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 devices for artificial lighting is devised. The plant to be artificially cultivated is not particularly limited.

2. Description of the Related Art In recent years, artificial cultivation techniques for plants that grow plants using artificial lighting indoors, instead of the traditional traditional farming method using natural light from the outside world, have attracted attention. In artificial cultivation, it is becoming possible to control flowering and promote growth of plants by irradiating light of a suitable wavelength, such as blue, red, or far red, depending on the plant species.
As a light source for artificial lighting, in recent years, the development of high-output LED elements (light-emitting diode elements) has been progressing, and so-called LED illuminators have begun to be used in place of conventional white light bulb illumination and fluorescent lamp illumination. In particular, a white LED element can emit light of many wavelengths, so that it is suitable as artificial lighting for an artificial plant cultivation device. In addition, the LED element has the characteristics of small size, power saving, and long life. Together, the spread is gaining momentum. In addition, since the LED elements emit light of relatively uniform wavelengths and generate relatively little 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 related art, there has been proposed an artificial cultivation device using an LED lighting device in which a large number of LED elements are arranged.
As shown in FIG. 15, a plant cultivation apparatus disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2013-17397) has a cultivation rack 3 having a mounting shelf 4 on which a cultivation tank 2 is mounted, and a cultivation rack 3 above the mounting shelf 4. And an LED lighting device 5 arranged at an interval. The structure of the cultivation rack 3 is such that a large number of vertical supports 8 are arranged, and the vertical supports 8 are connected by horizontal members 9 connecting the horizontal to each other to form a single vertical frame 7, and a pair of left and right vertical frames 7A7B is bridged. The cultivation rack 3 is formed by bridging with the connecting member 18. A large number of supporting portions 6 projecting from the side surfaces of the vertical columns 8 of the vertical frame 7 are projected, and the LED lighting device 5 is attached to the supporting portions 6. As disclosed in the publication at column 0028, it is disclosed that the LED lighting device 5 is fixed to the vertical support 8 by screwing, riveting, or the like to the receiving portion 32 of the support portion 6.

Further, in the plant cultivation device disclosed in Patent Document 2 (Japanese Patent Application Laid-Open No. 2015-006162), as shown in FIG. 16, an LED lighting device 5 is arranged on a cultivation rack, and the LED lighting device 5 has a frame. -Shaped frame 15, a plurality of LED lamps 16 detachably attached to frame 15, and a plate detachably attached to frame 15 so as to be located above LED lamp 16, and having a reflection surface facing downward A reflection member 17 is provided.
The left and right ends of the LED lamp 16 are fitted into the notches 23 of the lamp receiving portions 21 of the left and right frame members 18 of the horizontal frame 15, and are fixed by a holding member 25 detachably attached to the horizontal frame 15. ing. Then, the left and right ends of the LED lamp 16 are screwed from above by a pressing member 25 via an elastic member 29, whereby the LED lamp 16 is fixed.

As described above, in both Patent Literature 1 and Patent Literature 2, a structure called a cultivation rack is assembled, and the cultivation rack is screwed, riveted, etc. after placing the end of the LED lighting device at a predetermined position.

JP 2013-017397 A JP A 2015-006165 A

One of the problems in the conventional LED lighting device is the cost and load of the electric work in the cultivation rack for each LED lighting device.
The number of LED lighting devices provided in the unit of the artificial cultivation apparatus is large, and in the case of a large-scale plant factory, a large number of units of the artificial cultivation apparatus are installed. The amount of electric wiring work for the fixture becomes enormous. As a result, there is a problem that the installation cost of the artificial cultivation device unit and the construction cost of the plant factory increase. It is feared that this problem will greatly hinder the spread of artificial cultivation equipment in plant factories in the future.

In the case of the plant cultivation apparatus disclosed in Patent Literature 1, it is necessary to attach an LED lighting device to a large number of supports 6 provided on the side surfaces of the vertical columns 8 of the vertical frame 7. As shown in the column 0028 of the publication, it is necessary to fix the LED lighting fixture 5 to the vertical support 8 by screwing or riveting to the receiving part 32 of the support part 6, and then to perform electric wiring work. The installation work of a considerable number of workers and the electric wiring work are required for one LED lighting device 5, and the work of performing the electric wiring work by mounting an extremely large number of LED lighting devices 5 in a complicated manner requires both a work period and cost. It will be huge.
In the plant cultivation apparatus of Patent Literature 1, even if the LED lighting device 5 is not screwed or riveted to the receiving portion 32 of the support portion 6, one LED lighting device for a long cultivation rack is used. It is necessary to place the tool 5 by hand and perform electrical wiring work.

