Background Art

[0002] Photochromic materials whose structure changes upon irradiation with light and whose color changes are known. For example, when a photochromic material is irradiated with ultraviolet rays in a transparent state, it develops color. Then, when the photochromic material is irradiated with visible light in the colored state, it returns to the transparent state. Conventionally, techniques for performing writing and erasing using a photochromic compound have been proposed.

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, referring to FIG. 1, an overview of a color conversion system according to a first embodiment of the present invention will be described. FIG. 1 is a diagram showing a schematic configuration of a color conversion system according to a first embodiment of the present invention.

[0010] As shown in FIG. 1, the color conversion system according to the first embodiment of the present invention is a color conversion system that converts the color of a decoration (predetermined medium) such as the windshield glass 42 of a clock 4.

[0011] The color conversion system is configured such that a lighting device 2 that illuminates the windshield glass 42 of the clock 4 and a mobile terminal 1 that controls the lighting device 2 are interconnected via a wireless communication network such as Bluetooth. Note that Bluetooth is a registered trademark.

[0012] The lighting device 2 is operated by, for example, a store operator or the like, and the power is turned on or off. The lighting device 2 activated by turning on the power is controlled by the mobile terminal 1 to irradiate ultraviolet light (UV light) or visible light onto a predetermined medium disposed at a predetermined position within the device.

[0013] In general, ultraviolet rays have a shorter wavelength than visible light and refer to electromagnetic waves in the range of 10 to 380 nm. Those with a wavelength longer than 380 nm are called visible light. The region (range) of 300 nm to 380 nm can be said to be the boundary area between ultraviolet rays and visible light.

[0014] Examples of the predetermined medium include, in addition to watches, various ornaments such as nails, glasses, jewelry, contact lenses, shoes, bags, vehicles, etc. The configuration of the lighting device 2 corresponding to each ornament will be described later.

[0015] The portable terminal 1 is managed by an operator of a store or the like. The portable terminal 1 executes various processes while controlling the light emission operation of the lighting device 2.

[0016] FIG. 2 is a block diagram showing the hardware configuration of the portable terminal in the color conversion system of FIG. 1.

[0017] The portable terminal 1 includes a CPU (Central Processing Unit) 11, 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.

[0018] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 to the RAM 13. In the RAM 13, data and the like necessary for the CPU 11 to execute various processes are also appropriately stored.

[0019] 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. The output unit 16, input unit 17, storage unit 18, communication unit 19, and drive 20 are connected to the input / output interface 15.

[0020] The output unit 16 is composed of a display, a speaker, etc., and outputs various information as images and sounds. The input unit 17 is composed of a keyboard, a mouse, etc., and inputs various information.

[0021] The storage unit 18 is composed of a hard disk, a DRAM (Dynamic Random Access Memory), etc., and stores various data. The communication unit 19 communicates with other devices (the lighting device 2 in the example of FIG. 1) via a wireless communication network.

[0022] A removable medium 21 made of a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, etc. is appropriately mounted on the drive 20. The program read from the removable medium 21 by the drive 20 is installed in the storage unit 18 as necessary. Also, the removable medium 21 can store various data stored in the storage unit 18 in the same manner as the storage unit 18.

[0023] FIG. 3 is a block diagram showing the functional configuration of the mobile terminal having the hardware configuration of FIG. 2, the configuration of the lighting device 2, and the structure of a predetermined medium in the color conversion system of FIG. 1. As shown in FIG. 3, this color conversion system includes a lighting device 2, a color conversion layer 60 disposed on the surface or inside the glass of the windscreen 42 of the clock 4 as a predetermined medium, and a mobile terminal 1. In the case of this color conversion system, the mobile terminal 1 controls the irradiation of visible light and UV light of the lighting device 2, and the lighting device 2 irradiates the visible light and UV light to the windscreen 42 of the clock 4 based on the control from the mobile terminal 1. A color conversion layer 60 is disposed on the surface of the windscreen 42, and by irradiating the UV light and visible light in order, the color of the color conversion layer 60 changes (after coloring, fading), so that the colorless and transparent windscreen 42 under the color conversion layer 60 also changes to colored and transparent.

[0024] First, the functional configuration of the mobile terminal 1 will be described. As shown in FIG. 3, in a region of the storage unit 18 of the mobile terminal 1 (see also FIG. 2), color information, light source control information, etc. are stored. The color information is information that associates the color displayed on the UI (User Interface: for example, the screen of the mobile terminal 1 where the color selection button area 151 in FIG. 15 is arranged) where the user designates a color with the light source control information.

[0025] The light source control information is information (parameter values in FIG. 16) that parameterizes the applied voltages for driving the UV light source 55 and the LED light sources 56a, 56b, 56c of the lighting device 2 individually according to the color designated by the user on the UI, and information (number of seconds) including the light irradiation time of each light source. In FIG. 16, the preset parameter values are such that UV is, for example, 255, R (red) is 255, G (green) is 0, and B (blue) is 0.

[0026] In the CPU 11 of the mobile terminal 1, when controlling the color conversion operation of the lighting device 2, the UI providing unit 31 and the color conversion control unit 32 function.

[0027] The UI providing unit 31 provides the user with a UI (User Interface: for example, the screen of the mobile terminal 1 in FIGS. 15 and 16) for the user to perform a designation operation of designating a predetermined color from among a plurality of colors.

[0028] The screen of the mobile terminal 1 provided by the UI providing unit 31 (see FIGS. 15 and 16) has a specified color internal instruction area (color selection button area 151 in FIG. 15) that accepts a designation operation of instructing a predetermined color (for example, red) from among a predetermined N colors (for example, 8 colors) defined in advance, and a customization instruction area (customization area 161 in FIG. 16) that accepts a designation operation of customizing by the user to generate an arbitrary color and designating the generated color as a predetermined color. In addition, the UI providing unit 31 also provides a page for the user to create a color and a screen of a sales site where the color created by the user is sold to others.

[0029] The color conversion control unit 32 receives a predetermined color specified by a specified operation performed on the UI (see FIG. 15), and notifies the illumination device 2 of control information (light source control information) for converting a predetermined medium into the predetermined color. Specifically, when, for example, a "red" button is specified in the color selection button area 151 of the screen in FIG. 15, the color conversion control unit 32 transmits light source control information for controlling each of the LED light sources of various colors for the "red" button to the illumination device 2 to represent the color.

