Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: a multi-directionally rotatable LED floodlight, including an irradiation main body 1, an angle adjustment assembly 2 and a rotating assembly 3. The angle adjustment assembly 2 is arranged at the lower end of the irradiation main body 1, and the angle adjustment assembly 2 includes an adjusting base 22. The rotating assembly 3 is arranged at the lower end of the adjusting base 22;

[0029] The rotating assembly 3 includes a rotating base 32. The rotating base 32 is fixed to the lower end of the adjusting base 22 by connecting bolts 221. A base housing 31 is provided on the outer side of the rotating base 32. An installation groove 322 is opened at the lower end of the rotating base 32. A pressure spring 34 is installed in the installation groove 322 through a bearing 33. The lower end of the base housing 31 is fixed to the installation base 4 by installation bolts 35. The lower end of the pressure spring 34 is located at the upper end of the installation base 4. The upper ends of both the rotating base 32 and the base housing 31 are inclined planes;

[0030] During use, the irradiation main body 1, as the main carrier of the light source, is responsible for emitting light for illumination; the angle adjustment assembly 2 allows the user to adjust the angle of the irradiation main body 1; the adjusting base 22, as the basic part of the angle adjustment assembly 2, connects the irradiation main body 1 and the rotating assembly 3. The rotating base 32 installs the pressure spring 34 through the bearing 33. The base housing 31 surrounds and protects the rotating base 32, and at the same time cooperates with the inclined plane of the rotating base 32. The installation groove 322 is used to install the bearing 33 and the pressure spring 34. The installation bolts 35 are used to fix the base housing 31 and the installation base 4.

[0031] A non-slip sleeve 321 is provided on the outer side of the inclined plane at the upper end of the rotating base 32. The non-slip sleeve 321 is made of rubber. When the pressure spring 34 rebounds without pressure and makes the inclined planes of the rotating base 32 and the base housing 31 fit tightly, the non-slip sleeve 321 can significantly increase the static friction force between the two. The rubber non-slip sleeve 321 has good elasticity and friction.

[0032] A limiting groove 323 is opened at the upper end of the rotating base 32. The adjusting base 22 is installed in the limiting groove 323. The adjusting base 22 is fixed to the rotating base 32 by connecting bolts 221. The limiting groove 323 provides an installation position for the adjusting base 22 and restricts its movement in the horizontal direction.

[0033] A hollow block 21 is installed at the upper end of the adjusting base 22 through a fixing bolt 23. A gasket 231 is provided inside the fixing bolt 23. The hollow block 21 is an intermediate connector. The irradiation main body 1 is installed on the adjusting base 22 through the fixing bolt 23, ensuring the firmness of the connection. The gasket 231 protects the threaded part of the bolt from wear and extends the service life of the bolt.

[0034] The irradiation main body 1 includes a housing 11. The housing 11 is fixed to the upper end of the hollow block 21. An LED light-emitting board 12 is installed inside the housing 11. The housing 11 is a protective shell for the LED light-emitting board 12. The LED light-emitting board 12 is the light source core of the floodlight, converting electrical energy into light energy.

[0035] A power cord 14 is provided at the rear side of the housing 11. The power cord 14 is connected to the LED light-emitting panel 12. The power cord 14 serves as a medium for power transmission, delivering the electrical energy provided by an external power source to the LED light-emitting panel 12 so that it can operate normally.

[0036] A heat sink 111 is fixed to the rear side of the housing 11. The heat sink 111 serves as a medium for heat conduction and heat radiation, effectively dissipating the heat generated by the LED light-emitting panel 12 during operation into the surrounding environment.

[0037] A front baffle 13 is provided at the front side of the housing 11. The front baffle 13 is arranged outside the LED light-emitting panel 12. The front baffle 13 is made of a transparent material. The front baffle 13 serves as a protective barrier for the LED light-emitting panel 12, preventing external objects from directly contacting the LED light-emitting panel 12 while maintaining the light transmittance.

[0038] Multiple groups of balls 41 are installed on the mounting base 4. The balls 41 correspond to the lower end of the rotating base 32. When the rotating base 32 is pressed down by an external force, the balls 41 serve as a rolling medium between the rotating base 32 and the mounting base 4, reducing the frictional resistance between the two and improving the smoothness and fluency of rotation.

[0039] As an embodiment of the present utility model: When rotating the LED floodlight, first press down the upper end of the rotating base 32. The upper ends of both the rotating base 32 and the base housing 31 are designed with inclined surfaces. When pressing down, the spring will be compressed, reducing the static friction between the rotating base 32 and the base housing 31, and the rotation resistance will also be reduced accordingly. When the rotating base 32 is pressed down by an external force, the balls 41 serve as a rolling medium between the rotating base 32 and the mounting base 4, reducing the frictional resistance between the two and improving the smoothness and fluency of rotation;

[0040] After rotating to the desired angle, release the downward pressure applied to the rotating base 32. The compression spring 34 will rebound, causing the inclined surfaces of the rotating base 32 and the base housing 31 to fit tightly. Through the action of the anti-slip sleeve 321, the floodlight is firmly locked at the selected angle; thus, the rotation use of the LED floodlight is completed.

[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0042] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
