Description

Electronic card having a light emitting device {ELECTRONICS CARD WITH LIGHTING EMITTING DEVICES}

The present invention relates to an electronic card having a light emitting element.

PLCC stands for Private Label Credit Card and is a commercially available credit card. Credit card companies can reduce the cost of attracting new subscribers by putting the brand of a specific company on a credit card and providing benefits and services focused on that company. In addition, the subscriber has an effect of increasing royalty by having his or her own credit card.

However, in the current situation where competition in the relevant market is fierce, it is becoming increasingly difficult to secure differentiation in terms of product value simply by applying the affiliate brand to the design of the existing card.

Therefore, in recent years, products made of metal materials such as titanium and aluminum are being released for the purpose of intensifying competition and differentiation in terms of product value. An example of such a conventional electronic card is introduced in FIG. 1 .

1 is a diagram showing a conventional electronic card.

Referring to FIG. 1, a conventional electronic card using a metal material includes a printing layer 1, a metal layer 2, a shielding layer 3 having a laminated PVC structure, an inlay sheet 4 including an antenna coil, and an electronic card. It consists of a COB (5) containing a card chip. This is called a half-metal structure.

Specifically, the conventional metal card has a metal feel on the upper side by laminating the printing layer 1 made of a thin transparent film on the upper side of the metal layer 2, but the lower side has a shielding sheet 3 and an inlay sheet ( 4) is placed, so it has the same feasibility as a PVC card, so it shows the effect of reducing the feeling of a metal card by half. However, such a conventional metal card has a half-metal structure, and when viewed from the side, the metal layer 2 and the inlay sheet 4 are clearly visible, which can be a factor in reducing aesthetics.

In addition, the conventional metal electronic card has a structure in which an antenna coil is pulled out and directly soldered to the RF connection terminal 512 of the COB 5, and manufacturing costs are high because this manufacturing method is inevitably performed manually.

In addition, since the conventional metal type electronic card has no additional functional components other than the presence of a layer of metal material, it is difficult to provide scarcity of product value as a PLCC.

Therefore, in recent years, development has been carried out with the aim of improving the performance of contactless electronic cards equipped with RF antennas for performance improvement, rather than simple design modification as described above. development did not take place.

The circuit board module 500 is commonly applicable to the first and second embodiments. Hereinafter, it will be described in detail with reference to FIGS. 6 to 10 .

FIG. 6 is a diagram showing the circuit board module 500, and FIG. 7 is a diagram showing the RF antenna unit 510.

Referring to FIGS. 6 and 7 , the circuit board module 500 is characterized in that a module board 530, an RF antenna unit 510, and an LED antenna unit 520 are included in one board.

The module substrate 530 supports the RF antenna unit 510 and the LED antenna unit 520 as a substrate made of a flexible material.

The RF antenna unit 510 includes an RF antenna pattern 511 forming a loop along the edge area of one surface of the module substrate 530 and an RF connection terminal 512 to which the start and end ends of the RF antenna pattern 511 are connected. can include

The RF antenna pattern 511 is a copper foil material pattern and extends along the edge of the substrate. At this time, the start and end ends of the RF antenna pattern 511 are connected to different electrodes of the RF connection terminal 512, respectively.

The RF connection terminal 512 is a copper plate and may include a pair of terminals to which the start and end ends of the RF antenna pattern 511 are respectively connected. Here, the RF connection terminal 512 may be a semiconductor chip of the card module 210 mounted or a bus extending to the semiconductor chip may be connected.

The LED antenna unit 520 is installed in the inner region of the module substrate 530 where the RF antenna unit 510 is installed. Here, as the LED antenna unit 520 forms a loop-shaped pattern adjacent to the RF antenna unit 510 extending along the outer rim of the module substrate 530, the interaction with the RF antenna pattern 511 results in an induced electromotive force. can amplify.

In addition, the LED antenna unit 520 is installed on both sides of the module substrate 530 to form mutually overlapping regions to evenly distribute the induced electromotive force. A description of the LED antenna unit 520 will be described with reference to FIGS. 8 and 9 .

8 is a circuit diagram of the LED antenna unit, and FIG. 9 is a detailed view of the LED antenna unit.

Referring to FIGS. 8 and 9 , the LED antenna unit 520 includes a plurality of LED antenna patterns 521 , 522 , and 523 and an LED connection terminal 524 on which the light emitting element 220 is mounted.

