Embodiments for Carrying Out the Invention

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] <System Configuration> First, the overall system configuration will be described. FIG. 1 is a block diagram showing each configuration of an illuminated object appreciation system 100 according to an embodiment of the present invention. FIG. 2 is a schematic diagram showing the illuminated object appreciation system 100 according to the present embodiment.

[0011] As shown in FIGS. 1 and 2, the illuminated object (such as a painting) appreciation system 100 of the present embodiment includes a controller master unit 1, a plurality of illumination devices 2a to 2e, an audio device 4, illuminated objects 5a to 5e, a remote control device 6, and a plurality of controller slave units 7a to 7e.

[0012] The controller master unit 1 is an information processing device that controls the entire illuminated object appreciation system 100. The controller master unit 1 performs illumination control of the illumination devices 2a to 2e via the controller slave units 7a to 7e. The controller master unit 1 can transmit a control signal including a timing signal to each of the controller slave units 7a to 7e.

[0013] The controller master unit 1 and the controller slave units 7a to 7e are connected by wire such as a LAN cable or wirelessly such as Wifi (registered trademark). Further, the controller master unit 1 also functions as a music player that controls the audio device 4. The controller master unit 1 and the audio device 4 are connected by wire such as an RCA cable or wirelessly.

[0014] The lighting devices 2a to 2e are arranged corresponding to each of the plurality of illuminated objects 5a to 5e. The lighting devices 2a to 2e irradiate the illuminated objects 5a to 5e based on the control information from the controller master unit 1 received via the controller slave units 7a to 7e. A configuration example of the lighting devices 2a to 2e will be described later.

[0015] The audio device 4 is an audio output device that outputs voices such as music transmitted from the controller master unit 1. The audio device 4 includes an amplifier 41 that receives and amplifies an audio signal from the controller master unit 1, and a speaker 42 that emits the signal amplified by the amplifier 41. In the present embodiment, music corresponding to painting appreciation is reproduced by the audio device 4.

[0016] The illuminated objects 5a to 5e are paintings or the like containing an ultraviolet-excited luminescent substance that emits visible light based on irradiation with ultraviolet light. Paintings or the like refer to those in which a landscape, an object, characters, an image, etc. are expressed as a two-dimensional image (e.g., paintings or the like, books, calligraphy and paintings, prints). The illuminated objects 5a to 5e become the illumination targets of the lighting device 2. The illuminated objects 5a to 5e in the present embodiment are paintings with different contents. A configuration example of the paintings will be described later.

[0017] The remote operation device 6 is a remote controller for operating the controller master unit 1. The remote operation device 6 in the present embodiment can control the controller master unit 1 by infrared communication. The user can operate various functions of the illuminated object appreciation system 100 such as lighting control and music control by the remote operation device 6. A configuration example of the remote operation device 6 will be described later.

[0018] The controller slave units 7a to 7e are provided corresponding to each of the illuminated objects 5a to 5e. That is, the controller slave units 7a to 7e are arranged corresponding to each of the plurality of lighting devices 2a to 2e.

[0019] Also, the controller slave units 7a to 7e can control the lighting for the illuminated objects 5a to 5e based on the timing signal received from the controller master unit 1. The controller slave units 7a to 7e transmit the information for controlling the lighting device 2 received from the controller master unit 1 to the lighting devices 2a to 2e.

[0020] The controller slave units 7a to 7e have two connection parts for performing master-slave connection or slave-slave connection. The connection parts are constituted by, for example, two RJ45 terminals compatible with a LAN cable. In this embodiment, the controller slave unit 7a is directly connected to the controller master unit 1 via a LAN cable, and the controller slave unit 7a is connected to the controller slave unit 7b via a LAN cable. Similarly, the controller slave unit 7b is connected to the controller slave unit 7c via a LAN cable, the controller slave unit 7c is connected to the controller slave unit 7d via a LAN cable, and the controller slave unit 7d is connected to the controller slave unit 7e via a LAN cable. Thus, the controller slave units 7a to 7e are configured in a daisy chain. For example, when the controller slave unit 7a receives control information for the controller slave unit 7e from the controller master unit 1, the control information is transmitted to the controller slave unit 7e via the controller slave units 7a to 7d.

[0021] The slave controllers 7a to 7e and the lighting devices 2a to 2e may be connected by wire such as a LAN cable, or may be connected wirelessly such as by infrared communication. In the present embodiment, the transmission of information from the slave controllers 7a to 7e to the lighting devices 2a to 2e is performed using infrared communication. Infrared transmitters 8a to 8e are respectively arranged in each of the slave controllers 7a to 7e, and control information is transmitted to the lighting devices 2a to 2e using the infrared transmitters 8a to 8e. The lighting devices 2a to 2e receive information transmitted from the infrared transmitters 8a to 8e of the slave controllers 7a to 7e via the infrared receivers 9a to 9e.

[0022] As shown in FIG. 2, the infrared receivers 9a to 9e are located at positions where they can receive infrared rays from the infrared transmitters 8a to 8e of the slave controllers 7a to 7e, and are arranged at positions covered by the lighting devices 2a to 2e. Further, the slave controllers 7a to 7e and the lighting control device 23 (FIG. 4) may be sized such that they can be hidden behind the illuminated objects 5a to 5e such as paintings, for example, they may be 10 cm in length × 10 cm in width × 1 cm in thickness.

[0023] The slave controller 7 preferably has a size that can be hidden behind the illuminated objects 5a to 5e such as paintings. Further, the slave controller 7 has a black housing and may include, for example, a power supply device to which a voltage such as AC100 to 120V is supplied from the outside.

[0024] Note that the network topology for connecting the components of the illuminated object appreciation system 100 such as the master controller 1, the slave controllers 7a to 7e, and the lighting devices 2a to 2e is not limited to the above-described configuration, and any arbitrary topology can be used. For example, the master controller 1 and the slave controllers 7a to 7e corresponding to each of the illuminated objects 5a to 5e may be bus-connected. The communication protocol between the master controller 1 and the slave controllers 7a to 7e corresponding to each of the illuminated objects 5a to 5e may be the Internet protocol.

[0025] <Hardware Configuration of Master Controller> Next, an example of the hardware that constitutes the controller master unit 1 will be described. FIG. 3 is a block diagram showing the hardware configuration of the controller master unit 1 according to the present embodiment. The controller master unit 1 is a computer including a CPU (Central Processing Unit) 11 as a processor, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20.

[0026] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 into the RAM 13. The RAM 13 also appropriately stores data and the like necessary for the CPU 11 to execute various processes. The CPU 11, ROM 12, and RAM 13 are interconnected via the bus 14. The input / output interface 15 is also connected to this bus 14.

