Patent ID: 8569777

Claim:
A package structure adapted for mounting at least one light emitting diode (LED) die, said package structure comprising: an insulating housing; and a lead frame unit including: two spaced-apart conductive bodies, each of said conductive bodies having opposite first and second conductive terminals spaced-apart from each other along an axial direction, said first conductive terminal extending into said insulating housing, said second conductive terminal being exposed outwardly of said insulating housing, wherein each of said conductive bodies further has two side edges spaced-apart from each other along a transverse direction perpendicular to the axial direction and extending substantially in parallel to each other along substantially the entire length of said each conductive body, and each of said conductive bodies being integrally formed and having a protrusion that extends in a transverse direction from a side surface thereof and that defines a step contoured structural body in an upper section of said conductive body and a ledge being contiguous with a notch formed within said structural body in a lower section of said conductive body; said notch and said ledge being configured into a concave-convex structure disposed along each of said two side edges, wherein each said concave-convex structure is surrounded by said insulating housing; wherein said each concave-convex structure of at least one of said two conductive bodies has said ledge and notch formed along a respective one of said two side edges of said at least one conductive body; wherein, in said each concave-convex structure, said protrusion, said ledge and said at least one notch are disposed each with respect to the other along a direction perpendicular to said axial direction and said transverse direction; and wherein said at least one conductive body, at a portion thereof surrounded by said insulating housing, has a first width defined along said transverse direction between outermost edges of said protrusions formed at said opposite side edges, and wherein said first width exceeds a width of said second conductive terminal exposed outwardly of said insulating housing.
