Description

Artificial cultivation device, LED lighting device, and electrical connection method for LED lighting device of artificial cultivation device

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

2. Description of the Related Art In recent years, artificial cultivation technology for plants, which grows plants indoors using artificial lighting, has attracted attention, instead of the conventional traditional farming method using natural light from the outside. In artificial cultivation, it has become possible to control the flowering and promote the growth of plants by irradiating light with a wavelength suitable for blue, red, far red, etc., depending on the plant species.
As a light source for artificial illumination, high-output LED elements (light emitting diode elements) have been developed in recent years, and so-called LED illuminators have begun to be used in place of conventional white bulb illumination and fluorescent illumination. In particular, the white LED element is suitable for artificial lighting for an artificial plant cultivation device because it can emit light of many wavelengths, and the LED element has the characteristics of small size, power saving, and long life. Together, they are gaining momentum in popularization. In addition, since the LED elements have relatively uniform wavelengths of emitted light and the heat generation is relatively small, it has been proposed to use an artificial lighting device in which a large number of LED elements are arranged as a lighting fixture for artificial cultivation.

In the prior 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. 19, the plant cultivation device disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2013-17397) has a cultivation rack 3 having a mounting shelf 4 on which the cultivation tank 2 is mounted, and above the mounting shelf 4. And LED lighting fixtures 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 to each other by horizontal members 9 to form a single vertical frame 7, and a pair of left and right vertical frames 7A7B are bridged. The cultivation rack 3 is formed by bridging the connecting members 18. A large number of supporting portions 6 which are protrusions are projected on the side surfaces of the vertical columns 8 of the vertical frame 7, and the LED lighting device 5 is attached to the supporting portions 6. It is disclosed that the LED lighting device 5 is fixed to the vertical column 8 by screwing, riveting, or the like to the receiving portion 32 of the supporting portion 6, as in the step 0028 of the publication.

Further, in the plant cultivation device disclosed in Patent Document 2 (JP-A-2005-006162), as shown in FIG. 20, an LED lighting fixture 5 is arranged in a cultivation rack, and the LED lighting fixture 5 has a frame. -Shaped frame 15, 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 lamps 16 and having a reflection surface facing downward. The reflective member 17 is provided.
The left and right ends of the LED lamp 16 are fitted into the notches 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 pressing members 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 with the pressing member 25 via the elastic member 29.

As described above, in both Patent Document 1 and Patent Document 2, a structure called a cultivation rack is assembled, and after the end portion of the LED lighting device is placed at a predetermined position on the cultivation rack, screwing, riveting, etc. It is fixed in place to be placed in a predetermined position to create a stable state.

JP 2013-017397 A JP 2015-006165 A

One of the problems in the conventional LED lighting device is the cost and load of electrical work in the cultivation rack of each LED lighting device.
If the number of LED lighting devices arranged in the unit of the artificial cultivation device is large, and if it is a large-scale plant factory, a large number of the units of the artificial cultivation device are installed, the LED lighting of each one The amount of electrical wiring work for tools becomes enormous. As a result, 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 become a major obstacle to the spread of artificial cultivation devices in plant factories in the future.

In the case of the plant cultivation device disclosed in Patent Document 1, it is necessary to attach the LED lighting device to the support portions 6 provided in large numbers on the side surfaces of the vertical columns 8 of the vertical frame 7. As described in the paragraph 0028 of the publication, the LED illuminator 5 needs to be fixed to the receiving portion 32 of the supporting portion 6 on the vertical column 8 by screwing, riveting, or the like, and then electrical wiring work must be performed. Installation work and electric wiring work of a considerable worker are required for one LED lighting fixture 5, and the work of performing electrical wiring work by mounting a large number of LED lighting fixtures 5 in a complicated manner requires both construction period and cost. It becomes huge.
In the plant cultivation device of Patent Document 1, even if the LED lighting device 5 is not screwed or riveted to the receiving portion 32 of the supporting portion 6, one LED lighting is applied to a long cultivation rack. It is necessary to place the tool 5 by hand and perform electrical wiring work.

Also in the plant cultivation device disclosed in Patent Document 2, as shown in FIG. 20, when arranging the straight tube type LED lighting device 16 in the cultivation rack, the left and right ends of the straight tube type LED lighting device 16 are arranged 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 by screwing the left and right ends of the LED lamp 16 from above with the pressing member 25 via the elastic member 29. It is necessary to fix it and perform electric wiring work. After all, a considerable amount of work is required for each LED lighting fixture 5, and the work of performing electrical wiring work by mounting an extremely large number of LED lighting fixtures 5 in a complicated manner is enormous in terms of period and cost. turn into.
Similarly, in Patent Document 2, even when the straight tube type LED lighting device 16 is not screwed from above by the pressing member 25 and is not riveted, the LED lighting device 5 is manually attached to a long cultivation rack one by one. After careful placement, complex electrical work needs to be done.

In view of the above problems, the present invention reduces the installation work and electric wiring work of a LED lighting device at a predetermined location on a structure such as a rack as in the related art, and the installation work of an artificially grown plant shelf and the cost are reduced. It is an object of the present invention to provide an artificial cultivating device.

