Abstract

The dynamo (1) has a magnetic field generator (2) for producing a magnetic field for wireless transmission of energy to an energy receiver (5) formed in a headlight (3) or taillight (4). The magnetic field generator is provided with a resonant circuit that has a capacitance, an electrical resistance and an inductance. The resonant circuit is provided with a variable resonant frequency. Independent claims are also included for the following: (1) a method for operating a lighting unit (2) a light, particularly head light or taillight with an energy receiver.

Description

Gegenstand dieser Erfindung ist eine Lichtanlage für Fahrzeuge, insbesondere für Fahrräder, die aus einem Generator, z. B. einem Fahrraddynamo, und zumindest einer Leuchte, z. B. einem Scheinwerfer oder/und einem Rücklicht besteht.object This invention is a lighting system for vehicles, especially for bicycles, the from a generator, eg. B. a bicycle dynamo, and at least one Light, z. B. a headlight and / or a taillight consists.

Lichtanlagen dieser Art sind bekannt und Stand der Technik. Bei solchen Lichtanlagen wird der vom Dynamo erzeugt Strom üblicherweise über eine Einfach- oder Doppelverkabelung zu den Beleuchtungskomponenten, den Verbrauchen, z. B. dem Scheinwerfer und/oder dem Rücklicht geführt.lighting systems This type are known and state of the art. In such lighting systems The power generated by the dynamo is usually or double cabling to the lighting components, consuming, z. B. the headlight and / or the tail light out.

Fahrräder werden immer filigraner, Zubehör wie z. B. Kabel wird häufig auch aus optischen Gründen in den Rahmen integriert. Ein weiterer Grund für die Verlegung von Kabeln im Rahmen ist die Gefahr von Beschädigung der freiliegenden Kabel. Durch die Integration in den Rahmen wird dieses Risiko zwar weitgehend minimiert, aber nicht sicher ausgeschlossen.Bicycles become always filigree, accessories like z. B. Cable becomes common also for optical reasons integrated into the frame. Another reason for laying cables in the frame is the risk of damage to the exposed cable. The integration into the framework, this risk is largely minimized, but not sure excluded.

Je nachdem, was für ein Dynamo und an welcher Stelle am Fahrrad verwendet wird, ist eine der beiden Beleuchtungskomponenten aufgrund der langen Verkabelung stärker von einem Kabelbruch gefährdet, und es kann zu einem Ausfall der Beleuchtungskomponente kommen. Beim derzeitigen Trend zum Nabendynamo ist das Rücklicht stärker gefährdet als der Scheinwerfer.ever after, what for a dynamo and where on the bike is used is one of the two lighting components due to the long wiring stronger endangered by a cable break, and there may be a failure of the lighting component. With the current trend towards the hub dynamo, the tail light is more endangered than the headlight.

Da auch das Verlegen der Kabel sehr aufwändig ist, gleichgültig ob diese in den Rahmen integriert werden oder freiliegend sind, ist es Aufgabe der vorliegenden Erfindung, den vom Dynamo erzeugten Strom ohne die Verwendung von Kabeln an die entsprechenden Fahrradkomponenten weiterzuleiten.There The laying of the cable is very complex, regardless of whether these are integrated into the frame or are exposed It is an object of the present invention, the current generated by the dynamo without the use of cables to the appropriate bicycle components forward.

Diese Aufgabe wird erfindungsgemäß durch eine drahtlose Energieübertragung realisiert, bei der im oder mit dem Dynamo verbunden ein Energiesender vorhanden ist, der ein Magnetfeld bestimmter Frequenz erzeugt und mit dem Energieempfänger, der in oder an dem Rücklicht und/oder dem Scheinwerfer integriert oder angebaut ist, korrespondiert und diesen in eine Resonanzschwingung versetzt. Diese Schwingungen können in elektrische Energie umgewandelt werden.These The object is achieved by a wireless energy transfer realized at the connected in or with the dynamo an energy transmitter is present, which generates a magnetic field of certain frequency and with the energy receiver, the in or on the tail light and / or the headlamp is integrated or attached, corresponds and this set in a resonant vibration. These vibrations can be in electrical energy to be converted.

Im Folgenden wird die erfindungsgemäße Vorrichtung anhand der beigefügten Figur näher erläutert, ohne auf die dort offenbarten Details und Ausführungsbeispiele beschränkt zu sein.in the The following will be the device according to the invention with the attached Figure closer explains without being limited to the details and embodiments disclosed therein.
