[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that each of the embodiments described below shows a specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement and connection of the components, steps, order of steps, and the like shown in the following embodiments are merely examples and are not intended to limit the present disclosure.

[0012] Each figure is a schematic diagram and is not necessarily precisely illustrated. Therefore, for example, the scales and the like do not necessarily match in each figure. Furthermore, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated explanations are omitted or simplified.

[0013] (Embodiment) <Configuration and Function> Hereinafter, a lighting production system 1 according to an embodiment will be described with reference to FIGS.

[0014] Fig. 1 is a block diagram showing a lighting production system 1 according to an embodiment. Fig. 2 is a diagram showing a case where a first light is irradiated onto a first irradiation object and a second irradiation object, and a second light having a different color from the first light is irradiated onto the second irradiation object. Fig. 2 shows a case where the second light has a different color from the first light. Fig. 2 shows a case where the second irradiation object is a wall surface. This also applies to the figures following Fig. 2.

[0015] As shown in Figs. 1 and 2, the lighting production system 1 is installed in a store or a structure in the vicinity of the store. A store is a facility where an unspecified number of people visit to directly purchase goods, receive services, or use facilities. In this embodiment, a store installed in a facility is mainly exemplified. The facility is a building such as a building, a station, or a shopping center. Moreover, the structure in the vicinity of the store is a wall, floor, ceiling, etc. installed outside the store, that is, outside the room (outside the room), for installing the lighting production system 1.

[0016] In the lighting production system 1, a first light is irradiated onto a first irradiation object installed in a store, and a second light is irradiated onto at least one of a plurality of second irradiation objects including a floor, a wall, and a ceiling. In the lighting production system 1, an illumination state of the first light and the second light emitted from the lighting irradiation unit 11 is adjusted to produce an illumination that draws people's attention to the first irradiation object. In this embodiment, the first irradiation object and the second irradiation object may be collectively referred to simply as the irradiation object.

[0017] For example, in the lighting production system 1, the light that the lighting irradiation unit 11 irradiates on the irradiation object may include at least one of text information and image information. In this case, the lighting production system 1 can display at least one of text information and image information by the light that the lighting irradiation unit 11 irradiates on the irradiation object. In addition, the lighting production system 1 can be expected to make the first irradiation object stand out and attract people's attention by changing the brightness of the light and dynamically changing the color and pattern of the light.

[0018] The first irradiation object is provided on the second irradiation object and is an irradiation object onto which the first light is irradiated. The first irradiation object is, for example, a product installed in a store, a store symbol, or a product logo. The second irradiation object is an irradiation object onto which the second light is irradiated. For example, the second irradiation object is a structural body such as a floor, wall, or ceiling in a store.

[0019] As shown in FIGS. 1 and 2, the lighting production system 1 includes a lighting irradiation unit 11, a detection unit 12, a control unit 13, a storage unit 15, and a power supply unit .

[0020] The illumination irradiation unit 11 irradiates light onto at least a part of the floor, wall, and ceiling, and onto the commodity. In the present embodiment, the illumination irradiation unit 11 irradiates light onto at least a part of the floor, wall, and ceiling included in a plurality of second irradiation objects, while irradiating the first light onto the commodity included in the first irradiation object. Since the first irradiation object is provided in the second irradiation object, the illumination irradiation unit 11 can irradiate light not only onto the first irradiation object, but also onto the second irradiation object around the first irradiation object.

[0021] Specifically, the illumination irradiation unit 11 includes a first light source 11a that emits a first light and a second light source 11b that emits a second light. The illumination irradiation unit 11 can irradiate a first irradiation object with the first light and at the same time irradiate a second irradiation object that exists around the first irradiation object with the second light. The illumination irradiation unit 11 may include a plurality of first light sources 11a and a plurality of second light sources 11b. The first light source 11a and the second light source 11b may be separate and independent. The first light source 11a and the second light source 11b may be mounted on a single illumination irradiation unit 11.

[0022] The first light source 11a can irradiate the first irradiation object with the first light. The first light may not only illuminate the first irradiation object, but also illuminate a second irradiation object surrounding the first irradiation object. In other words, the first light can illuminate the first irradiation object and the second irradiation object that is the background of the first irradiation object. The first light source 11a may also emit the first light so as to illuminate only the first irradiation object.

[0023] The first light is white light. White light is light that includes an area showing the color category of "white" defined in a chromaticity diagram and an area of ​​a similar color category adjacent to the area showing the color category of "white". The brightness of the first light is set to be brighter than the range other than the irradiation range where the first light and the second light are irradiated.

[0024] The first light source 11a is turned on in a lighting mode according to a control signal obtained from the control unit 13. The first light source 11a can irradiate the first irradiation object with light of a constant brightness so as not to change the brightness. For this reason, the first light source 11a irradiates a static light (first light). The first light source 11a may have a dimming function and a color adjustment function.

[0025] The second light source 11b includes at least a part of the floor, the wall, and the ceiling, and is capable of irradiating the second light to the second irradiation object on which the first irradiation object is provided. The second light is different from the first light, and is irradiated to the second irradiation object existing around the first irradiation object. In other words, the second light can illuminate the second irradiation object existing around the first irradiation object.

