Description

The invention relates to lighting, and in particular to methods of controlling lighting, and can be used in everyday life and medicine to create lighting effects aimed at achieving highly effective psycho-emotional and psychophysical effects.

BACKGROUND OF THE INVENTION A METHOD FOR REGULATING THE COLOR OF AN LED LAMP WITH A PULSE POWER SUPPLY (CN 102869157) is known. The implementation of this method involves installing the controller in the control circuit of the LED lamp and connecting it to the power circuit. When turned on, the controller reads the last color value stored in memory and sets the required duty cycle of the pulse-width modulation circuits R, G and B, to change the color of the lamp, the controller changes the duty cycle in the R, G and B.

The disadvantage of this method is that it implements feedback with a person by manually changing the state of the controller, which sets the given color of the LED lamp, the prototype does not automatically change the color of the LED lamp depending on the psychophysical state of the person. The closest analogue in technical essence is the FLOWER MUSIC DEVICE (RF patent No. 2243810), consisting of an optical unit including light-emitting elements, an electronic unit and a control unit, which defines an algorithm for supplying control signals to light-emitting elements. During playback of the audio recording, the control signals of the control unit initiate the operation of the light-emitting elements according to a predetermined algorithm.

The disadvantage of the prototype is the low efficiency of psychophysical effects on humans, due to the lack of feedback from the device with the psychophysical state of a person.

The aim of the invention is to increase the effectiveness of the psychophysical effects of light on the human body.

The technical result consists in the fact that the invention provides automatic (semi-automatic) feedback of the lighting system with the psychophysical state of a person.

The technical result is achieved in that the method of controlling dynamic lighting, characterized by controlling the supply of voltage and / or commands that regulate the glow modes, by at least one lamp, differs in that at least a pair of sensors from the group are used: three-axis accelerometer, electronic compass, external thermometer, galvanic sensor, device for measuring human pressure, odor sensor, compression sensor, optical sensor, acoustic sensor, gyroscope; voltage is applied to the sensors used and the readings of the sensors are collected by wire or wireless method, which are then transmitted to the control processor or controller, where the incoming data from the sensors is processed and compared with previously entered standard indicators, and in the event of the deviation of the collected data from the sensors from the norm, voltage is controlled and / or regulatory modes of lamp illumination, changing their indicators until the moment when the collected data from the sensors comply with standard indicators, after which the voltage changes and / or control modes of the lamp are stopped until new deviations from the standard indicators; moreover, under the regulatory modes of illumination take: a change in lamp brightness and / or lamp temperature (K), and / or a change in the spectrum of the lamp.

Preferably, the voltage and / or control modes of the lamp are controlled via the Internet, through which data received from sensors is also transmitted; these data are recorded on a remote server, to which the sensors are connected directly or to which the collected data is transmitted from the sensors via a remote computer with access to the Internet.

Preferably, each of the sensors is configured to be mounted on or adjacent to the human body.

An interface 27 for presenting data of a sensor unit is paired with a network interface 24 in group 9 D2, also to the network interface 24 is connected the sensor unit 3 of group D1. The network interface 24 via the Internet communicates with a data processing server 30, which also communicates via the Internet with a network interface 31 configured to exchange data with the control unit 1.

The lighting control system implemented by the method can also be implemented using the device of FIG. 4 includes a control unit 1, which is connected to a lamp 4 configured to influence the psychophysical state of a person 34. The sensor unit of group D4 13 is configured to monitor the psychophysical state of a person 34 and is connected to a remote computer 36.

The sensor units (3, 6, 9, 11, 13) may include one, few or no sensors of the corresponding groups.

Sensors of groups D3 and D4, for example, can be built into a wristband, which can be configured to measure a person’s body temperature, and / or his pulse, and / or his pressure.

In the table. 2 shows possible combinations of using sensors.

Sensors that are not listed in the table. 2, can be used in the following combinations:

- the gyroscope can optionally be paired with a three-axis accelerometer (G-sensor);

- The electronic compass can optionally be used in conjunction with a three-axis accelerometer.

- an external thermometer, a galvanic sensor, a tonometer, an odor sensor and a compression force sensor all individually can be optional with all possible combinations of sensors.

The method is implemented as follows.

For all variants of implementation (Fig. 1-4) before use, sensors of groups D3 and D4 are installed on the human body.

According to one possible implementation option (Fig. 1), the sensor unit 6 registers the psychophysical state of a person 4 and presents the received information on the data presentation interface 7. The sensor unit 9 registers information about the human environment and presents it on the interface 8. The person manually enters information presented on interfaces 7 and 8, as well as other information about the current and desired psychophysical state, to data input interface 2, which transfers the entered information to control unit 1. Also, control unit 3 contains sensors 3 transmits information about the human environment. Depending on the values of the entered information, the control unit 1 changes the state of operation of the lamp 4, which affects the psychophysical state of a person 5. The operation of the device continues until the desired psychophysical state of the person is achieved.

