Description

Technical Field

[0001] This utility model relates to the field of plant lights, specifically a supplemental light for assisting plant growth, mainly targeting the optimization and adjustment of the environment at the bottom of the plant canopy. Background Technology

[0002] In modern agricultural production, plant factories, as a highly efficient and controllable planting method, are widely used in the cultivation of high-density cash crops. However, existing plant factory environmental control technologies still have many shortcomings, especially in optimizing the microenvironment at the base of the canopy. In plant factories, for high-density cash crops, a design combining top-suspended supplemental lighting with horizontal circulating fans is commonly used. However, in this high-density planting environment, the following shortcomings exist.

[0003] 1. Insufficient microenvironment regulation at the bottom of the canopy, with top supplemental lighting and side fans failing to effectively improve ventilation dead zones at the bottom of the canopy, leads to uneven CO2 concentration gradients and affects the efficiency of gas absorption by plant stomata.

[0004] 2. The bottom of the canopy is in a high humidity and low light environment for a long time, which makes it easy for leaf diseases such as gray mold and downy mildew to grow. Current technology lacks an active intervention mechanism for the humidity of the bottom microenvironment.

[0005] 3. Low gas utilization efficiency: The stomata of dicotyledonous crops are mainly distributed on the back of the leaves. Traditional horizontal air supply cannot directly act on the dense area of ​​stomata, and the horizontal air supply mode is difficult to penetrate the leaf layer at the bottom of the canopy.

[0006] 4. Energy redundancy: Independent CO2 delivery systems require additional equipment and are separate from supplementary lighting devices, resulting in complex installation and high operation and maintenance costs.

[0007] 5. Lack of dynamic response: Most existing fans use a fixed speed and cannot adjust the wind speed in real time according to the temperature and humidity of the canopy, which can easily cause local oversaturation or gas waste.

[0008] 6. Leaf shading effect: In high-density planting environments, crop leaves overlap, resulting in uneven light exposure for the middle and lower leaves. Traditional static supplemental lighting cannot effectively solve the problem of leaf self-shading, leading to a decrease in photosynthetic efficiency.

[0009] In summary, existing technologies have significant shortcomings in terms of canopy bottom microenvironment regulation, gas utilization efficiency, dynamic response capability, and disease control. There is an urgent need for a technical solution that can integrate supplemental lighting and ventilation functions, achieve dynamic regulation, and optimize the canopy bottom microenvironment in order to improve the production efficiency and crop quality of plant factories. Summary of the Invention

[0010] To address the aforementioned technical problems, this invention provides a supplemental light for assisting plant growth, which has the advantages of improving ventilation dead zones at the bottom of the canopy, promoting uniform CO2 distribution, reducing humidity to suppress leaf diseases, and improving gas utilization efficiency.

[0011] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0012] A supplemental light for assisting plant growth includes a lamp fixture with a light-emitting component. The lamp fixture has input and output terminals at both ends. A vertical air supply module is located on the side of the lamp fixture, supplying air vertically upwards in a laminar flow. A controller is located inside the lamp fixture, and both the vertical air supply module and the light-emitting component are connected to the controller. A partition is located inside the lamp fixture, dividing the internal space into independent air outlet and heat dissipation chambers. A heat dissipation vent is located on the end cap. A breathing valve is located on the lamp fixture corresponding to the area of ​​the heat dissipation chamber, and the air outlet is located in the area of ​​the air outlet chamber.

[0013] As a further improvement, the vertical air supply module includes a fan and an air outlet. The air outlet is located on the upper surface of the lamp, and the fan is mounted on one side of the lamp. When the fan is running, it drives the air to be discharged from the air outlet.

[0014] As a further improvement, the lamp is equipped with end caps on both sides, and the contact area between the end caps and the lamp is coated with waterproof silicone or fitted with sealing gaskets.

[0015] As a further improvement, the fan is mounted on the end cover via a fan bracket, and a housing is fitted around the fan. The bottom of the housing has an air inlet corresponding to the fan, and the housing is connected to the end cover.

[0016] As a further improvement, the end cap connected to the fan is provided with a vent. The air outlet of the fan is connected to the vent, and the air generated by the fan enters the lamp through the vent and is discharged from the air outlet.

