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.

Light unit for LED lamp and method for the same

An LED lamp with replaceable light unit according to the invention includes a heat dissipation housing, a metal connector, a driver circuit board, a light unit slice, a pad and a shade. The heat dissipation housing has an opening at one end and a joint portion at another end. The metal connector is disposed to the joint portion of the heat dissipation housing. The driver circuit board disposed inside the heat dissipation housing to electrically connect with metal connector. The light unit slice and the pad are disposed inside the opening, and the light unit slice is electrically connected with the driver circuit board. The shade is disposed inside the opening. The LED lamp with replaceable light unit can be realized by the assembly of the above elements according to the different preferred embodiment of the present invention.
