  Embodiments of a skin beauty device according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference numerals and redundant description is omitted. FIG. 1 shows a block diagram of a skin beauty device according to the first embodiment. The skin beauty device according to the first embodiment includes an LED 10. The LED 10 is implanted on a wall surface of an appropriate container or case in order to irradiate light toward the human skin 90. The LED 10 is a single element and can emit light of any one of red, green, and blue. Holding the container or case in hand, the LED 10 is moved closer to the skin 90, or when the container or case is fixed, the required part of the person is moved so as to bring the human skin closer to the LED 10.

  The skin beauty device of this embodiment includes a power supply circuit 11, a driving power generation unit 20, a waveform shape changing unit 12, a waveform shape instruction unit 13, an input interface 14, and a modulation circuit 15 in addition to the LED 10 described above. The power supply circuit 11 supplies power to the drive power generation unit 20, the waveform shape changing unit 12, the waveform shape instruction unit 13, the input interface 14, and the modulation circuit 15.

  The drive power generation unit 20 generates drive power for driving the LED 10. The waveform shape instructing unit 13 includes, for example, a key or a switch for inputting the waveform power instruction information of the driving power. The waveform shape changing unit 12 changes the waveform shape of the driving power to a waveform for AC driving for the LED based on the waveform shape instruction information input from the waveform shape indicating unit 13.

  The drive power generation unit 20 includes a drive power generation circuit that generates drive power having a plurality of (here, five) waveform shapes. The five drive power generation circuits are a first drive power generation circuit 21, a second drive power generation circuit 22, a third drive power generation circuit 23, a fourth drive power generation circuit 24, and a fifth drive power generation circuit 25.

  The first drive power generation circuit 21 generates and outputs a constant value power waveform (DC waveform) as shown in FIG. The second drive power generation circuit 22 generates and outputs a sine wave power waveform as shown in FIG. The third drive power generation circuit 23 generates and outputs a square wave power waveform as shown in FIG. The fourth drive power generation circuit 24 generates and outputs a triangular wave power waveform as shown in FIG. The fifth drive power generation circuit 25 generates and outputs a sawtooth power waveform as shown in FIG.

  From the waveform shape instructing unit 13, a selection signal for selecting any one of the above-described constant value power waveform, sine wave, square wave, triangular wave, and sawtooth wave can be sent to the waveform shape changing unit 12 by a key operation or the like. The waveform shape changing unit 12 turns on one of the first driving power generation circuit 21 to the fifth driving power generation circuit 25 based on the selection signal. In the present embodiment, the shape of the power waveform and the type of waveform (five types) are described above, but this is only an example. For example, a waveform in which a burst appears within a predetermined time at a predetermined interval, etc. A waveform and an appropriate number of types can be generated. Then, the waveform shape instructing unit 13 outputs a selection signal for selecting one of these power waveforms, and the waveform shape changing unit 12 generates any one of the power waveforms, and the waveform amplitude and duty are as follows. Processing for changing at least one of the ratio and the frequency (signal parameter) is performed.

  That is, the waveform shape instructing unit 13 can send an instruction signal for changing at least one of the amplitude, duty ratio, and frequency (signal parameter) of the waveform of the drive power to the waveform shape changing unit 12. The waveform shape changing unit 12 sends a control signal to one of the first driving power generation circuit 21 to the fifth driving power generation circuit 25 that is turned on first, and controls the gain of the amplifier provided in the driving power generation circuit. At least one of oscillation frequency change control and duty ratio change control is performed. As described above, a desired drive power waveform is output from the drive power generation unit 20.

  The input interface 14 is used for inputting an external signal, and can be configured by an adapter that can insert and remove the plug in response to sending a music signal from a music player to the plug via a signal line. Other connecting parts can also be used. Further, when a signal is transmitted from a wired or wireless transmission circuit, the interface may be configured by a wireless reception unit (circuit).

  A modulation circuit 15 is connected to the input interface 14, and the modulation circuit 15 modulates an external signal input from the input interface 14 as a modulation signal using the waveform of the drive power generated in the drive power generation unit 20 as a carrier. To obtain a modulated signal. The modulated signal is supplied to the LED. In this embodiment, when the LED 10 is driven by a modulated signal, and the modulated signal is a music signal, the modulated signal becomes a signal for AC driving the LED 10, and the LED 10 blinks in time with the music, so that the same music is played. The listening user is aiming to feel like being stimulated by music. Therefore, basically, amplitude modulation can be adopted. Of course, the present invention is not limited to the above-described amplitude modulation, and various modulations such as a pulse width modulation that converts the upper and lower sides of the sound (amplitude of the modulation signal) into a duty ratio of the pulse and a combination of amplitude modulation and pulse width modulation are used. A scheme can be adopted.