In order to achieve the above-mentioned object, the artificial cultivation device of the present invention is an artificial cultivation plant shelf for accommodating a plant to be artificially cultivated, a first connecting portion, a second connecting portion, the first connecting portion and the above. An electronic substrate provided between the second connecting portions, an LED line light source in which a large number of LED chips are attached to the electronic substrate, and a power supply so as to pass between the first connecting portion and the second connecting portion. A crossover voltage supply line for supplying a voltage, an LED illuminator equipped 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 to face the artificially grown plant shelf. A support body that supports the LED lighting device and the first connection part and the second connection part of the LED lighting device are provided, or the first connection part and the second connection part are provided. On the other hand, external terminals provided on the support body each having an electrical connection means and receiving an external voltage supply, and a plurality of the LED illuminators are supported by each support body in the long axis direction. In the LED lighting device group arranged in series and arranged in the above, a bridge crossover wiring cord is provided for electrically connecting and electrically connecting the external terminal of the present stage and the external terminal of another stage adjacent to each other by bridge connection.

With the above configuration, in the LED lighting device group, the voltage supply of the LED lighting device of the present stage is received from the LED lighting device of the previous stage or the next stage or the support body via the bridge connecting wiring cord, and the LED of the next stage or the previous stage is received. It includes a structure in which the voltage supply of the illuminator is supplied from the LED illuminator of the present stage or the support through the bridge-crossing wiring cord.

In the above configuration, if the crossover voltage supply line is the crossover voltage supply line that passes the electric power supplied through the first connecting portion through the inside of the same LED lighting device to the opposing second connecting portion, Electrical components for supplying a voltage to each LED illuminator of the LED illuminator group are not provided on the artificially grown plant shelf and its bottom surface, and are configured only by the components suspended and supported by the support body. The Rukoto.

Here, as the constituent elements suspended and supported by the support body, "the first connecting portion of the LED illuminator of this stage"-"the crossover voltage supply line of this stage"-"the LED illuminator of this stage" "Second connection part"-"External terminal of this stage"-"Bridge crossover wiring code"-"External terminal of next stage"-"First connection part of LED illuminator of next stage"-"Next transition" "Voltage supply line"-"Second connection part of LED light fixture of next stage"-"External terminal of next stage"-"Bridge crossover cord"-... The structure ensures the voltage supply. When the external terminal is provided on the support, the “support” is interposed between the “first connection part” or the “second connection part” and the “external terminal”. ..

With the above configuration, in the work of arranging the LED lighting device on the artificially cultivated plant shelf, it is sufficient to support the LED lighting device at a predetermined position through the support, and the electric wiring is attached from the outside by connecting the bridge crossover wiring cord. The electrical connection is easily completed via the "bridge crossover wiring cord" that is attached from the outside and the "crossover voltage supply line" that is built inside.
In the prior art, the supporting body is an electrically constructed socket, which mechanically supports the LED lighting device and also serves to energize the first connecting portion and the second connecting portion. Many. However, in this case, it is necessary to separately perform electrical wiring work inside the artificially grown plant shelf, and electrical elements such as a ballast must also be installed by electrical work. As a result, work costs such as electrical work and the addition of ballasts, money costs, and time costs were incurred, which was a heavy burden.
In the present invention, an electric component for supplying a voltage to each of the LED illuminators of the LED illuminator group is not provided on the artificially-cultivated plant shelf and its bottom surface, but is suspended and supported by a supporter. It consists of only elements. Therefore, electric wiring work inside the artificially grown plant shelf is unnecessary, and electric elements such as a ballast are also unnecessary. Therefore, it has an advantage in work cost, money cost, and time cost.

Here, the electrical wiring to the LED lighting device group will be described. The external terminals of the first connection portion or the second connection portion on the end side of the LED lighting device located at the end of the LED lighting device group are connected to an external voltage supply line cord that receives voltage supply from the outside. I shall. Alternatively, when an external terminal for electrically energizing the first connection portion or the second connection portion is provided on the support body side, an external voltage supply line for receiving a voltage from the outside to the external terminal of the support body It is assumed that the cord is connected.
As described above, if the first connection portion or the second connection portion on the end side of the LED lighting device located at the end of the LED lighting device group is connected to the external voltage supply line cord that receives the voltage supply from the outside, A voltage can be easily supplied to the LED lighting device group, and special electric work and electric elements such as a ballast are not necessary.

In the structure of the present invention, as described above, the electrical connection across the plurality of LED lighting fixtures is such that the first connection portion of the LED lighting fixture of the present stage-the crossover voltage supply line of the present stage-the current stage of the present invention. Second connection part of LED lighting device-bridge crossover wiring cord-First connection part of LED lighting device of the next stage-Next crossover voltage supply line-Second connection part of LED lighting device of the next stage-Bridge Crossover wiring code---, etc., to ensure a continuous "voltage supply path", and inside each LED lighting device, the crossover voltage supply line is connected in parallel via a connection line or a voltage control circuit. A voltage is drawn and supplied to each LED line light source. That is, when the “voltage supply path” is regarded as a ladder column, each LED lighting device is a ladder-type connection that serves as a step of the ladder.

