As shown in
The multiple lamp bodies 1 are disposed independently. The lamp bodies 1 can be moved towards or away from the connector 2 connected to the lamp bodies 1 to adjust the spacing between the two lamp bodies 1 located at two ends of the connector 2. The connector 2 and the lamp bodies 1 corresponding to the connector 2 can be locked by the locking connection structure 3. Therefore, not only can the requirements of various different sizes of tents, farms, and other use scenarios be met, but also the light can be more uniformly distributed. Compared with the related art, the lamp has the advantages of being simple in structure, small in volume, and convenient to transport and assemble.
Optionally, the locking connection structure 3 includes a connection hole 31, a long connection hole 32, and a locking member 33. The connection hole 31 is disposed in one of the connector 2 or the lamp body 1 corresponding to the connector 2. The long connection hole 32 is disposed in another one of the connector 2 or the lamp body 1 corresponding to the connector 2. The locking member 33 is inserted in the connection hole 31 and the long connection hole 32. The locking member 33 can be moved in the long connection hole 32 and can lock the connector 2 to the lamp body 1 corresponding to the connector 2 or unlock the connector 2 from the lamp body 1 corresponding to the connector 2. In this embodiment, the connection hole 31 is disposed in the lamp body 1, the long connection hole 32 is disposed in the connector 2, and the locking member 33 is a bolt and a nut. When the lamp body 1 is moved towards or away from the connector 2 connected to the lamp body 1 (at this time, the bolt is in a loose state), the bolt can be moved along the long connection hole 32, and the nut is slidably disposed in the long connection hole 32 and threadedly connected to the bolt. That is, the nut can only translate along the long connection hole 32 together with the bolt and cannot rotate. When the lamp body 1 is moved to a proper position, the connector 2 can be locked with the lamp body 1 corresponding to the connector 2 by tightening the bolt. In this embodiment, the locking connection structure 3 is simple in structure, convenient to operate, and small in volume so that the volume of the lamp cannot be increased.
In other embodiments, the locking connection structure 3 may be in other forms, as long as the lamp body 1 can be moved towards or away from the connector 2 connected to the lamp body 1, and the locking connection structure 3 can lock one end of the connector 2 to the lamp body 1 corresponding to the one end or unlock one end of the connector 2 from the lamp body 1 corresponding to the one end.
To increase the connection stability between the connector 2 and the lamp body 1 corresponding to the connector 2, the locking connection structure 3 further includes a receiving portion 34 and an insertion portion 35. The receiving portion 34 is disposed in one of the connector 2 or the lamp body 1 corresponding to the connector 2. The insertion portion 35 is disposed in another one of the connector 2 or the lamp body 1 corresponding to the connector 2. The insertion portion 35 can be inserted into or separated from the receiving portion 34. An insertion connection is used to facilitate assembly.
The receiving portion 34 includes multiple risers 341 disposed at intervals. Each of the multiple risers 341 is provided with an insertion hole 3411. The insertion portion 35 can be inserted into the insertion hole 3411 of at least one riser 341. The insertion portion 35 is provided with an elastic piece 351. The elastic piece 351 is configured to generate elastic deformation and prevent the insertion portion 35 from being pulled out from the insertion hole 3411. In this manner, the riser 341 can be clamped by the elastic piece 351 to reinforce the connection between the connector 2 and the lamp body 1. In the process in which the insertion portion 35 is inserted into the insertion hole 3411 of a riser 341 from one side of the riser 341, the elastic piece 351 is pressed by the inner wall of the insertion hole 3411 to generate elastic deformation so that the insertion portion 35 is smoothly inserted into the insertion hole 3411. After the insertion portion 35 is inserted into the insertion hole 3411, the elastic piece 351 can automatically reset and bounce up and abut another side of the riser 341 to prevent the insertion portion 35 from being pulled out from the insertion hole 3411.
In this embodiment, the insertion portion 35 is disposed on the connector 2, the receiving portion 34 is disposed on the lamp body 1 connected to the connector 2, and the multiple risers 341 are heat dissipation fins of the lamp body 1. For ease of description, along the direction from the edge of the lamp body 1 toward the center thereof, multiple heat dissipation fins are sequentially denoted as a first heat dissipation fin 34111, a second heat dissipation fin 34112 . . . a nth heat dissipation fin 3411n. When the insertion portion 35 is inserted into the insertion hole 3411 of the first heat dissipation fin 34111, the spacing between the two lamp bodies 1 located at two ends of the connector 2 is relatively large. When the insertion portion 35 is inserted into the insertion hole 3411 of the second heat dissipation fin 34112, compared with the case where the insertion portion 35 is inserted in the insertion hole 3411 of the first heat dissipation fin 34111, the spacing between the two lamp bodies 1 located at two ends of the connector 2 is slightly reduced. When the insertion portion 35 is inserted into the insertion hole 3411 of the nth heat dissipation fin 3411n, the spacing between the two lamp bodies 1 located at two ends of the connector 2 is the smallest.
