DETAILED DESCRIPTION OF EMBODIMENTS

[0079] Referring to FIG. 1, an exemplary system 100 for controlling the light dependent condition of an organism O, such as a plant, comprises a modulating system 1 and a processing platform 14, which may for example be a computing platform, even a distributed computing platform, that is external from the modulating system 1 and connected thereto by a communication link 15, such as—without limitation—the Internet. The function of the processing platform 14 will be described below in detail in connection with FIGS. 7 and 9.

[0080] The modulating system 1 comprises a light modulation arrangement 2 comprising (exemplarily and without limitation) two light modulation devices 3 and 4. Each of these light modulation devices 3 and 4 is adapted to modulate light by means of a respective light modulating material, e.g. a suitable phosphor. This light modulating material is provided as a respective light modulating surface in the form of a coating 3b or 4b, respectively, being provided on a respective light-transparent carrier sheet 3a or 3b, respectively. Each of these light modulating devices 3 and 4 is designed such that when incoming light 9 falls on its respective light modulating surface/coating 3a or 3b, respectively, the incoming light 9 is passed through the light modulating device and thereby modulated, including by way of wavelength shifting, resulting in outgoing light 10 having an electromagnetic spectrum being different from that of the incoming light 9. The incoming light may particularly be provided either by an artificial light source 5 forming part of the modulating system 1 or by direct or indirect sunlight, or both together. The optional artificial light source 5, which is controlled by the controller device 6 over a respective communication link 7, may specifically comprise at least one of or a combination of at least two of a LED, e.g. an OLED, an incandescent light bulb lamp, a halogen lamp, a fluorescent lamp, a metal halide lamp, a sulfur lamp, a sodium lamp, a neon lamp, an electrodeless lamp.

[0081] The light modulation arrangement 2 is (re)configurable upon receiving a respective configuration signal over a communication link 8, which may particularly be a wireless link, from a controller device 6 also forming part of the modulating system 1. Furthermore, the light modulation arrangement 2 has a housing 2a comprising two slots, each for receiving one of the light modulating devices 3 or 4, respectively. Each of the light modulating devices 3 and 4 is movable in such a translatory way into and out of the respective slot that it can thereby move into or out of, respectively, the light path of the light source 5 directed towards the organism O. Accordingly, the light modulation arrangement 2 is adapted to move each of the light modulating devices 3 and 4, respectively, into or out of the respective slot, depending on the configuration signal it receives from the controller device 6. Particularly, each of the light modulating devices may be selectively moved into or out of its slot or both together may be moved in or out. Thus, the achievable configurations comprise: (a) modulating device 3 in, modulating device 4 out; (b) modulating device 3 out, modulating device 3 in; (c) both modulating devices 3, 4 in; and (d) both modulating devices 3, 4 out.

[0082] The light modulation arrangement 2 is spatially arranged relative to the light source 5 and the organism O such that when the respective light modulating device 3 or 4 moves out of its respective slot, it is moved into the light path from the light source 5 towards the organism O such that the incoming light 9 from the light source 5 falls on the respective modulating device 3 and/or 4 before reaching the organism O as outgoing light 10 after passing through the respective modulating device(s) 3 and/or 4.

[0083] The modulating system 1 may further comprise a sensor system 11 configured to measure, e.g. by means of one or more sensor probes 13, at least one environmental condition to which the organism O is exposed, and to output sensor data representing one or more respective measurement results. The sensor system may particularly measure at least one or a combination of at least two of the following environmental conditions to which the organism O is exposed: temperature, intensity or spectrum of electromagnetic radiation or a shift of such spectrum relative to a preceding reference point in time or time frame, humidity, moisture of soil, available nutrition in the soil, air pressure, sound, concentration of carbon dioxide and/or oxygen, wind or other airflows, electrical and/or magnetic fields, gravitational field, chemical composition of environment and/or soil, pH level of soil, soil reflectivity, topography of the environment.

[0084] The sensor data may further represent at least one of or a combination of at least two of the following quantities relating to a state, preferably a growth state, of said organism and to output the corresponding measurement results as part of the sensor data: growth rate of the organism as a whole or one or more specific parts thereof, an amount of organic matter, biological activity, biomass, morphology, color of organism or one or more specific parts thereof, diseases, kind and/or level of present pathogens, and/or, if the quantity to be measured relates specifically to one or more plants: plant size, leaf size, stem size, size or ripening state or other appearance or property of at least one fruit, a level of performed photosynthesis, motion of one or more plant parts, weed occurrence, salinity, leaf area, count, color and/or size, leaf color, N-Index.

