Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a plant lamp and its control method. Background Technology

[0002] Plant lights, also known as plant grow lights or LED plant lights, are lighting fixtures that use artificial light sources to simulate the solar spectrum, providing energy for plant photosynthesis and promoting plant growth and development.

[0003] Existing plant lights typically include various installation methods such as hanging installation, bracket installation, magnetic installation, and ground-fixed installation. In practical applications, the illumination range of a single plant light is limited. If the planting area is large, multiple plant lights need to be connected in series or parallel, or multiple plant lights can be set up individually in fixed positions to achieve the illumination needs of a large area. However, existing plant lights usually have connecting structures at both ends of the lamp body for easy connection. For example, Chinese utility model patent with authorization announcement number CN223294722U discloses a plant light with three-sided light emission. This plant light has connecting structures at both ends. When two plant lights are connected, the two connecting structures are electrically connected by inserting internal conductive parts; the two connecting structures are fixed by snapping together with the external shell. However, the above-mentioned connection structure only has a locking block or groove on one side of the outer shell, and the connection is not stable. The plant light has the following problems during long-term use: First, the outer shell usually relies on a single buckle connection, which is easily loosened by external impact. If it is loosened in the hanging installation mode, the lamp will fall. Second, the internal electrical connection relies on the structure of the plug pin and the socket itself for fixation, which is not reliable enough.

[0004] Therefore, this invention application provides a plant lamp and its control method, aiming to solve the above-mentioned problems. Summary of the Invention

Where there is no conflict, embodiments of the present invention and the various features thereof can be combined with each other, all of which are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 14 One embodiment of the present invention provides a plant lamp 1, which includes a lamp body assembly 10, a first connecting assembly 11, and a second connecting assembly 12. The first connecting assembly 11 and the second connecting assembly 12 are respectively fixedly connected to both ends of the lamp body assembly 10. The first connecting assembly 11 includes a first connector 110, which is provided with a first electrical connection portion 1100 and a first connecting portion 1110. The second connecting assembly 12 includes a second connector 120, which is correspondingly provided with a second electrical connection portion 1201 and a second connecting portion 1220. When at least two plant lamps 1 are connected, adjacent plant lamps 1 are electrically connected through the first electrical connection portion 1100 and the second electrical connection portion 1201, and are fixedly connected through the first connecting portion 1100 and the second connecting portion 1201.

[0022] In this embodiment, the two ends of the lamp body assembly 10 are respectively fixed to the first connecting assembly 11 and the second connecting assembly 12 by bolts. The first connecting assembly 11 and the second connecting assembly 12 are used to connect each other when two adjacent plant lamps 1 are connected in series. The first electrical connection part 1100 and the second electrical connection part 1201 are used to realize the electrical connection of adjacent plant lamps 1 when two adjacent plant lamps 1 are connected in series, and the first connecting part 1110 and the second connecting part 1220 are used to realize the fixed connection of the first connecting assembly 11 and the second connecting assembly 12.

[0023] In the above embodiment, by setting both the electrical connection and mechanical fixing connection of the plant lamp 1 in the first connecting component 11 and the second connecting component 12, when two adjacent plant lamps 1 are connected, the first connecting component 11 of one plant lamp 1 and the second connecting component 12 of the other plant lamp 1 are connected. In actual connection, the first electrical connection portion 1100 in the first connector 110 of the first connecting component 11 and the second electrical connection portion 1201 in the second connecting component 12 are electrically connected. At the same time, the first connecting portion 1110 in the first connector 110 of the first connecting component 11 and the second connecting portion 1220 in the second connecting component 12 are fixedly connected. The electrical connection and mechanical fixing connection of the two can be completed simultaneously by connecting the first connector 110 of one plant lamp 1 and the second connector 120 of the other plant lamp 1. Furthermore, by integrating the electrical connection and mechanical fixing connection on the first connector 110 and the second connector 120, the problems of loosening of the outer shell and unreliable internal electrical connection can be effectively solved.

[0024] Please see Figures 1 to 14 In one embodiment, the first connecting part 1110 is provided with a first slot 1111 or a block 1221, and the second connecting part 1220 is correspondingly provided with a block 1221 or a first slot 1111. The first connecting part 1110 and the second connecting part 1220 are fixedly connected by the first slot and the block.

