Description

Technical Field

[0001] This utility model relates to the field of cultivation equipment technology, and in particular to a dynamic spectral supplementary lighting device for rose flower bud differentiation. Background Technology

[0002] In greenhouse or polytunnel cultivation of roses, light conditions directly affect the growth pattern of the plants, especially during the critical stage of flower bud differentiation, which determines the yield of flowers and the quality of cut flowers. Artificial lighting has become an indispensable routine agricultural management method in the cultivation system.

[0003] Currently, the conventional supplemental lighting equipment used in cultivation systems is mainly single-channel LED plant lights with fixed spectral ratios, or multi-channel LED supplemental lighting fixtures that integrate multiple light-emitting chips. These multi-channel supplemental lighting devices usually require a dedicated electronic control center to light up or turn off specific color LED strips at different times by setting time programs or switching commands, thereby achieving the switching of the ambient supplemental lighting spectrum.

[0004] However, the spectral adjustment of existing supplemental lighting devices relies entirely on complex multi-channel electronic control circuits and the combination and switching of a large number of LED lamp arrays, resulting in high manufacturing costs and cumbersome fault maintenance. Moreover, this switching method based on circuit start-stop cannot provide a continuously fluctuating physical dynamic spectral environment for the rose canopy. Utility Model Content

[0005] The main purpose of this invention is to provide a dynamic spectral supplementary lighting device for rose flower bud differentiation, which aims to solve the problem that existing supplementary lighting devices rely on complex multi-channel electronic control circuits and densely arrayed LED beads to change the spectrum.

[0006] To achieve the above objectives, this utility model provides a dynamic spectral supplemental lighting device for rose flower bud differentiation. The supplemental lighting device is installed within a rose cultivation system, which includes a cultivation frame, cultivation trays, and a movable rod. The cultivation trays are movably mounted on the cultivation frame via the movable rod. The supplemental lighting device includes:

[0007] A supplementary lighting base, which is movably connected to a movable rod;

[0008] A supplemental lighting assembly is connected to a supplemental lighting base. The supplemental lighting assembly includes a supplemental lighting tube, a supplemental lighting head, and an adjustment component. The supplemental lighting head is disposed on the supplemental lighting base, the supplemental lighting tube is disposed between two supplemental lighting heads, and the adjustment component is used to adjust the angle of the supplemental lighting tube to promote flower bud differentiation of roses.

[0009] Optionally, the adjustment component includes a drive unit, an output gear, an adjustment gear, and a dynamic unit. The output end of the drive unit is connected to the output gear, the dynamic unit is disposed on the adjustment gear, and the output gear meshes with the adjustment gear to realize the rotation of the dynamic unit on the outer periphery of the supplementary light tube through the drive unit.

[0010] Optionally, the dynamic unit includes several dynamic plates, which are arranged in a circular array around the central axis of the supplementary light tube.

[0011] Optionally, the dynamic unit further includes support rings respectively disposed at both ends of the dynamic plate, and the two ends of the plurality of dynamic plates are respectively fixedly connected to the support rings on the same side to form a cage-like structure, and the supplementary light tube is coaxially inserted inside the cage-like structure.

[0012] Optionally, the dynamic plate is provided with alternating light-transmitting bands and filter areas along its axial or circumferential direction, and the filter areas on different dynamic plates have different transmission spectra, so as to dynamically modulate the light emitted by the supplementary light tube when the dynamic unit rotates around the supplementary light tube.

[0013] Optionally, the driving unit includes a servo motor or a stepper motor, and the driving unit is configured to drive the dynamic unit to rotate at a preset speed on the outer periphery of the supplementary light tube, so that the quality of the light irradiated onto the rose canopy fluctuates periodically.

[0014] Optionally, the supplementary lighting assembly may further include a supplementary lighting cover.

[0015] Optionally, both the dynamic plate and the fill light cover have a reflective layer on their end faces.

