Patent ID: 8507299

Claim:
A manufacturing method of a light emitting diode (LED) package, the method comprising the steps of: forming through holes on a flat-panel type substrate, the substrate made of a light-transmitting material; mounting LED chips at upper parts of the through holes to cover the through holes of the substrate, the LED chips being supported by the substrate; bonding the LED chips and the substrate with wires formed through the through holes; coating a top surface of the substrate with a molding material to cover all sides and top surfaces of the LED chips such that a side surface of the substrate and a side surface of the molding material are substantially coplanar, the molding material being formed of a transparent material; coating a bottom surface of the substrate with an encapsulant to encompass the bonded wires such that the side surface of the substrate, the side surface of the molding material and a side surface of the encapsulant are substantially coplanar, the encapsulant including a resin and a reflective material distributed in the resin; and after curing the molding material and the encapsulant, cutting the LED package into unit LED packages along dicing lines, wherein: the LED package is cut into the unit LED packages such that each of the unit LED packages includes a portion of the substrate, a portion of the molding material and a portion of the encapsulant, a side surface of the portion of the molding material, a side surface of the portion of the substrate and aside surface of the portion of the encapsulant are disposed in this order, in a direction of thickness of the substrate, to be substantially coplanar, and the substantially coplanar surfaces of each unit LED package form outer surfaces of the unit LED package, and wherein the molding material is made of resin mixed with a fluorescent material, is molded around the LED chip mounted on the substrate to be directly in contact with a top surface of the LED and lateral surfaces of the LED chip and is coated at a predetermined thickness thereon; and wherein the molding material has a wave-length conversion feature, the encapsulant has a reflectivity feature, and the substrate has a transparency feature, and wherein the molding material and the encapsulant do not directly contact each other and are separated by the substrate having the optical feature of transparency.
