(Embodiment 1)
With reference to Fig.1 (a)-FIG. 2, the illuminating device 1 which concerns on embodiment of this invention is demonstrated. FIG. 1A is a diagram illustrating the lighting device 1. As illustrated in FIG. 1A, the lighting device 1 includes a control unit 3, an object detection unit 5, and a light emitting unit 7. The lighting device 1 functions as, for example, a device that suppresses misplacement of an object.

  The light emitting unit 7 emits light. The light emitting unit 7 includes, for example, one or a plurality of light emitting elements. The light emitting element emits light, and is, for example, an LED (Light Emitting Diode).

  The object detection unit 5 detects whether an object is located at a predetermined location. For example, when the object is placed at a predetermined location, the object detection unit 5 detects that the object is positioned at the predetermined location. Moreover, the object detection part 5 detects that an object is not located in a predetermined location, for example, if an object leaves | separates from a predetermined location. The predetermined location indicates, for example, a placement surface of a placement unit such as a table on which an object is placed.

  Specifically, the object detection unit 5 detects a load received by the object detection unit 5 directly or indirectly from the object. The object detection unit 5 is, for example, a load sensor such as a load cell that detects a load, or a limit switch that detects a load via an actuator.

  Further, the object detection unit 5 outputs the first detection signal SG1 to the control unit 3. The first detection signal SG1 indicates whether or not the object is located at a predetermined location. Therefore, the control unit 3 can recognize whether or not the object is located at a predetermined location by the first detection signal SG1. The controller 3 can recognize, for example, that the object is placed at a predetermined location or that the object is separated from the predetermined location by the first detection signal SG1.

  In this specification, the object is, for example, baggage. Further, the object detection unit 5 detects, for example, baggage that is separated from a human hand. The baggage away from the human hand is, for example, baggage placed on a table. Therefore, for example, the lighting device 1 functions as a device that prevents misplacement of baggage in a toilet room.

  The control unit 3 controls the light emitting unit 7 based on the detection result of the object detection unit 5. Specifically, when the object detection unit 5 detects that an object is located at a predetermined location, the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 emits light according to the first light emission pattern PT1. To do. The first light emission pattern PT1 indicates that the light emitting unit 7 blinks and continues to be turned on in different periods. Further, control is performed so that the light emitting unit 7 is turned off when the object detecting unit 5 detects that the object is separated from the predetermined position during the period in which the light emitting unit 7 emits light according to the first light emission pattern PT1. The unit 3 controls the light emitting unit 7.

  Here, “flashing” indicates that the illuminance repeatedly fluctuates within a predetermined period. “Blinking” indicates, for example, that the illuminance repeatedly varies between the first illuminance value LV1 and the second illuminance value LV2 within a predetermined period. The second illuminance value LV2 is larger than the first illuminance value LV1. The first illuminance value LV1 is, for example, zero. The first illuminance value LV1 being zero indicates “off”. “Lighting” indicates that the illuminance is greater than zero. The “continuation of lighting” indicates that the illuminance does not fluctuate repeatedly within a predetermined period and does not include light extinction within the predetermined period. “Off” indicates that the illuminance is zero. “Continuation of lighting” typically indicates that the illuminance is constant within a predetermined period. “Lighting” indicates, for example, that the illuminance is the second illuminance value LV2 within a predetermined period.

  Next, the first light emission pattern PT1 will be described with reference to FIG. FIG. 1B is a diagram showing the first light emission pattern PT1. As shown in FIG. 1B, the first light emission pattern PT1 includes blinking of the light emitting unit 7 in the first period P1 and duration of lighting of the light emitting unit 7 in the second period P2. The second period P2 is a period subsequent to the first period P1.

  Specifically, when the object detection unit 5 detects that the object is located at a predetermined location at time t0, the control unit 3 switches the light emission unit 7 so that the light emission unit 7 blinks at the period T1 in the first period P1. Control. Next, the control unit 3 ends the blinking of the light emitting unit 7 and controls the light emitting unit 7 so that the light emitting unit 7 continues to be lit during the second period P2.

  Further, the control unit 3 controls the light emitting unit so that the light emitting unit 7 is turned off when the object detecting unit 5 detects that the object is separated from the predetermined position in either the first period P1 or the second period P2. 7 is controlled.

Therefore, since the object detection unit 5 detects an object, the light emitting unit 7 emits light according to the first light emission pattern PT1. As a result, it can be notified to the owner of the object by light that the object is placed at the predetermined location, and the misplacement of the object at the predetermined location can be suppressed.

