LED planting unit and planting device thereof

Description

TECHNICAL FIELD

The present disclosure relates to the field of plant cultivation devices, and especially relates to an LED planting unit and a planting device thereof.

BACKGROUND

Plants need light and carbon dioxide for performing photosynthesis during a cultivation process in order to grow. A growth rate and health of the plants are also related to environmental temperatures that surround the plants.

At present, for an indoor plant, a conventional method is to provide lighting for the indoor plant through LED planting lamps. The LED planting lamp is generally arranged above the indoor plant and faces the indoor plant, or the LED planting lamp is arranged at a root of the indoor plant and faces a crown of the indoor plant. A concentration of carbon dioxide in environments is mainly maintained through ventilation devices to keep the environments that surround the indoor plants to be ventilated, for example, a second opening of a draught fan that is configured to perform air blow is installed on a planting bracket or above the plant.

However, there are a plurality of technical problems in the related technologies mentioned above, for example:

• • firstly, when the plants are growing vigorously, the draught fan that is installed can't fully implement air circulation near the plants. For example, if the second opening is arranged on the planting bracket, the air circulation of the plants on the other side with a farther distance from the second opening decreases;
  • secondly, the LED planting lamp itself generates heat during converting electrical energy into light. After the heat is dissipated by the LED planting lamp, the heat is mainly concentrated near the plants. The air circulation of the planting plants away from the second opening decreases, so as to form a higher temperature area thereof. Such excessive temperature can also affect the growth of the plants; and
  • thirdly, the LED planting lamp itself is also difficult to dissipate the heat due to a high ambient temperature thereof, which results in a low light conversion rate and a reduction in lifespan thereof.

SUMMARY

The technical problems to be solved: in view of the shortcomings of the related art, an objective of the present disclosure is to provide an LED planting unit which can solve technical problems that a low air flow is occurred in plants that are planted in the related art and a low heat dissipation efficiency is occurred in conventional LED planting lamps.

An LED planting unit according to an embodiment of the present disclosure includes:

• • an LED module that includes a base and a plurality of lighting beads installed on the base;
  • an integral tube made of a heat conduction metal material and including a hollow passageway and at least one row of air vents arranged on an outer surface of the tube along a length direction thereof, each row of air vents including a plurality of air vents, the plurality of air vents in the same row arranged at intervals;
  • the LED module installed on the outer surface of the tube and arranged along the length direction of the tube, the base in contact with the tube to conduct heat for the tube; and wherein
  • the tube includes a first opening and a second opening connected with each other through the passageway and respectively arranged at two ends of the tube, and air that flows from the first opening and/or the second opening into the passageway flows out through the air vent.

In the present disclosure, the LED module is installed on the tube that is made of a thermally conductive metal material, so that heat generated by emitting light from the LED module is dissipated through the tube, thereby increasing a heat dissipation area of the LED module and improving a heat dissipation efficiency thereof, which is conducive to improving the technical problem of heat accumulation. Furthermore, the hollow tube has the passageway, when air flows in the passageway of the tube, air flows out through the plurality of air vents that is set at intervals, thereby implementing uniform air flow around the plants that are planted. And then, as the tube is an integral structure, it is convenient to produce a suitable length according to a size of a planting area during production, thereby making it easy to customize the size thereof. Finally, the LED planting units of the present disclosure can also be expanded in sizes according to quantities, for example, when there are two LED planting units, the two passageways of the two LED planting units are connected with each other, that is, the second opening of one LED planting unit is connected to the first opening of the other LED planting unit. In this way, the flowing air from the first opening of one LED planting unit can flow through the two passageways of the two LED planting units in sequence, and then flow out from the air vents that are connected with the passageways, which can achieve air flow within a larger length range thereof.

DETAILED DESCRIPTION

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings.

Referring to FIG. 1 and FIG. 2, FIG. 1 is an exploded, schematic view of an LED planting unit 100 in accordance with an embodiment of the present disclosure. The LED planting unit 100 includes: an LED module 11, a tube 12 and a transparent cover 13.

The LED module 11 includes a base 111 and a plurality of lighting beads 112 installed on the base 111. The base 111 is configured to support the plurality of lighting beads 112 which is welded onto the base 111. The base 111 is configured to supply power for the plurality of lighting beads 112 and also serves as a heat dissipation function thereof.

