Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of animal and plant lighting, and in particular to an animal and plant lighting system and method based on periodic light emission. BACKGROUND

[0002] The LED seedling factory is characterized by artificial light for seedling breeding, and the parameters of the artificial light are automatically controlled by a computer. The LED seedling factory is less affected by natural conditions, has strong production planning, short production cycle, and high automation, and can significantly improve the quality, quantity and space utilization of seedling breeding, and is a modern seedling production method developed after greenhouse seedling breeding.

[0003] One of the core technologies of the LED plant seedling factory is the design of the artificial light source system. Through research on the light environment requirements of seedlings, a corresponding artificial seedling LED light source system is developed. For example, the patent document with the publication number CN105165437A discloses a method for promoting tobacco seedling using LED plant growth light source. A fluorescent powder excitation type LED plant growth light source is prepared by combining red light fluorescent powder and blue light chips. The fluorescent powder is an aluminate substrate, a vanadate substrate or a nitride substrate. The fluorescent powder can effectively excite in the wavelength range of 440-470 nm and has obvious emission in the wavelength range of 600-660 nm. The fluorescent powder and organic silicone glue are mixed in a mass ratio of 1:4-20. The invention uses the fluorescent powder excitation LED to not only provide sufficient light for tobacco seedling, but also increase the space growth temperature of tobacco seedling by 2-5℃. On the premise of ensuring or even improving the quality of tobacco seedlings, the time for tobacco seedling is shortened. This method is suitable for greenhouse light supplement and indoor seedling in areas with insufficient light during tobacco seedling period, or for year-round uninterrupted indoor seedling.

[0004] The existing LED seedling factory has the following problems: most of the existing technologies use lamp beads or long strip-shaped light strips to irradiate seedlings, which are limited by the light-emitting angle of the light source, resulting in most plant positions being relatively inclined to the light source, so that the seedlings are prone to uneven growth and abnormal posture due to phototaxis. In addition, since plants have light and dark periods, the lighting source emits light periodically in a manner corresponding to the light cycle of the seedlings. During the light period, the lighting source irradiates the seedlings to promote their growth, and during the dark period, the lighting source is turned off. When the lighting source is turned off, nocturnal pests become active, and the seedlings are easily damaged by pests. Although some existing technologies propose a technical solution of setting part of the pest control lamp beads in the middle of the lighting promotion lamp beads to inhibit pest activity during the dark period of the plants, most of the existing pest control lamps use yellow-green light, which will inhibit the growth of most green plants, thereby prolonging the seedling time, and replacing the lamp beads for promoting seedling growth with pest control lamp beads will inevitably weaken the promotion effect.

[0005] Therefore, how to improve seedling growth while controlling pests is the technical problem that this invention aims to solve.

[0006] To address the shortcomings of existing technologies, this invention provides a periodic illumination system and method for plants and animals. The system includes a surface light source to promote seedling growth and a point light source to inhibit pest activity. The surface light source can adjust different illumination cycles to suit the growth needs of different plant seedlings, improving the productivity of plant tissues. Simultaneously, by adjusting the size and shape of the light spot to suit different plants, it illuminates the area where the plant is located, avoiding light energy waste caused by the light source illuminating uncovered areas, thus improving the energy efficiency of the light source. Furthermore, the system vertically positions the light source above the plant to provide uniform illumination, preventing tilting growth due to phototropism that affects the plant's appearance. The point light source emits light during the seedling's dark period, illuminating the soil and inhibiting pest activity, thereby increasing the yield of high-quality seedlings.

[0007] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a periodic emission-based lighting system for plants and animals. The lighting system includes an illumination panel, an image detection unit, and a control unit. The illumination panel comprises several adjacent, spliced ​​surface light sources and point light sources positioned at the splicing nodes of the surface light sources. The illumination panel and the image detection unit are respectively connected to the control unit via wired and / or wireless means. The image detection unit acquires an image containing the illuminated object and transmits the image to the control unit. The control unit analyzes the growth state of the illuminated object based on the image and sends a corresponding emission command to the illumination panel. The illumination panel controls the emission mode of the surface light sources and the point light sources based on the emission command.

[0009] Preferably, the surface light source emits growth-promoting light perpendicularly to the irradiated object in a photoperiod adapted to the current growth state of the irradiated object. Preferably, the point light source can emit pest-suppressing light obliquely irradiating the area near the irradiated object in a rotatable manner. Preferably, the luminescence command includes one or a combination of luminescence position, luminescence intensity, and luminescence period.

[0010] Preferably, for plant seedlings, the surface light source of the present invention forms an illumination area adapted to the plant leaves by splicing together, and by providing vertical light, it avoids the plant from growing at an angle due to its position relative to the light source. In addition, the present invention also uses a point light source to illuminate the area near the plant with insect-repelling light to suppress pest activity, thereby preventing pests from eating the seedlings and improving the yield of high-quality seedlings.

[0011] According to a preferred embodiment, the control unit is configured with a processor and a historical database. The historical database stores the optimal photoperiods for various growth stages of different irradiated objects. The processor determines the type of irradiated object and its current growth stage based on the image. In response to the determination of the type of irradiated object and its current growth stage, the processor filters photoperiods suitable for the current growth state of the irradiated object from the historical database.

[0012] Preferably, the present invention determines the current growth state of the irradiated object through the image, thereby determining the photoperiod that promotes the development of a certain feature of the irradiated object.

