Description

[0001] The invention relates to a cultivation system with a light source, also referred to here as light source, which is suitable for heating and cooling the environment by controlled temperature.

[0002] Lighting is used in various forms and dimensions to illuminate different areas of the living space or to provide light for plant cultivation. In the latter case, light-emitting diodes (LEDs) with different wavelengths and combined with plant-specific spectra are usually used. To mimic sunlight, high-performance LEDs are used, which are either passively or actively cooled by a liquid. Actively cooled LED luminaires are particularly interesting for indoor or controlled-environment agriculture.

[0003] For example, KR 1 00959994B 1 describes an LED lighting device with a water cooling option and sensors for activating external room ventilation to cool the space around the LEDs, which has become heated by the waste heat. KR101027205B1 describes a multispectral LED with sensors for adjusting the lighting according to the plant growth cycle, dimming the LED based on the sensor values ​​and thus generating less waste heat. WO2014140416A1 describes an LED luminaire in which the cover plate is used to excite the phosphor, and the LEDs emit light at a temperature of 130°C + / - 30°C, which contributes to heat dissipation in the grow room.

[0004] Since all of these LED lamps do not fully control heat dissipation, cannot operate with a controlled temperature of the lamps and / or cannot cool the grow room, none of these LEDs allows for highly controlled environmental conditions of the PPFD (Photosynthetically Active Photon Flux Density) and the grow room, nor can it sense and / or control the environment depending on the plant cultivation and / or to control the plant cultivation using sensors.

[0005] Based on the cited prior art, it is an object of the present invention to provide a cultivation system with a light source that controls the temperature of the lamps and / or the ambient conditions of a closed cultivation room and / or the plant cultivation itself.

[0006] The present invention solves this problem by providing a cultivation system having the features of claim 1.

[0007] The light-emitting device can also be referred to as an LED. The light source can be a lamp with one or more LEDs.

[0008] The LED preferably consists of at least one wavelength-specific lamp. The lamp is used in an enclosed space for growing plants, e.g., in an indoor farm, a container, or a room where environmental conditions need to be kept constant or at least controlled.

[0009] Furthermore, the light source can preferably be used in sterile rooms, such as clean rooms that have a sterility assurance level (SAL) SAL 10 -5are to be rendered sterile, determined by inoculation with common bacteria such as staphylococci and / or pseudomonads and according to ISO 17664-1:2021, wherein the LED has at least one cooling circuit to maintain the luminaires at a controlled temperature and / or to cool and / or regulate the environment to a specific temperature and / or humidity. Furthermore, the LED is equipped with one or more sensors. This can be done using an electrical support, such as an electrical track. Such a sensor device can be used as an input for controlling the plant cultivation environment and / or the plant cultivation itself. The sensors can preferably be integrated into the housing of the light source, but it is also possible to use the sensor device as a standalone device, not integrated into the LED.

[0010] In a further preferred embodiment of the present invention, the material of a housing of the light source may consist of materials that are sterilizable by conventional sterilizing agents, such as hydrogen peroxide, ozone, perchloroacetic acid, ethanol, isopropanol, steam, high-temperature sterilization and / or ethylene oxide, but not by electron beam and / or gamma ray sterilization.

[0011] Advantageous embodiments of the inventions are the subject of the dependent claims.

[0012] The invention is explained in more detail using an example in the context of a figure. It shows: Fig. 1 is a first schematic drawing of a light-emitting device used in a cultivation system according to the invention; Fig. 2 second schematic drawing of a light-emitting device; and Fig. 3 Cultivation system according to the invention.

[0013] Fig. Figure 1 shows a light source 100, referred to here as a lamp. The light source 100 is a complex body comprising a cooling device 1, such as a heat sink, a condensate collector 2, a cooling fluid 3, an electrical connection 4, a lamp section 5 with a plurality of lamps 5a, and a sensor device 6, all of which are arranged in a housing 50 of the light source 100. This housing is provided with a light exit window 51.

