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 straight tube type LED luminaires for artificial lighting is devised. The artificially cultivated plants are not particularly limited.

In recent years, instead of the traditional traditional farming method using natural light from the outside world, the artificial cultivation technique of plants that grows plants by using artificial lighting indoors has attracted attention. In artificial cultivation, it has become possible to control flowering and promote growth of plants by irradiating light with a suitable wavelength such as blue, red, and far red depending on the plant species.
As a light source for artificial lighting, the development of high-output 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 the amount of heat generated 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 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 a straight tube type LED illuminator 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 form one 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 a straight tube type LED illuminator 5 is attached to the support portions 6. As shown in the 0028 stage of the same publication, it is disclosed that the straight tube type LED illuminator 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 apparatus disclosed in Patent Document 2 (Japanese Unexamined Patent Publication No. 2015-006162), as shown in FIG. 16, a straight tube type LED illuminator 5 is arranged in a cultivation rack, and a straight tube type LED is provided. The luminaire 5 is detachably attached to a frame-shaped frame 15, a plurality of LED lamps 16 detachably attached to the frame 15, and a frame 15 so as to be located above the LED lamp 16, and has a reflective surface. Is provided with a plate-shaped reflective member 17 facing downward.
In the straight tube type LED lamp 16, both left and right ends 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 the holding member 25 is detachably attached to the horizontal frame 15. Is fixed by. 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 portion of the straight tube type LED illuminator is placed in a predetermined position on the cultivation rack and then screwed. By fixing it with rivets or the like, it is arranged in a predetermined position to create a stable state.

Japanese Unexamined Patent Publication No. 2013-017397 Japanese Patent Application Laid-Open No. 2015-006165

One of the problems in the conventional straight tube type LED lighting device is the load of the arrangement work on the cultivation rack of each straight tube type LED lighting device.
The number of straight tube type LED lighting fixtures arranged in the unit of artificial cultivation equipment is large, and in the case of a large-scale plant factory, many units of the artificial cultivation equipment are installed, and the artificial cultivation equipment unit is installed. There is a problem that the installation cost of the plant 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 a straight tube type LED illuminator 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 the 0028 stage of the same publication, the straight tube type LED illuminator 5 needs to be fixed to the vertical support 8 by screwing, rivet fixing, etc. to the receiving portion 32 of the support portion 6, one by one. The installation work of a considerable number of workers is required for the straight tube type LED luminaire 5, and the work of installing an extremely large number of straight tube type LED illuminators 5 in a complicated manner requires a huge amount of installation period and installation cost. It ends up.
In the plant cultivation device of Patent Document 1, even if the straight tube type LED illuminator 5 is not screwed or riveted to the receiving portion 32 of the support portion 6, each one is attached to a long cultivation rack. It is necessary to bring in the straight tube type LED luminaire 5 and place it carefully by hand. Further, of course, since it is not screwed, it becomes unstable, and there is a possibility that the straight tube type LED illuminator 5 may fall or come off during the operation of the plant factory.

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 type LED lamp 16 are placed on both the left and right frames of the horizontal frame 15. The straight tube type LED lamp 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 16 and again, it is necessary to install a considerable number of workers for each straight tube type LED luminaire 5, and an extremely large number of straight tube type LED luminaires 5 are complicatedly attached. In the future, the installation period and installation cost will be enormous.
Similarly in Patent Document 2, even if the straight tube type LED lamp 16 is screwed from above by the holding member 25 and is not riveted, the straight tube type LED lighting tool 5 is provided for each long cultivation rack. It must be carried in and carefully placed by hand. Further, of course, since it is not screwed, it becomes unstable, and there is a possibility that the straight tube type LED lamp 16 may fall or come off during the operation of the plant factory.

In view of the above problems, in the present invention, as in the conventional case, the straight tube type LED luminaires are manually placed one by one in a predetermined mounting place on a structure such as a rack and screwed. It is an object of the present invention to provide an artificial cultivation device capable of reducing the work of the artificial cultivation plant shelf, easily disposing a straight tube type LED luminaire at a predetermined position, and stably attaching the LED lighting equipment.

