  The present invention relates to a fruit color development device capable of irradiating light of a wavelength region that efficiently promotes color development of a fruit skin (surface) as a three-dimensional irradiation target.

In general, it is known that coloring of the fruit peel of a fruit in a plant body occurs when a coloring substance (for example, polyphenols containing anthocyanins) is produced in the peel. And well-colored fruits are traded at high prices because they look good.
Moreover, according to recent research results, depending on the type of plant body, it is known that irradiation with light having a specific wavelength region is effective for promoting the production of colored substances in the fruit peel.

For this reason, producers devised to increase the amount of sunlight on the fruit skin (surface) by removing the leaves around the fruit during the harvest period, or laying a sheet that reflects light rays under the fruit tree. Yes.

On the other hand, for example, at the time when the skin of apples and the like is colored, a light-impermeable seal shaped like a letter or a figure is temporarily attached to the surface of the fruit to prevent sunlight on the part. Fruits in which letters and figures are drawn on the surface of fruits are distributed as high value-added products using the contrast with the colored skin produced by suppressing the production of colored substances and the surrounding colored substances.
When such high value-added fruits are produced in the open ground or in a greenhouse, in addition to the risk of the fruits becoming defective due to damage by insects, birds and beasts, they are not transparent due to the effects of lack of sunlight. If the color of the peeled part is poor, there is a risk that it cannot be shipped as a product. In the latter case in particular, the fruit has characters and figures drawn on the surface of the fruit, so it must be handled as a scratched item or a defective product. It could not be distributed as a product. For this reason, when producing high-value-added fruits, the risk of defective products at the time of production is particularly high, and it was difficult for the producers to produce a large amount of high-value-added products as described above. .
For this reason, there has been a demand for an apparatus that can efficiently irradiate light in a wavelength region that promotes color development of the pericarp on the entire circumference of the pericarp (surface) of the fruit to be irradiated having a three-dimensional shape. At present, no prior art having the same object and configuration as the present invention has been found, but related prior art is known as shown below.

That is, according to the fruit color development promoting apparatus 1A according to the first embodiment, the fruit 6a to be irradiated is accommodated in the container body 2, and the reflection portion 4 is formed on the inner surface of the container body 2, By providing the LED light source 3 on the inner surface of the container body 2, the color development of the fruit 6a can be promoted efficiently with a small amount of light.
In particular, by using the LED light source 3 as a light source that emits light in a wavelength region that promotes color development of the skin, the amount of heat generated during light emission can be reduced. As a result, even when the light source is caused to emit light in a closed space (including the concept of a substantially closed space), the temperature in the container body 2 does not increase significantly. It can be surely prevented.
By using the fruit color development promoting device 1A according to Example 1 as described above, it is possible to efficiently promote the color development of the fruit skin of the fruit 6a indoors where there is no fear of insect damage or bird damage. Further, in this case, the entire circumference of the fruit skin of the fruit 6a can be efficiently irradiated with light in a wavelength region that promotes the color development of the fruit skin, so there is no need to change the direction of the fruit 6a during the color development promoting process. Therefore, the high value-added fruit 6a can be produced safely and efficiently indoors.

Furthermore, before performing the process using the fruit color facilitating apparatus 1A according to Example 1, a translucent seal (not shown) in the shape of characters and figures is pasted on the surface of the fruit 6a in advance. Thus, the color development of the skin of the portion where the seal is affixed is suppressed, while the color development of the skin is promoted in the other portions, so that characters and figures can be drawn on the surface of the fruit 6a by these contrasts.
As a result, it is possible to efficiently produce high-value-added fruit 6a with good color development and vividly drawn characters and figures on the surface of the skin.

In general, when producing high-value-added fruit with such characters and figures drawn outdoors or outdoors in a greenhouse, etc., using natural sunlight, it is not possible to give sunlight all around the fruit at the same time. Therefore, it was necessary to change the direction of the fruit during processing, which was troublesome. In addition, since there are fruits outdoors, there is a risk of insect damage and bird damage, and it was necessary to prepare a spare in order production.
Fortunately, even if the insects and birds are free from damage, if only half of the fruit can be colored well due to bad weather, the fruit can be distributed as a high value-added product. Furthermore, since figures and characters are drawn on the fruit, it cannot be distributed as a normal product, so it must be finally treated as a defective product or a scratched product.
In other words, when producing high-value-added fruits with characters and figures drawn outdoors, there was a high risk that the fruits would become defective due to the circumstances described above. By using 1A, it is possible to significantly reduce the risk of defective products as described above, and to efficiently produce high value-added fruits 6a.

  In addition, in FIG. 1, although the shape of the container body 2 is made into a hollow spherical shape, the case where this spherical container body 2 is comprised by the upper part 2a and the lower part 2b which can be opened and closed is mentioned as an example. Is not necessarily limited to those shown in the drawings, and is a container body 2 that can accommodate the entire fruit 6a to be irradiated, and is configured to allow the fruit 6a to be taken in and out from the outside. Any form can be used. For example, if the shape of the fruit is long and thin, the container body 2 may be an ellipsoid. In FIG. 1, the container body 2 is divided into two parts and can be opened and closed. May be divided into two or more and a part or all of them may be configured to be openable and closable. Alternatively, instead of dividing and opening the container body 2, a door for putting the fruit 6 a in and out of the container body 2 may be provided, and the door 6 may be opened and closed to allow the fruit 6 a to be taken in and out.

Moreover, in order to use the light emitted from the LED light source 3 without waste in the fruit color development promoting device 1A according to the first embodiment, the container body 2 is desirably a closed space, but the container body 2 is not necessarily a closed space. There is no need.
That is, when the container body 2 is not a completely closed space, the container body 2 has a gap, so that a part of the light emitted from the LED light source 3 leaks from this part, and the light is used to promote color development of the skin. Although it has a demerit that it cannot be used effectively, it does not mean that the function of the fruit color facilitating device 1A according to Example 1 is substantially impaired.
Therefore, the concept of the container body 2 of the fruit color facilitating apparatus according to the present invention is not limited to the container body 2 that forms a completely closed space, but has a gap in a part of the container body 2 or one of the container bodies 2. It is a concept that includes a permanent opening for taking in and out the fruit 6a and taking in light from the outside (see Example 5 described later).

