Abstract

A prim. coil body produces a magnetic field which attracts the light bulb. The magnetic alternating is produced by the lamp frame and the core of the prim. coil body should not be closed, and can be part of the frame. Different types of lamps can be used, e.g. with HF magnetic field for fluorescent lamps. With the use of a light bulb or LED, this must be connected to a sec. coil. The sec. coil transforms the magnetic alternating field to an AC voltage, which is used to operate the bulb or LED. A regulating circuit is provided with a sensor, e.g. for measuring distance between suspended object and magnet. USE/ADVANTAGE - E.g. reflection light barrier. Lamp and sec. coil have no mechanical contact to remaining construction.

Description

1. Der primäre Spulenkörper1. The primary bobbin

Der primäre Spulenkörper hat zwei Aufgaben:
1.) Er liefert das Magnetfeld, daß die Glühlampe anzieht.
2.) Er erzeugt das magnetische Wechselfeld, das zur drahtlosen Energieübertragung benötigt wird.The primary bobbin has two functions:
1.) It provides the magnetic field that attracts the light bulb.
2.) It generates the alternating magnetic field that is required for wireless energy transmission.

Der Kern des primären Spulenkörpers darf nicht geschlossen sein, so daß das Magnetfeld sich nach unten ausbreiten kann.The core of the primary bobbin must not be closed so that the magnetic field after can spread out below.

Der Kern kann auch ein Teil des Gestells sein, was den Wirkungsgrad erhöht.The core can also be part of the frame, which increases efficiency.

2. Die Aufhängung/Form des Gestells2. The suspension / shape of the frame

Um zu gewährleisten, daß sich das Magnetfeld so geradlinig wie möglich ist müssen die Aufhängung und das Gestell aus Metall sein und die Form eines "C" haben (siehe Skizze).To ensure that the magnetic field so is as straight as possible the suspension and the frame be made of metal and the Have the shape of a "C" (see sketch).

Die Primärspule wird am oberen Ende angebracht. Dadurch wird das Magnetfeld zwischen den Enden so geradlinig wie möglich und ein Abwandern des schwebenden Objekts verhindert.The primary coil is at the top appropriate. This will create the magnetic field between the ends as straight as possible and one Prevents the floating object from migrating.

3. Messung des Abstandes3. Measure the distance

Der Sensor des Regelschaltkreises kann auf verschiedene Arten realisiert werden.The sensor of the control circuit can be on different types can be realized.

Die einfachste Möglichkeit besteht darin, eine Lichtschranke (z. B. Infrarot) zu nehmen, die den Abstand zwischen dem schwebenden Objekt und dem Magneten mißt.The easiest way is to get one To take light barrier (e.g. infrared) the distance between the floating object and the magnet.

Da sich auch die Impedanz der Primärspule durch Annäherung des schwebenden Objektes ändert, kann diese Veränderung auch zur Bestimmung des Abstandes verwendet werden.Because the impedance of the primary coil also changes Approach of the floating object can change this change also to determine the distance be used.

Das Meßergebnis wird an den Regelschaltkreis weitergeleitet. The measurement result is sent to the control circuit forwarded.  

4. Der Regelschaltkreis4. The control circuit

Der Regelschaltkreis erhält seine Daten von dem Sensor. Er erzeugt eine Wechselspannung, die er an die Primärspule abgibt. Die Frequenz der Spannung muß auf die Sekundärspule abgestimmt sein. Die Spannung sinkt, wenn das schwebende Objekt zu stark angezogen wird, und steigt an, wenn es herabzufallen droht.The control circuit receives its data from that Sensor. It generates an AC voltage which it to the primary coil. The frequency of the Voltage must be matched to the secondary coil. The tension drops when the floating object is over-tightened and rises when it is threatens to fall.

Es wird immer eine Mindestspannung bereitgestellt. Die Höhe der Mindestspannung hängt von dem Gewicht und dem Abstand des schwebenden Objektes von der Primärspule ab.A minimum voltage is always provided. The level of the minimum tension depends on the weight and the distance of the floating object from the Primary coil.

5. Die Lampe/Die Sekundärspule5. The lamp / secondary coil

Es können verschiedene Lampenarten verwendet werden. Für eine Leuchtstofflampe muß das Magnetfeld hochfrequent sein, um die Leuchtstoff­ lampe direkt zum Leuchten anzuregen!Different types of lamps can be used. For a fluorescent lamp that has to Magnetic field to be high frequency to the phosphor to stimulate the lamp directly to light up!

Wenn eine Glühlampe oder LED benutzt wird, muß diese mit einer Sekundärspule verbunden sein. Die Sekundärspule wandelt das magnetische Wechselfeld in eine Wechselspannung um, die zum Betrieb der Glühlampe (LED u. a.) benützt wird. Die Form der schwebenden Lampe sollte zylindrisch sein. Die Glühlampe sollte im unteren Teil und die Sekundärspule im oberen Teil des Zylinders liegen.If a light bulb or LED used with a secondary coil be connected. The secondary coil is changing the alternating magnetic field into an alternating voltage um, which is used to operate the light bulb (LED, etc.). The shape of the floating lamp should be cylindrical. The light bulb should be in the lower part and the secondary coil in the upper part Part of the cylinder.

Der obere Teil muß ferromagnetisch sein. Die Wicklung der Sekundärspule kann aus lackiertem Eisendraht sein, um die Wirkung des Elektromagneten zu verstärken.The upper part must be ferromagnetic. The winding The secondary coil can be made of painted iron wire to increase the effect of the electromagnet.
