Description

Technical Field

[0002] Plants need light and carbon dioxide to achieve photosynthesis in order to grow. At the same time, the growth rate and health of plants are also related to the surrounding temperature.

[0003] At present, for indoor planting, the existing technology is to provide lighting through LED planting lamps, which are arranged above the plants and facing the plants, or arranged at the root position of the plants and facing the crown of the plants. The concentration of carbon dioxide in the environment is mainly maintained by ventilation devices to maintain ventilation around the plants, such as installing a second opening connected to a blower on the planting bracket, or above the plants.

[0004] However, the above prior art has many technical problems, such as: 1. When the plants grow luxuriantly, the installed fan cannot fully realize the air circulation near the plants. For example, the second opening is located on the planting support, and the air circulation of the plants on the other side far from the second opening is reduced.

[0005] 2. The LED grow light itself generates heat in the process of converting electrical energy into light.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Please refer to Figure 1 and Figure 2 The LED planting unit 100 of the present invention includes: an LED module 11, a tube 12 and a light-transmitting cover 13; the LED module 11 includes a substrate 111 and a plurality of light-emitting lamp beads 112 installed on the substrate 111, the substrate 111 is used to carry the light-emitting lamp beads 112, the light-emitting lamp beads 112 are welded on the substrate 111, the substrate 111 is used to supply power to the light-emitting lamp beads 112, and plays a role in heat dissipation; the LED module 11 is in a long strip shape, adapted to the size of the tube 12, so as to be easily installed on the tube 12. Specifically, the tube 12 is a heat-conductive metal material with an integrally formed structure. When the LED module 11 is installed on the tube 12, the tube 12 can transfer the heat of the LED module 11 to improve the heat dissipation effect.

[0023] The pipe 12 has a hollow air duct 124. The surface of the pipe 12 along the length direction is provided with at least one row of air outlet holes 121. Each row of air outlet holes 121 has a plurality of air outlet holes. The air outlet holes 121 in the same row are spaced apart from each other, and can also be equally spaced. When there is flowing air in the air duct 124 of the pipe 12, the air flows out through the air outlet holes 121, and a heat exchange channel for uniform air flow can be formed near the pipe 12, thereby preventing heat accumulation.

[0024] The LED module 11 is mounted on the outer surface of the tube 12 and arranged along the length direction of the tube 12. The substrate 111 contacts the tube 12 to conduct heat to the tube 12. The tube 12 has a first opening 122 and a second opening 123. The first opening 122 and the second opening 123 are connected through an air duct 124 and are respectively located at both ends of the tube 12. The air flowing into the air duct 124 from the first opening 122 flows out through the air outlet 121 and / or the second opening 123.

[0025] In the present invention, when the air flows in the air duct 124 of the pipe 12, on the one hand, it can realize the discharge of air from the air outlet 121, driving the heat exchange of the air around the air outlet 121. On the other hand, since the air outlet 121 is set on the pipe 12, when the air outlet 121 and the air duct 124 are blowing, the pipe 12 can be quickly cooled. The pipe 12 itself is made of heat-conducting metal material. After absorbing the heat of the substrate 111, it can realize the heat dissipation of the LED module 11 by air cooling. The clever design makes the air flow near the plant increase the oxygen content in the carbon dioxide in the air around the plant, increase the photosynthesis of the plant, and improve the heat dissipation performance of the LED module 11; the air flows through the first opening 122 to the air outlet 121 and the second opening 123. The air flows through a long length, which can dissipate heat for the pipe 12 with a long length, ensuring that the temperature of the entire pipe 12 is basically the same, thereby preventing the occurrence of heat accumulation, which is beneficial to reducing the temperature of the surrounding environment and facilitating the operation of the LED module 11.

[0026] In the present invention, the air outlet 121 is located on one side of the LED module 11 or on both sides of the LED module 11 along the length direction, and the air outlet direction of the air outlet 121 is toward the light emitting direction of the LED module 11. The LED module 11 can blow air toward the crown of the plant while illuminating the plant, thereby increasing the illumination and carbon dioxide concentration at the crown of the plant, which is beneficial to the growth of the plant.

