Description

Simulation device of sunrise / sunset to induce natural weather and sleep and its method {DAWN / DUSK SIMULATOR FOR THE INDUCTION OF WAKEFULNESS / SLEEP AND PROCESS THEREOF}

The present invention is to induce natural weather and sleep to easily select the exponential, transcendental or sigmoid-type lighting / flashing pattern to induce weather and sleep using the light / flashing light Regarding the simulation device of the sunrise / sunset for the same,

More specifically, at a certain time before sunrise, the illuminance of the bedroom is gradually increased by using lighting lamps to resemble sunrise, and the lighting environment is created to be similar to sunset at bedtime. In order to wake up naturally at the time you want to wake up, and to induce sleep comfortably, and to more closely simulate the illumination change pattern at sunrise, the brightness of the lamp is exponential, hyperbolic or sig In addition to increasing the shape of the sigmoid, it is possible to adjust the slope of the lighting / flashing pattern considering the difference in the response of the object to light, which is precisely applied to the body such as the user's brain. The natural weather and sleep that maximize the reliability of biotechnology to increase overall satisfaction. It relates to a simulation apparatus and method of the sunrise / sunset for attempting.

In general, an alarm clock or a vibrating alarm clock is used as a means to induce wakeful weather for a user who is sleeping. This means that sound and vibrations directly affect the reticular activation system (RAS) of the brain stem during sleep. Stimulation will induce arousal (ie weather).

At this time, the sound or vibration only wakes the user's sleep while sleeping, and other biological rhythms (eg, body rhythm, hormonal rhythm) are not awakened, so that the internal dysynchronization of the user is disrupted. ), Which causes more troubles such as fatigue and stress.

In order to solve the above problem, light such as an alarm clock having a large difference conceptually from an alarm clock or a vibrating alarm clock is used as a weather guide means.

That is, the light of the illumination lamp induces arousal state (ie, weather) by indirectly stimulating the reticular body through a biological clock located in the suprachiasmatic nucleus (SCN) of the hypothalamus. Light wakes all biological rhythms together because it induces an awakening state through the biological clock, and thus does not cause internal disharmony, which is the most natural means of meteorological guidance.

As mentioned above, the device for inducing the weather using light is already in commercialization stage in foreign countries and Korea, and recently, a company called Filux (http://www.feelux.com) has released related products. There is a fundamental problem because the pattern of increase in illuminance that is implemented is linear.

In other words, in order to induce the awakening state through the biological clock, an exponential increase pattern (increase of roughness of about 4 log units in 30 minutes), which is a change pattern of illuminance at sunrise, should be simulated. Due to the increase in illuminance pattern, a relatively strong light is initially presented and the brainstem reticulum is directly stimulated, and the light stimulus suddenly awakens through the brainstem reticulum before inducing the awakening state through the biological clock. Inducement will result.

In this case, the sound or other somatic stimulus becomes like inducing an arousal state and loses the advantage of using light as a weather guide means.

In addition, there is a problem that the user of the conventional meteorological induction apparatus using light can not set the increase pattern of the illumination intensity arbitrarily.

Therefore, due to the problems described above, the conventional weather guidance apparatus includes a large defect that decreases the reliability of biotechnology, which is extremely precise in applying to a body such as a user's brain.

The present invention has been made to solve the problems of the prior art as described above has the following object.

The present invention gradually increases the illuminance of the bedroom at a specific time before sunrise by using a lighting lamp so as to be similar to sunrise, and to create a lighting environment to resemble sunset at bedtime, so that the user can wake up The goal is to get up naturally at the same time and to induce sleep comfortably.

Another object of the present invention is to increase the brightness of the lamp in the form of exponential, transcendental or sigmoid in order to more closely simulate the illumination change pattern at sunrise to consider the difference in response of the individual to the light. The inclination of the lighting / flashing pattern can be adjusted.

Still another object of the present invention is to simulate the sunrise / sunset to induce natural weather and sleep to maximize the reliability of biotechnology that must be precise in applying to the body, such as the user's brain and overall use satisfaction and its To provide a method.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment for achieving the above object of the present invention will be described in detail.

