[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0051] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0054] like Figure 1 and Figure 2 As shown, this embodiment provides a plant lamp, including a lamp holder 1, a light-emitting component 2, and a connecting component 4. The light-emitting component 2 includes a plurality of light-emitting units 21. Each light-emitting unit 21 is mounted on the lamp holder 1 via at least one connecting component 4. The connecting component 4 is configured to selectively lock the corresponding light-emitting unit 21 to the lamp holder 1 so that the light-emitting unit 21 is fixed relative to the lamp holder 1, or to unlock so that the light-emitting unit 21 can rotate relative to the lamp holder 1 to adjust the light-emitting direction of the light-emitting unit 21.

[0055] The plant light provided in this embodiment is equipped with multiple light-emitting units 21. Each light-emitting unit 21 can rotate relative to the lamp holder 1 to adjust the light emission direction of the light-emitting unit 21. The light-emitting unit 21 is locked to the lamp holder 1 by the connecting component 4. The light emission intensity of the light-emitting component 2 can be adjusted by adjusting the light emission direction of each light-emitting unit 21 to meet the light intensity requirements of different plants and different growth stages of the same plant. Moreover, the light emission direction of the plant light can be adjusted according to the actual installation position of the plant light to meet the installation requirements.

[0056] Optionally, multiple light-emitting units 21 are spaced apart along a first direction, and the light-emitting units 21 extend along a second direction, with the second direction and the first direction intersecting. Each light-emitting unit 21 is mounted to the lamp holder 1 at both ends of the second direction via a connecting component 4. The rotation axis 43 of the light-emitting unit 21 relative to the lamp holder 1 extends along the second direction. By arranging multiple light-emitting units 21 spaced apart along the first direction, interference will not occur between the light-emitting unit 21 and its adjacent light-emitting units when the light-emitting direction of the light-emitting unit 21 is adjusted.

[0057] For example, there are three light-emitting units 21. The second direction is perpendicular to the first direction. When the plant light is suspended, both the first and second directions are perpendicular to the vertical direction. The first direction, the second direction, and the vertical direction are respectively the L1 direction, L2 direction, and L3 direction shown in the figure. The lamp holder 1 is a rectangular frame. It should be noted that the angle between the second direction and the first direction is not limited to being perpendicular, and the lamp holder 1 is not limited to being a rectangular frame; the number of light-emitting units 21 is not limited to three, but can also be two, four, five, or more.

[0058] The light-emitting component 2 has four operating states: normal operating state, focusing state, polarizing state, and diffusing state. Taking three light-emitting units 21 as an example, the operating states of the light-emitting component 2 will be briefly introduced.

[0059] Figure 3 The image shows the normal working state of the light-emitting component 2. The light-emitting direction of each light-emitting unit 21 is vertical.

[0060] Figure 4 The image shows the focusing state of the light-emitting component 2. The light-emitting unit 21 in the middle emits light in a vertical direction when it is working. The light emitted by the two light-emitting units 21 on both sides converges towards the light emitted by the light-emitting unit 21 in the middle.

[0061] Figure 5 The diagram shows the polarization state of the light-emitting component 2. The light emission direction of each light-emitting component 2 when it is working intersects with the vertical direction, and the light emitted by the three light-emitting components 2 is deflected to the same side.

[0062] Figure 6 The diagram shows the light-expanding state of the light-emitting component 2. When the light-emitting unit 21 in the middle is working, the light emission direction is vertical. When the light-emitting units 21 on both sides are working, the light emitted is expanded outward relative to the light emitted by the light-emitting unit 21 in the middle.

[0063] Optionally, such as Figure 1 As shown, each light-emitting unit 21 is mounted to the lamp holder 1 at one of its opposite ends via a connecting component 4. In this embodiment, the light-emitting unit 21 is mounted to the lamp holder 1 at both ends in the second direction via a connecting component 4. With this configuration, after the light-emitting direction of the light-emitting unit 21 is adjusted, the two connecting components 4 can keep the light-emitting unit 21 stable relative to the lamp holder 1, thereby improving the stability of the light-emitting unit 21.