[0016] Optionally, the supplemental lighting device further includes a reflector, which is disposed on the side of the upper end of the cultivation tray.

[0017] Optionally, the reflector has a concave arc surface structure on the side facing the cultivation tray, and the focusing area of ​​the reflector faces the rose canopy inside the cultivation tray, so as to focus the dynamic spectral light modulated by the dynamic unit to the flower bud differentiation point of the rose.

[0018] The beneficial effects that this utility model can achieve are as follows:

[0019] This invention solves the technical problem of traditional fixed light sources being unable to accurately match the height and light-receiving parts of roses at different growth stages due to rigid lighting direction. It utilizes a supplementary lighting device installed within a cultivation system including a cultivation rack, cultivation tray, and movable rod. The supplementary lighting assembly consists of a supplementary lighting tube, a supplementary lighting head mounted on the supplementary lighting base, and adjustment components. The adjustment components flexibly adjust the spatial angle of the supplementary lighting tube between the two supplementary lighting heads. This achieves a highly flexible and targeted directional supplementary lighting effect, avoiding ineffective light loss to non-target areas and fundamentally improving the light energy utilization efficiency of the entire device. Furthermore, this extremely stable and flexibly adjustable basic architecture not only effectively reduces the deployment difficulty of the device but also provides a very solid and indispensable physical structural foundation for the subsequent introduction of a dynamic spectral modulation unit, thus ensuring that roses receive the most optimized targeted light stimulation during flower bud differentiation.

[0035] Please refer to the attached document as well. Figures 1 to 5 This embodiment provides a dynamic spectral supplementary lighting device 4 for rose flower bud differentiation. The supplementary lighting device 4 is installed within a rose cultivation system, which includes a cultivation frame 1, a cultivation tray 2, and a movable rod 3. The cultivation tray 2 is movably mounted on the cultivation frame 1 via the movable rod 3. The supplementary lighting device 4 includes:

[0036] Fill light base 41, which is movably connected to the movable rod 3;

[0037] A supplementary lighting component 42 is connected to the supplementary lighting base 41. The supplementary lighting component 42 includes a supplementary lighting tube 421, a supplementary lighting head 422, and an adjustment component 423. The supplementary lighting head 422 is disposed on the supplementary lighting base 41, the supplementary lighting tube 421 is disposed between the two supplementary lighting heads 422, and the adjustment component 423 is used to adjust the angle of the supplementary lighting tube 421 to promote the differentiation of rose flower buds.

[0038] It should be noted that in the traditional rose flower bud differentiation stage, the existing supplemental lighting device 4 relies on the combination and switching of multi-channel electronic control circuits and densely distributed LED light bead arrays to achieve spectral adjustment. The spectral switching process is entirely based on circuit start-stop control, which significantly increases the equipment manufacturing cost and complicates fault maintenance. Furthermore, this switching method cannot generate a continuously fluctuating physical dynamic spectral environment, thereby affecting the light quality regulation of the flower bud differentiation physiological process.

[0039] Based on the above problems, this embodiment provides a dynamic spectral supplementary lighting device 4 for rose flower bud differentiation. In actual greenhouse or polytunnel agriculture applications, the supplementary lighting device 4 is installed entirely within the rose cultivation system. The cultivation system serves as the basic platform for rose growth, primarily providing the necessary growth environment and physical support structure for the plants. Specifically, the cultivation system typically includes a cultivation rack 1, cultivation trays 2, and movable rods 3. To adapt to the specific spatial height requirements of roses at different stages from vegetative growth to reproductive growth, the cultivation trays 2 are movably mounted on the cultivation rack 1 via the movable rods 3. In actual assembly and operation, the cultivation trays 2 can be placed on the movable rods 3 and fixed using simple snap-fit ​​or limiting structures, or designed to slide on the movable rods 3.

