Disclosed herein is a light-emitting diode (LED) bar which can be desirably bent at various angles in vertical and lateral directions. The bendable LED bar includes: a plurality of LED units each configured such that one or more LEDs are surface-mounted on a rectilinear bar-shaped printed circuit board (PCB) substrate; and one or more bending units electrically connected between the plurality of LED units spaced apart from each other at regular intervals in a front-back direction, and configured to connect the plurality of LED units in a joint fashion so that each of the plurality of LED units can be bent within a predetermined angle. Each of the bending units includes a plurality of rectilinear spring-shaped connection copper lines and a casing mold. The casing mold enables the LED units to be bent in vertical and lateral directions.
