AI Technical Summary
Existing LED plant growth promoters cannot adjust the light intensity according to the different growth conditions of different plant areas, resulting in plants in different areas within the same range not receiving adequate supplemental lighting.

Abstract
Description
Technical Field
[0001] This disclosure relates to the field of plant cultivation, and more specifically to a plant growth-promoting supplemental lighting module and a cultivation shed. Background Technology
[0002] In the process of plant cultivation, LED plant growth promoters are usually installed in plant cultivation sheds to provide supplemental light and promote plant growth.
[0003] Chinese patent document CN219437652U discloses an LED plant growth promoting light. Through the cooperation of a connector block, spring plate, connector slot, and locking block, the LED light panel can be disassembled and assembled, facilitating quick repair or replacement of the grow light, improving repair or replacement efficiency, ensuring normal use of the grow light, and achieving effective supplemental lighting for plants.
[0004] Chinese patent document CN216853161U discloses an LED plant growth promoting light, which is convenient for use in green plant cultivation greenhouses. It can effectively provide supplemental lighting to individual plants to promote growth, and can be easily moved and repositioned within the greenhouse, with its height adjustable as needed. It also has the advantages of easy assembly and storage.
[0005] The LED plant growth promoters described in the aforementioned Chinese patent documents can only emit light of a specific intensity, making them relatively uniform and not freely adjustable. Furthermore, for plants within the illumination range of the LED plant growth promoter, the required light intensity may differ depending on the actual growth conditions of the plants in different areas within that range. Using the same LED plant growth promoter cannot accommodate the varying intensity requirements of supplemental lighting for plants in different areas within the same range (in other words, it cannot ensure that the supplemental lighting for plants in different areas within the same range reaches an appropriate intensity for each individual). Utility Model Content
[0006] In view of the problems existing in the background art, one object of this disclosure is to provide a plant growth promotion supplementary lighting module and a cultivation shed, which enables plants in different areas within the same range to achieve the required appropriate lighting intensity.
[0007] Therefore, a plant growth-promoting supplemental lighting module is provided, comprising an LED plant growth-promoting lamp, an electrochromic module, multiple zone controllers, and multiple optical sensors. The LED plant growth-promoting lamp is positioned above multiple plants requiring supplemental lighting. The electrochromic module is positioned vertically between the LED plant growth-promoting lamp and the plants requiring supplemental lighting. The electrochromic module includes multiple electrochromic units, each capable of electrochromic changes, resulting in adjustable transmittance. The vertical projection of each electrochromic unit covers the corresponding plant requiring supplemental lighting. Multiple zone controllers are respectively positioned on the multiple electrochromic units, and each zone controller is communicatively connected to its corresponding electrochromic unit to enable the corresponding electrochromic unit to perform electrochromic changes. Multiple optical sensors are positioned below the electrochromic module along the vertical direction. Each optical sensor is positioned near the plant to be illuminated within the area projected by the corresponding electrochromic unit in the vertical direction. The sensor determines the range of direct LED light intensity of the plant within the area and communicates the determined range of direct LED light intensity to the corresponding partition controller. This enables the partition controller to control the corresponding electrochromic unit to perform electrochromic changes in a manner where the larger the determined range of direct LED light intensity, the deeper the electrochromic change and the lower the transmittance exhibited after electrochromic changes.
[0008] A cultivation shed includes a shed and the aforementioned plant growth-promoting supplemental lighting module, which is installed inside the shed.
[0009] The beneficial effects of this disclosure are as follows: In the plant growth-promoting supplemental lighting module and cultivation shed according to this disclosure, an electrochromic module, comprising multiple electrochromic units, is used to separate the supplemental lighting of the multiple plants according to the correspondence between the LED plant growth-promoting lamp and the multiple plants to be supplemented with light. In other words, the area where the multiple plants to be supplemented with light are located is divided into different regions. Although the light emitted by the same LED plant growth-promoting lamp to promote the growth of multiple plants to be supplemented with light is a single light, through communication between each optical sensor and the zone controller, and the color-changing control of the corresponding electrochromic units by the zone controller, the light emitted by the LED plant growth-promoting lamp is adjusted through the electrochromic units to correspondingly reduce its intensity, thereby ensuring that the light illuminating the plants is at the appropriate intensity required by the plants. In short, even when the light emitted by the LED plant growth-promoting lamp is a single light, it is possible to ensure that the supplemental lighting of plants in different areas within the same range reaches an appropriate intensity, that is, it can adapt to the different intensity requirements of supplemental lighting for plants in different areas within the same range. This makes plant cultivation easier, prevents plants from withering due to lack of light, and also avoids excessive light from inhibiting plant growth, thus promoting healthier plant growth.

