PURPOSE:To effectively product the lighting in time according to the progress on the stage by controlling dimming of lighting load through the operation of fade progress from the fade time stored in a memory on the basis of output level of a start operation device. CONSTITUTION:An output signal of a start button 28 is given to a processing circuit 1 from a bus 2 through an input port 29, and the circuit 1 operates the fade progression f1 with the lapse of time by the operation of pushing the button 28 corresponded to the scene. Hence, the formula is given as f1=T1/T2X100%, where T1 shows the elapsed time from a point of time operated the button 28 and T2 shows the fade time stored in a memory 7 corresponding to each scene. Also, the circuit 1 compares the fade progression f1 with an output level of a scene regeneration fader 25 which has been set corresponding to the scene and makes a larger value the actual fade progression f1, and works out an output level S0 of the scene through the operation. Thus, the operator can perform an effective lighting production in time according to the progress on the stage by operation of the start button 28. |
