The invention relates to a focusing structure of a digital spot light, a output end of a direct current motor of the focusing structure of a digital spot light is connected with a first focusing chain wheel, the first focusing chain wheel is connected with a second focusing chain wheel via chains, the second focusing chain wheel is eqiaxial with a tachometer gear and a focusing screw, the tachometer gear is meshed with a potentiometer wheel, and the potentiometer is eqiaxial and connected with the potentiometer wheel, the potentiometer is equipped with a potentiometer control plate, and a micro-switch is connected with the potentiometer control plate by controlling cables. A limiting stopper is fixedly disposed on an insulating board, an apical shaft is penetrated a limiting stopper sleeve, the front portion end of the apical shaft is fixedly equipped with a locating nail, and the rear end of the apical shaft is corresponding and adjacent with the micro-switch. The invention has the advantages that the focusing structure of a digital spot light employs two-level driven system to focus automatically, and a plurality of lights can be in synchronous focusing, the resolution of the focusing movement of the lights is smaller than 0.3 mm, the repeat locating precision is smaller than 0.1 mm, and the focusing length is 70 mm. The focusing structure of a digital spot light is adapted for focusing portions of all kinds of spot lights, and is instead of hand focusing.
Description
technical field [0001] The invention relates to the technical field of spotlight focusing, in particular to a digital spotlight focusing mechanism. It is suitable for the focusing part of a special stage lighting lamp used in large stadiums, theaters and various studios. Background technique [0002] At present, there are many kinds of professional lighting lamps used in large stadiums, theaters, and studios. In particular, the focusing part of the spotlight is manually adjusted on the spot, has no memory state, and has low repeat positioning accuracy. It is difficult to synchronize the focus of multiple lamps, which will affect the performance effect. Contents of the invention [0003] In view of the above shortcomings, the object of the present invention is to provide a digital spotlight focusing mechanism. It adopts a two-stage transmission system, the first stage is a permanent magnet DC motor and a multi-pole gear transmission reducer, and the second stage is a spr...
