[0027] like Figure 1 As shown, an embodiment of the present application provides an agricultural greenhouse, which includes a main structure.

[0028] The main structure is formed by mixing the light-transmitting material and the first photoluminescent material in an integral manner.

[0029] The first photoluminescent material has a Stoke's shift, and the photoluminescent quantum yield is greater than or equal to a first preset yield; the first photoluminescent material includes a first luminescent material and a second luminescent material; the absorption spectrum of the first luminescent material is in a first wavelength range, and the emission spectrum is in a second wavelength range; the absorption spectrum of the second luminescent material is in a third wavelength range, and the emission spectrum is in a fourth wavelength range; the third wavelength range is different from the first wavelength range, and the fourth wavelength range partially overlaps with the second wavelength range.

[0030] Among them, the agricultural greenhouse is an artificial facility used for agricultural production, which is used to optimize plant growth and improve plant yield and quality by controlling environmental conditions such as temperature, humidity, and light. The agricultural greenhouse provided in this embodiment is formed by mixing the light-transmitting material and the first photoluminescent material in an integral manner, so that, on the one hand, sunlight can enter the agricultural greenhouse to maintain the temperature and humidity inside the agricultural greenhouse; on the other hand, the integrally formed agricultural greenhouse has a simple structure, and based on the first photoluminescent material with a specific spectrum, it can accurately convert specific light that has an inhibitory effect on plant growth into specific light that has a promoting effect on plant growth, so that there is no need to set up additional adjustment components to adjust the incident spectrum.

[0031] The main structure is the main supporting part of the agricultural greenhouse. The main structure provides physical support for the entire agricultural greenhouse to improve the structural stability of the agricultural greenhouse. The main structure includes a roof 102 and a side 104. The roof 102 is the top part of the main structure, which is mainly used to achieve the light transmission function; the side 104 is a component of the main structure that is arranged below the roof 102 and in contact with the ground, and is mainly used to support the roof 102. The shape design and material selection of the roof 102 and the side 104 will directly affect the lighting conditions, temperature conditions and overall structural stability of the agricultural greenhouse.

[0032] Optionally, the shape of the roof 102 can be any one of an arc shape, a ridge shape, a flat shape, and a dome shape, and thus, the shape of the main structure can be any one of a main structure with an arc shape, a main structure with a ridge shape, a main structure with a flat shape, and a main structure with a dome shape.

[0033] Optionally, the shape of the side surface 104 may be any one of a vertical side surface perpendicular to the ground, an inclined side surface gradually inclined from the bottom of the roof 102 toward the ground, and an arcuate side surface matching the arcuate roof 102, or a combination of multiple shapes.

[0034] Light-transmitting materials refer to materials that allow light to pass through. Light-transmitting materials should have the characteristics of high transparency, low light absorption, low dispersion, and low refractive index change.

[0035] In an exemplary embodiment, the light-transmitting material includes at least one of inorganic light-transmitting glass, organic polymer, fiber and nano-composite material.

[0036] The first luminescent material and the second luminescent material respectively include at least one of fluorescent quantum dots, low-dimensional perovskites and rare earth complexes.

[0037] In an exemplary embodiment, the light-transmitting material includes at least one of inorganic light-transmitting glass, organic polymer, fiber, nanocomposite material, acrylic plate and polycarbonate plate.

[0038] Among them, inorganic light-transmitting glass is an inorganic non-metallic material mainly composed of silicate (for example, silicon dioxide). Inorganic light-transmitting glass has material properties of high transparency, low refractive index change and low dispersion, thereby ensuring that light can maintain its optical properties when passing through inorganic light-transmitting glass.

[0039] Organic polymers are high molecular weight compounds formed by polymerization of organic monomers. Organic polymers have the material properties of strong plasticity, high resistance to chemical corrosion and high light transmittance.

[0040] Fiber is a thin, filamentous material, which can be a natural fiber (e.g., cotton, linen, wool) or a synthetic fiber (e.g., polyester fiber, nylon fiber). Fiber has the material properties of high material strength, high tensile strength and high flexibility.

