<Embodiment 1>
A first embodiment of the present invention is shown in FIG. First, the outline of the present embodiment will be described. This lighting system includes a plurality of light sources 11 by the lighting device 1, a sensor 2 that detects the presence of a person, and a lighting control device 3 that controls the lighting device 1. . When the lighting device 1 receives the control instruction from the lighting control device 3, the lighting device 1 performs lighting according to the received control instruction. When the sensor 2 detects the presence of a person, the sensor 2 transmits detection information including information regarding the position of the detected person and information regarding a direction in which the detected person's face is facing to the illumination control device 3. The illumination control device 3 includes an illumination determination unit 31. The illumination determination unit 31 determines the presence position of the detected person based on the information regarding the position in the detection information received from the sensor 2, and determines the illumination range corresponding to the presence position. In addition, the illumination determination unit 31 determines the direction in which the detected person is facing based on the information regarding the direction in the detection information, and the illumination range is illuminated from the front side with respect to the direction of the detected person's face. Control instruction is sent to the lighting device 1.

  Next, the illumination system of this embodiment will be specifically described.

  In the present embodiment, an illumination system is configured using a plurality of illumination devices 1 having a plurality of light sources 11. The light source 11 is preferably an LED, but may be other such as an incandescent bulb or a fluorescent lamp. In addition, you may comprise an illumination system by the one illuminating device 1 which has the several light source 11, and you may implement | achieve the several light source 11 by using two or more illuminating devices 1 which have the one light source 11. FIG. The plurality of light sources 11 are not installed in a concentrated manner, but are installed with a certain extent, and the plurality of light sources 11 as a whole can be positioned at an arbitrary position without changing the installation direction of the light sources 11. Can be illuminated.

  The sensor 2 detects the presence of a person. The sensor 2 transmits a radio wave, receives a radio wave reflected by a person or a wall, and detects the presence of a person from a change in the received radio wave. The sensor 2 may include an infrared detection unit and detect a person by detecting infrared rays emitted from the human body. Other methods such as detecting a person by image analysis or detecting a person by carrying an IC chip or the like and detecting a radio wave of the IC chip may be used. When the sensor 2 detects the presence of a person, the sensor 2 acquires information on the position of the detected person and information on the face direction of the person. Then, the sensor 2 transmits detection information including information regarding the position of the detected person and information regarding the direction in which the detected person's face is facing to the illumination control device 3.

  Regarding the acquisition of information related to the position, for example, when detecting the presence of a person by radio waves, a plurality of sensors 2 are provided in the lighting system, and are installed at separate locations. Then, each sensor 2 calculates the distance between the detected person and the self from the time taken for the radio wave to be reflected and returns, and uses it as information on the position of the detected person. In addition, it is good also as the information regarding the position of the detected person itself at the time of reciprocating. Further, any one of the sensors 2 may calculate the position of the detection target by combining the distances from the plurality of sensors 2 and may be information relating to the position of the person who has detected the position. The method for acquiring information about the position is not limited to this, and other methods such as image analysis may be used.

  In addition, regarding information on the face orientation, for example, it may be possible to determine the direction in which the face is facing using infrared rays by utilizing the fact that the surface temperature of a part not covered with hair such as the face is higher than others. It is done. In this case as well, as with the position, it may be information relating to the direction of the face of the person who detected the obtained data itself, or information indicating which direction the face is facing is obtained by analyzing the data. It may be information on the face orientation of the person who made it. The method for acquiring information related to the orientation of the face is not limited to this, and the information may be acquired by performing image analysis. Other methods may be used, such as a person carrying a device with an accelerometer or gyro sensor attached thereto, such as a mobile phone or a smartphone, and performing communication with those devices.

  Note that detection of the presence of a person, acquisition of information on a position, and acquisition of information on a direction may be performed by different methods, for example, the sensor 2 may be an image analyzer or the like, and all the information can be obtained only by this. You may make it perform acquisition. Further, for example, two methods may be used in combination, such as detecting the presence of a person by infrared detection and acquiring information related to a direction, and acquiring information related to a position using radio waves.