Moreover, although the case where the mounting part 5a for mounting the fruit 6a in the container body 2 is installed in FIG. 1 is described as an example, the mounting part 5a is not necessarily provided. As a method of installing the fruit 6a in the container body 2, in addition to the above-described method, for example, a means of suspending and holding the fruit 6a with a string in the container body 2 may be employed.
Moreover, you may use what was comprised with translucent materials, such as glass, as the mounting part 5a, for example. In this case, the light emitted from the LED light source 3 can also be irradiated to the mounting surface of the fruit 6a.
In addition, the matter regarding the accommodation method and installation method of the fruit in the container body 2 is applicable also to the other Example of this invention.
Further, the reflecting portion 4 formed on the inner surface of the container body 2 is configured such that, for example, the container body 2 is made of metal and the surface thereof is mirror-like to improve the reflectivity of the light emitted from the LED light source 3. Alternatively, the reflective portion 4 may be formed by applying a coating that efficiently reflects the light emitted from the LED light source 3 to the inner side surface of the container body 2 to form a coating film.
In addition, since the container body 2 is provided in order to prevent the dissipation of light emitted from the LED light source 3 and use it effectively, the container body 2 has a structure that hardly transmits the light emitted from the LED light source 3. Alternatively, the container body 2 needs to be made of a material that is difficult to transmit light emitted from the LED light source 3. More specifically, for example, a coating layer such as a paint that hardly transmits light emitted from the LED light source 3 may be formed in the lower layer of the reflection portion 4 on the inner side surface of the container body 2. Moreover, what is necessary is just to make the container body 2 metal, when the light emitted from the LED light source 3 does not permeate | transmit a metal.
In the latter case, if the light emitted from the LED light source 3 is efficiently reflected on the surface of the metal container body 2, the inner side surface of the metal container body can also be used as the reflecting portion 4. . On the other hand, when the inner surface of the container body 2 prevents the light emitted from the LED light source 3 from being transmitted but does not efficiently reflect the light emitted from the LED light source 3, the reflecting portion 4 made of a paint or a coating is separately provided in the container. It is necessary to form it on the inner surface of the body 2.

Moreover, in FIG. 1, although the case where an apple is used as an example of the fruit 6a is described as an example, the fruit 6a is not limited to apples but also has light in a specific wavelength region (light in a specific wavelength region is Any fruit can be used as long as the color development of the skin can be promoted by irradiation with a plurality of types (including cases where a plurality of types are necessary). In this case, it is necessary to use the LED light source 3 that emits light that contributes to the promotion of color development of the fruit accommodated in the container body 2.
Specific examples of the fruit 6a other than apples that can be used in the fruit color development device according to the present invention include, for example, grapes, strawberries, peas, eggplants, figs, ume, mango, and peaches. In addition, the wavelength range of the light by which the promotion effect of color development is recognized in each of the nine types of fruits 6a described above is shown in Table 1 below for reference.

As shown in the table above, although the wavelength of light considered to be effective in promoting the color development of the pericarp varies depending on the subject to be irradiated, overall irradiation with light having a wavelength in the ultraviolet to visible light region Can be said to be effective. This is reasonable considering the fact that plants grow under sunlight.
Therefore, when the fruit 6a accommodated in the container body 2 of the fruit color facilitating apparatus 1A according to Example 1 is a specific type, the LED light source 3 emits light in a wavelength region that promotes the color development of the fruit 6a ( The light may need to be emitted from a plurality of types), and the reflecting portion 4 formed on the inner surface of the container body 2 may emit light from the LED light source 3 (a plurality of wavelengths of the light may be used). Must be able to be reflected efficiently. In addition, although it is desirable for the reflection part 4 to have the high reflectance of the light emitted from the LED light source 3, compared with the case where the container body 2 is not provided, by providing the container body 2 and the reflection part 4, even a little is irradiated. If the irradiation efficiency of the light to the object can be improved, the reflectance of the reflecting portion 4 is not particularly problematic.
In addition, when the fruit color facilitating device 1A according to Example 1 is considered without specifying the fruit 6a accommodated in the container body 2, any fruit is irradiated with light having a wavelength in the visible light region from ultraviolet light. Since it can be said that color development is promoted, it can be said that the reflection part 4 formed on the inner surface of the container body 2 only needs to have reflectivity of light having a wavelength in the range from ultraviolet light to visible light.
That is, as the reflection part 4 in the fruit color facilitating apparatus 1A according to the first embodiment, for example, one made of a silver plating film or vapor-deposited aluminum film, one made by polishing a metal surface such as stainless steel, and having a mirror shape, titanium oxide Reflecting or diffusing light such as white pigments such as barium sulfate, and coating films containing conventionally known white materials such as magnesium carbonate, calcium carbonate, and calcium sulfate, white acrylic and gypsum What uses the material which has the effect to do can be employ | adopted.
In addition, “UV-A” described in this specification and Table 1 is light in a wavelength region of 320 to 380 nm, and “UV-B” is light in a wavelength region of 280 to 320 nm. “Light in the light region” is light in the wavelength region of 380 to 780 nm.

Moreover, when the fruit 6a accommodated in the container body 2 of the fruit coloring promotion apparatus 1A according to Example 1 is not specified for the same reason, the light emitted from the LED light source 3 is close to natural sunlight. Good. That is, the LED light source 3 may emit white light including ultraviolet light and visible light.
Moreover, since it is necessary to irradiate the light emitted from LED light source 3 at once to the perimeter of fruit 6a which is an irradiation object, LED light source 3 is arrange | positioned in the state disperse | distributed to the inner surface of the container body 2. FIG. However, since the inner surface of the container body 2 includes the reflecting portion 4, the light emitted from the LED light source 3 can be efficiently diffused into the container body 2. You may arrange | position at least 1 place or more of a side surface at the spot form.

  Further, as a modification of the fruit color development promoting device 1A according to the first embodiment, although not particularly illustrated, the entire inner surface of the container body 2 may be a planar light source using an LED light source. In this case, it is not necessary to form the reflecting portion 4 on the inner side surface of the container body 2. Also in this case, the same effect as the fruit color development promoting device 1A according to Example 1 described above can be exhibited.

A fruit color promoting device according to Example 2 of the present invention will be described in detail with reference to FIGS.
As shown in FIG. 1, the fruit color promoting device 1 </ b> A according to Example 1 described above is arranged in a state where the shape of the container body 2 is, for example, a spherical shape, and the LED light source 3 is dispersed on the inner surface of the container body 2. It was to be established. Such a fruit color development promoting device 1A according to Example 1 reduces irradiation unevenness when irradiating the target light with the entire circumference of the surface of the fruit 6a accommodated in the container body 2. On the other hand, there is a problem that it takes time to manufacture the container body 2 provided with the LED light source 3 on the other hand, and as a result, it is difficult to provide the fruit color development promoting device 1A at low cost. In view of such circumstances, a fruit color facilitating apparatus according to Example 2 of the present invention was invented.

