<p><P>PROBLEM TO BE SOLVED: To reduce the flicker of lighting by preventing reverse movement in the changing direction of a light control level even if a termination command is transmitted with a delay to a part of a plurality of receiving terminals. <P>SOLUTION: An operation input part 4 sets as a preset light-control level a product of a maximum transmission delay time as a maximum of a time from a transmission time of its own light-control terminal 1 when a transmission delay occurs at the transmission of a termination command through a signal wire 2 to a receiving time of the other light-control terminal 1 added to a time from a transmission time of a starting command to a scheduled transmission time of a termination command and a variation volume of light control levels per unit time, and information on the preset light control level is added to the termination command. On the other hand, after a starting command is inputted for the light control of each lighting load 3 to be started, a load control part 6 changes the control of each lighting load 3 from a light control level at the receiving of the termination command to the preset light-control level to finish the light control when the termination command is inputted from a communication part 5, and performs the control of constantly lighting at the preset light control level. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
