Abstract
A leadframe includes two spaced apart conductive legs, each of which includes a base section, and a first extension section extending from a bottom end of the base section in a direction away from the other one of the conductive legs. At least one of the conductive legs further includes a second extension section that extends from a top end of the base section thereof in the same direction as the first extension section for fixing the light-emitting diode chip. The heat generated by the light-emitting diode chip can be dissipated through a shortest heat-dissipating route, thereby increasing the heat-dissipating rate.
