The invention relates to medicine and can be used to provide a relaxing effect on the functional state of the person by light radiation from the led source.
Currently, there is a wide spread of new light sources based on light-emitting diodes. Such semiconductor light sources have not only incredibly powerful, but if they are built on the principle of RGB mixing) and the ability to vary the quality (color, range), quantitative (intensity) and modulation (frequency of outbreaks) light parameters for a given algorithm. This quality is called "intellectual light".
The closest in technical essence and the achieved result is a way to determine the impact on the functional state of a human light radiation (RU, patent No. 2217182. CL A61N 5/06. 2001).
The disadvantages of this method is the impossibility of providing a relaxing effect on the functional state of the person by light radiation.
The technical result, which directed the present invention, is the ability to provide a relaxing effect on the functional state of the person by light radiation from the led source.
Specified those who practical result is achieved by a method of providing a relaxing effect on the functional state of the person by light radiation from the led light source according to the invention the influence of white light with a color temperature of 1700 K and 10000 K carry out on the open eyes of the person, record the electroencephalogram, conduct its spectral analysis and increase the spectral power of the alpha rhythm by more than 50% of theta rhythm by more than 25% of the background values assess the impact of relaxing.
Conducted investigation of effects on the functional state of the human brain dynamically managed ("intellectual") of light from a semiconductor source with a color temperature varied in the range from warm 1700 K to cold 10000 K shades of white light.
Spectral analysis of EEG allowed to objectively evaluate changes in the basic rhythms of electrical activity in the brain when exposed to light with variable color temperature.
In the course of the study tested the prototype led mining light source controlled with the help of special software. The luminous flux of the light source depending on the color temperature was 1000-4000 LM. Color temperature of white light had changed and the mouth is establishing a range from warm 1700 K to cold 10000 K shades of white light. The color rendering index for these color temperatures lying in the range of 80-90.
During the exposure of white light with various color temperatures were recorded electrical brain activity of the subject.
The EEG recording was performed with an electroencephalograph "Telepathy-D" (, St. Petersburg) monopolar method according to the international system "10-20" points Fp1, Fp2, F3, F4, C3, C4, P3, P4, O1, O2, F7, F8, T3, T4, T5 and T6 by the indifferent electrodes placed on the earlobes. The sampling rate of the signals was 250 Hz, the bandwidth of the high frequency of 35 Hz, the time constant of 0.3 C.
As a control condition was used EEG with the eyes open. Next subject, remaining with open eyes, were subjected to sequential exposure to a variety of lighting options, different preset color temperature of the led source. The duration of recording in the background and samples with different illumination corresponded to 2 min in each case, the intervals between exposures of light also had a duration of 2 minutes
The study obtained data was carried out visually and by means of spectral analysis. Determined values of the spectral power of alpha, theta, Delta and beta rhythms in all recorded areas of the cerebral cortex at all stages referred to the registration of brain activity. Spectral analysis was carried out using electroencephalographic program WinEEG Version 1.3". Epoch analysis in the calculation of the spectra was 4 C. the Average spectral indices were calculated for the entire duration of recording in the background and EEG during exposure to light samples.
When statistical processing of obtained results was calculated the average values of the analyzed characteristics, their standard deviation, standard error of the mean. Determination of the degree of reliability of the differences between averages were performed in the statistical software package Statistica 6" at the level of p<0.05 using Wilcoxon criterion.
Visual analysis of EEG dynamics during expositions of white light with variable color temperature showed the presence of mixed reactions in the group examined in the light from the led source. In some cases there was a visible increase in the representation of the alpha rhythm and the strengthening of its regularity, which corresponds to an increase in the stability of the overall functional state of the brain. On the basis of the described type reaction was allocated a group of 10 people (3 women and 7 men) with preferential amplification of the alpha rhythm.
Spectral analysis of EEG allowed to objectively evaluate changes in the basic rhythms of electrical activity grown the th brain when exposed to light with variable color temperature. The group was characterized by a distinct increase in spectral power of alpha rhythm in the exposure light from 1700 K (p<0.05 in O1) and 10000 K (p<0.05 in Fp2, F4, P3, P4, O1, O2, T4, T6). In the latter case, these dynamics are captured more areas of the cortex. A small but significant increase in the power of theta rhythm was in F7 and T4 when light from 1700 K and F3, O1, F7, T4 10000 K (p<0.05). Under illumination with 3800 K 4800 K, 7000 K, the spectra in the range of alpha, theta and Delta rhythms were not significantly changed. Spectral characteristics of beta-rhythm remained unchanged in all samples.
The General character of the changes in EEG in subjects from the selected group shows relaxing exposed to light. It is known that increasing the severity of the alpha rhythm, also accompanied by increased slow activity, associated with a decrease in the level of activation in the brain, which contributes to a more proper rest and helps sleep.
Method of providing a relaxing effect on the functional state of the person by light radiation from the led light source is illustrated by examples.

SUBSTANCE: one should simultaneously register electroencephalogram (EEG) to detect the level of constant potential (LCP). At LCP negativization and increased EEG power one should detect depolarizational activation of neurons and enhanced metabolism. At LCP negativization and decreased EEG power - depolarized inhibition of neurons and metabolism suppression. At LCP positivation and increased EEG power - either repolarized or hyperpolarized activation of neurons and enhanced metabolism. At LCP positivation and decreased EEG power - hyperpolarized suppression of neurons and decreased metabolism of nervous tissue. The method enables to correctly detect therapeutic tactics due to simultaneous LCP and EEG registration that enables to differentiate transition from one functional and metabolic state into another.