[0013] According to a preferred embodiment, the processor further confirms the geometric and positional parameters of the illuminated portion of the irradiated object based on the image, and the processor determines the combination of the surface light source and the point light source participating in periodic light emission on the illumination plate based on the geometric and positional parameters of the illuminated portion of the irradiated object. Preferably, the combination enables the surface light source to vertically illuminate the irradiated object and the illumination area formed by the surface light source to be adapted to the geometric size of the irradiated object. Preferably, the combination enables the point light source to obliquely illuminate areas other than the illuminated portion of the irradiated object for pest control.

[0014] According to a preferred embodiment, the image further includes a platform carrying the illuminated object. Preferably, the image detection unit uses the entire platform as the image background when acquiring the image. The processor performs region segmentation on the image of the illuminated object acquired by the image detection unit based on the setting of the surface light source on the illumination board, and the segmented region is mapped to the surface light source.

[0015] According to a preferred embodiment, the processor filters out regions in the image that overlap with the illuminated object, and determines a combination of surface light sources on the illumination panel based on the regions that overlap with the illuminated object.

[0016] According to a preferred embodiment, the processor is capable of determining a combination of point light sources distributed along the edges of the combination of surface light sources based on the combination of surface light sources. The processor adjusts the tilt angle of the point light sources based on the geometric parameters of the irradiated object, so that the point light sources illuminate areas of the irradiated object other than the light-receiving portion, for pest control.

[0017] According to a preferred embodiment, the processor determines the overlap ratio between the illuminated object and the cut-out region based on the geometric parameters of the illuminated object and the region segmentation of the image. Preferably, if the overlap ratio exceeds a threshold, a surface light source corresponding to the cut-out region participates in the illumination.

[0018] According to a preferred embodiment, the surface light source and the point light source participating in the illumination alternately emit light based on the light emission command. Preferably, the emission period of the surface light source and the point light source is the same, and the emission states of the surface light source and the point light source are complementary within a single cycle.

[0019] This invention also provides a method for illuminating plants and animals based on periodic emission. The method includes:

[0020] A lighting panel is composed of several adjacent spliced ​​surface light sources and point light sources set at the splicing nodes of the surface light sources;

[0021] An image is acquired by the image detection unit, using the entire platform as the image background and including the illuminated object, and the image is transmitted to the control unit.

[0022] The control unit analyzes the growth state of the irradiated object based on the image and sends a light emission command corresponding to the growth state to the illumination panel;

[0023] The lighting panel controls the light emission mode of the surface light source and the point light source based on the light emission command.

[0024] Preferably, the surface light source emits growth-promoting light that vertically illuminates the irradiated object in a manner that adapts to the photoperiod of the current growth state of the irradiated object, and the point light source can emit pest-inhibiting light that tilts to illuminate the area near the irradiated object in a rotatable manner.

[0025] According to a preferred embodiment, the method further includes:

[0026] Based on the surface light source setting on the illumination board, the image of the illuminated object acquired by the image detection unit is segmented into regions, and the segmented regions are mapped to the surface light source;

[0027] Based on the image, the geometric and positional parameters of the illuminated portion of the object are confirmed.

[0028] The regions that overlap with the illuminated object are selected from the image, and the combination of the surface light sources on the illumination panel is determined based on the regions that overlap with the illuminated object.

[0029] The combination of point light sources distributed along the edge of the combination of surface light sources is determined based on the combination of surface light sources. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figures 1 to 7 Please provide a detailed explanation.

[0040] This invention provides a plant and animal lighting system based on periodic emission. The lighting system includes a lighting panel, an image detection unit, and a control unit. The lighting panel includes several adjacent, spliced ​​surface light sources and point light sources positioned at the splicing nodes of the surface light sources. The surface light sources of this invention form an illumination area adapted to the plant leaves through splicing, and by providing vertical light, it prevents the plant from growing at an angle due to its relative position to the light source. Furthermore, this invention also uses insect-repellent light from the point light sources to illuminate the area near the plant to suppress pest activity, thereby preventing pests from eating seedlings and improving the seedling yield.

[0041] Example 1

[0042] The quality of seedlings is undoubtedly a key factor determining crop yield and quality. In modern seedling factories, fluorescent tubes or LED lights are typically used to provide the necessary illumination to promote healthy seedling growth. Once installed, these lights are usually not frequently replaced but are used continuously to maintain a stable light environment. However, over time, the morphology of the plants gradually changes, which inevitably affects the uniformity of light.

[0043] In the initial stages, even if the light source can evenly illuminate the plant, the distribution of light will become uneven as the plant grows and its shape changes. This uneven light distribution, coupled with the plant's natural phototropism (the tendency to grow towards the light source), can easily lead to uneven growth of the light-receiving parts of the plant, and may even result in deformities. Furthermore, since the angle of light emission from the light source is usually fixed, this limits the coverage area of ​​the light, causing many plants to tilt relative to the light source, further exacerbating the uneven growth problem caused by phototropism in seedlings.

[0044] Plant growth requires a specific photoperiod, consisting of a light period and a dark period. During the light period, plants accumulate nutrients through photosynthesis, and during the dark period, they transport these accumulated nutrients. Studies have shown that under prolonged continuous light, the products of photosynthesis cannot be transported in a timely manner, leading to a large accumulation of nutrients. This damages the plant's photosynthetic organs, reduces its photosynthetic capacity, and hinders plant growth. Therefore, setting the light source's emission period according to the plant's photoperiod is essential.