[0025] In this embodiment, after the first slot 1111 and the card block 1221 are engaged, the first connector 110 and the second connector 120 can be fixedly connected to each other, so as to fix two adjacent plant lights 1 together through the first connecting component 11 and the second connecting component 12.

[0026] For example, both the first connecting portion 1110 and the second connecting portion 1220 are annular structures, that is, the annular structure is a three-dimensional circular structure. It is understood that one difference between the first connecting portion 1110 and the second connecting portion 1220 is that the radii of the annulus are different. The outer side of the first connecting portion 1110 is provided with a plurality of first slots 1111; the inner side of the second connecting portion 1220 is provided with a plurality of locking blocks 1221 corresponding to the first slots 1111.

[0027] In the above embodiments, specifically as follows: Figure 4 As shown, the outer surface of the first connecting part 1110 is provided with a plurality of first slots 1111. A guide block is provided at the end of each first slot 1111 away from the lamp body assembly 10. The outer surface of the guide block is a smooth bevel, used to guide the locking block 1221 to slide along the bevel towards the first slot 1111 when connected to it. When the locking block 1221 is fully inserted into the first slot 1111, it can engage with the inner surface of the guide block, forming a stable connection structure. Figure 8 and Figure 9 As shown, a locking block 1221 is provided on the inner side of the second connecting part 1220. One side of the locking block 1221 is an inclined surface, which can cooperate with the inclined surface of the guide block, so that the locking block 1221 can slide into the first locking slot 1111 more quickly.

[0028] In the above embodiment, the first slot 1111 is disposed on the outer side of the first connecting part 1110, and the card block 1221 is disposed on the inner side of the second connecting part 1220. Therefore, the inner radius of the second connecting part 1220 is greater than or equal to the outer radius of the first connecting part 1110.

[0029] In the above embodiment, the outer surface of the first connecting part 1110 is provided with a plurality of first slots 1111, which, after engaging with the plurality of corresponding slots 1221, can form a plurality of fixing points. The cooperation of the plurality of fixing points further improves the reliability of the connection between the first connecting component 11 and the second connecting component 12.

[0030] It is understandable that, in practical applications, the arrangement of the first card slot 1111 and the corresponding card block 1221 can also be such that multiple card blocks 1221 are provided on the outer side of the first connecting portion 1110, and multiple first card slots 1111 corresponding to the card blocks 1221 are provided on the inner side of the second connecting portion 1220. Alternatively, the arrangement of the first card slot 1111 and the corresponding card block 1221 can be such that multiple card blocks 1221 are provided on the inner side of the first connecting portion 1110, and multiple first card slots 1111 corresponding to the card blocks 1221 are provided on the outer side of the second connecting portion 1220. Another possible arrangement is that multiple first card slots 1111 are provided on the inner side of the first connecting portion 1110, and multiple card blocks 1221 corresponding to the first card slots 1111 are provided on the outer side of the second connecting portion 1220.

[0031] Please see Figures 1 to 14In one embodiment, the second connecting component further includes a push rod, and a push block is provided on the outer side of the second connecting part. One end of the push rod abuts against the push block. When the first connecting part and the second connecting part come into contact with each other, the push block can drive the second connecting part to rotate relative to the first connecting part under the drive of the push rod, so that the locking block can be locked after entering the first locking slot.

[0032] Furthermore, in this embodiment, the second connecting component 12 also includes a button 123. Two push blocks 1223 are disposed on the periphery of the second connecting portion 1220, with opposite ends. One end of the push rod 124 is fixedly connected to the button 123, and the other end abuts against the push block 1223. The button 123 can be used to press the push rod 124, causing the second connecting portion 1220 to rotate. When the second connecting portion 1220 rotates, the inner locking block 1221 also rotates, releasing the locking block 1221 from the first locking slot 1111. Then, the first connecting component 11 and the second connecting component 12 are separated by pulling the adjacent plant light 1.

