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

[0019] The present application discloses an LED floodlight with a structure that is easy to replace the light source. Figure 1-3, including a trough-shaped lamp body 1, a light source board 2, a light-transmitting board 3, a reflector 4 and a power supply assembly 5. The light source board 2 is detachably connected to the bottom of the trough of the trough-shaped lamp body 1. The light-transmitting board 3 covers the opening of the trough-shaped lamp body 1 and forms a relatively sealed accommodation space with the trough-shaped lamp body 1. A sealing gasket is provided around the opening of the trough-shaped lamp body 1. The reflector 4 is arranged in the accommodation space, one port is used to cover the light source board 2 therein, and the other port is in contact with the light-transmitting board 3. The power supply assembly 5 is arranged outside the trough-shaped lamp body 1 and transmits the trough-shaped lamp body 1 to the light source board 2. Electrical connection, the light source board 2 is circular, and three buckling parts 6 are provided on the side of the light source board 2 away from the lamp beads. The buckling part 6 includes a cylinder 61 and a frustum 62. The cylinder 61 is fixed on the light source board 2, and the frustum 62 is coaxially fixed to the end of the cylinder 61. The diameter of the frustum 62 is larger than the diameter of the cylinder 61. A card slot 7 is provided at the bottom of the groove of the groove-shaped lamp body 1 corresponding to the position of the buckling part 6. The card slot 7 includes a circular hole groove 71 and an arc groove 72 that are connected. The diameter of the circular hole groove 71 is larger than the diameter of the frustum 62, and the cylinder 61 is adapted to the arc groove 72.

[0020] A backstop is provided between the buckling portion 6 and the slot 7 . The backstop is a semicircular magnetic block 8 . The semicircular magnetic block 8 is fixed on the groove-shaped lamp body 1 , and the side of the round table 62 can be adsorbed in the semicircular magnetic block 8 .

[0021] Reference Figure 3 In order to ensure that the floodlight has a better heat dissipation effect, a plurality of heat dissipation fins 9 are provided on the outer wall of the groove-shaped lamp body 1.

[0022] Reference Figure 2-3 The power supply assembly 5 includes a cover and a driving power supply. The driving power supply is arranged in the cover. The cover is fixed to the groove-shaped lamp body 1 by screws. A threading hole is opened in the middle of the groove-shaped lamp body 1 corresponding to the position of the driving power supply.

[0023] The implementation principle of an LED floodlight with a structure that facilitates replacement of light sources in an embodiment of the present application is as follows:

[0024] When installing the light source board 2, it is only necessary to insert the buckle part 6 on the light source board 2 into the card slot 7 and rotate the light source board 2. The cylinder 61 in the buckle part 6 moves along the arc groove 72 until the round table 62 is attracted and fixed by the semicircular magnetic block 8, so that the light source board 2 can be easily fixed in the groove-shaped lamp body 1.

[0025] Similarly, when disassembling, it is only necessary to rotate the light source board 2 in the opposite direction. When the torque applied by the staff to the light source board 2 is greater than the suction force of the semicircular magnetic block 8, the light source board 2 can be twisted, and then the round table 62 can be separated from the round hole.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
