Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-3 As shown, this utility model embodiment provides a plant cultivation supplementary lighting device, including a mounting base 1, a light-emitting structure 2, a rotating structure 5, an irradiation structure 3, a light-blocking plate 6, a linkage structure 4, and an identifier 7.

[0023] The light-emitting structure 2 is rotatably mounted inside the mounting base 1. The rotating structure 5 is installed at one end of the mounting base 1 along its length to drive the light-emitting structure 2 to rotate. The illumination structure 3 and the identifier 7 are both located at the bottom of the mounting base 1. Two light-blocking plates 6 are rotatably mounted on the front and rear sides of the mounting base 1, respectively. The linkage structure 4 is installed on the mounting base 1 to adjust the tilt angle of the light-blocking plates 6. The linkage structure 4 is used to drive the two light-blocking plates 6 to rotate synchronously to adjust the illumination range. The identifier 7 is suitable for image acquisition, and the acquired images can provide material for determining plant types and plant planting areas.

[0024] The light-emitting structure 2 includes a rotating shaft 21, a first lamp tube 22, a second lamp tube 23, and a third lamp tube 24. The rotating shaft 21 is rotatably mounted in the mounting base 1. The first lamp tube 22 and the second lamp tube 23 are symmetrically mounted on the rotating shaft 21. The third lamp tube 24 is respectively mounted on the front and rear sides of the first lamp tube 22 and the second lamp tube 23. There are four third lamp tubes 24. The first lamp tube 22 is suitable for emitting infrared light, the second lamp tube 23 is suitable for emitting ultraviolet light, and the third lamp tube 24 is suitable for adjusting the color of light emission.

[0025] The illumination structure 3 includes a first illumination port 31, a second illumination port 32, and a lampshade 33. The first illumination port 31 and the second illumination port 32 are both opened at the bottom of the mounting base 1, and the second illumination port 32 is located on both sides of the width direction of the first illumination port 31. The lampshade 33 is installed at the bottom of the mounting base 1 and corresponds to the positions of the first illumination port 31 and the second illumination port 32 respectively. The tilt angle from the first illumination port 31 to the second illumination port 32 is consistent with the tilt angle of the adjacent first lamp tube 22 and the second lamp tube 23. The identifier 7 is installed between the first illumination port 31 and the second illumination port 32.

[0026] As a further description of the above scheme, the first lamp tube 22 can emit near-infrared (NIR) and far-infrared (FIR) light by adjusting the wavelength of infrared light. Near-infrared (NIR) light can change the state of phytochromes during plant growth, transmit key environmental signals to the plant, and regulate the morphogenesis (such as height and branching) and development process (such as flowering and germination) of the plant, helping the plant to compete for survival in complex environments, thereby achieving the purpose of increasing yield, efficiency, and energy saving. Far-infrared (FIR) light can generate a thermal effect, increase the temperature of plant tissues and the surrounding environment. A suitable temperature can accelerate the rate of biochemical reactions, promote seed germination, root absorption of water and nutrients, and enhance photosynthetic efficiency.

[0027] As a further description of the above scheme, the second lamp 23 can emit long-wave ultraviolet (UV-A) and medium-wave ultraviolet (UV-B) light by adjusting the wavelength of ultraviolet light; long-wave ultraviolet (UV-A) can promote the synthesis of antioxidants such as anthocyanins and flavonoids, making the leaves and fruits of plants more vibrant in color (such as purple and red); medium-wave ultraviolet (UV-B) is an environmental stress signal. Under low-dose irradiation, plants will regard it as a kind of "training", which will greatly increase the synthesis of protective secondary metabolites and is a key tool for regulating morphology and improving quality.

[0028] As a further description of the above scheme, the third lamp tube 24 is a full-color RGB lamp tube or RGBW lamp tube, which can emit white light and various colored lights.

The second mounting plate 51 is installed at one end of the mounting base 1 along its length, and the second servo motor 52 is fixedly installed on the second mounting plate 51 and fixedly connected to the rotating shaft 21.

[0030] Please see Figure 1 and Figure 3As shown, the linkage structure 4 includes a rotating rod 41, a gear transmission assembly, and a drive component. The two rotating rods 41 are respectively mounted on two light-blocking plates 6.