[0033] Please see Figures 1 to 14 In one embodiment, the second connecting component 12 further includes an elastic element, and the second electrical connection 1201 abuts against the second connecting part 1220 through the elastic element; the push block 1223 can drive the second connecting part 1220 to compress the elastic element under the drive of the push rod 124, and when the elastic element in the compressed state returns to the extended state, the second connecting part 1220 can drive the push block 1223 and the push rod 124 to reset under the drive of the elastic element.

[0034] For example, the second electrical connection portion 1201 is disposed within the ring of the second connecting portion 1220; an annular flange 1207 is provided at one end of the second electrical connection portion 1201 near the lamp body assembly 10, and a mounting groove 1206 and a limiting groove 1208 are provided on the periphery of the annular flange 1207; a mounting block 1222 corresponding to the mounting groove 1206 and a limiting block 1224 corresponding to the limiting groove 1208 are provided on the inner side of the second connecting portion 1220; a plurality of notches 1209 are provided on the flange 1207 respectively corresponding to the mounting block 1222 and the limiting block 1224; the mounting block 1222 is installed in the mounting groove 1206, and the limiting block 1224 is installed in the limiting groove 1208. The elastic member is installed in the corresponding mounting groove 1206, one end of the elastic member is connected to the mounting groove 1206, and the other end abuts against the mounting block 1222.

[0035] In this embodiment, the second connecting portion 1220 can be sleeved around the flange 1207. The elastic element within the mounting groove 1206 allows the second connecting portion 1220 to rotate and compress the elastic element before resetting. Specifically, the elastic element can be a spring. The notch 1209 ensures that when the second connecting portion 1220 is sleeved with the flange 1207, the limiting block 1224 and the mounting block 1222 can enter the mounting groove 1206 and the limiting groove 1208. Figure 10 As shown, the two side walls of one end of the mounting groove 1206 are provided with protruding structures for engaging with the spring. Simultaneously, the mounting block 1222 compresses the elastic element; when the button 123 is released, the elastic element returns to its original state, pushing the mounting block 1222 to rotate, thereby resetting the second connecting part 1220.

[0036] Please see Figures 1 to 14 In one embodiment, the first electrical connection portion 1100 is disposed within the ring of the first connection portion 1110; the first electrical connection portion 1100 includes a first socket 1101 and a plurality of first plugs 1102, the first socket 1101 separating the plurality of first plugs 1102, and the first socket 1101 being provided with a plurality of first socket holes 1103; the second electrical connection portion 1201 is provided with a slot 1202 corresponding to the first socket 1101, a second plug 1205 corresponding to the first socket hole 1103, and a second socket 1203 corresponding to the first plug 1102, the second socket 1203 being provided with a second socket hole 1204 corresponding to the first plug 1102.

[0037] In this embodiment, when the first electrical connection 1100 and the second electrical connection 1201 are connected, the first socket 1101 and the slot 1202 are physically fitted together. Initial positioning is achieved through shape matching, ensuring precise alignment of the first ferrule 1102 and the second socket 1204, and the second ferrule 1205 with the first socket 1103. This avoids ferrule bending or poor contact caused by existing misalignment, ensuring the stability of the electrical connection. For an example, please refer to [link to example]. Figure 4 and Figure 10The first socket 1101 includes a head and a tail, which are located at opposite ends. The top of the head is an outwardly protruding arc surface, and the tail is an inwardly concave arc surface. The two sides between the head and tail are also inwardly concave arc surfaces, forming two isolation arms at the tail. Multiple first plugs 1102 are arranged opposite to the corresponding concave arc surfaces, isolating the multiple first plugs 1102 to prevent short circuits and further improve the stability of the electrical connection. The outer contour of the slot 1202 is the same as the outer contour of the first socket 1101, ensuring that they can fit together. The outer contour of the slot 1202 and the outer contour of the second connecting part 1220 form a second socket 1203. The space formed between the second socket 1203 and the inner edge contour of the annular structure in the first connecting part 1110 can fit together to ensure the stability of the connection. The fit between the space formed between the second socket 1203 and the inner edge contour of the annular structure in the first connecting part 1110 allows the second ferrule 1205 and the first socket 1103 to be inserted. This arrangement can form a main circuit when the first ferrule 1102 is inserted into the second socket 1204, and form an auxiliary conductive path when the second ferrule 1205 is inserted into the first socket 1103, which can avoid short circuits.

