Description

The present invention relates to an artificial cultivation device. In particular, the present invention relates to an artificial cultivation device in which the arrangement of LED lighting equipment for artificial lighting is devised. The artificially cultivated plants are not particularly limited.

In recent years, instead of the traditional traditional farming method that uses natural light from the outside world, artificial cultivation technology for plants that grows plants indoors using artificial lighting has attracted attention. In artificial cultivation, it has become possible to control the flowering and promote the growth of plants by irradiating light with a suitable wavelength such as blue, red, and far red according to the plant species.
As a light source for artificial lighting, the development of high-power LED elements (light emitting diode elements) has progressed in recent years, and so-called LED lighting fixtures have begun to be used in place of conventional white light bulb lighting and fluorescent lighting. In particular, the white LED element is suitable as artificial lighting for artificial plant cultivation equipment because it can emit light of many wavelengths, and also has the characteristics of small size, power saving, and long life of the LED element. Coupled with this, the spread is gaining momentum. Further, since the LED elements have relatively uniform wavelengths of light emitted and generate a relatively small amount of heat, it has been proposed to use an artificial lighting device in which a large number of LED elements are arranged as a lighting device for artificial cultivation.

In the prior art, there is one proposed as an artificial cultivation device using an LED lighting device in which a large number of LED elements are arranged.
As shown in FIG. 15, the plant cultivation apparatus disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 2013-17397) has a cultivation rack 3 having a mounting shelf 4 on which the cultivation tank 2 is placed and an upper portion of the mounting shelf 4. It is provided with LED illuminators 5 arranged at intervals. The structure of the cultivation rack 3 is such that a large number of vertical columns 8 are arranged, the vertical columns 8 are connected by horizontal members 9 to connect the vertical columns 8 side by side to form a single vertical frame 7, and a pair of left and right vertical frames 7A7B are bridged to each other. The cultivation rack 3 is formed by bridging with the connecting member 18. A large number of support portions 6 protruding from the side surfaces of the vertical columns 8 of the vertical frame 7 are projected, and the LED illuminator 5 is attached to the support portions 6. As shown in step 0028 of the same publication, it is disclosed that the LED illuminator 5 is fixed to the vertical column 8 by screwing, riveting, or the like to the receiving portion 32 of the support portion 6.

Further, in the plant cultivation apparatus disclosed in Patent Document 2 (Japanese Unexamined Patent Publication No. 2015-006162), as shown in FIG. 16, the LED lighting device 5 is arranged in the cultivation rack, and the LED lighting device 5 has a frame. A plate 15 shaped like a frame, a plurality of LED lamps 16 detachably attached to the frame 15, and a plate detachably attached to the frame 15 so as to be located above the LED lamp 16 and having a reflective surface facing downward. The shape reflecting member 17 is provided.
The left and right ends of the LED lamp 16 are fitted into the notch 23 of the lamp receiving portion 21 of the left and right frame members 18 of the horizontal frame 15, and are fixed by the holding member 25 detachably attached to the horizontal frame 15. ing. The LED lamp 16 is fixed by screwing the left and right ends of the LED lamp 16 from above by the pressing member 25 via the elastic member 29.

In this way, in both Patent Document 1 and Patent Document 2, a structure called a cultivation rack is assembled, and the end of the LED luminaire is placed in a predetermined position on the cultivation rack, and then screwed, riveted, etc. By fixing with a rivet, it is arranged in a predetermined position to create a stable state.

Japanese Unexamined Patent Publication No. 2013-017397

One of the problems with the conventional LED luminaire is the cost and load of the electrical work in the cultivation rack of each LED luminaire.
The number of LED lighting fixtures arranged in the unit of the artificial cultivation device is large, and in a large-scale plant factory, many units of the artificial cultivation device are installed, and each LED lighting is installed. The amount of electrical wiring work for tools becomes enormous. As a result, there is a problem that the installation cost of the artificial cultivation equipment unit and the construction cost of the plant factory are high. It is feared that this problem will be a major obstacle to the spread of artificial cultivation equipment in plant factories in the future.

