Electroencephalogram (EGG), one of these objective data, is an electrical signal that is noninvasively measured by an electrode attached to the surface of the brain.

The electrical activity of the brain reflected in brain waves is determined by neurons, gliacells, and blood-brain barrier, which are mainly caused by nerve cells. These brain waves can be divided into delta waves, seta waves, alpha waves, beta waves and gamma waves.

First, the delta wave (DELTA, δ) is an EEG with a frequency of 0-4 Hz. It occurs in deep sleep or coma, and can be detected as drowsy or inactive. These delta waves are predominantly seen in the deep sleep of normal people and in neonates.

Theta wave (THETA, Θ) is an electroencephalogram with a frequency of 4-8 Hz. It can be detected in a sleepy or drowsy state, a hypnotic state, a sleep state, or a light sleep state. These Cetaphas are distributed more frequently in children than in adults, which usually appear in the process of emotional stability or sleep. Memory, psychic, creativity, concentration, anxiety, and so on.

ALPHA (α) occurs when the brain waves have a frequency of 8-13 Hz and is stable in mind and body, such as relaxation, relaxation, and meditation, so that relaxation or calmness can be detected. This alpha wave is a stable EEG that predominantly appears in the occipital region. It is called a stable wave. The alpha wave appears mainly in a relaxed state such as relaxation of tension. In general, they appear continuously in the form of regular waves, with the greatest recorded in both genders and larynx and the smallest in frontal head. Especially when stable alpha waves appear, they close their eyes and are in a true state. When they open their eyes and look at an object, or become mentally excited, alpha waves are suppressed.

The beta wave (BETA, β) is an electroencephalogram with a frequency of 13-30 Hz, which occurs in a state of awakening when working in a tense state. From this, anxiety and tense can be detected. These beta-waves appear predominantly in the frontal lobe, and are often referred to as activity waves or stress waves because they occur mainly during daytime activity. These Beta waves appear mainly in the frontal areas, and appear when performing all conscious activities, such as when awake, when speaking. In an unstable state or in tension, it appears predominantly in complex computation processing.

Gamma wave (GAMMA, γ) is an EEG with a frequency of 30-50 Hz, and it occurs mainly when anxious or excited. Therefore, it can detect a state of anxiety due to high cognition and drug / alcohol.

FIG. 3 is a block diagram for explaining a concentration-enhanced illumination system using EEG for color according to the present invention in detail.

3, the color tester 100 may include an RGB light emitting unit 120, an RGB control unit 141, and a communication unit 142. The RGB light emitting unit 120, the RGB control unit 141, have.

The RGB light emitting unit 120 randomly divides the wavelength range of 380 to 710 nm, which is an area of the visible light ray that can be perceived by the user, and emits light by dividing each wavelength into predetermined wavelengths for a predetermined period of time. At this time, the emitted light may be controlled by the RGB control unit 141 configured therein, or may be controlled by a control signal transmitted from an external user terminal 300.

The RGB control unit 141 controls the light emitted from the RGB light emitting unit 120 to emit light by dividing each wavelength in the visible light region by a predetermined wavelength for a predetermined period of time.

The communication unit 142 receives the control signal of the RGB light emitting unit 120, which is controlled through the RGB control unit 141, from the external user terminal 300.

The brain wave measuring apparatus 200 measures a brain wave of a user, which is mounted on a head of a user who is a subject, and is changed by light emitted for a predetermined time at a predetermined wavelength set in the color tester 100, and wirelessly transmits the brain wave to the outside.

The user terminal 300 includes a communication unit 310, a memory unit 320, an application 330, and a control unit 340.

The communication unit 310 communicates with the color checker 100, the brain wave meter 200 and the illuminator 400 to control the color tester 100 to emit RGB light of various wavelengths by RGB light And receives the brain waves of the user as the subject from the brain wave measuring device 200. The illumination device 400 receives the control signal to be emitted by the color tester 100 together with the identification information of the user terminal 300 And transmits the result of receiving the user's brain waves to the light wavelength emitted.

The memory unit 320 may include control information for controlling the RGB light emitted from the color tester 100 to emit light by dividing a predetermined wavelength by a predetermined time and an RGB light wavelength emitted from the color tester 100 200 of the user EEG measurement data is received from the communication unit 310, the user EEG measurement data is stored.

The application 330 is a program that enables the color tester 100, the brain wave measuring device 200, and the illumination device 400 and the user terminal 300 to be interlocked.

And transmits and receives a control signal required by the color tester 100 through the application and a control signal and data for controlling the light to be emitted to the light wavelength to be emitted by each user in the illumination device 400. [

The control unit 340 controls the communication unit 310, the memory unit 320, and the application 330.

The lighting apparatus 400 includes a light emitting unit 410, a control unit 420, a memory unit 430, and a communication unit 440.

The light emitting unit 410 is an LED light emitting unit that emits RGB color light. Light emitting diodes (LEDs) are classified as monolithic LED displays and hybrid LED displays. Due to the characteristics of semiconductors, it has great advantages in terms of processing speed, power consumption, and life span. It is popular as an electronic display part of various electronic products, and it does not cause snowing or short-circuit of elements like conventional bulb lamp. It is manufactured in a small size and widely used as various display devices, and its lifetime is high due to its semi-permanent lifetime (about 1 million hours).