[0038] In the above embodiments, the electrical connection is completely enclosed by the first connecting portion 1110 and the second connecting portion 1220 of the mechanical connection, which can prevent dust, moisture, etc. from directly intruding into the conductive components. Furthermore, the ferrule and socket of the electrical connection only bear the axial insertion and extraction force, while the radial tension is borne by the outer first slot 1111 and the locking block 1221, which can avoid the deformation of the electrical contact points caused by gravity or vibration when the lamp body is suspended, and the overall structure is more stable.

[0039] Please see Figures 1 to 14 In one embodiment, the first connecting component 11 includes a first housing 111, and the second connecting component 12 includes a second housing 121; both the first connector 110 and the second connector 120 are provided with an abutment block 1120 at one end near the lamp body component 10; both the first housing 111 and the second housing 121 are provided with a mounting through hole 11113, and a stop block is provided at the bottom of the mounting through hole 11113; the first connecting component 11 is installed in the mounting hole of the first housing 111 and fixed by the abutment block 1120; and the second connecting component 12 is installed in the mounting hole of the second housing 121 and fixed by the abutment block 1120.

[0040] In this embodiment, the abutment block 1120 is provided with a threaded hole, and the first connector 110 and the second connector 120 are provided with threads on their peripheral sides at the ends near the lamp body assembly 10. After the first connector 110 and the second connector 120 are respectively installed in the mounting through holes 11113 of the first housing 111 and the mounting through holes 11113 of the second housing 121, they are fixedly connected through the threaded holes in their respective abutment blocks 1120 and the threads of the first connector 110 and the second connector 120. After connection, the stop block of the first housing 111 is clamped and fixed between the abutment block 1120 and the protrusion of the first connector 110, thereby realizing the installation and fixation of the first connector 110 and the first housing 111.

[0054] To provide a more thorough and comprehensive understanding of the contents disclosed in this invention, this application also provides a control method applied to a large-area zoned planting environment, where each plant zone corresponds to a different plant species, and each zone is equipped with a plurality of plant lights 1 as described in any of the above claims. The control method is used to control the light intensity and color temperature adjustment of the plurality of plant lights 1, characterized in that the control method includes: Synchronize and control the system time according to the user's time zone; Based on the growth stages of each plant zone, obtain the corresponding periodic table for that stage. Obtain the target light intensity and target color temperature preset in the periodic table of the current time period for each plant zone; The light intensity detected by the ambient light sensor within the plant zone is obtained, and the corrected target light intensity is calculated to compensate for changes in ambient light. Determine the ratio between high color temperature LED 1010 and low color temperature LED 1011 based on the target color temperature; Based on the illumination area and partition location corresponding to each plant light 1, establish the coverage relationship between plant light 1 and partition; Calculate the target output brightness of each plant light 1 based on the target light intensity and coverage relationship of each zone; When the output power of some plant lights 1 reaches the upper limit, light compensation is allocated between adjacent plant lights 1 according to the priority of the zone and the priority of the growth stage. Based on the target output brightness and the ratio of high and low color temperatures corresponding to the target color temperature of each zone, calculate the output ratio of the high color temperature channel and the low color temperature channel of each plant light 1. When some plant lights 1 illuminate multiple zones simultaneously, the output ratio of the high color temperature channel and the low color temperature channel after weighted average is calculated based on the coverage of each zone and the light weight. Based on the target output ratio of the high color temperature and low color temperature channels of each plant light 1, a first control signal and a second control signal are generated. The brightness and color temperature of the corresponding plant lamp 1 are controlled by modulating the pulse signal or constant current drive signal according to the first control signal and the second control signal.

[0055] In this embodiment, a control method is provided for use in environments where different plants are planted in large-area zones, with several plant lights 1 arranged in each zone. By coordinating the control of the light intensity and color temperature of each plant light 1, the system can meet the spectral and light requirements of different plants at different growth stages, achieving energy saving and efficient growth regulation of the planted plants.