[0030] The color conversion control unit 32 irradiates the windshield glass 42 (strictly speaking, the color conversion layer 60) (predetermined medium) with ultraviolet rays (UV light) from the UV light source 55 of the illumination device 2 to cause the windshield glass 42 to develop color, and irradiates the windshield glass 42 with visible light of red, green, and blue from the respective LED light sources 56a, 56b, 56c of the illumination device 2 with light source control information (conditions such as light irradiation intensity and irradiation time) necessary for converting the visible light into a predetermined color, to fade the windshield glass 42, thereby executing control to convert the windshield glass 42 into a preset color (predetermined color).

[0031] Specifically, the color conversion control unit 32 transmits light source control information to the illumination device 2. In the illumination device 2, the communication unit 51 receives the light source control information transmitted from the mobile terminal 1 and passes it to the light source drive unit 52. The light source drive unit 52 drives the UV light source 55 and the LED light sources 56a, 56b, 56c based on the light source control information to irradiate light from each of them.

[0032] The light source control information is the parameter value of the applied voltage and the irradiation time for each color. The parameter value of the applied voltage divides the range from 0 (minimum) to 255 (maximum) up to the maximum voltage capable of driving the light source, and any value within that range is sent. The light source drive unit 52 applies a voltage corresponding to the parameter value to the above light source to drive the light source to emit light. The irradiation time is the time during which each color light source irradiates the medium with light, and is, for example, in seconds.

[0033] Subsequently, the configuration of the illumination device 2 will be described. The lighting device 2 includes a communication unit 51, a light source driving unit 52, a power supply unit 53, a housing for housing the clock 4, an ultraviolet light source (hereinafter referred to as "UV light source 55"), and LED light sources 56a, 56b, 56c as visible light sources. In the following, when it is not necessary to distinguish and explain each of the LED light sources 56a, 56b, 56c, they are referred to as the LED light source 56. The lighting device 2 includes an openable lid and a case. The UV light source 55 and the LED light sources 56a, 56b, 56c are arranged on the back surface of the lid. In the case, for example, the clock 4 is housed as a predetermined medium. The lighting device 2 irradiates the windshield glass 42 inside the case with the lid closed so that external light does not enter, with UV light from the UV light source 55 and visible light of red, green, and blue from each of the LED light sources 56a, 56b, 56c.

[0034] The communication unit 51 receives light source control information by communicating with the mobile terminal 1. The light source driving unit 52 controls the UV light source 55 and the LED light source 56 based on the light source control information received from the mobile terminal 1. Specifically, the light source driving unit 52 individually drives each of the LED light sources 56a, 56b, 56c based on the light source control information (drives by individually changing the applied voltage, irradiation time, etc.). The power supply unit 53 supplies power to each part of the lighting device 2.

[0035] Although not shown in FIG. 3, for example, it may be configured to have an optical system including a lens, a mirror, a mask, or the like. In this case, the mask is for forming an image on the photochromic layer 61, for example, an optical mask or the like, and is arranged between the opening of the housing and the UV light source and the LED light source. The optical mask is, for example, one in which a chromium layer is patterned on an optical glass. In addition to the LED light source, a laser light source may be used as the visible light source. When using a laser light source, the lighting device 2 may be configured such that the laser light source scans the laser light at high speed without using a mask.

[0036] On the upper surface of the main body of the timepiece 4, a windshield glass 42 is provided. The windshield glass 42 has a color conversion layer 60 on its surface (upper surface). Before processing, the color conversion layer 60 is colorless and transparent, and the dial of the timepiece 4 can be seen through. The color conversion layer 60 includes a photochromic layer 61 disposed on the windshield glass 42 and a coating layer 62 disposed on the photochromic layer 61. Since the coating layer 62 is the outermost layer and is exposed to the outside, it is exposed to all daily light including sunlight. The color conversion layer 60 is a layer that colors or fades (decolors) upon irradiation with the above-mentioned UV light and visible light, and is a layer that contributes to color conversion. After any color is realized in the color conversion layer 60, it can be exposed to natural light, particularly sunlight including visible light and UV light. In any photochromic material, fading due to visible light with a sunlight-level intensity can be suppressed for a predetermined period. The predetermined period is, for example, from 1 day to 2 days (about 1 week depending on the medium and the usage environment of the medium).

[0037] The coating layer 62 has a UV light absorption wavelength region (for example, from 325 nm to 430 nm) and passes the UV light for coloring (for example, wavelength 325 nm). The end of the absorption band of the coating layer 62 coincides with the wavelength of the UV light for coloring at 325 nm. Specifically, the coating layer 62 absorbs UV light in a predetermined ultraviolet wavelength range. For example, it absorbs UV light in the wavelength range from ultraviolet wavelength Anm to ultraviolet wavelength Bnm. For example, Anm is 325 nm and Bnm is 430 nm. Since the absorption at the absorption end of the coating layer 62 is not 100%, at least a part of the UV light for coloring passes through the coating layer 62.

[0038] On the other hand, the coating layer 62 absorbs the UV light contained in sunlight (325 nm or more at the earth's surface). At least most of the UV light (for example, from 325 nm to 430 nm) that promotes coloring due to sunlight is not irradiated to the display portion where coloring and fading have occurred, and the display color of the color conversion layer 60 is maintained.

[0039] Since the coating layer 62 absorbs UV light in this wavelength range, the UV light in this wavelength range is prevented from reaching the photochromic layer 61, and the color development is suppressed. As described above, even when the color conversion layer 60 is exposed to sunlight, the color development and fading are suppressed, and the color realized in the color conversion layer 60 is maintained.

[0040] The photochromic layer 61 is transparent before UV light irradiation. The photochromic layer 61 has three types of photochromic materials that respectively develop colors into cyan that absorbs red, magenta that absorbs green light, and yellow that absorbs blue light when irradiated with UV light.

[0041] The photochromic material fades to transparency when irradiated with visible light. The photochromic material that develops cyan fades to transparency when irradiated with red light. The photochromic material that develops magenta fades to transparency when irradiated with green light. The photochromic material that develops yellow fades to transparency when irradiated with blue light. However, fading due to visible light with a sunlight-level intensity is suppressed for a predetermined period in any of the photochromic materials. The photochromic material can absorb light with a wavelength shorter than the ultraviolet wavelength Anm, and when irradiated with light with a wavelength shorter than the ultraviolet wavelength Anm, it develops color.

[0042] The photochromic layer 61 has three types of photochromic materials that respectively develop colors into yellow, magenta, and cyan when irradiated with UV light and visible light from the lighting device 2. The photochromic layer 61 is transparent before UV light irradiation. The photochromic layer 61 has three types of photochromic materials that respectively develop colors into cyan that absorbs red, magenta that absorbs green light, and yellow that absorbs blue light when irradiated with UV light.