[0027] The output unit 16, input unit 17, storage unit 18, communication unit 19, and drive 20 are connected to the input / output interface 15. The output unit 16 is configured to be connected to a display, a speaker, and the like. The output unit 16 outputs various information as images and sounds. In the present embodiment, the output unit 16 includes a set of red and white RCA terminals for audio and one RJ45 terminal compatible with a LAN cable for connecting the controller master unit 1 and the controller slave units 7a to 7e for lighting control. The input unit 17 is configured for various information to be input. The input unit 17 is configured by a configuration for receiving an instruction signal from the remote control device 6 and buttons for giving instructions for various operations. Operating means such as a keyboard and a mouse may be connected to the input unit 17.

[0028] The memory unit 18 is composed of a hard disk, DRAM (Dynamic Random Access Memory), etc., and stores various data. The communication unit 19 communicates with other devices via a network including the Internet.

[0029] In the drive 20, a removable medium 20a such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory is appropriately mounted. The program read from the removable medium 20a by the drive 20 is installed in the memory unit 18 as necessary. Also, the removable medium 20a can store various data stored in the memory unit 18 in the same manner as the memory unit 18.

[0030] In this embodiment, the removable medium 20a is an SD card, a USB memory, etc. in which sound source information for reproduction is stored, and music, environmental sounds, etc. are reproduced from the sound device 4 based on the sound source information stored in the SD card or USB memory.

[0031] Note that the controller main unit 1 may have a housing such as black with a size of about 20 cm in length and width and about 10 - 15 cm in height, and may include a power supply device to which a voltage such as AC100 - 120V is supplied from the outside.

[0032] The hardware configuration described here is merely an example, and a configuration different from that in FIG. 2 may be used. Also, the controller main unit 1 may be composed of two or more computers.

[0033] <An example of a lighting device> Next, a configuration example of the lighting device 2 will be described. FIG. 4 is a functional block diagram showing a configuration example of the lighting device 2 according to this embodiment. In the description of a plurality of configurations such as the lighting devices 2a - 2e in this specification, when explaining a common configuration that is not distinguished from other configurations, it will be described by omitting the alphabet from the reference signs such as "lighting device 2" and "illuminated object 5".

[0034] As shown in FIG. 4, the lighting device 2 includes a first lighting lamp 21, a second lighting lamp 22, and a lighting control device 23. The lighting device 2 may have a plurality of first lighting lamps 21 and a plurality of second lighting lamps 22. The plurality of first lighting lamps 21 and the plurality of second lighting lamps 22 may each illuminate different regions of the object to be illuminated 5.

[0035] The first lighting lamp 21 is a lighting lamp capable of irradiating visible light onto the object to be illuminated 5 described later. The first lighting lamp 21 includes, for example, an incandescent bulb, a halogen lamp, and an LED bulb. Visible light is light having a wavelength visible to the human eye, and in terms of the wavelength range, it refers to light having a wavelength of 380 nm or more and 780 nm or less, or light having a wavelength of 400 nm or more and 800 nm or less. The first lighting lamp 21 has a spectrum having a half-value width of, for example, 1000 nm or more based on the entire wavelength range. That is, the first lighting lamp 21 provides gentle illumination having a very wide spectrum range extending from the visible region to the infrared light region. In the present embodiment, the first lighting lamp 21 has an ultraviolet light intensity that is 1 / 10 or less, preferably 1 / 100 or less, and suitably 1 / 1000 or less of the intensity of the ultraviolet light emitted by the second lighting lamp 22 described later.

[0036] The first lighting lamp 21 illuminates the object to be illuminated 5 described later from above or below. The position of the first lighting lamp 21 may be determined according to the position of the frame of the object to be illuminated 5 described later (a positional relationship may be defined). Note that the first lighting lamp 21 may also illuminate the object to be illuminated 5 from the right side and / or the left side, in addition to above and below. Further, it may illuminate the same object to be illuminated 5 from a plurality of directions.

[0037] The first illuminating lamp 21 preferably has a color temperature of 4000K or less. Light with a color temperature of 4000K or less is known to bring about relaxation and relieve stress as compared to light with a color temperature higher than 4000K. On the other hand, daylight-colored or daylight-white light with a color temperature higher than 4000K, for example, blue-white light with a color temperature ranging from 6000K to 8000K, not only causes the body to tense up through eye irritation but also increases the contrast of the image and makes the outline prominent. And such blue-white light impairs the gentle scene of a specific drawing object by the second illuminating lamp 22 described later and the effect of gradually changing the color tone and / or brightness within the original screen. In some cases, the atmosphere of the illuminated object 5 or the like is impaired. Hereinafter, the effect of gradually changing the color tone and / or brightness within the screen is referred to as a gradation effect. The gradation effect is the effect of gradually changing the color tone and / or brightness within the screen. When providing a relaxing and gentle scene and a gradation effect, it is preferable to use light with a color temperature of 4000K or less as described above.

[0038] As described above, the half-value width of the light spectrum of the first illuminating lamp 21 is preferably a wide band of 1000 nm or more based on the entire wavelength range. As the first illuminating lamp, for example, it is preferable to use a halogen lamp. The applicant also tried LED lighting, but noticed that when using LED lighting as the first illuminating lamp, the atmosphere of paintings and the like would be impaired. When using LED lighting having a narrow band as the first illuminating lamp 21, the color rendering property may be lowered. In a drawing having a reflection spectrum in a wavelength range outside the narrow band, the intended reflected light cannot be obtained. As a result, it is difficult to realize the intended display. For example, when using LED lighting having the emission center only at blue (bandwidth 20 nm centered at 450 nm), green (for example, bandwidth 20 nm centered at a wavelength of 520 nm), and red (for example, bandwidth 20 nm centered at a wavelength of 630 nm), the intended display is difficult to realize. For example, for a yellow drawing having a reflection peak near 570 nm, the expression of the drawing by the yellow of the peak wavelength cannot be obtained, and there is a possibility that the intended display cannot be obtained.

[0039] The second illumination lamp 22 is, for example, an illumination lamp capable of irradiating ultraviolet light. Ultraviolet light refers to light with a wavelength of 300 nm or more and 400 nm or less, and has a narrower wavelength range than ordinary "ultraviolet light". The ultraviolet light can be emitted by a black light (for example, a fluorescent tube that emits ultraviolet rays in the UVA region). The second illumination lamp 22 is, for example, a fluorescent tube (so-called black light). In the present embodiment, the second illumination lamp 22 irradiates the object to be illuminated 5 described later with light having a wavelength of 300 nm or more and 400 nm or less, generally ultraviolet rays called UVA.

[0040] The second illumination lamp 22 irradiates the object to be illuminated 5 from the Y1 direction or the Y2 direction, for example. Regarding the illumination direction, the positional relationship with the frame of the object to be illuminated 5 described later may be defined. Note that the second illumination lamp 22 may illuminate the object to be illuminated 5 from the right side and / or the left side, in addition to above and below. Further, it may illuminate the same object to be illuminated 5 from a plurality of directions. Furthermore, the illumination direction of the second illumination lamp 22 may be restricted so that the illumination of the second illumination lamp 22 does not enter a human eye.

