<p>PROBLEM TO BE SOLVED: To stably turn on a floodlight including a light-emitting diode in contact with a fluorescent lamp inverter stabilizer.SOLUTION: The floodlight is connectable to a fluorescent lamp inverter stabilizer 5 and includes: a light-emitting diode 27; a rectifier circuit 24 which rectifies an AC current supplied from the fluorescent lamp inverter stabilizer 5 and supplies a rectified voltage to the light-emitting diode 27; and a voltage detection circuit 33 which does not make a current flow from the side of the fluorescent lamp inverter stabilizer 5 to the side of the rectifier circuit 24 in the case where a voltage applied from the fluorescent lamp inverter stabilizer 5 is lower than a predetermined voltage, and makes a current flow from the side of the fluorescent lamp inverter stabilizer 5 to the side of the rectifier circuit 24 when the voltage becomes equal to or higher than the predetermined voltage.</p> |