In order to achieve the above object, the artificial cultivation device of the present invention comprises an artificially cultivated plant shelf for accommodating artificially cultivated plants, a plurality of straight tube type LED lighting fixtures, and the artificially cultivated plant shelf so as to face the artificially cultivated plant shelf. The straight tube type LED for the artificially cultivated plant shelf is provided with a support for supporting the straight tube type LED luminaire and a guide rail for movably supporting the support for supporting the straight tube type LED luminaire. In the arrangement work of the luminaire, the straight tube type LED luminaire is moved along the guide rail by moving the support and the straight tube type LED luminaire supported via the support. Is characterized in that it can be moved to each predetermined position in the guide rail and arranged.

With the above configuration, in the work of arranging the straight tube type LED luminaire on the artificially cultivated plant shelf, the straight tube type LED luminaire supported via the support can be moved along the guide rail, and each straight tube can be moved. The type LED illuminator can be moved to each predetermined position in the guide rail and arranged.
Regarding the positional relationship between the support, the guide rail, and the straight tube type LED illuminator, the guide rail, the support, and the straight tube type LED illuminator can be in that order.
For example, there is a case where they are arranged in order in the vertical direction, a support is suspended from a guide rail, and a straight tube type LED illuminator is suspended from the support.
Further, for example, there is a case in which they are arranged in order in the horizontal direction, the support is horizontally movably supported from the guide rail, and the straight tube type LED illuminator is horizontally supported from the support.
Further, for example, there is a case in which a support is supported so as to be horizontally movable from a guide rail, and a straight tube type LED illuminator is suspended downward from the support.

Here, in the above configuration, as a combination of the guide rail and the support, there may be a runner type in which the runner is arranged on the support side and a slider type in which the slider is arranged on the guide rail side.
The runner type has a configuration in which the support is provided with a runner for the guide rail, while the guide rail is provided with a lane in which the runner of the support runs. In the arrangement work of the straight tube type LED illuminator, the straight tube type LED illuminator supported via the support can be moved along the guide rail to a predetermined arrangement position.
The slider type has a configuration in which the guide rail is provided with a slider that slides the support, while the support is provided with a sliding body that travels by the slider of the guide rail. In the arrangement work of the straight tube type LED illuminator, the straight tube type LED illuminator supported via the support can be slid along the guide rail and moved to a predetermined arrangement position.

In either of the above runner type and slider type, the straight tube type LED illuminator and the support can be integrated.
For example, in the runner type, the runner of the support has a rotating member such as a roller, and the guide rail side may have a member such as a lane on which the roller of the support travels, or the support. The runner has a sliding plate that slides without a rotating member such as a roller, and the guide rail side includes a member such as a lane on which the sliding plate of the support travels.
In addition, as a slider type, the support has a sliding plate that slides, and if there is a rotating member such as a roller in the guide rail, the support has a sliding plate that slides, and the roller in the guide rail. This also includes the case where there is no rotating member such as, and there is also a lane that promotes gliding.
That is, it can be said that the straight tube type LED luminaire itself is provided with a runner or a slider, and if the straight tube type LED luminaire has such a structure, it can be arranged in an artificial cultivation device. If you attach the straight tube type LED illuminator to the guide rail as it is and push it in as it is, you will be able to run with a runner or a slider, and the arrangement work will be very easy. In other words, this straight tube type LED luminaire can be expressed as "a straight tube type LED luminaire with a runner or a sliding body".

Next, the mounting direction of the straight tube type LED illuminator will be described.
There are at least two mounting directions for the straight tube type LED illuminator with respect to the guide rail.
The first mounting direction is a direction in which the moving direction of the straight tube type LED illuminator in the guide rail is the length direction of the straight tube type LED illuminator. In this mounting direction, one straight tube type LED luminaire is pushed in from the end of one guide rail from the length direction to be mounted, then moved to the back and sent in order, and the next straight tube type LED luminaire. Can be arranged in series with a plurality of straight tube type LED luminaires for one guide rail by inserting them one after another in the order of pushing them in from the length direction, moving them to the back and sending them in order.
Although one support can be provided for one straight tube type LED luminaire, two or more supports may be provided for one straight tube type LED luminaire in consideration of stability and balance. preferable. In the case of the two cases, the balance is improved if each is provided so as to support the first base and the second base or the vicinity of the left and right ends of the straight pipe member.