[0056] In this embodiment, system time refers to the unified time base used for calculation and scheduling within the control device. By synchronizing the system time according to the user's time zone, it can be ensured that the lighting control is consistent with the local circadian rhythm. For example, the control system operating in the East Eighth Time Zone calibrates the system time to local time via network protocol or GPS timing module to avoid misalignment of light cycles due to time zone differences and improve the consistency of plant growth rhythm. The stage period table is a preset growth stage database that defines the light parameters for each plant at different stages, such as budding, vegetative growth, flowering, and fruiting. The system reads the corresponding period table based on the current growth stage of the plants planted in each plant zone and extracts parameters such as target light intensity and color temperature. For example, vegetable plants require light with a higher proportion of blue light and a higher color temperature during the vegetative growth stage, while requiring warmer, lower color temperature light during the flowering and fruiting stage, allowing for light adjustment based on the growth stage.

[0057] In the above embodiments, an ambient light sensor is used to detect the intensity of natural light or auxiliary lighting. The system can correct the target light intensity in the original periodic table based on the ambient light intensity measured by the sensor. For example, if the natural light is enhanced, the output of plant lamp 1 is reduced to achieve energy-saving supplemental lighting; if the ambient light is weak, supplemental lighting is increased. High color temperature LED 1010 typically emits bluish-white light, while low color temperature LED 1011 emits reddish-warm light. Based on the target color temperature, the output ratio of high and low color temperature channels is determined by looking up a table or interpolation calculation, enabling continuously adjustable spectral control to meet the photosynthetic needs of different plants.

[0058] In the above embodiments, the target output brightness refers to the light intensity or power percentage that each plant lamp 1 should output. Based on the target light intensity of each zone and the contribution of each lamp in the coverage matrix to the zone, a matrix solving or weighted average algorithm is used to allocate the output brightness of each plant lamp 1, thereby achieving multi-lamp-to-multi-zone light distribution and preventing some areas from being too bright or too dark. When some plant lamps 1 have reached their output power limit and cannot be brightened further, the system automatically allocates supplementary lighting tasks among adjacent lamps according to zone priority (e.g., priority for primary growth stages, such as priority for flowering stages) to maintain overall illuminance balance.

[0059] In the above embodiment, the high color temperature and low color temperature channel outputs of each plant lamp 1 are calculated based on the ratio between the target output brightness and the target color temperature. If the plant lamp 1 illuminates multiple zones at the same time, such as plant lamp 1 being set between adjacent plants in two adjacent zones, a weighted average algorithm is used to determine the output ratio based on the coverage ratio and weight.

[0060] In the above embodiment, the first control signal corresponds to the high color temperature channel, and the second control signal corresponds to the low color temperature channel. They are modulated into a pulse width modulation signal or a constant current drive signal to control the current or duty cycle of the high color temperature lamp and low color temperature lamp drive power supply in the plant lamp 1, thereby realizing the control of the brightness and spectrum of the plant lamp 1.

[0061] In one embodiment, the control method further includes: When a new time period is detected to begin, the target illumination intensity and target color temperature for that time period are acquired. Adjust the irradiation ratio of high color temperature and low color temperature LED beads 1011 according to the target light intensity and target color temperature; When a user receives a color temperature adjustment command for a specific partition or the entire system, the system calculates the high and low color temperature ratio based on the command and generates a control signal. The adjustment instruction includes the adjusted target color temperature; The brightness and color temperature of the corresponding plant light 1 are controlled according to the control signal.

[0062] In this embodiment, when the system detects the start of a new time period, switching from a morning cycle to an afternoon cycle, it automatically acquires the target light intensity and target color temperature corresponding to that time period, and adjusts the ratio of high and low color temperature LED beads 1011 according to the difference. Furthermore, when the user detects an anomaly or requires manual adjustment, the user can input a color temperature adjustment command through the control terminal. The system recalculates the high and low color temperature output ratio based on the command and generates a new control signal, enabling automatic dynamic adjustment according to the time cycle. It also supports real-time spectral fine-tuning under user intervention, allowing the system to flexibly switch between automatic control and manual intervention.

