1 is a block diagram of a smart emotion lighting system.

Referring to FIG. 1, a smart emotion lighting system includes a user terminal 10 and a smart emotion lighting device 100.

The user terminal 10 may be a mobile terminal 11 or a wearable terminal 12 such as a smart clock or smart glasses depending on the type of the terminal used by the user. The user terminal 10 is preferably capable of network communication and capable of 3G / 4G network communication, Wi-Fi communication, Bluetooth communication, NFC communication, and the like. The user terminal 10 may include a GPS, a gyro sensor, a microphone, a camera, and the like. In the case of the wearable terminal 12, biometric information such as a user's heart rate can be obtained. It is also possible for the user terminal 10 to use the mobile terminal 11 and the wearable terminal 12 together.

Also, the user terminal 10 collects event information about the user and transmits the event information to the smart emotion lighting device 100, which will be described later. Here, the event information is used in a comprehensive meaning indicating the situation information inputted from the user such as the user's schedule, biorhythm, stress situation, and the like. For example, if the user is preparing for entrance, the test schedule can be input as event information. In addition, the user can input a personal situation through the user terminal 10, such as a user having a traffic accident or a fight. Also, the user terminal 10 can generate event information by recognizing the behavior pattern of the user using the location information.

Meanwhile, the user terminal 10 collects the user's biometric information and transmits it to the psychotherapy apparatus 100. Biometric information is signal information generated from the user's body such as heart rate, voice frequency, facial expression, and the like. For example, the heart rate of the user can be checked through the touch sensor of the user terminal 10, the voice frequency of the user can be confirmed through the microphone, and the change of the user's facial expression can be confirmed through the camera. The user terminal 10 can confirm the biometric information according to a preset time schedule or the occurrence of a user event.

Also, the user terminal 10 collects the user's emotion information and transmits the collected information to the smart emotion lighting apparatus 100. The emotion information indicates the emotion state of the user input from the user. For example, the user may enter emotions that the user feels while working with the customer at work in terms of positive or negative. The user terminal 10 can acquire the emotion information simultaneously with or at the same time as the biometric information, and receive the emotion information according to the predetermined time schedule or the occurrence of the user's event.

The smart emotion lighting apparatus 100 communicates with the user terminal 10 and outputs optimal LED illumination for lowering psychological stress by synthesizing user information including user's event information, biometric information, and emotion information. The smart emotion lighting device 100 generates a stress model for a user based on user information. Here, the stress model represents a stress scale including the user's stress intensity. The smart emotion lighting device 100 also controls the output of the LED illumination by matching a predetermined healing program for each stress model. Here, the healing program means a value that sets the output of the LED illumination for a situation in which the user's stress is lowered or concentration is required.

Hereinafter, the smart emotion lighting apparatus 100 will be described in detail with reference to FIG.

2 is a configuration diagram of a smart emotion lighting device according to the present invention.

2, the smart emotion lighting apparatus 100 according to the present invention includes an LED illumination unit 110, a communication unit 120, a user information obtaining unit 130, a stress model generating unit 140, and a control unit 150 .

The LED light 110 outputs various illuminations with RGB LEDs. The LED illumination 110 may be arranged by arranging a plurality of LEDs. The LED illumination unit 110 may control the blinking of a plurality of LEDs arranged to output a visible light signal. Also, the LED illumination 110 may display at least one of the symbols, characters, and graphics input from the user terminal by controlling blinking among the plurality of LEDs.

The communication unit 120 establishes network communication with the user terminal. For example, the communication unit 120 may use a wired / wireless network such as a Wi-Fi, a 3G / 4G network, a ZigBee, a WiBro, a Bluetooth, and a NFC (Near Field Communication). Also, the communication unit 120 may be a unidirectional communication or a bidirectional communication, and may be implemented by a module such as a beacon.

The user information obtaining unit 130 obtains user information including at least one of event information, biometric information, and emotion information from a user terminal. For example, the user information obtaining unit 130 may receive user's schedule, biorhythm, stress situation, and the like as event information, but the present invention is not limited thereto. Such event information is used as information for analyzing the current psychological state of the user in a situation where the user directly or indirectly recognizes the situation.

