Patent ID: 7800124

Claim:
A light-emitting device comprising: a LED chip; a chip mounting member having a heat transfer plate and a conductor pattern: said heat transfer plate being made of a heat conductive material and one surface side of which said LED chip is mounted on, said conductor pattern being formed on the one surface side of said heat transfer plate through an insulating part and electrically connected to said LED chip; a sheet-shaped connecting member disposed on the other surface side of said heat transfer plate to connect said heat transfer plate to a metal member for holding said chip mounting member, said connecting member having an electrical insulating property and connecting said heat transfer plate and said metal member thermally to each other; a sealing part which is made of an encapsulation resin and seals the LED chip; an optical member which has a convex light output surface and is piled on the sealing part; and a dome-shaped color converting member which is a molding made of a translucent material and a phosphor, the phosphor emitting a light having a color different from an emission color of the LED chip when excited by the light emitted from the LED chip, the color converting member covering the optical member from the light output surface side of the optical member, the color converting member being arranged so that an air layer is formed between the light output surface and the color converting member, wherein said connecting member is made of an epoxy resin sheet which includes a filler and whose viscosity is reduced by heating, and wherein said epoxy resin sheet has a high flowability in heating.