[0045] Plant photoperiods consist of a light period and a dark period, and the lighting source emits light periodically in accordance with the seedling's photoperiod. During the light period, the lighting source illuminates the seedling to promote its growth, and during the dark period, the lighting source is turned off. When the lighting source is off, nocturnal pests become active, and the seedlings are highly susceptible to damage from them. Most existing insect-repelling lamps use yellow-green light, which inhibits the growth of most green plants. Directly illuminating the plants with insect-repelling lamps would prolong the seedling stage.

[0046] To address the shortcomings of existing technologies, this embodiment provides a plant and animal lighting system 100 based on periodic emission. See also... Figure 1 and Figure 7 The lighting system 100 includes a lighting panel 110, an image detection unit 120, and a control unit 130. The lighting panel 110 provides periodic illumination to the object 200 placed on the platform 140. Its main function is to adjust the intensity, color, and period of the illumination according to the light emission commands sent by the control unit 130 to meet the growth requirements of the object 200. The image detection unit 120 acquires images of the object 200. Through a camera or other image acquisition device, it captures changes in the appearance of the object 200 in real time, providing analysis data to the control unit 130. The control unit 130, as the core of the system, receives image data transmitted by the image detection unit 120, analyzes the growth state of the object 200, and generates corresponding light emission commands based on the analysis results to control the operation of the lighting panel 110.

[0047] The lighting panel 110 and the control unit 130 establish a communication connection via wired and / or wireless means. This connection allows the control unit 130 to send illumination commands to the lighting panel 110 and may receive status feedback from the lighting panel 110. Similarly, the image detection unit 120 establishes a communication connection with the control unit 130 via wired and / or wireless means. This connection enables the image detection unit 120 to transmit acquired image data to the control unit 130 for processing.

[0048] Specifically, the image detection unit 120 acquires images of the irradiated object 200 and transmits these image data to the control unit 130 via wired or wireless means. Upon receiving the image data, the control unit 130 performs image analysis to identify the growth status of the irradiated object 200, such as growth rate and health condition. Based on the analysis results, the control unit 130 generates corresponding light emission commands and sends them to the lighting board 110 via wired or wireless means. Upon receiving the light emission commands, the lighting board 110 adjusts its light emission mode (such as emission position, light intensity, color, and period) to periodically irradiate the irradiated object 200 placed on the carrying platform 140 to promote its growth.

[0049] See Figure 2 and Figure 3 The lighting panel 110 includes several adjacently spliced ​​surface light sources 111 and point light sources 112 disposed at the splicing nodes of the surface light sources 111. The placement of point light sources 112 at the splicing nodes of the surface light sources 111 can further improve the uniformity and flexibility of illumination. The point light sources 112 can be used to supplement any potential illumination blind spots of the surface light sources 111, or to provide additional illumination intensity in specific areas.

[0050] Preferably, the surface light source 111 can be an equilateral triangle structure. Preferably, several surface light sources 111 are joined together to form an illumination plane. For example... Figure 3 As shown, six surface light sources 111 are arranged circumferentially with the same vertex as the center, forming a hexagonal surface light source. A point light source 112 is located at the center of the hexagonal light source. Two surface light sources 111 are arranged opposite each other with a common side, forming a rhombus-shaped surface light source. Four surface light sources 111 are arranged to form an equilateral triangle surface light source. Three surface light sources 111 are joined together to form a half-hexagonal surface light source. Preferably, when a single surface light source 111 emits light, it can form a triangular illumination area on the platform 140, and the parallel light emitted by the surface light source 111 illuminates the triangular illumination area perpendicularly. Preferably, the illumination plane formed by joining several surface light sources 111 can emit light covering the entire platform 140. Because the surface light sources 111 adopt an equilateral triangle structure, they can form illumination planes of various shapes through different combinations. This flexibility allows the system to adjust the distribution of the light sources according to the shape and size of the illuminated object 200 and the specific layout of the platform 140, thereby achieving precise control of the illumination position. Each surface light source 111 emits parallel light that illuminates the triangular illumination area perpendicularly, ensuring uniform illumination. When several surface light sources 111 are combined to form an illumination plane covering the entire platform 140, it ensures that the object 200 receives uniform illumination from directly above, avoiding uneven illumination caused by tilted light sources. The arrangement of the surface light sources 111 can be adjusted according to the growth needs of the object 200. For example, for areas requiring more light, the number of surface light sources 111 in that area can be increased or their luminous intensity adjusted. This highly adaptable design helps optimize illumination conditions and promotes the healthy growth of the object 200. By precisely controlling the illumination position, unnecessary energy waste can be avoided. The surface light sources 111 directly illuminate the area requiring light, reducing light scattering and reflection losses and improving illumination efficiency. The arrangement of the surface light sources 111 also gives the system good scalability. As the irradiated object 200 grows or the platform 140 expands, the surface light source 111 can be easily added or reconfigured to adapt to new lighting requirements. Preferably, such as Figure 3 As shown, the lighting panel 110 controls the emission mode of the surface light source 111 and the point light source 112 based on emission commands. Preferably, the surface light source 111 emits growth-promoting light perpendicularly to the irradiated object 200 in a manner adapted to the photoperiod of the current growth state of the irradiated object 200. Preferably, the point light source 112 can emit pest-suppressing light obliquely to the area near the irradiated object 200 in a rotatable manner. Preferably, the emission commands include one or a combination of one or more of the following: emission position, emission intensity, and emission period.