In the case of the plant cultivation apparatus disclosed in Patent Document 1, it is necessary to attach LED illuminators to a large number of support portions 6 provided on the side surfaces of the vertical columns 8 of the vertical frame 7. As shown in step 0028 of the same publication, it is necessary to fix the LED luminaire 5 to the vertical support 8 by screwing, rivet fixing, etc. to the receiving portion 32 of the support portion 6, and then perform the electrical wiring work. A considerable amount of workers' installation work and electrical wiring work are required for this one LED luminaire 5, and the work of installing an extremely large number of LED luminaires 5 in a complicated manner and performing the electrical wiring work is both a construction period and a cost. It will be huge.
In the plant cultivation device of Patent Document 1, even when the LED lighting tool 5 is not screwed or riveted to the receiving portion 32 of the support portion 6, each LED lighting is applied to a long cultivation rack. It is necessary to manually place the tool 5 and perform electrical wiring work.

Even in the plant cultivation apparatus disclosed in Patent Document 2, as shown in FIG. 16, when arranging the straight tube type LED lamp 16 on the cultivation rack, the left and right ends of the straight tube LED lamp 16 are placed on both the left and right frames of the horizontal frame 15. The straight tube type LED lamp 16 is fitted into the notch 23 of the lamp receiving portion 21 of the member 18, and the left and right ends of the LED lamp 16 are screwed from above by the pressing member 25 via the elastic member 29. It is necessary to fix it and perform electrical wiring work. After all, a considerable amount of work is required for each LED luminaire 5, and the work of installing an extremely large number of LED luminaires 5 in a complicated manner and performing electrical wiring work is enormous in terms of time and cost. turn into.
Similarly in Patent Document 2, even when the straight tube type LED lamp 16 is screwed from above by the pressing member 25 and not riveted, each LED lamp 5 is manually attached to a long cultivation rack. After careful placement, complex electrical work needs to be done.

In view of the above problems, the present invention reduces the work of arranging LED luminaires at predetermined locations and the work of electrical wiring on a structure such as a rack as in the conventional case, and reduces the work of installing artificially cultivated plant shelves and the cost. It is an object of the present invention to provide a squeezed artificial cultivation device.

In order to achieve the above object, the artificial cultivation device of the present invention includes an artificially cultivated plant shelf for storing artificially cultivated plants, a first connection portion, a second connection portion, the first connection portion, and the above. An electronic board passed between the second connection portions, an LED line light source in which a large number of LED chips are attached to the electronic board, and the first connection portion and the second connection portion are passed so as to pass between the first connection portion and the second connection portion. A crossover voltage supply line for supplying a power supply voltage, an LED lighting fixture provided with a connection line or a voltage control circuit for supplying power from the crossover voltage supply line to the LED line light source, and facing the artificially cultivated plant shelf. The first of the plurality of LED lighting fixtures in which a support for supporting the LED lighting fixture is provided, a plurality of the LED lighting fixtures are arranged on the artificially cultivated plant shelf, and the crossing voltage supply line is arranged. It is an artificial cultivation apparatus characterized by having a connection structure capable of connecting different kinds or the same kind to each other so as to be able to energize the connection part of the above and the second connection part.
With the above configuration, in the work of arranging the LED luminaire on the artificially cultivated plant shelf, after the LED luminaire is supported at a predetermined position via the support, the electrical wiring is easily connected via the cross voltage supply line. be able to.
Conventionally, it was necessary to connect to a socket and perform wiring work inside and outside the artificial cultivation device from the inside of the socket to an external commercial power source. It is unnecessary, and complicated electrical wiring work is not required by directly connecting the connection portions.

