  Hereinafter, the best embodiment of the present application will be described with reference to the accompanying drawings. In addition, embodiment described below is embodiment at the time of applying the light emission pattern control apparatus of this application, etc. with respect to the light-emitting device.

  First, with reference to FIG. 1 etc., the structure and function of the light-emitting device which concerns on one Embodiment of this application are demonstrated.

  FIG. 1 is a diagram illustrating a schematic configuration example of a light emitting device according to the present embodiment. As shown in FIG. 1, the light emitting device S includes light emitting units 1a to 1c, a light emitting driver 2, a sensor 3 (an example of a state change detection unit), a control unit 4, and the like.

  Each of the light emitting units 1a to 1c includes, for example, a light emitting element (for example, LED), and one light emitting unit is in any of red, blue, and green colors under the control of the light emitting driver 2. It emits (variable) light. Moreover, the light emission parts 1a-1c are attached in the article mounting base.

  2A is a side view of the article mounting table, and FIG. 2B is a top view of the article mounting table. As shown in FIGS. 2A and 2B, the article mounting table 5 includes a circular article mounting plate 51 on which an article such as a container (for example, a plastic bottle) is placed, and a cylindrical table 52. It is configured. A cylindrical bar 53 is attached to the center of the cylindrical base 52, and the article placement plate 51 is attached to the cylindrical bar 53 so as to be rotatable with respect to the cylindrical base 52.

  Further, the article placement plate 51 and at least the upper plate 52a of the cylindrical base 52 are made of, for example, a transparent or translucent resin and transmit light. As a result, the light emitted from the light emitting units 1a to 1c attached at the positions shown in FIG. 2B in the cylindrical table 52 (on the lower surface side of the upper plate 52a) is converted into the upper plate 52a and the article placement plate. If the article passes through 51 and the article is placed on the article placing plate 51, the article is irradiated.

  The light emitting driver 2 supplies the drive current to the light emitting units 1a to 1c under the control of the control unit 4 so that the light emitting units 1a to 1c emit light in any one of red, blue, and green. It has become. For example, the light emitting unit 1a emits light in red, the light emitting unit 1b in blue, and the light emitting unit 1c in green. The light emitting driver 2 is mounted in the article mounting table 5.

  The sensor 3 detects a change in the state of the article, and detects rotation about the vertical axis of the article placed on the article placement plate 51 (that is, rotation of the article placement plate 51). A rotation detection sensor; and a pressure detection sensor that detects a pressure applied by an article placed on the article placement plate 51.

  The rotation detection sensor is provided, for example, in a gap between the article placement plate 51 and the upper plate 52a, detects when the article placement plate 51 rotates, and controls a signal indicating the rotation and the rotation direction. Output to part 4. Since various known techniques can be applied to the rotation detection sensor, detailed description is omitted. In the present embodiment, the article placement plate 51 is configured to be rotatable, but the article placement plate 51 is fixed without being rotatable, and the article placed on the article placement plate 51 is rotated. A rotation detection sensor that detects (a user turns an article) may be provided.

  The pressure detection sensor is a transparent sheet sensor, for example, and is formed in close contact with the upper surface of the article placement plate 51. That is, in this case, the article is placed on the pressure detection sensor on the article placement plate 51. In the press detection sensor, for example, the switches that are turned on by pressing are arranged in a matrix, and a signal indicating the on / off state of each switch is captured by the control unit 4. For example, the bottom of the container has irregularities, and a switch in contact with the convex portion on the bottom of the container is turned on by pressing the convex portion, and a signal indicating the on state is output to the control unit 4. In addition, you may comprise so that the weight detection sensor which detects the weight of articles | goods may be provided instead of a press detection sensor.

  The control unit 4 includes a CPU, a ROM, a RAM, a nonvolatile memory, and the like. For example, by executing a light emission pattern control processing program stored in the ROM, the information acquisition unit, the light emission pattern control unit, and the like of the present application are used. It functions, and controls the light emission pattern of the light irradiated with respect to the articles | goods mounted on the article mounting board 51. FIG.

  Specifically, the control unit 4 acquires information indicating a change in the state of the article from the sensor 3 and changes the light emission pattern according to the change in the state. Such a change in the state of the article is caused by an operation of handling the article by the user (for example, placing an article on the article placing plate 51, removing an article from the article placing plate 51, or on the article placing plate 51). Due to rotation of the mounted article or tilting of the article).

  For example, the control unit 4 acquires information indicating that an article has been placed on the article placement plate 51 by a signal from the press detection sensor (for example, each switch at a plurality of predetermined positions in the press detection sensor is turned on). If it is in the state, it is determined that the article is placed), and a control command is given to the light emitting driver 2 to change the light emission pattern before and after the article is placed.

  FIG. 3 is a diagram illustrating an example of a light emission pattern that changes between before and after the article is placed.

  FIG. 3A shows a light emission pattern before placing an article, that is, in a state in which signals indicating that all the switches in the pressure detection sensor are off are input from the pressure detection sensor to the control unit 4. The light emitting unit 1a emits red light, but the light emitting unit 1b and the light emitting unit 1c do not emit light (lights off).

