[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A multi-mode LED floodlight includes a housing 1, an LED light panel 2, a self-cleaning heat dissipation structure 3, and an adjustment module 4;

[0030] Two outer shells 1 are provided, and the two outer shells 1 are rotatably connected on one side; an adjustment module 4 for adjusting the relative position of the two outer shells 1 is installed on the two outer shells 1; a self-cleaning heat dissipation structure 3 is installed on the rear side of the outer shell 1.

[0031] like Figure 2 and Figure 3 As shown, the self-cleaning heat dissipation structure 3 includes a heat dissipation component 31 and a self-cleaning filter module 32. The heat dissipation component 31 is mounted on the outer shell 1, and the self-cleaning filter module 32 is mounted on the outer shell 1.

[0033] In this embodiment, when the multi-mode LED floodlight is working normally, the light emitted by the LED light panel 2 is scattered to the outside through the lens 11. During use, the air entering the heat dissipation assembly 31 is filtered by the self-cleaning filter module 32 to prevent dust and debris in the air from flowing into the heat dissipation assembly 31 and affecting heat dissipation. The heat dissipation assembly 31 removes the heat dissipated by the LED light panel 2 during use, allowing the LED light panel 2 to operate normally. During use, the relative position of the two outer shells 1 is adjusted by the adjustment module 4, so that the LED light panels 2 on the two outer shells 1 are on the same plane, making it a single-sided diffused light mode. The position between the two outer shells 1 is changed by the adjustment module 4, so that the LED light panels 2 on the two outer shells 1 are at a certain angle, making it a multi-sided diffused light mode. Thus, it can be adjusted to different usage modes according to the usage scenario and needs, improving its applicability.

[0034] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 2 and Figure 4 As shown, the adjustment module 4 includes a ball connector 41, an electric push rod 42, and a stabilizing assembly. A ball connector 41 is fixedly installed on the inner side of each of the two housings 1. One ball connector 41 is fixedly connected to the electric push rod 42, and the other ball connector 41 is fixedly connected to the output end of the electric push rod 42. Multiple sets of stabilizing assemblies are installed between the two housings 1.

[0035] The stabilizing component includes rotating links 43, with one end of the two rotating links 43 hinged together and the other end of the two rotating links 43 respectively rotatably connected to the two outer shells 1;

[0036] like Figures 2-5 As shown, the heat dissipation assembly 31 includes a heat dissipation module and an air outlet module. The heat dissipation module is mounted on the outer casing 1, and the air outlet module is mounted on the lower side of the outer casing 1.

[0037] The heat dissipation module includes heat dissipation fins 311 and a junction box 313. Heat dissipation fins 311 for dissipating heat from the LED light board 2 are fixedly installed inside the outer shell 1. Multiple ventilation holes 312 are evenly opened at the upper and lower ends of the outer shell 1. A junction box 313 is fixedly installed on the lower side of the outer shell 1. The interior of the outer shell 1 is connected to the junction box 313 through the ventilation holes 312 on the lower side.

[0038] The air outlet module includes a ventilation hose 314 and a fan 315. The ventilation hose 314 is fixedly connected to the two junction boxes 313 at the bottom of the two housings 1 respectively. The fan 315 is fixedly installed at the bottom of one junction box 313.

[0039] The self-cleaning filter module 32 includes a circulating filter module and a pressing module. The circulating filter module is installed on the rear cover 12, and the pressing module is installed inside the outer shell 1.

[0040] The circulating filter module includes a circulating filter screen 321, a rotating wheel 322, and a drive motor 323. Multiple rotating wheels 322 are rotatably mounted on the inner side of the rear cover 12, and the circulating filter screen 321 passes around the outer side of the rotating wheel 322. The drive motor 323 is fixedly mounted on the outer side of the rear cover 12, and the output end of the drive motor 323 is fixedly connected to one of the rotating wheels 322.

[0041] The pressing module includes a rotating frame 324, a spring 325, and a pressure roller 326. One end of the rotating frame 324 is rotatably mounted on the inner side of the outer casing 1, and the other end of the rotating frame 324 is rotatably mounted with a pressure roller 326 for pressing the circulating filter screen 321.

[0042] In this embodiment, when the self-cleaning heat dissipation structure 3 and the adjustment module 4 are working normally, heat exchange occurs between the heat dissipation fins 311 and the LED light board 2. The fan 315 drives airflow through the ventilation hose 314 and the manifold box 313, allowing air from outside the housing 1 to enter the interior of the housing 1 through the upper side of the ventilation hole 312, carrying away the heat from the heat dissipation fins 311. Then, the hot air flows through the lower ventilation hole 312 into the manifold box 313, and then the hot air in the manifold box 313 flows through the ventilation hose 314 into another manifold box 313 before being discharged by the fan 315, thus achieving a heat dissipation effect. During the heat dissipation process, when external air enters the housing 1 through the ventilation hole 312, the air passes through the circulating filter between the upper rotating wheels 322. Filter 321 to prevent air from entering the heat sink fins 311; after a period of use, drive motor 323 drives a rotating wheel 322 to rotate, thereby moving the circulating filter 321 until the circulating filter 321 moves between the rotating wheels 322 on the lower side, so that the rotating wheels 322 are aligned with the ventilation holes 312 on the lower side; as the air inside the housing 1 flows into the ventilation holes 312, it passes downward through the circulating filter 321, blowing out the dust and debris on the circulating filter 321 that has moved to the lower side, thus achieving self-cleaning of the circulating filter 321; electric push rod 42 is connected to the two housings 1 through ball joint connector 41, and the angle between the two housings 1 is adjusted by stretching or retracting the electric push rod 42, and the support of the two housings 1 is strengthened by multiple sets of rotating connecting rods 43.