FIG. 2 is a conceptual diagram of a fruit color facilitating device according to Example 2 of the present invention, and FIG. 3 is a conceptual diagram illustrating a disassembled state of the fruit color facilitating device according to Example 2 of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
As shown in FIGS. 2 and 3, in the fruit color facilitating device 1B according to the second embodiment, the container body 2 for housing the fruit 6a to be irradiated is provided in the cylindrical body portion 7 and the upper opening thereof. The upper surface portion 8 and the lower surface portion 9 provided in the lower opening of the cylindrical body portion 7 are configured, and the LED light source 3 is provided on the upper surface portion 8 and the lower surface portion 9. Needless to say, the LED light source 3 forms the inner surface of the container body 2 when the upper surface portion 8 and the lower surface portion 9 are attached to the upper and lower openings of the cylindrical body portion 7 to form the container body 2. It is provided on the surface.
Furthermore, on the inner surface of the container body 2, that is, on the inner surface of the cylindrical body portion 7 and the surface on the side where the LED light source 3 is disposed in the upper surface portion 8 and the lower surface portion 9, the fruit according to the first embodiment. The reflection part 4 is formed as in the case of the color development promoting device 1A.
Moreover, although not specifically illustrated, the fruit color development promoting device 1B according to the second embodiment includes a power distribution facility for supplying power to each LED light source 3 and a power capture facility for capturing power into the power distribution facility from the outside. ing.

  In the fruit color development promoting apparatus 1B according to the second embodiment, as shown in FIG. 3, a placing part 5b may be provided on the lower surface part 9, and the fruit 6a to be irradiated may be placed thereon. The fruit 6a may be placed directly on the lower surface portion 9 without providing the placement portion 5b. Moreover, the light emitted from the LED light source 3 can be irradiated also to the bottom of the fruit 6a by comprising especially the mounting part 5b with transparent glass or a synthetic resin, for example.

According to the fruit color development promoting apparatus 1B according to the second embodiment as described above, the skin is efficiently peeled around the entire circumference of the fruit 6a to be irradiated, like the fruit color development promotion apparatus 1A according to the first embodiment described above. It is possible to irradiate light in a wavelength region that promotes color development. Therefore, the fruit color development promoting device 1B according to the second embodiment has the same effect as the fruit color development promoting device 1A according to the first embodiment.
In addition to this effect, the fruit color facilitating device 1B according to the second embodiment is configured such that the container body 2 includes a cylindrical body 7, and a plurality of parts including an upper surface portion 8 and a lower surface portion 9, and the upper surface portion 8, The LED light source 3 is provided only on the lower surface portion 9, and the mounting position of the LED light source 3 is concentrated at a specific location. Thereby, manufacture of the fruit coloring promotion apparatus 1B which concerns on Example 2 can be made easy.
As a result, the fruit color facilitating device 1B according to Example 2 can be provided at a lower cost.
2 and 3, the case where a hexagonal cylinder is used as the cylindrical body portion 7 is described as an example. However, the cylindrical body portion 7 may be a cylinder or a polygonal cylinder other than the hexagonal cylinder.

FIG. 4 is a perspective view showing a state in which a plurality of fruit color facilitating devices according to Example 2 of the present invention are connected in the horizontal direction. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted.
When the cylindrical body portion 7 in the fruit color development promoting device 1B according to the second embodiment is a hexagonal cylinder, as shown in FIG. 4, the fruit color development promoting device 1B according to the second embodiment is formed in a honeycomb shape in the horizontal direction. Since it can arrange | position without gap, it can improve the utilization efficiency of the space at the time of installing two or more fruit coloring promotion apparatuses 1B indoors. Moreover, also when the cylinder part 7 of the fruit coloring promotion apparatus 1B which concerns on Example 2 is made into the square cylinder, the utilization efficiency of the space which arrange | positions the fruit coloring promotion apparatus 1B can be improved similarly.
Moreover, while fixing adjacent fruit coloring promotion apparatus 1B with the coupling tool which is not shown in figure, it is comprised so that electric power can be transmitted to the adjacent fruit coloring promotion apparatus 1B via this connection part, and many fruit coloring promotion apparatuses When 1B is installed, it is possible to smoothly supply power to the plurality of fruit color facilitating devices 1B.

2 and 3 again, in the fruit color facilitating device 1B according to the second embodiment, the lower surface portion 9 constituting one fruit color facilitating device 1B and another fruit color facilitating device 1B are constructed. By forming the light-emitting mounting part 12 integrally connected to the upper surface part 8 through the connecting part 11, and providing at least one connecting part 10 on the side surface of the light-emitting mounting part 12, the embodiment 2 can be easily stacked in the vertical direction.
FIG. 5 is a perspective view showing a state in which a plurality of fruit color facilitating devices according to Example 2 of the present invention are connected in the vertical direction. The same parts as those described in FIGS. 1 to 4 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 5, in the fruit color development promoting device 1 </ b> B according to the second embodiment, the upper surface portion 8 and the lower surface portion 9 are integrated with each other via the connecting portion 11 to form the light emitting placement portion 12. The assembly of the fruit color development promoting device 1B can be easily formed by a simple operation of alternately stacking the placing portions 12 and the cylindrical body portions 7. In this case, the space utilization efficiency in the vertical direction can be increased when a plurality of fruit color facilitating devices 1B according to Example 2 are accommodated indoors.

In addition, as shown in FIGS. 2, 3, and 5, when the upper surface portion 8 and the lower surface portion 9 including the LED light source 3 are integrated via the connection portion 11, power is supplied to the LED light source 3 inside the connection portion 11. Since the power distribution equipment for supply can be stored in a compact manner, also in this respect, the space utilization efficiency when a large number of fruit color facilitating devices 1B according to Example 2 are installed indoors can be increased.
Although not particularly illustrated, a power transmission structure for transmitting electric power is provided on the thick portion or the surface of the cylindrical body portion 7, and this power transmission structure is promoted for fruit coloring of other layers via the connection portion 10. By electrically connecting to the power transmission structure of the device 1B, even when a large number of fruit color facilitating devices 1B are installed, power can be smoothly supplied without a complicated wiring structure.

2 to 5 described above, a description has been given of the fruit color facilitating device 1B of a type that accommodates one fruit 6a in one container body 2. However, one giant fruit color facilitating device 1B is manufactured. In addition, a partition (not shown) whose surface is entirely made up of the reflecting portion 4 may be provided to form a plurality of compartments, and the fruit 6a may be accommodated one by one in each compartment. In this case, the manufacturing cost of the fruit color development promoting device 1B can be reduced while exhibiting the same effect as the case of using the aggregate of the fruit color development promotion apparatus 1B as shown in FIG. In particular, when the space for installing the fruit color development promoting device 1B is large, the equipment for introducing the fruit color development promotion device 1B by dividing and using the inside of the container body 2 of the fruit color development promotion device 1B by a partition. Investment can be saved.
Moreover, in the case of the fruit coloring promotion apparatus 1B of the type which provides the above-mentioned partition, the fruit coloring promotion apparatus 1B is used also with respect to several types of irradiated objects from which a magnitude | size changes by changing the magnitude | size of a partition. Therefore, the versatility of the fruit color development promoting device 1B can be enhanced.

