Description

Illuminated object viewing system

[0001] The present invention relates to an illuminated object viewing system.

[0002] A technique for expressing multiple scenes by irradiating a painting with a special paint that emits or reflects ultraviolet light with ultraviolet light has been known. Patent Document 1, for example, describes this type of technique. Patent Document 1 describes a technique for expressing daytime and nighttime scenes in the same painting by controlling the lighting of the painting with a special paint that emits or reflects ultraviolet light. Patent Document 1 also meets the desire of viewers who want to enjoy the painting in a more realistic way by having music play along with the changing scenes in the painting.

[0003] Patent No. 5667279

[0004] Conventional lighting devices have made it possible to enjoy the viewing of paintings and other artworks together with music in a highly realistic manner. However, conventional lighting devices were only designed to allow the viewing of a single painting. There was room for improvement in terms of enhancing the sense of realism in a space where multiple paintings and other artworks are arranged.

[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 component of an illuminated object appreciation system 100 according to one embodiment of the present invention. Fig. 2 is a schematic diagram showing the illuminated object appreciation system 100 according to this embodiment.

[0011] As shown in Figures 1 and 2, the illuminated object (painting, etc.) viewing system 100 of this embodiment includes a controller master unit 1, multiple lighting devices 2a to 2e, an audio device 4, illuminated objects 5a to 5e, a remote control device 6, and multiple 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 controls the lighting of the lighting devices 2a to 2e via the controller slave units 7a to 7e. The controller master unit 1 can transmit control signals including timing signals 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 a wired connection such as a LAN cable or wirelessly such as Wi-Fi (registered trademark). The controller master unit 1 also functions as a music player that controls the sound device 4. The controller master unit 1 and the sound device 4 are connected by a wired connection such as an RCA cable or wirelessly.

[0014] The lighting devices 2a to 2e are arranged corresponding to the plurality of illuminated objects 5a to 5e, respectively. The lighting devices 2a to 2e illuminate the illuminated objects 5a to 5e based on control information received from the master controller 1 via the slave controllers 7a to 7e. An example of the configuration of the lighting devices 2a to 2e will be described later.

[0015] The sound device 4 is an audio output device that outputs sounds such as music transmitted from the controller master unit 1. The sound device 4 includes an amplifier 41 that receives and amplifies an audio signal from the controller master unit 1, and a speaker 42 that outputs the signal amplified by the amplifier 41. In this embodiment, the sound device 4 plays music that corresponds to the viewing of a painting.

[0016] The illuminated objects 5a to 5e are paintings or the like containing an ultraviolet-excited luminescent material that emits visible light when irradiated with ultraviolet light. A painting or the like refers to a landscape, object, character, image, or the like expressed as a two-dimensional image (e.g., painting, calligraphy, calligraphy, print). The illuminated objects 5a to 5e are the illumination targets of the lighting device 2. In this embodiment, the illuminated objects 5a to 5e are paintings with different content. Configuration examples of paintings will be described later.

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

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

[0019] Furthermore, the controller slave units 7a to 7e can control the lighting of 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 each have two connection sections for connecting the master unit to the slave unit or connecting the slave units to each other. The connection sections are configured, for example, by two RJ45 terminals compatible with LAN cables. 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. In this manner, the controller slave units 7a to 7e are configured in a daisy chain configuration. 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 controller slave units 7a to 7e and the lighting devices 2a to 2e may be connected by a wire such as a LAN cable, or may be connected wirelessly such as by infrared communication. In this embodiment, information is transmitted from the controller slave units 7a to 7e to the lighting devices 2a to 2e using infrared communication. Each of the controller slave units 7a to 7e is provided with an infrared transmitter 8a to 8e, 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 the information transmitted from the infrared transmitters 8a to 8e of the controller slave units 7a to 7e via infrared receivers 9a to 9e.

[0022] 2, the infrared receivers 9a to 9e are positioned so as to receive infrared rays from the infrared transmitters 8a to 8e of the controller slave units 7a to 7e and to be covered by the lighting devices 2a to 2e. The controller slave units 7a to 7e and the lighting control device 23 (FIG. 4) may be small enough to be hidden behind the illuminated objects 5a to 5e, such as paintings, and may be, for example, 10 cm long, 10 cm wide, and 1 cm thick.

[0023] The controller slave unit 7 is preferably sized to be able to be hidden behind the illuminated objects 5a to 5e, such as paintings, etc. The controller slave unit 7 has a black housing and may include a power supply unit that receives an external voltage of, for example, 100 to 120 V AC.

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

[0025] <Hardware Configuration of Controller Master Unit> Next, an example of 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 this embodiment. The controller master unit 1 is a computer that includes 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 in accordance with programs recorded in the ROM 12 or programs loaded from the storage unit 18 into the RAM 13. The RAM 13 also stores data and the like required for the CPU 11 to execute various processes. The CPU 11, ROM 12, and RAM 13 are interconnected via a bus 14. An input / output interface 15 is also connected to this bus 14.

[0027] The input / output interface 15 is connected to an output unit 16, an input unit 17, a storage unit 18, a communication unit 19, and a drive 20. The output unit 16 is configured to be connected to a display, a speaker, etc. The output unit 16 outputs various information as images and sounds. In this embodiment, the output unit 16 includes a pair of red and white RCA terminals for audio, and an 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 to input various information. The input unit 17 is configured to receive instruction signals from the remote control device 6 and include buttons for issuing various operation instructions. An operation means such as a keyboard or a mouse may be connected to the input unit 17.

