PURPOSE:To make an arbitrary illumination level memorizable freely by controlling an operational means output of a desired illumination load so as not to be given to a memory means. CONSTITUTION:In a light regulation device 10, a switch 8 is turned to a terminal betaside during a work such as a rehearsal so that only a switch out of switches S1 to Sn, corresponding to an illumination load on a seat, is turned on and that a illumination level is not memorized. At that time the illumination load on the seat is lighted by a manual operation. Next the switch 8 is turned to a terminal alpha side on a take of action so as to perform a normal reproducing operation. Selective memorization can be performed for individual illumination loads R1 to Rn. For example, only the illumination level on the seat can be freely memorized before or after the illumination level of the illumination load on the stage. |
