PURPOSE:To enhance the visual environment and improve the atmosphere by operating a specially devoted switch installed on an operational thermal unit, and thereby transferring a lighting fixture automatically from the continuous dimming condition to the lighting condition of any desired pattern set by a main operating board or operational terminal unit. CONSTITUTION:When a specially devoted switch 6 on an operational terminal unit 4 is pushed, a main operated board 1 receives a sendout signal from the terminal unit 4 to know that the switch 6 is operated, to deliver at first a continuous dimming trigger signal to a dimming terminal unit 3. This dimming terminal unit 3 makes dimming control of each lighting fixture 5 on the basis of this signal. If the switch 6 is continued turned on even though the lighting fixture concerned is dimmed to its lower limit of continuous dimming range, the main operating board 1 delivers signal to the dimming terminal unit 3 so that the lighting fixtures 5 are lighted according to the pattern previously set. Thus automatic transition is made from the continuously dimmed condition into specified pattern lighting. This enhances visual environment and improves the atmosphere. |
