Abstract: 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. 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.

Abstract: A luminaire has a plurality of reflecting lamellae between side reflectors. The lamellae each have an outer edge, an inner surface facing away from the outer edge, and a plane of symmetry through the outer edge and the inner surface.

Abstract: A solid state light apparatus with a solar shielded heatsink ideally suited for traffic controls. The current state of the art solid state traffic signals utilize LED arrays encased in the existing plastic or metal traffic signal cases which were originally design for incandescent bulbs.

For 25% of all signals (those facing west), during the late afternoon sunset the lensing system will focused the sunlight directly on the LED die raising the die temperature an additional 20 C.
