Power supply device, luminaire and power source system

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.

主权项

1. A power supply device comprising:
a power supply circuit configured to produce power to light a light source from power supplied from an external power supply; an accumulated-lighting-time storing section configured to store cumulative lighting time of the light source; and a control circuit configured to operate in an initial illuminance correction mode for performing initial illuminance correction based on the cumulative lighting time of the light source, when a pattern of turning on and off the power supplied from the external power supply is a predetermined initial illuminance correction setting pattern, and operate in a normal mode for not performing the initial illuminance correction when the pattern of turning on and off the power supplied from the external power supply is a predetermined normal setting pattern.