[0027] In the present invention, the LED planting unit 100 can be arranged between two rows of plants, and the air outlets 121 located on both sides of the LED module 11 can blow air to the two rows of plants respectively. That is to say, one LED planting unit 100 can achieve the purpose of lighting the plants on both sides, exchanging air near the plants and dissipating heat, which can save space for arranging lighting devices and heat dissipation and ventilation equipment.

[0028] In the present invention, each LED planting unit 100 may correspond to multiple LED modules 11, for example, 2 or 3. Multiple LED modules 11 are distributedly arranged on the outer surface of the tube 12, for example, multiple LED modules 11 are arranged in parallel, multiple LED modules 11 are arranged along the length direction of the tube 12, with the same interval, or distributed along the circumference of the tube 12. This arrangement is conducive to improving the light intensity of the space where the tube 12 is located, which is conducive to the growth of plants.

[0029] Similarly, when there are multiple LED modules 11 on the LED planting unit 100, there are also multiple rows of air outlet holes 121, each row of air outlet holes 121 corresponds to at least one LED module 11, each row of air outlet holes 121 is located near one LED module 11, and extends along the length direction of the tube 12. Preferably, each LED module 11 corresponds to two rows of air outlet holes 121, one air outlet hole 121 is arranged on one side of the LED module 11, and the other air outlet hole 121 is arranged on the other side of the LED module 11; the air outlet holes 121 arranged in this way can also further improve the fluidity of the air near the tube 12.

[0030] In the present invention, the cross-sectional shape of the tube 12 can be set according to actual needs, such as a circular or polygonal structure. Moreover, the position of the air outlet 121 on the tube 12 can also be set according to actual needs, such as being set on both sides of the LED planting unit 100, or being set at the position of the LED planting unit 100 facing the plant, as long as the air outlet 121 can improve the air flow in the surrounding environment.

[0031] like Figure 3 and Figure 4 In the present invention, the surface of the tube 12 is provided with a mounting position P extending along the length direction of the tube, and the mounting position P is used to mount the LED module 11. The mounting position P is a part of the tube 12, or the mounting position P is a concave platform 14a or a mounting platform 14 formed on the tube 12; the concave platform 14a or the mounting platform 14 extends along the length direction of the tube 12.

[0032] In the present invention, the tube 12 has a hexagonal cross-section. In this case, a mounting platform 14 can be provided at a position of the tube 12 corresponding to one side of the hexagonal cross-section. The mounting platform 14 is used to mount the substrate 111 of the LED module 11. Figure 5 Specifically, the mounting platform 14 is located on the outer surface of the pipe 12 and extends along the length direction of the pipe 12. The mounting platform 14 includes a convex surface 141, an inner groove 142 and a convex strip 143.

[0033] The boss surface 141 protrudes from the outer surface of the tube 12 and is used to install the substrate 111; the inner groove 142 is arranged in the middle of the boss surface 141, and the inner groove 142 is arranged along the length direction of the tube 12, and the inner groove 142 is recessed toward the inside of the tube 12; there are two convex strips 143, and the two convex strips 143 are respectively located at the two side edges of the boss surface 141, and the two convex strips 143 are extended along the length direction of the tube 12, and the two convex strips 143 protrude from the edge of the width direction of the boss surface 141.

[0034] like Figure 5 The light-transmitting cover 13 of the LED planting unit 100 is connected to the pipe 12, and the LED module 11 is wrapped in the light-transmitting cover 13; the light-transmitting cover 13 is arranged along the length direction of the pipe 12; the light-transmitting cover 13 includes clamping strips 131 arranged on both sides of the light-transmitting cover 13 and extending along the length direction of the light-transmitting cover 13, and the two clamping strips 131 are respectively clamped on the two convex strips 143, so as to seal the LED module 11 in the light-transmitting cover 13; when there are multiple LED modules 11, there are also multiple light-transmitting covers 13, each of which corresponds to the LED module 11, that is, one light-transmitting cover 13 is wrapped in one LED module 11, or one light-transmitting cover 13 is included in two or more light-transmitting covers 13. The air outlet 121 is located on the outside of the light-transmitting cover 13, and the light-transmitting cover 13 does not affect the air outlet of the air outlet 121.