[0041] The second illumination lamp 22 irradiates the object to be illuminated 5 with ultraviolet light in a narrower wavelength range than ultraviolet light (wavelength of 10 nm or more and 400 nm or less) in the ordinary sense. A plurality of types of fluorescent materials or phosphorescent materials described later are used, and the peak wavelengths of their respective absorption spectra do not coincide. The second illumination lamp 22 is preferably ultraviolet illumination in which the half-value width of the optical spectrum including each peak wavelength is 50 nm or more. Thereby, light emission excited at the peak absorption wavelengths of the fluorescent material and the phosphorescent material can be obtained. And light emission corresponding to the densities of the fluorescent material and the phosphorescent material can be obtained. As a result, a gradation in the in-plane light emission intensity reflecting the gradation of the densities of the fluorescent material and the phosphorescent material can be obtained, and an intended gradation effect can be obtained. An expression that does not impair the atmosphere of a painting or the like becomes possible. When LED ultraviolet illumination is used as the second illumination lamp 22, it is difficult to obtain a gentle and delicate gradation effect described later. This is because there are many cases where the half-value width of LED ultraviolet illumination is 50 nm or less. In a light-emitting material with low absorption at the peak wavelength of LED ultraviolet illumination, the light emission may be impaired. Therefore, there is a possibility that the atmosphere of a painting or the like may be impaired.

[0042] The lighting control device 23 controls the illumination irradiated to the object to be illuminated 5. The lighting control device 23 supplies current to the first illumination lamp 21 and the second illumination lamp 22. Further, the lighting control device 23 controls the first illumination lamp 21 so as to irradiate the object to be illuminated 5 with visible light. Further, the lighting control device 23 controls the second illumination lamp 22 so as to irradiate the object to be illuminated 5 with ultraviolet light. An infrared receiver 9 is connected to the lighting control device 23, and control information from the controller main unit 1 is received by the infrared receiver 9 via the infrared transmitter 8 of the controller slave unit 7.

[0043] <An example of the object to be illuminated> Next, regarding the objects to be illuminated 5a to 5e, the configuration of the object to be illuminated 5c will be described as an example. FIG. 5 is a diagram showing a cross-sectional view and a display example of the object to be illuminated 5c according to the present embodiment.

[0044] As shown in FIG. 5, the illuminated object 5c has a base material 50, a first graphic layer 51, and a second graphic layer 52. As shown in FIG. 4, the illuminated object 5c receives irradiation of visible light from the first illumination lamp 21 and irradiation of ultraviolet light from the second illumination lamp 22. FIG. 5(a) is a cross-sectional view of the illuminated object 5c shown in FIG. 4 cut along line s1-s1. The base material 50 is, for example, a canvas in which a canvas is stretched over a wooden frame.

[0045] As shown in FIG. 5(a), the first graphic layer 51 is in contact with the base material 50 and is located on the Z1 direction side of the base material 50. The first graphic layer 51 visibly displays the first graphic under visible light. The first graphic includes a drawing object. The drawing object is also referred to as a drawing object and refers to each image constituting a two-dimensional image. As the drawing object, in the example of the landscape painting shown in FIG. 4, trees, Mount Fuji, and the sky are applicable.

[0046] The first graphic layer 51 has color materials in the visible region. The color materials in the visible region refer to substances that reflect light of colors visible to the human eye by illuminating visible light and are color materials in the ordinary sense. The color materials in the visible region include substances that reflect achromatic colors such as white color materials.

[0047] The achromatic color refers to a color in the L*a*b* color space defined by the International Commission on Illumination standard (CIE1976) where -10 ≤ a* ≤ 10 and -10 ≤ b* ≤ 10, preferably a color where -5 ≤ a* ≤ 5 and -5 ≤ b* ≤ 5, and suitably a color where -3 ≤ a* ≤ 3 and -3 ≤ b* ≤ 3. White refers to an achromatic color and a color where 80 ≤ L* in the L*a*b* color space, preferably an achromatic color and a color where 85 ≤ L* in the L*a*b* color space, and suitably an achromatic color and a color where 90 ≤ L* in the L*a*b* color space. However, the achromatic color materials and white color materials are not limited to this.

[0048] The first graphic layer 51 is, for example, an oil painting layer. The first graphic layer 51 may be a print. The first graphic layer 51 may be created by a printing machine. The first graphic layer 51 may be one in which an image is displayed by a combination of dots of primary colors (e.g., cyan, magenta, yellow, and black), such as in gravure printing, screen printing, intaglio printing, letterpress printing, etc.

[0049] The first graphic layer 51 may be, for example, a hand-painted oil painting layer or one mass-produced by a printing machine. The process of forming the first graphic layer 51 includes, for example, a process of applying a coloring material in the visible region over a period of at least 60 seconds or more.

[0050] As shown in FIG. 5(a), the second graphic layer 52 is located on the side opposite to the base material 50, that is, on the Z1 direction side, in contact with the first graphic layer 51. The second graphic layer 52 visibly displays the second graphic under ultraviolet light irradiation. The second graphic layer 52 has an ultraviolet-excited luminescent material that emits visible light based on ultraviolet light irradiation. The second graphic includes a drawing object. The drawing object, also referred to as a drawing object, refers to each individual figure that constitutes a two-dimensional image. In the example of the landscape painting shown in FIG. 4, the sea of clouds 521 and the moon 522 correspond to the drawing object. The second graphic layer 52 has a plurality of types of ultraviolet-excited luminescent materials, and each ultraviolet-excited luminescent material emits various colors, such as violet-blue, red-violet, red, orange, yellow-orange, yellow, yellow-green, etc., upon ultraviolet light irradiation. The second graphic is invisible under visible light and visible under ultraviolet light.

[0051] An ultraviolet-excited luminescent substance is a substance that emits visible light by illuminating ultraviolet light. For example, the ultraviolet-excited luminescent substance is a fluorescent substance or a phosphorescent substance. The ultraviolet-excited luminescent substance is transparent or white under visible light without illuminating ultraviolet light. Transparent means that the visible light transmittance after visual sensitivity correction is 90% or more. The fluorescent substance emits visible light while being irradiated with ultraviolet light, and the emission stops when the ultraviolet irradiation stops. With respect to the lighting (irradiation) and extinguishing (stopping of irradiation) of ultraviolet light, fluorescence emits and extinguishes without a time delay. The phosphorescent substance emits visible light while being irradiated with ultraviolet light, and the emission is maintained for a certain period of time even after the ultraviolet irradiation stops. The phosphorescent substance is also called a energy storage substance. With respect to the lighting or irradiation of ultraviolet light, the phosphorescent substance emits light with a time delay and extinguishes with a time delay. With respect to the extinguishing of ultraviolet light or the stopping of irradiation, the phosphorescence disappears with a time delay.

