Patent Images
1. An illumination device comprising:
- a light emitting unit; and
a lighting circuit, to which the light emitting unit is installed, for supplying an 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 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.