[0064] Optionally, such as Figures 7 to 10 As shown, the connecting component 4 includes a connecting unit 41, which includes a first connecting portion 411 and a second connecting portion 412. The first connecting portion 411 is disposed in one of the light-emitting unit 21 and the lamp holder 1; the second connecting portion 412 is disposed in the other of the light-emitting unit 21 and the lamp holder 1, and the second connecting portion 412 can be inserted into or separated from the first connecting portion 411. In this embodiment, the first connecting portion 411 is disposed in the light-emitting unit 21, and the second connecting portion 412 is disposed in the lamp holder 1.

[0065] Specifically, the first connecting part 411 includes a connecting plate 4111, on which a plurality of locking holes 4112 are provided. The plurality of locking holes 4112 are distributed circumferentially along the rotation axis 43 of the light-emitting unit 21 relative to the lamp holder 1. The second connecting part 412 is a protruding structure, which can be inserted into any of the locking holes 4112. The connecting plate 4111 can undergo elastic deformation so that the first connecting part 411 can be separated from the second connecting part 412. For example, each connecting plate 4111 is provided with three locking holes 4112. It should be noted that the number of locking holes 4112 is not limited to three, but can also be four, five or more, which can achieve more precise adjustment of the light emission direction.

[0066] When it is necessary to adjust the light emission direction of any light-emitting unit 21, simply apply an external force to the connecting plate 4111 in the opposite direction to when the protruding structure is inserted into the locking hole 4112. The connecting plate 4111 will undergo elastic deformation, causing the protruding structure to gradually exit the locking hole 4112. After the protruding structure exits the locking hole 4112, rotate the light-emitting unit 21, align the protruding structure with the appropriate locking hole 4112, and then remove the external force applied to the connecting plate 4111 to allow the connecting plate 4111 to return to its natural state. During this process, the protruding structure will gradually insert into the locking hole 4112. The structure is simple and the operation is convenient.

[0067] The method of inserting or separating the first connecting part 411 and the second connecting part 412 described above is for manually adjusting the light emission direction of the light-emitting unit 21. In another embodiment, each light-emitting unit 21 can also be equipped with an electric drive structure such as a motor, and the output shaft of the motor can be connected to the rotating shaft 43 for transmission. The motor drives the rotating shaft 43 to rotate the light-emitting unit 21, thereby realizing the automatic adjustment of the light emission direction of the light-emitting unit 21.

[0068] In other embodiments, the connecting unit 41 may also employ other structures for manually adjusting the light emission direction of the light-emitting unit 21. Specifically, the connecting unit 41 includes a first connecting hole, a second connecting hole, and a locking member. The first connecting hole is located in one of the light-emitting unit 21 and the lamp holder 1; the second connecting hole is located in the other of the light-emitting unit 21 and the lamp holder 1. The second connecting hole is an arc-shaped hole and is coaxial with the rotation axis 43 of the light-emitting unit 21 relative to the lamp holder 1. The locking member passes through the first connecting hole and the second connecting hole. The locking member can move circumferentially along the rotation axis 43 within the second connecting hole and can lock the light-emitting unit 21 and the lamp holder 1. For example, the first connecting hole is provided on the lamp holder 1, and the second connecting hole is provided on the connecting plate 4111. The locking member is a bolt and a nut. After the bolt passes through the first connecting hole and the second connecting hole, the nut is connected. After the light-emitting unit 21 rotates to a suitable position, the nut is tightened, and the head of the bolt abuts against the connecting plate 4111, thereby locking the light-emitting unit 21 and the lamp holder 1. It should be noted that the coaxial line mentioned above is not 100% coaxial. Rather, considering the processing error, it is sufficient that when the light-emitting unit 21 is rotated, the connecting plate 4111 can rotate under the drive of the rotating shaft 43 and can be inserted into any of the second connecting holes.

