BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an autonomous smart light therapy system for relieving stress and improving working and learning efficiency.

The present invention relates to an autonomous intelligent light therapy system for relieving stress and improving working and learning efficiency. More particularly, the present invention relates to an autonomous intelligent light therapy system for relieving stress and improving work and learning efficiency. More particularly, Providing information of light healing contents close to the rhythm of nature to multiple LED lighting fixtures to illuminate the light most suitable for the user, thereby relieving stress and improving work and learning efficiency. To an intelligent light healing system.

Light Care has shown that red stimulates the sympathetic nervous system sympathetic nervous system and blue stimulates the parasympathetic nervous system, proving that light can act on the biochemical system to bring about the therapeutic effect.

At this time, the sympathetic nerve corresponds to the low frequency region of the 0.04 to 0.15 Hz band of the EEG, and is displayed high in a tense or excited state such as physical fatigue, energy loss in the body, insufficient sleep, and helplessness.

The parasympathetic nerve corresponds to the high frequency region of the 0.16-0.4 Hz band of EEG, and is low in anger, anxiety, and fear, such as mental and psychological fatigue, aging chronic stress, and the like.

These light healing plays an important role in physical and mental health, in the mood that simply improves the mood. Light and its energy are transmitted to the visual center, pineal gland, and hypothalamus through more than 100 million photoreceptors and optic nerves in the retina of the eye, affecting the secretion of brain hormones and neurotransmitters.

Table 1 summarizes the effects of light healing on the representative seven colors of light.

[Table 1]

Referring to Table 1, basically bright light causes hope, joy, comfort, comfort and light emotions, and dark light leads to depression, anxiety, irritability, fear, and somber emotions. At this time, red speeds up heartbeat, and green slows heartbeat, which is the physiological effect of so-called color. In addition, green has a psychological effect of giving a sense of calmness, red of passion, and blue of stability.

At this time, stress is a phenomenon that occurs in the emotional and psychological domains, but affects the physical domains.

It is reported that more than 70% of the diseases of modern people occur due to stress. In addition, 70% of stomach ulcers are due to stress, and they are caused by stress, alcoholism, allergy, tonsillitis, anxiety, arrhythmia, arthritis, bronchitis, caffeine addiction, colitis, depression, diarrhea, drug overdose, dyslexia, Gout, headache, malaise, schizophrenia, stress-related diseases and emphasizes the importance of stress care.

Excessive stress negatively affects all organs of our body and can cause all related diseases, so stress management on an individual level is very important.

Human-centered light-care contents (biorhythm) adapted to the biorhythm can alleviate human stress through the minute wavelengths of light transmitted to the brain waves, illumination colors, and illumination.

The relationship between stress and EEG was found to be generally higher in the stressed group than in the lower group, and the lowered mean value of the ALPHA in the red group was higher than that in the lower group. .

Up to now, the development of smart lighting technology has been actively carried out at home and abroad, but there has been no function as light care contents through recognition of the living body and the surrounding state of the user. That is, in the related art, only a technique for providing a user-controlled menu through a smart device and providing a lighting control function through the smart control device is mainly made up.

It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an autonomic intelligent light curing system for relieving stress and improving working and learning efficiency according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view illustrating an autonomous intelligent light curing system for relieving stress and improving work and learning efficiency according to an embodiment of the present invention. FIG. 6 is a block diagram illustrating an autonomous intelligent light healing system.

1 and 2, an autonomic intelligent light curing system 100 for relieving stress and improving work and learning efficiency according to an embodiment of the present invention includes a wearable smart device 120, a smart terminal 140, LED lighting fixture 160 and Zigbee 180. [

The wearable smart device 120 detects the user's heart rate, which is worn on the wearer's wrist and changes with respect to the stress stimulus, with the photo-current measurement sensor.

At this time, the user's heart rate is detected and measured by a photo-blood flow measuring sensor. Here, the optical blood flow measuring sensor irradiates an LED light source to a peripheral blood vessel, converts and analyzes the amount of absorption and reflection into a signal, and the absorption rate of light represents the maximum value of the heart rate systolic blood pressure as the minimum value of the diastolic blood pressure. As a result, it is possible to grasp the intensity of cardiac output, the elasticity of blood vessels, and the amount of residual blood, and the cumulative stress and external environmental resistance are analyzed as changes in pulse, and the relaxation state of sympathetic parasympathetic nerves and the balance of autonomic nerves . Therefore, the stress index is expressed by analyzing the microchannel change rate measured by the photorefractive blood flow sensor.

That is, by analyzing the Heart Rate Variability (HRV) through the optical blood flow measuring sensor built in the wearable smart device 120, the degree of stress for the light healing content information and the physical and mental stress .