Here, there are no particular electronic components in the connection line, and there are types that include only lead-in wiring, and there may be types that incorporate a small number of electronic components such as capacitors. In the case of the artificial cultivating apparatus of the present invention, a slight voltage fluctuation that does not damage the LED element often does not cause a problem in actual operation, and in that case, only the lead-in line is sufficient.

Also, the voltage control circuit may include an electronic circuit having a voltage stabilizing function. If the external commercial power supply is unstable, each LED lighting fixture may be provided with a stabilizing function by a voltage control circuit, but at the place where the external commercial power supply is pulled into the building of the artificial cultivation device. In some cases, it may be possible to deal with it by providing a voltage stabilizing device collectively.

In the case of a general LED illuminator, for example, 200V is supplied between the first base and the second base, and if the internal LED line light source has 90 elements, each element theoretically Is supplied with a voltage of about 3V.
On the other hand, in the structure of the present invention, the first connecting portion at the head of the succeeding LED lighting device is inserted into the second connecting portion at the rear end of the preceding LED lighting device and connected in order. Therefore, it differs from the conventional one in that each first connection portion does not have a mechanism in which a voltage is supplied from the outside.

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 to the LED line light source from the outside 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. In general, a constant voltage source often has a simpler circuit configuration. When the constant voltage source is used, a commercial power source externally transformed to a predetermined voltage (for example, 200 V) 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, small voltage fluctuations are not a problem in many cases, and a transformer adjustment of a commercial power supply is sufficient in many cases. Further, a voltage source such as PCT/JP2018/013206 filed earlier by the applicant of the present invention is also applicable.

Next, the electrical connection when the entire artificial cultivation device is assembled two-dimensionally will be described. That is, this is a case of a two-dimensional array in which a plurality of LED lighting tool groups are arranged in parallel. The external voltage supply line cords of the adjacent LED lighting device groups are connected to each other. In this case, in the two-dimensional array, the LED lighting devices of the LED lighting device group are electrically connected to each other in the one-dimensional direction by the bridge crossover wiring cord and the crossover voltage supply line, and the external voltage supply is performed in the two-dimensional direction. The wire cords are electrically connected to each other.
It is possible to easily supply a voltage to the two-dimensionally arranged LED lighting fixtures, and no special electrical work or electrical elements such as ballasts are required.
However, further, when the artificially cultivated plant shelves are arranged in a three-dimensional array as a multi-stage configuration, the LED illuminators of the LED illuminator group are connected to each other in a one-dimensional direction with a bridge crossover wiring cord and a crossover voltage. It is assumed that they are electrically connected by a supply line, and the external voltage supply line cords are electrically connected in the two-dimensional direction. It is also possible to branch some of the external voltage supply line cords in the vertical direction and connect them in the three-dimensional direction.

Next, devising the structure of the first connecting portion, the second connecting portion, and the support will be described.
As the structure of the first connecting portion and the second connecting portion, it is possible to adopt a structure in which each end face is provided with an insertion pin and further an external terminal electrically connected to the insertion pin. In this case, as the support body, a pair is provided so as to face each other so as to sandwich both ends of the LED lighting device, and has a structure provided with a pin hole adapted to the insertion pin on the opposing end faces. The support is attached to a predetermined position of the artificially-cultivated plant shelf, and the LED lighting device is set to a predetermined position.

The positions of the "external terminals" of the first connecting portion and the second connecting portion are provided at locations where they can be connected to the bridge crossover wiring cord from the outside even when they are attached to the support. Is preferred.
Note that, in this configuration, the specific shapes of the first connecting portion, the second connecting portion, and the matching supporting body are not particularly limited, but machines other than electrical elements such as "external terminals" that are responsible for electrical connection. A general-purpose pin shape can be used as the “insertion pin” for the target element.

In addition, as another structure example of the support, a recess shape along the outer surface of the LED lighting device or a recess shape that abuts at least two points on the outer surface is provided, and the support body has a longitudinal axis with respect to the axis. The depression-shaped cross section may be provided vertically.
In this case, it is no longer necessary to directly mechanically support the first connecting portion and the second connecting portion, but it is merely a support for mounting the LED lighting device. This may be a mechanical structure, and the electrical connection is realized by a bridge crossover wiring cord, a crossover voltage supply line, and an external voltage supply line cord.
Furthermore, as another structural example of the support, a support part extending upward from the first connection part and the second connection part on the straight tube type LED lighting device side and a direct support on the artificial cultivation plant shelf side. It may be a combination of guide rails that movably support the support portion on the side of the tubular LED lighting device.
With the above configuration, in the work of arranging the straight tube type LED illuminator on the artificially grown plant shelf, the straight tube type LED illuminator is moved along the guide rail through the support portion, so that each straight tube The type LED illuminator can be moved to each predetermined position in the guide rail and arranged, and the arrangement work is simplified.