In the plant cultivation apparatus disclosed in Patent Document 2, as shown in FIG. 16, when arranging the straight tube LED lamps 16 on the cultivation rack, the left and right ends of the straight tube LED lamps 16 are arranged on both the left and right frames of the horizontal frame 15. The 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 with a holding member 25 via an elastic member 29, so that the straight tube LED lamp 16 is obtained. It is necessary to fix and perform electrical wiring work. Again, each LED lighting device 5 requires a considerable amount of work by a worker, and the work of installing an extremely large number of LED lighting devices 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 lighting device 16 is screwed from above with the pressing member 25 and rivets are not used, each LED lighting device 5 is manually applied to a long cultivation rack. After careful placement, complicated electrical work must be performed.

In view of the above problems, the present invention reduces the work of arranging LED lighting fixtures and electrical wiring work at predetermined locations on a structure such as a rack as in the past, and reduces the work of installing artificially cultivated plant shelves and costs. It is an object of the present invention to provide an artificial cultivation device that has been made to work.

In order to achieve the above object, the artificial cultivation apparatus of the present invention includes an artificial cultivation plant shelf that stores plants to be artificially cultivated, a first connection portion, a second connection portion, the first connection portion, and the first connection portion. An electronic board passed between the second connecting portions, an LED line light source having a large number of LED chips attached to the electronic board, and passing between the first connecting portion and the second connecting portion. A crossover voltage supply line for supplying a power supply voltage, a connection line for supplying power from the crossover voltage supply line to the LED line light source or an LED lighting device including a voltage control circuit, and facing the artificially cultivated plant shelf. A support for supporting the LED lighting device, a plurality of the LED lighting devices are arranged on the artificial cultivation plant shelf, and the crossover voltage supply line is the first of the plurality of LED lighting devices arranged. Connection part and the second connection part An artificial cultivation apparatus characterized by comprising a connection structure that can be connected to be energized heterogeneous or between homologous to each other.
According to the above configuration, in the operation of arranging the LED lighting device on the artificially cultivated plant shelf, after supporting the LED lighting device at a predetermined position via the support, the electric wiring is easily connected via the crossover voltage supply line. be able to.
Conventionally, connection to the socket and wiring work inside and outside the artificial cultivation device from the inside of the socket to the external commercial power supply were necessary. However, in the artificial cultivation device of the present invention, the conventional sockets for each LED lighting device are: It is unnecessary, and complicated electrical wiring work is not required by directly connecting the connection parts.

Here, the arrangement direction of the LED lighting fixtures and the structure of the crossover voltage supply line can be of two types.
The first structure pattern is of a type in which LED lighting fixtures are connected in series. If the LED lighting device is a straight tube LED lighting device, the connection direction between the LED lighting devices is the length direction of the LED lighting device. The crossover voltage supply line transfers the power supplied through the first connection portion to the opposing second connection portion through the inside of the same LED lighting device, and the adjacent LED through the second connection portion. It is a 1st transition voltage supply line which transfers to the 1st connection part of a lighting fixture.
The first structure pattern connects the LED lighting devices in series, and inserts and connects the first connection portion of the subsequent LED lighting device to the second connection portion of the adjacent LED lighting device. By doing so, a structure is obtained in which a plurality of LED lighting fixtures are connected in series one after another. Electrically, from the first connection portion at one end of the LED lighting device to the second connection portion at the other end through a first transition voltage supply line passing through the inside, and from the second connection portion. Further, it is connected to the adjacent first connection part.
For example, as a connection structure between the first connection part and the second connection part connected in series, one base is provided with a metal insertion pin, and the other is provided with a metal pinhole. There is a structure in which the first connection portion and the second connection portion are connected to each other so as to be able to conduct electricity at a portion to be connected by fitting. In addition, it is preferable that the fitting part of both has a structure provided with waterproofness.
Further, for example, there may be a structure using an interposed body inserted between the first connection part and the second connection part connected in series. As the shape of the interposed body, for example, one surface has a shape that fits with the first connection portion, and the other surface has a shape that fits with the second connection portion. The second connection portion is shaped so that it can be electrically connected to the second connection portion.

In the first structure 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 transition voltage supply line-the second connection portion) )-(First connection portion of LED lighting fixture of next stage-first transition voltage supply line-second connection portion)- Inside the LED lighting fixture, a voltage is drawn in parallel from the first transition voltage supply line via a connection line or a voltage control circuit, and supplied to each LED line light source. That is, when the voltage supply line is regarded as a ladder support, each LED lighting device has a ladder-type connection such that it becomes a ladder step.

