The present invention relates to an LED light bulb having a coupling structure where a lens is combined, by an ultrasonic wave deposition, with a heat radiating portion having an LED module installed. Provided is an LED bulb comprising the LED module emitting light; the heat radiating portion having the LED module and emitting heat generated from the LED module; and the lens coupled to a front of the heat radiating portion, wherein the heat radiating portion includes a flange for coupling the lens, a periphery part of the lens is bent towards the rear for shielding the flange, and the bent periphery part is heat-welded to the flange by the ultrasonic wave. |