Moreover, in the case of the fruit color development promotion apparatus 1B of the type which accommodates one fruit 6a in one container body 2 as shown in FIGS. 2 to 5, the LED light source 3 is connected to the upper surface portion 8 and the lower surface portion 9 with the upper surface portion. 8 or the closer to the outer edge of the lower surface part 9, the irradiation unevenness of the light applied to the skin (surface) of the fruit 6 a that is the irradiation target accommodated in the container body 2 can be reduced. it can.
In this case, in particular, when the color development promoting process is performed using the fruit color development promoting apparatus 1B according to Example 2 on the fruit in which the degree of color development varies due to the difference in the irradiance of light, the fruit skin of the fruit 6a Since it is possible to suppress the occurrence of uneven coloring, it is possible to produce the fruit 6a with high added value more reliably. This reason will be described in detail later with reference to simulation results.

A fruit color promoting device according to Example 3 of the present invention will be described with reference to FIG.
In the fruit color development promoting device 1B according to Example 2 described above, the fruit that is the irradiation target accommodated in the container body 2 is assumed to have a shape that is relatively close to a “sphere” such as an apple. However, the shape of the fruit to be irradiated is not necessarily close to a “sphere”.
On the other hand, the inventors changed the shape of the container body of the fruit color facilitating device according to the present invention, so that the fruit color facilitating device according to the present invention can be applied to a fruit whose outer shape is not close to a “sphere”. I was able to use it. One example will be described with reference to FIG.

FIG. 6 is a conceptual diagram of a fruit color promoting device according to Example 3 of the present invention. The same parts as those described in FIGS. 1 to 5 are denoted by the same reference numerals, and description of the configuration is omitted.
The fruit color facilitating device 1C according to the third embodiment has the same configuration as the fruit color facilitating device 1B according to the second embodiment. In particular, the fruit color facilitating device 1C is disposed in the shape of the cylindrical body portion 7 and its upper and lower openings. The shapes of the upper surface portion 8 and the lower surface portion 9 are different.
More specifically, the cylindrical body portion 7 of the fruit color facilitating device 1C according to Example 3 has a shape of the upper and lower openings, for example, a pair of lengths of three opposing sides in a regular hexagon. This is a deformed hexagon with a longer length. And in the fruit coloring promotion apparatus 1C which concerns on Example 3, the shape of the upper surface part 8 and the lower surface part 9 arrange | positioned at the upper-lower opening part of the above-mentioned deformed cylinder part 7 is also the deformed cylinder part 7. The deformed hexagon is formed so as to coincide with the upper and lower openings.

  According to the fruit color development promoting device 1C according to Example 3 as described above, as shown in FIG. 6, for example, an elongated fruit 6b such as an eggplant is also accommodated in the container body 2, and the LED light source 3 The emitted light can be irradiated. Therefore, it is possible to promote the color development of the skin even for the fruit 6b whose outer shape is not close to a “sphere”. Thus, according to the fruit coloring promotion apparatus 1C according to Example 3, the versatility of the fruit coloring promotion apparatus according to the present invention can be enhanced.

Also, the shape of the upper and lower openings of the cylindrical body portion 7 (horizontal cross-sectional shape of the cylindrical body portion 7) and the shapes of the upper surface portion 8 and the lower surface portion 9 are, for example, a deformed hexagon as shown in FIG. When the rectangular shape is not used, it is possible to improve the space utilization efficiency when a large number of fruit color facilitating devices 1C are installed indoors.
In addition, about each structure other than the shape of the cylinder part 7, the upper surface part 8, and the lower surface part 9 in 1 C of fruit coloring promotion apparatuses which concern on Example 3, since it is the same as the fruit coloring promotion apparatus 1B which concerns on Example 2, it is the same. Detailed description thereof will be omitted.
Further, the shape of the upper and lower opening portions of the cylindrical body portion 7 and the shapes of the upper surface portion 8 and the lower surface portion 9 may be, for example, an ellipse or a bent shape such as an L shape. It may be. That is, whatever the shape of the fruit to be irradiated is, using the container body 2 having a shape that can completely accommodate the whole, from the vertical direction of the fruit 6b to be irradiated, By constructing the LED light source 3 so that the light in the wavelength region that promotes the color development of the fruit skin of the fruit 6b can be irradiated, the color development of the fruit skin of the object to be irradiated can be promoted.

A fruit color promoting device according to Example 4 of the present invention will be described with reference to FIG.
As shown in FIG. 1 and FIG. 6, the fruit to be irradiated includes not only a single fruit but also a fruit such as a grape in which a plurality of fruits are gathered. When it is intended to irradiate light of a wavelength region that promotes the color development of the pericarp on the entire circumference of such a fruit assembly, there is a case where the color development of the pericarp cannot be promoted efficiently by irradiation from the vertical direction of the irradiation target. In such a case, the fruit is fixed in the space by, for example, pinching the fruit shaft, and then the LED light source 3 emits light in a wavelength region that promotes color development of the skin from the side of the container body. The method to do is effective.

FIG. 7 is a conceptual diagram of a fruit color promoting device according to Example 4 of the present invention. The same parts as those described in FIGS. 1 to 6 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 7, in the fruit color facilitating device 1D according to the fourth embodiment, the cylindrical body portion 7 that is the container body 2 is disposed so as to surround the side surface of the fruit 6c to be irradiated, and this cylindrical body portion. The LED light source 3 that emits light in the wavelength region that promotes the color development of the skin is dispersed and disposed on the inner surface of 7.
Moreover, the reflection part 4 is formed in the inner surface of the cylinder part 7 so that the light emitted from the LED light source 3 can be reflected efficiently.
In addition, in the fruit coloring promotion apparatus 1D which concerns on Example 4 shown in FIG. 7, the case where the cylinder part 7 which comprises the container body 2 is comprised by the cylinder parts 7a and 7b which can be divided | segmented into two to a perpendicular direction. Although described as an example, the cylindrical body portion 7 may be an integral cylindrical shape as shown in FIGS.
In addition, although not particularly illustrated, the power distribution structure for supplying power to the LED light source 3 provided on the inner surface of the container body 2 of the fruit color development promoting device 1D according to the fourth embodiment constitutes the cylindrical body portion 7. It is accommodated in the thick part of the cylindrical part 7a, 7b. Further, the fruit color facilitating device 1D according to the fourth embodiment includes a power capturing facility (for example, a power distribution cord) for capturing power from the outside in the power distribution structure.

According to the fruit color development promoting device 1D according to Example 4 as described above, the fruit 6c to be irradiated is accommodated in the container body 2, and the color development of the skin is performed on the fruit 6c from the entire circumference on the side surface side. It is possible to irradiate light in a wavelength region that promotes the above.
According to the fruit color development promoting device 1D according to Example 4 as described above, the fruit color development promoting process is also performed on the fruit 6c that is the irradiation target that cannot be placed in a stable state in the container body 2. Can do. More specifically, for example, a wavelength that efficiently promotes the color development of the pericarp on the entire circumference using a fruit color development device according to the present invention even for a collection of a plurality of fruits such as grapes. It is possible to irradiate the region with light, thereby promoting the color development of the skin.

