ABSTRACT:
An LED package including a lead-frame, at least an LED chip and an encapsulant is provided. The lead-frame has a roughened surface, the LED chip is disposed on the lead-frame and electrically connected to the lead-frame, and the roughened surface is suitable to scatter the light emitted from the LED chip. In addition, the encapsulant encapsulates the LED chip and a part of the lead-frame, and the rest part of the lead-frame is exposed out of the encapsulant.
