In one embodiment, the artificial nail body 110 has an area greater than the area of the natural nail and may have a shape corresponding to the natural nail. It should be understood that the scope of the present invention is not limited by the material and the shape of the artificial nail body 110 and that the artificial nail body having various materials and shapes in the art And a printed circuit board 120 according to the present invention, which will be described below, are to be construed as belonging to the scope of the present invention.

In one embodiment, the printed circuit board 120 may correspond to a flexible printed circuit board having flexibility. Accordingly, the printed circuit board 120 can be attached flexibly corresponding to the curved shape of the artificial nail body 110.

In one embodiment, the printed circuit board 120 may include a light emitting device, a light emitting device drive switch, a light emitting device drive switch activating part, and a power supply part. Here, the light emitting device, the light emitting device drive switch, the light emitting device drive switch activating part, and the power supply part are configured on the printed circuit board 120 and can be electrically connected to perform predetermined operations, respectively.

The light emitting device according to the present invention corresponds to an electronic device that is formed on the printed circuit board 120 and emits light when power is supplied thereto, and may correspond to an LED in one embodiment. In the meantime, a light emitting device provided in the artificial nail 100 according to the present invention corresponds to an LED, but it is not intended to limit the scope of the present invention. That is, it is understood that the light emitting device according to the present invention is an element that is formed on the printed circuit board 120 and emits light through power supply.

The light emitting device drive switch controls the power supply to the light emitting device to control the on / off operation of the light emitting device. In one embodiment, the printed circuit board 120 may further include a light emitting device drive switch activating portion for controlling an active state of the light emitting device drive switch. The light emitting device driving switch activating unit according to an embodiment of the present invention may correspond to a circuit configuration for maintaining the light emitting device driving switch in the inactive state and switching the light emitting device driving switch to the active state at the actual use time.

In one embodiment, the light emitting device driving switch may correspond to a Hall switch for controlling ON / OFF of the light emitting device through a magnetic force applied to the outside. The control circuit for constituting the light emitting device driving switch according to the present invention as a hall switch will be described in detail with reference to FIG. 2 to FIG.

The power supply unit may correspond to a power supply circuit that is electrically connected to the light emitting device and the light emitting device drive switch to supply power. In one embodiment, the power supply may comprise a power supply, wherein the power supply may correspond to a disposable battery.

Hereinafter, a printed circuit board 120 according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 to 7. FIG. 2 to 7 illustrate an embodiment in which the Hall switch is constituted by a light emitting device drive switch, and at least a part of each component to be described below is divided into equal parts It is to be understood that the present invention is not limited thereto.

2 and 3 are circuit diagrams for explaining the operation of the Hall switch according to an embodiment of the present invention.

The Hall switch 220 according to an embodiment of the present invention corresponds to an electronic device capable of controlling ON / OFF of a light emitting device through a magnetic force applied to the outside. Here, the Hall switch 220 is an element that can control the ON / OFF of the output terminal voltage using a Hall effect, and is generally known as a Hall switch or a Hall effect switch. The power of the output terminal can be supplied or cut off when a magnetic force is applied thereto.

That is, according to an embodiment of the present invention, a user can easily control the light-emitting device provided on the artificial nail 100 through an object having a magnetic force, such as a magnet or a speaker, from the outside.

In one embodiment, the Hall switch 220 may correspond to a latch-type switch that can sequentially switch the power supply state and the power-off state of the output terminal in accordance with the supply of the magnetic force and maintain the switched state. For example, when the user applies a magnetic force from the outside through the magnet, the hall switch 220 is switched from the power supply state (LED ON) to the power cutoff state (LED OFF), and the power cutoff state The same operation can be performed in the opposite case.

2 and 3, the Hall switch 220 may include a chip enable terminal CE, a ground terminal GND, a power supply terminal VDD, and an output terminal OUT. Here, the Hall switch 220 is activated when a certain voltage is applied to the chip activation terminal CE, and can operate in an inactive state when the voltage is not applied.

