As illustrated in figures 19 and 20, the light projected from the light source 50 of lighting device 7 makes irradiation area (range of exposures) expand along with going to extend out gradually towards dish for cultivating 3.As shown in (A) of Figure 20, in the surperficial 20a of the main part 20 of the cap 12 of dish for cultivating 3, there is the region be irradiated by light and the region be not irradiated by light.Specifically, irradiate light by the ad-hoc location between 3 medium accommodation sections 26 on 3 medium accommodation sections 26 of the accommodation culturing pot 9 on alignment surface 20a or surperficial 20a, around medium accommodation section 26 and this medium accommodation section 26, create the 1st region A1.At this, the 1st region A1 is the region of each irradiation area synthesis that the light projected by the multiple light sources 50 had from lighting device 7 irradiates.

The 2nd region A2 in the outside of the 1st region A1 is not penetrated by the illumination that the light source 50 from lighting device 7 projects substantially.Namely, be built in the light source 50 of lighting device 7 by carrying out the setting of optical axis direction, the luminous intensity distribution conversion of diffusing light, and make the region of the surperficial 20a of through light and the diffusing light arrival main part 20 projected from light source 50 concentrate on the scope of the 1st region A1 of the surrounding comprising medium accommodation section 26 and this medium accommodation section 26.The lighting device 7 of built-in light source 50 is installed on framework 5 in such a way, the intensity of light of the 1st region A1 of irradiation on dish for cultivating 3 or the value of light quantity is made to be greater than the intensity of light or the value of light quantity of the 2nd region A2 irradiated on dish for cultivating 3,1st region comprises medium accommodation section 26 and medium accommodation section 26 around, and the 2nd region A2 is positioned at the outside of the 1st region A1.Thus, in the surperficial 20a of the main part 20 of the cap 12 of dish for cultivating 3, comprise the effective photon hypothesis of photosynthesis [μm ol/m of the 1st region A1 of the surrounding of medium accommodation section 26 ²/ s] higher than the effective photon hypothesis of photosynthesis [μm ol/m of the 2nd region A2 in the outside of the 1st region A1 ²/ s].

Under another viewpoint, the medium accommodation section 26 of the culturing pot 9 in dish for cultivating 3 is configured in the larger region of the value of the intensity of light or light quantity.Thus, light can be made effectively to irradiate the culturing pot 9 (medium) in the medium accommodation section 26 being contained in dish for cultivating 3.

As mentioned above, in the present embodiment, in the surperficial 20a of the main part 20 of the cap 12 of dish for cultivating 3, the effective photon hypothesis of photosynthesis [μm ol/m of the 1st region A1 of the surrounding of medium accommodation section 26 is comprised ²/ s] be greater than the effective photon hypothesis of photosynthesis [μm ol/m of the 2nd region A2 in the outside of the 1st region A1 ²/ s].Thus, in plant cultivating device 1, illumination can be effectively made to penetrate in planting the culturing pot 9 being implanted with plant.Therefore, light can not be irradiated to the 2nd region A2 beyond the 1st region A1 at plant growth place substantially, can suppress dispersing of light, and the amount therefore without the need to the light projected by light source 50 is increased to more than necessary degree.Thus, in plant cultivating device 1, the light projected from lighting device 7 became bright and can be inhibited, and can guarantee interior decoration.In addition, light can not be irradiated to region beyond the 1st region A1 at plant growth place (neighboring area outside the 2nd region A2 and dish for cultivating 3) substantially, therefore, the irradiation of the unnecessary light being unprofitable to plant growth can be suppressed, therefore can seek energy-saving.

In addition, in plant cultivating device 1, because cultivation space S is open, therefore, heat can be suppressed to be held in cultivation space S.Thus, condensation can be prevented, can prevent from destroying interior decoration.In addition, owing to taking a breath fully, therefore, the increase of oxygen concentration can be suppressed, therefore can seek Promoting plant growth.

In the present embodiment, the mounting portion 40 of framework 5 is provided with dish fixed part 41.Thus, when dish for cultivating 3 is embedded in dish fixed part 41, dish for cultivating 3 to be limited the movement in the direction such as in the horizontal direction in mounting portion 40 by locating.Therefore, even if repeatedly load and unload, dish for cultivating 3 also can not change relative to the installation site of framework 5, and inherently scheduled constant position, therefore, the 1st region A1 of light on dish for cultivating 3 projected from lighting device 7 is always in same position.Therefore, even dismountable dish for cultivating 3, also can effectively make light always irradiate in plant.

