Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to LED plant growth lights. Background Technology

[0002] LED plant grow lights are artificial light sources specifically designed for plant growth. Using light-emitting diode technology, they precisely control the spectrum of specific wavelengths such as red and blue light to provide plants with the light energy needed for photosynthesis in environments lacking natural light. Compared to traditional lighting fixtures, LED plant lights offer advantages such as high luminous efficiency, low energy consumption, long lifespan, low heat generation, and adjustable spectrum, making them widely used in greenhouse supplemental lighting, plant factories, home gardening, and agricultural research.

[0003] Existing plant grow lights, such as the Chinese application with application number 202321350612.4, entitled "An Energy-Saving Greenhouse LED Plant Supplemental Light," utilize a micro motor to rotate a rotating rod. This rotation, via a main bevel gear and an auxiliary bevel gear, causes the rotating shaft to rotate, which in turn drives a reel to rotate and wind up the traction rope. This, in turn, raises or lowers the supplemental light, thus achieving height adjustment and facilitating supplemental lighting for plants at different heights.

[0004] The existing technology has the following defects: In the above-mentioned plant grow lights, the grow lights only provide vertical light from top to bottom. The upper part of the plant, especially the top leaves, receives too much light, which can easily cause problems such as light burn and overheating at the top. The lower leaves and side branches of the plant are blocked by the top leaves, resulting in insufficient light and affecting their photosynthetic efficiency. It is not suitable for columnar or tall crops, so there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an LED plant growth light to solve the technical problem that existing supplemental lighting provides vertical light, resulting in uneven light distribution to the leaves and failing to meet the growth needs of upright or tall crops.

[0006] To achieve this objective, the present invention adopts the following technical solution: The LED plant growth light includes a mounting frame, an adjustment component, a lamp holder, and LED lights. The mounting frame is fixed to the top of a greenhouse or a support component. The lamp holder is detachable and installed on the mounting frame. Viewed horizontally, the lamp holder is arc-shaped and is a flexible lamp holder. The adjustment component is located on the mounting frame and is used to adjust the opening angle of the lamp holder. The LED lights are evenly distributed on the bottom surface of the lamp holder.

[0007] Optionally, the LED plant growth light also includes a sliding assembly. The mounting bracket is provided with a slide rail, and the slide rail is provided with a rack. The sliding assembly includes a mounting base, a gear, and a motor. The motor is fixed on the mounting base and is used to drive the gear to rotate. The gear meshes with the rack. The lamp holder is fixed on the mounting base.

[0008] Optionally, the adjustment assembly includes a crossbar and a telescopic rod. The crossbar is fixed to the mounting base, and the telescopic rod is disposed at both ends of the crossbar. The telescopic ends of the telescopic rod are fixed to both sides of the lamp holder.

[0009] Optionally, the top surface of the lamp holder is provided with multiple sets of mounting blocks, the telescopic rod is rotatably mounted on the crossbar, and the telescopic end of the telescopic rod is fixed to the mounting block.

[0010] Optionally, the telescopic end of the telescopic rod is provided with a first magnetic plate, and the mounting block is provided with a second magnetic plate, wherein the magnetic poles of the first magnetic plate and the second magnetic plate are opposite.

[0011] Optionally, the lamp holder is provided with a mounting rod on top, and the mounting rod is threadedly connected to the mounting base.

[0012] Optionally, the mounting bracket is further provided with a conductive groove, the lamp holder is provided with a guide rod, the end of the guide rod is provided with a conductive sheet, and the conductive sheet is electrically connected to the conductive groove.

[0013] Optionally, a heat sink is provided on the top of the lamp holder.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention features an arc-shaped lamp holder, which allows the LED light source to diffuse in an arc shape, resulting in more uniform illumination of leaves at different heights. This prevents top leaves from blocking bottom leaves and meets the light requirements of columnar or tall-stemmed crops. At the same time, the opening angle of the lamp holder can be adjusted by adjusting the component to meet the light requirements of crops of different shapes, further improving the growth rate of plants.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Figure 6 for Figure 5 Enlarged view of point D in the middle.

