Beschreibung
Zusammenfassung:	A lighting device includes: first and second power feed terminals between which a light source of a light source device is configured to be electrically connected; a power supply circuit having output ends electrically connected respectively to the first and second power feed terminals and configured to output a DC power across the first and second power feed terminals; a control circuit configured to control the power supply circuit; and at least one identifying terminal for identifying a rated current of a light source. The control circuit is configured to identify a rated current of a light source connected between the first and second power feed terminals by detecting whether the identifying terminal is in floating state or not, and to control the power supply circuit so as to supply a current corresponding to the identified rated current through the first and second power feed terminals.
