[0002] Red and blue light combination, this is the most common LED plant light spectrum combination, usually the ratio of red light to blue light is set between 4:1-9:1, and the specific ratio is adjusted according to different plant species and growth stages. For example, for leafy plants, the proportion of blue light can be appropriately increased in the early growth stage to promote leaf growth; in the later growth stage, the proportion of red light can be increased to improve plant yield and quality.

[0003] Full spectrum combination: Full spectrum LED plant lights are a light source that simulates the solar spectrum, including the wavelength range of visible light and some invisible light. Full spectrum light sources can provide more comprehensive lighting for plants, promote plant growth and development, and improve plant quality and stress resistance. However, the cost of full spectrum LED plant lights is relatively high, and they are widely used in some plant planting scenarios with high lighting requirements.

[0004] In the prior art, the light source of LED plant lights is mostly a light strip with independent lamp beads. During the long-term use of the light strip, a few lamp beads may be damaged, and the lamp beads are directly fixed to the main body of the light strip. When adjusting the proportion of the lamp beads, the entire light strip needs to be replaced, and it is inconvenient to replace each damaged lamp bead individually. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an LED plant light source with replaceable lamp beads.

[0006] The technical solution adopted to solve the above technical problems is: an LED plant light source, including a light strip body, and a plurality of evenly distributed lamp bead structures for emitting light are arranged on the surface of the light strip body.

[0007] Through the above technical solution, the light strip body can be installed with a lamp bead structure, and emit light through the lamp bead structure to provide the necessary light source for plant growth.

[0008] Two copper foil strips for conducting electricity are fixedly connected to the inner side of the light strip body, and the two copper foil strips are fixedly connected to the positive and negative poles of an external power socket.

[0009] Through the above technical solution, the conductive copper foil strip can achieve electrical conductivity, and transmit the electrical energy at the external power socket position to the corresponding lamp bead structure position, thereby providing electrical energy for the lamp bead structure to emit light.

[0010] Furthermore, the lamp bead structure includes a first lamp bead body, and two symmetrically arranged annular electrodes are fixedly connected to the lower surface of the first lamp bead body, and the annular electrodes are fixedly connected to the positive and negative poles of the first lamp bead body.

[0012] Furthermore, a positioning pin is fixedly connected to the middle position of the lower surface of the first lamp bead body, and a positioning groove is opened on the upper surface of the light strip body directly below the positioning pin. The positioning pin is slidably connected to the inner wall of the positioning groove, and the size and shape of the positioning pin are consistent with the size and shape of the positioning groove.

[0013] Through the above technical solution, the first lamp bead body can be stably and accurately fixed on the surface of the light strip body through the positioning pin and the positioning groove, and the positioning pin and the positioning groove are both conical in shape to facilitate positioning and engagement.

[0014] Furthermore, a conductive groove is provided on the surface of the light strip body just below the annular electrode, and the conductive groove extends to the surface of the copper foil strip, and a through groove is provided on the lower surface of the light strip body just below the conductive groove, and the inner diameter of the through groove is smaller than the inner diameter of the conductive groove.

[0015] Through the above technical solution, the conductive groove can cooperate with the annular electrode, so that the annular electrode is inserted into the main body of the light strip and fully contacts the copper foil strip. The setting of the through groove facilitates the penetration of the insulating staple, and the inner diameter of the through groove is smaller than the inner diameter of the conductive groove, so that the copper foil strip can be supported, avoiding the annular electrode from applying excessive force on the copper foil strip and causing damage to the copper foil strip.

[0016] Furthermore, a fixing ring is provided on the lower surface of the light strip body below the through groove, and a plurality of evenly distributed insulating staples are fixedly connected to the inner wall of the tightening screw sleeve, and the insulating staples are clamped with the fixing rings at corresponding positions. The lower surface of the annular electrode is fitted with the corresponding position of the upper surface of the copper foil strip, and the annular electrode is made of pure copper material, and the tightening screw sleeve, insulating staples and fixing ring are all made of plastic materials.

[0017] Through the above technical scheme, the fixing clamp ring and the insulating pin are engaged and fixed with each other, which can effectively realize the fixing of the first lamp bead body on the surface position of the lamp strip body. The annular electrode is made of pure copper material, which has good conductivity. The threaded tightening screw sleeve makes the insulating pin engage with the fixing clamp ring. The insulating pin is rotated to move the tightening screw sleeve toward the inside of the annular electrode, so that the insulating pin and the fixing clamp ring are tightened with each other, so that the annular electrode and the copper foil strip are fully attached. The tightening screw sleeve, the insulating pin and the fixing clamp ring are all made of plastic materials, which have good insulation properties to avoid leakage.