The user information obtaining unit 130 collects the user's biometric information from the user terminal, and the biometric information includes signal information generated from the user's body such as heart rate, voice frequency, facial expression, and the like. For example, the user information obtaining unit 130 can check the heart rate of the user through the touch sensor of the user terminal, check the voice frequency of the user through the microphone, and check the user's facial expression change through the camera . The user information obtaining unit 130 may receive biometric information from the user terminal according to a preset time schedule or a user event.

In addition, the user information obtaining unit 130 collects the user's emotion information from the user terminal, and the emotion information includes information of the emotion state of the user input from the user. For example, the user may enter emotions that the user feels while working with the customer at work in terms of positive or negative. The user information obtaining unit 130 may obtain emotion information from the user terminal at the same time or at the same time with the biometric information, and may receive the emotion information according to a preset time schedule or a user's event occurrence.

Hereinafter, the acquisition of biometric information and emotion information of a user through the user terminal will be described with reference to FIGS. 3 and 4. FIG.

FIG. 3 is an exemplary diagram for explaining that the smart emotion lighting device according to FIG. 2 acquires the user's biometric information through a user terminal.

Referring to FIG. 3, the user's heart rate, voice frequency, and facial expression change can be grasped through the user terminal 10. The heart rate can be acquired using a touch panel, a camera lens, a microphone, or the like formed on the user terminal 10. This is to find out whether the user shows a change in heart rate due to job stress. The voice frequency can be obtained by using the microphone of the user terminal 10. This is to determine whether the user shows a change in the voice frequency due to stress.

In addition, the change of the user's facial expression can be grasped through the camera of the user terminal 10. The purpose of this study is to grasp the stress on the forehead, eyebrows, eyes, eyes, mouth, and wrinkles. In this case, the facial photograph of the user can be automatically analyzed by the program installed in the user terminal 10, and the change of the facial expression according to the stress can be grasped.

It is also possible to provide a health check questionnaire through the user terminal 10 to receive the user's self-aware symptoms. For example, the user can enter symptoms of his / her own awareness, such as a stomach ache, a long bowel, a stomachache, a blinking eye, or a heavy head, as biometric information. In this case, it is also possible to grasp the stress information due to the subjective symptoms by grasping the user's disease information in advance. For example, a user who has a chronic disease of stress-induced enteritis may be given a weight on stress by inputting a situation such as a sore throat or diarrhea due to a subjective symptom.

4 is an exemplary diagram for explaining how the smart emotion lighting device according to FIG. 2 acquires emotion information of a user through a user terminal.

Referring to FIG. 4, the emotion information of the user can be inputted directly through the user terminal 10. For example, affirmative or negative emotion information may be displayed in the form of an icon or an emoticon through the screen of the user terminal 10, and the user may select an icon or emoticon corresponding to the emotion felt by the user. In this case, the emotion information can be divided into the positive information and the irregular information, and the emotion information can be further classified. In addition to the intuitive emotion expression of the user, the emotion information can also input his / her emotional state through a questionnaire.

Referring again to FIG. 1, the stress model generation unit 140 generates a stress model using user information. Here, the stress model is a model that diagnoses the psychological anxiety state felt by the user, and comprehensively judges stress intensity, cycle, and duration. The stress model can be updated when user information is input from a user terminal. The stress model is used as a reference data for setting an optimal healing program in the control unit 150 described later. The stress model generation unit 140 stores and manages a time-based stress model of the user in the DB.

Also, the stress model generation unit 140 may generate an average stress model, and generate a danger signal when generating a stress model having a deviation of more than the average value. This is to send a signal to the family, the emergency rescue center, etc. to inform the emergency if the user shows severe depression such as suicide. The stress model generation unit 140 is used as a reference data for matching a predetermined healing program in the control unit 150 described later.

The control unit 150 controls the output of the LED illumination unit 110 according to a predetermined healing program corresponding to the stress model. The healing program is set for each stress model and includes the color, color temperature, illuminance, intensity of the output of the LED light 110, and the flicker period, and may be changed depending on the user setting.

In addition, the control unit 150 may transmit the optical signal to the user terminal through the LED illumination unit 110. In this case, the LED illumination 110 may include a reference LED indicating whether the optical signal transmitted to the user terminal is valid or a data LED transmitting the binary data. The controller 150 may control the LED lighting 110 by selecting PWM (Pulse Width Modulation) dimming or analog dimming according to a preset time interval corresponding to the binary data.