In this case, the support portion may have a runner for the guide rail, and the guide rail may have a structure in which the runner of the support portion runs.
In this case, in the installation work of the straight tube LED lighting device, the straight tube LED lighting device can be moved to a predetermined installation position by causing the runner of the support body to run along the guide rail. Work becomes easy.
Further, as another example of the structure of the support body, the guide rail may include a slider that slides the support body portion, and the support body portion may include a slide body that travels by the slider of the guide rail. ..
In this case, in the installation work of the straight tube type LED lighting device, the straight tube type LED lighting device can be moved to a predetermined installation position by sliding the sliding body of the support portion along the guide rail, Installation work is also simple.

In the present invention, not only the artificial cultivation device but also the LED lighting device itself applied to the artificial cultivation device is the subject of the patent.
That is, a first connecting portion, a second connecting portion, an electronic substrate provided between the first connecting portion and the second connecting portion, and an LED line light source in which many LED chips are attached to the electronic substrate. A crossover voltage supply line that supplies a power supply voltage so as to pass between the first connection unit and the second connection unit, and a connection line or a voltage control circuit that supplies power from the crossover voltage supply line to the LED line light source. An external terminal that is provided on each of the first connecting portion and the second connecting portion and receives a voltage from the outside, and a plurality of the LED lighting fixtures that are compatible with the external terminal and that are connected in series. In the arrayed state, the bridge connecting wiring cord is provided for electrically connecting the external terminals of the first connecting portion of the present stage and the second connecting portion of the next stage to electrically connect them.

Further, the method for energizing the LED lighting device of the artificial cultivation device according to the present invention is arranged such that a plurality of the LED lighting devices are arranged on the artificial cultivation plant shelf of the present invention, and the artificial cultivation plant shelf is supported via the support. A plurality of the LED lighting devices arranged in series and arranged are connected by a bridge-crossing wiring cord.
Since the arrangement and electrical connection of the LED lighting device can be easily performed, it is an efficient method of electrically connecting the artificial lighting device to the LED lighting device.

According to the artificial cultivation device of the present invention, in the work of disposing the LED lighting device on the artificial cultivation plant shelf, after supporting the LED lighting device at a predetermined position via the support, the electrical wiring is a bridge crossover wiring cord and It can be easily connected via the crossover voltage supply line inside the LED lighting fixture, which reduces the installation work and electrical wiring work of the LED lighting fixture at a predetermined place, and reduces the installation work and cost of the artificial cultivation plant shelf. It is possible to provide an artificial cultivation device.

The first mouthpiece 122 that is the first connection portion 122 and the second mouthpiece 123 that is the second connection portion 123 are members provided at both ends of the straight pipe member 121 in this configuration example. Here, the first base 122 is provided at the left end, and the second base 123 is provided at the right end.
In the example shown in FIG. 2, the first cap 122 is provided with a metal insertion pin 1221 and the second base 123 is provided with a metal insertion pin 1231.
The specific shapes of the first base 122, the second base 123, and the compatible socket-type support 140a are not particularly limited, but mechanical shapes other than electrical elements such as "external terminals" that carry out electrical connection. A general-purpose pin shape can be used as the "insertion pin" for the element.

For example, the inserting pins of the first connecting portion and the second connecting portion may have a so-called "G13 type" standard structure that is often used in the base of a fluorescent lamp. In this case, the pinhole in the socket-type support may be adapted to the "G13 type" insertion pin.
However, the general standard "G13 type" itself is a mechanical support structure and also requires an electrical connection structure on the socket side. In the case of the first embodiment, the first connection portion and the second connection portion are provided. Even if the insertion pin of the connection portion of "G13 type" is used, the socket type support 140a only mechanically supports, and the socket type support 140a has an energization structure for the "G13 type" insertion pin. Is unnecessary. At present, it is becoming widespread as a connection part for LED lighting fixtures, and the cost can be reduced by using the G13 type.
It should be noted that in recent years, the structure of the standard "JEL800" is becoming widespread. The shape of the insertion pins of the first connection portion and the second connection portion may be “JEL800”. In this case, the pinhole in the socket-type support may be adapted to the "JEL800" insertion pin. Of course, in the present invention, the insertion pin shapes of the first connection portion and the second connection portion, and the pinhole shape of the socket type support body are not limited to "G13" and "JEL800".

Further, although the first base 122 and the second base 123 have the same shape as an example, they may have different shapes.
Since the environment of the artificial cultivating apparatus 100 has a lot of moisture and humidity, it is possible to improve the waterproof property by devising a device such as providing a cover on the outside.
FIG. 3 is a diagram simply illustrating a connection structure of the first ferrule 122 that is the first connecting portion 122 and the second ferrule 123 that is the second connecting portion 123 according to the first embodiment.
In the example shown in FIG. 3A, the first cap 122 is provided with a metal insertion pin 1221, the second base 123 is provided with a metal insertion pin 1231, and FIG. By mating with the support 140a shown in Fig. 3, they are mechanically connected as shown in Fig. 3C, and the postures of the two are stabilized.