[0028] The storage unit 18 is configured with a hard disk, a 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] Removable media 20a, such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory, is appropriately loaded into the drive 20. Programs read from the removable media 20a by the drive 20 are installed in the storage unit 18 as needed. The removable media 20a can also store various data stored in the storage unit 18 in the same way as the storage unit 18.

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

[0031] The controller master unit 1 may have a black housing, for example, measuring approximately 20 cm in length and width and 10 to 15 cm in height, and may include a power supply unit that receives an external voltage of AC 100 to 120 V or the like.

[0032] The hardware configuration described here is merely an example, and may be different from the configuration shown in Fig. 2. Furthermore, controller master unit 1 may be configured by two or more computers.

[0033] <Example of Illumination Device> Next, a configuration example of the illumination device 2 will be described. Fig. 4 is a functional block diagram showing a configuration example of the illumination device 2 according to this embodiment. Note that in the description of an object having a plurality of components such as the illumination devices 2a to 2e in this specification, when describing a common configuration that is not distinguished from other configurations, the alphabet will be omitted from the reference numeral, such as "illumination device 2" or "illuminated object 5."

[0034] 4 , the lighting device 2 includes a first illuminating light 21, a second illuminating light 22, and a lighting control device 23. The lighting device 2 may include a plurality of first illuminating lights 21 and a plurality of second illuminating lights 22. The plurality of first illuminating lights 21 and the plurality of second illuminating lights 22 may each illuminate a different area of ​​the illuminated object 5.

[0035] The first illuminating lamp 21 is an illuminating lamp capable of irradiating the illuminated object 5 (described later) with visible light. The first illuminating lamp 21 may be, for example, an incandescent lamp, a halogen lamp, or an LED lamp. Visible light is light with a wavelength visible to the human eye, and in terms of wavelength range, refers to light with a wavelength of 380 nm to 780 nm or light with a wavelength of 400 nm to 800 nm. The first illuminating lamp 21 has a spectrum with a half-width of, for example, 1000 nm or more, based on the entire wavelength range. In other words, the first illuminating lamp 21 provides gentle illumination with an extremely wide spectral range extending from the visible region to the infrared region. In this embodiment, the first illuminating lamp 21 has an ultraviolet intensity of 1 / 10 or less, preferably 1 / 100 or less, and more preferably 1 / 1000 or less, of the ultraviolet intensity emitted by the second illuminating lamp 22 (described later).

[0036] The first illuminating lamp 21 illuminates the illuminated object 5 (described later) from above or below. The position of the first illuminating lamp 21 may be determined depending on the position of a frame of the illuminated object 5 (described later) (the positional relationship may be specified). The first illuminating lamp 21 may illuminate the illuminated object 5 from the right and / or left side in addition to above and below. Furthermore, the first illuminating lamp 21 may illuminate the same illuminated object 5 from multiple directions.

[0037] The first illuminating lamp 21 preferably has a color temperature of 4000 K or less. Light with a color temperature of 4000 K or less is known to induce relaxation and comfort compared to light with a color temperature higher than 4000 K. In contrast, daylight or daylight white light with a color temperature higher than 4000 K, for example, pale blue light with a color temperature of 6000 K to 8000 K, stimulates the eyes, causing physical tension, and increases the contrast of the image, highlighting contours. Furthermore, this pale blue light detracts from the serene scene of a specific object to be depicted by the second illuminating lamp 22 (described below) and the underlying effect of gradually changing color and / or brightness within the screen. In some cases, the ambiance of the illuminated object 5, etc., may be impaired. Hereinafter, the effect of gradually changing color and / or brightness within the screen is referred to as the "gradation effect." The gradation effect is the effect of gradually changing color and / or brightness within the screen. To provide a relaxing, serene scene and a gradation effect, it is preferable to use light with a color temperature of 4000 K or less, as described above.

[0038] As described above, the half-width of the optical spectrum of the first illuminating lamp 21 is preferably a broadband of 1000 nm or more, based on the entire wavelength range. It is preferable to use, for example, a halogen lamp as the first illuminating lamp. The applicant also tried LED lighting, but found that using LED lighting as the first illuminating lamp ruined the atmosphere of a painting or the like. Using LED lighting with a narrow bandwidth as the first illuminating lamp 21 may result in poor color rendering. For illustrations with a reflection spectrum outside the narrow bandwidth, the intended reflected light cannot be obtained. As a result, the intended display is difficult to achieve. For example, using LED lighting with emission centers only in blue (20 nm bandwidth centered around 450 nm), green (e.g., 20 nm bandwidth centered around 520 nm), and red (e.g., 20 nm bandwidth centered around 630 nm) makes it difficult to achieve the intended display. For example, with a yellow illustration with a reflection peak around 570 nm, the illustration may not be expressed in the yellow peak wavelength, and the intended display may not be achieved.

[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." Ultraviolet light can be emitted by a black light (e.g., a fluorescent tube that emits ultraviolet light in the UVA region). The second illumination lamp 22 is, for example, a fluorescent tube (a so-called black light). In this embodiment, the second illumination lamp 22 irradiates the illuminated object 5, which will be described later, with light with a wavelength of 300 nm or more and 400 nm or less, ultraviolet light generally referred to as UVA.