[0017] As a further improvement, the end cap connected to the housing is provided with a drainage hole in the area corresponding to the air outlet cavity, and the housing is provided with a water outlet hole.

[0018] As a further improvement, the luminaire is equipped with an environmental sensing module, which is connected to the controller.

[0019] As a further improvement, the environmental sensing module includes a temperature and humidity sensor, a light intensity sensor, and a carbon dioxide sensor.

[0020] As a further improvement, the air outlets are evenly distributed along the length of the lamp.

[0021] As a further improvement, a vertical air supply module is provided on one side of the lamp; or vertical air supply modules are provided on both sides of the lamp.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. Targeted solutions to gas diffusion problems

[0024] The vertical upward airflow design directly drives the stagnant air at the bottom of the plant canopy, forming a directional airflow from bottom to top, so that CO2 is evenly distributed in the densely stomata on the back of the leaves.

[0025] 2. Improve resource utilization efficiency

[0026] It integrates supplemental lighting and ventilation functions, and uses the same device to simultaneously optimize light energy supply and gas exchange, reducing equipment redundancy and lowering energy consumption.

[0027] 3. Dynamic environment adaptability

[0028] A temperature and humidity feedback control mechanism is introduced to adjust the wind speed in real time according to the canopy microenvironment, maintaining a suitable airflow speed range of 0.5-1m / s to avoid excessive ventilation that could lead to leaf dehydration.

[0029] 4. Crop physiological adaptability

[0030] Based on the stomatal distribution characteristics of dicotyledonous plants, CO2 absorption efficiency can be improved through the coordinated design of airflow direction and leaf spatial arrangement.

[0031] 5. Disease suppression efficacy

[0032] The directional airflow formed by vertical air supply can accelerate the replacement of moist air at the bottom, reduce the relative humidity at the bottom of the canopy, avoid high humidity in the microenvironment at the bottom of the canopy, thereby destroying the conditions for pathogen spore attachment and germination, and reducing the occurrence of diseases.

[0033] 6. Light distribution optimization performance:

[0034] The blade disturbance effect generated by vertical airflow can cause dynamic changes in the blade gap, increasing the light exposure time of the bottom blades and reducing the impact of blade shading. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0047] Example 1

[0048] like Figure 1-6 As shown, a supplemental light for assisting plant growth includes a lamp 1, a light-emitting component 2 on the lamp 1, an input terminal 7 and an output terminal 4 at both ends of the lamp 1, a vertical air supply module on the side of the lamp 1, the vertical air supply module supplies air in the vertical direction of the lamp to form a vertically upward laminar flow, a controller is provided inside the lamp, and the vertical air supply module and the light-emitting component are both connected to the controller.

[0049] The vertical air supply module includes a fan 5 and an air outlet 6. The air outlet 6 is located on the upper surface of the lamp 1, and the fan 5 is mounted on one side of the lamp 1. When the fan 5 is running, it drives air to be discharged from the air outlet 6. It is connected to an external power supply and other components through input terminals 7 and output terminals 4. The light-emitting components include light of various colors and wavelengths, such as white light and ultraviolet light, with the ultraviolet light capable of antibacterial treatment. The fan can be selected as an axial flow type.

[0050] The vertical air supply module, installed on the side of the lamp, is an airflow generator. It can be implemented using an axial fan with a guide structure, controlling the airflow direction by adjusting the blade angle and speed. Laminar flow refers to airflow rising uniformly in a parallel flow pattern. The controller is a circuit module with signal processing capabilities, which can be a microprocessor; the model and type can be flexibly selected. Input and output terminals are the power and signal transmission interfaces, which can be achieved using waterproof connectors to power multiple lamps in series.

[0051] The airflow generated by the vertical air supply module rises vertically along the surface of the lamp, forming a directional flow as it penetrates the crop canopy. Laminar flow characteristics allow the airflow to penetrate deep into the leaf gaps, directly affecting the stomatal distribution area. The controller receives environmental data and synchronously adjusts the fan speed and supplemental lighting intensity. When excessive humidity is detected at the bottom of the canopy, the controller can increase airflow to accelerate moisture evaporation; during periods of insufficient light, it increases the output of the light-emitting components and coordinates with airflow for heat dissipation. The terminal design at both ends of the lamp supports cascading of multiple devices, simplifying the wiring structure of the plant factory.

