Description

Technical Field

[0001] This utility model relates to the field of plant supplemental lighting, and in particular to an LED plant supplemental lighting fixture. Background Technology

[0002] Facility agriculture overcomes the limitations of natural conditions through artificial environmental control, enabling year-round continuous crop production. As light is a core element of plant photosynthesis, precise supply is crucial. In low-light environments, such as high-latitude winters, the lower layers of multi-layered cultivation, or enclosed vertical farms, plant supplemental lighting stands, as the core carriers of light energy transfer, must consider light source layout, light quality adaptation, and spatial light distribution optimization. With the advancement of LED technology, optical design, and plant photobiology research, supplemental lighting stands have evolved from simple "top coverage" to "three-dimensional light field construction." However, constrained by facility structure, cost, and the dynamic growth needs of plants, improving light energy utilization efficiency remains a pain point in the industry, driving the design of lighting stands towards intelligence, three-dimensionality, and self-adaptability.

[0003] In existing plant factories, supplemental lighting often uses multi-layer plant lighting racks to provide supplemental lighting for plants. The typical structure is arranged with the supplemental lights on top and the plants below, layer by layer. This relies on a "top-down" vertical irradiation mode. Some racks also use secondary optical design with lenses, such as a 120° divergence angle, to expand the coverage area of ​​a single light and illuminate more plants.

[0004] In the process of implementing the inventive technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. How to recover and utilize the light emitted by the supplemental lighting source that is not being used by the plants?

[0006] 2. How to use a grow light stand to supplement the light on the sides and bottom of plants? Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to provide an LED plant supplement light holder, which improves light energy utilization and achieves multi-directional supplementary lighting by setting a reflector with a special structure and a reasonable overall layout.

[0008] The purpose of this invention is to overcome the technical defects of low light energy utilization and difficulty in providing all-round light to plants in the existing technology, and to provide an LED plant supplement light holder that can effectively recover unused light and achieve multi-directional supplement light to plants.

[0009] This application provides a plant grow light stand, specifically comprising:

[0010] The light stand frame is used to support the plant planting rack and LED lighting panel to complete the tasks of crop planting and supplemental lighting.

[0011] LED lighting panels are installed on the lamp frame to provide supplemental lighting for the plants grown on the lamp frame.

[0012] A plant planting rack, mounted on the lamp holder frame, is located on the same side of the lamp holder frame as the LED lighting panel and is alternately arranged with it along the vertical direction on the lamp holder frame for planting plants. Specifically, it includes:

[0013] A reflector is a component of a plant growing rack. It is used to intercept light that is not absorbed by the plant after the initial exposure and reflect the light back to the plant. Its angle is specially set so that the reflected light can be focused on the plant.

[0014] Planting troughs, located inside the reflector, are used to fix the planted plants in place;

[0015] A liquid storage tank, which is a cavity formed by a plant planting trough and a reflector, is used to store a mixture of water and nutrient solution required for plant growth.

[0016] An irrigation device, installed on a plant growing rack, is used to deliver irrigation liquid to the planted plants, including:

[0017] The first liquid storage tank is located at one end of the plant growing rack and is used to store water for watering the plant.

[0018] The second nutrient solution tank is located at the other end of the plant growing rack and is used to store the nutrient solution for watering the plant.

[0019] The first infusion tube connects the storage tank and the first storage container, and is used to transport the liquid in the first storage container to the storage tank;

[0020] The second infusion tube connects the storage tank and the second storage container, and is used to transport the liquid in the second storage container to the storage tank.

[0021] By recycling light that has not been absorbed by the plant and then irradiating the plant again, the secondary use of light energy reduces the loss of light energy during artificial lighting and improves the energy utilization rate.

[0022] Furthermore, the LED lighting panel is closely attached to the upper liquid storage tank, the first infusion pipe, and the second infusion pipe, so that the LED panel can be cooled by water using the upper liquid storage tank, the first infusion pipe, and the second infusion pipe, thereby improving its heat dissipation capacity and preventing damage to the LED panel due to excessive temperature.