[0040] The second illuminating lamp 22 illuminates the illuminated object 5, for example, from the Y1 direction or the Y2 direction. The illumination direction may be determined based on a positional relationship with a frame of the illuminated object 5, which will be described later. The second illuminating lamp 22 may illuminate the illuminated object 5 from the right and / or left side in addition to above and below. The second illuminating lamp 22 may also illuminate the same illuminated object 5 from multiple directions. Furthermore, the illumination direction of the second illuminating lamp 22 may be limited so that the light from the second illuminating lamp 22 does not reach human eyes.

[0041] The second illuminating lamp 22 irradiates the illuminated object 5 with ultraviolet light having a narrower wavelength range than conventional ultraviolet light (wavelengths of 10 nm to 400 nm). Multiple types of fluorescent or phosphorescent materials, described below, are used, and the peak wavelengths of their absorption spectra do not coincide. The second illuminating lamp 22 preferably uses ultraviolet light whose half-width of the optical spectrum encompassing each peak wavelength is 50 nm or greater. This allows for light emission excited by the peak absorption wavelengths of the fluorescent and phosphorescent materials. This allows for light emission corresponding to the density of the fluorescent and phosphorescent materials. As a result, an in-plane gradation of light emission intensity reflecting the density gradation of the fluorescent and phosphorescent materials is achieved, achieving the intended gradation effect. This allows for expression without compromising the atmosphere of a painting, etc. Note that using LED ultraviolet lighting as the second illuminating lamp 22 makes it difficult to achieve the gentle and delicate gradation effect described below. This is because the half-width of LED ultraviolet lighting is often 50 nm or less. This may impair the light emission of light-emitting materials that have low absorption at the peak wavelengths of LED ultraviolet lighting. Therefore, there is a risk that the atmosphere of the painting or the like may be spoiled.

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

[0043] <Example of illuminated object> Next, the configuration of the illuminated object 5c will be described as an example of the illuminated objects 5a to 5e. Fig. 5 is a diagram showing a cross-sectional view and a display example of the illuminated object 5c according to this 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 is irradiated with visible light from a first illuminating lamp 21 and ultraviolet light from a second illuminating lamp 22. Fig. 5(a) is a cross-sectional view of the illuminated object 5c shown in Fig. 4 taken along line s1-s1. The base material 50 is, for example, a canvas made of canvas stretched over a wooden frame.

[0045] As shown in FIG. 5A, the first graphic layer 51 is in contact with the substrate 50 and is located on the Z1 direction side of the substrate 50. The first graphic layer 51 displays a first graphic so that it is visible under visible light. The first graphic includes a drawing target. A drawing target is also called a drawing object and refers to an individual shape that makes up a two-dimensional image. In the example of the landscape painting shown in FIG. 4, the drawing target includes trees, Mount Fuji, and the sky.

[0046] The first graphic layer 51 has color materials in the visible range. The color materials in the visible range refer to materials that reflect light of a color visible to the human eye when illuminated with visible light, and are color materials in the usual sense. The color materials in the visible range also include materials that reflect achromatic colors, such as white color materials.

[0047] An achromatic color refers to a color where -10≦a*≦10 and -10≦b*≦10 in the L*a*b* color space defined by the International Commission on Illumination (CIE 1976), preferably a color where -5≦a*≦5 and -5≦b*≦5, and more preferably a color where -3≦a*≦3 and -3≦b*≦3. White refers to a color that is achromatic and has L* of 80≦L* in the L*a*b* color space, preferably a color that is achromatic and has L* of 85≦L* in the L*a*b* color space, and more preferably a color that is achromatic and has L* of 90≦L* in the L*a*b* color space. However, achromatic and white colorants are not limited to these.

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

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

[0050] As shown in FIG. 5( a), the second graphic layer 52 is located in contact with the first graphic layer 51 on the opposite side from the substrate 50, i.e., the Z1 direction side. The second graphic layer 52 displays a second graphic that is visible when irradiated with ultraviolet light. The second graphic layer 52 contains an ultraviolet-excited luminescent material that emits visible light when irradiated with ultraviolet light. The second graphic includes a drawing target. The drawing target, also referred to as a drawing object, refers to an individual shape that constitutes a two-dimensional image. In the example of the landscape painting shown in FIG. 4, the drawing target includes a sea of ​​clouds 521 and a moon 522. The second graphic layer 52 contains multiple types of ultraviolet-excited luminescent materials, and each ultraviolet-excited luminescent material emits various colors, such as blue-purple, red-purple, red, orange, yellow-orange, yellow, and yellow-green, when irradiated with ultraviolet light. The second graphic is invisible under visible light but visible under ultraviolet light.

[0051] An ultraviolet-excited luminescent material is a material that emits visible light when irradiated with ultraviolet light. For example, an ultraviolet-excited luminescent material is a fluorescent material or a phosphorescent material. An ultraviolet-excited luminescent material is transparent or white under visible light without ultraviolet light. "Transparent" means that the visible light transmittance after luminosity correction is 90% or more. A fluorescent material emits visible light while irradiated with ultraviolet light and ceases to emit light when the ultraviolet light irradiation is stopped. Fluorescence emits and extinguishes without a time delay when ultraviolet light is turned on (irradiated) and off (irradiation is stopped). Phosphorescent materials emit visible light while irradiated with ultraviolet light and maintain their emission for a certain period of time even after the ultraviolet light irradiation is stopped. Phosphorescent materials are also called phosphorescent materials. When ultraviolet light is turned on or irradiated, phosphorescent materials emit light with a time delay and extinguish with a time delay. When ultraviolet light is turned off or irradiation is stopped, phosphorescence extinguishes with a time delay.