[0041] Nanocomposites are composite materials formed by dispersing nanoscale fillers (for example, nanoparticles, nanofibers) in a matrix material (for example, polymers, metals, ceramics). Nanocomposites have the material properties of high material strength and high flexibility.

[0042] Acrylic sheet is a transparent plastic sheet made of polymethyl methacrylate (PMMA). Acrylic sheet has the characteristics of high transparency, strong impact resistance and light weight.

[0043] Polycarbonate sheet is a transparent plastic sheet made of polycarbonate (PC). Polycarbonate sheet has the material properties of high transparency, strong impact resistance and high flexibility.

[0044] Fluorescent quantum dots are a type of semiconductor nanocrystal that is approximately spherical. They can lock electrons in a very small three-dimensional space. When excited by light, the electrons in the fluorescent quantum dots will jump to a higher energy level, and thus emit light of a specific wavelength when the electrons return from a higher energy level to the ground state.

[0045] Low-dimensional perovskite refers to a one-dimensional or two-dimensional structure material formed by restricting the perovskite crystal structure in one dimension or multiple dimensions. Low-dimensional perovskite has a large exciton binding energy and a self-assembled multi-quantum well structure. When absorbing light of a specific wavelength, it can emit light of a specific wavelength through the transition and recombination process of excitons.

[0046] Rare earth complexes are compounds formed by rare earth ions (generally trivalent, Ln³⁺) and ligands (organic or inorganic ligands) through coordination bonds. The rare earth ions in rare earth complexes (for example, Er³⁺, Yb³⁺, Nd³⁺, etc.) have rich 4f energy levels and unique electronic arrangements, which can absorb light of specific wavelengths and emit light of different wavelengths.

[0047] The first photoluminescent material is a material that can absorb light energy and re-emit light energy in the form of light. After absorbing photons, the electrons of the first photoluminescent material transition from the ground state to the excited state, and then re-release the light energy in the form of light when returning from the excited state to the ground state, thereby generating a luminescent phenomenon. Specifically, since the first photoluminescent material includes the first luminescent material and the second luminescent material, the first photoluminescent material can absorb light in the absorption spectra of the first luminescent material and the second luminescent material, and emit light in the emission spectra of the first luminescent material and the second luminescent material.

[0048] Specifically, according to the application scenarios of agricultural greenhouses and the requirements for material mixing, light-transmitting materials with different colors, light transmittance, sensibility, load-bearing capacity, flexibility, curvature and other characteristics can be selected to facilitate the production of main structures suitable for different application scenarios and different rigidities. For example, agricultural greenhouses made of inorganic light-transmitting glass have higher durability and higher transparency; agricultural greenhouses made of acrylic and polycarbonate boards are relatively light in weight and have higher plasticity; agricultural greenhouses made of optical fibers have higher light conductivity.

[0049] Stokes shift refers to the phenomenon that after the first photoluminescent material or the second photoluminescent material absorbs light energy, the wavelength of the light emitted is longer than the wavelength of the absorbed light. Stokes shift usually causes the frequency of the emitted light to be lower than the frequency of the absorbed light, thereby generating an energy difference. The magnitude of the Stokes shift can be determined by calculating the difference in peak wavelength between the absorption spectrum and the emission spectrum of the first photoluminescent material or the second photoluminescent material.

[0050] Photoluminescence quantum yield refers to the ratio between the number of emitted photons and the number of absorbed photons. Materials with higher photoluminescence quantum yield can improve the efficiency of converting absorbed light energy into emitted light energy.

[0051] Optionally, the first preset yield may be 0.5, 0.7, 0.8 or a yield of other numerical values.

[0052] Specifically, the first photoluminescent material can convert the absorbed light in the first wavelength range and the light in the third wavelength range into the light in the second wavelength range and the light in the fourth wavelength range, so as to emit the light in the second wavelength range and the light in the fourth wavelength range to the plant. Therefore, in order to improve the photosynthesis efficiency of the plant, it is easy to understand that the light in the first wavelength range and the light in the third wavelength range are the light that inhibits the growth of the plant, while the light in the second wavelength range and the light in the fourth wavelength range are the light that promotes the growth of the plant.