[0052] The vertical laminar flow design ensures airflow reaches the bottom of the canopy directly along the plant's growth direction, improving the uniformity of CO2 distribution in the stomatal region. An integrated controller replaces a separate environmental control system, avoiding control delays associated with multi-device collaboration. The physical integration of supplemental lighting and ventilation reduces the equipment's footprint, making it particularly suitable for high-density planting environments.

[0053] Through the above technical solutions, this application can directionally improve the ventilation efficiency of the microenvironment at the bottom of the canopy and reduce the probability of condensation on the leaf surface. Vertical laminar flow promotes CO2 transport to areas with dense stomata, improving gas utilization efficiency. The synergistic effect of supplemental lighting and ventilation effectively alleviates the problem of uneven light exposure caused by leaf self-shading.

[0054] When the fan starts, air is drawn in and delivered to the outlet through internal channels of the lamp. Because the outlet is located on the upper surface of the lamp, the airflow is constrained to flow vertically upwards, forming laminar flow. This directional airflow pattern allows the airflow to penetrate the bottom of the plant canopy and directly act on the stomatal distribution area on the underside of the leaves. The fan layout on the side of the lamp avoids spatial interference with the light-emitting components of the supplemental lighting, while simultaneously creating a continuous airflow coverage area.

[0055] Both sides of the lamp 1 are equipped with end caps 3. The contact area between the end caps 3 and the lamp 1 is coated with waterproof silicone or fitted with sealing gaskets to ensure sufficient waterproof sealing. The end caps can be made of injection-molded plastic or metal parts, used to protect the internal components of the lamp and form a complete outer shell. Waterproof silicone refers to an elastic and weather-resistant sealing material, specifically room temperature vulcanizing silicone rubber, which is applied to the contact surface between the end cap and the lamp to form a continuous sealing layer. The sealing gasket is a pre-formed annular sealing element, specifically made of rubber or foam material, which is pressed and fitted between the end cap and the contact surface of the lamp to form physical isolation.

[0056] The end caps are secured to both sides of the lamp fixture with bolts or clips, and the contact surfaces are pre-processed to ensure even distribution of the sealing material. Waterproof silicone is applied to the edges of the end caps using an adhesive dispensing process, forming an elastic sealing layer after curing. The sealing gaskets are embedded inside the end caps through a slotted structure, deforming under pressure during installation to fill the gaps. Both sealing methods prevent external moisture from seeping in through the joint between the end caps and the lamp fixture, avoiding moisture damage to the internal circuitry or fan.

[0057] Example 2

[0058] refer to Figure 1-6As shown, the fan 5 is mounted to the end cover 3 via a fan bracket 9. A housing 8 is fitted around the fan 5, with an air inlet at the bottom corresponding to the fan. The housing 8 is connected to the end cover 3. A fan cover plate 10 can be installed on the bottom of the housing 8 for easy fan maintenance. In this embodiment, the fan 5 is mounted on the side of the output terminal 4. The end cover connected to the fan 5 has a vent 11. The air outlet of the fan 5 is connected to the vent 11. The air generated by the fan enters the lamp 1 through the vent 11 and is discharged from the air outlet 6. The air is discharged vertically from the air outlet, forming a laminar flow vertically upwards. The housing encloses the fan, providing protection, while the bottom air inlet ensures that external air is effectively drawn in. The housing's enclosing structure prevents foreign objects from entering the fan and guides the airflow to concentrate, avoiding efficiency loss caused by airflow dispersion.

[0059] Furthermore, the lamp 1 is equipped with a partition 12, which divides the internal space of the lamp 1 into independent air outlet chambers 13 and heat dissipation chambers 14. The end cap 3 is provided with heat dissipation vents 15, and a breather valve 16 is provided on the lamp 1 corresponding to the area of ​​the heat dissipation chamber. The air outlet 5 is located in the area of ​​the air outlet chamber 13. These independent chambers prevent mutual interference, allowing airflow to form a stable flow path within the lamp 1, reducing airflow diffusion loss, and preventing unguided external air from directly impacting the plant canopy.