[0026] The second light is at least one of light having a different color from the first light and light that changes dynamically.

[0027] For example, the color of the second light may be any color different from that of the first light. Specifically, the color of the second light may be a color in a region other than the region showing the "white" color category defined in the chromaticity diagram and the region of a similar color category adjacent to the region showing the "white" color category.

[0028] For example, the second light may be any light that changes dynamically. Specifically, the second light may be light in which at least one of the illumination aspects, such as a pattern, a figure, a character, a mark, brightness, a color tone, a shape (contour), a size, and an irradiation position, changes over time. In other words, the second light is a dynamic image, that is, a video.

[0029] The second light is not irradiated to the first irradiation object. Specifically, the second light illuminates the second irradiation object present around the first irradiation object so as to exclude the irradiation range of the first light irradiated to the first irradiation object. The second light may have a different color from the first light or may be dynamic light. For this reason, in order to make the first irradiation object stand out, it is preferable that the second light is not irradiated to the first irradiation object.

[0030] The brightness of the first light and the brightness of the second light are set to be brighter than the range other than the range illuminated by the first light and the second light, thereby making the range more noticeable than the range other than the range illuminated by the first light and the second light.

[0031] The second light source 11b is turned on in an illumination mode according to a control signal obtained from the control unit 13. The second light source 11b has a dimming function and a color adjustment function. The second light source 11b can adjust the dimming and color of the light to be irradiated to the second irradiation object based on the control signal from the control unit 13. For example, when adjusting the dimming and color, the second light source 11b can realize light that changes over time by changing the brightness, color tone, correlated color temperature, color rendering properties, contrast of shadows included in the light, and the like of the light to be irradiated to the second irradiation object.

[0032] For example, the second light source 11b can adjust the brightness of the emitted light in multiple steps as a dimming function, thereby making the brightness of the emitted light darker or brighter. Therefore, the second light source 11b can periodically fluctuate the brightness of the second light irradiated to the second irradiation object.

[0033] In addition, the second light source 11b can emit light with a low color temperature such as incandescent light and a high color temperature such as a clear sky as a color adjustment function. That is, the second light source 11b can periodically fluctuate the color tone of the emitted light. For example, the second light source 11b can periodically change the color temperature so as to repeatedly reduce the blueness of the emitted light and increase the redness, or reduce the redness and increase the blueness. Therefore, the second light source 11b can periodically change the color tone of the emitted light.

[0034] The first light source 11a and the second light source 11b are each formed of a light emitting module or the like. The light emitting module is an LED module in which a plurality of LED (Light Emitting Diode) elements are mounted. Each of the plurality of LED elements includes a red LED chip, a blue LED chip, and a green LED chip.

[0035] For example, the first light source 11a and the second light source 11b may be micro LEDs in which minute LEDs are arranged in a two-dimensional matrix. In the first light source 11a and the second light source 11b, the LEDs are regularly arranged in a matrix (two-dimensional array) of M rows and N columns. M and N are both natural numbers of 2 or more. M and N may be the same value or different values. In other words, the arrangement intervals in the row direction and column direction of the first light source 11a and the second light source 11b may be the same or different. In this embodiment, a case where the first light source 11a and the second light source 11b are micro LEDs is illustrated.

[0036] Moreover, the first light source 11a and the second light source 11b may be a spotlight equipped with a filter or the like, a downlight, a projector, or the like.

[0037] The detection unit 12 can detect the first irradiation object provided on the second irradiation object. Specifically, the detection unit 12 can detect the shape of the first irradiation object, the size of the first irradiation object, and the position of the first irradiation object. The detection unit 12 is, for example, an imaging unit such as a camera sensor, and an ultrasonic sensor. When the detection unit 12 detects the first irradiation object, it outputs the detected detection information to the control unit 13 and the storage unit 15. The detection information includes the shape of the first irradiation object, the size of the first irradiation object, and the position of the first irradiation object. The detection information, which is the result of the detection unit 12 detecting the first irradiation object, is stored in the storage unit 15.

[0038] The control unit 13 can control the first light source 11a and the second light source 11b based on the detection information, which is the result of detection by the detection unit 12. The control unit 13 can perform a performance in a predetermined illumination mode by controlling the first light source 11a and the second light source 11b based on the detection information. Specifically, the control unit 13 sets an illumination mode in which the first light source 11a and the second light source 11b irradiate the irradiation object based on the detection information, and controls the first light source 11a and the second light source 11b so that the irradiation object is illuminated in the set illumination mode. More specifically, the control unit 13 controls the first light source 11a and the second light source 11b so that the irradiation range and the irradiation position of the first light and the irradiation range and the irradiation position of the second light change based on the shape of the first irradiation object, the size of the first irradiation object, and the position of the first irradiation object detected by the detection unit 12.

[0039] This allows the control unit 13 to control the first light source 11a so that the first light is irradiated onto the first irradiation object and the second irradiation object that is the background of the first irradiation object. At this time, since the first lighting production information and detection information that realize the illumination mode of the first light are stored in the storage unit 15, the control unit 13 can control the first light source 11a so that the contour of the first light irradiated onto the second irradiation object becomes circular, polygonal, or the like, based on the first lighting production information and detection information stored in the storage unit 15. The first lighting production information includes information such as the brightness of the first light and the contour shape of the first light.