In the above-mentioned wake-up mode, the sound / music specified by the user such as bird sound, wave sound, melody, etc. is replaced by the sound source chip instead of the beep sound that is output through the speaker while the light is maintained after the lighting is completed. To output.

On the other hand, the present invention may be variously modified and may take various forms in the above apparatus and method.

It is to be understood, however, that the present invention is not limited to the specific forms referred to in the above description, but rather includes all modifications, equivalents and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood to do.

In the above-described apparatus, first, the power supply unit 10 converts AC power into DC power to use as a power source for lighting.

This converts the input commercial power (220V / 60mA) into an uncontrolled 280V DC using a rectifying bridge diode (BD) and then adopts a smoothing capacitor (C1) to enable constant voltage and stable current supply. To DC.

At this time, in order to drive the power supply unit 10 stably, a fuse and a load resistor R are connected to a commercial power supply input terminal to prevent an overload or a sudden inrush current.

The illumination brightness designation unit 20 specifies the brightness of the lamp (Lamp) to the degree desired by the user using the DC link voltage supplied from the power supply unit 10.

Since the commercial power cannot specify the brightness of the lighting as the user wants (0-220V) without changing the voltage, current and frequency, the voltage source of the DC link stage is PWM (Pulse Width Modulation) technique. The overall voltage and current values were changed to a waveform similar to AC, and the PWM was switched using a semiconductor device (Power FET).

The gate driver 30 is configured to insulate the power of the illumination brightness designation unit 20 and the power of the lamp to protect the circuit (see FIG. 2).

The keypad 40 is a means for inputting data desired by the user, and inputs information on the current time, the brightness of the light and the lighting / flashing.

The switch unit 50 includes a lamp switch SW1, a bib switch SW2, and an overall switch SW3, and the lamp switch SW1 is a lamp. ) Control the on and off signal, and the beep switch (SW2) is to control the sound signal generated at the alarm time, the overall switch (SW3) to control the bib and the lighting at the same time It is for.

The display unit 60 is made of liquid crystal (LCD), and the user can easily check the current time and information input through the keypad unit 40, which can display 2 Line 16 Digits. ) To implement the watch's function of displaying the current time and the user interface to check the information entered by the user.

The microprocessor (CPU) 70 compares the input data and outputs a control signal corresponding thereto to appropriately control the operations of the components.

Therefore, the microprocessor unit (CPU) 70 supports three PWMs, four HSIs, and HSOs, and uses a 20 MHz system clock to provide a fast operation speed. In particular, the PWM terminal provides a duty ratio. As it provides resolution of max. 1 ~ 255, when the DC voltage is PWM, the effect of lighting and blinking gradually appears in the lamp which is the load.

In addition, in order to provide the maximum convenience and convenience to the user, a conventional RS-232 cable capable of serial communication between the microprocessor unit 70 and the personal computer (PC) 100 is connected, and the personal computer 100 ) Is a built-in MMI (Man-Machine Interface) program that can input a variety of information, such as the keypad (50).

The MMI (Man-Machine Interface) program is provided to be easily compatible with a normal window operating system, which can edit or store an illumination pattern or a user-configured illumination pattern. The illuminance pattern is displayed on a PC monitor in the form of a graph so that the user can directly check the increase and decrease of the illuminance.

Description of the specific menu for the MMI program will be described below.

In the method of the present invention, the present time is first inputted through the keypad 40 (S1), and then the wake-up mode (S10), the sleep mode (S20), or the like. The user's desired mode is selected from the integrated mode S30.

In this case, when the wake-up mode (S10) is selected, the user selects a desired lighting pattern and inclination (S11), and then turns on the keypad unit 40 to start and finish the lighting. Input (S12) through.

After the above lighting start and completion time are input (S12), the brightness of the lighting at the time of completion of lighting and the lighting duration information after the completion of lighting are input (S13).

In addition, when the user selects the sleep mode (S20), after selecting the illumination pattern and the slope (S21), the start of the flashing and the completion time of the illumination is input through the keypad 40. (S22), and after inputting the above start and completion time of the flash (S22), the brightness information of the illumination at the start of flashing is input (S23).

