PURPOSE:To vary the lighting time of an illuminating load according to the needs of a user by providing a time data correcting part which adds or subtracts correction data to and from at least either of the set data of an evening time data setting part and the set data of a morning time data setting part. CONSTITUTION:A time data correcting part 7 adds or subtracts the correction data to and from a morning time and an evening time outputted by the evening time data setting part 1 and morning time data setting part 2. Consequently, when the time lighting the illuminating load is shortened so as to save electric power energy, the correction data is so set that the illuminating load is turned on at a time later than the evening time data and turned off at a time earlier than the morning time data. Further, when the time lighting the illuminating load is extended for prevention or crimes, the correction data is only so set that the illuminating load is turned on at a time earlier than the evening time data and turned off at a time later than the morning time data. |
