[0013] Hereinafter, several embodiments of the nail dyeing device will be specifically described with reference to FIGS.

[0014] [1. First embodiment] [1-1.Configuration] The nail photo-dyeing device 1 of this embodiment is shown in Figures 1 and 2 and includes a mitten-shaped main body 2 and a control unit C. Although it is portable, when in use the main body 2 is placed on a flat surface such as a desk or table.

[0015] In the photo-dyeing process, after applying photo-dyeing agent to the nails, the hand is inserted palm-down into the opening 3 of the main body 2. The main body 2 is equipped with a strip light that provides uniform illumination.

[0016] The main body 2 is made of a hard resin such as polycarbonate. A space A for inserting a hand is provided between the ceiling 21 and the bottom 22 of the main body 2. A hand can be inserted into the space A through an opening 3 in the main body 2. The direction in which the hand is inserted in the main body 2 is defined as the depth.

[0017] Space A is designed so that a hand can be inserted without the stained nails touching the ceiling 21. Space A has a depth greater than the length from the tip of the thumb nail to the tip of the middle finger nail.

[0018] At the bottom of Space A is a mounting base 4 made of polyurethane and EVA resin. The mounting base 4 has a groove that resembles the shape of a palm, and is designed so that by placing a hand on it, the light from the LED strip light 5 will shine evenly on the nails.

[0019] A tape light 5 is placed on the space A side of the ceiling 21. The tape light 5 is placed on one side of the inside of the ceiling 21. The wiring 51 of the LED tape light 5 is passed through the inside of the ceiling 21 and is not exposed on the surface of the ceiling 21.

[0020] The LED strip light 5 used includes, for example, RGB LEDs 52 of three colors, red, green, and blue. The RGB LEDs 52 arranged are preferably three colors, but may be two colors. These LEDs 52 are used as the strip light 5 arranged on a flexible tape.

[0021] Strip Light 5 is a device that emits light to color the photo-dye applied to nails. It uses three colored LEDs that flash rapidly and mix the colors to work as a single light source. Each LED emits light of a specific color wavelength, which allows for a variety of color effects. Strip Light 5 is thin, flexible, and self-adhesive, making it easy to install in a variety of locations.

[0022] The strip light 5 is connected to an RGB color control unit C, which controls the light emission and brightness of each color LED. As shown in Figure 3, the control unit C includes a color selection unit C1, a brightness adjustment unit C2, and an irradiation time timer C3.

[0023] The color selection unit C1 controls the LED light emission of a specified color. For example, if "purple" is selected, the red and blue LEDs are mixed to emit purple light. The brightness can be adjusted using the brightness adjustment button. In other words, the color tape 5 obtains the desired color light by combining the three basic colors of red, green, and blue, which is the principle of "additive color mixing," to create different colors. When a specified color is selected, the color selection unit C1 determines the ratio of the three basic colors of red, green, and blue required to emit that color.

[0024] The brightness adjustment unit C2 adjusts the brightness while maintaining the color set by the color selection unit C1 by increasing or decreasing the proportions of the three basic colors of red, green, and blue required to emit that color, i.e., each component of the RGB value (R, G, B), at the same ratio. This brightness adjustment increases or decreases the brightness of the color emitted from the color tape 5, thereby changing the coloring speed and color development state of the photo-dye applied to the nails.

[0025] It should be noted that the brightness adjustment unit C2 is not necessarily required in the present invention; it is sufficient that each component (R, G, B) of the RGB value is determined in the color selection unit C1, and it is also possible to directly cause the LED 52 to emit light based on the brightness value of each component (R, G, B) of the RGB value determined by the color selection unit C1.

[0026] The illumination time timer C3 adjusts the illumination time of the LED 52 determined by the color selection unit C1 and the brightness adjustment unit C2.

[0027] An input terminal 10 for causing the user to color the photo-dyeing agent applied to the nail in a desired color is connected to the RGB color control unit C. As shown in Fig. 3, this input terminal 10 includes a display unit 11 that displays a plurality of color samples a to n to the user, and an input unit 12 that receives a command from the user to select one of the color samples a to n.

[0028] The input terminal 10 can be an integrated display unit 11 and input unit 12, with a touch panel type liquid crystal display provided in the same housing 15 as the control unit C. In addition, a plurality of color samples can be displayed as an application on the display of a computer such as a smartphone, tablet, or personal computer, and the desired color sample can be selected using a mouse or touch panel by displaying buttons for selecting the desired color on the display, or by using an input unit such as a keyboard or other physical device.

