ABSTRACT:
As a result that a switching circuit switches between a first power source for supplying power when illuminating a light emitting diode and a second power source for supplying a predetermined bias to the light emitting diode, a reference signal output from a reference power source is compared with a leak current of an LED lighting device using the light emitting diode, a control signal is generated based on the comparison result, and a display means displays a leakage result when the leak current of the lighting device using the light emitting diode is higher than a reference value; a bias is set to a value, by which a current flowing to the light emitting diode can be ignored, and a leak current flowing to the lighting device using the light emitting diode is detected.