The second gear 43 is rotatably mounted in the mounting base 1 and located between the third gear 44 and the first gear 42. The two third gears 44 mesh with each other, and the second gear 43 meshes with the third gear 44 and the first gear 42. This allows the two rotating rods 41 to rotate synchronously using the gear transmission assembly, so as to synchronously adjust the tilt angle of the two light-blocking plates 6.

[0032] Please see Figure 1 and Figure 3 As shown, the drive component includes a first mounting plate 45 and a first servo motor 46. The first mounting plate 45 is mounted on the left side of the mounting base 1, and the first servo motor 46 is mounted on the first mounting plate 45. The output section of the first servo motor 46 is connected to one of the two third gears 44, so that the first servo motor 46 can drive the third gear 44 to rotate, thereby driving the gear transmission assembly to operate.

[0033] Please see Figure 2-3 As shown, the rotating shaft 21 has several mounting slots 211, and the first lamp tube 22, the second lamp tube 23 and the third lamp tube 24 are all installed in the mounting slots 211. Installing the lamp tubes in the mounting slots 211 can prevent the lamp tubes from being bumped or knocked during the rotation of the rotating shaft 21.

[0034] Please see Figure 1-2 As shown, the bottom of the mounting base 1 is provided with a supplementary light groove 111. The supplementary light groove 111 is arranged in a semi-circular ring. The light-blocking plate 6 and the lamp cover 33 are both arranged in the supplementary light groove 111, and the two light-blocking plates 6 are located at the front and rear ends of the supplementary light groove 111 respectively. The light-blocking plate 6 can better define the supplementary light range by rotating in the supplementary light groove 111.

[0035] Please see Figure 1-2 As shown, a reflector 61 is provided on each of the two light-blocking plates 6 on opposite sides; the outwardly scattered light can fall more effectively into the supplementary lighting range after being reflected by the reflector 61, thereby improving the light utilization rate.

[0036] Please see Figure 1-2As shown, the mounting base 1 includes an irradiation component 11 and a mounting component 12. The mounting component 12 is fixedly mounted on the top of the irradiation component 11. The light-emitting structure 2, the irradiation structure 3, the linkage structure 4, the rotation structure 5, and the light-blocking plate 6 are all disposed on the irradiation component 11.

[0037] Please see Figure 1-2 As shown, a controller 8 is installed inside the mounting base 1. The first lamp tube 22, the second lamp tube 23, the third lamp tube 24, the identifier 7, the second servo motor 52, and the first servo motor 46 are all electrically connected to the controller 8.

[0038] As a further description of the marketable solution, the controller 8 in this application is a dedicated microcomputer that integrates color management algorithms, multi-channel power output, wireless communication protocols, and user experience programming. It can achieve color mixing and accurate color matching of the third lamp tube 24 while ensuring the operation control and power allocation of various electronic devices. In addition, the recognizer 7 set in this application includes an image acquisition device installed at the bottom of the mounting base 1 and a plant recognition-based storage medium mounted in the controller 8. The storage medium contains an algorithm program for obtaining plant categories using the acquired images. This algorithm program is commonly used and well-known in the field, and this application has not improved it, so it does not need to be described in detail.

[0039] The working process of the above-mentioned plant cultivation supplemental lighting device is as follows: When using this plant cultivation supplemental lighting device, the mounting base 1 must first be fixedly installed on a supplemental lighting bracket or robotic arm suitable for ensuring uniform supplemental lighting, so that the mounting base 1 is facing the plant to be supplemented with light. Then, the controller 8 and the identifier 7 are combined to identify and analyze the plant species to obtain the plant planting area and the plant's supplemental lighting needs. After that, the second servo motor 52 drives the rotating shaft 21 to rotate, adjusting the position of the lamp tubes and rotating the first lamp tube 22 or the second lamp tube 23 to the first irradiation port 31, so as to conveniently emit the ultraviolet light or infrared light required by the plant. At the same time, the third lamp tube 24 can also provide the plant with visible light of a specific color through the second irradiation port 32 to further maintain the plant's light requirements for growth. During this process, the operation of the first servo motor 46 can also drive the third gear 44 to rotate, thereby enabling the third gear 44 to work with the second gear 43 to drive the first gear 42 and the rotating rod 41 to rotate, so as to adjust the tilt angle of the light-blocking plate 6 to adjust the supplementary lighting area, thereby making the supplementary lighting area suitable for the planting area of ​​plants.
