Abstract
PURPOSE:To indicate the condition of each lighting load simply and in easy-to- grasp manner by directly sensing the current in each dimmed lighting fixture by the use of a current sensor, and performing display of the condition upon this information from sensing. CONSTITUTION:At each on/off terminal unit 5 the illuminating power is supplied to or shut off from a corresponding lighting fixture 11 on the basis of a stored schedule or operation of switches on a main operation board 1. On the other hand, dimming data is given to a signal producing terminal unit 7 from the main operation board 1, and on the basis of this dimming data, a dimming control signal is prepared and delivered to each dimmed lighting fixture 11. In case illumination control of each dimmed lighting fixture 11 is performed in this manner, a current sensor 13 senses the current of the illuminating power supplied to each lighting fixture 11. A transmitter/receiver 17 transmits the information pertaining to the current of illuminating power to, for ex., the main operation board 1 via a transmission line 3. This transmission can be displayed with its performance condition of each dimmed lighting fixture by LEDs or a CRT.
