Abstract: A heat dissipating base for a light-emitting element sufficient to dissipate generated heat without additional means of dissipating includes a first base plate and a second base plate formed on the first base plate. The first base plate includes first sidewalls. The second base plate includes second sidewalls. The first base plate defines a first groove, the first groove passes through one first sidewall to form a first cutout. The second base plate defines a second groove, the second groove passes through one second sidewall to form a second cutout. The first cutout and the second cutout correspond to each other and cooperatively form a heat dissipating opening. The first groove and the second groove correspond to each other and cooperatively form a channel for dissipating heat. A light emitting device having such heat dissipating base is also provided.