[0051] Preferably, such asFigure 7 As shown, the control unit 130 is equipped with a processor 131 and a historical database 132. The historical database 132 stores the optimal photoperiods for each growth stage of various irradiated objects 200. The processor 131 identifies the type of irradiated object 200 and its current growth stage based on an image. In response to the determination of the type of irradiated object 200 and its current growth stage, the processor 131 selects photoperiods suitable for the current growth state of the irradiated object 200 from the historical database 132.

[0052] For example, lighting system 100 can be used to grow lettuce. Lettuce is a leafy vegetable with specific requirements for light intensity and frequency.

[0053] Image detection unit 120 periodically acquires images of lettuce plants and transmits these images to control unit 130. Processor 131 analyzes the images to identify the type of lettuce and its current growth stage (e.g., germination, seedling, growth, or maturity). Based on the identified lettuce type and current growth stage, processor 131 selects photoperiods suitable for the lettuce's current growth state from historical database 132. Processor 131 generates emission instructions, including the emission positions, emission intensities, and emission periods of surface light source 111 and point light source 112.

[0054] For surface light source 111, the instruction is set to emit growth-promoting light that vertically illuminates the lettuce plants, with a light intensity of 2000 lux, a light duration of 16 hours per day, and the use of full-spectrum LED lights to adapt to the photoperiod of the lettuce's current growth state.

[0055] For point light source 112, the instruction is set to emit pest-suppressing light that tilts and illuminates the area near the lettuce plant in a rotatable state, with a light intensity of 500 lux, a lighting time of 2 hours per day, and the use of a specific wavelength of UV-A light to prevent the occurrence and spread of pests.

[0056] Processor 131 analyzes the specific location and density of the lettuce plants to determine the optimal combination shape and position of the surface light sources 111. If the lettuce plants are denser in the central area of ​​the lighting panel 110, processor 131 may instruct adjustments to the combination shape of the surface light sources 111, such as adjusting them to a denser hexagonal arrangement, to ensure that the lettuce plants in the central area receive sufficient light. If the lettuce plants are sparser at the edges of the lighting panel, processor 131 may instruct adjustments to the combination position of the surface light sources 111, such as controlling the emission of some surface light sources 111 in the edge areas, to balance the light distribution throughout the planting area.

[0057] The lighting panel 110 receives and executes the light emission command, and the surface light source 111 and the point light source 112 adjust their light emission modes according to the command. The surface light source 111 provides uniform vertical illumination, promoting the healthy growth of lettuce plants. The point light source 112 provides pest-suppressing light in specific areas, reducing the impact of pests on lettuce plants.

[0058] The lighting system 100 continuously monitors the growth status of the lettuce plants and adjusts the light emission commands as needed to ensure that the light conditions are always optimal. Preferably, the present invention determines the current growth status of the irradiated object 200 through images, thereby determining the photoperiod that promotes the development of a certain feature of the irradiated object 200.

[0059] Preferably, the processor 131 further confirms the geometric and positional parameters of the illuminated portion of the irradiated object 200 based on the image acquired by the image detection unit 120, and the processor 131 determines the combination of the surface light source 111 and the point light source 112 participating in periodic light emission on the lighting panel 110 based on the geometric and positional parameters of the illuminated portion of the irradiated object 200. Preferably, the combination enables the surface light source 111 to vertically illuminate the irradiated object 200, and the illumination area formed by the surface light source 111 is adapted to the geometric size of the irradiated object 200. Preferably, the combination enables the point light source 112 to obliquely illuminate areas of the irradiated object 200 other than the illuminated portion, for pest control.

[0060] For example, the light scheme for strawberry seedlings by processor 131 is shown in Table 1.

[0061] Germination period: Strawberry seeds need gentle and even light to promote germination. The light intensity should not be too high to avoid overheating the seeds.

[0062] Seedling stage: Seedlings need more light to promote leaf development and root growth. The light intensity should be moderate to support rapid seedling growth.

[0063] Growing season: Strawberry plants grow rapidly during this stage and require ample sunlight to support leaf expansion and overall plant growth. High light intensity is necessary to meet the plant's energy needs.

[0064] Flowering period: Strawberries need ample sunlight to promote flower bud formation and healthy flower opening. Light intensity should be further increased to support flower development and pollination.

[0065] Fruiting stage: Strawberries require the highest intensity of sunlight to support fruit ripening and sugar accumulation. Maximum light intensity should be maintained to maximize fruit quality and yield.

[0066] Table 1 Lighting schemes for strawberry seedlings at different stages

[0067]

[0068] Germination period: Use a hexagonal surface light source to provide uniform basic lighting, and a central point light source to enhance the light intensity in the seed germination area.

[0069] Seedling stage: Switch to a diamond-shaped surface light source to provide more concentrated light, promoting rapid seedling growth and leaf development. Corner spot light sources are used for pest control.

[0070] During the growing season: An equilateral triangular surface light source is used to provide broad and uniform illumination, supporting the overall growth of strawberry plants. Corner spot light sources continue to be used for pest control.

[0071] During the flowering period: Adjust to a semi-hexagonal surface light source to ensure that the light is concentrated on the upper part of the plant, which is conducive to flower formation and pollination. Corner spot light sources are used for pest control.

[0072] Fruiting stage: Revert to using hexagonal surface light sources to provide uniform and intense illumination, ensuring all fruits receive sufficient light to promote ripening and sugar accumulation. A central point light source is used to enhance light intensity in the ripening area.

[0073] Preferably, the image further includes a platform 140 that carries the illuminated object 200. Preferably, when the image detection unit 120 acquires the image, it uses the entire platform 140 as the image background. The processor 131 performs region segmentation on the image of the illuminated object 200 acquired by the image detection unit 120 based on the setting of the light source 111 on the illumination plate 110, and the segmented region is mapped to the surface light source 111.

