[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, the utility model proposes a splicing type focusing LED street lamp with adjustable brightness, including a lamp body a1, a lamp body b2 and a splicing structure. The lamp body a1 and the lamp body b2 are spliced ​​and installed up and down. The backs of the lamp bodies a1 and b2 are both provided with fixing seats 4. The lamp body b2 is provided with a plug-in block 3 below the fixing seat 4. The fixing seat 4 is provided with a splicing structure for cooperating with the plug-in block 3 to assemble the lamp body a1 and the lamp body b2. A mounting seat 5 is provided at the bottom of the lamp body a1, and a mounting hole 6 for assisting the lamp body a1 and its assembly is opened on the mounting seat 5.

[0026] Wherein, LED lamp beads are arranged in both the lamp body a1 and the lamp body b2.

[0027] like Figure 2 As shown, the back of the lamp body a1 and the lamp body b2 are provided with fan-shaped heat sinks 7 located on both sides of the fixing base 4, and the front sides of the lamp body a1 and the lamp body b2 are provided with heat dissipation grooves 8. The fan-shaped heat sinks 7 and the heat dissipation grooves 8 expand the contact area between the lamp body a1 and the lamp body b2 and the outside world, thereby improving its heat dissipation capacity.

[0028] like Figure 4As shown, the splicing structure includes a movable plate 9, a supporting spring 10, a limiter, a transverse bolt 11 and a manual component. A rectangular groove 12 is provided at the top of the inner side of the fixed seat 4. Two groups of movable plates 9 are provided, both of which are movably arranged on the left and right sides of the rectangular groove 12 through the supporting spring 10. A manual component for driving the two groups of movable plates 9 to move synchronously is also provided in the rectangular groove 12; transverse bolts 11 are provided in the middle of the opposite sides of the two groups of movable plates 9, and limiters for limiting their moving trajectories are provided at the four corners of the opposite sides of the two groups of movable plates 9.

[0029] One end of the support spring 10 is connected to the groove wall of the rectangular groove 12 , and the other end of the support spring 10 is connected to the moving plate 9 , so that the support spring 10 generates an elastic supporting force on the moving plate 9 .

[0030] like Figure 3 As shown, a socket 13 communicating with the rectangular groove 12 is provided at the top of the fixing seat 4, the plug-in block 3 is inserted through the rectangular groove 12 via the socket 13, and fixing holes 14 for the horizontal bolt 11 to pass through are provided on both sides of the plug-in block 3.

[0031] like Figure 4 As shown, the limiting member includes a guide telescopic rod 15, a fixed end of the guide telescopic rod 15 is connected to the groove wall of the rectangular groove 12, and a movable end of the guide telescopic rod 15 is connected to the movable plate 9, and the movement trajectory of the movable plate 9 is limited by the guide telescopic rod 15.

[0032] Embodiment 2

[0033] like Figure 1-Figure 4 As shown, the utility model proposes a spliced ​​focusing, brightness-adjustable LED street lamp. Based on the above embodiment, this embodiment also records in detail the specific components of the manual assembly and the matching method between the manual assembly and the movable plate 9.

[0034] like Figure 3 and Figure 4 As shown, the manual assembly includes a rotating shaft 16, a connecting disk 17, a handle 18 and a pull rod 19. The rotating shaft 16 is rotatably connected to the fixed seat 4, one end of which is connected to the handle 18, and the other end passes through the fixed seat 4 and is connected to the connecting disk 17 located in the rectangular groove 12. A pull rod 19 is rotatably arranged between the eccentric part of the side of the connecting disk 17 and the movable plate 9.

[0035] In summary, when the utility model is in use, when the lamp body a1 and the lamp body b2 need to be assembled, the handle 18 is manually turned, and the handle 18 drives the connecting plate 17 to rotate through the rotating shaft 16. During the rotation process, it drives the two movable plates 9 to move synchronously in opposite directions through the pull rod 19, so that the support spring 10 is squeezed during the movement, and the support spring 10 is elastically deformed during the squeezing process. Then, the plug-in block 3 at the bottom of the lamp body b2 is inserted into the rectangular groove 12 through the socket 13. Finally, the rotational force applied to the handle 18 is released. At this time, the support spring 10 drives the movable plate 9 to reset, so that the movable plate 9 drives the cross bolt 11 to insert into the fixing hole 14 opened on the plug-in block 3, thereby completing the splicing and assembly of the two, thereby improving the overall lighting brightness and focusing brightness, and the operation is simple and convenient.

[0036] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
