Description

Agricultural lighting device, system and method

Technical Field

The invention relates to the technical field of biological lighting systems, in particular to an agricultural lighting device, an agricultural lighting system and an agricultural lighting method.

Background

The plant factory combines modern industry, biotechnology, nutrient solution cultivation, information technology and the like, carries out high-precision control on environmental factors in facilities, has the advantages of full sealing, low requirements on surrounding environment, shortening the plant harvesting period, saving water and fertilizer, no pesticide production, no waste discharge and the like, and has the unit land utilization efficiency 40-108 times of that of open field production, wherein the intelligent artificial light source and the light environment regulation play a decisive role in the production efficiency. Light is used as an important physical environment factor, and plays a key role in regulating and controlling the growth and development of plants and the metabolism of substances. One of the main characteristics of the plant factory is a fully artificial light source and the intelligent regulation of the light environment is realized, which is a common consensus in the industry. However, the existing plant light lamp can realize continuous output of crops all the year round through manual control of illumination, watering, fertilization and the like. However, the existing plant light lamps are fixedly arranged, and the illumination adjustment of plants is realized by selectively turning on and off the plant light lamps. The plant light lamps needed in the method are more in number and higher in cost, and in addition, the illumination of plants is not flexibly adjusted, so that the adjustment operation is troublesome. Meanwhile, the electricity charge in the production cost of the plant factory is about 30%, and if no cheap power supply and high-efficiency artificial lamplight are adopted to reduce the production cost, the plant factory is not attractive to farmers. Thus, the development of a resource-saving light source is a necessary requirement for the construction of plant factories.

For example, chinese patent publication No. CN111174153a discloses a sports type plant light supplementing device, which includes a light supplementing unit and a guide rail unit, wherein the light supplementing unit includes a movable bracket, a light supplementing lamp mounting frame disposed on the movable bracket, and a plurality of plant light supplementing lamps disposed on the light supplementing lamp mounting frame; the guide rail unit comprises a fixed bracket and a guide rail connected with the fixed bracket; the movable support is movably connected with the guide rail; the movable support is provided with side support legs respectively positioned at two sides of the guide rail, the tail ends of the side support legs are rotatably connected with travelling wheels, and the travelling wheels are in butt joint with the guide rail; one of the travelling wheels is connected with a driving device. Therefore, the number of the required plant light lamps is reduced, the cost is reduced, and the plant illumination is flexibly and conveniently adjusted. However, the present inventors have found that the present invention still has the following technical disadvantages: the light source (such as an LED) used in the invention is prone to form white light by mixing a plurality of kinds of fluorescent powder in a certain proportion, the white light LED is matched with fluorescent conversion devices with different wavelengths to work when light is emitted, the power consumption is high, the light conversion efficiency is low, the number of required LED lamps is large, the energy consumption of the whole illumination system is high, and the light utilization rate of the LED of the illumination system is not high. Therefore, how to meet the illumination requirements of animals and plants under the limited light source, thereby achieving the purposes of reducing the investment of fixed equipment (illumination system) and reducing the power consumption and the energy consumption expenditure of daily operation are the technical starting points of the invention. There is a need for improvements that address the deficiencies of the prior art.

Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides an agricultural lighting system. The agricultural lighting system at least comprises a light source part, a guide rail part and a control part.

The light source part is configured to be capable of providing high-energy illumination to animals and plants in the planting/breeding area;

a guide rail portion for connecting the light source portion so that the light source portion can move at least with the guide rail portion;

a control section for controlling at least the movement of the rail section;

under the condition that the control part can acquire the corresponding illumination demands of the animals and the plants, the control part is configured to provide illumination for the animals and the plants in a narrow-band mode based on the illumination demands of the animals and the plants so as to reduce the electric energy consumption of the illumination system while meeting the illumination demands required by the growth of the animals and the plants.

