Abstract
A method for manufacturing a light unit for LED lamp first provides an aluminum substrate, which is surface-treated to form a thin aluminum oxide insulating layer thereon. A circuit board is attached to the insulating layer and includes a through hole to expose part of the insulating layer. An LED die is mounted to the exposed part of the insulating layer, and two bonding wires electrically connect the LED die and the circuit board. A wall is formed on the circuit board to enclose the LED die and the bonding wires. Finally, plastic material is dispensed into the wall to form a lens.
