(Embodiment 1)
[Configuration example]
First, the structure of the lighting control system in this Embodiment is demonstrated using FIGS. 1-4.

  FIG. 1 is a block diagram illustrating a configuration example of a lighting control system according to an embodiment. Moreover, FIGS. 2-4 is a schematic diagram which shows the example of arrangement | positioning of the lighting control system in embodiment, respectively.

  The lighting control system of FIG. 1 includes a plurality of lighting fixtures 10, a plurality of detection devices 20, and a control device 30.

  Each of the plurality of lighting fixtures 10 performs spot illumination on the placement surface. For example, in FIG. 2, the luminaire 10 performs illumination with a spot in an illumination area 10 a including the entire table upper surface as a placement surface. The light distribution direction and the spot diameter of the spot irradiated with illumination can be changed within the illumination area 10a.

  The detection device 20 detects that an object has been moved from the outside of the placement surface onto the placement surface. In FIG. 2, the detection device 20 is installed on the ceiling of the store similarly to the lighting fixture 10. The detection area 20a of the detection device 20 is set wider than the illumination area 10a as shown in FIG. This is to detect the movement of the object from the outside to the inside of the placement surface (that is, the table or the like), or inside or outside. In FIG. 3, the object is a product placed on the upper surface of the counter stand for face-to-face sales and presented to the customer by the store clerk. In FIG. 4, it is a wine glass or a dish placed on a table. Although the perfume is illustrated in FIG. 3 as the product, for example, precious metal ornaments, jewelry, watches, food and drinks such as FIG. 4 and tableware (glass, dish, etc.) may be used.

  When it is detected that the object has been moved on the placement surface, the control device 30 controls the luminaire 10 to start spot illumination on the object. Thereby, even if the object is not on the display shelf, the appearance of the object is not deteriorated, and the appearance of the article can be further emphasized.

  For example, the control device 30 controls the luminaire 10 to gradually increase the illuminance after starting spot illumination. At this time, the control device 30 controls the direction and spot diameter of the spot illumination so that the approximate center of the spot illumination is aligned with the approximate center of the object. Thus, since the control apparatus 30 performs the illumination effect which raises illumination intensity gradually, it can make the appearance of articles | goods stand out without being conscious of illumination light.

[Configuration example of lighting equipment]
Next, the structural example of the lighting fixture 10 of FIG. 1 is demonstrated.

  Each of the plurality of lighting fixtures 10 includes a light source unit 110, a lighting circuit 111, a control circuit 112, a communication unit 113, a storage unit 114, a power supply circuit 115, and a light distribution control unit 116.

  The light source unit 110 includes one or more light emitting elements. The one or more light emitting elements are, for example, a plurality of LED (Light Emitting Diode) elements. Note that the one or more light emitting elements are not limited to LED elements. The light source unit 110 may include, for example, a semiconductor light emitting element such as a semiconductor laser, and a solid light emitting element such as an organic EL (Electro Luminescence) or an inorganic EL. The light source unit 110 may be a so-called downlight type capable of spot illumination.

  The lighting circuit 111 supplies the light source unit 110 with a voltage or current corresponding to lighting, blinking, extinguishing, etc. of the light source unit 110. When the light source unit 110 is a plurality of LED elements, this voltage or current varies depending on the illumination mode such as the dimming ratio and the toning ratio.

  The control circuit 112 controls the lighting circuit 111 corresponding to a plurality of illumination modes. The control circuit 112 performs control for realizing each of the plurality of functions of the lighting fixture 10. The plurality of functions include, for example, a dimming function for adjusting brightness, a toning function for adjusting color temperature, a fade function for adjusting brightness over time, and the like. The control circuit 112 follows the command received from the control device 30 via the communication unit 113.

  The communication unit 113 communicates with the control device 30. The communication unit 113 receives a command for instructing light adjustment, color adjustment, a direction of spot illumination, a spot diameter, and the like from the control device 30. Although FIG. 2 shows an example in which the communication unit 113 performs wired communication, wireless communication may be used.

  The storage unit 114 stores commands or data received by the communication unit 113.

  The power supply circuit 115 supplies power to each part in the lighting fixture 10.

  The light distribution control unit 116 controls the change of the light distribution direction and the spot diameter of the spot illumination by the luminaire 10. In the spot illumination, as shown in FIG. 2, the light distribution direction and the spot diameter are variable within the illumination area 10a. The light distribution control unit 116 follows the command received from the control device 30 via the communication unit 113.

[Example of detector configuration]
Next, a configuration example of the detection device 20 in FIG. 1 will be described.

  Each of the plurality of detection devices 20 includes a sensor 21, a motion detection unit 22, and a communication unit 23.

  The sensor 21 is, for example, a distance sensor or an image sensor. The sensor 21 as a distance sensor measures the distance to the placement surface. When the object is moved to the placement surface, the measurement distance changes. The distance sensor is, for example, a millimeter wave sensor, a PIR (Passive Infrared Ray) sensor, or the like.

