  • Publication number: 20250207761
    Abstract: A luminaire includes a light source configured to generate an emitted light beam, and a beam reducer configured to move between a first position and a second position. In the first position, the beam reducer is outside the emitted light beam, and in the second position, the beam reducer receives the emitted light beam and occludes an outer portion of the emitted light beam to emit a reduced light beam having a smaller beam angle than the emitted light beam. The luminaire also includes an imaging subsystem configured to receive (i) the emitted light beam when the beam reducer is in the first position and (ii) the reduced light beam when the beam reducer is in the second position. The beam reducer is configured to move to the second position in response to a position of the imaging subsystem.

  • Publication number: 20240410559
    Abstract: A luminaire includes an enclosure, an air valve, and a control system. The enclosure includes a light source, an air pressure sensor, a temperature sensor and a first opening and is otherwise sealed from external air. The enclosure may include components that modify and emit a light beam. The air valve is coupled at a second opening to the enclosure and includes a membrane covering a third opening. The membrane reduces the passage of water droplets in air passing therethrough. The air valve blocks air passage between the enclosure and the membrane when closed and allows air passage when open. The control system determines whether the enclosure is adequately sealed based on air pressure as sensed by the air pressure sensor and a temperature as sensed by the temperature sensor.

  • Patent number: 12085267
    Abstract: A luminaire includes an enclosure, an air valve, and a chamber. The enclosure includes a sealed cover and light beam emitting components. The air valve is air coupled between the enclosure and the chamber. The chamber includes a drying agent and has an opening with a membrane completely covering the opening. The membrane passes air while reducing the passage of water droplets in the air. The air valve blocks air passage between the enclosure and the chamber when closed. A method for testing to determine adequate sealing of an enclosure of a luminaire includes closing an air valve to seal the enclosure from outside air, activating a heat-generating component, determining whether an air pressure in the enclosure increases by more than a threshold value, and sending a signal indicating a result of the determination. The method includes deactivating the heat-generating component and opening the air valve.

  • Patent number: 11774075
    Abstract: A luminaire includes a luminaire mechanism, a stepper motor, an absolute multi-turn rotational position sensing system, and a control system. The stepper motor moves the luminaire mechanism. The absolute multi-turn rotational position sensing system includes absolute rotational sensors that detect absolute positions of a cam indexer on the motor shaft and an indexer wheel coupled to the cam indexer. The indexer wheel rotates by a predetermined amount in response to one full rotation of the cam indexer. The control system determines an absolute position of the luminaire mechanism based on information from the absolute rotational sensors relating to the positions of the cam indexer and the indexer wheel. The control system receives a commanded position for the luminaire mechanism and causes the stepper motor to move the luminaire mechanism to the commanded position based on the absolute position of the luminaire mechanism.

  • Patent number: 11703213
    Abstract: A luminaire is provided that includes a head, a movement system, and a control system. The movement system rotates the luminaire head around an axis of rotation. The movement system includes a motor and a braking system. The motor moves a luminaire mechanism. The luminaire mechanism may be a gobo wheel, a lens, or other optical device of the luminaire, or it may be the luminaire head or the luminaire yoke. The control system determines whether the motor is rotating and engages the braking system when the motor is not rotating. When the motor is stopped, the control system may store in non-volatile memory a current absolute position of the luminaire mechanism.

  • Patent number: 11428384
    Abstract: A luminaire includes a white light LED light source emitting a light beam that that is filtered by first and second color filters. An optical device modifies the filtered light beam. A control system receives a commanded value for the optical device and responds by causing the optical device to move based on the commanded value; determining a Duv change in the light beam caused by the optical device; determining positions for the color filters based on the Duv change, a current correlated color temperature (CCT) isotherm value, and a current Duv value; and moving the color filters to their determined positions. The control system may alternatively receive a command with a Duv value and respond by determining color filters positions based on the received Duv value and a current CCT isotherm value; and moving the color filters to their determined positions.