[0029] Alternatively, the display unit 12 may be a sheet on which a number of color samples are printed, attached to the housing of the control unit C, and an input unit 12 such as a switch, button, or dial for selecting a desired color sample may be provided in part of the housing.

[0030] The input terminal 10 or the control unit C is provided with a database 13 that associates each of the color samples a to n displayed on the display unit 11 with the LED brightness and irradiation time required to obtain nail colors corresponding to the displayed color samples a to n. The input terminal 10 or the control unit C is also provided with a search unit 14 that searches the database for the brightness and irradiation time of the LED 52 that correspond to the color sample selected by the input unit 12 and outputs the search results to the control unit C.

[0031] Based on the search results from the search unit 14, the control unit C adjusts the brightness ratio of the RGB LEDs that make up the LED 52 and the overall brightness of the LED 52 using the color selection unit C1 and brightness adjustment unit C2, and also adjusts the irradiation time of the LED 52 using the irradiation time timer C3.

[0032] [1-2. Effect] The operation of the nail dyeing device of this embodiment will be described below along with the operating procedure of the user.

[0033] When applying gel nails or nail art to the nails, the user applies a known photo-dyeing agent to the nails of one hand. Next, by irradiating the nails with light using the strip light 5, the photo-dyeing agent reacts and the nails change to the desired color.

[0034] Before the treatment, the user displays a plurality of color samples a to n on the display unit 11 of the input terminal 10 and selects the color of the nails they wish to dye using the input unit 12. When the user inputs a selection command indicating which color to dye the nails, the search unit 14 searches the database 13 to obtain the brightness and irradiation time of the LEDs corresponding to the color sample in the selection command, and outputs them to the control unit C.

[0035] Based on the LED brightness and irradiation time obtained from the database 13, the control unit C adjusts the brightness ratio of the RGB LEDs that make up the LED 52 and the overall brightness of the LED 52 using the color selection unit C1 and brightness adjustment unit C2, and also adjusts the irradiation time of the LED 52 using the irradiation time timer C3. In other words, as the irradiation time becomes longer, the color development progresses and the photo-dye develops a darker hue, so even if the ratio of each component of the RGB value (R, G, B) is the same, the resulting nail color changes, allowing for a wider variety of colors to be developed.

[0036] For example, when using a specific photo-dyeing agent, such as "Easy Color Gel" manufactured by E-Wellness Puinpuru Cosmetics Co., Ltd., nails can be dyed as shown in Table 1 below depending on the color of the tape light 5.

[0037] [Table 1]

[0038] If the LED is turned on by a start switch separate from the selection of the color sample by the input unit 12, the user may select the color sample before or after applying the photo-dyeing agent to the nails. Also, by configuring the input unit 12 to allow selection of color samples a to n for each individual finger, it is possible to dye all nails with the same color or to dye each finger with a different color.

[0039] After selecting one of the desired color samples a to n from the input unit 12 as described above, the user places the applied hand with the palm facing down in space A of the device. Then, when the user turns on the switch of the nail dyeing device with the unapplied hand, the device starts up and light from the strip light 5 is irradiated onto the nail.

[0040] For example, to dye nails brown, the light emitted from the light strip 5 is set to red (R), green (G), and blue (B) at the same brightness. As a result, white light is emitted from the light-emitting part of the light strip 5, and the nails are dyed brown as shown in Table 1.

[0041] When the user selects another color from the color samples a to n using the input unit 12, the search unit 14 searches the database 13, and the required brightness ratio and irradiation time are output to the control unit C. Based on these conditions, the control unit C operates the color selection unit C1, brightness adjustment unit C2, and irradiation time timer C3, and adjusts the tape light 5 to the desired color, for example, as shown in Table 1.

[0042] After dyeing the nails to the desired color, remove your hand from Space A and apply top coat gel to the nails. The top coat gel used contains ingredients that stop the dyeing of the photo-dye. Therefore, applying the top coat gel to the nails stops the dyeing of the photo-dye caused by light.

[0043] [1-3.Effects] (1) In the nail dyeing device of the embodiment, when a user simply selects a color sample displayed on the display unit 11, the conditions for coloring the nail to a color similar to the color sample are searched from the database 13 and output to the control unit C. As a result, the user can dye the nail to the desired color without having to adjust the brightness or fermentation time of the three RGB LEDs by themselves.