接続 Here, the connection line includes a type having no electronic component and only a lead-in line, and 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, a slight voltage fluctuation that does not damage the LED element does not often cause a problem in actual operation, and in that case, a simple lead-in line is sufficient.

The voltage control circuit may include an electronic circuit having a voltage stabilizing function. When the external commercial power supply is unstable, a stabilizing function may be provided for each of the LED lighting fixtures by a voltage control circuit. However, at the place where the external commercial power supply is drawn into the building of the artificial cultivation apparatus. In some cases, it is possible to cope with this problem by providing a voltage stabilizing device.

The support has a concave shape in contact with the outer surface of the LED lighting device or a concave shape in contact with at least two points on the outer surface. In the first structural pattern, the length direction of the artificially cultivated plant shelf is May be provided such that the cross section of the hollow shape is provided perpendicular to the axis. That is, LED lighting fixtures can be connected in series in the length direction of the artificially cultivated plant shelf.

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

The voltage of the trademark power supply varies depending on the type of contract power, country and region, but may be designed according to the voltage supplied to the LED line light source and the number of LED elements.
An external power supply voltage 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. A constant voltage source or a constant current source may be used. Generally, the circuit configuration of the constant voltage source is often simpler. In the case of using a constant voltage source, a source obtained by transforming a commercial power supply to a predetermined voltage (for example, 200 V) by a transformer from the outside may be used. Note that a circuit that obtains a uniform voltage by applying a switching power supply may be used, but the circuit configuration becomes complicated. Since the present invention is an artificial cultivation device, small voltage fluctuations do not often cause a problem, and in many cases, the adjustment of the transformer of the commercial power supply is sufficient. Further, a voltage source such as PCT / JP2018 / 013206 filed by the present applicant in advance is also applicable.

The second structure pattern of the present invention is for connecting the LED lighting devices in parallel, connecting the first connection portions of the adjacent LED lighting devices by a second crossover voltage supply line, By connecting the second connection portions and connecting a plurality of LED lighting fixtures in parallel, each LED line light source is connected in a ladder shape. For example, the configuration is such that each LED line light source is connected in parallel to a second transition voltage supply line via a connection line or a voltage control circuit.
For example, the support has a concave shape in contact with the outer surface of the LED lighting device or a concave shape in contact with at least two points on the outer surface, and has a concave with respect to the longitudinal axis of the artificially cultivated plant shelf. A plurality of cross sections of the shape may be provided in parallel in the horizontal direction.

If the voltage supplied to the second transition voltage supply line of the second structure pattern of the present invention is 200 V, each LED lighting device is connected in parallel to the second transition voltage supply line. Therefore, the design may be such that 200 V is supplied to the LED line light source inside each LED lighting device, and a voltage of about 3 V is applied to each LED element.

As an artificial cultivation device, an artificially cultivated plant shelf can have a multi-stage configuration. In order to effectively use the space of the factory building, it is necessary to increase the installation area of the artificially cultivated plant shelf per floor area. However, since the artificially cultivated apparatus uses artificial illumination, a multi-stage configuration is possible.

According to the artificial cultivation device of the present invention, in the work of arranging the LED illuminator on the artificially cultivated plant shelf, after supporting the LED illuminator at a predetermined position via the support, the electric wiring connects the crossing voltage supply line. It is possible to provide an artificial cultivation apparatus that can be easily connected via the LED illuminator, reduces the work of arranging the LED lighting device at a predetermined location and the work of electrical wiring, and reduces the work of installing the artificial cultivation plant shelf and the cost. .

As described above, by connecting a plurality of LED lighting devices 120 having the configuration according to the first embodiment in series, an external voltage supply line—the first base 122 of the first-stage LED lighting device 120—the first transition. ... the voltage supply line 126-1-the second base 123-the first base 122 of the second stage LED lighting fixture-the first transition voltage supply line 126-1-the second base 123-and so on. A continuous voltage supply path is secured, and a voltage is drawn in parallel from the first transition voltage supply line 126-1 via the connection line or the voltage control circuit 127 inside each LED lighting fixture 120, and Is supplied to the LED line light source 125 of each stage. That is, when the voltage supply line is regarded as a pillar of a ladder, each LED lighting device has a ladder-like shape that becomes a step of the ladder.
For example, when 200 V is supplied from an external voltage supply line, 200 V is applied to the LED line light source 125 inside each LED lighting fixture 120 connected in series, and about 3 V is applied to each LED element. Voltage is supplied. When the contracted power is different or the commercial voltage is different in a country or a region, the design may be made in consideration of the supplied voltage, the number of LEDs of the LED line light source 125, and the like.