  The lighting control device 3 controls the lighting device 1. The illumination control device 3 includes an illumination determination unit 31 and a storage unit 311. The illumination determination unit 31 determines the presence position of the detected person based on the information regarding the position in the detection information received from the sensor 2, and determines the illumination range corresponding to the presence position. For example, when the distance from each of the plurality of sensors 2 to the detection target is received as information related to the position, the detected person's position is obtained by combining the information and the position of each sensor 2. to decide. Further, for example, when the position of the detected person is sent as information related to the position from the sensor 2, it is determined that the position is the position of the detected person.

  In addition, the illumination determination unit 31 determines the front side of the detected person by determining the direction in which the detected person is facing based on the information regarding the face orientation in the detection information. Regarding the determination of the direction, as in the case of the position, the illumination determination unit may analyze the data to determine the direction, or may determine the direction by authorizing the result of analysis by the sensor 2.

  And the illumination judgment part 31 sends a control instruction | indication with respect to the illuminating device 1 so that an illumination range may be illuminated from the front side of the detected person. The illumination determination unit 31 determines an illumination range corresponding to the detected position of the person according to the lighting control content stored in the storage unit 311. The illumination range is set to include the position of the detected person. FIG. 2 shows an example of the lighting control content of the storage unit 311. For example, it is assumed that the room is divided into areas as in the illuminable range table of FIG. The diagram on the right side of FIG. 2A is a view of a 4 m × 4 m room from above. The lower left corner of the room in the figure is the origin, the horizontal axis is X, and the vertical axis is Y. The unit is centimeter. Then, consider that the illumination range is set under conditions such as the lighting control content table of FIG. It is assumed that the angle at which the illumination range is illuminated is set, for example, from 45 ° diagonally forward left. At this time, if the sensor 2 detects a person at any point in the region 1, the illumination determination unit 31 refers to the table in FIGS. Extract the lighting control content. And the illumination range (radius 1m centering on a detection place) is determined from the lighting control content. The illumination determination unit 31 can illuminate the illumination range (radius 1 m centered on the detection location) from a predetermined angle (45 ° diagonally left forward) with a lighting method (spot) extracted for a person. 1 is extracted. In this extraction of lighting devices, a list of lighting devices 1 corresponding to detection positions, lighting ranges, angles, and the like may be stored in the storage unit 311 and the list may be referred to. Further, only the installation position of the lighting device 1 and the illuminable range of the lighting device 1 are stored in the storage unit 311 and calculated from the information, the detection position, and the position of the lighting range, and the appropriate lighting device 1 is extracted. May be. The angle may be set uniformly or may be set for each illumination range. Further, the illumination control content may include illuminance, illumination duration, and the like. The illumination determination unit 31 instructs the extracted illumination device 1 to illuminate the determined illumination range.

  The illumination control device 3 includes an input unit such as a remote controller or a switch, and performs illumination control according to the control content input from the input unit, such as lighting, extinction, dimming, or changing the illumination range and illumination angle. It may be.

Next, the operation of the illumination system configured as described above will be described using the flow shown in FIG.
First, the sensor 2 detects a person (step S1). When detecting the presence of a person, the sensor 2 acquires information regarding the position of the detected person and information regarding the direction in which the face is facing, and transmits the acquired information to the illumination control device 3 (step S2). When the lighting control device 3 receives the information about the position and the information about the direction in which the lighting control device 3 is facing, the lighting determining unit 31 determines the direction facing the detected person's position from the information. Then, the illumination determination unit 31 refers to the lighting control content of the storage unit 311 and determines the illumination range corresponding to the determined position. The illumination determination unit 31 extracts and determines the illumination angle, extracts the illumination device 1 that can illuminate the determined illumination range from the determined angle, and gives a control instruction to the illumination device 1 (step S3). Receiving the control instruction, the lighting device 1 controls the light source 11 according to the control content (step S4).

  Thus, the illumination system of this embodiment performs illumination according to the position of the person and the direction in which the person's face is facing. Since not only the illumination range but also the illumination direction relative to the face direction can be set, it is possible to perform illumination more in accordance with the user's desire. In the present embodiment, the front side of the face is set to a predetermined direction with respect to the face direction, and illumination is performed from the front side of the face. Therefore, it is difficult to see the screen by the illumination being reflected on the screen of the TV or personal computer. Can be reduced. In addition, if you are illuminating from the left front of the person when you are sitting at a table or desk, right-handed people will not be able to make a pen shadow on the writing surface when writing. I can expect. Furthermore, by setting the illumination range, it is possible to illuminate only a necessary place as compared to always illuminating the entire room, so that power consumption can be suppressed. If the duration of lighting is also set according to the position of the person or the illumination range, further reduction of power consumption can be expected. In addition, since illumination control is automatically performed using human detection as a trigger, it is possible to illuminate a required place without manual operation using a switch or the like.