[0069] Furthermore, in order to improve the stability of the light-emitting unit 21 when locking the light-emitting unit 21 and the lamp holder 1 through the connecting unit 41 and to facilitate the adjustment of the light-emitting direction of the light-emitting unit 21, the connecting assembly 4 also includes a mounting base 42. The mounting base 42 is connected to the lamp holder 1. One end of the rotating shaft 43 is connected to the light-emitting unit 21, and the other end passes through the mounting base 42 and is connected to one end of the connecting plate 4111. The rotating shaft 43 is rotatably connected to the mounting base 42, and the locking hole 4112 is provided at the other end of the connecting plate 4111.

[0070] After the protruding structure disengages from the locking hole 4112, the mounting bases 42 located at both ends of the light-emitting unit 21 support the light-emitting unit 21, preventing the light-emitting unit 21 from separating from the lamp holder 1, and facilitating the rotation of the light-emitting unit 21 to align the protruding structure with the appropriate locking hole 4112. After the protruding structure is inserted into the locking hole 4112, the light-emitting unit 21 is locked to the lamp holder 1 by the insertion of the protruding structure and the locking hole 4112, while the mounting bases 42 support the light-emitting unit 21, reducing the connection strength requirements when the protruding structure and the locking hole 4112 are inserted.

[0071] To connect the light-emitting unit 21 and the connecting plate 4111 via the rotating shaft 43, one end of the rotating shaft 43 is connected to a connecting seat 44, which is connected to the light-emitting unit 21 by fasteners. The other end of the rotating shaft 43 is provided with a threaded hole 431, and the connecting plate 4111 is provided with a through hole 4114. A bolt is passed through the through hole 4114 and threaded into the threaded hole 431, connecting the rotating shaft 43 and the connecting plate 4111. To prevent the rotating shaft 43 from rotating relative to the connecting plate 4111, a positioning hole 4113 is provided on one of the connecting plate 4111 and the rotating shaft 43, and a positioning protrusion 432 is provided on the other. The positioning hole 4113 and the positioning protrusion 432 are inserted into each other. For example, the positioning hole 4113 is provided on the connecting plate 4111, and the positioning protrusion 432 is provided on the axial end face of the rotating shaft 43. Two positioning protrusions 432 are provided, and the two positioning protrusions 432 and the threaded hole 431 are distributed in the same direction. The threaded hole 431 is located between the two positioning protrusions 432. In order to simplify the machining of positioning hole 4113 and through hole 4114, the radial sidewalls of positioning hole 4113 and through hole 4114 are opened to form an elliptical hole.

[0072] Furthermore, the second connecting part 412 also includes a limiting part, which abuts against the connecting plate 4111 when the protruding structure is inserted into any locking hole 4112. Specifically, the protruding structure is a stepped structure, which includes a small-diameter section that can be inserted into any locking hole 4112, and a large-diameter section that connects the small-diameter section to the lamp holder 1. The stepped surface formed by the small-diameter section and the large-diameter section is the limiting part. It should be noted that the limiting part is not limited to the stepped surface of the above-mentioned stepped structure; the limiting part can also be directly installed on the lamp holder 1.

[0073] The insertion of the protruding structure and the locking hole 4112 is limited by the limiting part to prevent excessive insertion depth, which would make it difficult for the protruding structure to disengage from the locking hole 4112; moreover, the structure is simple and easy to process. In order to facilitate the insertion of the protruding structure and the locking hole 4112, the outer surface of the protruding structure is arc-shaped. When the protruding structure is inserted into the locking hole 4112, the outer surface of the protruding structure has a guiding function for the connecting plate 4111, making it easier for the protruding structure to be inserted into the locking hole 4112.

[0074] Furthermore, such as Figure 1 and Figure 2 As shown, the light-emitting unit 21 includes a light-emitting side and a non-light-emitting side arranged opposite to each other. Since the light-emitting unit 21 generates a lot of heat during operation, in order to dissipate heat from the light-emitting unit 21 in a timely manner and avoid overheating of the light-emitting unit 21, thus affecting the service life of the light-emitting unit 21, the light-emitting component 2 also includes a heat dissipation unit 22. The heat dissipation unit 22 is located on the non-light-emitting side. The heat dissipation unit 22 corresponds to and is connected to the light-emitting unit 21. The heat dissipation unit 22 is used to dissipate heat from the corresponding light-emitting unit 21.

