Description

Technical field

[0001] The present utility model relates to the technical field of plant breeding, in particular a plant supplementary lighting roller lamp. State of the art

[0002] Sunlight is an indispensable key factor in the growth and development process of plants. Plants must carry out photosynthesis by absorbing sunlight to generate the energy required for growth. In certain plants, the daily duration of photosynthesis can reach up to 16 hours; however, the maximum natural daylight period is only 12-13 hours, which is insufficient to meet the light requirements of plant growth.

[0003] To solve this problem, it is necessary to use artificial supplemental lighting when cultivating plants such as vegetables, fruits, and camellias in greenhouses. This serves both to extend the exposure time of plants, thereby increasing the duration of photosynthesis, and to reduce environmental influences on plant growth. This method allows both the supplemental lighting time and the plant growth environment to be kept in an artificially controllable state. Based on this need, supplemental plant lighting lamps were developed. These lamps can simulate sunlight and irradiate plants, effectively extending the duration of photosynthesis and consequently promoting plant growth and development.Since installing supplemental plant lighting lamps indoors simplifies cable routing and reduces the adverse effects of extreme weather conditions such as storms and heavy rain on the supplemental plant lighting system, the installation of supplemental plant lighting lamps usually takes place indoors.

[0004] Currently, most supplemental plant lighting lamps known in the prior art are of a fixed design. Typically, they are positioned directly in the upper area of ​​indoor spaces to illuminate plants from top to bottom, or mounted directly on walls for lateral illumination. These fixed installations usually employ rigid structures such as bolts, brackets, and similar fasteners to fix the lighting devices directly to walls, ceilings, or growing racks. Once installed, the position and angle of the lighting device cannot be adjusted. For example, in greenhouse environments, lighting devices are often permanently attached to crossbeams, making it difficult to move them to accommodate changes in plant height or adjustments to the growing arrangement.This stationary construction has significant disadvantages, as it cannot flexibly adapt to the different supplemental lighting requirements of various plants in different growth phases. Content of the present utility model

[0005] In view of this, the present utility model provides a plant supplementary lighting roller lamp, wherein the present utility model enables the rolling up of light strips and also ensures the irradiation of most plants to carry out photosynthesis, thereby ensuring that plants can grow normally without impairment.

[0006] To solve the aforementioned technical problem, the present utility model provides a plant supplementary lighting roller blind lamp, comprising: - a housing which has a hollow chamber inside; - several rotating shafts arranged rotatably in the chamber as cylindrical structures, with a drive structure provided in the chamber to drive the rotation of the rotating shafts; - several PCB boards that are firmly connected to the outer wall surface of the rotating shaft and can rotate together with the rotating shaft, the PCB boards being designed to control the operation of the light strips. - several flexible light strips connected to the PCB boards, wherein the rotation of the rotating shaft causes the light strips to be wound around the rotating shaft, allowing the light strips to be wound up or unwound, wherein the housing has movement holes corresponding to the light strips, with one end of the movement hole being connected to the chamber and the other end to the outer wall surface of the housing, and the light strips being able to move within the movement holes.

[0007] The rotating shaft is a cylindrical structure, wherein the drive structure comprises a tubular motor fixed in the chamber, which is located inside the rotating shaft and is arranged on the same axis as the rotating shaft, wherein the output shaft of the motor is connected to a drive wheel, and the drive wheel is connected to the inner wall surface of the rotating shaft, and the motor can drive the rotation of the rotating shaft via the drive wheel.

[0008] Corresponding to the rotating shaft, two support elements are arranged in the chamber, the two support elements being positioned on opposite sides of the rotating shaft, the rotating shaft being rotatably connected to the support elements at both ends, the two support elements providing support for both ends of the rotating shaft, and the end of the motor being rigidly connected to one of the support elements.

[0009] Each of the two support elements has an end cap wheel rotatably arranged, the end cap wheels being fixedly connected to the end of the rotating shaft and the motor being rotatably arranged in one of the end cap wheels.

[0010] Furthermore, a slip ring is arranged in the rotating shaft, which can rotate together with the rotating shaft to prevent the cable harness from becoming tangled.

[0011] A counterweight is arranged at each end of the light strips furthest from the rotating shaft, the counterweight being designed to prevent the light strips from oscillating.

[0012] Several light strips are arranged on the rotating shaft, with the counterweights at the lower end of the several light strips connected to each other in order to prevent fluctuations and to close the movement bore after winding.

[0013] A boundary structure is provided in the movement bore corresponding to the light strip, the boundary structure being designed to prevent displacement of the light strip during the winding process.

[0014] The limiting structure comprises a slider arranged to slide on a side wall of the movement bore, wherein the slider has two limiting bars, the light strip is positioned between the two limiting bars, and the slider has a fastening element for fixing the position of the slider.

