PURPOSE:To easily discriminate whether all filters mounted to a plurality of light sources connected to the same dimmer have the same color by providing a color detection means for receiving light from each light source in an illuminated zone via a filter and detecting the color of the received light. CONSTITUTION:A dimmer control device 1 performs dimming control for a plurality of dimmers D1 to Dn via a plurality of lines l1 to ln. Color sensors S1 and S2 are arranged in an illuminated zone irradiated with a plurality of light sources. A color detection circuit 23 discriminates the color of light received with the color sensors S1 and S2, according to output signals therefrom. An output signal from the color detection circuit 23 is inputted to a color data memory circuit 24 and saved as color data. This saved color data is read out by a color display circuit 25 as a display means, and color corresponding to a light source as lit is displayed. As a result, it becomes easy to know whether filters disposed at a plurality of light sources concurrently lit have the same color, according to the aforesaid display means. |