[0040] For the supplemental lighting device 4, the device first includes a supplemental lighting base 41, which serves as the supporting base for the entire device and is movably connected to the movable rod 3 of the cultivation system. In a specific implementation, the supplemental lighting base 41 can be designed with a sleeve structure, which can be directly fitted onto the movable rod 3 and locked in position using a manual knob or fastening bolt. As an equivalent mechanical alternative, the supplemental lighting base 41 can also be configured as a clamping mechanism to physically clamp the movable rod 3. This movable connection structure allows the operator to manually slide, position, and relock the supplemental lighting device 4 along the movable rod 3 without the aid of complex tools, ensuring that the emitted light is always kept within the optimal light distance range from the rose canopy.

[0041] Based on the fill light base 41, the device is further equipped with a fill light assembly 42, which is connected to the fill light base 41. To ensure structural stability and ease of maintenance, the fill light assembly 42 can be rigidly fixed to the fill light base 41 using bolts, rivets, or welding to form a stable whole; or more preferably, it can be designed to be detachably connected to the fill light base 41 by snap-fit ​​or plug-in methods. The fill light assembly 42 is mainly composed of three key parts: a fill light tube 421, a fill light head 422, and an adjustment component 423. The fill light head 422 is mounted on the fill light base 41 and is usually a fixed bracket with mechanical support function. It can also integrate a power interface or related drive control circuit.

[0042] The supplementary light tube 421, as the main light-emitting body that actually generates light, is horizontally positioned between the two supplementary light heads 422. Its two ends are physically inserted into or fixed in the supplementary light heads 422. In specific application scenarios, the supplementary light tube 421 can be an LED light strip with specific spectral output capabilities or a traditional fluorescent tube. More importantly, in order to overcome the limitation of traditional fixed light sources being unable to accurately illuminate, an adjustment component 423 is specially introduced into the supplementary light assembly 42. This adjustment component 423 is mainly used to adjust the spatial angle of the supplementary light tube 421. From the perspective of mechanical connection and operation principle, the adjustment component 423 can be specifically implemented as a hinge structure, allowing the supplementary light tube 421 to be manually tilted and adjusted in the vertical plane; or it can be implemented as a ball-and-socket joint mechanism, giving the supplementary light tube 421 multi-dimensional omnidirectional manual angle adjustment capability.

[0043] Based on the above structure, this embodiment constructs a highly flexible and easily deployable directional lighting platform through the cooperation of purely mechanical physical structural components without introducing a complex electronic control system. By sliding the lighting base 41 along the movable rod 3 and finely adjusting the angle of the lighting tube 421 by the adjustment component 423, the operator can directly and accurately guide and focus the light onto the canopy of the rose plant and its core area of ​​flower bud differentiation. This not only fundamentally improves the light energy utilization efficiency of the equipment, but also lays the physical structural foundation for the subsequent introduction of a dynamic spectral modulation unit.

[0044] In this embodiment, the adjustment component 423 includes a drive unit 4231, an output gear 4232, an adjustment gear 4233, and a dynamic unit 4234. The output end of the drive unit 4231 is connected to the output gear 4232, and the dynamic unit 4234 is disposed on the adjustment gear 4233. The output gear 4232 meshes with the adjustment gear 4233 so that the drive unit 4231 realizes the rotation of the dynamic unit 4234 on the outer periphery of the supplementary light tube 421.

[0045] Understandably, the drive unit 4231, as the power source of the entire system, has its output end tightly connected to the output gear 4232, ensuring that the rotational power generated by the drive unit 4231 can be transmitted to the output gear 4232 without loss. Subsequently, the output gear 4232 meshes with the adjusting gear 4233, transmitting the power of the drive unit 4231 to the adjusting gear 4233. Since the dynamic unit 4234 is mounted on the adjusting gear 4233, the rotation of the adjusting gear 4233 will directly drive the dynamic unit 4234 to rotate around the outer periphery of the supplementary light tube 421. Through this mechanical transmission method, the continuous or intermittent operation of the drive unit 4231 can precisely control the rotation of the dynamic unit 4234, thereby achieving dynamic modulation of the light emitted by the supplementary light tube 421. This design enables the supplementary light device 4 to not only adjust the angle of the supplementary light tube 421, but also to dynamically intervene at the light quality level, providing a more precise and controllable light environment for rose flower bud differentiation.