Next, as shown in FIG. 3A, the first base 122 and the second base 123 are each provided with an external end portion 130 and an internal connection circuit 131 as electrical connection elements.
The external end portion 130 receives a voltage supply from the outside through the bridge crossover wiring cord 132, and has a shape that can be connected to the bridge crossover wiring cord 132. In the present invention, the external terminal 130 may be provided in the first connection portion and the second connection portion of the LED lighting device 120, and the first connection portion and the second connection portion may be respectively provided. A structure provided on the socket type support 140a provided with an electrical connection means may be used. In the first embodiment, the former first connection portion and the second connection portion are provided. As will be described later with reference to FIG. 4, in this example, the first base 122 and the second base 123 are provided in the vicinity of the upper portions thereof, respectively.

The internal connection circuit 131 is a circuit that connects the insertion pin 1221 of the first base 122 and the insertion pin 1231 of the second base 123 to the external terminal 130, and is supplied from the bridge crossover wiring cord 132. Voltage is supplied to the insertion pin 1221 of the first base 122 and the insertion pin 1231 of the second base 123 by the internal connection circuit 131 via the external terminal.

The bridge crossover wiring cord 132 connects the external terminal 130 of the present stage and the external terminal 130 of the other stage adjacent to each other in a bridge connection to electrically connect the electrical connection. This structure will be described later with reference to FIG.

Next, the support 140 will be described. The support 140 is a member that supports the LED lighting device 120. The shape and structure of the support 140 are not limited, and any type of support that stably mounts or locks the LED lighting device 120 can be used, and various variations are possible.
Although the support 140 may have various variations in the present invention, the support 140a shown in the first embodiment is a socket type, and the insertion pin 1221 of the first base 122 and the insertion pin of the second base 123 are provided. 1231 is provided with a connecting portion 141a that fits with each other, and the LED lighting fixture 120 can be mechanically supported by fitting together. In this example, the support 140a itself is attached to the artificially grown plant shelf 110 or a structure in the vicinity thereof so that the LED lighting device 120 faces the plant planted on the artificially grown plant shelf 110. It is provided where it can be attached. If the artificially grown plant shelf 110 has a multi-stage structure, the support 140a may be provided at a predetermined position on the bottom surface of the artificially grown plant shelf 110 in the upper stage.

There may be various variations in the arrangement direction, length, and number of the supports 140.
As an arrangement, the LED lighting devices 120 do not necessarily have to be aligned in a straight line, and may be bent in a zigzag shape or may be angled relative to each other.
In addition, in the first embodiment, the support 140a is a configuration example without an electrical connection structure. An example in which the support has an electrical connection structure will be described in Example 2.

Next, the bridge connection using the bridge crossover wiring cord 132 will be described.
FIG. 4 is a diagram showing a state in which the LED lighting fixtures 120 are arranged in series by the support 140a, and the LED lighting fixtures 120 adjacent to each other are connected by the bridge crossover wiring cord 132.
The bridge connecting wiring cord may be one that electrically connects the external terminals 130 of the LED lighting device 120 to each other, but here, two types are shown.
The first type has a structure in which the connection between the external terminal 130 and the bridge crossover wiring cord 132 is a plug-in type and is detachably connected. The detachable structure is not limited, but for example, so-called plug-sockets, which are mechanically fitted to each other and electrically conductive, may be used.
As shown in FIG. 4B, insert the bridge crossover wiring cord 132 into each of the external terminal 130 of the LED lighting device 120 on the left side of the drawing and the external terminal 130 of the LED lighting device 120 on the right side of the drawing. Thus, from the insertion pin 1231 of the second connecting portion 123 that is electrically connected to the crossover voltage supply line 126 near the rear end of the LED lighting device 120 on the left side in the figure, via the internal connection circuit 131 and the external terminal. The bridge crossover wiring cord 132 is energized, and the bridge crossover wiring cord 132 is passed through the internal connection circuit 131 via the external terminal 130 of the first connection portion 122 near the start end of the LED lighting device 120 on the right side in the drawing. It is possible to form a voltage supply path that energizes the crossover voltage supply line 126 and the insertion pin 1221 that energizes. The interior of the LED lighting device 120 is energized by the crossover voltage supply line 126 to the insertion pin 1231 of the second connecting portion 123 facing each other.
The second type, as shown in FIG. 4C, has a structure in which the bridge crossover wiring cord 132 includes a connection terminal 1321 for connecting the bridge crossover wiring cords 132 to each other, and the external terminal 130 and the bridge crossover wiring cord One end of 132 is fixedly connected, and a structure is provided in which the other ends of the front and rear bridge crossover wiring cords 132 are connected to each other via a connection terminal 1321. The fixed attachment structure is not limited, but may be a cord extending from the external terminal 130 of the LED lighting device, for example. The other end of the bridge crossover wiring cord 132L extending from the external terminal 130 of the LED illuminator 120 on the left side of the figure and the bridge crossover extending from the external terminal 130 of the LED illuminator 120 on the right side of the figure. The other ends of the wiring cords 132R are connected to each other near the center of the drawing via a connection terminal 1321. By the connection via the connection terminal 1321, the supply voltage is conducted between the left and right LED lighting devices 120.

