When the user needs to adjust the irradiation direction in the left and right directions, the irradiation direction of the floodlight can be conveniently adjusted by rotating the base left and right.

[0003] The above-mentioned floodlight can realize pitch angle adjustment and left-right rotation adjustment, but the pitch angle adjustment and left-right rotation adjustment are two separate adjustment structures. When the pitch angle is to be adjusted, the light box is swung, and when the left-right angle is to be adjusted, the base is rotated. The overall structure is complex, the cost is high, and it is not convenient to move and rotate at any angle.

[0005] The above-mentioned floodlight can realize pitch angle adjustment and left and right rotation adjustment, but the pitch angle adjustment and left and right rotation adjustment are two separate adjustment structures. When the pitch angle is to be adjusted, it is adjusted through the vertical angle adjustment component, and when the left and right angle is to be adjusted, it is adjusted through the rotating disk. The overall structure is complicated, the cost is high, and it is not convenient to turn and rotate at any angle. Utility Model Content