According to a preferred embodiment, the light source section includes at least a monochromatic light lamp unit and a light distribution structure unit. The monochromatic light unit can emit high-energy monochromatic light, and the light distribution structure unit can enable the monochromatic light to be converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants. Because for plants receiving photons with the same energy, the growth promoting effect of the plants brought by short-time high light intensity is better than the growth promoting effect of the plants brought by long-time low light intensity. Therefore, the light distribution structure unit can enable the monochromatic light to be converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants. Under the condition of the same energy consumption, compared with the average stepwise arrangement of a plurality of light sources, the light sources (namely the monochromatic light units) are intensively arranged and projected on animals and plants in a smaller range, and the illumination mode has better growth promotion effect on the animals and plants. By means of the configuration mode, the light source part only adopts a small number of LED lamps, then light emitted by the LED lamps of the monochromatic light unit is converged to the light emitting structure through the light distribution structure unit (such as a focusing lens, a Fresnel lens and the like), and is projected to animals and plants through the light emitting structure framework, so that the light emitted by the small number of LED lamps can be converged to form a narrow-band light band through the light source part to obviously enhance the light intensity of emergent light, and the light band with higher light intensity is projected to the animals and plants, and therefore the power consumption of a lighting system/device/equipment can be obviously reduced and the electric energy utilization efficiency of the light source part can be improved to a certain extent while the illumination required by the growth of the animals and plants is met, namely, the technical effect of obviously saving energy is achieved.

According to a preferred embodiment, the guide rail portion is configured such that the light source portion moves along with the guide rail portion and irradiates the animals and plants with light generated by the light source portion in a scanning manner. The light source part can rotate in a static state or along the axial direction of the guide rail part, so that the incidence direction of the light emitted by the light source part to the animals and the plants is continuously changed, and the irradiation dead angle generated when the light generated by the light source part is emitted to the animals and the plants is reduced.

According to a preferred embodiment, the light source part further includes a light feedback analysis unit, and the light feedback analysis unit includes at least a light emitting panel subunit and a light sensor disposed on a light receiving surface of the light emitting panel subunit. In the case that the light receiving surface of the light emitting plate subunit is coated with the fluorescent powder, the light emitting plate subunit is configured to be placed on the light receiving surface side of the plant root, so that the light generated by the light source part and/or leaked by natural light passing through the plant leaves is fully utilized to excite the fluorescent powder on the light receiving surface side of the light emitting plate subunit to emit light required by the plant, and the light can be irradiated to the plant. By the arrangement mode, the side, facing the plants, of the monochromatic light unit can be coated with fluorescent powder, so that the fluorescent powder on the monochromatic light unit can be excited again by the light emitted from the light-emitting plate subunit to the monochromatic light unit to generate light emitted to the plants, and the utilization rate of the light emitted by the monochromatic light is improved.

According to a preferred embodiment, the light feedback analysis unit further comprises a light analysis statistics subunit. The light analysis and statistics subunit can record the photon number captured by one side of the light receiving surface of the light emitting board subunit and/or the energy excited by the fluorescent powder by the light sensor, can analyze and obtain growth vigor information of the plant based on the photon number and/or the energy excited by the fluorescent powder, and can send the photon number and/or the energy excited by the fluorescent powder to the control module so that the control part can adjust illumination provided for the plant.

According to a preferred embodiment, the control module further comprises a database recipe unit. In the case that the database recipe unit is capable of obtaining the energy of the excited fluorescent powder sent by the light analysis statistics subunit, the database recipe unit is configured to form and/or update a light meal database matching the illumination requirement of the plant based on the energy of the excited fluorescent powder.

According to a preferred embodiment, the light receiving surface of the light emitting panel subunit comprises a first region. The concentration of the fluorescent powder in the first area can be gradually reduced or increased along the radial direction and the outer direction of the plant stem part by taking the plant stem part as the center, so that the light analysis and statistics subunit can at least obtain the growth condition of the plant leaf based on the change analysis of the photon quantity captured by one side of the light receiving surface of the light emitting plate subunit or the energy excited by the fluorescent powder, and then can analyze and obtain factors influencing the plant growth so as to optimize the light meal database.

For example, since the concentration of the phosphor in the first region is decreased radially outward along the stem of the plant centering around the stem of the plant, it may be divided into a first annular band, a second annular band, a third annular band, and so on. Preferably, the width of each endless belt is uniform. Thus, when the incident angle of the light emitted by the monochromatic light unit to the plant changes, the light analysis and statistics subunit integrated with or arranged on the light receiving surface of the light emitting plate subunit can judge or determine the specific growth condition of the plant leaf through the photons which are received by the different annular bands and are missing from the plant leaf (for example, the leaf at the top is rare, or the leaf at the root is rare, or the leaf at one side or all leaves at one side is less than the normal level of the plant).