(variation)

Then, the variation of the 1st embodiment is described.The structure of the lighting device of the plant cultivating device of variation is different from the 1st embodiment.Figure 21 is the figure of the light that the lighting device of the plant cultivating device schematically showing another embodiment projects.Figure 22 schematically shows that the light irradiated by lighting device is at the figure cultivating the irradiation area on each horizontal plane in space.In fig. 22, A represents the irradiation area of the light on the surperficial 20a (face along the a-a line of Figure 21) of the main part 20 (cap 12) of dish for cultivating 3, and B represents the irradiation area of the light on the middle aspect MS2 (face along the b-b line of Figure 21) of cultivation space S.

As shown in figure 21, lighting device 7 from 3 light sources (not shown) to dish for cultivating 3 projection light.As shown in figure 22, in the cap 12 of dish for cultivating 3, two culturing pots 9 (medium accommodation section 26) form a line by main part 20 with being separated with predetermined distance in left-right direction.As shown in figure 22, the region that medium accommodation section 26 is located at light overlap on the surperficial 20a of main part 20 that 3 light sources project is configured.

As shown in figure 22, irradiate light by the specific position between two the medium accommodation sections 26 accommodating culturing pot 9 on alignment surface 20a, around medium accommodation section 26 and this medium accommodation section 26, create the 1st region A1.At this, the 1st region A1 is the region of each irradiation area synthesis that the light gone out by 3 light source projects had from lighting device 7 irradiates.

The 2nd region A2 in the outside of the 1st region A1 is not penetrated by the illumination that 3 light source projects from lighting device 7 go out substantially.Namely, 3 light sources by carrying out the setting of optical axis direction, the luminous intensity distribution conversion of diffusing light, and make the region of the surperficial 20a of through light and the diffusing light arrival main part 20 projected from light source 50 concentrate on the scope of the 1st region A1 of the surrounding comprising medium accommodation section 26 and this medium accommodation section 26.The lighting device 7 being built-in with light source is installed on framework 5 as follows, irradiation is made to be greater than the intensity of light or the value of light quantity of the 2nd region A2 of the cap 12 irradiated in dish for cultivating 3 in the intensity of light of the 1st region A1 of the cap 12 of dish for cultivating 3 or the value of light quantity, 1st region A1 comprises medium accommodation section 26 and medium accommodation section 26 around, and the 2nd region A2 is positioned at the outside of the 1st region A1.Further, carry out the setting of the optical axis direction of 3 light sources, the luminous intensity distribution conversion of diffusing light, enter in the scope of each irradiation area overlap of 3 light sources in the 1st region A1 to make two medium accommodation sections 26.

The angle of the diffused light in the light that projects of luminous intensity distribution converter section adjustment light source of lighting device 7, spills into the outside of plant cultivating device 1 to avoid the irradiation area of the light of the cap 12 of dish for cultivating 3 to expand.In addition, by arranging optical axis direction setup unit described later, and the direction of the light that light source projects can be set, with the region making culturing pot 9 (medium accommodation section 26) be positioned at the shadow surface overlap of 3 light sources.

[the 2nd embodiment]

Then, the 2nd embodiment is described.The structure of the light source of the 2nd embodiment is different from the 1st embodiment.(a) of Figure 23 is the vertical view of the lighting device of the plant cultivating device representing the 2nd embodiment, and (b) of Figure 23 is the figure when top view dish for cultivating.

First the structure of dish for cultivating 3 is described.In the cap 12 of the dish for cultivating 3 of present embodiment, culturing pot 9 (medium accommodation section 26) is configured to row with being separated with predetermined distance in left-right direction by main part 20.As shown in (c) of Figure 13 and (d) of Figure 13, dish for cultivating 3 also can have structure cap 12A and culturing pot 9A being set to one.

Lighting device 7A has the 1st light source 50a of the light that can send blue component and can send the 2nd light source 50b of light of red color components.Substrate 52 and the structure of luminous intensity distribution converter section 54 and identical in the 1st embodiment.1st light source 50a is the blue LED of the light of the blue component that can send the wavelength such as with 420nm ~ 470nm.In addition, as shown in figure 24, the 1st light source 50a also can be the white light-emitting diode of the wavelength comprising blue component.2nd light source 50b is the red light emitting diodes of the light of the red color components that can send the wavelength such as with 640nm ~ 690nm.

