Abstract

The installation for supplying toys with electrical energy, preferably for production of light, comprises a sender of electromagnetic waves which is located at a small distance above a play area with the toys provided with appropriate receiver antennas and electronic energy conversion circuits.

Description

Die Erfindung betrifft eine Anlage zur drahtlosen Versorgung von Spielzeugen mit elektrischer Energie, die mit Hilfe eines Senders elektromagnetische Wellen überträgt, die von einem Empfänger mit einer Antenne empfangen wird, und die eine Lichtquelle zum Leuchten bringt. The invention relates to a system for the wireless supply of toys with electrical energy, which transmits by means of a transmitter electromagnetic wave that is received by a receiver with an antenna, and which brings a light source for lighting. Wich tig bei dieser Art der Versorgung ist, dass die Spielzeuge selbst keine eigene Stromversorgung, wie Batterien, Akkumulatoren o. ä., benötigen, und dass die Versorgung ortsunabhängig erfolgt. what is most important in this type of care that the toys themselves do not own power supply, such as batteries, accumulators o. ä., need, and that the supply is independent of location. Eine weitere wesentliche Besonderheit dieser Versorgungsart ist die einfache Erzeugung des Sendesignals durch einen Funktionsgenerator mit einer einstellbaren Frequenz. Another essential feature of this type of supply is the simple generation of the transmission signal by a function generator having an adjustable frequency. Der Antennen eingang des Empfängers ist auf die vorgegebene Frequenz optimiert. The antenna input of the receiver is optimized for the predetermined frequency.

Die drahtlose Energieübertragung mittels eines Wechselfeldes ist grundsätzlich aus EP-B1-91-971 bekannt. The wireless power transmission by means of an alternating field is basically known from EP-B1-91-971. Bei einer derartigen Anlage wird das Magnetfeld in parallel zu einer Fahrstrecke geführten Stableitern erzeugt, wodurch Fahrspielzeuge geleitet werden können. In such a system, the magnetic field is generated in parallel to a guided route rod conductors, which toy vehicles can be conducted.

Es wird ein weiteres Verfahren beschrieben, in dem "Steuersignale" über ein Sen der/Empfänger-System übertragen werden (DE 39 03 535 A1). There will be described another method, in the "control signals" a Sen / receiver system are transmitted (DE 39 03 535 A1). Diese Steuersignale werden über eine Luftspule als Sender und einer Empfängerspule auf das Spielzeug übertragen, dann aber mit relativ aufwendigen Mitteln (Bandfilter, Mikroprozessor, Signalformer usw.) für die Steuerung des Spielzeuges genutzt. These control signals are transmitted via an air coil as a transmitter and a receiver coil on the toy, but then with relatively expensive means (band filters, microprocessors, signal conditioners, etc.) used to control the toy. Die Spielzeuge ihrerseits werden mit externen Span nungsquellen betrieben. The toys themselves are equipped with external clamping voltage sources.

Ein weiteres Verfahren der drahtlosen Energieübertragung mittels induzierter Spannungen wird in der Patentanmeldung 100 24 648.6 beschrieben. Another method of wireless energy transmission by means of induced voltages is described in the patent application 100 24 648.6.

Alle diese Verfahren nutzen für die Übertragung von Energie oder Informationen das Prinzip der Induktion. All of these methods use the principle of induction for the transfer of energy or information.

Der Erfindung liegt daher die Aufgabe zugrunde, in einem abgegrenzten Spielbereich, der Mo dellfläche, mit Hilfe eines in der räumlichen Nähe (im Meter-Bereich) des Spielbereiches ange ordneten Senders über eine Sendeantenne Energie zu den in einem Spielzeug integrierten elektrischen Verbraucher zu übertragen. The invention is therefore based on the object within a defined play area, the dell surface Mo, by means of a in the proximity arranged (in the meter range) of the playing area transmitter via a transmission antenna to transmit power to the built-in toy electric consumer. Die Spielzeuge brauchen dabei nicht über eigene Spannungsquellen zu verfügen. The toys need not to have their own power sources. Die Energie wird vorzugsweise für die Beleuchtung der Spiel zeuge genutzt. The energy is used preferably tools for lighting the match.

B. low-current LEDs (light emitting diodes) are only needs about 2 mW for the operation of an LED. Bei einer erzielten Spannung von nur ca. 2 V kann eine low-current-LED schon mit einem Strom von 1 mA betrieben werden. Obtained at a voltage of only about 2 V is a low-current-LED can already be operated at a current of 1 mA. Wenn es sich um eine rote LED handelt, kann diese Licht z. If there is a red LED, this light can z. B. in einem Miniaturauto als Rücklicht genutzt werden. B. be used in a miniature car as a taillight. Das Licht kann mit einem passiven Lichtleiter (z. B. bestehend aus Acrylglas) an jeden gewünschten Ort gelenkt werden. The light may be directed to a passive optical waveguide (z. B. consisting of acrylic glass) to any desired location.

Zur Lösung dieser Aufgabe werden die mit Anspruch 1-11 gekennzeichneten Merkmale und Maßnahmen vorgeschlagen. To achieve this object, the features and measures marked with claim 1-11 are proposed.