[0085] Furthermore, the sensor system 11 may comprise a location determination function or module 11b, for example for satellite-based location determination using a global location determination system such as GPS, GALILEO, GLONASS etc., and may thus have a corresponding antenna 11c. The sensor system 11 is connected to the controller device 6 by means of a communication link 12, which may particularly be a wireline or a wireless link (e.g. WLAN based), in order to be able to provide sensor data to the controller device 6 and optionally also receive control information, such as control commands, in the opposite direction. The controller device 6 further comprises a man-machine-interface 6a designed such as to allow for communicating information to a human user and to receive user inputs, for example inputs defining the kind of organism, a desired growth effect, location related specifics such as, for example, the geographical orientation of the greenhouse in which the organism is located, or other information. The information communicated by the man-machine-interface 6e to the user may particularly comprise instructions for operating the modulation system 1 or other equipment having an effect on the growth of the organism, such as heating, shading etc.

[0086] Optionally, one or more, if not all, of the components of the modulation system 1 or of the modulation system 1 as a whole, may be provided with one or more mounting structures for mounting the respective one or more components or the modulation system 1 as a whole to a support structure, which may particularly be or form a part of an irrigation structure or a vehicle. In this way, the respective component(s) or system may easily be fixed to an existing respective support structure and in the case of vehicle may be movable relative to the organism O or plurality of organisms to be treated by means of the modulation system 1, particularly by its light modulation arrangement 2. By way of example, and without limitation, the light modulation arrangement 2 may comprise a support structure 2b, and the sensor system 11 may comprise a respective support structure 11a provided at their respective outer surface.

[0087] In order to demonstrate the impact of the light modulation on the growth of organism O, one or more reference organisms O.sub.R of the same type as organism O may be treated exactly the same as organism O, however with the exception that O.sub.R is not exposed to the modulated light delivered by the light modulation arrangement 2 of the light modulating system 1.

[0088] Referring to FIG. 2, which shows a system for controlling the light-dependent condition of an organism O according to an exemplary second embodiment 200 of the present invention, the system and its function are similar to that of the system of FIG. 1, however with the exception of the different light modulation arrangement 2, which will now be described in more detail.

[0089] According to this embodiment, the light modulation arrangement 2 comprises a plurality of artificial light sources 5 serving as light modulation devices. In the present illustrative example, the light modulation arrangement 2 comprises two artificial light sources 5a and 5b. Each of the two light sources 5a and 5b, each of which may for example be a light-emitting diode (LED) or even a classical incandescent lightbulb, has a respective coating 30a or 30b made of a respective light modulating material such that at least some light emitted from the respective light source 5a or 5b passes through the respective coating 30a or 30b and is thereby modulated. The light modulating materials of the two light sources are different in such a way that even when the light sources themselves are of the same type, the outgoing light 10a of light source 5a differs in its spectral properties from the outgoing light 10b of light source 5b.

[0090] The light modulation arrangement 2 is connected to the controller device 6 by means of a communication link 8, which serves at the same time as communication link to the individual artificial light sources 5a and 5b. For example, this communication link 8 may be implemented by means of a bus and the artificial light sources 5a and 5b may then have a corresponding connection and control units (not drawn) for enabling the connection of the respective light source 5a, 5b to the bus. The controller device 6 is configured to selectively activate and/or deactivate the light sources 5a, 5b by means of a respective control signal sent over the communication link 7, 8. Particularly, this allows for four different configurations in the form of different activation states, namely: (a) light source 5a on, light source 5b off; (b) light source 5a off, light source 5b on; (c) both light sources 5a, 5b on; (d) both light sources 5a, 5b off. In this way, the light modulation arrangement 2 may be (re-)configured through the controller device 6.

[0091] Referring to FIG. 3, which shows a system for controlling the light-dependent condition of an organism O according to an exemplary third embodiment 300 of the present invention, the system and its function are again similar to that of the systems of FIG. 1 and FIG. 2, however with the exception of a yet further different light modulation arrangement 2, which will now be described in more detail.

