Abstract
An LED package with an extended top electrode and an extended bottom electrode is made from a single metal sheet, one manufacturing process embodiment includes: preparing a piece of single metal sheet, forming a first metal and a coplanar second metal, mounting an LED on an inner end of the first metal, wire-bonding top electrode to an inner end of the second metal, encapsulating at least the LED and the bonding wire with a protection glue, bending an outer end of the first metal upward twice 90 degrees to form a top flat as an extended top electrode of the package, and bending an outer end of the second metal downward twice 90 degrees to form a bottom flat as an extended bottom electrode of the package.

A manufacturing process for making a light emitting diode (LED) package having a top surface, an opposing bottom surface, a left surface, and an opposing right surface, wherein the left and the right surfaces extend between the top and bottom surfaces, the manufacturing process comprising:
- mounting an LED on an inner end of a first metal, wherein the LED is electrically coupled to the first metal, and wherein an outer end of the first metal terminates at an outer edge;
- electrically coupling the LED to an inner end of a second metal by a metal wire, wherein an outer end of the second metal terminates at an outer edge;
- bending the outer end of the first metal in a first direction along the left surface of the LED package and along the top surface to form a top electrode of the LED package;
- bending the outer end of the second metal in a second direction opposite of the first direction along the right surface of the LED package and along the bottom surface to form a bottom electrode of the LED package;
- and
- enclosing the LED and the metal wire in a protection molding,
- wherein said bending the outer end of the first metal places the outer edge of the first metal at the top surface of the LED package, and
- wherein said bending the outer end of the second metal places the outer edge of the second metal at the bottom surface of the LED package.
A manufacturing process for making a light emitting diode (LED) package, the manufacturing process comprising:
- mounting an LED on an inner end of a first metal, wherein the LED is electrically coupled to the first metal, and wherein an outer end of the first metal terminates at an outer edge;
- electrically coupling the LED to an inner end of a second metal by a metal wire, wherein an outer end of the second metal terminates at an outer edge;
- bending the outer end of the first metal in a first direction and again bending the outer end of a first metal in the first direction at a different location on the first metal to form a top electrode of the LED package;
- bending the outer end of the second metal in a second direction opposite of the first direction and again bending the outer end of the second metal in the second direction at a different location on the second metal to form a bottom electrode of the LED package;
- and
- enclosing the LED and the metal wire in a protection molding,
- wherein the inner ends of the first metal and the second metal are enclosed in the protection molding, and wherein the outer ends of the first metal and the second metal exit out from the protection molding on opposite surfaces of the LED package.