[0023] Furthermore, the portion of the reflector located above the plant planting trough is set in a standard elliptical shape or a standard parabolic shape, with its focal point being the position of the plant. This allows the light reflected by the reflector to fall on the plant more likely, promoting plant photosynthesis.

[0024] Furthermore, the reflector is made directly from reflective material or by covering any material with a reflective film, thus giving the reflector reflective capability.

[0025] Furthermore, a rough reflective film is attached to the upper side of the plant planting trough, which reflects the light that has passed through the plant back to the plant through diffuse reflection, thereby improving energy utilization.

[0026] Furthermore, a water pump is installed in the first liquid storage tank and a water pump is also installed in the second liquid storage tank to extract the liquid from each liquid storage tank and transport it to the liquid storage tank through the first liquid delivery pipe and the second liquid delivery pipe, respectively, so that the liquid in the liquid storage tank can be transferred to the liquid storage tank for plant use.

[0027] Furthermore, a one-way flow rate control valve is installed at the connection between the first infusion tube and the storage tank, and a one-way flow rate control valve is also installed at the connection between the second infusion tube and the storage tank. The flow rate control valve only allows liquid to flow in one direction, that is, it can only flow from each infusion tube into the storage tank, to avoid liquid backflow and contamination of the liquid in the storage tank. In addition, the flow rate control valve can control the liquid flow rate, so that the nutrient solution and water are automatically prepared in a reasonable ratio.

[0028] Furthermore, the first liquid storage tank located on each layer of the plant planting rack can be integrated into a first integrated liquid storage tank, and the second liquid storage tank located on each layer of the plant planting rack can be integrated into a second integrated liquid storage tank to achieve unified allocation and save energy.

[0029] Furthermore, both the first infusion tube and the second infusion tube are set close to the storage tank, and multiple outlet holes are provided at the connection points of the first infusion tube and the second infusion tube with the storage tank for outputting liquid to the storage tank.

[0030] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0031] 1. In view of the problem that some of the light emitted by the supplementary lighting source in the existing technology is not effectively utilized by the plants, resulting in energy waste, this utility model can effectively intercept and reflect the unabsorbed light to the plants by setting a reflector on the plant planting rack, thereby improving the utilization rate of light energy and reducing energy waste.

[0032] 2. In view of the problem of insufficient supplemental lighting on the sides and bottom of plants in the existing technology, this utility model realizes all-round supplemental lighting on the top, bottom and sides of plants by reflecting the side light through the reflector and the diffuse reflection of the bottom transmitted light through the rough reflective film on the upper surface of the plant planting trough, which effectively promotes photosynthesis.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] like Figures 1-2 As shown, the plant supplemental lighting stand provided by this utility model recovers and reuses light that has not been absorbed by the plant, allowing it to irradiate the plant again. This secondary use of light energy reduces light energy loss during artificial lighting and improves energy utilization. Specifically, it includes the following structure:

[0039] The light stand frame 1 is used to support the plant planting rack 3 and the LED lighting panel 2 to complete the tasks of crop planting and supplemental lighting;

[0040] LED lighting panel 2 is installed on the lamp holder frame 1 and is used to provide supplemental lighting for the plants planted on the lamp holder.

[0041] A planter 3 is mounted on the lamp holder frame 1, located on the same side of the lamp holder frame 1 as the LED lighting panel 2, and alternately mounted vertically on the lamp holder frame 1 for planting plants, such as... Figure 3 As shown, it specifically includes:

[0042] The reflector 31, a component of the plant growing rack 3, is used to intercept light that is not absorbed by the plant after the initial illumination and reflect the light back to the plant. The reflector 31 can be made directly of reflective material, or... Figure 4As shown, it is made of any material with an additional layer of reflective film, so that the reflector 31 has reflective ability and can reflect the light emitted by the LED lighting panel 2 above and shining on the side of the plant back to the plant.