According to another variation of the implementation (Fig. 2), the operation of the device is similar to the operation of the first embodiment of the device and differs from it in that the sensor unit 13 automatically transmits information about the psychophysical state of the person 15 to the control unit 1.

In another embodiment (Fig. 3), the operation of the device is similar to that of the previous embodiment and differs from it in that the sensor units 13 and 3 transmit data to the network interface 24. Information from the data presentation interfaces 26 and 27 and the desired psychophysical state entered into the network interface 24, which transmits the received data to the data processing server 30 via the Internet. Also, the data processing server 30 receives information about control commands from the control unit 1 through the network interface 31. The data processing server saves the received information to the appropriate database, analyzes it, and transmits information from the sensor units 13 to the control unit 1 through the network interface 31 3, data presentation interfaces 26 and 27, information on the desired psychophysical state of the person and additional control commands obtained as a result of the analysis. The control unit 1, depending on additional control commands, makes an appropriate adjustment to the method of controlling the lamp 4.

Another implementation example (Fig. 4) - the operation of the device is similar to the previous version and differs from it in that, instead of the network interface 24 (Fig. 3), a remote computer 36 is used. In the process of operation of the device, the data processing server 42 through the remote computer 36 can change the parameters and operating modes of the sensors of blocks 13 and 3 in order to optimize the management of the psychophysical state of a person.

On the example of the second implementation of the utility model (Fig. 2), we demonstrate the application of various options for combining the sensors presented in table. 2.

Option 1.

The sensor unit 13 includes an acoustic sensor, a thermometer and a galvanic sensor, which are placed on the human body to diagnose the psychophysical state of the person 15 and they transmit data on the heart rate, temperature and humidity of the body surface to the control unit 1. For example, the sensors can be placed in a wristband and transmit data wirelessly.

The sensor unit 3 contains an odor sensor, which transmits to the control unit 1 information about the presence of human pheromones in the ambient air.

The sensor unit 6 constitutes a tonometer and a compression sensor for the hand, which, in particular, can be used with a standard tonometer and expander. The data presentation interface 17 in this case is represented by the corresponding sensor scales, which display the values of the recorded parameters of blood pressure and compression force of the hand.

The sensor unit 9 is represented by an outdoor air thermometer, the temperature scale of which is the data presentation interface 18.

The control system implemented in control unit 1 operates according to the following scenarios.

The sensor unit 13 registers the change in the pulse and body temperature of the person, and transfer them to the control unit 1. According to these data, the control unit 1 determines the occupation of the person and his emotional state (active sport, surprise, emotional arousal). In accordance with the human condition, BU 1 changes the operating parameters of the lamp 15, namely:

- if BU 1 determined the nature of physical exertion, then for this kind of training, the red light at the beginning of the training is best suited to increase the heart rate, and in the process of training, the orange light is suitable;

- after physical exertion, if BU 1 determines calm, then it shifts the spectrum of the emitted light of lamp 13 to green in order to relax the nervous system and muscle tension;

- if BU 1 determined that a person is at rest during working hours or in the established mode for performing mental work, then he can change the temperature of white light to a colder one in order to increase the speed of performing tasks that require concentration, and also reduce the likelihood occurrence of errors due to increased concentration;

- if BU 1 determined that a person is at rest in the evening and not in a mode for performing mental work, then he can limit the level of the blue spectrum in the light in order to relax the person, it is possible to add green light to achieve the effect of concentration on thoughts and mental relaxation;

- if BU 1 determines that a person is at rest in the morning, then the lighting system can increase the level of the blue spectrum of light in order to charge a person with energy;

- if BU 1 determines that a person is at rest under established reading modes, then the color spectrum of lamp 13 of BU 1 changes to white, natural or slightly cold, in order to normalize eye strain and slightly relax the tension of the nervous system;

- if BU 1 detected an increase in temperature during physical exertion or an emotional outburst, then it turns on a cooler light so that the human nervous system feels a cooler environment.

The galvanic sensor in the sensor unit 13 can provide information about the level of moisture in the skin. In dynamics, you can get information about the intensity of perspiration of a person. Since each person reacts differently to different environmental temperatures depending on their nature of actions and / or emotional state, adjusting the lighting depending on this information can help prevent the occurrence of excessive levels of human skin moisture. This can be achieved through the use of lighting modes, which are aimed at calming the human nervous system and not increase the heartbeat.