The control unit 150 may control the output of the LED illumination unit 110 according to the proximity signal indicating that the user terminal is approaching within a predetermined distance or the release signal indicating that the user terminal is out of the predetermined distance have. In other words, even if the user does not turn on / off the power supply of the LED lighting 110, the control unit 150 turns on the LED lighting 110 according to the proximity information received from the user terminal, It is possible to turn off the LED illumination 110 according to the information.

Also, the control unit 150 may control the LED illumination unit 110 to output a notification display composed of symbols, characters, and graphics. The notification display indicates that a visual character signal is output from the user terminal according to the schedule of the user or the emotion of the user. For example, if the user has a test at 9 am, the letter "test" may be displayed on the LED light 110 before 9 am. Accordingly, the user can confirm his / her schedule through the identification mark formed on the LED illumination 110.

Meanwhile, the smart emotion lighting apparatus 100 according to another embodiment of the present invention may further include a speaker 111. The speaker 111 receives the sound source recorded in the user terminal through a network such as Bluetooth and outputs the sound source. The speaker 111 can output the sound source together with the LED illumination 110. [ The user can output the sound source stored in the user terminal even in the room. It is also possible to output a radio broadcast according to the user preference even when the user terminal is not stored.

Meanwhile, the smart emotion lighting apparatus 100 according to another embodiment of the present invention may further include an infrared light 112. The infrared light 112 is used for heating with light emitting in the air through near-infrared rays. The infrared light 112 is controlled by the control unit 150 and can be used with the LED light 110. In this case, the controller 150 controls the heating through the infrared light using the environmental information including the indoor or outdoor temperature and humidity and the user information. For example, on a rainy day, the infrared light 112 may be output at a predetermined time and intensity to increase the temperature inside the room. In addition, when the user is caught by a cold or a body temperature is lowered, the infrared light 112 can be controlled to be heated.

FIG. 5 is an exemplary view for explaining the types and arrangement of LED lights included in the smart emotion lighting device according to FIG.

Referring to FIG. 5, the LED illumination 510 includes a reference LED 510-1 and a data LED 510-2. The reference LED 510-1 may be located in the row or column direction of the data LED 510-2. Each reference LED 510-1 is a reference of the data LEDs 510-2 arranged in the row direction or the column direction. In FIG. 5, each of the reference LEDs 510-1 is a reference of eight data LEDs 510-2 arranged in the row direction. The reference LED 510-1 allows not only the lighting function but also the data valid at the user terminal to be confirmed. For example, if the reference LED 510-1 is on when the user terminal photographs an optical signal, the data transmitted by the associated data LED 510-2 can be processed as valid data. On the user terminal side, it is also possible to grasp the periods of lighting and lighting of the reference LED 510-1 and to effectively receive the optical signal of the data LED 510-2 for each period.

On the other hand, the data LED 510-2 serves to transmit data together with the illumination function. Each data LED 510-2 can represent binary data by turning on and off. In this case, even if the data LED 510-2 repeats blinking, since blinking can not be confirmed visually when the frequency exceeds a certain frequency, data can be transmitted without affecting the illumination function.

It is also possible to send one optical signal by using a plurality of data LEDs 510-2. For example, if eight data LEDs 510-2 are set as one signal unit, then two to ^eight data can be transmitted.

FIG. 6A is an exemplary view for explaining a current waveform of the LED illumination according to the time when PWM dimming and analog dimming are mixed in the smart emotion lighting apparatus according to FIG. 5, FIG. 6B is a diagram for explaining a current waveform corresponding to the current waveform according to FIG. 6A FIG. 8 is an exemplary diagram for explaining whether or not the recognized LED illumination is turned on.

Referring to FIG. 6A, the reference LED is basically controlled by the PWM dimming method and shows a constant pulse width and frequency. However, the timing may be set to be out of phase with the case of the PWM dimming method with the data LED. That is, in the period t1 in FIG. 6A, a period in which the reference LED indicates the current peak value Ip and a period in which the first data light source indicates the current peak value Ip are different from each other. The reference LED indicates the data validity of the data LED as described above. That is, the receiving side recognizes that the reference LED is lit only when the reference LED has the current peak value Ip. Therefore, it is determined that the data transmitted by the data LED at the moment when the reference LED is lit is valid.