Here, there can be two ways of arranging the LED luminaires and the structure of the crossover voltage supply line.
The first structural pattern is a type in which LED illuminators are connected in series. If the LED illuminator is a straight tube type LED illuminator, the connection direction between the LED illuminators is the length direction of the LED illuminator. The crossover voltage supply line passes the power supplied through the first connection portion through the inside of the same LED luminaire to the opposite second connection portion, and the adjacent LED via the second connection portion. It is a first crossover voltage supply line that passes to the first connection portion of the luminaire.
The first structural pattern connects the LED luminaires in series, and inserts and connects the first connection portion of the subsequent LED luminaire to the second connection portion of the adjacent LED luminaire. By doing so, it becomes a structure in which a plurality of LED luminaires are connected in series in order. Electrically, from the first connection portion at one end of the LED luminaire, through the first crossover voltage supply line penetrating the inside, to the second connection portion at the other end, and from the second connection portion. Further, it is connected to the adjacent first connecting portion.
For example, as a connection structure between the first connection portion and the second connection portion connected in series, one is a base provided with a metal insertion pin, and the other is a base provided with a metal pinhole. Therefore, there is a structure in which the first connecting portion and the second connecting portion are fitted to each other so that they can be energized at the portion where the connection is applied. It is preferable that the fitting portion between the two has a waterproof structure.
Further, for example, there may be a structure using an interstitial body interspersed between the first connecting portion and the second connecting portion connected in series. As the shape of the intercalating body, for example, one surface is fitted with the first connecting portion, the other surface is fitted with the second connecting portion, and the first connecting portion is formed. The shape is such that the second connecting portions can be connected so as to be energized.

In the first structural pattern of the present invention, as described above, the external voltage supply line- (the first connection portion of the first-stage LED lighting fixture-the first crossing voltage supply line-the second connection portion). )-(First connection part of the LED lighting fixture in the next stage-First crossing voltage supply line-Second connection part)-... Inside the LED illuminator, a voltage is drawn in parallel from the first crossing voltage supply line via a connection line or a voltage control circuit and supplied to each LED line light source. In other words, each LED luminaire has a ladder-type connection that serves as a ladder ladder when the voltage supply line is regarded as a ladder support.

Here, the connection line includes a type in which there is no particular electronic component and only the wiring of the lead-in wire, and there may be a type in which a small number of electronic components such as a capacitor are incorporated. In the case of the artificial cultivation apparatus of the present invention, there are many cases where a slight voltage fluctuation that does not damage the LED element does not pose a problem in actual operation, and in that case, only a lead-in wire is sufficient.

The voltage control circuit may include an electronic circuit having a voltage stabilizing function. If the external commercial power supply is unstable, each LED luminaire may be provided with a stabilization function by a voltage control circuit, but at the point where the external commercial power supply is pulled into the building of the artificial cultivation device. In some cases, it can be dealt with by providing a voltage stabilizer collectively.

The support has a recessed shape that abuts on the outer surface of the LED luminaire or a recessed shape that abuts at least two points on the outer surface. In this first structural pattern, the length direction of the artificially cultivated plant shelf A recessed cross section may be provided perpendicular to the axis of. That is, LED luminaires can be connected in series in the length direction of the artificially cultivated plant shelf.

In the case of a general LED luminaire, if, for example, 200 V is supplied between the first base and the second base attached to the external socket, and the internal LED line light source has 90 elements. Theoretically, a voltage of about 3V is supplied to each element.
On the other hand, in the first structural pattern of the present invention, the first connection portion at the head of the subsequent LED illuminator is inserted into the second connection portion at the tail of the preceding LED illuminator in order. Since they are connected, they are different in that the voltage is not supplied from the external socket to each base as in the conventional case.

The voltage of the trademark power supply varies depending on the type of contracted power, country, and region, but it may be designed according to the voltage supplied to the LED line light source and the number of LED elements.
The power supply voltage supplied from the outside supplied to the LED line light source will be described. The power supply voltage is not particularly limited in the present invention, and various power supplies can be applied. It may be a constant voltage source or a constant current source. In general, a constant voltage source often has a simpler circuit configuration. When the constant voltage source is used, a commercial power source transformed from the outside to a predetermined voltage (for example, 200 V) by a transformer may be supplied. A switching power supply may be applied to obtain a uniform voltage, but the circuit configuration becomes complicated. Since the present invention is an artificial cultivation device, there are many cases where small fluctuations in voltage do not pose a problem, and in many cases, adjusting the transformer of a commercial power source is sufficient. It can also be applied to a voltage source such as PCT / JP2018 / 013206, which the patent applicant has filed in advance.