The electronic board 124 is a board on which the LED line light source 125 and the voltage control circuit are mounted. In this example, as shown in FIG. 2, the electronic board 124 is formed in a linear shape or in a strip shape and is provided over the entire length of the straight pipe member 121.

The LED line light source 125 is a large number of LED (white light emitting diode) elements in which a large number of LED chips are arranged in a line along the electronic board 124 in the straight tube member 121 and mounted. As shown in FIG. 2 and the like, in this configuration example, the LED line light source 125 is mounted on the front (front surface) side of the straight tube member 121 so that 30 LEDs 10 irradiate the front with light. Therefore, the front side (front side) of the LED line light source 125 is the light irradiation surface.

The LED element is a chip having a white LED element light emitting surface on the front surface and an electrode surface on the back surface. In this example, the LED element is a surface mount type (SMD type) LED element. It shall emit light that appears visually pure white.
The LED elements are arranged linearly to form an LED line light source 125. For example, 30 LEDs 30 are mounted so as to emit light to the front.
Although a detailed description of the control circuit for controlling the LED element is omitted, the control circuit receives the voltage supplied from the outside and controls the LED line light source 125 to supply necessary power.

The crossover voltage supply line 126 according to the first embodiment is a metal wire that conducts electricity between the first base 122 and the second base 123 at both ends of the LED lighting device 120. In this example, a metal wire is provided on the back surface side of the electronic substrate 124 so as to pass through it in the length direction, and power can be supplied to the LED line light source 125 on the front surface side of the electronic substrate 124 through the through holes. ing. In the configuration example of the first embodiment, by providing the crossover voltage supply line 126, electricity is supplied from the first base 122 to the second base 123 of the LED lighting device 120.

As described above, in the configuration example of the first embodiment, the electrical connection between the LED lighting devices 120 is made by the path shown in FIG. 4B and the crossover voltage supply line 126 inside the LED lighting device 120.
As described above, the voltage supply path is formed by the components that are suspended and supported by the socket-type support 140a for the LED lighting device group in which the LED lighting devices 120 are arranged in series. That is, the first connecting portion 122 of the LED illuminator 120 of this stage, the crossover voltage supply line 126 of this stage, the second connecting portion 123 of the LED illuminator of this stage, and the internal connection circuit 131 of this stage. External terminal 130 of the stage-Bridge crossover wiring cord 132-External terminal 130 of the next stage-Internal connection circuit 131 of the next stage-First connection part 122 of the LED lighting device 120 of the next stage-Transition voltage supply line 126 of the next stage -The second connection portion 123 of the next-stage LED lighting device 1203-The next-stage internal connection circuit 132-The next-stage external terminal 130-The bridge crossover wiring cord 132-, and the voltage supply is secured in the series-arranged direction. It becomes a structure.

FIG. 5 is a diagram simply showing voltage supply paths in a group of LED lighting devices arranged in series.
If the relationship of the fine electrical connection terminals shown in FIG. 4 is simplified, as shown in FIG. 5, the bridge crossover wiring cord 132 and the crossover voltage supply line 126 are continuously connected to form a voltage supply path. I know that That is, when the “voltage supply path” is regarded as a pillar of a ladder, the LED line light source 125 of each LED lighting device 120 is a ladder-type connection that becomes a step of a 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 device 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 each 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.

As shown in FIG. 5B, a connection line or a voltage control circuit is provided to control the power supply from the crossover voltage supply line 126 to the LED line light source 125. The simplest configuration is a connection line for drawing power from the crossover voltage supply line 126 to the LED line light source 125. Although it is possible to provide a capacitor for preventing voltage fluctuation or a voltage stabilizing circuit, the voltage applied to the voltage supply line 126 from the outside is allowed to the LED line light source 125 as the artificial cultivation device 100. If the voltage is within the range, it is assumed that more accurate voltage control is not required, and thus the power lead-in line may be sufficient in many cases. In this example, the connection line is connected to the LED line light source 125 on the front surface side of the electronic substrate 124 via a through hole.

The voltage supply to the external terminal 130 of the first connecting portion 122 or the second connecting portion 123 on the end side of the LED lighting device 120 located at the end of the LED lighting device group will be described.
It is necessary to supply an external voltage to the LED lighting device 120 at the beginning of the LED lighting device group. Therefore, a structure may be adopted in which an external voltage supply line cord that receives voltage supply from the outside is connected to the external terminal 130 of the LED lighting device 120 at the start end of the LED lighting device group. The socket-type support 140a on the end side of the LED lighting device 120 located at the end may have a different shape from the socket-type support 140a in the middle as the end.

Here, the power source of the power supplied from the outside 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. 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 the artificial cultivation device 100, small voltage fluctuations are not a problem in many cases, and can be used as it is if the external commercial power source is 200V. If the external commercial power source is 100V, the boosting adjustment of the transformer is performed. It is often sufficient to set the voltage to 200V. Further, a voltage source such as PCT/JP2018/013206 filed by the present inventor in advance is also applicable.
Note that the mechanism of the two-dimensional voltage supply in the two-dimensional array of the LED lighting device group will be described in the third embodiment.