At this time, HRV provides information for analyzing autonomic nervous activity from minute changes existing between beats and beats. In this way, the PPI (Peak to Peak Interval) of the optical blood flow measurement signal measured by the optical blood flow measuring sensor is an interval that changes according to the degree of stress. In the stress state, the PPI decreases because of the increased heart rate, The PPI tends to increase.

Particularly, in the present invention, by calculating the stress index by determining the season, time, weather, and temperature factors together with the heart rate of the user, the light intensity content information close to the rhythm of the nature along with the sun light is provided.

The smart terminal 140 is equipped with a global positioning system (GPS) function for wireless communication with the wearable smart device 120. The smart terminal 140 includes a storage unit 142, a determination unit 144, and a lighting signal generation unit 146.

The storage unit 142 stores stress indexes according to surrounding environment data including a predetermined heart rate and season, time, weather, and temperature.

For example, if an adult male of 18 to 25 years old has a heart rate of 70 to 73 bpm (beats per minute) and ambient data is in the summer, PM 01:00 to 02:00, clear and 15 to 20 ° C Stress Index-1 when stored at a stress index of 0, with a heart rate of 67 to 69 beats per minute and environmental data falling in the autumn, from 01:00 to 02:00, cloudy, and 9 to 14 ° C And may be stored as a stress index of 1 if the heart rate is 74 to 76 beats per minute and ambient data is in the summer, AM 10:00 to 11:00, clear and 15 to 20 ° C .

On the other hand, for women aged 26 to 35 years, the heart rate is 73 to 76 bpm. If the ambient data is in the summer, PM 01:00 ~ 02:00, clear and 15-20 ° C, The heart rate is 70 to 72 beats per minute and the ambient environment data is stored as the stress index -1 in the case of fall, PM 01:00 ~ 02:00, cloudy and 9 ~ 14 ° C, It can be stored as a stress index of 1 if beats per minute is 75 to 77 beats per minute and ambient data is in the summer, AM 10:00 to 11:00, clear and 15 to 20 ° C.

As a result, according to the embodiment of the present invention, the autonomic intelligent light curing system 100 for relieving stress and improving work and learning efficiency includes not only the heart rate of the user but also the heart rate, season, time, And provides light-healing contents information close to the rhythm of nature together with the sunlight to the plurality of LED lighting fixtures 160, thereby applying the light most suitable for the user, thereby relieving stress and improving work and learning efficiency Can be maximized.

At this time, the stress indexes may be set to 2001 grades from -1,000 to 1,000, but it is obvious that the grades can be changed into various grades.

The determination unit 144 receives the heart rate of the user measured by the optical blood flow measurement sensor and outputs a value corresponding to the stress index stored in the storage unit 142. That is, the determination unit 144 compares the heart rate of the user measured by the optical blood flow measurement sensor with the stress index stored in the storage unit 142, and determines the value corresponding to the stress index corresponding to the heart rate of the user .

The lighting signal generator 146 stores a plurality of lighting signals. The lighting signal generator 146 generates one lighting signal among the plurality of lighting signals in response to the value output from the determination unit 144. [ At this time, the plurality of lighting signals may be generated by applying the RGB and color temperature algorithm using the RGB color mixing theory. The plurality of turn-on signals may be set to light the LED lighting apparatus 160 at a color temperature of 3,000 to 9,000K and an illuminance of 5,00 to 70,000 lux. For example, when the stress index is 0, the lighting signal generator 146 stores a first lighting signal set to light the LED lighting fixture 160 at a color temperature of 5,000K and an illuminance of 1,000 lux, 1, a second lighting signal set to light up the LED lighting apparatus with a color temperature of 5,100K and an illuminance of 1,050lux may be stored.

The plurality of LED lighting apparatuses 160 are turned on at an illuminance and a color temperature set in accordance with the user's stress index in response to the lighting signal. At this time, the plurality of LED lighting devices 160 are installed indoors in at least one manner selected from a ceiling fixed type, a wall reflection type, a stand type, and a strip type.

The Zigbee 180 connects the smart terminal 140 and the plurality of LED lighting devices 160 by wireless communication. It is preferable that the ZigBee 180 uses a frequency range of 2400 to 2483.5 MHz.

In general, the cardiovascular center of the brain regulates heart rate through sympathetic nerves, parasympathetic nerves, and hormones in response to stress stimuli as well as physical activity changes. At this time, the sympathetic nerve is excited in the stressed state, and the parasympathetic nerve is activated in the relaxed state, thereby reducing the heart rate. As a result, the PPI of the PPG signal is decreased due to the increased heart rate in the stressed state, and the PPI is increased because the heart rate is decreased in the relaxed state.

