Pluggable lighting system for plant cultivation

The invention relates to a pluggable lighting system for a plant breeding station, a kit for installing a lighting module for the plant breeding station, and an LED lamp suitable for the plant breeding station.

lighting fixture.

The term “plant nursery” includes, in particular, greenhouses, special growth housings, vertical farming systems and other in-house

Understand plant breeding systems.

The term "vertical farming" includes viable agriculture and mass production of plant and animal products in metropolitan areas in multi-storey buildings (* farmscrapers). It is therefore a special form of agriculture. Based on circular economy and hydroponics under greenhouse conditions, in building complexes on several levels one above the other all year round

Fruits, vegetables, edible mushrooms and algae are produced.

Lighting systems for plant rearing have become known in a large number of publications. For example, reference is made to EP 3 663 644 B4, which shows a lighting system for growing plants, which consists of a bar-shaped mounting rail on which replaceable LED lighting fixtures are attached, so that a bar-shaped lighting module is created, which, however, is only arranged centrally above an exposure area can be. This has the disadvantage that the corner illumination of the exposure area is insufficient. Another disadvantage is the lack of adaptability of the lighting module formed in this way to different ones

sizes of cultivation areas.

Another lighting system for plant cultivation has become known from US Pat are arranged side by side and each light module a variety of

Has LED elements. The disadvantage of this arrangement is that if one

LED element, the entire bar-shaped light module must be replaced and also that the bar-shaped light modules are not adjustable in length to different cultivation areas and external

Connection cables must be connected to each other.

The type of exposure of self-contained rearing stations is known from EP 2 500 952 B1, and the type of selection of the color spectrum, the exposure time and other parameters useful for plant rearing can be found in US Pat. No. 8,523,385 B2, for example. Those specified there

Breeding parameters are also part of the present invention.

The invention is therefore based on the US 10,111,392 B2 the task of developing a pluggable lighting system for plant cultivation of the type mentioned so that easy adaptability of the lighting of plants in different cultivation areas at optimal

and homogeneous illumination of the exposure area is possible.

To solve the problem, the invention is characterized by the features of a

Plant breeding station according to independent claim 1 characterized.

According to a further independent feature of the invention according to independent claim 6, a kit for assembling a plant breeding station is provided, in which the light module for illuminating plants can be adapted to different dimensions of cultivation areas and in particular to different housings. For this purpose, this inventive idea provides that the kit consists of a selectable number of LED lighting fixtures, which can be connected to one another with a selectable number of plug-in beams in a load-transmitting and current-conducting manner in the manner of plug-in frames with LED lighting fixtures connected in between and approximately the area of the cultivation area, in particular fill the interior of the housing in a horizontal plane, thereby achieving uniform illuminance over the entire exposure area, because the LED lighting fixtures are close to the walls of the housing

Breeding station can be arranged or the shape of the

15

20

25

3

Cultivation area can be adjusted and thus an even illumination of the corner areas is guaranteed. The possibility of adapting to the shape of the cultivation area means that the cultivation area can also be rectangular, triangular or polygonal and the modular, pluggable lighting system can always be adapted to different

cultivation areas is possible

According to a further independent feature of the invention corresponding to independent claim 8, a lighting module is described which consists of a number of electrically conductively interconnected LED lighting fixtures arranged at a mutual distance from one another, the LED lighting fixtures having electrically conductive and load-transmitting pluggable

Plug-in beams can be connected to form a frame-shaped light module.

All three inventive concepts of the independent patent claims 1, 6 and 8 aim to enable the floor area (exposure area) of the plant-rearing station to be illuminated as uniformly as possible, regardless of its contour. The invention therefore provides for the creation of a lighting module which consists of individual separate LED lighting elements which are detachably connected to one another in a current-conducting and load-transmitting manner by means of plug-in beams. It is thus possible for the first time to also achieve uniform illumination of the exposure area at the corners, which was previously possible with conventional beams suspended from the center of the ceiling according to US Pat. No. 10,111,392 B2 or EP 3 663 644 B1

was not possible.