Particularly preferably, the light analysis and statistics subunit is capable of determining from which part of the plant the missing light is incident or missing into the first region, based on the trend of the energy excited by the phosphor in each of the annular bands during the movement of the missing light within the first region.

According to a preferred embodiment, the light receiving surface of the light emitting board subunit further includes a second region, wherein the fluorescent powder of the second region is coated on the light receiving surface of the light emitting board subunit in the second region in a manner of same concentration, so that the fluorescent powder of the second region can be directly excited by the light emitted by the monochromatic light unit and/or natural light which is not blocked by plants to generate light which can be used for plant growth, and the side of the light source part facing the plants can be coated with the fluorescent powder, so that the fluorescent powder on the light source part can be excited again by the light emitted from the light emitting board subunit to the light source part to generate the light which is emitted to the plants.

According to a preferred embodiment, an agricultural lighting device comprises:

an image acquisition part configured to be capable of acquiring at least an image and/or video of an animal and/or plant in a specified area and transmitting the image and/or video to a control part. The control part can analyze and identify the basic data information of the animals and/or plants according to the images and/or videos of the animals and/or plants acquired by the image acquisition part, and control the light source part to provide the animals and/or plants with light meal which meets the requirement of the basic data information according to the basic data information.

According to a preferred embodiment, an agricultural lighting method is: the light source part can provide high-energy illumination for animals and plants in the planting/breeding area; a guide rail portion for connecting the light source portion so that the light source portion can move at least with the guide rail portion; a control part for controlling the movement of the guide rail part; the control part provides illumination to the animals and plants in a narrow-band mode based on the illumination requirements of the animals and plants so as to reduce the electric energy consumption of the illumination system while meeting the illumination requirements required by the growth of the animals and plants.

Detailed Description

The following detailed description refers to the accompanying drawings.

Fig. 1 and 2 show an agricultural lighting system. The agricultural lighting system comprises at least a light source section 1, a rail section 2 and a control section 3.

The light source section 1 is configured to be capable of providing high-energy illumination to animals and plants within a planting/breeding area;

the guide rail portion 2 is used to connect the light source portion 1 so that the light source portion 1 can move at least along with the guide rail portion 2.

The control unit 3 can be used at least for controlling the movement of the rail unit 2.

In case the control part 3 is capable of obtaining the illumination requirements of the animals and plants, the control part 3 is configured to be capable of providing illumination to the animals and plants in a narrowband manner based on the illumination requirements of the animals and plants so as to reduce the power consumption of the illumination system while meeting the illumination requirements required for the growth of the animals and plants.

Particularly preferably, the light source section 1 includes at least one monochromatic light lamp unit 101. Preferably, the monochromatic light lamp unit 101 may employ an LED lamp. Under the condition that the control part 3 can acquire the requirements of different plants corresponding to the illumination part and different growth stages of the same plant on the light formula, the control part 3 can use the LED core light technology to combine the lights with different colors such as red, orange, yellow, green, blue, purple and the like in different proportions and intensity, thereby not only meeting the energy requirement of photosynthesis of the plants, but also being suitable for the accurate control of the growth and development of the plants, saving energy sources and cost in production, and further preparing the most suitable light formula.

According to a preferred embodiment, the light source section 1 includes at least: a monochromatic light lamp unit 101 and a light distribution structure unit 102. The monochromatic light unit can emit high-energy monochromatic light. The light distribution structure unit 102 can make the monochromatic light converged into a narrow band with a smaller emergent range and intensively emitted to the animals and plants.

For plants receiving photons of equal energy, the growth promoting effect of the short-time high light intensity on the plants is better than the growth promoting effect of the long-time low light intensity on the plants. Particularly preferably, the light distribution structure unit 102 can concentrate the monochromatic light into a narrow band with a smaller emission range and concentrate the monochromatic light to the animals and plants. Under the condition of the same energy consumption, compared with the average stepwise arrangement of a plurality of light sources, the plurality of light sources (namely the monochromatic light lamp units 101) are intensively arranged and projected on animals and plants in a smaller range, and the illumination mode has better growth promotion effect on the animals and plants.

