Description
Für Fahrzeugleuchten ist der Einsatz von Leuchtdioden an sich bekannt. Insbesondere bei Anhänger-Beleuchtungsanordnungen, welche über eine mehrpolige Steckverbindung aus dem Bordnetz eines Zugfahrzeugs gespeist sind, kann die Bordnetzspannung erhebliche Schwankungen gegenüber der Bordnetz-Nennspannung aufweisen. Bekannt ist hierzu auch, durch getaktete Wandlereinrichtungen solche Schwankungen auszuregeln und über einen weiten Bereich der am Eingang der Wandlereinrichtungen anliegenden schwankenden Bordnetzspannung eine gleichmäßige Leuchtstärke der Leuchtdioden zu gewährleisten.For vehicle lights is the use of light-emitting diodes known per se. Especially at Trailer lighting arrangements, which about one multi-pin connector fed from the electrical system of a towing vehicle are, the vehicle electrical system voltage can vary considerably from the Wiring Voltage exhibit. This is also known, by clocked converter devices such Balance fluctuations and over a wide range of the voltage applied to the input of the converter devices fluctuating on-board voltage a uniform luminosity of To ensure light-emitting diodes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine LED-Fahrzeugleuchte mit erweiterten Einsatzmöglichkeiten und eine Anhänger-Beleuchtungsanordnung mit solchen Fahrzeugleuchten anzugeben.Of the present invention has for its object to provide an LED vehicle lamp with extended application possibilities and a trailer lighting assembly indicate with such vehicle lights.
Erfindungsgemäße Lösungen sind in den unabhängigen Ansprüchen beschrieben. Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen.Inventive solutions are in the independent ones claims described. The dependent ones claims contain advantageous embodiments and developments.
Durch Auslegen der Leuchte sowohl für Bordnetze mit einer ersten niedrigeren Nennspannung als auch für Bordnetze mit einer zweiten höheren Nennspannung, insbesondere für 12 Volt und 24 Volt Nennspannung, und Bemessung des Eingangsspannungsbereichs der getakteten Wandleranordnung, innerhalb welcher diese eine im wesentlichen gleichmäßige Leistungsaufnahme bzw. Leuchtstärke der Leuchtdioden gewährleistet, in der Art, dass eine untere Bereichsgrenze des Eingangsspannungsbereichs unter der ersten niedrigeren Nennspannung, z. B. 12 Volt, und eine obere Bereichsgrenze über der zweiten oberen Nennspannung, z. B. 24 Volt liegt, werden trotz erhöhter Anforderungen an die Wandlereinrichtung sowohl wirtschaftliche Vorteile als auch Gebrauchsvorteile erzielt.By Layout of the luminaire for both on-board systems with a first lower rated voltage as well as for electrical systems with a second higher Rated voltage, especially for 12 volt and 24 volt rated voltage, and rated input voltage range the clocked transducer assembly, within which this one in substantially uniform power consumption or luminosity of Ensures light-emitting diodes in the way that a lower range limit of the input voltage range below the first lower rated voltage, e.g. B. 12 volts, and a upper range limit over the second upper rated voltage, z. B. 24 volts is, despite increased Requirements for the converter device both economic benefits as well as use advantages achieved.
Vorteilhafterweise liegt die untere Bereichsgrenze um wenigstens 25% der ersten niedrigen Bordnetz-Nennspannung, insbesondere bei höchstens 9 Volt.advantageously, is the lower range limit at least 25% of the first low nominal voltage of the electrical system, especially at most 9 volts.
Vorteilhafterweise liegt die obere Bereichsgrenze um wenigstens 25%, vorzugsweise wenigstens 40% über der zweiten oberen Nennspannung, insbesondere bei wenigstens 30 Volt, vorzugsweise bei wenigstens 34 Volt.advantageously, the upper range limit is at least 25%, preferably at least 40% over the second upper rated voltage, in particular at least 30 Volts, preferably at least 34 volts.
