[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An LED street lamp comprises a lamp pole and a lamp holder;

[0007] The lamp pole has a cantilever, and the lamp holder is fixedly connected to the cantilever via a connecting structure;

[0008] The connection structure comprises a fixing frame fixedly connected to the lamp holder, the fixing frame is fixedly connected to the movable frame by bolts, the fixing frame and the movable frame have the same structure, the fixing frame and the movable frame have an arc-shaped portion matched with the cantilever and ears protruding outwards on both sides of the arc-shaped portion, the ears are penetrated by holes, and the ears of the fixing frame and the movable frame are fixedly connected by bolts and nuts;

[0009] A limiting structure is also arranged between the cantilever and the lamp holder.

[0010] In this way, during installation, the lamp holder is limited by the limiting structure, the fixed frame is matched with the cantilever, and then the movable frame is matched with the cantilever, and the fixed frame and the movable frame are connected with bolts and nuts to complete the installation.

[0011] The limiting structure comprises a limiting ring installed in the cantilever, a limiting slot is provided at the outer end of the limiting ring, and a limiting block which can be plugged into and matched with the limiting slot is fixed to the lamp housing of the lamp holder opposite to the limiting slot.

[0012] The limiting ring and the cantilever are directly opposite to each other and are penetrated by limiting holes, and the limiting ring and the cantilever are connected by a limiting rod.

[0013] Wherein, the fixing frame and the lamp holder are integrally formed.

[0014] Wherein, an oblique brace is fixed between the cantilever and the lamp pole.

[0015] In summary, the LED street lamp has the advantages of being able to limit the installation position of the lamp holder, being easy to install and operate, and having a simple and reliable structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] like Figure 1-5 As shown, an LED street lamp comprises a lamp pole 1 and a lamp holder 2;

[0023] The lamp pole has a cantilever 3, and the lamp holder is fixedly connected to the cantilever via a connecting structure 4;

[0024] The connection structure comprises a fixing frame 5 fixedly connected to the lamp holder, the fixing frame is fixedly connected to a movable frame 6 by bolts, the fixing frame and the movable frame have the same structure, the fixing frame and the movable frame have an arc-shaped portion matched with the cantilever and ears protruding outwards on both sides of the arc-shaped portion, the ears are penetrated by holes, and the ears of the fixing frame and the movable frame are fixedly connected by bolts and nuts;

[0025] A limiting structure is also arranged between the cantilever and the lamp holder.

[0026] In this way, during installation, the lamp holder is limited by the limiting structure, the fixed frame is matched with the cantilever, and then the movable frame is matched with the cantilever, and the fixed frame and the movable frame are connected with bolts and nuts to complete the installation.

[0027] During implementation, the limiting structure includes a limiting ring 7 installed in the cantilever, a limiting notch 8 is provided at the outer end of the limiting ring, and a limiting block 9 which can be plugged into the limiting notch is fixed to the lamp housing of the lamp holder facing the limiting notch. The lamp holder faces the cantilever, the arc-shaped arm of the fixing frame fits the cantilever, the limiting block is inserted into the limiting notch, the position of the lamp holder is limited, and then the movable frame is connected to the fixing frame.

[0028] During implementation, the limiting ring and the cantilever are directly opposite to each other and are penetrated by a limiting hole 10, and the limiting ring and the cantilever are connected by a limiting rod 11. This facilitates the fast installation of the limiting ring in the cantilever.

[0029] During implementation, the fixing frame and the lamp holder are integrally formed, which is convenient for processing.

[0030] During implementation, a diagonal brace 12 is fixed between the cantilever and the lamp pole to improve the support strength.

[0031] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