[0074] Preferably, the shape of the illumination plane formed by splicing several surface light sources 111 is the same as the shape of the platform 140. Preferably, the control unit 130 assigns a unique code to each surface light source 111. Preferably, the control unit 130 acquires the light spot shape and code of each surface light source 111 that makes up the illumination plane. The control unit 130 generates a segmentation basis image according to the actual splicing method of the surface light sources 111. Preferably, the segmentation basis image has the same shape as the illumination plane, and each surface light source 111 in the segmentation basis image corresponds one-to-one with the actual surface light source 111. That is, the position and splicing relationship of a certain surface light source 111 in the segmentation basis image are the position and splicing relationship of the surface light source 111 corresponding to its code on the actual illumination plane. Preferably, each surface light source 111 in the segmentation basis image corresponds to an actual surface light source 111.

[0075] Preferably, the size of the segmentation basis image is the same as the size of the image acquired by the image detection unit 120. Preferably, the control unit 130 overlays the segmentation basis image onto the image acquired by the image detection unit 120 to segment the image acquired by the image detection unit 120. Preferably, the area where the image acquired by the image detection unit 120 overlaps with a certain light source 111 in the segmentation basis image is the area on the actual illumination plane where the light source 111 illuminates the platform 140 corresponding to the image acquired by the image detection unit 120.

[0076] For example, the image detection unit 120 begins acquiring images, ensuring the entire platform 140 serves as the image background. The illuminated object 200 is placed on the platform 140, and the image detection unit 120 captures its image. The control unit 130 generates a segmentation reference image based on the position, spot shape, and code of each surface light source 111. The shape of the segmentation reference image is the same as the shape of the illumination plane (composed of several surface light sources 111), and its size is consistent with the size of the image acquired by the image detection unit 120. The position and splicing relationship of each surface light source 111 in the segmentation reference image correspond one-to-one with the position and splicing relationship on the actual illumination plane. The control unit 130 overlays the generated segmentation reference image onto the image acquired by the image detection unit 120. Based on the segmentation reference image, the acquired image is segmented into regions, ensuring that each segmented region maps to the corresponding surface light source 111.

[0077] The image acquired by the image detection unit 120 overlaps with the area of ​​a light source 111 in the image based on the segmentation criteria. This area is identified as the illumination area corresponding to the light source 111 on the actual illumination plane. The illuminated object 200 within each illumination area is analyzed and processed, including feature extraction and size measurement. The processing results are output, including relevant data and an analysis report of the illuminated object 200. Based on the processing results, the settings of each light source 111 on the illumination panel 110 are adjusted to optimize the illumination effect, thereby improving image quality and processing accuracy.

[0078] Preferably, the processor 131 filters out regions that overlap with the illuminated object 200 from the image acquired by the image detection unit 120, and determines the combination of light sources 111 on the illumination panel 110 based on the regions that overlap with the illuminated object 200.

[0079] For example, the following method can be used to determine overlapping regions in an image:

[0080] Images are acquired using the image detection unit 120.

[0081] The acquired images are preprocessed, such as denoising, contrast enhancement, and grayscale conversion, to improve the accuracy of subsequent image processing.

[0082] Image processing algorithms (such as edge detection and morphological processing) are used to identify the illumination area of ​​the surface light source 111 in the image. The boundary or center position of the surface light source 111 is marked.

[0083] The illuminated object 200 is identified using image segmentation techniques (such as thresholding, region growing, etc.). The outline or region of the illuminated object 200 is then marked.

[0084] The boundary or center position of the illumination of the surface light source 111 is compared with the outline or area of ​​the illuminated object 200.

[0085] For example, the intersection of the area of ​​the surface light source 111 and the area of ​​the illuminated object 200 can be calculated; the intersection area is the overlapping area. Alternatively, the shortest distance from the boundary of the surface light source 111 to the boundary of the illuminated object 200 can be measured; if it is less than a certain set threshold, then overlap is considered to exist. Or, the area overlap rate between the area of ​​the surface light source 111 and the area of ​​the illuminated object 200 can be calculated; if the overlap rate exceeds a certain threshold (e.g., 50%), then overlap is determined.

[0086] Based on the location and size of the overlapping areas, the corresponding combination of surface light sources 111 on the lighting panel 110 is determined. Through the above steps, overlapping areas in the image can be effectively identified, and the lighting effect can be optimized based on this information.

[0087] like Figure 3 The image shows the combined effects of several different surface light sources 111. Preferably, Figure 3 The shaded areas are the illuminated areas formed by different combinations of surface light sources 111.

[0088] Preferably, the irradiated object 200 can be a plant such as cucumber, tomato, or *Pseudostellaria heterophylla*. Preferably, the lighting system 100 of this embodiment can be used for seedling illumination of *Pseudostellaria heterophylla*. Preferably, after the *Pseudostellaria heterophylla* seeds 201 germinate and sprout, they are transplanted into the cultivation soil 202 for seedling cultivation under illumination. Preferably, the cultivation soil 202 is laid on the carrying platform 140, and there is a certain preset interval between the *Pseudostellaria heterophylla* seeds 201. Preferably, the preset interval is set according to the size of the mature *Pseudostellaria heterophylla* seedlings to ensure that different plants will not interfere with each other before the seedling cultivation is completed (e.g., the leaves of different plants will block each other).

