<P>PROBLEM TO BE SOLVED: To solve a problem that, in a conventional dimmer for stage use of this kind, setting of brightness of maximum 256 steps and control of 512 lamps are possible, and it takes time to distribute the data per one channel and flickering is felt when controlling a LED lamp or the like. <P>SOLUTION: In this light control method, the dimmer receives a signal corresponding to itself out of a light control signal from a light control table which nearly periodically transmits the light control data of multi-channels by communication and caries out light control. The receiving side has a receiver side light control means which estimates beforehand the time until receiving the light control data by next communication and performs light control step by step to a light control value estimated within the time. <P>COPYRIGHT: (C)2009,JPO&INPIT |