Since the PWM dimming of the reference LED and the PWM dimming of the data LED do not coincide with each other, the optical signal of the data LED received in the state in which the reference LED is lit on the receiving side is recognized as being off. On the other hand, in the analog dimming method, the current peak value Ia of the light source is lower than that of the PWM dimming method, but is always recognized as being lighted on the receiving side. That is, the data light source dimmed by the analog dimming method in a state in which the reference LED is lit is always recognized as being lighted. Thus, when the data LED is dimmed by the PWM method on the basis of the lighting state of the reference LED, it is recognized that it is always turned off. When the data LED is dimmed by the analog method, it is recognized that the data LED is always turned on.

Accordingly, the controller 150 selects the PWM dimming method when the input binary data value is 0, and selects the analog dimming method when the binary data value is 1.

Referring to FIG. 6B, it is recognized that the reference LED, the first data light source, and the second data light source are all lighted in the time period from t1 to t5. This is because if the frequency at which the LED flashes exceeds a certain range, it can not be recognized visually. However, in the present invention, the PWM dimming method and the analog dimming method can be set so that the total light amount during a certain time period (t1, ..., t5) is the same. Therefore, when a signal is transmitted from a data LED, since the amount of light at each moment is the same, the difference between the binary data to be transmitted is 0 or 1.

On the other hand, the CCD photographed image of the user terminal can know that the data LED turns on or off every time interval. In the case of the first data light source, it is recognized as being off-lighting-off-lighting-on-off, which means dimming by PWM dimming at t1, t3 and t5 and dimming by analog method at t2 and t4. If the data is represented by binary data, the first data LED sequentially transmits data of 0-1-0-1-0, and the second data LED sequentially transmits data of 1-1-0-0-1. .

Accordingly, errors in data communication using a plurality of light sources can be reduced by synchronizing optical signal capturing timings on the user terminal side and obtaining an effective optical signal.

Fig. 7A is an exemplary view for explaining reception of a proximity signal from a user terminal in the smart emotion lighting apparatus according to Fig. 2, and Fig. 7B is a view for explaining reception of a departure signal from the user terminal in the smart emotion lighting apparatus according to Fig. Fig.

Referring to FIG. 7A, the smart emotion lighting apparatus 700 can output the ultrasonic waves 701 at predetermined time intervals. This is the unique identifying information of the smart emotion lighting device 700 that the user can not directly hear and can be identified through the user terminal. After the user terminal records the surrounding sound for a preset time and recognizes the identification information, the user terminal transmits the recognized information to the smart emotion lighting device 700, and a network is established between them. In this case, the smart emotion lighting device 700 judges the identification information recognition signal transmitted from the user terminal as proximity information. In other words, the smart emotion lighting device 700 recognizes that the user terminal is located within a predetermined distance from the smart emotion lighting device 700. [

Referring to FIG. 7B, the smart emotion lighting apparatus 700 determines whether or not a departure signal is received from the user terminal at a predetermined time interval. For example, when the identification pattern 702 of the user terminal is set to a predetermined departure signal, it is possible to determine movement of the user terminal by grasping the movement pattern information of the user terminal. For example, when the user terminal generates an identification pattern 702 that rotates from right to left in a circular pattern, the smart emotion lighting device 700 determines that the user terminal is a departure signal and turns off the power of the LED illumination, .

The smart emotion lighting device 700 may also include an infrared illumination 712 to control the output of the infrared illumination 712 according to the identification pattern 702 obtained from the user terminal. For example, if the user terminal generates an identification pattern 702 that rotates from right to left, the smart emotion lighting device 700 can turn off the infrared light 712 or set it to sleep mode.

FIG. 8 is an exemplary diagram for explaining outputting of the identification mark through the LED illumination in the smart emotion lighting device according to FIG. 2;

Referring to FIG. 8, the smart emotion lighting apparatus 800 outputs an identification display, which is composed of at least one of symbols, characters, and graphics generated from a user terminal or generated by a healing program, through an LED illumination. For example, if the schedule of the user acquired at the user terminal is set as '9am test (mid-term exam)', '7pm math school', '9pm science tutoring' If the user terminal is located close to the user terminal, the user can notify the user of the 'test' before 9:00 am according to the time schedule of the schedule.

Meanwhile, the embodiments of the present invention can be embodied as computer readable codes on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also a carrier wave (for example, transmission via the Internet) . In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner.