Preferably, the mono-color lamp unit 101 may be an LED lamp manufactured to emit light vertically downward. Preferably, the LED lamp of the mono-color lamp unit 101 may also be manufactured as an inter-plant light supplement lamp that emits light at three hundred sixty degrees close to the plant.

Preferably, the light distribution structure unit 102 may include, but is not limited to: focusing lenses, fresnel lenses, light extraction structures, etc. Preferably, the light distribution structure unit 102 can collect the monochromatic light generated by the monochromatic light lamp unit 101 in a smaller light emitting structure and emit the collected illumination with higher energy to the area where animals and plants are located in a narrow-band mode.

Preferably, the light emitting structure may be in the shape of an elongated narrow strip or slit. Preferably, the light emitting structure may also be circular arc or ring. For example, the light distribution structure unit 102 may collect the light emitted by the LED lamp of the monochromatic light lamp unit 101 to the light emitting structure through a focusing lens, a fresnel lens, and the like, and project the light to the animals and plants through the light emitting structure. Preferably, the light emitting structure may be in a strip shape or a linear shape.

Preferably, the shape of the light emitting structure can be flexibly set according to the actual illumination requirement. By this arrangement, the light source part 1 adopts only a small number of LED lamps, and then the light emitted from the LED lamps of the monochromatic light unit 101 is converged to the light emitting structure by the light distribution structure unit 102 (for example, a focusing lens, a fresnel lens, etc.), and is projected to the animals and plants by the light emitting structure, so that the light emitted from the small number of LED lamps can be converged to a narrow band shape by the light source part 1 to remarkably enhance the light intensity of the emitted light, and the light band with higher light intensity is projected to the animals and plants, thereby satisfying the illumination required for the growth of the animals and plants, while also remarkably reducing the power consumption of the lighting system/device/apparatus and improving the electric energy utilization efficiency of the light source part 1 to a certain extent, that is, achieving the technical effect of remarkably saving energy.

According to a preferred embodiment, the guide rail part 2 is configured such that the light source part 1 is moved along with the guide rail part 2 and the animal and plant are irradiated with the light generated by the light source part 1 in a scanning manner. The light source part 1 can rotate in a static state or along the axial direction of the guide rail part 2, so that the incidence direction of the light emitted by the light source part 1 to the animals and plants is continuously changed, and the irradiation dead angle generated when the light generated by the light source part 1 is emitted to the animals and plants is reduced.

Preferably, the rail portion 2 may include a rail unit and a lifting unit. Preferably, the rail unit is capable of horizontally moving by acquiring a control signal from the control unit 3.

It is particularly preferred that the rail unit is rotatable along a point inside or outside the rail unit. Preferably, the lifting unit is capable of lifting the rail unit in a vertical direction.

It is particularly preferred that the monochromatic light unit 101 and the rail unit are rotatably connected by a rotation unit.

It is particularly preferable that the turning unit is capable of acquiring the control signal transmitted to the turning unit by the control section 3 and controlling the mono-color lamp unit 101 to hold or adjust the direction of the light emitting structure of the mono-color lamp unit 101 in a static manner or in a manner of turning in the axial direction of the rail unit. Through this configuration mode, the emergent light direction of emergent light that monochromatic light unit 101 sent can be adjusted according to the demand that animal and plant actually grows, and the unit that rotates promptly can make the emergent light that monochromatic light unit 101 sent shoot to the plant with different incident angles to reduce the dead angle that emergent light irradiated the plant. For example, when the rail unit makes the monochromatic light unit 101 reciprocate or rotate longitudinally along a plane (e.g., a horizontal plane), the monochromatic light unit 101 can rotate clockwise or counterclockwise along the axial direction of the rail unit under the driving of the rotating unit, so that the light emitted by the monochromatic light unit 101 to the same area or the same plant can irradiate the same area or the same plant at different incident angles.

For another example, when the guide rail unit makes the monochromatic light unit 101 reciprocate or rotate longitudinally along a plane (e.g., a horizontal plane), the direction pointed by the monochromatic light unit 101 may form a certain included angle with the horizontal plane, and at the same time, the monochromatic light unit 101 may be driven by the rotating unit to perform horizontal scanning with the rotating unit as a center of a circle, so that the light rays emitted by the monochromatic light unit 101 to the same area or the same plant may irradiate the same area or the same plant at different incident angles.

