PROBLEM TO BE SOLVED: To provide an LED lighting fixture capable of preventing LED from getting damaged even when being connected to a conventional fluorescent lamp fixture.SOLUTION: A control circuit 50 controls: a first determination processing to determine whether a first terminal and a second terminal are in an open state or a short state in a connector 21 and a connector 22 respectively; a second determination processing to determine whether a voltage across the first terminal and the second terminal is smaller than a reference voltage value in at least either one of the connectors 21 and 22; a switching processing to switch a switch 40 from an OFF state to an ON state when, in both of connectors 21 and 22, the first terminal and the second terminal are determined as in the short state in the first determination processing, and when, at least in either of the connectors 21 and 22, the voltage across the first terminal and the second terminal is determined as smaller than the reference voltage value in the second determination processing. |