In addition, when the user selects the integrated mode (S30), the illumination pattern and the slope is selected (S31), and then the flashing / lighting start and completion times of the lights are input through the keypad 40, respectively. After the input S32 is completed, the brightness of the lighting is input at the time of completion of lighting and the start of blinking, and the lighting duration information after the completion of lighting is input at step S33.

When the input of the information is completed through the keypad unit 40, the user can confirm through the liquid crystal (LCD) of the display unit 60, the microprocessor unit 70 is a signal to operate in accordance with the input information Will print

At this time, when the user selects and executes the wake-up mode (S10) among the above modes, the present state (S1) and the start time (S12) of the comparison is compared (S14) when not the same state when the lighting state is not maintained On the other hand, when the present time (S1) and the start time (S12) of the comparison is the same (S14), the application rate (Duty) is increased (started in the off state, S15).

When the lighting completion time inputted above is reached (S16) while increasing the above-mentioned duty ratio, the bib switch SW2 is operated to output a sound alarm through the speaker and at the same time the maximum brightness of the lighting is continuously maintained. If the input duration of the sound alarm and the maximum brightness of the lighting is terminated (S18), the lighting is turned off and the sound alarm is turned off (S2).

In addition, when the user selects the sleep mode (S20) or the integrated mode (S30) from among the above modes, the input current time (S1) and the flashing start time (S22, S32) are respectively compared (S41). If it is not the same, the lighting state is kept on, and the present time (S1) and the flashing start time (S22, S32) are compared (S41), respectively, and if the same, the ratio (Duty) is reduced (at the maximum brightness). Start, S42)).

At this time, when each of the input flashing completion time is reached (S43), if the selection of the sleep mode or the integrated mode is selected (S44), and if the integrated mode is selected, the process for the wake-up mode is performed (S14). S18), when the sleep mode is selected, the illumination is turned off and the sound alarm is turned off (S2).

As described above, in the case of selecting the integrated mode, first, the light blinks according to the information input by the user, and the light after completion of the flashing is turned off until the wake-up mode is executed. The lighting starts based on the previously entered information.

At the same time as the above lighting is completed, a beep sound, which is a sound alarm, or another sound (music / sound) selected by the user is output through a speaker while the light is maintained for a preset time, and the beep The sound is generated using the HSO supported by the microprocessor unit 70, and the additional sound (bird sound, wave sound, melody, etc.) may be provided through a sound source chip.

In addition, when only one of the sleep mode and the wake mode is selected, the other unselected function is kept in a stopped state, and after the execution cycle of the selected mode is completed, the user resets separately. If you do not do this, the sleep mode or wake mode will be automatically executed at the set time.

In selecting the illumination pattern and the slope, one of an exponential function, a transcendental function, or a sigmoid form is selected to implement an illumination intensity change pattern most suitable for inducing sleep and weather of a user (individual).

That is, Figure 4 shows a linear increase in the intensity of illumination (linear), which is conventionally performed, which is a relatively strong light is initially presented to the situation where the brain stem network is directly stimulated. Induce a sudden arousal

However, as shown in FIG. 5 and FIG. 6, an increase or decrease pattern of illumination in the form of an exponential function, a transcendental function, or a sigmoid increases the illuminance of the bedroom at a specific time before sunrise, similar to that at sunrise. At the same time, it is possible to create a lighting environment similar to sunset at bedtime, thereby preventing fatigue and stress due to internal incongruity, inducing to occur naturally at the time of waking up and inducing a comfortable sleep.

In addition, the user can arbitrarily specify the brightness of the lamp, the start and completion time of the lighting / flashing, and the duration of the lighting after the completion of the lighting, so that the user can search for the most appropriate dose of light. .

Figure 7 is a graph showing the lighting operation according to the user's input, which is the brightness of the lamp 220V (100%), the blinking time of the lamp in the sleep mode to 60 minutes, Sigmoid It is the case that the lighting operation is input and set so as to gradually decrease in the form, and in the wake-up mode, it is the lighting section of 60 minutes which increases exponentially steeply and the lighting is set to be maintained for 20 minutes after the lighting is completed. will be.