[0043] When the photochromic material is irradiated with visible light, it fades to transparency. A photochromic material that develops a cyan color fades to transparency when irradiated with red light. A photochromic material that develops a magenta color fades to transparency when irradiated with green light. A photochromic material that develops a yellow color fades to transparency when irradiated with blue light. However, in any photochromic material, fading due to visible light with a sunlight-level intensity can be suppressed for a predetermined period.

[0044] When the coating layer 62 is irradiated with UV light containing light with a wavelength shorter than the ultraviolet wavelength Anm, the coating layer 62 does not absorb the UV light. Therefore, the UV light reaches the photochromic layer 61. The photochromic layer 61 reacts to the UV light and changes to cyan, magenta, and yellow colors. Cyan, magenta, and yellow are mixed to achieve black or achromatic color. Although it is described as black or achromatic color, it is not necessarily a complete black or complete achromatic color.

[0045] The red, green, and blue visible light irradiated from the lighting device 2 is irradiated onto the color conversion layer 60 that has developed a black color based on a predetermined irradiation intensity, irradiation intensity ratio for each color, and irradiation time. Specifically, by adjusting the irradiation intensity of red, green, and blue visible light, the irradiation intensity ratio for each color, and the irradiation time, each color of cyan, magenta, and yellow can be faded. By varying the degree of fading of each color of cyan, magenta, and yellow, any color can be realized.

[0046] The coating layer 62 transmits visible light. Therefore, red, green, and blue light reaches the photochromic layer 61. In order to output visible light in a narrow band of each color, for example, an LED with a narrow half-value width of 5 to 10 nm is used as the visible light source.

[0047] For example, red light selectively fades a photochromic material that has developed a cyan color, and the degree of fading of magenta and yellow colors is smaller than the degree of fading of cyan color. Green light selectively fades the photochromic material that has developed a magenta color, and the degree of fading of cyan and yellow colors is smaller than that of fading the magenta color. Blue light selectively fades the photochromic material that has developed a yellow color, and the degree of fading of cyan and magenta colors is smaller than that of fading the yellow color.

[0048] In the example of the clock 4 shown here, the photochromic layer 61 is arranged on the windshield glass 42, but the photochromic layer 61 may be included inside the windshield glass 42.

[0049] Hereinafter, the operating principle of the color conversion system will be described with reference to FIGS. 4 to 13. First, the light source and the characteristics (wavelength) of light will be described with reference to FIG. 4. FIG. 4 is a diagram showing the light source and the characteristics (wavelength) of light of the lighting device in FIG. 3. The UV light source 55 shown in FIG. 3 is a light source that irradiates ultraviolet light, and for example, a high-pressure mercury lamp, a low-pressure mercury lamp, an ultraviolet LED, an ultraviolet laser, etc. are used. The UV light emitted by the UV light source 55 includes, for example, UV light 71 with a wavelength of 325 nm. When an ultraviolet LED is used as the UV light source 55, the ultraviolet LED emits UV light 71 (see FIG. 4) having a center wavelength of 325 nm ± 5 nm to ± 10 nm. This UV light 71 has a half-value width of ± 5 nm to ± 10 nm.

[0050] The visible light source shown in FIG. 3 includes an LED light source 56a that emits green light, an LED light source 56b that emits blue light, and an LED light source 56c that emits red light. The LED light source 56a emits, for example, blue visible light 74 (see FIG. 4) having a half-value width of 5 nm to 10 nm and a center wavelength of 430 nm ± 5 nm to ± 10 nm. The LED light source 56b emits, for example, green visible light 73 (see FIG. 4) having a half-value width of 5 nm to 10 nm and a center wavelength of 525 nm ± 5 nm to ± 10 nm. The LED light source 56c that emits red light emits visible light 72 (see FIG. 4) having a half-value width of, for example, 5 nm to 10 nm and a center wavelength of 650 nm ± 5 nm to ± 10 nm. The above wavelengths and half-value widths are not limited to these and can be appropriately redesigned.

[0051] FIG. 5 is a diagram showing the absorption spectrum of the photochromic material before UV light irradiation and the spectrum of the UV light to be irradiated. FIG. 6 is a diagram showing the absorption spectrum of the photochromic material after UV light irradiation. FIG. 7 is a diagram showing how the irradiation intensities of blue, green, and red light sources are adjusted for each color. FIG. 8 is a diagram showing the absorption spectrum absorbed by the coating layer after irradiating the color conversion layer with visible light by adjusting the irradiation intensity as shown in FIG. 7. Before UV light irradiation, for example, diarylethene is used as the photochromic material in the photochromic layer 61. As shown in FIG. 5, the photochromic material has an absorption spectrum 76 only in the UV light region and is transparent. On the other hand, the UV light irradiated from the UV light source 55 to the photochromic layer 61 is the spectrum 71 in FIG. 5.

[0052] When three types of photochromic materials that develop colors in yellow, magenta, and cyan are used as the photochromic material, the photochromic material that develops yellow has an absorption band at a blue wavelength. The photochromic material that develops magenta has an absorption band at a green wavelength. The photochromic material that develops cyan has an absorption band at a red wavelength.

[0053] Therefore, when using three types of photochromic materials that develop colors in yellow, magenta, and cyan, the photochromic materials after UV light irradiation develop colors in yellow, magenta, and cyan and change to black as a whole as shown in FIG. 6. In the graph of FIG. 6, the absorption spectra of the three colors of yellow, magenta, and cyan are shown in a simplified manner, but materials that are more complex, have a narrower half-value width, or have a wider half-value width can also be selected.

[0054] When irradiating visible light for fading with, for example, the LED light source 56 according to each absorption band of the photochromic material, as shown in FIG. 7, blue light with a central wavelength of, for example, 430 nm and a half-value width of 10 nm is irradiated from the blue LED. The blue light is absorbed by the photochromic material presenting yellow. Therefore, the photochromic material presenting yellow fades. The green light is absorbed by the photochromic material presenting magenta. And the photochromic material presenting magenta fades. The red light is absorbed by the photochromic material presenting cyan. And the photochromic material presenting cyan fades. By adjusting the irradiation intensity and irradiation time, as shown in FIG. 7, the fading degree of each color changes. In the example of FIG. 7, the intensity of the blue LED > the intensity of the red LED > the intensity of the green LED. In this case, the fading of yellow > the fading of cyan > the fading of magenta.