[0040] The control unit 13 can also control the first light source 11a so that the first light is irradiated only onto the first irradiation object.

[0041] In addition, since the second lighting production information and the detection information for realizing the lighting mode of the second light are stored in the storage unit 15, the control unit 13 can control the second light source 11b so as to change the second light produced on the second irradiation object over time, based on the second lighting production information and the detection information stored in the storage unit 15. The second lighting production information includes information indicating the brightness of the second light, the outline shape of the first light, the size of the first light, the outline shape of the second light, patterns, figures, characters, marks, brightness, color tone, shape (outline), size, irradiation position, etc.

[0042] The first lighting performance information and the second lighting performance information may be set in response to detection information, may be set in advance, or may be arbitrarily changed by a person. For this reason, a plurality of pieces of first lighting performance information and a plurality of pieces of second lighting performance information are stored in the storage unit 15.

[0043] Furthermore, when the first irradiation object moves, the control unit 13 can control the illumination irradiation unit 11 to follow the movement of the first irradiation object. Specifically, the control unit 13 can control to turn on a plurality of LEDs in the first light source 11a corresponding to the position of the first irradiation object based on the detection information, and a plurality of LEDs in the second light source 11b corresponding to the position of the second irradiation object excluding the irradiation range of the first light. As a result, some of the LEDs in the first light source 11a corresponding to the irradiation range of the first light are turned on, and some of the LEDs in the second light source 11b corresponding to the irradiation range of the second light are turned on.

[0044] The storage unit 15 stores first lighting performance information, second lighting performance information, detection information, and lighting information such as the position, irradiation direction, and performance of the lighting irradiation unit 11 for realizing the lighting mode. The storage unit 15 is realized by, for example, an HDD (Hard Disk Drive), but may also be realized by a semiconductor memory, and is not particularly limited and any known information storage means can be used.

[0045] The power supply unit 14 has a function of supplying power to the illumination irradiation unit 11, the detection unit 12, the control unit 13, etc. The power supply unit 14 is, for example, a power supply circuit in which a plurality of electronic components are mounted on a printed circuit board. The power supply unit 14 generates, for example, a driving power for making the illumination irradiation units 11 emit light. Specifically, the power supply unit 14 generates a driving power for making the illumination irradiation units 11 emit light, and supplies this driving power to each of the illumination irradiation units 11. This allows the illumination irradiation units 11 to emit light.

[0046] <Lighting aspect> Next, the illumination mode for an object to be illuminated will be described with reference to Figs. 3 to 9 and the like.

[0047] FIG. 3 is a diagram showing a case where the first light is irradiated onto the first and second irradiation objects, and the second irradiation object is irradiated with the second light having a pattern. FIG. 4 is a diagram showing a case where the first light is irradiated onto the first and second irradiation objects, and the second irradiation object is irradiated with the second light, which is a dynamic light. FIG. 5 is a diagram showing the contour of the first light irradiated onto the second irradiation object. FIG. 6 is a diagram showing a case where the first light is irradiated onto only the first irradiation object, and the second light is irradiated onto only the second irradiation object. FIG. 7 shows a case where a range where light is not irradiated is formed between the irradiation range of the first light and the irradiation range of the second light. FIG. 8 shows a case where light is not irradiated between the irradiation range of the first light and the irradiation range of the second light, and the irradiation range of the second light is formed around the irradiation range of the first light so as to be dotted. FIG. 9 is a diagram showing an illumination state of the first light and the second light when the first irradiation object moves.

[0048] As shown in Fig. 2 to Fig. 6, the control unit 13 can control the second light source 11b to cut out the irradiation range of the first light irradiated to the irradiation object using the outline shape of the first light and the size of the first light shown in the second lighting performance information, and irradiate the second light to the second irradiation object other than the cut-out range. That is, the second light source 11b can mask the irradiation range of the first light and emit the second light such that the shape of the second light irradiated to the second irradiation object is annular. Therefore, even if the first light and the second light are irradiated to the irradiation object, the first light and the second light do not overlap each other.

[0049] As shown in FIG. 3, the lighting production system 1 can irradiate a first illumination object and a second illumination object with white first light, cut out the illumination range of the first light, and irradiate a second light having a pattern on the second illumination object other than the illumination range of the first light.

[0050] As shown in FIG. 4, the lighting presentation system 1 can irradiate a first white light onto a first illumination object and a second illumination object, cut out the illumination range of the first light, and irradiate a second light onto the second illumination object outside the illumination range of the first light, creating an image of a moving vehicle.

[0051] As shown in FIG. 5, the control unit 13 can control the first light source 11a and the second light source 11b so that the contour of the first light irradiated onto the second irradiation object and the contour of the second light cut out have various shapes.

[0052] (a) of Figure 5 illustrates an example in which the contour of the first light irradiated onto the second irradiation object is circular, and in the irradiation range of the annular second light irradiated onto the second irradiation object, the inner contour with the central portion cut out is also circular.

