PURPOSE:To obtain a proper illumination without requiring man's hand by measuring light flux of a lighting apparatus which is lighted in accordance with a time schedule, comparing this with a standard light flux memorized in a memory, and controlling for dimming if illumination is low. CONSTITUTION:A main panel 1 processes set data for an operation switch, a time scheduler, a program card, etc., and transmits on/off data and dimming data for lighting apparatus 61-6n. A dimming control terminal 2 transmits dimming data, and receives dimming data to form dimming control signals for controlling dimming for the apparatus 61-6n. An on/off control terminal 3 receives on/off control data and puts a power circuit 5 on/off. In this constitution, if the main panel 1 transmits on/off and dimming data based on settings of the time scheduler, the apparatus 61-6n get on/off, and are controlled to be dimmed continuously. |
