Abstract

An LED package and method thereof include an insulation plate, and a metal board disposed on the insulation plate and etched to form a cavity, wherein the metal board is etched to partially expose the insulation plate to form the cavity. The LED package and method also include an LED chip configured to be mounted inside the cavity, and an encapsulation member filling the cavity, wherein the encapsulation member comprises an epoxy resin. The LED package and method include a through-hole configured to be formed on the insulation plate where the LED chip is mounted. The through-hole enables portions of the LED chip to be exposed, and a metal configured to fill the through-hole to form an electrode to be electrically connected to the LED chip.

Claims (14)

1. An LED package, comprising:

an insulation plate;

a metal board disposed on the insulation plate and etched to form a cavity, wherein the metal board is etched to partially expose the insulation plate to form the cavity;

an LED chip configured to be mounted directly on the insulation plate inside the cavity;

an encapsulation member filling the cavity, wherein the encapsulation member comprises an epoxy resin;

a through-hole configured to be formed on the insulation plate where the LED chip is mounted, wherein the through-hole enables portions of the LED chip to be exposed; and

a metal configured to fill the through-hole to form an electrode to be electrically connected to the LED chip.

2. The LED package of claim 1 , wherein the encapsulation member further comprises a fluorescent material configured to convert light having a short wavelength of the LED chip into multi-wavelength light having a wide range of the wavelength of the light.

3. The LED package of claim 1 , wherein the portions comprise two or more through-holes having a same number terminals of the LED chip.

4. The LED package of claim 1 , wherein the encapsulation member comprises a fluorescent material that converts light, having a short wavelength, of the LED chip into multi-wavelength light, having a wide range of the wavelength.

5. The LED package of claim 1 , wherein the metal board is formed of a metal material.

6. The LED package of claim 1 , wherein the insulation plate is formed of a thermal insulation material.

7. The LED package of claim 1 , wherein a plating process is performed to fill the metal into the through-hole.

8. The LED package of claim 1 , wherein the metal is plated to extend from the through-hole up to the insulation plate to form the electrode on the insulation plate.