[0089] Preferably, the image detection unit 120 acquires images of the carrier platform 140. The control unit 130 analyzes the growth state of the Codonopsis pilosula based on the images acquired by the image detection unit 120, confirms the geometric and positional parameters of its light-receiving part, and thus determines the combination and emission period of the surface light source 111 participating in the periodic emission on the illumination plate 110.

[0090] Preferably, the control unit 130 performs region segmentation on the image acquired by the image detection unit 120 based on the setting of the light source 111 on the illumination panel 110. See also Figure 4 Preferably, the control unit 130 divides the image acquired by the image detection unit 120 into several triangular regions, and each triangular region has a unique corresponding surface light source 111 on the illumination panel 110. Preferably, the control unit 130 determines whether the surface light source 111 corresponding to the triangular region participates in illumination by identifying whether there is *Gynostemma pentaphyllum* in the divided triangular region. When there is at least one *Gynostemma pentaphyllum* in the triangular region, the surface light source 111 corresponding to the triangular region participates in illumination.

[0091] Preferably, the control unit 130 extracts an image of the *Pseudostellaria heterophylla* from the triangular region and compares the extracted image with historical data in the historical database 132 to determine the current growth stage of the *Pseudostellaria heterophylla* and the optimal photoperiod for that growth stage. Preferably, the surface light source 111 that participates in the illumination provides illumination according to the optimal photoperiod for the current growth stage of the *Pseudostellaria heterophylla*, so that the light-receiving part of the *Pseudostellaria heterophylla* absorbs light energy to promote growth and development. For example, when the control unit 130 determines, by comparing with the historical database 132, that the *Codonopsis pilosula* is in the seed germination stage and its optimal photoperiod is 16 hours (12 hours of light and 4 hours of darkness), the surface light source 111 corresponding to the area where the *Codonopsis pilosula* seed 201 is located emits light for a period of 16 hours, emitting light for 12 hours within a cycle and not emitting light for the remaining 4 hours. This allows the *Codonopsis pilosula* seed 201 to grow at the optimal growth rate. This not only avoids the *Codonopsis pilosula* seed 201 from failing to accumulate enough nutrients due to insufficient photosynthesis time, leading to poor plant development, but also avoids the *Codonopsis pilosula* seed 201 from failing to accumulate enough nutrients due to excessive photosynthesis time, leading to damage to the organs of the *Codonopsis pilosula* seed 201 that are performing photosynthesis, thus affecting plant growth.

[0092] The surface light source 111 provides illumination adapted to the current photocycle of *Pseudostellaria heterophylla* in an alternating light-dark pattern. While this promotes the seedling process, nocturnal pests become active when the surface light source 111 is not emitting light, making *Pseudostellaria heterophylla* highly susceptible to damage. Since seedlings are more fragile and less resistant to pests than mature plants, damage can lead to slowed development or even death. Furthermore, to reduce pesticide residues, pesticides should be used sparingly or not at all during the seedling stage. Therefore, this invention uses light to repel pests, inhibiting their activity and thus controlling pests. Existing insect-repelling lights mostly use yellow-green light, but direct exposure to yellow-green light inhibits the growth of most green plants. For *Pseudostellaria heterophylla*, direct exposure to yellow-green light during seedling cultivation will inhibit budding, rooting, and flowering.

[0093] Preferably, Figure 5 and Figure 6 As shown, in this embodiment, a point light source 112 capable of emitting insect-repelling light is provided at the junction of the surface light source 111. The insect-repelling lighting scheme for Codonopsis pilosula is shown in Table 2.

[0094] Table 2: Illumination scheme for point light source 112 of Codonopsis pilosula

[0095]

[0096] As shown in Table 2, yellow-green light is used during the germination and seedling stages because this spectrum has less inhibitory effect on the growth of *Pseudostellaria heterophylla* and is effective in repelling pests. Full-spectrum light is used during the growing, flowering, and fruiting stages to support the overall growth and development of *Pseudostellaria heterophylla* and protect flowers and fruits from pests. The irradiation time and duration are adjusted according to the light requirements of different growth stages of *Pseudostellaria heterophylla* and the activity characteristics of pests.

[0097] Preferably, the processor 131 is capable of determining a combination of point light sources 112 distributed along the combined edge of the surface light sources 111 based on the combination of surface light sources 111. The processor 131 can adjust the tilt angle of the point light sources 112 based on the geometric parameters of the irradiated object 200, so that the point light sources 112 illuminate the area of ​​the irradiated object 200 other than the illuminated part, for pest control.

[0098] See Figure 5 The surface light sources 111 participating in the illumination form an illumination area. Point light sources 112 at the edge of the illumination area participate in insect-repelling luminescence, while point light sources 112 outside and inside the illumination area do not emit light during seedling cultivation. Preferably, the point light sources 112 located at the edge of the illumination area adjust their luminescence angle by rotating to provide insect-repelling illumination to the soil near the roots of the Codonopsis pilosula.

[0099] See Figure 6Preferably, at least three point light sources 112 form an insect-repelling lighting area 203 in the region near the root of the *Codonopsis pilosula* seed 201. Preferably, the insect-repelling lighting areas 203 formed by the point light sources 112 overlap. Preferably, the insect-repelling lighting area 203 formed by at least three point light sources 112 includes the *Codonopsis pilosula* seed 201, thereby suppressing pest activity in the area near the *Codonopsis pilosula* seed 201. Preferably, since the *Codonopsis pilosula* seed 201 is in a germinating state and has few leaves, the point light sources 112 can avoid the leaves when illuminating at an angle, thereby reducing the inhibition on the development of the *Codonopsis pilosula* seed 201. Preferably, since the insect-repelling light can only suppress or repel pests but not kill them, this embodiment sets an insect-repelling lighting area within the lighting area formed by the combination of surface light sources 111 to drive pests to areas not illuminated by the point light sources 112, ensuring that pests do not come into contact with the plant because they do not have hiding areas (shaded areas, dark areas).