Die Auslegung der Leuchte auf gleichzeitig zwei verschiedene Standard-Bordnetzspannungen von 12 Volt und 24 Volt führt zum einen zu einer verbesserten Wirtschaftlichkeit der Herstellung der Leuchten, welche als gesamte Leuchten oder zumindest in deren elektrischen und elektrooptischen Teilen dadurch für eine größere Zahl von Anwendungen und damit in größerer Stückzahl herstellbar sind. Für Leuchtenanordnungen in landwirtschaftlichen oder Nutzfahrzeug-Anhängern, welche aus den Bordnetzen von jeweiligen Zugfahrzeugen gespeist sind, ergibt sich der zusätzliche Vorteil, dass ein solcher Anhänger sowohl hinter einer landwirtschaftlichen Zugmaschine mit typischerweise 12 Volt Bordnetz-Nennspanung als auch hinter einer Nutzfahrzeug- Zugmaschine mit typischerweise 24 Volt Bordnetz-Nennspannung betrieben werden kann, ohne dass aufwendige Spannungs-Adaptereinrichtungen erforderlich sind.The Design of the luminaire on two different standard on-board voltages from 12 volts and 24 volts leads on the one hand to an improved economy of production the lights, which as entire lights or at least in their electrical and electro-optical parts thereby for a larger number of applications and thus in larger quantities to produce are. For luminaire arrangements in agricultural or commercial vehicle trailers, which from the on-board networks fed by respective towing vehicles, the additional results Advantage that such a trailer both behind an agricultural tractor with typically 12 volt board nominal voltage as well as behind a commercial vehicle tractor with typically 24 Volt board voltage can be operated without consuming Voltage adapter devices are required.
Vorteilhafterweise sind die getakteten Wandlereinrichtungen mit den Leuchtdioden jeweils auf einer gemeinsamen Schaltungsplatine angeordnet. Vorteilhafterweise sind die getakteten Wandlereinrichtungen, zu welchen auch die Steuerelektronik zur Ansteuerung der getakteten Schaltelemente solcher Wandlereinrichtungen gezählt seien, mit Überlast-Sicherungs-Einrichtungen, insbesondere zur Abschaltung der Wandlereinrichtungen, ausgestattet. Die Leuchten können auch vorteilhafterweise mit vorzugsweise selbstrückstellenden Überstromsicherungen nach Art von Polymersicherungen ausgerüstet sein.advantageously, are the clocked converter devices with the LEDs each arranged on a common circuit board. advantageously, are the clocked converter devices, which include the control electronics for controlling the clocked switching elements of such converter devices counted with overload protection devices, in particular for switching off the converter devices equipped. The lights can also advantageously with preferably self-resetting overcurrent fuses be equipped in the manner of polymer fuses.
Bei einer Beleuchtungsanordnung eines landwirtschaftlichen oder Nutzfahrzeug-Anhängers mit Leuchten der vorstehend beschriebenen Art und einer mehrpoligen Steckerverbindung zur Verbindung mit dem Nutzfahrzeug können vorteilhafterweise die beiden gemäß Vorschrift aus Sicherheitsgründen getrennt geführten Leitungen bzw. Pole mit den Bezeichnungen 58L und 58R zur Versorgung von Fahrlicht-Heckleuchten (Rücklichtern) und gemeinsam mit diesen umgeschalteten weiteren Leuchten wie Spurhalteleuchten, Seitenmarkierungsleuchten etc. vorteilhafterweise anhängerseitig unter Einfügung von Dioden als Rückwirkungssperren auf eine Leitung zusammengefasst werden, da durch die erfindungsgemäßen Leuchten die der Vorschrift zugrunde liegenden Überlegungen zu dem Fall, dass ein Kurzschluss einer Leuchte nicht zum Ausfall aller gemeinsam eingeschalteten Leuchten führen darf, nicht mehr gelten.at a lighting arrangement of an agricultural or commercial vehicle trailer with Lights of the type described above and a multi-pole Plug connection for connection to the commercial vehicle can advantageously the two according to regulation for safety reasons run separately Lines or poles with the designations 58L and 58R for supply of driving light rear lights (taillights) and together with these other switched lights such as lane lights, Side marker lights, etc. advantageously on the trailer side under insertion of diodes as retroactivity barriers be summarized on a line, as by the lights according to the invention the considerations underlying the provision on the case that a Short circuit of a lamp not to the failure of all switched on together Luminaires lead may no longer apply.