[0075] Optionally, the light-emitting unit 21 has a plate-like structure, and the heat dissipation unit 22 includes a heat dissipation plate 221 and a plurality of heat dissipation fins 222 disposed on one side of the heat dissipation plate 221. The other side of the heat dissipation plate 221 is disposed in close contact with the non-light-emitting side of the corresponding light-emitting unit 21. The heat dissipation plate 221 is connected to the corresponding light-emitting unit 21 by a plurality of fasteners, so that the heat dissipation plate 221 and the light-emitting unit 21 have a large contact area, thereby improving the heat dissipation effect of the light-emitting unit 21.

[0076] like Figure 2 , Figure 11 and Figure 12 As shown, to improve heat dissipation, the heat dissipation unit 22 and the light-emitting unit 21 connected thereto constitute an integrated structure 20. Multiple integrated structures 20 are spaced apart along a first direction, forming a second heat dissipation channel 32 that runs vertically from the light-emitting side to the non-light-emitting side between adjacent integrated structures 20. When the light-emitting unit 21 is working, the airflow below flows through the second heat dissipation channel 32 to the top of the channel, and then flows into the central region of the heat dissipation unit 22 from its side, continuing upwards. This helps to remove heat from the center of the heat dissipation unit 22, improving the heat dissipation effect. For example, by extruding, independent heat dissipation units 22 are formed, and different heat dissipation units 22 are respectively installed on corresponding light-emitting units 21 to form multiple independent integrated structures 20. This not only facilitates heat dissipation but also prevents other light-emitting units 21 from interfering with the adjustment of the light-emitting unit 21 that requires adjustment of its light-emitting direction.

[0077] In this embodiment, multiple integrated structures 20 are independently arranged to form a second heat dissipation channel 32 between adjacent integrated structures 20. It should be noted that, for plant lights where there is no need to consider adjusting the light emission direction of the light-emitting unit 21 by rotation, multiple light-emitting units 21 can be spaced apart along the first direction, and a heat dissipation unit 22 can be provided for each of the multiple light-emitting units 21. A through hole is provided on the heat dissipation unit 22, and a second heat dissipation channel 32 is formed from the light-emitting side to the non-light-emitting side through the through hole and the interval between two adjacent light-emitting units 21.

[0078] Furthermore, to improve the heat dissipation effect of the light-emitting unit 21, the light-emitting component 2 is provided with a first heat dissipation channel 31 that runs from the light-emitting side to the non-light-emitting side on both sides of the light-emitting component 2 in the first direction between it and the lamp holder 1. By setting the first heat dissipation channel 31 and the second heat dissipation channel 32, the heat generated by the light-emitting unit 21 during operation can be simultaneously drawn out from the first heat dissipation channel 31 and the second heat dissipation channel 32 in the direction from bottom to top to form an upward airflow, which is beneficial for heat dissipation of the light-emitting unit 21.

[0079] Furthermore, such as Figure 7 , Figure 11 and Figure 12As shown, the plant light also includes an electronic control structure for controlling the operation of the light-emitting unit 21. This electronic control structure supplies power to the light-emitting unit 21 and controls its operation. The electronic control structure also generates heat during operation. To facilitate heat dissipation and extend its service life, the electronic control structure is installed on the lamp holder 1 and located within the first heat dissipation channel 31, with the electronic control structure and the light-emitting component 2 in a non-contact configuration. When the light-emitting unit 21 is operating, the rising airflow within the first heat dissipation channel 31 can carry away the heat generated by the electronic control structure, thus achieving heat dissipation. Furthermore, the non-contact configuration between the electronic control structure and the light-emitting component 2 effectively prevents the electronic control structure from overheating, ensuring its heat dissipation effect.