[0014] Each luminaire has at least one luminous section 5, i.e. an LED with at least one specific wavelength of emitted radiation from the electromagnetic spectrum. Preferably, these luminous sections are light-emitting diodes (LEDs) of a specific color and / or a combination of LEDs with at least one other technology, e.g., laser or halogen. Since each luminaire in the lamp emits light and heat, and the latter is dissipated by both the lamp body and the luminous flux of the luminaire, the environment in which the lamp is installed is consequently heated. Furthermore, each luminaire in the lamp has a color- and technology-specific temperature, above which the emitted luminous flux decreases with increasing temperature. This so-called junction temperature has a major influence on the luminous flux and thus on the photosynthetic photon flux density (PPFD).The PPFD is responsible for optimal CO2 fixation and ultimately for plant growth.

[0015] The temperature of a luminaire section 5, e.g., an LED, also influences the specific wavelength emitted. By controlling the temperature, the spectrum can be kept more specific than with uncooled luminaires.

[0016] Each luminaire is connected to at least one coolant circuit that regulates the luminaire's temperature to a preset and / or target temperature. The setpoint and / or target temperature can be set using a commercially available control mechanism, such as a Siemens Simatic S7-15000, and measured by a closed-loop sensor, such as a commercially available TST310 RTD sensor from Endress + Hauser.

[0017] In addition, the temperature per luminaire cooling circuit can be controlled to meet more complex control algorithms, such as maintaining the temperature within a narrow specification range, achieving a target temperature, switching between two or more temperatures, and the like.

[0018] For physical protection, the luminaire may have a cover forming the light emission window 51 above the luminaires. This luminaire cover, which can be either a full or segmented cover, can either hermetically seal the luminaires from the environment or allow gas exchange between the environment and the covered luminaires. The latter prevents possible fogging when the ambient temperature and humidity are above the dew point compared to the temperature and humidity under the luminaire cover, and / or vice versa.

[0019] In addition, the lamp cover may have secondary functions such as focusing and / or diffusing the light beam per luminaire and secondary light emission through phosphor, chemiluminescent, and / or fluorescent light emissions. As an example of a secondary function, focusing or diffusing the light beam may be achieved by commercially available optical lenses attached to, embedded in, or otherwise mounted on and / or within the cover. Such lenses may be provided, for example, by Edmund Optics. Another example is the emission of secondary light from the cover upon light excitation from one or more luminaires. This secondary emitted light may be phosphorescent, fluorescent, or chemiluminescent. Phosphorescent light may, for example, be produced by shining a blue light beam onto a phosphor element, as in laser-excited phosphor flashlights from Maxtoch Ltd.is commercially available. Another example is fluorescent secondary light, which can be generated by light excitation of a specific fluorochrome. These secondary lights are used in commercially available optical instruments, e.g., from Olympus. Chemiluminescence, as another example, can be triggered and / or excited by one or more luminaires as a chemical reaction of at least one chemical, e.g., the commercially available luminol from Sigma Aldrich, which can be, for example, embedded, glued, absorbed, adsorbed, or applied by another method onto and / or into the cover.

[0020] The lamp cover is made of a material that can withstand at least one of the sterilization processes described here. Such materials include glass, polycarbonate, and silicone.

[0021] The lights are arranged either in a row, in parallel, or in any other configuration on a light support. The light support can also serve as a coolant barrier.

[0022] The luminaires are arranged so that the luminous flux is at an opening angle of at least 30°, preferably > 90°.

[0023] The lamps have a photon yield of at least 1 µmol / J and preferably > 3 µmol / J, measured with light-sensitive detectors, e.g., a quantum sensor commercially available from Apogee Instruments.

[0024] The luminaires can be dimmed to at least 80% of their maximum power consumption, preferably 0%. Dimming can be controlled by a control loop, either on the luminaire or remotely, for example, by a programmable logic controller (PLC), such as those commercially available from Siemens, or by a potentiometer, such as those commercially available from Arduino. Dimming can be achieved by modulating the luminaire power, e.g., by a continuous voltage input, pulse-width modulation (PWM), electrical resistance, Modbus, and / or DALI signal.

[0025] In another example, the lights can be dimmed individually, per light type or color, in series, in parallel or in any other way.

[0026] Remote control of the lights can be achieved via a wired or wireless connection. Commercially available wireless connections, e.g., from Qualcomm, can be used, using suitable technologies such as radio frequency, radar, optical, microwave, LoRa, Wi-Fi, Bluetooth, LPWAN, cellular networks (e.g., 3G / 4G / 5G), Zigbee, satellite communications (e.g., Iridium), Bluetooth Low Energy (BLE), RFID, or infrared, and / or a mixture of these.

