Patent number: 10794571Abstract: A luminaire includes a mirror, a motion assembly, and a control system. The mirror controllably deflects a light beam emitted from the luminaire. The motion assembly includes a motor, a magnet mounted directly to a shaft of the motor, and a motion sensor system. The motor rotates the mirror about an axis of rotation.

The motion sensor system produces an output signal representing an absolute rotational position of the magnet. The control system stores an expected rotational position of the motor and determines whether the motion sensor system's output signal matches the stored position. When the output signal does not match the stored position, the control system rotates the motor position where the output signal matches the stored position.Type: GrantFiled: July 22, 2019Date of Patent: October 6, 2020Assignee: Robe Lighting s.r.o.Inventors: Jindrich Vavrik, Tomas Micunek, Josef Valchar
