[0029] Reference Figures 1 to 3 The present invention provides a rotating and fixed lamp head device, which is illustrated in the following embodiment:

[0030] A rotating fixed lamp holder device includes a lamp post 100, a lamp fixture 200, and a lamp arm 300. The lamp post 100 is a conventional cylindrical street lamp post 100. The lamp fixture 200 has a first rotating shaft 210 and a second rotating shaft 220 machined on its two side housings, with the center lines of the two rotating shafts coinciding. The lamp arm 300 has an overall elongated structure, with one end serving as a fixed end for connecting to the lamp post 100 and the other end serving as a mounting end for mounting the lamp fixture 200.

[0031] The mounting end of the lamp arm 300 has a through mounting opening 310, and the lamp fixture 200 is installed in the mounting opening 310. A pivot slot 321 and a pivot mounting block 330 are provided on the inner wall of the mounting opening 310. In this embodiment, the inner wall of the mounting opening 310 also has a pivot rod 320, and the pivot slot 321 is located within the pivot rod 320. The pivot rod 320 and the pivot mounting block 330 are located on the same axis, which corresponds to the axis of the lamp fixture 200's pivot. During installation, the first pivot 210 on one side of the lamp fixture 200 is first inserted laterally into the pivot slot 321 at the mounting end of the lamp arm 300. Then, the second pivot 220 on the other side of the lamp fixture 200 is inserted into the pivot sleeve 340, and the pivot sleeve 340 is then fixed to the pivot mounting block 330. In this way, the lamp 200 is supported on the lamp arm 300 by the pivots on both sides and can rotate around the axis. To lock the lamp 200 at the desired angle, a first locking structure is provided between the second pivot 220 and the pivot sleeve 340 to fix their relative positions after the angle is adjusted. Furthermore, for a more secure angle fixation, a third locking structure is provided between the pivot rod 320 and the first pivot 210 to lock and fix the first pivot 210 and the second pivot 220 at both ends of the lamp 200.

[0032] Meanwhile, the fixed end of the lamp arm 300 is designed to be adjustable in height along the lamp post 100. By loosening or locking the connection mechanism between the fixed end and the lamp post 100, the height of the entire lamp head assembly can be flexibly adjusted, and in conjunction with the angle adjustment of the lamp fixture 200, it can adapt to different lighting needs. See details [link to relevant documentation]. Figure 3 Among them, (a) the height of the 100 light pole is 4-6 meters; applicable places are urban secondary roads, auxiliary roads, community roads, industrial parks, landscape lighting, tourist attractions, parks, villas, courtyards, green belts, squares, sidewalks and other outdoor lighting; (b) the height of the 100 light pole is 6-10 meters; applicable places are urban main roads, auxiliary roads, community roads and other outdoor main area lighting; (c) the height of the 100 light pole is 10-15 meters; applicable places are urban public squares, parking lots, docks, stadiums, airports and other outdoor large area main area lighting.

[0033] Furthermore, a mounting groove is provided on the rotating shaft mounting block 330. The rotating shaft sleeve 340 is nested and fixed within this mounting groove. This nesting structure can effectively prevent the rotating shaft sleeve 340 from rotating or loosening during use, ensuring the stability of the support point of the second rotating shaft 220, and making the rotation adjustment of the lamp 200 more stable and reliable.

[0034] The first locking structure includes a locking screw 350 and a locking hole. Specifically, a threaded hole is radially formed on the side wall of the rotating shaft sleeve 340 as the locking hole. After adjusting the lamp 200° angle, a locking screw 350 is screwed into the locking hole until the end of the screw tightly abuts against the cylindrical surface of the second rotating shaft 220 inserted into the rotating shaft sleeve 340. The rotating shaft is locked by the friction generated by the screw. The structure is simple and easy to operate. A similar structure can be used for the third locking structure.

[0035] Furthermore, the cross-section of the bushing 340 is preferably designed to be rectangular. Correspondingly, the mounting groove on the bushing mounting block 330 is also machined into a rectangular groove that matches the shape of the rectangular bushing 340. When the rectangular bushing 340 is inserted into the rectangular mounting groove, both are completely constrained in the circumferential direction, thereby completely avoiding the possibility of the bushing 340 rotating when the locking screw 350 is tightened, making the locking operation more effortless and effective.

[0036] Furthermore, the lamp arm 300 is designed as an arched structure that arches towards the lamp fixture 200. When the lamp arm 300 is installed on the lamp post 100, the plane where the free end of the lamp fixture 200 is mounted is higher than the plane where the fixed end of the lamp arm 300 is connected to the lamp post 100. This "raised head" posture not only makes the light projection of the lamp fixture 200 wider and avoids the lamp arm 300 itself from blocking the light, but also enhances the overall aesthetic appeal.

[0037] Furthermore, the arched structure can be composed of two parallel, upwardly arched support rods 301, and a transverse connecting rod 302 connecting the top ends of these two support rods 301. These two support rods 301 and the transverse connecting rod 302 together form the aforementioned mounting opening 310, with the transverse connecting rod 302 located at the free end of the lamp arm 300. The pivot slot 321 and pivot mounting block 330 can be mounted on these two support rods 301. This frame structure effectively reduces the overall weight of the lamp arm 300 while ensuring structural strength.

[0038] To further enhance the rigidity of the lamp arm 300, multiple transverse or diagonal reinforcing bars 303 are welded or fastened between the two parallel upper arch support rods 301. These reinforcing bars 303 form a truss structure, significantly improving the bending and torsional resistance of the lamp arm 300, enabling it to withstand greater weight of the lamp 200 and wind loads, making it particularly suitable for applications with long arm spans or in high-wind environments.

[0039] Furthermore, a fixing sleeve is provided at the fixed end of the lamp arm 300, which can be fitted onto the outside of the lamp post 100. A second locking structure is provided between the fixing sleeve and the lamp post 100. When it is necessary to adjust the height of the lamp arm 300, the second locking structure is loosened, allowing the fixing sleeve and the entire lamp arm 300 to slide up and down along the lamp post 100; after adjusting to the predetermined height, the second locking structure is tightened, thus firmly fixing the lamp arm 300 to the lamp post 100. Specifically, the second locking structure includes the fixing sleeve itself and a fixing bolt. A threaded through hole is formed on the side wall of the fixing sleeve. The fixing bolt passes through the threaded through hole. When it is necessary to lock, the fixing bolt is tightened so that its end directly abuts against the side wall surface of the lamp post 100, and the fixing sleeve and the lamp post 100 are relatively fixed through strong friction. This method has a simple structure and low cost.

[0040] Furthermore, a guide bevel is machined at the edge of the opening of the pivot slot 321. This bevel forms a flared opening that narrows from the outside in. When installing the first pivot 210, even if there is a slight misalignment, the guide bevel can guide the first pivot 210 to slide smoothly into the bottom of the slot, greatly reducing the installation difficulty and improving the installation efficiency, which is especially beneficial for high-altitude operations.

[0041] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
