Abstract:
A flickerless LED driver device includes a transformer having a primary coil for receiving an alternating-current (AC) voltage, and a secondary coil for generating a first induced voltage induced from the primary coil; a secondary coil circuit for receiving the first induced voltage and applying a first direct-current (DC) voltage to an LED module; a current sensor for sensing a driving current flowing through the secondary coil circuit from the secondary coil; a current controller for receiving a signal about the driving current and generating a control signal for controlling an emission current flowing through the LED module; and a ripple attenuator connected to the LED module to receive a visual light communication (VLC) signal and the control signal, control an emission current corresponding to the VLC signal to flow through the LED module, and suppress ripple of the emission current.

Claim (Index 2):
The LED driver device according to  claim 1 , wherein the current sensor outputs a control voltage corresponding to the sensed driving current as the signal about the driving current and transmits the control voltage to the current controller, and\n wherein the current controller receives the control voltage and controls a magnitude of the control signal based on an increase or decrease of the control voltage.
