Abstract

The aerial has the external appearance of a shaft and is provided with a light source. The aerial itself comprises a light guide (9) with a part on the surface of the light guide (9T) which is designed to diffuse the light. The light source (10) is mounted outside the aerial itself. The light guide may be formed in one piece, with the diffusing section formed by treatment of the surface of the light guide material - for example by un-polishing the surface. This guide is then surrounded by the conducting wire forming the aerial in the form of a helicoidal spring. An outer translucent envelope may then cover the complete assembly. The aerial is attached to a portable telephone and the light source controlled to produce flashes of light.

Description

Elle concerne également un émetteur-récepteur de radio-communication équipé d'une antenne.It also relates to a radio communication transceiver equipped of an antenna.

L'invention s'applique entre autres aux téléphones cellulaires.The invention applies inter alia to cellular telephones.

Une antenne munie d'une source de lumière est décrite par le document US 2,473,981 (Wood). L'antenne décrite par ce document comprend une ampoule à incandescence qui diffuse de la lumière dans un manchon transparent qui entoure le conducteur électrique métallique qui constitue l'antenne elle même.An antenna provided with a light source is described by the document US 2,473,981 (Wood). The antenna described by this document includes a light bulb. incandescence which diffuses light in a transparent sleeve which surrounds the metallic electrical conductor which constitutes the antenna itself.

Un objet de l'invention est d'améliorer à la fois l'efficacité de l'antenne, sa fiabilité, et son coût.An object of the invention is to improve both the efficiency of the antenna, its reliability, and its cost.

A cet effet, l'antenne elle même est constituée par une partie électrique de type hélicoïdal formée par un ressort métallique, et elle entoure au moins partiellement le conduit de lumière.For this purpose, the antenna itself is constituted by an electrical part of the type helical formed by a metal spring, and it at least partially surrounds the light pipe.

Ceci permet de transmettre la lumière au travers de la partie électrique de l'antenne, sans que cette dernière n'occulte la lumière.This allows light to be transmitted through the electrical part of the antenna, without the latter obscuring the light.

Dans une forme particulière de réalisation, la source de lumière produit de la lumière sous forme de flashes.In a particular embodiment, the light source produces light in the form of flashes.

Avantageusement, le conduit de lumière et la partie diffusant la lumière sont faits d'une seule pièce, la partie diffusant la lumière étant constituée par un traitement, qui rend la surface diffusante pour la lumière, et qui est appliqué à une partie de la surface du conduit.Advantageously, the light pipe and the light diffusing part are made in a single piece, the part diffusing the light being constituted by a treatment, which makes the surface diffusing for light, and which is applied to part of the surface of the duct.

De préférence, la partie diffusant la lumière est située près d'une l'extrémité de la tige.Preferably, the light diffusing part is located near one end of the rod.

Ainsi le signal lumineux est plus visible.Thus the light signal is more visible.

Light can be produced in the form of flashes, which attract the attention of the user, for example in the case of an incoming call.

Une antenne pour un émetteur-récepteur tel que celui de la figure 1 est représentée sur la figure 2.An antenna for a transceiver such as that of Figure 1 is shown in figure 2.

L'antenne représentée en A comprend une enveloppe 6, faite d'un matériau translucide, et un support mécanique 7, qui supporte par tout moyen connu l'enveloppe 6 et au travers du quel passe un conduit de lumière 9, dans lequel une diode électroluminescente 10 peut envoyer de la lumière.The antenna shown in A comprises an envelope 6 made of a material translucent, and a mechanical support 7, which supports the envelope by any known means 6 and through which passes a light pipe 9, in which a diode light emitting 10 can send light.
