PURPOSE:To adjust luminance of a lighting load to be constant with easy operation by selecting conversion parts having different light adjusting properties for each of light adjusting output circuits and controlling the lighting load according to the light properties different in lighting loads. CONSTITUTION:When transmission control data is received in a light adjusting terminal apparatus 3 from a main operational board 1 through a transmission cable 2, the terminal apparatus 3 determines the kind of the lighting appliances 5 based on the load king selection designating data, reads out or computes the light adjusting output from a data table 3 of a light adjusting property conversing means 14, a light adjusting signal is produced by a light adjusting signal producing means 15, and the signal is put out by a light adjusting signal output means 16. Consequently, even if the properties of appliances 14 are different, the light adjusting properties are made same and luminance is easily made constant. |