  Moreover, the sensor 21 as an image sensor images a mounting surface. The image sensor is, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor, a CCD (Charge Coupled Device) image sensor, or the like. When the object is moved to the placement surface, the object on the placement surface is also imaged.

  The motion detection unit 22 detects the movement of the object based on the distance measured by the distance sensor. Alternatively, the motion detection unit 22 detects the movement of the object based on the image captured by the image sensor.

  When the sensor 21 is an image sensor, the motion detection unit 22 stores in advance feature data 22a indicating at least one of shape, size, and color as a feature of an article to be a target. The motion detection unit 22 can detect an article that matches the feature data 22a as an object. In this way, it is possible to prevent a malfunction when an article (for example, a pencil, a memo paper, an order form, a business card, etc.) that is not an object is placed on the placement surface.

  The communication unit 23 transmits the motion detection result by the motion detection unit 22 and the image of the image sensor to the control device 30.

[Configuration example of control device]
Next, a configuration example of the control device 30 in FIG. 1 will be described.

  The control device 30 includes a CPU 310, a memory 311, a communication unit 312, and an operation unit 313.

  The CPU 310 performs lighting control of spot illumination in the plurality of lighting fixtures 10 by executing a program stored in the memory 311.

  The memory 311 stores programs and data. The program stored in the memory 311 includes a lighting control program 31. The lighting control program 31 is a program for controlling spot illumination for making an object stand out with respect to the object detected by the motion detection unit 22. Data stored in the memory 311 is data in which the placement surface, the luminaire 10, and the detection device 20 are associated with each other. The mounting surface and the lighting fixture 10 may be one-to-one or one-to-many. The mounting surface and the detection device 20 may be one-to-one or may be many-to-one.

  The communication unit 312 receives the motion detection result from the communication unit 23 and notifies the CPU 310 of the motion detection result.

  The operation unit 313 receives a user operation related to lighting control.

[Operation]
The operation of the lighting control system according to the present embodiment configured as described above will be described below.

  FIG. 5 is a diagram illustrating a flowchart example of a lighting control process in the embodiment.

  In FIG. 5, when the motion detection unit 22 detects that an article has been moved from the outside of the placement surface onto the placement surface (yes in S51), whether or not the article matches the feature to be the object. If it is determined that the two objects coincide with each other (Yes in S52), it is detected via the communication unit 23 that the object has been moved from the outside of the placement surface to the placement surface. 30 is notified. The placement surface is a place on which an article is placed such as a table, counter, table, or the like as shown in FIGS. Note that step S52 may be omitted when the articles moving to the placement surface are limited.

  The control device 30 selects one or a plurality of lighting fixtures 10 that can spot-illuminate the mounting surface detected by the notified detection device 20 from the plurality of lighting fixtures 10 (S53), and the image of the image sensor. From this, the external shape, position, color, etc. of the object are discriminated (S54), and the illumination direction and the spot diameter are determined for each selected luminaire 10 (S55). Further, the control device 30 instructs the lighting direction and the spot diameter for each selected lighting fixture 10 to start spot lighting, and controls the lighting fixture 10 to gradually increase the illuminance (S56). At this time, the control device 30 may gradually narrow the spot diameter or may gradually change the color temperature. When an image sensor is not used as the sensor 21, S54 may be omitted.

  After the illuminance becomes sufficiently high, the control device 30 performs control so as to gradually change the illumination light for each lighting fixture (S57). In this control, for example, at least one of illuminance, color temperature, and spot illumination diameter is gradually and repeatedly changed. In addition, when there are a plurality of selected lighting fixtures 10, the control device 30 controls each of the plurality of lighting fixtures 10 so as to apply a plurality of spot lights to an object. At this time, the control device 30 may control each of the plurality of lighting fixtures 10 so that at least one of illuminance and color temperature is different from each other. In this way, it is possible to make the appearance of the object stand out and further change the appearance gradually. For example, if the target object is a precious metal, a jewel, an ornament or the like, not only the glittering appearance can be highlighted, but also the glittering feeling can be gradually changed.

  Simultaneously with the spot illumination in step S57, the detection device 20 determines whether the object has been moved on the placement surface (S58) and whether it has been moved out of the placement surface (S59).

  When the object moves on the placement surface and does not move to the outside of the placement surface (no in S59), the control device 30 determines the outer shape, position, color, and the like of the object from the image of the image sensor. The lighting direction and the spot diameter are determined for each selected lighting fixture 10 (S60), and step S57 is performed according to this determination.

  In addition, when the object has moved out of the placement surface (Yes in S59), the control device 30 gradually fades out the illuminance until the light is turned off for each selected lighting fixture 10 (S61).

  As described above, according to the lighting control system in the present embodiment, the appearance of an article can be further emphasized without deteriorating the appearance of the article even if the article is not on the display shelf.