It is a semiconductor device that emits light. It is used in electronic display boards such as various electronic products and automobile instrument panel. LED light color can realize RGB color. Depending on the content of added impurities, the wavelength of the material differs. The wavelength ranges from 400 nm to 700 nm, which is the visible light region of human beings. Red is 700 nm, green is 565 nm, and yellow is 5 85 nanometers, and the orange color has a wavelength of 635 nanometers.

The control unit 420 controls the illumination color of the LED light emitting unit 410 based on the illumination color information transmitted from the communication unit 440 or the illumination color information stored in the memory unit 430, Refers to the illumination color information according to the identifier information, and emits the RGB light of the wavelength required by the user. For this, the illuminating device 400 may be configured to emit RGB color light of different wavelengths for each user according to the illumination color information for a plurality of users according to the user terminal identifier information through the memory, as described above.

In the color tester 100 of the present invention, twelve RGB colors are selected as complementary colors. The colors of complementary colors are opposite to each other. Red-green, red-yellow, orange-blue, orange-yellow, blue-yellow, yellow-green, yellow-green, . As an example, twelve complementary colors among 20 complementary colors can be selected.

Select a contrast background color, alternating between the two colors of the complementary color, and output a complementary color sample. For example, if the complementary color is red-cyan, the first is red and the second is cyan. And the third is red, and the fourth is repeated for a certain number of times or until it is selected as teal. By alternately outputting two colors, the contrast effect between the two colors is maximized. The maximized contrast effect as described above can ensure reliability and objectivity in user's color selection.

Here, the color tester 100 may select two background colors so as to be contrasted with a complementary color of the response color, and alternately output them to each other. Based on the output color values, various color wavelengths are emitted one by one, and an EEG responding to the subject is measured by the EEPROM 200.

The color we perceive is not the intrinsic color of the object, but the color of light that the object partially absorbs and partially reflects. For example, purple appears at 430 nm, green at 520 nm, yellow at 575 nm, and red at wavelengths of 650 nm. Visible light is a part of the electromagnetic spectrum and its wavelength ranges from 350 to 750 nm.

That is, the color is a phenomenon produced by a combination of light wavelengths of visible light spectrum. However, the color of a person who recognizes this color is not a physical characteristic inherent to a subject in a subjective sense, but a result created by an individual through his or her own eyes and the nervous system.

Therefore, even if the same object is seen, the perception of color may be slightly different depending on the person. However, there is no problem in communicating or exchanging information in everyday life, but there is a case where the color difference is different from that of a normal person beyond the difference of fine color recognition. The characteristic of color hue is that it can not recognize any color at all or distinguish it from other colors.

The RGB light emitting unit 110 emits light by dividing the primary color by the color wavelength, and the subject observes the color display panel 130 and measures the change of the EEG with respect to the changed color wavelength.

The selected comfortable colors and white color are displayed on the color display panel 130 for the same time each time. When the examinee views the color display panel 130 while the light is illuminated, the EEG 200 performs a secondary test do.

At the same time as the light illuminates, the EEG measurement program displayed when the color display panel 130 is viewed is operated to measure the EEG, and the light is turned off and the EEG program is terminated with the end of the test program.

That is, the RGB illumination light emitting region divides the wavelength range of 380 to 710 nm, which is a region of the visible light ray that can be perceived by a human being, by dividing each wavelength by a certain standard, and reads the target at the wavelength of the visible ray region, Lt; / RTI > The EEG value when the white light is emitted together with the region is also measured, and it is possible to measure the state value of the EEG together with each wavelength.

In addition, since the color of the right eye and the left eye may appear different from each other, the right eye and the left eye may be shielded separately for precise examination, or the binocular opening test may be performed.

When the brain wave is measured through the above-mentioned color vision test, the absolute value can be measured by theta, alpha, beta and gamma.

Calculate the amount of each of the theta, alpha, beta, and gamma with the measured absolute value as 100% as the relative value of the EEG when read in white light. In addition, the test time is divided into the middle half of the second half, and the EEG wave length is converted into a relative value in each time period.

These are listed by pre-, mid-, and late-hours, and the increase and decrease of EEG values over time are compared. EEG mapping is possible when EEG is multi-channel.

Electroencephalogram (EGG) is an electrical signal that is noninvasively measured by an electrode attached to the surface of the brain. The electrical activity of the brain reflected in brain waves is determined by neurons, gliacells, and blood-brain barrier, which are mainly caused by nerve cells.

Cetaphas are more prevalent in children than in adults, which usually appear in the process of emotional stability or sleep. Memory, psychic, creativity, concentration, anxiety, and so on. In this test, theta values are measured in terms of time, white light, and comfortable light, and the total amount is used to determine the brain condition of the subject, and the most favorable color is recommended.

The above values can apply the most favorable colors to a person and help to use brain energy more efficiently, thereby increasing the efficiency of life.

