Description

Technical Field

[0001] This invention belongs to the technical field of plant supplemental lighting devices, specifically, it relates to a supplemental lighting device for promoting plant growth. Background Technology

[0002] Plant grow lights effectively promote photosynthesis in plants by simulating key spectra in sunlight, enabling them to grow healthily indoors or in low-light environments. With technological advancements and cost reductions, this technology, originally found primarily in professional greenhouses, is gradually entering ordinary households with its compact design and convenient usage, becoming a powerful tool for urban gardening enthusiasts to improve the growth quality of potted plants and flowers.

[0003] However, existing plant grow lights mainly use a top-down illumination method, which inevitably leads to uneven lighting. This is mainly reflected in the fact that the dense upper leaves block some of the light like an umbrella, resulting in less light for the lower leaves. This causes the top leaves to grow larger and darker green, while the bottom leaves are affected by insufficient light, often appearing smaller and paler in color. Summary of the Invention

[0004] This invention provides a supplemental lighting device to promote plant growth. By adding a lamp body that can revolve around the plant on the side, it solves the problem mentioned in the background art, namely: insufficient light for the bottom leaves, resulting in smaller leaf volume.

[0005] To solve the above-mentioned technical problems, a supplementary lighting device for promoting plant growth is provided, including a base, an arc-shaped frame connected to the base via a support rod, a lamp housing fixedly connected to the top of the arc-shaped frame, and a disc-shaped cover rotatably connected to the lower end of the lamp housing. The outer wall of the disc-shaped cover is fixedly connected to a downwardly curved arc-shaped tube. A main lamp body and an auxiliary lamp body are respectively installed on the lower surface of the disc-shaped cover and on the arc-shaped tube. The illumination direction of the auxiliary lamp body is towards the axis of the arc-shaped tube. Secondly, it also includes a rotating part, which is disposed on the lamp housing. The rotating part is used to drive the disc-shaped cover to rotate around its axis, and at the same time drive the arc-shaped tube to revolve around the axis of the disc-shaped cover.

[0006] The rotating part includes a vertical tube fixedly connected to the top of the disc-shaped cover. A drive motor is fixedly mounted on the top of the lamp housing via a mounting bracket. A drive shaft is fixedly mounted on the output end of the drive motor. A transmission shaft is rotatably mounted on the mounting bracket. A ring gear is fixedly mounted on the inner wall of the vertical tube. A transmission gear meshing with the ring gear is fixedly mounted on the transmission shaft. A drive gear meshing with the transmission gear is fixedly mounted on the drive shaft, which is used to realize that the light revolves around the plant.

[0007] Secondly, an arc-shaped outer cover is fixedly connected to the disc-shaped cover, and the arc-shaped outer edge of the arc-shaped tube is fitted inside the arc-shaped outer cover. The arc-shaped outer cover is provided with a swinging part that drives the arc-shaped tube to bend intermittently in the axial direction. The arc-shaped tube is elastic, so that the illumination angle of the lamp tube is variable rather than fixed.

[0008] Furthermore, two conductive rings are fixedly installed on the outer wall of the vertical tube, and two wires are fixedly connected to the lamp housing. Each of the two wires is fixedly connected to a brush, and the two sets of brushes rest on the two conductive rings respectively to ensure that the rotating main lamp body and the auxiliary lamp body can be powered normally.

[0009] Therefore, by making the light revolve around the plant, most of the plant's leaves can receive more adequate supplemental lighting.

[0010] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. This invention drives a motor to rotate the vertical tube and the disc-shaped cover. The disc-shaped cover drives the main lamp body and the arc-shaped tube at the bottom to rotate. The arc-shaped tube drives the auxiliary lamp body to revolve around the plant. The light range of the main lamp body will be wider and more uniform, while the auxiliary lamp body can more comprehensively and effectively irradiate the sides and lower leaves of the plant. This can significantly improve the irradiation effect of the supplementary lighting device on the plant, making most of the plant's leaves more uniform and full.

