Abstract

The present invention provides an LED fluorescent lamp, comprising: a main body selectively mounted on a ceiling; a power supply unit accommodated in the main body to receive an alternating current voltage from an external source, to convert the received voltage into a direct current voltage, and to output the converted direct current voltage; a first LED-driving unit accommodated in the interior of the main body and electrically connected to the power supply unit to receive the converted direct current voltage and to drive a plurality of LEDs; a front cover which contacts both ends of the main body to protect the first LED-driving unit; a second LED-driving unit mounted on a portion of an outer surface of the main body adjacent to the front cover, and electrically connected to the power supply unit to receive the converted direct current voltage and to drive other LEDs; a side cover which selectively contacts both ends of the main body and both ends of the front cover; and a light diffusion unit mounted on a portion of the outer surface of the main body and selectively coupled to the side cover to protect the second LED-driving unit and to collect and diffuse light emitted by the operation of the second LED-driving unit.
