[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses an angle-adjustable lighting device. Figure 1-Figure 2 , including a fixed lamp frame 1, a supporting foot 2 is connected to the center of the bottom of the fixed lamp frame 1 by screws, and a plurality of mounting holes 6 are equidistantly provided inside the supporting foot 2, so as to facilitate fixing the supporting foot 2 to the ground or ceiling or a supporting rod, and a connecting frame 3 is welded on the top of the fixed lamp frame 1, auxiliary connecting frames 4 are provided on both sides of the connecting frame 3, and lighting lamps 5 are installed on the tops of the connecting frame 3 and the auxiliary connecting frame 4, and installation boxes 7 are connected to the insides of the connecting frame 3 and the auxiliary connecting frame 4 by screws, and the installation box 7 is a hollow structure, which is convenient for installing the illumination light board and wire wiring, and lamp holders 13 are welded on the tops of the connecting frame 3 and the auxiliary connecting frame 4, and the lighting lamp 5 is connected to the lamp holder 13 by screws, so as to facilitate the disassembly and assembly of the lighting lamp 5.

[0020] like Figure 2 As shown, at the center of the bottom of the two auxiliary connecting frames 4, a connecting arm 8 is fixed in an integral structure for supporting the bottom of the auxiliary connecting frame 4, and support arms 9 are provided on both sides of the outer wall of the fixed lamp frame 1, and a positioning plate 10 is fixed in an integral structure at one end of the support arm 9 close to the connecting arm 8, and the end of the support arm 9 away from the positioning plate 10 is connected to the outer wall of the fixed lamp frame 1 by screws, and the fixed inclination angle of the support arm 9 outside the fixed lamp frame 1 can be adjusted according to lighting requirements;

[0021] like Figure 3 As shown, the positioning plate 10 is set to be circular, and a plurality of fixing holes 11 are evenly distributed along the circumferential direction on the surface of the positioning plate 10, and fixing bolts 14 are arranged inside the fixing holes 11. A group of through holes are opened on the surface of the connecting arm 8, and the positioning plate 10 and the connecting arm 8 are connected by the fixing bolts 14, and a rotating shaft 12 is fixed at the center of the positioning plate 10;

[0022] The rotating shaft 12 is rotatably connected to the connecting arm 8. When the connecting arm 8 is rotated, the auxiliary connecting frame 4 will be driven to change its angle. At this time, the lighting lamp 5 will cooperate to adjust the angle. After adjustment, it can be fixed by the fixing bolt 14.

[0023] The implementation principle of an angle-adjustable lighting device in an embodiment of the present application is as follows: during daily use, the connecting frame 3 and the auxiliary connecting frame 4 are in a parallel state, and at this time, the three lighting lamps 5 are concentratedly illuminated. When the lighting angle needs to be changed, the auxiliary connecting frame 4 can be rotated to both sides. At this time, the connecting arm 8 cooperates with the rotating shaft 12 inside the positioning plate 10 to rotate. When adjusted to a suitable angle, the connecting arm 8 and the positioning plate 10 can be fixed by passing the fixing bolt 14 through the fixing hole 11, thereby completing the positioning of the lighting lamps 5 on both sides. The inclination angle of the supporting arm 9 outside the fixed lamp frame 1 can also be adjusted to further expand the range of the angle adjustment of the lighting lamp 5. The overall structure is simple and ingenious, and can be operated and used according to lighting needs. It can be subsequently fixed to the outdoor installation point through the supporting foot 2 to complete the overall installation.
