PURPOSE:To make preheat dimming lightup without impairing the illumination effect by performing preheat dimming lightup only under specified conditions at a level necessary for the next scene when the current scene is to be changed. CONSTITUTION:An illuminated scene data memory 6 of a control device 4 stores the data of an illumination load circuit 1 to be lighted for each scene, the preheat dimming level data set for each circuit 1, and the data of the circuit 1 to be lighted at the next scene. The memory 6 also stores the preheat dimming prohibition data scene by scene and the lighting memory data set for each circuit 1. According to contents stored in the memory 6, the circuit 1 to be lighted at the next scene is preheat dim lighted under the conditions that no preheat dim lightup is prohibited when the circuit 1 lighted up at the current scene. This is performed by giving a level signal to a dimmer 2, and thereby preheat dim lighting can be performed without impairing the illumination effect. |