[0053] In an exemplary embodiment, the first wavelength band ranges from 100 to 400 nm.

[0054] In an exemplary embodiment, the second wavelength band ranges from 380 to 760 nm.

[0055] In an exemplary embodiment, the third wavelength band ranges from 492 to 595 nm.

[0056] In an exemplary embodiment, the fourth wavelength band ranges from 450 to 492 nm and from 620 to 760 nm.

[0057] In an exemplary embodiment, the absorption spectrum of the first luminescent material is 100-400 nm, and the emission spectrum is 380-760 nm; the absorption spectrum of the second luminescent material is 492-595 nm, and the emission spectrum is 450-492 nm and 620-760 nm.

[0058] Specifically, 100~400nm is the ultraviolet light band, 380~760nm is the visible light band, 577~595nm is the yellow light band, 492~577nm is the green light band, 450~492nm is the blue light band, and 620~760nm is the red light band.

[0059] Specifically, the absorption spectrum of the first luminescent material is 100-400 nm and the emission spectrum is 380-760 nm, and the absorption spectrum of the second luminescent material is 492-595 nm and the emission spectrum is 450-492 nm and 620-760 nm, which are achieved based on Stokes shift.

[0060] Specifically, chlorophyll is the main pigment for photosynthesis in plants, and chlorophyll mainly absorbs red light and blue light, which are the two basic energy sources for photosynthesis; while ultraviolet radiation will reduce the leaf area of ​​plants, inhibit the elongation of the hypocotyls of plants, reduce the photosynthesis efficiency of plants, and make plants vulnerable to pathogen attacks. Based on this, the first band range is 100~400nm so that the main structure of the agricultural greenhouse can absorb ultraviolet light, and the second band range is 380~760nm so that the main structure can convert the absorbed ultraviolet light into visible light including blue light and red light, and further, the blue light and red light can be absorbed by the plants in the agricultural greenhouse for photosynthesis, that is, the first luminescent material having a specific first band range as an absorption spectrum and a specific second band range as an emission spectrum, its spectrum conversion function enables the light transmitted through the main structure to the plant to be efficiently absorbed by the chlorophyll of the plant and converted into chemical energy for better growth and development of the plant.

[0061] Specifically, plants are less sensitive to green light. Plants generally do not absorb green light because they lack receptors for green light. Moreover, plants that can only receive green light are very fragile and rarely mature. That is to say, a high proportion of green light will inhibit plant growth. In addition, since chlorophyll and carotenoids in plants have low absorption efficiency for yellow light, plants absorb less yellow light. A high proportion of yellow light will inhibit plant growth, resulting in short plants and reduced dry weight and fresh weight of plants. It can be seen that the light that is harmful to plant growth is green light and yellow light. Therefore, when optimizing lighting conditions, the growth quality and photosynthesis efficiency of plants should be improved by reducing the ratio of green light to yellow light. Based on this, the third waveband range is 492~595nm, which enables the main structure of the agricultural greenhouse to absorb green light and yellow light. The fourth waveband range is 450~492nm and 620~760nm, which enables the main structure to convert the absorbed yellow light and green light that have an inhibitory effect on plant growth into blue light and red light that have a promoting effect on plant growth, so that the blue light and red light can be absorbed by the plants in the agricultural greenhouse for photosynthesis. That is to say, the second luminescent material having a specific third waveband range as an absorption spectrum and a specific fourth waveband range as an emission spectrum, has a spectrum conversion function that enables the light transmitted through the main structure to the plants to be efficiently absorbed by the chlorophyll of the plants and converted into chemical energy for better growth and development of the plants.