The second structural pattern of the present invention connects the LED luminaires in parallel, connects the first connection portions of the adjacent LED luminaires by the second crossing voltage supply line, and also connects the first connection portions of the adjacent LED luminaires. By connecting the second connection portions to each other and connecting a plurality of LED illuminators in parallel, each LED line light source is connected in a ladder shape. For example, each LED line light source is connected in parallel to the second crossover voltage supply line via a connection line or a voltage control circuit.
For example, the support has a recessed shape that abuts on the outer surface of the LED illuminator or a recessed shape that abuts at least two points on the outer surface, and is recessed with respect to the axis in the length direction of the artificially cultivated plant shelf. It is possible that a plurality of cross sections of the shape are provided in parallel in the horizontal direction.

If the voltage supplied to the second crossover voltage supply line of the second structural pattern of the present invention is 200 V, each LED illuminator is connected in parallel to the second crossover voltage supply line. Therefore, it may be designed so that 200 V is supplied to the LED line light source inside each LED illuminator and a voltage of about 3 V is applied to each LED element.

As the artificial cultivation device, the artificially cultivated plant shelf can be configured in multiple stages. In order to make effective use of the space in the factory building, it is necessary to increase the installation area of artificially cultivated plant shelves per floor area, but since artificial lighting is used in the artificial cultivation equipment, a multi-stage configuration is possible.

According to the artificial cultivation apparatus of the present invention, in the work of arranging the LED lighting equipment on the artificially cultivated plant shelf, after the LED lighting equipment is supported at a predetermined position via the support, the electrical wiring is connected to the crossing voltage supply line. It is possible to provide an artificial cultivation device that can be easily connected via a device, reduces the arrangement work and electrical wiring work of LED luminaires at predetermined locations, installs artificially cultivated plant shelves, and reduces costs. ..

In the configuration example of the first embodiment, by providing the first crossover voltage supply line 126-1, the LED illuminator 120 is energized from the first base 122 to the second base 123.

In this way, by connecting a plurality of LED illuminators 120 having the configuration according to the first embodiment in series, the external voltage supply line-the first base 122 of the first stage LED illuminator 120-the first crossing Voltage supply line 126-1-Second base 123-First base 122 of the second stage LED lighting fixture-First crossing voltage supply line 126-1-Second base 123-... and so on. A single voltage supply path is secured, and inside each LED illuminator 120, a voltage is drawn in parallel from the first crossing voltage supply line 126-1 via a connection line or a voltage control circuit 127, and each of them. It is supplied to the LED line light source 125 of each stage of. In other words, if the voltage supply line is regarded as a ladder support, each LED luminaire has a ladder shape that serves as a ladder ladder.
For example, when 200V is supplied from an external voltage supply line, 200V is applied to the LED line light source 125 inside each LED illuminator 120 connected in series, and about 3V is applied to each LED element. Voltage is supplied. If the contracted power differs or the commercial voltage differs depending on the country or region, the design may be performed in consideration of the supplied voltage and the number of LEDs of the LED line light source 125.

The connection line or voltage control circuit 127 is a circuit that controls the power supply from the first crossover voltage supply line 126-1 to the LED line light source 125. The simplest configuration is a power lead-in connection line from the first crossover voltage supply line 126-1 to the LED line light source 125. It is possible to provide a capacitor to prevent voltage fluctuations, a voltage stabilization circuit, etc., but the voltage given to the first crossing voltage supply line 126-1 from the outside is the LED line as the artificial cultivation device 100. As long as the light source 125 is within the permissible range, it is assumed that a power lead-in wire is often sufficient because voltage control with higher accuracy is not required. In this example, the connecting line 127 is connected to the LED line light source 125 on the surface side of the electronic substrate 124 via a through hole.

Next, the support 140 will be described. The support 140 is a member that supports the LED illuminator 120.
The shape and structure of the support 140 are not limited, but the LED illuminator 120 has a recessed shape along a part of the outer surface of the LED illuminator 120 or a recessed shape that abuts at least two points on the outer surface, and the LED illuminator 120 can be stably mounted. Anything that can be placed or locked will do. In this example, since the LED illuminator 120 is a straight tube type LED illuminator with a straight tube member 121, the shape of the support 140 is a circle having a shape corresponding to the outer diameter of the straight tube member 121 of the LED illuminator 120. The arc-shaped recessed shape 141 or the V-shaped recessed shape 142 supports the outer surface of the LED illuminator 120 at two points. If the straight tube member 121 has a shape different from that of a cylinder, or if the straight tube member 121 itself is not provided, the support 140 has any shape of the outer shape of the straight tube type LED illuminator 120. Any shape may be used as long as it can be stably supported along a part of.