[0052] The ultraviolet-excited luminescent substance is adhered to a base material 50 (e.g., painting, book, calligraphy and painting, print) in which a landscape, an object, characters, an image, etc. are represented as a two-dimensional image by a first graphic layer 51. The second graphic layer 52 is formed, for example, by applying an ultraviolet-excited luminescent substance to the base material 50 on which the first graphic layer 51 is formed. The ultraviolet-excited luminescent substance is a pigment or a dye. A pigment is a material that has a color and is insoluble in water or other solvents. A dye is a material that has a color and is soluble in water or other solvents.

[0053] The second graphic layer 52 is formed by a second graphic. The second graphic is, for example, a sea of clouds 521 and a moon 522 in FIG. 4. Here, the second graphic has a specific graphic. The specific graphic is a graphic having a gradation area. The gradation area is an area where the hue, lightness, and / or chroma observed in the light emission from the ultraviolet-excited luminescent material gradually change in the plane under ultraviolet irradiation. For example, the specific graphic is the sea of clouds 521 in the drawing of Mount Fuji shown in FIG. 4. Hereinafter, the sea of clouds 521 will be described as an example of the specific graphic. The second graphic not similar to the specific graphic does not have a gradation area. For example, the moon 522 does not have a gradation area. Hereinafter, the moon 522 will be described as an example of the second graphic that is not a specific graphic.

[0054] An example with a gradation area where the hue, lightness, and / or chroma gradually change in the plane under ultraviolet irradiation will be described. The change in the display color will be described using the CIE1976 chromaticity diagram coordinates. The area is divided into sections of 4 millimeters by 4 millimeters, and the average value of the L*, a*, and b* values of the light emission from the ultraviolet-excited luminescent material within each section is derived by existing techniques. In the gradation area, under uniform ultraviolet irradiation, it is preferable that the difference in the average value of the L* values in adjacent 4-millimeter-by-4-millimeter sections is within 30, the difference in the average value of the a* values is within 30, and / or the difference in the average value of the b* values is within 30. Thereby, a natural and smooth drawing expression becomes possible.

[0055] Preferably, in the gradation area, the difference in the average value of the L* values in adjacent 4-millimeter-by-4-millimeter sections may be within 20, the difference in the average value of the a* values may be within 20, and / or the difference in the average value of the b* values may be within 20. Thereby, the presence of the gradation can be easily discriminated, and a delicate drawing expression becomes possible.

[0056] Preferably, in the gradation region, the difference in the average value of L* values in adjacent 4 mm square sections may be within 10, the difference in the average value of a* values may be within 10, and / or the difference in the average value of b* values may be within 10. This enables a delicate pictorial expression in which it is barely possible to determine whether or not a gradation is applied.

[0057] In the gradation region, the lightness changes by, for example, 20 or more in terms of the L* value. The lightness may preferably change by 40 or more, and suitably by 60 or more. This enables a pictorial expression with a clear distinction between day and night.

[0058] The ultraviolet excitation luminescent substance of the sea of clouds 521 (specific figure) contains a pigment. The sea of clouds 521 in the present embodiment, by containing a pigment, brings about sufficient in-plane changes in display colors with high reproducibility. The in-plane changes in the display colors are measured, for example, based on the amount of change in coordinates in the L*a*b* color space defined by the International Commission on Illumination standard (CIE1976) as described above. On the other hand, the second figure coated with a dye such as a brush is suitable for a flat and non-gradated display. The moon 522 has, for example, a dye coated with a brush.

[0059] The sea of clouds 521 may have, as a gradation region, a region where the hue, lightness, and / or chroma gradually change over time in the light emission from an ultraviolet excitation luminescent substance under ultraviolet light irradiation. Hereinafter, such a gradation is referred to as a temporal gradation, and the region exhibiting the temporal gradation is referred to as a temporal gradation region. The region where the sea of clouds 521a, the sea of clouds 521b, and the sea of clouds 521c overlap is the temporal gradation region that realizes the temporal gradation. At the position indicated by the reference symbol P in FIGS. 4 and 5(c), the sea of clouds 521a, the sea of clouds 521b, and the sea of clouds 521c overlap. The change in the expression color at this position will be described.

[0060] The sea of clouds 521a shown in Fig. 5(c) emits yellow-orange light. The sea of clouds 521a is formed by a second graphic layer 52 having a fluorescent substance that emits yellow-orange light under ultraviolet irradiation. The sea of clouds 521b shown in Fig. 5(c) emits orange light. The sea of clouds 521b is formed by a second graphic layer 52 having a phosphorescent substance that emits orange light under ultraviolet irradiation. The phosphorescent substance that emits orange light emits phosphorescence after a predetermined time, for example, 30 seconds, has elapsed since ultraviolet irradiation. The phosphorescent substance that emits orange light emits phosphorescence for a predetermined time, for example, about 30 seconds, even after ultraviolet irradiation has ceased. The sea of clouds 521c shown in Fig. 5(c) emits red light. The sea of clouds 521c is formed by a second graphic layer 52 having a phosphorescent substance that emits red light under ultraviolet irradiation. The phosphorescent substance that emits red light emits phosphorescence after a longer time has elapsed than the phosphorescent substance that emits orange light after ultraviolet irradiation. The phosphorescent substance that emits red light emits phosphorescence for a longer time than the phosphorescent substance that emits orange light even after ultraviolet irradiation has ceased. The phosphorescent substance that emits red light emits phosphorescence, for example, 1 minute after ultraviolet irradiation. The phosphorescent substance that emits red light emits phosphorescence for, for example, about 1 minute even after ultraviolet irradiation has ceased.

[0061] As described above, the configuration of the illuminated object 5c has been described as an example. For the other illuminated objects 5a, 5b, 5d, and 5e, although the designs are different, they are assumed to have the same configuration such as the base material 50, the first graphic layer 51, and the second graphic layer 52.

[0062] <System Control by the Controller Master Unit> The controller master unit 1 can individually control the illumination of each of the illuminated objects 5a to 5e, and can also control each of the illuminated objects 5a to 5e simultaneously.

[0063] First, the individual control of the illumination of the illuminated object 5 by the controller master unit 1 will be described. The controller master unit 1 can control the illumination of the illuminated object 5 as follows via the controller slave unit 7 and the lighting control device 23.

[0064] The master controller 1 can control the lighting of the illuminated object 5 to include, for example, a first state in which the lighting of the first lighting lamp 21 is maintained in a bright state, a second state in which the lighting of the first lighting lamp 21 gradually dims from the first state, a third state in which the lighting of the first lighting lamp 21 is maintained in a dark state (e.g., off state), and a fourth state in which the lighting of the first lighting lamp 21 gradually brightens from the third state.

[0065] In addition, the master controller 1 can control the lighting of the illuminated object 5 such that, for example, when the lighting of the first lighting lamp 21 is in the first state, the lighting of the second lighting lamp 22 is maintained in the off state, and when the lighting of the first lighting lamp 21 is in the third state, the second lighting lamp 22 is maintained in the on state.

