Patent ID: 8445936

Claim:
An integrally formed high-efficient multi-layer light-emitting device, comprising: a heat dissipation seat, including a chamber having an accommodating space, the chamber being formed on a top of the heat dissipation seat, a groove being formed in a bottom of the chamber, the groove having two inclined inner sidewalls so that the light is reflected out of the chamber by the two inclined inner sidewalls, the heat dissipation seat having at least one through hole longitudinally formed therein; a plurality of light-emitting dies, disposed in the groove, the light-emitting dies being spaced away from each other, the light-emitting dies being electrically connected with each other by wire-bonding with use of metal wires; and a lead frame, disposed in the at least one through hole, an upper and a lower portions of the at least one through hole being sealed by a sealant so that the lead frame is fixed in the at least one through hole, the lead frame including two conductive rods and a sleeve, the two conductive rods being disposed in the sleeve, two ends of each conductive rod being extended out of the sleeve, the two conductive rods being electrically connected with the light-emitting dies by wire-bonding with use of metal wires.