In lighting device 7A, the configuration of the 1st light source 50a and the 2nd light source 50b sets according to the configuration of the medium accommodation section 26 in dish for cultivating 3.In the present embodiment, the 1st light source 50a and the 2nd light source 50b is configured accordingly with structure medium accommodation section 26 being configured to row on dish for cultivating 3.Specifically, on a surperficial 52a of substrate 52,18 the 1st light source 50a form a line by the left and right directions along framework 5 with being separated with predetermined distance.On a surperficial 52a of substrate 52,18 the 2nd light source 50b are configured to row with being separated with predetermined distance by the left and right directions along framework 5, and configure two on the width of framework 5, with clipping the row lined up by the 1st light source 50a arrange this by 18 light sources 50 bthe row lined up.The quantity of the 1st light source 50a and the 2nd light source 50b can according to design suitably setting.

(a) of Figure 25 is the figure schematically showing the light that lighting device projects, and (b) of Figure 25 schematically shows by 3 of lighting device light that light source irradiation goes out at the figure cultivating the irradiation area on each horizontal plane (A ~ C) in space.Figure 26 schematically shows by the intensity of light on each horizontal plane (A ~ C) of 3 of lighting device light that light source irradiation goes out in cultivation space or the figure of the value of light quantity.

(a) of Figure 25 be from the sidepiece 42 of framework 5, sidepiece 44 side is observed time figure.In (b) of Figure 25, A represents the irradiation area of the light on the surperficial 20a of the main part 20 (cap 12) of dish for cultivating 3, B represents the irradiation area of the light on the middle aspect MS2 of cultivation space S, and C represents the irradiation area of the light on the middle aspect MS1 of cultivation space S.In fig. 26, the longitudinal axis represents the intensity of light or the value of light quantity, and transverse axis represents each irradiation area (FA1, FA2, FB1, FB2, FC1, FC2) of light on each horizontal plane (A ~ C) that each light source projects.

As shown in (a) of Figure 25, the optical axis of the 1st light source 50a is towards the optical axis of medium accommodation section the 26,2nd light source 50b on the surperficial 20a of the main part 20 of dish for cultivating 3 towards the ad-hoc location on the surperficial 20a of the surrounding except the medium accommodation section 26 on surperficial 20a.Thus, around medium accommodation section 26 and this medium accommodation section 26, the 1st region A1 is created.

In the surperficial 20a of the main part 20 of the cap 12 of dish for cultivating 3, irradiate at the 1st region A1 comprising medium accommodation section 26 light having the light of the blue component of the 1st light source 50a and the red color components of the 2nd light source 50b.That is, the 1st region A1 becomes overlapping by the irradiation area FA1 of the light irradiated from the 1st light source 50a and the irradiation area FA2 of light that irradiates from the 2nd light source 50b and the region of synthesis.

In addition, as shown in (b) of Figure 25, the generation of the irradiation area of each light source is as follows: decline along with towards horizontal plane C, B, A, and the lap of irradiation area is each other expanded, and entirety expands gradually in the horizontal direction on one side.This is because the optical axis of each light source is towards the medium accommodation section 26 of horizontal plane A, the optical axis of the 1st light source 50a towards immediately below the central portion of medium accommodation section 26, the optical axis of the 2nd light source 50b is towards the cause of the ad-hoc location of the surrounding except medium accommodation section 26.Thus, in the surperficial 20a (horizontal plane A) of the main part 20 of the cap 12 of dish for cultivating 3, the light (the 2nd light source 50b) of blue light (the 1st light source 50a) and redness is overlapping at the central portion of the irradiation area FA1 of the 1st region A1, therefore, when plant germination and stem, leaf formation in effective.

Now, as shown in figure 26, the intensity of light comprising the repeating portion in the synthesis region between irradiation area FA1 in the 1st region A1 of the surrounding of medium accommodation section 26 and irradiation area FA2 on the surperficial 20a of main part 20 or the value of light quantity are greater than the 2nd region A2 in the outside of the 1st region A1 and the intensity of light of other each MS1, MS2 or the value of light quantity.Namely, in the surperficial 20a (horizontal plane A) of the main part 20 of the cap 12 of dish for cultivating 3, the intensity of light in the region of the central portion of the irradiation area FA1 of the 1st region A1 or the value of light quantity are greater than the irradiation area FC1 of the middle aspect MS1 of horizontal plane C, the intensity of light in region of central portion of irradiation area FB1 of the middle aspect MS2 of horizontal plane B or the value of light quantity.

As shown in figure 25, in middle aspect MS1 and middle aspect MS2 (horizontal plane B and horizontal plane C), with the main part 20 of the cap 12 of dish for cultivating 3 as horizontal plane A surperficial 20a compared with, the region of the irradiation area FB1 of the light irradiated from the 1st light source 50a and the 2nd light source 50b and the region of irradiation area FB2 overlap, irradiation area FC1 and irradiation area FC2 overlap diminishes.Thus, in middle aspect MS1 and middle aspect MS2 (horizontal plane B and horizontal plane C), for the Ye Eryan stretched laterally from stem in plant, mainly irradiated the effective red light of the growth of leaf by the 2nd light source 50b.