[0063] In one embodiment, the step of allocating light compensation among adjacent plant lights 1 according to zone priority and growth stage priority when the output power of some plant lights 1 reaches the upper limit includes: The light intensity of each zone covered by the plant light 1 is obtained, and it is determined whether the light intensity is less than the corresponding target light intensity. If so, then based on the coverage relationship between plant light 1 and the partition, obtain plant light 1 that is adjacent to the partition with insufficient light intensity and has not reached the power limit, and use it as a compensation light; Obtain partition priority and growth stage priority data, and determine the compensation order based on the priority order; The compensation output of each compensation lamp is calculated based on its remaining output power and its coverage of the insufficiently lit area. The brightness is output according to the compensation output amount; Based on the compensated output brightness, control signals are generated for high color temperature and low color temperature channels, and the illuminance and color temperature of the compensation lamp are adjusted according to the control signals.

[0064] In this embodiment, the real-time light intensity of each zone is read and compared with the target light intensity to identify areas with insufficient light. Based on the coverage matrix, plant lights (1) adjacent to the insufficient-light zones and not yet reaching their power limits are selected as compensation lights. The system reads the zone priority and growth stage priority, prioritizing compensation for key crops or key growth stages. Based on the remaining power of the compensation lights and the coverage level, the required increase in output for each compensation light is calculated, which can be achieved through a proportional allocation algorithm. The calculation results are converted into target brightness values, and corresponding high and low color temperature channel control signals are generated to drive the compensation light output. Even if some lights have limited power, the system can still maintain overall light balance through supplemental lighting from neighboring lights, improving the robustness of control.

[0065] In one embodiment, the step of calculating the weighted average output ratio of the high color temperature channel and the low color temperature channel based on the coverage and light weight of each zone when some plant lights 1 simultaneously illuminate multiple zones includes: Obtain the illumination range of the plant light 1 and the plant zones it covers; Obtain the target color temperature of each plant partition for the current time period and the corresponding target ratio of high color temperature channel and low color temperature channel; The light weight of each plant zone is determined based on the target light intensity and growth stage priority of each plant zone; Based on the coverage ratio of the plant lamp 1 in each zone and the light weight, calculate the weighting factor for each zone; Based on the target values ​​for the high and low color temperature ratios of each zone and the weighting factor, the weighted average output ratio of the high color temperature channel and the low color temperature channel of the plant lamp 1 is calculated.

[0066] In this embodiment, the illumination range refers to the area covered by the light beam of the plant lamp 1 in space, which is determined by the beam angle, installation height, installation angle, and reflection conditions. The coverage zone refers to all plant planting zones within the illumination range that intersect with the zone coordinate area. The system first calculates the spatial boundary of the illumination cone based on the installation coordinates and beam angle of the plant lamp 1, then performs geometric intersection calculations between the illumination area and the plant zone layout to obtain the set of zones covered by the lamp, and records the proportion C of the illuminated area of ​​each zone. i This refers to the degree of coverage. For example, if the illumination range of plant light 1A overlaps with zone one by 40% and with zone two by 60%, then C1=0.4 and C2=0.6.

[0067] In the above embodiments, the illumination weight is used to characterize the importance of a certain partition in the overall lighting calculation, including the target illumination intensity and growth stage priority. The illumination weight can be obtained by multiplying the partition's target illumination intensity and growth stage priority weight coefficients. For example, the weight coefficient for the seedling stage is 0.8, the weight coefficient for the flowering stage is 1.0, and the weight coefficient for the fruiting stage is 1.2. Through the above processing, partitions in critical growth stages or with high light requirements can obtain higher control weights when subjected to mixed illumination from multiple regions.

[0068] In the above embodiments, the weighting factor for each partition is determined by multiplying the coverage ratio and the illumination weight, which can comprehensively reflect the effective influence of plant light 1 on different partitions. The larger the value, the higher the illumination contribution of plant light 1 to that partition. For example, if a plant light 1 has a coverage rate of 40% and a weight of 0.8 for partition one, and a coverage rate of 60% and a weight of 1.2 for partition two, then plant light 1 has a greater illumination contribution to partition two.

