摘要： A lighting system capable of providing automated focus assistance for a rotatable lighting fixture thereof. In one example, an independently rotatable distance-measurement device located in the same theater-stage or light-show environment as the rotatable lighting fixture operates to measure a distance to the projection surface and transmits the measurement to an electronic controller. The electronic controller uses the measurement and a suitable algorithm to determine a focus parameter value for the projection optics of the rotatable lighting fixture. The determined focus parameter value is encoded in a control signal, which is then used to command a motor to move the corresponding component of the projection optics, thereby bringing and/or keeping in focus a pertinent edge of the illuminated area on the projection surface. An example method for automated focus assistance supports cue stack programming, single shot focus assistance, and continuous focus assistance.

摘要： Moving light fixture and method for controlling the position of a moving light fixture. In one example, the moving light fixture includes a housing, light sources, a stepper motor, a magnetic position encoder, and an electronic controller. The stepper motor rotates the housing. The magnetic position encoder is configured to transmit a position signal indicating an angular position of the housing. The electronic controller determines the angular position of the housing based on the position signal. The electronic controller also determines a full step of the stepper motor based on the angular position of the housing, and a micro step of the stepper motor. The electronic controller also determines a current position of the moving light fixture based on the full step and the micro step. The electronic controller drives the stepper motor to move the moving light fixture from the current position to a target position.
