Abstract

PURPOSE:To make switching of illuminance or twinkling continuously and provide smooth delighting control by furnishing a signal control part which continuously reduces the dimming level commanded with a dimming control signal sent from a signal producing terminal unit in accordance with the sensing output of a daylight sensor for each dimmed lighting fixture or their group. CONSTITUTION:On the basis of the dimming data sent from a main operation board, a signal producing terminal unit 7 produces a PWM signal indicating the dimming level etc., by pulse width or a DC control signal representing the dimming level etc., by the voltage or current level, and the produced signal is transmitted to signal control parts 11 via a transmission line 9 as a dimming control signal. At each signal control part 11 a dimming signal is prepared from a dimming control signal thus entered and a control signal prepared on the basis of the output from a daylight sensor 15. Thereby the dimmed lighting fixture is controlled smoothly in response to the output from the daylight sensor 15, not to give dwellers any incomfortable sense.