[0053] (b) of Figure 5 illustrates an example in which the contour of the first light irradiated onto the second irradiation object is polygonal, and in the irradiation range of the annular second light irradiated onto the second irradiation object, the inner contour with the central portion cut out is also polygonal.

[0054] As shown in FIG. 6, the lighting production system 1 can irradiate white first light only onto a first illumination object, cut out the illumination range of the first light (only the range of the first illumination object), and irradiate second light onto a second illumination object other than the illumination range of the first light.

[0055] As shown in Fig. 7, the lighting production system 1 irradiates the first irradiation object and the second irradiation object with a white first light, cuts out the irradiation range of the first light, and irradiates the second irradiation object other than the irradiation range of the first light with the second light. In this case, a range where light is not irradiated may be formed between the irradiation range of the first light and the irradiation range of the second light. In other words, a part of the second irradiation object between the irradiation range of the first light irradiated on the irradiation object and the irradiation range of the second light may not be bright.

[0056] Furthermore, the maximum distance between the irradiation range of the first light and the irradiation range of the second light may be set based on the type of the first irradiation object and the distance from the first irradiation object to the person.

[0057] For example, if the first illumination object is a small item such as a ring, it is preferable for the distance to be 0.5 m or less when a person is in front of the first illumination object, it is preferable for the distance to be 1 m or less when a person is inside a store and away from the first illumination object, and it is preferable for the distance to be 2 m or less when a person is outside the store.

[0058] For example, if the first illumination object is a medium-sized product such as apparel, it is preferable for the distance to be 1 m or less when a person is in front of the first illumination object, it is preferable for the distance to be 2 m or less when a person is inside a store and away from the first illumination object, and it is also preferable for the distance to be 2 m or less when a person is outside the store.

[0059] For example, if the first illumination object is a large item such as a vehicle, it is preferable for the distance to be 1 m or less when a person is in front of the first illumination object, it is preferable for the distance to be 3 m or less when a person is inside a store and away from the first illumination object, and it is preferable for the distance to be 5 m or less when a person is outside the store.

[0060] As shown in Fig. 8, the lighting production system 1 irradiates the first irradiation object and the second irradiation object with a white first light, and irradiates the second irradiation object outside the irradiation range of the first light with a second light. In this case, the second irradiation object may be irradiated with the second light so as to move while being scattered around the irradiation range of the first light. In this case, a range where light is not irradiated may be formed between the irradiation range of the first light and the irradiation range of the second light.

[0061] As shown in FIG. 9, the lighting production system 1 can automatically adjust the first light to be irradiated onto the first illumination object and the second light to be irradiated around the first illumination object, even if the first illumination object moves.

[0062] When the state of Figure 9(a) is changed to the state of Figure 9(b) by moving the first irradiation object, the lighting production system 1 irradiates the first irradiation object and the second irradiation object with white first light to match the position of the moved first irradiation object, cuts out the irradiation range of the first light, and irradiates the second irradiation object outside the irradiation range of the first light with the second light.

[0063] In addition, while a large first illumination object is shown in (c) of Figure 9, when the size of the first illumination object changes from the state of (a) of Figure 9 to the state of (c) of Figure 9, the lighting production system 1 irradiates the first illumination object and the second illumination object with white first light to match the changed size of the first illumination object, cuts out the illumination range of the first light, and irradiates the second illumination object outside the illumination range of the first light with the second light.

[0064] Although not shown in the figure, if the shape of the first irradiation object changes, as described above, the lighting production system 1 irradiates the first irradiation object and the second irradiation object with white first light to match the changed shape of the first irradiation object, cuts out the irradiation range of the first light, and irradiates the second irradiation object outside the irradiation range of the first light with the second light.

[0065] <Example of operation> Next, with reference to FIG. 10, an example of the operation of the lighting production system 1 in this embodiment will be described.

[0066] FIG. 10 is a flowchart showing an example of the operation of the lighting production system 1 according to the embodiment.

[0067] First, the detection unit 12 detects the first irradiation object provided on the second irradiation object and acquires detection information (S11). When the detection unit 12 detects the first irradiation object and acquires the detection information, the detection unit 12 outputs the detection information to the control unit 13 and the storage unit 15. The detection information is stored in the storage unit 15.

[0068] Next, the control unit 13 controls the first light source 11a and the second light source 11b based on the detection information, which is the result of the detection by the detection unit 12 (S12). Specifically, the control unit 13 controls the first light source 11a based on the detection information so as to irradiate at least the first light onto the first irradiation object indicated in the detection information, and controls the second light source 11b so as to irradiate the second irradiation object indicated in the detection information with the second light.

[0069] Thus, by controlling the first light source 11a and the second light source 11b by the control unit 13, the first light source 11a can irradiate at least the first irradiation object with the white first light, cut out the irradiation range of the first light, and irradiate the second irradiation object other than the irradiation range of the first light with the second light. Then, the processing operation is completed.

[0070] <Variation 1> Next, the lighting production system 1 of this modified example will be described with reference to FIG.

