1. An illumination apparatus, comprising:
a rectifier connected to an alternating current (AC) power source and configured to perform a full-wave rectification for an applied AC voltage, and configured to provide a rectified voltage which is full-wave rectified to a light emitting unit as a driving voltage, the light emitting unit comprising a first light emitting group to an n-th light emitting group, n being a positive integer of at least two, and configured to emit light by receiving the driving voltage from the rectifier; a control signal generator configured to generate a switch control signal for controlling a series and parallel connection relationship between the first light emitting group to the n-th light emitting group, and generate a current control signal for controlling a operation of a current controller according to a voltage level of the driving voltage; a switch unit configured to perform an on or off operation according to the switch control signal, to selectively transfer the driving voltage; and the current controller comprising a first driving current controller to an n-th driving current controller connected to the first light emitting group to the n-th light emitting group, respectively, the first driving current controller to the n-th driving current controller configured to be selectively activated and to control a magnitude of a driving current of a light emitting element according to the current control signal. |