[0055] The absorption spectrum of the color conversion layer 60 after visible light is irradiated at the irradiation intensity of FIG. 7 is as shown in FIG. 8. As for the magnitudes of the color conversion layer 60 absorbing green, red, and blue colors respectively, the absorption of green > the absorption of red > the absorption of blue. From this, as the display color, blue is strong, followed by red, and green is the lowest. As a result of each of the three colors being absorbed, a blue-violet display is realized.

[0056] FIG. 9 is a diagram showing the absorption spectrum of a photochromic material exhibiting cyan after color development and fading, the absorption spectrum of the coating layer, and the spectrum of sunlight on the ground.

[0057] The absorption spectrum of the photochromic material exhibiting cyan after color development and fading becomes the absorption spectrum 78 shown in FIG. 9. Also, the absorption spectrum of the coating layer 62 becomes the absorption spectrum 75. The spectrum of sunlight on the ground surface is the spectrum 79.

[0058] The absorption spectrum of the photochromic material exhibiting cyan after color development and fading has an absorber in the ultraviolet region. This is because a part of the photochromic material exhibiting cyan returns to the state before UV light irradiation by the irradiation of visible light (red light).

[0059] Sunlight on the ground surface has UV light and overlaps with the absorption band (from 325 nm to 430 nm) resulting from the structure of the photochromic material exhibiting cyan before UV light irradiation. That is, by being exposed to the ultraviolet rays contained in sunlight, the photochromic material may be colored.

[0060] The coating layer 62 eliminates this possibility. The reason is that the coating layer 62 absorbs light from 325 nm to 430 nm which may be adversely affected by the ultraviolet rays of sunlight. Due to the absorption in the coating layer 62, the ultraviolet rays of sunlight do not reach the photochromic layer 61, and the state of the photochromic layer 61 is maintained. As a result, the colored and faded photochromic layer 61 maintains its state, and the display color realized by color development and fading is maintained.

[0061] Here, returning to FIG. 4, the UV light for color development will be additionally explained. Since the UV light for color development is irradiated onto the coating film on which the coating layer 62 is formed, it is preferably not absorbed by the coating layer 62.

[0062] However, when simply shortening the wavelength of the UV light, since the energy value is high, it has an adverse effect on, for example, the skin. Therefore, it is preferable that the wavelength of the UV light for color development is as long as possible. Further, the wavelength of the UV light for color development is preferably provided close to or partially overlapping with the short wavelength side of the absorption band of the coating layer 62.

[0063] For example, in the example shown in FIG. 4, the coating layer 62 absorbs UV light from 325 nm to 430 nm, and the UV light for color development has a wavelength of 325 nm, which is the same as the wavelength at the end of the absorption of the coating layer 62. Although a part of the UV light for color development is absorbed by the coating layer 62, by providing sufficient intensity for color development, the UV light for color development can cause the photochromic layer 61 to develop color without problems.

[0064] FIG. 10 is a diagram showing an example in the case where, for example, diarylethene is used as the photochromic material of the photochromic layer that realizes cyan, magenta, and yellow. As the photochromic material of the photochromic layer that realizes cyan, magenta, and yellow, for example, the diarylethene shown in FIG. 10 may be used.

[0065] FIG. 11 is a diagram showing a photochromic material that exhibits yellow. As the photochromic material that exhibits yellow, the one shown in FIG. 11 can be used.

[0066] FIG. 12 is a diagram showing a photochromic material that exhibits magenta. As the photochromic material that exhibits magenta, the one shown in FIG. 12 can be used.

[0067] FIG. 13 is a diagram showing a photochromic material that exhibits cyan. As the photochromic material that exhibits cyan, the one shown in FIG. 13 can be used. Note that the examples of the photochromic materials shown here are just examples, and the photochromic materials are not limited to those described above. For diarylethene, the colors that develop by adding various functional groups can be appropriately designed. Also, the photochromic materials are not limited to diarylethene, and any known photochromic materials can be applied.

[0068] Here, with reference to FIGS. 14 to 16, the operation of the color conversion system having the functional configuration of FIG. 3 will be described. FIG. 14 is a flowchart showing the operation of the color conversion system having the functional configuration of FIG. 3. FIG. 15 is a diagram showing an example of the color specification screen (UI) of the mobile terminal of FIG. 3. FIG. 16 is a diagram showing an example of the color setting screen (UI) of the mobile terminal of FIG. 3.

[0069] When causing the lighting device 2 storing the clock 4 to execute the color conversion operation, the user can display the color specification screen shown in FIG. 15 by performing a display operation of the color specification screen on the mobile terminal 1. The color specification screen, color setting screen, etc. displayed on the mobile terminal 1 are referred to as UI (User Interface).

[0070] As a method of displaying the color specification screen on the mobile terminal 1, for example, there is a first method in which an application program for color conversion processing (hereinafter referred to as "app") is installed in advance in the mobile terminal 1, and the app is started by clicking the icon of the color conversion app displayed on the top screen of the mobile terminal 1 to display the color specification screen.

[0071] Alternatively, there may be a second method in which, from the browser of the mobile terminal 1, access is made to the website of the color conversion service provided by the service provider to display the color specification screen provided by the website.

[0072] On the color specification screen of FIG. 15, a color selection button area 151 is arranged. In the color selection button area 151, color selection buttons such as UV, red, yellow, purple, magenta, orange, blue, green, and gray are arranged. The user can select a desired color from the button group in the color selection button area 151 and click the button to specify the color of the windscreen 42 (see FIG. 1) of the clock 4.

[0073] In the color specification screen of FIG. 15, when there is no desired color or when creating a different color from the default color, by clicking the "Color Settings" button in the color specification screen of FIG. 15, the color setting screen shown in FIG. 16 is displayed.

[0074] On the color setting screen of FIG. 16, a customization area 161 is arranged. The customization area 161 is a customization instruction area that accepts a designation operation in which the user customizes to generate an arbitrary color and designates the generated color as a predetermined color. Specifically, in the customization area 161, input windows 162 for changing the parameter values of UV, R (red), G (green), and B (blue) respectively, an input window 163 for specifying the irradiation time, etc. are provided. In addition, there is also an input field for specifying the ratio of three colors. In the input window 162, parameter values for the irradiation intensity (voltage values applied to the respective light sources of red, green, and blue) can be set between 0 and 255. 0 is the minimum value and 255 is the maximum value.

[0075] As shown in FIG. 14, in step S101, when on the user's mobile terminal 1, an operation is performed to indicate a desired color (for example, red) from among a predetermined N colors (for example, 8 colors) on the color specification screen, the UI providing unit 31 accepts the color specification.

