A new transmission power-off brake mechanism for stage lights

Abstract

The present invention discloses a new transmission power-off brake mechanism for stage lights, and relates to the field of LED lighting technology. The present invention overcomes the problem that the existing display lamp barrel technology currently on the market has no motor transmission mechanism and can only rely on manual adjustment of the light output angle. When a sudden power outage occurs, the stage light cannot cope with the problem. The following scheme is proposed: it includes an arm, the bottom of the arm is rotatably connected to the bottom of the stage light, the side of the arm is rotatably connected to the head, the bottom of the stage light includes a racket sheet metal magnet assembly, and the outer side of the racket sheet metal magnet assembly is provided with a bottom gear, and the head includes a head main bracket. The arm and the head of the present invention can realize dynamic movement at different angles through a motor, a transmission gear and a belt, and can flexibly and accurately switch different irradiation angles of the light output, and illuminate different scenes with different lighting effects. When a power outage occurs, the brake mechanism opens instantly, tightly holds the motor shaft, and enables the arm or the head to stay in the instantaneous angle direction.

Description

The head rotation generally needs to be adjusted manually, and cannot be remotely controlled. The operation is cumbersome and difficult. There is no transmission motor, let alone a power-off brake mechanism. It is impossible to achieve power-off brake and stay at a certain angle. It needs to be powered on again for adjustment. If it is necessary to switch between different light output angles in different scenes, it is necessary to arrange more equipment with different angles in other locations. This makes the scene design and control programming more complicated for stage layout and stage design engineers, the equipment utilization rate is low, and the equipment cost and labor cost invested are high.