5 and 6 are views showing an example of a cross-sectional shape of a shape example of the support 140. It is attached to the bottom surface of the horizontal plate frame 113 or the container portion 114 of each of the artificially cultivated plant shelves 110 having a multi-stage structure, and supports the LED illuminator 120.
FIG. 5 shows a type having an arcuate recess shape 141 having a shape corresponding to the outer diameter of the LED illuminator 120. The support 140 hangs down from the bottom surface of each of the artificially cultivated plant shelves 110 having a multi-stage structure, and an arcuate recess shape 141 is provided on the inner surface thereof. The inner diameter of the arc-shaped recessed shape 141 corresponds to the outer diameter of the LED illuminator 120, and if the LED illuminator 120 is placed and locked, the LED illuminator 120 can be stably supported.
FIG. 6 shows a V-shaped recessed shape 142 in which the outer surface of the LED illuminator 120 is supported at two points. The support 140 hangs down from the bottom surface of each of the artificially cultivated plant shelves 110 having a multi-stage structure, and a V-shaped recessed shape 142 is provided on the inner surface thereof. The V-shaped recessed shape 142 has a size and an angle on which the LED illuminator 120 can be placed, and if the LED illuminator 120 is placed and locked, the LED illuminator 120 can be stably supported.

There may be various variations in the arrangement direction, length, and number of the supports 140.
The arrangement direction of the support 140 is related to the first structural pattern in which the LED illuminators 120 are connected in series in this example, and therefore, with respect to the axis in the length direction of the artificially cultivated plant shelf 110. The cross section of the recessed shape 141 or the recessed shape 142 of the support 140 is provided vertically. In this arrangement direction, if the LED illuminator 120 fits in the recessed shape 141 or the recessed shape 142 of the support 140, the length direction of the LED illuminator 120 coincides with the length direction of the artificially cultivated plant shelf 110.
In the first embodiment, it is sufficient that the LED luminaires 120 are electrically connected in series, and the LED luminaires 120 do not necessarily have to be arranged in a straight line as a mechanical arrangement, and the LED luminaires 120 do not necessarily have to be arranged in a straight line. It may be bent or angled relative to each other.

When the length of the support 140 is short, it is shorter than the length of the LED illuminator 120. For example, the support 140 is located at a ratio of several to one LED illuminator 120. Some are provided at a distance. In the example shown in FIG. 2, three supports 140 are arranged at intervals with respect to one LED illuminator 120.
When the length of the support 140 is long, only one is attached to each artificially cultivated plant shelf 110 in a multi-stage structure, and the length corresponding to the length of the artificially cultivated plant shelf 110, that is, artificially cultivated. A support 140 is provided over the entire length of the plant shelf 110. However, in this case, since the support 140 is present on the entire lower surface of the LED illuminator 120 to be arranged, if the support 140 is opaque, the illumination light of the LED illuminator 120 is blocked, so that the support 140 is used. It is necessary to use a translucent material.

Next, a method of attaching the LED illuminator 120 to the support 140 will be described.
There are at least two patterns in the arrangement direction of the support 140 and the mounting method of the LED illuminator 120.
The first mounting method is a method of mounting the LED illuminator 120 from the side of each support 140.
As shown in FIGS. 5 and 6, the support 140 has a kind of hook shape provided with a partially released portion on the side, and the LED illuminator 120 can be inserted from the side. it can. Therefore, the first mounting method is a mounting method in which the LED luminaires 120 are sequentially inserted from the side of the support 140 and the LED luminaires 120 are connected in order.
As shown in FIG. 7, the LED luminaire 120 is inserted from the side of the support 140, placed and locked, and with respect to the second base 123 at the rear end of the preceding LED illuminator 120. The first base 122 at the tip of the subsequent step may be fitted and connected as shown in FIG. 3, and the LED illuminator 120 may be connected in series in the length direction thereof. As a result, the LED illuminator 120 can be accommodated in a predetermined position of the arc-shaped recess 141 or the V-shaped recess 142.

