Abstract

The application discloses an improved system for the control of a plurality of light projectors each generating a beam suitable for entertainment lighting and each provided with means to vary a plurality of parameters of the beam and with means to conform capable of cooperating to produce a desired adjustment of the beam when provided with a corresponding desired parameter value. The improved system disclosed employs a plurality of local control systems, each with its own local short-term memory, and means are provided for entering desired parameter values, and for storing said values for each of a plurality of desired lighting effects in the short-term memory of the local control system, such that they are each associated with at least one second value which identifies the desired lighting effect. Each of the local control systems has at least one input, and will output a stored parameter value to the means to conform when the second value with which that stored parameter value is associated is provided at said input. A means for selecting, which is capable of producing a plurality of such second values identifying a desired lighting effect to be reproduced, is coupled to said inputs of a plurality of local control systems, preferably by means of a serial data link. Preferably one such local control system is provided for each controlled fixture or device.