Preferably, the number of the rail portions 2 may be plural. Preferably, the rail units of at least two rail portions 2 can be moved in opposite directions in the same plane or in different planes. By this arrangement, the rail units of at least two rail portions 2 can be made to drive the corresponding monochromatic light lamp units 101 to irradiate different sides of the plants, so that the plants can be irradiated from different directions or sides, and the irradiation dead angle of illumination can be further reduced.

For example, in the case where the light source section 1 moves in a plane (for example, horizontally reciprocating longitudinal movement or horizontally rotating movement) along with the rail section 2, the monochromatic light lamp units 101 corresponding to the different rail sections 2 may move toward each other or away from each other. Preferably, the light source part 1 can arrange the monochromatic light units 101 in multiple directions according to the plant growth requirement, so that the illumination intensity, the illumination direction, the spectrum composition and the like can reach the optimal illumination environment required by the plant.

Preferably, at least two light source units 1 may be connected to the guide rail in a fixed manner (i.e. the direction of the outgoing light remains unchanged), while the guide rail rotates at a fixed point of the animal and plant area, while the two guide rails connected to the light source units 1 are in opposite directions.

Particularly preferably, the light source unit 1 is connected to the rail unit by a rotation unit so that the light source unit 1 can rotate at least about the axial direction of the rail to adjust the angle of the emitted light to the animals and plants, so as to reduce the irradiation dead angle of the light source unit 1.

Preferably, a single or a small number of light sources provide illumination to the animals and plants in a scanning manner. Preferably, the rail unit is movable in a circular motion. Preferably, the rail unit is movable in a zigzag shape. Preferably, the light source section 1 may be disposed at or near the ground. Preferably, the manner of large-scale illumination of a single light source or a small number of light sources may include: the light source performs scanning in a mobile scanning or fixed (non-mobile) manner.

Preferably, the light source section 1 can make the illumination intensity of the distal end and the proximal end of the rail unit uniform or approximately uniform at the time of the moving scan.

Preferably, at least two light source units 1 can be driven by the guide rail unit 2 to perform scanning in opposite directions. Preferably, the light source section 1 itself may also realize pitch and/or roll under the cooperation of the rail section 2.

Preferably, the outgoing light of the light source section 1 may also be designed by light distribution such that the outgoing light is not in a circular band shape, but in a circular shape, a rectangular shape, or the like, for example. For example, the same light source is provided with an asymmetric lens, and then the near, middle and far three areas of the area where the plants are located can be managed; after the different light sources are matched with the asymmetric lenses, the near, middle and far areas of the area where the plants are can be divided into three areas.

By this arrangement, compared with a uniform static light source, the light source part 1 with narrow band and high light intensity dynamically scans the plants and the like by the guide rail part 2 in a dynamic moving (such as translation, rotation, lifting and other moving modes), so that the irradiation dead angles of the animals and the plants irradiated by the light are less; at the same time, the light intensity and the total energy of the light obtained by the plant in the unit area with more leaves on the macro scale are obviously improved, cilia on the surface of the plant leaves on the micro scale are also reduced to be shielded, and the photoreceptors on the leaf surfaces and the back sides of the leaves can have higher probability of obtaining light to obtain more opportunities for development. Further, the dynamic light source does not require a complicated light emitting structure compared to the static light source, and thus the cost of the light source section 1 is lower.

According to a preferred embodiment, the light source unit 1 further includes a light feedback analysis unit 103, and the light feedback analysis unit 103 includes at least a light emitting board subunit 103a and a light sensor 103b disposed on a light receiving surface of the light emitting board subunit 103 a. In the case that the light receiving surface of the light emitting board subunit 103a is coated with fluorescent powder, the light emitting board subunit 103a is configured to be placed on the light receiving surface side of the plant root, so as to fully utilize the light generated by the light source part 1 and/or leaked by natural light passing through the plant leaves to excite the fluorescent powder on the light receiving surface side of the light emitting board subunit 103a to emit light required by the plant, and the light can be irradiated to the plant.

