The present invention relates to an integrated light emitting diode (LED) lighting device for extended control, which comprises: a plurality of first to N^th converters for receiving AC to convert the same into DC; an LED module for receiving the DC from the first to N^th converters to emit light; and a plurality of first to N^th on/off switches (1, 2, 3, ..., N) which are individually connected to the first to N^th converters, and control power application. The first to N^th converters include an LED converter circuit in which output units thereof do not collide even if the output units are combined to each other. According to the present invention, a constant current constant voltage source is directly generated by a primary side auxiliary winding, and is switched into the first to N^th converters which can basically perform constant current driving needed to drive the LED, and can perform electrostatic force driving at the same time so as to control the brightness of an LED module, so a separate dimming circuit is unnecessary, thereby saving costs for installation and also, saving standby power consumption. |
