Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Example 1: As Figures 1 to 4 As shown, a floodlight includes a housing 1 and a bracket 2. A light-emitting component 3 is disposed inside the housing 1. The bracket 2 includes a base plate 21, with side arms 22 fixedly disposed on both sides of the base plate 21. The side arms 22 have round holes 23, strip holes 24, and fasteners 4. The fasteners 4 pass through the round holes 23 or strip holes 24 and connect to the housing 1. The light-emitting component 3 includes a lamp plate, a reflector, and a lampshade. The lamp plate has multiple LED beads arranged in a matrix. The light-emitting component 3 has a conventional structure and will not be described in detail here. The base plate 21 and the side arms 22 are integrally formed.

[0030] In this embodiment, the long axis of the strip hole 24 is parallel to the extension direction of the side arm 22, which helps to ensure the consistency of the overall strength of the side arm 22.

[0031] In this embodiment, the short axis of the strip hole 24 is equal to the diameter of the round hole 23 so as to be used with the same type of fastener 4.

[0032] In this embodiment, the circular hole 23 is located along the extension direction of the long axis of the strip hole 24, and the strip hole 24 is located between the circular hole 23 and the base plate 21. Furthermore, the circular hole 23 is located at the end of the side arm 22, the distance between the strip hole 24 and the circular hole 23 is L, and the half angle of the circular hole 23 is R, satisfying R < L < 2R. Under the premise of ensuring that the overall structural strength of the side arm 22 meets the requirements, the strip hole 24 is positioned as close as possible to the side of the circular hole 23, resulting in a more reasonable structural design.

[0033] Example 2: Figure 1 , Figure 2 and Figure 5 As shown, the rest of the parts are the same as in Embodiment 1. The difference is that the lamp housing 1 has a first through hole 11 on each side. There are two nuts 5 inside the lamp housing 1. The two nuts 5 correspond one-to-one with the two first through holes 11. The fastener 4 includes two first bolts 41 that correspond one-to-one with the two nuts 5. The first bolts 41 pass through the round hole 23 and the first through hole 11 and are threaded to the corresponding nuts 5. Alternatively, the first bolts 41 pass through the strip hole 24 and the first through hole 11 and are threaded to the corresponding nuts 5.

[0034] In this embodiment, a limiting member 6 for restricting the rotation of the nut 5 is provided on the inner sidewall of the lamp housing 1. The limiting member 6 includes two baffles 61. One side of the baffles 61 is fixedly connected to the inner sidewall of the lamp housing 1, and the other side of the two baffles 61 is connected through a top plate 62. A cavity for accommodating the nut 5 is formed between the inner sidewall of the lamp housing 1, the two baffles 61, and the top plate 62. A notch 621 is provided on the top plate 62, and the notch 621 is located in the extension direction of the axis of the first through hole 11. The baffles 61 contact the side of the nut 5 to prevent the nut 5 from rotating. The shank of the first bolt 41 can pass through the cavity and then through the notch 621, avoiding interference between the bolt and the top plate 62. The structural design is relatively reasonable. Furthermore, the baffles 61 and the top plate 62 are integrally formed with the lamp housing 1.

[0035] Example 3: Figure 1 , Figure 6 and Figure 7 As shown, the rest of the components are the same as in Embodiment 1, except that the base plate 21 has n supporting feet 7 rotatably mounted on the side away from the lamp housing 1, where n is an integer greater than or equal to 2. When stored, the supporting feet 7 are completely flush with the base plate 21. In use, the supporting feet 7 are rotated to form a cross shape with the base plate 21, such as a 90° angle between the supporting feet 7 and the base plate 21, increasing the contact area with the ground. Preferably, n is 2, and the two supporting feet 7 are symmetrically distributed left and right.

[0036] When the fastener 4 passes through the strip hole 24 and connects to the lamp housing 1, the center of gravity of the floodlight may shift significantly. By adding support feet 7, the stability of the support is improved, preventing the floodlight from tilting or shaking due to an unstable center of gravity during use.

[0037] In this embodiment, the support foot 7 has a second through hole 71 at its center, and the base plate 21 has n screw holes 211. The n screw holes 211 correspond one-to-one with the n second through holes 71. The second bolt (not shown in the figure) passes through the second through hole 71 and is threadedly connected to the corresponding screw hole 211.

[0038] Example 4: Figure 7 and Figure 8 As shown, the rest of the parts are the same as in Embodiment 3. The difference is that the support foot 7 is provided with an annular groove 72 surrounding the second through hole 71 on the side facing the base plate 21. n protruding rings 212 are fixedly provided on the base plate 21. The n protruding rings 212 correspond one-to-one with the n annular grooves 72 and extend into the corresponding annular grooves 72. The protruding rings 212 and the annular grooves 72 rotate to cooperate, which helps to improve the stability of the structure.

[0039] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