[0092] The light modulation arrangement 2 comprises one reconfigurable light modulation device comprising a container 40 having a hollow channel 40a for receiving a fluid comprising light modulating material, for example a liquid containing light modulating particles. The container 40 is transparent or at least semi-transparent to the light of light source 5, such that the light can pass through both the container 40 and the light modulating fluid in its channel 40a to transform ingoing light 9 into modulated outgoing light 10, to which the organism is then being exposed.

[0093] Furthermore, the light modulation arrangement 2 comprises a composition source for supplying one or more different compositions comprising at least one light modulating material to the channel 40a of the container 40. The composition source, in turn, comprises a pump 20a and a set of tanks 20b, 20c, 20d and 20e for containing a respective type of light modulating fluid. Particularly, tanks 20b, 20c, 20d may each serve to store a different type of light modulating fluid, e.g. a fluid composition comprising ruby in tank 20b, a further fluid composition comprising MTO in tank 20c, and a yet further fluid composition comprising YMT in tank 20d. The pump 20a is configured to selectively pump a respective fluid composition from a selected one of the tanks 20b, 20c, 20d into the channel 40a of the container 40. Furthermore, it may be configured to pump a selected mix of at least two of the fluid compositions through respective pipes from the respective tanks 20b, 20c, 20d into the channel 40a. To that purpose, the pump 20a may comprise a set of one or more valves (not drawn). In this way, the light modulating property of the light modulating arrangement 2 may be selectively configured under the control of the controller device 6, which is adapted to communicate corresponding control information, e.g. configuration commands, over the communication link 8 to the light modulation arrangement 2, by selectively modifying the filling of channel 40a with one or more of the light modulating compositions from tanks 20b, 20c, 20d and optionally also from a further tank 20e. Specifically, the further tank 20e may either be used as a waste tank to collect fluid returning from the container 40, i.e. its channel 40a, or as a further storage tank for yet another light modulating fluid composition, e.g. a composition comprising CAZO as a light modulating material.

[0094] Particularly, Container 40 may be further configured as a cover, a roof (e.g. a corrugated roof or a roof tile), a wall or a floor, or an element for building one of the foregoing, of a host compartment for hosting said organism (such as a greenhouse, a planter or a stable). In some variants, the container may be made of a material comprising or consisting of polycarbonate, which is a particularly robust, low weight and light transparent material and thus a preferable material for building the container or parts thereof.

[0095] Referring to FIGS. 4A and 4B, Channel 40a of container 40 may particularly be configured as a set of individual channels (cf. FIG. 4A) or as a single channel, which may particularly be winding through the body of container 40 (cf. FIG. 4B) in order to optimize the spatial coverage of the container's overall light modulating effect. While the embodiment according to FIG. 4A has the advantage that different fluid compositions from different tanks may be guided separately and without mixing among each other through the container 40, the embodiment according to FIG. 4B allows for mixing such different compositions, which may particularly be used for achieving an even higher spectral homogeneity across the outgoing light 10 as compared to the solution of FIG. 4A.

[0096] Referring to FIG. 5, which shows a system for controlling the light-dependent condition of an organism O according to an exemplary fourth embodiment 400 of the present invention, the system and its function are again similar to that of the systems of FIGS. 1 to 4, however with the exception of a yet further different light modulation arrangement 2, which will now be described in more detail.

[0097] The system according to this fourth embodiment 400 may particularly be considered a modification of the system 300 illustrated in FIG. 3, wherein instead of container 40 an applicator 50 is provided to directly apply the selected one or more fluid light modulating compositions to organism O. Particularly the fluid composition may be applied selectively to different parts of the organism O. For example, if organism O is a plant, the fluid composition may be applied selectively the stem, the leaves or needles, the soil, the flowers, the fruits or other parts of the plant, as applicable and desired. This may particularly be useful, if enhancement of not only an overall growth of organism O, but rather enhancement of one or more individual growth aspects, e.g. leaf growth or fruit growth, is desired. Otherwise, system 400 and its function is similar to system 300 and its function, respectively.

[0098] Furthermore, a system for controlling the light-dependent condition of an organism O according to the present invention may comprise two or more light modulating arrangements 2 according to different embodiments, in particular as described above in connection with exemplary systems 100 to 400. For example, and without limitation, the light modulation arrangements of system 200 and system 300 or particularly 400 may be combined, particularly either in parallel, such that either one of the light modulating arrangements may be selected for applying light to a particular organism O, or cumulatively, such that the light to which the organism O is being exposed is modulated by two or more of these different light modulating arrangements 2 in order to achieve a combined light modulation effect.

