摘要： 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.

摘要： A light emitting diode (LED) lighting device includes a circuit for receiving an input power from a power source and outputting a rectified power, an LED unit including a plurality of LED channels connected in series, each LED channel having a front end and a rear end, a current sensing resistor, and a switch circuit unit. The switch circuit unit includes a plurality of switches, and 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. Forward voltages of the LED channels are unevenly redistributed so as to keep power consumption between the Nth switch and the (N+1)th switch substantially same, and N is a positive integer.
