Description

Technical Field

[0001] This invention belongs to the technical field of plant cultivation equipment, specifically an LED light incubator suitable for studying factors affecting plant growth. Background Technology

[0002] In the field of biology, the study of factors influencing plant growth has significant scientific importance and practical value. By simulating light conditions in the natural environment, researchers can precisely control the light environment for plant growth, thereby exploring the effects of factors such as light intensity, photoperiod, and light quality on plant growth and development, and ultimately providing more accurate experimental data for plant science research.

[0003] In studying plant growth factors, plants are typically cultivated in incubators to facilitate the adjustment of parameters such as light intensity, duration of light exposure, temperature, and humidity. This isolates the plants from the external environment, making it easier to regulate their growth parameters. Light is a crucial factor influencing plant growth. In incubators, LED light sources are often used to simulate natural light, creating a suitable lighting environment for the plants. With technological advancements, connecting LED light sources to system programs allows for the manual adjustment of parameters such as LED power, luminous flux, and spectral distribution via external devices. This adds more controllable variables to plant lighting experiments, enhancing their flexibility and accuracy. Furthermore, with advanced temperature and humidity control systems and ventilation systems, researchers can more accurately simulate and study plant responses to different environmental factors.

[0004] For example, a related technology discloses an intelligent LED light-controlled biological incubator and its usage method (application number CN2023108431705), which includes an incubator body and a base set at the bottom of one side of the incubator body. Several reflective rollers inside the incubator rotate continuously via synchronous transmission, facilitating the full expansion of the illuminated area using the principle of light reflection. Under the control of a light sensor and a processor within the control panel, the rotation speed of the reflective rollers and the number of lights turned on are intelligently controlled to provide appropriate light intensity, thus providing a good supplement and guarantee for the light of microorganisms. Simultaneously, a fan is activated to ventilate the incubator body, and the heat dissipated by the servo motor itself provides temperature support within the incubator body. However, in plant light experiments, plants have multiple parts, and these parts vary in age. Therefore, when controlling light conditions, it is necessary not only to adjust light intensity and spectral distribution but also to adjust the illuminated parts and the light range. The light system in the incubator of the related technology does not have the capability for fine-tuning the irradiation range, thus limiting the research on factors affecting plant growth.

[0005] In view of this, the present invention proposes an LED light incubator suitable for studying factors affecting plant growth, in order to solve the above-mentioned technical problems. Summary of the Invention

[0021] Preferably, the support tube has a modified groove inside, which is filled with electrorheological fluid. The support tube is covered with an insulating sleeve. The support tube is electrically connected to a power source through a wire. A push switch is fixedly installed on the mounting plate.

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 8As shown, the present invention provides an LED light incubator suitable for studying factors affecting plant growth, comprising a chamber 1, an environmental control module, and an LED light source 11. The chamber 1 has multiple culture chambers 12, each of which is equipped with an environmental control module and an LED light source 11. The environmental control module is used to control the temperature, humidity, and carbon dioxide content within the culture chamber 12, and the LED light source 11 is used to provide light.

[0040] It also includes a light control module, which is used to adjust the position of the LED light source 11 irradiating 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 installed at the top of the culture chamber 12. The mounting plate 2 is fixedly installed with evenly distributed extension lines 21. The extension lines 21 correspond one-to-one with the LED light source 11. The LED light source 11 is connected to an external power supply through the extension lines 21.

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

[0046] In studies on factors affecting plant growth, one common method is to adjust light conditions during the experiment to verify changes in the plant. To improve the comprehensiveness of experimental data, during the adjustment of light conditions, not only can the intensity and spectral range of the LED light source 11 be adjusted, but the position of the LED light source 11 on the plant can also be adjusted to verify the effects of light on different parts of the plant and different positions of the same part, thereby making the data collected from the light experiment more comprehensive.

