Document Type and Number:
WIPO Patent Application WO/2021/082233
Kind Code:
A1
Abstract:
Disclosed is a stage lamp with an unlockable brake electric motor, the stage lamp comprising a controlled component and a brake electric motor (200) driving the controlled component to move. The brake electric motor (200) comprises an electric motor unit (210) and a brake unit (220) braking the electric motor unit (210), and the brake electric motor (200) is a power-off locking electric motor. The stage lamp further comprises a controller (300), an auxiliary power supply (400) used for providing standby power for the brake unit (220), and an input unit (410) used for controlling the auxiliary power supply (400) to be powered on or powered off, and the electric motor unit (210) and the brake unit (220) are connected in parallel and are both electrically connected to the controller (300). After the stage lamp is powered off, the electric motor unit (210) is locked, such that the controlled component remains at an original position and is prevented from falling and being damaged; and after the stage lamp is disassembled, the auxiliary power supply (400) is controlled by the input unit (410) to supply power to the brake unit (220), such that unlocking of the controlled component is realized.