[0023] The LED plant growth light provided in this embodiment is applied to plant cultivation, seedling raising, and supplemental lighting scenarios under artificial light environments. In this embodiment, by improving the structure of the plant growth light, the uniformity of light exposure on crop leaves is improved, and the growth needs of crops of different forms are met.

[0024] Please see Figures 1-6 The LED plant growth light provided in this embodiment includes a mounting frame 10, an adjustment component 30, a lamp holder 40, and LED lights 50. The mounting frame 10 is fixed to the top of the greenhouse or a support component. The lamp holder 40 is detachably mounted on the mounting frame 10. From a horizontal perspective, the lamp holder 40 is arc-shaped and is an elastic lamp holder 40. The adjustment component 30 is disposed on the mounting frame 10 and is used to adjust the opening angle of the lamp holder 40. The LED lights 50 are evenly distributed on the bottom surface of the lamp holder 40. Specifically, the mounting frame 10 is the mounting base of the entire light and can be fixedly set on the top of the greenhouse, indoor planting rack, or other components with structural support capabilities. Its structural form can be frame type, guide rail type, etc., and can be flexibly selected according to the installation environment. The above structures are well known to those skilled in the art, so they will not be described in detail in this embodiment. The lamp holder 40 is the main light-emitting carrier of this device and is detachably connected to the mounting frame 10 for easy installation, replacement, or adjustment.

[0025] The lamp holder 40 has an arc-shaped structure when viewed horizontally, with its bottom surface forming an embracing arc structure. The lamp holder 40 also possesses a certain degree of elasticity, allowing it to expand or contract at a certain angle under external force without permanent deformation. For example, high-strength elastic metal materials or composite elastic engineering plastics can be used as the lamp holder 40. LEDs 50 are evenly distributed on the bottom surface of the lamp holder 40. The selected LEDs 50 can be single-band light sources (such as red or blue light), multi-band combined LED beads, or full-spectrum LED modules that meet the needs of plants at different growth stages.

[0026] The arc-shaped lamp holder 40 allows the light emitted by the LED lamp 50 to diffuse downwards at a certain angle. Compared to the vertical downward illumination of traditional linear lamps, this structure effectively avoids the problem of top leaves blocking bottom leaves caused by light only hitting the ground vertically. This is especially suitable for the planting environment of tall crops such as corn, tomatoes, and peppers. By distributing the light angle from the top to the side, all leaf levels from the top to the base of the plant can receive light evenly, improving the overall photosynthetic efficiency and thus promoting balanced plant growth.

[0027] An adjustment component 30 is mounted on the mounting frame 10 and is used to adjust the opening angle of the lamp holder 40. The adjustment component 30 is connected to both sides of the lamp holder 40. Through its driving or telescopic action, the arc structure of the lamp holder 40 can be opened and closed within a certain range, thereby achieving dynamic adjustment of the illumination angle. When the crop is in the seedling stage, the angle of the lamp holder 40 can be narrowed by adjusting the component 30 to increase the concentration of light intensity. After the plant grows taller and the leaves unfold, the angle of the lamp holder 40 can be widened to expand the illumination range, so as to adapt to the light needs of different crop types and growth stages, and further improve the overall growth rate and light energy utilization efficiency of the plant.

[0028] Please see Figure 1 and Figure 2Furthermore, the LED plant growth light also includes a sliding assembly 20. A slide rail 11 is provided on the mounting frame 10, and a rack portion 12 is provided inside the slide rail 11. The sliding assembly 20 includes a mounting base 210, a gear portion 220, and a motor 230. The motor 230 is fixed to the mounting base 210 and is used to drive the gear portion 220 to rotate. The gear portion 220 meshes with the rack portion 12. The lamp holder 40 is fixed to the mounting base 210. Specifically, the sliding assembly 20 is disposed on the mounting frame 10 and is used to drive the lamp holder 40 to move along a set trajectory. The mounting frame 10 is provided with a slide rail 11, the cross-section of which can be "T"-shaped or dovetail-shaped. A rack portion 12 aligned with its length direction is provided inside the slide rail 11 for meshing with the gear portion 220. The sliding assembly 20 includes a mounting base 210, a gear section 220, and a motor 230. The motor 230 is fixed to the mounting base 210 and drives the gear section 220 to rotate. The gear section 220 meshes with the rack section 12 inside the slide rail 11, thereby driving the mounting base 210 to make linear sliding movements along the slide rail 11. The lamp holder 40 is fixed to the mounting base 210, thereby driving the lamp holder 40 to adjust its position. More specifically, multiple sliding assemblies 20 and multiple lamp holders 40 can be installed on the slide rail 11 to achieve group lighting of a large planting area, avoiding the shortcomings of traditional fixed lamps that have limited illumination range and cannot cover corner plants.

