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 43):
The LED lighting device of  claim 32 , further comprising:\n a current conversion switch positioned between the resistor unit and the last switch for blocking the current, which flows through the switch circuit unit; and a current blocking control unit for controlling the current conversion switch, when an over-current flows through the switch circuit unit, to block the current flowing through the switch circuit unit.