[0052] The ultraviolet-excited luminescent material is attached to a substrate 50 (e.g., a painting, calligraphy, or print) on which a landscape, object, character, image, or the like is expressed as a two-dimensional image by a first graphic layer 51. The second graphic layer 52 is formed, for example, by applying the ultraviolet-excited luminescent material to the substrate 50 on which the first graphic layer 51 has been formed. The ultraviolet-excited luminescent material is a pigment or a dye. A pigment is a material that has color and is insoluble in water or other solvents. A dye is a material that has color and is soluble in water or other solvents.

[0053] The second graphic layer 52 is formed by a second graphic. In FIG. 4 , the second graphic is, for example, a sea of ​​clouds 521 and a moon 522. Here, the second graphic has a specific graphic. The specific graphic is a graphic having a gradation region. A gradation region is a region in which the hue, brightness, and / or saturation observed in the light emitted from an ultraviolet-excited luminescent material under ultraviolet irradiation gradually changes within a plane. For example, the specific graphic is the sea of ​​clouds 521 in the illustration of Mount Fuji shown in FIG. 4 . Below, the sea of ​​clouds 521 will be used as an example of a specific graphic. A second graphic that is not classified as a specific graphic does not have a gradation region. For example, the moon 522 does not have a gradation region. Below, the moon 522 will be used as an example of a second graphic that is not a specific graphic.

[0054] An example will be described below involving a gradation region in which the hue, lightness, and / or saturation gradually change across a plane under ultraviolet irradiation. The change in displayed color will be explained using CIE 1976 chromaticity diagram coordinates. The region is divided into 4-millimeter square sections, and the average values ​​of the L*, a*, and b* values ​​of the light emitted from the ultraviolet-excited luminescent material within each section are calculated using existing technology. In the gradation region, under uniform ultraviolet irradiation, it is preferable that the difference in the average L* values, the difference in the average a* values, and / or the difference in the average b* values ​​between adjacent 4-millimeter square sections is within 30°. This enables natural and smooth pictorial expression.

[0055] Desirably, in the gradation region, the difference in the average value of the L* value between adjacent 4-millimeter square sections may be within 20, the difference in the average value of the a* value may be within 20, and / or the difference in the average value of the b* value may be within 20. This makes it possible to easily determine the presence of gradation and to express delicate pictures.

[0056] Preferably, in the gradation region, the difference in the average value of the L* value between adjacent 4-millimeter square sections may be within 10, the difference in the average value of the a* value may be within 10, and / or the difference in the average value of the b* value may be within 10. This enables a delicate pictorial representation in which the presence of gradation is barely discernible.

[0057] In the gradation region, the brightness changes, for example, by an L* value of 20 or more. The brightness may desirably change by 40 or more, and preferably by 60 or more. This allows for a clear depiction of the difference between day and night.

[0058] The ultraviolet-excited luminescent material of the sea of ​​clouds 521 (specific figure) contains a pigment. By including a pigment, the sea of ​​clouds 521 in this embodiment provides sufficient in-plane variation in the displayed color with high reproducibility. As described above, the in-plane variation in the displayed color is 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 (CIE 1976). Meanwhile, the second figure, to which dye is applied with a brush or the like, is suitable for a flat display without gradation. The moon 522 contains dye, for example, applied with a brush.

[0059] The sea of ​​clouds 521 may have a gradation region in which light emission from an ultraviolet-excited luminescent substance, whose hue, brightness, and / or saturation gradually change over time under irradiation with ultraviolet light, is observed. Hereinafter, such a gradation will be referred to as a temporal gradation, and a region exhibiting a temporal gradation will be referred to as a temporal gradation region. The region where the sea of ​​clouds 521a, 521b, and 521c overlap is the temporal gradation region that realizes the temporal gradation. The sea of ​​clouds 521a, 521b, and 521c overlap at the position indicated by the symbol P in Figures 4 and 5(c). The change in the expressed color at this position will be described.

[0060] The sea of ​​clouds 521a shown in FIG. 5(c) emits a yellow-orange light. The sea of ​​clouds 521a is formed by a second graphic layer 52 having a fluorescent material that emits a yellow-orange light when exposed to ultraviolet light. The sea of ​​clouds 521b shown in FIG. 5(c) emits an orange light. The sea of ​​clouds 521b is formed by a second graphic layer 52 having a phosphorescent material that emits an orange light when exposed to ultraviolet light. The orange-emitting phosphorescent material emits phosphorescence a predetermined time, for example, 30 seconds, after ultraviolet light irradiation has begun. The orange-emitting phosphorescent material continues to emit phosphorescence for a predetermined time, for example, approximately 30 seconds, after ultraviolet light irradiation has ceased. The sea of ​​clouds 521c shown in FIG. 5(c) emits a red light. The sea of ​​clouds 521c is formed by a second graphic layer 52 having a phosphorescent material that emits red light when exposed to ultraviolet light. The red-emitting phosphorescent material emits phosphorescence after a longer time has elapsed since irradiation with ultraviolet light than the orange-emitting phosphorescent material. The red-emitting phosphorescent material emits phosphorescence after removal of ultraviolet light than the orange-emitting phosphorescent material. The red-emitting phosphorescent material emits phosphorescence, for example, one minute after irradiation with ultraviolet light. The red-emitting phosphorescent material emits phosphorescence, for example, for about one minute after removal of ultraviolet light.