The use of plug-in beams with LED lighting elements connected between them in a load-transmitting and electrically connected manner leads to an optimal adaptation of a frame-shaped lighting module created from them to the exposure area

a plant breeding station. This makes it possible for the first time according to the subject matter of claim 2 that for

Achieving uniform exposure of the exposure area the number of

LED lighting fixtures and the fixture connecting the lighting fixtures

Plug-in beams form a frame which is approximately the size of the

Exposure area corresponds.

This framework can be used as a self-contained framework, e.g. B. as a rectangular frame or as a square frame or as a half-open frame (e.g. in a T or I shape), whereby it is particularly advantageous that due to the attachable LED lighting fixtures, it is always ensured that these are also arranged in the corner area of the frame can order a uniform

To enable illumination of the exposure area in the corner area.

So was considered particularly advantageous that for an exposure area of z. B. 40 x 40 cm, two LED lighting fixtures are used that are spaced apart and connected to one another by a simple plug-in beam, or alternatively, for an exposure area of 60 x 60 cm, three lighting fixtures are arranged in the form of an approximately T-shaped frame, or that for an exposure area of around 80 x 80 cm, four LED lighting fixtures form a self-contained square frame, or that for an exposure area of 100 x 100 cm, six LED lighting fixtures form a self-contained square frame with further LED lighting fixtures in between in the central area, or that for an exposure area of 120 x 120 cm cm nine LED lighting fixtures have a light-emitting frame in the form of a rectangular frame with additional ones arranged in the interior

Form LED lighting fixtures.

Thus, according to the feature of claim 4, a lighting module results, which is formed from a peripheral, self-contained frame consisting of plug-in beams with lighting modules arranged in between, the LED lighting elements preferably being located in the corners of the frame and on a case-by-case basis

are also arranged in between.

It is thus possible for the first time according to the subject matter of claim 5 that the approximately frame-shaped lighting module consisting of plug-in beams and LED lighting fixtures almost completely fills the interior of the housing and

is additionally advantageously arranged in the housing in a height-adjustable manner. The

15

20

25

Term "housing" also includes greenhouse or tent housing or vertical

Indoor rearing stations and other indoor rearing stations.

By adapting the frame-shaped lighting module to the interior of the housing, which is almost completely filled, a particularly even light is achieved

illuminated exposure area is reached.

Independent claim 6 describes a kit for assembling a plant rearing station with a light module, the kit consisting of a selectable number of LED lighting fixtures with a selectable number of load-transmitting plug-in beams for adapting the lighting module to different dimensions of cultivation areas of the plant rearing station and electrically conductive in the form of plug-in frames with intervening LED lighting elements can be connected to one another and thus approximately fill the interior of the housing in a horizontal plane to produce a uniform illuminance or

almost cover the cultivation area.

Thus, according to the dimensions of the housing of the plant nursery or the area and contour of the cultivation area, the length of the frame parts and the number of LED lighting fixtures that are load-bearing and

are electrically connected to the plug-in bars can be selected.

A control computer is preferably assigned to the kit, which—depending on the application—control and/or a number of different parameters

can regulate.

Such parameters are described, for example, in AT 11 329 U1. In AT 520043 A2, which goes back to the same applicant, a configuration of an illumination of an exposure area is described, which is also the subject

of the present invention.

Such parameters for use in dark rearing stations are, for example, also the subject of EP 2 500 952 B1, the disclosure content of which

should also be covered by the present invention.

A lighting module designed according to independent claim 8 consists of a number of LED lighting units which are electrically connected to one another and are arranged at a mutual distance from one another, the lighting module being characterized in that mechanical plug connectors are arranged on the housing of the LED lighting units, which are connected to associated mechanical plug connections from plug-in beams that can be plugged into it to conduct current and transmit load to form a frame-shaped light module

are connectable.

It is preferred if the light module is arranged in the housing of the rearing station so that it can be adjusted in height, and it is particularly preferred if the height adjustability of the light module is controlled by the control computer as a function of the growth height of the exposed plants and, if necessary, of the time

can be regulated automatically.

Additional features of the lighting module are the subject matter of dependent claims 11 to 17.