[0035] In the present invention, the substrate 111 is fixed to the tube 12 by screws a and the inner groove 142. The side wall of the inner groove 142 is provided with a plurality of fixing grooves 144 extending in the length direction. The screws a are fixed in the fixing groove 144 by being screwed with the internal threads provided in the fixing groove 144. The substrate 111 can be fixed in the inner groove 144 more conveniently. Since the substrate 111 is provided along the length of the boss surface 141, the length of the substrate 111 is adapted to the length of the tube 12. For example, when the length of the tube 12 is 3m, the substrate 111 is also provided with 3m, and the length of the inner groove 142 is also 3m. In this way, when the LED module 11 is fixed to the tube 12, it can be fixed at any position of the substrate 111 by screws and the inner groove 142, so as to be adapted to various lengths.

[0036] After the light-transmitting cover 13 is clamped with the convex strip 143 through the clamping strip 131, the light-transmitting cover 13 is fixed on the tube 12. The light-transmitting cover 13 is made of elastic plastic material, and the elastic structure can be conveniently fixed and disassembled, and can ensure firm fixation. One preferred way is to set a sealing strip at the connection position between the clamping strip 131 of the light-transmitting cover 13 and the tube 12, or a sealing silicone can achieve the sealing of the light-transmitting cover 13, thereby achieving a waterproof effect.

[0037] In the present invention, the LED module 11 is installed on the pipe 12 made of heat-conducting metal material. The heat generated by the light emission of the LED module 11 is dissipated through the pipe 12, which increases the heat dissipation area of ​​the LED module 11, improves the heat dissipation efficiency, and is conducive to improving the technical problem of heat accumulation; in addition, the hollow pipe 12 has an air duct 124. When air flows in the air duct 124 of the pipe 12, the air flows out through a plurality of air outlets 121 arranged at intervals, so that the air flow around the plant can be uniformly achieved; in addition, since the pipe 12 is an integrally formed structure, it is convenient to produce a suitable length according to the size of the planting area during production, so it is convenient to customize the size; finally, the LED planting unit 100 of the present application The size can also be expanded according to the quantity. For example, when there are two LED planting units 100, the two air ducts 124 of the two LED planting units 100 are connected, that is, the second opening 123 of one of the LED planting units 100 is connected to the first opening 122 of the other LED planting unit 100. In this way, the flowing air from the first opening 122 of one LED planting unit 100 can flow through the two air ducts 124 of the two LED planting units 100 in sequence, and flow out through the air outlet 121 connected to the two air ducts 124, so that the flow of air over a larger length range can be achieved.

[0038] like Figures 6 to 8 The present invention discloses a planting device 200, which includes: at least one fan 21, a plurality of wires 22 and at least one of the above-mentioned LED planting units 100, each of which includes a first end a1 and a second end a2.

[0039] When the LED planting unit 100 has one, the fan 21 is installed at the first end a1 of the LED planting unit 100, the second end a2 of the LED planting unit 100 is closed, the fan 21 blows toward the first opening 122 of the LED planting unit 100, the second opening 123 of the LED planting unit 100 is closed, and the wire 22 is used to output an electrical signal to power the LED module 11 in the LED planting unit 100; the air flowing in the air duct 124 flows out through the air outlet holes 121 arranged at intervals, thereby achieving uniform air flow.

[0040] When there are multiple LED planting units 100, the multiple LED planting units 100 are respectively the first unit 101, the second unit 102 to the Nth unit 10n, N is an integer ≥ 1, and the multiple LED planting units 100 are connected end to end in sequence, and the air ducts 124 of the multiple LED planting units 100 are coaxially connected to each other; the fan 21 is installed at the first end a1 of the first unit 101, and the second end a2 of the Nth unit 10n is closed; the fan 21 is installed at the first opening 122 of the first unit 101, and each LED planting unit 100 is connected to a wire 22, and two adjacent LED planting units 100 are connected by the wire 22, and the multiple LED modules 11 are electrically connected in sequence by the wire 22, and the wire 22 is used to output electrical signals to power and control the LED modules 11.