[0011] 2. The invention also creates a disturbance in the air around the plant through the revolving arc tube 8. Some leaves will flutter under the disturbance, which can improve the supplemental lighting effect, simulate a breeze blowing on the plant surface to make the plant branches more stable, and improve the air circulation to facilitate the plant's photosynthesis with carbon dioxide.

[0012] 3. The present invention uses a reciprocating sliding arc plate to make the arc tube bend back and forth, which in turn makes the auxiliary lamp body illuminate the plant leaves at different illumination angles. Combined with the continuously rotating arc tube, the auxiliary lamp body will illuminate the plant leaves more evenly, further improving the effect of supplemental lighting for plants.

[0013] 4. This invention uses an active shaft to drive the fan blades to rotate inside the vertical tube, which in turn continuously blows air into the disc-shaped cover. Part of the airflow inside the disc-shaped cover is discharged from the main exhaust port to the top of the plant, while another part of the airflow enters the arc-shaped tube and is finally discharged from the secondary exhaust port to the side of the plant. On the one hand, this can achieve active heat dissipation for the main and secondary lamp bodies, thereby improving their service life. On the other hand, the airflow blows onto the surface of the plant, simulating an outdoor windy environment. The plant's branches become more stable due to the wind, and the better airflow further promotes the photosynthesis of carbon dioxide by the plant.

[0014] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] Example 1: Refer to Figures 1-3 A supplemental lighting device for promoting plant growth includes a base 1 for supporting the entire device. The base 1 is plate-shaped, and an arc-shaped frame 3 is connected to the base 1 via a support rod 2. The support rod 2 can be replaced by a telescopic rod to adjust the distance for supplemental lighting on the plants. A lamp housing 4 is fixedly connected to the top of the arc-shaped frame 3. The device also includes a disc-shaped cover 6, which is rotatably connected to the lower end of the lamp housing 4. A downwardly curved arc-shaped tube 8 is fixedly connected to the outer wall of the disc-shaped cover 6. A main lamp body 7 and an auxiliary lamp body 9 are respectively installed on the lower surface of the disc-shaped cover 6 and the arc-shaped tube 8. Both the main lamp body 7 and the auxiliary lamp body 9 are lamp panels or lamp beads used for supplemental lighting on plants. The illumination direction of the auxiliary lamp body 9 is towards the axis of the arc-shaped tube 8. The device also includes a rotating part, which is disposed on the lamp housing 4. The rotating part is used to drive the disc-shaped cover 6 to rotate around its axis and simultaneously drive the arc-shaped tube 8 to revolve around the axis of the disc-shaped cover 6.

[0019] Specifically, move the base 1 until the disc-shaped cover 6 with the main light body 7 is directly above the potted plant. Then turn on the main light body 7 and the auxiliary light body 9. The main light body 7 will illuminate the top of the plant, and the auxiliary light body 9 will illuminate one side of the plant. The rotating part can drive the disc-shaped cover 6 to rotate, which in turn drives the main light body 7 and the arc tube 8 at the bottom to rotate. The arc tube 8 will drive the auxiliary light body 9 to revolve around the plant. The light range of the main light body 7 will be wider and more uniform, while the auxiliary light body 9 can more comprehensively and effectively illuminate the sides and lower leaves of the plant. This can significantly improve the illumination effect of the supplemental lighting device on the plant, making most of the plant's leaves more uniform and full.

[0020] Example 2: Refer to Figure 3 and Figure 4 A supplemental lighting device for promoting plant growth, which is basically the same as in Example 1, but further includes the following: The aforementioned rotating part includes a vertical tube 5 fixedly connected to the top of the disc-shaped cover 6. The bottom of the vertical tube 5 is connected to the disc-shaped cover 6. A drive motor 11 is fixedly mounted on the top of the lamp housing 4 via a mounting bracket 18. A drive shaft 12 is fixedly mounted on the output end of the drive motor 11. A transmission shaft 13 is rotatably mounted on the mounting bracket 18. A ring gear 16 is fixedly mounted on the inner wall of the vertical tube 5. A transmission gear 15 that meshes with the ring gear 16 is fixedly mounted on the transmission shaft 13. A drive gear 14 that meshes with the transmission gear 15 is fixedly mounted on the drive shaft 12.

