摘要：
A lighting device includes: a plurality of DC power supply circuits. A plurality of light sources and switching units are connected to each of the DC power supply circuits, the switching units being configured to respectively switch electrical connection between the light sources and said each of the DC power supply circuits. A difference in rated voltage between any two light sources connected to one of the plurality of DC power supply circuits in common is smaller than a difference in rated voltage between two light sources respectively connected to different DC power supply circuits of the plurality of DC power supply circuits.