[0061] The above describes the configuration of the illuminated object 5c as an example, but the other illuminated objects 5a, 5b, 5d, and 5e also have similar configurations, such as a base material 50, a first graphic layer 51, and a second graphic layer 52, although the designs are different.

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

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

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

[0065] In addition, the controller parent unit 1 can control the illumination of the illuminated object 5, for example, so as to maintain the illumination of the second illumination light 22 in an off state when the illumination of the first illumination light 21 is in a first state, and to maintain the illumination of the second illumination light 22 in an on state when the illumination of the first illumination light 21 is in a third state.

[0066] In addition, the controller parent unit 1 can control the illumination of the illuminated object 5 so that the second illumination light 22 is turned on when the illumination of the first illumination light 21 is in the second state and turned off when the illumination of the first illumination light 21 is in the fourth state.

[0067] In addition, the controller parent unit 1 can control the second lighting lamp 22 so that the lighting of the first lighting lamp 21 gradually turns on when the lighting of the first lighting lamp 21 is in the second state and gradually turns off when the lighting of the first lighting lamp 21 is in the fourth state.

[0068] The controller master unit 1 may perform control so as to repeat the first to fourth states. That is, the first state may start again after the fourth state. Furthermore, the periods during which the first state is maintained, the second state, the third state, and the fourth state are all consistent within a range of ±5 seconds, preferably within a range of ±3 seconds, and preferably identical.

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

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

[0071] The master controller 1 can also execute time-delay control, which performs lighting control (individual control) on the illuminated objects 5a to 5e at different times. For example, the start timing of the first state of the first illuminators 21 of the illuminated objects 5a to 5e may be delayed by a predetermined time (e.g., 90 seconds). Even in this time-delay control, the periods for maintaining the first state, the second state, the third state, and the fourth state are consistent within a range of ±5 seconds, preferably within a range of ±3 seconds, and preferably identical.

[0072] In the time difference control, there is no particular limitation on the number of illuminated objects 5a to 5e. In this embodiment, five paintings are the illuminated objects 5a to 5e. An example of time difference control for these 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 lighting control for multiple illuminated objects 5a to 5e under time-delay control. FIG. 6 shows an example in which lighting control is performed with a time delay (90 seconds) to change the lighting state from the first state to the fourth state in the order of illuminated object 5a, illuminated object 5b, illuminated object 5c, illuminated object 5d, and illuminated object 5e. For illuminated object 5a, for which lighting control is started first, 180 seconds have already passed since the start of lighting control. For illuminated object 5b, for which lighting control is started next after illuminated object 5a, 90 seconds have passed since the start of lighting control. For illuminated object 5c, lighting control has just begun. For illuminated object 5d, lighting control begins 90 seconds after this state, and for illuminated object 5e, lighting control begins 180 seconds after this state. In this example, lighting control for illuminated objects 5a to 5e is performed with a time delay of 90 seconds. Therefore, the lighting state of the last illuminated object 5e starts to change 360 ​​seconds after the lighting control for the first illuminated object 5a starts.

[0074] The time difference control may be set to start lighting control in the order of illuminated object 5e, illuminated object 5d, illuminated object 5c, illuminated object 5b, and illuminated object 5a. Also, instead of starting lighting control in the order of illuminated objects 5a to 5e, lighting control may be started sequentially from the center to the adjacent objects on either side. In this way, the order of time difference control is not particularly limited.

[0075] In addition, the controller parent unit 1 may perform time difference control so that the relationship N×A=B holds when the number of paintings, etc. 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.

[0076] In addition to lighting control, the controller master unit 1 also controls sound using the sound device 4. Sound control may be linked to the lighting state of the lighting control, or may be controlled independently and individually 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 control the playback of sound sources corresponding to each state or combination of the first, second, third, and fourth states of the first light 21 and the second light 22. In this way, the controller master unit 1 can control the timing and volume of sound output.

[0077] <Example of 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 this embodiment. The remote control device 6 is, for example, an information processing terminal such as a smartphone, a wearable device, or a tablet. When the remote control device 6 executes an application software program, the operation image shown in Fig. 7 is displayed on the display unit of the remote control device 6.

[0078] 7, the remote control device 6 includes a multiple lighting control instruction unit 61, an individual lighting control instruction unit 62, and a sound source playback 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 control and sound control.

[0079] The multiple lighting control instruction unit 61 is a designation unit for causing the controller master unit 1 to execute lighting control for the multiple illuminated objects 5a to 5e. The multiple lighting control instruction unit 61 has a synchronization instruction unit 611 and a time difference instruction unit 612.

[0080] The synchronization instruction unit 611 is a designation means for instructing the above-mentioned synchronization control, which changes the illumination states of the plurality of illuminated objects 5a to 5e all at the same time in a 90-second cycle, to the controller master unit 1. The synchronization instruction unit 611 includes buttons for designating on / off of synchronization control, starting synchronization control, pausing synchronization control, and resetting (stopping) synchronization control.