Therefore, it is possible to judge whether or not the stress is caused based on the change of the PPI detected according to the change of the heart rate. The PPG sensor detects the heart rate that changes with respect to the stress stimulus and analyzes the heartbeat signal by appropriate signal processing to determine whether the user is stressed.

As shown in FIG. 3, the stress index is measured by detecting a user's heart rate with a photo-current measurement sensor. At this time, the optical blood flow measuring sensor irradiates the LED light source to the peripheral blood vessels, converts and analyzes the amount of absorption and reflection into a signal, and the absorption rate of light represents the maximum value of the systolic blood pressure as the minimum value of the diastolic blood pressure. As a result, it is possible to grasp the intensity of cardiac output, the elasticity of blood vessels, and the amount of residual blood, and the cumulative stress and external environmental resistance are analyzed as changes in pulse, and the relaxation state of sympathetic parasympathetic nerves and the balance of autonomic nerves . Therefore, the stress index is expressed by analyzing the microchannel change rate measured by the photorefractive blood flow sensor.

That is, by analyzing the heart rate variability (HRV) through the optical blood flow measurement sensor built in the wearable smart device, the degree of stress for the light healing content information and the physical and mental stress are indexed.

At this time, the microchannel change rate provides information for analyzing the activity of autonomic nerves from minute changes existing between beats and beats. In this way, the PPI (Peak to Peak Interval) of the optical blood flow measurement signal measured by the optical blood flow measuring sensor is an interval that changes according to the degree of stress. In the stress state, the PPI decreases because of the increased heart rate, The PPI tends to increase.

At this time, Table 2 summarizes the time watches.

[Table 2]

As shown in Table 2, the light-healing content information is adjusted according to the time-based bio-clock. At this time, basic light-healing contents information providing color temperature and illuminance, such as sunlight change according to the change of sunrise, sunset and midday time, is constituted.

In addition, it can be composed of soft glow-up like sunrise, majestic sunset function, lighting off function for sleeping time, calm dawn marine color function and forest color function through natural light effect function.

Meanwhile, FIG. 3 is a diagram showing summarized color pattern elements for each season.

As shown in FIG. 3, the light healing content information according to each season is based on the natural color, and there is a light color pattern that is familiar to humans and comfortable in the nature.

At this time, based on the user's stress, work, learning, and working conditions, the user perceives the external temperature and climate, time and date, and mixes appropriate color patterns to provide seasonal light-healing content information.

Table 3 shows the results of surveying color preference by age. At this time, Table 3 summarizes the results of the survey on the color preference of 100 Koreans of 20 ~ 34 years old, Japanese, and Chinese.

[Table 3]

As shown in Table 3, Koreans have strong preferences for white, blue, and black. On the other hand, the preference for pink and orange was stronger for Japanese people, and for red, orange and green ones for Chinese people. Therefore, it is preferable that the result of diagnosing the user's preferred color is reflected in the light-healing content information.

Table 4 shows the color temperature and the wavelength range for improving the efficiency in the task and learning areas, and FIG. 4 is a diagram showing the brain activity state and the wavelength generation range of the EEG.

[Table 4]

As shown in Table 4 and FIG. 4, light affects various fields such as brain waves, learning environment, and work environment for human beings. The learning efficiency is high when the human brain is in the most appropriate state, and the human brain is different in the part to be used depending on the color temperature, and the effect is large depending on the amount of light.

That is, the higher the color temperature, the greater the activity and concentration of the brain, and the lower the color temperature, the more active the emotion. Therefore, the effect on work or learning is the brain state where relatively low level brain waves such as Alpha and Ceta waves emit at the appropriate level to maximize the information throughput, memory and concentration of the brain.

For example, if the color temperature is transferred to the brain through the human vision, such as 6,000K in the basic living area and 3,000K in the rest time, activating the alpha wave and beta wave (beta) Can be determined.

Therefore, it is appropriate to provide the light and healing contents information in the work and learning mode, the rest mode, and the meal mode in consideration of the adaptation model of the color illuminance according to the weather and the season.

As described above, according to the embodiment of the present invention, the autonomous intelligent light-curing system for relieving stress and improving work and learning efficiency can determine the user's heart rate, the season, the time, the weather, By providing light information of the healing contents close to the rhythm of nature together with the sunlight to a plurality of LED lighting fixtures, it is possible to maximize work and learning efficiency by applying the light most suitable for the user, thereby relieving stress.

Accordingly, the autonomic intelligent light curing system for relieving stress and enhancing work and learning efficiency of the present invention can improve child development and concentration (ADHD, attention deficit hyperactivity disorder), and relieves stress and enhances work and learning efficiency But also the effect of preventing depression due to the stress of pregnant women.
