A docking groove 111 is formed on each of the two lamp bodies 11; a first threaded hole 121 adapted to the tensioning member 13 is provided on the elastic connector 12; when the docking grooves 111 of the two lamp bodies 11 are docked, the two ends of the elastic connector 12 are respectively connected to the two lamp bodies 11, and the tensioning member 13 passes through the first threaded hole 121, so that by rotating the tensioning member 13, the tensioning member 13 is controlled to lift and tension the elastic connector 12 on the lamp body 11, so that the two docking grooves 111 are locked and connected to form an installation space for installing the light source.

[0039] In this embodiment, the lamp body assembly 1 is generally used for a linear lamp with a longer length. Two lamp bodies 11 are provided, and a docking groove 111 is formed in the lamp body 11. When the docking grooves 111 of the two lamp bodies 11 are docked and locked, the two docking grooves 111 are interconnected to form an installation space for installing a light source, so that the entire lamp body assembly 1 can meet the required length while reducing the length of a single lamp body 11, thereby reducing the manufacturing difficulty and manufacturing cost of the lamp body 11; an elastic connector 12 is provided, and when the docking grooves 111 of the two lamp bodies 11 are docked, the two ends of the elastic connector 12 are respectively connected to the two lamp bodies 11, so that the two lamp bodies 11 are preliminarily positioned and fixed, so that the subsequent Further locking; at the same time, by opening a first threaded hole 121 on the elastic connecting piece 12, and passing the tensioning piece 13 through the first threaded hole 121, the tensioning piece 13 is threadedly connected to the first threaded hole 121.

Tighten, and then pull the lamp body 11 at both ends toward the middle, so that the corresponding notches of the docking grooves 111 can fit more closely, reducing or even eliminating the gap between the two docking grooves 111; by arranging the tensioning member 13 on the protruding portion 122, a part of the tensioning member 13 can extend into between the protruding portion 122 and the lamp body 11 through the first threaded hole 121, so that the threaded connection position of the first threaded hole 121 and the tensioning member 13 is located in the middle of the tensioning member 13 instead of the end of the tensioning member 13, which can prevent the tensioning member 13 from loosening and falling off from the elastic connecting member 12.

[0044] Specifically, in some embodiments, the tensioning member 13 is a locking bolt, which is passed through the first threaded hole 121 , and the bottom of the locking bolt abuts against the lamp body 11 .

[0045] In this embodiment, the nut of the locking bolt is located on the side of the elastic connecting member 12 away from the lamp body 11, which is convenient for screwing the locking bolt in or out of the first threaded hole 121; the rod of the locking bolt is inserted into the first threaded hole 121, and when the locking bolt is screwed in, the bottom of the rod abuts against the lamp body 11, and the elastic connecting member 12 is reversely lifted and tightened, thereby locking the lamp bodies 11 on both sides to make the connection of the docking groove 111 tighter, with a simple structure and easy installation.

[0046] Optionally, the connection portion 123 may be connected to the lamp body 11 by welding, bolt connection, or the like.

[0048] In this embodiment, the connection parts 123 at both ends of the protrusion 122 are respectively fixedly connected to the two lamp bodies 11 by fixing bolts 14, which is convenient for disassembly and assembly. Generally speaking, the connection part 123 is provided with a second threaded hole 1231, and the connection part 123 is fixedly connected to the corresponding lamp body 11 by a fixing bolt 14; it is easy to understand that according to actual conditions, when the area of ​​the connection part 123 is large, multiple second threaded holes 1231 can be provided on the connection part 123, and the connection part 123 is fixedly connected to the connection part 123 by multiple fixing bolts 14, so that the connection between the connection part 123 and the lamp body 11 is more firmly connected.

[0049] Optionally, the elastic connector 12 and the tensioner 13 can be arranged on the side of the two lamp bodies 11 away from the installation space, that is, the elastic connector 12 and the tensioner 13 are arranged on the outside of the docking groove 111 of the two lamp bodies 11, and the elastic connector 12 is connected to the outside of the two lamp bodies 11; by arranging the elastic connector 12 and the tensioner 13 on the outside of the docking groove 111, the elastic connector 12 and the tensioner 13 will not interfere with the electrical components and various wiring harnesses in the docking groove 111, so that disassembly and assembly are convenient.

[0050] Optionally, in some embodiments, Figures 1 to 3 As shown, the elastic connecting member 12 is disposed in the installation space and connected to the inner walls of the two docking grooves 111 .

[0056] Specifically, when fastening the tensioning member 13 to multiple elastic connecting members 12, the same fastening process parameters (such as tightening torque) need to be used to make the multiple elastic connecting members 12 have the same pulling force on the two docking grooves 111, so that the force on the two docking grooves 111 is more uniform and the locking effect on the two docking grooves 111 is better.

[0057] Specifically, in some embodiments, Figures 1 to 3 As shown, there are two elastic connecting members 12 , and the two elastic connecting members 12 are axially symmetrically arranged about the center line of the docking groove 111 .