[0100] Preferably, although the point light source 112 still uses yellow-green light, when the point light source 112 is tilted to illuminate the *Pseudostellaria heterophylla* seeds 201, the light does not reach the leaves of the *Pseudostellaria heterophylla*. The part of the *Pseudostellaria heterophylla* illuminated by the insect-repellent lamp is the non-photosensitive white stem part; in other words, under these conditions, the *Pseudostellaria heterophylla* does not receive yellow-green light, meaning that the light from the point light source 112 will not inhibit the growth of the *Pseudostellaria heterophylla*. Table 3 shows exemplary parameters of the tilt angle of the point light source 112.

[0101] Table 3: Tilt Angle of Point Light Source 112

[0102]

[0103] Germination period:

[0104] Point light source 112A: tilted at 45°, mainly illuminating the soil on the left side of the roots.

[0105] Point light source 112B: tilted at 45°, mainly illuminating the soil on the right side of the roots.

[0106] Point light source 112C: tilted at 55°, mainly illuminating the soil in the center of the root zone.

[0107] Seedling stage: As the seedling leaves unfold, it may be necessary to adjust the tilt angle of the point light source 112 to avoid direct irradiation of the leaves.

[0108] Point light source 112A: Adjust to 35° and illuminate the soil on the left side of the seedling roots.

[0109] Point light source 112B: Adjust to 30° and illuminate the soil on the right side of the seedling roots.

[0110] Point light source 112C: Adjust to 40° and illuminate the soil in the center of the seedling roots.

[0111] Leaf formation stage: The tilt angle of point light source 112 needs to be carefully adjusted according to the specific distribution and size of the leaves of *Codonopsis pilosula*. For example, if the leaves are mainly distributed on the left side, point light source 112A may need to be adjusted to 10° to illuminate the soil on the right side. If the leaves are small and sparsely distributed, point light sources 112B and 112C may need to be adjusted to 25° and 35° respectively to ensure that the roots receive sufficient illumination without directly illuminating the leaves.

[0112] When the leaves of *Codonopsis pilosula* sprout, in the image acquired by the image detection unit 120, the leaves may cross triangular regions identified by two different control units 130. Only a portion of each leaf exists within the triangular region identified by the control unit 130. Preferably, the control unit 130 determines whether the surface light source 111 corresponding to the triangular region participates in illumination based on the overlap ratio between the aforementioned partial leaves and the triangular region.

[0113] Preferably, the processor 131 determines the overlap ratio between the illuminated object 200 and the cut-out region based on the geometric parameters of the illuminated object 200 and the region segmentation of the image. Preferably, if the overlap ratio exceeds a threshold, the area light source 111 corresponding to the cut-out region participates in illumination.

[0114] Preferably, when the control unit 130 identifies the leaves of the Codonopsis pilosula and the edge of the leaves is located in a separate triangular area, if the processor 131 identifies that the area of ​​the Codonopsis pilosula in the triangular area exceeds 30% of the triangular area, the surface light source 111 corresponding to the triangular area participates in the illumination.

[0115] Example 2

[0116] This embodiment is a further improvement on embodiment 1, and repeated content will not be described again.

[0117] In nature, sunlight is a multi-spectral light source, providing both signal and energy light necessary for plant growth. Existing plant factories often use monochromatic or combined light. The wavelengths and proportions of these artificial light sources are often designed to meet the dry matter accumulation requirements of plant growth, neglecting the most crucial aspect of plant life—photomorphogenesis. Throughout the plant's growth cycle, light's role in plant growth includes photosynthesis and signaling. Photosynthesis primarily provides matter and energy to the plant and is known as the high-energy response. Signaling, which is involved in plant morphogenesis, is known as the low-energy response. Specifically, the main process of the low-energy response is as follows: Light, acting as a signal, shines on the plant leaves. Photoreceptors on the leaves receive the signal and transduce it. Primary reactions occur within the leaves, and regulatory pathways are selected based on the type of photoreceptor that received the signal, selectively promoting the development of a particular trait in the plant.

[0118] Preferably, the surface light source 111 of the present invention can employ a hybrid light source for seedling illumination, providing both energy light and signal light. Preferably, the surface light source 111 may include red LEDs, green LEDs, blue LEDs, and a diffuser layer. The diffuser layer is typically used as a housing or part of the housing of the surface light source 111 in optical devices and lighting systems to improve the distribution and uniformity of light. In the surface light source 111, the diffuser layer disperses and homogenizes the light from the red, green, and blue LEDs, making the light emitted from the light source more uniform, reducing or eliminating light spots and hot spots, and improving the overall quality of the lighting effect. Thus, the light emitted from the LEDs first passes through the diffuser layer and then reaches the target area. Preferably, the surface light source 111 mixes the number of red, green, and blue LEDs involved in the light emission to create a light source including both energy light and signal light, which is then perpendicularly irradiated onto the irradiated object 200 through the diffuser layer. Common materials for the diffuser layer include polycarbonate (PC), polymethyl methacrylate (PMMA), and glass.