[0043] The reflector 31 is specially angled so that the reflected light can be focused on the plant. Specifically, for example... Figure 4 As shown, the portion of the reflector 31 located above the plant planting trough 32 is set in a standard elliptical shape or a standard parabolic shape, with its focal point designed to be the typical growth position of the plant (not shown). In this way, the light emitted from the LED lighting panel 2 and illuminating the inner wall of the reflector 31 will be reflected parabolically and directed parallel to the plant or converge in the plant area, thereby improving the light energy utilization rate and promoting plant photosynthesis.

[0044] Planting trough 32 is set inside the reflector 31 and is used to fix the planted plants. The upper side of the planting trough 32 is covered with a rough reflective film, which reflects the light transmitted through the plant back to the planted plant through diffuse reflection, so as to improve the energy utilization rate.

[0045] The liquid storage tank 33 is a cavity formed by the plant planting trough 32 and the reflector 31, which is used to store a mixture of water and nutrient solution required for plant growth.

[0046] The bottom surface of each layer of the plant growing rack 3 is in close contact with the LED lighting panel 2 located below it. This arrangement allows the lower LED lighting panel 2 to make close contact with the bottom of the liquid storage tank 33 of the upper layer of the plant growing rack 3, as well as the first infusion pipe 43 and the second infusion pipe 44. Therefore, the heat generated by the LED lighting panel 2 during operation can be effectively absorbed by the liquid in the upper liquid storage tank 33 and the liquid in the infusion pipes, achieving water cooling. This not only improves the heat dissipation capacity of the LED panel and avoids damage caused by excessive temperature, but also extends the service life of the LED panel and even the entire device.

[0047] An irrigation device 4, installed on the plant planting rack 3, is used to deliver irrigation liquid to the planted plants, and includes:

[0048] The first liquid storage tank 41 is located at one end of the plant planting rack 3 and is used to store water for watering the plant.

[0049] The second liquid storage tank 42 is located at the other end of the plant planting rack 3 and is used to store nutrient solution for watering the plant.

[0050] The first infusion tube 43 connects the liquid storage tank 33 and the first liquid storage container 41, and is used to transport the liquid in the first liquid storage container 41 to the liquid storage tank 33.

[0051] The second infusion tube 44 connects the liquid storage tank 33 and the second liquid storage container 42, and is used to transport the liquid in the second liquid storage container 42 to the liquid storage tank 33.

[0052] A water pump is installed in the first liquid storage tank 41 and a water pump is also installed in the second liquid storage tank 42. The water pump is used to draw out the liquid from each liquid storage tank and transport it to the liquid storage tank 33 through the first liquid delivery pipe 43 and the second liquid delivery pipe 44 respectively. This allows the liquid in the liquid storage tank to be transferred to the liquid storage tank 33 for the plants to use. The setting of mixing water and nutrient solution only when in use also reduces the possibility of nutrient solution deterioration and retains the nutrients in the nutrient solution to a greater extent, so that the plant can absorb more nutrients.

[0053] A one-way flow rate control valve is installed at the connection between the first infusion pipe 43 and the storage tank 33, and a one-way flow rate control valve is also installed at the connection between the second infusion pipe 44 and the storage tank 33. The flow rate control valve only allows liquid to flow in one direction, that is, it can only flow from each infusion pipe into the storage tank 33, to avoid liquid backflow and contamination of the liquid in the storage tank. Furthermore, the opening degree or flow rate setting of the one-way flow rate control valve can be adjusted independently, so as to control the rate at which water and nutrient solution enter the storage tank 33 according to a preset ratio, and realize the proportional mixing of the two.

[0054] like Figure 1 The first liquid storage tank 41 located on each layer of the plant planting rack 3 shown can be integrated into a first integrated liquid storage tank, and the second liquid storage tank 42 located on each layer of the plant planting rack 3 can be integrated into a second integrated liquid storage tank, so as to unify the distribution and save energy.

[0055] Both the first infusion tube 43 and the second infusion tube 44 are closely attached to the liquid storage tank 33. Multiple liquid outlet holes 45 are provided at the connection points of the first infusion tube 43 and the second infusion tube 44 with the liquid storage tank 33 for outputting liquid to the liquid storage tank 33.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.
