<p>PROBLEM TO BE SOLVED: To suppress an inrush current with a little power loss in a floodlight including a light-emitting diode.SOLUTION: The floodlight includes an input part connectable to a commercial AC power source or a fluorescent lamp stabilizer. The floodlight includes: the light-emitting diode; a rectifier circuit which rectifies an AC voltage supplied from the input part and supplies a rectified voltage to the light-emitting diode; and a serial circuit of a DC impedance element and a capacitor connected at least either between rectification lines at an input side of the rectifier circuit or between rectification lines at an output side of the rectifier circuit.</p> |