The LED module 11 is in a shape of a long strip and compatible with a size of the tube 12, so that the LED module 11 can be easily installed on the tube 12. Specifically, the tube 12 is a thermally conductive metal material with an integrated molding structure. When the LED module 11 is installed on the tube 12, the tube 12 can transfer heat of the LED module 11, thereby improving a heat dissipation effect thereof.

Furthermore, the tube 12 includes a hollow passageway 124 and at least one row of air vents 121 arranged on an outer surface of the tube 12 along a length direction thereof, each row of air vents 121 including a plurality of air vents 121, the plurality of air vents 121 in the same row arranged at intervals, of course, the plurality of air vents 121 in the same row can be arranged at equal intervals.

When there is flowing air in the passageway 124 of the tube 12, the air flows out through the plurality of air vents 121, so that a uniform air flow heat exchange channel is formed near the tube 12, thereby preventing heat accumulation thereof.

The LED module 11 is installed on the outer surface of the tube 12 and arranged along the length direction of the tube 12, and the base 111 is in contact with the tube 12 to conduct heat for the tube 12.

The tube 12 includes a first opening 122 and a second opening 123 connected with each other through the passageway 124 and respectively arranged at two ends of the tube 12, and air that flows from the first opening 122 into the passageway 124 flows out through the air vent 121 and/or the second opening 123.

In the present disclosure, when the air flows in the passageway 124 of the tube 12, on the one hand, the air can flow out of the air vent 121, so as to perform air heat exchange around the air vent 121; on the other hand, because the air vent 121 is arranged on the tube 12, when air flows from the air vent 121 and the passageway 124, heat generated from the tube 12 can be quickly dissipated out. The tube 12 itself is made of a thermally conductive metal material, which can dissipate heat that is generated by the LED module 11 through an air cooling way after the tube 12 absorbs the heat from the base 111. Such design allows the air near the plants to flow, thereby increasing an oxygen content of carbon dioxide in the air around the plants, increasing photosynthesis of the plants and improving a heat dissipation performance of the LED module 11.

The air flows out from the first opening 122 to the air vent 121 and the second opening 123. A flowing length of the air is relatively long so that it can dissipate heat from a longer tube 12, thereby ensuring that a temperature of the entire tube 12 is basically consistent for preventing heat accumulation thereof, which is not only beneficial for reducing a temperature of the surrounding environment, but also for an operation of the LED module 11.

In the present disclosure, the air vent 121 is arranged on a side of the LED module 11 or on both sides of the LED module 11 along a length direction thereof, and an air outlet direction of the air vent 121 faces a light emission direction of the LED module 11. The LED module 11 can blow air towards a crown of the plant while providing light for the plant, thereby increasing the light and a concentration of carbon dioxide at the crown, which is beneficial for the growth of the plant.

In the present disclosure, the LED planting unit 100 can be arranged between two rows of plants that are planted, and the air vents 121 arranged on both sides of the LED module 11 can blow air to the two rows of planting plants, respectively. That is to say, only one LED planting unit 100 can achieve a purpose of lighting the plants that are planted on both sides, exchanging air near the planting plants and dissipating heat thereof, which can save a space for arranging lighting devices, heat dissipation and ventilation devices thereof.

In the present disclosure, each LED planting unit 100 can correspond to a plurality of LED modules 11, such as two LED modules 11 or three LED modules 11. The plurality of LED modules 11 are distributed and arranged on the outer surface of the tube 12, for example, the plurality of LED modules 11 is arranged in parallel, the plurality of LED modules 11 is arranged along the length direction of the tube 12 with the same interval, or distributed along the circumference of the tube 12. Such setting way is conducive to increasing light intensity of a space where the tube 12 is located, which is beneficial for the growth of the plants.

Similarly, when there is the plurality of LED modules 11 arranged on the LED planting unit 100, there is also a plurality of rows of air vents 121 arranged thereon, and each row of air vents 121 at least correspond to one of the plurality of LED modules 11. Each row of air vents 121 is located near one of the plurality of LED modules 11 and extends along the length direction of the tube 12. Preferably, each LED module 11 corresponds to two rows of air vents 121, and one row of air vents 121 is arranged on one side of the LED module 11 and the other row of air vents 121 is arranged on the other side of the LED module 11. The two rows of air vents 121 that are arranged on both sides of the LED module 11 can also further improve air flow near the tube 12.