Although not shown in FIG. 7, an upper surface portion and a lower surface portion may be provided so as to close the upper and lower openings of the cylindrical body portion 7. In this case, the reflection part 4 is formed on the surface that forms the inner side surface of the container body 2 on the upper surface part and the lower surface part, thereby preventing the light emitted from the LED light source 3 from being dissipated and the object to be irradiated. The fruit 6c can be irradiated.
In addition, when supporting the accommodation and holding of the fruit 6c, either the upper surface portion or the lower surface portion, or both of them may not necessarily be provided. When the upper surface portion and the lower surface portion are not provided, a part of the light emitted from the LED light source 3 leaks out of the container body 2, but there is a demerit that the corresponding light cannot be effectively used. The function of the fruit color facilitating device 1D according to Example 4 is not denied.

A fruit color promoting device 1E according to Example 5 of the present invention will be described with reference to FIG.
Each of the fruit coloring promotion devices 1A to 1D according to the above-described Examples 1 to 4 was a fruit coloring promotion device of the type in which the LED light source 3 is attached in the container body 2. In the case of the fruit color facilitating devices 1A to 1D of the type in which the LED light source 3 is provided in the container body 2, the light in the wavelength region that promotes the color development of the fruit skin emitted from the LED light source 3 is maximized in the container body 2. On the other hand, there is a merit that it can be used effectively, but at the time of manufacturing these devices, a step of attaching the LED light source 3 to the inner side surface of the container body 2 is necessarily required. That is, after manufacturing the container body 2 and the LED light source 3, it is necessary to perform a process of attaching the LED light source 3 to the container body 2, and the manufacturing costs of the fruit color facilitating devices 1 </ b> A to 1 </ b> D according to Examples 1 to 4 are constant. There was a problem that it was difficult to reduce the above.
Thus, as a result of intensive research, the inventors have arranged the container body 2 that accommodates the irradiation target and the LED light source 3 that emits light in the wavelength region that promotes the color development of the fruit skin in a completely separated state. When manufacturing the fruit color development promoting apparatus according to the invention, it has been found that the operation of attaching the LED light source 3 to the container body 2 that has been considered indispensable until then can be omitted.
Here, as Example 5, an example of a fruit color facilitating device when the container body 2 and the LED light source 3 are provided separately will be described with reference to FIG.

FIG. 8A is a cross-sectional view of the fruit color facilitating device according to Example 5 of the present invention, and FIG. 8B is a cross-sectional view showing a use state of the fruit color facilitating device according to Example 5 of the present invention. The same parts as those described in FIGS. 1 to 7 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 8A, a fruit color facilitating apparatus 1E according to Example 5 is provided separately from the LED light source 3 that emits light in a wavelength region that promotes the color development of the skin, and the LED light source 3. It consists of a container body 2 that can accommodate the entire fruit 6d to be irradiated, and a reflection part 4 that efficiently reflects the light emitted from the LED light source 3 is formed on the inner surface of the container body 2. . In addition, the container body 2 includes an opening portion 14, and light emitted from the LED light source 3 is guided into the container body 2 from the opening portion 14.

In general, the light emitted from the LED light source 3 has a property that the directivity of light is high and it is difficult to diffuse to the surroundings as compared with light emitted from a conventionally known fluorescent lamp or light bulb. In the fruit color facilitating apparatus 1E according to the fifth embodiment, the light emitted from the LED light source 3 is emitted from the opening 14 formed in the container body 2 using the directivity that is the characteristic of the LED light source 3. We take in efficiently.
And the light taken in in the container body 2 is directly irradiated to the fruit 6d which is the irradiation object accommodated in the container body 2, and what was not irradiated to the fruit 6b is a container. It is reflected in the reflection part 4 formed in the inner surface of the body 2, and it is the structure irradiated to the perimeter of the surface of the fruit 6d which is a to-be-irradiated object.

According to the fruit color development promoting apparatus 1E according to Example 5 as described above, light in a wavelength region that efficiently promotes color development of the skin can be efficiently applied to the entire circumference of the surface of the fruit 6d to be irradiated. As in the fruit color development promoting devices 1A to 1D according to Examples 1 to 4 described above, the fruit skin of the fruit 6d to be irradiated can be colored efficiently.
In particular, in the case of the fruit color facilitating device 1E according to Example 5, the container body 2 and the LED light source 3 can be provided separately, so that the LED light source 3 is attached to the container body 2 when the fruit color facilitating device 1E is manufactured. The process of attaching is no longer necessary. Thereby, since the manufacturing process of the fruit coloring promotion apparatus 1E which concerns on Example 5 can be simplified, it has the effect that fruit coloring promotion apparatus 1D can be provided cheaply.

Moreover, in the case of the fruit coloring promotion apparatus 1E which concerns on Example 5 as mentioned above, especially strong light is irradiated to the fruit skin arrange | positioned at the opening part 14 side of the fruit 6d accommodated in the container body 2. FIG. Therefore, when the fruit skin of the fruit 6a has the property that the degree of color development differs according to the irradiance of light in the wavelength region that promotes the color development, there is a possibility that color unevenness may occur in the fruit skin.
Therefore, in order to irradiate the skin of the fruit 6d, which is the irradiation target, contained in the container 2 with light in a wavelength region that promotes the color development of the skin as evenly as possible, the fruit color development promoting device 1E according to Example 5 is applied. Then, for example, as shown in FIGS. 8A and 8B, a flat reflector 13 is provided in the vicinity of the opening 14 b of the container body 2, and the light emitted from the LED light source 3 is supplied to the reflector 13. Alternatively, it may be configured to be introduced into the container body 2 indirectly.
In this case, since the reflector 13 is disposed between the LED light source 3 and the fruit 6d to be irradiated, the light emitted from the LED light source 3 is blocked by the reflector 13 and is difficult to directly irradiate the fruit 6d. Moreover, since the light reflected in the reflection part 4 formed in the inner surface of the container body 2 will be irradiated in any of the fruit skin (surface) of the fruit 6d, the fruit skin of the fruit 6d which is an irradiation object Irradiation unevenness can be prevented.
In addition, when providing the flat reflector 13 in the fruit coloring promotion apparatus 1E which concerns on Example 5, the surface arrange | positioned at the fruit 6d side of the reflector 13 also has the reflectivity of the light emitted from the LED light source 3. It is desirable that

In addition, although not particularly illustrated, in the fruit color development promoting device 1E according to Example 5, instead of providing the reflector 13, the LED light source 3 is irradiated toward the inner surface of the container body 2 in the vicinity of the opening 14 of the container body 2. May be arranged to emit.
In this case, it is possible to irradiate light emitted from the LED light source 3 indirectly to the entire circumference of the fruit skin (surface) of the fruit 6 d accommodated in the container body 2 without providing the reflector 13. Also in this case, the occurrence of uneven coloring in the fruit 6d can be suppressed.
Although not particularly illustrated, the fruit color development promoting device 1E according to the fifth embodiment is configured to supply power to the LED light source 3, and to hold the LED light source 3 at a predetermined position of the container body 2. A holding structure for the LED light source 3 is provided.
Further, although not particularly illustrated, when the fruit 6d is accommodated in the container body 2 of the fruit color development promoting device 1D according to the fifth embodiment, the mounting tables 5a and 5b as described in the first and second embodiments are used. May be.
Moreover, although the opening part 14 formed in the container body 2 may be utilized as a taking-out port for taking in and out the fruit 6d, when the fruit 6d is large and the opening part 14 must be enlarged, the opening part 14 is opened. Since the amount of light dissipated from the portion 14 becomes large and the light emitted from the LED light source 3 cannot be used effectively, in such a case, another case such as making the container body 2 separable is possible. It is good to comprise so that the fruit 6d can be taken in and out from the container body 2 without using the opening part 14 by the method.