The connection line or voltage control circuit 127 is a circuit that controls power supply from the first transition voltage supply line 126-1 to the LED line light source 125. The simplest configuration is a connection line for drawing power from the first transition voltage supply line 126-1 to the LED line light source 125. Although it is possible to provide a capacitor for preventing voltage fluctuation or a voltage stabilizing circuit, a voltage applied to the first crossover voltage supply line 126-1 from the outside is supplied to the LED line as the artificial cultivation apparatus 100. As long as the voltage is within the range allowed for the light source 125, voltage control with higher precision is not required, and it is assumed that the power supply line may be sufficient in many cases. In this example, the connection line 127 is connected to the LED line light source 125 on the front side of the electronic board 124 via a through hole.

Next, the support 140 will be described. The support 140 is a member that supports the LED lighting device 120.
Although the shape and structure of the support 140 are not limited, the support 140 has a concave shape along a part of the outer surface of the LED lighting device 120 or a concave shape contacting at least two points with the outer surface, so that the LED lighting device 120 can be stably mounted. Anything that can be placed or locked may be used. In this example, since the LED lighting device 120 is a straight tube LED lighting device with the 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 lighting device 120. An arc-shaped depression 141 or a V-shaped depression 142 supporting the outer surface of the LED lighting device 120 at two points. In the case where the straight pipe member 121 has a shape different from a cylinder or a structure in which the straight pipe member 121 itself is not provided, the support 140 has any shape of the outer shape of the straight tube type LED lighting device 120. Any shape can be used as long as it can be stably supported along a part of.

5 and 6 are diagrams illustrating examples of the cross-sectional shape of the shape example of the support 140. FIG. 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 in a multi-stage configuration, and supports the LED lighting device 120.
FIG. 5 shows a type having an arc-shaped recess 141 having a shape corresponding to the outer diameter of the LED lighting device 120. The support body 140 is hung from the bottom surface of each of the artificially cultivated plant shelves 110 having a multi-stage configuration, and an arc-shaped depression 141 is provided on the inner surface thereof. The inner diameter of the arc-shaped recess 141 corresponds to the outer diameter of the LED lighting device 120. If the LED lighting device 120 is placed and locked, the LED lighting device 120 can be stably supported.
FIG. 6 shows a V-shaped recess 142 that supports the outer surface of the LED lighting device 120 at two points. The support body 140 is hung from the bottom of each of the artificially cultivated plant shelves 110 in a multi-stage configuration, and the inner surface thereof is provided with a V-shaped concave shape 142. The V-shaped concave shape 142 has a size and an angle at which the LED lighting device 120 can be mounted, and the LED lighting device 120 can be stably supported by mounting and locking the LED lighting device 120.

There may be various variations in the arrangement direction, length, and number of the supports 140.
In this example, since the arrangement direction of the support 140 is related to the first structural pattern in which the LED lighting devices 120 are connected in series with each other, The cross section of the concave shape 141 or the concave shape 142 of the support 140 is provided vertically. In this arrangement direction, if the LED lighting device 120 fits into the concave shape 141 or the concave shape 142 of the support 140, the length direction of the LED lighting device 120 matches the length direction of the artificially cultivated plant shelf 110.
In the first embodiment, it is sufficient that the LED lighting devices 120 are electrically connected in series, and the mechanical arrangement does not necessarily require that the LED lighting devices 120 be arranged in a straight line. It may be bent or angled relatively to each other.

When the length of the support 140 is short, the length of the support 140 is shorter than the length of the LED lighting device 120. Some are provided with a distance. In the example shown in FIG. 2, three support members 140 are arranged at an interval with respect to one LED lighting device 120.
When the length of the support 140 is long, only one is attached to each of the artificially cultivated plant shelves 110 in the multi-stage configuration, and a length corresponding to the length of the artificially cultivated plant shelves 110, that is, artificial cultivation A support 140 is provided over the entire length of the plant shelf 110. However, in this case, since the support 140 exists on the entire lower surface of the LED lighting device 120 to be arranged, if the support 140 is opaque, the illumination light of the LED lighting device 120 is blocked. It is necessary to use a translucent material.