2, when the voltage VDC is applied to the chip activation terminal CE of the Hall switch 220, the Hall switch 220 operates in an active state, and according to an external magnetic force, (210) can be turned on and off. More specifically, every time the external magnetic force is applied in the active state, the Hall switch 220 sequentially switches the connection of the output terminal OUT and the ground terminal GND to an open and a closed state, So that the LED 210 electrically connected between the power supply terminal VDD and the output terminal OUT can be controlled to be turned on and off.

For example, when the Hall switch 220 is in the activated state and the initial power OFF state (LED OFF), when the user externally applies a magnetic force through the magnet, the output terminal OUT of the hose position 220 and the ground terminal The GND is electrically closed so that the LED 210 electrically connected between the power supply terminal VDD and the output terminal OUT can be turned ON. On the other hand, when the Hall switch 220 is in the activated state and the initial power supply state (LED ON), when the user externally applies a magnetic force through the magnet, the output terminal OUT of the hole position 220 and the ground terminal GND The LED 210 electrically connected between the power supply terminal VDD and the output terminal OUT may be turned off.

3, when the chip activation terminal CE of the hall switch 220 is grounded (GND), the hall switch 220 is maintained in an inactive state that is not responsive to external magnetic forces.

As described above, the Hall switch 220 according to one embodiment of the present invention can operate in the active and inactive states. Here, it is necessary to keep the Hall switch 220 active to control the light emitting device through the external magnetic force. However, since the hall switch 220 requires a standby current (about several hundreds of uA) for reacting to the external magnetic force in the active state, considering the limited power capacity of the small battery, To keep the standby current to a minimum (about several uA).

Hereinafter, a light emitting device drive switch activating unit capable of maximizing the efficiency of the power supply unit included in the power supply unit 230 will be described in detail with reference to FIG.

4, the light emitting device driving switch activating part 240 may be formed on at least a part of the line electrically connecting the chip activating terminal CE of the hall switch 220 and the ground terminal GND. The Hall switch 220 is electrically connected to the power supply unit VDC of the power supply unit 230 so that the light emitting device drive switch activating unit 240 is electrically connected to the chip activation terminal CE and the ground The terminal GND can be closed so that the Hall switch 220 is kept in the inactive state.

For example, the light emitting device drive switch activating portion 240 is formed to include the A and B nodes formed in the line electrically connecting the chip activation terminal CE and the ground terminal GND, and the A and B nodes are short- the CE terminal is connected to the ground terminal GND so that the hall switch 220 can be kept in the inactive state regardless of the power source VDC.

In one embodiment, the printed circuit board 120 may configure resistors 250 and R2 between the lines that electrically connect the chip activation terminal CE and the power supply 230. Accordingly, the resistors 250 and R2 can limit the standby current of the power supply unit 230 to a predetermined magnitude in the inactive state of the hall switch 220. [ The resistor R2 is provided to minimize the current flowing in the ground terminal GND in accordance with the power supply VDC in the inactive state of the Hall switch 220 and to have a high resistance value .

In one embodiment, the Hall switch 220 can be switched to the active state when the light emitting device drive switch activating part 240 is physically disconnected. The chip activation terminal CE and the ground terminal GND are electrically opened so that the chip activation terminal CE is electrically connected to the power supply VDC Is applied, the Hall switch 220 can be switched to the active state.

For example, the user can switch the hole switch 220 to an active state by physically disconnecting the node A and node B, which are the light emitting device drive switch activating unit 240 according to an embodiment of the present invention. Therefore, the artificial nail according to an embodiment of the present invention maintains the inactive state of the hall switch 220 in the distribution process, and at the time of actual use, the user disconnects the light emitting device driving switch activating part 240, ) To an active state, it is possible to minimize the power consumed in the circulation process of several months.
