Abstract:
1. A method of manufacturing a light emitting device, said light emitting device comprising: an LED chip, a mounting substrate mounting said LED chip; a dome-shaped color conversion member made of a transparent resin material and a fluorescent material which is excited by a light emitted from said LED chip to emit a light of a color different from a luminescent color of the LED chip, said dome-shaped color conversion member being bonded on the mounting substrate to surround the LED chip, and an encapsulation member disposed in a space confined between the mounting substrate and the color conversion member to encapsulate the LED chip, said encapsulation member being made of an encapsulation resin material, wherein said encapsulation member has a convex lens-shape such that a light output surface of the encapsulation member is held in an intimate contact with an internal surface of the color conversion member, wherein said method comprises the steps of: (a) mounting said LED chip to said mounting substrate, and connecting said LED chip to said mounting substrate by means of bonding wires; (b) covering said LED chip and said bonding wires with an uncured first encapsulation resin material which becomes a part of said encapsulation member; (c) filling up inside of said color conversion member with an uncured second encapsulation resin material which is the same material as said first encapsulation resin material and becomes the other part of said encapsulation member so as to position the color conversion member on the mounting substrate; and (d) curing at the same time each of said first and second uncured encapsulation resin materials to form said encapsulation member.