[0027] As another example, the remote control of the lights can be achieved through a series connection, with the information about the light control being passed from light to light and / or from lamp to lamp. This allows the information, especially if it is wired to a first light and / or lamp, to be passed on to the next light and / or lamp. This is particularly advantageous in rooms with a high concentration of sterilizing agents and thus material restrictions regarding cabling and / or cleaning.

[0028] In another example, the lamp body can have an embodiment for detecting the luminous flux of the luminaires. Such sensors are designed as photocells for detecting the reflected light intensity. These sensors are available, for example, from Baumer and can be calibrated to the luminaires and the reflective surface from which the light rays are reflected onto the sensor. With these sensors, the light output of the luminaires, and thus the power consumption, can be controlled in a closed control loop. As an example and secondary use of the sensor, the sensor's measured value can be used to calculate power consumption if it is calibrated with the power output against the measured value of the light sensor at a specific luminaire temperature.

[0029] Another example of a secondary use of the light sensor is detecting the reflection of light from a plant's surface, thus determining the distance between the light and the plant. This secondary function of the light sensor can be performed by a second sensor using a different technology, such as commercially available ultrasonic distance sensors, vision systems, or other optical sensors, such as those offered by Cognex.

[0030] Another example of a secondary use of the light sensor is the detection of the absorption of gaseous chemical components in the atmosphere. Commercially available light sensors, such as those used in analytical chemistry for detecting absorption values ​​in the ultraviolet (UV), visible (VIS), near infrared (NIR), and / or infrared (IR) spectrum, can be used for this purpose. Such absorption spectra can be used, for example, to analyze plant exhaust gases in the gas phase of the environment for volatile organic compounds (VOCs), which are released during stress and / or normal plant growth.

[0031] As another example of the secondary use of the light sensor, the absorption of chemicals in the liquid phase, e.g., in the nutrient solution effluent, can be used to detect excretory chemicals from plant roots and / or to use the absorption spectrum information for closed-loop control of that plant's nutrition.

[0032] As another example of the sensor, the sensor may be a commercially available machine vision system, e.g., such as the Cognex machine vision system, to capture plant growth over time and / or at a specific point in time, with the possibility of analyzing the plant condition, e.g., by means of absolute and / or relative, quantitative and / or qualitative and / or color and / or color change measurements.

[0033] To control the luminaires and their temperatures, the luminaires can be equipped with a temperature sensor, for example, that measures the temperature of the luminaires either individually or for multiple luminaires. This sensor can be used as a closed-loop control system to keep the luminaires within a constant temperature range, follow a temperature program, and / or maintain a constant temperature.

[0034] The cooling system for cooling the luminaire is thermally separated from the ambient cooling by the air conditioning system. The air conditioning system features a coolant duct or other coolant guide. The air conditioning system is also designed as a heat sink.

[0035] The heat sink is shaped to allow ambient moisture to condense on the heat sink. Furthermore, the heat sink is shaped to channel, direct, or otherwise allow the condensate 11 to flow into a condensate collection opening 10.

[0036] In the case of condensation of ambient humidity, the invention can be used in another example to dehumidify the environment.

[0037] In another example, the condensate collection port may include sensors to detect, for example, condensate, dissolved and / or agglomerated chemical components from the gas phase. In an alternative or additional example, the sensors may detect plant exhaust gases in the condensate, e.g., using commercially available detectors such as Shimadzu spectrometers or Abcam enzyme-linked immunosorbent assay (ELISA). In a more specific example, the analysis at the end of the effluent may be performed using commercially available liquid chromatography and / or gas chromatography, both available from Agilent.

[0038] The heat sink can have a specific shape, such as a radiating, star-shaped, or other shape that allows the condensate liquid to flow into a condensate collection opening.

[0039] In another example of the invention, the condensate liquid may be used as a cooling or processing liquid in any other way.

[0040] The heatsink can be either passive or active, such as the one commercially available from Celsia.

[0041] The material of the heat sink can withstand the sterilization processes mentioned here and is made of, for example, aluminum, copper, brass or steel.

[0042] The material of the heat sink, thermal insulation and luminaire housing are made of compatible materials to avoid galvanic corrosion.

[0043] The heat sink may have a condensate collection opening, e.g., a duct, a drain line, a pipe, a pipe with a recess, or similar. The condensate collection opening may have an incline or gradient of at least 1%, preferably > 2%, to allow the condensate to flow to a predefined condensate drain and / or sink.

