摘要： A DC power source unit 37 is provided which boosts source voltage from a power source portion 36. A lighting circuit 38 is provided which supplies DC voltage to loads, the DC voltage being obtained by stepping down output current of the DC power source circuit 37. A control circuit 39 is provided which controls the lighting circuit 38 in accordance with at least either voltage or current of LEDs 25 and controls the DC power source unit 37 so that a ratio of output voltage to voltage of the LEDs 25 becomes a preset fixed ratio.

摘要： According to one embodiment, a luminaire includes a lighting circuit configured to light a light source with a power supply from the outside, an accumulated-lighting-time storing section configured to store accumulated lighting time of the light source, and a control circuit configured to control the lighting circuit in a set mode. The control circuit sets, if a pattern for turning on and off the power supply from the outside is a predetermined initial illuminance correction setting pattern, a mode in an initial illuminance correction mode for performing initial illuminance correction corresponding to the accumulated lighting time of the light source. The control circuit sets, if the pattern for turning on and off the power supply from the outside is a predetermined normal setting pattern, the mode in a normal mode for not performing the initial illuminance correction.