[0076] When the color is specified, the mobile terminal 1 controls the lighting device 2 to start the lighting operation. In this case, in step S102, first, by irradiating UV light from the UV light source 55, the color conversion layer 60 on the surface of the windshield glass 42 of the clock 4 is caused to develop color.

[0077] Specifically, on the color designation screen of the mobile terminal 1, when a color is designated, the UI providing unit 31 receives the color designation, and the color information is passed to the color conversion control unit 32. Based on the color information, the color conversion control unit 32 reads out the corresponding light source control information from the storage unit 18 and transmits the light source control information to the lighting device 2. The light source control information includes UV light, parameter values of the irradiation intensities of visible lights of respective colors, and irradiation time. In addition, the light source control information also includes irradiation ratios of respective colors as required.

[0078] In the lighting device 2, the communication unit 51 receives the light source control information transmitted from the mobile terminal 1 and passes it to the light source driving unit 52. Based on the light source control information, the light source driving unit 52 drives the UV light source 55 to irradiate the clock 4 with UV light. At this time, the UV light is irradiated for an irradiation intensity and an irradiation time corresponding to the parameter values included in the light source control information.

[0079] Subsequently, in step S103, the light source driving unit 52 irradiates visible lights of red, green, and blue LED light sources 56a, 56b, and 56c of the lighting device 2 under conditions (irradiation intensities and irradiation times corresponding to the parameter values of the three LED light sources 56 included in the light source control information) necessary for converting the visible lights into a predetermined color, and fades the color conversion layer 60 of the windshield glass 42 of the clock 4, thereby executing control to convert the color conversion layer 60 of the windshield glass 42 of the clock 4 into the color designated by the user.

[0080] Here, a business model using the color conversion system of the first embodiment will be described. In the above embodiment, an example in which the three-layer color conversion layer 60 is formed on the surface of the windshield glass 42 of the clock 4 has been described. However, alternatively, in the dial of the clock 4, the color may be changed by using a UV-reactive transparent dye. The clock 4 has a three-layer structure, where the first layer of the top layer is a glass layer with a UV-cut function, the second layer is a dial layer containing a UV-reactive dye, and the third layer is the substrate layer of the clock 4.

[0081] Specifically, a clock 4 having a three-layer color conversion layer is provided. The top layer is the part of the windshield glass of the clock 4 having a UV-cut function, and a liquid agent that blocks specific UV light is kneaded or coated on the glass. The second layer is the dial, on which a colorless and transparent UV-reactive dye is processed. The third layer of the bottom layer is the substrate of the clock, which serves to support the dial. The user selects a color via the app of the mobile terminal 1 and irradiates UV light with the lighting device 2 (a dedicated UV irradiation device), thereby changing the colors of the dial and the second hand.

[0082] As a business model, a service is provided for changing the color of the dial of the clock 4 using a special UV-reactive transparent dye. In this case, the service provider sells colors to the user through a mobile application, the user selects and purchases a color through the mobile application, and the service provider temporarily changes the colors of the dial and the second hand with a color conversion system including the lighting device 2 (UV irradiation device) for the color purchased by the user. The color-changing state of the dial and the second hand is maintained for a period between 24 hours and one week and then returns to transparency.

[0083] In this service, the clock 4 is sold at least in one of an online store and a retail store, and a subscription model is also introduced. By regularly providing updates on new designs and colors, users can always enjoy new experiences. In particular, by selling limited models and collaboration models, diversification of revenue can be achieved. According to this service, a new experience can be provided to consumers who value fashion and personality.

[0084] As a marketing strategy, for example, this service can be penetrated into the market through partnerships with influencers and promotional activities at events. Also, by implementing user participation-based design contests and limited campaigns, brand engagement can be strengthened.

[0085] As described above, according to this first embodiment, the user can freely change the colors of the windshield glass 42 of the watch, the dial, the second hand, etc. That is, the decorative modification of the watch 4 according to the user's taste becomes possible. Thereby, for example, it becomes possible to customize the watch according to a specific event or daily fashion. Also, the UV cut function can prevent the deterioration of the internal parts of the watch and enable long-term use.

[0086] Also, according to this color conversion system, by processing a colorless and transparent UV-reactive dye on the dial and second hand of the watch, the color selected by the user temporarily changes by UV irradiation. The color conversion layer of the watch 4 has a three-layer structure, and the uppermost glass part is equipped with a UV cut function, which can prevent the harmful effects of UV light. Also, the second layer contains a UV-reactive dye, and the color specified by the user through the app of the mobile terminal 1 is colored on the dial and second hand by the irradiation of UV light and LED light from the lighting device 2 (a dedicated UV irradiation device). The colored color is maintained for 24 hours to one week and then returns to transparency, enabling use according to various situations.

[0087] As for the business targets, product lines and target markets are assumed. Product lines corresponding to a wide range of categories such as fashion watches, business watches, and sports watches can be developed. The target market ranges from young people sensitive to fashion to business people.

[0088] As for the sales channel and pricing strategy, it is assumed that sales will be made through the company's online store and major online marketplaces. Store sales will be mainly carried out through select shops and watch specialty stores. In addition, by setting a premium price and selling limited models, it is possible to maximize profits.

[0089] A subscription service that regularly provides new dial designs and colors on a monthly fee basis can be considered. With this service, special designs tailored to specific seasons or events can be provided, improving customer loyalty.

[0090] The services described above provide a new experience for users to customize the color of the dial of Watch 4 and can offer various options according to fashion and lifestyle. This is expected to provide a new way for users to express their individuality and enhance competitiveness in the market.

[0091] Next, a second embodiment (example of nails) of the color conversion system including the lighting device shown in FIG. 3 will be described with reference to FIGS. 17 to 19. First, the color conversion system including the lighting device of the second embodiment will be described with reference to FIG. 17. FIG. 17 is a diagram showing a second embodiment of the color conversion system including the lighting device shown in FIG. 3. The lighting device 2 of the second embodiment performs color conversion processing on nails that are applied to or attached to human fingernails. In the following embodiments, the color conversion layer applied to the medium shall use the two-layer color conversion layer 60 shown in FIG. 3 or the type of the three-layer nail 401 shown in FIG. 18 depending on whether the object to be colored is transparent or not. Also, the portable terminal 1 is the same as that shown in FIGS. 1 to 3 above, and its description will be omitted.

