[Background of the invention]

 Recently, there has been a remarkable spread of the above-mentioned mobile communication devices, and at present, in addition to their miniaturization and weight reduction, their unique designs have become a major factor for consumers to purchase.

Further, since the ring tone of the mobile communication device may be annoying to people around the mobile communication device, a device that gives vibration instead of the ring tone is known. Nowadays, to improve the visibility of outgoing and incoming calls and to enhance a kind of fashion, a light emitting element is installed at the tip of the antenna, and the light emitting element is used to transmit and receive electromagnetic energy generated by the mobile communication device when receiving a call. The ones that emit light by exchanging them are disclosed.

[0004]

[Problems to be solved by the invention]

 However, the antenna of the mobile communication device described above is uniform and the taste of the owner cannot be fully satisfied, and as the size of the mobile communication device itself is reduced, However, there has been a problem that miniaturization of an antenna that emits light cannot be followed.

[0005]

[Purpose of the invention]

 Therefore, the present invention has been made with a focus on the conventional situation, and enhances visibility, further enhances fashionability, and has a variety of colors that sufficiently satisfy the taste of the owner. In addition, it aims to provide an antenna for a mobile communication device that can be freely reduced in size according to the actual situation.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the antenna of the mobile communication device according to the present invention has a capacitor connected to one end, a rectifier diode connected to the other end of the capacitor, and both ends of the light emitting element connected to the rectifier diode. The light emitting element is illuminated by capacitively coupling the electromagnetic wave emitted from the mobile communication device main body by the capacitor, and the light emitting element of the mobile communication device accommodated in the translucent cap cover. The antenna is characterized in that the light emitting element is one or more chip LEDs.

[0007]

[Action]

 With this configuration, there is no monotony, an eye-catching effect by light emission is obtained, a change in light emission color is obtained, and in addition, blinking or a pseudo effect thereof is obtained. In addition, it can be made fashionable, and can be made more compact.

[0008]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a main part of an antenna of a mobile communication device embodying the present invention, FIG. 2 is a circuit diagram, FIG. 3 is a diagram showing a second embodiment, FIG. FIG. 9 is a plan view of a principal part showing a third embodiment in the same manner.

In these figures, 1 is a coil connected to the tip of an antenna (not shown), and 2 is a substrate. The substrate 2 is continuous in the longitudinal direction of the antenna, and the first chip LED 3 and the second chip LED 4 are mounted on both sides of the substrate 2 in a back-to-back state, that is, at a pitch of 180 degrees. Note that the first chip LED 3 and the second chip LED 4 can be arranged side by side without being set at the 180-degree pitch, or they can be arranged in several rows and multiple stages.

[0010] In the drawing, reference numeral 5 denotes a cap cover for protecting the first chip LED 3 and the second chip LED 4 and transmitting light to the outside. The cap cover is formed of a plastic such as acrylic. Is done. The cap cover 5 may be subjected to processing such as diamond cutting or ridge forming in order to further scatter light emitted from the chip LEDs 3 and 4, and in some cases, may be subjected to smoke processing to provide a different light effect. You can do it.

In the first embodiment, a capacitor 6 is assembled in parallel with the coil 1 connected to the antenna body, and the coil 1 is connected to the anode side of a first rectifier diode 7. The rectifier diode 7 has a configuration in which the cathode side is connected to the anode side of the first chip LED3.

On the other hand, reference numeral 8 in the figure denotes a second rectifier diode, the second rectifier diode 8 having a cathode connected to the coil 1 and an anode connected to the cathode of the second chip LED 4. That is, the first chip LED 3 and the second chip LED 4 emit light simultaneously when used. It should be noted that the first and second chip LEDs 3 and 4 may emit the same color, or may have any two colors.

FIGS. 3 and 4 show a second embodiment of the present invention. In this case, three chip LEDs 9, 10, and 11 are arranged in a vertical direction, or in a horizontal direction, or at a pitch of 120 degrees. The emission colors of the three chip LEDs 9, 10, and 11 are set to red, green, blue, or white, respectively.

In the circuit of the second embodiment, the coil 1, the capacitor 6, the first rectifier diode 7, and the second rectifier diode 8 are the same as those of the first embodiment, but the first rectifier diode The anode side of a chip LED 9 having a red or green emission color is connected to the cathode side of 7, and the anode side of a chip LED 10 having a red or green emission color is connected in series to the cathode side of the chip LED 9. I have.

In the second embodiment, the anode side of the second rectifier diode 8 is connected to the cathode side of a chip LED 11 having a blue emission color, so that three colors emit light simultaneously. ing.

FIG. 5 shows a third embodiment of the present invention. In this case, a plated coil 14 is provided between a pair of chip LEDs 12 and 13, and a luminous film is provided in the coil 14. The light-emitting film 15 can be replaced with a reflector film. By arranging the light-emitting film 15 or the reflector film, the light emitted from the chip LEDs 12 and 13 causes irregular reflection, and a glittering state can be obtained.

It should be noted that the first rectifier diode 7 and the second rectifier diode 8 described above can provide the same effect even if only the first rectifier diode 7 is used. Further, when three chip LEDs are used, they can be arranged obliquely or spirally, and can be arranged in several rows.

The substrate on which the chip LED is mounted can also be rotated by, for example, incorporating a magnet, and the chip LED is rotated in a light emitting state. .
