PROBLEM TO BE SOLVED: To provide a luminaire in which the structure of an operation part can be simplified.SOLUTION: A luminaire includes an operation part 21 which receives operation input indicating change in operation mode and operation input indicating an increase or decrease in operation parameter, a plurality of light source driving parts 111-113 which turn on electric light sources 101-103 respectively, and a control part 13 which controls the respective light source driving parts 111-113 so that the respective light sources 101-103 illuminate with pieces of luminous flux corresponding to the operation mode and operation parameter. In at least one operation mode, at least one of the light source driving parts 111-113 is controlled by the control part 13 so that the light sources 101-103 when the operation parameter has a maximum value or minimum value are different in illumination/non-illumination state from when the operation parameter has another value. |