Further, as a variation of the first mounting direction, the support is long, and a plurality of guide rails are provided in parallel, and the support straddles the plurality of guide rails so as to be orthogonal to each other and is along the guide rails. The straight tube type LED illuminator is provided orthogonal to the support, and the moving direction along the guide rail is the length direction of the straight tube type LED illuminator. By moving the straight tube type LED illuminator along the guide rails with respect to the parallel guide rails via the support to the guide rails, a plurality of luminaires are connected in series with the plurality of parallel guide rails. Straight tube type LED luminaires can be arranged by mechanical connection and electrical connection.

When this first mounting direction is adopted, mechanical connection and electrical connection between a plurality of straight tube type LED luminaires will be described.
For example, if a straight tube type LED luminaire is attached to a guide rail from the side to which the first base is attached and is slid and sent out, the tail of the straight tube type LED luminaire mechanically precedes. If the structure is such that the first base at the head of the subsequent straight tube type LED illuminator can be inserted and connected to the second base in the above, the connection can be made in order. That is, a plurality of straight tube type LED illuminators can be connected in series for one guide rail. Here, the electrical connection will be described. The straight tube type LED lighting fixture includes a first base, a second base, a straight pipe member passed between the first base and the second base, an electronic board, and a large number of LEDs on the electronic board. An LED line light source with chips mounted in series is included, and in the case of general straight tube LED lighting equipment, for example, 200V is between the first base and the second base attached to the external socket. If the internal LED line light source has 90 elements, a voltage of about 3 V is theoretically supplied to each element. Here, in the present invention, the first base at the head of the succeeding straight tube type LED luminaire is inserted into the second base at the tail of the preceding straight tube type LED luminaire and connected in order. Therefore, unlike the conventional case, the first base and the second base are not configured to be supplied with voltage from an external socket.

Therefore, in the present invention, as the structure of the straight tube type LED lighting tool, a first base, a second base, a straight pipe member passed between the first base and the second base, and an electronic substrate are used. An LED line light source with a large number of LED chips mounted in series on an electronic board, a crossover voltage supply line that transfers power supplied through the first base to the second base, and an LED from the crossover voltage supply line. The configuration is provided with a connection line or a voltage control circuit that supplies power to the line light source. In this way, by passing the voltage supply line inside, the external voltage supply line- (first base of the straight tube type LED lighting fixture of the first stage-cross voltage supply line-second base)-( The first base of the straight tube type LED lighting equipment in the next stage-the crossing voltage supply line-the second base) -... Inside the tool, voltage is drawn in parallel from the crossing voltage supply line via a connection line or a voltage control circuit and supplied to each LED line light source. In other words, if the voltage supply line is regarded as a ladder support, each straight tube type LED illuminator is a ladder type that becomes a ladder rail.
Here, as the connection line, there is no particular electronic component, and a type in which only the lead-in wire is wired is included, 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 device 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 straight tube type LED luminaire may be provided with a stabilization function by a voltage control circuit, but the external commercial power supply to the building of the artificial cultivation device may be provided. In some cases, it may be possible to deal with this by providing a voltage stabilizer at the pull-in point.

In the case of the straight tube type LED luminaire having the above configuration, the connection structure in which the first base and the second base adjacent to each other in the guide rail are mechanically connected to each other and electrically energized. In addition, a plurality of straight tube LED luminaires arranged on the guide rail are lined up in series by connecting the first base and the second base, and the electrical connection draws voltage in parallel from the crossing voltage supply line. The LED line light source can be energized.

As a specific example, the electrical connection structure between the first base and the second base is a place where one is a metal insertion pin and the other is a metal pin hole, and the connection is made by fitting the two. It is connected so that it can be energized, and the supply voltage from the outside is passed to the straight tube type LED luminaire in the next stage in sequence through the internal crossing voltage supply line, and the voltage is evenly applied to the all straight tube type LED luminaire. It is applied and drawn in parallel to the internal LED line light source, and a voltage of about 3 V is applied to each LED element. 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.
In addition, it is preferable that the waterproof structure is provided at the place where the two are connected.

Here, the electric power supplied to the voltage supply line from the outside, the electric power supplied to the LED line light source via the connection line or the voltage control circuit will be described. These power sources are 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 has a simpler circuit configuration in many cases. 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. It should be noted that 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 voltage fluctuations 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 mounting direction is a direction in which a plurality of guide rails are provided in parallel and the arrangement direction of the straight tube type LED illuminator with respect to the guide rail is orthogonal to the guide rail. In this case, a plurality of orthogonal straight tube type LED illuminators are attached to a plurality of guide rails provided in parallel.
For example, if two guide rails are provided in parallel on the left and right, and two supports are provided on the straight tube type LED illuminator, the straight tube type LED illuminator is provided for the parallel guide rails. Each support can be attached to the left and right guide rails side by side in the orthogonal direction, and can be pushed in order to the back side while maintaining the orthogonal posture to move.