[0092] As shown in FIG. 17, in the lighting device 2 of the second embodiment, a handrest 172 is disposed on the side portion of the device main body. Further, a plurality of pins 173 are arranged in a zigzag pattern at predetermined intervals in an opening provided in the side portion of the device main body where the handrest 172 is disposed. The plurality of pins 173 are for inserting a finger 181 into the gap between the respective pins 173, that is, for fixing the length (finger position) in the depth direction in which the finger 181 enters the case. Thereby, the position of the claw 182 is also fixed in a state where the respective fingers are separated.

[0093] In this lighting device 2, light sources (UV light source 55 and LED light source 56) are disposed inside the case above the positions of the respective claws 182. Since the position of the claw 182 is automatically fixed simply by a person inserting a finger into the gap between the pins 173 (without manually moving the hand for alignment), the light from the light source can be evenly irradiated onto each claw 182, and the nail 401 disposed on the surface of the claw 182 can be colored.

[0094] Here, the nail 401 will be described with reference to FIG. 18. FIG. 18 is a diagram schematically showing the laminated structure of the nail applied to the fingernail of the finger which is the object (predetermined medium) of color conversion by the lighting device of FIG. 17. FIG. 19 is a diagram showing the absorption spectrum of the UV absorber, the spectrum of the lighting for coloring the photochromic layer, and the absorption spectrum of the polymerization initiator of the visible light curable resin. As shown in FIG. 18, when the predetermined medium is, for example, the nail 401 applied to the fingernail 182 of a person's finger 181, as shown in FIG. 18, it has a three-layer structure laminated in the order of a base layer 63, a photochromic layer 61, and a coating layer 64 from the side closer to the nail 182. That is, in this second embodiment, the base layer 63 is disposed between the photochromic layer 61 and the nail 182, and the nail 401 itself functions as a color conversion layer.

[0095] The base layer 63 is mainly made of, for example, an ultraviolet-curable resin and is a white coating film. The base layer 63 shields the color of the nail 182 (the object to be coated) and suppresses the color mixing of the color of the photochromic layer 61 and the color of the surface of the nail 182. Since the nail 182 is almost pink, by disposing the base layer 63 between the color of the nail 182 (pink) and the photochromic layer 61, it is possible to suppress the color mixing of the pink color of the nail 182 with a specific wavelength into the color of the photochromic layer 61.

[0096] As the ultraviolet-curable resin, for example, an acrylic resin is used. The acrylic resin contains, for example, a polymerization initiator that absorbs UV light having at least one of the wavelengths of 365 nm and 405 nm. As the polymerization initiator, a commercially available polymerization initiator can generally be used.

[0097] The polymerization initiator is excited based on the absorbed light, causes intramolecular cleavage to generate radicals, and reacts with the double bonds of the acrylic resin to initiate polymerization. The base layer 63 also has the effect of improving the adhesion between the nail 401 and the nail 182.

[0098] The photochromic layer 61 is mainly made of an ultraviolet-curable resin and contains a photochromic material. The curable resin is, for example, an acrylic resin, similar to the base layer 63. The acrylic resin has, for example, a polymerization initiator that absorbs UV light having at least one of the wavelengths of 365 nm and 405 nm.

[0099] As the polymerization initiator, a commercially available polymerization initiator can generally be used. As the photochromic material, for example, diarylethene shown in FIG. 10 is used.

[0100] The photochromic layer 61 is mainly made of an ultraviolet-curable resin. The ultraviolet-curable resin has a solubility parameter that is, for example, within a difference of 20% or less, similar to the solubility parameter of the photochromic material, in the state before UV light irradiation.

[0101] As a result, good compatibility is achieved such that the ultraviolet-curable resin and the photochromic material do not separate from each other. The photochromic layer 61 is formed by applying an ultraviolet-curable resin containing a photochromic material onto the base layer 63 and irradiating it with UV light having a wavelength of 365 nm.

[0102] The coating layer 64 is a UV light absorption layer that absorbs UV light in a predetermined wavelength range of ultraviolet rays. The predetermined wavelength range is, for example, as shown in FIG. 4, where the ultraviolet wavelength is from 325 nm to 430 nm.

[0103] The coating layer 64 has, for example, a pigment that absorbs UV light, an organic substance such as a stilbene derivative, etc. The coating layer 64 contains various ultraviolet absorbers. It is possible to appropriately select a material suitable as an ultraviolet absorber (contained in the coating layer 64) suitable for the medium from among various ultraviolet absorbers.

[0104] Since the photochromic material has, for example, an absorption spectrum 76 before UV light irradiation as described in FIG. 4, it develops color when irradiated with UV light that matches the absorption spectrum among the light that has passed through the coating layer 64.

[0105] A part of the UV light irradiated from the lighting device 2 (for example, ultraviolet rays having a wavelength from 325 nm to 430 nm) is absorbed by the coating layer 64. Light having a wavelength shorter than 325 nm passes through the coating layer 64 and is absorbed by the photochromic material of the photochromic layer 61 below it. Therefore, when the photochromic layer 61 is irradiated with light having a wavelength shorter than 325 nm, the photochromic layer 61 develops color. As the photochromic material, for example, diarylethene is used.

[0106] The coating layer 64 shown here contains a photocurable resin, a UV absorber, and a polymerization initiator. The photocurable resin used for the coating layer 64 is, for example, an acrylic resin. The UV absorber is, for example, a stilbene derivative.

[0107] The UV absorber absorbs light with wavelengths ranging from, for example, 325 nm to 430 nm, as shown by line 191 in the graph depicted in FIG. 19. A UV absorber having such characteristics can be obtained by appropriately selecting a commercially available material from film manufacturers or chemical manufacturers as a specific ultraviolet wavelength absorber.

[0108] In addition to absorbing UV light having at least one of the wavelengths 365 nm and 405 nm described above, the polymerization initiator contained in the coating layer 64 has an absorption edge in the visible light region (long wavelength side) having a wavelength of, for example, 430 nm or more, which is outside the light absorption region of the above UV absorber, as shown by line 192 in the graph depicted in FIG. 19. For this reason, the photocurable resin cures with visible light and is one of the photocurable resins generally referred to as a visible light-curable resin. Note that line 193 in the graph shown in FIG. 19 indicates the spectrum of sunlight at the earth's surface. Also, line 194 in the same figure indicates the illumination spectrum for coloring the photochromic layer 61 and has an absorption edge on the short wavelength side among the wavelength bands absorbed by the UV absorber (line 191 in FIG. 19).

[0109] The coating layer 64 cures when irradiated with light that causes cleavage of the polymerization initiator with respect to a mixture of a photocurable resin, a UV absorber, and a polymerization initiator. The absorption edge of the polymerization initiator remains, for example, in the 450 nm and blue regions, and the light absorption is also low compared to other wavelength regions.