In a brief summary, the features of the invention can be as follows

to be discribed:

It is a modular plant lighting system consisting of a variable number of LED lighting fixtures and one or more connecting bars, preferably designed as plug-in bars, which allow all modules to be electrically connected to a single power source,

which is part of the system.

The number of lighting modules and their position on a horizontal plane are determined depending on the length and width of the area to be illuminated and

the distance between this surface and the lower part of the

15

20

7

The lighting system is defined in such a way that, from a distance of about 20 cm between the area to be illuminated and the lower part of the lighting system, a homogeneity of the illumination received from the area to be illuminated of more than 75% is guaranteed. This means that the maximum value received at any point of the illuminated area is not greater than 1/3 of the minimum value of the received illumination, this value being expressed in umol/m2/s. Comparable lighting systems according to the

Technology only achieve homogeneity values up to a maximum of 35%.

The length of each connecting bar is determined according to the number of LED lighting fixtures to be connected for a given size area to be illuminated and their position on a horizontal plane, such as

it is defined by the above requirements.

Each LED lighting fixture consists of a box-shaped body with three plug-in connectors in the upper part, which allow the module to be connected to a power source, either via an electrical cable or the connection bar. The lower part of the case contains a circuit board with integrated LEDs. This circuit board is protected by a glass pane that

attached to the bottom of the case.

Finally, the housing has a screw thread at the top for receiving a ring or hook for a hanging system.

Each link bar consists of an aluminum profile incorporating 2-conductor cables, fitted with a connector at each end for connection to the LED lighting fixtures.

The system also includes a "grow controller" unit that allows the light intensity and lighting duration to be adjusted according to the needs of each phase of the grow

Adjust plant growth with a single action. The subject of the present invention does not only result from that

Condition

FIG. 1 shows a schematic of a rearing station 1, a number of plant pots 16, each with a plant 17 planted therein, being placed in a grid arrangement 21 on the floor area 9 of the rearing station 1 in a box-shaped housing 2a. The box shape of the housing is only to be understood symbolically. In principle, any shaped housing can be used. It was also pointed out in the general description that the rearing station can also be part of a greenhouse or a vertical farming system. The representation of the housing 2a and the tent arrangement described below is therefore only an example

do not understand or limit the scope of the invention.

Of course, the invention is not limited to the arrangement of plant pots 16 with plants 17 in the cabinet-like housing 2a. Plant benches or a total of a plant bed covering the floor area 9 can also be used

a large number of plants 17 planted there may be present.

The box-shaped housing 2a is shown only schematically. According to Figures 2a-2e to be described later, it can also be used as a tent housing 2

be trained.

The housing 2a consists of a rear wall 3, two adjoining side walls 5 and a front wall 4, which can preferably be opened in order to allow access to the bottom surface 9 and the plants 17 arranged there. It is not shown that there is still a roof wall 6 and that still

suitable ventilation and humidification systems are in place.

In this exemplary embodiment, the interior space 7 formed by the closed housing 2a defines the cultivation area 9 to be illuminated and accommodates a frame-shaped lighting module 10 which—according to the description below—consists of a number of LED lighting fixtures 12, which are electrically conductive with the aid of plug-in beams 22 and are connected to each other in a load-transmitting manner. The frame-shaped lighting module 10 is fastened in the housing 2a in a height-adjustable manner with the aid of suspensions 11 , although it is not shown that the height can be adjusted automatically by one or more lifting motors, which influence the length of the suspensions 11 . The height can be adjusted automatically by a control computer 13 depending on the distance 19 between the light-emitting underside of the

Light module 10 and the top of the plants 17 are set.

Accordingly, in a preferred embodiment, the height adjustability is determined by the distance between the contour line 18 formed by the plants 17

and the underside of the light module 10 is automatically controlled.

Lateral openings 8 can also be arranged in the side walls 5 for the introduction of additional signal or supply cables. In the exemplary embodiment shown, the control computer 13 is electrically connected to the LED lighting elements 12 in the lighting module 10 with the aid of a control line 15 and regulates their exposure duration, exposure intensity, spectral color and others

Growth parameters relating to the light output of the light-emitting module 10.

