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.
Claims23
A luminaire comprising:
- a luminaire head comprising one or more optical devices;
- a movement system mechanically coupled to the luminaire head and configured to rotate the luminaire head around an axis of rotation, the movement system comprising:
- a motor comprising a motor shaft having a first part extending from a first side of the motor, the first part of the motor shaft coupled via a first mechanical coupling to the luminaire head and configured to cause rotation of the luminaire head about the axis of rotation;
- a braking system coupled via a second mechanical coupling to the motor shaft and configured to inhibit rotation of the luminaire head;
- and
- a control system comprising a processor electrically coupled to the motor and the braking system, the control system configured to engage the braking system by:
- determining whether the motor is rotating;
- engaging the braking system when it is determined that the motor is not rotating;
- and
- removing power from the motor after engaging the braking system.
A luminaire comprising:
- a luminaire head comprising one or more optical devices;
- a movement system mechanically coupled to a first optical device of the one or more optical devices and configured to move the first optical device, the movement system comprising:
- a motor comprising a motor shaft having a first part extending from a first side of the motor, the first part of the motor shaft coupled via a first mechanical coupling to the first optical device and configured to cause motion of the first optical device;
- a braking system coupled via a second mechanical coupling to the motor shaft and configured to inhibit movement of the first optical device;
- and
- a control system comprising a processor electrically coupled to the motor and the braking system, the control system configured to engage the braking system by:
- determining whether the motor is rotating;
- engaging the braking system when it is determined that the motor is not rotating;
- and
- removing power from the motor after engaging the braking system.
A luminaire comprising:
- a luminaire head comprising one or more optical devices;

- a motor comprising a motor shaft having a first part extending from a first side of the motor, the first part of the motor shaft coupled via a first mechanical coupling to the luminaire mechanism and configured to cause motion of the luminaire mechanism;
- a braking system coupled via a second mechanical coupling to a shaft of the motor and configured to inhibit movement of the luminaire mechanism;
- and
- a control system comprising a processor electrically coupled to the motor, the braking system, and a non-volatile memory, the control system configured to engage the braking system by:
- determining whether the motor is rotating;
- and
- upon determining that the motor is not rotating:
- engaging the braking system;
- removing power from the motor after engaging the braking system;
- and
- storing in the non-volatile memory a current absolute position of the luminaire mechanism.