[0018] Furthermore, the lamp bead structure includes a plurality of lamp bead attachments evenly fixed to the surface of the main body of the light strip, and the light-emitting lamp bead structure is clamped at the positions of the plurality of lamp bead attachments.

[0021] Through the above technical solution, the second lamp bead body will emit light after being powered by the movable electrode, providing protection for plant growth.

[0022] Furthermore, the lamp bead accessory includes a fixed outer frame fixedly connected to the light strip body, and the second lamp bead body is slidably connected to the inner wall of the fixed outer frame at a corresponding position, and two symmetrically arranged control outer frames are fixedly connected at both sides of the fixed outer frame.

The magnetic attraction column is slidably connected with the side wall of the fixed outer frame and slides with the inner wall of the attraction groove. The magnetic attraction column is attracted to the attraction magnet.

[0024] Through the above technical solution, the positioning cylinder can limit and support the magnetic column, so that the magnetic column can accurately slide into the attraction groove. When the magnetic column slides into the attraction groove and is fixed by the attraction magnet, the second lamp bead body can be fully fixed in the fixed outer frame position, so that the second lamp bead body is installed and fixed.

[0026] Through the above technical scheme, the reset fixing spring can make the magnetic column automatically reset when the control button is released. When the control button is pulled, the traction line is pulled, so that the magnetic column is separated from the suction groove position, and the second lamp bead body can be removed from the fixed outer frame position, which is convenient for replacing the second lamp bead body. The limiting ring can ensure that the magnetic column will not be separated from the positioning tube position when the traction line is pulled, making the magnetic column more stable to use.

[0027] Furthermore, the surface of the light strip body is embedded with two symmetrically arranged fixed electrodes at the fixed outer frame position, the movable electrode is slidably connected to the fixed electrode at the corresponding position, and a transfer wire is fixedly connected between the fixed electrode and the copper foil strip at the corresponding position.

[0028] Through the above technical solution, the fixed electrode is embedded and fixed with the lamp strip body, and connected with the copper foil strip through the transfer wire.

The lamp strip main body 1 can be installed with the lamp bead structures 2, and emits light through the lamp bead structures 2 to provide the necessary light source for plant growth.

[0043] The lamp bead structure 2 includes a first lamp bead body 20, and two symmetrically arranged annular electrodes 21 are fixedly connected to the lower surface of the first lamp bead body 20. The annular electrodes 21 are fixedly connected to the positive and negative poles of the first lamp bead body 20. A threaded groove is opened in the middle position of the lower surface of the annular electrode 21, and a tightening screw sleeve 23 is threadedly connected to the threaded groove. The first lamp bead body 20 serves as a light-emitting body, and the annular electrode 21 arranged in an annular manner can conduct electric energy at the position of the copper foil strip 3 to the position of the first lamp bead body 20, thereby realizing the connection between the first lamp bead body 20 and the copper foil strip 3.

[0044] A positioning pin 27 is fixedly connected to the middle position of the lower surface of the first lamp bead body 20, and a positioning groove 28 is opened on the upper surface of the light strip body 1 directly below the positioning pin 27. The positioning pin 27 is slidably connected to the inner wall of the positioning groove 28. The size and shape of the positioning pin 27 are consistent with the size and shape of the positioning groove 28. The first lamp bead body 20 can be stably and accurately fixed on the surface of the light strip body 1 through the positioning pin 27 and the positioning groove 28, and the positioning pin 27 and the positioning groove 28 are both conically set to facilitate positioning and engagement.

[0045] A fixing ring 24 is arranged on the lower surface of the main body 1 of the light strip below the through groove 25, and a plurality of evenly distributed insulating staples 22 are fixedly connected to the inner wall of the tightening screw sleeve 23, and the insulating staples 22 are clamped with the fixing ring 24 at the corresponding position, and the lower surface of the annular electrode 21 is fitted with the corresponding position of the upper surface of the copper foil strip 3. The annular electrode 21 is made of pure copper material, and the tightening screw sleeve 23, the insulating staples 22 and the fixing ring 24 are all made of plastic material. The fixing ring 24 and the insulating staples 22 are clamped and fixed with each other, which can effectively realize the fixing of the first lamp bead main body 20. It is fixed on the surface of the light strip body 1. The annular electrode 21 is made of pure copper material, which has good conductivity. The threaded tightening screw sleeve 23 makes the insulating pin 22 engage with the fixing ring 24. Then, the insulating pin 22 is rotated to move the tightening screw sleeve 23 toward the inside of the annular electrode 21, so that the insulating pin 22 and the fixing ring 24 are tightened with each other, so that the annular electrode 21 is fully attached to the copper foil strip 3.