[0066] Furthermore, the master controller 1 can control the lighting of the illuminated object 5 such that the second lighting lamp 22 turns on when the lighting of the first lighting lamp 21 is in the second state and turns off when the lighting of the first lighting lamp 21 is in the fourth state.

[0067] Also, the master controller 1 can control the second lighting lamp 22 to gradually turn on when the lighting of the first lighting lamp 21 is in the second state and gradually turn off when the lighting of the first lighting lamp 21 is in the fourth state.

[0068] The master controller 1 may be controlled to repeat the first state to the fourth state. That is, after the fourth state, the first state may start again. Also, the maintenance periods of the first state, the second state, the third state, and the fourth state coincide within a range of ±5 seconds, desirably within a range of ±3 seconds, and preferably may be the same.

[0069] Next, the simultaneous control of the lighting for a plurality of illuminated objects 5a to 5e by the master controller 1 will be described.

[0070] The master controller 1 can execute synchronous control to control the illumination of the first illumination lamps 21 of the illuminated objects 5a to 5e simultaneously to the first state, the second state, the third state, and the fourth state, for example. In this case, the illumination states of the illuminated objects 5a to 5e change at the same timing.

[0071] In addition, the master controller 1 can also execute time difference control for performing illumination control (individual control) with a time difference for the illuminated objects 5a to 5e. For example, the start timing of the first state of the first illumination lamps 21 of the illuminated objects 5a to 5e may be shifted and started with a predetermined time difference (e.g., 90 seconds). Also in this time difference control, the maintenance periods of the first state, the second state, the third state, and the fourth state coincide within a range of ±5 seconds, desirably within a range of ±3 seconds, and preferably may be the same.

[0072] In the time difference control, the number of the illuminated objects 5a to 5e is not particularly limited. In this embodiment, five paintings are the illuminated objects 5a to 5e. An example of the time difference control for the five illuminated objects 5a to 5e will be described. In the time difference control, the illumination states from the first state to the fourth state change with a time difference for each of the illuminated objects 5a to 5e.

[0073] FIG. 6 is a schematic diagram showing an example of the start timing of illumination control for a plurality of illuminated objects 5a to 5e in time difference control. In FIG. 6, an example is shown in which illumination control for changing the illumination state from the first state to the fourth state is performed with a time difference (90 seconds) in the order of the illuminated object 5a, the illuminated object 5b, the illuminated object 5c, the illuminated object 5d, and the illuminated object 5e. For the illuminated object 5a where the illumination control is first started, 180 seconds have already elapsed since the start of the illumination control. For the illuminated object 5b where the illumination control is started next to the illuminated object 5a, 90 seconds have elapsed since the start of the illumination control. The illuminated object 5c is immediately after the start of the illumination control. The illumination control for the illuminated object 5d is started 90 seconds after this state, and the illumination control for the illuminated object 5e is started 180 seconds after this state. In this example, the illumination control for the illuminated objects 5a to 5e is performed with a time difference of 90 seconds. Therefore, the change in the illumination state of the last illuminated object 5e starts 360 seconds after the illumination control for the first illuminated object 5a is started.

[0074] The time difference control may be performed such that the illumination control is started in the order of the illuminated object 5e, the illuminated object 5d, the illuminated object 5c, the illuminated object 5b, and the illuminated object 5a. Also, instead of the order of the illuminated objects 5a to 5e, the illumination control can be sequentially started in the order from the center to the two adjacent ones. Thus, the order of the time difference control is not particularly limited.

[0075] Note that the controller master unit 1 may perform time difference control such that when the number of paintings or the like is N, the predetermined time difference is A seconds, and the time from the start of the first state to the end of the fourth state is B seconds, the relationship N×A = B holds.

[0076] In addition to lighting control, the controller master unit 1 also performs acoustic control using the acoustic device 4. The acoustic control may be controlled to be linked to the lighting state of the lighting control, or may be independently and individually controlled without being linked to the lighting state of the lighting control. When linked to the lighting state of the lighting control, the controller master unit 1 can also perform control to reproduce a sound source corresponding to each state or combination of the first state, the second state, the third state, and the fourth state of the first lighting lamp 21 and the second lighting lamp 22. In this way, the controller master unit 1 can control the timing and volume of outputting sound.

[0077] <An example of a remote control device> Next, a configuration example of the remote control device 6 will be described. FIG. 7 is a diagram showing a configuration example of the remote control device 6 according to the present embodiment. The remote control device 6 is an information processing terminal such as a smartphone, a wearable terminal, or a tablet, for example. By executing an application software program on the remote control device 6, the operation image shown in FIG. 7 is displayed on the display unit of the remote control device 6.

[0078] As shown in FIG. 7, the remote control device 6 includes a plurality of lighting control instruction units 61, an individual lighting control instruction unit 62, and a sound source reproduction instruction unit 63. By operating each instruction unit of the remote control device 6, the user can instruct the controller master unit 1 to perform various lighting controls and acoustic controls.

[0079] The plurality of lighting control instruction units 61 are designating means for causing the controller master unit 1 to execute lighting control for a plurality of illuminated objects 5a to 5e. The plurality of lighting control instruction units 61 include a synchronization instruction unit 611 and a time difference instruction unit 612.

[0080] The synchronization instruction unit 611 is designating means for instructing the controller master unit 1 to perform the above-described synchronization control in which the lighting states of a plurality of illuminated objects 5a to 5e are simultaneously changed in a 90-second cycle. The synchronization instruction unit 611 includes buttons for designating on / off of the synchronization control, starting the synchronization control, temporarily stopping the synchronization control, and resetting (stopping) the synchronization control.

[0081] The time difference instruction unit 612 is a designation means for instructing the controller main unit 1 to perform the above-described time difference control for sequentially starting illumination control with a 90-second cycle for a plurality of illuminated objects 5a to 5e. The time difference instruction unit 612 includes a button for instructing time difference control in the order of the illuminated object 5a, the illuminated object 5b, the illuminated object 5c, the illuminated object 5d, and the illuminated object 5e, and a button for instructing time difference control in the order of the illuminated object 5e, the illuminated object 5d, the illuminated object 5c, the illuminated object 5b, and the illuminated object 5a.

[0082] The illumination individual control instruction unit 62 is a designation means for causing the controller main unit 1 to execute the above-described individual control for changing the illumination state for each of the illuminated objects 5a to 5e in a 90-second cycle. The illumination individual control instruction unit 62 includes a first individual control instruction unit 621 corresponding to the illuminated object 5a, a second individual control instruction unit 622 corresponding to the illuminated object 5b, a third individual control instruction unit 623 corresponding to the illuminated object 5c, a fourth individual control instruction unit 624 corresponding to the illuminated object 5d, and a fifth individual control instruction unit 625 corresponding to the illuminated object 5e. Each of the first individual control instruction unit 621, the second individual control instruction unit 622, the third individual control instruction unit 623, the fourth individual control instruction unit 624, and the fifth individual control instruction unit 625 includes a button for instructing on / off of control, start of synchronous control, temporary stop of synchronous control, and reset (stop) of synchronous control. By operating each instruction unit of the illumination individual control instruction unit 62, independent illumination control (individual control) for each of the illuminated objects 5a to 5e is executed.

