a focusing method of a three-zoom movie and television lamp comprises the following steps:
s1, starting a driving motor (23), driving a moving plate (24) to move, driving the moving plate (24) to move when the moving plate (24) moves, driving a second ball screw nut (34) to move transversely under the action of an extension spring (33) when the moving plate (24) moves to one side of a gear (28), and simultaneously driving a gear (28) to rotate by driving a second ball screw (32) to rotate so as to further drive a mounting ball (29) to rotate, so that the imaging lamp (31) is rotated and angle adjustment is carried out; when the moving plate (24) moves towards one side of the driving motor (23), the connecting rod (27) drives the second ball screw nut (34) to move reversely, so that the imaging lamp (31) is driven to rotate reversely;
s2, rotating the manual adjusting screw (6) to drive the first screw (10) to rotate, when the first screw (10) rotates, enabling the installation pipe (8) to move under the action of the first threaded ring (9), when the installation pipe (8) moves, the first ball screw nut (11) moves along with the installation pipe (8), meanwhile, the first ball screw nut (11) does not rotate under the action of the installation pipe (8), so the first ball screw (12) can be driven to rotate, the rotating column (14) is driven to rotate through the first bevel gear (13) and the second bevel gear (15), when the rotating column (14) rotates forwards, the pull rope (16) is wound on the rotating column (14), the installation ring (18) is driven to move towards one side of the reflector (17), and the focal length between the convex lens (20) and the imaging lamp (31) is shortened, when the rotating column (14) rotates reversely, the rotating column (14) loses the limit on the pull rope (16), and the mounting ring (19) moves reversely under the action of the return spring (22), so that the focal length between the imaging lamp (31) and the convex lens (20) is lengthened;
s3, rotating the zoom rotor (35) to adjust the transverse position of the convex lens (20) and further adjust the focal length;
and S4, matching the three focusing modes according to actual needs.