Here, a fruit color facilitating apparatus 1E according to a modification of the fifth embodiment will be described with reference to FIG. 31 (a) and 31 (b) are cross-sectional views of a fruit color facilitating device according to a modification of the fifth embodiment. The same parts as those described in FIGS. 1 to 8 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIGS. 31 (a) and 31 (b), the fruit color development promoting device 1F according to the modified example of Example 5 is replaced with the reflector 13 in the fruit color development promoting device 1E according to Example 5 shown in FIG. In addition, for example, a plate-like or film-like light diffuser 15 is disposed in the opening 14 of the container body 2.
In this case, the light emitted from the LED light source 3 is prevented from being directly irradiated to the skin (surface) of the fruit 6d to be irradiated, and as shown in FIGS. 31 (a) and 31 (b), Light emitted from the LED light source 3 at the opening 14 of the container body 2 can be incident on the container body 2 while being diffused.
According to the fruit color facilitating device 1F according to the modified example of Example 5 as described above, an effect equivalent to that of the fruit color facilitating device 1E according to Example 5 of the type including the reflector 13 as shown in FIG. 8 is exhibited. The configuration of the apparatus can be simplified. That is, the structure for attaching the reflector 13 to the LED light source 3 or the container body 2 can be omitted as compared to the fruit color development promoting device 1E according to the fifth embodiment.
Therefore, manufacture and maintenance of the fruit color facilitating device 1F according to the modified example of Example 5 can be further facilitated. In addition, the manufacturing cost of the fruit color development promoting device 1F according to the modification of the fifth embodiment can be further reduced.

Here, the fruit color facilitating devices 1A and 1B according to Examples 1 and 2 will be described with reference to FIG.
FIG. 9 shows the uniformity of irradiation light with respect to the fruit to be irradiated, the manufacturing cost of the apparatus, and the space utilization efficiency when installing a plurality of apparatuses indoors in each fruit color development promoting apparatus according to the present invention. It is the graph compared. More specifically, FIG. 9 shows that the fruit color facilitating device 1A according to the first embodiment and the tube portions 7 of the fruit color facilitating device 1B according to the second embodiment are respectively formed into a square tube, a hexagonal tube, an octagonal tube, and a cylinder. It is the graph which compared the uniformity of the irradiation light with respect to the fruit which is a to-be-irradiated object, the manufacturing cost of an apparatus, and the space utilization efficiency at the time of installing several apparatuses indoors in each case. In addition, the magnitude | size of the circle in FIG. 9 represents the magnitude of the manufacturing cost at the time of manufacturing each fruit coloring promotion apparatus.

As shown in FIG. 9, the uniformity of light irradiated onto the fruit peel (surface) of the subject to be irradiated (high possibility of being uniform) relates to Example 1 as shown in FIG. 1. The case of the fruit color development promoting apparatus 1A is the highest, and in the fruit color development promotion apparatus 1B according to Example 2, as the multi-angle in the horizontal cross section of the cylindrical body part 7 increases, the fruit skin (surface) to be irradiated is increased. It is considered that the uniformity of the light irradiated on the surface increases.
On the other hand, the production cost of each fruit color promoting device according to the present invention is expected to be highest in the fruit color promoting device 1A according to Example 1, which is considered to have the highest uniformity of irradiation light. Moreover, in the fruit coloring promotion apparatus 1B which concerns on Example 2, the tendency for the manufacturing cost of an apparatus to become high was recognized as the multi-angle in the horizontal cross section of the cylinder part 7 increased.
On the other hand, the space utilization efficiency in the case where a plurality of each of the fruit color facilitating devices according to the present invention as described above are installed indoors is a rectangular tube 7 of the fruit color facilitating device 1B according to Example 2. The case is the highest, and it is considered that the cylinder 7 is then a hexagonal cylinder. In the case where the cylindrical body portion 7 of the fruit color development promoting device 1B according to the second embodiment is a square tube or a hexagonal tube, the fruit color development promotion device 1B is arranged without any gap in the vertical direction or the vertical direction. It is because it can do.
Furthermore, according to the simulation result described in the latter part, in the case of the fruit color facilitating device 1B according to the second embodiment, the horizontal cross-sectional shape of the cylinder 7 is made polygonal rather than a quadrangle so as to be close to a circle. It became clear that it became easy to suppress generation | occurrence | production of the irradiance nonuniformity in the peel (surface) of a certain fruit.
Therefore, based on the simulation results shown in FIG. 9 and the latter stage as described above, the fruit color facilitating apparatus 1A according to Example 1 can be used for the purpose of producing small-scale and particularly high value-added fruits. Desirably, when a large amount of high-value-added fruit is to be produced on a large scale, it can be said that it is desirable that the cylindrical body portion 7 be a hexagonal cylinder or an octagonal column in the fruit color development promoting device 1B according to the second embodiment. .
As described above, the fruit color facilitating apparatus according to the present invention can take various forms, but it is difficult to determine the superiority or inferiority of the apparatus, and the optimal form of the fruit color facilitating apparatus is considered to change depending on the purpose of use of the apparatus.

Further, although not particularly illustrated, the fruit color facilitating devices 1A, 1E, and 1F according to the first and fifth embodiments may also be provided with a connector so that a plurality of devices can be connected and installed. In this case, the space utilization efficiency when installing a large number of devices can be enhanced.
In addition, in the fruit coloring promotion apparatus 1A-1F which concerns on Examples 1 thru | or 5 as mentioned above, by wrapping the fruit which performs a coloring promotion process in the state which shielded natural sunlight by wrapping in bags, such as paper, beforehand. Moreover, the color development at the time of performing a color development acceleration | stimulation process using the fruit color development apparatuses 1A-1F which concern on Example 1 thru | or 5 can be improved.
Moreover, in the fruit coloring promotion apparatus 1A-1F which concerns on Examples 1 thru | or 5 as mentioned above, when the fruit which performs a color development acceleration | stimulation process is made especially with phosphorus, the light emitted from LED light source 3 is 430-520 nm. Blue light having light emission in the wavelength range, purple light having light emission in the wavelength range of 370 to 430 nm, or near ultraviolet light having light emission in the wavelength range of 330 to 400 nm alone, or these wavelengths By irradiating a combination of at least two kinds of light having a range of light emission, it was possible to efficiently develop the color of apple peels.

