摘要
PROBLEM TO BE SOLVED: To perform original light dimming control even if light of a headlight comes in a light receiving part. ;SOLUTION: A control part 2 has a function for controlling a specified tunnel lighting part 4 in the case where a brightness signal continuously satisfies a specified condition during a specified standby time. For example, in the case where the brightness signal continuously shows a specified brightness value during the specified standby time, a control signal for lighting tunnel inside lighting is outputted, or a control signal for putting out light of a tunnel outside lighting is outputted. The specified brightness value is less than 100 cd/m2 and the standby time is 30-90 seconds.;COPYRIGHT: (C)2000,JPO