  The waveform shape instructing unit 13 is provided with a key or the like for sending a control signal indicating whether or not to operate (use) the modulation circuit 15 to the waveform shape changing unit 12. When a control signal using the modulation circuit 15 arrives at the waveform shape changing unit 12, the waveform shape changing unit 12 puts the modulation circuit 15 into an operable state. On the other hand, when a control signal that causes the modulation circuit 15 to be in the inactive state arrives at the waveform shape changing unit 12, the waveform shape changing unit 12 puts the modulation circuit 15 into an inoperable state, and the drive power generated by the drive power generation unit 20. The control is performed so that the waveform is passed through and supplied to the LED 10.

  In the skin beauty device according to the first embodiment configured as described above, the waveform shape instructing unit 13 instructs to not use the modulation circuit 15, and a constant value power waveform, sine wave, square wave, triangular wave, An instruction indicating which of the saw waves to select and an instruction of parameters such as the amplitude, duty ratio, and frequency of the drive power waveform are input. For example, if there is an instruction not to use the modulation circuit 15 from the waveform shape instructing unit 13, the power waveform is one of the constant value power waveform, sine wave, square wave, triangular wave, and sawtooth wave shown in FIG. The power waveform whose waveform has been changed to the instructed amplitude, duty ratio, frequency, etc. passes through the modulation circuit 15 as it is and is supplied to the LED 10. The LED 10 is turned on when a current and voltage greater than or equal to a predetermined value are applied according to the waveform of the supplied power, and is turned off when the current and voltage are less than the predetermined value.

  FIG. 3 shows a square-wave drive power waveform in which the duty ratio is 50%, 25%, and 75% without changing the amplitude and frequency. It is assumed that the LED 10 is lit in the upward convex pulse. Then, the lighting rate per unit time increases in the order of 25%, 50%, and 75%, and the total amount of light per unit time increases. In other words, when the total light quantity per unit time is the light intensity, irradiation with a higher light intensity can be performed as the duty ratio increases. Further, the lighting time and the light-off time within one cycle of the LED 10 change depending on the duty ratio of the square wave, and the brightness of the LED 10 appears to change, and a change in the user's mood due to the change in brightness can also be expected.

  Further, for example, when the waveform shape instructing unit 13 gives an instruction to use the modulation circuit 15, the power waveform is one of the constant value power waveform, sine wave, square wave, triangular wave, and sawtooth wave shown in FIG. 2. Thus, the power waveform whose waveform is changed to the instructed amplitude, duty ratio, frequency, etc. is supplied to the modulation circuit 15. Here, it is assumed that a power waveform having a constant value as shown in FIG. 4A is selected and supplied to the modulation circuit 15.

  It is assumed that a music signal as shown in FIG. 4B is given to the input interface 14 as a modulation signal. The modulation circuit 15 uses the signal shown in FIG. 4 (a) as a carrier and modulates with the modulation signal shown in FIG. 4 (b) to obtain the modulated signal shown in FIG. 4 (c). This modulated signal is supplied to the LED 10 as drive power. The LED 10 is turned on when a current and voltage greater than or equal to a predetermined value are applied according to the waveform of the supplied power, and is turned off when the current and voltage are less than the predetermined value.

  The music signal as shown in FIG. 4B can be a signal of music that the user is listening to. Therefore, according to such a usage pattern, the user feels receiving light stimulation according to music, and light stimulation is performed on the skin in a relaxed situation. Thereby, it can be expected to further improve the effect of light stimulation.

The red control unit 52, the green control unit 53, and the blue control unit 54 can be configured by a PWM modulation circuit.

  When the control unit 51 receives the color instruction information, the control unit 51 instructs the red control unit 52, the green control unit 53, and the blue control unit 54 to specify the PWM modulation pulse width in accordance with the mixture ratio that realizes the color of the color information. Send. Accordingly, the red control unit 52, the green control unit 53, and the blue control unit 54 perform PWM modulation with the instructed pulse width on the power signal output from the modulation circuit 15, and output power. This PWM modulation can be performed within the convex portion of the signal.