  In particular, in the first embodiment, since the fact that the object is placed at a predetermined location is notified by light, the sound of the surrounding environment of the owner of the object (for example, broadcasting, music, or music appreciation by an earphone) is notified. It can suppress being influenced. As a result, misplacement of an object at a predetermined location can be effectively suppressed.

  In addition, in the first embodiment, the light emitting operation of the light emitting unit 7 is changed by executing blinking and lighting duration in different periods. Therefore, it is possible to effectively alert the owner of the object so as not to leave the object in comparison with the case where only the monotonous blinking is performed or the case where only the monotonous lighting is continued.

  According to the first embodiment, in the first light emission pattern PT1, the first period P1 is set before the second period P2. Therefore, flashing with a stronger stimulus than the duration of lighting is executed first. As a result, an effective stimulus can be immediately given to the owner of the object so as not to forget to place the object.

  Furthermore, according to the first embodiment, in the first light emission pattern PT1, the first period P1 is shorter than the second period P2. Therefore, the period of flashing with a stronger stimulus than the duration of lighting is shortened. As a result, it is possible to prevent the object owner from being obstructed from performing the job (for example, stool) by light stimulation.

  Further, according to the first embodiment, when the object detection unit 5 detects that the object is separated from the predetermined location, the light emitting unit 7 is turned off. Therefore, power consumption can be suppressed. Note that the fact that the object is separated from the predetermined location indicates that the possibility that the owner of the object has picked up the object from the predetermined location is high. Therefore, even if the light emitting unit 7 is turned off, the object is prevented from being left behind. Has been achieved.

  Furthermore, in Embodiment 1, it is preferable that the control part 3 controls the light emission part 7 so that 1st light emission pattern PT1 may be repeated. And it is preferable that the control part 3 controls the light emission part 7 so that the light emission part 7 will be light-extinguished when the object detection part 5 detects that the object was separated from the predetermined location.

  Therefore, according to the first embodiment, the first light emission pattern PT1 is repeated until the object moves away from the predetermined position, for example, until the owner of the object picks up the object from the predetermined position. Can be more effectively suppressed.

  Furthermore, in the first embodiment, when the object detection unit 5 detects that an object is located at a predetermined location, the light emitting unit 7 emits light according to any one of a plurality of different light emission patterns. In addition, it is preferable that the control unit 3 controls the light emitting unit 7. In the first embodiment, the plurality of light emission patterns include a first light emission pattern PT1, a second light emission pattern PT2, and a third light emission pattern PT3.

  Specifically, the second light emission pattern PT2 includes the duration of lighting of the light emitting unit 7 in the third period P3. And if the object detection part 5 detects that an object is located in a predetermined location at the time t0, the control part 3 will control the light emission part 7 so that the light emission part 7 may continue lighting in the 3rd period P3.

  As shown in FIG. 1D, when the selection information SL indicates the third light emission pattern PT3, when the object detection unit 5 detects an object, the control unit 3 performs the light emission unit 7 according to the third light emission pattern PT3. Controls the light emitting unit 7 so that the light is emitted.

  Specifically, the third light emission pattern PT3 includes blinking of the light emitting unit 7 in the fourth period P4. And if the object detection part 5 detects that an object is located in a predetermined location at the time t0, the control part 3 will control the light emission part 7 so that the light emission part 7 may blink by the period T2 in the 4th period P4.

  In any of the first period P1 to the fourth period P4, when the object detection unit 5 detects that the object is separated from the predetermined position, the control unit 3 is configured to turn off the light emission unit 7. 7 is controlled. Therefore, power consumption can be suppressed.

A desired light emission pattern can be selected from among the third light emission patterns PT3. As a result, the administrator can select an appropriate light emission pattern according to the surrounding environment of the lighting device 1.

  Moreover, according to Embodiment 1, the light emission part 7 can radiate | emit light according to the light emission pattern in any one of 1st light emission pattern PT1-3rd light emission pattern PT3. Therefore, it is possible to notify the owner of the object that the object is placed at a predetermined location with an appropriate light emission pattern according to the surrounding environment of the lighting device 1. As a result, the misplacement of the object at a predetermined location can be more effectively suppressed.

  Next, the control unit 3 will be described with reference to FIG. FIG. 2 is a diagram illustrating the control unit 3.

When the object detection unit 5 detects that the object is located at a predetermined location, the microcomputer 13 controls the lighting circuit 15 so as to emit light according to the light emission pattern indicated by the selection information SL from the input unit 9. The lighting circuit 15 supplies power to the light emitting unit 7 according to the control of the microcomputer 13. As a result, the light emitting unit 7 emits light according to the light emission pattern indicated by the selection information SL.