[0071] Fig. 11 is a diagram showing the illumination state when a person notices the first illumination object. Fig. 11(a) shows a case where the person is not looking at the first illumination object, and Fig. 11(b) shows a case where the person is looking at the first illumination object.

[0072] In the following, since the configuration of the lighting production system 1 in this modified example is similar to the configuration shown in the embodiment, the configuration of the lighting production system 1 in this modified example will be given the same reference numerals and the description will be omitted as appropriate.

[0073] For example, a person's gaze on the first illumination object is considered to indicate that the person is interested in the first illumination object. For example, when a person stares at the first illumination object for a predetermined period of time, the person is considered to be interested in the first illumination object.

[0074] In this modification, the detection unit 12 can detect the line of sight of a person in a space and the first irradiation object. That is, the detection unit 12 can detect a person present in a space, the person's line of sight, and the first irradiation object. The detection unit 12 can also detect the position, size, shape, etc. of the first irradiation object. The detection unit 12 is, for example, an imaging unit such as a camera sensor, an infrared sensor, etc.

[0075] In this modification, when the detection unit 12 detects the line of sight of a person and the first irradiation object, the detection unit 12 outputs information indicating the detected line of sight of the person to the control unit 13. The information indicating the line of sight of the person is included in the detection information. In this modification, the information indicating the line of sight of the person may be referred to as the detection information.

[0076] The detection information may further include information indicating the field of view of the person detected by the detection unit 12, i.e., the field of view of the person. The detection unit 12 may estimate the field of view of the person by detecting the direction of the person's head or the person's eyes.

[0077] The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, which are the results of the detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, thereby enabling the production of a predetermined lighting mode.

[0078] Specifically, the control unit 13 sets the illumination mode of the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, and controls the first light source 11a and the second light source 11b so that the object is illuminated in the set illumination mode. More specifically, as shown in (a) and (b) of FIG. 11, when the detection unit 12 detects the line of sight of a person present in the space to the first irradiation object and the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the line of sight of the person to the first irradiation object detected by the detection unit 12 so that the state where the second light is irradiated to the second irradiation object changes to the state where the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object. As shown in (a) of Figure 11, when the detection unit 12 detects that the person's line of sight is not directed toward the first irradiation object, the control unit 13 controls only the second light source 11b so that the second light is irradiated to the second irradiation object.

[0079] <Variation 2> Next, the lighting production system 1 of this modified example will be described.

[0080] In the following, since the configuration of the lighting production system 1 in this modified example is similar to the configuration shown in the embodiment, the configuration of the lighting production system 1 in this modified example will be given the same reference numerals and the description will be omitted as appropriate.

[0081] In this modification, the detection unit 12 can detect the position of a person present in the space and the first irradiation object. That is, the detection unit 12 can detect a person present in the space and the position in the space where the person is present. The detection unit 12 is, for example, an imaging unit such as a camera sensor, an infrared sensor, etc. For example, the detection unit 12 detects the position of the person in the space and the first irradiation object, and detects the approach of the person to the first irradiation object from the change in the detected position. The approach of the person to the first irradiation object is considered to be a person showing an interest in the first irradiation object. For example, when a person approaches right next to the first irradiation object, it is considered that the person is showing an interest in the first irradiation object.

[0082] In this modification, when the detection unit 12 detects the position of the person and the first irradiation object, the detection unit 12 outputs information indicating the position of the detected person to the control unit 13. The information indicating the position of the person is included in the detection information. In this modification, the information indicating the position of the person may be referred to as the detection information.

[0083] The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, which are the results of the detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, thereby enabling the production of a predetermined lighting mode.

[0084] Specifically, the control unit 13 sets the illumination mode of the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, and controls the first light source 11a and the second light source 11b so that the object is illuminated in the set illumination mode. More specifically, when the detection unit 12 detects the approach of a person to the first irradiation object and the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the approach of the person to the first irradiation object detected by the detection unit 12 so that the state in which the second light is irradiated to the second irradiation object changes to a state in which the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object. When the detection unit 12 detects that the position of the person has not changed to approach the first irradiation object, the control unit 13 controls only the second light source 11b so that the second irradiation object is irradiated with the second light.

[0085] <Variation 3> Next, the lighting production system 1 of this modified example will be described.

[0086] In the following, since the configuration of the lighting production system 1 in this modified example is similar to the configuration shown in the embodiment, the configuration of the lighting production system 1 in this modified example will be given the same reference numerals and the description will be omitted as appropriate.

[0087] In this modified example, the detection unit 12 can detect the movement vector of a person present in the space and the first irradiation object. That is, the detection unit 12 can detect a person present in the space, the movement vector of the person, and the first irradiation object. The movement vector indicates the movement of a person present in the space moving from a predetermined reference point toward a predetermined direction, that is, the moving direction and the moving speed. In this embodiment, the movement vector is exemplified as the movement of a person present in the space moving from a predetermined reference point toward the first irradiation object. The detection unit 12 is, for example, an imaging unit such as a camera sensor, an infrared sensor, or the like. For example, the detection unit 12 detects the movement vector of the person and the first irradiation object, and detects the movement toward the first irradiation object from the detected movement vector. For example, when the movement vector of the person indicates a movement moving toward the first irradiation object at a high speed (brisk walking), it is considered that the person is interested in the first irradiation object.

