LIGHTING CONTROL DEVICE

PURPOSE:To specify the controllable range of each operator and prevent the confusion of the work by constituting a device controlling individual lighting fixtures by voice signals used in a theater or a studio with microphones, a mixing circuit, a voice recognizing circuit, a location judging circuit, and a collating circuit. CONSTITUTION:When a control command by voice from an operator with microphones 1-1-1-n is fed to a voice recognizing circuit 5 via a mixing circuit 3, it is decoded and applied to one input of a collating circuit 9. The control command contains the number of the lighting channel, dimming level or the like, and the control signal fed to the circuit 9 contains the information indicating the number of objects to be controlled and control content. On the other hand, the control command fed to the microphones 1-1-1-n is branched and fed to a location judging circuit 7, input signal levels of the microphones are compared, the signal with the highest level is judged and applied to the other input of the circuit 9. The circuit 9 then identifies the operation range permitted for the operator, and the fixture within the range is operated.