[0110] Since the coating layer 64 has the function of absorbing ultraviolet rays, it cures with light having a wavelength ranging from, for example, 430 nm to 450 nm. For example, curing with LED light having a wavelength of 440 to 450 nm is preferable. In order to prevent inhibition of polymerization initiation by oxygen and assist curing, it is preferable to irradiate light and polymerize in a nitrogen atmosphere.

[0111] Here, it is also preferable to irradiate UV light having at least one of the wavelengths 365 nm and 405 nm. Since the coating layer 64 has a UV absorber that absorbs the said wavelength, it may seem contradictory.

[0112] However, it is effective for curing the surface of the coating layer 64 and the portions near the surface. In the vicinity of the surface of the coating layer 64, the polymerization initiator is irradiated with UV light having at least one of the wavelengths of 365 nm and 405 nm that is not completely absorbed by the UV absorber. For this reason, the polymerization initiator cleaves by the UV light having at least one of the wavelengths of 365 nm and 405 nm.

[0113] And, compared with the cleavage of the polymerization initiator by visible light, the efficiency of the cleavage of the polymerization initiator by UV light with higher energy is high. For this reason, for the portion near the surface of the coating layer 64, UV light having at least one of the wavelengths of 365 nm and 405 nm is effective.

[0114] At the surface of the coating layer 64, since oxygen in the air inhibits cleavage, polymerization hardly proceeds. By irradiating with UV light having at least one of the wavelengths of 365 nm and 405 nm, the curing of the surface of the coating layer 64 can be promoted.

[0115] Here, the relationships of the optical properties of the above-described respective materials are organized. It is important for the UV absorber to absorb ultraviolet rays in sunlight, for example, it absorbs light from 325 nm to 430 nm. The photochromic material is colored by irradiation with light in a wavelength range shorter than the absorption wavelength band of the above-described UV absorber, for example, UV light having a wavelength of 325 nm.

[0116] On the other hand, as described above, the absorption edge of the polymerization initiator of the coating layer 64 includes light in a wavelength range longer than the absorption wavelength band of the above-described UV absorber, for example, wavelengths from 440 nm to 450 nm. That is, with respect to the absorption wavelength band of the UV absorber, the photochromic material has an absorption region on the short wavelength side, and the polymerization initiator of the coating layer has an absorption region on the long wavelength side.

[0117] As a result, the formation of the coating layer color conversion layer and the color change of the coating layer color conversion layer are realized. In the figure of FIG. 19, line 193 indicates the spectrum of sunlight on the ground surface, and line 194 indicates the spectrum of the illumination for coloring the photochromic layer 61.

[0118] Subsequently, with reference to FIG. 20, the process of nail formation and color conversion in the second embodiment will be described. FIG. 20 is a flowchart showing the process of nail formation and color conversion in the color conversion system of the second embodiment. <Nail formation process>

[0119] In this case, first, in step S201, an ultraviolet curable resin serving as the base of the base layer 63 is applied to the surface of the nail 182.

[0120] Next, in step S202, by irradiating UV light including at least one of the wavelengths of 365 nm and 405 nm, the ultraviolet curable resin is cured to form the base layer 63.

[0121] Next, in step S203, as the photochromic layer 61, an ultraviolet curable resin added with a photochromic material is applied onto the base layer 63 (ultraviolet curable resin).

[0122] Then, in step S204, by irradiating UV light including at least one of the wavelengths of 365 nm and 405 nm, the ultraviolet curable resin is cured to form the photochromic layer 61.

[0123] At this time, the photochromic material contained in the photochromic layer 61 reacts with the UV light and develops color. Although this color development is secondary, the amount of ultraviolet irradiation (such as the irradiation intensity and irradiation time of the UV light) is controlled so that the color development becomes sufficient color development.

[0124] Next, in step S205, for forming the coating layer, a visible light-curable resin containing an ultraviolet absorber is applied. The UV absorber absorbs light, for example, in the range of 325 nm to 430 nm. The visible light-curable resin contains a polymerization initiator that cleaves with light in a long wavelength region that is not completely absorbed by the ultraviolet absorber, for example, light having a wavelength of 440 to 450 nm.

[0125] Next, in step S206, the visible light-curable resin is cured by irradiating visible light having a wavelength longer than the absorption wavelength of the UV absorber, for example, light in the range of 440 to 450 nm, from an LED light source.

[0126] In step S206, at least one of the wavelengths 365 nm and 405 nm may be irradiated because curing of the surface of the coating layer 64 can be promoted.

[0127] By the processing of steps S201 to S206 as described above, the nail 401 is formed. Note that in step 204, the photochromic layer 61 is colored. However, this coloring is secondary as described above and is colored in an arbitrary color (for example, black etc.) that has nothing to do with the intention.

[0128] <Discoloration process> In step S207, the photochromic material colored in step S204 is faded and reset by irradiating visible light of red (R), green (G), and blue (B) in accordance with the absorption wavelength of the photochromic material whose molecular structure changes by light irradiation.

[0129] Next, in step S208, the photochromic material is colored by irradiating UV light for coloring the photochromic material and short-wavelength UV light that is not absorbed by the coating layer 64, for example, having a wavelength of 325 nm.

[0130] Further, in step S209, by selectively irradiating each of the visible lights of red (R), green (G), and blue (B) with controlled intensity and time according to the absorption wavelength of the colored photochromic material, a predetermined color is realized and the process ends.

[0131] As described above, according to this second embodiment, once the nail 401 is formed on the nail 182 of the human finger 181, thereafter, it can be discolored to a desired color by the lighting device 2. In particular, it becomes possible to change the color of the nail 401 according to clothing or the environment to go out (such as doing sports, being invited to a party, working at a company, etc.).

[0132] <Other examples> The base layer 63 is for improving the adhesion of the entire nail 401 and at the same time serves as a base for avoiding color mixing between the color of the nail 182 and the photochromic layer 61. As shown in FIGS. 1 and 3, when the object to be colored needs to be made transmissive to show the lower dial, such as the windshield glass 42 of the clock 4, the base layer 63 may not be formed.

[0133] In the above example, the nail 401 is formed by applying layers in order to the nail 182, but a material in which the photochromic layer 61 and the coating layer 64 are integrated may also be used. In this case, a visible light curable resin is adopted as the main material, and the visible light curable resin contains an ultraviolet absorber and a photochromic material. In this case, after applying the visible light curable resin to the nail 182, visible light that is not completely absorbed by the ultraviolet absorber is irradiated. Thereby, the visible light curable resin is cured and the nail 401 is formed. However, in this case, the photochromic material will be located including the surface of the nail 401. In such a state, when exposed to sunlight, there is a possibility that UV light reaches the photochromic material without being absorbed by the ultraviolet absorbing material, so the photochromic material may be colored against the intention. For this reason, it is advisable to take measures (such as coating) to block UV light.