[0062] It can be seen that since the first photoluminescent material has a specific emission spectrum and a specific absorption spectrum, the spectrum conversion function of the first photoluminescent material can convert ultraviolet light, yellow light and green light that have an inhibitory effect on plant growth into blue light and red light that have a promoting effect on plant growth. Obviously, the spectrum distribution of the first photoluminescent material can significantly improve the photosynthesis efficiency of plants to promote better growth of plants.

[0063] The above-mentioned agricultural greenhouse includes a main structure; the main structure is formed by mixing a light-transmitting material and a first photoluminescent material in an integral manner; wherein the first photoluminescent material has a Stokes shift, and the photoluminescent quantum yield is greater than or equal to a preset yield; the first photoluminescent material includes a first luminescent material and a second luminescent material; the absorption spectrum of the first luminescent material is in a first band range, and the emission spectrum is in a second band range; the absorption spectrum of the second luminescent material is in a third band range, and the emission spectrum is in a fourth band range; the third band range is different from the first band range, and the fourth band range partially overlaps with the second band range. The agricultural greenhouse using this embodiment can convert light that has an inhibitory effect on plant growth into light that has a promoting effect on plant growth by using the first photoluminescent material with a Stokes shift. Based on the optimized spectrum conversion effect of the agricultural greenhouse of this embodiment, the photosynthesis efficiency of plants can be significantly improved and plant growth can be promoted.

[0064] In an exemplary embodiment, the main structure includes a roof 102 and sides 104 , and the agricultural greenhouse further includes a battery assembly 106 .

[0065] The battery assembly 106 is disposed on the side surface 104 of the main structure, and is used to collect visible light incident on the roof 102 of the main structure to generate electricity for electrical equipment.

[0066] In an exemplary embodiment, the battery assembly 106 includes any one or more of a crystalline silicon battery, a cadmium telluride battery, a perovskite battery, and a copper indium gallium selenide battery.

[0067] Among them, crystalline silicon cells are a type of solar cell made of crystalline silicon material.

[0068] Cadmium telluride battery is a thin-film solar cell that uses P-type cadmium telluride semiconductor as the light-absorbing layer material.

[0069] Perovskite cell is a solar cell that uses perovskite-type organic metal halide semiconductors as light-absorbing materials.

[0070] Copper indium gallium selenide cell is a thin-film solar cell composed of copper (Cu), indium (In), gallium (Ga) and selenium (Se).

[0071] Optionally, the battery assembly 106 is disposed on a portion of the side surface 104 of the main structure; further, the battery assembly 106 may be disposed on a portion of the side surface 104 close to the roof 102 and away from the sunlight incident surface.

[0072] Optionally, the power-consuming device may be an LED lamp in an agricultural greenhouse, and thus, the LED lamp that receives the power supply signal provided by the battery assembly 106 may emit light to the plants in the agricultural greenhouse to further supplement the light for the plants, so as to further improve the photosynthesis efficiency of the plants; the power-consuming device may also be related agricultural equipment, and thus, the battery assembly 106 may serve as a power supply for these agricultural equipment. Exemplarily, the agricultural equipment may be a temperature control device for controlling the temperature conditions in the agricultural greenhouse, and the agricultural equipment may also be an intelligent irrigation device for irrigating the plants in the agricultural greenhouse.

[0073] Optionally, the battery assembly 106 may not generate electricity for the electrical equipment, but may serve as a photovoltaic battery assembly 106 to absorb light energy and store electrical energy.

[0074] Specifically, according to the actual needs of the agricultural greenhouse, battery assemblies 106 with different rigidity, transparency, and disassembly feasibility can be selected so that the battery assembly 106 can be suitable for the main structure in different application scenarios. It is easy to understand that the agricultural greenhouse provided with the battery assembly 106 is a photovoltaic agricultural greenhouse.

[0075] Specifically, since the battery assembly 106 will partially block the side 104 of the main structure, in an exemplary embodiment, the blocking area of ​​the side 104 of the main structure by the battery assembly 106 can be determined based on the photovoltaic power generation efficiency and the photosynthesis efficiency; there is a positive correlation between the photovoltaic power generation efficiency and the blocking area, and correspondingly, there is a negative correlation between the photosynthesis efficiency and the blocking area.