Particularly preferably, the system (device) further comprises a light-emitting board subunit 103a arranged above the plant root, and the light-emitting board subunit is configured to create a dark environment for the plant root, and simultaneously, the light source part 1 and/or natural light pass through the light leaked from the plant leaf to excite the fluorescent powder to emit light required by the plant, and reflect the light to the back of the plant leaf. This is because not only the side of the plant leaf that is remote from the ground has photoreceptors, but also the side of the plant that is close to the ground has photoreceptors. Therefore, the technical scheme of the invention sufficiently utilizes the light leaked from the blades to excite the fluorescent powder to emit the light required by plants, and the light leaked from between the blades and the branches of the plants is reflected into the mid-air again in a back reflection mode through the luminescent plate which is positioned above the roots of the plants and is coated with the fluorescent powder, so that the light reflected back into the mid-air again can be absorbed and utilized by a light receptor on the side facing the ground with the blades of the plants. By the arrangement mode, the light missed by the plants can be reused through the luminescent plate which is positioned above the roots of the plants and is coated with the fluorescent powder, and the utilization rate of the plants (or animals) to the dynamic light source is improved.

According to a preferred embodiment, the control unit 3 can configure the scanning time intervals of different monochromatic lights and the sequencing of the monochromatic light scans as matched to the plant growth based on the actual growth requirements of the different plants. For example, the red and blue alternating intervals may be one hour, i.e., after the red unit is turned on to provide one hour of red illumination, the red unit is turned off and the blue unit is turned on to provide one hour of blue illumination. For another example, red light and blue light may be turned on or off simultaneously at intervals required by the plant based on the lighting requirements of the plant.

The time distribution of light is the distribution of the same light quality and light intensity combination on a light period time axis, and is mainly reflected on the difference of light supply modes. Furthermore, there are related studies that, on the basis of equal power consumption, red and blue light treatments (i.e., red and blue light alternate illumination) of different frequencies are provided. Compared with the mode of simultaneously supplying red and blue light with different frequencies, the mode of alternately supplying red and blue light with different frequencies has positive influence on plant growth and quality. For example, on an equal energy consumption basis, alternating red and blue light once in sixteen hours of light period is beneficial for accumulation of lettuce overground biomass, soluble sugars and crude proteins; the red light and the blue light alternate four times are beneficial to the accumulation of vitamin C and the metabolism of nitrate in lettuce.

On the basis of equal energy consumption, the red light and the blue light alternate for one time in the same light period are beneficial to accumulation of lettuce overground biomass, soluble sugar and crude protein; the red light and the blue light are alternated four times, which is beneficial to the accumulation of vitamin C in lettuce and the metabolism of nitrate), the red light unit and the blue light unit of the light source part 1 can alternately supply light with a certain frequency based on the illumination requirement of plants.

Particularly preferably, the control unit 3 can control the monochromatic light lamp units 101 of the light source unit 1 to supply monochromatic light of different frequencies to the area where the plants are located at a certain alternating interval and alternating frequency. For example, in one light cycle (such as one day), the control part 3 may configure the monochromatic light unit to provide an alternating frequency of different monochromatic lights matched with the plant growth requirement according to different kinds of plants, and a light supply time of the single monochromatic light. Preferably, the alternating frequency is the number of times that monochromatic light of different frequencies alternates within the same light period (e.g. one day). Preferably, the light supply time of the single red light and the light supply time of the single blue light may be the same or different.

According to a preferred embodiment, the light feedback analysis unit 103 further comprises a light analysis statistics subunit 103c. The light analysis and statistics subunit 103c can record at least the number of photons captured by the light receiving surface side of the light emitting board subunit 103a and/or energy excited by the fluorescent powder by the light sensor 103b, and can analyze and obtain growth vigor information of the plant based on the number of photons and/or the energy excited by the fluorescent powder, and can send the information of the number of photons and/or the energy excited by the fluorescent powder to the control module so that the control part 3 can adjust illumination provided to the plant.

Preferably, the growth vigor information includes, but is not limited to: growth of plant leaves.

According to a preferred embodiment, the control section 3 module further comprises a database formulation unit 301. In case the database recipe unit 301 is able to obtain the energy by which the phosphor sent by the light analysis statistics subunit 103c is excited, the database recipe unit 301 is configured to form and/or update a light meal database matching the illumination requirements of the plant based on the energy by which the phosphor is excited.