Example 2 is of a type in which LED illuminators are connected in series in the longitudinal direction, and the support body is a socket-type support body, but the external terminals are on the socket-type support body side. The socket-type support body is electrically connected to the first connection portion and the second connection portion, and is electrically connected to the first connection portion and the second connection portion through the socket-type support body. This is an example of connection. Although the socket type support is interposed, the voltage is supplied by the second connection in which the voltage supplied from the external terminal of the socket type support to the first connection portion is opposed through the crossover voltage supply line inside the LED lighting device. Of the socket type support from the second connection portion to the external terminal of the adjacent socket type support body via the external terminal of the socket type support body through the bridge connecting wiring cord. It is to be delivered from the support to the first connection portion of the LED lighting device. The mechanical support of the LED lighting device is performed by a socket type support.

Further, FIG. 6C is a side view showing a state in which the socket type support 140b is attached to the LED lighting device 120b.
In the second embodiment as well, the LED lighting device 120b is an example of the straight tube type LED lighting device, but as described in the first embodiment, the LED lighting device 120b does not necessarily have to be the straight tube type LED lighting device. Instead, it can be applied to various LED lighting fixtures.

As shown in FIGS. 6A and 6B, the LED lighting device 120b includes a straight tube member 121, a first base 122, a second base 123, an electronic substrate 124, an LED line light source 125, and a crossover voltage.

As shown in FIG. 7( d ), the connection portion 141 b is fitted with the insertion pin 1221 of the first base 122 and the insertion pin 1231 of the second base 123, so that the connection part 141 b is changed to the one shown in FIG. In addition to mechanical support, electrical connection is also made to energize external terminals via the internal connection circuit 131.
The external end portion 130 receives a voltage supply from the outside via the bridge crossover wiring cord 132, and the LED lighting device 120b is electrically connected via the bridge crossover wiring cord 132 and the socket type supporting portion 140b. To be done.

In FIG. 8, in the second embodiment, the LED illuminators 120b are arranged in series by the socket-type support 140b, and the LED illuminators 120b adjacent to each other are connected by the bridge crossover wiring cord 132. It is a figure which shows a mode.
Similar to the first embodiment, the bridge crossover wiring cord may be any one as long as it electrically connects the external terminals 130 provided on the support of the LED lighting device 120, but there are also two types here.
The first type has a structure in which the connection between the external terminal 130 and the bridge crossover wiring cord 132 is detachably connected in the same manner as in the first embodiment. The detachable structure is not limited, but for example, so-called plug-sockets, which are mechanically fitted to each other and electrically conductive, may be used.
As shown in FIG. 8B, by inserting the bridge crossover wiring cord 132 into the external terminal 130 of the socket-type support 140b, the crossover voltage supply near the rear end of the LED lighting device 120b on the left side in the figure is supplied. From the plug-in pin 1231 of the second connecting portion 123 that is electrically connected to the wire 126, the bridge crossover wiring cord 132 is energized via the internal connection circuit 131 of the socket type support 140b and the external terminal 130, and the bridge crossover wiring is performed. From the cord 132 to the insertion pin 1221 of the first connection portion 122 via the internal connection circuit 131 via the external terminal 130 of the socket type support 140b near the start end of the LED lighting device 120b on the right side in the figure. It is energized and a voltage is supplied to the opposite rear end side by the crossover voltage supply line 126.
The second type is, as shown in FIG. 8C, a structure in which the bridge crossover wiring cord 132 includes a connection terminal 1321 capable of connecting the bridge crossover wiring cords 132 to each other, and the external terminal 130 and the bridge crossover wiring cord One end of 132 is fixedly connected, and a structure is provided in which the other ends of the front and rear bridge crossover wiring cords 132 are connected to each other via a connection terminal 1321. The fixed attachment structure is not limited, but may be a cord extending from the external terminal 130 of the LED lighting device, for example. The other end of the bridge crossover wiring cord 132L extending from the external terminal 130 of the LED illuminator 120 on the left side of the figure and the bridge crossover extending from the external terminal 130 of the LED illuminator 120 on the right side of the figure. The other ends of the wiring cords 132R are connected to each other near the center of the drawing via a connection terminal 1321. By the connection via the connection terminal 1321, the supply voltage is conducted between the left and right LED lighting devices 120.

Next, the voltage supply to the external terminal of the socket type support 140b on the end side of the LED lighting device 120 located at the end of the LED lighting device group according to the second embodiment will be described.
It is necessary to supply an external voltage to the LED lighting device 120 at the beginning of the LED lighting device group. Therefore, a structure may be adopted in which an external voltage supply line cord that receives a voltage supply from the outside is connected to the external terminal 130 of the socket type support 140b at the start end of the LED lighting device group. The socket-type support 140b on the end side of the LED illuminator 120 located at the end may have a different shape from the socket-type support 140b that is in the middle as an end.
Note that the mechanism of the two-dimensional voltage supply in the two-dimensional array of the LED lighting device group will be described in the third embodiment.