[0083] As described above, the remote control device 6 can specify three types of illumination control patterns for the controller main unit 1.

[0084] The sound source playback instruction unit 63 is a specifying means for causing the controller master unit 1 to execute acoustic control. The sound source playback instruction unit 63 includes buttons for instructing playback, pause, and stop of the sound source. When the controller master unit 1 receives an instruction regarding sound source playback from the sound source playback instruction unit 63, the controller master unit 1 acquires sound source information from a removable medium 20a such as an SD card inserted into the drive 20, and performs control to output an output signal based on the sound source information from the speaker 42 through the amplifier 41 of the acoustic device 4.

[0085] In the present embodiment, since the lighting control and the acoustic control operate independently, it is possible to switch the operation of the lighting (lighting control) from a plurality of controls (synchronous control or time difference control) to individual control while a sound source such as music is being played.

[0086] The above describes one embodiment of the present invention. Next, a modification having a configuration different from the above embodiment will be described. In the following description, components that are common or similar to the above embodiment may be denoted by the same reference numerals, and detailed description thereof may be omitted.

[0087] Next, a modification of the first lighting lamp 21 and the second lighting lamp 22 will be described. The illumination of the adjacent illuminated objects 5a to 5e by the first lighting lamp 21 may be in opposite directions to each other. That is, the first lighting lamp 21 corresponding to the first illuminated object 5a may be disposed below the first illuminated object 5a, and the first lighting lamp 21 corresponding to the second illuminated object 5b may be disposed above the second illuminated object 5b. By doing so, it is possible to reduce the situation where the illumination of the first lighting lamp 21 of the first illuminated object 5a illuminates the second illuminated object 5b, or the illumination of the first lighting lamp 21 of the second illuminated object 5b illuminates the first illuminated object 5a.

[0088] Also, the illumination by the second illumination lamp 22 of the adjacent illuminated objects 5a to 5e may be in opposite directions to each other. That is, the second illumination lamp 22 of the first illuminated object 5a may be disposed below the first illuminated object 5a, and the second illumination lamp 22 of the second illuminated object 5b may be disposed above the second illuminated object 5b. By doing so, it is possible to reduce the situation where the illumination of the second illumination lamp 22 of the first illuminated object 5a illuminates the second illuminated object 5b, or the illumination of the second illumination lamp 22 of the second illuminated object 5b illuminates the first illuminated object 5a. In particular, regarding the second illumination lamp 22, it is necessary to consider preventing its illumination from illuminating the adjacent illuminated objects 5a to 5e.

[0089] Also, the number of the illuminated objects 5a to 5e is not limited to five. For example, the illuminated object 5e can be omitted to make four paintings of the illuminated objects 5a to 5d. In this case, when the illuminated objects 5a to 5d are arranged in four from left to right, the first illumination lamp 21 and / or the second illumination lamp 22 of the rightmost illuminated object 5d illuminates the illuminated object 5d such as a painting from the left side, and the first illumination lamp 21 and / or the second illumination lamp 22 of the leftmost illuminated object 5a illuminates the illuminated object 5a from the right side. The illumination by the first illumination lamp 21 and / or the second illumination lamp 22 of the second illuminated object 5c from the right and the third illuminated object 5b may be in opposite directions to each other. Further, the first illumination lamp 21 and / or the second illumination lamp 22 may be configured to illuminate all of the illuminated objects 5a to 5d or the illuminated objects 5c and 5b located at the center from above or below.

[0090] Also, when there are four illuminated objects 5a to 5d, in time difference control, when a predetermined time difference is A seconds and the time from the start of the first state to the end of the fourth state is B seconds, the relationship 4×A = B may be established. By doing so, when the first painting or the like (illuminated object 5a) is in the first state, the second painting or the like (illuminated object 5b) is in a state including the second state, the third painting or the like (illuminated object 5c) is in a state including the third state, and the fourth painting or the like (illuminated object 5d) is in a state including the fourth state. When the first painting or the like is in the second state, the second painting or the like is in a state including the third state, the third painting or the like is in a state including the fourth state, and the fourth painting or the like is in a state including the first state. When the first painting or the like is in the third state, the second painting or the like is in a state including the fourth state, the third painting or the like is in a state including the first state, and the fourth painting or the like is in a state including the second state. When the first painting or the like is in the fourth state, the second painting or the like is in a state including the first state, the third painting or the like is in a state including the second state, and the fourth painting or the like is in a state including the third state. As a result, when viewed as a whole, it becomes a very beautiful synchronization control.

[0091] Also, the heights of the adjacent illuminated objects 5a to 5e may be different from each other. The heights of the adjacent illuminated objects 5a to 5e may be such that the height of the painting or the like illuminated from below among the illuminated objects 5a to 5e is higher than the height of the painting or the like illuminated from above among the illuminated objects 5a to 5e. By doing so, it is possible to further reduce the illumination of adjacent paintings or the like.

[0092] Also, the arrangement of the illuminated objects 5a to 5e may be such that the positional relationship between the illuminated objects 5a to 5e has a figurative expression. The positional relationship between the illuminated objects 5a to 5e having a figurative expression means that what is depicted on each of the illuminated objects 5a to 5e and the arrangement of each of the illuminated objects 5a to 5e give a predetermined image to the viewer. As an arrangement of the illuminated objects 5a to 5e in which the positional relationship between the illuminated objects 5a to 5e has a figurative expression, paintings of australopithecines, homo erectus, homo neanderthalensis, homo sapiens, paintings of modern humans, etc. may be arranged in order from the left side to the right side in front of the viewer.

[0093] Further, the arrangement of the illuminated objects 5a to 5e may be considered in view of the positional relationship between the viewer and the illuminated objects 5a to 5e. Considering the positional relationship between the viewer and the illuminated objects 5a to 5e means that the arrangement of what is depicted in each painting or the like and each viewer and the illuminated objects 5a to 5e virtually creates the environment surrounding the viewer.

[0094] Next, with reference to FIG. 8, an example in which the arrangement of the illuminated objects 105a to 105h virtually creates the environment surrounding the viewer will be described. FIG. 8 is a plan view schematically showing the illuminated object viewing system 100a of a modified example. Note that in FIG. 8, illustration of some configurations such as the controller main unit 1, the amplifier 41, and the remote operation device 6 is omitted.

[0095] As shown in FIG. 8, the illuminated objects 105a to 105h may be arranged on the wall 110 or the like in the viewing room so as to surround the viewer S. Also, the lighting devices 2a to 2h corresponding to each of the illuminated objects 105a to 105h may be arranged so as to surround the viewer S.