[0015] The light strip consists of several vertically arranged light bands, the light bands being a double-sided light structure, and the chamber also includes a control module through which commands can be sent to the PCB board to control one-sided or double-sided illumination of the light bands, whereby any single or multiple segments of the light bands on the light strip can be illuminated.

[0016] In summary, the present application has at least one of the following advantageous technical effects compared to the prior art: 1. Flexible adjustment of the auxiliary lighting position and angle: The drive structure, which sets the rotating shaft in motion, allows the light strips to be wound up or down, enabling flexible adjustment of the position and angle of the light strips to optimally meet the different supplementary lighting requirements of various plants in different growth phases and to effectively prevent uneven lateral illumination of parts of the plants, which would impair the photosynthetic efficiency of the plants. 2. Structurally stable and operationally reliable design: A drive wheel is attached to the motor's output shaft. This drive wheel is connected to the inner surface of the rotating shaft, and the motor uses the drive wheel to rotate the shaft. This design ensures a rigid connection between the motor and the rotating shaft, as well as stable power transmission. Simultaneously, two support elements are provided within the chamber corresponding to the rotating shaft, offering stable support for both ends. Furthermore, an end cap wheel is rotatably mounted to each of these support elements. The end cap wheel is rigidly connected to the end of the rotating shaft, and the motor is rotatably mounted within one of the end cap wheels. This further enhances structural stability and ensures the operational reliability of the entire device. 3. Avoidance of cable tangling and light strip vibrations: The rotating shaft is equipped with a slip ring that rotates with it to prevent the cable harness from becoming tangled. During the winding and unwinding of the light strips, the cable harness moves in accordance with the rotation of the rotating shaft. The slip ring effectively prevents tangling and knotting of the cable harness, ensures the stability of the electrical connection, and reduces cable harness-related interference. Each light strip has a counterweight at its end furthest from the rotating shaft, which serves to prevent the strips from swaying. When multiple light strips are mounted on the rotating shaft, the counterweights are connected to each other at their lower ends.These not only prevent vibrations, but can also close the movement holes after being rolled up, thus ensuring both the operational stability of the light strips and achieving a sealing effect that prevents the ingress of dust and other contaminants into the chamber. 4. Flexible and controllable light strip emission: The light strip consists of several vertically arranged light bands with a double-sided light structure. A control module is also located within the chamber. This module transmits commands to the PCB, controlling the one-sided or two-sided light emission of the light bands and activating any section or multiple segments of the light strip. This design allows for flexible and versatile light emission from the strip, enabling precise control of the lighting area and intensity according to the varying lighting requirements of different plants. This provides a more suitable lighting environment, further increases the efficiency of plant photosynthesis, and promotes plant growth and development. 5. The boundary structure of the movement bore ensures the operation of the light strips: The movement bore incorporates a boundary structure corresponding to the light strips, which serves to prevent displacement of the light strips during the winding process. During winding, this boundary structure ensures that the light strips move along the correct path, preventing displacement, guaranteeing neat and smooth winding, and extending the lifespan of the light strips.

Detailed descriptions

[0017] To clarify the objectives, technical solutions, and advantages of the embodiments of this utility model, the following sections refer to the Fig. Sections 1-3 of the embodiments of this utility model clearly and completely describe the technical solutions of the embodiments of this utility model. Obviously, the described embodiments represent a subset of the embodiments of this utility model and not all embodiments. Based on the described embodiments of this utility model, all other embodiments developed by those skilled in the art in this field fall within the scope of protection of this utility model.

[0018] This embodiment provides an additional plant lighting roller blind lamp, as shown in the Fig.Figures 1-3 show: comprising a housing 1 with a cuboid structure, which internally has a hollow chamber 2, wherein a rotating shaft 3 is arranged horizontally rotatably in the chamber 2, which is mounted as a cylindrical structure rotating in the chamber 2, wherein a PCB board 4 is arranged horizontally on the outer wall surface of the rotating shaft 3, wherein the PCB board 4 is aligned parallel to the axis of the rotating shaft 3, wherein several light strips 5 are connected to the PCB board 4, wherein the several flexible light strips 5 are arranged linearly, wherein when the rotating shaft 3 rotates, it drives the light strips 5 via the PCB board 4, thereby enabling the light strips 5 to be wound up or unwound, and wherein the housing 1 has movement bores corresponding to the light strips 5, one end of which is connected to the chamber 2 and the other end of which is connected to the outer wall surface of the housing 1.the light strips 5 can move within the movement bore.