Next, a method of attaching the LED lighting device 120 to the support 140 will be described.
There are at least two types of patterns for the direction of disposing the support 140 and the method of attaching the LED lighting fixture 120.
The first mounting method is a method of mounting the LED lighting device 120 from the side of each support 140.
As shown in FIGS. 5 and 6, the support 140 has a release portion with a part of the side released, and has a hook-like shape, so that the LED lighting device 120 can be inserted from the side. it can. Therefore, the first mounting method is a mounting method in which the LED lighting devices 120 are sequentially inserted from the side of the support 140 and the LED lighting devices 120 are sequentially connected.
As shown in FIG. 7, the LED lighting device 120 is inserted from the side of the support 140, and is placed and locked, while the second base 123 at the rear end of the preceding LED lighting device 120 is As shown in FIG. 3, the first base 122 at the end of the subsequent stage is fitted and connected as shown in FIG. 3, and the LED lighting devices 120 may be connected in series in the length direction. As a result, the LED lighting device 120 can be accommodated in a predetermined position of the arc-shaped depression 141 or the V-shaped depression 142.

In the second mounting method, the LED lighting device 120 is pushed in from the longitudinal direction from the front side of the support 140, and the LED lighting device 120 is slid inside the support 140, so that the support 140 is successively inserted. Is the way.
FIG. 8 is a diagram illustrating a state in which the LED lighting fixtures 120 are sequentially pushed and moved while being supported by being passed through the support body 140 from the longitudinal direction thereof, and are sequentially arranged as a second mounting method. is there.
As shown in FIG. 8, if the LED lighting fixtures 120 are sequentially connected and pushed in from the front direction of the support 140 (from the left end to the right in FIG. 8), the inside of the support 140 slides and passes. When it reaches the predetermined position, it can be accommodated in the arc-shaped depression 141 or the V-shaped depression 142.
Here, in attaching the LED lighting device 120 to the support 140, the first LED 122 and the second nozzle 123 are connected between the adjacent LED lighting devices 120, so that the mounting state is stabilized. .

分かる As shown in FIG. 8, it can be seen that the moving direction of the LED lighting device 120 is the length direction of the LED lighting device 120. A plurality of LED lighting devices 120 are connected in series and integrated, and the LED lighting devices 120 are arranged by being pushed and moved to straddle each support 140.

As shown in FIG. 8, at the time of the mounting operation, the worker fits the subsequent first base 122 to the second base 123 at the rear end of the preceding LED lighting device 120, connects and integrates them. Then, as shown in FIG. 3, the first LED 122 is pushed into the first base 122 of the LED lighting device 120 and the metal insertion pin 1221 is pushed into the first LED lighting device 120. The first base 122 and the second base 123 may be fitted and mechanically connected while being inserted into the metal pin holes 1231 of the second base 123, and then pushed in.
With only such a simple mounting operation, it is possible to complete the installation work of the predetermined number of LED lighting fixtures 120 at the predetermined position and further the electric wiring work.

It is also possible to provide a stopper at the end of the artificial cultivation shelf 110 so that the preceding LED lighting device 120 does not fall off. When pushing the LED lighting device 120 from one end, it is possible to prevent the LED lighting device 120 from accidentally moving to the other end and dropping off from the other end.

FIG. 9 is a diagram schematically illustrating an electrical connection configuration of the LED lighting device 120 according to the first embodiment. As shown in the attachment example shown in FIG. 9A, the first base 122 and the second base 123 that are mechanically adjacent to each other are connected to each other, and the transition voltage inside the LED lighting fixture 120 is mechanically connected. When electricity is supplied by the supply line, the connection is made electrically as shown in FIG.
As shown in FIG. 9A, the plurality of LED lighting devices 120 arranged on the guide rail are arranged in series by connecting the first base 122 and the second base 123, as shown in FIG. 9B. In addition, the first transition voltage supply line 126-1 is also connected in series, and the voltage is drawn in parallel from the first transition voltage supply line 126-1 by the connection line 127, which is a drop-in line, to the LED line light source 125.

Yes, the two parts are connected so as to be able to conduct electricity at the point of connection, and external supply voltage passes through the internal first crossover voltage supply line 126-1 to the next stage LED lighting fixture 120 in order. Then, 200V is applied equally to each LED lighting fixture 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 of the power supplied from the outside to the first transition voltage supply line 126-1 is not particularly limited in the present invention, and various power sources can be applied. A constant voltage source or a constant current source may be used. Generally, the circuit configuration of the constant voltage source is often simpler. When a constant voltage source is used, a source obtained by adjusting a commercial power supply to a predetermined voltage (for example, 200 V) from the outside may be supplied. Note that a circuit that obtains a uniform voltage by applying a switching power supply may be used, but the circuit configuration becomes complicated. Since the present invention is the artificial cultivation apparatus 100, small voltage fluctuations and the like do not often cause a problem. If the external commercial power supply is 200V, the apparatus can be used as it is. It is often sufficient to set the voltage to about 200V. Further, the present invention is also applicable to a voltage source such as PCT / JP2018 / 013206 filed by the inventor in advance.
