Abstract:
The purpose of the present invention is to reduce heat generated through a switching IC circuit in order to protect a switching IC circuit by connecting a resistor to an LED unit in which a plurality of LEDs are connected so as to disperse heat in the resistor when a rated voltage or more is inputted. To this end, the LED lighting device comprises: a rectification circuit unit for receiving input power from a power source unit and outputting a rectified power; an LED unit having a plurality of LED channels connected in series and a resistor unit connected to the last end of the LED channels; a current sensing resistor; and a switch circuit unit comprising a plurality of switches, wherein an nth switch is connected to the rear end of an nth LED channel so as to control an operation of the nth LED channel and is controlled by a sum of a current of the nth switch and a current of an (n+1)th switch, which flows through the current sensing resistor.

Claim (Index 28):
A light emitting diode (LED) lighting device, comprising:\n a rectifier circuit unit for receiving input power from a power source unit and outputting a rectified power; a charge storage circuit unit, receiving power from the rectifier circuit unit, storing charges at a high voltage, and outputting the stored charges at low voltage; an LED unit having a plurality of LED channels connected in series;\n a dimming control unit comprising a variable resistor for controlling the current flowing through the LED unit to control dimming of the LED channel; and \n a switch circuit unit comprising a plurality of switches, \n wherein an N th  switch is connected to the rear end of an N th  LED channel so as to control an operation of the N th  LED channel, and is controlled by a sum of a current of the N th  switch and a current of an (N+1) th  switch, which flows through the variable resistor.