[0029] The accompanying drawings illustrate embodiments of this disclosure, and it will be understood that the disclosed embodiments are merely examples of this disclosure, which can be implemented in various forms. Therefore, the specific details disclosed herein should not be construed as limiting, but are intended only as the basis for the claims and as an illustrative basis to teach those skilled in the art how to implement this disclosure in various ways.
[0030] [Plant Growth Promotion and Supplemental Lighting Module]
[0031] Reference Figures 1 to 7 The plant growth promotion supplementary lighting module 100 disclosed herein includes an LED plant growth promotion lamp 1, an electrochromic module 2, multiple zone controllers C1, C2, ..., Cn, and multiple optical sensors S1, S2, ..., Sn.
[0032] LED plant growth promoter 1 is used to position above multiple plants P1, P2, ..., Pm, m≥n that need supplemental lighting. Electrochromic module 2 is positioned along the vertical direction D between LED plant growth promoter 1 and multiple plants P1, P2, ..., Pm that need supplemental lighting. Electrochromic module 2 includes multiple electrochromic units EC1, EC2, ..., ECn. Each electrochromic unit ECi, i = 1, 2, ..., n can achieve electrochromic changes, thus making the transmittance exhibited after the electrochromic unit ECi changes color adjustable. The projection of each electrochromic unit ECi along the vertical direction D covers the corresponding supplemental plant Pj, j = 1, 2, ..., m. Multiple partition controllers C1, C2, ..., Cn are respectively set on multiple electrochromic units EC1, EC2, ..., ECn. Each partition controller Ci, i = 1, 2, ..., n is communicatively connected to the corresponding electrochromic unit ECi so that the corresponding electrochromic unit ECi performs electrochromic changes. Multiple optical sensors S1, S2, ..., Sn are positioned below the electrochromic module 2 along the vertical direction D. Each optical sensor Si, i = 1, 2, ..., n is positioned near the plant Pj to be supplemented with light within the area projected by the corresponding electrochromic unit ECi in the vertical direction D. The sensor determines the range of direct LED illumination intensity lxi, i = 1, 2, ..., n of the plant Pj in that area. The determined range of direct LED illumination intensity lxi is communicated back to the partition controller Ci corresponding to the electrochromic unit ECi. This causes the partition controller Ci to control the corresponding electrochromic unit ECi to perform electrochromic changes in a manner where the larger the determined range of direct LED illumination intensity lxi, the deeper the electrochromic change and the lower the transmittance exhibited after electrochromic changes.
[0033] In the plant growth promotion supplemental lighting module 100 according to this disclosure, an electrochromic module 2, comprising multiple electrochromic units EC1, EC2, ..., ECn, is used to divide the supplemental lighting of the multiple plants P1, P2, ..., Pm between the LED plant growth promotion lamp 1 and the multiple plants to be supplemented with light in the vertical direction D. In other words, the area where the multiple plants P1, P2, ..., Pm are located is divided into different zones. In the same area, although the light emitted by the same LED plant growth promoter 1 to promote the growth of multiple plants P1, P2, ..., Pm is a single light, due to the communication between each optical sensor Si and the zone controller Ci, and the color-changing control of the corresponding electrochromic unit ECi by the zone controller Ci, the corresponding electrochromic unit ECi will adjust its transmittance to adapt to the LED direct light intensity range lxi determined by the optical sensor Si. This transmittance adjustment makes the light intensity from the LED plant growth promoter 1 to the corresponding plant Pj to be supplemented with light relative to the LED light source via the corresponding electrochromic unit ECi. The direct light intensity range lxi (i.e., the light emitted by the LED plant growth promoter 1 directly to the corresponding plant Pj without the electrochromic unit ECi) changes. This change occurs in a manner that the larger the LED direct light intensity range lxi is, the deeper the electrochromic effect of the corresponding electrochromic unit ECi, and the lower the transmittance exhibited after electrochromic transformation. Thus, when the LED plant growth promoter 1 emits light directly to the corresponding plant Pj with a large LED direct light intensity range lxi (i.e., strong light intensity), the corresponding electrochromic unit ECi exhibits low transmittance