Claim Text:
1. An illumination device comprising: a light emitting unit; and a lighting circuit, to which the light emitting unit is installed, for supplying a direct current (DC) output voltage to the light emitting unit, wherein the light emitting unit includes a light emitting element which is connected to output terminals of the lighting circuit and emits light by the DC output voltage supplied from the lighting circuit; and a current limiting unit which limits a current flowing into the light emitting element from the lighting circuit at the moment when the light emitting unit is installed to the lighting circuit; wherein the current limiting unit does not limit the current flowing into the light emitting element from the lighting circuit in a normal lighting mode; wherein the current flowing into the light emitting element at the moment when the light emitting unit is installed to the lighting circuit is smaller than a current flowing into the light emitting element in the normal lighting mode; and wherein the light emitting unit further includes a power terminal detachably connected to the lighting circuit.