[0099] Referring to FIGS. 6A-6D, different light modulating materials, which illustrate different spectra of ingoing and outgoing light, may be used according to preferred embodiments of the present invention and specifically with each of the systems described herein, including in particular systems 100 through 400. Specifically, FIGS. 6A-6D show respective intensity spectra (each normed to a maximum intensity value of 1) of incoming light 9 (dashed line) and outgoing light 10 (solid line) for four exemplary light-modulating phosphors, namely AL.sub.2O.sub.3Cr.sup.3+ (ruby, FIG. 6A), Mg.sub.2TiO.sub.4:Mn.sup.4+ (MTO, FIG. 6B), Y.sub.2MgTiO.sub.6:Mn.sup.4+ (YMT, FIG. 6C), and Ca.sub.3Al.sub.4ZnO.sub.10 (CAZO, FIG. 6D). Specifically, in FIG. 6D the emission spectra relating to the two different excitation wavelengths 320 nm and 460 nm, respectively, are drawn individually for the purpose of also illustrating the dependence on the excitation wavelength. All four of these light modulating materials show a Stokes shift, i.e. a shift from incoming shorter wavelengths to outgoing longer wavelengths, the latter being focused particularly in a narrower wavelength range in the vicinity of 700 nm.

[0100] Referring to FIG. 7, an exemplary method 500 of determining a configuration of a modulating system according to the present invention, e.g. according to any one of FIGS. 1 to 5 (being referred to hereinafter), comprises receiving 510 input information comprising sensor data representing at least one current environmental condition to which the organism O is currently being exposed (current sensor data) and scenario data defining the kind of the organism O (e.g. “strawberry plant”) and at least one to-be-optimized growth effect of said organism O. The method further comprises processing 520 the input information by using a machine-learning-based process to derive therefrom control information for controlling the light modulation arrangement 2 of the modulating system 1.

[0101] The processing 520 may particularly be performed by the controller device 6 of the modulating system 1 or instead by the external processing platform 14. Typically, the other process steps of method 500 will be performed by the controller device 600, although other configurations are possible as well. In particular, the processing 520 may involve looking up predefined configuration data in a database, such as a lookup table, using the input information as search parameter(s) and retrieving configuration information defining a particular configuration of the light modulation arrangement 2 of the modulating system 1 in return. The content of the database, e.g. the lookup table, or the data retrieval process itself, or both, may be dynamic in such a way, that it is/they are regularly or continuously redefined based on the results of a machine-learning-based updating process, which may particularly be a supervised learning process using historical sensor data of previous measurements or iterations as input representing supervising information.

[0102] Method 500 further comprises outputting 530 the derived control information to the light modulation arrangement 2, in order to configure it accordingly. In addition, application data may be output, which represents at least one of or a combination of at least two of the following: (i) a degree, a duration, an amount, or a kind of the processing having occurred in relation to method 500, e.g. specifically in relation to processing 520; (ii) at least one characteristic of the related input information for such processing, e.g. the kind of organism O, or the desired growth effect, or both. The application information may particularly be used to determine indication of use for method 500, which may for example be used to determine based thereon a fee to be paid by a respective user.

[0103] Moreover, method 500 comprises storing the scenario data, the sensor data and/or the derived control information, at least in parts, to a data storage, which may particularly be implemented as a storage within controller device 6 or as a storage being external but assigned thereto. Storing the data does not only provide the advantage of making this stored information available for later review (e.g. for control purposes), but also of enabling a use of the stored information as supervising information serving as input to the machine learning process. Particularly, a comparison of the current sensor data with corresponding historical sensor data may be used to determine actual growth effects having occurred at the organism O, wherein the result of this comparison may be correlated with the corresponding control information and/or scenario data for the purpose of determining their impact on the achieved growth effect.