In the second mounting direction, the straight tube type LED illuminator is supported so as to be orthogonal to the parallel guide rails via the support body on the guide rails, and is moved along the guide rails. , A plurality of straight tube type LED illuminators can be arranged so as to be orthogonal to each other for parallel guide rails.
As a specific example, a crossover wiring that receives voltage supply by connecting the first bases and the second bases that are adjacent to each other between a plurality of straight tube type LED illuminators arranged in parallel so as to be energized. The configuration is provided with a cord and a connection line or a voltage control circuit for supplying power from the crossover wiring cord to the LED line light source. If the voltage supplied to the crossover wiring cord is 200V, each straight tube type LED luminaire is connected in parallel to the crossover wiring cord, so that the LED inside each straight tube type LED luminaire is connected. 200V may be supplied to the line light source, and a voltage of about 3V may be applied to each LED element.

As the artificial cultivation device, the artificial cultivation plant shelf and the guide rail 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. As for the guide rails, the guide rails of each stage can be provided on the members extending from the artificially cultivated plant shelves in the upper stage, the own stage, or the lower stage.

According to the artificial cultivation apparatus of the present invention, in the work of arranging the straight tube type LED illuminator on the artificially cultivated plant shelf, the straight tube type LED illuminator supported by the support can be moved along the guide rail. It is possible to move each straight tube type LED illuminator to each predetermined position in the guide rail and dispose of it.
If the moving direction of the straight tube LED luminaire in the guide rail is the length direction of the straight tube LED luminaire, one straight tube LED luminaire can be used from the end of one guide rail. Push it in, move it to the back and send it in order, push in the next straight tube type LED illuminator, attach it, move it to the back and send it in order, and insert it one after another. The straight tube LED luminaires of the book can be arranged in series both mechanically and electrically.
If the moving direction of the straight tube LED illuminator in the guide rail is orthogonal to the parallel guide rails, the straight tube LED illuminator is supported so as to be orthogonal to the parallel guide rails. By moving along the guide rails, a plurality of straight tube type LED illuminators can be arranged orthogonally to the parallel guide rails, and can be electrically arranged in parallel.

Hereinafter, examples of the artificial cultivation apparatus of the present invention will be described with reference to the drawings. However, it goes without saying that the scope of the present invention is not limited to the specific uses, shapes, numbers, etc. shown in the following examples. The commercial power supply will be described by taking 200 V as an example, but this is just an example, and the present invention can be applied even when the contracted power is different and the voltage is different depending on the country or region.
As the first embodiment, a configuration example in which the mounting direction of the straight tube type LED illuminator with respect to the guide rail is the above-mentioned first mounting direction is shown. The first mounting direction is a direction in which the moving direction of the straight tube type LED illuminator in the guide rail is the length direction of the straight tube type LED illuminator.

It is a configuration example in which a straight tube type LED illuminator is provided orthogonally to the support.
As the third embodiment, a configuration example in which the mounting direction of the straight tube type LED illuminator with respect to the guide rail is the above-mentioned second mounting direction is shown. The second mounting direction is a direction in which a plurality of guide rails are provided in parallel and the arrangement direction of the straight tube type LED illuminator with respect to the guide rail is orthogonal to the guide rail.

An example of the artificial cultivation apparatus 100 of this invention which concerns on Example 1 is shown.
The artificial cultivation device 100 according to the configuration example of the first embodiment has a configuration including an artificially cultivated plant shelf 110, a straight tube type LED illuminator 120, a guide rail 130, and a support 140.
FIG. 1 is a diagram showing an arrangement relationship of an artificial cultivation device 100, particularly an artificial cultivation plant shelf 110, a straight tube type LED illuminator 120, a guide rail 130, and a support 140. 1 (a) shows a plan view, FIG. 1 (b) shows a front view, and FIG. 1 (c) shows a side view. The detailed structure of the straight tube type LED illuminator 120, the guide rail 130, and the support 140 is not shown.