after electrochromic transformation, thereby reducing the transmittance of the plant Pj. When the light emitted by lamp 1 reaches the corresponding plant Pj via the corresponding electrochromic unit ECi, the light intensity weakens. When the direct light intensity range lxi of the LED plant growth promoting lamp 1 reaching the corresponding plant Pj is small (i.e., the light intensity is not very strong), the transmittance exhibited by the corresponding electrochromic unit ECi after electrochromic changes is not very low. Therefore, when the light emitted by LED plant growth promoting lamp 1 reaches the corresponding plant Pj via the corresponding electrochromic unit ECi, the light intensity is not too weak. This ensures that the corresponding plants Pj in different areas within the same range are under their respective suitable light intensities.In other words, although the same LED plant growth promoter 1 emits a single light to promote the growth of multiple plants P1, P2, ..., Pm requiring supplemental lighting, the light emitted by the LED plant growth promoter 1 is adjusted through the electrochromic unit ECi by the communication between each optical sensor Si and the zone controller Ci, and the zone controller Ci controls the color change of the corresponding electrochromic unit ECi. This ensures that the light illuminating plant Pj is at the appropriate intensity required by plant Pj. In short, even when the LED plant growth promoter 1 emits a single light, it can ensure that the supplemental lighting of plants Pj in different areas within the same range reaches an appropriate intensity, thus adapting to the different intensity requirements of plants in different areas within the same range. This facilitates plant cultivation, prevents plants from withering due to lack of light, and avoids excessive light from inhibiting plant growth, thus promoting healthier plant growth.
[0034] Reference Figures 1 to 7 In one example, each optical sensor Si is used to determine the range of direct LED illumination intensity lxi of the plant Pj to be illuminated in the region based on the distance di,i = 1,2,...,n between the plant Pj to be illuminated and the LED plant growth promoter 1 in the vertical direction D.
[0035] Specifically, refer to Figure 1 The given example, in Figure 1 In the diagram, four electrochromic units ECi, zone controller Ci, optical sensor Si, and plants Pj to be illuminated are shown, i.e., n=4 and m=4. Each electrochromic unit ECi is shown without exhibiting electrochromic properties. The distances d1, d2, d3, and d4 between the four plants P1, P2, P3, and P4 and the LED plant growth promoter 1 are different (i.e., d1≠d2≠d3≠d4). The areas occupied by the four plants P1, P2, P3, and P4 correspond to the four electrochromic units EC1, EC2, EC3, and EC4, and are divided into four regions, as shown below. Figure 1The lower dashed rectangle is shown. The distance d1 between the plant P1 to be supplemented with light and the LED plant growth promoter 1 is the farthest, and the range lx1 of direct light intensity to the LED determined by the optical sensor S1 is the smallest. After communication between the optical sensor S1 and the partition controller C1, the partition controller C1 controls the color change of the electrochromic unit EC1 so that the transmittance exhibited by the electrochromic unit EC1 after electrochromic change is the largest among the four electrochromic units EC1, EC2, EC3, and EC4. In this way, the light emitted by the LED plant growth promoter 1 is adjusted to the least weak level when passing through the electrochromic unit EC1. The distance d2 between the plant P2 to be supplemented with light and the LED plant growth promoter 1 is the second largest. The range of direct light intensity for the LED determined by the optical sensor S2 is the second smallest. After communication between the optical sensor S2 and the partition controller C2, the partition controller C2 controls the color change of the electrochromic unit EC2 so that the transmittance exhibited by the electrochromic unit EC2 after electrochromic change is the second largest among the four electrochromic units EC1, EC2, EC3, and EC4. In this way, the light emitted by the LED plant growth promoter 1 is adjusted to the second largest degree of weakness when it passes through the electrochromic unit EC2. The distance d4 between the plant P4 to be supplemented with light and the LED plant growth promoter 1 is the closest. The optical sensor S4 determines the maximum range of direct light intensity lx4 for the LED. After communication between the optical sensor S4 and the partition controller C4, the partition controller C4 controls