(Driving Method of Visual Therapy Apparatus Using Visual Therapy Apparatus 100) The driving method of the visual therapy apparatus using the visual therapy apparatus 100 according to the present embodiment having the above configuration is performed according to the following procedure.

First, the artificial soil 2 containing a fragrance such as hinokitiol is filled in the container 1a, and a plant is planted with its root held above the artificial soil 2 filled. At this time, by holding the roots in the artificial soil 2, the roots are planted at a distance of about 4 cm from the bottom of the container 1a.

Next, the power of the light emitting unit 41 is turned on,
The artificial soil 2 is illuminated with light from the plurality of LEDs 6r, 6g, and 6b via the light transmitting portion on the bottom surface of the container 1a. LED

(Operation of the Visual Therapy Apparatus 100) According to the visual therapy apparatus 100 according to the present embodiment, the artificial soil 2 is irradiated with light by the three-color LEDs 6r, 6g, and 6b. By emitting the diffusely reflected light from the side surface of the container 1a to the outside, a visual therapy effect by illumination like illumination can be realized. In addition, the fragrance compounded in the artificial soil evaporates only a small amount by the weak heat of the LEDs 6r, 6g, and 6b, so that the fragrance can provide an aroma therapy effect.

In the case of 0, light is emitted to the transparent artificial soil 2 by the light emitting unit 41, and irregular reflection by the artificial soil 2 and the air bubbles 2a is reduced
By observing from outside, the dry state of the artificial soil 2 filled in the container portion 1a and the water level L of the pore water present in the artificial soil 2 can be grasped. That is, as described above, irregular reflection on the surface of the artificial soil 2 is easily seen above the water level L of the pore water, and irregular reflection on the bubbles 2a in the pore water is easily seen below the water level L,
By observing the state of these irregular reflections, the state of pore water and the dry state of the artificial soil 2 can be grasped.

Further, the visual therapy device 1 according to the present embodiment
According to 00, since a high-water-absorbing high-molecular polymer is used as the artificial soil 2, the artificial soil 2 itself can be made to have water absorption, and water can be retained for a long time. Moreover, since the artificial soil 2 is transparent, the plant 3
Of the root 31 can be easily observed. Therefore, breeding and care of the plant planted in the visual therapy device 100 can be facilitated.

The visual therapy device 10 according to the present embodiment
According to 0, since the light emitting unit 41 is configured to be stored in the storage section 4 at the lower part of the container main body, the occupied area required for installing the visual therapy device 100 can be reduced.

Therefore, the visual therapy device 1 according to the present embodiment
According to 00, an illumination-like visual therapy effect by diffuse reflection of the artificial soil 2, a relaxation effect by plant ornamentation, and an aroma therapy effect by a fragrance blended into the artificial soil can be obtained by a single device. Visualization of effective healing effects etc. while reducing the occupied area
Aroma therapy effect can be obtained.

[0075] For example, three visual therapy devices were prepared for lighting only blue, lighting only red, and lighting only green, and were used for plant research such as a control experiment comparing the effect of light color on plant growth. It is also possible to use. In this case, it is also possible to examine the effects of the irradiation timing and the irradiation time of the lighting body.

(Meaning of Using LED) Here, the reason why the LED is used as the light source in the present embodiment will be described in detail. FIGS. 6A and 6B show the visual therapy apparatus 100 according to the present embodiment in which the LED 6r is used as an illumination unit.
It is the table | surface and the graph showing the result of the control experiment performed in order to show the effect by using 6g and 6b. In this experiment, artificial soil 2 was placed in a pot (container 1a).
, And the temperature rise of the artificial soil 2 in the pot when the artificial soil 2 was irradiated with an LED or a bulb from the bottom was measured.

The experimental method will be described in detail. Three pots filled with the same amount of artificial soil 2 are prepared. In the first pot, the illuminance is the same as that of the LED in the second pot. Lux), using three bulbs (DC12V, 4.3W, three DC9V, 1.0A used) whose power supply voltage is adjusted so that the same LED (color) as in the present embodiment is used for the second pot. Unit) 6r,
Using 6g and 6b, the relationship between the elapsed time and the temperature change in the pot (bottom or center) was measured under the condition that no light emitting means was provided in the third pot.

As shown in FIGS. 9A and 9B, the temperature of the first pot using a light bulb increased with the lapse of time, and as shown in FIGS. In the second pot using an LED (color unit), the temperature reached 65 ° C., and even at the center (4.5 cm from the bottom surface).
The temperature has risen only from 0 to 1.5 ° C. Note that the room temperature during the experiment was kept constant, as shown by the measurement results for the third pot without the light emitting means.

As is clear from the above experimental results, when a light bulb is used as the lighting means, the light bulb emits heat together with light, so that the temperature of the artificial soil in the container rises. On the other hand, when an LED is used as the light emitting means, such a remarkable temperature rise does not occur.

According to the opinion of the Agricultural Experiment Station and the like, the temperature limit of the root portion of the plant is 35 ° C. In the present invention, since the temperature rise is very small, irradiation of light by the light emitting means does not adversely affect the growth of the plant. On the other hand, as shown in the above experimental results, in the configuration disclosed in the cited document, the temperature of the artificial soil was 65 ° C. at the bottom.
Up to 40 ° C in the center,
In this configuration, it is considered difficult to grow plants properly.