[0021] Specifically, during use, when the drive motor 11 is started, the drive motor 11 will drive the drive gear 14 to rotate through the drive shaft 12. The drive gear 14 will drive the ring gear 16 to rotate through the transmission gear 15. The ring gear 16 will drive the vertical tube 5 and the disc-shaped cover 6 to rotate. The disc-shaped cover 6 will drive the main lamp body 7 and the arc-shaped tube 8 at the bottom to rotate. The arc-shaped tube 8 will drive the auxiliary lamp body 9 to revolve around the plant. The light range of the main lamp body 7 will be wider and more uniform, while the auxiliary lamp body 9 can more comprehensively and effectively illuminate the sides and lower leaves of the plant.

[0022] like Figure 9 As shown, two conductive rings 36 for power supply are fixedly installed on the outer wall of the above-mentioned vertical tube 5. The positive and negative poles of the main lamp body 7 and the auxiliary lamp body 9 are connected to the two conductive rings 36 respectively through wires. Two wires 35 are fixedly connected to the lamp housing 4. Each of the two wires 35 is fixedly connected to a brush 34. The two sets of brushes 34 are respectively pressed against the two conductive rings 36. The ends of the two wires 35 are connected to plugs for plugging into sockets.

[0023] Specifically, when the vertical tube 5 rotates, the brush 34 will always be in contact with the conductive ring 36, so that the main lamp body 7 and the auxiliary lamp body 9 can maintain connection with the external power supply.

[0024] like Figure 3 and Figure 6 As shown, the bottom of the mounting bracket 18 is fixedly connected to a device frame 19 extending into the vertical tube 5. Both sides of the device frame 19 are provided with mounting grooves 20, and each of the two mounting grooves 20 is equipped with a filter screen 21 for filtering dust.

[0025] Specifically, during use, filter 21 can reduce dust entering the disc-shaped cover 6 and the arc-shaped tube 8.

[0026] Example 3: Reference Figures 3-5 A supplemental lighting device for promoting plant growth, which is basically the same as in Example 2, but further includes the following: An arc-shaped outer cover 10 is fixedly connected to the aforementioned disc-shaped cover 6. The lower end of the arc-shaped outer cover 10 is provided with a slot. The arc-shaped outer edge of the arc-shaped tube 8 is fitted inside the arc-shaped outer cover 10. The arc-shaped outer cover 10 is provided with a swinging part that drives the arc-shaped tube 8 to bend intermittently in the axial direction. The arc-shaped tube 8 is elastic and can be bent under the action of external force. The swinging part includes an arc-shaped slide rail 24 fixedly installed inside the arc-shaped outer cover 10. An arc-shaped plate 25 is slidably installed on the arc-shaped slide rail 24. A top block 26 is fixedly connected to the lower end of the arc-shaped plate 25. A trapezoidal block 28 corresponding to the top block 26 is fixedly connected to the outer wall of the arc-shaped tube 8. A return spring 27 is installed between the arc-shaped plate 25 and the inner bottom of the arc-shaped outer cover 10. The top of the arc-shaped outer cover 10 is provided with a reciprocating part that drives the arc-shaped plate 25 to slide back and forth on the arc-shaped slide rail 24.

[0027] Specifically, during use, the reciprocating part drives the arc plate 25 to slide back and forth on the arc slide rail 24, and drives the top block 26 to intermittently push against the inclined surface of the trapezoidal block 28. When the top block 26 pushes against the trapezoidal block 28, the lower end of the arc tube 8 will bend towards the plant under the pressure of the top block 28. When the top block 26 moves away from the trapezoidal block 28, the arc tube 8 will bend back to its original position under its own elastic force. Thus, the reciprocating arc plate 25 will cause the arc tube 8 to bend back and forth, which will cause the auxiliary lamp body 9 to irradiate the plant leaves at different irradiation angles. With the continuous revolution of the arc tube 8, the auxiliary lamp body 9 will irradiate the plant leaves more evenly, further improving the effect of supplemental lighting for the plant.