[0081] The time difference instruction unit 612 is a designation means for instructing the master controller 1 to perform the above-mentioned time difference control, which sequentially starts lighting control for a plurality of illuminated objects 5a to 5e at time differences in 90-second cycles. The time difference instruction unit 612 includes a button for instructing time difference control in the order of illuminated object 5a, illuminated object 5b, illuminated object 5c, illuminated object 5d, and illuminated object 5e, and a button for instructing time difference control in the order of illuminated object 5e, illuminated object 5d, illuminated object 5c, illuminated object 5b, and illuminated object 5a.

[0082] The lighting individual control instruction unit 62 is a designation means for causing the controller master unit 1 to execute the above-described individual control that changes the lighting state of each of the illuminated objects 5a to 5e in a 90-second cycle. The lighting individual control instruction unit 62 has 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. 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 all include buttons for designating control on / off, starting synchronous control, pausing synchronous control, and resetting (stopping) synchronous control. By operating each of the instruction sections of the individual lighting control instruction section 62, individual lighting control (individual control) is executed for each of the illuminated objects 5a to 5e.

[0083] As described above, the remote control device 6 can specify three types of lighting control patterns to the controller master unit 1.

[0084] The sound source playback instruction unit 63 is a designation means for causing the controller master unit 1 to execute sound 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 removable media 20a, such as an SD card, inserted into the drive 20, and controls the output signal based on the sound source information to be output from the speaker 42 via the amplifier 41 of the audio device 4.

[0085] In this embodiment, lighting control and sound control operate independently, so that while a sound source such as music is playing, the lighting operation (lighting control) can be switched from multiple control (synchronous control or time-delay control) to individual control.

[0086] The above describes one embodiment of the present invention. Next, a description will be given of modified examples of configurations different from the above embodiment. In the following description, the same reference numerals will be used to designate components that are common to or similar to the above embodiment, and detailed descriptions thereof may be omitted.

[0087] Next, modified examples of the first illuminating lamp 21 and the second illuminating lamp 22 will be described. The illumination by the first illuminating lamp 21 of adjacent illuminated objects 5a to 5e may be in opposite directions. That is, the first illuminating lamp 21 corresponding to the first illuminated object 5a may be disposed below the first illuminated object 5a, and the first illuminating lamp 21 corresponding to the second illuminated object 5b may be disposed above the second illuminated object 5b. This reduces the possibility that the illumination of the first illuminating lamp 21 of the first illuminated object 5a will illuminate the second illuminated object 5b, or that the illumination of the first illuminating lamp 21 of the second illuminated object 5b will illuminate the first illuminated object 5a.

[0088] Furthermore, the illumination by the second illuminating lamp 22 of adjacent illuminated objects 5a to 5e may be in opposite directions. That is, the second illuminating lamp 22 of the first illuminated object 5a may be disposed below the first illuminated object 5a, and the second illuminating lamp 22 of the second illuminated object 5b may be disposed above the second illuminated object 5b. This reduces the possibility that the illumination of the second illuminating lamp 22 of the first illuminated object 5a will illuminate the second illuminated object 5b, or that the illumination of the second illuminating lamp 22 of the second illuminated object 5b will illuminate the first illuminated object 5a. In particular, care must be taken with the second illuminating lamp 22 to prevent its illumination from illuminating the adjacent illuminated objects 5a to 5e.

[0089] Furthermore, the number of illuminated objects 5a to 5e is not limited to five. For example, the illuminated object 5e can be omitted, and four paintings of the illuminated objects 5a to 5d can be used. In this case, when the four illuminated objects 5a to 5d are arranged from left to right, the first illuminating lamp 21 and / or the second illuminating lamp 22 of the rightmost illuminated object 5d can illuminate the painting or the like of the illuminated object 5d from the left, the first illuminating lamp 21 and / or the second illuminating lamp 22 of the leftmost illuminated object 5a can illuminate the illuminated object 5a from the right, and the first illuminating lamp 21 and / or the second illuminating lamp 22 of the second illuminated object 5c and the third illuminated object 5b from the right can illuminate them in opposite directions. Furthermore, the first illuminating lamp 21 and / or the second illuminating lamp 22 can illuminate all of the illuminated objects 5a to 5d or the centrally located illuminated objects 5c and 5b from above or below.

[0090] Furthermore, if there are four illuminated objects 5a to 5d, the relationship 4×A=B may be established in the time difference control, 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 this, when the first painting etc. (illuminated object 5a) is in the first state, the second painting etc. (illuminated object 5b) is in a state including the second state, the third painting etc. (illuminated object 5c) is in a state including the third state, and the fourth painting etc. (illuminated object 5d) is in a state including the fourth state; when the first painting etc. is in the second state, the second painting etc. is in a state including the third state, the third painting etc. is in a state including the fourth state, and the fourth painting etc. is in a state including the first state; when the first painting etc. is in the third state, the second painting etc. is in a state including the fourth state, the third painting etc. is in a state including the first state, and the fourth painting etc. is in a state including the second state; when the first painting etc. is in the fourth state, the second painting etc. is in a state including the first state, the third painting etc. is in a state including the second state, and the fourth painting etc. is in a state including the third state, which results in very beautiful synchronization control when viewed as a whole.

