Abstract
A multiparameter lighting fixture, which includes a locking system for pan and/or tilt, either of which may include a manual input device and an actuator. The locking systems for pan and tilt can be manually locked or unlocked by a technician using their respective manual input devices and automatically locked or unlocked by their respective actuators. A yoke of the multiparameter lighting fixture can be locked in more than one rotational position in relation to the base housing. In addition, the lamp housing of the multiparameter lighting fixture can be locked in more that one rotational position in relation to the yoke. The locking systems for pan or tilt can be automatically locked by an appropriate actuator in response to an electronic control system.
Claims51
