<p><P>PROBLEM TO BE SOLVED: To provide a lighting control method in which the operator is not confused even if he failed in "pull-less" action. <P>SOLUTION: The lighting control method comprises an inverter circuit 2 for lighting a fluorescent lamp 3 and a safety lamp lighting circuit 5 for lighting a safety lamp 6, and furthermore comprises a "pull-less" action circuit 4 which detects existence of AC power supply 1 and sends a lighting/turning-off signal to the inverter circuit 2 and the safety lamp lighting circuit 5. The pull-less action circuit 4 produces a signal for lighting the safety lamp 6 for a certain time whenever the AC power supply 1 is cut off (including a short time cut-off) and sends the signal to the safety lamp lighting circuit 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
