Abstract: A light fixture including a housing, a light source, a framing shutter system, and an electronic processor. The electronic processor is connected to the light source and the framing shutter system. The electronic processor is configured to determine a desired orientation of a framing shutter blade, determine whether the desired orientation is within a set of physically possible positions of the framing shutter blade, determine an adjusted orientation of the framing shutter blade, wherein the adjusted orientation is based on the desired orientation, the adjusted orientation of the framing shutter blade corresponding to an orientation for the framing shutter blade that is included in the set of physically possible positions, and control the plurality of framing shutter motors to move the framing shutter blade to the adjusted orientation.

Abstract: A light fixture including a housing, a light source, a framing shutter system, and an electronic processor. The framing shutter system includes a framing shutter gate, a framing shutter blade, and a plurality of framing shutter motors. The electronic processor is connected to the light source and the framing shutter system. The electronic processor is configured to determine a desired orientation of the framing shutter blade, determine whether the desired orientation is within a gamut of the framing shutter blade, determine, in response to the desired orientation being outside of the gamut of the framing shutter blade, an adjusted orientation of the framing shutter blade, the adjusted orientation of the framing shutter blade corresponding to an orientation for the framing shutter blade that is as close as possible to the desired orientation, and control the plurality of framing shutter motors to move the framing shutter blade to the adjusted orientation.

Abstract: A lighting system capable of providing automated focus assistance for a moving lighting fixture thereof. In one example, a distance-measurement device connected to the moving 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. 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.

Abstract: 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.