[0028] like Figure 7 and Figure 8 As shown, the reciprocating part includes a short shaft 22 rotatably connected to the top of the inner side of the arc-shaped outer cover 10. A turntable 23 is fixedly installed at the lower end of the short shaft 22. A pull rope 29 is rotatably connected to one end of the arc-shaped plate 25 near the turntable 23. The other end of the pull rope 29 is eccentrically rotatably connected to the end face of the turntable 23. A driven gear 33 is fixedly installed at the top of the short shaft 22. A fixed gear 32 that meshes with the driven gear 33 is fixedly installed at the top of the inner side of the lamp housing 4.

[0029] Specifically, during the rotation of the disc-shaped cover 6, the arc-shaped outer cover 10 and the driven gear 33 will also rotate synchronously. The driven gear 33 will roll around the fixed gear 32. The driven gear 33 will drive the turntable 23 to rotate through the short shaft 22. The turntable 23 will intermittently pull the arc plate 25 through the pull rope 29. When the arc plate 25 is pulled, it will slide towards the turntable 23 on the arc-shaped slide rail 24. When it is not pulled, the return spring 27 will pull it to slide back to its original position. Thus, the continuously rotating turntable 23 will drive the arc plate 25 to slide back and forth on the arc-shaped slide rail 24, thereby realizing the driving work of the arc plate 25.

[0030] In another embodiment, when the arc-shaped tube 8 is close to the plant's leaves, the revolving arc-shaped tube 8 will also create a disturbance in the air around the plant. Some leaves will flutter under the disturbance, which can improve the supplementary lighting effect, simulate a breeze blowing on the plant surface, make the plant's branches more stable, and improve the airflow, which is conducive to the plant's photosynthesis with carbon dioxide.

[0031] Example 4: Reference Figure 3 , Figure 5 as well as Figure 6 A supplemental lighting device to promote plant growth, which is basically the same as in Example 3, but further includes the following: The outer wall of the aforementioned drive shaft 12 is fixedly installed with fan blades 17 located inside the vertical tube 5. The bottom of the disc-shaped cover 6 is provided with a main exhaust port 30 close to the main lamp body 7. The arc-shaped tube 8 is provided with a secondary exhaust port 31 facing its axis, and the secondary exhaust port 31 is close to the secondary lamp body 9. In order to make the exhaust volume of the secondary exhaust port 31 similar to that of the main exhaust port 30, the diameter of the main exhaust port 30 can be set to be smaller than the diameter of the secondary exhaust port 31. At the same time, the diameter of the secondary exhaust port 31 on the arc-shaped tube 8 can be set to be smaller the closer it is to the disc-shaped cover 6.

[0032] Specifically, during the rotation of the drive shaft 12, the drive shaft 12 also drives the fan blades 17 to rotate inside the vertical tube 5. The vertical tube 5 continuously blows air into the disc-shaped cover 6. Part of the airflow inside the disc-shaped cover 6 is discharged from the main exhaust port 30 to the top of the plant, while another part of the airflow enters the arc-shaped tube 8 and is finally discharged from the secondary exhaust port 31 to the side of the plant. On the one hand, this can realize the active heat dissipation of the main lamp body 7 and the secondary lamp body 9, thereby improving the service life of the main lamp body 7 and the secondary lamp body 9. On the other hand, the airflow blows onto the surface of the plant, making the plant simulate an outdoor windy environment. The branches of the plant become more stable due to the wind, and the airflow is better, which further promotes the photosynthesis of carbon dioxide by the plant. The reciprocating curved arc-shaped tube 8 will cause the wind force and angle to change continuously, which will make the wind more similar to the outdoor natural wind, further improving the plant's growth effect.