Example 3 describes a two-dimensional array of LED lighting devices. By arranging in parallel the LED illuminator groups in which the LED illuminators shown in the above-described first and second embodiments are connected in series in the longitudinal direction, the LED illuminators are arranged two-dimensionally and a voltage is applied to them. It is to supply.
FIG. 9 is a diagram simply showing the configuration of the LED illuminator 120 at the beginning of the LED illuminator group or the external voltage supply line cord 133 in the socket type support 140b at the beginning of the LED illuminator group. ..
FIG. 9A shows a configuration example in which the external voltage supply line cord 133 is provided in the first connecting portion 122 of the LED lighting device 120 at the start end of the LED lighting device group.
FIG. 9B shows a configuration example in which the external voltage supply line cord 133 is provided in the socket type support 140b at the start end of the LED lighting device group. The socket-type support 140b on the end side of the LED illuminator 120 located at the end may have a different shape from the socket-type support 140b that is in the middle as an end.

The external voltage supply line code 133 is a code that receives a voltage supply from the outside, and here, the power source of the power supplied from the outside may be either a constant voltage source or a constant current source. 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. Since the artificial cultivation device 100 is used in the present invention, a small voltage fluctuation or the like is not a problem in many cases, and the external commercial power source may use 200 V as it is. Further, a voltage source such as PCT/JP2018/013206 filed by the present inventor in advance is also applicable.

FIG. 10 is a diagram showing a manner in which adjacent external voltage supply line cords 133 at the start ends of the LED lighting device groups shown in FIG. 9 are connected to each other. Note that, as an example, the configuration is shown in which the external voltage supply line cord 133 is provided in the first connecting portion 122 of the LED lighting device 120 shown in FIG. 9A.

FIG. 11 is a diagram briefly showing a two-dimensional array of LED lighting fixtures 120 obtained as a result of connecting adjacent external voltage supply line cords 133 as shown in FIG. 10 and a voltage supply mechanism for them.
As shown in FIG. 11, the LED illuminator groups at each stage are arranged in series in the lateral direction (X direction) in the figure. In addition, the LED illuminator groups in each stage are arranged in parallel in the vertical direction (Y direction) in the drawing. Furthermore, there are multiple stages in the front or depth direction (Z direction) in the figure. In this way, they are three-dimensionally arranged in the X direction, the Y direction, and the Z direction. The commercial power supply 135 is shown at the origin in the matrix, and a voltage is supplied from the commercial power supply 135 in both the X direction and the Y direction and a voltage is supplied to each LED lighting device 120 located at the intersection of the matrix. In this example, a vertical external voltage supply line cord 134 that connects the commercial power supply 135 to each node in the Z direction is further provided in a multi-tiered structure, and a voltage can be supplied three-dimensionally. Has become.

That is, in the X direction, a voltage is supplied to the LED lighting group of each stage by the crossover voltage supply line 126 and the bridge crossover wiring cord 132, and an external voltage is supplied to the LED lighting group of each stage in the Y direction. The voltage is supplied by the supply line code 133, and further, the voltage is supplied also in the Z direction and developed in each XY direction in each stage.
As described above, in the three-dimensional array, the voltage is supplied to each LED lighting device 120 by the structure in which all the electrical components related to the voltage supply are hung by the socket type support 140. Such a mechanism does not exist in the prior art, and was first realized by the present invention.
According to the conventional technology, it is necessary to perform an electric wiring structure and a complicated electric wiring work on the ceiling, the inside of the artificially grown plant shelf 110 and other structures. Electric wiring work is unnecessary, and after installing the LED lighting device, simply connecting the bridge crossover wiring cord 132 and the external voltage supply cord 133 to the outside makes it easy to complete the electric wiring work.

Example 4 shows an example of various support variations. In Embodiments 1 to 3, the socket 140 is used as the support 140 by way of example. Although it has been described in Examples 1 to 3 that the shape and structure of the support 140 are not limited, various other variations of the support will be described here.

(Runner type)
First, the first support 140c of Example 4 will be described.
FIG. 12 is a diagram simply showing the structure of the runner type first support 140c according to the fourth embodiment.
The first support 140c is a combination of the two configurations, and is an example of the support 140c including the suspension type support 140-1c and the guide rail 140-2c, and the runner 141 rotates. The suspension type support 140-1c moves with respect to the guide rail 140-2c.

The guide rail 140-2c is a component of a part of the support 140c, and is a member disposed so as to face the irradiation surface of the straight tube type LED lighting device 120 on the artificially grown plant shelf 110.
In the example of FIG. 12, the upper surface is attached to a structure such as the outer surface of the bottom surface of the artificially cultivated plant shelf 110, and as shown in FIG. Two rows of rails 144c are provided aside.

As shown in FIGS. 12(a), 12(b), and 12(c), the suspension support 140-1c includes the first connecting portion 122 and the second connecting portion 122 of the straight tube type LED lighting device 120.
