Abstract: A lighting device may be provided that includes a light emitting module including a substrate and a light emitting device disposed on the substrate; and a case receiving the light emitting module therewithin and including an upper case disposed on the substrate and a lower case in which the substrate is disposed. The lower case includes a seating portion which is coupled to a heat sink. The seating portion is either a projection projecting outward from the outer surface of the lower case or a recess which is formed by digging inward the outer surface of the lower case.

Abstract: A LED lighting device includes a light source module including a plurality of light emitting device, at least one heat radiating member including the at least one light source module disposed therein, a side frame which is coupled to both sides of the heat radiating member respectively, and a support frame which is coupled to one side of the side frame and supports the side frame.

Abstract: A lighting module may be provided that includes: a light emitter; a clad metal substrate which is disposed under the light emitter; an insulating structure which insulates the light emitter from the clad metal substrate; an optical structure which is disposed on the light emitter; and a case which is disposed on the optical structure and is coupled to the clad metal substrate, wherein the light emitter includes a semiconductor based light emitting device.
