Illumination system control installation - uses memory system to aid control of direction and intensity of light projectors

摘要

The control installation for an illumination system, regulates leveral projectors in intensity, direction, and by the interposition of coloured filters and shutters in the projector beams. Transmitters are used to change the intensity settings, and mechanical parameters such as shutter state and direction in accordance with values in a store, as instructed by the control unit. This has a timer for the programmed regulation of the control, and a switching system for reading the memory. The control has two sections which operate sequentially to control mechanical parameters and the intensity of the projectors.