[0047] Specifically, in plant illumination experiments, the parameter adjustment component can adjust the voltage, current, and other parameters of multiple LED beads in the LED light source 11 according to the control program, thereby adjusting the luminous intensity and spectral range of the LED light source 11. This allows the LED light source 11 to flexibly adjust experimental parameters in different experimental groups according to the experimental design. Furthermore, the illumination adjustment component facilitates the adjustment of the illumination position of the LED light source 11 on the plant. In experiments, it is used to verify the changes produced by the same light conditions on different parts of the plant and different areas of the same part, such as verifying the light effect on different parts of the seedling stem and leaves, and the light effect on new and old leaves, etc., to facilitate more flexible experimental design. 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 emitted by the LED light source 11 and the plant, thus adjusting the illumination position of the LED light source 11 on the plant. Since the LED light source 11 is fixedly installed... At the end of the support tube 22, the 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, etc. When an external force is applied, the support tube 22 undergoes plastic deformation, allowing the LED light source 11 installed at its end to move within the culture chamber 12. At the same time, because the support tube 22 has hardness, when the weight of the LED light source 11 is less than the plastic deformation force of the support tube 22, the support tube 22 can support the LED light source 11 after the position of the LED light source 11 is manually adjusted, so that the LED light source 11 is stable in the corresponding position. Thus, according to the designed experimental plan, the light variables received by various parts of the plant can be flexibly adjusted, making the design of variables in the experimental group more flexible. At the same time, when conducting experiments on small plants such as seedlings, the distance between the LED light source 11 and the plant can be adjusted to reduce the light area and reduce the luminous power of the LED light source 11 while ensuring the light intensity.

[0048] This invention, by setting up an illumination adjustment component and changing the position of the LED light source 11, increases the range of variation in plant light variables. Compared with incubators in related technologies where the light source position is relatively fixed, this invention not only increases the functionality of the incubator and enhances the flexibility and variability of experimental design, improving the comprehensiveness of light experiments, but also allows for flexible adjustment of the power of the LED light source 11 by adjusting its position and parameters to meet different light range requirements, thereby enhancing the energy-saving effect of the incubator.

[0049] In a preferred embodiment of the present invention, the illumination adjustment assembly 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 24;

[0051] The cylindrical body 23 is detachably and fixedly connected to the LED light source 11. A symmetrically designed cover 24 is installed at the end of the cylindrical body 23 away from the LED light source 11 via a torsion spring. The cover 24 and the cylindrical body 23 surround each other to form a cylindrical cavity structure. Both the cover 24 and the cylindrical body 23 are made of opaque material.

[0052] To further enhance the contrast effect of light variations, this invention also includes a spotlight tube. The spotlight tube covers the light-emitting area, preventing light leakage and affecting changes in the non-light-emitting areas of the plant, thereby enhancing the control of experimental parameters. Specifically, when adjusting the relative position between the LED light source 11 and the plant according to the experimental plan to adjust the plant's light range, the operator installs the spotlight tube on the LED light source 11, then pulls the connection between the LED light source 11 and the spotlight tube, and then manually pries open the cover 24. Through the gap in the cover 24, the plant prepared to receive light is exposed to the light. The parts enter the space covered by the cover 24 and the cylinder 23. For example, when conducting light experiments on new and old leaves, the staff can cover the outside of the new or old leaves with the cover 24 and the cylinder 23, so that the light emitted by the LED light source 11 only acts on the new or old leaves, and then test the effect of new and old leaves on plant growth under light conditions. Or, when conducting light experiments on plant seedlings, some seedlings are covered inside the cover 24 and the cylinder 23, while the other part is placed in the dark environment of the culture chamber 12, and then experiments on two environments are carried out in the same culture chamber 12.

[0053] In a preferred embodiment of the present invention, the two covers 24 are provided with a plurality of contact grooves 25 on one side close to each other, and 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 24 is provided with a telescopic groove 27, and the elastic sheets 26 all extend into the telescopic groove 27. The telescopic groove 27 is fixedly installed with evenly distributed spring rods 28, and the spring rods 28 correspond one-to-one with the elastic sheets 26. 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 light exposure experiments. Specifically, the operator manually swings the cover 24 to open it, then inserts 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 comes into contact with the plant and seals the gap in the cover 24. With 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 retract 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 seal the gap between the cover 24 and the plant as much as possible, thereby reducing the amount of light leakage.

[0056] In a preferred embodiment of the present invention, a storage cavity 13 is provided on one side of the box body 1, and multiple focusing tubes are placed in the storage cavity 13, and the multiple focusing tubes have multiple sizes.