[0088] In this modification, when the detection unit 12 detects the movement vector of the person and the first irradiation object, the detection unit 12 outputs information indicating the detected movement vector of the person to the control unit 13. The information indicating the movement vector of the person is included in the detection information. In this modification, the information indicating the movement vector of the person may be referred to as the detection information.

[0089] The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, which are the results of the detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, thereby enabling the production of a predetermined lighting mode.

[0090] Specifically, the control unit 13 sets the illumination mode of the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, and controls the first light source 11a and the second light source 11b so that the object is illuminated in the set illumination mode. More specifically, when the detection unit 12 detects a movement vector including a movement of a person present in the space moving toward the first irradiation object and the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the movement vector of the person detected by the detection unit 12 so that the state in which the second light is irradiated to the second irradiation object changes to a state in which the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object. When the detection unit 12 detects a movement vector in which the person is not moving toward the first irradiation object, the control unit 13 controls only the second light source 11b so that the second irradiation object is irradiated with the second light.

[0091] <Modification 4> Next, the lighting production system 1 of this modified example will be described.

[0092] In the following, since the configuration of the lighting production system 1 in this modified example is similar to the configuration shown in the embodiment, the configuration of the lighting production system 1 in this modified example will be given the same reference numerals and the description will be omitted as appropriate.

[0093] In this modified example, the detection unit 12 can detect the conversation content of people present in the space. Specifically, the detection unit 12 can detect the conversation content of people present in the space and detect (recognize) the content regarding the first irradiation object from the conversation content. The detection unit 12 is a voice recognition sensor or the like. For example, the detection unit 12 detects the conversation content of people and detects (recognizes) the content regarding the first irradiation object from the detected conversation content. The content regarding the first irradiation object is the conversation content showing interest in the first irradiation object. For example, when the conversation content of a person shows the first irradiation object, it is considered that the person shows interest in the first irradiation object.

[0094] In this modification, when the detection unit 12 detects the conversation content of a person present in a space, it outputs information indicating the conversation content of the detected person to the control unit 13. The information indicating the conversation content of the person is included in the detection information. In this modification, the information indicating the conversation content of the person may be referred to as detection information.

[0095] The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information, which is the result of detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information, thereby enabling the production of a predetermined lighting mode.

[0096] Specifically, the control unit 13 sets the illumination mode of the first light source 11a and the second light source 11b based on the detection information, and controls the first light source 11a and the second light source 11b so that the first light source 11a and the second light source 11b are illuminated in the set illumination mode. More specifically, when the detection unit 12 detects that the conversation content is about the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the conversation content about the first irradiation object detected by the detection unit 12 so that the state in which the second light is irradiated on the second irradiation object changes to a state in which the first light is irradiated on at least the first irradiation object and the second light is irradiated on the second irradiation object. When the detection unit 12 detects the conversation content other than the first irradiation object, the control unit 13 controls only the second light source 11b so that the second light is irradiated on the second irradiation object.

[0097] <Variation 5> Next, the lighting production system 1 of this modified example will be described.

[0098] In the following, since the configuration of the lighting production system 1 in this modified example is similar to the configuration shown in the embodiment, the configuration of the lighting production system 1 in this modified example will be given the same reference numerals and the description will be omitted as appropriate.

[0099] In this modified example, the detection unit 12 can detect the motion of a person present in the space and the first irradiation object. Specifically, the detection unit 12 can detect the motion of a person present in the space and detect that the motion is a motion toward the first irradiation object. The detection unit 12 is, for example, an imaging unit such as a camera sensor, an infrared sensor, or the like. For example, the detection unit 12 detects a person's gestures such as hand motion, head direction, and foot motion, and the first irradiation object, and detects a motion toward the first irradiation object from the detected gesture. The motion toward the first irradiation object is a motion that shows interest in the first irradiation object. For example, when a person's hand points to the first irradiation object, it is considered that the person is interested in the first irradiation object.

[0100] In this modification, when the detection unit 12 detects the motion of a person present in the space and the first irradiation object, the detection unit 12 outputs information indicating the detected motion of the person to the control unit 13. The information indicating the motion of the person is included in the detection information. In this modification, the information indicating the motion of the person may be referred to as the detection information.

[0101] The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, which are the results of the detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, thereby enabling the production of a predetermined lighting mode.

[0102] Specifically, the control unit 13 sets the illumination mode of the first light source 11a and the second light source 11b based on the detection information and the first irradiation object, and controls the first light source 11a and the second light source 11b so that the object is illuminated in the set illumination mode. More specifically, when the detection unit 12 detects the person's movement with respect to the first irradiation object and the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the person's movement with respect to the first irradiation object detected by the detection unit 12 so that the state in which the second light is irradiated to the second irradiation object changes to a state in which the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object. When the detection unit 12 detects the person's movement with respect to an object other than the first irradiation object, the control unit 13 controls only the second light source 11b so that the second light is irradiated to the second irradiation object. The person's movement with respect to an object other than the first irradiation object is an action showing interest in an object other than the first irradiation object.

[0103] <Action and effect> Next, the effects of the lighting presentation system 1 in this embodiment will be described.

