Abstract
A lighting apparatus including a light emitting diode connected to a dimmer configured to modulate an input AC voltage depending on a selected dimming level, a rectifier configured to full-wave rectify the modulated AC voltage output from the dimmer to generate and output a driving voltage, a driving module configured to receive the driving voltage of the rectifier to detect the selected dimming level, and select one of three driving modes of a stop mode, a resistance driving mode, and a sequential driving mode depending on the detected dimming level, and a plurality of light emitting diode groups configured to emit light depending on a control of the driving module.