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

[0058] In a preferred embodiment of the present invention, the focusing tube further includes a combination ring 29, wherein a mating groove 2A is provided in the circumferential direction of the combination ring 29, the mating groove 2A is matched with the elastic sheet 26, the combination ring 29 is designed in multiples, and the combination ring 29 is used to form through holes in the cover 24.

[0059] The combination ring 29 further reduces damage to the plant when the cover 24 is closed. Specifically, for more tender parts of the plant, before closing the cover 24, the staff places the combination ring 29, consisting of two semi-rings, onto the plant tissue. Then, the cover 24 is closed, and during the closing process, the combination ring 29 is aligned with the elastic sheet 26 on the cover 24. The combination ring 29 is then used to create through holes between the evenly arranged elastic sheets 26. It should be noted that in practical applications, the combination ring 29 consists of two semi-rings, and the semi-rings can be semi-circular or arc-shaped, etc., to reduce the chance of plant damage in experiments where some plants are more easily damaged. To enhance the light-blocking performance of the combination ring 29, after the cover 24 and the combination ring 29 are combined, the gap between the combination ring 29 and the plant tissue is sealed using tools such as opaque tape to enhance the light-blocking effect.

[0060] In a preferred embodiment of the present invention, a modified groove 3 is provided inside the support tube 22, and the modified groove 3 is filled with electrorheological liquid. An insulating sleeve 31 is provided outside 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 and is used to control the circuit conduction state between the power supply and the support tube 22.

[0061] By creating a modified groove 3 inside the support tube 22 and filling it with electrorheological fluid, the circuit between the support tube 22 and the power supply is initially disconnected when the push switch 32 is turned off. At this time, the electrorheological fluid is in a liquid state, and the support tube 22 relies solely on the properties of its own material for support. However, once the positions of the support tube 22 and the LED light source 11 at its end are determined, the operator manually turns on the push switch 32, causing the circuit between the power supply and the support tube 22 to become conductive. Under the action of the electric field, the electrorheological fluid solidifies, and then, in conjunction with the properties of the support tube 22's own material, it provides support. At this time, the difficulty of deformation of the support tube 22 increases significantly, thus resulting in a better fixation effect for the position of the LED light source 11. In practical applications, the insulating sleeve 31 covering the outside of the support tube 22 forms a structure similar to a wire, effectively preventing current leakage. It should be noted that the modified groove 3 and the inner cavity of the support tube 22 are not conductive, and the extension line 21 itself is a wire wrapped with insulation. Therefore, the circuit between the LED light source 11 and the support tube 22 is not conductive.

[0062] In a preferred embodiment of the present invention, the mounting plate 2 is provided with uniformly distributed storage grooves 4, and in the initial state, the support tube 22 is coiled and stored in the storage grooves 4.

[0063] A guide post 41 is installed in the storage slot 4. A spiral groove is opened on the guide post 41. A guide disk 42 is rotatably installed on the guide post 41. The guide disk 42 extends into the spiral groove. A wire hole 43 is opened on the guide disk 42. The middle part of the support tube 22 is located in the wire hole 43.

[0064] A rotating rod 5 is detachably mounted on the guide disk 42, and the rotating rod 5 is used to assist in rotating the guide disk 42.

[0065] The storage slot 4 is designed to store the support tube 22. Specifically, during storage, the operator disconnects the press switch 32, causing the current-to-liquid converter to lose its electric field effect and transform from a solid to a liquid. Then, the operator manually connects the rotating rod 5 to the guide plate 42 and pushes the guide plate 42 to rotate around the guide post 41 via the rotating rod 5. Since the guide plate 42 extends into the spiral groove, it continues to move downwards along the spiral groove during rotation. Because one end of the support tube 22 is fixed to the mounting plate 2, and the middle of the support tube 22 is located in the wire hole 43 on the guide plate 42, the support tube 22 gradually winds around the guide post 41 as the guide plate 42 rotates, thus storing the support tube 22. This allows the LED light source 11 at the end of the support tube 22 to move to the top of the culture chamber 12. When releasing the support tube 22, the operator only needs to rotate the guide plate 42 in the opposite direction via the rotating rod 5, thereby gradually loosening the wind-up support tube 22.

[0066] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