[0096] In front of the viewer S, for example, an illuminated object 105a depicting a coastal landscape may be arranged. In front of the right side of the viewer S, an illuminated object 105b depicting seabirds and a bridge may be arranged. On the right side of the viewer S, an illuminated object 105c depicting a station building may be arranged. Behind the right side of the viewer S, an illuminated object 105d depicting a rural landscape may be arranged. Behind the viewer S, an illuminated object 105e depicting a mountain may be arranged. Behind the left side of the viewer S, an illuminated object 105f depicting a waterfall may be arranged. On the left side of the viewer S, an illuminated object 105g depicting a cliff may be arranged. In front of the left side of the viewer S, an illuminated object 105h depicting a steamship may be arranged.

[0097] Also, in this modified example, the speakers 42a to 42h are also arranged so as to surround the viewer S. The controller master unit 1 performs acoustic control corresponding to the position for each of the speakers 42a to 42h. For example, the sound of waves may be heard from the speaker 42a in front of the viewer. The sound of seabirds may be heard from the speaker 42b in front of the viewer's right. The sound of a train may be heard from the speaker 42c beside the viewer's right. The sound of a bird may be heard from the speaker 42d behind the viewer's right. The sound of trees being blown by the wind may be heard from the speaker 42e behind the viewer. The sound of a waterfall may be heard from the speaker 42f behind the viewer's left. The sound of waves hitting the cliff may be heard from the speaker 42g beside the viewer's left. The sound of a steam whistle may be heard from the speaker 42h in front of the viewer's left.

[0098] Note that the arrangement of the illuminated objects considering the positional relationship between the viewer and the illuminated objects is not limited to the above-described embodiments and modified examples. For example, as an arrangement of the illuminated objects considering the positional relationship between the viewer and the illuminated objects, illuminated objects such as paintings depicting the scenery of an island in a river in front of the viewer, the scenery of Mount Fuji on the right side of the viewer, the scenery of a coast on the left side of the viewer, and the scenery of a lush green mountain behind the viewer may be arranged respectively.

[0099] The controller master unit 1 performs time difference control on the illumination of the illuminated objects 105a to 105h such as each painting. Also, the controller master unit 1 may perform synchronous control for controlling the illumination of the illuminated objects 105a to 105h such as each painting simultaneously. That is, the illumination surrounding the viewer may change to the first state, the second state, the third state, and the fourth state simultaneously.

[0100] Also, the controller master unit 1 may perform illumination control in association with the background where the illuminated objects are arranged and the positions of the illuminated objects.

[0101] Next, referring to FIG. 9, an example of performing lighting control by associating a mural painting 210 as the background for arranging the illuminated objects 205a to 205d and the positions of the illuminated objects 205a to 205d will be described. FIG. 9 is a diagram showing a first arrangement example of the illuminated objects 205a to 205d and the lighting devices 2a to 2d according to a modified example.

[0102] As shown in FIG. 9, the illuminated objects 205a to 205d are set against the background of a mural painting 210 of a world map. Note that the meridians and parallels on the world map may or may not be shown. Four illuminated objects 205a to 205d such as paintings are arranged on this mural painting 210. In this example, the first illuminated object 205a is arranged in the range of 90° to 180° east longitude, the second illuminated object 205b is arranged in the range of 0° to 90° east longitude, the third illuminated object 205c is arranged in the range of 0° to 90° west longitude, and the fourth illuminated object 205d is arranged in the range of 90° to 180° west longitude.

[0103] The illuminated objects 205a to 205d are, for example, landscape paintings. The landscape may be the landscape of the area where the illuminated objects 205a to 205d such as the paintings are arranged.

[0104] Also, the lighting device 2a is arranged at a position corresponding to the illuminated object 205a, the lighting device 2b is arranged at a position corresponding to the illuminated object 205b, the lighting device 2c is arranged at a position corresponding to the illuminated object 205c, and the lighting device 2d is arranged at a position corresponding to the illuminated object 205d. In this example, the lighting devices 2a to 2d are all arranged above the respective illuminated objects 205a to 205d. Note that the arrangement locations of the lighting devices 2a to 2d are not particularly limited.

[0105] The controller main unit 1 of this modified example executes positive lighting control so that the relationship of 4×A = B holds, where the predetermined time difference is A seconds and the time from the start of the first state to the end of the fourth state is B seconds. By doing so, it becomes possible to appreciate the scenes of morning, noon, evening, and night in the world.

[0106] Another arrangement example using a world map will be described. FIG. 10 is a diagram showing a second arrangement example of the illuminated objects 205a to 205d and the lighting devices 2a to 2d of the modified example.

[0107] Also in the example of FIG. 10, the illuminated objects 205a to 205d such as four paintings and the lighting devices 2a to 2d are arranged against the backdrop of a mural 210 of a world map. In this example, the first illuminated object 205a is arranged in the range of 90° to 180° east longitude and 0° to 90° south latitude, the second illuminated object 205b is arranged in the range of 0° to 90° east longitude and 0° to 90° north latitude, the third illuminated object 205c is arranged in the range of 0° to 90° west longitude and 0° to 90° south latitude, and the fourth illuminated object 205d is arranged in the range of 90° to 180° west longitude and 0° to 90° north latitude. Further, in this modified example, the illuminated objects 205a to 205d are, for example, landscape paintings corresponding to the regions where they are arranged. The first illuminated object 205a is illuminated from above by the lighting device 2a, and the third illuminated object 205c is also illuminated from above by the lighting device 2c. On the other hand, the second illuminated object 205b is illuminated from below by the lighting device 2b, and the fourth illuminated object 205d is also illuminated from below by the lighting device 2d. At this time, the lighting may be controlled so that the relationship of 4×A = B holds, where A is a predetermined time difference and B is the time from the start of the first state to the end of the fourth state. By doing so, it becomes possible to appreciate the scenes of morning, noon, evening, and night around the world.

[0108] Note that the mural 210 of the world map does not necessarily have to be arranged as a background. Even without the mural of the world map, the viewer can imagine the world map.

[0109] Also, in the above-described embodiment and modified example, the environment surrounding the viewer may be created by the illumination of the first illuminating lamp 21 so as to change with morning, noon, evening, and night.

[0110] Also, in the above-described embodiment and modified example, the first illuminating lamp 21 may be indoor lighting. In addition to the indoor lighting, the first illuminating lamp 21 for individually illuminating the illuminated objects 5a to 5e such as each painting and the illuminated objects 105a to 105h may be provided.

[0111] In addition, in the above embodiment, the controller slave units 7a to 7e and the lighting devices 2a to 2e are separate bodies, but they may be integrally configured.