[0134] Next, referring to FIG. 21, a third embodiment (example of a general-purpose device) of the color conversion system including the lighting device shown in FIGS. 1 and 3 will be described. FIG. 21 is a diagram showing a third embodiment of the color conversion system including the lighting device shown in FIG. 3. As shown in FIG. 21, in the case of the color conversion system including the lighting device 2 of the third embodiment, the predetermined medium 402 may be any object as long as it is sized to fit into the space inside the lighting device 2. For example, it performs a coloring (color conversion) process on objects such as a pot, a cup, a container, a toy, etc. Note that the portable terminal 1 is the same as that shown in FIGS. 1 to 3 above, and its description will be omitted.

[0135] The lighting device 2 of the third embodiment has a case configured by a left side surface, a right side surface, an upper surface, and a back surface. On each of the upper surface 211, the left side surface 212, and the right side surface 213, a light source unit including a UV light source 55 and an LED light source 56 is arranged. Outside the light source unit, a heat sink 57 and a fan 58 are provided. In addition, a handle 214 protruding in a direction perpendicular to each surface is fixed to the light source unit. Further, on each surface, a guide mechanism 215 that engages with the handle 214 and enables the light source unit to slide is provided. In the case of this lighting device 2, the user can move the light source unit up and down (in the direction of arrow Y) and left and right (in the direction of arrow X) with each handle 214 to adjust the irradiation distance between the light source and the predetermined medium 402.

[0136] In the case of this lighting device 2 of the third embodiment, functional elements other than the light source are arranged in an external control device (not shown). The functional elements are the communication unit 51, the light source driving unit 52, the power supply unit 53, etc. shown in FIG. 3. Therefore, the lighting device 2 and the control device are connected by a communication line and a power cord. Note that the control information from the portable terminal 1 is transmitted to the lighting device 2 via the control device. The operation is the same as that of the first embodiment above.

[0137] According to the color conversion system including the lighting device 2 of this third embodiment, it can correspond to a coloring target (predetermined medium 402) of a certain size, and can be made high-output by heat dissipation measures such as the heat sink 57 and the fan 58. It is possible to color objects larger than the clock 4, the nail 401, etc., and it can be used for general-purpose applications.

[0138] Next, a fourth embodiment (example where the coloring target is glasses) of the color conversion system including the lighting device shown in FIGS. 1 and 3 will be described with reference to FIG. 22. FIG. 22 is a diagram showing a fourth embodiment of the color conversion system including the lighting device shown in FIG. 1. As shown in FIG. 22, in the case of the lighting device 2 of the fourth embodiment, the predetermined medium is glasses 411, and as the color conversion layer formed on the glasses 411, the two-layer color conversion layer 60 shown in FIG. 3 is applied. The lighting device 2 is composed of a case 221 and a lid 222 that can be removed from the case 221. The inside of the case 221 is partitioned into a plurality of compartments by partition plates, and storage spaces 223 for each part 412 of the glasses 411 are provided. The UV light source 55 and the LED light source 56 shown in FIG. 3 are arranged on the lid 222. In addition to the entire glasses 411, the color designation screen of the mobile terminal 1 can also specify colors for each part 412. In addition, the functional configuration of the mobile terminal 1 is the same as that of the first embodiment (see FIG. 3), and the description thereof will be omitted.

[0139] According to the color conversion system including the lighting device 2 of the fourth embodiment, it is possible to perform coloring (color conversion) for each part in a state where the parts are separated, as well as for the glasses 411 alone.

[0140] Next, a fifth embodiment (example where the coloring target is jewelry) of the color conversion system including the lighting device shown in FIGS. 1 and 3 will be described with reference to FIG. 23. FIG. 23 is a diagram showing a fifth embodiment of the color conversion system including the lighting device shown in FIG. 1. As shown in Fig. 23, in the case of the fifth embodiment, the predetermined medium is the jewelry 421, and the lighting device 2 is composed of a case 231 having an opening at the upper part and a lid 232 capable of opening and closing the opening of the case 231. The case 231 is provided with a seat portion 233 inside so as to support the ring portion of the jewelry 421.

Set colors that can only be bought at a specific location in cooperation with location information. · When new colors come out, they can be used digitally at any time. Users can download new colors at any time. · It is possible to buy one color at a time. It is also possible to buy all 24 colors together. It is also possible to select multiple colors and make a purchase. · Allow corporate monopolization of color information as a strategy (contract).

[0166] <Billing Method> · It is possible to provide services under a subscription contract (monthly fixed amount) in a set with the device. · It may be possible to charge a fee when changing the color. · Further sell in-app purchases + additional functions (e.g., gradients) as options. · It is also preferable to halve the app's revenue (profit). Billing section, color setting section, color reception, color fee setting section (as a margin when developed as a collaboration with other companies rather than in-house products). · Since the living environment varies for each user, if the color disappears within the warranty period, product warranty is provided within the warranty time. For example, in the case of nails 182 (see Figure 18), it is guaranteed for about 12 hours, and for hair, etc., it is guaranteed for about one week.

[0167] <Usage> · Usage includes painting of moving vehicles such as cars and airplanes, clothes, bags, jewelry, eyeglass frames, lenses, household appliances. All products containing dyes such as nails, foundation, eyeliner, hair color, etc. Products made with this technology can have their color changed at any time. · As a tester function for product purchase, it can be used to check the color by oneself and as a product to attract customers to visit the store to buy the actual product. · Along with the distribution of limited colors for enterprises, a two-dimensional code is distributed, and colors are added to the digital palette in the form of reading this two-dimensional code. · Every time the app is used, secondary information (gender, location, time, product, color, irradiation location) is acquired by the service provider's server, etc. The server provides information to the app on the user's mobile terminal in the form of trends based on the acquired data. The information is, for example, such and such a person purchased this color, used it, etc.

[0168] <Features> · The color conversion system is characterized in that it replaces the information of the specified color with optical information (light source control information). It is defined by combinations of the irradiation time, output, irradiation range, ratio, etc. of each of R, G, and B. In this regard, it can be differentiated from inkjet printers, etc. ·The color conversion system can change the structure and irradiation conditions of the lighting device 2 (irradiation device) according to the guarantee time for coloring.