[0044] Alternatively, the condensate collection opening can be connected to a pump or pump system to actively collect the condensate.

[0045] The heat sink is made of a material that is chemically resistant to the condensate, such as aluminum or steel.

[0046] The coolant may consist of water, water-based mixtures, silicone oil and / or other commercially available coolants and / or mixtures thereof.

[0047] The heat sink can be equipped with a temperature and humidity sensor, such as one commercially available from Testo. This sensor can be either a coupled temperature / humidity sensor or a separate sensor. Using this sensor, the temperature of the coolant can be controlled via a closed control loop depending on the dew point at the given ambient conditions. Specifically, this can either ensure condensation or prevent and overcome condensation. In the second example control option, the heat sink is controlled to cool the environment without condensation cooling and / or condensate collection.

[0048] The coolant in the lamps and the coolant in the heat sink can be the same or different. Furthermore, the coolants can have different or the same temperature.

[0049] The lamp has an electrical connection to supply the lights and / or sensors with electrical energy.

[0050] In a further variant of the invention, the electrical connection can be used as a data transmission line, as used via commercially available Power-over-Ethernet (PoE) protocols or Powerline plugs from Netgear.

[0051] All connections of the luminaire are suitable for use in damp rooms, as defined in the IEC 60529:2019 standard for a protection degree of at least IPx3, preferably better than IPx5.

[0052] All electrical connections 4 of the light source, also called lamp here, support the sterilization processes mentioned here and are made of suitable materials, e.g. acrylate butadiene rubber (ABR), acrylonitrile butadiene styrene (ABS), polyacrylic rubber (ACM), bromoisobutene isoprene rubber (BIIR), butadiene rubber (BR), chloroisobutene isoprene rubber (CIIR), chloroprene rubber (CR), chlorosulfonated polyethylene rubber (CSM), ethylene oxide epichlorohydrin copolymer (ECO), ethylene propylene diene monomer (EPDM), ethylene propylene copolymer (EPM), ethylene vinyl acetate (EVA), tetrafluoroethylene propylene rubber (FEPM), perfluoroelastomer (FFKM), fluoroelastomer (FKM), fluorosilicone rubber (FVMQ), Hydrogenated nitrile rubber (HNBR), Isobutene-isoprene rubber (IIR), Isoprene rubber (IR), Nitrile butadiene rubber (NBR), Nitrile isoprene rubber (NIR), Natural rubber (NR), Polyamide (PA), Polyacrylic acid (PAA), Polyanionic cellulose (PAc),Pyridine butadiene rubber (PBR), polybenzimidazole (PBI), polybutylene terephthalate (PBT), polyethylene (PE), polyether block amide (PEBA), polyetheretherketone (PEEK), polyethyleneimine (PEI), polyethersulfone (PES), polyethylene terephthalate (PET), polycarbonate (PC), polymethacrylate (PMA), polymethyl methacrylate (PMMA), phenylmethyl silicone (PMQ), polyoxymethylene (POM), polypropylene (PP), polyphenylene oxide (PPO), polystyrene (PS), pyridine styrene butadiene rubber (PSBR), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), phenylvinylmethyl silicone (PVMQ), silicone (Q), styrene butadiene rubber (SBR), thermoplastic elastomer (TPE), thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), vinylmethylsilicone (VMQ), and / or mixtures of the polymers mentioned and / or copolymers of the polymers mentioned. The compounds can preferably consist of one or more of the aforementioned materials.

[0053] In another example, the compounds can be made of metals such as aluminum, steel, titanium or their mixtures and / or alloys.

[0054] All of the luminaire's connections are designed to allow for plug-and-play installation with or without additional wires. In one example, the connections are accordion-shaped to allow for bridging the distance between lamps. In another example, connecting wires may be used while the lamp only has female connections. For fluid connections, such as for the coolant, hoses must be used instead of wires. In another example of the connection type, the lamp may have female connectors, male connectors, and / or a mixture of these.

[0055] All connectors allow unidirectional mounting and connection of the lamp in series and / or parallel.

[0056] All connections allow easy replacement of lamps installed in series or parallel.

[0057] All fluid connections can, but do not have to, be designed as self-closing connections, such as those commercially available from Festo.