The plurality of LED antenna patterns 521 , 522 , and 523 supply power to the light emitting element 220 by inducing and generating electromotive force when a signal is received in a non-contact manner. That is, the LED antenna patterns 521, 522, and 523 supply driving power so that the light emitting element 220 can emit light.

Therefore, in the present invention, the LED antenna patterns generate induced electromotive force by the received signal at the same time as the signal is received by the card module 210 so that the light emitting element 220 emits light.

In addition, the plurality of LED antenna patterns are distributed and installed on both sides of the module substrate 530, and have mutually overlapping regions to induce electromotive force between the antenna patterns on both sides. At this time, the electromotive force induced in the overlapped area is evenly distributed among the plurality of light emitting elements 220 connected in parallel.

For example, a first LED antenna pattern 521 and a plurality of LED connection terminals 524 connected in parallel to the first LED antenna pattern 521 are formed on the first surface of the module substrate 530, and the module substrate On the second surface of 530, a second antenna pattern, a third LED antenna pattern 523, and a plurality of LED connection terminals 524 are formed.

Here, the plurality of LED connection terminals 524 formed on the first and second surfaces are mutually energized through via holes. That is, the LED connection terminals 524 in the module substrate 530 are connected in parallel.

The first LED antenna pattern 521 is arranged in a loop shape extending from the outside of the LED connection terminal 524 by a predetermined length. Here, the first LED antenna pattern 521 extends from the first surface of the module substrate 530 in a first direction.

The first direction corresponds to a direction from the first side 531 to the opposite second side 532 side.

At this time, the length of the first LED antenna pattern 521 extending in the first direction may be extended to have a length of more than half of the total length (eg, at least 1/2, at most the total length in the first direction).

The second LED antenna pattern 522 and the third LED antenna pattern 523 are disposed symmetrically on the second surface of the module substrate 530. Here, the area of the first LED antenna pattern 521 disposed on the first surface and the sum of the second LED antenna pattern 522 and the third LED antenna pattern 523 disposed on the second surface are equal.

That is, the total area where the second LED antenna pattern 522 is disposed corresponds to 1/2 of the total area where the first LED antenna pattern 521 is disposed.

In addition, the second LED antenna pattern 522 and the third LED antenna pattern 523 extend in a second direction from a position opposite to the first LED antenna pattern 521 on the second surface.

Here, the second direction is the opposite direction to the first direction, and the second direction corresponds to the side of the first side 531 from the second side 532 .

At this time, the extension length (b) of the second LED antenna pattern 522 and the third LED antenna pattern 523 in the second direction is the minimum of the total length between the first side 531 and the second side 532. 1/2, may correspond to a maximum of the entire length in the second direction.

Therefore, between the first LED antenna pattern 521 formed on the first surface of the module substrate 530, the second LED antenna pattern 522 and the third LED antenna pattern 523 formed on the second surface, the overlapping area ( c) exists. In this overlapping area, LED antenna patterns respectively installed on the first and second surfaces can be mutually overlapped to generate a uniform electromotive force.

Therefore, the plurality of light emitting elements 220 can output light of uniform intensity as light is emitted by a uniform electromotive force, so that the light emitting intensity of the plurality of light emitting elements 220 is uneven due to a lack of power or an imbalance in supply power. problems can be avoided.

As described above, the present invention configures the circuit board module 500 in which the RF antenna and the LED antenna are integrally formed inside the metal body 100, so that the user can check whether the electronic card is operating normally through the light emitting signal of the LED when using the electronic card. You can check.

In addition, the present invention can further amplify the induced electromotive force due to the influence between the RF antenna pattern 511 and the LED antenna pattern, so that the communication distance can be improved, and a larger number of light emitting elements 220 can be mounted.

In addition, according to the present invention, as the LED antenna patterns are arranged to have mutually overlapping areas, uniform electromotive force can be supplied to a plurality of light emitting elements 220 connected in parallel, so that all light emitting elements 220 emit light with uniform intensity. can do.

In addition, the present invention functions to emit light from one surface of an electronic card having a metal body 100 by using the improvement of communication performance of the circuit board module 500 and the effect of uniform output, It was possible to implement a linear light emitting function of outputting light through the perforation 111 extending linearly from one side.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above, and is common in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims. Of course, various modifications and implementations are possible by those with knowledge of, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