  On the other hand, FIG. 3B shows that after the article is placed, that is, from the pressure detection sensor, a signal indicating that each switch at a plurality of predetermined positions in the pressure detection sensor is on is input to the control unit 4. The light emission pattern in a state (no signal from the rotation detection sensor) is shown. The light emitting unit 1a is red, the light emitting unit 1b is blue, and the light emitting unit 1c is green.

  When the article placed in this way is removed from the article placement plate 51, the control unit 4 displays information indicating that the article has been removed from the article placement plate 51 by a signal from the pressure detection sensor. By acquiring (for example, determining that the article has been removed if all the switches in the pressure detection sensor are in the OFF state) and giving a control command to the light emitting driver 2, before and after the article is removed. The light emission pattern is changed (from the light emission pattern of FIG. 3B to the light emission pattern of FIG. 3A).

  Moreover, the control part 4 acquires the information which shows the rotation and rotation direction of the articles | goods (article mounting board 51) mounted on the article mounting board 51 by the signal from a rotation detection sensor, and performs rotation of the said article. In response, the light emission pattern is changed by giving a control command to the light emission driver 2.

  FIG. 4 is a diagram illustrating an example of a light emission pattern that changes according to the rotation of the article.

  FIG. 4 (A) shows an input of a signal indicating that the switches at a plurality of predetermined positions in the pressure detection sensor are turned on before the rotation of the article, that is, from the pressure detection sensor to the control unit 4; A light emission pattern in a state where there is no input of a signal indicating that the rotation detection sensor is rotating and the rotation direction from the rotation detection sensor is shown. As in FIG. 3B, the light emission unit 1a is red. The light emitting unit 1b is blue, and the light emitting unit 1c is green, which emit light.

  On the other hand, FIG. 4 (B) shows that during rotation of the article, that is, there is an input of a signal indicating that each switch at a plurality of predetermined positions in the pressure detection sensor is in an ON state from the pressure detection sensor to the control unit 4. And the light emission pattern in the state with the input of the signal which shows that it is rotating and the direction of rotation (in this example, the right direction) from the rotation detection sensor is shown. The light emitting unit 1a emits light while changing the color from green → blue → red → ..., the light emitting unit 1b emits light while changing the color from red → green → blue → ..., and the light emitting unit 1c is blue → Light is emitted while changing the color from red to green. That is, in this example, as the article rotates in the right direction, each light emission color changes in the right rotation direction (for example, red light emission moves in the order of the light emitting unit 1a → the light emitting unit 1b → the light emitting unit 1c). To do. When the article is rotated in the left direction, the light emitting unit 1a emits light while changing the color from blue to green to red to... And the light emitting unit 1b is green to red. The light emitting unit 1c emits light while changing the color from red to blue to green, that is, each emission color changes in the left rotation direction (for example, red) The light emission proceeds in the order of the light emitting unit 1a → the light emitting unit 1c → the light emitting unit 1b).

  Further, the control unit 4 acquires information indicating that the article on the article placement plate 51 is tilted by a signal from the pressure detection sensor (for example, the article is normally (not tilted) on the article placement board 51). When the number of switches in the on state when it is mounted is reduced, it is determined that the article is tilted), and a control command is given to the light emitting driver 2 in accordance with the tilt of the article, whereby the light The light emission pattern is changed.

  FIG. 5 is a diagram illustrating an example of a light emission pattern that changes according to the inclination of the article.

  FIG. 5A shows a light emission pattern before the article is tilted. Like FIG. 3B, the light emitting unit 1a is red, the light emitting unit 1b is blue, and the light emitting unit 1c is green. is doing.

  On the other hand, FIG. 5B shows a switch (article mounting) at a predetermined position in the pressure detection sensor with respect to the control unit 4 from the pressure detection sensor to the control unit 4 while the article is tilted (inclined to the right in this example). The light emission pattern in a state where a signal indicating the on state is input to a part of the switches that are in the on state when the article is normally placed (not tilted) on the placing plate 51 is shown. The light emitting unit 1a emits light in red and the light emitting unit 1b emits in blue, but the light emitting unit 1c on the opposite side to the tilt side does not emit light (extinguishes). That is, in this example, the light emitting unit that emits light changes depending on the direction in which the article is inclined. For example, when the article is tilted to the left, the light emitting unit 1a emits light in red and the light emitting unit 1c emits green, but the light emitting unit 1b on the side opposite to the tilted side does not emit light.

  The control unit 4 may be attached inside the article placing table 5 or outside the article placing table 5.

  Next, a light emission pattern control process in the control unit 4 will be described with reference to FIG.

  FIG. 6 is a flowchart showing a light emission pattern control process in the control unit 4.

  The process shown in FIG. 6 is started when the light emitting device S is turned on. At the start of the process, the control unit 4 gives a control command to the light emitting driver 2 so that the light emitting unit 1a emits red light and the light emitting unit 1b and the light emitting unit 1c do not emit light.

  First, in step S1, the control unit 4 determines whether or not the state of the article has changed. For example, the determination is made based on whether or not the signal from the press detection sensor or the signal from the rotation detection sensor input to the control unit 4 has changed.