[0041] In the present invention, the fan 21 blows air into the air duct 124, and the flowing air flows out through the air outlet 121, which can evenly flow the surrounding air. In addition, while blowing air, the heat dissipation of the LED module 11 is achieved through the pipe 12 of the LED planting unit 100, and the blowing of air circulation and the heat dissipation of the LED module 11 are cleverly combined to solve the technical problems in the prior art. At the same time, multiple LED planting units 100 can be connected in series to achieve the connection of multiple air ducts 124. The length of the entire planting device 200 can be extended according to specific needs to meet the needs of various planting sizes; wherein, by using a wire 22 to connect multiple LED modules 11 in sequence, the lighting parameters of multiple LED modules 11 can be adjusted through a control terminal, for example, after adjustment by a control terminal, multiple LED modules 11 can have the same light intensity and light time, and the adjustment process is convenient and simple, and there is no need to adjust and control multiple LED modules 11 one by one, thereby achieving an efficient control method.

[0042] In this embodiment, two adjacent LED planting units 100 are connected by a flexible connecting tube 23, and the flexible connecting tube 23 is used to connect the air ducts 124 of the two adjacent LED planting units 100; at this time, after only one fan 21 blows air to one of the LED planting units 100, the air circulating in the air duct 124 can flow through the air ducts 124 of multiple LED planting units 100 in turn, thereby achieving heat dissipation for multiple LED modules 11 and air outlet for multiple LED planting units 100, thereby realizing the functions of heat dissipation and ventilation.

[0043] When specifically connected: the second end a2 of the Mth unit is connected to the first end a1 of the M+1th unit through the flexible connecting tube 23, so that the second opening 123 of the Mth unit is connected to the first opening 122 of the M+1th unit, M+1≤N. That is: the second end a2 of one LED planting unit 100 is connected to the first end a1 of the next adjacent LED planting unit 100 through the flexible connecting tube 23, so that the second opening 123 of the LED planting unit 100 is connected to the first opening 122 of the next LED planting unit 100.

[0044] That is to say, when there are multiple LED planting units 100, the first opening 122 of the next LED planting unit 100 is connected to the second opening 123 of the previous LED planting unit 100 through the flexible connecting tube 23; the first opening 122 of the first LED planting unit 100 is connected to the fan 21 or the fan 21 blows air to the first opening 122 of the first LED planting unit 100, and the second opening 123 of the last LED planting unit 100 is closed. Such a structure enables all the air in the air duct 124 to be blown out through the multiple air outlets 121, and the air flow rate of one fan 21 is equal to the sum of the air volume of the multiple air outlets 121, ensuring that the air blown out from the air outlet 121 is the blowing speed, thereby increasing the air exchange rate in the surrounding environment.

[0045] The planting device 200 further includes a control terminal 24, which is electrically connected to the LED module 11 of the first unit 101, and controls the plurality of LED modules 11 via the wire 22. One control terminal 24 can power and control a plurality of planting units 100, which is convenient and fast.

[0049] The locking structure 254 includes: a fixed block 2541, an outer frame 2542 and an adjusting rod 2543. The fixed block 2541 is accommodated in the opening 2521; the outer frame 2542 is sleeved on the support rod 252, and the outer frame 2542 is provided with a rotating shaft 2544 at a position relative to the opening 2521, and the length direction of the rotating shaft 2544 is the same as the length direction of the support rod 252; the adjusting rod 2543 is rotatably connected to the rotating shaft 2544, and the adjusting rod 2543 has a convex surface 2545 at a position close to the opening 2521, and the fixed block 2541 is located between the telescopic rod 253 and the convex surface 2545.

[0050] When the adjusting rod 2543 rotates, a) the raised surface 2545 abuts against the fixing block 2541 so that the fixing block 2541 is pressed against the telescopic rod 253 to fix the telescopic rod 253; or, b) the raised surface 2545 moves away from the fixing block 2541 so that the fixing block 2541 is released from the telescopic rod 253 to move the telescopic rod 253 relative to the adjusting rod 2543, thereby adjusting the position of the telescopic rod 253.