[0119] Preferably, the surface light source 111 and the point light source 112 participating in the illumination emit light alternately based on the light emission command. Preferably, the light emission period of the surface light source 111 and the point light source 112 is the same, and the light emission state of the surface light source 111 and the point light source 112 is complementary within a single cycle.

[0120] When the surface light source 111 provides growth-promoting light to the irradiated object 200, the point light source 112 does not emit light. When the surface light source 111 stops providing growth-promoting light to the irradiated object 200, the point light source 112 emits pest-inhibiting light.

[0121] Studies have shown that freesia exhibits the fastest callus and bud differentiation rate, the highest bud differentiation rate and biomass, and the most numerous leaves and best growth under white light. Taking freesia as an example, when it is necessary to promote bud differentiation, the surface light source 111 uses a mixture of equal numbers of red, green, and blue LEDs to form white light to promote freesia bud differentiation. Preferably, after the photoperiod of the freesia ends, the surface light source 111 turns off most of the LEDs, retaining only a portion of the LEDs used as signal light to emit light.

[0122] Preferably, since the surface light source 111 emits white light during the photoperiod, which can suppress the activity of nocturnal pests instead of sunlight, the point light source 112 does not emit light during the photoperiod. Preferably, during the darkperiod, the surface light source 111 emits only a weak white light as a signal light for the freesia. At this time, the light emitted by the surface light source 111 is insufficient to suppress the activity of nocturnal pests, so the point light source 112 emits insect-repelling light to prevent pests from damaging the plant.

[0123] Example 3

[0124] This embodiment is a further improvement on Embodiments 1 and 2, and the repeated content will not be described again.

[0125] This embodiment provides a method for illuminating plants and animals based on periodic emission, including:

[0126] A lighting panel 110 is composed of several adjacent spliced ​​surface light sources 111 and point light sources 112 set at the splicing nodes of the surface light sources 111;

[0127] The image detection unit 120 acquires an image with the entire platform 140 as the image background and including the illuminated object 200, and transmits the image to the control unit 130.

[0128] The control unit 130 analyzes the growth state of the irradiated object 200 based on the image and sends a light emission command corresponding to the growth state to the lighting panel 110.

[0129] The lighting panel 110 controls the light emission mode of the surface light source 111 and the point light source 112 based on the light emission command.

[0130] Preferably, the surface light source 111 emits growth-promoting light that vertically illuminates the irradiated object 200 in a manner that adapts to the photoperiod of the current growth state of the irradiated object 200, and the point light source 112 can emit pest-inhibiting light that tilts to illuminate the area near the irradiated object 200 in a rotatable manner.

[0131] Preferably, the plant and animal lighting method based on periodic emission provided in this embodiment further includes:

[0132] Based on the setting of the light source 111 on the illumination board 110, the image of the illuminated object 200 acquired by the image detection unit 120 is segmented into regions, and the segmented regions are mapped to the surface light source 111.

[0133] The geometric and positional parameters of the illuminated portion of the object 200 are confirmed based on the image.

[0134] The regions that overlap with the illuminated object 200 are selected from the image, and the combination of light sources 111 on the illumination panel 110 is determined based on the regions that overlap with the illuminated object 200.

[0135] The combination of point light sources 112 distributed along the combined edge of the surface light source 111 is determined based on the combination of surface light sources 111.

[0136] Preferably, the control unit 130 is equipped with a processor 131 and a historical database 132. The historical database 132 stores the optimal photoperiods for each growth stage of various irradiated objects 200. The processor 131 identifies the type of irradiated object 200 and its current growth stage based on an image. In response to the determination of the type of irradiated object 200 and its current growth stage, the processor 131 selects photoperiods suitable for the current growth state of the irradiated object 200 from the historical database 132.

[0137] Preferably, the processor 131 further confirms the geometric and positional parameters of the illuminated portion of the irradiated object 200 based on the image, and the processor 131 determines the combination of the surface light source 111 and the point light source 112 participating in periodic light emission on the illumination panel 110 based on the geometric and positional parameters of the illuminated portion of the irradiated object 200. Preferably, the combination enables the surface light source 111 to vertically illuminate the irradiated object 200, and the illumination area formed by the surface light source 111 is adapted to the geometric size of the irradiated object 200. Preferably, the combination enables the point light source 112 to obliquely illuminate areas of the irradiated object 200 other than the illuminated portion for pest control.

[0138] Preferably, the processor 131 filters out regions in the image that overlap with the illuminated object 200, and determines the combination of light sources 111 on the illumination panel 110 based on the regions that overlap with the illuminated object 200.

[0139] Preferably, the processor 131 is capable of determining a combination of point light sources 112 distributed along the combined edge of the surface light sources 111 based on the combination of surface light sources 111. The processor 131 adjusts the tilt angle of the point light sources 112 based on the geometric parameters of the irradiated object 200, so that the point light sources 112 illuminate the area of ​​the irradiated object 200 other than the illuminated part, in order to carry out pest control.

[0140] In this method, the surface light source can adjust different lighting cycles to adapt to the growth needs of different plant seedlings, improving the production efficiency of plant tissues. Simultaneously, by adjusting the size and shape of the light spot to suit different plants, it illuminates the area where the plant exists, avoiding light energy waste caused by the light source illuminating areas not covered by the plant, thus improving the energy utilization efficiency of the light source. Furthermore, the lighting system of this invention provides uniform illumination to the plant by vertically positioning the light source above it, preventing the plant from tilting due to phototropism, which affects its appearance. The point light source emits light during the dark period of the seedlings, illuminating the soil and inhibiting pest activity, thereby increasing the yield of high-quality seedlings.