  Then, when there is a change in the state of the article (step S1: YES), the control unit 4 determines whether the change in the state is due to the placement of the article (that is, a predetermined plurality of positions in the press detection sensor). In step S2), if it is due to the placement of the article (step S2: YES), the process proceeds to step S3. If it is not due to placement (step S2: NO), the process proceeds to step S4.

  In step S3, for example, the control unit 4 changes the light emission pattern according to the placement of the control command (i.e., the light emitting unit 1a is red, the light emitting unit 1b is blue, and the light emitting unit 1c is green). Control command) is given to the light emitting driver 2, and the process returns to step S1. Thereby, the light emission pattern changes before and after the article is placed.

  In step S4, the control unit 4 determines whether or not the change in the state is due to removal of the article (that is, a signal indicating that all the switches in the pressure detection sensor are in the OFF state), and the article. If it is due to removal of the item (step S4: YES), the process proceeds to step S5. If not due to removal of the article (step S4: NO), the process proceeds to step S6.

  In step S5, for example, the control unit 4 gives a control command that causes the light emitting unit 1a to emit red light and does not cause the light emitting unit 1b and the light emitting unit 1c to emit light (that is, a control command to change the light emission pattern in accordance with the removal of the article). It gives to the light emission driver 2, and returns to step S1. Thereby, the light emission pattern changes before and after the article is removed.

  In step S6, the control unit 4 determines whether the change in the state is due to the rotation of the article (that is, a signal indicating that the switches at a plurality of predetermined positions in the pressure detection sensor are in the ON state is input and the rotation is performed. If it is due to the rotation of the article (step S6: YES), the process proceeds to step S7, and is not due to the rotation of the article. (Step S6: NO), it is determined that it is due to the inclination of the article, and the process proceeds to step S9.

  In step S7, for example, as described above, the control unit 4 controls each light emission color to change in the rotation direction in accordance with the rotation in the right direction or the left direction (that is, the light emission according to the rotation of the article). A control command for changing the pattern) is given to the light emitting driver 2. Thereby, the light emission pattern changes according to the rotation of the article.

  Next, the control unit 4 determines whether or not the state change due to the rotation of the article has ended (step S8), and when the state change has not ended (that is, the rotation is detected from the rotation detection sensor). If the signal indicating the rotation direction and the rotation direction continues to be input (step S8: NO), the process returns to step S7 to perform the same processing as described above, and when the change of the state is completed (step S8). : YES), the process returns to step S1.

  In step S9, for example, the control unit 4 causes the light emitting unit 1a to emit light in red, the light emitting unit 1b to emit light in blue, and the light emitting unit 1c on the side opposite to the inclination side of the article to emit light (that is, to the inclination of the article). In response, a control command for changing the light emission pattern) is given to the light emission driver 2, and the process returns to step S1. Thereby, the light emission pattern changes according to the inclination of the article.

  The above processing is repeatedly executed until the power of the light emitting device S is turned off, for example.

  As described above, according to the above embodiment, the control unit 4 is configured to acquire information indicating the change in the state of the article from the sensor 3 and change the light emission pattern according to the change in the state. Therefore, the lighting effect can be enhanced by changing the light emission pattern of the light applied to the article according to the movement of the article such as placement, removal, rotation, or tilting by the user. In addition, the user does not consciously operate the switch for changing the light emission pattern, but automatically changes the light emission pattern in the normal operation of handling the article, so that the atmosphere in the place without any sense of incongruity Can be changed. In particular, in the case where the article is a transparent or semi-transparent container (such as a plastic bottle or glass) and contains a drink, the user is healed more when the light emission pattern of the light changes. Etc. can be provided.

  In the above embodiment, the example in which the light emitting device S includes three light emitting units has been described, but four or more light emitting units may be included.

  Moreover, for example, the bottom shape (uneven pattern) of a container such as a plastic bottle is various. Therefore, for example, when the container is placed on the article placement plate 51, the control unit 4 acquires information on the shape of the bottom of the container, and determines the light emission pattern based on the information. It is more effective if it is determined as a means and configured to irradiate the article with light with the light emission pattern. In this case, for example, a distance measuring sensor for measuring the distance from the article placing plate 51 to the bottom of the container is provided, and more light emitting units (for example, several tens) are provided on one surface of the article placing plate 51, for example. Provide at intervals. And the control part 4 acquires the distance to each position in the bottom of the container measured by the distance measuring sensor as information on the shape of the bottom of the container, and for example, the position where the distance to the bottom is the shortest (for example, article mounting) A light emitting part close to the bottom (convex part) of the container in contact with the mounting plate 51 is determined, and a control command for causing the determined light emitting part to emit light is given to the light emitting driver 2. Thereby, light can be irradiated with the light emission pattern according to the shape of the bottom of the said container, and an illumination effect can be improved more.

  In the above embodiment, the light emitting device S and the article mounting table 5 may be provided and used in a vehicle interior, or may be provided and used in a restaurant, a bar, or the like.

  Moreover, in the said embodiment, although demonstrated taking the container as an example as articles | goods, for example, other articles | goods, such as a permeable object, may be sufficient.