[0104] Referring to FIG. 8, preferred combinations of selected types of organisms, which may be treated with the system for controlling the light-dependent condition of an organism of the present invention for the purpose of achieving one or more enhanced growth effects are shown in relation to preferred light modulating materials to be used for the treatment of such respective organisms. Specifically, the table of FIG. 8 illustrates that some light-modulating materials are more suitable for treatment of a given organism than others and that there are also preferable ways of application (here exemplarily (i) “sheet”, which relates for example to the embodiments of FIGS. 1 and 3, and (ii) “spray”, which relates for example to the embodiment of FIG. 4). Accordingly, the systems and methods presented herein are particularly suitable to reflect these differences and allow for an optimal (re-)configuration of the respective light modulation arrangement in view of the particular needs of the organism to be treated.

[0105] Referring to FIG. 9, an exemplary method of determining a suitable light modulating material to be used in a light modulating system according to the present invention, e.g. according to any one of FIGS. 1 to 5, may be implemented by means of an application running on a local or mobile computer, such as for example a desktop, laptop or tablet computer, or even a smart phone. Specifically, according to some variants, the computer may be at the same time the controller device 6, e.g. of system 100, 300 or 400.

[0106] For the purpose of illustration, the following description of the method of FIG. 9 relates to a situation, where a farmer or “grower” intends to determine, with the help of an application running on his local or mobile computer, a suitable light modulating material, or in other words a suitable configuration of his light modulating system according to the present invention, for a particular type of crop in the grower's greenhouse in order to optimize its growth. In this example, natural sunlight is to be used as a light source for the incoming light 9 instead of or at least in addition to artificial light sources, like those described above.

[0107] A first process 610 of the exemplary method comprises starting the application or a specific feature within the application that relates to determining a suitable light modulating material to be used in a given, i.e. the grower's, light modulating system. In a further process 620, the location of the grower, i.e. the computer or the greenhouse, is being determined using a location determination technology, such as for example GPS, with the help of a respective location determination module within the computer or anywhere else within the overall system.

[0108] In a further process 630, the computer attempts to establish an Internet connection, if not already present, and if such connection is successfully established (process 640—yes), the application continues in process 650 to access and receive spectral data representing one or more characteristic, location-dependent properties of the sunlight spectrum related to the specific location identified in process 620 over the Internet from a respective source, such as a database provided on a central external server, e.g. by NASA or ESA (American and European Space agencies, respectively) or other organizations providing such information to the public or to customers on a contract basis. Otherwise (process 640—no), process 650 is skipped.

[0109] The application then requests in process 660, over a man-machine-interface (MMI) of the computer, e.g. MMI 6a, an input providing further details on the greenhouse. In a subsequent process 670, the application receives the corresponding inputs provided by a user through the man-machine-interface, e.g. details on the provider and type of the greenhouse, or the material, especially roof and sidewall material, used to construct the greenhouse.

[0110] In process 680, and estimation of the specific sunlight spectrum and (esp. maximum or average or as a function of time) intensity available within the greenhouse is calculated based on the information provided in process 650, if applicable, and in process 670. The spectrum in the greenhouse might particularly depend on the geolocation of the greenhouse, its orientation, an angle of the roof or walls, e.g. relative to the surface of the earth at the location, or the material of the roof and walls, respectively. Due to the variable path of the sun in the sky (daily and over the year), the spectrum, respectively at least one characteristic property thereof, will preferably be determined as a function of time.

[0111] In addition, the application requests in process 690 further input, namely scenario data including a selection of the type of crop to be treated in the greenhouse with light to be modulated by the light modulating material to be selected with the help of the application, and optionally also at least one to-be-optimized growth effect of said crop or parts thereof. Such input scenario data is received in process 700.

[0112] Then, in process 710, the best modulating material under the given conditions, namely the determined available spectrum in the greenhouse and the scenario data, is being determined by correlating the needs of the given crop to the spectrum in the greenhouse and the particular properties of various available light modulating materials. Specifically, process 710 may be similar to the corresponding process that 520 of method 500 of FIG. 7, and may optionally also form part of a machine-learning-based process in a similar manner as described in connection with FIG. 7. In the final step 720, the determined result identifying the determined optimal modulating material (or equivalently, the optimal configuration of the grower's light modulating system being available in the greenhouse) is output, via the man-machine-interface, e.g. MMI 6a in order to enable the grower to configure his system accordingly. Alternatively or cumulatively, the output may be directly used to control the light modulation arrangement 2 of the system in order to automatically (re-)configure it according to the determined optimal configuration.
