Japanese Patent JP3561961
Kind Code:
B2
Abstract:
PURPOSE:To provide a dimming device in which a dimming level is changed slowly to a desired level for reducing stress on a lighting load and facilitating correction of the dimming level during actual performance. CONSTITUTION:At an input part 10 of a dimming operation table 1, a channel to be setting-changed and a dimming level to be changed are inputted. A control part 13 changes the dimming level memorized in a memory part 11 of each channel based on the inputted dimming level. Dimming level data are formed every moment for changing the current dimming level into the desired dimming level in a set fade time to be transmitted to a dimmer 3 through an output part 12. The dimmer 3 fades brightness of a lighting load 4 by applying dimming control to the lighting load 4 based on the dimming level data set for its channel.