the color change of the electrochromic unit EC4 so that the transmittance exhibited by the electrochromic unit EC4 after electrochromic change is the smallest among the four electrochromic units EC1, EC2, EC3, and EC4. In this way, the light emitted by the LED plant growth promoter 1 is adjusted to the weakest level when it passes through the electrochromic unit EC4. The distance d3 between the plant P3 to be supplemented with light and the LED plant growth promoter 1 is the second closest. The range of direct light intensity lx3 determined by the optical sensor S3 for the LED is the second largest. After communication between the optical sensor S3 and the partition controller C3, the partition controller C3 controls the color change of the electrochromic unit EC3 so that the transmittance exhibited by the electrochromic unit EC3 after electrochromic change is the second smallest among the four electrochromic units EC1, EC2, EC3, and EC4. Thus, the light emitted by the LED plant growth promoter 1 is adjusted to the second weakest level when passing through the electrochromic unit EC4. The electrochromic behavior of the four electrochromic units EC1, EC2, EC3, and EC4 is as follows. Figure 2As shown. In other words, the closer the plant Pj to be supplemented with light is to the LED plant growth promoter 1, the smaller the distance di between the plant Pj and the LED plant growth promoter 1 in the vertical direction D, the larger the direct light intensity range of the LED plant growth promoter 1 (the stronger the light), the deeper the electrochromic unit ECi, and the lower the transmittance after electrochromic transformation. The light emitted by the LED plant growth promoter 1 is adjusted to a weaker degree when passing through the electrochromic unit ECi, so that the light reaching the plant Pj is at a suitable light intensity.
[0036] Similarly, in Figure 3 In the example, the four plants P1, P2, P3, and P4 to be supplemented with light are all at the same distances d1, d2, d3, and d4 from the LED plant growth promoter 1 (i.e., d1 = d2 = d3 = d4), and the control... Figure 1 The four optical sensors S1, S2, S3, and S4, located closest to (i.e., at the shortest distance) the LED plant growth promoter 1, have the same direct LED light intensity range (lx1, lx2, lx3, lx4) and are within the maximum direct LED light intensity range. After communication between each optical sensor Si,i = 1, 2, 3, 4 and its respective zone controller Ci,i = 1, 2, 3, 4, the zone controller Ci controls the color change of the electrochromic units ECi,i = 1, 2, 3, 4. This ensures that the transmittance exhibited by each electrochromic unit ECi after electrochromic modification is at its minimum. Thus, the light emitted by the LED plant growth promoter 1 is adjusted to its weakest level when passing through each electrochromic unit ECi. The electrochromic behavior of the four electrochromic units EC1, EC2, EC3, and EC4 is as follows: Figure 4 As shown.
[0037] Similarly, in Figure 5 In the example, the four plants P1, P2, P3, and P4 to be supplemented with light are all at the same distances d1, d2, d3, and d4 from the LED plant growth promoter 1 (i.e., d1 = d2 = d3 = d4), and the control... Figure 1The four optical sensors S1, S2, S3, and S4 are at the furthest distance (i.e., the longest distance) from the LED plant growth promoter 1. The direct light intensity ranges lx1, lx2, lx3, and lx4 determined by these sensors are the same and within the minimum direct light intensity range for the LED. After communication between each optical sensor Si,i = 1, 2, 3, 4 and its respective zone controller Ci,i = 1, 2, 3, 4, the zone controller Ci controls the color change of the electrochromic units ECi,i = 1, 2, 3, 4. This ensures that the transmittance exhibited by each electrochromic unit ECi after electrochromic modification is at its maximum. Thus, the light emitted by the LED plant growth promoter 1 is adjusted to the minimum level of weakness when passing through the electrochromic units ECi. The electrochromic behavior of the four electrochromic units EC1, EC2, EC3, and EC4 is as follows: Figure 6 As shown.
[0038] comprehensive Figures 1 to 6 In this situation, Figure 7 The four possible electrochromic states of each electrochromic unit ECi are given. Figure 7 In this context, the electrochromic states are T1, T2, T3, and T4. For example... Figure 7 As shown, from top to bottom, they are T1 (shortest distance di), T2 (second shortest distance di), T2 (second longest distance di), and T4 (longest distance di). That is, the larger (or longer) the distance di, the lighter the color change of the electrochromic unit ECi, which means higher transmittance.