[0046] A conductive groove 26 is provided on the surface of the light strip main body 1 just below the annular electrode 21, and the conductive groove 26 extends to the surface of the copper foil strip 3. A through groove 25 is provided on the lower surface of the light strip main body 1 just below the conductive groove 26. The inner diameter of the through groove 25 is smaller than the inner diameter of the conductive groove 26. The conductive groove 26 can cooperate with the annular electrode 21 so that the annular electrode 21 is inserted into the light strip main body 1 and fully contacts the copper foil strip 3. The setting of the through groove 25 facilitates the penetration of the insulating staple 22, and the inner diameter of the through groove 25 is smaller than the inner diameter of the conductive groove 26, so that the copper foil strip 3 can be supported, thereby preventing the annular electrode 21 from applying excessive force on the copper foil strip 3 and causing damage to the copper foil strip 3.

[0047] Two copper foil strips 3 for conduction are fixedly connected to the inner side of the light strip main body 1. The two copper foil strips 3 are fixedly connected to the positive and negative poles of the external power socket. The conductive copper foil strips 3 can conduct electricity and conduct the electrical energy at the position of the external power socket to the corresponding position of the lamp bead structure 2, thereby providing electrical energy for the lamp bead structure 2 to emit light.

[0048] The working principle of this embodiment is as follows: the copper foil strip 3 is powered by an external power socket, and the energy is then transferred to the two annular electrodes 21 through the copper foil strip 3, so that the first lamp bead body 20 obtains electrical energy, and the first lamp bead body 20 emits light. After a period of use, when the first lamp bead body 20 is damaged or the ratio of several first lamp bead bodies 20 at the position of the lamp strip body 1 needs to be adjusted, the first lamp bead body 20 needs to be disassembled and replaced with the required undamaged first lamp bead body 20.

[0049] When replacing the required first lamp bead body 20, rotate the insulating pin 22 at the position of the fixed clamp ring 24, so that the tightening screw sleeve 23 rotates inside the annular electrode 21, so that the tightening screw sleeve 23 is rotated and removed from the inside of the annular electrode 21, and the first lamp bead body 20 at the corresponding position loses its fixation, and the first lamp bead body 20 can be disassembled.

The lamp bead attachments 4, as a part of the lamp bead structure 2, can fully clamp and fix the luminous lamp bead structure 5, and a detachable structure is arranged at the position of the lamp bead attachments 4 to facilitate the disassembly and replacement of the luminous lamp bead structure 5.

[0052] The luminous lamp bead structure 5 includes a second lamp bead body 42 fixedly connected to one side with two symmetrically arranged active electrodes 6, and the two active electrodes 6 are fixedly connected to the positive and negative poles of the second lamp bead body 42. Two symmetrically arranged attraction grooves 43 are provided on both sides of the second lamp bead body 42, and the inner walls of the two attraction grooves 43 are fixedly connected with attraction magnets 41. The second lamp bead body 42 will emit light after being powered by the active electrodes 6, providing protection for plant growth.

[0053] The surface of the lamp strip main body 1 is embedded and fixedly connected with two symmetrically arranged fixed electrodes 7 at the position of the fixed outer frame 40, the movable electrode 6 is slidably connected to the fixed electrode 7 at the corresponding position, and a transfer wire 8 is fixedly connected between the fixed electrode 7 and the copper foil strip 3 at the corresponding position.

A limiting ring 410 is fixedly connected to the inner wall of the positioning tube 45 away from the attraction magnet 41. The reset fixing spring 48 can ensure that the magnetic column 44 can be automatically reset when the control button 47 is released. When the control button 47 is pulled, the traction wire 46 is pulled, so that the magnetic column 44 is disengaged from the attraction groove 43, and the second lamp bead body 42 can be removed from the fixed outer frame 40, which is convenient for replacing the second lamp bead body 42. The limiting ring 410 can ensure that the magnetic column 44 will not be disengaged from the positioning tube 45 when the traction wire 46 is pulled, so that the use of the magnetic column 44 is more stable.

[0057] The working principle of this embodiment is as follows: the copper foil strip 3 is powered by an external power socket, so that the copper foil strip 3 powers the transfer conductor 8 and the fixed electrode 7, so that the second lamp bead body 42 is powered on and emits light. After a period of use, if the second lamp bead body 42 is damaged or the ratio of several second lamp bead bodies 42 at the position of the lamp strip body 1 needs to be adjusted, the second lamp bead body 42 needs to be disassembled and replaced with the required undamaged second lamp bead body 42.

[0058] Pull the control buttons 47 on both sides to make the traction line 46 pull the magnetic post 44, and the magnetic post 44 is pulled out of the attraction groove 43, so that the magnetic post 44 is separated from the attraction magnet 41, and the second lamp bead body 42 can be slid out of the fixed outer frame 40, and the movable electrode 6 is separated from the fixed electrode 7.