[0060] The partition 12 is arranged along the length of the lamp 1, and the air outlet 5 is arranged in a row along the length of the lamp 1, evenly distributed.

[0061] The breather valve 16 is a one-way ventilation device installed in the heat dissipation cavity area. It can be implemented using a rubber diaphragm or a spring-loaded valve structure. Its function is to balance the air pressure difference inside and outside the lamp and prevent moisture from accumulating in the heat dissipation cavity. Opening the breather valve enables heat dissipation.

[0062] In addition, usually one vertical air supply module is sufficient to install on one side of the light fixture. If this is not enough to meet the air supply requirements, one vertical air supply module can be installed on each side of the light fixture.

[0063] Additionally, refer to Figure 7 As indicated, the end cap connected to the housing 8 has a drainage hole 17 corresponding to the area of ​​the air outlet cavity 13, and the housing 8 has a water outlet hole 18. During use, since the air outlet 6 of the lamp faces upwards, rainwater dripping from plants may enter the air outlet cavity 13 inside the housing 1 through the air outlet 6. Once rainwater enters the air outlet cavity 13, if it cannot be drained in time, excessive accumulation will affect the normal use of the lamp. Using the drainage hole 17 and water outlet hole 18, rainwater in the air outlet cavity 13 flows out from the drainage hole 17 into the housing 8, and then exits from the water outlet hole 18 at the bottom of the housing 8, preventing rainwater residue inside the lamp.

[0064] Example 3

[0065] like Figure 1-6 As shown, the lamp 1 is equipped with an environmental sensing module, which is connected to the controller. The environmental sensing module includes a temperature and humidity sensor, a light intensity sensor, and a carbon dioxide sensor. Through these sensors, various data, such as temperature, humidity, light intensity, and carbon dioxide concentration, can be collected in real time. The location of the environmental sensing module is not limited; besides being on the lamp 1, it can also be installed on a fan bracket or a housing.

[0066] Among them, the temperature and humidity sensor refers to the device used to detect the ambient temperature and relative humidity. Specifically, it can be implemented using a digital sensor, which provides the controller with a basis for adjusting the wind speed of the vertical air supply module by collecting data in real time.

[0067] A light intensity sensor is a device used to measure the light conditions at the bottom of the canopy. It can be implemented using a photodiode array and uses feedback signals to control the distribution of supplementary light intensity of the light-emitting components.

[0068] A carbon dioxide sensor is a device that detects the concentration of carbon dioxide in the air. It can be implemented using a non-dispersive infrared sensor or an electrochemical sensor, and the operating parameters of the gas delivery module can be optimized by monitoring the data.

[0069] Specifically, temperature and humidity sensors are positioned near the bottom of the plant canopy to capture microenvironmental data on the underside of leaves. When humidity exceeds a set threshold, the controller activates the vertical airflow module to enhance laminar airflow and accelerate moisture diffusion. A light intensity sensor periodically scans the illuminated areas of the leaves, dynamically adjusting the local supplemental lighting intensity of the light-emitting components to mitigate uneven lighting caused by leaf shading. A carbon dioxide sensor is integrated near the light outlet to monitor the gas concentration in the airflow in real time. When an abnormal concentration gradient is detected, the controller can coordinate with the gas delivery system to adjust the gas supply rate, ensuring effective absorption in areas with dense stomata.

[0070] A controller is an electronic module used to receive and process data collected by the environmental sensing module and control the operation of other components according to preset logic. Specifically, it can be implemented using a microprocessor or an embedded system. The controller dynamically adjusts the working state of the vertical air supply module and the light-emitting component by analyzing environmental data.

[0071] Specifically, the environmental sensing module continuously collects environmental parameters around the luminaire, such as temperature, humidity, light intensity, and carbon dioxide concentration. After receiving this data, the controller analyzes it according to a preset algorithm and adjusts the airflow speed of the vertical air supply module and the brightness of the light-emitting components accordingly. For example, when excessive humidity is detected, the controller can increase the operating power of the vertical air supply module to accelerate airflow; when insufficient light is detected, the controller can increase the output intensity of the light-emitting components. This closed-loop control system achieves dynamic regulation of the microenvironment at the base of the canopy.

