Description

Technical Field

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

[0002] LED lights for promoting plant growth are highly efficient artificial lighting devices that can simulate different wavelengths of natural light to meet the light requirements of plants at different growth stages. These lights typically emit a specific combination of red and blue light to promote photosynthesis, thereby enhancing plant growth, flowering, and fruiting. Due to their low energy consumption, long lifespan, and low heat generation, LED lights are widely used in modern agriculture and indoor horticulture.

[0003] Existing plant growth promoting lamps, such as the Chinese application with application number 202210622057.X, entitled "A Plant Growth Supplemental Light," include: a rear cover, a first end cover, a second end cover, a lamp panel, a dimming controller, and a start / stop switch. A germicidal lamp area is formed by evenly distributing second lamps in the center of the lamp panel, and supplemental lighting lamp areas are formed by evenly distributing first lamps on both sides of the germicidal lamp area. The dimming controller adjusts the output power of each first lamp to emit light of different wavelengths and intensities, thus meeting the light requirements of different plants at different growth stages and achieving the best supplemental lighting effect.

[0004] The existing technology has the following defects: In the above-mentioned plant growth supplement light, the first and second lamp beads are arranged to form a lamp panel, and the lamp beads are adjusted by the controller so that the supplement light can meet the light needs of different plants at different growth stages. However, due to the planar arrangement of the lamp beads, it is easy to cause high light intensity at the top of the plant and insufficient light intensity at the bottom leaves, resulting in uneven light acquisition by the plant. At the same time, it is easy to cause some leaves to be in the shade for a long time and not receive effective light, which affects their normal growth. Therefore, there is room for improvement.

[0030] The LED light fixture for promoting plant growth provided in this embodiment is applied to scenarios of rapid seedling cultivation or plant cultivation. In this embodiment, the structure of the LED light fixture is improved so that the shape of the LED light fixture can be freely adjusted, thereby increasing the light coverage area per unit area.

[0031] Please see Figures 1-6 The LED light fixture for promoting plant growth provided in this embodiment includes a support frame 1, a mounting frame 2, and an LED assembly 3. The support frame 1 is fixed to the ground or other support platform, the mounting frame 2 is rotatably mounted on the support frame 1, and the LED assembly 3 is disposed on the mounting frame 2. The mounting frame 2 includes multiple sets of second frames 22, and a set of first frames 21 is connected between two adjacent sets of second frames 22. The second frames 22 and the first frames 21 are rotatably engaged, and the LED assembly 3 is disposed on the second frames 22.

[0032] Specifically, select a suitable location for plant growth and fix the support frame 1 to the ground or other support platform; rotatably install the mounting bracket 2 onto the support frame 1, ensuring it can rotate freely; install the LED assembly 3 onto the second frame 22, ensuring the LED assembly 3 is securely installed and well connected; insert the power plug of the lamp into the power socket and check if the switch operates normally; regularly observe the plant's growth status, check if the light is sufficient, and adjust the lamp shape according to the plant's growth changes to ensure the optimal light angle for the plant.

[0033] The arrangement of the first frame 21 and the second frame 22 enables the adjustment of the lamp shape. By adjusting the shape and angle of the lamp, it can be ensured that the light source shines directly on all parts of the plant, especially the top and bottom leaves of tall plants, improving the uniformity of light, promoting the efficiency of photosynthesis, and thus increasing the growth rate of the plant. At the same time, by flexibly adjusting the shape of the lamp, the shadows produced by some plants when the light is uneven can be reduced, ensuring that most plants can obtain sufficient light.

[0034] Please see Figure 3 and Figure 4 Plants at different growth stages have different requirements for red and blue light. In the seedling stage, plants typically need more blue light to promote stem and leaf growth, while during flowering and fruiting, they require more red light. Based on this, in one embodiment, the LED assembly 3 includes a red LED 31, a blue LED 32, and a rotating shaft 33. The red LED 31 and blue LED 32 are adhered face-to-face to the rotating shaft 33, which is rotatably mounted on the second frame 22 along a first direction. By rotating the rotating shaft 33 to adjust the ratio of red and blue light, the photosynthetic efficiency can be optimized according to the plant's life cycle, improving photosynthetic yield and biological quality. The rotating shaft 33, mounted on the second frame 22, ensures that plants in different locations receive a suitable light ratio.