[0044] (2) The control unit C has a color selection unit C1, a brightness adjustment unit C2, and an irradiation time timer C3. By combining and saving these three parameters in a database, a wide variety of colors can be produced, making it possible to present a variety of color samples to the user. In addition, by using the brightness adjustment unit C2 and the irradiation time timer C3, it is also possible to adjust the color production time and color density, which is very convenient for the user.

[0045] (3) The nail light dyeing device 1 has an opening 3 into which the entire fingertips of multiple fingers are inserted, and a main body 2 that covers the entire nails of multiple fingers. This allows dyeing of the nails of multiple fingers, shortening the treatment time. Furthermore, since the LEDs are irradiated simultaneously, there is less variation in the finished result. Furthermore, by making the depth of the main body 2 the same as the length from the nail of the thumb to the tip of the nail of the index finger, the size of the main body 2 can be reduced.

[0046] [2. Second Embodiment] [2-1.Configuration] The nail photo-dyeing device 1 of this embodiment is shown in Figures 4 and 5, and is a modification of the main body 2 of the first embodiment. The main body 2 has two openings 3, one at the front and one at the back, and is semicircular or arch-shaped. The depth of the main body 2 is more than twice the length from the tip of the thumb nail to the tip of the middle finger nail. The configurations of the control unit C and input terminal are the same as those of the first embodiment.

[0047] [2-2. Actions and Effects] In addition to the advantages (1) and (2) of the first embodiment, this embodiment has the advantage that the semicircular or arched body allows the hand to be placed underneath, enabling uniform light irradiation from above. This shape is suitable for effectively dispersing light across the entire finger. Furthermore, the openings at the fingertips allow heat generated by the LEDs to be smoothly released to the outside, preventing the fingertips from becoming too hot. Treatment can be performed by inserting the hand into either of the two openings 3 at the front and rear of the main body 2. Furthermore, the increased depth allows treatment on both hands simultaneously.

[0048] 3. Third Embodiment [3-1.Configuration] The nail photo-dyeing device 1 of this embodiment is shown in Fig. 6, and is a modification of the first embodiment in that the main body 2 and opening 3 are sized differently. The main body 2 is large enough to accommodate one finger. The configurations of the control unit C and input terminal are the same as those of the first embodiment.

[0049] [3-2. Actions and Effects] In addition to the advantages (1) and (2) of the first embodiment, this embodiment can be conveniently used when treating a single finger. The size of the main body 2 can be reduced, allowing you to enjoy dyeing your nails more easily.

[0050] [4. Fourth Embodiment] [4-1.Configuration] The nail photo-dyeing device 1 of this embodiment is shown in FIG. 7, and is provided with a light-shielding cover 6 that blocks light from entering space A at the opening 3 of the main body 2 of the first embodiment. The light-shielding cover 6 prevents light from entering through the opening 3. The light-shielding cover 6 has an opening 61 for inserting a hand, and the size of the opening 61 is adjustable with a drawstring 62. Furthermore, a size adjustment function can be added around the opening 61. The configurations of the control unit C and input terminal are the same as those of the first embodiment.

[0051] [4-2. Actions and Effects] In this embodiment, in addition to the effects (1) and (2) of the first embodiment, during treatment, the user places his / her hand from the entrance 61 into the space A, and then slightly opens the entrance 61 of the light-shielding cover 6 with the other hand, thereby blocking light from entering the main body 2. This has the effect of enabling control of the degree of dyeing without being affected by external light, even when using a photo-staining agent that is sensitive to light. It also prevents the LED light from irradiating the user's eyes.

[0052] 5. Other Embodiments Although the embodiments of the present invention have been described above, various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as set forth in the claims. The following is an example.

[0053] (1) The control unit C only has a color selection unit C1 that adjusts the brightness of each RGB LED to emit a desired color, and the brightness of the entire LEDs is set to a fixed value determined by the color selection unit C1, and the irradiation time is also set to a fixed value, so that it is possible to configure the control unit C without providing the brightness adjustment unit C2 or the irradiation time timer C3. In other words, in the present invention, controlling the brightness and irradiation time also includes selecting them as fixed values.

[0054] (2) By using a two-tier structure with an LED placed at the top and a reflector or diffuser at the bottom, the reflected light can be used to effectively illuminate the nails.

[0055] (3) A single-color LED can be used, and in that case, the degree of dyeing of the nail can be adjusted by adjusting the irradiation time.

[0056] (4) If necessary, additional cooling functions (e.g., cooling fans) can be incorporated. This allows the device temperature to be kept within an appropriate range even when high light output is required. do. [Explanation of symbols]