Now, as shown in figure 26, in middle aspect MS1 and middle aspect MS2 (horizontal plane B and horizontal plane C), the intensity of light of irradiation area FB1, irradiation area FB2, irradiation area FC1, irradiation area FC2 or the value of light quantity are less than the intensity of light or the value of light quantity of the repeating portion in the synthesis region between irradiation area FA1 in the 1st region A1 on the surperficial 20a of the main part 20 of the cap 12 of dish for cultivating 3 and irradiation area FA2.In addition, in middle aspect MS1 and middle aspect MS2 (horizontal plane B and horizontal plane C), the intensity of light or the large region of the value of light quantity expand towards left and right horizontal direction.That is, in middle aspect MS1, middle aspect MS2, the range of exposures of light can be expanded, therefore, make the fully shower illumination and facilitate photosynthesis of the leaf that launches in the horizontal direction.As in the surperficial 20a (cultivation basal plane) of undermost main part 20, make the range of exposures centralization of multiple light, increase the intensity of light or the value of light quantity, and when facilitating germination and stem, leaf formation.

Being configured in indoor plant cultivating device 1, in order to promote the growth of plant, preferably realize the environment identical with the situation outside the room be sunlighted.At this, the blue component of the bud of known plant, the growth needs light of stem, and the red color components of the growth needs light of the leaf of plant.Such as, use and the chip of the light emitting diode of redness, green and blue component is used as a light emitting source and obtains the white light-emitting diode of white, or use the lighting device having synthesized the color of blue LED and the color of red light emitting diodes.

But in the white light-emitting diode with said structure, to obtain the blue component or the red color components that are suitable for plant growth, then need to increase light quantity, human eye can feel bright.Therefore, be unsuitable for indoor viewing and admiring, can interior decoration be destroyed.In addition, in the plant cultivating device in the past with blue LED and red light emitting diodes, blue LED to be made luminous period at plant germination, red light emitting diodes will be made luminous at the growth period of leaf.Therefore, the bright light opportunity controlling blue LED and red light emitting diodes is needed, complicated operation.

In the present embodiment, the action effect identical with the 1st embodiment can be played.In addition, in the present embodiment, 2nd light source 50b of the 1st light source 50a in lighting device 7A with the light that can send blue component and the light that can send red color components, the optical axis of the 1st light source 50a mainly towards the optical axis of medium accommodation section the 26,2nd light source 50b of dish for cultivating 3 mainly towards the region (ad-hoc location except medium accommodation section 26 on surperficial 20a) outside the medium accommodation section 26 in surperficial 20a.Thus, in plant cultivating device 1, at the light that can irradiate blue component and red color components period with high strength to plant that germinates, when plant growth exhibition leaf, the light of red color components mainly can be irradiated to leaf.Therefore, Promoting plant growth can be sought.

(a) of Figure 30 is the figure schematically showing the light that lighting device projects, and (b) of Figure 30 schematically shows by 3 of lighting device light that light source irradiation goes out at the figure cultivating the irradiation area on each horizontal plane (A ~ C) in space.Figure 31 is the figure schematically showing the intensity of light on the light that irradiated by the lighting device each horizontal plane (A ~ C) in cultivation space or the value of light quantity.

In (b) of Figure 30, A represents the irradiation area of the light on the surperficial 20a of the main part 20 (cap 12) of dish for cultivating 3, B represents the irradiation area of the light on the middle aspect MS2 of cultivation space S, and C represents the irradiation area of the light on the middle aspect MS1 of cultivation space S.In Figure 31, the longitudinal axis represents the intensity of light or the value of light quantity, and transverse axis represents each irradiation area (FA1, FA2, FB1, FB2, FC1, FC2) on each horizontal plane (A ~ C).

As shown in (a) of Figure 30, the optical axis of the 1st light source 50a and the 2nd light source 50b is towards the central part of the medium accommodation section 26 on the surperficial 20a of the main part 20 of dish for cultivating 3.Thus, around medium accommodation section 26 and this medium accommodation section 26, the 1st region A1 is created.Namely, the optical axis of each light source is all towards the medium accommodation section 26 of horizontal plane A, the optical axis of the 1st light source 50a towards immediately below the central portion of medium accommodation section 26, the optical axis of the 2nd light source 50b is towards the central portion of medium accommodation section 26, and the position of the point that each optical axis is intersected in horizontal plane A is roughly consistent.
