[0002] LED floodlights, also known as spotlights, are lamps that provide a higher illumination on a designated illuminated surface than the surrounding environment. Typically, they can be aimed in any direction and are weather-independent. They are primarily used in large-scale mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Existing LED floodlights typically feature angle adjustment through a bolted connection between the bracket and the lamp body. However, prolonged relative rotation between the lamp body and bracket can easily loosen the threads, shortening the lifespan of the LED floodlight's angle adjustment feature.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that the terms "first," "second," and the like in this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the disclosure described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure.

[0023] See also Figures 1-2 In an embodiment of the present utility model, an LED floodlight comprises a lamp body 1 and a bracket 2, a fixing plate 3 is provided between the lamp body 1 and the bracket 2, a rotating hole 301 is provided on the fixing plate 3, a first through hole 101 is provided on the lamp body 1, a second through hole (not shown in the figure) is provided on the bracket 2, a pin 4 passes through the second through hole, the rotating hole 301 and the first through hole 101 in sequence to hinge the bracket 2, the fixing plate 3 and the lamp body 1, abutting plate 302 is provided on the fixing plate 3, the abutting plate 302 abuts against the lamp body 1 so that the fixing plate 3 rotates with the lamp body 1, a screw hole 201 is provided on the bracket 2, a locking bolt 5 is screwed in the screw hole 201, the locking bolt 5 is rotated, and the locking bolt 5 abuts against the fixing plate 3 to fix the fixing plate 3, thereby fixing the lamp body 1. Specifically, the pin shaft 4 limits the fixing plate 3 and the lamp body 1 to rotate only around the pin shaft 4, and the abutment plate 302 on the fixing plate 3 fits with at least one side of the lamp body 1, thereby achieving surface-to-surface abutment and fixation. When the lamp body 1 rotates, the fixing plate 3 must rotate with the lamp body 1. When adjusted to a suitable angle, the locking bolt 5 on the rotating bracket 2 is tightened so that the bottom of the locking bolt 5 abuts against the fixing plate 3 to limit the rotation of the fixing plate 3, and then the lamp body 1 is locked and fixed, thereby solving the problem of short service life of the angle adjustment function of the LED floodlight, and the fixing plate 3 is not integrally formed with the lamp body 1 or the bracket 2, so that the fixing plate 3 is removable and replaceable, further improving the service life of the LED floodlight. That is, after the angle adjustment function of the existing LED floodlight fails, the use scenario of the lamp body 1 is greatly reduced and difficult to repair. After the angle adjustment function of the LED floodlight provided by the embodiment of the utility model fails, it can be directly repaired and maintained by replacing the fixing plate 3.

[0024] Preferably, a rough surface 303 is provided at one end of the fixing plate 3 away from the lamp body 1 so that the locking bolt 5 abuts against the rough surface 303. Specifically, the friction coefficient between the locking bolt 5 and the fixing plate 3 is increased, thereby achieving a better abutting and fixing effect.

[0025] Optionally, the rough surface 303 is a pattern of grooves uniformly distributed in the circumferential direction, and the locking bolt 5 abuts against the grooves on the rough surface 303 so that the fixing plate 3 abuts and fixes the locking bolt 5 .

[0026] Optionally, the rough surface 303 may also be circumferentially uniformly distributed raised points, and the locking bolts 5 abut against the raised points on the rough surface 303 , so that the fixing plate 3 abuts and is fixed against the locking bolts 5 .

[0027] Preferably, the distance from the pin 4 to the edge of the fixing plate 3 is greater than the distance from the pin 4 to the locking bolt 5 , so that the locking bolt 5 can be fixed against the fixing plate 3 when the lamp body 1 is rotated to any angle.

[0028] As a preferred Figure 2 As shown, the lamp body 1 includes a rear shell 102 , to which a circuit board 6 is fixedly connected. A heat sink 7 is provided between the circuit board 6 and the rear shell 102 to dissipate heat from the circuit board 6 .

[0029] Preferably, the end of the heat sink 7 away from the circuit board 6 is in contact with the rear shell 102 through the spring 8, so that the heat sink 7 fits the circuit board 6, thereby achieving a better heat dissipation effect and preventing the lamp beads on the circuit board from being damaged by overheating due to long-term operation.

[0030] Preferably, a stud 601 is provided on the circuit board 6, and a column hole 701 matching the stud 601 is provided on the circuit board 6. The spring 8 is sleeved on the stud 601, one end of the spring 8 abuts against the heat sink 7, and the end of the spring 8 away from the heat sink 7 abuts against the rear shell 102.

[0031] The lamp body 1 of the present invention is connected to the bracket 2 by a pin shaft 4, and the fixing plate 3 is arranged between the lamp body 1 and the bracket 2. By rotating the locking bolt 5 screwed on the bracket 2, the locking bolt 5 fixes the fixing plate 3, thereby fixing the illumination angle of the lamp body 1, greatly improving the service life of the angle adjustment function of the LED floodlight, and having a simple structure and easy maintenance. In addition, by arranging a heat sink 7 abutting against the spring 8 on the circuit board 6, the heat dissipation effect of the circuit board 6 is improved, and the service life of the lamp body 1 is further improved.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