[0104] As described above, the lighting production system 1 of the first aspect according to the present embodiment includes a first light source 11a capable of irradiating a first irradiation object with a first light, and a second light source 11b capable of irradiating a second irradiation object including at least a part of a floor, a wall, and a ceiling, on which the first irradiation object is provided, with a second light. The first light is different from the second light. The second light illuminates a second irradiation object present around the first irradiation object, and is at least one of light having a different color from the first light and light that changes dynamically.

[0105] According to this, by irradiating the first irradiation object with the first light and irradiating the second irradiation object around the first irradiation object with the second light, the light irradiated to the first irradiation object and the light irradiated to the second irradiation object can be separated, so that the first irradiation object can be made to stand out.

[0106] Therefore, the lighting presentation system 1 can enhance the visibility of a commodity, which is an example of a first illumination object. In particular, since the second light is at least one of light having a different color from the first light and light that changes dynamically, it is expected that the visibility of the first illumination object and the visibility of the surrounding second illumination object can be improved by the change of the second light relative to the first light.

[0107] For example, when the lighting production system 1 is applied to a store, it is expected to increase people's desire to buy.

[0108] A second aspect of the lighting production system 1 according to the present embodiment is the first aspect of the lighting production system 1. In this case, the first light is white light.

[0109] According to this, since the first illumination object is illuminated with white light, it is expected that the first illumination object will look the most attractive. In addition, the first light and the second light can be used to make the first illumination object stand out without giving an awkward feeling to the first illumination object.

[0110] The lighting production system 1 of the third aspect according to the present embodiment is the lighting production system 1 according to the first or second aspect. In this case, the first light source 11a and the second light source 11b are separate and independent. The first light source 11a irradiates the first irradiation object with the first light. The second light source 11b irradiates the second irradiation object present around the first irradiation object with the second light when the first light is irradiated to the first irradiation object.

[0111] This allows the first light source 11a and the second light source 11b to be arranged in separate locations, and therefore allows the irradiation directions of the first light and the second light to be irradiated onto the first irradiation object and the second irradiation object to be appropriately set.

[0112] Moreover, the lighting production system 1 of a fourth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to third aspects. In this case, the first light source 11a and the second light source 11b are mounted on a single lighting irradiation unit 11. The lighting irradiation unit 11 irradiates the first irradiation object with the first light and at the same time irradiates the second irradiation object present around the first irradiation object with the second light.

[0113] According to this, one illumination irradiation unit 11 equipped with the first light source 11a and the second light source 11b can be installed in a construction material, which makes the installation easy and saves space.

[0114] A lighting production system 1 according to a fifth aspect of the present embodiment is the lighting production system 1 according to any one of the first to fourth aspects. In this case, the first irradiation object is irradiated with a first light. The second irradiation object is irradiated with a second light. The second light illuminates a second irradiation object present around the first irradiation object so as to exclude an irradiation range of the first light irradiated on the first irradiation object.

[0115] According to this, the illumination range of the first light and the illumination range of the second light do not overlap, and therefore it is expected that an effect will be produced that is less likely to give people a sense of incongruity due to the overlap of the first light and the second light.

[0116] In addition, since the boundary between the illumination range of the first light and the illumination range of the second light becomes clear, it can be expected that the first illumination object will stand out more.

[0117] Moreover, the lighting production system 1 of a sixth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to fifth aspects. In this case, the second light is not irradiated onto the first irradiation object.

[0118] According to this, since the second light is at least one of light having a different color from the first light and light that changes dynamically, it is expected that when a person looks at the first illuminated object, the second light will not cause an awkward appearance of the first illuminated object.

[0119] The lighting production system 1 of the seventh aspect according to the present embodiment is the lighting production system 1 according to any one of the first to sixth aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects the shape of the first irradiation object, the size of the first irradiation object, and the position of the first irradiation object, and a control unit 13 that controls the first light source 11a and the second light source 11b based on the result of detection by the detection unit 12. The control unit 13 controls the first light source 11a and the second light source 11b so that the irradiation range and the irradiation position of the first light and the irradiation range and the irradiation position of the second light are changed based on the shape of the first irradiation object, the size of the first irradiation object, and the position of the first irradiation object detected by the detection unit 12.

[0120] According to this, since the detection unit 12 detects the shape, size, and position of the first irradiation object, even if the position of the first irradiation object is moved, the detection unit 12 can identify the first irradiation object after the movement. Therefore, the control unit 13 can automatically reset the illumination mode of the first light and the second light to be irradiated to the first irradiation object and the second irradiation object. Therefore, even if a person moves the first irradiation object, the person does not need to reset the lighting production system 1. As a result, it is possible to suppress an increase in the labor required for manual setting.

[0121] The lighting production system 1 of an eighth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to seventh aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects the line of sight of a person in a space, and a control unit 13 that controls the first light source 11a and the second light source 11b based on the result of detection by the detection unit 12. When the detection unit 12 detects the line of sight of a person present in the space toward the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the line of sight of the person toward the first irradiation object detected by the detection unit 12 so that the state in which the second light is irradiated to the second irradiation object changes to a state in which the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object.

