DISTURBANCE SENSING SYSTEM FOR AN AUTOMATED MOVING-MIRROR LUMINAIRE

A luminaire (100) includes a mirror (112), a motion assembly (200), and a control system (600). The mirror (112) controllably deflects a light beam emitted from the luminaire (100). The motion assembly (200) includes a motor (208), a magnet (206) mounted directly to a shaft of the motor, and a motio...

Beschreibung
Zusammenfassung:	A luminaire (100) includes a mirror (112), a motion assembly (200), and a control system (600). The mirror (112) controllably deflects a light beam emitted from the luminaire (100). The motion assembly (200) includes a motor (208), a magnet (206) mounted directly to a shaft of the motor, and a motion sensor system (202). The motor (208) rotates the mirror (112) about an axis of rotation (201). Rotation of the motor causes an equal change in rotation of the mirror. The magnet's center aligns with the shaft's axis of rotation and the magnet's magnetic pole is oriented orthogonally to the shaft's 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.