[0035] Please see Figure 3 , Figure 4 and Figure 5 Furthermore, the inner walls of the second frame 22 are respectively provided with mounting grooves 4 and snap-fit ​​grooves 5 at both ends. One end of the rotating shaft 33 is rotatably mounted in the mounting groove 4, and the other end of the rotating shaft 33 is provided with a snap-fit ​​member 6. The snap-fit ​​member 6 is rotatably engaged with the snap-fit ​​groove 5. A gripping part 7 is coaxially provided on the snap-fit ​​member 6, and the gripping part 7 is rotatably mounted on the outside of the second frame 22. The mounting groove 4 provides a stable rotation reference for the rotating shaft 33, which can effectively position one end of the rotating shaft 33, keep it in the correct position, and allow it to rotate smoothly. The snap-fit ​​groove 5 ensures that the rotating shaft 33 will not easily fall off. The gripping part 7 is provided as an operating handle for the user, allowing the user to easily hold and rotate the rotating shaft 33 for light adjustment. Specifically, the snap-fit ​​member 6 can be set as a sphere, and the snap-fit ​​groove 5 matches the shape of the snap-fit ​​member 6.

[0036] Please see Figure 3 and Figure 4 Furthermore, the inner bottom surface of the second frame 22 is provided with several sets of lamp holders 8. Red LED beads 31 are connected to a first electric ring 9, and blue LED beads 32 are connected to a second electric ring 10. The vertical cross-section of the first electric ring 9 and the second electric ring 10 is semi-circular. The first electric ring 9 and the second electric ring 10 are fixed to the rotating shaft 33, and the first electric ring 9 and the second electric ring 10 are shaped to fit the lamp holders 8 and are electrically connected. Specifically, when the first electric ring 9 contacts the lamp holder 8, the first electric ring 9 is turned on, causing the red LED bead 31 to emit light; when the second electric ring 10 contacts the lamp holder 8, the second electric ring 10 is turned on, causing the blue LED bead 32 to emit light; when the first electric ring 9 and the second electric ring 10 are in contact with the lamp holder 8 at the same time, the red LED bead 31 and the blue LED bead 32 emit light simultaneously.

[0037] Furthermore, the second frame 22 has an angle scale line on one end where the grip part 7 is rotatably mounted. The scale line displays the proportion of red light illumination, and the user can calculate the red-blue light illumination ratio based on the proportion of red light illumination, ensuring that plants at different growth stages receive appropriate light and improving the accuracy of red-blue light ratio adjustment.

[0038] Please see Figure 1 Furthermore, the support frame 1 includes a main frame 11 and a cantilever 12. The main frame 11 is fixed to the ground or other support platform, and the cantilever 12 is rotatably mounted on the main frame 11. The second frame 22 is rotatably mounted on the cantilever 12. The cantilever 12 and the main frame 11 rotate to cooperate, expanding the shape adjustment range of the lamp to meet the lighting needs of different plants and growth stages.

[0039] Furthermore, a solar panel is installed on the top surface of the second frame 22. The solar panel can convert sunlight into electrical energy, which increases the power of the LEDs and reduces the user's electricity bill.

[0040] Please see Figure 6 Furthermore, the first frame 21 includes an end plate 211 and mounting posts 212. Two sets of mounting posts 212 are arranged along the first direction, and the end plates 211 are fixed to both ends of the mounting posts 212. The second frame 22 has two sets of through slots 13 arranged along the first direction. The mounting posts 212 are inserted into the through slots 13 and are interference-fitted. The mounting posts 212 are inserted into and fixed to the end plates 211. The interference fit ensures that the lamp will not easily deform or shift due to shaking or collision during use, thereby maintaining the stability of the working state of the mounting frame 2.

[0041] In summary, the LED light fixture for promoting plant growth provided in this embodiment improves the uniformity of light illumination for plant supplemental lighting and promotes the efficiency of plant photosynthesis.

[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