(Embodiment 2)
With reference to FIGS. 2-3 (d), 1 A of illuminating devices which concern on Embodiment 2 of this invention are demonstrated. The lighting device 1A according to the second embodiment is mainly different from the lighting device 1 according to the first embodiment in that a human detection unit 21 is provided. Hereinafter, the point that the illumination device 1A is different from the illumination device 1 will be mainly described.

  Fig.3 (a) is a figure which shows 1 A of illuminating devices. As illustrated in FIG. 3A, the lighting device 1 </ b> A includes a control unit 3, an object detection unit 5, a light emitting unit 7, and a human detection unit 21. The lighting device 1A functions as, for example, a device that suppresses misplacement of an object.

  The human detection unit 21 detects whether or not a person as a detected body has moved. The human detection unit 21 is, for example, a human sensor. A human sensor detects movement of a person or the like by detecting infrared rays emitted by the person or the like. In other words, the human detection unit 21 functions as a motion detection unit, and detects whether or not the detected object has moved. The detected object includes a person. The human detection unit 21 detects, for example, infrared rays radiated from the detection target and detects the movement of the detection target.

  Further, the human detection unit 21 outputs the second detection signal SG2 to the control unit 3. The second detection signal SG2 indicates whether or not a person as a detected object has moved. Therefore, the control part 3 can recognize whether the person as a to-be-detected body moved by 2nd detection signal SG2.

  The control unit 3 controls the light emitting unit 7 based on the detection result of the object detection unit 5 and the detection result of the human detection unit 21. Specifically, when the object detection unit 5 detects that an object is located at a predetermined location and the person detection unit 21 detects that a person has moved, the light emission unit 7 emits light according to the first light emission pattern PT1. The control unit 3 controls the light emitting unit 7 so as to emit light. Therefore, as long as the human detection unit 21 detects that the person has moved while the object detection unit 5 detects that the object is located at a predetermined location, the control unit 3 emits light according to the first light emission pattern PT1. Thus, the control of the light emitting unit 7 is repeated. For example, after the light emitting unit 7 finishes emitting light according to the first light emitting pattern PT1, as long as the object detecting unit 5 detects that the object is located at a predetermined location, When the detection part 21 detects again, the control part 3 controls the light emission part 7 so that light may be radiate | emitted according to 1st light emission pattern PT1.

  Further, control is performed so that the light emitting unit 7 is turned off when the object detecting unit 5 detects that the object is separated from the predetermined position during the period in which the light emitting unit 7 emits light according to the first light emission pattern PT1. The unit 3 controls the light emitting unit 7.

  Further, the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 blinks when the person detecting unit 21 detects that the person has moved during the period in which the light emitting unit 7 is kept on. It is preferable to do. For example, in this case, the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 blinks for a specific period.

  Next, the first light emission pattern PT1 will be described with reference to FIG. FIG. 3B is a diagram showing the first light emission pattern PT1. As shown in FIG. 3B, the timing of executing the first light emission pattern PT1 is different between the lighting device 1A and the lighting device 1.

  That is, the object detection unit 5 detects that the object is located at a predetermined location at time t0. And if the person detection part 21 detects that the person moved at time t1 after the time t0, the control part 3 will make the light emission part 7 blink so that the light emission part 7 blinks in the period T1 in the first period P1. Control. Next, the control unit 3 ends the blinking of the light emitting unit 7 and controls the light emitting unit 7 so that the light emitting unit 7 continues to be lit during the second period P2.

  As long as the object detection unit 5 detects that the object is located at a predetermined location after the second period P2 has elapsed, when the person detection unit 21 detects again that the person has moved, the first light emission pattern PT1 is followed. The control unit 3 controls the light emitting unit 7 so as to emit light.

  Further, the control unit 3 controls the light emitting unit so that the light emitting unit 7 is turned off when the object detecting unit 5 detects that the object is separated from the predetermined position in either the first period P1 or the second period P2. 7 is controlled.

  Furthermore, it is preferable that the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 blinks when the human detection unit 21 detects that the person has moved in the second period P2.

  As described above with reference to FIGS. 3 (a) and 3 (b), according to the second embodiment, for example, an object owner can complete an object (for example, a stool). When the object is placed at a predetermined location with the hand released, the object is positioned at the predetermined location. Therefore, the object detection unit 5 detects an object. Furthermore, when the owner of the object moves to start the job (for example, when sitting on the toilet seat), the person detection unit 21 detects the movement of the person who is the owner of the object. Accordingly, the light emitting unit 7 emits light according to the first light emission pattern PT1. As a result, it can be notified to the owner of the object by light that the object is placed at the predetermined location, and the misplacement of the object at the predetermined location can be suppressed.