When the arrangement of the LED light source 3 is changed with respect to the fruit color facilitating devices 1A to 1D according to the first to fourth embodiments of the present invention, the light emitted to the fruit skin (surface) to be irradiated is uniform. A simulation was conducted on how the sex changes. Here, the conditions and results will be described with reference to FIGS.
FIG. 10 is a table summarizing the conditions for performing a simulation related to the fruit color facilitating apparatus according to the present invention.
As shown in FIG. 10, in this simulation, the shape of the container is a sphere, a quadrangular prism, a hexagonal prism, an octagonal prism, a cylinder, and a deformed hexagonal prism, and by changing the arrangement of the LED light sources in each shape, We investigated how the irradiance of light on the surface of the irradiated object changed. In this simulation, 20 types of conditions with different patterns 1 to 20 were set.
More specifically, in the patterns 1 to 3, the shape of the container body was made spherical, and the LED light sources were arranged in a state of being evenly distributed on the inner surface thereof. In Patterns 4 to 6, the shape of the container body was a quadrangular prism, and LED light sources were disposed on the upper surface portion and the lower surface portion thereof. In Patterns 7 to 9, the shape of the container was a hexagonal column, and LED light sources were arranged on the upper surface and the lower surface. In patterns 10 to 12, the shape of the container was an octagonal column, and LED light sources were arranged on the upper and lower surfaces. In patterns 13 to 15, the shape of the container body was a cylinder, and LED light sources were arranged on the upper surface portion and the lower surface portion. In the patterns 16 to 18, the shape of the container body was changed to a deformed hexagonal column, and LED light sources were arranged on the upper surface portion and the lower surface portion thereof. In the patterns 19 and 20, the shape of the container was a hexagonal column, and an LED light source was disposed on the inner surface of the cylinder 7.
Moreover, the irradiation object accommodated in the container body 2 in each of the patterns 1 to 20 is a sphere having a radius of 50 mm, and the irradiance of light assumed to be irradiated on the surface is shown in the graph.
In the table of FIG. 10, the figure numbers corresponding to the respective simulation results are also shown.

[1] When the shape of the container body is a sphere (a) in FIGS. 11 to 13 is a conceptual diagram showing the shape of the container body, the arrangement of the irradiation target in the container body, and the arrangement condition of the LED light source, (B) is a graph which shows the simulation result in each condition.
In pattern 1, a meridian was drawn every 45 ° on the inner surface of the spherical container body, and a latitude line was drawn every 30 °, and one LED light source was placed at the intersection. In Pattern 2, a meridian is drawn every 90 ° on the inner surface of the spherical container body, and a latitude line is drawn every 30 °, and one LED light source is arranged at the intersection. In Pattern 3, a meridian was drawn every 60 ° on the inner surface of the spherical container body, and a latitude line was drawn every 30 °, and one LED light source was placed at the intersection. In addition, the graph shown by FIG. 11 thru | or 13 (b) showed the change of the irradiance from the equator which pinched | interposed the north pole in the x coordinate direction of the surface of the sphere which is an irradiation object, to the equator. In addition, the irradiance at the point “0” on the x coordinate in the graphs of FIGS. 11 to 13 (b) indicates the irradiance at the north pole position of the spherical irradiation target shown in FIGS. 11 to 13 (a). ing. The matters regarding the graph showing the simulation result as described above are the same in the graph showing the simulation result shown in each of FIGS.
As shown in FIGS. 11 to 13 (b), in each of the patterns 1 to 3, the LED light source is arranged in a state of being evenly distributed on the inner side surface of the container body, so that the irradiance varies on the surface to be irradiated. However, there was no significant irradiance bias.

[2] When the shape of the container body is a quadrangular prism (a) in FIGS. 14 to 16 is a conceptual diagram showing the shape of the container body and the arrangement of the irradiation target, and (b) is an LED light source in (a). It is a top view which shows the specific arrangement | positioning of the LED light source in the surface where this is arrange | positioned, (c) is a graph which shows the simulation result in each conditions. In addition, the hatched part in FIGS. 14 to 16 (a) means that the LED light source is disposed on the surface.
In the pattern 4, LED light sources are arranged at regular intervals on the diagonal line between the upper surface portion and the lower surface portion of the quadrangular prism. In the pattern 5, the LED light sources are arranged so as to be closer to the outer periphery of the upper surface portion and the lower surface portion on the diagonal line of the upper surface portion and the lower surface portion of the quadrangular prism. Furthermore, in the pattern 6, the tendency of the pattern 5 was made more remarkable.
As shown in FIGS. 14 to 16 (c), when the shape of the container body is a quadrangular prism, the position of the North Pole on the surface of the irradiation target even when the arrangement of the LED light sources on the upper surface portion and the lower surface portion is changed. There was a tendency for irradiance to increase in the surrounding area.
Although not particularly shown in the drawings, a simulation was also carried out in the case where the shape of the container body was a quadrangular prism and 25 LED light sources were equally arranged in a grid on each of the upper surface portion and the lower surface portion. There was a tendency for the irradiance to increase around the position of the North Pole on the surface of the irradiated object.
Therefore, in the case where the container body is a quadrangular prism, the light used to irradiate the surface of the irradiated object is considered to have the highest space utilization efficiency when installing a plurality of fruit color facilitating devices 1B according to Example 2. The result that it was a little difficult to make uniform was obtained.

[3] When the shape of the container body is a hexagonal column (a) in FIGS. 17 to 19 is a conceptual diagram showing the shape of the container body and the arrangement of the irradiation target, and (b) is an LED light source in (a). It is a top view which shows the specific arrangement | positioning of the LED light source in the surface where this is arrange | positioned, (c) is a graph which shows the simulation result in each conditions. In addition, the hatched part in FIG. 17 thru | or 19 (a) means that the LED light source is arrange | positioned in the surface.
In Pattern 7, LED light sources were arranged at regular intervals on the diagonal line between the upper surface portion and the lower surface portion of the hexagonal column. In the pattern 8, the LED light sources are arranged on the diagonal line of the upper surface portion and the lower surface portion of the hexagonal column and the LED light sources become denser as they approach the outer edges of the upper surface portion and the lower surface portion. In pattern 9, the tendency of pattern 8 was made more prominent.
As shown in FIGS. 17 to 16 (c), when the shape of the container body is a hexagonal column, unlike the case of the previous square column, the LED light source is denser as it approaches the outer edge on the upper surface portion and the lower surface portion. It became clear that the light can be irradiated more evenly on the surface of the irradiation target by arranging.