[0112] As described above, the illuminated object appreciation system 100 of the present embodiment includes a controller master unit 1, a first illuminating lamp 21, a second illuminating lamp 22, an illumination control device 23, and a plurality of illuminated objects 5a to 5e such as paintings (105a to 105h, 205a to 205d) that are illumination targets. The illuminated object appreciation system 100 (100a) is such that the controller master unit 1 can control at least the illumination control device 23. The illumination control device 23 can control the illumination of the illuminated objects 5a to 5e by the first illuminating lamp 21, and can also control the illumination of the illuminated objects 5a to 5e by the second illuminating lamp 22. The illumination of the illuminated objects 5a to 5e by the first illuminating lamp 21 is controlled to include a first state in which the illumination of the first illuminating lamp 21 is maintained in a bright state, a second state in which the illumination of the first illuminating lamp 21 is gradually darkened from the first state, a third state in which the illumination of the first illuminating lamp 21 is maintained in a dark state, and a fourth state in which the illumination of the first illuminating lamp 21 is gradually brightened from the third state. The second illuminating lamp 22 is controlled to turn on when the illumination of the first illuminating lamp 21 is in the second state and turn off when the illumination of the first illuminating lamp 21 is in the fourth state. The controller master unit 1 can individually control the illumination of each illuminated object 5a to 5e. The individual control of the illumination of each illuminated object 5a to 5e is control to shift the start timing of the first state of the first illuminating lamp 21 of each illuminated object 5a to 5e.

[0113] As a result, since the start timing of the illumination control of each of the plurality of illuminated objects 5a to 5e is shifted, even in a large space, it is possible to provide the viewer with a more immersive appreciation experience of the illuminated objects 5a to 5e. By controlling the illumination of a plurality of illuminated objects 5a to 5e such as paintings with one controller master unit 1 and devising the arrangement of the paintings and the illumination, it is possible to provide an illuminated object appreciation system 100 that is particularly suitable in a relatively large space. By synchronously appreciating the lighting devices 2a to 2h of a plurality of paintings and the like, it is possible to control the atmosphere of the entire relatively large space, such as in an art museum or a restaurant.

[0114] Also, in the present embodiment, the individual control of the illumination of each of the illuminated objects 5a to 5e is control for starting the start timing of the first state of the first illumination lamp 21 of each of the illuminated objects 5a to 5e with a predetermined time difference (90 seconds).

[0115] As a result, the illumination states of the respective illuminated objects 5a to 5e change regularly with a predetermined time difference, so that the sense of strangeness with respect to the change can be reduced and the immersion feeling of the viewer can be further improved.

[0116] Also, in the present embodiment, it further includes controller slave units 7a to 7e that transmit control information from the controller master unit 1 to the lighting control device 23.

[0117] Thereby, the controller master unit 1 can control the lighting control device 23 through the controller slave units 7a to 7e. By increasing or decreasing the number of the controller slave units 7a to 7e, it is possible to cope with various layouts of the illuminated objects 5a to 5e.

[0118] Also, in the present embodiment, a plurality of lighting control devices 23 are arranged corresponding to each of the illuminated objects 5a to 5e, a plurality of controller slave units 7a to 7e are arranged corresponding to each of the lighting control devices 23, and a first controller slave unit 7a, which is one of the plurality of controller slave units 7a to 7e, is connected to the controller master unit 1. The first controller slave unit 7a is connected to a second controller slave unit 7b, the second controller slave unit 7b is connected to a third controller slave unit 7c, the control information from the controller master unit 1 to the second controller slave unit 7b is transmitted via the first controller slave unit 7a, and the control information from the controller master unit 1 to the third controller slave unit 7c is transmitted via the first controller slave unit 7a and the second controller slave unit 7b.

[0119] Thereby, it is possible to realize the lighting control of the lighting control device 23 via a plurality of controller slave units 7a to 7e by the controller master unit 1 without complicating the control system.

[0120] Also, in the present embodiment, the controller master unit 1 can select, instead of the control (time difference control) that shifts the start timing, the synchronization control that synchronizes the start timing of the first state of the first illumination lamps 21 of the illuminated objects 5a to 5e.

[0121] By doing so, by selecting the synchronization control according to the types of the illuminated objects 5a to 5e, it is possible to provide the viewer with a viewing experience more suitable for the illuminated objects 5a to 5e.

[0122] Also, in the present embodiment, the illuminated object viewing system 100 further includes an acoustic device 4 that outputs sound, and the controller master unit 1 controls the acoustic device 4 to output sound.

[0123] By doing so, in addition to the lighting control, the sound by the acoustic device 4 can be added, and a viewing experience that can appeal to the viewer's senses can be provided.

[0124] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the range that can achieve the object of the present invention are included in the present invention.

[0125] Also, the above-described series of processes can be executed by hardware or by software. In other words, the above-described functional configurations are merely examples and are not particularly limited. That is, it is sufficient that the controller master unit is provided with a function capable of executing the above-described series of processes as a whole, and the functional blocks used to realize this function are not particularly limited to the above examples. Also, the location of the functional blocks is not particularly limited and may be arbitrary. For example, the functional blocks shown in FIG. 1 may be transferred to other devices or the like. Conversely, the functional blocks of other devices may be transferred to a server or the like. Also, one functional block may be configured by hardware alone, by software alone, or by a combination thereof.

[0126] When a series of processes are to be executed by software, the programs that make up the software are installed in a computer or the like from a network or a recording medium. The computer may be a computer incorporated in dedicated hardware. Also, the computer may be a computer capable of executing various functions by installing various programs, for example, a general-purpose smartphone or personal computer in addition to a server.

[0127] A recording medium containing such a program is not only constituted by a removable medium (not shown) distributed separately from the apparatus main body for providing the program, but also constituted by a recording medium or the like provided in a state pre-installed in the apparatus main body. Since the program can be distributed via a network, the recording medium may be mounted on or accessible to a computer connected to or connectable to the network.

[0128] In this specification, the step of describing a program recorded on a recording medium includes not only processes performed in time series according to the order, but also processes that may not necessarily be processed in time series, but are executed in parallel or individually. Also, in this specification, the term "system" shall mean an overall apparatus composed of a plurality of devices, a plurality of means, and the like.

[0129] Also, from the technical matters described in this specification, the technical idea of an illuminated object appreciation system including the following configuration is grasped. [Supplementary Note] The master controller can control at least the lighting control device. The lighting control device can control the lighting of a painting or the like by the first lighting lamp and can also control the lighting of a painting or the like by the second lighting lamp. The illumination of a painting or the like by the first lighting lamp is controlled to include a first state in which the illumination of the first lighting lamp is maintained in a bright state, a second state in which the illumination of the first lighting lamp is gradually darkened from the first state, a third state in which the illumination of the first lighting lamp is maintained in a dark state, and a fourth state in which the illumination of the first lighting lamp is gradually brightened from the third state. The second lighting lamp is controlled to turn on when the illumination of the first lighting lamp is in the second state and turn off when the illumination of the first lighting lamp is in the fourth state. The master controller can individually control the illumination of each painting or the like. The individual control of the illumination of each painting or the like is a control that starts the start timing of the first state of the first lighting lamp of each painting or the like with a predetermined time difference. The arrangement of the paintings or the like takes into account the positional relationship between the viewer and the paintings or the like and / or the positional relationship between the paintings or the like has a figurative expression.