  Further, according to the second embodiment, the object detection unit 5 continuously detects an object when the object remains placed at a predetermined location. Then, when the owner of the object moves after finishing the use (for example, when moving to stand up from the toilet seat and exit from the toilet room), the person detection unit 21 detects the movement of the person who is the owner of the object. . Accordingly, the light emitting unit 7 emits light again according to the first light emission pattern PT1. As a result, it can be notified to the owner of the object by light that the object remains placed at the predetermined location, and the misplacement of the object at the predetermined location can be effectively suppressed. In particular, since the notification by light after the completion of the required operation can be executed, misplacement of the object can be effectively suppressed. In addition, the second embodiment has the same effects as the first embodiment.

  Further, according to the second embodiment, even after the light emission according to the first light emission pattern PT1 is once finished, the object detection unit 5 detects that the object is located at a predetermined location, and the object owner As long as the person detection unit 21 detects that a certain person has moved, the light emitting unit 7 repeats emission of light according to the first light emission pattern PT1. Therefore, every time the owner of the object moves, it can be notified to the owner of the object by light that the object is placed at a predetermined location. As a result, the misplacement of the object at a predetermined location can be more effectively suppressed.

  Further, according to the second embodiment, when the person detecting unit 21 detects that a person has moved during a period in which the light emitting unit 7 is continuously lit (for example, the second period P2), the light emitting unit 7 Flashes. Therefore, for example, if the owner of the object moves after finishing the use while it is lit (for example, if it moves to stand up from the toilet seat and exit from the toilet room), the human detection unit 21 moves the object. Detects the movement of the person who is the owner. As a result, instead of the continuation of lighting, blinking with a stronger stimulus than that of the continuation of lighting is executed, and an effective stimulation can be immediately given to the owner of the object so as not to forget to place the object.

  As shown in FIG. 3C, when the selection information SL indicates the second light emission pattern PT2, the object detection unit 5 detects that the object is located at a predetermined location, and also indicates that the person has moved. When the human detection unit 21 detects, the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 emits light according to the second light emission pattern PT2.

  Specifically, the object detection unit 5 detects that the object is located at a predetermined location at time t0. And if the person detection part 21 detects that the person moved at the time t1 after the time t0, the light emission part 7 will be controlled so that the light emission part 7 will continue lighting in the 3rd period P3.

  After the elapse of the third period P3, as long as the object detection unit 5 detects that the object is located at a predetermined location, when the person detection unit 21 detects that the person has moved again, the second light emission pattern PT2 is followed. The control unit 3 controls the light emitting unit 7 so as to emit light.

  As shown in FIG. 3D, when the selection information SL indicates the third light emission pattern PT3, the object detection unit 5 detects that the object is located at a predetermined location, and also indicates that the person has moved. When the human detection unit 21 detects, the control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 emits light according to the third light emission pattern PT3.

(Embodiment 4)
Next, an illuminating device 1B according to Embodiment 4 of the present invention will be described with reference to FIGS. 7 (a) and 7 (b). The lighting device 1B according to the fourth embodiment is mainly different from the lighting device 1A according to the second embodiment in that the mounting device 30 is provided. The other configuration of the lighting device 1B is the same as that of the lighting device 1A. In the following, the difference between the fourth embodiment and the second embodiment will be mainly described.

  Fig.7 (a) is a perspective view which shows the illuminating device 1B. FIG.7 (b) is a top view which shows the internal structure of the illuminating device 1B. As shown in FIGS. 7A and 7B, the lighting device 1B includes a control unit 3, an object detection unit 5, a light emitting unit 7, a human detection unit 21, a placement unit 30, a housing, and a housing. A body 32 and a light source module 34 are provided. The light source module 34 includes a plurality of light emitting units 7 and emits light. The light source module 34 may include a single light emitting unit 7. In FIG. 7A, the controller 3 is omitted for simplification of the drawing.

  The lighting device 1B operates in the same manner as the lighting device 1A according to the second embodiment, and functions as, for example, a device that suppresses misplacement of an object. For example, the lighting device 1B is installed on the wall surface of a toilet room.

  Specifically, the housing 32 accommodates the control unit 3, the object detection unit 5, and the human detection unit 21. The placement unit 30 is installed on the top of the housing 32. In the fourth embodiment, the placement unit 30 is installed in the housing 32 so as to cover the upper opening of the housing 32. The placement unit 30 functions as a light guide plate. The mounting part 30 has a substantially flat plate shape, for example. The mounting unit 30 includes an incident surface 30a, a mounting surface 30b as a predetermined location, an end surface 30c, an end surface 30d, an end surface 30e, and a back surface 30f.