The person skilled in the art will easily form and/or update a light meal database matching the lighting requirements of each plant based on the light requirements of said plant in each plant's species, growth phase (e.g. seedling phase, quality formation phase and quality accumulation phase etc.). Since the irradiation time length and illumination intensity database of the seedling stage, the quality formation stage and the quality accumulation stage are also easily formed and updated by the skilled person according to the energy of the excited fluorescent powder, the construction of the photo-dining database is not repeated here.

According to a preferred embodiment, the light receiving surface of the light emitting panel subunit 103a comprises a first region I. The concentration of the fluorescent powder in the first area I can gradually decrease or increase along the radial direction of the plant stem with the plant stem as the center, so that the light analysis and statistics subunit 103c can at least obtain the growth condition of the plant leaf based on the change analysis of the photon number captured by one side of the light receiving surface of the light emitting board subunit 103a or the energy excited by the fluorescent powder, and then can analyze and obtain factors affecting the plant growth to optimize the light meal database.

For example, since the concentration of the phosphor in the first region I is decreased radially outward along the stem of the plant centering around the stem of the plant, it may be divided into a first annular band, a second annular band, a third annular band, and so on. Preferably, the first endless belt, the second endless belt and the third endless belt may all be centered on the plant. Preferably, the width of each endless belt is uniform. Preferably, each of the endless belts may be centered on the plant.

Thus, when the incident angle of the light emitted from the monochromatic light unit 101 to the plant changes, the light analysis statistics subunit 103c integrated with or disposed on the light receiving surface of the light emitting board subunit 103a can determine or determine the specific growth status of the plant leaves (for example, the leaves at the top are rare, or the leaves near the root are rare, or some or all of the leaves at one side are less than the normal level of the plant) by using photons received from the plant leaves in the different annular bands.

For example, as shown in fig. 3, when the top leaf of the plant is rare or less than the normal level and the rest leaves grow normally, when the monochromatic light unit is incident on the plant at a certain inclination angle (for example, the incident light is forty-five degrees from the horizontal plane), the omission from the top of the plant gradually moves from the right side to the left side of fig. 3, and at this time, the concentration of the fluorescent powder in the first area I is inconsistent, that is, the concentration of the fluorescent powder in the first to third annular bands gradually decreases, so that the light analysis statistics subunit 103c integrated or disposed in the first area I of the light emitting panel subunit 103a can recognize that the omitted light is from the top or bottom of the plant.

Particularly preferably, the light analysis and statistics subunit 103c is capable of determining from which part of the plant the missing light is incident or missing into the first region I, according to the trend of the energy excited by the phosphor in each of the annular bands during the movement of the missing light in the first region I.

For example, when the light analysis statistics subunit 103c recognizes or derives that the missing light moves from the third endless belt (on the right side of the plant as illustrated in fig. 3) to the second endless belt (on the right side of the plant as illustrated in fig. 3) by recording the number of acquired photons, the light analysis statistics subunit 103c or the control section 3 judges that the missing light comes from the top of the plant. The ray analysis statistics subunit 103c may also determine that the missing ray is from the top of the plant based on the increasing energy of the missing ray as it moves from the third annular band (on the right side of the plant as depicted in fig. 3) to the second annular band (on the right side of the plant as depicted in fig. 3). For example, when the light analysis statistics subunit 103c recognizes or derives that the missing light moves from the second endless belt (on the right side of the plant as illustrated in fig. 3) to the first endless belt (on the left side of the plant as illustrated in fig. 3) by recording the number of acquired photons, the light analysis statistics subunit 103c or the control section 3 judges that the missing light comes from the bottom of the plant. The ray analysis statistics subunit 103c may also determine that the missing ray is from the top of the plant based on the energy that is excited during the movement of the missing ray from the second endless belt (on the right side of the plant as illustrated in fig. 3) to the first endless belt (on the right side of the plant as illustrated in fig. 3) increasing and decreasing.

As another example, when the number of leaves on the left of the plant (as depicted in FIG. 3) is significantly less than the number of leaves on the right of the plant, and the light analysis statistics subunit 103c recognizes or records that the energy of the missing light from the third annular band (on the left of the plant (as depicted in FIG. 3) to the first annular band is gradually increased, and that either no excitation energy at all or only a portion of the phosphor of the first annular band (on the right of the plant (as depicted in FIG. 3) is excited, then the overall leaf growth (on the left of the plant (as depicted in FIG. 3) is determined to be significantly lower than the normal level for that type of plant.