If the temperature in the container 1a rises remarkably, there is a problem that algae and bacteria are generated early in the artificial soil 2. That is, in the configuration using an incandescent bulb as the lighting means, the temperature rise is remarkable, so that algae and bacteria are generated at an early stage, the transparency of the artificial soil is reduced, and the dried state of the artificial soil and the growth state of the roots are observed. In addition to the difficulties, and a problem arises that the appearance is impaired.

On the other hand, in the visual therapy device 100 according to the present embodiment, since the temperature rise due to light irradiation is stopped at 1.0 to 1.5 ° C., the generation of algae and bacteria is reduced, and the artificial soil for a long time is reduced. Transparency can be maintained.

In comparison with the configuration using an incandescent light bulb in terms of power consumption, when the light bulb is used as the light emitting means,
In order to obtain illuminance equivalent to that of the ED, DC 9 V requires 1 A, that is, 9 W of power consumption. In contrast, with LEDs,
In order to obtain the same illuminance, the power is 12 V and 0.1 A, that is, only about 1 W in electric power. Therefore, it can be said that it is difficult to achieve low power in a configuration using an incandescent light bulb.

Further, the color of an LED is based on a specific wavelength spectrum generated when electrons and holes are recombined in an applied semiconductor device. The principle is different.

In the LED, since a wavelength spectrum in a predetermined range (peak) is generated depending on the characteristics of the element, various colors are realized by combining a plurality of elements. Light from the LED has directivity due to the wavelength spectrum of the predetermined peak. That is, L
The color light emitted from the ED has different wavelength characteristics and directivity for each color.

In the visual therapy device 100 according to the present embodiment, the artificial soil 2 is irradiated with various colors of light, and reflected and refracted many times to cause irregular reflection. In order to cause the reflection and refraction by the artificial soil 2 to occur more effectively over the entire artificial soil 2 without increasing the amount of light, the wavelength characteristics and directivity of the light of the LED play an important role. Fulfill.

On the other hand, when trying to obtain the same directivity as the visual therapy device 100 according to the present embodiment by using a configuration using a light bulb, the following problem is expected to occur. That is, since light emitted by a light bulb does not have directivity, if it is desired to obtain directivity equivalent to that of an LED, it is necessary to provide a light condensing means such as a lens, which complicates the apparatus and reduces manufacturing costs. May rise.

When a cellophane or a filter is provided in order to obtain color light of various wavelength spectra using a light bulb or the like, the structure for that purpose is of course complicated.
It is expected that a further increase in temperature will occur. That is, since a light bulb or the like emits light in which various wavelength spectra are mixed, in order to extract a specific wavelength spectrum from the light, an unnecessary wavelength spectrum is absorbed by a cellophane or a filter, and the specific wavelength spectrum is absorbed. Only the spectrum will be transmitted. At this time, the temperature of the cellophane and the like rises due to the unnecessary wavelength spectrum absorbed by the cellophane and the like. In addition, since the amount of light passing therethrough is reduced by absorbing an unnecessary wavelength spectrum, when the above-described directivity is also required, the amount of light from the light source must be further increased, and the above-mentioned temperature rise becomes more remarkable. At the same time, it is difficult to realize power saving.

The visual therapy device 100 according to the present embodiment is configured in view of these problems, and uses several types of LEDs 6r, 6g, and 6b as illumination means, and performs one-shot on the surface of artificial soil.
While irradiating light so that the illuminance of 70 lux,
Root of the plant is 4cm from the bottom of the container part 1a by artificial soil 2.
By separating as described above, it is possible to irradiate colored light having different wavelength characteristics and directivity over the entire artificial soil 2 without causing a significant temperature rise of the artificial soil 2,
It is possible to avoid adversely affecting the growth of plants and prevent algae and bacteria from occurring at an early stage.

(Modification) In the first embodiment described above, the following changes can be made. That is, as shown in FIG. 7, a light shielding film 5a for shielding light of a specific wavelength may be attached to the partition plate 5 at the bottom of the container 1a. In the present embodiment, the light-shielding film 5a is arranged substantially at the center of the partition plate 5 corresponding to the position where the plant 3 is planted.

According to the light shielding film 5a, the LED 6
This can reduce the rise in temperature of the artificial soil 2 around the plant 3 by blocking light from the plant 3, thereby avoiding adverse effects on the growth of the plant 3 due to the temperature rise.
As the shielding film 5a, a material that does not transmit light at all can be used, or a material that reflects light may be used. When a material that reflects light is used, it is preferable that the light from the LED 6 be reflected downward with the reflection surface facing downward.

When wasabi oil and hinokitiol are used, an aroma therapy effect due to the fragrance can be expected.

It is needless to say that these antibacterial substances may be incorporated into the artificial soil 2 containing no nutrients outside the partition 11. In long-term plant cultivation, bacteria such as bacteria may propagate even in artificial soil containing no nutrients, and the propagation of these bacteria may make it difficult to see the root 31 of the plant 3 inside.