Optionally, the receiving portion 34 further includes a stop block 342. Along the direction along which the insertion portion 35 is inserted into the insertion hole 3411, the stop block 342 is located behind the multiple risers 341. When the insertion portion 35 is inserted into the insertion hole 3411 of the riser 341 adjacent to the stop block 342, the insertion portion 35 can abut the stop block 342. In this embodiment, the stop block 342 is located behind the nth heat dissipation fin 3411n. The setting of the stop block 342 can prevent the insertion portion 35 from being excessively inserted into the insertion hole 3411 of the nth heat dissipation fin 3411n and avoid the phenomenon that the insertion portion 35 contacts with other structures of the lamp body 1, causing the lamp body 1 to be damaged.
Optionally, the connector 2 includes multiple connection parts 21 disposed in parallel and connected to each other. Two ends of each connection part 21 are connected to two lamp bodies 1 adjacent to the each connection part 21 by locking connection structures 3 in a one-to-one manner. In other words, one end of each connection part 21 is connected to the lamp body 1 corresponding to the one end by one locking connection structure 3. In this manner, a multi-point connection can be formed between the connector 2 and the lamp body 1 to ensure a more stable connection between the connector 2 and the lamp body 1.
In this embodiment, an extension part 22 is disposed between two adjacent connection parts 21. The two adjacent connection parts 21 are securely connected to two ends of the extension part 22 in a one-to-one manner. In other words, the two connection parts 21 connected to two ends of the extension part 22 and the extension part 22 have an H-shaped structure as a whole so that the stability of the connection between the connector 2 and the lamp body 1 can be improved. In other embodiments, the extension part 22 may not be disposed. Only two adjacent connection parts 21 need to cross each other and need to be securely connected to each other. In other words, two adjacent connection parts 21 have an X-shaped structure.
In this embodiment, multiple connectors 2 include first connectors 2a. Each first connector 2a includes two first connection portions 20a in a shape of a flat plate. The two first connection portions 20a are connected to two lamp bodies 1 adjacent to the two first connection portions 20a in a one-to-one manner. Two first connection portions 20a of the same first connector 2a are parallel to each other. The two first connection portions 20a of the same first connector 2a are located in the same plane. In other words, the first connector 2a is integrally in a shape of a flat plate so that the two lamp bodies 1 adjacent to the first connector 2a are located in the same plane. That is, after the installation of the lamp is completed, the height of the two lamp bodies 1 adjacent to the first connector 2a from the ground is the same so that the lamp provides a more uniform light.
In other embodiments, of the two first connection portions 20a of the same first connector 2a, one first connection portion 20a is located above another first connection portion 20a along the direction perpendicular to the first connection portions 20a. In other words, along the direction parallel to the first connection portions 20a, the first connector 2a has a Z-shaped structure when viewed from the side. After the installation of the lamp is completed, the height of the two lamp bodies 1 adjacent to the first connector 2a from the ground is different, for example, one high and one low, so that different light requirements can be met.
Optionally, multiple connectors 2 further include second connectors 2b. Each second connector 2b includes two second connection portions 20b in a shape of a flat plate. The two second connection portions 20b are connected to the two lamp bodies 1 adjacent to the two second connection portions 20b in a one-to-one manner. An included angle is formed between two second connection portions 20b of the same second connector 2b.
Exemplarily, the lamp body 1 is in a shape of a square. When the lamp includes five lamp bodies 1, one lamp body 1 is located in the middle. The remaining four lamp bodies 1 are connected to the four sides of the lamp body 1 in the middle by second connectors 2b in a one-to-one manner. In this manner, the light-emitting directions of the remaining four lamp bodies 1 can be converged towards the lamp body 1 in the middle so that the light of the five lamp bodies 1 can be concentrated, and the light intensity can be improved. In addition, the lamp may include three rows of lamp bodies 1 denoted as a first row of lamp bodies 1a, a second row of lamp bodies 1b, and a third row of lamp bodies 1c. Each row of lamp bodies 1 include multiple lamp bodies 1. The first row of lamp bodies 1a are located in the middle. The second row of lamp bodies 1b and the third row of lamp bodies 1c are located on two sides of the first row of lamp bodies 1a, respectively. In the first row of lamp bodies 1a, two adjacent lamp bodies 1 are connected by a first connector 2a. Similarly, in the second row of lamp bodies 1b, two adjacent lamp bodies 1 are connected by a first connector 2a. In the third row of lamp bodies 1c, two adjacent lamp bodies 1 are connected by a first connector 2a. Two adjacent lamp bodies 1 between the first row of lamp bodies 1a and the second row of lamp bodies 1b and two adjacent lamp bodies 1 between the first row of lamp bodies 1a and the third row of lamp bodies 1c are separately connected by a second connector 2b. Thus, the light-emitting directions of the second row of lamp bodies 1b and the third row of lamp bodies 1c are converged towards the first row of lamp bodies 1a so that the light of the three rows of lamp bodies 1 can be concentrated, and the light intensity can be improved. Of course, the lamp may be arranged in other forms or may be arranged according to scenario requirements. The arrangement mode is not limited herein.