[0076] In this embodiment, a battery assembly is provided on the side of the main structure of the agricultural greenhouse, so that, on the one hand, the visible light incident on the roof of the main structure is beneficial to improving the photosynthesis efficiency of plants in the agricultural greenhouse to promote plant growth; on the other hand, the visible light incident on the roof of the main structure can be collected and utilized by the battery assembly to provide clean energy, thereby improving the energy utilization rate of visible light in the agricultural greenhouse.

[0077] In an exemplary embodiment, the mass fraction of the first photoluminescent material in the main structure is 0.1-0.5%.

[0078] In this embodiment, the mass fraction of the first photoluminescent material in the main structure is 0.1~0.5%, and therefore, the mass fraction of the light-transmitting material in the main structure is 99.5~99.9%. Thus, on the one hand, the light-transmitting material with a higher mass fraction can ensure that the main structure of the agricultural greenhouse has higher structural stability and reliability. On the other hand, since a certain mass fraction of the first photoluminescent material is mixed in the main structure, the main structure of the agricultural greenhouse has a spectral conversion function with a specific spectral distribution, which is beneficial to the growth of plants in the agricultural greenhouse.

[0079] like Figure 2 As shown, in an exemplary embodiment, the agricultural greenhouse further includes a light transfer film 202 .

[0080] The light transfer film 202 is composed of a second photoluminescent material; the light transfer film 202 is stacked on the sunlight incident surface of the roof 204 of the main structure by means of an adhesive.

[0081] Among them, the second photoluminescent material has a Stoke's shift, and the photoluminescent quantum yield is greater than or equal to the second preset yield; the absorption spectrum of the third luminescent material is in the fifth band range, and the emission spectrum is in the sixth band range; the absorption spectrum of the fourth luminescent material is in the seventh band range, and the emission spectrum is in the eighth band range; the seventh band range is different from the fifth band range, and the eighth band range partially overlaps with the sixth band range.

[0082] The second photoluminescent material can convert the absorbed light in the fifth wavelength range and the light in the seventh wavelength range into the light in the sixth wavelength range and the light in the eighth wavelength range, so as to emit the light in the sixth wavelength range and the light in the eighth wavelength range to the plant. Therefore, in order to improve the photosynthesis efficiency of the plant, it is easy to understand that the light in the fifth wavelength range and the light in the seventh wavelength range are the light that inhibits the growth of the plant, while the light in the sixth wavelength range and the light in the eighth wavelength range are the light that promotes the growth of the plant.

[0083] Optionally, the first photoluminescent material and the second photoluminescent material may be the same or different. Further optionally, the first wavelength range may be the same as the fifth wavelength range, the second wavelength range may be the same as the sixth wavelength range, the third wavelength range may be the same as the seventh wavelength range, and the fourth wavelength range may be the same as the eighth wavelength range.

[0084] In an exemplary embodiment, the fifth wavelength band ranges from 100 to 400 nm.

[0085] In an exemplary embodiment, the sixth wavelength band ranges from 380 to 760 nm.

[0086] In an exemplary embodiment, the seventh wavelength band ranges from 492 to 595 nm.

[0087] In an exemplary embodiment, the eighth wavelength band ranges from 450 to 492 nm and from 620 to 760 nm.

[0088] In an exemplary embodiment, the second photoluminescent material includes a third luminescent material and a fourth luminescent material; the absorption spectrum of the third luminescent material is 100-400 nm, and the emission spectrum is 380-760 nm; the absorption spectrum of the fourth luminescent material is 492-595 nm, and the emission spectrum is 450-492 nm and 620-760 nm.

[0089] Since the second photoluminescent material constituting the light transfer film 202 has a specific emission spectrum and a specific absorption spectrum, the light transfer film 202 can convert ultraviolet light, yellow light and green light that have an inhibitory effect on plant growth into blue light and red light that have a promoting effect on plant growth through the spectral conversion function of the second photoluminescent material. Obviously, the agricultural greenhouse provided with the light transfer film 202, based on the spectral distribution of the second photoluminescent material in the light transfer film 202, can further significantly improve the photosynthesis efficiency of the plant to promote better growth of the plant.