15

12

The control computer 13 is supplied with mains electricity via the mains line 14 .

The frame-shaped lighting module 10 thus forms an exposure surface 20, 20a that also illuminates the corners, as will be explained later with reference to FIG

will be explained.

Figures 2a to 2e show different dimensions of housings in the

shown embodiment consist of tent housings 2a-2e.

This makes it clear that the walls 3-6 of these tent housings 2a-2e can be made of a flexible material. There are not shown scaffolding poles

available to quickly assemble and disassemble such a tent housing 2a-2e.

It is also shown schematically that the front wall 4 of the tent housing 2

is open and can be closed with a zipper.

In the embodiment shown, the tent housing 2a has a cultivation area 9 of 40×40 cm; the tent housing 2b according to FIG. 2b has a cultivation area 9 of 60×60 cm; the tent housing 2c according to FIG. 2c has a cultivation area 9 of 80×80 cm; the tent housing 2d according to Figure 2d has a cultivation area 9 of 100 x 100 cm and the tent housing 2e according to Figure 2e has a cultivation area 9 of 120 x 120

Cm.

Figure 3 shows as an exemplary embodiment the exposure area 20a formed by the tent housing 2e with the grid dimensions 120 x 120 with the grid arrangement 21

for setting up the plant pots 16 in each grid square.

FIG. 4 shows a modular system 31 consisting of a number of kits 36a to 36e, with which different frames 37a to 37c can be created. It is indicated schematically how the light distribution 24a to 24e (see also Figure 5 to Figure 9) of the LED lighting fixtures 12 takes place in connection with the plug-in beams 22 according to the size of the tent housing 2 shown in Figures 2a to Figure 2e. The LED lighting fixtures

12 are also in the frame corners 38a to 38c arranged to a

15

20

25

30

13

uniform illumination of the edge areas of the exposure area 20a to 20e

(See Fig. 5 to 9) to achieve.

For example, the exposure variant 23a shows that a plurality of LED lighting fixtures 12 in conjunction with a number of plug-in beams 22 results in a frame-shaped lighting module 10a in conjunction with a control computer 13, this variant for the exposure situation in the tent housing 2e

Figure 2e is preferred.

In another exposure variant 23b it is shown that a plurality of LED lighting fixtures 12 in conjunction with six plug-in beams 22 results in the frame-shaped lighting module 10d, in the corners of the frame and also in the

Area of the frame sides, the LED lighting fixtures 12 are arranged.

In the case of the lighting variable 23c, a total of four plug-in beams 22 are plugged together with four LED lighting fixtures 12 to form a square frame,

whose lighting situation will be explained later in FIG.

With exposure variant 23d, two plug-in bars become a T-shaped one

Frame assembly with three LED lighting fixtures 12 plugged together.

In the case of the lighting variant 23e, a single plug-in beam 22 with LED lighting elements 12 connected at each end becomes a beam-shaped one

Light module 10a assembled.

The exposure variants 23a-23e of the modular system according to FIG

4 resulting lighting situations are shown in Figures 5 to 9 in more detail.

In the upper part of each figure, the frame 10a-10e assembled from the modular system 31 according to FIG

Distribution of the LED lighting fixture 12 results.

The resulting exposure area 20a-20e can be seen below in FIGS. 5 to 9 and also the resulting exposure area

Grid arrangement 21 for the installation of the plant pots 16 in each square.

It is thus clear that a multiplicity of exposure variants 23a-23e can be achieved with a modular system 31 according to FIG the right exposure variant 23a-23e selected and

be plugged together.

As an example of a bar-shaped light module 10d and 10e, FIGS. 10 and 11 show that the height 25 of the respective light module 10a-10e is less than 9 cm Light module 10a-10e is given, so that the height of the housing 2, 2a of the rearing station 1 can be kept low. The height of the plug-in beams 22 is preferably only 4.5 cm. This means that narrow housing arrangements with light modules that are optimally adapted to them can be used, so that because of the low overall height, even two light modules can be arranged one above the other in alignment or offset from one another. This is a particular advantage with vertical

farming systems.