[0046] In this embodiment, the dynamic unit 4234 includes a plurality of dynamic plates 4235, which are arranged in a circular array around the central axis of the supplementary light tube 421.

[0047] Understandably, when the drive unit 4231 drives the dynamic unit 4234 to rotate around the supplementary light tube 421 through the meshing of the output gear 4232 and the adjusting gear 4233, the dynamic plates 4235, being arranged in a circular array, can continuously block, filter, or reflect the light emitted by the supplementary light tube 421 in a preset trajectory and sequence. This circular array structure ensures that the light modulation around the supplementary light tube 421 is uniform and continuous during the rotation of the dynamic unit 4234, avoiding the problem of insufficient or excessive light modulation in local areas. In this way, the circular array distribution of the dynamic plates 4235, combined with the rotational motion of the drive unit 4231, jointly achieves dynamic spectral modulation of the light from the supplementary light tube 421, providing a precise and controllable light environment for rose flower bud differentiation.

[0048] In this embodiment, the dynamic unit 4234 further includes support rings 4236 respectively disposed at both ends of the dynamic plate 4235. The two ends of the plurality of dynamic plates 4235 are respectively fixedly connected to the support rings 4236 on the same side to form a cage-like structure. The supplementary light tube 421 is coaxially inserted inside the cage-like structure.

[0049] It should be noted that the drive unit 4231 drives the dynamic unit 4234 mounted on the adjusting gear 4233 to rotate through the meshing of the output gear 4232 and the adjusting gear 4233. The dynamic unit 4234 is composed of several dynamic plates 4235 and support rings 4236 respectively mounted at both ends of the dynamic plates 4235. The two ends of the several dynamic plates 4235 are respectively connected to the support rings 4236 on the same side by a fixed connection, thereby forming a cage-like structure with a stable structure and a certain rigidity. The supplementary light tube 421 is coaxially inserted into the inside of the cage-like structure to ensure that its central axis coincides with the rotation axis of the cage-like structure. When the drive unit 4231 is started, the entire cage structure (i.e., the dynamic unit 4234) consisting of the support ring 4236 and the dynamic plate 4235 will rotate around the stationary supplementary light tube 421. Since the dynamic plate 4235 has light-transmitting strips and light-filtering areas alternately arranged along its axial or circumferential direction, and the light-filtering areas on different dynamic plates 4235 have different transmission spectra, when the cage structure rotates, these dynamic plates 4235 will periodically block and filter the light emitted by the supplementary light tube 421.

[0050] The support ring 4236 provides robust end support for the dynamic plate 4235, ensuring its positional accuracy and structural stability during high-speed or long-term rotation. This effectively prevents deformation, loosening, or displacement of the dynamic plate 4235 due to centrifugal force, vibration, or its own gravity, thus guaranteeing the accuracy and reliability of dynamic spectral modulation. The supplementary light tube 421 is coaxially inserted within the cage-like structure, ensuring that light emitted from the supplementary light tube 421 is uniformly and without deviation modulated through the dynamic plate 4235, avoiding light leakage or uneven modulation. This structure allows the dynamic unit 4234 to rotate stably around the supplementary light tube 421 as a whole, achieving periodic dynamic fluctuations in the light quality of the rose canopy, thereby effectively promoting rose flower bud differentiation.

[0051] In this embodiment, the dynamic plate 4235 is provided with light-transmitting strips and filter areas alternately along its axial or circumferential direction, and the filter areas on different dynamic plates 4235 have different transmission spectra, so as to dynamically modulate the light emitted by the supplementary light tube 421 when the dynamic unit 4234 rotates around the supplementary light tube 421.

