Description

Technical Field

[0001] The invention belongs to the technical field of plant cultivation equipment, in particular to an LED lighting cultivation box suitable for studying factors affecting plant growth. Background Art

[0002] In the field of biology, the study of factors affecting plant growth has important scientific significance and application value. By simulating the lighting conditions in the natural environment, researchers can accurately control the lighting environment in which plants grow, thereby deeply exploring the effects of factors such as light intensity, photoperiod, and light quality on plant growth and development, and thus provide more accurate experimental data for plant science research.

[0003] When studying plant growth factors, in order to facilitate the adjustment of parameters such as light intensity, light duration, temperature and humidity in the plant environment, plants are usually cultured in incubators, thereby isolating the plants from the external environment and making it easier to adjust the parameters of their growth environment. Among the factors affecting plant growth, light is a crucial factor. In incubators, LED light sources are often used to simulate natural light and create a lighting environment for plants. With the advancement of technology, by connecting LED light sources to system programs, LED luminous power, luminous flux, spectral distribution and other parameters can be artificially adjusted through external devices, thereby creating more controllable variables for plant lighting experiments and enhancing the flexibility and accuracy of plant lighting experiments. In addition, with advanced temperature and humidity control systems, ventilation systems, etc., through these comprehensive control functions, researchers can more accurately simulate and study the response of plants to different environmental factors.

[0004] For example, a smart LED light-controlled biological incubator and a method of use are disclosed in the related art, and the application number is CN2023108431705, which includes a culture box body and a base arranged at the bottom of one side of the culture box body; by synchronously driving a plurality of reflective rollers in the culture box body to rotate continuously, it is convenient to fully expand the illumination surface by utilizing the principle of light reflection, and under the control of the light sensor and the processor in the control panel, the rotation speed of the reflective roller and the number of lights turned on are intelligently controlled to provide a suitable light intensity, which provides a good supplement and guarantee for the illumination of microorganisms. At the same time, the fan is linked to ventilate the culture box body, and the heat emitted by the servo motor itself can be used to provide temperature support for the culture box body. However, in the plant illumination experiment, the plant has multiple parts, and there are new and old parts in multiple parts. Therefore, when controlling the illumination conditions, it is necessary not only to adjust the conditions such as the light intensity and spectral distribution, but also to adjust the illumination position and illumination range.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] like Figures 1 to 8As shown, the LED illumination culture box suitable for studying factors affecting plant growth described in the present invention comprises a box body 1, an environment control module and an LED light source 11. A plurality of culture chambers 12 are provided in the box body 1. The environment control module and the LED light source 11 are installed in each of the culture chambers 12. The environment control module is used to control the temperature, humidity and carbon dioxide content in the culture chamber 12, and the LED light source 11 is used to provide illumination.

[0040] It also includes a lighting control module, which is used to adjust the lighting position of the LED light source 11 on the plant;

[0041] The illumination control module includes a parameter adjustment component and an illumination adjustment component;

[0042] The parameter adjustment component is used to adjust the intensity and spectral range of the LED light source 11, and the irradiation adjustment component is used to adjust the irradiation position of the LED light source 11 on the plant;

[0043] The irradiation adjustment assembly includes a mounting plate 2, an extension line 21 and a support tube 22;

[0044] The mounting plate 2 is mounted on the top of the culture chamber 12, and evenly distributed extension wires 21 are fixedly mounted on the mounting plate 2. The extension wires 21 correspond to the LED light sources 11 one by one, and the LED light sources 11 are externally connected to a power supply through the extension wires 21;

[0045] A support tube 22 is fixedly mounted on the mounting plate 2 . The support tube 22 is made of soft plastic metal material. The LED light source 11 is fixedly mounted on the end of the support tube 22 .

[0046] In the study of factors affecting plant growth, one of the more common experiments is to verify plant changes by adjusting lighting conditions during the experiment. When adjusting lighting conditions, in order to improve the comprehensiveness of experimental research data, during the experiment, not only the intensity and spectral range of the LED light source 11 can be adjusted, but also the irradiation position of the plant can be adjusted by adjusting the LED light source 11 in the present invention to verify the effects of light on different parts of the plant and different positions of the same part, thereby making the data collected by the lighting experiment more comprehensive.