[0072] By integrating environmental sensing modules and controllers, proactive regulation based on real-time monitoring data was achieved, effectively solving the problems of lack of dynamic response and delayed environmental intervention in traditional solutions. Real-time monitoring and dynamic regulation of microenvironmental parameters at the base of the canopy were realized, optimizing stomatal opening and closing efficiency and carbon dioxide absorption; proactive intervention in humidity levels reduced the risk of foliar diseases; and the collaborative efficiency of the supplemental lighting and ventilation systems was improved, avoiding energy waste.

[0073] By setting various sensors and coordinating with the controller to control the fan, it is possible to accurately identify high-humidity areas at the bottom of the canopy and trigger directional ventilation, reducing the risk of leaf diseases; by dynamically compensating for the light intensity in the areas shaded by leaves, the photosynthetic efficiency is improved; at the same time, the gas transport path is optimized based on real-time carbon dioxide concentration, reducing gas waste and improving the stomatal absorption rate of dicotyledonous crops.

[0074] The specific working principle of this utility model is as follows:

[0075] 1. Gas diffusion mode

[0076] The fan generates a vertically upward laminar flow, which pushes the CO2-rich air at the bottom through the canopy, creating an "air cushion effect" that reduces the thickness of the blade boundary layer and accelerates the diffusion of gas molecules to the stomata.

[0077] 2. Dynamic control logic

[0078] When the temperature and humidity sensor detects that the relative humidity is higher than 85%, the controller controls the fan to increase the wind speed to a threshold of 1 m / s. When the temperature exceeds 28℃, the maximum wind speed is limited to no more than 0.8 m / s.

[0079] 3. Solar-Wind Synergistic Strategy

[0080] When the light intensity exceeds 300 μmol / m 2 When the wind speed reaches 0.8-1 m / s, the high-speed mode (wind speed 0.8-1 m / s) will be automatically activated to match the gas demand during the peak photosynthesis period.

[0081] 4. Disease prevention model

[0082] When the temperature and humidity probe detects that the relative humidity (RH) at the bottom of the canopy reaches or exceeds 85% for 10 minutes, the control module will trigger the following linkage strategy: increase the fan speed to 2000 rpm (corresponding to a wind speed of 1.2 m / s) to forcibly expel the humid air. If the light intensity is below 100 μmol / m², the control module will also trigger the humid air. 2 / s, the synchronous light-emitting device operates at the lowest power (PPFD 50μmol / m 2 / s), utilizing the photothermal effect to help reduce the humidity on the leaf surface.

[0083] Workflow:

[0084] Based on the above working principle, the entire workflow dynamically adjusts the light, temperature, and humidity environment using a day-night cycle as the baseline. A self-test program is initiated every morning, after which all sensors complete calibration and load preset parameter templates. Supplemental lighting is gradually preheated to the target spectrum, and fans maintain a basic circulation speed. During daytime operation, a tiered control strategy is implemented by real-time monitoring of PPFD, temperature, humidity, and CO2 concentration gradients at the bottom of the canopy: when light intensity is below 200 μmol / m²... 2 The system automatically increases LED power and optimizes light quality ratio at a speed of 0.8-1.2 m / s, while dynamically adjusting the airflow intensity based on vertical wind speed gradient detection to maintain a directional airflow penetrating the canopy. When excessive relative humidity, abnormal temperature, or insufficient CO2 concentration is detected, the light-wind coordinated regulation program is immediately activated. Through phase control linking light intensity adjustment and wind speed, it ensures optimized stomatal opening while preventing leaf dehydration. In the evening, during the disease control period, a strong wind of 1.2 m / s combined with antibacterial spectrum is used for active intervention. At night, it switches to micro-circulation mode to maintain basic environmental parameters. The entire operation cycle utilizes a fuzzy control algorithm to achieve equipment coordination, where wind speed adjustment and supplemental lighting intensity can establish a non-linear coupling relationship. Various trigger conditions can be programmed, and the controller itself has corresponding setting operations; staff only need to access the relevant interface and input the relevant data.

[0085] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
