[0018] The utility model also has the following advantages:

[0019] The upper hemisphere is installed at the bottom end of the suspension rod, and the lower hemisphere is mounted on the upper hemisphere to form a spherical structure. The suspension rod is then passed through the upper spherical ring of the U-shaped frame from bottom to top, and the spherical structure is accommodated and adapted in the upper spherical ring from below. Finally, the lower spherical ring is mounted at the bottom of the upper spherical ring, thereby realizing the spherical movable installation of the spherical structure relative to the U-shaped frame. By applying force to the suspension rod or the U-shaped frame, the angle of the U-shaped frame relative to the suspension rod can be adjusted through the relative rotation of the spherical structure in the limited space, thereby adjusting the installation projection angle of the lamp head assembly below.

[0031] like Figure 3 and Figure 4 As shown, the structure of the spherical adjustment component 4 is: it includes an upper hemisphere 41 and a lower hemisphere 43 that are assembled together to form a spherical structure, and the upper hemisphere 41 is installed at the bottom end of the suspension rod 3; a circular hole that matches the diameter of the spherical structure is opened on the horizontal arm of the U-shaped frame 5, and an upper spherical ring 45 is formed by extending upward along the edge of the circular hole. A lower spherical ring 47 is installed on the bottom surface of the horizontal arm of the U-shaped frame 5, and the upper spherical ring 45 and the lower spherical ring 47 constitute a limiting space for accommodating the spherical structure.

[0032] In this embodiment, the upper hemisphere 41 is installed at the bottom end of the suspension rod 3, and the lower hemisphere 43 is mounted on the upper hemisphere 41 to form a spherical structure. The suspension rod 3 is then passed through the upper spherical ring 45 of the U-shaped frame 5 from bottom to top, and the spherical structure is accommodated and adapted in the upper spherical ring 45 from below. Finally, the lower spherical ring 47 is mounted on the bottom of the upper spherical ring 45, thereby realizing the spherical movable installation of the spherical structure relative to the U-shaped frame 5. By applying force to the suspension rod 3 or the U-shaped frame 5, the angle of the U-shaped frame 5 relative to the suspension rod 3 can be adjusted through the relative rotation of the spherical structure in the limited space, thereby adjusting the installation projection angle of the lamp head assembly 10 below.

[0033] In this embodiment, the top plate 1 may be a part of the steel frame structure of the roof, and the floodlight is mounted on the roof via the steel frame structure.

[0034] The vertical arms on both sides of the U-shaped frame 5 are fitted to the two sides of the lamp holder assembly 10 , and the external fasteners pass through the vertical arms from the outside to the inside and are locked to the sides of the lamp holder assembly 10 , thereby achieving fixed installation of the lamp holder assembly 10 at the bottom of the U-shaped frame 5 .

[0035] The upper hemisphere 41 and the lower hemisphere 43 are both shell structures, and the joint edges of the upper hemisphere 41 and the lower hemisphere 43 are locked and fixed to each other via internal and external threads.

[0036] In this embodiment, the spherical structure is composed of an upper hemisphere 41 and a lower hemisphere 43, which is easy to assemble. It is also convenient to install the upper hemisphere 41 at the bottom of the suspension rod 3 conveniently and reliably, and ensure the overall aesthetics after installation.

[0037] A lower bolt 42 is installed through the upper hemisphere 41 from bottom to top toward the bottom end of the suspension rod 3 , and an upper bolt 2 is installed through the top plate 1 from top to bottom toward the top end of the suspension rod 3 .

[0038] A through hole is provided at the top of the upper hemisphere 41 for the lower bolt 42 to pass through, and the wall surface of the upper hemisphere 41 along the circumference of the through hole is concave to form a sunken annular platform 411. Figure 5 As shown, the top surface of the sunken annular platform 411 constitutes a step surface that fits with the bottom end of the suspension rod 3, and the bottom surface of the sunken annular platform 411 constitutes a plane that fits with the gasket on the lower bolt 42.

[0039] In this embodiment, by providing the sunken annular platform 411 , reliable positioning of the top surface of the upper hemisphere 41 relative to the upper suspension rod 3 is achieved, and stable locking and fixing of the lower bolt 42 is also facilitated.

[0040] A gap of less than 1 mm is provided between the inner wall surface of the limiting space formed by the upper spherical ring 45 and the lower spherical ring 47 and the outer wall surface of the spherical structure, so that the spherical structure can smoothly and conveniently rotate relatively in the limiting space.

[0041] The upper portion of the lower spherical ring 47 extends outward along the circumferential edge to form an annular surface 471 , and the annular surface 471 is in contact with the inner top surface of the U-shaped frame 5 . The lower spherical ring 47 is fixed to the U-shaped frame 5 via a screw assembly 44 .

[0042] A second screw set 46 is installed through the upper spherical ring 45 from outside to inside along the circumferential direction, and the inner end of each screw in the second screw set 46 abuts against the outer wall surface of the upper hemisphere 41.

[0043] In this embodiment, the spherical structure is fixed relative to the U-shaped frame 5 by the inner ends of the screws in the second screw group 46 abutting against the outer wall of the spherical structure, or even by the inner ends of the screws being slightly embedded relative to the outer wall of the spherical structure.

[0044] In this embodiment, the upper hemisphere 41, the lower hemisphere 43, the U-shaped frame 5, and the lower spherical ring 47 can all be stamped parts, formed by stamping plates.

[0045] The installation method of the utility model floodlight is:

[0046] The upper hemisphere 41 is connected to the bottom end of the suspension rod 3 by a single lower bolt 42; the lower hemisphere 43 is fastened to the upper hemisphere 41 by a thread to form a spherical structure; the suspension rod 3 installed with the spherical structure is passed upward from the bottom of the U-shaped frame 5 so that the spherical structure is accommodated in the upper spherical ring 45; the lower spherical ring 47 is mounted on the U-shaped frame 5 from below to wrap the spherical structure from below; the screw group 1 44 is locked downward from the top surface of the U-shaped frame 5 to lock the lower spherical ring 47 on the U-shaped frame 5. After locking, there is a 1 mm gap between the internal spherical structure and the inner wall of the external spherical ring, and the spherical structure can roll freely inside; after adjusting the angle, the screw group 2 46 is used to lock and pass through the upper spherical ring 45 from the external side, so that each screw in the screw group 2 46 is tightened or even slightly embedded in the wall of the spherical structure, thereby realizing the adjustment and fixation of the direction of the lamp holder assembly 10.

[0047] The utility model can realize the deflection of the lower lamp head assembly in any XYZ direction through the relative rotation of the spherical structure inside the limited space, meet the adjustment requirements of various angles, so that the lamp head assembly can illuminate the required position, and can be universally adjusted to a certain extent, with good practicality.