[0080] Since the lamp holder 1 has connecting components 4 on both sides in the second direction, in order to simplify the structure of the lamp holder 1 and facilitate the installation of the electronic control structure, the electronic control structure is installed on the inner side wall of the lamp holder 1 in the first direction. Specifically, the lamp holder 1 includes four side frames, which are connected end to end to form a rectangular frame. The four side frames are two first frames 11 that are spaced apart and opposite each other in the first direction, and two second frames 12 that are spaced apart and opposite each other in the second direction. The first frames 11 extend in the second direction, and the second frames 12 extend in the first direction. Each first frame 11 is connected to the two second frames 12 at both ends in the second direction to form a rectangular frame. Each second frame 12 is provided with a mounting base 42, and the first frame 11 is provided with a mounting groove with an opening facing the light-emitting component 2. The electronic control structure is located in the mounting groove and installed on the first frame 11 by fasteners.

[0081] For example, two electrical control structures are provided, referred to as the first electrical control structure 51 and the second electrical control structure 52, respectively. The first electrical control structure 51 supplies power to one of the three light-emitting units 21 and controls its operation. The second electrical control structure 52 supplies power to the other two light-emitting units 21 and controls their operation. The first electrical control structure 51 is located within one of the first heat dissipation channels 31 and installed on the first frame 11 forming the first heat dissipation channel 31. The first electrical control structure 51 is also located within the other first heat dissipation channel 31 and installed on the first frame 11 forming the first heat dissipation channel 31. In this embodiment, the light-emitting unit 21 is an LED light board, and the two electrical control structures are LED driver power supplies. It should be noted that the arrangement of the electrical control structures is not limited to the above arrangement; the number of electrical control structures can be determined according to the number of light-emitting units 21, the structure of the lamp holder 1, etc.

[0082] Optionally, both electronic control structures are elongated strips extending along the second direction, and are respectively mounted on the inner sidewall of the corresponding first frame 11; the first frame 11 is made of heat-dissipating material. This arrangement increases the contact area between the electronic control structure and the first frame 11, allowing the rising airflow within the first heat dissipation channel 31 to dissipate heat from the electronic control structure while simultaneously allowing some of the heat generated by the electronic control structure to be directly dissipated through the first frame 11, further improving the heat dissipation effect of the electronic control structure. For example, both first frames 11 are made of aluminum. For example, the two electronic control structures are respectively mounted to the corresponding first frame 11 using multiple fasteners.

[0083] Furthermore, such as Figure 14 As shown, both electronic control structures are connected to wires. To avoid messy wiring, the inner sidewall of the first frame 11 is provided with a wiring groove 111 to facilitate the placement of the wires connecting the two electronic control structures. Optionally, the inner sidewall of each first frame 11 is provided with two wiring grooves 111, which extend along the second direction and are spaced apart along the direction from the light-emitting side to the non-light-emitting side.

[0084] Furthermore, such as Figure 13 and Figure 14 As shown, two suspension parts 6 are connected to opposite sides of the lamp holder 1, allowing the lamp to be hung and installed by hooks. Exemplarily, the two suspension parts 6 are located at opposite ends of the lamp holder 1 in a second direction. Specifically, each suspension part 6 has a mounting ring 61 connected to both ends. The upper side of the first frame 11 has an inwardly folded flange 112, which is connected to the mounting ring 61 and the flange 112 by fasteners. Specifically, the fasteners are a connecting bolt 71 and a locking nut 72. The free end of the connecting bolt 71 passes through a mounting ring 61 and the flange 112 in sequence before being locked by the locking nut 72. The head of the connecting bolt 71 prevents the mounting ring 61 from detaching from its head, thus achieving the installation between the suspension part 6 and the first frame 11.

[0085] To facilitate the installation of the suspension part 6 onto the hook for the plant light, the suspension part 6 is rotatable relative to the lamp holder 1. Specifically, an elastic element 73, such as an elastic washer or spring fitted around the connecting bolt 71, is sandwiched between the head of the connecting bolt 71 and the mounting ring 61. The inner diameter of the mounting ring 61 is larger than the diameter of the connecting bolt 71, allowing the suspension part 6 to rotate at a small angle relative to the connecting bolt 71 when the plant light is installed. At the same time, to improve the stability of the suspended plant light, the elastic element 73 applies external force to the mounting ring 61 to press the mounting ring 61 against the flange 112.

[0086] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
