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 44):
A light emitting diode (LED) lighting device, comprising:\n a rectifier circuit for receiving an input power from a power source unit and outputting a rectified power; an LED unit comprising a plurality of LED channels, the plurality of LED channels being connected in series and comprising a first LED channel, a second LED channel and a N th  LED channel, wherein each LED channel includes a front part and a rear part; a variable resistor; and a switch circuit unit comprising a plurality of switches, 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, and wherein variable resistor value of the variable resistor is decreased to make the plurality of switches to be operated greater and to increase the plurality of LED channels to be operated and then the lighting device becomes bright.