[0019] Chamber 2 houses a power supply module and a control module, which work together in a coordinated manner to ensure stable operation and flexible control of the entire device. The power supply module, as the core energy source for the entire plant supplemental lighting roller lamp, is responsible for providing stable electrical energy to all components. It features powerful electrical energy storage and distribution capabilities and can precisely output the appropriate voltage and current according to the varying power consumption requirements of the different components. The control module is connected to the wiring harness of the motor 6 and the wiring harness of the light strip 5.The motor 6's wiring harness is specifically designed to supply power to the motor 6, which acts as a key component for driving the rotation of the rotating shaft 3. Its stable operation is directly related to the winding and unwinding of the light strip 5. The control module supplies the motor 6 with stable electrical energy via its wiring harness, ensuring that the motor 6 can start, operate, and stop correctly under various operating conditions. For example, when the position of the light strip 5 needs to be adjusted, the control module quickly activates the power supply module to indirectly provide sufficient drive force to the motor 6. This allows the motor 6 to precisely rotate the rotating shaft 3, enabling the rapid winding or unwinding of the light strip 5.

[0020] The cable harness of the LED strips 5 is connected to the PCB and supplies power to the LED strips 5. The LED strips 5 are the key component for the supplemental plant lighting system, whose light output directly influences the efficiency of plant photosynthesis. The control module transmits the electrical energy stably via the cable harness of the LED strips 5 to the PCB, which then controls the light emission of the LED strips 5.

[0021] Accordingly, the light strip can be permanently soldered to the PCB board or detachably attached to the PCB board, which facilitates maintenance or replacement of the light strip; i.e., the light strip can be fixed to the PCB board using bolts or connected to the PCB board by magnetic attachment or other fastening methods, as long as quick disassembly and assembly are possible.

[0022] Preferably, the light strip 5 is composed of several vertically arranged light bands. This design is not arbitrary, but rather the result of careful consideration to meet the diverse requirements of plant growth. During the plant growth process, differences exist in the absorption and utilization efficiency of light between plant leaves at different heights. For example, in the intensive growth phase, the upper leaves of plants, due to their more delicate structure, have different requirements for light intensity and quality compared to the more mature leaves in the middle and lower sections. The vertical arrangement of several light bands allows each individual light band to operate independently, providing targeted and suitable illumination for plant areas at different heights.

[0023] From a space utilization perspective, vertically arranged light strips allow for the full utilization of vertical space and ensure extended illumination coverage in limited areas. Compared to conventional horizontal arrangements, this design increases the effective projection area of ​​the light without increasing the horizontal dimensions of the device and is particularly suitable for spatially compact growing environments such as greenhouses, indoor grow racks, etc. (Using the control module, any section of the light strip on light strip 5 can be precisely controlled for light emission. This means that, in practical applications, depending on the specific height and distribution of the plants, light strips can be selectively switched on or off at specific positions to achieve targeted illumination of the plants at the respective height.)

[0024] Furthermore, the vertical arrangement of multiple light strips facilitates layer-by-layer lighting control. In practical cultivation, different plant varieties or different growth phases of the same plant can have layer-by-layer differentiated lighting requirements. By independently controlling the light emission of each individual light strip, customized lighting concepts can be provided for different plant heights according to the actual needs of the plants, thereby optimizing the plants' growing environment and increasing cultivation efficiency and yield.

[0025] Furthermore, the light strips feature a bidirectional light emission structure, since in plant cultivation, plant leaves are not only distributed on the front of the plants, but also have numerous photosynthetic cells on the back. Conventional unidirectional light strips can only illuminate the upper surface of the plant leaves, while the underside of the leaves receives little light, thus limiting the efficiency of plant photosynthesis to a certain extent.

[0026] Light strips with a double-sided light structure are able to illuminate both the front and back of plant leaves simultaneously, allowing both sides to fully absorb light energy and thus significantly increasing the surface area and efficiency of photosynthesis. Studies show that double-sided illumination promotes the opening of stomata in plant leaves, enhances gas exchange, and facilitates the absorption of carbon dioxide and the release of oxygen, thereby further increasing the plants' rate of photosynthesis.

[0027] Furthermore, the double-sided light structure increases the uniformity of illumination. In cultivation environments, uniformity of light is crucial for plant growth. Uneven lighting can lead to unbalanced plant growth, with some areas growing lushly while others are stunted. The double-sided light strips can provide plants with light from multiple directions, reducing dark zones and ensuring that all parts of the plant receive relatively uniform illumination, thus promoting consistency and coordination of overall plant growth.

[0028] Controlling the light strip's color via the control module allows for a wider selection of light qualities for supplemental plant lighting. Different colored light has varying effects on plant growth and development; for example, violet light can promote anthocyanin synthesis and increase stress resistance. Yellow light, on the other hand, influences plant morphogenesis and photoperiod regulation.