Figure 12 shows a further exemplary embodiment that, with a T-shaped frame of a lighting module 10d, the possibility is created of attaching a cutout 27 approximately in the middle area of the plug-in beam 22 and installing a plug connector 26 there, which is suitable for being attached perpendicularly to the middle area of the Plug-in bar 22 to connect a further plug-in bar 22 connected to it in a load-transmitting and conductive manner. FIG. 12 also shows that the respective LED lighting fixtures 12 are arranged in a housing 33 and on the upper side of the housing 33 there is a corner connector 28 for accommodating the plug-in beam connected thereto

22 and the associated electrical connections are provided.

FIG. 13 shows a lighting module 10a, which is suitable for the larger exposure variant 23a, the parts originating from the modular system 31 corresponding to the exposure variant 23 (see FIG. 4) being assembled into a double frame in which both the LED

Lighting fixtures 12 are arranged in the corner sides as well as in the middle.

In the case of exposure variant 23a, Figure 14 shows the size distribution of the LED lighting fixtures 12 in the interior 7 of a housing 2, 2a, where it can also be seen that the LED lighting fixtures 12, due to their arrangement in the form of a closed frame (see Figure 13 ) can be placed very close to the outer wall of the housing 2, 2a, like this

is represented schematically by the distance 20 cm in FIG.

An exposure area of 120×120 cm is thus created in FIG

the modular system 31 with the exposure variant 23a is shown in FIG.

Figure 15 shows a preferred embodiment for the formation of an LED lighting fixture 12, which essentially consists of a - preferably made of a light metal alloy - housing 33, the underside of which is covered by a cover glass 40, behind which in the manner of a grid arrangement a plurality of LED elements 32 are arranged in a circuit board. The cover glass 40 is held in the housing 33 in an exchangeable manner with the aid of the glass holder 29 . The type of distribution of the LED elements 32 on the board can be changed within wide limits and to the respective lighting situation

be adjusted.

The electrical plug-in connections 30 are also shown schematically,

which will be explained with reference to the later figures.

FIG. 16 shows the top view of the housing 33 of the LED lighting fixture 12, with a number of cooling ribs 34 being present on or in the housing and three being offset at an angle of 90° to one another in the area of a corner connector 28

FIG. 18 shows the mode of operation of the modular system according to the invention, with the representation that a number of LED lighting fixtures 12 and a number of plug-in beams 22 and a control computer 13 a

frame-shaped light module 10c can be created.

FIG. 19 shows that the control computer 13 (also called the control unit) can be plugged into an electrical connection in the area of the corner connector 28 with its control line 15 . Detail 1 shows the unplugged state and detail 2 shows the plugged in state

control line connector 15.

FIG. 20 shows a preferred exemplary embodiment of an electrical and mechanical plug-in connection according to FIG

embodiment shown forms a square profile.

The invention is not limited to this shape of the plug-in profile 50 . The plug-in profile 50 can also be rectangular, oval or polygonal. The plug-in profile 50 on the side of the plug-in bar 22 is assigned an associated plug-in receptacle on the side of the housing 33 of the LED lighting fixture 12 . A plug-in frame 49 is provided on the housing 33 in the area of an insertion opening 39, which is laterally delimited by insertion bevels 44

As already explained above, the hollow profile 46 of the plug-in beam 22 can also have a different shape, and it must only be ensured that the end-side plug-in profile 50 resulting from the hollow profile 46 can be plugged onto the plug-in frame 49 on the housing in a form-fitting manner. In this

Sealing rings can also be arranged in the connection area.

In addition to the screw-nut connection shown, which engages through the aligned bores 52, 53, further connection means not shown in the drawing are also provided. Such connecting means can preferably be designed as an easily detachable quick-release fastener. Such a quick-release fastener can be designed as a snap hook, a clip fastener, a toggle fastener or a clamp fastener or a latch fastener. In the latter case, the latching closure consists of a latching ball which can be displaced in a spring-loaded manner in a recess and which, in the coupled state, engages in an opposite recess in the other part.