In the present disclosure, a cross-sectional shape of the tube 12 can be set according to actual needs, such as a circular structure or a polygonal structure. Moreover, positions of the air vents 121 that are arranged on the tube 12 can also be set according to actual needs, for example, the air vents 121 are arranged on both sides of the LED planting unit 100, or at a position where the LED planting unit 100 faces the planting plants, as long as the air vents 121 can improve the air flow of the surrounding environment.

Referring to FIG. 3A and FIG. 3B, in the present disclosure, an installation position P is arranged on the outer surface of the tube 12 and extends along the length direction of the tube 12 and configured to install the LED module 11. The installation position P is a part of the tube 12, or the installation position P is a concave portion 14a or an installation portion 14 formed on the tube 12; the concave portion 14a or the installation portion 14 extends along the length direction of the tube 12.

In the present disclosure, it is preferred that the tube 12 is a hexagonal cross-sectional shape. In this way, the installation portion 14 can be arranged at a position of the tube 12 that corresponds to an edge of a hexagonal cross-section of the tube 12. The installation portion 14 is configured to install the base 111 of the LED module 11. Referring to FIG. 4, specifically, the installation portion 14 is arranged on the outer surface of the tube 12 and extends along the length direction of the tube 12. The installation portion 14 includes: a convex surface 141, a concave recess 142 and a bar 143.

The convex surface 141 protrudes out of the outer surface of the tube 12 and is configured to install the base 111. The concave recess 142 is arranged on the middle of the convex surface 141 and arranged along the length direction of the tube 12, wherein the concave recess 142 is concave towards the interior of the tube 12. There are a pair of bars 142 included in the installation portion 14, and the pair of bars 142 are respectively located on both edges of the convex surface 141, extend along the length direction of the tube 12 and protrude from edges in a width direction of the convex surface 141.

Referring to FIG. 4, the transparent cover 13 is connected to the tube 12, and the LED module 11 is received in the transparent cover 13. The transparent cover 13 is arranged along the length direction of the tube 12 and includes two ribs 131 arranged on both sides thereof and extending along the length direction thereof, the two ribs 131 respectively clamped with the pair of bars 143, so as to seal the LED module 11 inside the transparent cover 13.

When there are a plurality of LED modules 11, there are also a plurality of transparent covers 13, and each of the plurality of transparent covers 13 corresponds to one of the plurality of LED modules 11. That is to say, one transparent cover 13 is wrapped around one LED module 11, or one transparent cover 13 is included in two or more transparent covers 13. The air outlet 121 is located on the outside of the transparent cover 13, and the transparent cover 13 does not affect air flowing from the air outlet 121.

In the present disclosure, the base 111 is fixed in the concave recess 142 by screws a and further fixed with the tube 12, and a plurality of fixing recesses 144 extending along a length direction of the concave recess 142 is provided on a sidewall of the concave recess 142, the screws a and the plurality of fixing recesses 144 are in threaded connection so as to fix the screws a within the plurality of fixing recesses 144.

In the present disclosure, the base 111 can be conveniently fixed in the concave recess 142. As the base 111 is set along the length of the convex surface 141, the length of the base 111 is adapted to that of the tube 12, for example, when the length of the tube 12 is 3 m, the base 111 is also set to 3 m, and the length of the concave recess 142 is also 3 m. In this way, when the LED module 11 is fixed on the tube 12, it can be fixed to the concave recess 142 at any position of the base 111 by the screws, thereby making it convenient to adapt to various lengths thereof.

After the ribs 131 of the transparent cover 13 are clamped with the bars 143, the transparent cover 13 is fixed on the tube 12. The transparent cover 13 is made of an elastic plastic material, which can be easily fixed and disassembled through an elastic structure, and can ensure firm fixation thereof. A preferred method that a sealing strip or a sealing silicone is installed at the position that the rib 131 of the transparent cover 13 is connected with the tube 12, which can seal the transparent cover 13 and thus play a waterproof role thereof.