Beta values appear predominantly in the frontal lobe and appear during all conscious activities, such as when awake, when speaking. In an unstable state or in tension, it appears predominantly in complex computation processing. The beta value is the EEG that emerges from the focus. This value is used to determine the brain state of the subject with the total amount of change in white light and comfortable light over time, and recommends the most favorable color. With the above values, the most favorable colors can be applied to humans, and brain energy can be used more efficiently to increase the efficiency of life.

Delta waves appear predominantly in the deep sleep of a normal person or in a newborn.

Alpha waves appear mainly in relaxed conditions, such as relaxation, and the amplitude increases with more stable and relaxed conditions. In general, they appear continuously in the form of regular waves, with the greatest recorded in both genders and larynx and the smallest in frontal head. Especially when stable alpha waves appear, they close their eyes and are in a true state. When they open their eyes and look at an object, or become mentally excited, alpha waves are suppressed.

Gamma waves oscillate more rapidly than beta waves, and are reported to be more nervous in qualitative terms or to be highly related to cognitive information processing such as reasoning and judgment.

The amount of each of the theta, alpha, beta, and gamma stars is converted into a relative value with the entire measured absolute values of the wavelengths having the above characteristics as 100%.

Depending on the characteristics of each wavelength, theta value is an EEG that emerges when sleepy. In addition, beta waves and gamma waves are the brain waves that come out when you are learning and concentrating.

The illumination color information selected in accordance with the personal characteristics of the user is RGB illumination color information that can enhance the concentration or enhance the comfort to the user through the reading test and the EEG test as described above. The controller 420 may control the light emitting unit 410 of the illumination device 400 to select one of the plurality of illumination color information stored in the memory unit 430 One lighting device Even if multiple people use it as a common use, it is possible to provide a personalized color lighting that maximizes the individual's concentration.

For reference, the user terminal 300 preferably uses Bluetooth and Wi-Fi. This is because most devices support Bluetooth and Wi-Fi. The communication unit 310 of the user terminal 300 may include a MAC address (Media Access Control Address), an International Mobile Station Equipment Identity (IMEI), a User Device IDentification (UDID) And the universal unique identifier (UUID) to the memory unit 320 together with the illumination color information, and the controller 340 selects the illumination color information stored together with the unique identification information So that the illumination color of the LED light emitting unit 410 can be controlled on a user-by-user basis.

This is because the control unit 420 of the illumination device 400 confirms the unique identification information of the external device connected to the communication unit 440, i.e., the user terminal 300, It can be confirmed whether or not the RGB illumination device 400 based on the concentration-intensifying illumination system using the EEG is to be used. In other words, even if there is no user's request, once the user is stored, the user can confirm the RGB light color that can increase the concentration when the user intends to increase the concentration, and by illuminating the corresponding RGB color, Can be solved.

A MAC address (media access control) address is an address of a network device in the MAC layer in a network structure, and is usually stored in the ROM of the network card.

A User Device IDentification (UDID) is an identifier for identifying a user device. It is a kind of serial number.

A Universally Unique Identifier (UUID) is a 128-bit number used to identify an object or entity on the Internet. It is a nearly uniquely identifiable identifier made up of a combination of space and time (up to about 3400 years), and is used for a variety of purposes ranging from extremely short time objects to permanent object identification. There is no registration procedure for certification bodies, but only a unique identification number of the generic single identifier generation program is required. For example, storing a MAC address of a certain product in a specific server may cause a problem such as leakage of personal information, so that it can be used as an identifier for storing and storing a MAC address.

Various unique identification information (identifiers) have been described above, and one device can have a plurality of unique identification information.

For example, if the mobile phone is capable of Wi-Fi and Bluetooth communication, it has various unique identification information such as an identifier (UDID) of the mobile phone device itself, a MAC address for the Wi-Fi chip, and a MAC address for the Bluetooth chip.

In conclusion, the concentration-enhanced illumination system using EEG for color according to an embodiment of the present invention is further developed in an emotional LED capable of expressing various colors, An LED illumination device or an RGB illumination device can be provided.

When the control program is operated together with the result of the individual color wavelength in the illumination installed in the reading room, the office, the personal desk, the private office, the study room, etc., And it becomes possible to increase the concentration.

Also, in a relaxed mode, you can control your ALPHA to emit a high light color to increase your comfort.

Most of the subjects were able to confirm that the color wavelengths that they responded to were different.

In Table 1, the colors of the gamma-wave responding to each subject are listed. The wavelengths of the EEG waves are different in the time period between 10 and 40 seconds and 30 to 80 seconds, respectively. When you examine the right eye (Left), you can see that the EEG differs from the light color. The EEG showed high color intensity of gamma waves when compared to the wavelengths of white light, and it was confirmed that each subject had high concentration of color.

FIG. 4 is a flowchart illustrating a method of operating a concentration-enhanced illumination system using EEG for color according to the present invention.

As shown in FIG. 4, the method for operating the concentrated-intensity-enhanced lighting system using EEG for color according to the present invention emits RGB color wavelengths set for a preset time in the color tester 100 (S100). At this time, the RGB color wavelength is divided into arbitrary wavelength ranges, and the respective wavelengths are emitted by dividing predetermined wavelengths on a predetermined time basis.