[0058] The lamp body may, for example, be equipped with fastening elements such as rails, hooks, connectors, magnets, a ferromagnetic body or the like and / or mixtures thereof.

[0059] In another example, the lamp body can be cleaned using clean-in-place (CIP) procedures, as known in pharmaceutical production under Good Manufacturing Practices (GMP), and / or with commercially available cleaning agents such as water, isopropanol, ethanol and / or Bohrer Chemie products and / or mixtures thereof.

[0060] The luminaire is designed to be separated and / or disassembled into at least two parts for recycling purposes.

[0061] As in Fig. 1, the housing 50 is provided with a wall or layer of a heat-insulating material 7, which is arranged opposite the light exit window 51 on the housing 50.

[0062] The light exit window 51 may be made of a transparent material. The rest of the housing may be made of metal and / or plastic. All parts of the housing that come into contact with the environment should preferably be sterilizable. The thermal insulation material does not necessarily have to be such a part of the housing, as in Fig. 1 shown.

[0063] The cooling device 1 and the luminaire section 5 are connected to a heat-conducting material 8 for heat dissipation from the luminaire section 5, which material has a higher thermal conductivity than the thermal insulation material 7 of the housing 50.

[0064] The light source 100 is provided with an air conditioning system 60 arranged on the thermal insulation material 7 of the housing 50. The air conditioning system 60 is the condensate collector 2 and can be an arrangement of cooling fins 9 arranged outside the housing 50 of the light source 100. The air conditioning system 60 thus serves to cool the heat emitted by the light source and / or to reduce the humidity in the enclosed growth chamber.

[0065] The condensate collector 2 for collecting the condensate 11 can be removably attached to the housing 50, e.g. by clamping means such as a clamping rail 12.

[0066] The air conditioning system 60 and the light source 100 are therefore in Fig. 1 connected to a single device.

[0067] The same concept is in Fig. shown. Fig. shows in simplified form a luminaire section 24, which is an LED light panel.

[0068] Fig. Figure 2 also shows a cooling device 25, which is a water cooling plate for cooling the LED. The cooling device 25 is thus located in the immediate vicinity of the lamp support 24. The cooling device 25 is thermally separated from an air conditioning system with a condensate collector 27 and a condensate plate 28. The thermal separation is achieved by an insulating plate 26, which can be part of a housing of the light source, which is Fig. 2 is not shown in detail.

[0069] The device consists of the light source and the air conditioning system, which are connected to each other, preferably permanently. The various elements of the device are provided with coolant 21, 23 and / or an electrical supply 20.

[0070] The condensate 22 accumulating on the surface of the condensate plate 28 can be introduced into the condensate collector 27 and collected. The advantages of using the above-mentioned elements of the device in Fig. 2 have already been explained.

[0071] Fig. Figure 3 shows the general concept of a cultivation system 101 according to the invention. The cultivation system 100 comprises a closed cultivation chamber 70. This closed cultivation chamber 70 may, but need not, have a sterile atmosphere. The closed cultivation chamber 70 may be accessible to the user but may also be operated by robotic systems.

[0072] The enclosed cultivation space 70 could also be a room within a house. It could also be a greenhouse or a shipping container. It is not considered farmland or covered farmland because the environmental conditions in such an environment cannot be adequately controlled.

[0073] The cultivation chamber 70 comprises one or more supports 71 with a cultivation substrate 72. The supports 71 may be racks or frames with flower openings, grooves or the like.

[0074] The growing medium can be soil, cotton, wool, or similar. The substrate can also simply be a grid that holds the plant above a water channel. In the case of fungi, the substrate could be a nutrient solution.

[0075] Below the substrate there is a water channel 73 for supplying the plant roots with water or liquid nutrients, e.g. a water solution with diluted salts.

[0076] Furthermore, Fig. 3 shows the light source 100 and the air conditioning device 70. For data exchange and the control of various elements of the light source 100 in the manner described above, the cultivation system is provided with a control and / or evaluation unit 74, which is connected to the light source via lines 75. The connection can also be wireless.

[0077] The control and / or evaluation device is configured so that the various physical and chemical values ​​determined by measurement can be converted in order to generate further information and / or to control the conditions for the growth of the plants and / or fungi in the closed culture space.

[0078] In addition, the cultivation system 101 is equipped with a power supply device 76 to supply the light source 100 and / or the air conditioning device 70 with power.
