<P>PROBLEM TO BE SOLVED: To reduce electric power consumption even if a fan part is continuously driven without affecting a human body adversely, and even if the fan part is continuously driven by repeating turning-on and -off during driving of the fan part. <P>SOLUTION: This lighting system 1 with the fan provided with the fan part 2 and a lighting part 3 is provided with a control part 4 for repeating turning-on and -off alternately when the fan part 2 is driven. Consequently, since the fan part 2 gives strong or weak rhythm or generates wind intermittently by alternate repeating of turning-on and -off, it is possible to avoid a condition in which the human body is always exposed to wind and to suppress electric power consumption when the fan part 2 is off. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