The artificially cultivated plant shelf 110 is a shelf for storing artificially cultivated plants. In this configuration example, there are a frame portion (vertical frame 111, horizontal frame 112, horizontal plate frame 113) and a container portion 114. The structure, shape, size, length, width, etc. of the shelf are not particularly limited, and the one in FIG. 1 is only an example. In this configuration example, as an example, it has a five-stage configuration.
The basic structure of the artificially cultivated plant shelf 110 is a vertical and horizontal skeleton structure formed by a vertical vertical frame 111 and a horizontal horizontal frame 112, and a horizontal plate frame 113 is provided at each stage. Any structure that can support the container portions 114 side by side in multiple stages can be adopted as the structure of the artificially cultivated plant shelf 110. Detailed explanations and illustrations are omitted here.
In this example, the horizontal plate frame 113 plays a role of supporting the container portion 114 and, as will be described later, a role of supporting the straight tube type LED illuminator 120, the guide rail 130, and the support 140. ing. It is also possible to provide structures separately without sharing the roles of both.

FIG. 2 is a configuration example of the internal structure of the straight tube type LED illuminator 120. FIG. 2 shows an example of the configuration in which the support 140 is integrated, and shows the runner type support 140-1 described later. Even in the case of the slider type support 140-2 described later, the internal structure of the straight tube type LED illuminator 120 may be considered in the same manner.
As shown in FIG. 2, the straight tube type LED illuminator 120 includes a straight tube member 121, a first base 122, a second base 123, an electronic board 124, an LED line light source 125, a crossover voltage supply line 126, and a connection line. It is equipped with 127. Although some configurations such as the connection line 127 are omitted in FIG. 2, they are simply illustrated in FIG. 7.

The straight tube member 121 is a pipe-shaped member that replaces the conventional fluorescent lighting, and is a straight tube member that is passed between the first base 122 and the second base 123. At least the illumination surface is a pipe made of transparent plastic or glass, and is generally cylindrical. However, the straight tube member 121 is integrated with the connecting portion 143 of the support 140, which will be described later, and is a straight tube member. It is an example of integration as a part of the contour of 121. If the straight tube member 121 and the connecting portion 143 of the support 140 are integrated in this way, the work such as assembling the straight tube type LED illuminator 120 and the support 140 becomes unnecessary, and the installation work does not require any work. The structure is such that the straight tube type LED illuminator 120 is provided with the support 140 as a part of the configuration, and the installation work can be made more efficient.
The material of the straight pipe member 121 is a transparent resin material such as a transparent or translucent polycarbonate resin, an acrylic resin, or a methacrylic resin, and has an internal space and is formed in a cylindrical pipe shape. A first base 122 and a second base 123 are provided at both ends. In this configuration example, the axial length of the straight tube type LED illuminator 120 between the first base 122 and the second base 123 attached to both ends of the straight tube member 121 is the same as that of the existing fluorescent lamp. It is the length.

The first base 122 and the second base 123 are members provided at both ends of the straight pipe member 121. Here, the first base 122 is provided at the left end, and the second base 123 is provided at the right end.
The first base 122 and the second base 123 have a connection structure that can be mechanically connected to each other and can be electrically energized.
As a configuration of the first base 122 and the second base 123, a configuration in which the support 140 is integrated is also possible.
In the example shown in FIG. 2, a metal insertion pin 1221 is provided in the first base, and a metal pinhole 1231 is provided in the second base 123, and the size and shape (diameter,) in which both are fitted are provided. Depth).
The two metal pinholes 1221 of the first base 122 and the two metal pinholes 1231 of the second base 123 are the same size as the metal pinholes of the conventional fluorescent lamp base and the conventional base. Or shape may be used.
Further, the first base 122 and the second base 123 are mechanically connected by fitting each other. Further, a protective cover is provided on the outside thereof, for example, a screw-type screw structure is provided at the joint between the two, and the connection can be easily and firmly made by screwing. Since the environment of the artificial cultivation device 100 has a lot of moisture and humidity, the waterproof property can be improved by providing a cover on the outside.

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 substrate 124 is formed in a linear or strip shape and is long, and is provided over the entire length of the straight tube member 121. The electronic substrate 124 is provided near the upper part of the inner surface of the straight pipe member 121.