[0052] Because each filter region has a preset different transmission spectrum, the spectral composition of the light illuminating the rose canopy will exhibit regular dynamic changes as the dynamic unit 4234 continues to rotate. This design allows the supplemental lighting device 4 to provide precise and diverse spectral stimulation according to the specific needs of rose flower bud differentiation, rather than a single or static spectrum, thus overcoming the limitations of traditional supplemental lighting methods in spectral control and providing a more optimized light environment for the growth and development of roses.

[0053] In this embodiment, the driving unit 4231 includes a servo motor or a stepper motor. The driving unit 4231 is configured to drive the dynamic unit 4234 to rotate at a preset speed on the outer periphery of the supplementary light tube 421, so that the light quality irradiated onto the rose canopy exhibits periodic dynamic fluctuations.

[0054] Based on the above structure, the light illuminating the rose canopy will no longer be static, but will exhibit predictable and repeatable periodic dynamic fluctuations, thereby providing precise and stable spectral stimulation for rose flower bud differentiation. This precisely controlled dynamic spectral supplementary lighting method effectively solves the problems of inaccurate and unstable light quality modulation in traditional supplementary lighting schemes, and provides a more optimized light environment for the growth and development of roses.

[0055] In this embodiment, the supplementary lighting component 42 also includes a supplementary lighting cover 424. Through its structural design, the supplementary lighting cover 424 can collect these scattered light rays and redirect them to the canopy area of ​​the rose, ensuring that the dynamic spectrum light rays precisely modulated by the dynamic unit 4234 can act on the rose more concentratedly and efficiently, avoiding the waste of light energy and making the light distribution more uniform and controllable.

[0056] Both the dynamic plate 4235 and the fill light cover 424 have reflective layers on their end faces. When the fill light tube 421 emits light, during the spectral modulation process of this light through the dynamic plate 4235 of the dynamic unit 4234, some of the light may propagate along the axial direction of the fill light tube 421 and may escape from the end face of the dynamic plate 4235. At this time, the reflective layer on the end face of the dynamic plate 4235 can reflect this light back into the interior of the fill light assembly 42, giving it a chance to be reused or guided to the target area.

[0057] The supplemental lighting device 4 also includes a reflector 43, which is disposed on the side of the upper end of the cultivation tray 2. The reflective surface of the reflector 43 redirects these scattered light rays, converging them and projecting them onto the rose canopy and flower bud differentiation area within the cultivation tray 2. In this way, the light energy emitted by the supplemental lighting device 4 is utilized more fully, reducing light spillage and waste, thereby improving the uniformity and intensity of light.

[0058] The reflector 43 has a concave arc surface structure on the side facing the cultivation tray 2, and the focusing area of ​​the reflector 43 faces the rose canopy in the cultivation tray 2, so as to focus the dynamic spectrum light modulated by the dynamic unit 4234 to the flower bud differentiation point of the rose.

[0059] When the light emitted from the supplemental lighting tube 421 is modulated by the dynamic unit 4234, some of the light directly illuminates the rose canopy, while the other part, scattered outwards, is projected onto the concave arc surface of the reflector 43. Due to the optical properties of this arc surface structure, these scattered rays are effectively reflected and redirected. Furthermore, by precisely designing the installation position and curvature of the reflector 43, the focusing area where its light converges can be precisely directed towards the rose canopy within the cultivation tray 2, especially the area where rose flower buds differentiate. This structural configuration ensures that the dynamically modulated light spectrum, finely modulated by the dynamic unit 4234, can be efficiently collected, converged, and concentrated onto the target area, avoiding unnecessary scattering and energy loss of light within the cultivation system. This ensures that the specific spectrum and light intensity required for rose flower bud differentiation can accurately and effectively act on the target area.

[0060] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
