Hermetic light-emitting device

A hermetic light-emitting device, comprising:

• a heat dissipation member comprising a first through-hole, at least one fin member, a first surface, and a second surface opposite to the first surface, wherein the at least one fin member is disposed on the second surface, and the first through-hole is formed between the first surface and the second surface;
• a circuit substrate including a plurality of conductive traces and a second through-hole disposed corresponding to the first through-hole;
• at least one light-emitting element disposed on the circuit substrate and electrically connected to the plurality of conductive traces, wherein the circuit substrate is disposed adjacent to the first surface of the heat dissipation member with the at least one light-emitting element positioned opposite to the heat dissipation member;
• a plurality of electrical wires passing through the first and second through-holes, electrically connected to the plurality of conductive traces so as to externally supply electrical power to the at least one light-emitting element;
• a sealing material filling the first and second through-holes;
• a seal pad member including a pad opening and disposed on the first surface of the heat dissipation member, wherein the circuit substrate is disposed in the pad opening;
• and
• a cover member disposed over the at least one light-emitting element and against the seal pad member.
