PROBLEM TO BE SOLVED: To save labor for confirmation of time by providing a lighting control means, which is connected with a light switch, lights a lighting equipment on receiving a lighting signal and maintains it on until a certain time passes since reception of an extinction signal, and then extinguishes it after the time interval passes, on receiving an extinction signal. SOLUTION: When a lighting control means 13 receives a lighting signal S3, it outputs a prescribed dim signal S5 to a dim control means 14, when it receives an extinction signal S4. The control means continues the output of the dim signal S5, until a certain time has passed since the reception of this extinction signal S4, then it outputs an extinction signal S6 after the time has passed. In this case, the dim signal S5 lights a lighting equipment 11 so that its brightness becomes 50% of the brightest output. Thus, user can save labor, because he has no need to continue the pushing a light switch 12e during the confirmation of time once and has need of only onetime pushing of the light switch 12e and release of it. |
