[0030] Specifically, Figure 1-Figure 6 As shown, the heat sink 5 includes a heat sink substrate 52 arranged in the lamp frame 4 , a heat sink 51 is arranged on one side of the heat sink substrate 52 , and the heat sink 51 is located outside the lamp frame 4 , and one side of the heat sink substrate 52 contacts the LED lamp board 9 .

[0031] When in use, the floodlight can be fixed at the place of use through the base 1, and then the power supply 8 is installed in the power supply box 2, so that the LED light board 9 is powered by the power supply 8, so that the LED light board 9 emits light, and then the light is projected through the lampshade 6 to realize the illumination of the place of use. During the use of the floodlight, the LED light board 9 is cooled by the heat dissipation substrate 52 and the heat sink 51, which is conducive to preventing the LED light board 9 from being damaged by high temperature, so as to ensure the normal use of the LED light board 9;

[0032] At the same time, during use, the height of the floodlight can be adjusted according to usage requirements, and the specific adjustment steps are as follows:

[0033] The upper and lower support plates 31 are then screwed together to fix the upper and lower support plates 31, and the upper and lower support plates 32 are then screwed together to fix the upper and lower support plates 31.

[0034] Furthermore, if Figure 3 and Figure 7 As shown, limiting grooves 36 are provided on both sides of the extension plate 34 , limiting strips 35 are installed on both sides of the inner cavity, and the limiting strips 35 are slidably connected to the limiting grooves 36 .

[0035] When the extension plate 34 moves along the inner cavity of the lower support plate 31, the limiting strip 35 can slide along the limiting groove 36 to limit the extension plate 34 and the lower support plate 31, which is beneficial to the stable movement of the extension plate 34 and convenient for the telescopic adjustment of the support frame 3.

[0036] In addition, in one embodiment, if Figure 1-Figure 6 As shown, the lamp frame 4 is also provided with a locking structure 7 for facilitating the disassembly and assembly of the heat sink 5, and the locking structure 7 includes connecting blocks 72 fixed on both sides of the heat dissipation substrate 52, and a connecting groove for inserting the connecting block 72 is opened on one side of the lamp frame 4, and locking screws 71 are screwed on both sides of the lamp frame 4, and the connecting block 72 has a screw hole that matches the locking screw 71.

[0037] Furthermore, if Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, a snap-fit ​​component is provided between the heat sink 51 and the heat sink substrate 52, and the snap-fit ​​component includes a plurality of ridges 56 installed on one side of the heat sink 51, and a plurality of plug-in slots 54 opened on one side of the heat sink substrate 52, a plug-in board 57 inserted into the plug-in slot 54 is fixed at one end of the ridge 56, and a slot 53 connected to the plug-in slot 54 is also opened on one side of the heat sink substrate 52, and the ridge 56 is inserted into the slot 53.

[0038] When the heat sink 51 needs maintenance, the locking screw 71 can be screwed out of the screw hole, and then the heat sink 51 can be pulled to move the connecting block 72 out of the connecting groove until the heat sink substrate 52 is moved out of the lamp frame 4. Then, the heat sink 51 is pulled upward to move the convex strip 56 along the notch 53 and drive the plug-in board 57 to move along the plug-in groove 54 until the plug-in board 57 is moved out of the plug-in groove 54. In this way, the heat sink 51 is separated from the heat sink substrate 52, and the heat sink 51 is disassembled. Then, the heat sink 51 can be maintained or replaced. After maintenance or replacement, the heat sink 51 can be plugged into the heat sink substrate 52 through the cooperation of the convex strip 56 and the notch 53 as well as the plug-in plate 57 and the plug-in slot 54 to complete the installation between the heat sink 51 and the heat sink substrate 52, and then the heat sink substrate 52 is inserted into the lamp frame 4 through the connecting block 72 and the connecting slot, and then the locking screw 71 is screwed into the screw hole to fix the heat sink substrate 52 and the lamp frame 4, thereby realizing rapid disassembly and assembly of the heat sink 51, facilitating the maintenance or replacement of the heat sink 51, and helping to ensure the heat dissipation effect of the heat sink 5.

[0040] When the plug-in board 57 moves along the plug-in slot 54, the second clamping portion 58 moves along the first clamping slot, and the first clamping portion 55 moves along the second clamping slot to limit the position between the plug-in board 57 and the plug-in slot 54. At the same time, when the plug-in board 57 and the plug-in slot 54 are inserted and fixed, the first clamping portion 55 and the second clamping portion 58 are interlocked with each other under the action of the first clamping slot and the second clamping slot to increase the stability of the connection between the plug-in board 57 and the plug-in slot 54, which is beneficial to the stable installation between the heat sink 51 and the heat dissipation substrate 52, and further facilitates the stable use of the heat sink 5.