[0029] Please see Figure 1 and Figure 3 Furthermore, the adjustment component 30 includes a crossbar 310 and a telescopic rod 320. The crossbar 310 is fixed to the mounting base 210, and the telescopic rod 320 is located at both ends of the crossbar 310. The telescopic ends of the telescopic rod 320 are fixed to both sides of the lamp holder 40. Specifically, the telescopic rod 320 is used to drive the opening and closing angle of the lamp holder 40 to meet the requirements of light distribution angle in different application scenarios. More specifically, the structure of the telescopic rod 320 can adopt a threaded telescopic type, a gas spring type, or an electric sliding rod type, etc., to realize the adjustment of the opening and closing angle of the lamp holder 40, improve the illumination coverage of the LED light source, and facilitate precise control of light intensity and angle according to the different requirements of plants at different stages (such as seedling stage, flowering stage, and fruiting stage), thereby improving light utilization efficiency and plant growth quality.

[0030] Please see Figure 1 and Figure 3 Furthermore, the top surface of the lamp holder 40 is provided with multiple sets of mounting blocks 41, and the telescopic rod 320 is rotatably mounted on the crossbar 310, with the telescopic end of the telescopic rod 320 fixed to the mounting block 41. Specifically, the lamp holder 40 is provided with different mounting blocks 41, so that the telescopic end of the telescopic rod 320 can be fixed to the mounting block 41 at different positions respectively. The curvature of the lamp holder 40 can be adjusted according to the growth form of different plants to increase the light intensity of the plants and reduce the shading of the top leaves from the bottom leaves.

[0031] Please see Figure 1 and Figure 3 Furthermore, the telescopic end of the telescopic rod 320 is provided with a first magnetic plate 321, and the mounting block 41 is provided with a second magnetic plate 42. The magnetic poles of the first magnetic plate 321 and the second magnetic plate 42 are opposite. Specifically, the telescopic end of the telescopic rod 320 is provided with a first magnetic plate 321, and the mounting block 41 is provided with a matching second magnetic plate 42. The two have opposite magnetic poles and will generate a magnetic force that attracts each other when they are close together. This allows the telescopic end of the telescopic rod 320 to fit more quickly and accurately with the mounting block 41 and maintain relative stability, improving the convenience and accuracy of the adjustment operation.

[0032] Please see Figure 1 and Figure 4 Furthermore, the lamp holder 40 is provided with a mounting rod 43 on its top, and the mounting rod 43 is threadedly connected to the mounting base 210. Specifically, the threaded connection between the mounting rod 43 and the mounting base 210 allows the lamp holder 40 to be easily removed from or reinstalled from the mounting base 210 when it needs to be replaced, repaired, or adjusted.

[0033] Please see Figure 5 and Figure 6 Furthermore, the mounting bracket 10 is also provided with a conductive groove 13, and the lamp holder 40 is provided with a guide rod 44. A conductive piece 45 is provided at the end of the guide rod 44, and the conductive piece 45 is electrically connected to the conductive groove 13. Specifically, the conductive piece 45 is electrically connected to the conductive groove 13, which realizes the continuous power supply of the conductive groove 13 to the LED lamp 50 during the movement of the sliding assembly 20, ensuring that the LED lamp 50 can continuously obtain stable power during the sliding process.

[0034] Please see Figure 1 and Figure 4 Furthermore, a heat sink 60 is provided on the top of the lamp holder 40. Specifically, the heat sink 60 improves the heat exchange efficiency of the LED lamp 50, keeps the operating temperature of the LED lamp 50 within a safe and stable range, improves the lifespan and stability of the lamp, reduces maintenance frequency and replacement costs, and meets the long-term continuous lighting needs of greenhouses and other similar facilities.