[0033] A temperature sensor is fixedly installed inside the arc-shaped outer cover 10, and the temperature sensor is connected to the drive motor 11 through a controller. When the temperature inside the arc-shaped outer cover 10 is higher than 35 degrees Celsius, the temperature sensor controls the output shaft of the drive motor 11 to reverse through the controller.

[0034] Specifically, when the temperature detected inside the arc-shaped outer cover 10 is higher than 35 degrees Celsius, the temperature sensor will cause the drive motor 11 to drive the fan blades 17 to reverse. As a result, the arc-shaped tube 8 and the disc-shaped cover 6 will draw in air through the main exhaust port 30 and the auxiliary exhaust port 31 at the bottom, instead of blowing hot air toward the plant. This can prevent excessively high temperatures from damaging the plant.

[0035] like Figure 1 As shown, multiple sets of the aforementioned main lamp bodies 7 are arranged circumferentially on the bottom of the disc-shaped cover 6, and the main exhaust port 30 is located between two main lamp bodies 7 at the specified position. Figure 5 As shown, the auxiliary exhaust port 31 is arranged around the auxiliary lamp body 9; thus, the heat dissipation efficiency of the main lamp body 7 and the auxiliary lamp body 9 can be improved.

[0036] It was also found that in cold weather, the hot air discharged from the main exhaust port 30 and the secondary exhaust port 31 can warm up the surrounding environment of the plant, thus providing a frost protection effect for the plant in the low temperature environment.

[0037] In use, the base 1 is moved until the disc-shaped cover 6 with the main lamp body 7 is directly above the potted plant. Then, the main lamp body 7, the auxiliary lamp body 9, and the drive motor 11 are turned on. The main lamp body 7 illuminates the top of the plant, and the auxiliary lamp body 9 illuminates one side of the plant. The drive motor 11 drives the drive gear 14 to rotate via the drive shaft 12. The drive gear 14 drives the ring gear 16 to rotate via the transmission gear 15. The ring gear 16 drives the vertical tube 5 and the disc-shaped cover 6 to rotate. The disc-shaped cover 6 drives the main lamp body 7 and the arc-shaped tube 8 at the bottom to rotate. The arc-shaped tube 8 drives the auxiliary lamp body 9 to revolve around the plant. The light range of the main lamp body 7 becomes wider and more uniform, while the auxiliary lamp body 9 can more comprehensively and effectively illuminate the sides and lower leaves of the plant. This significantly improves the illumination effect of the supplementary lighting device on the plant, making most of the plant's leaves more uniform and full.

[0038] During the rotation of the disc-shaped cover 6, it also drives the arc-shaped outer cover 10 and the driven gear 33 to rotate synchronously. The driven gear 33 rolls around the fixed gear 32, and the driven gear 33 drives the turntable 23 to rotate through the short shaft 22. The turntable 23 intermittently pulls the arc-shaped plate 25 through the pull rope 29. When the arc-shaped plate 25 is pulled, it slides closer to the turntable 23 on the arc-shaped slide rail 24. When it is not pulled, the return spring 27 pulls it to slide back to its original position. Thus, the continuously rotating turntable 23 drives the arc-shaped plate 25 to slide back and forth on the arc-shaped slide rail 24, and also... The moving top block 26 intermittently pushes against the inclined surface of the trapezoidal block 28. When the top block 26 is on the trapezoidal block 28, the lower end of the arc tube 8 will bend towards the plant under the pressure. When the top block 26 moves away from the trapezoidal block 28, the arc tube 8 will bend back to its original position under its own elastic force. Thus, the reciprocating arc plate 25 will cause the arc tube 8 to bend back and forth, which will cause the auxiliary lamp body 9 to irradiate the plant leaves at different irradiation angles. With the continuous revolution of the arc tube 8, the auxiliary lamp body 9 will irradiate the plant leaves more evenly, further improving the effect of supplemental lighting for the plant.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been described above with reference to preferred embodiments, it is not intended to limit the present invention. Any modifications or alterations made by those skilled in the art without departing from the scope of the present invention using the above-described technical content can be considered as equivalent embodiments. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