  The lighting system may include a remote controller 5 that transmits a signal at an arbitrary timing according to a user's operation, and the remote controller 5 may detect a person.

  The remote controller 5 may include a lighting control content input unit, and may be a signal that can be transmitted with information on the control content that is input. For example, when a button is pressed, a radio wave or infrared light is emitted as a simple signal. It may be a thing. That is, other configurations and shapes are not limited as long as signals such as radio waves and infrared rays can be emitted at an arbitrary timing.

  When the remote controller 5 is used, the sensor 2 may determine that a person has been detected when receiving a signal from the remote controller 5, and does not require a configuration for actively detecting the presence of a person. The sensor 2 may be incorporated in the illumination control device 3 as a signal receiving unit from the remote controller 5. The operation after detecting a person by receiving a signal from the remote controller 5 is the same as described above. When the remote controller 5 is capable of acquiring the position information of the own apparatus, for example, by including a GPS receiver, the remote controller 5 transmits the position information of the own apparatus together with the signal, and the sensor 2 The information may be transmitted to the illumination control device 3 as information regarding the position of the detection target.

  Further, instead of the sensor 2 receiving a signal from the remote controller 5 to detect a person, the remote controller 5 itself may be used as the sensor 5. That is, for example, when a button on the remote controller 5 is pressed by the user, the remote controller 5 may detect a person and transmit information to the illumination control device 3 in the same manner as the sensor 2 described above.

  Thus, since this lighting system detects the presence of a person by receiving a signal from the remote controller 5 that is transmitted at an arbitrary timing, the lighting control can be performed only when necessary.

  In this embodiment, the detected person is illuminated from the front. However, the direction other than the front is stored in the storage unit 311 as the illumination angle, and the direction other than the front (the front side of the person) is stored. You may make it perform illumination.

<Embodiment 2>
A second embodiment of the present invention is shown in FIG. Since this illumination system has substantially the same configuration as that of the first embodiment, the description of the common configuration will be omitted, and only the characteristic configuration and operational effects will be described.

  The illumination system of the present embodiment includes a light detection sensor 4 that detects whether light has reached. At this time, the illumination control device 3 determines whether or not the light reaches the illumination range in which the control instruction is given to illuminate the illumination device 1 based on the information from the light detection sensor 4. The unit 32 is provided. If the light arrival determination unit 32 determines that the light does not reach the illumination range, the illumination determination unit 31 finely adjusts the irradiation angle within a predetermined direction with respect to the face direction.

  The light detection sensor 4 detects whether light reaches the target range. The light detection sensor 4 is, for example, an illuminance sensor. In this case, there are a plurality of light detection sensors 4 and detects the illuminance at the place where the device is installed. Then, the light detection sensor 4 transmits information regarding the illuminance to the light arrival determination unit 32. The light detection sensor 4 is not limited to an illuminance sensor, and may be an image sensor, for example. When the light detection sensor 4 is an image sensor, unlike the case of the illuminance sensor that detects the illuminance at the place where the device is installed, the light arrival situation of the place where light is desired to be detected Detect from.

  Based on the information transmitted from the light detection sensor 4, the light arrival determination unit 32 determines whether light has reached the illumination range in which the control instruction is given to illuminate the lighting device 1. For example, in the case where the light detection sensor 4 is an illuminance sensor, light is emitted from the illuminance of the light detection sensor 4 installed in the illumination range determined by the illumination determination unit 31 among the plurality of light detection sensors 4 to the illumination range. Determine whether has reached. In addition, you may judge not only whether the light has reached or not but how bright it is illuminated. In addition, as described above, the light arrival determination unit 32 may analyze the information from the light detection sensor 4 to determine whether the light has arrived, or the light detection sensor 4 may receive the light. The light arrival determination unit 32 may only recognize the determination.

