Abstract
A light emitting diode (LED) lamp includes a lamp housing formed of a pair of housing members connected to each other in a horizontal direction. A printed circuit board (PCB) is detachably connected to an inside of the lamp housing, and includes at least one LED mounted to one surface of the PCB. A power supply unit (PSU) is electrically connected with the PCB in the lamp housing to supply power to the PCB.