For another example, when the overall leaf of the plant (as shown in fig. 3) is below the normal level of the plant, and the light analysis statistics subunit 103c identifies or records that the energy of the missing light excited from the third annular band (as shown in fig. 3) to the third annular band (as shown in fig. 3) is in a tendency to increase and decrease, and the average energy of the missing light excited can be higher than the average energy of the phosphor in the first region I excited by the missing light when the plant (leaf) is at the normal growth level, then the overall leaf growth (as shown in fig. 3) is determined to be significantly below the normal level of the plant.

Meanwhile, the light analysis and statistics subunit 103c can send the change trend or the determination result of the energy excited by the fluorescent powder in each annular band in the process of moving the light omitted by the plant in the first area I to the control module. Particularly preferably, the control module can be based on the obtained change trend or the determination result of the energy excited by the fluorescent powder, and compare the obtained change trend or determination result with the historical growth situation of the plant, so as to analyze and obtain the situation of specifically causing the poor growth situation (leaf blade) of the plant.

For example, if the leaves on the same side of the plant are grown sparsely or below the normal level of the plant for a long period of time, the control module determines that the cause of the adverse growth of the leaves of the plant may be due to an excessive temperature of air corresponding to the side of the plant in the plant factory or in the greenhouse or other plants on the side blocking incident light.

If the control module derives that the leaf growth at the bottom of the plant is below the normal level, the control module determines that the cause of this situation may be that the bottom of the plant is not ventilated smoothly resulting in a lower concentration of carbon dioxide than the normal demand of the plant and the leaf growth at the bottom of the plant is significantly lower than the average level of the plant.

If the control module derives that the overall leaf growth of the plant is significantly below normal, the control module determines that this may be due to the water supply at the bottom of the plant being too abundant or the fertilizer being applied exceeding the normal requirements of the plant, enabling the control module to obtain this data to optimise other elements of the plant, such as carbon dioxide concentration, indoor ventilation, indoor temperature, supply of fertilizer adapted to the plant requirements, etc. In short, the control module can further influence other adverse factors of plant growth by using the energy excited by the fluorescent powder in the first area I acquired by the light analysis and statistics subunit 103c, and store the acquired data, so as to optimize each element related to plant planting in the future plant planting process, thereby improving the yield of plants while reducing the power consumption of the system.

Preferably, the first region I may be circular.

Preferably, the radius of the first area I can be flexibly set according to practical requirements, for example, the maximum length of the shadow generated by the plant due to the light irradiation when the monochromatic light unit irradiates the plant at an incident angle of forty-five degrees.

According to a preferred embodiment, the light receiving surface of the light emitting board subunit 103a further includes a second area II, wherein the fluorescent powder of the second area II is coated on the light receiving surface of the light emitting board subunit 103a in the second area II in a manner of the same concentration, so that the light emitted by the monochromatic light lamp unit 101 and/or not blocked by the plant can directly excite the fluorescent powder of the second area II to generate the light which can be used for plant growth, and the side of the light source part 1 facing the plant can be coated with the fluorescent powder, so that the fluorescent powder on the light source part 1 can be excited again by the light emitted from the light emitting board subunit 103a to the light source part 1 to generate the light which is emitted to the plant.

Preferably, the second region II is other regions than the first sub-region of the light receiving surface of the light emitting panel subunit 103 a.

Preferably, the second region II may include a gap between plants and a region where no plants are planted irradiated by the mono-color lamp unit 101. By this arrangement, the light emitted from the light source unit 1 to the gaps between plants or the plant-free areas can be recycled by the light emitting panel subunit 103a in the second region II, thereby improving the utilization ratio of the light generated from the light source unit 1 of the present system.

Preferably, a side of the light source part 1 facing the plant can be coated with a phosphor so that the phosphor on the light source part 1 can be re-excited with the light emitted from the light emitting panel subunit 103a toward the light source part 1 to generate the light toward the plant. By this arrangement, the side of the mono-color lamp unit 101 facing the plant can be coated with phosphor so that the phosphor on the mono-color lamp unit 101 can be re-excited with the light emitted from the light emitting panel subunit 103a toward the mono-color lamp unit 101 to generate the light toward the plant.