[0047] Specifically, in the plant illumination experiment, the parameter adjustment component can adjust the voltage, current and other parameters of multiple lamp beads in the LED light source 11 according to the adjustment of the control program, and then adjust the luminous intensity, spectral range, etc. of the LED light source 11, so that the LED light source 11 can flexibly adjust the experimental parameters in different experimental groups according to the experimental design plan. At the same time, the setting of the illumination adjustment component is more convenient for adjusting the illumination position of the LED light source 11 on the plant. In the experiment, it is used to verify the changes caused by the same illumination conditions in different parts of the plant and different areas of the same part, such as the illumination effect verification of different parts such as stems and leaves of seedlings, the illumination effect verification of new and old leaves, etc., so as to design the experimental plan more flexibly. When adjusting the illumination position of the LED light source 11, the staff manually pulls the LED light source 11 to adjust the relative angle and distance between the light source emitted by the LED light source 11 and the plant, and then adjusts the illumination position of the LED light source 11 on the plant. Since the LED light source 11 is fixedly installed on At the end of the support tube 22, an extension line 21 for connecting the LED light source 11 to the power supply passes through the inner cavity of the support tube 22. The support tube 22 is made of soft plastic metal material, preferably copper alloy, aluminum alloy and the like. When an external force acts, the support tube 22 undergoes plastic deformation, so that the LED light source 11 installed at its end can move in the culture chamber 12. At the same time, because the support tube 22 has hardness and the gravity of the LED light source 11 is less than the plastic deformation force of the support tube 22, after the position of the LED light source 11 is manually adjusted, the support tube 22 can support the LED light source 11, so that the LED light source 11 is stable at the corresponding position. Then, according to the designed experimental plan, the light variables received by various parts of the plant can be flexibly adjusted, so that the design flexibility of the variables in the experimental group is higher. At the same time, when conducting experiments on smaller plants such as seedlings, the distance between the LED light source 11 and the plant can be adjusted, thereby reducing the illumination area and reducing the luminous power of the LED light source 11 while ensuring the light intensity.

[0048] The present invention increases the range of variation of plant lighting variables by setting an illumination adjustment component and changing the position of the LED light source 11. Compared with the incubator with a relatively fixed light source position in the related art, not only can the incubator have more functions, but also the flexibility and variability in the design of experimental schemes can be correspondingly enhanced, and the comprehensiveness of the lighting experiment can be improved. In addition, the power of the LED light source 11 can be flexibly adjusted by adjusting the position and parameters of the LED light source 11 when the lighting range requirements are different, thereby enhancing the energy-saving effect of the incubator.

[0049] As a preferred embodiment of the present invention, the illumination adjustment component further includes a focusing tube, which is detachably mounted on the LED light source 11 and is used to cover the light emitted by the LED light source 11;

[0050] The focusing tube includes a tube body 23 and a cover shell 24;

[0051] The cylinder 23 is detachably fixedly connected to the LED light source 11, and a symmetrically designed cover 24 is hingedly installed at one end of the cylinder 23 away from the LED light source 11 through a torsion spring. The cover 24 and the cylinder 23 surround to form a cylindrical cavity structure, and the cover 24 and the cylinder 23 are both made of opaque material.

[0052] In order to further enhance the contrast effect of illumination variables, a focusing tube is further provided in the present invention, which covers the illumination position to prevent light leakage and affect the change of the non-illumination position of the plant, thereby enhancing the control effect of the experimental parameters. Specifically, when adjusting the relative position between the LED light source 11 and the plant according to the experimental plan and then adjusting the illumination range of the plant, the staff installs the focusing tube on the LED light source 11, then pulls the combination of the LED light source 11 and the focusing tube, and then manually opens the cover 24, so that the plant to be illuminated can be illuminated through the gap of the cover 24. The parts enter the space covered by the cover 24 and the cylinder 23. For example, when conducting a lighting experiment on new and old leaves, the staff can use the cover 24 and the cylinder 23 to cover the outside of the new or old leaves, and then make the light emitted by the LED light source 11 act only on the new leaves or old leaves, thereby testing the effect of the new and old leaves on plant growth under the lighting environment. Or when conducting a lighting experiment on plant seedlings, part of the seedlings can be covered in the cover 24 and the cylinder 23, and the other part is placed in the dark environment of the culture chamber 12, thereby conducting experiments in two environments in the same culture chamber 12.

[0053] As a preferred embodiment of the present invention, a plurality of contact grooves 25 are formed on the sides of the two covers 24 close to each other, and uniformly distributed elastic sheets 26 are installed in the contact grooves 25 . In the initial state, the elastic sheets 26 block the contact grooves 25 .

[0054] The cover shell 24 is provided with a telescopic slot 27 , and the elastic sheets 26 extend into the telescopic slot 27 . Evenly distributed spring rods 28 are fixedly installed in the telescopic slot 27 . The spring rods 28 correspond to the elastic sheets 26 one by one, and the elastic sheets 26 are fixedly connected to the spring rods 28 .

[0055] The design of the contact groove 25 and the elastic sheet 26 is to enhance the light isolation effect and reduce the chance of plant damage during partial plant illumination experiments. Specifically, the staff manually swings the cover 24 to open the cover 24, then extends a part of the plant into the inner cavity of the cover 24 and the cylinder 23, and closes the cover 24. During this process, the elastic sheet 26 in the contact groove 25 contacts the plant and blocks the gap in the cover 24. With the arrangement of the spring rod 28 and the telescopic groove 27, the elastic sheet 26 in contact with the plant can squeeze the spring rod 28 and shrink into the telescopic groove 27. On the one hand, the elastic sheet 26 made of elastic material reduces the degree of damage to the plant compared to hard materials. On the other hand, the presence of multiple elastic sheets 26 can be used to block the gap between the cover 24 and the plant as much as possible, thereby reducing the amount of light leakage.

