In an operation device, a control unit is configured to be capable of receiving at least two operation patterns. A control unit keeps a switch off for a period of length corresponding to an operation pattern detected by a detecting unit. In a luminaire, when the length of a period in which a power level detected by a detecting unit falls is included in a first time range, a control unit stops power supply to a lighting unit while maintaining power supply to a communication unit. |