[0069] In the above embodiments, after determining the illumination weight and coverage of each zone, the overall spectral proportion that the plant lamp 1 should output can be calculated based on the target ratio of high color temperature to low color temperature in each zone. For example, the system first calculates a weighted average based on the weighting factor of each zone and the target high color temperature ratio. This average represents the overall high color temperature channel ratio when the lamp simultaneously illuminates multiple zones, while the low color temperature channel ratio can be obtained from their complementary relationship, i.e., the low color temperature ratio equals one minus the high color temperature ratio. In other words, the system comprehensively considers the importance of each zone and its spectral requirements, weighting and superimposing these factors to obtain the high and low color temperature output ratio of the plant lamp 1. In actual calculations, if the importance of a certain zone, such as its illumination weight or coverage ratio, is high, then the color temperature parameter of that zone will have a greater impact on the overall result. For example, suppose a plant lamp 1 simultaneously illuminates two zones: the target high color temperature ratio for zone one is 70%, with a corresponding weighting factor of 0.32; the target high color temperature ratio for zone two is 40%, with a corresponding weighting factor of 0.72. During the comprehensive calculation, the system multiplies the high color temperature ratios of Zone 1 and Zone 2 by their respective weighting factors, then sums them to obtain the total weighted high color temperature ratio across all zones. This total is then divided by the sum of all weighting factors to obtain the high color temperature output ratio of the luminaire. Based on this calculation, the overall high color temperature output ratio of the luminaire is approximately 49%, and the corresponding low color temperature output ratio is approximately 51%. This means that the luminaire should output approximately 49% high color temperature light (bluish-white light) and approximately 51% low color temperature light (reddish-warm light) during the current time period to simultaneously meet the spectral requirements of both zones. Through this weighting method, the system can achieve a balance and coordination of spectral output in complex environments where multiple zones are simultaneously illuminated, ensuring that different plant species receive illumination close to their optimal color temperature conditions, thereby improving overall light energy utilization and plant growth uniformity.

[0070] In one embodiment, the step of establishing the coverage relationship between the plant light 1 and the partition based on the illumination area and partition location corresponding to each plant light 1 includes: Obtain the spatial coordinate system, illumination angle, and beam angle information for each plant light 1, and establish an initial geometric model; Based on the luminous intensity distribution curves and partition locations of the lamps, the theoretical coverage matrix is ​​calculated and then normalized. The individual plant lights 1 are lit sequentially, the measured light intensity values ​​of the light sensors in each zone are read, and the actual coverage matrix is ​​derived from the measured light intensity values. The theoretical coverage matrix and the actual coverage matrix are weighted and fused to obtain the corrected coverage matrix, wherein the weighting coefficients are determined based on the reliability of the sensor data. During long-term operation, the measured light intensity data of each partition is periodically acquired, the deviation between the target light intensity and the measured light intensity is calculated, and the coverage matrix is ​​updated according to the least squares method to form an iterative matrix. During the iterative matrix update process, when the change in light intensity exceeds a preset threshold, the matrix data of the previous version is restored.

[0071] In this embodiment, during the system deployment phase, the spatial coordinates of each plant light 1 are first determined, including horizontal coordinates, installation height, installation angle, beam angle, and other parameters. Based on this data, a three-dimensional geometric model is established in the control system, matching the illumination direction of each light fixture with the zoning layout to obtain the theoretical illumination range of each light fixture on the planting plane. In this process, the beam angle is defined as the angle formed when the light intensity on both sides of the light fixture's main optical axis attenuates to 50% of its maximum value, determining the main illumination coverage area of ​​the light fixture. Through this modeling step, a preliminary spatial correspondence can be obtained, providing a theoretical basis for subsequent illumination allocation. For example, when a light is installed at coordinates 2m, 3m, and height 2.5m with a beam angle of 60°, its illumination cone forms a circular coverage area with a diameter of approximately 3 meters on the plane, covering multiple plant zones.