The LED line light source 125 is a large number of LED (white light emitting diodes) elements in which a large number of LED chips are arranged and mounted in a line along the electronic substrate 124 in the straight tube member 121. As shown in FIG. 2 and the like, in this configuration example, the LED line light source 125 is mounted on the front surface (front surface) side of the straight tube member 121 so that 30 LEDs 10 irradiate the front surface 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 provided with a light emitting surface of a white LED element 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 looks pure white visually.
The LED elements are arranged in a straight line to form an LED line light source 125. For example, 30 LEDs 30 are mounted so as to illuminate the front surface.
Although detailed description of the control circuit for controlling the LED element is omitted, the control circuit receives a voltage supplied from the outside and controls the LED line light source 125 to supply the necessary electric power.

The crossover voltage supply line 126 is a metal wire that energizes between the first base 122 and the second base 123 at both ends. In this example, a metal wire is provided on the back surface side of the electronic substrate 124 in a straight line in the axial direction, and the structure is such that power can be supplied to the LED line light source 125 on the front surface side of the electronic substrate 124 through the through hole. There is. By providing the cross voltage supply line 126, the straight tube type LED illuminator 120 is energized from the first base 122 to the second base 123, and a plurality of straight tube type LED illuminators 120 are connected in series. As a result, all the straight tube type LED illuminators 120 are energized all at once by the cross voltage supply line 126 connected in series.

The connection line or voltage control circuit 127 is a circuit that controls the power supply from the crossover voltage supply line 126 to the LED line light source 125. The simplest configuration is a power lead connection line from the crossover voltage supply line 126 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 applied to the voltage supply line 126 from the outside is within the range allowed for the LED line light source 125 as the artificial cultivation device 100. If it is, it is assumed that there are many cases where a power lead-in wire is sufficient because voltage control with higher accuracy is not required.

In this way, by passing the voltage supply line 126 inside, the external voltage supply line-the first base 122 of the straight tube type LED illuminator 120 of the first stage-the cross voltage supply line 126-the second base 123-A single voltage supply path is secured such as the first base 122-crossing voltage supply line 126-second base 123-... of the straight tube type LED lighting fixture of the second stage, and each of them Inside the straight tube type LED illuminator 120, a voltage is drawn in parallel from the crossing voltage supply line 126 via a connection line or a voltage control circuit 127, and is supplied to the LED line light source 125 of each stage. In other words, if the voltage supply line is regarded as a ladder support, each straight tube type LED illuminator is a ladder type that becomes a ladder rail.
For example, when 200V is supplied from an external voltage supply line, 200V is applied to the LED line light source 125 inside each straight tube type LED illuminator 120 mechanically connected in series, and each of them is supplied. A voltage of about 3V is supplied to the LED element. 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.

FIG. 14 is a diagram briefly showing an electrical connection configuration of the straight tube type LED illuminator 120b according to the third embodiment. As in the mounting example shown in FIG. 14A, when the first base 122 and the second base 123 adjacent to each other in parallel in the guide rail 130 are connected to each other by the crossover wiring cord 128, FIG. As shown in 14 (b), they are electrically connected in series. That is, as shown in FIG. 14A, the voltage supplied from the outside by the connection between the crossover wiring cords 128 of the first base 122 and the crossover wiring cords of the second base 123 is used as a common voltage line. In FIG. 14 (b), it is provided horizontally.
In a plurality of straight tube type LED illuminators 120 arranged in parallel on the guide rail, as shown in FIG. 14 (b), a voltage is drawn in parallel from the crossover wiring cord 128 by a connection line or a voltage control circuit 127 which is a lead wire. Therefore, the LED line light source 125 can be energized.
The supply voltage from the outside is passed to the straight tube type LED illuminator 120 of the next stage in order through the crossover wiring cord 128, and 200 V is evenly applied to each straight tube type LED illuminator 120 connected in parallel. It is applied and drawn into the internal LED line light source 125, and a voltage of about 3 V is applied to each LED element.

Here, the power source of the electric power supplied to the crossover wiring cord 128 from the outside is not particularly limited in the present invention as in the first embodiment, 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 has a simpler circuit configuration in many cases. 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. It should be noted that 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.

With only such a simple installation work, it is possible to complete the installation work at a predetermined position and the electrical wiring work for all of the plurality of straight tube type LED illuminators 120 to be attached to the guide rail 130.

It will be appreciated that various modifications are possible without departing from the technical scope of the invention.
Although the preferred embodiment of the present invention has been illustrated and described above, the present invention can be widely applied as an artificial cultivation apparatus applicable to a plant factory of various plant species.