In the second mounting method, the LED luminaire 120 is pushed in from the front direction of the support 140 from the length direction, and the LED luminaire 120 is slid in the support 140 and is mounted one after another through the support 140. The method.
FIG. 8 is a diagram showing a state in which the LED illuminator 120 is inserted into the support 140 in order from the length direction, pushed in while being supported, moved, and arranged one after another as the second mounting method. is there.
As shown in FIG. 8, if the LED illuminator 120 is pushed in while being connected one after another from the front direction of the support 140 (from the left end to the right in FIG. 8), it slides through the inside of the support 140. When it finally reaches a predetermined position, it can be accommodated in the arc-shaped recessed shape 141 or the V-shaped recessed shape 142.
Here, in the attachment of the LED illuminator 120 to the support 140, the attachment state is stabilized by connecting the first base 122 and the second base 123 between the adjacent LED illuminators 120. ..

As shown in FIG. 8, it can be seen that the moving direction of the LED illuminator 120 is the length direction of the LED illuminator 120. A group of LED illuminators 120 in which a plurality of LED illuminators 120 are connected in series and integrated are pushed and moved so as to straddle each support 140.

As shown in FIG. 8, during the installation work, the worker fits and connects the subsequent first base 122 to the second base 123 at the rear end of the preceding LED luminaire 120 to integrate them. As shown in FIG. 3, the LED luminaire 120 is pushed in as a group, and the metal insertion pin 1221 of the first base 122 of the LED luminaire 120 is pushed in first. While inserting it into the metal pinhole 1231 of the base 123 of 2, the first base 122 and the second base 123 may be fitted and mechanically connected, and then pushed in.
With only such a simple installation work, it is possible to complete the installation work of a predetermined number of LED luminaires 120 at a predetermined position and further the electrical wiring work.

It is also possible to provide a stopper at the end of the artificial cultivation shelf 110 so that the preceding LED illuminator 120 does not fall off. When the LED illuminator 120 is pushed in from one end, it can be prevented from inadvertently moving to the other end and falling off from the other end.

FIG. 9 is a diagram briefly showing an electrical connection configuration of the LED illuminator 120 according to the first embodiment. As shown in the mounting example shown in FIG. 9A, the first base 122 and the second base 123, which are mechanically adjacent to each other in series, are connected to each other, and the crossover voltage inside the LED illuminator 120 is connected to each other. When energized by the supply line, it is also electrically connected as shown in FIG. 9B.
As shown in FIG. 9A, a plurality of LED illuminators 120 arranged on the guide rail by connecting the first base 122 and the second base 123 are lined up in series, as shown in FIG. 9B. The first crossover voltage supply line 126-1 is also connected in series, and the voltage is drawn in parallel from the first crossover voltage supply line 126-1 by the connecting line 127, which is a lead-in line, to the LED line light source 125. It can be energized.

As a specific example, as shown in FIG. 3, the electrical connection structure between the first base 122 and the second base 123 is such that one is a metal insertion pin 1221 and the other is a metal pin hole 1231. There is, and by fitting the two, they are connected so that they can be energized at the point where they are connected, and the supply voltage from the outside passes through the internal first crossing voltage supply line 126-1 and sequentially to the LED illuminator 120 in the next stage. 200V is evenly applied to each LED illuminator 120, drawn into the internal LED line light source 125, and a voltage of about 3V is applied to each LED element.

Here, the power source for the electric power supplied from the outside to the first crossover voltage supply line 126-1 is not particularly limited in the present invention, and various power sources can be applied. It may be a constant voltage source or a constant current source. In general, a constant voltage source often has a simpler circuit configuration. When the constant voltage source is used, a commercial power source adjusted to a predetermined voltage (for example, 200 V) may be supplied from the outside. A switching power supply may be applied to obtain a uniform voltage, but the circuit configuration becomes complicated. Since the present invention is an artificial cultivation device 100, there are many cases where small voltage fluctuations do not matter, and if the external commercial power supply is 200V, it can be used as it is, and if the external commercial power supply is 100V, the step-up adjustment of the transformer is adjusted. In many cases, 200V is sufficient. It can also be applied to a voltage source such as PCT / JP2018 / 013206, which the present inventor has previously applied for.