[4] When the shape of the container body is an octagonal column (a) in FIGS. 20 to 22 is a conceptual diagram showing the shape of the container body and the arrangement of the irradiation target, and (b) is the LED light source in (a). It is a top view which shows the specific arrangement | positioning of the LED light source in the surface where this is arrange | positioned, (c) is a graph which shows the simulation result in each conditions. Note that the hatched portions in FIGS. 20 to 22 (a) mean that the LED light source is disposed on the surface.
In the pattern 10, LED light sources are arranged at regular intervals on the diagonal line between the upper surface portion and the lower surface portion of the octagonal prism. Moreover, in the pattern 11, it arrange | positioned so that an LED light source may become dense as it approaches the outer edge of an upper surface part and a lower surface part on the diagonal of the upper surface part and lower surface part of an octagonal prism. In the pattern 12, the tendency of the pattern 11 is made more remarkable.
As shown in FIGS. 20 to 22 (c), when the shape of the container body is an octagonal prism, the LED light sources are densely arranged on the upper surface portion and the lower surface portion as they approach the outer edge, similarly to the case of the hexagonal column. It was revealed that the light is evenly irradiated on the surface of the irradiation target.

[5] When the shape of the container body is a cylinder (a) in FIGS. 23 to 25 is a conceptual diagram showing the shape of the container body and the arrangement of the irradiation target, and (b) is an LED light source in (a). It is a top view which shows the specific arrangement | positioning of the LED light source in the surface arrange | positioned, (c) is a graph which shows the simulation result in each condition. In addition, the hatched part in FIGS. 23 to 25 (a) means that the LED light source is disposed on the surface.
In the pattern 13, LED light sources were arranged at the same coordinate position as the pattern 6 shown in FIG. In the pattern 14, LED light sources are arranged at the same coordinate position as the pattern 9 shown in FIG. In the pattern 15, the LED light source is arranged at the same coordinate position as the pattern 12 shown in FIG.
The previous pattern 6 and the pattern 13 this time differ only in the shape of the container. When comparing FIG. 23C and FIG. 16C, the irradiance unevenness generated on the surface of the irradiation target is slightly reduced in the pattern 13 as compared with the pattern 6. For this reason, in the fruit color development promoting apparatus 1B according to Example 2, the irradiance unevenness of the light irradiated on the surface of the irradiation target is mitigated by making the planar shape of the container body polygonal and finally bringing it into a circular shape. It is thought that the effect to do can be exhibited.
Further, when FIG. 24B is compared with FIG. 25B, the pattern 14 and the pattern 15 are considered to be in a state in which the LED light sources are more dispersed, but the irradiation target. It can be said that the pattern 14 is higher in the effect of alleviating unevenness in the irradiance of the light irradiated on the surface of the pattern 14. Therefore, in the fruit color development promoting device 1B according to Example 2, the unevenness of the irradiance of the light irradiated on the surface of the irradiation target is reduced by arranging the LED light sources densely as the outer edges of the upper surface portion and the lower surface portion are approached. It is thought that the effect to do is demonstrated.

[6] When the shape of the container body is a deformed hexagonal column (a) in FIGS. 26 to 28 is a conceptual diagram showing the shape of the container body and the arrangement of the irradiation target, and (b) is the LED in (a). It is a top view which shows the specific arrangement | positioning of the LED light source in the surface where a light source is arrange | positioned, (c) is a graph which shows the simulation result in each condition. In addition, the hatched part in FIG. 26 thru | or 28 (a) means that the LED light source is arrange | positioned in the surface.
In the pattern 16, the LED light source was arrange | positioned for every fixed space | interval on the diagonal of the upper surface part and lower surface part of a deformation | transformation hexagonal prism. Moreover, in the pattern 17, it arrange | positioned so that an LED light source may become dense as it approaches the outer edge of an upper surface part and a lower surface part on the diagonal of the upper surface part and lower surface part of a deformation | transformation hexagonal column. In the pattern 18, the tendency of the pattern 17 was made more remarkable.
As shown in FIGS. 26 to 28 (c), even when the shape of the container body is a deformed hexagonal column, the LED light sources are closely arranged on the upper surface portion and the lower surface portion as they approach the outer edge thereof, so that the object to be irradiated is arranged. It became clear that the surface could be illuminated more evenly.

[7] In the case of irradiating light from the side surface of the container body FIGS. 29 and 30 are both conceptual diagrams showing the shape of the container body and the arrangement of the irradiation target, and (b) in FIG. It is a top view which shows the specific arrangement | positioning of the LED light source in the surface where an LED light source is arrange | positioned, (c) is a graph which shows the simulation result in each condition. 29 and 30 (a) indicates that the LED light source is disposed on the surface of the hatched portion.
In the pattern 19, eight LED light sources were uniformly distributed on all side surfaces inside the hexagonal column. In the pattern 20, 21 LED light sources were evenly dispersed on all side surfaces inside the hexagonal column.
In FIG. 29 (c) and FIG. 30 (c), since the scale in the Y-axis direction is different, it is somewhat difficult to read the tendency. However, when irradiating light from the side of the container body, an LED light source is installed. Even if the LED light sources are dispersed on the surface, it is clear that the increase in the number of LED light sources installed on one side surface of the container body is unlikely to contribute to alleviating irradiance unevenness on the surface of the irradiated object. became.
Further, although not particularly illustrated, when the shape of the container body is a hexagonal column and the same number of LED light sources as in the case of the pattern 19 are disposed on the side surface, the LED light sources are arranged at the outer edges of the upper surface portion and the lower surface portion of the container body. A simulation was also performed for the case where the arrangement was denser as the distance closer to. In this case, compared with the case of the previous pattern 19, the tendency for the generation | occurrence | production of the irradiance nonuniformity of the light in the to-be-irradiated object surface to be suppressed was recognized. Further, as in the case of the previous patterns 19 and 20, the absolute amount of light irradiated on the peripheral side surface of the irradiation target tends to be larger than the absolute amount of light irradiated on the upper and lower surfaces of the irradiation target. Since it was recognized, depending on the type of fruit to be irradiated and the method of placing the fruit, the fruit peels appear more beautifully than when LED light sources are placed on the upper and lower parts of the container body. In some cases, it may be possible to

Therefore, according to the simulation result of this time, particularly in the fruit color development promoting device 1B according to the second embodiment, the horizontal cross section of the container body is made polygonal more than a quadrangle and made close to a circle, so that the light on the surface of the irradiation target is reflected. The effect of mitigating irradiation unevenness can be expected. In particular, in the fruit color facilitating apparatus 1B according to the second embodiment, when the LED light sources are attached to the upper surface portion and the lower surface portion of the container body, the LED light sources are densely arranged as approaching the outer edges of the upper surface portion and the lower surface portion. It is considered that the effect of mitigating unevenness of light irradiation on the surface of the irradiation target can be exhibited.
Furthermore, from the simulation results of the pattern 9 and the pattern 19 described above, in the case of the fruit color facilitating apparatus 1B according to Example 2, the upper surface portion 8 of the container body 2 and the case where the LED light source 3 is attached to the side surface of the container body 2 It has been clarified that when the LED light source 3 is attached to the lower surface portion 9, it is easier to suppress the occurrence of uneven irradiance on the surface of the irradiation target accommodated in the container body 2.