In the present disclosure, the LED module 11 is installed on the tube 12 that is made of a thermally conductive metal material, so that heat generated by emitting light from the LED module 11 is dissipated through the tube 12, thereby increasing a heat dissipation area of the LED module 11 and improving a heat dissipation efficiency thereof, which is conducive to improving the technical problem of heat accumulation. Furthermore, the hollow tube 12 has the passageway 124, and when air flows in the passageway 124 of the tube 12, air flows out through the plurality of air vents 121 that is set at intervals, thereby implementing uniform air flow around the plants. And then, as the tube 12 is an integral structure, it is convenient to produce a suitable length according to a size of a planting area during production, thereby making it easy to customize the size thereof. Finally, the LED planting units 100 of the present disclosure can also be expanded in sizes according to quantities, for example, when there are two LED planting units 100, the two passageways 124 of the two LED planting units 100 are connected with each other, that is, the second opening 123 of one LED planting unit 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 passageways 124 of the two LED planting units 100 in sequence, and then flow out from the air vents 121 that are connected with the passageways 124, which can achieve air flow in a larger length range thereof.

Specifically, the number of the LED planting units 100a is the same as that of the draught fans 21a.

The draught fan 21a is installed at the first portion a1, each draught fan 21a corresponding to connect to each first portion a1 one-to-one, a wire 22a connected to each LED planting unit 100a, two adjacent LED planting units 100a connected by the wire 22, the plurality of LED modules 11a electrically connected to the plurality of draught fans 21a by the wires 22a, and the wire 22a configured to supply power for the plurality of LED modules 11a and the plurality of draught fans 21a, and output electrical signals to control the plurality of LED modules 11a.

Referring to FIG. 10, in the present disclosure, each LED planting unit 100a is provided one draught fan 21a to blow air towards the passageway 124a of the LED planting unit 10a. The plurality of draught fans 21a is connected by the wires 22a, and the plurality of LED modules 11a is also connected by the wires 22a. Only one power supply 26a is provided to independently control operation or shutdown of the plurality of draught fans 21a, thereby achieving differentiated operation or shutdown of the plurality of LED planting units 100a. The plurality of LED modules 11a is connected by a single wire 22a, it is possible to adjust lighting parameters of the plurality of LED modules 11a through a single control terminal 24a. For example, after adjusting by only one control terminal 24a, the plurality of LED modules 11a can have the same lighting intensity and lighting time, so that an adjustment process is convenient and simple, and there is no need to individually adjust and control the plurality of LED modules 11a, thereby achieving an efficient control way thereof.

The third embodiment of the present disclosure

Referring to FIG. 12, differences between the third embodiment and the second embodiment are that: in the third embodiment, there are a plurality of draught fans 21b arranged in pairs, each pair of draught fans 21b having two draught fans 21b1, 21b2, and each pair of draught fans 21b is respectively arranged at both ends of the planting unit 100b, namely the first portion a1 and the second portion a2. Each pair of draught fans 21b1, 21b2 blows air towards the passageway 124b through the first opening 122 and the second opening 123, respectively.

In the third embodiment of the present disclosure, the number of draught fans 21b is twice the number of LED planting units 100b.

In the third embodiment of the present disclosure, a plurality of pairs of draught fans 21b is connected by the wires 22b, and the plurality of LED modules 11b is also connected by the wires 22b. Only one power supply 26b is provided to independently control operation or shutdown of the plurality of pairs of draught fans 21b1, 21b2, thereby achieving differentiated operation or shutdown of the plurality of LED planting units 100b. In particular, only one power supply 6b can control the pair of draught fans 21b1, 21b2 installed on the same LED planting unit 10b to rotate in opposite directions, that is, one draught fan 21b1 rotates in a forward direction and blows air towards the passageway 124b, and the other draught fan 21b2 rotates in a reverse direction when being installed in a forward direction, or rotates in the forward direction when being installed in the reverse direction, and also blows air towards the passageway 124b. In this case, the air blown into the passageway 124b is discharged through the air vent 121, so that an air flow velocity in the air vent 121 is further increased, which can improve the heat dissipation of the tube 12, increase the air flow near the LED planting unit 100b, and improve the concentration of carbon dioxide near the plants, thereby being conducive to improving the growth efficiency of the plants.

Although the features and elements of the present disclosure are described as embodiments in particular combinations, each feature or element can be used alone or in other various combinations within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. Any variation or replacement made by one of ordinary skill in the related art without departing from the spirit of the present disclosure shall fall within the protection scope of the present disclosure.
