[0002] In various lighting applications, the adjustment of the illumination angle of floodlights is crucial. Existing floodlights have several shortcomings in angle adjustment. Many traditional floodlights have limited angle adjustment ranges, failing to meet the all-around, multi-angle lighting needs of complex scenarios. For example, in lighting the exterior walls of large buildings, it is difficult to illuminate all areas that need to be highlighted. Moreover, the adjustment methods of some floodlights are cumbersome and complex, requiring multiple tools, making operation inconvenient and consuming a lot of time and effort. This seriously affects work efficiency in scenarios such as stage performances that require frequent adjustments to the light angle. Furthermore, existing floodlights have poor angle stability after adjustment, easily shifting due to external forces or their own vibrations, resulting in unstable lighting effects and an inability to consistently maintain ideal illumination. Therefore, a rotating angle floodlight is designed. Utility Model Content

The fixture rotation drive mechanism 3 consists of a fixture rotation drive motor assembly 14, a motor assembly connecting bracket 15, a linkage rod 16, a connecting pin 17, a eccentric rod 18, a push rod 19, and a push cylinder 20.

[0017] The working principle of this utility model: The use of this structure can be divided into two adjustment processes: pitch angle adjustment and rotation angle adjustment.
[0018] Pitch adjustment is relatively simple. It mainly uses the movable motor group 7 of the mounting platform to drive the movable gear 11, and then the fixed platform plate 8 connected to the movable gear 11 rotates around the side connecting shaft 22. During the rotation, the floodlight 1, the luminaire mounting platform 2, and the luminaire rotation drive mechanism 3 are integrated to achieve pitch rotation.
[0019] The rotation angle adjustment is relatively complex and can be divided into small-angle rotation adjustment and large-angle rotation adjustment. The main basis for small-angle and large-angle rotation adjustment is the length of the linkage rod 16 and the position of the lamp rotation drive motor assembly 14 on the convex slide rail 24. When the position of the lamp rotation drive motor assembly 14 on the convex slide rail 24 is close to or far from the position of the floodlight 1, because the length of the linkage rod 16 is fixed, the floodlight 1 will deflect at the angle of its central axis with the arc concave ring 23 as the limiting ring. When the position of the lamp rotation drive motor assembly 14 on the convex slide rail 24 is such that the distance between the linkage rod 16 and the eccentric rod 18 and the linkage rod connecting ear 12 is relatively fixed with the length of the linkage rod 16, the central axis angle of the floodlight 1 and the position of the fixed platform plate 8 can be made parallel. At this time, the illumination position of the floodlight 1 does not change regardless of whether the lamp rotation drive motor assembly 14 is driven or not.
[0020] When the pitch angle and the rotation angle are combined, different rotation angles can achieve different illumination effects.
[0021] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