[0090] Specifically, since the light transfer film 202 is directly stacked on the sunlight incident surface of the roof 204 of the main structure through an adhesive, on the one hand, the shape of the light transfer film 202 is the same as the shape of the roof 204, and on the other hand, the light transfer film 202 is tightly fitted to the roof 204 of the main structure. For example, if the shape of the roof 204 is flat, the shape of the light transfer film 202 is also flat.

[0091] Optionally, the first preset yield may be 0.5, 0.7, 0.8 or a yield of other numerical values.

[0092] Specifically, Figure 2 As shown, the light transfer film 202 is stacked on the sunlight incident surface of the roof 204 of the main structure by adhesive, and the battery assembly 206 is arranged on the side of the roof 204 away from the sunlight incident surface, that is, the roof 204 is located between the light transfer film 202 and the battery assembly 206.

[0093] In this embodiment, the agricultural greenhouse also includes a light conversion film. Thus, based on the first photoluminescent material constituting the main structure and the second photoluminescent material constituting the light conversion film, the agricultural greenhouse can convert ultraviolet light, yellow light and green light that inhibit plant growth into blue light and red light that can promote plant growth, thereby further significantly improving the photosynthesis efficiency of plants in the agricultural greenhouse to promote better plant growth.

[0094] In an exemplary embodiment, the third light-emitting material and the fourth light-emitting material respectively include at least one of fluorescent quantum dots, low-dimensional perovskites and rare earth complexes.

[0108] In an exemplary embodiment, Figure 3 As shown, a method for making an agricultural greenhouse is provided, and the method is applied to an agricultural greenhouse making device as an example for explanation, including the following steps 302 to 304:

[0109] Step 302: Mix the first photoluminescent material with the light-transmitting material to obtain a mixed material.

[0110] The mixture between the first photoluminescent material and the light-transmitting material should be sufficiently uniform so as to ensure the uniformity of the mixed material, thereby ensuring the consistency of the spectrum conversion function at various locations of the agricultural greenhouse.

[0111] Optionally, the first photoluminescent material and the light-transmitting material may be mixed based on stirring, shaking stirring or other stirring processes.

[0112] Step 304, manufacturing an agricultural greenhouse based on integrated molding of mixed materials.

[0114] Optionally, the mixed material can be integrally formed into an agricultural greenhouse based on a blowing method, a pressing method, a condensation method or other manufacturing processes.

[0115] Optionally, the mass fraction of the first photoluminescent material in the mixed material is 0.1-0.5%.

[0116] In an exemplary embodiment, the mixing of the first photoluminescent material and the light-transmitting material to obtain the mixed material includes: mixing the first photoluminescent material in a liquid state with the light-transmitting material in a liquid state, and stirring the first photoluminescent material to uniformly distribute the first photoluminescent material in the light-transmitting material to obtain the mixed material.

[0117] For example, when the light-transmitting material is inorganic light-transmitting glass, the first photoluminescent material can be added to the molten inorganic light-transmitting glass liquid, and the first photoluminescent material is evenly distributed in the inorganic light-transmitting glass liquid by stirring to obtain a mixed material. Next, the mixed material is shaped into an integral part by blowing or pressing to obtain an integrally formed agricultural greenhouse.

Thus, on the one hand, the agricultural greenhouse, with the cooperation of the main structure and the light conversion film, can convert ultraviolet light, yellow light and green light in the visible light incident on the roof that will inhibit plant growth into blue light and red light that can promote plant growth, significantly improving the photosynthesis efficiency of plants in the agricultural greenhouse to promote better plant growth. On the other hand, the visible light incident on the roof of the main structure can be collected and utilized by the battery assembly to provide clean energy, thereby improving the energy utilization rate of visible light in the agricultural greenhouse.
