Abstract:
1. A light-emitting diode package, comprising: a lead-frame, comprising two first pieces with a horizontal top surface above a substrate, two third pieces below a substrate with horizontal bottom surfaces opposite of the side that is towards the substrate, and two second pieces with vertical surfaces opposite to the side that is towards the substrate, wherein the two second pieces connect the first and third pieces; at least a light-emitting diode chip, disposed on one of the first pieces of the lead-frame and electrically connected to the lead-frame; and an encapsulant, encapsulating the light-emitting diode chip and a first part of the lead-frame, wherein a second part of the lead-frame is exposed out of the encapsulant, wherein the encapsulant comprises a casing encapsulating first partial regions of the first pieces, and wherein a roughened surface is present on said vertical surfaces of the second pieces, said horizontal bottom surfaces of the third pieces, and portions of said horizontal top surface between the casing and the light-emitting diode chip where the roughened surface is suitable to scatter the light emitted from the light-emitting diode chip.