The information received by the sensor unit 9, the ambient temperature is important information, because if the external environment is heated, then using the warm light of lamp 1 will make a person feel the heat, and cold light, on the contrary, will give a feeling of coolness. Together with a thermometer for measuring human body temperature - sensor unit 13, an external thermometer can also provide information about the heat exchange of the human body with the external environment, which allows you to take into account the intensity of lighting modes aimed at stimulating the heartbeat.

Periodically, a person using a blood pressure monitor, which is part of the sensor unit 6, measures blood pressure, takes his readings from the data presentation interface 17 and enters the interface 11, which transmits the blood pressure value to the control unit 1. An increase or decrease in the person’s pressure may indicate various emotional states. According to this information, BU 1 controls the lighting in order to correctly select the intensity of the lighting modes aimed at increasing the heartbeat, as well as to prevent a sharp decrease in pressure depending on the ambient pressure.

The odor sensor in the sensor unit 3 can be used to determine the hormonal phases of a person. Depending on the hormonal phases of a person, the lighting control system can regulate portions of blue and red spectra in lighting that have the greatest biological effect on a person’s physical condition.

Periodic measurement of the compression force of a human hand by an expander from the composition of the sensor unit 6 can provide information about human fatigue. Depending on this, a lighting mode can be selected that aims to reduce nervous tension or energize a person.

Option 2

If an optical sensor is added to the composition of the sensor unit 13, then it is additionally possible to measure the level of oxygen in the blood and the nature of the heartbeat, which allows BU 1 to more accurately determine the nature of human actions. Thus, it is possible to qualitatively separate states of active physical activity and emotional surprise or arousal. During physical exertion, information on the level of oxygen in the blood can correct lighting in order to increase or decrease the oxygen content in the blood due to the effect on the heart rate (for example, the transition from red or blue light to orange or green). In this embodiment, an additional benefit may be the separate arrangement of the acoustic and optical sensors on the human body (for example, on the finger and wrist or forearm). In this case, the measurement of heart rate and heartbeat can complement each other and provide more information about the load on the human body.

Option 3

The optical sensor can be used in conjunction with a thermometer as part of the sensor unit 13, which will measure body temperature, heart rate, the nature of the heartbeat and the level of oxygen in the blood. In this option, you can determine whether a person is engaged in active sports or is experiencing strong physical exertion, surprised, worried or emotionally excited. For this option, all scenarios that are used in options 1 and 2 can serve as an example of the implementation of lighting control scenarios.

Option 4

If only acoustic and optical sensors are used in the composition of the sensor unit 13, then the control unit 1 can determine the nature of a person’s physical load and his emotional state. In this option, the probability of erroneous determination of the state of a person increases, but, for example, the nature of physical activity can be determined with sufficiently high accuracy. This allows you to adapt the lighting exactly depending on the nature of the physical load with less consideration for its emotional state.

Option 5

When using a triaxial accelerometer in the sensor unit 13, it is possible to determine the nature of human movement. Namely, it is possible to determine whether a person is in a calm state, walks, runs, actively moves his arms or legs. Together with a thermometer for measuring the temperature of the human body, this allows you to determine the type of human action, which allows you to adjust the intensity of illumination of the lamp 13, which is best suited for walking, running, a static position or active actions in place.

Option 6

If a triaxial accelerometer, a thermometer, along with acoustic and optical sensors are used as part of the sensor unit 13, then BU 1 can determine the emotional state of a person, the type and nature of physical activity. Examples of scenarios for changing the nature of lighting are described in options 1-5. Additionally, you can track the dynamics of the pulse, the type of heartbeat and the oxygen content in the blood, depending on the type of human activity. This information is important for determining the level of fatigue of a person and his nervous system.

Option 7 and 8.

If a three-axis accelerometer, a thermometer, together with acoustic or optical sensors are used as part of the sensor unit 13, then the control unit 1 can determine the emotional state of a person, the type and nature of physical activity. In this embodiment, the composition of the sensors affects the accuracy of determining the state of a person. One of the additions to the options with a three-axis accelerometer can serve as a gyroscope. The gyroscope allows you to determine the orientation of the position of the human body. This, in turn, gives information about the position a person is in: standing, lying. For example, if a person lies and at the same time the nature of the pulse beats or the body temperature changes characteristic of a person who is falling asleep, then the lighting system can smoothly reduce the light intensity or turn it off.

Another addition to the options with a three-axis accelerometer can serve as a digital compass, which allows you to determine the change in the direction of movement of a person. For example, in this way it is possible to determine that a person is dancing, and depending on the frequency of the change in orientation, the intensity of lighting can be changed.

A useful effect of using the utility model is to provide a positive effect on the human body of various operating modes of the lamp 13, set by the control unit 1, with which you can tune the person to more productive work or relax him, soothe, establish a circadian rhythm, promote appetite, wake up and induce to sleep.