[0039] The distance di, the direct illumination intensity range lxi of the LED, and the transmittance lxi exhibited after electrochromism of each electrochromic unit ECi can be determined according to the actual situation. For example, the distance di and the direct illumination intensity range of the LED can be in a linear relationship. The smaller the distance di, the larger the direct illumination intensity range lxi of the LED, and the darker the color exhibited after electrochromism of each electrochromic unit ECi and the smaller the transmittance. That is to say, the distance di and the direct illumination intensity range lxi of the LED can form a linear function relationship. Similarly, the direct illumination intensity range lxi of the LED and the transmittance exhibited after electrochromism of each electrochromic unit ECi can also form a linear function relationship. Of course, the design can also be simplified. For example, the distance di is set into multiple sections according to the actual situation. For each section, a single-value direct illumination intensity range lxi of the LED is given, and the transmittance exhibited after electrochromism of the corresponding electrochromic units ECi can be given a range. Further, the transmittance exhibited after electrochromism of the corresponding electrochromic units ECi forms a linear relationship with each section. For example, when the distance di is in the range of 0 - 3m, the direct illumination intensity range lxi of the LED is 12500 lx (the specific performance of the LED plant growth promoting lamp 1 is also selected accordingly), and the transmittance exhibited after electrochromism of each electrochromic unit ECi is 1 - 5%; when the distance di is in the range of 4 - 7m, the direct illumination intensity range lxi of the LED is 11000 lx, and the transmittance exhibited after electrochromism of each electrochromic unit ECi is 10 - 20%; when the distance di is in the range of 7 < di ≤ 10m, the direct illumination intensity range lxi of the LED is 9000 lx, and the transmittance exhibited after electrochromism of each electrochromic unit ECi is 30 - 40%; when the distance di is in the range of 10 < di ≤ 12m, the direct illumination intensity range lx1 of the LED is 8000 lx, and the transmittance exhibited after electrochromism of each electrochromic unit ECi is 55 - 65%. The specific value of the distance di and the specific value of the direct illumination intensity range lx1 of the LED will be selected, for example but not limited to, according to the type of the plant Pj to be supplemented with light, as long as the irradiation intensity is appropriate.
[0040] The LED plant growth promoting lamp 1 can adopt any commercially available LED plant growth promoting lamp. For example, Xuyu Optoelectronics 2835 / 3030 TOP LED.
[0041] The optical sensor Si can use any well-known optical sensor for distance measurement to determine the aforementioned distance di. For example, the Keyence laser distance measurement sensor with a sensing distance meeting the requirements. Figure 1 、 Figure 3 和 Figure 5In this context, distance di is the distance between the highest point of the plant Pj to be supplemented with light and the horizontal plane where the LED plant growth promoter 1 is located. Specifically, the optical sensor Si can store the distance between its installation position and the horizontal plane where the LED plant growth promoter 1 is located. The optical sensor Si measures the vertical distance D between the highest point of the plant Pj to be supplemented with light and the optical sensor Si. The difference between the vertical distance D between the installation position of the optical sensor Si and the horizontal plane where the LED plant growth promoter 1 is located and the vertical distance D between the highest point of the plant Pj to be supplemented with light and the optical sensor Si is the distance di. Furthermore, the optical sensor Si can pre-store the LED direct illumination intensity range lxi and the correspondence between distance di and the LED direct illumination intensity range lxi.
[0042] Each electrochromic unit ECi can be made of any known and suitable electrochromic glass with internal control circuitry. The control circuitry can be, for example, the circuit disclosed in CN116300239A.
[0043] like Figures 1 to 6 As shown, in one example, multiple electrochromic units EC1, EC2, ..., ECn are arranged in a two-dimensional array in the same plane. In another example, not shown, multiple electrochromic units EC1, EC2, ..., ECn are arranged in a single row in the same plane.
[0044] In one example, multiple electrochromic units EC1, EC2, ..., ECn constitute a single integrated structure.
[0045] Each zone controller Ci can be a known controller capable of communicating with the control circuitry in its respective optical sensor Si and its respective electrochromic unit ECi.
