Spannung, auf die die Steuervorrichtung ausgelegt ist, umso verlustärmer kann diese betrieben werden. Diese Konstellation trägt weiterhin dem Umstand Rechnung, dass unterhalb eines bestimmten Spannungswerts eine Serienschaltung zweier Signalisierungsleuchtmittel, insbesondere LEDs, nicht mehr möglich ist, während jedoch Steuervorrichtungen am Markt erhältlich sind, die auf einem derartig niedrigen Spannungsniveau noch arbeiten können. In konkreten Zahlenwerten kann beispielsweise an den Anschluss zum Koppeln mit einer Gleichspannungsquelle eine Gleichspannungsquelle mit einer Spannung von 5 V bis 6 V angelegt werden, während die Spannung am Ausgang des Spannungsreglers, die zur Versorgung der Steuervorrichtung verwendet wird, beispielsweise 3,3 V oder sogar noch weniger betragen kann.In a particularly preferred embodiment, the signaling device has a terminal for coupling to a DC voltage source, the signaling device further comprising a voltage regulator whose input is coupled to the terminal for coupling to a DC voltage source, the voltage regulator being adapted to provide a voltage at its output , which is smaller than the voltage applied to its input. This makes it possible on the one hand for at least one of the signaling illuminants to provide the higher voltage which is present at the connection for coupling to a DC voltage source, while the voltage at the output of the voltage regulator is made available to a correspondingly designed control device. Namely, the lower the voltage to which the control device is designed, the less lossy it can be operated. This constellation also takes into account the fact that below a certain voltage value, a series connection of two signaling illuminants, in particular LEDs, is no longer possible, while, however, control devices are available on the market which can still operate at such a low voltage level. In concrete numerical values, for example, to the terminal for coupling with a DC voltage source, a DC voltage source with a voltage of 5 V to 6 V are applied, while the voltage at the output of Voltage regulator, which is used to power the control device, for example, 3.3 V or even less.
Eine Ausführungsform, die von dieser vorteilhaften Gestaltung Gebrauch macht, umfasst einen elektronischen Schalter mit einer Steuerelektrode, einer Arbeitselektrode und einer Bezugselektrode, wobei die Steuervorrichtung mit dem Ausgang des Spannungsreglers gekoppelt ist, wobei das erste Signalisierungsleuchtmittel zwischen den Anschluss zum Koppeln mit einer Gleichspannungsquelle und die Arbeitselektrode des elektronischen Schalters gekoppelt ist, wobei der erste der drei Anschlüsse der Steuervorrichtung mit der Steuerelektrode des elektronischen Schalters gekoppelt ist, wobei das zweite Signalisierungsleuchtmittel zwischen den zweiten der drei Anschlüsse der Steuervorrichtung und die Bezugselektrode des elektronischen Schalters gekoppelt ist, wobei die Bezugselektrode des elektronischen Schalters über die Anpassschaltung mit dem dritten der drei Anschlüsse der Steuervorrichtung gekoppelt ist.An embodiment making use of this advantageous embodiment comprises an electronic switch having a control electrode, a working electrode and a reference electrode, the control device being coupled to the output of the voltage regulator, the first signaling illuminant interposing between the terminal for coupling to a DC voltage source and the Working electrode of the electronic switch is coupled, wherein the first of the three terminals of the control device is coupled to the control electrode of the electronic switch, wherein the second signaling illuminant between the second of the three terminals of the control device and the reference electrode of the electronic switch is coupled, wherein the reference electrode of the electronic Switch is coupled via the matching circuit with the third of the three terminals of the control device.
Bei einer weiteren besonders bevorzugten Ausführungsform der vorliegenden Erfindung umfasst die Steuervorrichtung einen Mikrocontroller und eine Treibervorrichtung, wobei der Mikrocontroller über eine erste und eine zweite Steuerleitung mit der Treibervorrichtung gekoppelt ist, wobei die Treibervorrichtung den ersten, den zweiten und den dritten Anschluss aufweist. Dabei ist der Mikrocontroller bevorzugt ausgelegt, über die erste und die zweite Steuerleitung Schaltsignale zum Einschalten des ersten oder des zweiten oder des ersten und des zweiten Signalisierungsleuchtmittels an die Treibervorrichtung anzulegen.In another particularly preferred embodiment of the present invention, the controller includes a microcontroller and a driver device, wherein the microcontroller is coupled to the driver device via first and second control lines, the driver device having the first, second, and third ports. In this case, the microcontroller is preferably designed to apply switching signals for switching on the first or the second or the first and the second signaling illumination means to the driver device via the first and the second control line.
Diese Konstellation eröffnet nun die Möglichkeit, den Mikrocontroller mit dem Ausgang des Spannungsreglers zu koppeln und die Treibervorrichtung mit dem Anschluss zum Koppeln mit einer Gleichspannungsquelle. Dadurch, dass auf diese Weise der Mikrocontroller mit einer niedrigen Versorgungsspannung betrieben wird, kann zum einen eine Stromersparnis erzielt werden, zum anderen steht über die Treibervorrichtung eine genügend hohe Spannung zur Verfügung, um die beiden Signalisierungsleuchtmittel im dritten Zustand in Serie zu betreiben.This constellation now provides the ability to couple the microcontroller to the output of the voltage regulator and the driver device to the connector for coupling to a DC voltage source. The fact that in this way the microcontroller is operated with a low supply voltage, on the one hand, a power savings can be achieved, on the other hand is about the driver device, a sufficiently high voltage available to operate the two signaling illuminants in the third state in series.