[0091] Furthermore, the heights of adjacent illuminated objects 5a-5e may be different from one another. With regard to the heights of adjacent illuminated objects 5a-5e, the height of a painting or the like illuminated from below among the illuminated objects 5a-5e may be higher than the height of a painting or the like illuminated from above among the illuminated objects 5a-5e. By doing so, it is possible to further reduce the illumination of adjacent paintings or the like.

[0092] Furthermore, the arrangement of the illuminated objects 5a-5e may be such that the positional relationships between the illuminated objects 5a-5e have a metaphorical expression. The metaphorical positional relationships between the illuminated objects 5a-5e mean that the things drawn on each of the illuminated objects 5a-5e and the arrangement of each of the illuminated objects 5a-5e give the viewer a specific image. The arrangement of the illuminated objects 5a-5e in which the positional relationships between the illuminated objects 5a-5e have a metaphorical expression may be such that, from left to right in front of the viewer, a painting of an ape-man (Australopithecus), a painting of a primitive man (Homo erectus), a painting of an archaic man (Homo neanderthalensis), a painting of a modern man (Homo sapiens), and a painting of a modern person are arranged in this order.

[0093] The arrangement of the illuminated objects 5a to 5e may also take into consideration the positional relationship between the viewer and the illuminated objects 5a to 5e. Taking into consideration the positional relationship between the viewer and the illuminated objects 5a to 5e means that what is depicted in each painting, etc., and the arrangement of each viewer and the illuminated objects 5a to 5e virtually create an environment surrounding the viewer.

[0094] Next, referring to Fig. 8, an example will be described in which the arrangement of illuminated objects 105a to 105h virtually creates an environment surrounding an observer. Fig. 8 is a plan view schematically showing a modified illuminated object appreciation system 100a. Note that Fig. 8 omits the illustration of some components, such as the controller master unit 1, amplifier 41, and remote control device 6.

[0095] 8, illuminated objects 105a to 105h may be arranged on a wall 110 or the like in a viewing room so as to surround a viewer S. Furthermore, lighting devices 2a to 2h corresponding to the illuminated objects 105a to 105h, respectively, may also be arranged so as to surround the viewer S.

[0096] For example, an illuminated object 105a depicting a coastal landscape may be placed in front of the viewer S. An illuminated object 105b depicting a seabird and a bridge may be placed to the right in front of the viewer S. An illuminated object 105c depicting a train station may be placed to the right of the viewer S. An illuminated object 105d depicting a rural area may be placed to the right behind the viewer S. An illuminated object 105e depicting a mountain may be placed behind the viewer S. An illuminated object 105f depicting a waterfall may be placed to the left behind the viewer S. An illuminated object 105g depicting a cliff may be placed to the left of the viewer S. An illuminated object 105h depicting a steamship may be placed to the left in front of the viewer S.

[0097] In this modification, the speakers 42a to 42h are also arranged to surround the viewer S. The controller master unit 1 performs acoustic control on each of the speakers 42a to 42h according to its position. 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 to the right of the viewer. The sound of small birds may be heard from the speaker 42d to the right rear of the viewer. The sound of wind blowing through trees may be heard from the speaker 42e behind the viewer. The sound of a waterfall may be heard from the speaker 42f to the left rear of the viewer. The sound of waves crashing against a cliff may be heard from the speaker 42g to the left of the viewer. The sound of a steam whistle may be heard from the speaker 42h in front of the left of the viewer.

[0098] The arrangement of the illuminated objects taking into consideration the positional relationship between the viewer and the illuminated objects is not limited to the above-described embodiment and modified examples. For example, the arrangement of the illuminated objects taking into consideration the positional relationship between the viewer and the illuminated objects may be such that the illuminated objects are arranged such that a painting of Enoshima Island is in front of the viewer, a painting of Mt. Fuji is to the right of the viewer, a painting of a coastal landscape is to the left of the viewer, and a painting of a lush mountain landscape is behind the viewer.

[0099] The controller master unit 1 controls the illumination of each of the illuminated objects 105a to 105h, such as paintings, with a time lag. The controller master unit 1 may also perform synchronized control, simultaneously controlling the illumination of each of the illuminated objects 105a to 105h, such as paintings. In other words, the illumination surrounding the viewer may simultaneously change from the first state to the second state, the third state, and the fourth state.

[0100] Furthermore, the controller master unit 1 may perform lighting control by associating the background on which the illuminated object is placed with the position of the illuminated object.

[0101] Next, an example of controlling lighting by associating a mural 210 as a background for arranging the illuminated objects 205a to 205d with the positions of the illuminated objects 205a to 205d will be described with reference to Fig. 9. Fig. 9 is a diagram showing a first example of arrangement 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, illuminated objects 205a to 205d are set against a background of a mural 210 of a world map. Note that the longitude and latitude lines on the world map may or may not be shown. Four illuminated objects 205a to 205d, such as paintings, are arranged on this mural 210. In this example, a first illuminated object 205a is arranged in the range of 90 to 180 degrees east longitude, a second illuminated object 205b is arranged in the range of 0 to 90 degrees east longitude, a third illuminated object 205c is arranged in the range of 0 to 90 degrees west longitude, and a fourth illuminated object 205d is arranged in the range of 90 to 180 degrees west longitude.

