Abstract

In order to obtain optic indications and/or infrared transmissions having the best possible omnidirectional characteristics in mobile radio transmitting sets, a helix antenna (HA) is used, which is coiled round in an optical guide (LL). This optical guide has a rounded end piece (ES).

Description

Beschreibungdescription
HelixantenneHelix antenna
Bei Mobilfunkendgeräten Infrarotsender/-empfänger für Zwecke der Datenübertragung oder zur Fernbedienung oder zur Anbin- dung eines Kopfhörers bzw. einer Freisprecheinrichtung verwendet werden. Andererseits kommen auch Leuchtdioden im sichtbaren Spektralbereich als Indikatoren zum Einsatz, z.B. um den Benutzer darauf aufmerksam zu machen, daß das Mobilfunkgerät in das Netz eines Betreibers eingebucht ist .In the case of mobile radio terminals, infrared transmitters / receivers are used for the purpose of data transmission or for remote control or for connecting headphones or a hands-free device. On the other hand, light-emitting diodes in the visible spectral range are also used as indicators, e.g. to draw the user's attention to the fact that the mobile radio device is logged into the network of an operator.
Bei allen diesen Anwendungen ist eine Licht- oder Infrarotab- strahlung mit möglichst ausgeprägter Rundstrahlcharakteristik wünschenswert. Der vorliegenden Erfindung liegt also die Aufgabe zugrunde, eine entsprechende Vorrichtung anzugeben, die für Mobiltelefone möglichst gut geeignet ist. Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst. Bei dieser Vorrichtung wird eine Helixantenne verwendet, die im ei- nen Lichtleiter gewickelt ist. Dieser Lichtleiter hat ein gewölbtes Endstück.In all of these applications, light or infrared radiation with the most pronounced omnidirectional characteristic is desirable. The present invention is therefore based on the object of specifying a corresponding device which is as suitable as possible for mobile telephones. This object is achieved by a device according to claim 1. In this device, a helical antenna is used, which is wound in an optical fiber. This light guide has a curved end piece.
Figur 1 zeigt in schematischer Weise eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung.Figure 1 shows schematically a preferred embodiment of the device according to the invention.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.
Im folgenden wird die Erfindung anhand der Figur und mit Hilfe bevorzugter Ausführungsbeispiele näher beschrieben. Bei dieser Vorrichtung ist eine Helixantenne um (HA) , die um einen wenigstens teilweise zylindrischen Lichtleiter (LL) gewickelt ist, der an ein gewölbtes Endstück (ES) grenzt, welches Licht mit einer Rundstrahlcharakteristik abstrahlt.The invention is described in more detail below with reference to the figure and with the aid of preferred exemplary embodiments. In this device, a helical antenna is around (HA), which is wound around an at least partially cylindrical light guide (LL), which borders on a curved end piece (ES), which emits light with an omnidirectional characteristic.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird ein Lichtleiter verwendet, der an seinem anderen Ende in einem Befestigungssockel (BS) steckt. Dieses Ende des Lichtleiters dient auch zum Einkoppeln der von einer Leuchtdiode (LED) ausgestrahlten Licht- oder Infrarotstrahlen.According to a preferred embodiment of the invention, an optical fiber is used, which is inserted at its other end in a mounting base (BS). This end of the light guide also serves to couple in the light or infrared rays emitted by a light emitting diode (LED).
Um das Licht oder die Infrarotstrahlen möglichst verlustfrei in das gewölbte Endstück (ES) zu leiten, ist eine Ausführungsvariante besonders vorteilhaft, bei welcher der Licht- leiter wenigstens teilweise von einer lichtundurchlässigen Ummantelung (M) umgeben ist . In order to guide the light or the infrared rays into the curved end piece (ES) with as little loss as possible, an embodiment variant is particularly advantageous in which the light guide is at least partially surrounded by an opaque sheath (M).