[0029] The control module allows for flexible regulation of the color emitted by the light strip, according to the different growth phases and varietal characteristics of the plants. During the vegetative growth phase, the proportion of blue light can be increased to promote leaf and root development. Conversely, during the reproductive growth phase, the proportion of red light is increased to encourage flower bud formation and fruit development. Furthermore, customized color combinations can be developed based on the specific light quality requirements of different plants, providing them with more precise lighting conditions.

[0030] In particular, the rotary shaft 3 is a cylindrical structure extending through both ends, the drive structure comprising a tubular motor 6 fixed in the chamber 2, which is arranged inside the rotary shaft 3 and on the same axis as it, wherein a drive wheel 7 is provided on the output shaft of the motor 6, which is located inside the rotary shaft 3 and is rigidly connected to the inner wall of the rotary shaft 3, so that the motor 6 can provide support for the rotary shaft 3 via the drive wheel 7 and set it in rotation.

[0031] Furthermore, two support elements 8 are arranged in the chamber 2 corresponding to the rotating shaft 3, wherein both support elements 8 have a plate-shaped structure, the two support elements 8 are located on opposite sides of the rotating shaft 3, both ends of the rotating shaft 3 are rotatably connected to the support elements 8, the end of the motor 6 is rigidly connected to one of the support elements 8, whereby the two support elements 8 can provide support for both ends of the rotating shaft 3, so that the rotation of the rotating shaft 3 can be more stable, i.e. no misalignment occurs at either end of the rotating shaft 3.

[0032] Preferably, end cap wheels 9 are rotatably arranged on both support elements 8, wherein the motor 6 is rigidly connected to the support element 8 through one of the end cap wheels 9 and both ends of the rotating shaft 3 are rigidly connected to the end cap wheels 9, thereby providing stable support for both ends of the rotating shaft 3.

[0033] Accordingly, a slip ring 10 is also attached to the inner wall surface of the rotating shaft 3, which can rotate together with the rotating shaft 3, the cable harness of the motor 6 being guided through one of the support elements 8 and connected to the end of the motor 6, while the cable harness of the light strip 5 runs through another support element 8 and the end cap wheel 9 inside the rotating shaft 3, and this cable harness of the light strip 5 is also connected to the slip ring 10 inside the end cap wheel 9, whereby the slip ring 10 prevents the cable harness from becoming knotted inside the rotating shaft 3 during the rotation process of the rotating shaft 3 and thus makes proper control or power supply of the light strip 5 impossible.

[0034] Furthermore, each light strip 5 is provided with a counterweight 11 at a distance from the rotating shaft 3, wherein the counterweight 11 prevents the light strip 5 from oscillating during use, and wherein the counterweights 11 are connected to each other at the end faces of the lower end of the several light strips 5, thereby further preventing the light strips 5 from oscillating, and after the light strips 5 have been completely wound up by the rotating shaft 3, the counterweight 11 can close the movement bore, thereby preventing foreign bodies or airborne dust from entering the chamber 2 through the movement bore when no irradiation of the plants is required.

[0035] It is worth mentioning that a limiting structure is provided in the movement bore corresponding to the light strip 5, the limiting structure serving to prevent displacement of the light strip 5 during the winding process.

[0036] A limiting structure is provided in the movement bore corresponding to the light strip 5, the limiting structure serving to prevent displacement of the light strip 5 during the winding process.The limiting structure comprises a slider 12 arranged to slide on the inner wall surface of the movement bore, with a limiting rod 13 provided at each end of the slider 12. The light strip 5 can move up and down between the two limiting rods 13, ensuring that the light strip 5 moves along the correct path, preventing misalignment, guaranteeing a neat and smooth winding of the light strip 5, extending the service life of the light strip 5, and allowing the position of the slider 12 in the movement bore to be adjusted. After adjusting the position of the slider 12, it can be fixed in the movement bore by means of bolts.

[0037] Furthermore, it should be explained that, unless expressly specified and limited otherwise, the terms "assembly," "connection," and "connection" in the description of this utility model are to be understood in their broadest sense. For example, they may refer to a permanent connection, a detachable connection, or a one-piece connection; they may be a mechanical connection or an electrical connection; they may be a direct connection or an indirect connection through an intermediate medium; they may be the internal connection of two components. For a person skilled in the art, the specific meaning of the aforementioned terms in this utility model is to be understood according to the specific circumstances.

[0038] The foregoing are preferred embodiments of the present utility model. It should be noted that, for the average person skilled in the art in this technical field, various improvements and modifications could be made without deviating from the principles set forth in this utility model, and these improvements and modifications would also fall within the scope of protection of this utility model.