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

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

[0105] In this modified example, the master controller 1 executes normal lighting control so that the relationship 4×A=B holds, where A is the predetermined time difference and B is the time from the start of the first state to the end of the fourth state. This allows you to enjoy the morning, noon, evening, and night scenes from around the world.

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

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

[0108] The world map mural 210 does not have to be placed as a background, as viewers can imagine a world map even without the world map mural.

[0109] In the above embodiment and modified examples, the illumination of the first illuminating lamp 21 may be used to create the effect that the environment surrounding the viewer changes from morning to afternoon to evening to night.

[0110] In the above embodiment and modified examples, the first illuminating lamp 21 may be an interior light. In addition to the interior light, a first illuminating lamp 21 may be provided to individually illuminate the objects 5a to 5e and the objects 105a to 105h, such as paintings.

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

[0112] As described above, the illuminated object appreciation system 100 of this embodiment is an illuminated object appreciation system 100 (100a) including the controller master unit 1, the first illuminating light 21, the second illuminating light 22, the lighting control device 23, and a plurality of illuminated objects 5a to 5e (105a to 105h, 205a to 205d) such as paintings that are to be illuminated, and the controller master unit 1 is capable of controlling at least the lighting control device 23, and the lighting control device 23 is capable of controlling the illumination of the illuminated objects 5a to 5e by the first illuminating light 21 and also the illumination of the illuminated objects 5a to 5e by the second illuminating light 22, and the illumination of the illuminated objects 5a to 5e by the first illuminating light 21 is controlled by the illumination of the first illuminating light 21. The illumination of the first illuminating light 21 is controlled to include a first state in which the illumination of the first illuminating light 21 is maintained in a bright state, a second state in which the illumination of the first illuminating light 21 is gradually dimmed from the first state, a third state in which the illumination of the first illuminating light 21 is maintained in a dim state, and a fourth state in which the illumination of the first illuminating light 21 is gradually dimmed from the third state, the second illuminating light 22 is controlled to be turned on when the illumination of the first illuminating light 21 is in the second state and to be turned off when the illumination of the first illuminating light 21 is in the fourth state, and the controller master unit 1 can individually control the illumination of each of the illuminated objects 5a to 5e, and the individual control of the illumination of each of the illuminated objects 5a to 5e is control to stagger the start timing of the first state of the first illuminating light 21 of each of the illuminated objects 5a to 5e.

[0113] As a result, the start timing of the lighting control for each of the multiple illuminated objects 5a-5e is staggered, allowing the viewer to have a more realistic viewing experience of the illuminated objects 5a-5e, even in a large space. By controlling the lighting of multiple illuminated objects 5a-5e, such as paintings, with a single controller master unit 1 and devising the arrangement of the paintings, etc. and the lighting, it is possible to provide an illuminated object viewing system 100 that is particularly suitable for relatively large spaces. By viewing multiple lighting devices 2a-2h for paintings, etc. in synchronization, it is possible to control the atmosphere of the entire relatively large space, such as a museum or restaurant.

[0114] In addition, in this embodiment, the individual control of the lighting of each illuminated object 5a to 5e is a control that starts the first state of the first illumination lamp 21 of each illuminated object 5a to 5e with a predetermined time difference (90 seconds).

[0115] As a result, the illumination state of each of the illuminated objects 5a to 5e changes regularly at predetermined time intervals, thereby reducing the sense of incongruity felt by the changes and further improving the viewer's sense of immersion.

[0116] In addition, this embodiment further includes controller slave units 7 a to 7 e that transmit control information from the controller master unit 1 to the lighting control device 23 .

[0117] This allows the controller master unit 1 to 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 accommodate various layouts of the illuminated objects 5a to 5e.

[0118] In addition, in this embodiment, multiple lighting control devices 23 are arranged corresponding to each of the illuminated objects 5a to 5e, and multiple controller sub-devices 7a to 7e are arranged corresponding to each of the lighting control devices 23, and a first controller sub-device 7a, which is one of the multiple controller sub-devices 7a to 7e, is connected to a controller main device 1, the first controller sub-device 7a is connected to a second controller sub-device 7b, and the second controller sub-device 7b is connected to a third controller sub-device 7c, and control information from the controller main device 1 to the second controller sub-device 7b is transmitted via the first controller sub-device 7a, and control information from the controller main device 1 to the third controller sub-device 7c is transmitted via the first controller sub-device 7a and the second controller sub-device 7b.

[0119] This allows the master controller 1 to control the lighting of the lighting control device 23 via the multiple slave controllers 7a to 7e without complicating the control system.

[0120] In addition, in this embodiment, the controller parent unit 1 can select synchronization control, which synchronizes the start timing of the first state of the first lighting lamp 21 of each illuminated object 5a to 5e, instead of control that shifts the start timing (time difference control).

[0121] This allows for selection of synchronization control in accordance with the type of illuminated object 5a to 5e, thereby providing the viewer with a viewing experience that is more suited to the illuminated object 5a to 5e.

[0122] In this embodiment, the illuminated object appreciation system 100 further includes an audio device 4 that outputs sound, and the controller master unit 1 controls the audio device 4 to output sound.

[0123] This allows sound from the sound device 4 to be added in addition to lighting control, providing a viewing experience that appeals more to the viewer's senses.