[0072] In the above embodiments, after obtaining the geometric model, the system calculates the theoretical illuminance contribution of each lamp in each zone based on the illuminance distribution curve of each lamp, for example, the illuminance distribution obtained through IES photometric files or experimental data. The theoretical illuminance contribution can be understood as the proportion of illuminance generated by the lamp at the center point or average position of the zone. The system organizes the theoretical illuminance relationships between all lamps and all zones into a two-dimensional matrix, called the theoretical coverage matrix. To eliminate the influence of differences in the power or luminous flux of different lamps, the system normalizes the matrix to ensure that the total illuminance distribution of each lamp remains consistent. This theoretical coverage matrix describes the light influence relationship between each lamp and the zone under ideal conditions. Since the light distribution in the actual planting environment is affected by factors such as reflection, shading, and lamp angle deviation, there is an error between the theoretical model and the actual lighting conditions. To correct this error, the system sequentially lights up a single plant lamp 1 while keeping the other lamps off, and uses light sensors distributed in each zone to collect measured illuminance values. Based on the proportion of illuminance values ​​detected by the sensors in each zone, the system can deduce the actual illuminance contribution of each lamp to each zone, thus forming the actual coverage matrix. This matrix more closely approximates the actual light distribution, reflecting the relationship between the actual installation of the luminaires and the illumination under environmental conditions.

[0073] In the above embodiments, to balance the stability of the theoretical model with the authenticity of the measured data, the system performs a weighted fusion of the theoretical coverage matrix and the actual coverage matrix. During fusion, the weighting coefficients are set according to the reliability of the sensor data. For example, when sensor data fluctuations are small and ambient light interference is weak, the system can increase the weight of the measured matrix; conversely, it increases the weight of the theoretical matrix. The weighted fused matrix is ​​called the corrected coverage matrix, which maintains the continuity of the theoretical model while fully considering the real feedback from the environment, and can more accurately reflect the light distribution ratio of each luminaire in each zone. During long-term system operation, environmental factors such as changes in plant growth height, changes in light reflection conditions, and luminaire aging can cause a slow shift in the light distribution.

[0074] In the above embodiments, to ensure the long-term accuracy of the coverage relationship, the system employs a periodic self-learning mechanism: during operational breaks or nighttime cycles, the system periodically collects measured illuminance data from each zone, compares it with the target illuminance value, and calculates the deviation. Based on these deviations, the system updates the coverage matrix using the least squares method or a proportional correction algorithm, enabling the new matrix to better fit the current actual illuminance distribution. In this way, the coverage matrix continuously optimizes as the system operates, forming an iterative matrix, achieving continuous self-learning and adaptive correction. Simultaneously, to prevent abnormal data caused by individual sensor malfunctions or external light source interference from affecting matrix stability, the system detects the update magnitude each time the matrix is ​​updated.

[0075] When an update causes any element in the matrix to change by more than a preset threshold, such as ±15%, the system will automatically abandon the update and restore the matrix data of the previous version.

[0076] It should be noted that after a long period of operation, if the system detects a significant change in plant height, such as exceeding the original set height by 20%, or if the lights are replaced or their positions are adjusted, the system will automatically enter calibration mode.

[0077] In this mode, the system sequentially illuminates each plant lamp 1 and re-collects measured illuminance, then recalculates a new actual coverage matrix. Subsequently, the new measured matrix is ​​merged with the previously corrected matrix to establish a new base matrix model, thereby redefining the coverage relationship of each lamp. The corrected coverage matrix is ​​directly used as the input parameter for multi-lamp illuminance intensity allocation. When the system calculates the output power of each lamp based on the target illuminance of each zone, the coverage matrix provides the weight ratio of each lamp to each zone. Through matrix solving, the system can accurately allocate the output of each lamp, ensuring that the target illuminance of different zones is simultaneously satisfied.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.

The ratio of high color temperature LED beads to low color temperature LED beads is determined based on the target color temperature; Establish the coverage relationship between the plant lights and the zones based on the illumination area and zone location corresponding to each plant light; Calculate the target output brightness of each plant light based on the target light intensity and coverage relationship of each zone; Based on the target output brightness and the ratio of high and low color temperatures corresponding to the target color temperature of each zone, calculate the output ratio of the high color temperature channel and the low color temperature channel of each plant light. Based on the target output ratio of the high color temperature and low color temperature channels of each plant light, a first control signal and a second control signal are generated. The brightness and color temperature of the corresponding plant light are controlled by modulating the pulse signal or constant current drive signal according to the first control signal and the second control signal.