[0051] When the adjustment bracket 25 of the present invention is working, the adjustment rod 2543 is first rotated to make the raised surface 2545 move away from the fixed block 2541, and the fixed block 2541 releases the telescopic rod 253; then the telescopic rod 253 is manually stretched or compressed to make the telescopic rod 253 move in the support rod 252. After the telescopic rod 253 moves to a suitable position, the adjustment rod 2543 is manually rotated again to make the raised surface 2545 abut against the fixed block 2541, and the fixed block 2541 is pressed against the telescopic rod 253, so that the telescopic rod 253 is fixed relative to the support rod 252, thereby realizing the height adjustment of the telescopic rod 253.

[0052] The present invention adjusts the height of the LED planting unit 100 or the planting device 200 by adjusting the bracket 25, so as to ensure that the range of illumination and the air blown out from the air outlet 121 correspond to the height of the plant, thereby improving the photosynthesis efficiency of the plant and improving the growth of the plant.

[0053] like Fig.11 and Fig.12, there are multiple fans 21a, and there are multiple LED planting units 100a, each fan 21a corresponds to one LED planting unit 100a, and the planting device 200a also includes a power supply 26a, and the power supply 26a is electrically connected to the multiple fans 21a; the number of LED planting units 100a is the same as the number of fans 21a. The fans 21a are installed at the first end a1, and each fan 21a is connected to each first end a1 in a one-to-one correspondence; each LED planting unit 100a is connected to a wire 22a, and two adjacent LED planting units 100a are connected through the wire 22a, and multiple LED modules 11a and multiple fans 21a are electrically connected through the wire 22a, and the wire 22a outputs an electrical signal to power the LED module 11a and the fan 21a, and to control the LED module 11a.

[0054] like Fig.11 In the present invention, each LED planting unit 100a is provided with a fan 21a, and each fan 21a is used to blow air into the air duct 124a of an LED planting unit 100a; multiple fans 21a are connected by a wire 22a, and multiple LED modules 11a are also connected by a wire 22a. A power supply 26a can be used to independently control the operation or shutdown of multiple fans 21a, so that multiple LED planting units 100a can be operated or stopped in a differentiated manner. By connecting multiple LED modules 11a with a wire 22a, the lighting parameters of multiple LED modules 11a can be adjusted through a control terminal 24a. For example, after adjustment by a control terminal 24a, multiple LED modules 11a have the same light intensity and illumination time. The adjustment process is convenient and simple, and there is no need to adjust and control multiple LED modules 11a one by one, thereby achieving an efficient control method.

[0055] like Fig.13, the fans 21b are arranged in pairs, each pair of fans 21b has two fans (21b1, 21b2), and each pair of fans 21b is respectively arranged at the two ends of the planting unit 100b, namely the first end a1 and the second end a2; each pair of fans (21b1, 21b2) blows air toward the air duct 124b through the first opening 122 and the second opening 123 respectively; the number of fans 21b is twice the number of LED planting units 100b. Multiple pairs of fans (21b1, 21b2) are connected by wires 22b, and multiple LED modules 11b are also connected by wires 22b. Among them, a power supply 26b can be used to independently control the operation or shutdown of multiple pairs of fans (21b1, 21b2), so as to realize differentiated operation or shutdown of multiple LED planting units 100b. In particular, a power supply 26b can control a pair of fans (21b1, 21b2) installed on the same LED planting unit 100b to rotate in opposite air outlet directions, that is, one of the fans 21b1 rotates forward and blows air into the air duct 124; while the other fan 21b2 rotates reversely when installed forwardly or rotates forwardly when installed reversely, and also blows air into the air duct 124. In this case, the air blown into the air duct 124b is discharged through the air outlet 121, and the air flow rate in the air outlet 121 is further increased, thereby improving the heat dissipation of the pipe 12, and increasing the air flow near the LED planting unit 100b, thereby increasing the carbon dioxide concentration near the plant, which is beneficial to improving the growth efficiency of the plant.