  The mounting unit 30 emits light from the mounting surface 30b serving as an output surface while guiding light incident from the incident surface 30a.

  Specifically, the incident surface 30 a faces the light emitting unit 7. That is, the light source module 34 is installed in the housing 32 so that the light emitting unit 7 faces the incident surface 30a. Accordingly, the light incident from the light emitting portion 7 is incident on the incident surface 30a. The incident surface 30 a constitutes one end surface of the placement unit 30. The light source module 34 is installed on the proximal end side of the housing 32, and the human detection unit 21 is installed on the distal end side of the housing 32.

  An object such as baggage is placed on the placement surface 30b. The placement surface 30b constitutes the front surface of the placement portion 30 and the back surface 30f. The mounting surface 30b emits light incident from the incident surface 30a. The mounting surface 30b may diffuse and emit light incident from the incident surface 30a, for example.

  Each of the end surface 30c to the end surface 30e may be blocked so as not to emit light incident from the incident surface 30a, or may emit light incident from the incident surface 30a. Note that each of the end surfaces 30c to 30e may diffuse and emit light incident from the incident surface 30a, for example. The back surface 30f may block the light incident from the incident surface 30a so as not to be emitted, or may emit light incident from the incident surface 30a. Note that the end face 30c and the end face 30e face each other, and the end face 30d and the incident face 30a face each other.

  The object detection unit 5 includes a plurality of elastic members 5a (two elastic members 5a in the fourth embodiment) and a limit switch 5b. The object detection unit 5 may include a single elastic member 5a. Each of the elastic members 5a has elasticity, and is, for example, a spring (for example, a coil spring or a leaf spring).

The limit switch 5b is turned on or off according to the operation of the actuator 6. The actuator 6 is in contact with the back surface 30 f of the placement unit 30.

  When the object is not placed on the placement surface 30b, the placement unit 30 is slightly lifted with respect to the housing 32 by the urging force of the elastic member 5a. Further, when the object is not placed on the placement surface 30b, the actuator 6 is not driven. Therefore, the limit switch 5b is off. In this case, the limit switch 5b outputs a first detection signal SG1 indicating that the object is not placed on the placement unit 30 to the control unit 3. As a result, the control unit 3 can recognize that the object is not placed on the placement unit 30.

  When the object is placed on the placement surface 30b, the placement part 30 sinks toward the housing 32 against the urging force of the elastic member 5a due to the load of the object. Therefore, the actuator 6 is driven (that is, the actuator 6 is pushed down), and the limit switch 5b is turned on. As a result, it is detected that the object is placed on the placement unit 30. In this case, the limit switch 5 b outputs a first detection signal SG <b> 1 indicating that the object is placed on the placement unit 30 to the control unit 3. As a result, the control unit 3 can recognize that the object is placed on the placement unit 30.

The control unit 3 controls the light emitting unit 7 so that the light emitting unit 7 emits light according to the first light emission pattern. As a result, light according to the first light emission pattern is emitted from the placement surface 30b.

  As described above with reference to FIG. 7A and FIG. 7B, according to the fourth embodiment, the placement unit 30 functions as a light guide plate, and thus the object is placed on the placement surface 30b. When the object detection unit 5 detects this and the person detection unit 21 detects that a person has moved, light according to the first light emission pattern is emitted from the placement unit 30. As a result, the misplacement of the object on the placement unit 30 can be effectively suppressed.

  In addition, since the lighting device 1B according to the fourth embodiment functions as the lighting device 1A according to the second embodiment, the lighting device 1B has the same effect as the second embodiment.

  The lighting device 1B can also function as the lighting device 1A according to the third embodiment. Therefore, the lighting device 1B according to the fourth embodiment can have the same effects as those of the third embodiment.

  The lighting device 1B can also function as the lighting device 1 according to the first embodiment. That is, the control unit 3 of the lighting device 1 </ b> B controls the light emitting unit 7 based on the detection result of the object detection unit 5. For example, as in the first embodiment, when the object detection unit 5 detects that an object is placed on the placement surface 30b as a predetermined location, the light emitting unit 7 emits light according to the first light emission pattern. In addition, the control unit 3 controls the light emitting unit 7. As a result, light according to the first light emission pattern is emitted from the placement surface 30b. When the lighting device 1B functions as the lighting device 1 according to the first embodiment, the lighting device 1B may not include the human detection unit 21. In addition, since the lighting device 1B according to the fourth embodiment functions as the lighting device 1 according to the first embodiment, the lighting device 1B can have the same effects as the first embodiment.
