Abstract

A light control system operable by one hand for directing the movements of a luminaire rotatably movable to a plurality of liminaire positions about a Y-axis and an X-axis by a pan motor and a tilt motor, respectively. The control system includes a first disk rotatably mounted to a support panel and a second disk rototably mounted to the first disk at the axis of the first disk perpendicular to the first disk. Code markings such as code bars marked around the circumferential periphery of each disk are indexed to the desired movements of the luminaire by simultaneously processing signals from optical pickoffs for the first and second disks and transmitting the processed signals to the pan and tilt motors. The primary received signals are analog signals which are converted to digital signals. An operator knows the position of the luminaire by manual touch feedback relating to the positions of the first and second disks.