Generell ist das erste Signalisierungsleuchtmittel ausgelegt, eine Strahlung in einem ersten sichtbaren Wellenlängenbereich abzugeben, und das zweite Signalisierungsleuchtmittel ist ausgelegt, eine Strahlung in einem zweiten sichtbaren Wellenlängenbereich abzugeben, der vom ersten sichtbaren Wellenlängenbereich verschieden ist. Bei den Wellenlängenbereichen kann es sich insbesondere um den roten, den grünen und den blauen Wellenlängenbereich handeln.In general, the first signaling illuminant is configured to emit radiation in a first visible wavelength range, and the second signaling illuminant is configured to emit radiation in a second visible wavelength range that is different from the first visible wavelength range. The wavelength ranges may be, in particular, the red, the green and the blue wavelength range.
Wie bereits erwähnt, stellt das erste und das zweite Signalisierungsleuchtmittel jeweils mindestens eine LED dar. In diesem Zusammenhang kann vorgesehen sein, dass seriell zum ersten Signalisierungsleuchtmittel ein erster ohmscher Widerstand und seriell zum zweiten Signalisierungsleuchtmittel ein zweiter ohmscher Widerstand gekoppelt ist.As already mentioned, the first and the second signaling illuminant each represent at least one LED. In this connection it can be provided that a first ohmic resistance is serially coupled to the first signaling illuminant and a second ohmic resistance is serially coupled to the second signaling illuminant.
Wie ebenfalls bereits erwähnt, weist die Steuervorrichtung bevorzugt mindestens einen Ausgang zum Ansteuern einer übergeordneten Zentralsteuervorrichtung in Abhängigkeit des Signals an dem mindestens einen Informationseingang auf.As also already mentioned, the control device preferably has at least one output for activating a superordinate central control device in dependence the signal at the at least one information input.

Seriell zur LED1 ist ein Schalter S5 gekoppelt, dessen Basis über einen Basiswiderstand Rb1 mit dem Anschluss PB1 der Steuervorrichtung 12 gekoppelt ist. Die Arbeitselektrode des Schalters S5 ist mit der Serienschaltung aus der LED1 und dem ohmschen Widerstand Rv1 gekoppelt. Die Bezugselektrode des Schalters S5 ist mit dem Kopplungspunkt K gekoppelt, wobei eine Anpassvorrichtung 16 zwischen den Kopplungspunkt K und den Anschluss PB0 der Steuervorrichtung 12 gekoppelt ist, die die Serienschaltung eines ohmschen Widerstands Rv0L und einer ersten Schottky-Diode D1 umfasst, sowie die Serienschaltung eines zweiten ohmschen Widerstands Rv0H und einer zweiten Schottky-Diode D2, die zur Serienschaltung des ersten ohmschen Widerstands Rv0L und der ersten Schottky-Diode D1 antiparallel geschaltet ist. Dies Maßnahme trägt dem Umstand Rechnung, dass, um den Transistor S5 schalten zu können, die Spannung VCC mindestens um die Basis-Emitter-Spannung höher liegen muss als die Spannung am Kopplungspunkt K. Durch eine derartige Ausbildung der Anpassvorrichtung 16 lässt sich die verfügbare Restspannung optimal ausnutzen, wobei die Widerstandswerte Rv0L und Rv0H nicht zu klein werden dürfen, da sich ansonsten Toleranzen verstärkt auswirken würden. Durch diese Maßnahme lässt sich insbesondere die unterschiedliche Flussspannung unterschiedlicher LEDs, insbesondere LEDs, die sich im Hinblick auf den Wellenlängenbereich des von ihnen abgestrahlten Lichts unterscheiden, berücksichtigen.A switch S5 is coupled in series with the LED1, the base of which is coupled to the terminal PB1 of the
Bei alleinigem Betrieb der LED1 fließt demnach ein Strom von V0 durch Rv1, LED1, S5, Rv0L, D1 zum Anschluss PB0, während bei alleinigem Betrieb der LED2 ein Strom von PB0 über D2, den ohmschen Widerstand Rv0H, die LED2 und den ohmschen Widerstand Rv2 zurück zum Anschluss PB2 fließt. Werden beide LEDs gleichzeitig betrieben, fließt ein Strom von V0 über Rv1, die LED1, den Schalter S5, die LED2, den ohmschen Widerstand Rv2 zum Anschluss PB2 der Steuervorrichtung 12.When the LED1 is operated alone, a current flows from V0 through Rv1, LED1, S5, Rv0L, D1 to the terminal PB0, while when the LED2 alone is operated, a current flows from PB0 via D2, the ohmic resistance Rv0H, the LED2 and the ohmic resistance Rv2 back to port PB2 flows. If both LEDs are operated simultaneously, a current flows from V0 via Rv1, the LED1, the switch S5, the LED2, the ohmic resistance Rv2 to the terminal PB2 of the
Bei dieser Ausführungsform kann der Mikrocontroller 17 mit der niedrigen Versorgungsspannung VCC betrieben werden, was in einer Stromersparnis resultiert. Für die Reihenschaltung der beiden LEDs in dem Betriebszustand, in dem beide LEDs einzuschalten sind, steht über die Kopplung des Treiberbausteins 18 mit dem Anschluss für eine Gleichspannungsquelle V0 genug Spannung zur Verfügung, so dass insbesondere auch blaue LEDs in einer derartigen Anordnung betreibbar sind.In this embodiment, the