[0122] According to this, by detecting the line of sight of a person, the detection unit 12 can irradiate the first light and the second light to the first irradiation object and the second irradiation object that are present in the field of view of the person. Therefore, it is expected that the attractiveness of the first irradiation object can be enhanced by further increasing the attractiveness of the first irradiation object.

[0123] In addition, in the case of a store, since light can be shone on the first illumination object that the store wishes to recommend to people, it is possible to reduce the need for additional staff in the store, which is expected to reduce the increase in fixed costs in store management.

[0124] The lighting production system 1 of a ninth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to eighth aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects the position of a person present in a space, and a control unit 13 that controls the first light source 11a and the second light source 11b based on the result of detection by the detection unit 12. When the detection unit 12 detects the approach of a person to the first irradiation object due to a change in the position of the person present in the space, the control unit 13 controls the first light source 11a and the second light source 11b based on the approach of the person to the first irradiation object detected by the detection unit 12 so that the state in which the second light is irradiated to the second irradiation object changes to a state in which the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object.

[0125] According to this, the detection unit 12 detects the position of a person, and thus it is possible to detect the approach of the person to the first irradiation object. When a person approaches the first irradiation object, the control unit 13 can irradiate the first irradiation object and the second irradiation object with the first light and the second light. Therefore, it is expected that the attractiveness of the first irradiation object will be highlighted by increasing the visibility of the first irradiation object to the approaching person.

[0126] The lighting production system 1 of a tenth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to ninth aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects a movement vector of a person present in a space, and a control unit 13 that controls the second light source 11b and the first light source 11a based on the result of detection by the detection unit 12. When the detection unit 12 detects a movement vector including a movement of a person present in a space moving toward a first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the movement vector of the person detected by the detection unit 12 so that the state where the second light is irradiated to the second irradiation object changes to a state where the first light is irradiated to at least the first irradiation object and the second light is irradiated to the second irradiation object.

[0127] According to this, the detection unit 12 detects the direction in which the person moves, and thus it is possible to detect the movement of the person moving toward the first irradiation object. When the person moves toward the first irradiation object, the control unit 13 can irradiate the first irradiation object and the second irradiation object with the first light and the second light. Therefore, it is expected that the attractiveness of the first irradiation object will be highlighted by increasing the attractiveness of the first irradiation object to the person moving toward the first irradiation object.

[0128] Moreover, the lighting production system 1 of an eleventh aspect according to the present embodiment is the lighting production system 1 according to any one of the first to tenth aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects the contents of a conversation between people present in a space, and a control unit 13 that controls the first light source 11a and the second light source 11b based on the result of detection by the detection unit 12. When the detection unit 12 detects that the contents of the conversation are about the first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the contents of the conversation about the first irradiation object detected by the detection unit 12 so that the state where the second light is irradiated on the second irradiation object changes to a state where the first light is irradiated on at least the first irradiation object and the second light is irradiated on the second irradiation object.

[0129] According to this, the detection unit 12 detects the content of the person's conversation, and thus it is possible to detect whether or not the person is interested in the first irradiation object. When the person shows an interest in the first irradiation object, the control unit 13 can irradiate the first irradiation object and the second irradiation object with the first light and the second light. Therefore, it is expected that the attractiveness of the first irradiation object will be highlighted by increasing the attractiveness of the first irradiation object to a person moving toward the first irradiation object.

[0130] Moreover, the lighting production system 1 of a twelfth aspect according to the present embodiment is the lighting production system 1 according to any one of the first to eleventh aspects. In this case, the lighting production system 1 includes a detection unit 12 that detects the motion of a person present in a space, and a control unit 13 that controls the first light source 11a and the second light source 11b based on the result of detection by the detection unit 12. When the detection unit 12 detects that the motion is a motion of a person on a first irradiation object, the control unit 13 controls the first light source 11a and the second light source 11b based on the motion of the person on the first irradiation object detected by the detection unit 12 so that the state where the second light is irradiated on the second irradiation object changes to a state where the first light is irradiated on at least the first irradiation object and the second light is irradiated on the second irradiation object.

[0131] According to this, the detection unit 12 detects the motion of a person, and thus it is possible to detect the reaction of the person to the first irradiation object. When the person reacts to the first irradiation object (for example, when the person shows interest), the control unit 13 can irradiate the first light and the second light to the first irradiation object and the second irradiation object. Therefore, it is expected that the attractiveness of the first irradiation object will be highlighted by increasing the attractiveness of the first irradiation object to a person moving toward the first irradiation object.

[0132] In addition, a lighting presentation method of a thirteenth aspect of this embodiment includes irradiating a first light onto a first illumination object, and irradiating a second light onto a second illumination object on which the first illumination object is disposed, the second light including at least a part of a floor, a wall, and a ceiling, wherein the first light is different from the second light, and the second light illuminates a second illumination object present around the first illumination object, and is at least one of light having a different color from the first light and light that changes dynamically.

[0133] This method also provides the same effects as those described above.

[0134] A program according to a fourteenth aspect of the present embodiment is a program that enables a computer to execute the lighting presentation method according to the thirteenth aspect.