  When the light determination unit 32 determines that the light does not reach the illumination range, the illumination determination unit 31 finely adjusts the irradiation angle in the range on the front side of the face, and the illumination range is detected by the person A control instruction is sent to the luminaire 1 so that it is illuminated from another angle on the front side. A plurality of angles may be set with priorities, and illumination is performed from an angle with a high priority. When the light arrival determination unit 32 also determines the brightness of the illumination range, the light arrival determination unit 32 or the illumination determination unit 31 also determines whether the brightness is insufficient. If the brightness is insufficient, the illumination determination The unit 31 instructs the lighting device 1 to make it brighter. At this time, the lighting device 1 that is currently lit may be instructed to increase the illuminance, or another lighting device 1 that can illuminate the illumination range may be instructed to be lit.

  FIG. 5 shows an operation flow of the illumination system after the illumination range is determined by the illumination determination unit 31 and a control instruction is given to the illumination device 1.

  First, light is detected by the light detection sensor 4 (step S101). Based on the information, the light arrival determination unit 32 determines whether light has reached the illumination range. If it is determined that the light has not arrived (No in step S102), the illumination determination unit 31 instructs the illumination device 1 to illuminate the illumination range from another angle (step S104). On the other hand, even when it is determined that the light reaches the illumination range (Yes in step S102), if the illumination intensity in the illumination range is insufficient (No in step S103), the illumination determination unit 31 The lighting device 1 is instructed to increase the illuminance of the range (step A105).

  As described above, when it is determined that the light does not reach the illumination range, the illumination system of the present embodiment automatically changes the illumination angle. Thereby, even if a shielding object exists, a predetermined position can be illuminated automatically.

<Embodiment 3>
3rd Embodiment of this invention is shown. Since this illumination system has substantially the same configuration as that of the first or second embodiment, the description of the common configuration will be omitted, and only the characteristic configuration and operational effects will be described. The configuration diagram is the same as FIG. 1 or FIG.

  In the illumination system of the present embodiment, when the illumination determination unit 31 determines that the detected person continues to exist at substantially the same existence position for a predetermined existence duration or longer, the existence position and the existence exist. A new illumination range set in advance corresponding to the duration time is determined. And the illumination judgment part 31 sends a control instruction | indication with respect to the illuminating device 1 so that this new illumination range may be illuminated.

  The lighting determination unit 31 issues a new lighting control command to the lighting device 1 based on the new lighting control content stored in the storage unit 311. The new lighting control content is set for a specific range of places, and the new lighting range and the original lighting range have been illuminated (that is, after a person has been detected), the new lighting range. And the time until the illumination range is illuminated. Each new illumination range is set corresponding to the original illumination range. Note that the new illumination range may be set corresponding to the detected position of the person, not the original illumination range. FIG. 6 shows an example of new lighting control contents. When the illumination determination unit 31 determines the illumination range, the illumination determination unit 31 refers to the new lighting control content in the storage unit 311. And when an illumination range corresponds to the place of this specific range, the illumination judgment part 31 measures the time when the detected person exists in the same place. At this time, if it is a certain amount of movement, the detected person may be regarded as being in the same place. When the time reaches the duration in the new lighting control content, the lighting determination unit 31 instructs the lighting device 1 to perform lighting for the new lighting range according to the new lighting control content. At this time, a new illumination range may be illuminated in addition to the current illumination range, or the current illumination range may be turned off and the new illumination range may be illuminated. It should be noted that a new illumination range may be set not for a specific range of locations but for all locations that can become the illumination range. A new illumination range is set by an input unit provided in the illumination control device 3. Moreover, when measuring the time when the detected person is in the same place, you may consider that it is not moving about short-distance movement.

  FIG. 7 shows an operation flow of the illumination system after the illumination range is determined by the illumination determination unit 31 and a control instruction is given to the illumination device 1.

  The lighting determination unit 31 refers to the new lighting control content, and when the detected person's place corresponds to the staying place in the new lighting control content (Yes in step S201), the person is staying at that place. Measure time. When the staying time reaches a time in the new lighting control content (Yes in step S202), the lighting determination unit 31 causes the lighting device 1 to illuminate a new lighting range in the new lighting control content. An instruction is given (step S203).

  Thus, the lighting system of the present embodiment illuminates a new illumination range when a person is present in the same place for a certain period of time or longer. Thereby, it can illuminate with the content according to the user's purpose more. It can be expected to be particularly effective when there are people in places where the purpose can be limited to some extent. For example, it is possible to illuminate the location of the lighting switch when standing at the entrance of the room, or to illuminate the periphery of the TV when sitting on a sofa in the living room.
