Abstract

The present invention relates to an LED florescent lamp. The LED florescent lamp comprises: first through fourth connection pins; first through fourth capacitors having one end connected to first through fourth connection pins, respectively; and an LED array circuit connected, at one end, to a first node to which the other end of the first capacitor and the other end of the third capacitor are connected and connected at the other end, to a second node, to which the other end of the second capacitor and the other end of the fourth capacitor are connected, with the LED array circuit having at least one LED array and a constant current circuit for supplying a constant current to the LED array. As the LED fluorescent lamp according to the present invention can utilize ballasts of diverse forms that are already installed within a conventional florescent lamp without any change, it can substitute for the conventional florescent lamp without having to attach any additional device or change wires.