[0056] As a preferred embodiment of the present invention, a storage cavity 13 is opened on one side of the box body 1, and a plurality of light-collecting tubes are placed in the storage cavity 13, and the plurality of light-collecting tubes have a plurality of sizes.

[0057] Multiple different models of focusing tubes are suitable for experiments on plants of different sizes, making it easier for staff to select according to the actual experimental design.

[0058] As a preferred embodiment of the present invention, the focusing tube also includes a combination ring 29 , which has a matching groove 2A in the circumferential direction, and the matching groove 2A matches the elastic sheet 26 . The combination ring 29 is designed in multiple numbers and is used to form a through hole on the cover shell 24 .

[0059] The provision of the combination ring 29 can further reduce the damage to the plants when the cover 24 is closed. Specifically, in the relatively tender parts of the plants, the staff will put the combination ring 29 consisting of two half rings on the plant tissue before closing the cover 24, and then close the cover 24. During the closing process, the combination ring 29 is aligned with the elastic sheets 26 on the cover 24, and then the combination ring 29 is used to open a through hole between the evenly arranged elastic sheets 26. It should be noted that in actual application, the combination ring 29 is composed of two half rings, and the half rings can be semicircular or arc-shaped, so as to reduce the chance of plant damage in experiments where some plants are more easily damaged. In order to enhance the shading performance of the combination ring 29, after the cover 24 is combined with the combination ring 29, the gap between the combination ring 29 and the plant tissue is sealed by using tools such as opaque tape to enhance the light isolation effect.

[0060] As a preferred embodiment of the present invention, a modification groove 3 is opened inside the support tube 22, and the modification groove 3 is filled with electrorheological fluid. An insulating sleeve 31 is provided on the outside of the support tube 22. The support tube 22 is electrically connected to the power supply through a wire. A push switch 32 is fixedly installed on the mounting plate 2. The push switch 32 is located in the middle of the wire. The push switch 32 is used to control the circuit conduction state between the power supply and the support tube 22.

[0061] By opening a modified groove 3 inside the support tube 22 and filling the modified groove 3 with an electrorheological liquid, the push switch 32 is disconnected in the initial state, so that the circuit between the support tube 22 and the power supply is disconnected. At this time, the electrorheological liquid is in liquid state, and the support tube 22 is supported only by the performance of its own material. When the position of the support tube 22 and the LED light source 11 at its end is determined, the staff manually turns on the push switch 32, so that the circuit between the power supply and the support tube 22 is connected. Under the action of the electric field, the electrorheological liquid solidifies, and then supports in accordance with the performance of the material of the support tube 22 itself. At this time, the deformation difficulty of the support tube 22 is greatly increased, so that the position fixing effect of the LED light source 11 is better. In actual application, the insulating sleeve 31 sleeved on the outside of the support tube 22 cooperates with the support tube 22 to form a structure similar to a wire, and the insulating sleeve 31 can be used to effectively avoid current leakage. It should be noted that the modified groove 3 is not connected to the inner cavity of the support tube 22, and the extension wire 21 itself is a wire wrapped with an insulating skin, so the circuit between the LED light source 11 and the support tube 22 is not connected.

[0062] As a preferred embodiment of the present invention, the mounting plate 2 is provided with evenly distributed receiving grooves 4 , and the support tubes 22 are coiled and received in the receiving grooves 4 in an initial state.

[0063] A guide column 41 is installed in the receiving groove 4, a spiral groove is opened on the guide column 41, a guide plate 42 is rotatably installed on the guide column 41, the guide plate 42 extends into the spiral groove, a wire hole 43 is opened on the guide plate 42, and the middle part of the support tube 22 is located in the wire hole 43.

[0064] The guide plate 42 is detachably provided with a rotating rod 5 , and the rotating rod 5 is used for assisting in rotating the guide plate 42 .

[0065] The storage groove 4 is set to store the support tube 22. Specifically, when storing, the staff disconnects the press switch 32, so that the electrorheological fluid loses the electric field effect and is converted from solid to liquid. Then, the rotating rod 5 is manually connected to the guide plate 42, and the guide plate 42 is pushed to rotate around the guide column 41 through the rotating rod 5. Since the guide plate 42 extends into the spiral groove, during the rotation of the guide plate 42, the guide plate 42 continues to move downward along the spiral groove. Since one end of the support tube 22 is fixed on the mounting plate 2, the middle part of the support tube 22 is located in the wire hole 43 on the guide plate 42. Therefore, as the guide plate 42 rotates, the support tube 22 is gradually coiled around the guide column 41, thereby realizing the storage of the support tube 22, so that the LED light source 11 at the end of the support tube 22 moves to the top of the culture chamber 12, and when releasing the support tube 22, the staff only needs to rotate the guide plate 42 in the opposite direction through the rotating rod 5, thereby gradually loosening the coiled support tube 22.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
